What Can You Know about Small Screw Press Dewatering Equipment?

Scale Animal Husbandry

Generally speaking, small screw press dewatering equipment is known as animal manure dewatering machine or solid-liquid separator. Also, it is primarily of use in dehydration pretreatment for animal manure in livestock farming or for the digestate in modern agriculture and animal husbandry.

Material of Screw Press Dewatering Machine

In addition, this dewatering machine can do solid-liquid separation of high-concentration organic waste or wastewater, e.g. livestock and poultry dung like chicken, cow, horse, sheep, pig manure, wine lees, kitchen waste, fruits and vegetables, Chinese medicine residues, starch pulp, bagasses, paper pulp, river mud, biogas residue, etc.

Inclined Dewatering Machine for solid-liquid Seperation

What’s more, the small solid-liquid separator is mostly of use for waste with water content less than 65%, whereas manure with moisture greater than 75% require the inclined dewatering machine. Moreover, the water content of the solid materials after separation is in the range of 30-40% or less.

How Does A Small Screw Press Dewatering Machine Work?

What Is This Small Dewatering Equipment composition?

Screw press solid-liquid separator mainly consists of the main body, non-clogging pump, pipeline, electrical control cabinet and other devices. Meanwhile, the main body contains the motor, the reducer, the screen mesh, the screw press, the feeding port, the discharging port, the cleaning observation port and the water outlet.

What Is The Work Principle of Screw Press Dewatering Machine?

1 Firstly, the non-clogging pump supporting the dewatering machine elevates and sends the unfermented feces to the dewatering machine. At this time, through the electric power, the screw press pushes the manure gradually to the front of the machine. At the same time, it constantly raises the pressure of the front edge.

2 The rotating screw pushes materials forward to extrusion section. Under the compression of two forces, the pressure of the pressure spring and the thrust of the screw, this equipment extrudes materials’ moisture and then discharges by the screen mesh. In the meantime, it accelerates to drop materials under the action of the motor.

3 The work of the screw press is continuous. When the material is generally pumped into the body, the pressure of the front edge is increasing. Besides, when it reaches a certain degree, the discharge port will be opened and extruded materials out. Thus, you can achieve the purpose of solid-liquid separation.

Another Small Dewatering MachineRotary Drum Solid-liquid Separator

After years of research, our company has developed another dehydrator, which improves properly the details of the original dewatering machine. Thus, rotary drum solid-liquid separator is improved based on the shortcomings of traditional dewatering machines. Moreover, it is suitable for disposing low-concentration, low solid content and slight materials. Besides, it enhances the treatment efficiency and solves the problems of high solid content in drainage.

When Can You Use Drum Small Dewatering Machine?

For one thing, drum dewatering machine can deal with raw materials with high moisture, such as manure by rinsing or water submerging, duck manure, biogas residue and biogas slurry.

  • Because the particles in water-soaked feces are tiny and contain a lot of water. Therefore, the standard solid-liquid separation system cannot filter entirely, and then solid fecal particles circulate back into the storage container (septic tank) with liquid. The solid-liquid separation machinery works ineffectively for a long time, wasting energy.

For another thing, it is capable of separating the tiny suspended substances in the liquid and organic residue to the maximum extent, like phytoplankton or zooplankton, so as to achieve the purpose of recycle of useful matter.

Manure Cleaning by Rinsing Or Water Submerging

How Does A Small Drum Dewatering Machine Work?

This machine applies a secondary separation process.

  • Firstly, you can thoroughly mix the feces in the storage tank through the mixing system to achieve the more uniform consistency.
  • Then, the transfer pump sends materials to the drum. Through the filtration screen, the sewage enters into a reservoir or sewage treatment system.
  • And, the solid substances enters the screw press by the spiral device. This way can reduce material moisture at a certain degree.

Drum dewatering machine adopts the unique split design — the fecal filtration and solid-liquid separation operate independently. Meanwhile, you can adjust according to the actural situation. And there are few operational faults, simple maintenance and easy operation.

What Are The Features of Rotary Drum Dewatering Machine?

  • It has better treatment effect for dealing with raw materials after fermentation with low solid content, tiny fibers and long soaking time.

  • The liquid has low solid content after the screen mesh, which is more conducive to later sewage treatment. And we can design different screen mesh density according to customer requirements. This screen can filter more than 300 microns of fecal particles with remarkable filtration effect and convenient cleaning.

  • After solid-liquid separation, the materials enters the screw press dewatering machine with high concentration, achieving higher processing efficiency.

  • Our equipment is resistant to wear and corrosion.
