Description

Technical Field

[0001] The utility model relates to the technical field of filter cloths, in particular to an anti-static dust removal filter cloth. Background Art

[0002] Filter cloth is a filter medium woven from natural or synthetic fibers. It includes metal mesh or filter screen. It is mainly used for air filtration and dust removal, dust collection powder to purify the air and protect the environment in smelters, chemical plants, sugar, dye, medicine, food and other industries.

[0003] In the process of realizing the utility model, the inventors found that the following problems existed in the prior art and have not been solved: the existing anti-static dust filter cloth fixing method is: the flange cloth is located on the lower side of the pressure plate, and then the pressure plate is positioned, thereby indirectly realizing the extrusion limit of the flange cloth. However, if the filter cloth needs to be disassembled for cleaning or replacement in the later stage, the pressure plate must be disassembled and taken out first, and then the filter cloth must be pulled out. This method of positioning the filter cloth is relatively cumbersome and urgently needs to be improved. Therefore, we propose an anti-static dust filter cloth. Utility Model Content

During the use of the anti-static dust removal filter cloth, the limit rod can be passed through the opening to make its top end plug into the limit groove of the pressure plate, and the flange cloth is squeezed through the limit block so that the flange cloth can be detachably assembled and fixed to the bottom of the pressure plate. If the filter bag is cleaned or replaced at a later time, the limit block can be removed separately to pull out the filter cloth. Compared with the existing method of disassembling the pressure plate and then pulling out the filter cloth, the process is simpler and more practical.

The spring can be used to give a force to the semicircular head so that the semicircular head is pressed against the bead groove to achieve the limiting of the limit rod. If it is necessary to remove the limit block, force is applied to pull down the limit rod, and the spring subjected to the force on the semicircular head contracts, so that the limit block can be removed, and reverse force can be applied to realize the reinsertion of the limit rod. The limiting structure facilitates the disassembly and assembly of the limit block, indirectly improves the disassembly and assembly efficiency of the filter cloth, and the use effect is relatively ideal.

[0011] As an optional solution of the technical solution of the present application, an indicator sticker is glued to the front side of the pressure plate with guiding text printed on the indicator sticker. The indicator sticker and the guiding text can inform the operator of the corresponding process, making it convenient for different personnel to disassemble and use it.

When disassembling the sleeved filter cloth, the pinch pieces on both sides can be pinched with both hands respectively to apply force to move the filter cloth up or down, making it easy to disassemble and use.

[0013] As an optional solution of the technical solution of the present application, a groove is provided on the outer side of the filter cloth near the bolt, and the end of the bolt is located in the groove, and the end of the bolt can be received by the groove to prevent the bolt from protruding outward and affecting the disassembly and assembly of the filter cloth.

[0014] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0015] 1. The utility model provides an anti-static dust filter cloth, which is provided with a limit rod, a limit block and an opening. During the use of the anti-static dust filter cloth, the limit rod can pass through the opening to make the top end of the anti-static dust filter cloth plugged into the limit groove of the pressing plate, and the flange cloth can be squeezed through the limit block so that the flange cloth can be detachably assembled and fixed on the bottom of the pressing plate. If the filter bag is cleaned or replaced at a later time, the limit block can be removed separately to pull out the filter cloth. Compared with the existing method of disassembling the pressing plate and then pulling out the filter cloth, the process is simpler and more practical.

[0016] 2. The utility model discloses an anti-static dust removal filter cloth, which is provided with a semicircular head and a spring. The spring can give a force to the semicircular head so that the semicircular head is pressed against the bead groove to limit the position of the limit rod. If the limit block needs to be removed, force is applied to pull down the limit rod, and the semicircular head force spring contracts to realize the removal of the limit block. Reverse force can be applied to realize the reinsertion of the limit rod. The limit structure facilitates the disassembly and assembly of the limit block, thereby indirectly improving the disassembly and assembly efficiency of the filter cloth, and the use effect is more ideal.
