The screw press is a very practical equipment that reduces people's labor intensity during use. One machine can meet a large number of material handling needs, not only improving everyone's working environment, but also making people's work simple and convenient. Drive the reducer to push the blade shaft to rotate, push the helix angle forward, and then squeeze the material into the extrusion tube. The water in the waste residue is squeezed out under the transport, rotation and extrusion of the spiral blade, and the extruded material is discharged from the discharge port. The liquid flows out from the sieve holes and is concentrated in the water tank to achieve the purpose of solid-liquid separation. The discharge resistance and the size of the discharge port can be changed.

1. The contact surface with the material is small and the friction is low, which can improve the efficiency of extrusion and dehydration. No clogging or coiling;

2. Low energy consumption, low investment and high efficiency;

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

4. The driver is directly driven by the shaft, which ensures stable and reliable operation and energy saving;

5. Use an adjustable partition outlet to increase the extrusion pressure and improve the dehydration rate;

6. Sustainable dehydration and strong working ability. Compared with traditional dehydration methods, it has the advantages of good dehydration effect, strong working capacity, low energy consumption, and simple operation.

Screw presses are widely used and can be used for squeezing and dehydrating extraction waste residues such as residues, xylose residues, and wine troughs, solid-liquid separation of kitchen waste, fruit and vegetable waste organic solid waste, and dehydration reduction of hazardous wastes such as paint residues and dry film residues. Juicing of fruits, vegetables and other rhizome flowers and fruits, extraction and dehydration of solid wastes such as straw pulp and straw digester.

How to solve the problem of material jamming in screw press?

The principle of the traditional screw press is to continuously transport the materials in the feed hopper from the feed end to the feed end based on the promotion of the screw. According to the mutual restraint of the pressurized slag discharge door and the screen, the material capacity is reduced and part of the liquid is It is discharged through the screen under the action of screw extrusion force. When the feed hopper stops feeding, the compacted material existing between the spiral and the screen loses the driving force for continuous feeding, and is stuck between the screen and the spiral and cannot be cleaned.

In the early days of the screw press, manpower was used to open the screen and clean the materials stuck in the middle. For some processes that did not have hygienic requirements, cleaning materials could not be considered. However, when processing some food materials and some materials that cause chemical reactions at room temperature and gases to cause taste, they cannot be used. The accepted material remains between the spiral and the screen for a long time, and the equipment needs to be cleaned every time it is used.

By adjusting the overall design of the spiral, the new screw press can discharge the residue between the screen and the spiral when the feed is stopped, and install a mobile jet flushing equipment outside the screen to complete the jet flushing of the juice tray outside the screen. Clean.

The main features of the screw press operating principle:

1. The use of shaftless spiral has a small contact surface with the material and low friction, which can improve the extrusion efficiency. No clogging, no coiling;

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

3. The driving mechanism adopts shaft-mounted direct drive mode, which ensures smooth and reliable operation and energy saving;

4. The outlet is equipped with a spring partition to increase the extrusion force and improve the dehydration rate;

5. Except for the import and export, the other parts adopt sealed structures and the use environment is clean and hygienic.
