Description

Technical Field

[0001] This invention belongs to the field of sand mill technology, specifically a horizontal disc sand mill. Background Technology

[0002] A sand mill, also known as a bead mill, is a grinding equipment developed from a ball mill. It is primarily used for wet grinding of chemical liquid products and is widely applied in fields such as inks, coatings, and nanomaterials for pulverizing, grinding, and dispersing materials. The working principle of a sand mill involves a high-speed rotating dispersing disc agitating the grinding media and materials, causing strong shearing, scouring, and collision between the solid particles in the material and the grinding media, thereby achieving the purpose of pulverizing, grinding, and dispersing. Sand mills are characterized by wide material adaptability, high grinding efficiency, and good grinding quality. Their narrow grinding chamber and small lever gap, combined with a cooling system and automatic control system, enable continuous material processing and continuous discharge.

[0003] In existing technologies, sand mill grinding cylinders are generally equipped with water-cooling circulation systems. However, most grinding cylinders have a single-stage water-cooling chamber. This results in a significant decrease in heat dissipation efficiency of the cooling water in the subsequent flow path after entering the water-cooling chamber compared to the initial flow path. The temperature distribution within the entire grinding cylinder is uneven, exhibiting a multi-gradient pattern. Furthermore, existing water-cooling circulation systems cannot quickly cool the cooling water after it has absorbed heat. Combined with the single-stage water-cooling chamber flow structure, this leads to excessively high temperatures in the grinding cylinder after prolonged operation, resulting in reduced grinding efficiency, changes in material properties, and impact on the overall performance of the material and the grinding effect.

[0004] Therefore, the present invention provides a horizontal disc mill. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention proposes a horizontal disc-type sand mill. While existing sand mills typically feature a water-cooling circulation system on the grinding cylinder, most of these systems have a single-stage water-cooling chamber. This results in a significant decrease in heat dissipation efficiency of the cooling water along its subsequent flow path compared to the initial flow path, leading to uneven temperature distribution within the grinding cylinder and a multi-gradient pattern. Furthermore, existing water-cooling circulation systems cannot quickly cool the water after it has absorbed heat. Combined with the single-stage water-cooling chamber flow structure, this causes the grinding cylinder to overheat after prolonged operation, resulting in reduced grinding efficiency, changes in material properties, and negatively impacting the overall performance and grinding effect of the material.

Through the groove I provided on the spiral water flow plate I and the groove II provided on the spiral water flow plate II, not only is the heat dissipation area further increased, but the flow state of the cooling water is also changed, thereby improving the heat dissipation coefficient and heat transfer efficiency.

[0020] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0021] like Figures 1-10As shown in the embodiment of the present invention, a horizontal disc-type sand mill includes a body 1. A grinding cylinder 2, a cooling tower 3, and a water storage tank 5 are fixedly installed on the body 1. The cooling tower 3 is located on one side of the grinding cylinder 2, and the water storage tank 5 is located below the grinding cylinder 2. A water-cooling cavity 6 is provided on the cylinder wall of the grinding cylinder 2. An annular baffle 7 is fixedly connected to the inner wall of the water-cooling cavity 6. Spiral baffles 8 are symmetrically arranged on both sides of the annular baffle 7. Both spiral baffles 8 are fixedly connected to the inner wall of the water-cooling cavity 6. Water outlet pipes 9 are symmetrically arranged on both sides of the top of the annular baffle 7. One end of each water outlet pipe 9 is close to the top of the water-cooling cavity 6. The cooling tower 3 is connected to the top of the cooling tower 3 by a connecting pipe 10. The end of the connecting pipe 10 away from the cooling tower 3 is connected to two outlet pipes 9. The bottom of the annular baffle 7 is symmetrically equipped with two inlet pipes 14, one end of which is connected to the bottom of the water-cooling chamber 6. The inlet pipes 14 and the cooling tower 3 are connected by a water pump 11. During operation, when the grinding cylinder 2 is in grinding mode, the water pump 11, in conjunction with the outlet pipes 9, connecting pipes 10, and inlet pipes 14, allows the cooling water to circulate between the grinding chamber and the cooling tower 3. The cooling tower 3 can then be used to circulate the cooling water. The cooling water that has absorbed the heat from the grinding cylinder 2 is rapidly cooled. An annular baffle 7 effectively divides the water-cooled cavity 6 into two areas. Combined with two spiral baffles 8, the cooling water is diverted, flowing into the two separate sections of the water-cooled cavity 6. This achieves segmented heat dissipation for the grinding cylinder 2, preventing prolonged flow of cooling water within the water-cooled cavity 6 and mitigating the decreasing heat dissipation efficiency of the cooling water in subsequent flow paths. This effectively solves the problem that in existing technologies, while the grinding cylinder 2 of a sand mill is generally equipped with a water-cooling circulation system, the water-cooled cavity 6 within most grinding cylinders 2 lacks... The single-stage cooling system results in a significant decrease in heat dissipation efficiency of the cooling water in the subsequent flow path after entering the water-cooling chamber 6 compared to the initial flow path. This leads to uneven temperature distribution within the grinding cylinder 2, exhibiting a multi-gradient pattern. Furthermore, the existing water-cooling circulation system cannot quickly cool the cooling water after it has absorbed heat. Combined with the single-stage flow structure of the water-cooling chamber 6, the grinding cylinder 2 may experience excessively high temperatures after prolonged operation, resulting in reduced grinding efficiency, changes in material properties, and impacts on the overall performance of the material and the grinding effect.

