Description

Technical Field

[0001] The utility model relates to the technical field of gas filters, in particular to an eccentrically installed filter with a filter element interface. Background Art

[0002] The gas filter consists of a shell, a multi-element filter element, a backwash mechanism, an electric control box, a reducer, an electric valve and a differential pressure controller. The transverse partition in the shell divides its inner cavity into an upper and lower cavity. The upper cavity is equipped with multiple filter elements, which fully utilizes the filtration space and significantly reduces the volume of the filter. A backwash suction cup is installed in the lower cavity. When working, turbid liquid enters the lower cavity of the filter through the inlet and enters the inner cavity of the filter element through the partition hole. Impurities larger than the gap of the filter element are retained, and the clean liquid passes through the gap to reach the upper cavity and is finally sent out from the outlet.

[0003] The filter element interface of the traditional filter is on the same center line as the filter element and the filter body. In order to meet the filter element flow rate and ensure that the air outlet and air inlet flows are the same, the size of the filter body (width L and diameter D) must be increased so that the area of ​​the filter element outlet position can meet the requirements of the air inlet. Therefore, the traditional filter is large in size and weight, requires a larger installation space, increases the difficulty of installation, and is also more expensive. Therefore, a filter with an eccentrically installed filter element interface is proposed. Utility Model Content
