Gas filter with rotary scraper

Abstract

The invention discloses a gas filter with a rotary scraper. The gas filter is composed of a housing, a motor, a support, a sealing device, a scraper device, a discharging device and a filtering plate. The housing is provided with a gas inlet, a gas outlet and an impurity removing port; the discharging device is installed at the impurity removing port; the motor is fixed to the housing through the support, and a motor shaft of the motor extends into the housing; the filtering plate is provided with through air holes; the filtering plate is installed between the gas inlet and the gas outlet and fixed to the housing; the scraper device is installed on the portion, extending out of the filtering plate, of the motor shaft, the motor drives the scraper device to remove impurities on the filtering plate continuously through the motor shaft, and the impurities scraped off from the filtering plate are discharged through a discharging valve of the impurity removing port. The gas filter can filter gas continuously, and the filtering plate increases the passing speed in gas filtration and optimizes the gas filtering effect; it is not needed to replace or clean the filtering plate in working, and thus the waste of labor and materials is reduced.

Description

technical field [0001] The invention relates to a gas filter, especially a gas filter with a rotating scraper. Background technique [0002] In the process of industrial production, the filters used to filter and purify the gas are all static filters. The impurities in the gas are filtered through different filters. The filters in the process of filtering the gas are all stationary, and the impurities adhere to the filter Over time, it will cause the mesh of the filter to be clogged, which will affect the effect of gas filtration. The filter cannot clean the impurities on the filter screen during the working process. At this time, it must stop working to continuously replace and clean the filter screen, resulting in waste of labor and materials. [0003] I invented a patent spinner gas filter (patent number: 201520401609X), which consists of a casing, a motor, a bracket, a sealing device, and a spinner filter device. There are air inlets, air outlets, and miscellaneous out...

AI Technical Summary

Problems solved by technology

[0004] Because the spinner filter device of the spinner gas filter cleans the impurities on the filter screen during the working process, it relies on the centrifugal force of the gravity of the impurities to get rid of the impurities, but sometimes when the impurities adhered to the filter cannot be shaken off, the impurities will cause the filter The air permeability of the mesh needs to be further improved on the supporting equipment of the disc type gas filter
