Technical Field

[0002] Sand mill, also known as bead mill, is a grinding equipment developed from ball mill; it is mainly used for wet grinding of chemical liquid products, and is widely used in ink, coating, nanomaterials and other fields to crush, grind and disperse materials. The working principle of sand mill is to stir the grinding medium and material through the high-speed rotating dispersion disk, so that the solid particles in the material and the grinding medium produce strong shear, scouring and collision, so as to achieve the purpose of crushing, grinding and dispersion. Sand mill has the characteristics of wide material adaptability, high grinding efficiency and good grinding quality; its grinding chamber is narrow, the clearance of the lever is small, and it can realize continuous processing and continuous discharging of materials with the cooling system and automatic control system.

[0003] In the prior art, the grinding cylinder of the sand mill is generally equipped with a water cooling circulation system, but the water cooling chambers in most grinding cylinders are of a one-stage type. This results in that after the cooling water enters the water cooling chamber, the heat dissipation efficiency on the subsequent flow path is significantly reduced compared to the heat dissipation efficiency on the initial flow path, and the temperature distribution in the entire grinding cylinder is uneven, presenting a multi-gradient type. In addition, the existing water cooling circulation system cannot quickly cool down the cooling water after absorbing heat. Combined with the one-stage water cooling chamber flow structure, the grinding cylinder will have an overly high temperature after working for a long time, which will cause the grinding efficiency to decrease, the properties of the material to change, and the overall performance and grinding effect of the material to be affected.

[0004] To this end, the present invention provides a horizontal disc type sand mill. Summary of the invention

DETAILED DESCRIPTION

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0021] like Figure 1-Figure 10As shown, a horizontal disc sand mill according to an embodiment of the present invention comprises a machine body 1, on which a grinding cylinder 2, a cooling tower 3 and a water storage tank 5 are fixedly mounted, the cooling tower 3 is located on one side of the grinding cylinder 2, the water storage tank 5 is located below the grinding cylinder 2, a water cooling chamber 6 is provided on the cylinder wall of the grinding cylinder 2, an annular partition plate 7 is fixedly connected to the inner wall of the water cooling chamber 6, spiral partition plates 8 are symmetrically provided on both sides of the annular partition plate 7, and the two spiral partition plates 8 are fixedly connected to the inner wall of the water cooling chamber 6, and water outlet pipes 9 are symmetrically provided on both sides of the top of the annular partition plate 7, and one end of the two water outlet pipes 9 is connected to the top of the water cooling chamber 6 near the middle. The top of the cooling tower 3 is connected with a connecting pipe 10, and one end of the connecting pipe 10 away from the cooling tower 3 is connected with two water outlet pipes 9. Water inlet pipes 14 are symmetrically arranged on both sides of the bottom of the annular partition 7, and one end of the two water inlet pipes 14 is respectively connected with the two sides of the bottom of the water-cooling cavity 6, and the water inlet pipe 14 is connected with the cooling tower 3 through a water pump 11. When working, when the grinding cylinder 2 is in a grinding state, the cooling water can circulate between the grinding cavity and the cooling tower 3 through the water pump 11, the outlet pipe 9, the connecting pipe 10 and the water inlet pipe 14, and the cooling water can be sucked by the cooling tower 3. The cooling water that has absorbed the heat of the grinding cylinder 2 is quickly cooled down. The water cooling chamber 6 is effectively divided into two areas by adopting the annular partition 7. Combined with the two spiral partitions 8, the cooling water can be diverted and enter the two parts of the water cooling chamber 6 respectively, so as to realize the segmented heat dissipation of the grinding cylinder 2, avoid the cooling water from flowing in the water cooling chamber 6 for a long time, and to a certain extent slow down the trend of the cooling water heat dissipation efficiency decreasing in the subsequent flow path, which effectively solves the problem in the prior art that the grinding cylinder 2 of the sand mill is generally equipped with a water cooling circulation system, but the water cooling chamber 6 in most grinding cylinders 2 is It is a one-stage type, which results in that after the cooling water enters the water-cooling chamber 6, the heat dissipation efficiency on the subsequent flow path is greatly reduced compared to the heat dissipation efficiency on the initial flow path. The temperature distribution in the entire grinding cylinder 2 is uneven, presenting a multi-gradient type. In addition, the existing water-cooling circulation system cannot quickly cool down the cooling water after absorbing heat. Combined with the one-stage water-cooling chamber 6 flow structure, the grinding cylinder 2 will have an overly high temperature after working for a long time, which will cause the grinding efficiency to decrease, the properties of the material to change, and the overall performance of the material and the grinding effect to be affected.

