Filtering device with self-cleaning function

Abstract

The filtering device with the self-cleaning function comprises an outer cylinder, an inner cylinder, a lower fixing ring, a plurality of cotton wool ropes and an upper fixing ring, the outer cylinder and the inner cylinder are matched to form a transition cavity, and a flow channel communicated with the transition cavity is formed in the cylinder wall of the inner cylinder; wherein the cylinder bottom position of the outer cylinder is communicated with a lower inlet pipe and a lower discharge pipe, the cylinder top position of the inner cylinder is communicated with an upper outlet pipe and an upper inlet pipe, one end of each cotton wool rope is installed at the cylinder bottom position of the inner cylinder through a lower fixing ring, and the other end of each cotton wool rope is rotatably installed at the cylinder top position of the inner cylinder through an upper fixing ring. And the upper fixing ring can simultaneously drive the plurality of cotton wool ropes to rotate relative to the inner cylinder, so that the plurality of cotton wool ropes are matched with one another and wrap the flow channel of the inner cylinder. According to the invention, self-cleaning of the cotton wool rope can be realized, so that continuous and long-acting work of the filtering device is realized, and the use requirements of enterprises are met; meanwhile, the filtering device is simple in structure and convenient to operate and control, and the use requirements of enterprises are further met.

Description

technical field [0001] The invention belongs to the technical field of impurity filtering, and in particular relates to a filtering device with a self-cleaning function. Background technique [0002] At present, the existing filtering device for filtering impurities in water usually adopts the mesh structure of the filter screen to filter the impurities in the water. However, the rigid structure of the filter screen is used to filter the impurities in the water, which cannot be achieved The self-cleaning of the screen, for this reason, when the filter screen is blocked, the filter device needs to be shut down for cleaning, which will affect the use effect of the filter device. SUMMARY OF THE INVENTION [0003] In view of this, it is necessary to provide a filter device with self-cleaning function for solving the above technical problems. [0004] A filter device with self-cleaning function, comprising an outer cylinder and an inner cylinder arranged in the outer cylinder,...

Problems solved by technology

[0002] At present, the existing filter devices for filtering impurities in water usually use the mesh structure of the filter to filter the impurities in the water. However, the rigid structure of the filter is used to filter the impurities in the water, and it is impossible to filter The self-cleaning of the net, for this reason, when the filter net is clogged, the filter device needs to be shut down for cleaning, which will affect the use effect of the filter device