[0022] Cooling tower 3 consists of an annular cone 21 and an annular cone 22. A spiral water flow plate 24 is fixedly connected to the inner wall of annular cone 21, and grooves 1 are evenly distributed on the spiral water flow plate 24. Annular cone 22 is located inside annular cone 21, and a spiral water flow plate 25 is fixedly connected to the inner wall of annular cone 22, and grooves 25 are evenly distributed on the spiral water flow plate 25. Connecting pipe 10 is connected to both annular cone 21 and annular cone 22. A water storage cylinder 30 is fixedly connected to the bottom. The water storage cylinder 30 is connected to the annular cone 21 through multiple connecting pipes 28. The water storage cylinder 30 is connected to the annular cone 22 through multiple connecting pipes 29. A water pump 11 is fixedly connected to the bottom of the water storage cylinder 30. One end of the water pump 11 is connected to the water storage cylinder 30, and the other end of the water pump 11 is fixedly connected to a connecting pipe 12. During operation, cooling water that has absorbed the heat of the grinding cylinder 2 enters the annular cone 21 from the water cooling chamber 6 through the outlet pipe 9 and the connecting pipe 10. After passing through the annular cone 22 and undergoing slow cooling, the water is discharged through connecting pipes 3 and 4. Then, it is pumped back into the water-cooling chamber 6 by water pump 11 in conjunction with connecting pipe 22 and inlet pipe 14, completing the circulation. The cooling tower 3, composed of annular cone 1 and annular cone 22, along with the spiral water flow plates 1 and 25 designed within it, increases the contact area between the cooling water and the inner wall of the cooling tower 3. This allows the heat absorbed by the cooling water to be transferred to the external environment more quickly through annular cone 1 and annular cone 22, thereby improving heat dissipation efficiency. The grooves 1 on spiral water flow plate 1 and 25 on spiral water flow plate 25 not only further increase the heat dissipation area but also change the flow state of the cooling water, improving the heat dissipation coefficient and heat transfer efficiency. At the same time, the increased interference and mixing of the cooling water helps to disrupt the conditions for scale formation, thus preventing scale from forming inside the cooling tower 3 and affecting heat transfer.

[0023] A heat sink 26 is fixed to the inner wall of the annular cone 21, and a heat sink 27 is fixed to the outer wall of the annular cone 22. Multiple fans 23 are installed on the upper part of the annular cone 21. During operation, the heat sinks 26 and 27 on the annular cone 21 and annular cone 22 respectively enable the cooling water to transfer the absorbed heat to the outside more quickly when it flows through. The fans 23 can quickly remove the heat accumulated on the heat sinks 26 and 27, so that the heat sinks 26 and 27 can dissipate heat more effectively.

