Description

Technical Field

[0001] This utility model relates to the field of abrasive technology, specifically to a device for uniformly mixing powder raw materials. Background Technology

[0002] Abrasives are sharp, hard materials used to grind the surfaces of softer materials. Abrasives are broadly classified into natural and synthetic abrasives. They are also categorized by hardness into superhard and ordinary abrasives. The range of abrasives is vast, from soft household detergents and gemstone abrasives to the hardest material, diamond. Abrasives are essential materials in the manufacture of every precision product. Many natural abrasives have been replaced by synthetic abrasives.

[0003] The utility model patent with patent number CN218281379U relates to the field of activated alumina technology, and more particularly to a mixing and preparation device for activated alumina processing. Its technical solution includes: a mixing tank, a retainer, and a spiral conveyor rod. A motor is embedded in the retainer, and a bearing is embedded in the top of the mixing tank below the retainer. A movable rod is rotatably mounted on the bearing. This utility model has the advantage of using the spiral conveyor rod to stir the raw materials inside the discharge pipe during discharge, thereby accelerating the discharge speed and preventing blockage inside the discharge pipe.

[0004] In the production of abrasive powder, a mixing device is required to uniformly mix the raw materials. Although the mixing device in the aforementioned patent avoids material discharge blockage, the raw materials need to be crushed and ground before mixing, which reduces the mixing efficiency of the raw materials. To address this issue, we provide a uniform mixing device for powder raw materials. Utility Model Content

[0005] The purpose of this invention is to provide a device for uniformly mixing powder raw materials to solve the problems raised in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a uniform mixing device for powder raw materials, including a mixing barrel, a power shaft rotatably connected inside the mixing barrel, a grinding mechanism provided at the top of the mixing barrel, the grinding mechanism including a first grinding disc and a sieve plate fixedly connected to the mixing barrel, a second grinding disc adapted to the first grinding disc fixedly connected to the top of the power shaft, a mixing mechanism provided inside the mixing barrel, the mixing mechanism including a tumbling paddle and a scraping rod, and the scraping rod being slidably connected to the inside of the mixing barrel.

[0007] Preferably, the top of the mixing tank is fixedly connected to a feed inlet, and the bottom of the mixing tank is fixedly connected to a motor, with the output end of the motor fixedly connected to a power shaft. Through the feed inlet, the abrasive raw material is transported to the middle of the second grinding disc, thereby improving the efficiency of the second grinding disc in grinding the raw material.

[0008] Preferably, a cleaning rod is fixedly connected to the surface of the power shaft, and the cleaning rod is slidably connected to the sieve plate. Grinding teeth are fixedly connected to the surfaces of the first and second grinding discs. The cleaning rod can quickly screen the powder on the surface of the sieve plate and push large particles of material to the outside, thereby improving the screening efficiency of powder raw materials.

[0009] Preferably, a sliding hopper is fixedly connected inside the mixing barrel, and the sliding hopper is located between the second grinding disc and the sieve plate. The surface of the sieve plate is fixedly connected to a coarse material outlet. Through the coarse material outlet, large particles of raw material pushed out by the cleaning rod are discharged from the mixing barrel, which facilitates secondary grinding of the raw materials.

[0010] Preferably, a connecting rod is fixedly connected to the surface of the power shaft, and the connecting rod is fixedly connected to the scraping rod. A stirring blade is fixedly connected to the surface of the power shaft. The stirring blade is driven to rotate by the power shaft to stir and mix the powder raw materials inside the mixing tank, thereby improving the uniform mixing effect of the powder raw materials.

[0011] Preferably, the bottom of the mixing tank is fixedly connected to a discharge pipe, and the top of the discharge pipe is slidably connected to a sealing plate. The sealing plate controls the closing and connection of the discharge pipe, thereby controlling whether the powder raw material is discharged.

