Description

Technical Field

[0001] The invention relates to the technical field of production of alumina catalyst carrier pellets, in particular to a device and method for forming alumina catalyst carrier pellets. Background Art

[0002] Alumina is a commonly used catalyst carrier material, especially in the fields of petroleum refining, chemical production, environmental protection, etc. Alumina carrier beads are widely used due to their good physical and chemical properties. They have the characteristics of high specific surface area, high porosity, good thermal stability, mechanical strength, and acid and alkali resistance.

[0003] Publication number CN221062603U discloses a device for forming alumina catalyst carrier pellets. A motor is fixedly connected to the surface of the toothed chain assembly. A base is fixedly connected to the inner wall of the feed port, located within the socket. A rotating shaft is inserted into the base. A hinge seat is movably connected to the surface of the rotating shaft. Spokes are hingedly connected to the surface of the hinge seat. The ends of the spokes are movably connected to a hinge block. A clamping shaft is fixedly connected to the surface of the hinge block. A dispersion roller is inserted into the socket, and the toothed chain assembly engages to drive the dispersion roller to rotate. The hinge seat is then driven by the rotating shaft to pull the spokes, driving the clamping shaft to secure the end of the dispersion roller. This allows for flexible control of the entire device and enhances its practical performance.

[0004] Although the above application and the prior art can achieve the effect that the feed port of the machine body can be freely disassembled and cleaned when the material is stuck at the installation place of the dispersion roller, after the production of the alumina catalyst carrier pellets is completed, due to the height difference at the material connection point, when the alumina catalyst carrier pellets fall to the material connection point, the alumina catalyst carrier pellets will be broken, thereby affecting its molding effect, and after the production of the alumina catalyst carrier pellets is completed, the surface of the alumina catalyst carrier pellets will contain excess raw material dust, thereby affecting the subsequent packaging effect, and after the excess raw material dust is cleaned, the excess raw material dust will fall to the material connection point, and long-term use will cause the dust at the material connection point to accumulate, thereby affecting its production molding efficiency.

The lifting assembly 3 includes a drive motor 31 fixedly connected to the inside of the drive box 12, the output end of the drive motor 31 is fixedly connected to the drive screw 32, the surface of the drive screw 32 is threadedly connected to the screw plate 321, the inner wall of the processing box 2 is fixedly connected to the first tooth plate 24, and the tilting assembly 4 includes a material receiving box 41 fixedly connected to the top of the screw plate 321;

[0053] The shaking assembly 5 is provided inside the processing box 2 and is used to shake the alumina catalyst carrier pellets to remove excess raw materials on the surface of the alumina catalyst carrier pellets;

[0054] The cleaning component 6 is provided inside the processing box 2 and is used to clean the excess raw materials on the surface of the alumina catalyst support pellets, thereby preventing the excess raw materials from accumulating;

[0055] It should be noted that the screw plate 321 is slidably connected to the interior of the vertical slot 23;

[0056] 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 preventing the alumina catalyst carrier pellets from being damaged due to the existence of the height difference;

[0057] For specific embodiment 2, please refer to Figures 1 to 6 According to a molding device provided in the first embodiment, this embodiment provides a further technical solution:

[0058] The interior of the receiving box 41 is fixedly connected to an inclined block 411, and the interior of the receiving box 41 is rotatably connected to a rotating rod 42. Both ends of the rotating rod 42 are fixedly connected to a rotating gear 421. The surface of the rotating rod 42 is fixedly connected to a blocking plate 422. The rotating gear 421 is meshed with the first tooth plate 24 for transmission. The rocking assembly 5 includes a fixed cylinder 51 fixedly connected to the interior of the moving groove 22, the interior of the fixed cylinder 51 is fixedly connected to a spring 511, and the interior of the fixed cylinder 51 is slidably connected to 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 to a slider 513, and one end of the slider 513 is fixedly connected to the rocking plate 52.

[0059] It should be noted that the rotating gear 421 is always in meshing with the first tooth plate 24, and a retractable inclined plate is provided inside the inclined block 411 to prevent the alumina catalyst carrier pellets 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. In addition, the blocking plate 422 can push the retractable inclined plate into the interior of the inclined block 411 during the rotation process.