[0024] A fixed frame 4 is fixed inside the water storage tank 5. The fixed frame 4 is hollow, and a cooling plate 13 is fixed to the inner wall of the fixed frame 4. The end of the connecting pipe 12 away from the water pump 11 is connected to the top of the inner cavity of the cooling plate 13. The bottom of the inner cavity of the cooling plate 13 is connected to the end of the water inlet pipe 14 away from the water cooling cavity 6. The bottom of the water storage tank 5 is V-shaped and tilted to one side. A water pump 16 is fixedly installed on one side of the water storage tank 5. The water pump 16 is connected to the bottom of the water storage tank 5 through a water pumping pipe 15. A main pipe 18 is fixed to the top side of the fixed frame 4. The main pipe 18 is connected to the water pump 16 through a water delivery pipe 17. Multiple branch pipes 19 are connected to the main pipe 18. The bottom of the branch pipes 19 is equipped with a spray nozzle. The head and multiple branch pipes 19 are evenly distributed above the cooling plate 13. During operation, when the water pump 11 pumps the cooling water after it has been cooled by the cooling tower 3 into the connecting pipe 2 12, the cooling water enters the cooling plate 13 from the connecting pipe 2 12. At this time, the water pump 2 16 pumps the water in the storage tank 5 into the main pipe 18 through the pumping pipe 15 and the delivery pipe 17. The water is then sprayed out by the multiple branch pipes 19 on the main pipe 18, forming a spray on the cooling plate 13, which further cools the cooling water flowing through the cooling plate 13. The sprayed water falls into the storage tank 5, and after being cooled by the slow flow in the storage tank 5, it is pumped out again by the water pump 2 16, forming a circulating spray on the cooling plate 13.

[0025] The cooling plate 13 is serpentine in shape, and through holes 20 are evenly distributed on the cooling plate 13. During operation, by designing the cooling plate 13 in a serpentine shape, not only can the cooling water flow slowly inside the cooling plate 13, but the contact area between the cooling water and the cooling plate 13 is also increased, which facilitates the cooling of the cooling plate 13 by the water sprayed from the branch pipe 19. By opening through holes 20 on the cooling plate 13, some of the water falling on the cooling plate 13 flows away from the gap between the cooling plate 13 and the inner wall of the fixing frame 4, while the other part can only flow down layer by layer through the through holes 20 on the cooling plate 13, which better absorbs the heat transferred from the cooling water to the surface of the cooling plate 13.

[0026] A fixed platform 33 is provided below the cooling tower 3, which is fixedly connected to the body 1. A gear 34 is rotatably connected to the fixed platform 33. A motor 31 is provided on one side of the fixed platform 33 and is fixedly installed on the body 1. A gear 32 is fixedly connected to the top of the output end of the motor 31. The gear 32 meshes with the gear 34. A reset component is provided between the bottom of the gear 34 and the fixed platform 33, and a cleaning component is provided on the top of the gear 34. During operation, after the heat sink 26 and the heat sink 27 have been used for a long time, the motor 31 drives the gear 32 to rotate, which causes the gear 34 to drive the cleaning component to rotate, thus cleaning the heat sink 26 and the heat sink 27. This prevents the dust attached to the heat sink 26 and the heat sink 27 from affecting the heat transfer efficiency. The reset component can be reset after rotating a certain angle, which can achieve the effect of reciprocating cleaning and avoid interference between the cleaning component and the connecting pipe 28 and the connecting pipe 29.

[0027] The reset assembly includes a spring 36 and a slider 37. The slider 37 is uniformly fixed to the bottom of the gear 34. The top of the fixed platform 33 is uniformly provided with arc-shaped grooves 35. The slider 37 is slidably connected to the arc-shaped grooves 35. The spring 36 is fixed between the slider 37 and the inner wall of the arc-shaped grooves 35. The gear 32 has teeth. During operation, because the gear 32 has teeth, after the gear 32 meshes with the gear 34 during rotation, the gear 34 drives the slider 37 to slide in the arc-shaped grooves 35 and compress the spring 36 until the gear 32 disengages from the gear 34. The slider 37 drives the gear 34 to reset under the elastic force of the spring 36. During this process, multiple cleaning components work together to complete the reciprocating cleaning of the heat sink 26 and the heat sink 27.

[0028] The cleaning assembly includes rotating rods 39 and brush plates 43. Multiple rotating rods 39 are evenly rotatably connected to the top of gear 2 34. The top of the rotating rods 39 extends between annular cone 1 21 and annular cone 2 22. A mounting block 42 is provided on the rotating rod 39, and an electromagnetic control unit is provided between the mounting block 42 and the brush plate 43. During operation, when dust cleaning is required, the electromagnetic control unit is turned on to control the brush plate 43 to slide towards heat sink 1 26 and heat sink 27, and to complete the reciprocating rotation cleaning in conjunction with the motor 31 and the reset assembly. After the dust cleaning is completed, the electromagnetic control unit is turned off, so that the brush plate 43 is away from heat sink 1 26 and heat sink 27 to avoid affecting the normal heat dissipation efficiency.

