The shaking component 5 includes a fixed cylinder 51 fixedly connected to the inside of the moving groove 22, and the inside of the fixed cylinder 51 is fixedly connected with a spring 511, and the inside of the fixed cylinder 51 is slidably connected with an extension cylinder 512, one end of the extension cylinder 512 is fixedly connected to one end of the spring 511, and the end of the extension cylinder 512 away from the spring 511 is fixedly connected with a slider 513, and one end of the slider 513 is fixedly connected to the shaking plate 52; It should be noted that the rotating gear 421 is always in meshing with the first tooth plate 24, and a telescopic inclined plate is provided inside the inclined block 411, so as to prevent the alumina catalyst carrier ball from being stuck between the inclined block 411 and the blocking plate 422 during the process of moving from the inclined block 411 to the blocking plate 422, and the blocking plate 422 can push the telescopic inclined plate to the inside of the inclined block 411 during the rotation process; When it is necessary to place the alumina catalyst carrier pellets on the top of the shaking plate 52, the drive motor 31 is started through the control panel 13, so that the drive motor 31 drives the drive screw 32 to reverse, and the drive screw 32 drives the screw plate 321 to descend, so that the screw plate 321 drives the material receiving box 41 to descend. During the descent of the material receiving box 41, the first tooth plate 24 drives the rotating rod 42 to rotate by rotating the gear 421, so that the rotating rod 42 drives the blocking plate 422 to rotate, and the blocking plate 422 rotates to the top of the shaking plate 52, thereby making the alumina catalyst carrier pellets roll to the top of the shaking plate 52 through the inclined block 411 and the blocking plate 422, thereby avoiding the occurrence of the alumina catalyst carrier pellets being broken due to the height difference; For specific embodiment 3, please refer to Figures 1 to 12 According to the alumina catalyst carrier pellet forming device provided in the second specific embodiment, this embodiment provides a further technical solution: A plurality of openings 521 are provided on the top of the shaking plate 52, a U-shaped frame 522 is fixedly connected to the top of the shaking plate 52, a striking block 523 is fixedly connected to the bottom of the shaking plate 52, an oblique bar 524 is fixedly connected to one end of the shaking plate 52, the shaking assembly 5 also includes an active bevel gear 53 fixedly connected to the surface of the driving screw 32 and a worm 54 rotatably connected to the inside of the processing box 2, a driven bevel gear 541 is fixedly connected to the surface of the worm 54 and located on the outside of the processing box 2, the active bevel gear 53 and the driven bevel gear 541 are meshed for transmission, the shaking assembly 5 also includes a rotating rod 55 rotatably connected to the top of the dust collecting plate 21, a worm wheel 551 and a cam 552 are fixedly connected to the surface of the rotating rod 55, and the worm wheel 551 and the worm 54 are meshed for transmission; It should be noted that the striking block 523 and the cam 552 are squeezed and matched with each other, and the shaking plate 52 will not contact the inner wall of the processing box 2 during the shaking process, thereby avoiding damage to the processing box 2 due to the collision of the shaking plate 52.

A through groove is opened on one side of the processing box 2, and a baffle is fixedly connected to the bottom of the screw plate 321. When the screw plate 321 rises, the baffle opens the through groove to move the treated alumina catalyst carrier pellets out of the through groove, thereby avoiding the alumina catalyst carrier pellets from being accumulated on the top of the shaking plate 52, and the shaking plate 52 is in an inclined state inside the processing box 2; When it is necessary to clean the excess raw material dust on the surface of the alumina catalyst carrier pellets, the driving motor 31 drives the screw plate 321 to rise by driving the screw rod 32, and the driving screw rod 32 synchronously drives the active bevel gear 53 to rotate, so that the driven bevel gear 541 drives the worm wheel 551 to rotate through the worm 54, and then the cam 552 drives the shaking plate 52 to move through the striking block 523, and the shaking plate 52 squeezes or stretches the extension tube 512 through the slider 513, so that the spring 511 is squeezed or stretched. When the cam 552 is no longer in contact with the striking block 523, the spring 511 returns to its original state due to not being squeezed or stretched by the extension tube 512, and then drives the shaking plate 52 to shake, so that the alumina catalyst carrier pellets on the top of the shaking plate 52 are shaken, and then the excess raw material dust on the surface of the alumina catalyst carrier pellets falls off through the shaking, and then falls to the top of the dust collecting plate 21 through the opening 521, so as to avoid the subsequent packaging effect being affected by the dust on its surface; For specific example 4, please refer to Figures 1 to 12 According to the alumina catalyst carrier pellet forming device provided in the specific embodiment 3, this embodiment provides a further technical solution: The cleaning assembly 6 includes a driving gear 61 fixedly connected to the surface of the rotating rod 55 and a driven gear plate 62 slidably connected to the top of the dust collecting plate 21.