[0022] The cooling tower 3 is composed of an annular cone cylinder 1 21 and an annular cone cylinder 22. A spiral water flow plate 1 24 is fixedly connected to the inner wall of the annular cone cylinder 1 21. The spiral water flow plate 1 24 is evenly provided with grooves 1.

A water pump 11 is fixedly connected to the bottom of the water storage cylinder 30, and 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 the connecting pipe 2 12. When working, when the cooling water that absorbs the heat of the grinding cylinder 2 enters the annular cone cylinder 21 from the water cooling chamber 6 through the water outlet pipe 9 and the connecting pipe 10, After entering the annular cone cylinder 22, it is discharged from the connecting pipe 3 28 and the connecting pipe 4 29 after slow flow and cooling, and then is sent back into the water cooling chamber 6 by the water pump 11 in cooperation with the connecting pipe 2 12 and the water inlet pipe 14 to complete the circulation flow. The cooling tower 3 composed of the annular cone cylinder 1 21 and the annular cone cylinder 22 cooperates with the spiral water flow plate 1 24 and the spiral water flow plate 2 25 designed therein, thereby increasing the contact area between the cooling water and the inner wall of the cooling tower 3, so that the heat absorbed by the cooling water can be transferred to the external environment more quickly through the annular cone cylinder 1 21 and the annular cone cylinder 22, thereby improving the heat dissipation efficiency. The groove 1 on the spiral water flow plate 1 24 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, thereby improving the heat dissipation coefficient and the heat transfer efficiency. At the same time, due to the increased interference and mixing of the cooling water, it is helpful to destroy the conditions for scale formation, thereby avoiding the formation of scale inside the cooling tower 3 and affecting the heat transfer.

[0023] A heat sink 26 is fixedly connected to the inner wall of the annular cone 1 21, a heat sink 27 is fixedly connected to the outer wall of the annular cone 22, and a plurality of fans 23 are installed on the upper part of the annular cone 1 21; when working, the heat sink 26 and the heat sink 27 are respectively provided on the annular cone 1 21 and the annular cone 2 22, so that the cooling water can transfer the absorbed heat to the outside more quickly when flowing through, and the heat accumulated in the heat sink 26 and the heat sink 27 can be quickly taken away by the fan 23, so that the heat sink 26 and the heat sink 27 can dissipate heat more effectively.

[0024] A fixed frame 4 is fixedly connected in the water storage tank 5. The fixed frame 4 is hollow. A cooling plate 13 is fixedly connected 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 chamber 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 pumping pipe 15. A main pipe 18 is fixedly connected to one side of the top of the fixed frame 4. The main pipe 18 is connected to the water pump 16 through a water supply pipe 17. A plurality of branch pipes 19 are connected to the main pipe 18. The bottom of the branch pipe 19 is provided with a spray nozzle. head, and multiple branch pipes 19 are evenly distributed above the cooling plate 13; when working, when the water pump 11 pumps the cooling water after the heat dissipation of 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 water storage tank 5 into the main pipe 18 through the pumping pipe 15 and the water delivery pipe 17, and then sprays it out from the multiple branch pipes 19 on the main pipe 18, forming a spray on the cooling plate 13, and further cools the cooling water flowing through the cooling plate 13. The sprayed water is scattered into the water storage tank 5, and is sucked by the water pump 2 16 again after slowly flowing in the water storage tank 5 to dissipate heat, forming a circulating spray on the cooling plate 13.