[0029] The electromagnetic control unit includes a fixed sleeve 44, an electromagnet 45, and a permanent magnet 46. Fixed sleeves 44 are fixed to both sides of the mounting block 42. An electromagnet 45 is fixed to the inner wall of the fixed sleeve 44. A permanent magnet 46 is slidably connected within the inner cavity of the fixed sleeve 44. A spring 47 is fixed between the electromagnet 45 and the permanent magnet 46. A connecting block 48 is fixed to the permanent magnet 46. The end of the connecting block 48 furthest from the permanent magnet 46 extends to the outside of the fixed sleeve 44 and is fixed to the brush plate 43. Connecting block 48 is slidably connected to the outer wall of fixed sleeve 44; during operation, when electromagnet 45 is energized, magnetic attraction is generated between electromagnet 45 and permanent magnet 46, causing permanent magnet 46 to slide towards electromagnet 45 while compressing spring 2 47, and driving brush plate 43 to move closer to heat sink 1 26 and heat sink 2 27. When electromagnet 45 is de-energized, permanent magnet 46 is reset under the elastic force of spring 2 47, and brush plate 43 moves away from heat sink 1 26 and heat sink 2 27.

[0030] Gear 38 is fixedly connected to the top of the outer side of the annular cone 22, and gear 40 is fixedly connected to the top of the rotating rod 39. Gear 38 and gear 40 are meshed together. A limiting rod 41 is provided on one side of the rotating rod 39. The bottom end of the limiting rod 41 is fixedly connected to the top of gear 24. The rotating rod 39 is provided with a reciprocating threaded groove. The mounting block 42 is threadedly connected to the reciprocating threaded groove, and the mounting block 42 is slidably connected to the limiting rod 41. During operation, when gear 24 rotates under the drive of motor 31, the rotating rod 39 drives gear 40 to move circumferentially. Wheel 40 meshes with gear 38 and drives the rotating rod 39 to rotate. This causes the mounting block 42, which slides with the limit rod 41, to slide up and down along the reciprocating threaded groove on the rotating rod 39. In conjunction with the electromagnetic control unit, the brush plate 43 can not only rotate back and forth to clean, but also slide up and down to clean, further improving the cleaning effect. In addition, when the brush plate 43 is away from the heat sink 26 and the heat sink 27, the up and down sliding can cause the bristles on the brush plate 43 to shake, shaking off the dust attached during the cleaning process.

