Description

Technical Field

[0001] This utility model relates to the field of cylindrical filter technology, and more specifically, to a filter cloth installation device for a cylindrical filter. Background Technology

[0002] In the mineral refining process, filtration machines are needed to remove water from the slurry. Currently, mining filters are mainly divided into three types: cylindrical filters, disc filters, and tilting filters. Compared to the other two types, cylindrical filters have a relatively simple structure and a lower failure rate. The cylinder of a cylindrical filter is a large, hollow cylinder made of iron or wood, with many small grooves on its surface. The surface is covered with filter cloth. As the cylindrical filter is used, the filter cloth will wear down and needs to be replaced.

[0003] A search revealed that utility model patent CN210278437U discloses a filter cloth installation device for a cylindrical filter, comprising a low-pressure fluid conveying steel pipe, a fixing sleeve, a fixing rod, and an installation component. The fixing sleeve is fixedly installed at both ends of the low-pressure fluid conveying steel pipe, the fixing rod is fixedly installed on the outer wall of the fixing sleeve, and the installation component is fixedly installed on the front wall of the fixing rod. The front wall of the fixing rod has an installation hole in the middle, and the outer wall of the installation component has a connecting piece around its circumference. This filter cloth installation device for a cylindrical filter has a reasonable structural design. The added low-pressure fluid conveying steel pipe, in conjunction with the fixing sleeve and fixing rod, secures the filter cloth, preventing it from falling off and facilitating its disassembly and installation. This effectively avoids downtime caused by the hemp rope coming loose. However, the aforementioned patent has the following shortcomings: it is inconvenient to temporarily fix the filter cloth during the wrapping process, it is inconvenient for one person to operate, and there are seams at both ends during the wrapping process, making it difficult to fix the seams. Therefore, we propose a filter cloth installation device for a cylindrical filter. Utility Model Content
