Description

Technical Field

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

[0002] Refractory materials refer to a class of inorganic non-metallic materials with a refractoriness of not less than 1580℃. Refractoriness refers to the Celsius temperature at which a conical specimen of refractory material resists high temperature without softening or melting under no load. However, the definition based solely on refractoriness is no longer sufficient to fully describe refractory materials. 1580℃ is not absolute. It is now defined as any material whose physical and chemical properties allow it to be used in a high-temperature environment. Commonly used refractory materials include AZS bricks and corundum bricks. When producing refractory materials, a granulator for refractory material production is required.

[0003] Traditional granulators mostly lack effective screening structures. After granulation of refractory materials, screening is necessary to improve the overall quality of the refractory particles. However, traditional granulators lack effective screening structures, requiring manual screening by operators. While this method can effectively screen the particles, it is time-consuming and labor-intensive, reducing screening efficiency and increasing the workload of operators. Furthermore, the screening process generates a large amount of dust and other impurities. If the gas containing dust and impurities is not purified, it will pollute the environment and negatively impact the health of operators who inhale large amounts of dust, thus reducing the overall practicality and environmental friendliness of the equipment.

[0004] Based on this, a granulator for refractory material production is now provided, which can eliminate the drawbacks of existing equipment. Utility Model Content

[0033] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0034] In one embodiment, such as Figures 1-5As shown, a granulator for refractory material production includes a base 1, a support frame 2 fixedly installed on the rear of the upper surface of the base 1, a granulation cylinder 3 provided in front of the support frame 2, a discharge pipe 33 connected to the bottom of the granulation cylinder 3 through a solenoid valve 32, a fixing ring 4 fixedly connected to the outside of the granulation cylinder 3, an L-shaped plate 5 fixedly connected to the left and right outer walls of the fixing ring 4, the rear surfaces of the two L-shaped plates 5 fixedly connected to the front surface of the support frame 2, and a closed cover 6 provided directly above the granulation cylinder 3.

[0035] A screening frame 11 is provided directly below the discharge pipe 33. Guide plates 12 are symmetrically provided on the front and rear surfaces of the screening frame 11. Multiple support plates 13 are fixedly connected to the upper surface of the base 1. A guide rod 14 is fixedly connected between every two support plates 13. Guide grooves for the guide rod 14 to move are opened inside the multiple guide plates 12. A collection frame 15 is provided directly below the screening frame 11.

[0036] An adjustment component is located in the middle of the upper surface of the support frame 2 and is used to adjust the height position of the closed cover 6.

[0037] A stirring and granulation assembly is disposed on the upper surface of the closed cover 6 and is used for granulation processing;

[0038] A screening component is set on the upper surface of the base 1 and is used to screen the granulated particulate material.

[0039] The purification component is located above the base 1 and is used to adsorb and purify the powder generated during the sieving process of particulate materials.

[0040] In this embodiment, when refractory materials need to be granulated, the raw materials are first added to the granulation cylinder 3. The adjusting component then starts operating, effectively adjusting the height of the closed cover 6. The closed cover 6 then moves the stirring granulation component synchronously. When the closed cover 6 is closed outside the granulation cylinder 3, the stirring granulation component starts operating, effectively mixing and granulating the raw materials. After granulation, the solenoid valve 32 opens, and the particles fall through the discharge pipe 33 into the screening frame 11. When the particles fall into the screening frame 11, the screening component starts operating. The screening component can effectively drive the screening frame 11 to move back and forth, thereby effectively screening the particles through the screening frame 11, which can effectively improve the overall quality of the particles and avoid the situation of particles being seriously inconsistent in size. The screened particles will naturally fall into the collection frame 15, at which point the refractory material can be granulated. During the particle screening process, a large amount of dust and other impurities will be generated. At this time, the purification component starts to operate. The purification component can effectively adsorb and purify the gas containing dust and other impurities, thereby effectively protecting the environment and the health of the staff, and effectively improving the overall environmental protection of the device.