It should be noted that the top of the cleaning strip 621 is fixedly connected with an inclined plate, and the setting of the inclined plate can effectively prevent the raw material dust from accumulating on the top of the cleaning strip 621, and the end of the cleaning strip 621 away from the driven tooth plate 62 is in sliding contact with one end of the processing box 2; When it is necessary to clean the raw material dust on the top of the dust collecting plate 21, the rotating rod 55 drives the cam 552 to rotate, and the rotating rod 55 synchronously drives the driving gear 61 to rotate, so that the driving gear 61 drives the driven gear plate 62 to move, and the driven gear plate 62 drives the cleaning bar 621 to move on the top of the dust collecting plate 21, so that the dust falls into the inside of the dust collecting box 25 through the dust collecting groove 211, thereby preventing the dust from being accumulated on the top of the dust collecting plate 21 and affecting its use efficiency; Specific embodiment 5, the present invention also provides a method for forming alumina catalyst carrier pellets, and the method for forming alumina catalyst carrier pellets specifically comprises the following steps: Step 1: The alumina catalyst carrier pellets produced by the granulator 1 are discharged into the processing box 2 through the discharge port 11; Step 2: When the produced alumina catalyst carrier pellets need to be connected, the lifting component 3 is started to drive the tilting component 4 to rise, and then the pellets are connected; Step 3, when the tilting assembly 4 moves to the bottom, the tilting assembly 4 is opened, so that the alumina catalyst carrier ball rolls to the top of the shaking assembly 5, and when the lifting assembly 3 is in operation, the shaking assembly 5 shakes it; Step 4. During the operation of the shaking component 5, excess raw materials on the surface of the alumina catalyst carrier beads fall into the interior of the processing box 2. The cleaning component 6 is driven by the shaking component 5 to clean and collect excess raw materials inside the processing box 2.

[0025] Working principle: When in use, the alumina catalyst carrier pellets are produced by the granulator 1. When the alumina catalyst carrier pellets need to be received, the drive motor 31 is started through the control panel 13. The drive motor 31 drives the screw plate 321 to rise by driving the screw rod 32, so that the screw plate 321 drives the receiving box 41 to rise to the bottom of the discharge port 11, and then the alumina catalyst carrier pellets are received, thereby avoiding the alumina catalyst carrier pellets from being damaged due to the existence of the height difference. When the alumina catalyst carrier pellets need to be placed on the top of the shaking plate 52, the drive motor 31 is started through the control panel 13, so that the drive motor 31 drives the drive motor 31 to drive the drive plate 32 ... The screw rod 32 is reversed, driving the screw rod 32 to drive the screw plate 321 to descend, so that the screw plate 321 drives the material receiving box 41 to descend. During the descending process of the material receiving box 41, the first tooth plate 24 drives the rotating rod 42 to rotate by rotating the gear 421, so that the rotating rod 42 drives the blocking plate 422 to rotate, so that the blocking plate 422 rotates to the top of the shaking plate 52, thereby making the alumina catalyst carrier ball roll to the top of the shaking plate 52 through the inclined block 411 and the blocking plate 422, thereby avoiding the situation that the alumina catalyst carrier ball is broken due to the height difference. When it is necessary to clean the excess raw material dust on the surface of the alumina catalyst carrier ball, the driving motor 31 drives In the process of the screw plate 321 being driven upward by the screw rod 32, the driving screw rod 32 synchronously drives the active bevel gear 53 to rotate, so that the driven bevel gear 541 drives the worm wheel 551 to rotate through the worm rod 54, and then the cam 552 drives the shaking plate 52 to move through the striking block 523, and the shaking plate 52 squeezes or stretches the extension tube 512 through the slider 513, so that the spring 511 is squeezed or stretched. When the cam 552 is no longer in contact with the striking block 523, the spring 511 is restored to its original state due to not being squeezed or stretched by the extension tube 512, and then drives the shaking plate 52 to shake, so that the alumina catalyst carrier ball on the top of the shaking plate 52 shakes, thereby causing the alumina catalyst to move. The excess raw material dust on the surface of the chemical carrier ball falls off by shaking, and then falls to the top of the dust collecting plate 21 through the opening 521, thereby avoiding the dust on its surface from affecting the subsequent packaging effect. When the raw material dust on the top of the dust collecting plate 21 needs to be cleaned, the rotating rod 55 drives the cam 552 to rotate, and the rotating rod 55 synchronously drives the driving gear 61 to rotate, so that the driving gear 61 drives the driven gear plate 62 to move, and the driven gear plate 62 drives the cleaning bar 621 to move on the top of the dust collecting plate 21, so that the dust falls to the inside of the dust collecting box 25 through the dust collecting groove 211, thereby avoiding the dust from accumulating on the top of the dust collecting plate 21 and affecting its use efficiency.
