Description
Technical Field
[0001] This utility model relates to the field of refractory material preparation technology, and in particular to a mixing machine for producing refractory castables. Background Technology
[0002] A mixing machine for refractory castable production is mainly used for the efficient mixing and refining of refractory castables. Through a powerful stirring and mixing structure, a precise material ratio control device, and a wear-resistant and high-temperature resistant machine body material, combined with an adjustable mixing speed and a uniform material dispersion device, it can achieve full integration, uniform mixing and performance optimization of materials in scenarios such as refractory material production, preparation of industrial kiln lining materials, and processing of raw materials for refractory layers of high-temperature equipment. It is suitable for mixing and processing refractory castable raw materials with different particle sizes and compositions.
[0003] A mixing mill for producing refractory castables mainly consists of a mixing and blending device, a material conveying device, a temperature control component, and a wear-resistant casing. Its working principle is as follows: materials enter the mixing chamber through the conveying device; the spiral blades of the mixing and blending device rotate at high speed, shearing, compressing, and tumbling the refractory aggregates, binders, and additives; simultaneously, the temperature control component adjusts the temperature inside the chamber according to the material characteristics to prevent abnormal temperatures from affecting material performance; and the wear-resistant casing reduces wear on the equipment during the mixing process, ensuring that all raw materials are fully integrated to form a uniform refractory castable that meets the performance requirements for subsequent molding and use.
[0004] In the use of traditional refractory castable production mixing machines, materials tend to adhere to the inner wall of the mixing drum and are difficult to remove, resulting in a large accumulation and clumping of materials, which seriously affects the mixing effect. These adhered materials not only occupy the mixing space, reducing the effective mixing area, but also gradually solidify and harden due to long-term retention, resulting in uneven texture of the final refractory castable. Therefore, a new refractory castable production mixing machine is proposed to solve the above problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a mixing machine for the production of refractory castables, which aims to improve the problem in the prior art where materials easily adhere to the inner wall of the mixing tank and are difficult to remove, resulting in a large amount of material accumulating and agglomerating.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A mixing machine for producing refractory castables includes a support frame. A motor is fixedly connected to the top of the support frame. A rotating rod is fixedly connected to the drive end of the motor. A mixing drum is rotatably connected to the outside of the rotating rod. A collision rod is fixedly connected to the front end of the rotating rod. A limit block is fixedly connected to the front end of the mixing drum. A fixing block is fixedly connected inside the limit block. A telescopic rod is fixedly connected to the rear end of the fixing block. A connecting block is fixedly connected to the rear end of the telescopic rod. A contact block is fixedly connected to the rear end of the connecting block. A spring is sleeved on the outside of the telescopic rod. A support block is fixedly connected to the top of the mixing drum. An adjustment component is provided at the top of the support block.
[0008] As a further description of the above technical solution:
[0009] The adjustment assembly includes a second motor, the bottom end of which is fixedly connected to the top of the support block. A second rotating rod is fixedly connected to the drive end of the second motor. A rotating blade is fixedly connected to the outside of the second rotating rod. A first rotating block is fixedly connected to the right end of the second rotating rod. A fixed shaft is rotatably connected to the right end of the first rotating block. A driven rod is fixedly connected to the outside of the fixed shaft. A fixed column is fixedly connected to the top of the driven rod. A second rotating block is rotatably connected to the left end of the fixed column. A third rotating rod is fixedly connected to the left end of the second rotating block. A stirring blade is fixedly connected to the outside of the third rotating rod. A feed inlet is fixedly connected to the top of the mixing tank.
[0010] As a further description of the above technical solution:
[0011] A connecting column is fixedly connected to the rear end of the rotating rod, and a stirring column is fixedly connected to the outside of the connecting column;
[0012] As a further description of the above technical solution:
[0013] A spiral is fixedly connected to the outside of the rotating rod, and the outside of the stirring column is in contact with the inside of the stirring tank;
[0014] As a further description of the above technical solution:
[0015] The rear end of the mixing tank is fixedly connected to a discharge port, and the outside of the collision rod is slidably connected to the front end of the mixing tank.
[0016] As a further description of the above technical solution:
[0017] One end of the spring is fixedly connected to the rear end of the fixing block, and the other end of the spring is fixedly connected to the front end of the connecting block;
[0018] As a further description of the above technical solution:
[0019] The outside of the rotating blade is slidably connected to the inside of the feed inlet, and the rotating rod is rotatably connected to the inside of the feed inlet;
[0020] As a further description of the above technical solution:
[0021] The contact block is oblique in shape, and its rear end contacts the front end of the mixing tank.