[0025] The cooling plate 13 is serpentine-shaped, and through holes 20 are evenly opened on the cooling plate 13. When working, by designing the cooling plate 13 to be serpentine-shaped, not only the cooling water can flow slowly in the cooling plate 13, but also the contact area between the cooling water and the cooling plate 13 is increased, which is convenient for the water sprayed by the branch pipe 19 to cool the cooling plate 13. By opening the through holes 20 on the cooling plate 13, part 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 fixed frame 4, and the other part can only flow down layer by layer from the through holes 20 on the cooling plate 13, so as to better absorb the heat transferred from the cooling water to the surface of the cooling plate 13.

[0026] A fixed platform 33 is provided at the bottom of the cooling tower 3, and the fixed platform 33 is fixedly connected to the body 1. A gear 2 34 is rotatably connected to the fixed platform 33.

A reset component is provided between the bottom of the gear 2 34 and the fixed platform 33, and a cleaning component is provided on the top of the gear 2 34; during operation, after the heat sink 1 26 and the heat sink 27 have been used for a long time, the motor 31 drives the gear 1 32 to rotate, so that the gear 2 34 drives the cleaning component to rotate accordingly, and the cleaning of the heat sink 1 26 and the heat sink 27 is completed, so that the dust attached to the heat sink 1 26 and the heat sink 27 can be avoided to affect the heat transfer efficiency. The cleaning component can be reset after rotating a certain angle through the reset component, which can not only achieve the effect of reciprocating cleaning, but also avoid interference between the cleaning component and the connecting pipe 3 28 and the connecting pipe 4 29.

[0027] The reset assembly includes a spring 1 36 and a slider 37. The bottom of the gear 2 34 is evenly fixed with the slider 37. The top of the fixed platform 33 is evenly provided with an arc groove 35. The slider 37 is slidably connected to the arc groove 35. The spring 1 36 is fixed between the slider 37 and the inner wall of the arc groove 35. The gear 1 32 is provided with teeth. During operation, since the gear 1 32 is provided with teeth, after the gear 1 32 meshes with the gear 2 34 during the rotation process, the gear 2 34 drives the slider 37 to slide in the arc groove 35 and compress the spring 1 36 until the gear 1 32 is disengaged from the gear 2 34. The slider 37 drives the gear 2 34 to reset under the elastic force of the spring 1 36. During this process, multiple cleaning assemblies cooperate to complete the reciprocating cleaning of the heat sink 1 26 and the heat sink 2 27.

[0028] The brush cleaning assembly includes a rotating rod 39 and a brush plate 43. The top of the gear 2 34 is evenly connected to a plurality of rotating rods 39.

An electromagnetic control unit is provided between the mounting block 42 and the brush plate 43. During operation, when dust cleaning is required, the brush plate 43 is controlled to slide toward the heat sink 1 26 and the heat sink 27 by turning on the electromagnetic control unit, and the reciprocating rotation cleaning is completed in cooperation with the motor 31 and the reset assembly. When the dust cleaning is completed, the electromagnetic control unit is turned off to keep the brush plate 43 away from the heat sink 1 26 and the 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. The fixed sleeve 44 is fixedly connected to both sides of the mounting block 42. The electromagnet 45 is fixedly connected to the inner cavity wall of the fixed sleeve 44. The permanent magnet 46 is slidably connected in the inner cavity of the fixed sleeve 44.

One end of the connecting block 48 away from the permanent magnet 46 extends to the outside of the fixed sleeve 44 and is fixed to the brush plate 43. The connecting block 48 is slidably connected to the outer wall of the fixed sleeve 44; during operation, when the electromagnet 45 is energized, a magnetic attraction is generated between the electromagnet 45 and the permanent magnet 46, so that the permanent magnet 46 slides toward one side of the electromagnet 45 while compressing the spring 2 47, and drives the brush plate 43 to approach the heat sink 1 26 and the heat sink 27. When the electromagnet 45 is de-energized, the permanent magnet 46 is reset under the elastic force of the spring 2 47, and the brush plate 43 is away from the heat sink 1 26 and the heat sink 27.

