Abstract
The utility model discloses an integral lining filter cloth for a washing filter press, which mainly comprises lining cloth, filter cloth and a washing filter plate, wherein the integral lining cloth is cut by a laser cutting machine according to the size input program of a filter plate frame, and rectangular lining cloth is cut on the inner side of a washing liquid outlet hole to protect the filter cloth around the washing hole from being damaged by the impact of washing liquid; the integral lining filter cloth has the characteristics of convenience in operation and high practicability, the production efficiency of enterprises is improved, and the economic benefit of the enterprises is increased.
Description
Technical Field
The utility model belongs to the field of filtering equipment (fluid machinery) in the solid-liquid separation process, and relates to filter cloth of a filter press.
Background
The filter press is a universal solid-liquid separation device and is widely applied to the industries of chemical industry, metallurgy, pharmacy, dye, food, brewing, ceramics and environmental protection. 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, particles in the filter cloth are intercepted to form a filter cake, and filtrate is discharged from a pipeline through a filter plate liquid outlet hole, so that the aim of solid-liquid separation is fulfilled; because the filter press has a wide application industry, a variety of required filter cloths are available, the filter cloths have different thicknesses and compactness due to different varieties, and some filter cloths are thin and smooth in surface and are not beneficial to the compression sealing between the filter plates, so that lining cloth needs to be sewn on the filter cloths to increase the thickness of the filter cloths and the friction force of the frames of the filter plates and be beneficial to the compression sealing between the filter plates.
The existing filter cloth and lining cloth need to be spliced by a plurality of pieces of lining cloth, specifically, triangular and isosceles trapezoid lining cloth are spliced and sewn to form a whole piece of lining cloth and then the whole piece of lining cloth is bonded on a sealing surface of a frame of a filter plate, the whole process is complicated, the working hours are consumed, and the production efficiency is extremely low; when the washing filter press is used, the high-pressure washing liquid is discharged outwards to continuously impact the filter cloth, so that the filter cloth at the washing hole is frequently damaged, troubles are brought to normal operation of the filter press, and the production benefits of enterprises are influenced.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome the defects of the existing filter cloth lining cloth, solve the corresponding technical problems and provide an integral lining filter cloth used on a washing filter press.
The technical scheme adopted by the utility model for solving the problems in the prior art is as follows: an integral lining filter cloth used on a washing filter press is formed by sewing lining cloth and the filter cloth, wherein the lining cloth is cut by a laser cutting machine according to the size input program of a filter plate frame; the rectangular lining cloth is added at the washing liquid outlet, the size of the lining cloth is determined according to the arrangement length of the liquid outlet holes of the filter plate, the length of the rectangular lining cloth is larger than the arrangement length of the liquid outlet holes, and the width is about 60mm generally.
Furthermore, the shape of the lining cloth is square and annular, the size of the square is determined by the external dimension of the filter plate, the size of the frame of the filter plate determines the annular width of the lining cloth, and because the washing hole is frequently damaged, the rectangular lining cloth is additionally arranged on the inner side of the washing hole of the lining cloth, is positioned at the corner of the triangular sealing area and corresponds to the small washing liquid outlet hole of the filter plate.
Furthermore, the lining cloth is designed into a structure which is symmetrical to the horizontal axis and the longitudinal axis, and for the washing filter plate, the filter cloth is not needed to be distinguished, and the filter cloth can be directly installed (because the washing plate is divided into a left washing plate and a right washing plate, the rectangular lining cloth needs to correspond to the small washing holes of the plates), so that the time for sorting the filter cloth is shortened; two mutually-adhered stickers are sewn around each piece of filter cloth, the two stickers are consistent in size and specification, are mutually adhered and overlapped on the side face of the filter plate, fix the filter cloth, avoid small holes at the periphery of the filter cloth and tear the filter cloth.
The integral lining filter cloth used on the washing filter press has the advantages of convenient operation and strong practicability, can meet the production requirement on the basis of not consuming a large amount of manpower and material resources, improves the production efficiency and increases the economic benefit of enterprises.

Detailed Description
The technical solutions in the embodiments of the present invention are described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some preferred embodiments of the present invention, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present invention without making any creative effort, shall fall within the protection scope of the present invention.
Examples
An integral lining filter cloth used in a washing filter press is formed by cutting a laser cutting machine according to the size of a filter plate, each size corresponds to the filter plate, and the centers of two pieces of filter cloth are sewed to form a whole; the filter cloth passes through a central material hole (a feeding hole) of the filter plate, two filter cloths are respectively tiled on two sides of the filter plate, adhesive strips 2 on the periphery of each filter cloth are mutually adhered, and the filter cloth 3 is fixed on the filter plate to form a filter medium.
The whole piece of lining cloth 1 is sewn on one surface of the filter cloth 3 through sewing threads 6, the adhesive strips 2 are also sewn on the periphery of the filter cloth 3 through the sewing threads, and the two adhesive strips are mutually adhered in pairs for fixing the filter cloth 3; the washing holes 4 of the lining cloth correspond to the washing holes 4 of the filter plate, and the sizes are equal; the rectangular lining cloth 7 is positioned at the inner side of the washing holes 4, and the length of the rectangular lining cloth is slightly larger than the length of the arranged small liquid outlet holes; the feed hole 5 is positioned in the center of the filter plate, the material enters each filter chamber through the central material hole, and the filter cloth 3 intercepts particles therein to form a filter cake; the left washing plate 8 and the right washing plate 9 are mutually matched for use, and form a washing type filter press together with the frame, the hydraulic system and the electric control system.
