At present, when the screen is replaced and inspected, the guide chain or the crane is manually used, and the entire replacement work is carried out under the lifting hoist ring. When the screen of the large sieving machine of the 4~5 layer structure is replaced, the process is too cumbersome. The development of a pneumatic lifting device is a good solution to this problem. It is lifted by a cylinder fixed to the base of the screen box or lifted for a certain level of screen to inspect or replace the screen or seal. This kind of operation is easy and fast, which reduces the labor intensity of workers and avoids unnecessary damage.
The entire upper screen is turned over by a hinge mechanism using a pneumatic or hydraulic cylinder to open the screen for easy inspection and quick change of screen or seal.
The enlargement of the screen surface makes the diameter of the rocking screen machine up to 2.9 m. If the screen surface is made into a whole, it is difficult to replace and process, and it is difficult to ensure the flatness of the screen surface. Therefore, a fan-shaped block structure is used, and several blocks are used. The screen assembly spliced out a complete circular screen.
The tumbler screens are designed as building blocks and stacked on top of each other. Several sets of clamping devices are used to tighten the whole of the screen box, and the sealing ring between the layers of the screen box is sealed and layered. The size of the clamping force and the consistency of the tension of the individual clamping assemblies determine the performance of the screen. In addition, vibration and temperature can change the size of the seal during the use of the seal. Especially on the multi-layer screen, the dimensional change accumulates and the situation is more serious. Therefore, the clamp assembly needs to be tightened again after a certain period of time. The powerful spring clamping device uses a set of disc springs to achieve rapid tensioning and uniform tension of the clamping bolts, ensuring stable operation of the overall screen frame.
Bouncing ball cleaning. In order to reduce the hole blocking and ensure the effective screening area, the screen can be cleaned by a bouncing ball. A metal hole support plate is added under the screen to place the bouncing ball between the support plate and the screen. As the screen moves, the ball bounces up against the screen to remove particles stuck in the mesh. This method is the easiest, easy to design, manufacturing and operational maintenance for most granular products. Bouncing ball is generally made of rubber material, with low wear and low noise, and is easy to meet the special requirements of food and medicine processing.
The tumbler screen adopts the principle of artificial screening, the screening accuracy can reach 90-95%, and the output is 5-10 times that of the ordinary vibro sifter. The following will mainly list the differences between the vibro sifter of the tumbler screen:
Working principle
The tumbler screen is to imitate manual sieving, and the material makes non-linear three-dimensional motion on the sieve surface, both circular motion and upward arcing motion, similar to manual sieving.
The vibro sifter is driven by a vertical motor, and the material movement trajectory is horizontal, inclined, and vertical three-dimensional movement, which can be screened, sorted, dedusted and filtered.
Application material and precision
Due to the artificial screening, the tumbler screen has added a screen cleaning device, which is more suitable for irregular or wet materials within 500 mesh, overcoming the risk of vibro sifter clogging, and the accuracy can reach 90-95%.
Vibro sifter is an unbalanced movement of destructive violence. The material is screened by the principle of vibration, and sometimes the material will be destroyed. Therefore, for some granular crystalline coke brittle materials, it is recommended to use a tumbler screen, whose sieving accuracy can reach more than 95%.
Throughput
The output of vibro sifter and tumbler screen is basically the same for the coarse material with 30 mesh, but for the fine material with 500 mesh, the output of tumbler screen is much higher than that of ordinary vibro sifter, which is 5-10 times that of vibro sifter.
Different service life
Vibro sifter uses the principle of high-speed vibration to screen materials, which is very destructive to the machine. After a long time, it is easy to cause vibration, deformation and damage to the screen. The tumbler screen has a slight elliptical swing motion without high-speed vibration, which can overcome this problem.
As a common food additive, sugar is inseparable by tumbler screen from our daily lives. Sugar can be divided by tumbler screen into three categories: monosaccharides, oligosaccharides, and polysaccharides. These three categories can be divided by tumbler screen into more species. The term "tang" in our mouth generally refers to sucrose in oligosaccharides. With the progress and development of society, there are more and more types of sugar, such as glucose, xylitol, citric acid, starch sugar, proteoglycans.These sugars screened by tumbler screen are widely used in food, medicine, beverage, and day.
With the increase in demand and the wide application, the quality requirements for sugars have also increased accordingly by tumbler screen. The production process of sugars is high, and it is often required to be clean and uniform. However, the disadvantage of the viscous and fragile sugars increases the difficulty of screening.
In the past, conventional vibrating screens and linear screens were graded and filtered by high-speed vibration. The high-speed vibration often has the consequence that the particles are easily broken, the yield is reduced, and the throughput is very low, which is undoubtedly greatly reduced. The efficiency of the manufacturer; and the traditional vibrating screen due to its working principle, the large model vibrating screen is not good (1500 or more), the vibration motor is easy to damage, the frame is easy to crack, and the annual maintenance cost is also very high.
