[0019] In order to clearly and completely describe the purpose and technical solution of the present invention and make its advantages more clearly understood, the following is a further detailed description of the embodiments of the present invention in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only part of the embodiments of the present invention, not all of them, and are only used to explain the embodiments of the present invention and are not intended to limit the embodiments of the present invention. All other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0020] See also Figure 1-Figure 4The present invention provides a technical solution: a dust filter bag for a bag filter, comprising a bag top 1, an interior of which is provided a covering cavity 2, a plurality of wire rings 3 being fixed within the covering cavity 2. The wire rings 3 are arranged in a vertical arrangement at equal distances and sizes. The bag top 1 is mounted on the top of a frame, typically with the upper end of the bag clamped and mounted on the top of the frame. The wire rings 3 are added to the bag top 1 to facilitate upward installation on the frame after the bag top 1 is expanded.
[0021] The bottom end of the filter bag top 1 is fixed with a filter bag connecting portion 4, which is connected to the filter bag cover 5 via a zipper strip 6 and a zipper 7. The bottom end of the filter bag connecting portion 4 and the top end of the filter bag cover 5 are both fixed with zipper strips 6, and the two sets of zipper strips 6 are connected by a zipper 7. Through the coordinated connection between the filter bag connecting portion 4 and the filter bag cover 5, the filter bag top 1 and the filter bag cover 5 are optimized to a detachable structure. In this way, when replacing the filter bag cover 5, it is necessary to separate the filter bag top 1 from the frame, and only the zipper strips 6 of the filter bag connecting portion 4 and the filter bag cover 5 need to be separated. This operation is simple and convenient, and the filter bag top 1 can be recycled.
[0022] The bottom surface of the filter bag top 1 is fixed with a guard piece 1 8 and a guard piece 2 9, which are distributed on both sides of the filter bag connection part 4, and the heights of the guard piece 1 8 and the guard piece 2 9 are both greater than the height of the filter bag connection part 4; the top of the filter bag cover 5 is fixed with a magic patch 10 on the inner and outer ring surfaces, and the inner ring surface of the guard piece 1 8 and the outer ring surface of the guard piece 2 9 are fixed with a magic patch 11, and the magic patch 10 and the magic patch 11 are connected in cooperation; the reason for adding guard piece 1 8 and guard piece 2 9 at the bottom of the filter bag top 1 is to cover the connection between the two zipper strips 6, and through the cooperation of the magic patch 10 and the magic patch 11, the guard piece 1 8 and the guard piece 2 9 are respectively connected to the two sides of the filter bag cover 5, thereby realizing the traction effect when the filter bag connection part 4 and the filter bag cover 5 are connected to a certain extent.