[0030] A gear 38 is fixedly connected to the outer top of the annular cone 22, and a gear 40 is fixedly connected to the top of the rotating rod 39. The gear 38 is meshed with the gear 40.

A reciprocating thread groove is provided on the rotating rod 39. The mounting block 42 is threadedly connected to the reciprocating thread groove. The mounting block 42 is slidably connected to the limiting rod 41. When working, when the gear 2 34 rotates under the drive of the motor 31, the rotating rod 39 drives the gear 40 to move circumferentially, and the gears 38 and 40 are meshed with each other. Wheel four 40 meshes with gear three 38 and drives the rotating rod 39 to rotate, so that the mounting block 42 sliding with the limit rod 41 slides back and forth along the reciprocating threaded groove on the rotating rod 39, and then cooperates with the electromagnetic control unit so that the brush plate 43 can not only rotate back and forth for cleaning, but also slide back and forth up and down for cleaning, thereby further improving the cleaning effect. In addition, when the brush plate 43 is away from the heat sink 1 26 and the heat sink 27, the up and down reciprocating sliding can drive the bristles on the brush plate 43 to shake, thereby shaking off the dust attached during the cleaning process.

[0031] Working principle: when the grinding cylinder 2 is in a grinding state, the cooling water can circulate between the grinding chamber and the cooling tower 3 through the water pump 11, the water outlet pipe 9, the connecting pipe 10, the water storage cylinder 30, the connecting pipe 2 12, the cooling plate 13 and the water inlet pipe 14. The cooling water that has absorbed the heat of the grinding cylinder 2 can be quickly cooled down through the cooling tower 3. The water cooling chamber 6 is effectively divided into two areas by adopting the annular partition 7. Combined with the two spiral partitions 8, the cooling water can be diverted and enter the two parts of the water cooling chamber 6 respectively, so as to realize the segmented heat dissipation of the grinding cylinder 2, avoid the cooling water from flowing in the water cooling chamber 6 for a long time, and slow down the trend of the cooling water heat dissipation efficiency decreasing in the subsequent flow path to a certain extent. When the grinding cylinder 2 is absorbed, the cooling water can be cooled down quickly by the cooling tower 3. After the cooling water of the cylinder 2 enters the annular cone cylinder 1 21 and the annular cone cylinder 2 22 from the water cooling chamber 6 through the outlet pipe 9 and the connecting pipe 1 10, it is discharged from the connecting pipe 3 28 and the connecting pipe 4 29 after slow flow and cooling, and then is sent back into the water cooling chamber 6 by the water pump 1 11 in conjunction with the connecting pipe 2 12, the cooling plate 13 and the water inlet pipe 14 to complete the circulation flow. The cooling tower 3 composed of the annular cone cylinder 1 21 and the annular cone cylinder 2 22 is combined with the spiral water flow plate 1 24 and the spiral water flow plate 2 25 designed therein, thereby increasing the contact area between the cooling water and the inner wall of the cooling tower 3, so that the heat absorbed by the cooling water can be transferred to the external environment more quickly through the annular cone cylinder 1 21 and the annular cone cylinder 2 22, thereby improving the heat dissipation efficiency. The groove 1 on the annular cone 21 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, thereby improving the heat dissipation coefficient and the heat transfer efficiency. At the same time, due to the increased interference and mixing of the cooling water, it is helpful to destroy the conditions for the formation of scale, thereby avoiding the formation of scale inside the cooling tower 3 and affecting the heat transfer. By respectively providing a heat sink 26 and a heat sink 27 on the annular cone 21 and the annular cone 22, the cooling water can transfer the absorbed heat to the outside more quickly when flowing through, and the fan 23 can quickly take away the heat accumulated in the heat sink 26 and the heat sink 27, so that the heat sink 26 and the heat sink 27 can dissipate heat more effectively. When the water pump 1 After the cooling water after