Embodiment 1

[0011] Embodiment 1: with reference to attached figure 1 and 2 . A special sealing ring for an embedded filter cloth filter plate, the sealing ring adopts a cotton rope ring 1, and the two ends of the cotton rope ring 1 have membrane material sleeves 2 and are relatively connected to form a cotton rope sealing ring. The film material cover 2 is hot melt adhesive.

Embodiment 2

[0012] Embodiment 2: with reference to attached image 3 . On the basis of embodiment 1, a kind of manufacture method of filter cloth filter plate sealing rope ring, a. select the long cotton rope of suitable diameter, color, hardness and weaving method for use, and long cotton rope two ends generally present burrs; b. Wrap 2~3 layers of film material at one end of the long cotton rope, cut off the excess wool to form a neat end of the cotton rope; c. Make a mark on the long cotton rope of the required length, and wrap 2~3 layers of film material here, and then use The cutting tool cuts off the excess wool at the marked place to form a neat cotton rope end; d. Take the cotton rope section, align the two ends tightly, and wrap or cover the two ends with a film material. The film material can be heat-shrinkable material or heat-shrinkable Melt glue, in this way and form a loop-shaped cotton rope through heat shrinkage or glue processing.

Abstract

The invention relates to a special sealing ring for filter plates with embedded filter cloth and a method for manufacturing the special sealing ring. A cotton rope loop of the special sealing ring replaces a rubber O-shaped sealing ring to be used as a filter cloth fixing material, a sealing ring is made of the filter cotton rope loop, and film material sleeves are arranged at two ends of the cotton rope loop and are oppositely connected with each other, so that the sealing ring with a cotton rope can be formed. The special sealing ring and the method have the advantages that the special sealing ring is good in sealing fixing performance; the special sealing ring not only can be used under the conditions of most acid, alkali and organic solvents, but also can be used within wide temperature ranges and accordingly is extremely high in adaptability; the special sealing ring is low in manufacturing cost, convenient to quickly mount and detach and free of environmental pollution, and detached materials of the special sealing ring are easy to scatter.

Description

technical field [0001] The invention relates to a special sealing ring for an embedded filter cloth filter plate using a cotton rope ring instead of a rubber O-shaped sealing ring as a filter cloth fixing material and a manufacturing method thereof, belonging to the field of manufacturing a filter cloth fixing sealing ring. Background technique [0002] All the prior patents of this application, CN201108768Y, are titled "Middle Feed Embedded Filter Cloth Filter Plate". There are liquid outlet holes at the four corners of the filter plate, and there are fluid passages between the liquid outlet hole and the side of the filter plate cavity. The characteristics are: filter plate There is a feed through hole in the center, and there is an annular sealing groove around the sealing joint surface of the filter plate. The O-shaped rubber sealing ring is located in the annular sealing groove, and the filter plate located inside the annular sealing groove has an annular embedded The fi...
