[0025] Example

[0026] like Figures 1 to 4 As shown, a cooling device for a paint sand mill comprises a grinding cylinder body 1, which is mounted on a support seat 11. A cooling ring 2 is provided on the outer surface of the grinding cylinder body 1, and a plurality of cooling auxiliary structures 3 are provided on the cooling ring 2 in a circular array. The cooling auxiliary structure 3 comprises a driving motor 31, a rotating shaft 32, a plurality of guide blade groups 33 and a reflux assembly 34. The rotating shaft 32 is rotatably connected in the cooling ring 2, and the plurality of guide blade groups 33 and the reflux assembly 34 are all arranged on the rotating shaft 32, and the reflux assembly 34 is located below the guide blade group 33. The utility model adopts a cooling ring 2 provided on the outer surface of the grinding cylinder body 1 to facilitate cooling and heat removal during high-speed grinding, which can ensure that the grinding tool is not easily deformed and the paint sand mill can operate for a long time without stopping, thereby reducing the equipment maintenance cost and improving the work efficiency. The cooling auxiliary structure 3 built into the cooling ring 2 can disturb the coolant inside it, maintain the flow state of the coolant and improve its cooling efficiency.

[0027] In this embodiment, refer to Figure 1 and Figure 3The guide blade group 33 includes four guide blades 331 distributed in a circular array on the rotating shaft 32; the guide blade 331 has a rectangular structure, which can achieve a large-area disturbance of the coolant in the cooling ring 2 and increase its cooling area; multiple groups of guide blade groups 33 stir the coolant together, so that the coolant continues to flow in a circular shape along the cooling ring 2, thereby improving the cooling efficiency.

[0028] Specifically, the reflux component 34 includes a cylindrical seat 341 and a plurality of film pulps 342 obliquely arranged on the cylindrical seat 341, and the cylindrical seat 341 is arranged on the rotating shaft 32; the arrangement of the reflux component 34 can generate an upward driving force for the coolant at the bottom of the cooling ring 2, so that the coolant can circulate up and down, and its annular circulation can efficiently complete the all-round cooling of the grinding cylinder body 1.

[0029] For details, see Figure 3 and Figure 4 The film slurry 342 includes an inclined portion 3421 and a horizontal portion 3422. The inclined portion 3421 is inclined on the cylindrical seat 341, and a horizontal portion 3422 is provided at its end. When the driving motor 31 rotates, the film slurry 342 is driven to rotate, and the coolant will generate an upward driving force under the action of the film slurry 342, causing the coolant to float upward, and at the same time sink under the action of its gravity. Finally, the whole is in an up and down circulation state, thereby improving the cooling effect of the coolant.

[0030] In this embodiment, refer to Figure 1 The utility model also includes a water tank 4, and the upper and lower ends of the cooling ring 2 are respectively provided with a water inlet 21 and a water outlet 22.

Both the conduit 100 and the conduit 200 are provided with a valve 300. The setting of the water tank 4 plays a role in recycling the coolant. When it is used specifically, the coolant in the water tank 4 is introduced into the cooling ring 2 through the water inlet 21 until the coolant in the cooling ring 2 is almost full, so as to facilitate the disturbance of the coolant when the subsequent cooling auxiliary structure works.

[0031] In addition, the utility model also includes a cooling air ring 400, which is arranged on the outer surface of the cooling ring 2, and is provided with an air inlet 410 and an air outlet 420; the air inlet 410 and the air outlet 420 can be connected to an external cold zone source and a recovery source respectively; the setting of the cooling air ring 400 can first cool the coolant, keep the coolant in a low temperature state, and improve the cooling and heat removal effect of the coolant on the grinding cylinder body 1.

[0032] The working principle of this utility model:

[0033] The utility model provides a cooling device for a paint sand mill. When the paint sand mill is in use, during high-speed grinding, the coolant in the water storage tank 4 is introduced into the cooling ring 2 through the water inlet 21 until the coolant in the cooling ring 2 is almost full. When the driving motor 31 rotates, it drives the guide blade group 33 and the bottom film slurry 342 to rotate, so as to keep the coolant in a continuous annular flow and an up and down circulation state. The flow state of the coolant can be maintained to improve the cooling efficiency of the grinding cylinder body 1, ensure that the grinding tool is not easily deformed and the paint sand mill can operate for a long time without stopping, thereby reducing the equipment maintenance cost and improving the work efficiency.
