Description

Technical Field

[0001] This utility model relates to the field of ball mill technology, and in particular to a ball mill cylinder cooling and heat dissipation device. Background Technology

[0002] Ball mills are key equipment for further pulverizing materials after they have been crushed. This type of grinding mill is equipped with a certain number of steel balls as grinding media inside its cylinder. When the ball mill pulverizes the material, the impact and friction between the material and the grinding media inside the ball mill cylinder generates a large amount of heat.

[0003] A search revealed a Chinese patent (application number "201320779289.2") disclosing a "ball mill water cooling device." This device includes a cylinder and two bearing seats, with the cylinder positioned between the two bearing seats. A water collection pool is located below the cylinder, and a water spray pipe with several spray holes is located above the cylinder. The water spray pipe draws water from the water collection pool through an inlet pipe and discharges water into the water collection pool through an outlet pipe. However, during use, this water cooling device does not cool the water in the water collection pool. As the water temperature in the pool rises, the cooling effect of the ball mill cylinder deteriorates, resulting in low practicality. Utility Model Content

[0004] This utility model provides a ball mill cylinder cooling and heat dissipation device, which solves the problem proposed in the prior art that the water cooling device does not cool the water in the water collection tank when cooling the ball mill cylinder, resulting in a decrease in the cooling effect of the ball mill cylinder and low practicality after the water temperature in the water collection tank rises.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A ball mill cylinder cooling and heat dissipation device includes a waterproof cover disposed outside the ball mill cylinder. The waterproof cover includes an outer shell and two mounting rings respectively rotatably mounted on the outer wall of the outer shell. A heat exchange assembly is disposed inside the outer shell. The heat exchange assembly includes several mounting rings fixed on the outer wall of the ball mill cylinder, several heat exchange rings respectively fixed on the outer wall of the several mounting rings, and several partition plates. A water storage tank is disposed on one side of the waterproof cover. The water storage tank includes a box body with air inlets on both upper outer walls and a negative pressure fan. A cooling assembly is disposed inside the box body. The cooling assembly includes several horizontally arranged heat-conducting plates and several vertically arranged heat dissipation plates. A water pump is disposed between the waterproof cover and the box body.

[0006] Preferably, the two mounting rings are welded to the outer walls of the two sides of the housing, a water inlet pipe is fixed on the inner wall of the top of the housing, and a drain pipe is fixed on the inner wall of the bottom of the housing.

[0007] Preferably, several mounting rings are connected to the outer wall of the ball mill cylinder via thermally conductive gel, and mounting holes are opened on the outer walls of several heat exchange rings. Several partition plates are respectively inserted through and fixed in the mounting holes, and several partition plates are respectively welded to the outer walls of several mounting rings.

[0008] With the above scheme, cold water is delivered to the cooling space formed by the outer shell and the ball mill cylinder through the water inlet pipe. The cold water fills more than 50% of the cooling space. As the ball mill operates, the ball mill cylinder drives the mounting ring, heat exchange ring and partition plate to rotate. The multiple spaces formed by the mounting ring, heat exchange ring and partition plate temporarily store the cold water, so that the cold water can fully exchange heat with the ball mill cylinder, mounting ring, heat exchange ring and partition plate.

[0009] Preferably, a box cover is bolted to the top outer wall of the box body, and an air outlet is opened on the middle outer wall of the box cover. The negative pressure fan is bolted to the top outer wall of the box cover.

[0010] Preferably, each of the heat-conducting plates has a number of slots on its top outer wall, and the heat dissipation plates are fixed on both sides to the inner wall of the middle part of the box, and the heat dissipation plates are welded into the slots respectively.

[0011] Preferably, the water pump inlet is connected to the outer wall of one end of the drain pipe via a flange, and a conveying pipe is connected to the outer wall of the water pump outlet via a flange, with one end of the conveying pipe penetrating and fixed to the upper inner wall of one side of the housing.

[0012] With the above scheme, when the water temperature in the cooling space rises to a certain value, the water pump delivers the hot water in the cooling space to the box. The hot water first impacts the heat conduction plate and heat exchange plate, which perform initial cooling of the hot water. Then, the hot water exchanges heat with the lower part of the heat conduction plate in the box. At the same time, the negative pressure fan operates to transfer the heat on the heat conduction plate and heat exchange plate to the external environment, achieving continuous cooling of the hot water. Then, the cold water in the box is delivered back to the cooling space by the circulation pump.

[0013] The beneficial effects of this utility model are as follows: When the water temperature in the cooling space rises to a certain value, the water pump delivers the hot water from the cooling space into the chamber. The hot water first impacts the heat-conducting plate and heat exchange plate, which perform initial cooling on the hot water. Subsequently, the hot water exchanges heat with the lower part of the heat-conducting plate inside the chamber. At the same time, the negative pressure fan operates to transfer the heat on the heat-conducting plate and heat exchange plate to the external environment, achieving continuous cooling of the hot water. Then, the cold water in the chamber is delivered back to the cooling space through the circulation pump. This continuous cooling of the high-temperature cooling water prevents the ball mill cylinder from becoming less effective due to high water temperature, thus improving its practicality.

The 101 is equipped with a heat exchange assembly 2, which includes several mounting rings 201 fixed on the outer wall of the ball mill cylinder, several heat exchange rings 202 respectively fixed on the outer wall of the mounting rings 201, and several partition plates 203.

[0023] Example 2, refer to Figure 5-6 A ball mill cylinder cooling and heat dissipation device further includes a water storage tank 3. The water storage tank 3 includes a box body 301 with air inlets on both upper outer walls and a negative pressure fan 303. A box cover 302 is bolted to the top outer wall of the box body 301. An air outlet is opened in the middle outer wall of the box cover 302. The negative pressure fan 303 is bolted to the top outer wall of the box cover 302. A cooling component 4 is provided inside the box body 301. The cooling component 4 includes several horizontally arranged heat-conducting plates 401 and several vertically arranged heat dissipation plates 402. Several slots are opened on the top outer wall of the heat-conducting plates 401. Each heat sink 402 is fixed on both sides of the inner wall of the middle part of the box 301. Several heat sinks 402 are welded into several slots. Both the heat conduction plate 401 and the heat sink 402 are made of brass.

When the water temperature rises to a certain value, the water pump 5 delivers the hot water in the cooling space to the box 301. The hot water first impacts the heat conduction plate 401 and the heat exchange plate 402, which perform initial cooling on the hot water. Then, the hot water exchanges heat with the lower part of the heat conduction plate 401 in the box 301. At the same time, the negative pressure fan 303 operates to transfer the heat on the heat conduction plate 401 and the heat dissipation plate 402 to the external environment, achieving continuous cooling of the hot water. Then, the cold water in the box 301 is delivered back to the cooling space by the circulation pump.
