Description

Technical Field

[0001] This utility model belongs to the field of primary filter application technology, specifically relating to a bag-type framed filter bag. Background Technology

[0002] The outer frame of the G4 primary bag air filter is available in galvanized steel or aluminum alloy, with thicknesses of 20mm, 25mm, and 45mm (optional).

[0003] Pre-filter bags can be used in ventilation systems for pre-filtration. Each filter bag is secured with a metal strip, which increases the strength of the filter bags, ensures uniform airflow, and prevents the filter bags from breaking due to wind shear friction at high wind speeds.

[0004] Each G4 pre-filter bag has six septa evenly distributed across its width to prevent excessive expansion and mutual obstruction of the filter bags under wind pressure, thus reducing the effective filtration area and efficiency. Each filter bag edge is ultrasonically fused, ensuring excellent airtightness and bonding strength, preventing leaks or ruptures.

[0005] Currently, most common bag-type framed filter bags on the market are integral designs consisting of an outer frame and a fixed fiber filter bag. The problems with this design are that when the fiber filter bag breaks or the adsorption and filtration effect is poor, it is inconvenient to replace it, and the replacement process is time-consuming. This affects the normal operation of the equipment it is installed on and indirectly reduces the production efficiency of the workshop.

[0006] Therefore, based on the above problems, this utility model provides a bag-type framed filter bag. Utility Model Content

The lower fixed plate and the fiber filter bag fixing plates are fastened together using second bolts through the screw grooves and through holes. The fiber filter bag is fixedly mounted on the fiber filter bag fixing plate.

[0009] In this technical solution, the bag-type framed filter bag further includes strip-shaped clamping plates symmetrically arranged on the outer wall of the same side of the rectangular transition plate; wherein, the connecting surfaces of the rectangular transition plate and the strip-shaped clamping plates form a transverse U-shaped structure.

[0010] In this technical solution, the air inlet cavity, the rectangular lower fixing plate groove, and the fiber filter bag fixing plate groove are all the same size; wherein, the air inlet cavity, the rectangular lower fixing plate groove, and the fiber filter bag fixing plate groove are all set as rectangular structures.

[0011] In this technical solution, the rectangular plate-type metal outer frame and the rectangular lower fixing plate are of the same size.

[0012] In this technical solution, the two end faces of the fiber filter bag fixing plate are flush with the two end faces of the rectangular plate-type metal outer frame and the rectangular lower fixing plate.

[0013] Compared with the prior art, the beneficial effects of the bag-type framed filter bag of this utility model are as follows: 1. Without changing the original rectangular plate-type metal outer frame, several horizontal support plates and several air inlet cavities, a split component structure design is adopted to assemble several fiber filter bags in a convenient and detachable manner, which facilitates disassembly and maintenance, shortens maintenance time and improves production efficiency; 2.
