Description

Technical Field

[0001] This invention relates to the field of copper oxide grinding and pulverizing technology, specifically to a grinding and pulverizing device for preparing copper oxide powder. Background Technology

[0002] In the preparation process of copper oxide powder, grinding and pulverizing is a crucial step, directly affecting the particle size distribution, purity, and physicochemical properties of the final product, thus influencing its application performance in numerous fields such as electronics, ceramics, and catalysis. Currently, in existing technologies, grinding and pulverizing equipment for copper oxide powder preparation typically uses grinding rollers as the main grinding component. The high-speed rotation of the grinding rollers and the friction and extrusion forces generated between them and the material achieve fine pulverization. However, during the grinding process, the grinding rollers generate a large amount of heat due to friction and compression. If this heat cannot be dissipated in time, it can lead to overheating of the grinding rollers. Excessive temperature may cause changes in the physical or chemical properties of the copper oxide powder, affecting its quality and reducing the lifespan of the grinding equipment. Summary of the Invention

A piston rod that can slide on the water storage pipe is fixedly installed at the end of the piston disc away from the sliding rod.

[0015] Preferably, a connecting slide rod is installed in the middle of the movable frame, and a first spring is sleeved on the connecting slide rod. One end of the first spring is connected to the movable frame, and the other end is connected to the fixed bracket. A central cavity is provided inside the grinding roller, and the fixed bracket is fixedly installed in the central cavity.

[0016] The water spray structure includes a fixed cylinder that is fixedly installed on a fixed bracket. The fixed cylinder is located in the central cavity.

[0019] Preferably, the fixing structure includes a fixing block fixedly installed on the movable frame, and the fixing block is provided with a fixing groove;

[0020] The clamping structure includes a support sleeve fixedly installed at one end of the piston rod and a sliding plate slidably connected to the piston rod.

[0021] Preferably, the box is provided with two baffles, the box is connected to a feed inlet, and a cover is fixedly connected to the box.

[0022] Preferably, one end of the telescopic connecting pipe is connected to a first rotary joint, the first rotary joint is connected to a water inlet connecting pipe, and a cold water tank is connected to the water inlet connecting pipe, the cold water tank being fixedly installed on the upper end of the cover.

[0024] Compared with the prior art, the beneficial effects of the present invention are:

[0025] By incorporating a uniform heating mechanism, the connecting slide rod drives the moving piston to draw some of the coolant from the water-cooling chamber into the fixed cylinder. During the water intake process, the flow of water within the water-cooling chamber is accelerated, resulting in more uniform heating. Simultaneously, the second bevel gear drives the connecting rod and the stirring blade to rotate, stirring the coolant within the water-cooling chamber, thereby accelerating the flow of water and improving the heat exchange efficiency.

[0026] Through the cooperation of the liquid driving mechanism, the uniform heating mechanism, and the drive connection mechanism, when water is stored inside the water storage pipe, the liquid driving mechanism and the uniform heating mechanism are automatically separated. Under the action of the first spring, the drive connection slide and the sliding tooth plate are reset, thereby realizing the re-mixing of water in the water-cooling cavity, further improving the heat exchange efficiency of the cooling water, reducing the amount of cooling water used, and achieving energy saving and consumption reduction.

[0027] With a liquid-driving mechanism, when the piston disc moves to the right, a negative pressure is formed on the left side of the piston disc. Cold water in the telescopic connecting pipe enters the left side of the piston disc through the central pipe, realizing liquid storage inside the water storage pipe. When the piston disc moves to the left, the piston disc transports the water in the water storage pipe to the water cooling chamber through the water inlet pipe, realizing liquid supply. The cold water exchanges heat with the grinding roller inside the water cooling chamber to cool the grinding roller. Attached Figure Description

[0047] refer to Figure 6 as well as Figure 9 It is understood that a support plate 62 is fixedly connected inside the water storage pipe 61, and a piston disc 66 is slidably installed inside the water storage pipe 61.

The moving piston 78 is fixedly connected to one end of the connecting slide rod 72. The water cooling cavity 3 is connected to the fixed cylinder 76 through a liquid guide pipe 77.

[0049] refer to Figure 7 as well as Figure 8 The stirring structure includes a sliding toothed plate 80 fixedly mounted on a movable frame 71. The sliding toothed plate 80 is slidably disposed within the central cavity 18. A first gear 81 meshes with the sliding toothed plate 80. A rotating rod 82, one end of which extends into the water-cooling cavity 3, is mounted on the first gear 81. The rotating rod 82 is rotatably disposed between the rotating rod 82 and the grinding roller 2. A first bevel gear 83 is fixedly connected to one end of the rotating rod 82 located inside the water-cooling cavity 3. A second bevel gear 84 meshes with the first bevel gear 83. A connecting rod 85 is fixedly connected to the middle of the second bevel gear 84. The connecting rod 85 is rotatably disposed within the water-cooling cavity 3. An agitator blade 86 is fixedly mounted on the connecting rod 85.

