Description

Technical Field

[0001] The utility model relates to the technical field of filter bag type filters, in particular to a high-performance filter element filter bag used in a paint mixing room. Background Art

[0002] A bag filter, also known as a bag filter, is a pressure-type filtering device that can filter liquids such as water, paint, and beer. It has the advantages of small size, large dirt holding capacity, and easy replacement of the filtering device. When it is used, the quality of the filter element plays a decisive role in the filtering effect of the device. However, the existing filter elements for bag filters still have some shortcomings when used.

The filter element of the filter bag type filter is provided with a first elastic airbag and a second elastic airbag. After the device is installed, the first elastic airbag is squeezed through a flange or an external connection mechanism, so that the volume of the second elastic airbag expands and fits with the inner wall of the filter, thereby improving the overall stability of the device after installation and avoiding the phenomenon of liquid penetration at the connection.

[0004] However, the above device only stirs the liquid inside the filter element through the cross bar to improve the filtering effect. When impurities adhere to the inner wall of the filter element, the impurities cannot be washed down by the rotating liquid alone, and the impurities will clog the filter element, which has certain shortcomings.
