Description

Technical Field

[0001] This utility model relates to the field of mixer technology, specifically a mixer for refractory materials. Background Technology

[0002] Materials whose physical and chemical properties allow them to be used in high-temperature environments are called refractory materials. Refractory materials are usually processed into products of specific shapes for use, such as refractory bricks. Before making refractory bricks, the raw materials and binders of the refractory materials need to be mixed evenly to ensure the refractory performance of the refractory bricks.

[0003] A search revealed a Chinese patent with publication number CN216879191U, which discloses a refractory material mixer. The aim is to solve the problem of material clogging caused by insufficient mixing of materials deposited at the bottom of the tank during the use of existing mixers. To this end, the refractory material mixer of this invention includes a tank and a discharge hopper. The bottom of the tank is connected to the discharge hopper, and a feeding assembly is installed at the bottom of the discharge hopper. The inner cavity of the shell is connected to the discharge hopper. A support plate is sleeved inside the shell, and a cylinder is fixedly connected inside the support plate. A top rod is sleeved inside the cylinder, and the bottom end of the top rod passes through the cylinder and is fixedly connected to a retaining ring. An elastic element is sleeved on the outer wall of the top rod, with one end of the elastic element fitting against the cylinder and the other end fitting against the retaining ring. By activating a telescopic component, the retaining ring is pushed upwards in the cylinder, causing the retaining ring to move the top rod and the top block. The top block then reciprocates within the shell, preventing the raw materials in the shell from solidifying and preventing clogging.

[0004] In the above technology, although the top block can move back and forth through the design of structures such as telescopic parts, thereby preventing the raw materials from condensing in the shell and thus avoiding material blockage, the above mixer cannot clean the inside of the tank immediately after mixing, which makes the raw materials remaining in the tank easy to stick and solidify, thus increasing the difficulty of subsequent cleaning.

[0005] Therefore, this utility model provides a mixer for refractory materials. Utility Model Content

[0024] 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.

[0025] Example: Figure 1-4 As shown, this utility model provides a refractory material mixer, including a mixing tank 1. A turntable 2 is rotatably connected to the top of the inner wall of the mixing tank 1. A groove 3 is provided at one end of the turntable 2. A first motor 4 is fixedly connected to one end of the groove 3. A first lead screw 5 is fixedly connected to the output end of the first motor 4. A slider 6 is threadedly connected to one end of the first lead screw 5. The slider 6 is slidably connected to the groove 3. A cylinder 7 is fixedly connected to the bottom of the slider 6. A stirring shaft 8 is fixedly connected to the output end of the cylinder 7. A scraper 9 is fixedly connected to one end of the stirring shaft 8. Sliding tubes 10 are slidably connected to both ends of the top of the mixing tank 1. The bottom of the two sliding tubes 10 are connected to an annular tube 11. Multiple nozzles 12 are provided at the bottom of the annular tube 11. A connecting arm 27 is fixedly connected to one end of the scraper 9. The connecting arm 27 is fixedly connected to the stirring shaft 8. Three stirring rods 28 are fixedly connected to the end of the stirring shaft 8 away from the connecting arm 27.

[0026] In this embodiment, when refractory materials need to be made into shaped products, such as refractory bricks, it is necessary to stir the raw materials and coagulant of the refractory materials. During stirring, the raw materials and coagulant are first put into the mixing tank 1 through the feed hopper 22. Then, the turntable 2 is driven to rotate, thereby driving the stirring shaft 8, stirring rod 28, connecting arm 27 and scraper 9 to rotate, thereby realizing the stirring of the raw materials. During the stirring process, some raw materials will adhere to the inner wall of the mixing tank 1 and the cover plate 24. If these raw materials are not scraped off in time, they will easily solidify, which will not only affect the stirring effect, but also increase the difficulty of subsequent cleaning. Therefore, the first motor 4 needs to be turned on during the stirring process. Under the drive of the first motor 4, the first lead screw 5 will rotate, thereby driving the slider 6, stirring shaft 8 and scraper 9 to move, so that the scraper 9 contacts the inner wall of the mixing tank 1. When cylinder 7 is opened, the stirring shaft 8 and scraper 9 are driven downwards, allowing scraper 9 to contact cover plate 24. During rotation, scraper 9 scrapes off the raw material adhering to mixing tank 1 and cover plate 24, thus making the mixing more thorough and reducing the difficulty of subsequent cleaning. After the raw material is fully mixed and emptied, some raw material remains inside mixing tank 1. To prevent this material from condensing, it is necessary to clean the inside of mixing tank 1 in a timely manner. At this time, cleaning fluid is supplied to two sliding pipes 10. This cleaning fluid flows into annular pipe 11 through sliding pipes 10 and is sprayed out from nozzles 12 on annular pipe 11, thereby cleaning the inside of mixing tank 1. The nozzles 12 on annular pipe 11 are either horizontally or inclined, so that the cleaning fluid can be sprayed at different angles, thus ensuring that the inside of mixing tank 1 is thoroughly rinsed.

[0027] The tops of the two sliding tubes 10 are connected to a connecting pipe 13. A water pump 14 is fixedly connected to one end of the side wall of the mixing tank 1. A hose 15 is connected to the output end of the water pump 14. The hose 15 is connected to the connecting pipe 13.

[0028] In this embodiment, when cleaning the inside of the mixing tank 1, the water pump 14 input terminal is connected to the cleaning liquid and the water pump 14 is turned on, so that the cleaning liquid flows smoothly into the annular pipe 11 through the hose 15, the connecting pipe 13 and the slide pipe 10.