[0050] refer to Figure 12 The fixed structure includes a fixed block 92 fixedly installed on the movable frame 71, and a fixed groove 93 is provided on the fixed block 92; the clamping structure includes a support sleeve 94 fixedly installed on one end of the piston rod 67, a sliding plate 97 slidably connected to the piston rod 67, a connecting plate 96 symmetrically hinged to the sliding plate 97, a sliding insert plate 95 hinged to the end of the connecting plate 96 away from the sliding plate 97, the sliding insert plate 95 slidably connected to the support sleeve 94, the sliding insert plate 95 can extend into the fixed groove 93, and a second spring 98 is provided between the sliding plate 97 and the support sleeve 94.

[0051] refer to Figures 1 to 4 It is understood that by setting the first rotary joint 5 and the second rotary joint 15, cooling can be achieved during the rotation of 2. Two baffles 12 are set inside the box body 1, and a feed inlet 13 is connected to the box body 1. A cover 16 is fixedly connected to the box body 1. One end of the telescopic connecting pipe 64 is connected to the first rotary joint 5, and a water inlet connecting pipe 10 is connected to the first rotary joint 5. A cold water tank 11 is connected to the water inlet connecting pipe 10 and is fixedly installed on the upper end of the cover 16. A water inlet pipe 4 is connected to the water cooling chamber 3. The end of the water inlet pipe 4 away from the water cooling chamber 3 is connected to the water storage pipe 61. A one-way water inlet valve is set on the water inlet pipe 4. A water guide pipe 17 is connected to the water cooling chamber 3, and a drain pipe 14 is connected to the water guide pipe 17. A second rotary joint 15 is set on the drain pipe 14 and is connected to an external drain pipe.

[0052] In practical use, when cooling of the grinding roller 2 is required, the piston disc 66 is moved within the water storage pipe 61 by the electric telescopic rod 65. The telescopic connecting pipe 64 and the water inlet connecting pipe 10 can rotate through the first rotary joint 5, allowing water from the cold water tank 11 to enter the telescopic connecting pipe 64 through the water inlet connecting pipe 10. (Reference) Figure 6 and Figure 9 Understanding, with Figure 6 From the perspective shown, when the piston disc 66 moves to the right, a negative pressure is formed on the left side of the piston disc 66. The cold water in the telescopic connecting pipe 64 enters the left side of the piston disc 66 through the middle connecting pipe 68, realizing the storage of liquid inside the water storage pipe 61. When the piston disc 66 moves to the left, the piston disc 66 transports the water in the water storage pipe 61 to the water cooling chamber 3 through the water inlet pipe 4, realizing the supply of liquid. The cold water exchanges heat with the grinding roller 2 inside the water cooling chamber 3 to cool down the grinding roller 2.

[0053] When the piston disc 66 moves to the left to supply liquid, it drives the piston rod 67 to move. The piston rod 67 drives the support sleeve 94 to move closer to the fixed block 92. The sliding toothed plate 80, initially positioned at the edge of its upper groove, cannot move to the left. When the sliding insert plate 95 abuts against the fixed block 92, the fixed block 92 is in a stable state. When the sliding insert plate 95 continues to move, under the action of the second spring 98, the sliding insert plate 95 is locked inside the fixed groove 93. When the piston disc 66 moves to the right to store liquid, the piston rod 67 moves to the right to supply liquid. The stopper 66 drives the support sleeve 94 to move, which in turn drives the fixed block 92 and the moving frame 71 to move. The moving frame 71 drives the first spring 75 to stretch, and the moving frame 71 drives the connecting slide rod 72 to move. The connecting slide rod 72 drives the moving piston 78 to move, which can draw part of the coolant in the water-cooling chamber 3 into the fixed cylinder 76. During the water absorption process, the flow of water in the water-cooling chamber 3 can be accelerated, and the heating is more uniform. At the same time, the moving frame 71 drives the sliding toothed plate 80 to slide in the groove on the grinding roller 2. The sliding toothed plate 80 drives the first gear 81. The first gear 81 rotates, driving the first bevel gear 83 to rotate via the rotating rod 82. The first bevel gear 83 drives the second bevel gear 84 to rotate, which in turn drives the connecting rod 85 and the stirring blade 86 to rotate, thus stirring the coolant in the water-cooled chamber 3 and accelerating the water flow. When the sliding plate 97 contacts the water storage pipe 61, the water storage pipe 61 restricts the movement of the sliding plate 97, compressing the second spring 98. The sliding plate 97 then drives the sliding insert plate 95 to move out of the fixed block 92 via the connecting plate 96, releasing the pressure on the fixed block. Under the elastic action of the first spring 75, the movable frame 71 is reset by the restriction of 92. During the reset process, the movable frame 71 drives the connecting slide rod 72 and the movable piston 78 to spray the coolant drawn from the fixed cylinder 76 into the water-cooled cavity 3. The sprayed water can accelerate the flow of water in the water-cooled cavity 3. During the reset process, the sliding toothed plate 80 can drive the stirring blade 86 to stir the water-cooled cavity 3 again, which further improves the utilization rate of cooling water, improves the heat exchange efficiency of cooling water, reduces the amount of cooling water used, and achieves energy saving and consumption reduction.

[0054] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
