[0003] In actual use, existing automatic batching and mixing equipment for unshaped refractory materials requires manual pre-proportioning of powdered and liquid materials. However, manual proportioning is inaccurate and slow, resulting in inconsistent product quality. At the same time, the liquid material comes into direct contact with the powdered material through spraying, leading to poor mixing effect. Utility Model Content

A spring is provided on the inner wall of the fixing tube. One end of a connecting rod is fixedly installed on the side of the sealing block near the spring. A sealing plate is fixedly installed on the other end of the connecting rod.
[0006] As a preferred technical solution of this utility model: the threaded rod two passes through the rack, and the threaded rod two is threadedly connected to the rack.
[0007] As a preferred technical solution of this utility model: the rack is located outside the gear, and the gear meshes with the rack.
[0008] As a preferred embodiment of this utility model, the sealing ball is located on the inner wall of the suction tube, and the diameter of the sealing ball is the same as the diameter of the inner wall of the suction tube.
[0009] As a preferred technical solution of this utility model: the threaded rod one and the limiting rod respectively pass through the extension block one and the extension block two, and the threaded rod one and the extension block one are threadedly connected, and the limiting rod and the extension block two are slidably connected.
[0010] As a preferred technical solution of this utility model: the sealing plate and the fixed tube are the same size near the sealing plate, and the fixed tube is adapted to the shape of the sealing block near the sealing block. The diameter of the middle part of the inner wall of the fixed tube is larger than the diameter of the sealing block.
[0011] Compared with the prior art, the present invention has the following beneficial effects:
[0012] 1. This automatic batching and mixing equipment for unshaped refractory materials uses two weighing devices to weigh the powdery material inside the hopper and the liquid material inside the storage tank. Weighing device one sends the weight information of the hopper to the control center, which then calculates the required weight of the liquid material and sends the result to weighing device two. At this time, the control center controls motor two to start via weighing device one, which in turn drives extension block one and moving plate through threaded rod one, allowing the material inside the hopper to enter the mixing tank through the moving plate. Weighing device two then controls motor three to start, which opens the sealing ball through rack and pinion gears. At this time, the suction pump is started, which discharges the liquid from the storage tank into the mixing tank through the suction pipe. When the weight of the material inside the storage tank reaches the threshold, weighing device two controls motor three to reset the structure, thereby blocking the entry of liquid material and completing the automatic batching.
[0013] 2. This automatic batching and mixing equipment for unshaped refractory materials, by starting a suction pump, draws liquid in through a suction pipe, which then discharges the liquid through the suction pipe to the transmission rod. The liquid then reaches the inner wall of the stirring shaft through the transmission rod and enters the interior of the transmission pipe through the sealing head. At this time, the pressure inside the transmission pipe increases, which pushes the sealing block and causes it to move towards the inner wall of the fixed pipe. This allows the liquid inside the transmission pipe to be discharged to the outside of the fixed pipe through the gap between the sealing block and the inner wall of the fixed pipe. As the sealing block moves, it pushes the sealing plate outward, which in turn pushes the external material, causing the liquid material to be discharged from the middle of the powdered material.

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.
[0022] Please see Figure 1 - Figure 6 An automatic batching and mixing device for unshaped refractory materials includes a mixing tank 1. A motor 2, a control center 4, and a weighing device 5 are fixedly installed on the outer wall of the mixing tank 1. A weighing device 3 is fixedly installed on the top of the mixing tank 1. A hopper 6 is fixedly installed on the top of the weighing device 3. A motor 7 is fixedly installed on the outer wall of the hopper 6.

