Description

Technical Field

[0001] The invention relates to a mixing device, in particular to a mixing device for catalyst processing, and belongs to the technical field of catalyst processing. Background Art

[0002] The performance of a catalyst depends largely on the uniform distribution of its components. During the mixing process, the active components, carriers and various additives are fully mixed to ensure that each part of the catalyst has a consistent chemical composition and physical structure at the microscopic level. This not only helps to improve the activity of the catalyst and ensure that the chemical reaction can be promoted more efficiently, but also enhances its selectivity, allowing the reaction to proceed in the desired direction and reduce the occurrence of side reactions. Moreover, uniform mixing can improve the stability of the catalyst, extend its service life and reduce production costs.

[0003] In the prior art, for example, the invention with application number 202310886044.8 discloses a polyurethane amine catalyst processing and mixing device and a production process. In order to solve the problem that when there is a large amount of raw materials in the mixing box, when the shaft rotates, all the stirring rods will contact the ingredients at the same time, resulting in a large resistance to stirring, and thus a high-power motor is required to drive it, which is not conducive to saving processing costs. By extending the first cylinder to drive the rotating disk downward, the stirring height can be adjusted, and the ingredients at different positions in the mixing box can be stirred and mixed to achieve sufficient stirring. There is no need to use a high-power motor to stir all the ingredients at the same time, thereby saving the cost of stirring and production equipment.

[0004] Similar to the above application, there are still some shortcomings: During the stirring process, the stirring shaft can only stir in a single direction. Due to the fixed fluid flow pattern, some areas in the container may have dead corners that cannot be stirred, resulting in uneven material mixing. If the raw materials contain agglomerated particles, stirring in a single direction may make it difficult to break up the agglomerates, affecting the mixing effect. In addition, the raw materials cannot be crushed during the feeding process, and the particle size of the mixture is uneven, which will cause stratification due to gravity, also affecting the mixing effect.

[0005] Therefore, a mixing device for catalyst processing is designed to optimize the above problems. Summary of the invention

[0006] The main purpose of the present invention is to provide a mixing device for catalyst processing, which is provided with a stirring mechanism composed of a stirring inner shaft rod, a first stirring blade, a stirring shaft sleeve, a mounting ring, a second stirring blade, and a positioning bolt inside a mixing box, and is used in conjunction with a transmission mechanism composed of a yoke, a first bevel gear, a second bevel gear, a third bevel gear, an incomplete gear, a through hole, a strip rod, a transmission gear, a fixing ring, and a tooth block, and a driving motor. During the stirring process, the device can not only control the first stirring blade and the second stirring blade to rotate in opposite directions at the top and bottom of the mixing box, but also can simultaneously control the first stirring blade and the second stirring blade to revolve in the mixing box during the self-rotation process. In addition, during the revolution process, the rotation directions of the first stirring blade and the second stirring blade are cyclically changed to change the flow direction and path of the raw materials, so that the materials form a complex convection cycle in the container, effectively eliminating the stirring dead angle, and at the same time, the forward and reverse reciprocating The alternating shear force generated by stirring can continuously impact and tear the agglomerates, breaking them into smaller particles, thereby achieving more uniform dispersion, which is of great significance for improving the mixing quality and stability of materials. The pulverizing mechanism composed of a pulverizing box, an outer lining plate, a driving shaft, a conical grinding disc, and a material guide tube can perform pulverizing operations before the raw materials are mixed, thereby improving the functionality of the device. In addition, the rotation of the driving shaft is controlled by a rotating mechanism composed of an annular partition, a driven gear, a rectangular rod, a strip groove, a rack, and a limit rod. The driven gear is connected to the driving shaft, and the stirring shaft sleeve passes through the inside of the strip groove. During the stirring process, the material pulverizing operation can be performed synchronously, which is more energy-efficient.

The reciprocating rotation of the conical grinding disc can crush the material more comprehensively and evenly, making the particle size distribution of the pulverized material more concentrated and the particle size more uniform, thereby improving the mixing effect of subsequent materials.

DETAILED DESCRIPTION

[0020] In order to make the technical solution of the present invention more clear and specific to those skilled in the art, the present invention is further described in detail below in conjunction with embodiments and drawings, but the implementation manner of the present invention is not limited thereto.

[0021] like Figure 1-Figure 8 As shown, this embodiment provides a mixing device for catalyst processing, including a mixing box 1, a stirring mechanism 2 is vertically installed inside the mixing box 1, a driving motor 3 is installed at the middle position of the top of the mixing box 1, a transmission mechanism 4 for controlling the reciprocating rotation of the blades on the stirring mechanism 2 is provided between the output end of the driving motor 3 and the stirring mechanism 2, a crushing mechanism 5 is provided at both ends of the top of the mixing box 1, and a rotating mechanism 6 for driving the crushing mechanism 5 is provided inside the mixing box 1.