[0022] This utility model has the following beneficial effects:
[0023] 1. In this utility model, after the material flows into the mixing tank, the motor drives the rotating rod to rotate, causing the connecting column to drive the mixing column to rotate. When the mixing column rotates, it can repeatedly scrape the inner wall of the mixing tank, preventing the material from adhering to the inner wall during mixing and affecting the mixing effect. At the same time, the rotating rod drives the collision rod to rotate. When the collision rod rotates to the designated position and collides with the contact block, the contact block slides into the limiting block, and the spring is compressed. After the collision, the compressed spring pushes the contact block in the opposite direction, causing it to hit the front end of the mixing tank, causing the mixing tank to vibrate, and facilitating the next impact. This collision allows the material adhering to the inner wall to slide back into the mixing area, preventing long-term accumulation into lumps. For materials that have already solidified, continuous vibration can break up the lumps, keeping the material loose. Combined with the rotation of the mixing blades, it leaves sufficient gaps between the materials, reducing mutual adhesion.
[0024] 2. In this utility model, the material is fed into the feed inlet, and the second motor is started. The second motor drives the second rotating rod to rotate the rotating blade. By adjusting its speed, the feed rate can be changed to meet different conveying needs. At the same time, the second rotating rod drives the first rotating block to rotate, which in turn drives the second rotating block to rotate, thereby causing the third rotating rod to rotate the stirring blade. The stirring blade can pre-cut the material, which can prevent it from accumulating in the mixing tank, ensure continuous material flow, provide raw materials with more uniform particle size for subsequent processes, and reduce damage to the equipment due to excessive differences in material particles.

[0032] 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.
[0033] Reference Figures 1 to 3 This utility model provides an embodiment of a mixing machine for producing refractory castables, including a support frame 1. The support frame 1 provides a stable support foundation for a motor 2. The top of the support frame 1 is fixedly connected to the motor 2, which is a power source providing driving force for the rotation of a rotating rod 3. The driving end of the motor 2 is fixedly connected to the rotating rod 3, which transmits the power of the motor 2 to a stirring column 24. A stirring tank 4 is rotatably connected to the outside of the rotating rod 3. The rotatable connection between the rotating rod 3 and the stirring tank 4 allows the rotating rod 3 to rotate independently inside the stirring tank 4. The front end of the moving rod 3 is fixedly connected to the collision rod 5. The collision rod 5 can rotate synchronously with the rotation of the moving rod 3, providing a motion basis for the collision with the contact block 10. The front end of the mixing tank 4 is fixedly connected to the limit block 6, which can support the fixed block 7. The inside of the limit block 6 is fixedly connected to the fixed block 7, which provides an installation basis for the telescopic rod 8 and the spring 11, ensuring that these components can operate stably. The rear end of the fixed block 7 is fixedly connected to the telescopic rod 8, which can extend and retract when the collision rod 5 collides with the contact block 10, and work with the spring 11 to achieve buffering and reset.
[0034] A connecting block 9 is fixedly connected to the rear end of the telescopic rod 8. The connecting block 9 connects the telescopic rod 8 and the contact block 10. The contact block 10 can directly contact the collision rod 5, so that the contact block 10 collides with the mixing tank 4. A spring 11 is sleeved on the outside of the telescopic rod 8. The spring 11 can store elastic potential energy and push the contact block 10 to reset after being collided, preparing for the next collision. A support block 12 is fixedly connected to the top of the mixing tank 4. The support block 12 provides the installation base for the motor 13. An adjustment component is provided at the top of the support block 12. The adjustment component can adjust the different material input amounts according to actual production needs. A discharge port 26 is fixedly connected to the rear end of the mixing tank 4. The material after mixing can be smoothly discharged through the discharge port 26 to complete the mixing. The collision rod 5 is slidably connected to the front end of the mixing tank 4. Through the sliding connection between the collision rod 5 and the mixing tank 4, it is ensured that the collision rod 5 can smoothly interact with the contact block 10 during rotation, without affecting the stability of the mixing tank 4.
[0035] One end of the spring 11 is fixedly connected to the rear end of the fixed block 7, and the other end of the spring 11 is fixedly connected to the front end of the connecting block 9. Through this connection, the spring 11 can directly transmit the elastic force to the connecting block 9, causing the contact block 10 to reset. The contact block 10 is oblique in shape. The oblique design allows the collision rod 5 to more effectively transmit the force to the contact block 10 when it collides with the contact block 10, causing the contact block 10 to move. The rear end of the contact block 10 contacts the front end of the mixing tank 4. The contact between the contact block 10 and the mixing tank 4 ensures that the contact block 10 can accurately collide with the front end of the mixing tank 4 when it resets, causing the mixing tank 4 to vibrate.
