Fluid filter device with detachable tank

Abstract

A fluid filtering device with a detachable tank body, comprising a processing tank, a driving unit, a water production pipe and a filtering unit. The treatment tank is a cubic hollow tank body formed by adjoining and surrounding multiple substrate units. The substrate units can be expanded and extended by splicing boards in equal proportions, and the outer side of each board is in the shape of an outer drum, so that the board body At least one circular recess is formed on the inner side. The water production pipe is connected with the drive unit and includes several embedding parts protruding on the outer wall along the length direction. The water guide plate of the filter unit is provided with several joint parts, and the joint parts of the water guide plate correspond to the embedding parts and are assembled on the water production pipe. The invention allows the treatment tank to be disassembled to change the volume, and also has the function of accommodating the filter membrane.

Description

technical field [0001] The present invention relates to a fluid filtering device, and in particular to a fluid filtering device with a detachable tank which allows the treatment tank to be disassembled to change volume and has the function of accommodating filter membranes. Background technique [0002] In order to suppress the formation of sludge (filter cake) on the surface of the filter membrane, the previous filtrate treatment equipment, in addition to cleaning or backwashing to remove fouling, also uses the shear flushing generated by membrane rotation To reduce the accumulation and fouling of particles on the membrane surface, thereby prolonging the operating cycle of the membrane. [0003] However, for feed water with high solid content and high viscosity, the above-mentioned treatment methods often cannot achieve a good solid-liquid separation effect. Therefore, the applicant has developed a filter device that can meet the above feed water conditions , such as China...

AI Technical Summary

Problems solved by technology

[0005] 1. The treatment tank cannot be randomly expanded: because the previous treatment tanks were made in a stereotyped form, they must be welded and fixed before the overall assembly, and the capacity of the feed water treatment cannot be expanded at will, so the variability is low, and the huge tank body It is also quite inconvenient when transporting

[0006] 2. Insufficient connection strength of the components: Because the element for the rotation of the filter bag is to use the water production pipe to drive synchronously, and the connection between the water production pipe and the filter bag is only locked and tightened by the nuts and bolts at both ends, so once processed The viscosity of the feed water is relatively high, so the resistance generated by the rotation of the filter bag will be relatively greater, so after a period of operation, the bolts are prone to chipping, and then the embedded water guide plates that are embedded in each other The connection block will also gradually break, so that the water production pipe will not be able to drive the filter bag to rotate, and further, the scraper assembly will lose the effect of scraping and cleaning the surface of the filter bag

[0007] 3. The filter bag is easy to be scratched: Since the previous mud scraping component adopts a fixed structure and directly contacts the membrane surface, after the membrane has been subjected to continuous friction by the mud scraping component for a long time, the anti-scaling material layer on the membrane surface is very Scratches easily, resulting in frequent filter bag changes
