How to solve the problem of screw press material stuck?

The principle of the traditional screw press is to continue to transport the material in the hopper from the feed end to the feed end according to the promotion of the screw, and to reduce the material capacity according to the mutual restraint of the pressurized slag discharge door and the screen, so that part of the liquid Under the action of screw extrusion force, it is discharged according to the screen. When the feed hopper stops feeding, the compacted material existing between the screw and the screen loses the driving force for continuous feeding, and it is stuck between the screen and the screw and cannot be cleaned.

Early screw presses used manpower to open the sieve to clean up the materials stuck in the middle. Some technological processes without hygienic requirements cannot consider cleaning materials, but processing some food materials and some normal temperature states and gases cause chemical reactions to cause taste materials, which cannot Receiving material exists 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 screw, the new screw press can discharge the slag between the screen and the screw when the feeding is stopped, and a mobile jet washing device is installed outside the screen to complete the jet washing of the juice tray outside the screen cleaning.

The main features of the working principle of the screw press:

1. Shaftless screw is used, which has a small contact surface with the material and low friction, which can improve the extrusion efficiency. No blockage, no coiling phenomenon;

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

3. The drive mechanism adopts shaft-mounted direct drive mode, which is stable and reliable in 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 adopts a sealed structure, and the use environment is clean and hygienic.

Screw presses are widely used, and can be used for extrusion dehydration of residues, xylose residues, wine tanks and other extraction waste residues, solid-liquid separation of kitchen waste, fruit and vegetable waste organic solid waste, dehydration and reduction of hazardous waste such as paint residue and dry film residue Extraction and dehydration of solid waste such as straw pulp, straw biogas residue and other solid waste.