Tumbler screen is a new type of high-efficiency screening equipment. Compared with vibrating screen, tumbler screen is not well understood by many users, but it is in the field of fine screening, regardless of From the processing volume per unit time, the technology, or the screening accuracy, the protection of the consumables such as screens, etc., tumbler screen has become the strongest in the screening equipment. Tumbler screen is the best fine screening machine in China. The working principle is similar to manual movement, processing volume, precision, and the service life of the screen is 5-10 times that of ordinary vibrating screen. The precision can reach more than 90%, due to the three-dimensional movement of the swing screen. Smooth, the life of the screen is greatly improved, and the maintenance rate of the whole machine is extremely low. Only one labor cost and maintenance fee can directly save tens of thousands of yuan for the enterprise in one year. The swing screen is a very efficient fine screening machine, which is in line with all. Fine and ultra-fine range of powder and particulate materials for difficult to handle materials.
The structural design of tumbler screen is closed, and it is dust-free and clean, which can better ensure the cleanliness of the materials. Because of the balance of weight, the sieve machine has low vibration and low noise, which meets the requirements of environmental protection. Tumbler screen can meet the requirements of different customers and can greatly improve the screening efficiency. The automatic tensioning of tumbler screen and the various automatic cleaning screen systems make the swing screen mesh extremely efficient and extremely long-lived. The screen change is quick and easy to complete in 10 minutes; the tumbler screen adopts a pyramid-shaped reinforced base. The tumbler screen works more smoothly.
Tumbler screen can provide high frequency vibration, through which the sieving and particle grading of the material can be achieved. Therefore, it has a wide range of applications in many fields.
Granular foods in life are not uncommon, such as flour, starch, salt, milk powder, rice, and grains.
These foods need to be screened before they are put on the market, and some protective measures are needed.
The sealing performance of Tumbler screen is good, the fully enclosed dust does not fly, and the screening efficiency is high and the precision is high.
Easy to disassemble, easy to clean, no sanitary corners, in line with food-grade GMP requirements, the discharge port can be adjusted 360 degrees.
It is convenient to connect with the site. A variety of screen cleaning devices are specially designed to make the screen meshing rate high, fast discharging, high output, and new grid structure;
Tumbler screen has long service life, the mesh does not change, the net change takes only 3-5 minutes, the parts have no dead angle, it is easy to clean and disinfect thoroughly, the energy consumption is low, the startup is fast, the noise is low, no foundation installation is required, and any place need can be placed.
Tumbler screen solves the problem that the granules and powdery substances fly when sieving by means of sealing.
The steps of the tumble screenneed to be checked before starting
1. The first check of the start-up work is to find whether there are any sundries in the machine, that is to say, all the items need to be cleaned up.
2. The most important step is to see if the screws of each component are tightened.
3. Another one is to see if the power supply motor and other accessories can work properly.
4. When the three points mentioned above are completed, the operation can be started.
The contents of the tumbler screen need to be checked when shutdown
1. Follow the instructions exactly to finish the work procedure. It is best not to change the step of the operation.
2. Carefully clean the debris in the machine to avoid hidden dangers caused by it.
3. Keep the operation mode of the sieve machine at rest.
4. The surrounding environment of the sieve machine should be neat and tidy, try not to be contaminated with dust.
5. Do not put anything that is irrelevant around the tumbler screen.
Precautions
1. Always check the conditions of the sieved material. If the material has a knot or the color is deviated, it is necessary to remove the particles and solve the subsequent material changes.
2. When using the tumbler screen, it not only requires its ability, but also valued the discharging effective particles. Therefore, there are two capacity requirements for the sieve surface: the first is its ability to handle the material, that is, it can sieve the particles, the other is its efficiency－the quality of the material.
3. In the operation, theoretically, the particles smaller than the sieve holes should pass through the screen mesh completely, but this is not the case in actual operation, which is determined according to the vibration force and the material characteristics. Therefore, more or less, some of them cannot pass through the mesh, while become waste materials.
4. The power of the tumbler screen cannot be started or the swinging amplitude is too small. First, we must first check whether the motor is normal, or it may be the damage of the motor circuit. Then we should consider whether the voltage is too small. If these three points’ information are normal, then we have to check whether too much material on the screen surface leads to excessive load. Finally, check if the matched accessories on the screen surface are damaged or not.
5. If the material movement during screening is not normal, there may be scars in thetumbler screen. The other case is that the device is unstabilized. If the rotation is slow in the work, and the bearing is too hot, it does not need to check anything, this is because the usual maintenance does not keep up or lubricate too much.
6. The quality of material is not well, it may be that the discharge hole is not open, or the tension of screen mesh is not enough.
7. Before the tumbler screen operation, the fuel tank should be inspected. If the oil level exceeds the standard height, it will cause problems such as temperature rise and amplitude instability. If the oil in the fuel tank is little, which will cause the running shaft to wear.
