Description

Technical Field

[0001] The utility model relates to the technical field of dust removal filter bags, in particular to a filter bag frame which is easy to replace. Background Art

[0002] The filter bag frame is a structure used to support and fix the filter bag, which is commonly found in pulse dust collectors, bag dust collectors and other equipment. Its function is to keep the shape of the filter bag stable, prevent the filter bag from collapsing or deforming, and provide sufficient support to resist the impact of airflow and particulate matter.

[0003] After searching, the Chinese patent with the authorization announcement number CN214597837U discloses a filter bag frame that is easy to replace, including a bottom plate, a fixing rod is fixedly installed on the upper end of the bottom plate, and a fixing head is arranged on the upper end of the fixing rod, a clamping structure is arranged on the fixing head, and the clamping structure includes an annular groove, a first clamping sleeve, a second clamping sleeve, a rotating head, a threaded hole, a round hole and a fastening screw, and a mounting head is arranged on the upper end of the fixing head. The filter bag frame that is easy to replace described in the utility model belongs to the field of dust removal mechanism, adopts a clamping structure, and uses a clamping sleeve to install and fix the filter bag, which can effectively fix the filter bag, and at the same time can ensure the stability of the filter bag after being fixed, and ensure the use effect. Through the installation head, the rubber sleeve and other structures are used to ensure the sealing during installation, and the rubber sleeve can form a certain buffer when the frame is installed, protecting the installation plate and other structures, and it is also convenient for installation and disassembly.

[0004] However, in the prior art, bolts are usually used to fix the filter bag to the frame. Since the filter bag will continue to expand and contract in the dust collector and generate vibration, the single bolt fixing structure is easy to loosen and fall off due to vibration, resulting in poor fixing effect of the filter bag. Therefore, we propose a filter bag frame that is easy to replace to solve this problem. Utility Model Content

[0005] The utility model is to solve the problem in the prior art that bolts are usually used to fix the filter bag on the frame.

[0011] In the utility model, the filter bag frame which is easy to replace is described. By inserting the screw into the through hole located on the right side, and then rotating the thread sleeve on the screw, the ferrule can be tightened, and the distance between the two connecting plates can be contracted. At the same time, the connecting rod is rotated, so that the semicircular clamping block can be driven to rotate synchronously. When the semicircular clamping block is aligned with the semicircular groove, the elastic force of the spring can drive the connecting rod to move, so that the semicircular clamping block can be clamped into the semicircular groove, and the ferrule can be further fixed.

[0012] The utility model provides a fixing mechanism with a double fixing device including a connecting rod and a screw, so that the filter bag can be more firmly installed on the frame, avoiding the leakage of the filter bag due to the screw falling off due to vibration after long-term use, and the installation effect is good.
