Description

Technical Field

[0001] This utility model relates to the field of sand mill technology, and in particular to a high-efficiency and energy-saving sand mill. Background Technology

[0002] A sand mill is a device used for grinding and dispersing materials. The sand mill uses a high-speed rotor to generate shearing, impact, and crushing forces in the grinding media, which disperses, crushes, grinds, deagglomerates, homogenizes, and emulsifies granular materials. The material is sent into the main grinding tank by a feed pump, and an appropriate amount of grinding media is added. The rotation of the main shaft gives the grinding media kinetic energy, and the material particles collide to generate shearing, mixing, and emulsification. The material is then discharged by a separation device, achieving fineness and dispersion effects.

[0003] Traditional sand mills typically feed materials directly into the mill via a feed pump. However, when dealing with materials containing large particles of varying sizes, the lack of pre-treatment of these large particles means that the milling media often takes significantly longer to process them. For example, in the sand milling of some chemical raw materials, large impurities may be repeatedly ground within the mill, greatly extending the overall milling process. Furthermore, directly feeding materials mixed with large particles into the mill can lead to incomplete and uneven grinding. Due to the presence of large particles, the milling media may struggle to evenly distribute the material across each particle, resulting in some areas being over-ground while others around or within the large particles remain under-ground, ultimately affecting the quality of the final product. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a high-efficiency and energy-saving sand mill.

[0005] This utility model is achieved using the following technical solution: a high-efficiency and energy-saving sand mill, comprising a worktable, a mounting base fixedly connected to the upper surface of the worktable, a grinding cylinder disposed inside the mounting base, a support column fixedly connected to the upper surface of the worktable, a top plate fixedly connected to the upper surface of the support column, a grinding frame fixedly connected to the upper surface of the top plate, a positioning grinding roller rotatably connected to the inner wall of the grinding frame, a sliding groove provided on the inner wall of the grinding frame, a slide frame slidably connected inside the sliding groove, an electric push rod fixedly connected to the inner wall of the top plate, a transverse groove provided on the surface of the top plate, a motor base slidably connected inside the transverse groove, a grinding motor fixedly mounted on the surface of the motor base, and a movable grinding roller fixedly connected to the output end of the grinding motor through the slide frame.

[0006] The above technical solution allows for pre-grinding based on particle size, reducing subsequent grinding time and improving grinding efficiency. Furthermore, the spacing between the grinding rollers can be adjusted as needed to accommodate materials of different sizes.

[0007] As a further improvement to the above solution, the electric push rod is fixedly connected to the surface of the slide, and the movable grinding roller is rotatably connected to the inner wall of the grinding frame.

[0008] As a further improvement to the above solution, a discharge groove is provided on the lower surface of the grinding frame.

[0009] As a further improvement to the above solution, a feeding pipe is fixedly connected to the lower surface of the top plate, and the feeding pipe is located below the discharge trough.

[0010] Through the above technical solution, the feed pipe plays a role in material transmission, ensuring that the material is smoothly transferred from the grinding frame to the feeding position of the grinding cylinder, avoiding material spillage and improving the continuity of processing.

[0011] As a further improvement to the above solution, a feed groove is provided on the surface of the grinding cylinder, and the feed pipe is fixedly connected to the inside of the feed groove.

[0012] As a further improvement to the above solution, a sleeve is fixedly connected to the upper surface of the worktable, and a drive motor is fixedly connected inside the sleeve.

[0013] As a further improvement to the above solution, the output end of the drive motor is fixedly connected to a grinding disc, which is rotatably connected to the inside of the grinding cylinder.

[0014] The above technical solution realizes the grinding function of materials inside the grinding cylinder, and the grinding media effectively grinds the materials by rotating the grinding disc.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This invention uses an electric push rod to move a slide, which in turn moves a grinding motor and a movable grinding roller. The motor base moves along a transverse groove to adjust the distance between the positioning grinding roller and the movable grinding roller. Personnel can flexibly adjust the distance according to the particle size requirements of different materials, so that large particles can be effectively crushed. Through the rotation and squeezing action of the positioning grinding roller and the movable grinding roller, large-volume materials can be pre-crushed into smaller-volume materials, ensuring that the particle size of the materials entering the subsequent grinding process will not differ too much, reducing the workload of subsequent grinding in the grinding cylinder, and avoiding the problem of excessively long grinding time or incomplete grinding caused by large particles directly entering the grinding cylinder.

