The specific working principle is as follows: after the calcining furnace 1 finishes calcining the catalyst, the catalyst is poured into the storage box 25, then the first driving member 21 is started to drive the first telescopic rod 22 to extend, and further drive the first transportation block 23 and the second transportation block 24 to move towards the support belt 201, so that the second transportation block 24 extrudes the support belt 201, and further drive the support belt 201 to move to the fixing buckle 26 by the second transportation block 24 and the fixing buckle 26, and fix the extruded support belt 201 by the second transportation block 24 and the fixing buckle 26, and simultaneously drive the two first fixing rollers 27 to approach each other when the support belt 201 is extruded, so that the slope of the inclined part at the upper part of the support belt 201 is reduced, and then the first telescopic rod 22 is continuously extended to cause the third telescopic rod 202 to contract, so that the first rotating plate 205 and the second rotating plate 206 rotate, and drive the fixing plate 204 to move upwards, so that the fixing plate 204 drives the storage box 25 to move upwards, the storage box 25 and the catalyst inside the storage box are moved upwards to a designated position, and meanwhile, in the process that the storage box 25 is lifted to a designated height, the rotating cover plate 208 can be opened through the first connecting line 209, so that the catalyst can slide down through the opened rotating cover plate 208, and the catalyst inside the storage box 25 can slide down onto the support belt 201; meanwhile, before the catalyst in the storage box 25 is moved onto the support belt 201, if the gradient of the support belt 201 needs to be adjusted, the slide rail 32 can be started to drive the slide block 33 to move, so that the slide block 33 drives the fixing buckle 26 to move, and further the fixing buckle 26 drives the two first fixing rollers 27 to change the supporting position of the support belt 201, so that the gradient of the upper part of the support belt 201 is changed, and the gradient of the upper part of the support belt 201 can be adapted to different particle sizes of the catalyst; when all the catalyst in the storage box 25 moves onto the support belt 201 and resets the second transport block 24, extending the fourth telescopic rod 34 to drive the stabbing buckle 38 to move and drive the support belt 201 to reset, and after the support belt 204 is completely reset, retracting the fourth telescopic rod 34 to enable the stabbing buckle 38 to rotate through the rotating shaft 36 to reset and move to the initial position under the driving of the retraction of the fourth telescopic rod 34; meanwhile, when the catalyst slides to the position of the material sieving port 41, the second driving part 401 is started to drive the fifth telescopic rod 404 to extend, so that the fifth telescopic rod 404 pushes the second connecting rod 49 to rotate relative to the fixed seat 47, the third connecting rod 40 drives the first connecting rod 48 to synchronously rotate with the second connecting rod 49, the first connecting rod 48 and the second connecting rod 49 further synchronously drive the moving plate 46 to move, so that the moving plate 46 drives the first sieve plates 44 to move, the space between the first sieve plates 44 is reduced through the movement of the two first sieve plates 44 at the two sides, and the space between the second sieve plates 45 is changed through the same operation steps, so that the material sieving port 41 can carry out material sieving operations with different particle sizes as required, and the catalysts in different batches can be conveniently sieved; after the catalyst is screened by the screening device 4, the screened catalyst falls into the blanking box 43 and is conveyed away by the conveyor belt 42, and the calcination screening process of the catalyst is completed.