[0029] A second lead screw 16 is rotatably connected to one end of the top of the mixing tank 1, and a connecting lug 17 is fixedly connected to one end of the connecting pipe 13. The second lead screw 16 is threadedly connected to the connecting lug 17. A support column 18 is fixedly connected to one end of the mixing tank 1 adjacent to the second lead screw 16. A second motor 19 is fixedly connected to the top of the support column 18. The output end of the second motor 19 is fixedly connected to the second lead screw 16.

[0030] In this embodiment, the second motor 19 is turned on during the cleaning process. Driven by the second motor 19, the second lead screw 16 rotates, thereby driving the connecting pipe 13 and the slide pipe 10 to move up and down, and in turn driving the annular pipe 11 to move up and down, so as to thoroughly rinse the inside of the mixing tank 1 and improve the cleaning effect. Before turning on the second motor 19, the first motor 4 is used to drive the stirring shaft 8 and the scraper 9 to move towards the center of the mixing tank 1, so that the annular pipe 11 can move up and down smoothly.

[0031] A third motor 20 is fixedly connected to the center of the top of the mixing tank 1. The output end of the third motor 20 is fixedly connected to the turntable 2. Four support legs 21 are fixedly connected to the bottom of the mixing tank 1.

[0032] In this embodiment, the third motor 20 is designed to drive the rotation of the turntable 2, and the support leg 21 supports the mixing tank 1.

[0033] A feed hopper 22 is provided at the top of the mixing tank 1, adjacent to the turntable 2. A discharge port 23 is provided at the center of the bottom of the mixing tank 1. A cover plate 24 is hinged to the discharge port 23 of the mixing tank 1. A hydraulic cylinder 25 is provided at one end of the cover plate 24. The output end of the hydraulic cylinder 25 is rotatably connected to the cover plate 24. A support shaft 26 is fixedly connected to the end of the hydraulic cylinder 25 away from the cover plate 24. The support shaft 26 is rotatably connected to the support leg 21.

[0034] In this embodiment, when it is necessary to discharge the mixed raw materials, the hydraulic cylinder 25 is opened, and the cover plate 24 is driven to rotate by the hydraulic cylinder 25, thereby opening the discharge port 23 so that the mixed raw materials can be discharged smoothly.

[0035] Working Principle: When refractory materials need to be made into shaped products, such as refractory bricks, the raw materials and coagulant of the refractory materials need to be mixed. During mixing, the raw materials and coagulant are first fed into the mixing tank 1 through the feed hopper 22. Then, the third motor 20 is turned on, and the turntable 2 rotates under the drive of the third motor 20, thereby driving the mixing shaft 8, mixing rod 28, connecting arm 27, and scraper 9 to rotate, thus mixing the raw materials. During the mixing process, some raw materials will adhere to the inner wall of the mixing tank 1 and the cover plate 24. If these raw materials are not scraped off in time, they will easily solidify, which will not only affect the mixing effect but also increase the difficulty of subsequent cleaning. Therefore, during the mixing process... During the process, the first motor 4 needs to be turned on. Driven by the first motor 4, the first lead screw 5 will rotate, thereby driving the slider 6, stirring shaft 8 and scraper 9 to move, so that the scraper 9 contacts the inner wall of the mixing tank 1. Then, the cylinder 7 is turned on, and the stirring shaft 8 and scraper 9 are driven to move downward through the cylinder 7, so that the scraper 9 contacts the cover plate 24. In this way, the scraper 9 can scrape off the raw materials attached to the mixing tank 1 and the cover plate 24 during the rotation, so that the mixing is more thorough and the subsequent cleaning difficulty is reduced. When the raw materials are thoroughly mixed, the hydraulic cylinder 25 is turned on, and the cover plate 24 is driven to rotate through the hydraulic cylinder 25, so that the discharge port 23 is opened, so that the mixed raw materials can be discharged smoothly.

[0036] After the raw materials are discharged, some raw materials remain inside the mixing tank 1. To prevent these materials from condensing, the inside of the mixing tank 1 needs to be cleaned promptly. During cleaning, the cover plate 24 is first rotated by the hydraulic cylinder 25 to cover the discharge port 23. Then, the water pump 14 is connected to the cleaning fluid and turned on. At this time, the cleaning fluid flows into the annular pipe 11 through the hose 15, connecting pipe 13, and sliding pipe 10, and is sprayed out from the nozzle 12 on the annular pipe 11, thereby cleaning the inside of the mixing tank 1. During the cleaning process, the third motor 20 is turned on, which drives the turntable 2 to rotate, thereby driving the mixing shaft 8 and scraper 9 to rotate. During rotation, the inner wall of the mixing tank 1 and the cover plate 24 are scraped, thereby improving the cleaning effect. After the scraper 9 scrapes the mixing tank 1 and the cover plate 24 for a period of time, the first motor 4 is turned on. The first motor 4 drives the first lead screw 5 to rotate, thereby driving the slider 6, the stirring shaft 8 and the scraper 9 to move towards the center of the mixing tank 1. At the same time, the cylinder 7 drives the stirring shaft 8 and the scraper 9 to move upward. At this time, the second motor 19 is turned on. Under the drive of the second motor 19, the second lead screw 16 will rotate, thereby driving the connecting pipe 13 and the sliding pipe 10 to move up and down, and then driving the annular pipe 11 to move up and down, so as to thoroughly rinse the inside of the mixing tank 1 and improve the cleaning effect.

[0037] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
