Novel cleaning apparatus of filtration hole

Abstract

The invention relates to a novel cleaning apparatus of a filtration hole. The novel cleaning apparatus is provided with a filtration core, wherein the filtration core is fixed on the middle disks of the filter, the middle disks sleeve on a main shaft, the main shaft is connected with a drive device, the drive device is arranged on the top portion of the filter housing, the lower portion of the housing is provided with a filtrate inlet, the filtrate inlet and the filtration core are communicated, a filtrate outlet is arranged on the upper portion of the housing, a sewage discharge port is arranged on the bottom portion of the housing, and is connected with an electromagnetic valve, a differential pressure controller is arranged in the housing, the middle disks are provided with a backwashing device and cleaning brushes so as to conveniently clean impurities trapped on the inner surface of the filtration core cavity, one end of the connection rod arranged on the center shaft of the cleaning brush is connected with a cleaning cutter, the shape of the cleaning cutter is V shape, and both side edges of the V-shaped cutter contact the side walls of the filtration hole so as to effectively clear residual impurities in the filtration hole, reduce the resistance on the cleaning cutter during the cleaning process, and improve the work efficiency, such that the water consumption is saved, the time and the labor are saved, the worker labor amount is reduced, and the damage on the filtration core due to frequent disassembly cleaning is reduced.

Description

technical field [0001] The invention relates to a cleaning device for filter cores, in particular to a novel cleaning device for filter holes. Background technique [0002] The wedge-shaped filter element is the filter element on the filter, which is fixed on the middle plate of the filter. Evenly arranged, there are multiple hoops welded in the length direction. The filter element not only has sufficient rigidity and strength to resist deformation, but also can strictly guarantee the accuracy of filtration. As the filtration process continues, solid phase impurities in the liquid are retained. On the surface of the filter element, the pressure drop in the filter element increases, the filtration resistance increases, and the filtration efficiency decreases. At this time, it is generally necessary to interrupt the filtration operation, replace the filter element or take it out for cleaning, which is time-consuming and troublesome, and affects the processing efficiency. At pr...

[0002] The wedge-shaped filter element is the filter element on the filter, which is fixed on the middle plate of the filter. Evenly arranged, there are multiple hoops welded in the length direction. The filter element not only has sufficient rigidity and strength to resist deformation, but also can strictly guarantee the accuracy of filtration. As the filtration process continues, the solid phase impurities in the liquid are retained. On the surface of the filter element, the pressure drop in the filter element increases, the filtration resistance increases, and the filtration efficiency decreases. At this time, it is generally necessary to interrupt the filtration operation, replace the filter element or take it out for cleaning, which is time-consuming and troublesome, and affects the processing efficiency. At present, there is an automatic reverse filter. The flushing water filter can automatically clean the filter element through the flushing of the clear liquid filtered by the water filter. This self-cleaning not only wastes water, but also does not clean it, especially the impurities remaining in the gap filtered by the filter element. Effective cleaning, long-term use requires frequent replacement of filter media or manual cleaning of filter elements
