What is a multi-plate screw press machine?

The multi-plate screw press machine is a supporting equipment for the fouling grid. It is composed of a feed hopper, a pressing screw, a spiral tube, a slag discharge tube and a driving device. The slag picked up by the grid or filtered filter slag enters the spiral tube from the feed hopper, and is squeezed and dehydrated under the action of the squeezing screw. The water squeezed out from the material is collected into the water receiving basin and discharged by the drain pipe. The material is compressed and discharged through the slag discharge pipe, which can greatly reduce the weight and volume of debris and other debris. The multi-plate screw press machine is composed of drainage area, feed area, screw conveying area, and discharge area. The grid slag enters the material area, and is compacted in the compaction zone by a multi-plate screw press machine, and then the grid slag is discharged, and the waste liquid flows into the collecting pipe from the grid.

Main features of multi-plate screw press machine

1. The shaftless screw is adopted, the contact surface with the material is small, the friction is low, and the extrusion efficiency can be improved. And there is no blockage, no entanglement phenomenon;

2. The equipment is made of stainless steel, with high strength, good corrosion resistance and long service life;

3. The drive device adopts the shaft-mounted direct drive mode, which is stable and reliable in operation and energy saving;

4. Equipped with spring baffle to increase the squeezing force and increase the dehydration rate;

5. Except for the inlet and outlet, the rest adopt a sealed structure, and the environment is clean and hygienic.

Several conditions for a good quality screw press

The quality of presses on the market is uneven. How can I buy a machine that is satisfactory and inexpensive? The important thing is to know what are the requirements for a good quality multi-plate screw press machine in order to be more handy in the purchase process.

Here is a brief list for everyone:

Condition 1: If you want the press to have high power and output during the production process, it is not necessary that the larger the reducer, the better. Large torque is the key to the operation of the machine.

Condition 2: The dewatering effect of the material is determined by factors such as the screen barrel, reinforcing ribs, and the size of the screen barrel gap.

Condition 3: The softness and hardness of the material itself, the particle size and other factors cannot completely determine the dehydration rate, and the change of the spiral curve inside the press is the most important thing.

Condition 4: Whether the design of the machine is reasonable and whether the operation is simple and easy to learn.

Condition 5: Whether the after-sales maintenance of the machine is guaranteed during the use of the machine.

Condition 6: Whether to agree to the field test. A good advertisement is not as good as a good effect. The field test can show the good quality and good effect of the machine, and it can't be mixed with a little fake.

Advantages of multi-plate screw press machine

1. The production cost is low, the price is appropriate, the model is complete, and the equipment investment is saved, and it is an economical equipment;

2. Large output, continuous discharging, not easy to block, return, etc., fast speed, small back flow, saving time and effort;

3. In the process of pressing and dewatering, the material is conveyed smoothly, and the pressing and drying humidity is uniform;

4. Small footprint and space saving;

5. Simple operation and easy to use;

6. There are many choices and different machines for different materials: single multi-plate screw press machine, special multi-plate screw press machine (variable diameter multi-plate screw press machine), double multi-plate screw press machine

7. The screen of the sieve barrel is made of pure hand-made trapezoidal wire, generally 50 wires 0.5mm, smaller ones can be woven from 30 to 20 wires (0.3m—0.2m)

Disadvantages of multi-plate screw press machine

1. When the multi-plate screw press machine is used for squeezing and dehydrating fruits and vegetables, due to the limitation of the screen gap of the sieve barrel, there will be a small amount of residue in the juice after pressing, and the liquid will appear turbid. For example, for the juice of juicy fruits such as apples and pears, even if the screen gap is woven to a small 0.2m, the solid-liquid separation cannot be completely achieved, and the juice will have some turbidity, which cannot achieve a clear and visible effect.

2. When the multi-plate screw press machine is used to squeeze the miscellaneous materials such as domestic waste, kitchen waste and medical waste, iron filings, iron chips, sharp and hard objects cannot enter the body to prevent internal damage to the machine and affect normal operation.

3. The level of material dehydration rate has a certain relationship with factors such as weather and climate, material storage time, material type, material state and so on. For example: fresh fruits and vegetables have different juice yields from fruits and vegetables stored for a period of time; northern fruits and southern fruits have different juice yields; different climates in rainy and dry seasons have different dehydration rates of materials; crushed materials are more straightforward The dewatering rate of the squeezed material is higher...etc.

4. Since the small multi-plate screw press machine has no hydraulic system, it needs to manually open and close the forced door. When the machine is working, the staff cannot be left.

5. When the machine is not turned on for more than 24 hours, all residues in the machine should be cleaned up (a water gun is recommended) to prevent internal blockage and affect the next normal use.

6. The transmission system, transmission parts, bearings, etc. are regularly filled with lubricating oil or grease for maintenance.

7. When working, it should be noted that the oil temperature rise of the hydraulic system should not exceed 60°C, and the temperature rise of each bearing in the transmission system should not exceed 40°C at room temperature.

With the increasing demand for industrial filtration, the market development of the chamber filter press has also made great progress. Generally, we mainly consider the service life and filtration quality of chamber filter press when purchasing chamber filter press. We know that the service life of a chamber filter press is related to the performance and operation method of the chamber filter press. Enterprises should pay attention to the operation method and operation method when operating