A moving plate 9 is slidably connected to the inner wall of the hopper 6. An extension block 10 and an extension block 11 are fixedly installed on the top of the moving plate 9. A limit rod 12 is fixedly installed on the inner wall of the hopper 6. A stirring shaft 13 is fixedly installed on the output shaft of the motor 2. A discharge port 14 is fixedly installed at the bottom of the mixing tank 1. A suction pump 16 is fixedly installed on the top of the liquid storage tank 15. A transmission rod 17 is fixedly installed on the outer wall of the suction pump 16. A sealing head 18 is fixedly installed on the wall. A motor 3 19 is fixedly installed on the top of the liquid storage tank 15. A rack 20 is slidably connected to the inner wall of the liquid storage tank 15. A rotating rod 24 is rotatably connected to the inner wall of the liquid storage tank 15. A gear 21 is fixedly installed at one end of the rotating rod 24. A sealing ball 23 is fixedly installed at the other end of the gear 21. A suction pipe 22 is fixedly installed on the inner wall of the liquid storage tank 15. A threaded rod 25 is fixedly installed on the output shaft of the motor 3 19. A support plate 26 and a connecting pipe 28 are fixedly installed on the outer wall of the stirring shaft 13. A transmission pipe 27 is fixedly installed on the outer wall of the support plate 26. A fixing pipe 29 is fixedly installed on the outer wall of the transmission pipe 27. A sealing block 30 is slidably connected to the inner wall of the fixing pipe 29. A spring 31 is provided on the inner wall of the fixing pipe 29. One end of a connecting rod 32 is fixedly installed on the side of the sealing block 30 near the spring 31. A sealing plate 33 is fixedly installed on the other end of the connecting rod 32.
[0023] In the above structure, the electrical connection between the second weighing device 5 and the third motor 19 enables the second weighing device 5 to control the start of the third motor 19. The electrical connection between the first weighing device 3 and the first motor 2 enables the first weighing device 3 to control the start of the first motor 2. Furthermore, the electrical connection between the control center 4 and the first motor 2 and the second weighing device 5 enables the control center 4 to control the start of the third motor 19 and the first motor 2 through the first weighing device 3 and the second weighing device 5.
[0024] In a preferred embodiment: the threaded rod 25 passes through the rack 20, and the threaded rod 25 is threadedly connected to the rack 20.
[0025] In the above structure, by starting the motor 3 19, the motor 3 19 drives the threaded rod 25 to rotate, and then drives the rack 20 to move through the threaded connection between the threaded rod 25 and the rack 20.
[0026] In a preferred embodiment, rack 20 is located outside gear 21, and gear 21 meshes with rack 20.
[0027] In the above structure, the rack 20 moves on the outer wall of the gear 21, thereby causing the rack 20 to drive the gear 21 to rotate, which in turn causes the gear 21 to drive the rotating rod 24 to rotate, which in turn causes the rotating rod 24 to drive the sealing ball 23 to rotate.
[0028] In a preferred embodiment, the sealing ball 23 is located on the inner wall of the suction tube 22, and the diameter of the sealing ball 23 is the same as the diameter of the inner wall of the suction tube 22.
[0029] In the above structure, the inner wall of the suction tube 22 is sealed by the sealing ball 23, thereby preventing the liquid from passing through the sealing ball 23. When the sealing ball 23 rotates, it drives the opening on the outer wall of the sealing ball 23 to rotate. When the opening on the outer wall of the sealing ball 23 rotates to be parallel to the inner wall of the suction tube 22, the liquid can pass through the opening on the outer wall of the sealing ball 23 to reach the top of the sealing ball 23.
[0030] In a preferred embodiment: the threaded rod 8 and the limiting rod 12 pass through the extension block 10 and the extension block 2 11 respectively, and the threaded rod 8 and the extension block 10 are threadedly connected, while the limiting rod 12 is slidably connected to the extension block 2 11.
[0031] In the above structure, by starting motor 7, motor 7 drives threaded rod 8 to rotate, which in turn drives extension block 10 to move through the threaded connection between threaded rod 8 and extension block 10. Extension block 10 then drives moving plate 9 to move, and moving plate 9 drives extension block 11 to move on the outer wall of limiting rod 12. Limiting rod 12 limits extension block 11, so that extension block 11 can only move on the outer wall of limiting rod 12 when moving. This limits moving plate 9 and prevents it from tilting when moving.
[0032] In a preferred embodiment: the sealing plate 33 and the fixing tube 29 are the same size near the sealing plate 33, and the fixing tube 29 is adapted to the shape of the sealing block 30 near the sealing block 30. The diameter of the middle part of the inner wall of the fixing tube 29 is larger than the diameter of the sealing block 30.
[0033] In the above structure, the increased pressure inside the transmission pipe 27 pushes the sealing block 30, causing it to move towards the inner wall of the fixed pipe 29. This allows the liquid inside the transmission pipe 27 to be discharged to the outside of the fixed pipe 29 through the gap between the sealing block 30 and the inner wall of the fixed pipe 29. As the sealing block 30 moves, it pushes the sealing plate 33 outward, thereby pushing the external material.
[0034] Working Principle: When using this equipment, the powdered material is placed inside the hopper 6, causing a change in the weight at the top of the weighing device 3. The weighing device 3 then sends this weight information to the control center 4, which calculates the weight ratio and sends the calculated ratio to the weighing device 5. At this time, the control center 4, through the weighing device 3, controls the motor 7 to start, which in turn drives the threaded rod 8 to rotate. The threaded rod 8, through its threaded connection with the extension block 10, moves the extension block 10, thereby... Extension block 10 drives the moving plate 9 to move, and the moving plate 9 drives extension block 2 11 to move on the outer wall of the limiting rod 12. At this time, the moving plate 9 no longer blocks the bottom of the hopper 6, allowing the material inside the hopper 6 to enter the mixing tank 1 through the moving plate 9. At this time, the control center 4 controls the motor 3 19 to start through the weighing device 2 5, which in turn drives the threaded rod 25 to rotate. The threaded connection between the threaded rod 25 and the rack 20 drives the rack 20 to move, which in turn drives the gear 21 to rotate, which in turn drives the rotating rod 24 to rotate. 24 drives the sealing ball 23 to rotate, making the opening of the sealing ball 23 parallel to the suction pipe 22. At this time, the suction pump 16 is started, which draws the liquid in through the suction pipe 22. The liquid then flows through the suction pipe 22 to the transmission rod 17, and then through the transmission rod 17 to the inner wall of the stirring shaft 13. It then enters the interior of the transmission pipe 27 through the sealing head 18. At this time, the pressure inside the transmission pipe 27 increases, which pushes the sealing block 30, causing the sealing block 30 to move towards the inner wall of the fixed pipe 29. This allows the liquid inside the transmission pipe 27 to pass through the sealing block 30 and the interior of the fixed pipe 29. The gap between the walls discharges to the outside of the fixed pipe 29. When the sealing block 30 moves, it pushes the sealing plate 33 outward, thereby pushing the external material and causing the liquid material to be discharged from the middle of the powder. At this time, the motor 2 is started, and the motor 2 drives the stirring shaft 13 to rotate. The stirring shaft 13 stirs the material. When the weighing device 5 senses that the material discharged from the inside of the liquid storage tank 15 has reached the threshold, the weighing device 5 sends a signal to the motor 19, causing the motor 19 to start and reset the structure, thereby sealing the sealing ball 23 and blocking the liquid flow, thus realizing automatic proportioning.
[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
