Description

Technical Field

[0001] The utility model belongs to the technical field of bag dust collectors, and in particular relates to a bag dust collector that is easy to repair. Background Art

[0002] A bag filter is a highly efficient dry dust collector that relies on filter bags made of fiber filter media. More importantly, it purifies the gas through the dust layer formed on the surface of the filter bag. Its dust removal efficiency can reach over 99% for almost all dust in general industry.

[0003] When an existing bag dust collector is performing dust removal processing and its internal structure fails and needs to be repaired and maintained, the staff will remove the top cover and then enter the interior to carry out repair and maintenance. However, there are the following defects: (1) The top cover of the bag dust collector is installed with a bolt assembly. The bolt assembly needs to be repeatedly screwed multiple times during disassembly and assembly, which makes it inconvenient to disassemble and assemble the top cover, thereby causing the bag dust collector to be laborious and inconvenient to repair. For this reason, we propose a bag dust collector that is easy to repair. Utility Model Content

[0004] The purpose of the utility model is to provide a bag dust collector that is easy to maintain, so as to solve the problem that the top cover of the bag dust collector proposed in the above background technology is installed with a bolt assembly, which makes it inconvenient and laborious to disassemble and assemble the top cover, thereby affecting maintenance.

[0006] Preferably, the mounting column assembly consists of an end column, a bottom column and an adjustment structure, a side wall of the end column is provided with a locking groove with a circular cross section, and one end of the locking block is placed inside the locking groove.

[0007] Preferably, the adjustment structure consists of a threaded column and a threaded groove, the threaded groove is provided on the bottom end surface of the end column, the threaded column is fixed on the end surface, and the threaded column and the threaded groove are connected by threads.

[0008] Preferably, a blocking hole is opened on the surface of the locking block, a blocking column is provided inside the blocking hole, and the blocking column is fixed on the inner wall of the side tube.

[0009] Preferably, a through hole is formed at the other end of the locking block, and a pull ring is connected to the through hole.

[0010] Preferably, a spring is sleeved on the outer wall of the other end of the locking block, and the spring is located inside the side tube.

[0011] Preferably, the cross section of the fixing sleeve is a circular structure, and the longitudinal section of the locking block is a T-shaped structure.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] (1) The top cover is placed on the top of the dust collector body through the designed mounting column assembly, fixing sleeve, side cylinder and locking block. When placing the top cover, the mounting hole on the surface of the top cover passes through the mounting column assembly, and then the fixing sleeve is put on the mounting column assembly. One end of the locking block is stuck in the locking groove on the surface of the mounting column assembly to achieve labor-saving and fast fixing of the top cover. At the same time, when inspecting and disassembling, it is only necessary to pull the locking block to disengage one end of it from the locking groove, and then remove the fixing sleeve. This makes the installation of the utility model more labor-saving, convenient and quick than the traditional stud assembly. Through the designed adjustment structure, the end column is rotated to adjust the thread groove and the thread column by screwing the thread, so as to achieve the overall height adjustment of the mounting column assembly, so that the fixing sleeve and the mounting column assembly can be used to lock and fix top covers of different thicknesses. Through the designed blocking column and blocking hole, the locking block is limited to slide and prevented from disengaging from the side cylinder. Through the designed spring, the spring exerts elastic squeezing action on the locking block, so that one end of the locking block is stuck in the locking groove more firmly.
