[0002] Large rotary cylinders such as cement mills and tube mills all use sliding supports with strong load-bearing capacity, and sliding shoes are the key components of the structure.

[0003] After searching, the application with patent number CN201922196021.6 discloses a split tube mill sliding shoe, including a cast shoe body, a bearing alloy shoe matched with the sliding shoe surface of the cylinder, an end fixing block, and an axial fixing baffle. The two end fixing blocks are respectively fixed to the two ends of the upper end surface of the cast shoe body by block fixing bolts, the bearing alloy shoe is positioned on the upper end surface of the cast shoe body by the end fixing blocks, and the two axial fixing baffles are respectively fixed to the axial sides of the cast shoe body by baffle fixing bolts;

[0004] Although the split tube mill sliding shoe adopts a split structure, which solves the problem of poor bonding between the shoe body and the bearing Babbitt alloy, the sliding shoe of the split tube mill has poor heat dissipation effect. Frictional heat generated during equipment operation can easily cause the sliding shoe to be in a high temperature state for a long time, reducing the service life of the sliding shoe.

[0005] Therefore, we propose a mill sliding shoe for reducing internal heat. Utility Model Content

[0009] Preferably, a ventilation groove is opened in the middle of the curved surface, and the ventilation groove and the ventilation hole are interconnected. The fan is a low-speed fan, so that the outside air can enter the interior of the ventilation groove, and then the outside air enters the interior of the T-shaped tube through the ventilation hole and then is discharged, so as to increase the air circulation rate inside the ventilation groove. The fan can speed up the air circulation inside the T-shaped tube, so that a slight negative pressure is formed inside the T-shaped tube, and then the air circulation rate inside the ventilation groove is accelerated, and then the sliding shoe body is ventilated and cooled.

[0010] Preferably, evenly distributed heat dissipation fins are fixedly mounted on both sides of the top surface of the sliding shoe body, wherein the heat dissipation fins can absorb the heat inside the sliding shoe body and then dissipate the heat into the air, which is beneficial to improving the heat dissipation effect of the sliding shoe body.

[0011] Preferably, two symmetrically distributed water inlet holes are formed through the side wall tube of the sliding shoe body, wherein water is input into the water inlet holes to absorb the heat inside the sliding shoe body.

[0012] Preferably, U-shaped tubes connected to the water inlet holes are fixedly installed on the left and right sides of the sliding shoe body, wherein the water inlet holes on both sides can be connected to each other through the ventilation groove.

[0014] The utility model provides a mill sliding shoe for reducing internal heat. It has the following beneficial effects:

[0015] 1.

[0016] 2. The mill sliding shoe that reduces internal heat absorbs the heat inside the sliding shoe body through the heat dissipation fins, and then dissipates the heat into the air. The water source is input into the interior of the U-shaped tube through the connecting pipe on one side, and then the water source enters the interior of the U-shaped tube on the other side through the water inlet hole, and then is discharged into the water storage tank through the connecting pipe on the other side.
