Abstract

The invention discloses a self-cleaning filter. The filter comprises a cylinder, an upper sealing head, a lower sealing head, an upper baffle and a lower baffle. The upper sealing head and the lower sealing head are connected to the two ends of the cylinder through flanges respectively, the two sides of the upper baffle abut against the cylinder and the upper sealing head respectively, and the twosides of the lower baffle abut against the cylinder and the lower sealing head respectively; a filter element is arranged in the cylinder, the lower baffle is provided with a through hole which is flush with the filter element, and a discharging pipe flush with the through hole is arranged in the lower sealing head; a sealing ring is arranged at the end, close to the through hole, of the discharging pipe, a rotation pipe is communicated with the end, away from the through hole, of the discharging pipe, and a driving shaft is connected with the rotation pipe, penetrates through the lower baffle, the cylinder, the upper baffle and the upper sealing head and then is connected with a driving motor fixed to the upper sealing head; an annular groove which is distributed along the rotation trackof the sealing ring and separated from the through hole is formed in the side, located in the lower sealing head, of the lower baffle, and a filter part is arranged in the annular groove, wherein thesurface of the filter part is flush with the lower baffle, and the diameter of the annular groove is larger than that of the sealing ring. The self-cleaning filter has the advantages that wear of thesealing ring can be reduced, and the service life of the sealing ring is prolonged.

Description

technical field [0001] The invention relates to a filter, in particular to a self-cleaning filter. Background technique [0002] In the production process of dimethyl oxalate hydrogenation catalyst using ammonia distillation, the desalination station is a crucial production component. In the composition of the desalination station, the self-cleaning filter is also an essential part. [0003] The Chinese patent whose publication number is CN108096897A discloses a self-cleaning filter with suction type multi-filter elements. The self-cleaning filter includes a cylinder, which includes a left filter area, a connecting area and a right filter area arranged in sequence, the filter element is arranged in the left filter area and the right filter area, and the side of the cylinder facing the ground is provided with a seal The baffle is isolated from the head, and a through hole is opened on the baffle, and the through hole penetrates the baffle to communicate with the filter elem...