[0012] Preferably, an electric push rod is fixedly connected to the surface of the mixing tank, and the output end of the electric push rod is fixedly connected to the sealing plate. The electric push rod controls the movement of the sealing plate and controls the closing and connection of the discharge pipe.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This application uses a power shaft to drive the second grinding disc to rotate. The second grinding disc is adapted to the first grinding disc to grind and crush the abrasive raw materials, reducing the difficulty of mixing. The crushed raw materials are screened by a sieve plate to remove large particles, improving the mixing effect of the raw material powder and making the powder raw materials more uniform. The rotating tumbling slurry causes the raw materials inside the mixing barrel to turn upward, improving the mixing effect of the raw materials. The scraper prevents the powder raw materials from sticking to the inner wall of the mixing barrel, reducing the damage of powder particles to the mixing barrel and increasing the service life of the mixing barrel.

[0015] 2. This application uses the feed inlet to transport abrasive raw materials to the surface of the second grinding disc, improving the grinding efficiency of the second grinding disc. The motor controls the rotation of the power shaft, improving the stability of the internal device operation of the mixing tank. The cleaning rod quickly screens the powder on the sieve plate surface and pushes large particles to the outside, improving the powder screening efficiency. The grinding teeth improve the grinding efficiency of the first and second grinding discs. The hopper transports the ground powder raw materials to the middle of the sieve plate, improving powder screening efficiency. The coarse material outlet discharges large particles pushed out by the cleaning rod from the mixing tank, facilitating secondary grinding of the raw materials and improving the grinding effect of the powder raw materials.

[0016] 3. This application uses a connecting rod to fix the scraper rod and the power shaft together. The rotation of the power shaft causes the connecting rod to drive the scraper rod to rotate, which in turn drives the stirring blade to rotate, thus stirring and mixing the powder raw materials inside the mixing tank, improving the uniformity of the powder raw materials. The discharge pipe facilitates the discharge of the mixed powder raw materials from the mixing tank. The sealing plate controls the closure and connection of the discharge pipe, thereby controlling whether the powder raw materials are discharged. The electric push rod controls the movement of the sealing plate, controlling the closure and connection of the discharge pipe. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1-5 As shown, this utility model provides a technical solution for a uniform mixing device for powder raw materials, including a mixing barrel 1, a power shaft 3 rotatably connected inside the mixing barrel 1, a feed inlet 2 fixedly connected to the top of the mixing barrel 1, and a motor 4 fixedly connected to the bottom of the mixing barrel 1. The output end of the motor 4 is fixedly connected to the power shaft 3. Through the feed inlet 2, the abrasive raw materials are transported to the surface of the second grinding disc 502, thereby improving the efficiency of the second grinding disc 502 in grinding the raw materials. The rotation of the power shaft 3 is controlled by the motor 4, thereby improving the stability of the internal device operation of the mixing barrel 1.

[0025] A grinding mechanism 5 is provided at the top of the mixing tank 1. The grinding mechanism 5 includes a first grinding disc 501 and a sieve plate 505 fixedly connected to the mixing tank 1. A second grinding disc 502 adapted to the first grinding disc 501 is fixedly connected to the top of the power shaft 3. The second grinding disc 502 is rotated by the power shaft 3. The abrasive raw materials are ground and crushed by the second grinding disc 502 and the first grinding disc 501, and the raw materials are ground into a fine powder state to reduce the difficulty of mixing. The crushed raw materials are screened by the sieve plate 505 to screen out the large particles of raw materials, improve the mixing effect of raw material powder, and make the powder raw materials more uniform.

[0026] Grinding teeth 503 are fixedly connected to the surfaces of the first grinding disc 501 and the second grinding disc 502. The grinding teeth 503 improve the efficiency of grinding abrasive raw materials by the first grinding disc 501 and the second grinding disc 502.

[0027] A cleaning rod 506 is fixedly connected to the surface of the power shaft 3, and the cleaning rod 506 is slidably connected to the sieve plate 505. The cleaning rod 506 quickly screens the powder on the surface of the sieve plate 505 and pushes large particles of material to the outside, thereby improving the screening efficiency of powder raw materials.

