[0036] On this basis, the outer surface of the air outlet plate 3 is provided with an air outlet 4, the outer surface of the air inlet plate 7 is provided with an air inlet 8, the inner surfaces of the air outlet 4 and the air inlet 8 are fixedly provided with a closure assembly 5, and the dust collector box is fixedly provided with a cloth bag filter assembly 12 inside.

[0037] Further combined Figure 7 As shown in the figure, in some modes of the example, the air inlet 8 in the cloth bag dust collector is preferably located at the side of the air inlet plate 7 close to the bottom plate 1, and the air outlet 4 is preferably located at the side of the air outlet plate 3 close to the top plate 10.

[0038] Therefore, during the assembly of the bag dust collector, the air inlet plate 7 is installed on the bottom plate 1 according to the design requirements, so that the air inlet 8 is close to the bottom plate 1, and the air outlet plate 3 is installed, so that the air outlet 4 is close to the top plate 10, which is beneficial to form a reasonable air flow path. After the air inlet from the bottom, due to the action of gravity and air flow rising, the dust particles are fully contacted and filtered with the bag during the rising process, and the filtered clean air is naturally discharged from the top air outlet 4, so that the whole dust removal process is more smooth and efficient, reduces the influence of air flow turbulence on the dust removal effect, and improves the working efficiency and stability of the dust collector.

In the starting stage, the electric shutter 504 of the air inlet 8 can be slowly opened, so that the air flow enters smoothly and avoids the impact of instantaneous large air volume on the bag. In the shutdown stage, the electric shutter 504 of the air outlet 4 can be closed first to prevent external air from flowing into the dust collector, thereby protecting the internal components and filter material and improving the reliability and automation level of the equipment operation.

[0043] Further combining Figure 4 With Figure 5 As shown in the drawings, in some modes of the present example, the bag filter assembly 12 in the bag filter includes a connecting frame 1201, the outer surface of the connecting frame 1201 is provided with a mounting groove 1202, the inner surface of the mounting groove 1202 is provided with a limiting frame 1203, and the inner surface of the limiting frame 1203 is provided with a limiting groove 1204. The connecting frame 1201 provides overall support and positioning for the entire bag filter assembly 12, so that it can be accurately installed and fixed in the dust collector box. The cooperation of the mounting groove 1202 and the limiting frame 1203 makes the limiting frame 1203 firmly installed and less likely to shift, thereby providing a precise positioning basis for the subsequent installation of the bag frame 1205 and the bag body 1206, ensuring the structural stability of the bag filter assembly 12, and being conducive to improving the reliability and filtering effect of the bag during the filtering process and reducing problems such as incomplete filtering or bag damage caused by bag shaking and deviation.

[0044] Further, the bag frame 1205 and the bag body 1206 are preferably arranged on the inner surface of the limiting groove 1204, and the limiting groove 1204, the bag frame 1205 and the bag body 1206 are in one-to-one correspondence. The bag frame 1205 and the bag body 1206 are provided with the same plurality of equidistantly distributed bag frames 1205 and bag bodies 1206. The equidistant distribution of the plurality of bag frames 1205 and bag bodies 1206 can make the air flow uniformly pass through each bag, increase the contact area and contact opportunity of dust and the bag, make the filtering more sufficient, improve the dust removal efficiency, and facilitate operation when cleaning or replacing the bag, so that the bag needing maintenance can be quickly positioned and processed, thereby reducing the maintenance difficulty and cost.
