Screw press machine
Scope of application of screw dehydrator:
       The screw dehydrator is suitable for continuous operation of various high-humidity materials, such as: biomass, meal waste and domestic waste, vegetable, fruit and vegetable processing, peel residue, crop straw, biogas residue, plant straw, livestock and poultry Manure, paper pulp, wood pulp, bagasse, medicine residue, distillers grains, fruits and vegetables, wood residue, traditional Chinese medicine residue, plastic waste residue, paint residue, potato residue, starch, xylitol, straw pulp, cotton pulp, leaf residue, seaweed, Bamboo pulp, seaweed, water hyacinth, corn cob, furfural residue, rice husk, cottonseed husk, polysaccharide, livestock and poultry extrusion degreasing, plant rhizome, papermaking tailings, waste paper pulp.
       The screw dehydrator has a reasonable structure; stable and reliable use; high solid-liquid separation rate; low-concentration feed and high-concentration discharge; low loss, high extraction rate, low operating cost; easy installation, small footprint, convenient operation, and maintenance Small and reliable. The material enters the new type of continuous dehydrator from the feed port. The design change of the lead of the spiral guide roller causes the pressure of the material to gradually increase during the movement, from the feed screw section to the compression section of the low pressure zone and then to the compression section of the high pressure zone. The solid-liquid separation of the material is realized to a large extent, and the material liquid is separated through the stainless steel separation filter screen. The separated liquid is discharged from the bottom of the unit and the liquid discharge port inside the guide roller, and the squeezed material is continuously discharged from the discharge port. discharge.
        The screw dehydrator is mainly composed of a body support, a feed port, a screw rotor, a pressing screw, a dehydration system, a high-strength filter screen drum, an anti-clogging stainless steel filter screen, an automatic cylinder pressure plate resistance device, a discharge port, a motor reducer, and a water collection tank , Protective cover and other components.

 The screw press is the company’s screw continuous press equipment. The internal screw adopts a step-by-step extrusion and continuous advancement type, which has fast pressing speed, high dehydration rate and large output.
Because the variable diameter press relies on the squeezing screen to squeeze the material, the screw is very easy to wear. The machine adopts the EF plus compression principle and does not squeeze the screen, thereby effectively avoiding the wear of the screw. Even if it is adjusted to wear, it will not affect The use of the press,
The machine adopts different pitch and shaft diameter design methods for different materials, and the length, radian and propulsion methods of different feeding screw, conveying low-pressure zone screw, and high-pressure zone pressing section are different. It is an indispensable equipment for materials in various industries to be pressed and squeezed to dry, which can greatly reduce the energy consumption of the dryer! For different materials, the dryness and moisture content after dehydration is about 45-70%.

Technical characteristics of double screw press:

1. Spiral 304 stainless steel casting, wear-resistant, made of 304 screen, durable. The screen can be designed as a two-half screen according to the needs, which is easy to disassemble and clean. The screen aperture is designed according to the material characteristics, and the dehydration efficiency is high.

2. There is an inner net about 50cm in length at the end of the pressing screw, the outer net flows out, and the inner net flows in, so the dehydration efficiency is high.

3. Adjust the back pressure tail cone that controls the dry and wet degree of the material. According to the pressure required by the material during pressing, its control methods include hydraulic control (0.1-26Mpa), spring control (1-6Mpa), handwheel control, Pneumatic piston control type (0-0.8Mpa) and other four kinds of controls, flexible selection.

4. The lower part of the feeding box and the spiral are designed with special angles, so that the materials are not stacked and overhead in the feeding box.

5. With a secondary reduction gearbox, the motor power is small and the output torque is large, energy saving and environmental protection.