[0041] In one embodiment, such as Figure 2 As shown, the adjustment assembly includes an adjustment plate 16 fixedly connected to the upper surface of the support frame 2. A first motor 17 is fixedly connected to the upper surface of the adjustment plate 16. The output shaft of the first motor 17 is fixedly connected to a threaded rod 18 via a coupling. The other end of the threaded rod 18 is rotatably connected to the inner bottom end of the adjustment plate 16. A threaded plate 19 is threadedly connected to the outer side of the threaded rod 18. A guide groove for the threaded plate 19 to move is provided on the front surface of the adjustment plate 16. The front surface of the threaded plate 19 is fixedly connected to the rear surface of the closed cover 6. When it is necessary to adjust the height position of the closed cover 6, the first motor 17 starts to run. At this time, the first motor 17 will drive the threaded rod 18 to rotate synchronously, and the threaded plate 19 will move synchronously outside the threaded rod 18, driving the closed cover 6 to move synchronously. The closed cover 6 then drives the stirring and granulation assembly to move synchronously. At this time, the height position of the closed cover 6 and the stirring and granulation assembly can be adjusted.

[0042] In one embodiment, such as Figures 1-3As shown, positioning rods 9 are symmetrically arranged on the upper surface of the base 1. The top of each positioning rod 9 is fixedly connected to a limiting plate 10. Each positioning rod 9 is slidably connected to a moving block 8. The opposite side of each moving block 8 is fixedly connected to the outside of the closing cover 6 through a connecting rod 7. During the movement of the closing cover 6, the connecting rod 7 will also move synchronously. The connecting rod 7 will then drive the moving block 8 to move synchronously outside the positioning rod 9. At this time, the stability of the closing cover 6 during the movement can be effectively improved by the cooperation between the moving block 8 and the positioning rod 9.

[0043] In one embodiment, such as Figures 1-3 As shown, the stirring and granulation assembly includes a second motor 20 fixedly connected to the upper surface of the closed cover 6. The output shaft of the second motor 20 is fixedly connected to a rotating rod 21 via a coupling. Multiple stirring and mixing rods 22 are fixedly connected to the outer wall of the rotating rod 21. When the raw material needs to be granulated, the second motor 20 starts to run. At this time, the second motor 20 will drive the rotating rod 21 to rotate synchronously, and the rotating rod 21 will then drive the stirring and mixing rods 22 to rotate synchronously. At this time, the raw material inside the granulation cylinder 3 can be mixed and granulated by the stirring and mixing rods 22.

[0044] In one embodiment, such as Figure 2 , Figure 4 and Figure 5As shown, the screening assembly includes a left mounting bracket 34 and a right mounting bracket 39, which are respectively fixedly connected to the upper surface of the base 1. A third motor 35 is fixedly connected to the upper surface of the left mounting bracket 34. The output shaft of the third motor 35 is fixedly connected to a drive rod 36 via a coupling. The other end of the drive rod 36 is rotatably connected to the upper surface of the base 1. A cam 37 is fixedly connected to the outside of the drive rod 36. An abutment plate 38 is fixedly connected to the left side surface of the screening frame 11. A movable groove for the cam 37 to move is opened on the left side surface of the abutment plate 38. Telescopic rods 40 are symmetrically arranged on the left side surface of the right mounting bracket 39. The telescopic ends of the two telescopic rods 40 are fixedly connected to the right side surface of the screening frame 11. A return spring 41 is sleeved on the outside of the two telescopic rods 40. The two ends of the two return springs 41 are respectively connected to the right mounting bracket. The third motor 35 is fixedly connected to the opposite side of the sieve frame 11. When the particles need to be sieved, the third motor 35 starts to run. At this time, the third motor 35 drives the drive rod 36 to rotate synchronously. The drive rod 36 then drives the cam 37 to rotate synchronously. During the rotation of the cam 37, it will continuously abut against the contact plate 38. The contact plate 38 then drives the sieve frame 11 to move synchronously. During the movement of the sieve frame 11 to the right, it will squeeze the telescopic rod 40 and the return spring 41. When the cam 37 continues to rotate, the return spring 41 will reset, driving the sieve frame 11 to move synchronously to the left. This cycle repeats, which can effectively drive the sieve frame 11 to move back and forth, so that the particles can be effectively sieved through the sieve frame 11.

