Description

Technical Field

[0001] The utility model belongs to the technical field of sand mill equipment, and particularly relates to a cooling and noise reduction structure for a sand mill. Background Art

[0002] Sand mill, also known as bead mill, is a wet ultrafine grinding equipment developed from ball mill. The material and the grinding beads in the grinding cylinder are stirred together by the high-speed rotating disperser, so that the solid particles in the material and the grinding medium produce more intense collision, friction and shearing effects with each other, so as to accelerate the grinding of particles and disperse aggregates. The material will make a lot of noise during the collision and friction process in the grinding cylinder, which seriously affects the normal work of the operators in the workshop. In addition, the grinding equipment will generate a lot of heat during the grinding process, and the temperature will rise significantly, which will cause the material to agglomerate, resulting in grinding difficulties. Some materials are sensitive to temperature, and high temperature will have a bad effect on the material properties. Utility Model Content

[0003] The purpose of the utility model is to provide a cooling and noise reduction structure for a sand mill with a simple structure and reasonable design in order to solve the above problems.

[0004] The utility model achieves the above-mentioned purpose through the following technical solutions:

[0005] A cooling and noise reduction structure for a sand mill includes a base, on which a sand mill body is mounted, a grinding cylinder connected to the right end of the sand mill body, a noise reduction mechanism provided on the grinding cylinder, the noise reduction mechanism including an upper arc plate and a lower arc plate, sound insulation cotton connected to the inner walls of the upper and lower arc plates, a cooling mechanism provided between the grinding cylinder and the sand mill body, the cooling mechanism including a cooling cylinder, the cooling cylinder being sleeved on the outer wall of the grinding cylinder, the sound insulation cotton being tightly attached to the outer wall of the cooling cylinder, and water pipes spirally arranged inside the wall thickness of the cooling cylinder.

[0006] As a further optimization scheme of the present invention, connecting plates are connected to the corresponding positions of the lower end of the upper arc plate and the upper end of the lower arc plate, and the two connecting plates are fixedly connected by screws. A support leg is connected to the lower side of the outer wall of the lower arc plate, and the other end of the support leg is connected to a shock-absorbing buffer column.

[0007] As a further optimization solution of the present invention, the shock-absorbing buffer column includes a receiving plate, the receiving plate is connected to the supporting leg, the lower end of the receiving plate is connected to a spring, the spring outer cover has a buffer support, and the buffer support is connected to the base.

[0008] As a further optimization scheme of the present invention, the lower end of the water pipe is connected to a water pump, the lower end of the water pump is connected to a water tank, a refrigerator is installed at the lower end of the water tank, and a collection box is placed at the corresponding position on the lower side of the other end of the water pipe. The collection box is connected to the water tank through a pipeline, and the position of the collection box is slightly higher than that of the water tank.

[0009] As a further optimization solution of the present invention, the water tank is installed between the sand mill body and the grinding cylinder, and the collection box is located on the right side of the grinding cylinder.

[0010] As a further optimization solution of the present invention, a grinding roller is rotatably connected in the grinding cylinder, the grinding roller passes through the left end of the grinding cylinder and is connected to a connecting shaft, and the left end of the connecting shaft is connected to the driving mechanism in the sand mill body.

[0011] The beneficial effects of the present invention are:

[0012] 1. The utility model reduces the noise generated by the sand mill during operation by using two arc plates connected to the sander body in conjunction with sound insulation cotton. At the same time, the use of shock-absorbing buffer columns at the lower ends of the supporting legs in the noise reduction mechanism blocks the propagation of noise in the air, thereby achieving the effect of shock absorption and noise reduction of the sand mill, ensuring that the sand mill does not make too much noise during the grinding process of materials, and protecting the health of operators.

[0013] 2. The utility model uses a water pump to transport the water in the water tank into the water pipe. Since the cooling cylinder is tightly attached to the outer wall of the grinding cylinder, the water flow takes away the temperature of the grinding cylinder and cools the grinding cylinder, which will not cause the material to agglomerate, avoid causing grinding difficulties, and prevent the material being ground in the grinding cylinder from changing its properties due to high temperature due to excessive temperature. At the same time, the heat generated by the driving device in the sand mill body is discharged from the heat dissipation port by the heat dissipation fan, ensuring that the sand mill can work normally and continuously.

[0021] Example

[0023] The lower end of the upper arc plate 41 and the upper end of the lower arc plate 42 are connected to a connecting plate 45 at corresponding positions, and the two connecting plates 45 are fixedly connected by screws 46. The lower side of the outer wall of the lower arc plate 42 is connected to a supporting leg 47, and the other end of the supporting leg 47 is connected to a shock-absorbing buffer column 48. The shock-absorbing buffer column 48 includes a receiving plate 481, which is connected to the supporting leg 47. The lower end of the receiving plate 481 is connected to a spring 482, and the outer cover of the spring 482 is provided with a buffer support 483. The buffer support 483 is connected to the base 1, which can just achieve the effect of noise reduction and vibration reduction. The lower end of the water pipe 52 is connected to a water pump 53, and the lower end of the water pump 53 is connected to a water tank 54. A cooler 55 is installed at the lower end of the water tank 54. A collecting box 56 is placed at the corresponding position on the lower side of the other end of the water pipe 52. The collecting box 56 is connected to the water tank 54 through a pipe 57. The position of the collecting box 56 is slightly higher than the position of the water tank 54. The water tank 54 is installed between the sand grinder body 2 and the water tank 54. Between the grinding cylinders 3, the collecting box 56 is located on the right side of the grinding cylinder 3. When the cooling mechanism 5 cools the grinding cylinder 3, it first controls the water pump 53 to work. The water pump 53 transports the water in the water tank 54 to the water pipe 52. The water flow in the water pipe 52 takes away the heat generated by the grinding cylinder 3 during operation, thereby achieving the effect of cooling the grinding cylinder 3. At the same time, the cooling water is collected and transported to the water tank 54 again through the pipe 57. After the refrigerator 55 works, it is used again to cool the cylinder wall, saving water resources. A grinding roller 8 is rotatably connected in the grinding cylinder 3. The grinding roller 8 passes through the grinding cylinder 3 and is connected to a connecting shaft 9 at the left end. The connecting shaft 9 passes through the rotating cooling fan 51. The left end of the connecting shaft 9 is connected to the driving mechanism in the sand mill body 2. When the driving device is working, it drives the connecting shaft 9 connected to its output end to rotate, so that the grinding roller 8 rotates in the grinding cylinder 3 to grind the material.

[0024] During use, first control the driving device in the sand mill body 2 to work. When the driving device is working, it drives the connecting shaft 9 connected to its output end to rotate, so that the grinding roller 8 rotates in the grinding cylinder 3 to grind the material. Then control the water pump 53 to work. The water pump 53 transports the water in the water tank 54 to the water pipe 52. The water flow in the water pipe 52 takes away the heat generated by the grinding cylinder 3 during operation, thereby achieving the effect of cooling the grinding cylinder 3. At the same time, the cooling water is collected and transported to the water tank 54 again through the pipe 57. After the refrigerator 55 works, it is used again to cool the cylinder wall, saving water resources. When the material is ground, the noise generated by the collision and friction of the material in the grinding cylinder 3 is absorbed by the two arc plates connected to the sander body and the sound insulation cotton 43, blocking the noise from propagating in the air. At the same time, the use of the shock-absorbing buffer column 48 at the lower end of the support leg 47 in the noise reduction mechanism 4 is used to achieve the effect of shock and noise reduction of the sand mill.

[0025] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the scope of the present invention, all of which fall within the scope of protection of the present invention.
