Description
Technical Field
The invention relates to the field of filter presses of filter equipment, in particular to filter cloth with rubber and lining cloth arranged on the sealing surface in a crossed manner and a preparation method thereof.
Background
The filter cloth is a filter medium arranged on a filter plate of the filter press, the filter cloth is arranged on two sides of the filter plate, the filter cloth is tightly pressed by the frame of the filter plate when in work, a closed filter chamber is formed between two adjacent filter cloths, materials enter the filter chamber through the pressure of a feeding pump, the filter cloth intercepts particles in the materials, a filter cake is formed in the filter chamber, and filtrate is discharged from a pipeline through a filter plate liquid outlet hole, so that the aim of solid-liquid separation is fulfilled; the filter press has wide application industry, needs various filter cloth types, has thin filter cloth and is not convenient for compressing and sealing, or has other special requirements, needs to increase the thickness of two adjacent filter cloth and is convenient for compressing and sealing.
Two common preparation methods are available, one is to sew a lining cloth on the filter cloth, and the shape of the lining cloth corresponds to the sealing surface; the other is that rubber is covered on the filter cloth according to the shape of a sealing surface. The two existing preparation methods have respective problems, the lining cloth is sewn on the filter cloth, the filter cloth and the lining cloth are generally too thin and are easy to wrinkle, a gap between the filter cloth and the lining cloth can generate slight leakage, and the sewing lines of the filter cloth and the lining cloth can be broken through material washing; rubber is covered on the filter plate, and professional equipment is needed for rubber hot melting, so that the preparation difficulty is high, the production period is long, and the price is higher.
Disclosure of Invention
The invention aims to solve the defects in the background technology, and provides the filter cloth with the sealing surface crossed with glue and lining cloth and the preparation method thereof.
The filter cloth is characterized in that rubber and lining cloth are arranged on sealing surfaces on two sides of the filter cloth in a crossed mode, lining cloth is arranged on the rubber on one side, the size of the lining cloth is the same as that of the sealing surfaces, material placing holes are formed in the sealing surface area of the filter cloth, and holes corresponding to the lining cloth are formed in the sealing surface area of the filter cloth; arranging a suture line along the inner ring and the outer ring of the lining cloth respectively, arranging a suture line outside the material hole in the sealing surface area, and enabling the suture line to penetrate through the filter cloth and the lining cloth to suture the filter cloth and the lining cloth; the rubber is arranged on the outer side of the lining cloth and covers the suture line, so that the suture line is not easy to break.
Preferably, according to requirements, glue is arranged on sealing surfaces on two sides of the filter cloth, and lining cloth is respectively arranged on the glue on the two sides; the size of the lining cloth is the same as that of the sealing surface, and material placing holes are formed in the area of the sealing surface of the filter cloth, and corresponding holes are formed in the lining cloth; arranging a suture line along the inner ring and the outer ring of the lining cloth respectively, arranging a suture line outside the material hole in the sealing surface area, and enabling the suture line to penetrate through the filter cloth and the lining cloth to suture the filter cloth and the lining cloth; the outer sides of the two lining cloths are provided with glue which covers the suture line, so that the suture line is not easy to break.
The invention relates to a filter cloth with rubber and lining cloth arranged on a sealing surface in a crossed manner and a preparation method thereof. According to the invention, the thickness of the filter cloth is increased, and the adjacent filter cloth is tightly attached without a gap, so that material leakage is effectively prevented; the toughness of the filter cloth is improved, the suture line is protected, the filter cloth is more durable, the preparation method is simple, and the production cost is low.
