Description
Technical Field
The invention belongs to the field of filtering equipment in a solid-liquid separation process, and relates to an anti-corrosion plate 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, pharmacy, dye, 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 a frame sealing surface of the filter plate, the filter cloth is tightly attached to the filtering surface of the filter plate, a filter chamber is formed by concave parts of two adjacent filter plates, materials enter the filter chamber through the pressure of a feed pump, particles trapped in the filter cloth form a filter cake, and filtrate is discharged from a pipeline through a liquid outlet of the filter plate, so that the purpose of solid-liquid separation is realized; because the filter press has wider application industry, various filter plates and different forms, different filter cloth forms corresponding to different filter plate forms are needed, and the filter cloth forms are also diversified. The angle feeding filter plate is characterized in that the feeding holes are formed in one side of the corners of the filter plate, the feeding hole structure is irregular, and the angle feeding anti-corrosion plate cannot be used for double-sided filtration, and the filter cloth cannot pass through the center material hole to be lapped on the cloth hanging pin on the top surface of the filter plate like the filter plate, so that the filter cloth is not well fixed and frequently falls off; the structure of the feed hole is irregular, the periphery contacted with the sealing surface of the frame is thicker, the feed hole in the chamfer groove is relatively thinner, a straight-tube filter cloth hole is formed, redundant filter cloth is crowded together and is easy to block materials, so that the materials enter a chamber (filter chamber) unsmoothly, and the working efficiency of the filter press is seriously influenced; the filter cloth is hung only by the cloth hanging pin at the top of the filter plate, and is easy to shake left and right to cover the rest triangular holes of the filter plate.
Disclosure of Invention
The invention aims to overcome the defects of the conventional corner feed anticorrosive plate filter cloth, solve the corresponding technical problems, and provide a fixing method of the corner feed anticorrosive plate filter cloth.
The technical scheme adopted for solving the problems in the prior art is as follows: the fixing method of the corner feed anticorrosive plate filter cloth comprises the steps of firstly, changing the shape of a feed hole filter cloth sewing piece, changing the original regular rectangle into a bridge hole type, and reducing the congestion of the filter cloth at a thin feed hole; secondly, making the feeding hole filter cloth sleeve penetrate into the interior of the feeding anti-corrosion pipe, wherein the diameter of the feeding hole filter cloth sleeve is equal to that of the inner wall of the anti-corrosion pipe, and designing annular filter cloth on the periphery of the feeding hole filter cloth sleeve, and connecting the feeding hole filter cloth sleeve and the annular filter cloth into a whole by using a sewing thread; thirdly, cloth hanging pin holes are formed in the periphery of the filter cloth, the sizes of the holes are equal, and the positions of the holes correspond to the cloth hanging pins around the anti-corrosion plate.
Further, the feed hole stitching sheet is cut into bridge holes by the original rectangular cloth, and the rectangular stitching sheet cannot be directly used because of irregular peripheral structures of the feed holes, so that the feed hole stitching sheet is designed into a three-side straight line with a circular arc bridge hole on one side; two symmetrical straight edges are longer, and the other connected straight edge is shorter; the specific method of the feeding hole sleeve is as follows: cutting an arc shape, namely a bridge hole shape, on the right side of the sewing piece by taking the central line as a reference, and sewing two longer straight edges of the sewing piece together by lapping the two longer straight edges with yarns, wherein the sewing piece becomes a feeding hole sleeve; the circular arc of tailorring corresponds the thin feed port periphery in the chamfer inslot, and two longer straight flange correspond the thick feed port periphery of corner hole and sealed face contact, and the width of sewing up the piece has close relation with the girth of feed port, and the width is greater than feed port girth 40 millimeters, and the synthetic feed port sleeve of two longer straight flange lap joints of sewing up the piece of being convenient for, and the length of sewing up the piece then is: the thickness of the anti-corrosion plate, the thickness of the thrust plate and the length of the anti-corrosion pipe protruding out of the thrust plate are combined; then connecting the circular filter cloth with the corner feed holes of the whole piece of filter cloth by using a sewing thread, and sewing the circular filter cloth at one end far away from the corner feed holes again to enable the circular filter cloth and the feed hole sleeve to be connected into a whole, thereby forming an integral corner feed anti-corrosion plate filter cloth; the circular arc circumference of the sewing piece is equal to the circumference of the corner feed Kong Baobian, so that the sewing piece is ensured to be easily connected with the filter cloth around the corner feed hole; the feed hole sleeve external diameter is less than or equal to the feed anti-corrosion pipe internal diameter, the feed hole sleeve penetrates the feed anti-corrosion pipe and is placed in the inside of the anti-corrosion pipe, its length must be greater than the length of feed anti-corrosion pipe, the outside open overlap joint of annular filter cloth of sleeve one end is at the outside extension terminal surface of feed anti-corrosion pipe (annular filter cloth is the horn mouth shape and opens, feed hole sleeve is spread easily when being convenient for the feeding, make the pressure filter put into production smoothly), when two flange are with the bolt-up, just in time press the extension terminal surface of feed anti-corrosion pipe, make the filter cloth compress tightly the outside extension terminal surface of feed anti-corrosion pipe along the area, bolt-up two flanges, thereby play the effect of fastening filter cloth, make filter cloth one end have fixed place, be difficult for droing.
Further, cloth hanging pin holes are formed in the periphery of the filter cloth, the diameters of the holes are equal, the positions of the cloth hanging pin holes correspond to the positions of a plurality of cloth hanging pins at the center lines of the four sides of the anti-corrosion plate, the cloth hanging pin holes are sleeved on the cloth hanging pins, the periphery of the filter cloth is fixed, and the filter cloth is prevented from shaking left and right to shield the corner holes of the anti-corrosion plate.
The fixing method of the corner feeding anticorrosive plate filter cloth has the characteristics of simple structure, novel thought and strong practicability, can meet production requirements by simple thought change without consuming a large amount of material resources, improves production efficiency and increases economic benefits of enterprises.
