Description

Technical Field

[0001] The invention relates to the technical field of sand mills, in particular to a low-loss sand mill. Background Art

[0002] The sand mill grinds the material through the friction and collision of the grinding media in the grinding cylinder. Specifically, the grinding cylinder contains a certain proportion of grinding media and the material to be ground. The motor drives the reducer to rotate, so that the media and materials in the grinding cylinder are constantly rolling, grinding, and mixing. There will be strong collision, friction and shearing between the material and the grinding media, thereby achieving the purpose of accelerating the grinding of fine particles and dispersing agglomerates. At the same time, due to the centrifugal separation effect generated by the rotor, the sand milling media is separated from the material, and the ground material flows into the receiving container from the centrifugal filter gap with the help of the feed pump, while the sand milling media remains in the sand mill cavity to continue grinding the coarse particles in the slurry.

[0003] When grinding materials, the existing sand mill generates high heat due to internal friction, which causes great loss to the internal grinding media and grinding parts during grinding, so the service life is not long. Using other cooling equipment to assist will also consume more energy. Summary of the invention

[0004] In order to solve the above technical problems, the object of the present invention is to provide a sand mill which can reduce energy consumption and increase the life of grinding parts.

[0005] In order to achieve the above object, the technical solution of the present invention is as follows: a low-loss sand mill, comprising: A sand mill body, the sand mill body comprising a grinding cylinder and a jacket body, the jacket body is coaxially sleeved on the outside of the grinding cylinder, and a cavity is provided inside the jacket body; A base, wherein a vibrating placement plate is slidably connected inside the base, a placement cavity is provided between the placement plate and the base, cooling fluid medium is provided inside the placement cavity and the cavity, the placement cavity and the cavity are connected by a connecting piece, the sand mill body is placed on the base, and the vibration generated by the sand mill body grinding the material can drive the cooling fluid medium to circulate.

[0006] The beneficial effect of the present invention is that by arranging the connecting piece and the vibrating placement plate, when the sand mill body grinds the material, the vibration generated during the grinding will drive the placement plate to vibrate, and when the placement plate vibrates, it will produce an extrusion effect on the cooling fluid medium. After the cooling fluid medium located inside the base is squeezed, it flows into the gap between the jacket body and the grinding cylinder, thereby realizing the circulation and cooling of the cooling fluid medium between the jacket body and the grinding cylinder.

[0007] Based on the above technical solution, the present invention can also be improved as follows.

[0013] By adopting the above scheme, the spring bar and the telescopic rod are used to realize the vibration of the device on the base, and at the same time, the vibration direction of the sand mill body can be limited so that it can always vibrate along the vertical direction.

[0016] Furthermore, the grinding cylinder is provided with a feed pipe, the feed pipe passes through the jacket body, the feed pipe is communicated with the grinding cylinder, and a resonance stirring component is provided inside the feed pipe for stirring the material when the material enters the feed pipe.

[0022] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0023] Example like Figure 1-5 As shown, a low-loss sand mill comprises: A sand mill body 1, the sand mill body 1 comprises a grinding cylinder 11 and a jacket body 12, the jacket body 12 is coaxially sleeved outside the grinding cylinder 11, and a cavity 121 is provided inside the jacket body 12; A base 2, wherein a vibrating placement plate 21 is slidably connected inside the base 2, a placement cavity 22 is provided between the placement plate 21 and the base 2, a cooling fluid medium 23 is provided inside the placement cavity 22 and the cavity 121, and the placement cavity 22 and the cavity 121 are connected via a connecting piece 24, the sand mill body 1 is placed on the base 2, and the vibration generated by the sand mill body 1 when grinding the material can drive the cooling fluid medium 23 to circulate.

[0024] The above technical solution can be realized by setting a connecting piece 24 and a vibrating placement plate 21. When the sand mill body 1 grinds the material, the vibration generated during grinding will drive the placement plate 21 to vibrate. When the placement plate 21 vibrates, it will produce an extrusion effect on the cooling fluid medium 23. After the cooling fluid medium 23 inside the base 2 is squeezed, it flows into the gap between the jacket body 12 and the grinding cylinder 11, thereby realizing the circulation of the cooling fluid medium 23 between the jacket body 12 and the grinding cylinder 11 for cooling. In addition, it can be obtained that when the cooling fluid medium 23 is arranged inside the jacket body 12, due to the vibration of the grinding machine body, the cold zone fluid medium can effectively absorb the vibration, thereby reducing the noise generated by the device during operation.

[0025] Preferably, the connecting member 24 comprises: A first connecting tube 241, one end of which is assembled below the jacket body 12, and the other end of which is communicated with the placement cavity 22; A second connecting pipe 242 , one end of which is assembled on the top of the jacket body 12 , and the other end of which is communicated with the placement cavity 22 through a refrigeration box assembly 243 .

[0026] The above technical solution can utilize the first connecting pipe 241 and the second connecting pipe 242 to realize the circulation of the cooling fluid medium 23 inside the jacket body 12 outside the device, thereby improving the cooling circulation effect of the jacket body 12 .