[0022] The overall working principle: when in use, first inject the solid granular raw material into the interior of the pulverizing mechanism 5, then start the drive motor 3 to cooperate with the transmission mechanism 4 and the rotating mechanism 6 to provide power for the use of the pulverizing mechanism 5, and pulverize the raw material into uniform particles, and then the particles flow into the interior of the mixing box 1, and then inject the liquid additive into the interior of the mixing box 1, and control the rotation of the stirring mechanism 2 through the transmission mechanism 4, so as to drive the blades at different positions on the stirring mechanism 2 to rotate back and forth to evenly mix the raw materials.

[0023] In this embodiment, the stirring mechanism 2 includes an inner stirring shaft 201, a first stirring blade 202, a stirring shaft sleeve 203, and a second stirring blade 205. The inner stirring shaft 201 is vertically rotatably installed inside the mixing box 1, and the first stirring blade 202 is evenly fixed at the bottom end of the outer side of the inner stirring shaft 201. The stirring shaft sleeve 203 is sleeved on the outside of the inner stirring shaft 201 and is rotatably connected to the inner stirring shaft 201. The second stirring blade 205 is evenly provided at the bottom end of the outer side of the stirring shaft sleeve 203.

[0024] Partial working principle: During the stirring process, the transmission mechanism 4 is used to control the stirring inner shaft 201 and the stirring shaft sleeve 203 to rotate in the opposite direction, so that the first stirring blade 202 and the second stirring blade 205 rotate forward and reverse respectively to quickly stir the material.

[0025] In this embodiment, a mounting ring 204 is vertically slidably installed at the bottom end of the stirring shaft sleeve 203, and the mounting ring 204 is sleeved on the stirring shaft sleeve 203. The end of the second stirring blade 205 is fixedly connected to the outer side of the mounting ring 204. A positioning bolt 206 is installed on the outer side of the mounting ring 204. The positioning bolt 206 passes through the mounting ring 204 and fits with the outer side of the stirring shaft sleeve 203.

[0026] Local working principle: Due to the different amounts of stirring and mixing, the mounting ring 204 can be controlled to slide on the stirring shaft sleeve 203, and the positioning bolt 206 is used to fix the position of the mounting ring 204 to ensure that the second stirring blade 205 is at the inner top of the material, and the first stirring blade 202 is always at the bottom of the material. By rotating and stirring in opposite directions simultaneously above and below the material, the flow direction and path of the material are changed, so that a complex convection cycle is formed in the container, improving the stirring rate and effect of the material.

[0027] In this embodiment, the transmission mechanism 4 includes a U-shaped frame 401, a first bevel gear 402, a second bevel gear 403, a third bevel gear 404 and a forward and reverse reciprocating rotation assembly. The two ends of the U-shaped frame 401 are respectively rotatably connected to the stirring inner shaft 201 and the top end of the stirring shaft sleeve 203. The second bevel gear 403 is rotatably installed inside the U-shaped frame 401. The second bevel gear 403 is fixedly installed on the stirring inner shaft 201. The top end of the stirring shaft sleeve 203 is fixedly installed with a third bevel gear 404. The first bevel gear 402 meshes with the second bevel gear 403 and the third bevel gear 404. The end of the stirring inner shaft 201 extends above the U-shaped frame 401. A forward and reverse reciprocating rotation assembly for controlling the rotation of the stirring inner shaft 201 is provided at the inner top of the mixing tank 1.

[0028] Local working principle: When stirring the material, the forward and reverse reciprocating rotation assembly is used to control the rotation of the stirring inner shaft 201. Since the second bevel gear 403 on the stirring inner shaft 201 meshes with the first bevel gear 402, and the first bevel gear 402 meshes with the third bevel gear 404 at the same time, the stirring inner shaft 201 will rotate in the opposite direction to the stirring shaft sleeve 203, and the first stirring blade 202 and the second stirring blade 205 rotate in opposite directions to stir the material.

[0029] In this embodiment, the forward and reverse reciprocating rotation assembly includes an incomplete gear 405, a through hole 406, a strip-shaped rod 407, a transmission gear 408, a fixed ring 409 and a tooth block 4010. The incomplete gear 405 is fixed at the middle position of the top of the mixing tank 1. A through hole 406 is opened at the middle position of the incomplete gear 405. The output end of the driving motor 3 passes through the through hole 406. The output end of the driving motor 3 is provided with a strip-shaped rod 407. The end of the strip-shaped rod 407 is fixed to the outside of the U-shaped frame 401. The top end of the stirring inner shaft 201 is fixed with a transmission gear 408. A fixed ring 409 is provided on the outside of the inner top of the mixing tank 1. The transmission gear 408 is located between the incomplete gear 405 and the fixed ring 409. Tooth blocks 4010 meshing with the transmission gear 408 are evenly arranged on the inner side of the fixed ring 409. The tooth positions on the incomplete gear 405 and the tooth blocks 4010 are on opposite sides.