[0045] In one embodiment, such as Figures 1-3 As shown, both telescopic rods 40 are fitted with bellows covers 42. The two ends of the bellows covers 42 are fixedly connected to the opposite side of the right mounting bracket 39 and the screening frame 11, respectively. By setting the bellows covers 42, the telescopic rods 40 and the return spring 41 can be effectively protected from dust, thereby effectively extending the service life of the telescopic rods 40 and the return spring 41, without affecting the normal use of the telescopic rods 40 and the return spring 41.

[0046] In one embodiment, such as Figures 1-3As shown, the purification assembly includes a vacuum pump 24 and a purification chamber 23, which are fixedly connected to the upper surface of the right mounting bracket 39. The air inlet of the vacuum pump 24 is connected to a branch metal bellows 25, and both air inlets of the branch metal bellows 25 are connected to a vacuum hood 26. The air outlet of the vacuum pump 24 is connected to the left side surface of the purification chamber 23 through a pipe. The interior of the purification chamber 23 is equipped with an activated carbon filter plate 27, and a top plate 28 is fixedly connected to the upper surface of the activated carbon filter plate 27. A handle is fixedly connected to the upper surface of the top plate 28. Two exhaust pipes are connected to the right side surface of the purification chamber 23. 31. During the particle screening process, a large amount of dust and other impurities will be generated. At this time, the dust pump 24 starts to run. The dust pump 24 will draw the gas containing dust and other impurities into the purification chamber 23 through the dust hood 26. When the gas containing dust and other impurities enters the purification chamber 23, the activated carbon filter plate 27 can effectively filter and purify the gas containing dust and other impurities. The purified gas will be discharged through the exhaust pipe 31. At this time, the environment and the health of the staff can be protected to a certain extent, and the overall environmental protection of the device can be effectively improved.

[0047] In one embodiment, such as Figure 3 As shown, the bottom of the top plate 28 is symmetrically provided with insert blocks 29. The front and rear surfaces of the purification box 23 are fixedly connected with fixing frames 30. The upper surfaces of the two fixing frames 30 are provided with slots for the insert blocks 29 to move. The two insert blocks 29 are fixedly connected to the fixing frames 30 by bolts. When it is necessary to disassemble and replace the activated carbon filter plate 27, simply unscrew the bolts and pull the handle. At this time, the handle will drive the top plate 28 and the activated carbon filter plate 27 to move synchronously. The top plate 28 will then drive the insert blocks 29 to move synchronously. When the insert blocks 29 are disengaged from the inside of the fixing frames 30, the activated carbon filter plate 27 can be disassembled, which makes it convenient for the staff to replace the activated carbon filter plate 27.

[0048] The above embodiment discloses a granulator for refractory material production. When refractory materials need to be granulated, the raw material is first added to the granulation cylinder 3. At this time, the first motor 17 starts running, effectively adjusting the height of the closed cover 6. The closed cover 6 then drives the second motor 20 and the mixing rod 22 to move synchronously. When the closed cover 6 is closed outside the granulation cylinder 3, the second motor 20 starts running, driving the mixing rod 22 to rotate synchronously. This allows for effective mixing and granulation of the raw material through the mixing rod 22. After granulation, the solenoid valve 32 opens, and the particles fall through the discharge pipe 33 into the screening frame 11. When the refractory material is inside the sieve 11, the third motor 35 starts running. At this time, the third motor 35 drives the sieve 11 to move back and forth, so that the particles can be effectively sieved through the sieve 11, thereby effectively improving the overall quality of the particles and avoiding the situation where the particles are seriously inconsistent in size. The sieved particles will fall naturally into the collection frame 15, and the refractory material can then be granulated. During the particle sieving process, a large amount of dust and other impurities will be generated. At this time, the dust pump 24 starts running. The dust pump 24 can effectively draw the gas containing dust and other impurities into the purification box 23 for adsorption and purification treatment, thereby effectively protecting the environment and the health of the staff, and effectively improving the overall environmental protection and practicality of the device.

[0049] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
