DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0021] Referring to Figures 1-4 , a highly efficient dust removal device for powder coating processing, including a vertically arranged square tube 1 for circulating waste gas and air. The square tube 1 is made of metal and is used to support the switching plate 2. Protective nets 14 made of metal are fixedly embedded near the upper and lower edges inside the square tube 1 to prevent larger sundries from entering the square tube 1. Three horizontally arranged switching plates 2 are slidably inserted into the square tube 1 from top to bottom to switch the positions of the two grooves. Openings corresponding to the switching plates 2 are provided on both inner sides of the square tube 1. A first rubber pad 10 is fixedly connected to the inner side wall of the opening to improve the sealing performance between the switching plate 2 and the opening. The two ends of the switching plate 2 respectively slide through the opening and are fixedly connected to a vertically arranged pull plate 3 to drive the switching plate 2 to move;

[0022] In this embodiment, a first magnet 4 is fixedly connected to the side of the pull plate 3 close to the square tube 1 to cooperate with the second magnet 11 to attract each other and prevent the pull plate 3 from loosening when not pulled by the user. Slots corresponding to the first magnet 4 are provided on both sides of the square tube 1. A second magnet 11 that attracts the first magnet 4 is fixedly connected to the inner side wall of the slot. A pull ring 9 is fixedly connected to the side of the pull plate 3 away from the square tube 1 to facilitate the user to pull the pull plate 3. A second rubber pad 13 is fixedly connected to the inner side wall of the pull ring 9 to improve the comfort of using the pull ring 9;

[0023] In this embodiment, grooves are provided at the upper ends of the switching plate 2 near the left and right edges. A through hole is provided at the inner bottom of the groove. Filtering mechanisms are provided in the grooves of the three switching plates 2 to filter waste gas and air. The three filtering mechanisms are, from top to bottom, an activated carbon filter screen 6, a HEPA filter screen 7, and a primary filter screen 8, which are used to filter waste gas and air multiple times to achieve the purpose of dust removal. A limiting ring 5 is provided at the upper end of the filtering mechanism to prevent the filtering mechanism from loosening. The limiting ring 5 is threadedly connected to the placement groove. A vertically arranged handle 12 is fixedly connected to the upper end of the limiting ring 5 to facilitate the user to manually rotate the limiting ring 5.

[0024] In this embodiment, first, the upper end of the square tube 1 is connected to an external air suction device (fan). The waste gas is sucked into the square tube 1 by the air suction device and discharged outwards. When passing through the square tube 1, the waste gas will pass through the through holes and grooves, and when passing through the through holes and grooves, it will be filtered through the primary filter 8, HEPA filter 7 and activated carbon filter 6 in sequence, so as to perform dust removal and filtration operations on the waste gas. When maintenance and repair of the primary filter 8, HEPA filter 7 and activated carbon filter 6 are required, since two grooves are provided on each switching plate 2 (each groove is provided with a filtering mechanism, namely the primary filter 8, HEPA filter 7 and activated carbon filter 6), manually pull the pull ring 9 to drive the pull plate 3 to move, drive the switching plate 2 to move through the pull plate 3, and move another groove (the groove outside the square tube 1) to the inside of the square tube 1 through the movement of the switching plate 2 to continue the filtering operation. And the groove that was originally inside the square tube 1 will move outwards from the inside of the square tube 1 as the switching plate 2 moves. At this time, it is convenient for the user to maintain and clean the filtering mechanism in the groove. At the same time, manually rotate the handle 12 to drive the limit ring 5 to rotate, and screw the limit ring 5 out of the groove, then the filtering mechanism can be taken out for replacement operation.

[0025] As mentioned above, the activated carbon filter, HEPA filter and primary filter are existing mature technologies, and their working principles and internal structures are known to those skilled in the art. This application only utilizes their functions and does not improve their internal structures. Therefore, no detailed description is given.

[0026] As mentioned above, the above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent replacements or changes, and all should be covered within the protection scope of the present invention.
