De Watering Machine

1) General Introduction

Screw press is mainly used for the fowl manure, Cow Dung Dewatering. This machine can press out about 20% water in the Cow Dung.

2) Structure

Screw press consists of cylinder filtering drum and diameter change screw (The inner diameter increases gradually, the outer diameter is invariant) that form a close compress room. At the end of the screw, pneumatic backpressure disc is added for shaft dewatering and automatic control.

3) Working Principal

After entering the screw press, as the screw shaft turning, the Cow Dung is pushed forward. Because the close room becomes smaller and smaller, and the Cow Dung is pushed by the backpressure disc, filtrate is squeezed out. Cow Dung is discharged between the end of the screw and the pneumatic back pressure disc. Filtrate which goes through the screen flows into the collecting box from the bottom of the envelope.

Shaft dewatering can make dewatering effect consistent inside and outside of the compressed Cow Dung layer. Big compression ratio screw shaft and pneumatic backpressure disc make the Cow Dung highly dried to meet the required consistency for the following stage. The pneumatic backpressure disc can automatically control the discharging pressure, making the dryness of the discharged Dung uniform and steady.

4) Detailed Product Description

This is a good machine for fertilizer. It can separate the organic fertilizer from the desired raw material, fowl manure and others. The machine uses the pump to pull the fowl manure, Cow Dung, etc, into the dewater equipment, the material through the screen and then press by the screw, the rotary speed of the machine can reach 45 RPM, within the press of the screen and high rotary speed, the material will be dewatered by the machine and the water will enter into the pool through screen.
