Plate Frame Mud Press Machine Belt Press For Sludge Dewatering Wastewater

Product Specification

Mud Dewatering Filter Press Wastewater Treatment Plate And Frame Filter Press

Product Description:
Plate and frame filter press is a machine used in chemical dehydration. It has the advantages of large filtration driving force, high solid content of the filter cake, clear filtrate, high solid recovery rate, and low consumption of conditioning drugs. It is widely used in some sewage plants.

Dehydration Process:
The plates and frames are arranged alternately. Both sides of the filter plate are covered with filter cloth. The plates and frames are pressed tightly with a pressing device, that is, a filter press chamber is formed between the plates and frames. There is a small hole in the same position in the middle of the upper end of the plate and frame. After being compressed, it becomes a channel. The sludge pressurized to 0.2~0.4MPa enters the filter press chamber through this channel. The surface of the filter plate is carved with grooves. The lower end There are holes drilled for the filtrate to be discharged. The filtrate is discharged from the filter through the filter cloth and along the grooves and holes under pressure to dehydrate the sludge. The plate and frame filter press can withstand higher sludge specific resistance than the vacuum filter, which can reduce the consumption of conditioner. The moisture content of the mud cake can generally be 75%-80%.

Work Process:
1. Feeding stage: This is the beginning of the work of the plate and frame filter press. The material is transported to the feed port of the plate and frame filter press through a feed pump or pipeline and enters the filter chamber between the filter plates.
2. Filtration stage: After feeding, the plate and frame filter press uses pressure to separate liquid and solid. This stage mainly separates solid particles from liquid through filter cloth.
3. Pressing stage: By applying greater pressure, the solid particles on the surface of the filter cloth are squeezed out and the filtering capacity of the filter cloth is restored.
4. Washing stage: Wash the filter cake by injecting washing water into the filter chamber. The purpose is to remove residual liquid and pollutants in the filter cake and improve the quality of the filter cake.
5. Unloading stage: After the washing is completed, the filter plate in the filter chamber of the plate and frame filter press begins to open, and the filtered cake is discharged from the filter chamber.

Applicable:
Liquid-solid separation in industries such as chemical industry, metallurgy, petroleum, ceramics, food and pharmaceuticals, building materials, coal washing, sand washing and sewage treatment

Feature:
1.Filter press saves power consumption and presses the filter cake twice after filtration. The density of the filter cake increases and the moisture content decreases.
2.Filter press automated design has high work efficiency and the filter press has a wide range of applications.
3.low energy requirement, Reliable, automatic operation,
4.Solid and robust design for demanding operating conditions, Long service life
5.High operating availability, Free access to plate pack, Special design for aggressive media.

6.Durable and easy to use, made of thickened material, long-lasting and sturdy

7.The main beam of the filter press is made of thickened steel. The surface has been treated and has high hardness, which is not afraid of wear and corrosion.

8.The plate and frame filter press adopts humanized design as a whole, and the product filtration operation is stable.