the heat dissipation of the cooling tower 3 is pumped into the connecting pipe 12, the cooling water enters the cooling plate 13 from the connecting pipe 12. At this time, the water pump 16 pumps the water in the water storage tank 5 into the main pipe 18 through the pumping pipe 15 and the water delivery pipe 17, and then sprays it out from the multiple branch pipes 19 on the main pipe 18 to form a spray on the cooling plate 13, and further cools the cooling water flowing through the cooling plate 13. The sprayed water falls into the water storage tank 5, and is sucked by the water pump 16 again after slowly flowing in the water storage tank 5 to dissipate heat, forming a circulating spray on the cooling plate 13. By designing the cooling plate 13 to be serpentine, not only can the cooling water flow slowly in the cooling plate 13, but also the contact area between the cooling water and the cooling plate 13 is increased.It is convenient for the water sprayed by the branch pipe 19 to cool the cooling plate 13. By opening a through hole 20 on the cooling plate 13, a part 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 fixed frame 4, and the other part can only flow down layer by layer from the through hole 20 on the cooling plate 13, so as to better absorb the heat transferred to the surface of the cooling plate 13 by the cooling water. After the heat sink 1 26 and the heat sink 27 are used for a long time, the motor 31 drives the gear 1 32 to rotate, so that the gear 2 34 drives the cleaning component to rotate, and the cleaning of the heat sink 1 26 and the heat sink 27 is completed, so as to prevent the dust attached to the heat sink 1 26 and the heat sink 27 from affecting the heat transfer efficiency. The reset assembly allows the cleaning brush assembly to reset after rotating a certain angle, which can not only achieve the effect of reciprocating cleaning, but also avoid interference between the cleaning brush assembly and the connecting pipe three 28 and the connecting pipe four 29. Since the gear one 32 is provided with teeth, after the gear one 32 meshes with the gear two 34 during the rotation process, the gear two 34 drives the slider 37 to slide in the arc groove 35 and compress the spring one 36, until the gear one 32 is disengaged from the gear two 34, and the slider 37 drives the gear two 34 to reset under the elastic force of the spring one 36. In this process, multiple cleaning brush assemblies cooperate to complete the reciprocating cleaning of the heat sink one 26 and the heat sink two 27. When cleaning is needed, the cleaning brush assembly is opened. The electromagnetic control unit is turned on to control the brush plate 43 to slide toward the heat sink 1 26 and the heat sink 27, and cooperates with the motor 31 and the reset assembly to complete the reciprocating rotation cleaning. When the dust cleaning is completed, the electromagnetic control unit is turned off, so that the brush plate 43 is away from the heat sink 1 26 and the heat sink 27 to avoid affecting the normal heat dissipation efficiency. When the electromagnet 45 is energized, a magnetic attraction is generated between the electromagnet 45 and the permanent magnet 46, so that the permanent magnet 46 slides toward one side of the electromagnet 45 while compressing the spring 2 47, and drives the brush plate 43 to approach the heat sink 1 26 and the heat sink 27. When the electromagnet 45 is powered off, the permanent magnet 46 is reset under the elastic force of the spring 2 47, and the brush plate 43 is away from the heat sink 1 26 and the heat sink 27. Heat sink 27, when gear 2 34 rotates under the drive of motor 31, rotating rod 39 drives gear 4 40 to move circumferentially, gear 4 40 meshes with gear 3 38, and drives rotating rod 39 to rotate, so that mounting block 42 sliding with limit rod 41 slides up and down along the reciprocating thread groove on rotating rod 39, and then cooperates with electromagnetic control unit, so that brush plate 43 can not only reciprocate and rotate to clean, but also slide up and down to clean, further improving the cleaning effect. In addition, when brush plate 43 is away from heat sink 1 26 and heat sink 27, the reciprocating up and down sliding can drive the bristles on brush plate 43 to shake, and the dust attached during the cleaning process can be shaken off.
