Description

Technical Field

[0001] This utility model relates to a detection device, and more particularly to a filter bag damage detection device for bag filters, belonging to the field of filter bag technology. Background Technology

[0002] Filter bags are a crucial component in the operation of baghouse dust collectors. Typically, cylindrical filter bags are suspended vertically within the dust collector. The fabric and design of the filter bags should prioritize high-efficiency filtration, easy dust removal, and durability. In pulse-jet and box-type pulse-jet dust collectors, dust adheres to the outer surface of the filter bag. When dust-laden gas passes through the dust collector, the dust is captured on the outer surface of the filter bag, while clean gas passes through the filter media and enters the interior of the filter bag. After a period of use, the appearance of the filter bags needs to be inspected to prevent damage.

[0003] The application with application number "202120759288.6" discloses "a rapid detection device for filter bag damage," which "includes an L-shaped plate, a toggle ring on one side of the bottom of the L-shaped plate, a plurality of first connecting rods installed at the bottom of the toggle ring, a positioning ring fixedly connected to the bottom of the first connecting rod, and movable rods movably passing through the four outer perimeter of the positioning ring, with an arc-shaped pressure block fixedly sleeved at one end of the movable rod, and a return spring sleeved on the outside of the movable rod." In this utility model, during filter bag detection, the filter bag is placed over the positioning ring, and the movable rods and arc-shaped pressure blocks are pulled outwards sequentially using various handles. Releasing the handles allows the arc-shaped pressure block to press against the outside of the filter bag through the return spring, thus fixing the filter bag. Air is blown into the inside of the filter bag through a blower pipe, causing the filter bag to inflate. Simultaneously, the filter bag can be rotated by the toggle ring, allowing for thorough inspection of the filter bag surface, providing convenience for workers.

[0004] However, the above method still has the following drawbacks: using an arc-shaped pressure block to press on the outside of the filter bag and using air blowing to detect the damaged location of the filter bag; however, in actual application, when installing and testing the filter bag, the operator needs to repeatedly pull each handle to fix the filter bag through the arc-shaped pressure block. This operation not only increases the difficulty of operation, but also prolongs the installation time of the filter bag, which in turn affects the efficiency of subsequent filter bag testing to a certain extent.
