[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1-5As shown, a waste gas treatment device for a ball mill includes a waste gas collection mechanism 1, with a filter mechanism 2 disposed in the middle of the waste gas collection mechanism 1; the filter mechanism 2 includes a support plate 201, with handles 202 fixedly connected to the middle of each side of the support plate 201 in the width direction, and sealing gaskets 203 glued and fixed to the side of the support plate 201 in the length direction; a mounting groove 204 is formed on the top surface of the support plate 201, and a [missing information - likely a type of fixture] is fixedly installed in the middle of the inner side of the mounting groove 204. A shelf 206 is supported and installed on both sides of the partition 205 and the inner wall of the mounting groove 204. The sides of each shelf 206 are fixedly connected to the support plate 201 and the surface of the partition 205 by bolts. A filter screen 207 is fixed to the bottom surface of each shelf 206. The filter screen 207 can be 40-100 mesh and can pre-filter coarse particles. The bottom surface of the filter screen 207 and the bottom surface of the support plate 201 are on the same horizontal plane. Figure 4 As shown, the sealing gaskets in the device are all made of flexible rubber. The sealing gaskets are deformed by compression, thereby reducing the connection gaps on the outside of the support plate 201.

[0026] The exhaust gas collection mechanism 1 includes a collection box 101. The inner wall of the collection box 101 penetrates and supports a support plate 201. Each handle 202 is located on the outer side of the collection box 101. The inner wall surface of the collection box 101 is respectively attached to the surface of the sealing gasket 203. Lifting grooves 110 are provided on the outer surface of the collection box 101, both above and below the support plate 201. Each lifting groove 110 has an internally threaded sleeve 111 fixedly connected to its center. A threaded rod 112 is threaded through and tightly fastened to the center of each internally threaded sleeve 111. One end of the threaded rod 112 is fixedly connected to a knob, and the other end of the threaded rod 112 is rotatably connected to a pressure plate 113. Figure 5 As shown, by rotating the threaded rod 112, the distance between the pressure plates 113 is reduced, thereby achieving the clamping function.

[0027] Each pressure plate 113 has a sealing gasket 114 glued and fixed to the side away from the threaded rod 112. The surface of each sealing gasket 114 is respectively attached to the surface of the support plate 201 and the partition plate 205. The length of the sealing gasket 114 is the same as the width of the support plate 201. The pressure plates 113 are slidably connected along the inner wall of the lifting groove 110. The lower end of the outer wall of the collection box 101 is connected to an exhaust pipe 102. A fan 103 is fixedly installed on the inner wall of the exhaust pipe 102. The inner wall of the collection box 101 is located on the support plate. A collection hood 105 is fixedly installed below the filter screen 207. A guide pipe 106 is fixedly connected to the top surface of the collection hood 105. The top surface of the guide pipe 106 is flush with the bottom surface of the filter screen 207. Return air pipes 107 are fixedly connected to the inner wall of the collection box 101 on both sides of the guide pipe 106. Several air vents 108 are opened on the upper outer wall of the return air pipe 107. A second fan 109 is fixedly connected to the lower end of the return air pipe 107. The exhaust port of the second fan 109 extends to the lower end of the inner wall of the collection box 101. Figure 2 As shown, when the air inlet 108 is under negative pressure, it can absorb the dust falling from the filter screen 207 and the dust drifting out from the gap between the filter screen 207 and the air duct 106, thus preventing a large amount of dust from adhering to the top surface of the air collection hood 105 and reducing the difficulty of cleaning the inside of the collection box 101.

[0028] A baffle 104 is fixedly connected to the lower end of the outer wall of the collection box 101 by screws, and a fan 115 is fixedly installed on the top surface of the collection box 101. Figure 1 As shown, the inside of the collection box 101 can be cleaned after the baffle 104 is removed; the fan structure in the device can be a centrifugal fan or a high-pressure fan, such as the MCJC-1500 model.

[0029] The working principle of this utility model:

[0030] When the device is in use, start the first fan 103 and the third fan 115. The negative pressure at the exhaust pipe 102 port draws the exhaust gas into the collection box 101. The exhaust gas rises into the air hood 105 and is discharged through the air duct 106. During this process, the flue gas passes through the filter screen 207 and is filtered. The filtered flue gas is then discharged to the outside of the collection box 101 by the third fan 115.

[0031] When the filter screen 207 is severely clogged, first start the second fan 109 to draw air out of the return air duct 107, and create negative pressure at the air inlet 108. Then rotate the threaded rod 112. Under the compression of the threaded structure, the threaded rod 112 drives the pressure plate 113 away from the support plate 201. Thus, the operator can pull the handle 202 to move the support plate 201 horizontally. During this process, the dust falling from the surface of the filter screen 207 is absorbed by the air inlet 108, and the dust is discharged along the return air duct 107 to the bottom of the inner wall of the collection box 101.

[0032] After the support plate 201 moves, the unblocked filter 207 is intercepted above the air duct 106. Then, the threaded rod 112 is rotated in the opposite direction, and the pressure plate 113 presses against the surface of the support plate 201 with the help of the sealing gasket 114. At this time, the blocked filter 207 moves to the outside of the collection box 101. The operator can loosen and disassemble the bolts to remove the shelf 206 carrying the filter 207.

[0033] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the present invention should still fall within the patent coverage of the present invention.
