1250mm Fully Automatic Membrane Filter Press-Yuwei Filtration Equipment Co., Ltd.

Description

The fully automatic membrane filter press is composed of a filter chamber arranged by membrane plates and box filter plates. Under the pressure of the feeding pump, the materials are input into the filter chamber, and the solids and liquids in the materials are separated through the filter medium (filter cloth). When the solids in the materials form a cake, water (or air) is injected into the membrane plated to fully squeeze the solids in the filter chamber.
Fully automatic programmed membrane filter press can reduce water content. Especially for the filtration of viscous materials and users with high requirements for moisture content, this machine has its unique characteristics. The filter plate is molded from reinforced polypropylene. The diaphragm and polypropylene plate are inlaid together, which is firm, reliable, not easy to fall off, and has a long service life. It is equipped with a variety of safety devices to ensure the safety of the operator and the normal operation of the filter press.

Advantages

There are adopted Low pressure filtration and high pressure pressing, which are more efficient than traditional filter presses, greatly shortening the entire filtering cycle.
The independently developed high-strength PP filter plate is used, and the compression pressure can reach 22MPA.
Save the consumption of operating power. In the later stage of filtration, the flow is small and the pressure is high.
The working process of membrane pressing consumes very short time, saving power consumption.
Increase the density of cake and reduce the water content of cake. The membrane squeezes the filtered filter cake for the second time, so that the internal structure of the filter cake is rearranged and the density is increased, thus replacing part of the water, so that the water content is greatly reduced, the drying cost is saved, and the yield is increased.
It has strong corrosion resistance and is basically applicable to all solid-liquid separation operations.
It can be configured with PLC and human-computer interface control, and the operation procedure can be adjusted according to the on-site working conditions.
Membrane filter plate has good toughness, anti-aging and sealing performance to achieve the purpose of aseptic filtration. The user can also adjust the number of filter plates according to the size of the filter volume to meet the production needs.

High pressure dewatering technology is applied in the sludge dewatering industry. The water content of filter cake is reduced to meet the landfill and incineration standards (the water content in different industries varies). Compared with traditional dewatering equipment, the water content of filter cake is greatly reduced; The whole machine can realize fully automatic operation, and is equipped with online filter cloth flushing system and electric control valve instrument to realize unattended operation.

Product structure and working principle

The main difference between the membrane filter press and the ordinary chamber filter press that two elastic membranes are installed on both sides of the membrane plate. During operation, high-pressure fluid (or gas) medium can be injected into the diaphragm. When the filter cake fills the whole filter chamber, the equipment stops filtering, and then fills the filter plate with pressure medium (water or gas). At this time, the whole diaphragm will bulge, making the pressure act on the filter cake. With the increasing pressure, the liquid in the filter cake that can pass through the filter cloth will be pressed out, and the secondary dehydration of the filter cake will be realized, making the water content of the filter cake lower.
The materials are pumped into each sealed filter chamber of the filter. Under the action of working pressure, the filtrate passes through the filter membrane or other filter materials and is discharged through the liquid outlet. The filter residue is left in the frame to form a filter cake, so as to achieve solid-liquid separation.

Application

Membrane filter press is widely used in petroleum, chemical industry, pharmacy, sugar making, food, coal washing, grease, printing and dyeing, brewing, ceramics, mining metallurgy, sewage treatment and other fields.

Frequently Asked Questions

What is the primary difference between this membrane filter press and a standard chamber filter press?

The key difference is the addition of elastic membranes on both sides of the filter plates. In a standard press, filtration stops once the chamber is full. With a membrane filter press, after the initial filtration is complete, a high-pressure medium (water or gas) is injected into the diaphragm. This causes the membrane to inflate and physically squeeze the filter cake, performing a secondary dehydration process that significantly lowers the final moisture content.

What are the pressure specifications and capabilities of this equipment?

This model is built for low-pressure filtration combined with high-pressure pressing. The standard feeding pressure ranges from 1.2 to 2.5 MPa. To achieve optimal secondary squeezing, the hydraulic system operates at 18 MPa, and the independently developed, high-strength reinforced polypropylene (PP) filter plates can withstand compression pressures of up to 22 MPa.

Can this filter press safely handle highly corrosive materials?

Yes, it is designed with strong corrosion resistance to handle a variety of harsh working conditions. The filter plates themselves are molded from durable reinforced polypropylene. Furthermore, the machine's structural skeleton can be customized depending on your needs; options include standard paint, stainless steel, or a specialized PE (polyethylene) coating specifically designed for operations involving highly corrosive slurries.

How automated is the operation of the 1250mm filter press?

The machine is fully automatic and designed for unattended operation. It is equipped with a Programmable Logic Controller (PLC) and a human-computer interface, allowing you to easily adjust operation procedures based on real-time site conditions. It features automatic plate shifting for discharging the filter cake and is equipped with an online filter cloth flushing system and electric control valves to minimize manual labor.

Which industries benefit the most from using this high-pressure membrane filter press?

Because it excels at reducing the water content of filter cakes, it is incredibly valuable in the sludge dewatering industry, helping facilities meet strict landfill and incineration moisture standards. It is also highly effective for processing viscous materials and is widely utilized in mining, metallurgy, coal washing, petroleum, chemical manufacturing, pharmaceuticals, ceramics, printing and dyeing, and the food and beverage industry (such as brewing and sugar making).
