How does the screw dewatering press work?

1: The screw dewatering press is not afraid of wear, and the outlet water is smooth. The purpose of extruding separation is achieved by the effective cooperation of the screw and the screen;

2: It can effectively solve the problem of screen blockage. Its core technology is the cooperation between the screw and the screen to realize the self-cleaning function of the screen, that is, to achieve interaction with the screw through special devices to mix materials. The first is to avoid the material shaft, and the second is that the material particles rub off the screen plug during the spiral forward process;

3: The control of equipment tail cone is different from the common spring, hydraulic pressure, hand wheel, etc. in the market. The pneumatic device with extremely low maintenance cost is used to effectively realize the "back pressure" control of material extrusion through specific design. That is, after a certain extrusion pressure is set, the device automatically controls the extrusion pressure of materials to avoid dry and wet slag. The extrusion separator adopts the superposition compression principle, which is especially suitable for assembly line operation and avoids the shortcomings of centralized processing of ordinary extruders;

4: The feed box is designed at a special angle to effectively prevent "bridging" of some viscous materials. Although this phenomenon is a small detail, once it occurs on the production site, the "scaffolding" is not, which will lead to shutdown without feeding, which is troublesome, so details determine success or failure;

5: The screen of spiral dehydration equipment is two half screens. For food waste dehydration, food processing, fruit and vegetable processing and other industries, it is easy to disassemble and clean thoroughly.

Available fields of screw dewatering presss:

The screw dewatering press is mainly used for kitchen waste, vegetables and fruits, residues, raw pulp paper, cassava starch residue, slaughtered straw pulp, maltitol, bean curd residue, binding, etc., To obtain and separate high concentration slag liquid. The materials enter the new spiral extruder from the feeding port. According to the dividing circle diameter of the spiral guide roller, the width becomes smaller, and the guide roller blade groove becomes thinner from the depth. Therefore, the working pressure of materials in the fitness exercise gradually increases. The material liquid is separated according to the stainless steel plate separation net. The separated liquid is discharged from the bottom of the generator set and the outlet inside the guide roller, and the extruded and dried materials are discharged from the feed inlet. The key of this equipment is motor shaft, spiral guide roller, dehydration system software (separation spherical grid, stainless steel plate separation net), reducer, motor, etc.

The key prefabricated component of the screw dewatering press is the screw. Its bottom diameter increases slowly along the direction of slag inlet and outlet, and the tooth spacing decreases slowly. When the material is pushed by the screw, the material is extruded due to the small volume of the screw cavity. The rotation direction of the spiral spindle bearing is from the feed bin to the slag trough. In order to add the slag to the feed bin clockwise, it is forced by the screw. The juice is injected into the bottom juicer according to the filter screen, the waste is discharged according to the gap between the screw and the tapered part of the pressure transformer, and the pressure transformer moves radially to adjust the gap size. When the handle bearing is loaded clockwise, the pressure transformer head is left, and the clearance becomes smaller, on the contrary, the clearance increases.