[0026] Please combine Figure 1-5This embodiment of a high-efficiency and energy-saving sand mill includes a worktable 1, a mounting base 2 fixedly connected to the upper surface of the worktable 1, a grinding cylinder 3 disposed inside the mounting base 2, a support column 4 fixedly connected to the upper surface of the worktable 1, a top plate 5 fixedly connected to the upper surface of the support column 4, a grinding frame 6 fixedly connected to the upper surface of the top plate 5, a positioning grinding roller 7 rotatably connected to the inner wall of the grinding frame 6, a sliding groove 8 formed on the inner wall of the grinding frame 6, a slide frame 9 slidably connected inside the sliding groove 8, an electric push rod 10 fixedly connected to the inner wall of the top plate 5, a transverse groove 11 formed on the surface of the top plate 5, a motor base 12 slidably connected inside the transverse groove 11, and a grinding motor 13 fixedly mounted on the surface of the motor base 12. The output end of the grinding motor 13 is fixedly connected to the movable grinding roller 14 through the slide 9. The personnel adjust the distance between the positioning grinding roller 7 and the movable grinding roller 14 according to the needs. First, the two grinding rollers are used to grind large particles of material. Then, the ground material is sent into the grinding cylinder 3 for sand grinding. The electric push rod 10 is started. The electric push rod 10 pushes the slide 9 to move along the sliding groove 8. When the slide 9 moves, the motor base 12 and the grinding motor 13 move along the transverse groove 11 to adjust the position. After the distance is adjusted, the grinding motor 13 is started to drive the movable grinding roller 14 to rotate. The material is poured in. The material smaller than the distance directly enters the grinding cylinder 3. The large volume material is squeezed by the movable grinding roller 14 and crushed into small volume material in cooperation with the positioning grinding roller 7.

[0027] The electric push rod 10 is fixedly connected to the surface of the slide 9, and the movable grinding roller 14 is rotatably connected to the inner wall of the grinding frame 6. The electric push rod 10 is fixedly connected to the surface of the slide 9, so that the electric push rod 10 can effectively push the slide 9 to move; the movable grinding roller 14 is rotatably connected to the inner wall of the grinding frame 6 to ensure the stability when the grinding motor 13 drives the movable grinding roller 14 to rotate.

[0028] The lower surface of the grinding frame 6 is provided with a discharge groove 15, through which the ground material and smaller volume materials are discharged.

[0029] A feeding pipe 16 is fixedly connected to the lower surface of the top plate 5. The feeding pipe 16 is located below the discharge trough 15. The feeding pipe 16 fixedly connected to the lower surface of the top plate 5 is located below the discharge trough 15 and is used to receive the material discharged from the discharge trough 15.

[0030] The surface of the grinding cylinder 3 is provided with a feed groove 17, and the feed pipe 16 is fixedly connected to the inside of the feed groove 17.

[0031] A sleeve 18 is fixedly connected to the upper surface of the workbench 1, and a drive motor 19 is fixedly connected inside the sleeve 18.

[0032] The output end of the drive motor 19 is fixedly connected to the grinding disc 20. The grinding disc 20 is rotatably connected to the inside of the grinding cylinder 3. When the material enters the inside of the grinding cylinder 3 through the feed pipe 16, the drive motor 19 drives the grinding disc 20 to rotate, so that the grinding media inside the grinding cylinder 3 performs grinding work on the material.

[0033] The implementation principle of a high-efficiency and energy-saving sand mill in this embodiment is as follows: First, the operator adjusts the distance between the positioning grinding roller 7 and the movable grinding roller 14 according to the characteristics of the material to be ground and the sand grinding requirements. During this process, since the electric push rod 10 is fixedly connected to the surface of the slide 9, the operator starts the electric push rod 10, which pushes the slide 9 to move along the sliding groove 8 on the inner wall of the grinding frame 6. As the slide 9 moves, the grinding motor 13, which is fixed on the slide 9 and passes through the slide 9, drives the movable grinding roller 14 to move. At this time, the motor base 12 and the grinding motor 13 move along the transverse groove 11 of the top plate 5, thereby realizing the adjustment of the distance with the positioning grinding roller 7. The movable grinding roller 14 is rotatably connected to the inner wall of the grinding frame 6 to ensure the stability of the rotation. Then, after the distance adjustment is completed, the operator starts the grinding motor 13, which drives the movable grinding roller 14 to rotate. Then, the material is poured between the positioning grinding roller 7 and the movable grinding roller 14. At this time, the material smaller than the distance between the two grinding rollers will be... The material enters the grinding cylinder 3 directly. For large-volume materials, the movable grinding roller 14 will squeeze them, while the positioning grinding roller 7 rotates. The two work together to break the large particles into smaller ones. After grinding, the ground material and the smaller particles are discharged through the discharge trough 15 on the lower surface of the grinding frame 6. Since the lower surface of the top plate 5 is fixedly connected to the discharge pipe 16, and the discharge pipe 16 is located below the discharge trough 15, the material falls into the discharge pipe 16. The discharge pipe 16 is fixedly connected to the feed trough 17 on the surface of the grinding cylinder 3, and the material then enters the grinding cylinder 3. Finally, when the material enters the grinding cylinder 3, the upper surface of the worktable 1 is fixedly connected to the sleeve 18, and the sleeve 18 is fixedly connected to the drive motor 19. The output end of the drive motor 19 is fixedly connected to the sand grinding disc 20, which is rotatably connected to the inside of the grinding cylinder 3. The operator starts the drive motor 19, which drives the sand grinding disc 20 to rotate, so that the sand grinding media inside the grinding cylinder 3 grinds the material.

Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
