Description

Technical Field

[0001] The utility model relates to the technical field of sand milling auxiliary equipment, in particular to a sand mill cylinder cooling device. Background Art

[0002] A sand mill is a mechanical equipment commonly used for grinding and polishing materials. It is widely used in chemical, building materials, metallurgy, electronics, ceramics and other industries. Through friction and grinding, the roughness of the material surface is reduced to achieve a smooth and bright effect. When sanding, the raw materials and sanding agent need to be poured into the sanding barrel, and then the grinding disc in the sanding barrel is used for sanding. However, the following defects may exist in actual production: When sanding, since the material is in full contact and friction with the sanding agent, and also in full contact and friction with the inner surface of the sanding barrel, friction will generate heat and increase the temperature inside the sanding barrel. Some raw materials have relevant requirements for temperature. When the temperature is too high, the raw materials will be denatured. Therefore, too high a temperature is not conducive to production.

[0014] Depend on Figures 1 to 7 It is given, including a left-right axial sanding cylinder 1, a cooling shell 2 is coaxially provided on the outer surface of the sanding cylinder 1, a containing shell 3 is coaxially provided on the right end of the cooling shell 2, a curled cooling tube 4 is provided in the containing shell 3, a liquid outlet pipe 5 inserted into the cooling shell 2 is provided at the upper end of the cooling tube 4, a suction cylinder 6 located on the inner side of the cooling tube 4 and in the left-right axial direction is provided in the containing shell 3, a piston plate 7 which can move left and right is coaxially provided in the suction cylinder 6, an L-shaped liquid suction pipe 8 inserted into the cooling shell 2 is provided at the lower end of the suction cylinder 6, and an L-shaped connecting pipe 9 inserted into the inner end of the cooling tube 4 is provided at the front end of the suction cylinder 6.

[0015] In order to enable the piston plate 7 to move left and right, the piston plate 7 is coaxially slidably connected to the suction cylinder 6, a moving column 10 is coaxially provided at the right end of the piston plate 7, a rotatable rotating tube 11 is provided in the accommodating shell 3, an annular groove 12 is provided on the inner surface of the rotating tube 11, the right end of the moving column 10 is inserted into the rotating tube 11 and is provided with an insert column 13 inserted into the annular groove 12.

[0016] In order to rotate the rotating tube 11, the rotating tube 11 is rotatably connected to the containing shell 3. A main gear 14 located on the right side of the suction cylinder 6 is coaxially provided on the rotating tube 11, and a secondary gear 15 meshing with the main gear 14 and rotatable is provided in the containing shell 3.

[0017] In order to rotate the auxiliary gear 15 , a motor is provided on the suction cylinder 6 , and the motor output shaft is coaxially and fixedly connected with the auxiliary gear 15 .

[0018] For ease of use, the cooling shell 2, the cooling pipe 4 and the suction cylinder 6 are filled with cooling liquid.

[0019] In order to facilitate the flow of the cooling liquid, a first one-way valve with an upward opening is provided in the liquid suction pipe 8, and a second one-way valve with a forward opening is provided in the connecting pipe 9.

[0020] In order to facilitate heat dissipation, the right end of the rotating tube 11 passes through the containing shell 3 and is provided with a suction fan 16 , and a plurality of suction holes 17 are opened on the right side wall of the containing shell 3 .

[0021] In order to increase the heat dissipation effect, a plurality of heat dissipation holes are provided on the containing shell 3 .

[0022] For the purpose of protection, a protective plate surrounding the suction fan 16 is provided at the right end of the accommodating shell 3 .

[0023] When the utility model is used, firstly, all the materials and the grinding agent are injected into the sand mill 1, and then the sand mill is turned on, and the sand mill starts to work and grind. After working for a period of time, the sand mill 1 starts to heat up. At this time, since the cooling shell 2 is tightly fitted with the sand mill 1, and the temperature of the coolant in the cooling shell 2 is relatively low, the coolant absorbs the heat generated by the sand mill 1, so that the temperature inside the sand mill 1 is reduced. At the same time, the motor is turned on, and the motor drives the sub gear 15 to start rotating. The sub gear 15 drives the rotating tube 11 to rotate through the main gear 14, and the rotating tube 11 is connected to the main gear 14 through the annular groove 12. The plug post 13 drives the movable post 10 to move rightward, and the movable post 10 drives the piston plate 7 to move rightward. The piston plate 7 absorbs the coolant after absorbing heat in the cooling shell 2 into the suction cylinder 6 through the suction pipe 8. The motor continues to rotate. When the plug post 13 moves to the rightmost end of the annular groove 12, the suction cylinder 6 is filled with high-temperature coolant. The motor continues to rotate, and the plug post 13 starts to move leftward in the annular groove 12 and drives the piston plate 7 to move leftward. The piston plate 7 moves leftward to squeeze the coolant inside the suction cylinder 6, and squeezes the coolant into the cooling pipe 4 through the connecting pipe 9.

[0024] When the main gear 14 drives the rotating tube 11 to rotate, it also drives the suction fan 16 to rotate. The suction fan 16 rotates to extract the heat in the containment shell 3 through the suction hole 17. At the same time, the high-temperature coolant flows in the cooling tube 4 to dissipate the heat to the inside of the containment shell 3. At this time, the suction fan 16 extracts the heat from the inside of the containment shell 3 to reduce the temperature inside the containment shell 3, and then cools the coolant in the cooling tube 4, so that the originally high-temperature coolant is converted into a low-temperature coolant. The cooled coolant in the cooling tube 4 is injected into the cooling shell 2 again through the liquid outlet pipe 5 to reduce the temperature in the cooling shell 2. The motor continues to rotate and continuously drives the piston plate 7 to move left and right. Because the high-temperature coolant in the cooling shell 2 is continuously sucked out and injected into the cooling tube 4 to achieve cooling, the suction fan 16 absorbs the heat to reduce the temperature of the coolant in the cooling tube 4, and then the cooled coolant is re-injected into the cooling shell 2;

[0025] The temperature inside the cooling shell 2 is always maintained at a relatively low temperature, there is always a temperature difference with the sand mill 1 and the heat inside the sand mill 1 is always absorbed, so that the temperature inside the sand mill 1 is maintained at a relatively low temperature to prevent the material from being denatured due to excessive temperature inside the sand mill 1. When the suction cylinder 6 absorbs the coolant, the second one-way valve can prevent the coolant in the cooling pipe 4 from being sucked into the suction cylinder 6. When the coolant is injected into the cooling pipe 4, the first one-way valve can prevent the coolant from being re-injected into the suction pipe 8. This can be repeated to cool the coolant that absorbs heat and circulate it, to prevent the internal temperature of the sand mill 1 from being too high. At the same time, the protective plate can prevent the suction fan 16 from scratching the staff.

[0026] Compared with the prior art, the utility model has the following beneficial effects: the cooling shell, cooling pipe, suction fan, etc. are provided, so that the coolant can absorb the heat generated by the sand mill and reuse it after cooling, so that the temperature inside the sand mill is always maintained at a low level, preventing the material from being denatured due to excessive temperature inside the sand mill; the protective plate is provided to prevent the suction fan from injuring the operator; the structure is simple, the concept is novel, the use is convenient, and the practicability is strong.