[0027] Preferably, the vertical distance d1 between the first connecting pipe 241 and the lower end of the water bath jacket body 12, the vertical distance d3 between the second connecting pipe 242 and the lower end of the water bath jacket body 12, and the vertical distance d2 between the liquid surface of the cooling fluid medium 23 and the lower end of the water bath main jacket body 12 satisfy: d1<d2<d3.

[0028] The above technical solution can limit the vertical distance between the first connecting pipe 241 and the lower end of the water bath jacket body 12, the vertical distance between the second connecting pipe 242 and the lower end of the water bath jacket body 12, and the vertical distance between the liquid surface of the cooling fluid medium 23 and the lower end of the water bath main jacket body 12, so that when the device vibrates, the water inside the water bath jacket body 12 can be intermittently squeezed to return the water inside the water bath jacket body 12 to the placement cavity 22 inside the base 2 through the second connecting pipe 242, so that the device can realize the circulation of the cooling fluid medium 23 by means of the self-vibration of the sand mill during grinding.

[0029] Preferably, a plurality of elastic telescopic members 244 are provided on the inner wall of the bottom end of the base 2, and the elastic telescopic members 244 include: A fixed hollow tube 2441, the lower end of which is connected and fixed to the inner wall of the bottom end of the base 2; A telescopic rod 2442, one end of which is arranged inside the fixed hollow tube 2441 and is slidably sealed along the length direction of the fixed hollow tube 2441, and the other end extends to the outside of the fixed hollow tube 2441 and is connected and fixed to the placement plate 21, and a spring bar is fixedly connected between one end of the telescopic rod 2442 and the inner wall of the bottom end of the base 2.

[0030] The above technical solution can utilize the spring bar and the telescopic rod 2442 to realize the vibration of the device on the base 2 while limiting the vibration direction of the sand mill body 1 so that it can always vibrate in the vertical direction.

[0031] Preferably, the refrigeration box assembly 243 includes: A refrigeration box 2431, the refrigeration box 2431 is mounted on one side of the base 2, a one-way valve 2433 is provided on the inner wall of one side of the lower end of the refrigeration box 2431 close to the base 2, and the refrigeration box 2431 is connected to the placement cavity 22 through the one-way valve 2433, and a fixed pipe 2434 is provided on the inner wall of one side of the upper end of the refrigeration box 2431 away from the base 2, and the fixed pipe 2434 is connected to the second connecting pipe 242; The refrigeration fin 2432 is installed on the outside of the refrigeration box 2431 and is used to refrigerate the cooling fluid medium 23 inside the refrigeration box 2431.

[0032] The above technical solution sets a refrigeration box 2431 and a refrigeration plate 2432. When the cooling fluid medium 23 circulates, the cooling fluid medium 23 can enter the refrigeration box 2431 during recycling, thereby reducing the temperature of the cooling fluid medium 23, thereby always ensuring the heat exchange effect of the sand mill body 1.

[0033] Preferably, the grinding cylinder 11 is provided with a feed pipe 111, the feed pipe 111 passes through the jacket body 12, the feed pipe 111 is communicated with the grinding cylinder 11, and a resonance stirring assembly 112 is provided inside the feed pipe 111 for stirring the material when the material enters the feed pipe 111.

[0034] By adopting the above technical solution and setting a resonance stirring component 112 in the discharge pipe 111, when the material enters the discharge pipe 111, the resonance stirring component 112 can continuously pre-stir the material as the sand mill body 1 vibrates, thereby avoiding congestion of the material in the discharge pipe 111.

[0035] Preferably, the resonance stirring assembly 112 comprises: An elastic rope 1121, wherein the elastic rope 1121 is transversely mounted on the inner wall of the feeding tube 111; The counterweight block 1122 is assembled on the elastic rope 1121 .

[0036] By adopting the above technical solution, by combining the elastic rope 1121 and the counterweight 1122, the counterweight 1122 can vibrate continuously with the vibration caused by grinding when the sand mill body 1 is working, so that the counterweight 1122 can stir and crush the material in the discharge pipe 111 to avoid material congestion.

[0037] In summary, when the device is grinding the material, the sand mill body 1 is arranged in the base 2. Due to the vibration generated when grinding the material, the sand mill body 1 can continuously vibrate in the placement cavity 22 of the base 2, thereby squeezing the cooling fluid medium 23 in the placement cavity 22. When the sand mill body 1 is pressed down, the cooling fluid medium 23 is squeezed and enters the inside of the jacket body 12 through the first connecting pipe 241. The liquid level of the cooling fluid medium 23 in the jacket body 12 rises, and then flows back to the placement cavity 22 from the second connecting pipe 242, thereby utilizing the vibration generated by the sand mill body 1 during operation to realize the circulation of the cooling fluid medium 23, thereby improving the cooling effect of the device and reducing energy consumption. In addition, filling the cooling fluid medium 23 inside the jacket body 12 can also effectively absorb the vibration generated by the device during operation, and cooperate with the cooling fluid medium 23 inside the placement cavity 22 to provide a buffering effect on the sand mill body 1, thereby reducing the noise generated by the device when grinding the material.
