Filtering device

Abstract

The invention provides a filtering device, and relates to a tank type filtering device. The problem that parts in a tank body are difficult to maintain in the prior art is solved. A filtering structure and a staining solution filtering system comprise a tank body, and a conical filter screen is arranged in the tank body. A liquid inlet is formed in the portion, above the conical filter screen, ofthe tank body. A liquid outlet is formed in the portion, below the filter screen, of the tank body. Dragging type scrapers are arranged on the conical filter screen, the dragging type scrapers are connected to a rotating shaft through a support, the rotating shaft is rotationally arranged in the tank body, the dragging type scrapers and the support are connected in a plugging mode through rotatable plug pins, and disassembling and assembling can be achieved through simple pulling and plugging. Liquid flow generated when a liquid suction pump discharges liquid is used for driving stirring scraper plates to rotate, rapid installation of the dragging type scrapers is achieved in a plugging connection mode, an arranged rotating speed control device facilitates control over the rotating speedsof the dragging type scrapers, and a split type speed adjusting plate installation mode facilitates operation through a maintenance peephole of the tank body.

Description

technical field [0001] The invention belongs to the technical field of filtration and relates to a tank type filtration device. Background technique [0002] The tank type filter device is widely used, especially suitable for rapid filtration of large impurities in the liquid, especially in the process of printing and dyeing, it is used to filter the dyeing liquid containing impurities such as cotton wool, so as to facilitate the recycling of the dyeing liquid, and the sewage or Used dyes turned waste into treasure. [0003] As shown in the patent application document titled "Automatic Filtration System Mechanism of Printing and Dyeing Machine and Its Control Method (Publication No. CN110180237A)" disclosed in the Chinese patent literature, it uses the impact force of the liquid flow entering the pipe body to make use of The dragging scraper continuously cleans the filter screen, thereby avoiding the clogging of the mesh and improving the filtration speed, and the stirring ...

AI Technical Summary

Problems solved by technology

However, since the dragging scraper in this patent is set in the tank body, it can only operate the inside of the tank body through the operating window arranged on the tank body. The operating window is small, which is inconvenient to replace the dragging scraper, and it is troublesome to disassemble. , the rotating power of the dragging scraper and stirring scraper of the filter system with the above structure is completely provided by the impact force of the liquid flow entering the pipe body, which is greatly fluctuated by the liquid flow and unstable in operation, especially the liquid accumulated in the tank The more, the greater the resistance to the stirring scraper, which hinders the rotation of the dragging scraper, resulting in poor cleaning effect of the filter screen, hindering the passage of water, and further hindering the rotation of the dragging scraper until finally stalled, The filter screen is clogged, so an improvement is implemented on the basis of the above-mentioned patents
