Description

Technical Field

[0001] This utility model relates to the field of sand mills, and in particular to a cathodic electrophoretic paint raw material sand mill with a protective structure. Background Technology

[0002] A sand mill is a high-efficiency grinding equipment widely used in the preparation of fine materials. Its narrow grinding chamber and concentrated grinding energy, combined with a high-performance cooling system and automatic control system, enable continuous material processing and discharge, greatly improving production efficiency. The sand mill achieves its grinding effect by using grinding media that, under the high-speed rotation of the dispersing blades, impact, compress, and shear the material.

[0003] Existing sand mills grind raw materials by adding grinding balls inside. The ground material is then separated and conveyed through a filter screen. However, existing sand mills are cylindrical, making it inconvenient to remove the grinding balls or filter screen when they need to be replaced or cleaned, which is quite troublesome. Therefore, a cathodic electrophoretic paint raw material sand mill with a protective structure is needed. Utility Model Content

[0023] The drive separation mechanism includes a hydraulic telescopic cylinder 10 fixedly connected to the upper surface of the support frame 9. The output end of the hydraulic telescopic cylinder 10 is fixedly connected to a drive plate 23. A ring 20 is rotatably connected to the surface of the conveying pipe 14. An annular T-groove 21 is opened on the surface of the ring 20. A convex shaft 22 is fixedly connected to the surface of the drive plate 23. The convex shaft 22 is installed inside the annular T-groove 21.

[0024] With the above structure, the grinding cylinder 2 is set to store the raw materials to be ground. The support frame 9 is set to support the connecting pipe 15 and keep the hydraulic telescopic cylinder 10 stable. The sealing plate 8 is set to seal the material when it is pressed against the grinding cylinder 2. When the sealing plate 8 is separated from the grinding cylinder 2, the grinding balls 12 and the filter screen 18 located in the sealing plate 8 can be easily removed. The filter screen 18 blocks the raw materials and grinding balls 12 during transportation, thus separating them. The annular T-groove 21 provides clearance space for the installation of the convex shaft 22. The driving plate 23 drives the convex shaft 22 to move, which in turn drives the ring 20 and the conveying pipe 14 to move together.

[0025] Preferably, an isolation cylinder 24 is fixedly connected to the inner wall of the grinding cylinder 2, a feed cylinder 6 is fixedly connected to the inner wall of the isolation cylinder 24, and a water inlet pipe 5 and a water outlet pipe 7 are fixedly connected to the inner wall of the base 1.

[0026] By setting up inlet pipe 5 and outlet pipe 7, cooling water is input and output. By setting up isolation cylinder 24, the cooling water entering the isolation cylinder 24 side will not come into contact with the grinding object inside the grinding cylinder 2.

[0027] Preferably, a sealing strip 19 is fixedly connected to the side of the sealing plate 8 near the grinding cylinder 2, and an O-ring 25 is fixedly connected to the surface of the conveying pipe 14, with the surface of the O-ring 25 in contact with the inner wall of the connecting pipe 15.

[0028] By setting the sealing strip 19, the sealing plate 8 and the grinding cylinder 2 are sealed, and by setting the O-ring 25, liquid leakage is prevented.

[0029] Preferably, a valve 13 is fixedly connected to the surface of the conveying pipe 14, and a plurality of grinding balls 12 are placed on the inner wall of the isolation cylinder 24.

[0030] By setting valve 13, the flow of raw materials in conveying pipe 14 is controlled, and by setting multiple grinding balls 12, the materials are ground.

[0031] Preferably, a plurality of baffles 16 are fixedly connected to the surface of the isolation cylinder 24 and the inner wall of the grinding cylinder 2, and flow holes 17 are opened on the surface of the plurality of baffles 16.

[0032] By setting multiple baffles 16, the residence time of cooling water in the isolation cylinder 24 is increased, and by setting flow holes 17, the normal flow of cooling water is ensured.

[0033] Preferably, a fixed frame 3 is fixedly connected to one side of the grinding cylinder 2, and a motor 4 is fixedly connected to the inner wall of the fixed frame 3. The output end of the motor 4 passes through the inner wall of the isolation cylinder 24 and is fixedly connected to multiple stirring shafts 11.

[0034] By setting a motor 4, multiple stirring shafts 11 are driven to rotate. The stirring shafts 11 are used to stir the raw materials located in the sand mill 2, and the grinding balls 12 are used to perform grinding operations.

[0035] The working principle of this utility model is as follows: A cathodic electrophoretic paint raw material sand mill with a protective structure is used. After adding grinding raw material into the sand mill cylinder 2 through the feed cylinder 6, the feed cylinder 6 is closed. At this time, cooling water is injected into the isolation cylinder 24 through the water inlet pipe 5. The cooling water can be discharged through the water outlet pipe 7. Then, the motor 4 is started. The output end of the motor 4 drives multiple agitator shafts 11 to rotate. The rotation of the agitator shafts 11 agitates the raw material in the sand mill cylinder 2. At the same time, multiple grinding balls 12 are used to perform sand milling. The ground raw material is transported to the continuous [processing unit] through the conveying pipe 14. When multiple grinding balls 12 or the filter screen 18 on the sealing plate 8 need to be replaced, the hydraulic telescopic cylinder 10 is activated. Its output end drives the driving plate 23 to move. The driving plate 23 drives the ring 20 to be stressed through the convex shaft 22, so that the ring 20 drives the conveying pipe 14 and the sealing plate 8 to move towards the connecting pipe 15. At this time, the sealing plate 8 moves away from the sand mill 2. With the above structure, the sand mill 2 can be opened, and the grinding balls 12 inside the sand mill 2 can be replaced, or the filter screen 18 on the sealing plate 8 can be disassembled and replaced.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
