[0026] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution of the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings of the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the described embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Example 1: Please refer to Figures 1 to 6 :

[0028] The utility model proposes a dust removal device, comprising: a dust removal shell 1;

[0029] A suction pipe 2 is arranged on the top of the dust removal shell 1. The dust removal shell 1 is used to support the suction pipe 2 and rotatably support the dust filter cylinder 3 inside it. The suction pipe 2 can be connected to the external suction fan during installation. The external suction fan can be turned on during use. When the suction fan is working, the air in the annular cavity between the outer wall of the dust filter cylinder 3 and the inner wall of the dust removal shell 1 will be drawn out through the suction pipe 2. A dust filter cylinder 3 is rotatably installed inside the dust removal shell 1. The dust filter cylinder 3 is used to filter and collect dust in the electrical automation equipment. When in use, the air and dust in the electrical automation equipment will pass through the upper part of the outer wall of the rear side of the dust removal shell 1 The semicircular opening at the position enters into the semicircular cavity above the inner side of the dust filter cartridge 3, so the dust filter cartridge 3 can filter and collect the dust, and when the dust in the dust filter cartridge 3 needs to be cleaned, it is only necessary to rotate the semicircular cavity filled with dust to the bottom, and then the dust in the dust filter cartridge 3 can be cleaned outwards through the semicircular opening at the lower position of the outer wall of the front side of the dust removal shell 1; an inner baffle plate 4 is also welded to the inside of the dust removal shell 1, and when in use, the inner baffle plate 4 will be in close contact with the outer wall of the lower part of the dust filter cartridge 3, so the semicircular cavity below the inner side of the dust filter cartridge 3 can be isolated from the annular cavity inside the dust removal shell 1, so that only The semicircular opening on the outer wall of the rear side of the dust removal shell 1 draws air inward; a dust filter partition 5 is welded on the inner side of the dust filter cartridge 3, and the dust filter partition 5 is used to separate the cavity in the dust filter cartridge 3; a dust filter cartridge adjustment handle 6 is provided on the front side of the dust filter cartridge 3, and the dust filter cartridge adjustment handle 6 is used to support the positioning plate 7, and when the dust filter cartridge 3 is rotated, the dust filter cartridge adjustment handle 6 can be held to drive it to rotate; a positioning plate 7 is slidably installed on the dust filter cartridge adjustment handle 6, and when the dust filter cartridge 3 needs to be rotated and adjusted, the positioning plate 7 is first pulled forward, and at this time, the front end of the positioning column 8 will be disengaged from the circular holes on both sides of the positioning plate 7, so that The dust filter cartridge 3 is driven to rotate 180° by the dust filter cartridge adjusting handle 6. At this time, the semicircular cavity filled with dust on the inner side of the dust filter cartridge 3 will rotate downward and connect with the semicircular opening at the lower position of the front outer wall of the dust removal shell 1. Then the positioning plate 7 can be loosened. At this time, the magnet plate on the front side of the dust filter cartridge adjusting handle 6 will push the positioning plate 7 to slide backward. Then the front end of the positioning column 8 will be re-embedded in the circular holes on both sides of the positioning plate 7. Therefore, the dust filter cartridge 3 can be locked by the positioning plate 7. Two positioning columns 8 are symmetrically arranged on the front outer wall of the dust removal shell 1. The positioning columns 8 cooperate with the positioning plate 7 to lock the dust filter cartridge 3.

[0030] In the present disclosure, Figure 1 , Figure 4 and Figure 6As shown, the positioning plate 7 can slide back and forth on the outer side of the rectangular rod of the dust filter cartridge adjustment handle 6, and a circular hole with the same outer diameter as the positioning column 8 is provided on the left and right sides of the positioning plate 7. When the dust filter cartridge 3 needs to be rotated and adjusted, the positioning plate 7 is first pulled forward. At this time, the front end of the positioning column 8 will be disengaged from the circular holes on both sides of the positioning plate 7. Therefore, the dust filter cartridge 3 can be driven to rotate 180° through the dust filter cartridge adjustment handle 6. At this time, the semicircular cavity filled with dust on the inner side of the dust filter cartridge 3 will rotate to the bottom and be connected with the semicircular opening at the lower position of the front outer wall of the dust removal shell 1. Then the positioning plate 7 can be loosened. At this time, the magnet plate on the front side of the dust filter cartridge adjustment handle 6 will push the positioning plate 7 to slide backward, and then the front end of the positioning column 8 will be re-embedded in the circular holes on both sides of the positioning plate 7. Therefore, the dust filter cartridge 3 can be locked through the positioning plate 7.