[0028] A sliding hopper 504 is fixedly connected inside the mixing tank 1, and the sliding hopper 504 is located between the second grinding disc 502 and the sieve plate 505. The surface of the sieve plate 505 is fixedly connected to a coarse material outlet 507. The ground powder raw material is transported to the middle of the sieve plate 505 through the sliding hopper 504 to improve the efficiency of powder screening. Large particles of raw material pushed out by the cleaning rod 506 are discharged from the mixing tank 1 through the coarse material outlet 507, which facilitates secondary grinding of the raw material and improves the grinding effect of the powder raw material.

[0029] The mixing tank 1 is equipped with a mixing mechanism 6, which includes a tumbling paddle 601 and a scraper 604. The scraper 604 is slidably connected to the inside of the mixing tank 1. By rotating the tumbling paddle 601, the raw materials inside the mixing tank 1 are turned upward, which improves the mixing effect of the raw materials. By using the scraper 604, the powder raw materials are prevented from sticking to the inner wall of the mixing tank 1, reducing the damage of powder particles to the mixing tank 1 and improving the service life of the mixing tank 1.

[0030] A connecting rod 603 is fixedly connected to the surface of the power shaft 3, and the connecting rod 603 is fixedly connected to the scraper 604. A stirring blade 602 is fixedly connected to the surface of the power shaft 3. The scraper 604 is fixed to the power shaft 3 through the connecting rod 603. When the power shaft 3 rotates, the connecting rod 603 drives the scraper 604 to rotate. The stirring blade 602 is driven to rotate through the power shaft 3, so as to stir and mix the powder raw materials inside the mixing tank 1, thereby improving the uniform mixing effect of the powder raw materials.

[0031] The bottom of the mixing tank 1 is fixedly connected to a discharge pipe 605, and the top of the discharge pipe 605 is slidably connected to a sealing plate 606. The powder raw materials that have been mixed in the mixing tank 1 can be discharged through the discharge pipe 605. The sealing plate 606 controls the closing and opening of the discharge pipe 605, thereby controlling whether the powder raw materials are discharged.

[0032] An electric push rod 607 is fixedly connected to the surface of the mixing tank 1, and the output end of the electric push rod 607 is fixedly connected to the sealing plate 606. The electric push rod 607 controls the movement of the sealing plate 606 and controls the closing and connection of the discharge pipe 605.

[0033] The electric motor 4 and the electric actuator 607 are existing technologies, and their detailed parameters and models will not be described in detail in this application.

[0034] In use, this invention works as follows: Abrasive raw materials are fed onto the surface of the second grinding disc 502 through the feed inlet 2. The motor 4 controls the rotation of the power shaft 3, which in turn drives the second grinding disc 502 to rotate. The second grinding disc 502, in conjunction with the first grinding disc 501, grinds and pulverizes the abrasive raw materials. The ground powder is then conveyed to the center of the sieve plate 505 via the sliding hopper 504. The cleaning rod 506 quickly filters the powder from the surface of the sieve plate 505, pushing large particles to the outside. The large particles pushed out by the cleaning rod 506 are discharged from the mixing tank 1 through the coarse material outlet 507, facilitating secondary processing of the raw materials. The powder screened by the grinding and sieving plate 505 falls to the bottom of the mixing tank 1. The tumbling paddle 601 is rotated by the power shaft 3, causing the raw materials inside the mixing tank 1 to surge upwards. The scraping rod 604 is rotated by the connecting rod 603 to scrape the powder off the inner wall of the mixing tank 1. The stirring blade 602 is rotated by the power shaft 3 to stir and mix the powder raw materials inside the mixing tank 1, making the abrasive powder raw materials more uniform and improving the mixing effect of the raw materials. After the powder is mixed, the sealing plate 606 is moved by the electric push rod 607 to connect the discharge pipe 605, so that the mixed powder raw materials in the mixing tank 1 can be discharged through the discharge pipe 605.

[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