[0031] Working principle: When the grinding cylinder 2 is in grinding mode, the water pump 11, in conjunction with the outlet pipe 9, connecting pipe 10, water storage tank 30, connecting pipe 2 12, cooling plate 13, and inlet pipe 14, allows cooling water to circulate between the grinding chamber and the cooling tower 3. The cooling tower 3 can quickly cool the cooling water that has absorbed heat from the grinding cylinder 2. By using an annular baffle 7, the water-cooled chamber 6 is effectively divided into two areas. Combined with two spiral baffles 8, the cooling water is diverted and enters the two parts of the water-cooled chamber 6 respectively, achieving segmented heat dissipation of the grinding cylinder 2. This avoids the cooling water flowing in the water-cooled chamber 6 for a long time and to a certain extent slows down the trend of decreasing heat dissipation efficiency of the cooling water in the subsequent flow path. When the grinding cylinder 2 absorbs heat... Cooling water from cylinder 2 enters the water-cooling chamber 6 through outlet pipe 9 and connecting pipe 10 into annular cone 21 and annular cone 22. After slow flow and cooling, it is discharged through connecting pipe 3 28 and connecting pipe 4 29, and then pumped back into the water-cooling chamber 6 by pump 11 in conjunction with connecting pipe 2 12, cooling plate 13, and inlet pipe 14, completing the circulation. The cooling tower 3, composed of annular cone 21 and annular cone 22, along with the spiral water flow plates 1 24 and 2 25 designed within it, increases the contact area between the cooling water and the inner wall of the cooling tower 3. This allows the heat absorbed by the cooling water to be transferred to the external environment more quickly through annular cone 21 and annular cone 22, thereby improving heat dissipation efficiency. The groove 1 on the cooling tower 4 and the groove 2 on the spiral water flow plate 25 not only further increase the heat dissipation area but also change the flow state of the cooling water, improving the heat dissipation coefficient and heat transfer efficiency. Simultaneously, the increased interference and mixing of the cooling water helps to disrupt the conditions for scale formation, thus preventing scale buildup inside the cooling tower 3 and its impact on heat transfer. By providing heat dissipation fins 26 and 27 on the annular cone 21 and annular cone 22 respectively, the cooling water can more quickly transfer the absorbed heat to the outside. The fan 23 can quickly remove the heat accumulated on the heat dissipation fins 26 and 27, allowing them to dissipate heat more effectively. When the water pump 1... After the cooling water dissipates heat from the cooling tower 3, it is pumped into the connecting pipe 12. The cooling water then enters the cooling plate 13 from the connecting pipe 12. At this time, the water pump 16, through the pumping pipe 15 and the supply pipe 17, pumps the water in the storage tank 5 into the main pipe 18. The water is then sprayed out from the multiple branch pipes 19 on the main pipe 18, forming a spray on the cooling plate 13, further cooling the cooling water flowing through the cooling plate 13. The sprayed water falls into the storage tank 5, where it dissipates heat through slow flow and is then pumped back into the water pump 16, forming a circulating spray on the cooling plate 13. By designing the cooling plate 13 in a serpentine shape, not only can the cooling water flow slowly within the cooling plate 13, but the contact area between the cooling water and the cooling plate 13 is also increased.To facilitate the cooling of the cooling plate 13 by the water sprayed from the branch pipe 19, through-holes 20 are provided in the cooling plate 13. This allows some of the water falling onto the cooling plate 13 to flow away through the gaps between the cooling plate 13 and the inner wall of the fixing frame 4, while the rest flows down layer by layer through the through-holes 20. This better absorbs the heat transferred from the cooling water to the surface of the cooling plate 13. After prolonged use, the heat sink 26 and heat sink 27 are cleaned by the cleaning assembly, driven by the motor 31 and the gear 32. This cleans the heat sink 26 and heat sink 27, preventing dust adhering to them from affecting heat transfer efficiency. The reset component allows the cleaning component to reset after rotating a certain angle, achieving both reciprocating cleaning and preventing interference between the cleaning component and connecting pipes 28 and 29. Because gear 32 has teeth, it meshes with gear 34 during rotation. Gear 34 then drives slider 37 to slide within the arc-shaped groove 35, compressing spring 36. Once gear 32 disengages from gear 34, slider 37, under the elastic force of spring 36, resets gear 34. During this process, multiple cleaning components work together to reciprocate the cleaning of heat sinks 26 and 27. When dust removal is required, the opening... The electromagnetic control unit controls the brush plate 43 to slide towards heat sink 26 and heat sink 27, working in conjunction with the motor 31 and the reset assembly to complete the reciprocating rotation cleaning. After cleaning, the electromagnetic control unit is turned off, causing the brush plate 43 to move away from heat sink 26 and heat sink 27 to avoid affecting normal heat dissipation efficiency. When the electromagnet 45 is energized, a magnetic attraction is generated between the electromagnet 45 and the permanent magnet 46, causing the permanent magnet 46 to slide towards the electromagnet 45 while compressing the spring 47, thus moving the brush plate 43 closer to heat sink 26 and heat sink 27. When the electromagnet 45 is de-energized, the permanent magnet 46 resets under the elastic force of the spring 47, and the brush plate 43 moves away from heat sink 26 and heat sink 27. When heat sink 27 is rotated by gear 24 driven by motor 31, rotating rod 39 drives gear 40 to move circumferentially. Gear 40 meshes with gear 38 and drives rotating rod 39 to rotate. This causes mounting block 42, which slides against limiting rod 41, to slide up and down along the reciprocating threaded groove on rotating rod 39. This, in conjunction with the electromagnetic control unit, allows brush plate 43 to not only rotate back and forth for cleaning but also slide up and down for cleaning, further improving the cleaning effect. Additionally, when brush plate 43 is away from heat sinks 26 and 27, its up-and-down sliding motion causes the bristles on brush plate 43 to vibrate, shaking off dust adhering during cleaning.
