Abstract

The invention discloses a filter device. The filter device comprises a lower cylinder, a filter basket which is arranged inside the lower cylinder, a liquid outlet which is formed in the lower portion of the lower cylinder, a pneumatic blow-down valve which is arranged at the bottom of the lower cylinder, an upper cylinder, a liquid inlet which is formed in the upper cylinder and guides liquid to the filter basket, a scrapping plate which is arranged inside the lower cylinder and is used for scrapping the filter basket, a scrapping plate pull rod and a scrapping plate air cylinder; the upper end of the upper cylinder is connected with an air cylinder fixing lower plate through at least one second air cylinder; the second air cylinder drives the fixing lower plate to go up and down; the lower end of the upper cylinder and the lower cylinder are clamped in a sealing mode; one end of the scrapping plate pull rod is connected with the scrapping plate and the other end is connected to an air cylinder fixing upper plate; the scrapping plate air cylinder drives the scrapping plate to vertically move along the height direction of the filter basket through the scrapping plate pull rod. The filter device allows self-cleaning and the scrapping plate moves vertically on the surface of a filter screen to remove filtration residue from the surface of the filter screen when a filter core requires to be washed.

Description

technical field [0001] The invention relates to a filter device, in particular to a filter device capable of self-cleaning. Background technique [0002] Although the existing filter device can filter liquid through the filter screen, after a long period of use, the filter screen will be blocked by residues, which greatly reduces the filtering effect. [0003] In view of this, the inventors in the field provide a self-cleaning filter device to solve the above problems. Contents of the invention [0004] The invention provides a filtering device, overcomes the difficulties of the prior art, and provides a filtering device capable of self-cleaning. [0005] The invention provides a filtering device, comprising: [0006] Lower cylinder; [0007] a filter basket arranged inside the lower cylinder; [0008] The liquid outlet is arranged at the lower part of the lower cylinder; [0009] Pneumatic blowdown valve, arranged at the bottom of the lower cylinder; [0010] The up...
