example

[0037] The filter box is divided into an air inlet cavity at the bottom and an air outlet cavity at the top through a partition. The partition is provided with a through hole corresponding to each opening and closing plate. The filter barrel is located in the intake cavity and the upper end The openings correspond to the through holes.

[0038] The filter barrels 6 are a group, and the recoil air pipe in each filter barrel is connected with the compressed air pipeline through an independent pulse valve 13, and the opening end of the corresponding filter barrel is provided with a switch to control the opening and closing of the opening end of the filter barrel Plate 8 is provided with a lifting cylinder corresponding to the opening and closing plate, and the opening and closing plate is driven to move up and down by the lifting cylinder, thereby controlling the opening and closing of the upper opening of the filter barrel, and the opening and closing plate is also controlled by ...

Abstract

The invention discloses a self-cleaning universal filtering device, which comprises a filtering box body, the filtering box body is provided with an air inlet pipe for waste gas to enter and an air outlet pipe for filtered gas to be discharged, the device also comprises a filtering barrel which is arranged in the filtering box body, wherein the filtering barrel is of a hollow structure with an opening in one end, the filtering barrel comprises a back-flushing air pipe arranged inside and a metal filtering structure arranged outside the back-flushing air pipe, an air inlet cavity communicated with the air inlet pipe and an air outlet cavity communicated with the air outlet pipe are formed in the filtering box body, an opening in one end of the filtering barrel is communicated with the air outlet cavity, and the metal filtering structure is located in the air inlet cavity. The filtering structure can be in contact with an internal backflushing gas pipe, the backflushing effect is good, waste gas containing oil and water can be filtered, and accumulated ash is efficiently removed. One group of filtering structures are arranged side by side, one filtering structure is closed for backflushing cleaning, other filtering structures operate normally, and the filtering structures do not need to be taken out and production does not need to be stopped during cleaning.

Description

technical field [0001] The invention relates to the technical field of filtration, in particular to a self-cleaning universal filter device. Background technique [0002] At present, most of the exhaust gas filter devices are cloth bag filter barrels, which have small filter aperture and good filtering effect; but they can only filter dust and particulate matter, and cannot filter exhaust gas containing oil and water. Oil, water and dust are mixed and easily stuck in the cloth bag. If the back blowing structure is close to the cloth bag, the back blowing effect will be poor. If the back blowing structure is close to the cloth bag, the bag structure will be damaged. [0003] In order to ensure the filtering effect, the waste gas containing oil and water is mostly filtered with a filter plate with small holes. In order to ensure the filtration capacity, the filter plate has a large area and takes up a lot of space, which is not easy to arrange and install; and it needs to be t...
