Description

Filter press filter plate embedded filter cloth filter plate sealing rope ring and manufacturing method

technical field

The invention relates to a filter cloth filter plate sealing rope embedded in a filter cloth filter plate of a filter press using a cotton rope ring instead of a rubber O-shaped sealing ring as a filter cloth fixing material and a manufacturing method, belonging to the field of filter cloth fixing sealing ring manufacturing.

Background technique

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 filter cloth assembly is grooved, and the filter cloth assembly is embedded in the ring-shaped filter cloth embedding groove around the filter cloth. Its disadvantages: first, rubber O-rings are used as the fixing material of the filter cloth, which has great environmental pollution, high energy consumption, and is not easy to recycle; second, the disassembly speed is slow, labor-intensive and time-consuming.

Contents of the invention

Design purpose: To avoid the defects in the background technology, to design a filter press filter plate embedded filter cloth filter plate sealing rope and its production method, which use cotton rope ring instead of rubber O-shaped sealing ring as the filter cloth fixing material.

Design scheme: in order to realize the above-mentioned purpose of the invention. In the structural design of the present invention, the design that the filter cloth adopts the sealing cotton rope ring to replace the rubber O-shaped sealing ring is the main technical feature of the present invention. The purpose of this design is: first, because the raw material of cotton rope is mainly cotton, which is a renewable natural crop, it can be quickly and naturally degraded after use, and will not pollute the environment; second, because of the small density of cotton rope, it can be used in large It can be used under most acids, alkalis, and organic solvents, and it can also be used in a large temperature range, so it has strong applicability; third, cotton rope has the characteristics of natural elasticity and moisture expansion, so the embedded filter made of cotton rope When the cloth is installed and disassembled, it not only has good sealing and fixation, but also is more convenient and quick to install and disassemble than the rubber O-ring.

Technical solution 1: A filter plate of a filter press is embedded with a filter cloth filter plate sealing rope ring, and the filter cloth is embedded into a sealing groove in the filter plate through a sealing cotton rope ring to fix and seal the filter cloth.

Technical solution 2: A method for making the sealing ring of the filter cloth filter plate, a. Long cotton rope, generally showing burrs at both ends; b. Wrapping 2~3 layers of membrane material on one end of the cotton rope, the tightness is appropriate, and then cutting with a special tool to cut off the excess wool to form a neat end of the cotton rope; c. Make a mark at the required length, and also wind 2~3 layers of film material here, the tightness is qualified, and then use a special cutting tool to cut off the excess wool at the marked place, 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 hot-melt adhesive. Process to form a looped cotton rope.

Technical solution 3: A matching method between the sealing rope and the filter cloth, using cotton rope to sew the embedded filter cloth cover or piece, the joint of the cotton rope should be sewn first, and should be sewn on the straight edge of the filter cloth, The rest of the sewing methods are the same as the embedded filter cloth fixed by ordinary O-rings.

Compared with the background technology, the present invention has the following advantages: one is good sealing and fixing performance; the other is that it can be used under most acids, alkalis and organic solvents, and it can also be used in a relatively large temperature range; the third is the manufacturing cost Low, easy to install and disassemble quickly, the disassembled objects are easy to disperse, and have no pollution to the environment.

Detailed ways

Embodiment 1: with reference to accompanying drawing 1 and 2. A filter plate of a filter press is embedded with a filter cloth filter plate sealing rope, which is characterized in that: the filter cloth 2 is inserted into the sealing groove in the filter plate through the sealing cotton rope 1 and the filter cloth 2 is fixed and sealed.

Embodiment 2: with reference to accompanying drawing 3. On the basis of embodiment 1, a kind of manufacture method of filter cloth filter plate seal rope ring, a. select the long cotton rope 1 of suitable diameter, color, hardness and weaving method for use, generally present burrs at two ends; b. Wrap 2~3 layers of film material 2 at one end, with appropriate tightness, and then use a special cutting tool to cut off the excess wool to form a neat cotton rope end 3; c. Make a mark at the required length, and wrap 2~3 layers of film material here as well 4. The tightness is qualified, and then use a special cutting tool to cut off the excess wool at the marked place to form a neat cotton rope end 5; d. Get the cotton rope section, align the two ends tightly, and wrap or wrap the two ends with the film material 6 The film material 6 can be heat-shrinkable material or hot-melt adhesive, so that the loop-shaped cotton rope 7 can be formed through heat-shrinking or gluing treatment. Hot-melt materials or hot-melt adhesives are all prior art, and will not be described here.

Embodiment 3: On the basis of Examples 1 and 2, a method for matching the sealing rope and filter cloth, using cotton rope to sew the embedded filter cloth cover or piece, the joint of cotton rope should be sewn first, And it should be sewn on the straight side of the filter cloth, and the other sewing methods are the same as the embedded filter cloth fixed by ordinary O-rings.