[0036] Reference Figure 1 , Figure 4 and Figure 5The adjustment assembly includes a second motor 13, which provides power for the rotation of the second rotating rod 14. The bottom end of the second motor 13 is fixedly connected to the top end of the support block 12, which provides a stable mounting base for the second motor 13, ensuring that it will not move during operation. The drive end of the second motor 13 is fixedly connected to the second rotating rod 14, and the power output from the second motor 13 can be transmitted to the second rotating rod 14, causing it to rotate. A rotating blade 15 is fixedly connected to the outside of the second rotating rod 14, and the rotation of the second rotating rod 14 causes the rotating blade 15 to rotate accordingly, thereby adjusting the feed rate. The function of the rotating rod 14 is as follows: the right end of the rotating rod 14 is fixedly connected to the rotating block 16. The rotation of the rotating rod 14 will synchronously drive the rotating block 16 to move, providing power for the movement of the driven rod 18. The right end of the rotating block 16 is rotatably connected to the fixed shaft 17. The driven rod 18 can rotate with the rotating block 16 through the fixed shaft 17. The driven rod 18 is fixedly connected to the outside of the fixed shaft 17. The rotation of the fixed shaft 17 will drive the driven rod 18 to move around the fixed shaft 17 as the fulcrum. The top end of the driven rod 18 is fixedly connected to the fixed column 19. The movement of the driven rod 18 can drive the rotating block 20 to move.
[0037] A rotating block 20 is rotatably connected to the left end of the fixed column 19. The movement of the fixed column 19 drives the rotating block 20 to rotate. A rotating rod 3 21 is fixedly connected to the left end of the rotating block 20. The rotation of the rotating block 20 drives the rotating rod 3 21 to rotate synchronously, providing power to the stirring blade 22. The stirring blade 22 is fixedly connected to the outside of the rotating rod 3 21. The rotation of the stirring blade 22 can realize the pre-cutting function of the material. A feed inlet 27 is fixedly connected to the top of the mixing tank 4. The feed inlet 27 can guide the material to accurately enter the interior of the mixing tank 4. A connecting column 23 is fixedly connected to the rear end of the rotating rod 3. The rotation of the rotating rod 3 drives the connecting column 23 to rotate. A stirring column 24 is fixedly connected to the outside of the connecting column 23. The rotation of the stirring column 24 can stir the material inside the mixing tank 4. The materials are thoroughly mixed. A spiral 25 is fixedly connected to the outside of the rotating rod 3. When the rotating rod 3 rotates, it drives the spiral 25 to rotate, which can push the materials to flow in a certain direction in the mixing tank 4. The outside of the stirring column 24 is in contact with the inside of the mixing tank 4. Through contact, the stirring column 24 can scrape off the material attached to the inner wall of the mixing tank 4 during rotation, avoiding material residue. The outside of the rotating blade 15 is slidably connected to the inside of the feed inlet 27. When the rotating blade 15 slides and rotates in the feed inlet 27, the material input can be adjusted by the rotating blade 15 to adapt to different material input requirements. The rotating rod 3 21 is rotatably connected to the inside of the feed inlet 27. Through the rotatable connection, it is ensured that the rotating rod 3 21 can drive the stirring blade 22 to operate in the feed inlet 27, realizing material pre-cutting.
[0038] Working principle: When the operator uses the refractory castable production mixing machine, the material is conveyed into the feed inlet 27, and the motor 13 is started. The motor 13 drives the rotating rod 14 to rotate the rotating blade 15. By adjusting the rotation of the rotating blade 15, the amount of material fed can be changed to meet different material conveying needs. At the same time, the rotation of the rotating rod 14 drives the rotating block 16 to rotate. The rotation of the rotating block 16 causes the driven rod 18 to drive the rotating block 20 to rotate. The rotation of the rotating block 20 causes the rotating rod 21 to drive the stirring blade 22 to rotate. Through the rotation of the stirring blade 22, the material is pre-cut to avoid accumulation inside the mixing tank 4, ensuring that the material maintains a continuous flow state, providing raw materials with more uniform particle size for subsequent processes, and reducing the damage to the equipment caused by excessive differences in material particles.
[0039] When the material flows into the mixing tank 4, motor 2 is started. Motor 2 drives rotating rod 3 to rotate, which in turn drives stirring rod 24 to rotate. The rotation of stirring rod 24 repeatedly scrapes the material adhering to the inner wall of mixing tank 4, preventing the material from adhering to the inner wall of mixing tank 4 during mixing and affecting the final mixing effect. At the same time, the rotation of rotating rod 3 drives collision rod 5 to rotate. When collision rod 5 rotates to the designated position, it collides with contact block 10, causing contact block 10 to slide into the interior of limiting block 6. At this time, spring 11 is compressed. When collision rod 5 and contact block 10 collide... After the collision, the compressed spring 11 pushes the contact block 10 in the opposite direction, causing the contact block 10 to collide with the front end of the mixing tank 4, thereby causing the mixing tank 4 to vibrate. At the same time, in preparation for the next impact, the collision between the contact block 10 and the mixing tank 4 allows the material attached to the inner wall of the mixing tank 4 to slide back into the mixing zone, avoiding long-term accumulation into lumps. At the same time, for materials that have already solidified, the continuous collision vibration can break the initial clumps, keeping the materials in a loose state. Combined with the rotation of the stirring blade 22, it maintains sufficient gaps between the materials, reducing the chance of them sticking together.
[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
