Plate and frame filter press

Plate and frame filter

Product introduction

  The plate and frame filter press is a fast and continuous filtering equipment. The motor type uses hydraulic execution and PLC control mode, which improves the reliability, stability and safety of equipment control. The filter area of the plate and frame filter press is several times larger than the general filter area, which is widely used in various suspended solid-liquid filtration and separation fields. The plate and frame filter press has a simple structure, compact equipment, a large filtering area and a small footprint, high operating pressure, low water content in the filter cake, and strong filtration ability for various materials.

Scope of application:

1. Food: beverages, enzymes, yeast, plant protein, brewing, beer, soy milk, white wine, etc.

2. Chemical industry: dyes, pigments, water purifiers, etc.

3. Sewage treatment: brewing sewage, chemical sewage, smelting sewage, electroplating sewage, fur sewage, printing and dyeing sewage, pharmaceutical sewage, environmental sewage, etc.

4. Hospital: antibiotics, calcium phytate, Chinese medicine, plant extracts, saccharifying enzymes, etc.

5. Metallurgy: gold ore, silver ore, iron ore, copper ore, zinc ore, rare earth, etc.

6. Clay: Kaolin, bentonite, activated soil, etc.

Material and structure of equipment

Plate and frame filter press consists of five parts: filter plate, hydraulic system, filter frame, filter plate transmission system and electrical system. The frame mostly adopts high-strength steel structural parts, which is safe and reliable, stable power and durable. The filter plate and filter frame are made of reinforced polypropylene primary membrane compression molding, with relative size and chemical stability, high strength, light weight, acid and alkali resistance, non-toxic and tasteless, and all filter surfaces are anti-corrosive media and food sanitary materials.

Both the filter plate and the filter frame of the plate and frame filter press are pressed by a pressing device, and a handle is provided at the position of the filter plate and the filter frame to support the entire filter chamber structure. The filter cloth installed between the filter plate of the plate and frame filter press and the filter frame can not only perform the filtering work, but also function as a sealing gasket.

Product design

控制,机-- 体化设计。 1. The automatic pull plate filter press adopts PLC control and the machine - electric - hydraulic integrated design.

2. The equipment is made of 304 and 316L high-quality stainless steel materials, which is resistant to corrosion and durable.

3. The number of filter plate layers can be appropriately reduced or increased according to the size of the user's production flow, so that it is suitable for production needs, so the plate and frame filter has the function of one machine for multiple uses.

4. The filter plate adopts a flat thread mesh shape with advanced structure, no deformation, and easy to clean.

Five, plate and frame filter press products

1. The equipment has the advantages of simple structure, convenient maintenance, easy operation and stable and reliable filtration quality.

2. The machine has a large filtering area, a large flow and a large application range.

3. All sealing parts are made of silicone rubber sealing ring, which is resistant to high temperature, non-toxic, non-leakage and good sealing performance.

Working principle

Plate and frame filter press is composed of filter plate and filter frame (plate and frame type) or filter plate array (vane type) to form the filter chamber. Under the action of the feed pump, the suspension (liquid material) is pressed into each filter. In the chamber, the filter medium (commonly used filter cloth, filter paper, filter membrane, etc.) is used to separate the solid from the liquid and gradually form a filter cake; the liquid is discharged out of the machine through the water outlet hole on the plate frame. As the degree of filtration progresses, filter cake filtration begins, the thickness of the mud cake gradually increases, and the longer the filtration resistance plus the filtration time, the higher the separation efficiency. The specially designed filter cloth can not trap particles with a particle size smaller than 1 um.

The drainage of the plate and frame filter press can be divided into two types: open flow and under flow. The filtrate is directly exposed to the outside of the machine through the water outlet holes on both sides of the plate frame. The advantage of open flow is that the liquid output of each filter plate can be observed, and the problem can be directly found through the transparency of the filtrate. The form of underflow holes discharged from the rear roof is called underflow.

When washing is required, close the water outlet valve of the rinsing plate and open the water outlet valve of the pressure plate at the same time. Under a certain pressure, the rinsing water will pass through the filter cloth, filter cake in the water tank of the rinsing plate, and reach the pressure plate water tank through the filter cloth Flow into the drain valve and out of the machine. In this way, after the circular rinsing, the filtrate remaining in the filter cake is sufficiently taken out of the machine by the rinsing water, and the rinsing effect is achieved.