[0030] Local working principle: The use of the driving motor 3 will control the rotation of the strip rod 407, and the rotation of the strip rod 407 will drive the inner stirring shaft 201 and the stirring shaft sleeve 203 to rotate circumferentially inside the mixing box 1. When the inner stirring shaft 201 moves, it drives the transmission gear 408 on its top to move, and the transmission gear 408 alternately engages with the tooth block 4010 on the inner side of the fixed ring 409 and the incomplete gear 405. When the tooth block 4010 on the inner side of the fixed ring 409 and the outer side of the incomplete gear 405 move, the transmission gear 408 will rotate in different directions. Therefore, the inner stirring shaft 201 can rotate on its own during the circumferential rotation, and the direction of rotation changes back and forth, thereby the first stirring blade 202 on the inner stirring shaft 201 reciprocates in forward and reverse motion, and the second stirring blade 205 on the stirring shaft sleeve 203 reciprocates in the opposite direction to the first stirring blade 202.

[0031] In this embodiment, the pulverizing mechanism 5 includes a pulverizing box 501, an outer lining plate 502, a driving shaft 503, a conical grinding disc 504 and a material guide pipe 505. The pulverizing box 501 is symmetrically fixed on the top of the mixing box 1. A material guide pipe 505 is provided between the bottom of the pulverizing box 501 and the mixing box 1. The inner wall of the pulverizing box 501 is evenly provided with an outer lining plate 502 along the circumferential direction. A conical grinding disc 504 is provided inside the pulverizing box 501 and between the outer lining plates 502. A driving shaft 503 is rotatably installed at the bottom of the pulverizing box 501. The top end of the driving shaft 503 is fixedly connected to the conical grinding disc 504. The rotating mechanism 6 controls the rotation of the driving shaft 503.

[0032] Partial working principle: After the material is put into the crushing box 501, the rotating mechanism 6 is used to control the driving shaft 503 to rotate, and the conical grinding disc 504 rotates. After the material enters between the conical grinding disc 504 and the outer lining plate 502, the material is ground and crushed.

[0033] In this embodiment, a vertical rod 506 is vertically installed at the middle position of the top of the conical grinding disc 504 , and stirring rods 507 are symmetrically installed on the outer side of the vertical rod 506 .

[0034] Partial working principle: During the crushing process, the vertical rod 506 rotates along with the conical grinding disc 504 , which can prevent the material from clogging the top of the crushing box 501 .

[0035] In this embodiment, a material receiving hopper 7 is provided between the tops of the two groups of crushing boxes 501 , and a conical guide plate 701 is provided at the middle position inside the material receiving hopper 7 .

[0036] Partial working principle: When materials are put in, the receiving hopper 7 is used to receive them, and the use of the conical guide plate 701 can guide the materials toward the inside of the two groups of crushing boxes 501 respectively, so as to reduce the load of a single crushing box 501 and increase the crushing rate.

[0037] In this embodiment, the rotating mechanism 6 includes an annular partition 601, a driven gear 602, a rectangular rod 603, a strip groove 604, a rack 605 and a limit rod 606. The annular partition 601 is horizontally fixed on the inner top of the mixing box 1. The driven gears 602 are rotatably installed on both sides of the top of the annular partition 601. The tops of the driven gears 602 are respectively fixedly connected to the driving shaft 503. The limit rods 606 are symmetrically and vertically installed at the bottom of the fixing ring 409. The bottom ends of the limit rods 606 are horizontally slidably installed with racks 605. The two groups of racks 605 are respectively meshed with the driven gears 602. A rectangular rod 603 is fixed between the two groups of racks 605. The interior of the rectangular rod 603 is provided with a strip groove 604 along the length direction, and the stirring shaft sleeve 203 vertically passes through the interior of the strip groove 604.

[0038] Local working principle: When the stirring shaft sleeve 203 is controlled to rotate circumferentially inside the mixing box 1, since the stirring shaft sleeve 203 passes through the strip groove 604 on the rectangular rod 603, it will apply thrust to the rectangular rod 603, and the rack 605 on the side of the rectangular rod 603 is limited by the limiting rod 606, resulting in the rectangular rod 603 and the rack 605 can only move back and forth in a straight line. During the movement of the rack 605, the driven gear 602 will be controlled to rotate back and forth, thereby driving the conical grinding disc 504 to rotate back and forth for crushing.

[0039] In this embodiment, the outer side of the stirring shaft sleeve 203 is coated with a wear-resistant coating along the circumferential direction at the inner area of ​​the strip groove 604 , and the inner wall of the strip groove 604 is coated with a smooth coating.

[0040] Partial working principle: The wear-resistant coating on the outer side of the stirring shaft sleeve 203 and the smooth coating on the inner wall of the strip groove 604 can reduce the friction resistance during use.
