On the plate 4, a plurality of first through slots 6 are provided on the box body 1 corresponding to the first inclined plate 5, and the first through slots 6 are connected to the space enclosed by the corresponding filter plate 4, the first inclined plate 5 and the box body 1, and a plurality of filter boxes 7 are connected and installed on the box body 1 corresponding to the first through slots 6, and a suction fan 8 is installed on the filter box 7, and a second inclined plate 9 is fixedly installed on the lower side of the inside of the box body 1, and the end of the second inclined plate 9 close to the discharge port 3 is lower than the end away from the discharge port 3, and the end of the second inclined plate 9 close to the discharge port 3 is fixedly connected to the lower side of the inner wall of the discharge port 3. The utility model has a simple structure and an ingenious design. By setting a plurality of inclined filter plates 4, the travel of dust in the box body 1 is extended, so that the dust removal is more complete, which can meet the market demand and is suitable for promotion. When using the utility model, start the suction fan 8, pour the catalyst particles into the box body 1 through the feed port 2, the catalyst particles roll along the uppermost filter plate 4, the suction force generated by the suction fan 8 sucks the dust through the filter plate 4 to the bottom of the filter plate 4, and then sucks it into the filter box 7 through the first through-groove 6, when the catalyst particles roll to the right along the uppermost filter plate 4, they fall onto the middle filter plate 4, and the above process is repeated, finally, the catalyst particles fall from the lowermost filter plate 4 to the second inclined plate 9, and slide out of the box body 1 through the discharge port 3 along the second inclined plate 9, the dust enters the filter box 7 under the action of the suction fan 8, and is adsorbed in sequence by several suction fans 8, so that the dust can be removed more completely.
[0019] Specifically, as shown in the figure, the filter box 7 described in this embodiment includes a filter box body 20, one side of the filter box body 20 is opened and fixedly mounted on the box body 1 corresponding to the first through slot 6, the bottom of the filter box body 20 is provided with a second through slot 21, the bottom of the filter box body 20 is detachably provided with a transverse plate 22, the transverse plate 22 abuts against the bottom of the filter box body 20, two filter screens 23 are fixedly mounted on the transverse plate 22, the front and rear sides and the top side of the filter screen 23 are respectively fitted with the inner wall of the filter box body 20, the side of the filter box body 20 away from the box body 1 is provided with a third through slot 24, and the suction fan 8 is fixedly mounted on the filter box body 20 corresponding to the third through slot 24. The suction fan 8 sucks the dust in the box body 1 into the filter box body 20 through the first through slot 6, and under the action of the two filter screens 23, the dust is deposited on the transverse plate 22 and the filter screen 23, and then the transverse plate 22 and the filter screen 23 are regularly removed from the filter box body 20 to clean the dust.
[0020] Specifically, as shown in the figure, the transverse plate 22 of the present embodiment is provided with through holes 30, and bolts 31 are respectively arranged in the through holes 30.

At this time, the transverse plate 22 can be installed on the filter box body 20.
[0021] Further, as shown in the figure, the filtering accuracy of the filter 23 close to the housing 1 in this embodiment is lower than the filtering accuracy of the filter 23 far from the housing 1. The two filters 23 with different filtering accuracies can gradually filter the dust sucked out from the housing 1, the filter 23 close to the housing 1 can filter out dust with larger particles, and the filter 23 far from the housing 1 can filter out dust with smaller particles.

[0023] Further, as shown in the figure, a flexible cloth 60 is provided on the upper side of the cavity enclosed by the frame 50 and the corresponding center plate 52 in this embodiment, the inner side of the flexible cloth 60 is fixedly connected to the upper side of the outer wall of the corresponding center plate 52, and the outer side of the flexible cloth 60 is fixedly connected to the upper side of the inner wall of the corresponding frame 50. The flexible cloth 60 can prevent catalyst particles from falling through the gap between the frame 50 and the center plate 52.
[0024] Further, as shown in the figure, the driving device described in this embodiment includes a rotating shaft 70, which corresponds to the center plate 52 one by one and is rotatably installed on the housing 1 through a bearing. The outer periphery of the rotating shaft 70 is fixedly installed with a shift lever 71, and the shift lever 71 can be in contact with the corresponding center plate 52. The rear ends of the rotating shaft 70 extend out of the housing 1 and are fixedly installed with a first gear 72. The rear ends of the rotating shaft 70 pass through the reserved holes on the housing 1 and are rotatably installed in the reserved holes through a bearing. The rotating shaft 70 is coaxially arranged with the corresponding first gear 72, and the output shaft of a coaxial motor 73 is fixedly installed on one of the first gears 72. The output shaft of the motor 73 is coaxially arranged with the corresponding first gear 72, and the motor 73 is fixedly installed on the housing 1. The first gear 72 on which the motor 73 is installed is connected to the remaining first gears 72 through a plurality of second gears 74 for transmission, and the second gears 74 are rotatably installed on the housing 1 through bearings. Start the motor 73, and the output shaft of the motor 73 rotates to drive the first gear 72 fixedly connected thereto to rotate. The first gear 72 drives the remaining first gears 72 to rotate through several second gears 74. The first gear 72 drives the corresponding rotating shaft 70 and the lever 71 to rotate. The lever 70 contacts the corresponding center plate 52 and drives the corresponding center plate 52 to move upward. The springs 51 are stretched respectively. As the rotating shaft 70 and the lever 71 continue to rotate, the lever 71 separates from the center plate 52. Under the elastic force of the spring 51 itself, the center plate 52 is reset.
[0025] Furthermore, as shown in the figure, a funnel 80 is fixedly installed on the inner periphery of the feed port 2 in this embodiment, and the funnel 80 is coaxially arranged with the feed port 2. The inner diameter of the upper end of the funnel 80 is larger than the inner diameter of the feed port 2, so it is easier to put catalyst particles into the box 1 through the funnel 80.

Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