[0031] In the present disclosure, Figure 3 and Figure 4 As shown, the dust filter cartridge 3 is a cylinder with openings on the front and rear sides. There is an annular cavity between the outer wall of the dust filter cartridge 3 and the inner wall of the dust removal shell 1, and the suction pipe 2 is connected to the annular cavity. When in use, the external suction fan can be turned on. When the suction fan is working, the air in the annular cavity between the outer wall of the dust filter cartridge 3 and the inner wall of the dust removal shell 1 will be drawn out through the suction pipe 2. At this time, the air in the semicircular cavity above the inner side of the dust filter cartridge 3 will enter the annular cavity inside the dust removal shell 1 through the small holes on the outer wall of the dust filter cartridge 3. At the same time, the air and dust in the electrical automation equipment will enter the semicircular cavity above the inner side of the dust filter cartridge 3 through the semicircular opening above the outer wall of the rear side of the dust removal shell 1. Therefore, the dust filter cartridge 3 can filter and collect dust.

[0032] In the present disclosure, Figure 1-Figure 3 As shown, when the front end of the positioning column 8 is embedded in the circular holes on the left and right sides of the positioning plate 7, the semicircular cavity on the upper inner side of the dust filter cartridge 3 will be connected with the semicircular opening on the rear outer wall of the dust removal shell 1, and the semicircular cavity on the lower inner side of the dust filter cartridge 3 will be connected with the semicircular opening on the front outer wall of the dust removal shell 1. Therefore, when cleaning the dust in the semicircular cavity on the lower inner side of the dust filter cartridge 3, the semicircular cavity on the upper inner side of the dust filter cartridge 3 can still play the role of filtering dust.

[0033] In the present disclosure, Figure 1-Figure 4As shown, the dust filter cartridge partition 5 is a solid plate and divides the inner side of the dust filter cartridge 3 into two semicircular cavities. A semicircular opening is provided at the upper position of the rear outer wall of the dust removal shell 1 and at the lower position of the front outer wall of the dust removal shell 1. When in use, the air and dust in the electrical automation equipment will enter the semicircular cavity above the inner side of the dust filter cartridge 3 through the semicircular opening at the upper position of the rear outer wall of the dust removal shell 1. Therefore, the dust filter cartridge 3 can filter and collect the dust. When it is necessary to clean the dust in the dust filter cartridge 3, it is only necessary to rotate the semicircular cavity filled with dust to the bottom, and then the dust in the dust filter cartridge 3 can be cleaned outward through the semicircular opening at the lower position of the front outer wall of the dust removal shell 1.

[0034] In the present disclosure, Figure 3 and Figure 5 As shown, the inner baffle plate 4 is an arc-shaped plate, and the inner baffle plate 4 is in close contact with the outer wall of the lower part of the dust filter cylinder 3, so the semicircular cavity at the lower inner side of the dust filter cylinder 3 can be isolated from the annular cavity inside the dust removal shell 1, so that air can only be sucked inward from the semicircular opening on the outer wall of the rear side of the dust removal shell 1.

[0035] Embodiment 2, based on embodiment 1, as Figure 1-Figure 6 As shown, the positioning plate 7 is a magnet plate, and a magnet plate is also provided on the front side of the dust filter cartridge adjusting handle 6, and the two magnet plates repel each other. There are also two round rods on the rear side of the positioning plate 7. Therefore, after the positioning plate 7 is loosened, the magnet plate on the front side of the dust filter cartridge adjusting handle 6 will push the positioning plate 7 to slide backward, so that the front end of the positioning column 8 can be re-embedded in the round holes on both sides of the positioning plate 7, and the round rods on the rear side of the positioning plate 7 will also contact the outer wall of the dust removal shell 1 to play a limiting role, thereby preventing the positioning plate 7 from sliding too far backward.

[0036] The working principle of this embodiment is as follows: during installation, the dust removal shell 1 can be welded to the outer side of the shell of the electrical automation equipment, and the semicircular opening at the upper position of the outer wall of the rear side of the dust removal shell 1 is connected to the cavity inside the electrical automation equipment, and then the suction pipe 2 is connected to the external suction fan. When in use, the external suction fan can be turned on. When the suction fan is working, the air in the annular cavity between the outer wall of the dust filter cylinder 3 and the inner wall of the dust removal shell 1 will be drawn out through the suction pipe 2. Because at this time the inner baffle plate 4 will be tightly attached to the outer wall of the lower part of the dust filter cylinder 3, the semicircular cavity below the dust filter cylinder partition 5 on the inner side of the dust filter cylinder 3 can be isolated from the annular cavity inside the dust removal shell 1. In this way, air can only be sucked inward from the semicircular opening on the outer wall of the rear side of the dust removal shell 1. At this time, the air in the semicircular cavity above the inner side of the dust filter cylinder 3 will enter the annular cavity inside the dust removal shell 1 through the small holes on the outer wall of the dust filter cylinder 3. At the same time, the air and dust in the electrical automation equipment will pass through the dust removal shell When dust filter cartridge 3 needs to be cleaned, the front end of dust filter cartridge 3 can be put into the circular holes on both sides of dust filter cartridge 3, so that dust filter cartridge 3 can be locked by the positioning plate 7. Then, the dust in dust filter cartridge 3 can be cleaned out through the semicircular opening at the lower position of the outer wall of the dust filter cartridge 1.
