Description

Technical Field

[0001] The utility model relates to the technical field of filters, in particular to a novel filter cloth air-blowing unloading device. Background Art

[0002] Currently, filters are an indispensable device in pipelines conveying media, typically installed at the inlet of other equipment such as pressure reducing valves, pressure relief valves, and water level control valves. Filters are typically cylindrical. After the water to be treated passes through the filter cartridge at the filter conduit mounting port, impurities are blocked. When cleaning is required, the removable filter cartridge must be removed, treated, and reinstalled. If the filter is not securely fixed, leakage can easily occur between the conduit and the filter at both ends, affecting the filter's normal operation. Therefore, the stability of the filter's mounting is extremely important.

[0003] However, there are still some problems when using the existing filter:

[0004] The existing filter needs to be opened after filtering to take out the filtered material, which is very troublesome and greatly reduces work efficiency. Utility Model Content

[0008] Preferably, a through hole is provided on the top inner wall of the rotating groove, and a vertical rod is slidably installed in the through hole, with one end of the vertical rod extending into the rotating groove and the other end of the vertical rod extending out of the rotating groove.

[0009] Preferably, a rotating shaft is installed in the rotating groove, one end of a thin rope is wound around the rotating shaft, and the other end of the thin rope is in contact with one side of the gear lever.

[0010] Preferably, a rotating wheel is fixedly mounted on one end of the rotating shaft, and a plurality of rotating blocks are evenly and annularly fixedly mounted around the rotating wheel. A plurality of grooves are evenly spaced on one side of the vertical rod close to the rotating wheel, and the grooves are adapted to the rotating blocks.

[0011] Preferably, a sliding groove is provided on one side of the top of the knife holder, and a limiting rod is slidably installed in the sliding groove, and the limiting rod is an L-shaped structure. One end of the second spring is fixedly installed on one side of the limiting rod, and the other end of the second spring is fixedly connected to the inner wall of one side of the sliding groove.

[0012] Preferably, a limiting groove is provided on the top of one side of the vertical rod close to the limiting rod, and the limiting groove is adapted to the limiting rod.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] In the utility model, the novel filter cloth air-blowing unloading device is described. When the filter cloth is transmitted on the driving roller through the transmission belt, the filter cake is transmitted on the transmission belt, and air is blown through the air inlet so that the filter cake is air-dried in the air-drying area. At the same time, during the transmission process, the filter cake on the transmission belt is scraped off by a scraper. After long-term use, the scraper needs to be replaced.