[0060] 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 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. In the process of the material receiving box 41 descending, the first gear 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 causing the alumina catalyst carrier pellets to roll to the top of the shaking plate 52 through the inclined block 411 and the blocking plate 422, thereby avoiding the situation where the alumina catalyst carrier pellets are broken due to the height difference;

[0061] For specific example three, 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:

[0062] 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, and an oblique bar 524 is fixedly connected to one end of the shaking plate 52. The shaking assembly 5 also includes a driving 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. The surface of the worm 54 and the outside of the processing box 2 are fixedly connected to a driven bevel gear 541, and the driving 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, and the surface of the rotating rod 55 is fixedly connected to a worm gear 551 and a cam 552, and the worm gear 551 is meshed for transmission with the worm 54;

[0063] 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. The diameter of the opening 521 is smaller than the diameter of the alumina catalyst carrier pellets, so the alumina catalyst carrier pellets will not fall from the opening 521. A through groove is provided 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, so that the processed alumina catalyst carrier pellets are moved 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 a tilted state inside the processing box 2;

[0064] 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 32, and the driving screw 32 synchronously drives the active bevel gear 53 to rotate, so that the driven bevel gear 541 drives the worm gear 551 to rotate through the worm 54, thereby causing the cam 552 to drive 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, thereby squeezing or stretching the spring 511. 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, thereby driving the shaking plate 52 to shake, causing the alumina catalyst carrier pellets on the top of the shaking plate 52 to shake, thereby causing the excess raw material dust on the surface of the alumina catalyst carrier pellets to fall off by shaking, and then fall to the top of the dust collecting plate 21 through the opening 521, thereby avoiding affecting the subsequent packaging effect due to the dust on its surface;

[0065] For specific example 4, please refer to Figures 1 to 12 According to the alumina catalyst carrier pellet forming device provided in the third specific embodiment, this embodiment provides a further technical solution:

[0066] 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. The driven gear plate 62 is meshed with the driving gear 61 for transmission. One end of the driven gear plate 62 is fixedly connected to a cleaning strip 621.

[0067] It should be noted that an inclined plate is fixedly connected to the top of the cleaning strip 621. 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 gear plate 62 is in sliding contact with one end of the processing box 2.

[0068] 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 interior 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;

[0069] Specific embodiment 5, the present invention also provides a method for forming alumina catalyst carrier pellets, the carrier pellet forming method specifically comprising the following steps:

[0070] Step 1: The alumina catalyst carrier pellets produced by the granulator 1 are discharged into the processing box 2 through the discharge port 11;

[0071] Step 2: When the produced alumina catalyst support pellets need to be connected, the lifting assembly 3 is started to drive the tilting assembly 4 to rise, and then the pellets are connected;

[0072] Step 3: When the tilting assembly 4 moves to the bottom, the tilting assembly 4 opens, causing the alumina catalyst carrier balls to roll to the top of the shaking assembly 5. When the lifting assembly 3 operates, the shaking assembly 5 shakes them;

[0073] Step 4: During the operation of the shaking component 5, excess raw materials on the surface of the alumina catalyst carrier balls fall into the interior of the processing box 2. The shaking component 5 drives the cleaning component 6 to clean and collect excess raw materials inside the processing box 2.

[0074] 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 connected, 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 connected, 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 321 to drive the drive plate 321 to drive the receiving box 4 ... The screw 32 is reversed, driving the screw 32 to drive the screw plate 321 to descend, so that the screw plate 321 drives the material receiving box 41 to descend. In the process of the material receiving box 41 descending, 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 rocking plate 52, thereby causing the alumina catalyst carrier pellets to roll to the top of the rocking plate 52 through the inclined block 411 and the blocking plate 422, thereby avoiding the situation where the alumina catalyst carrier pellets are 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 pellets, the driving motor 31 drives the In the process of the screw plate 321 rising up driven by the screw 32, the driving screw 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 shape 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 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 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, thereby causing the dust to fall into 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.
