Description

Technical Field

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

[0002] When grinding alumina powder, pure calcium aluminate cement, spinel, and other refractory materials using a ball mill, the mill temperature rises due to prolonged continuous grinding. If not cooled promptly, overheating of the steel balls or liners can reduce their hardness and impact force, leading to decreased grinding efficiency and increased energy consumption. Current technology typically uses spray cooling on the ball mill surface; however, directly spraying water onto the mill surface results in significant water loss onto the ground, wasting water resources and polluting the working environment. Therefore, there is an urgent need for a mill spray cooling device that can cool the ball mill while minimizing water waste and preventing environmental pollution. Summary of the Invention

[0003] The purpose of this invention is to provide a mill spray cooling device that can both spray and cool the ball mill and recycle the spray water, reducing water waste and avoiding pollution of the working environment.

[0004] The present invention adopts the following technical solution:

[0005] A mill spray cooling device includes a water storage tank. One side of the water storage tank extends upward to above the mill, forming an arc-shaped baffle. A diversion pipe is installed inside the baffle, and an atomizing nozzle penetrating the bottom of the baffle is installed at the bottom of the diversion pipe. A water pump is conductively connected to the water storage tank, and the water pump is conductively connected to the diversion pipe through a water delivery pipe. A protective side plate is installed on the side of the water storage tank opposite to the baffle. In the initial state, the protective side plate is tightly abutting against the top of the baffle. The protective side plate is hinged to the water storage tank.

[0006] Preferably, the water storage tank has a hinge groove on its side wall, and one side of the protective side plate is hinged to the hinge groove via a hinge shaft; the other side of the protective side plate has a positioning groove, and the water storage tank is elastically provided with a positioning pin, one end of which is movably inserted through the side wall of the hinge groove.

[0007] Preferably, the end of the positioning pin that connects to the positioning groove has a cross-shaped or square structure.

[0008] Preferably, the water storage tank has two guide plates symmetrically arranged inclined towards the center, and a filter groove is provided between the two guide plates.

[0009] Preferably, a cleaning plate is slidably disposed inside the filter tank, and a cleaning port communicating with the filter tank is provided on one side of the water storage tank.

[0010] Preferably, both ends of the water storage tank are rotatably equipped with grooved wheels, one of which is driven by a motor; an annular steel wire rope is sleeved between the two grooved wheels, and a through hole is opened on the side wall of the water storage tank for the steel wire rope to pass through; the cleaning plate is arranged on the steel wire rope.

[0011] Preferably, the cleaning plate is provided with cleaning bristles on its periphery.

[0012] Preferably, the baffle has an internal hollow structure with a detachable cover plate, and both the diversion pipe and the water supply pipe are arranged inside the hollow structure of the baffle.

[0013] Compared with the prior art, the beneficial effects of this utility model are: This utility model uses an atomizing nozzle to uniformly spray cooling water in the form of a fine mist onto the surface of a high-temperature mill, which greatly increases the contact area between water and the mill surface, significantly improves the evaporation heat absorption efficiency, achieves rapid and uniform cooling of the mill, effectively prevents the mill from overheating and causing a decrease in the hardness of the steel balls / liners and a weakening of the impact force, maintains stable grinding efficiency, and avoids additional energy consumption caused by a decrease in efficiency.

[0014] The arc-shaped baffle installed above the mill not only supports the distribution pipe but also effectively catches and blocks any unevaporated water mist and droplets that may splash or flow during the spraying process. The integrated design of the baffle and water tank allows the blocked water to flow naturally downwards along the inner wall of the baffle and directly back into the water tank below, forming a closed-loop cooling water circulation system. This saves water resources and avoids pollution to the working environment. Attached Figure Description

[0018] The present invention will now be described clearly and completely with reference to the accompanying drawings and embodiments:

[0019] like Figures 1 to 3As shown, the mill spray cooling device of this utility model includes a water storage tank 1, which is open at the top. One side of the water storage tank 1 extends upward to the top of the mill to form an arc-shaped baffle 2. A diversion pipe 3 is provided inside the baffle 2, and an atomizing nozzle 4 penetrating the bottom of the baffle 2 is provided at the bottom of the diversion pipe 3. Preferably, the baffle 2 has an internal hollow structure and a cover plate 5 is detachably provided on it by bolts. The diversion pipe 3 and the water supply pipe 7 are both arranged inside the hollow structure of the baffle 2. The hollow structure of the baffle 2 can provide a space for the diversion pipe 3 and the water supply pipe 7. The cover plate 5 facilitates the subsequent disassembly and replacement and maintenance of the diversion pipe 3 and the water supply pipe 7. A water pump 6 is conductively connected to the water storage tank 1, and the water pump 6 is conductively connected to the diversion pipe 3 through the water supply pipe 7. This invention uses an atomizing nozzle 4 to uniformly spray cooling water in a fine mist onto the surface of a high-temperature mill, greatly increasing the contact area between the water and the mill surface, significantly improving evaporation and heat absorption efficiency, and achieving rapid and uniform cooling of the mill. This effectively prevents the mill from overheating, which could lead to a decrease in the hardness of the steel balls / liners and a reduction in impact force, maintaining stable grinding efficiency and avoiding additional energy consumption due to efficiency reduction. The integrated design of the baffle 2 and the water storage tank 1 allows the blocked water flow to naturally flow downwards along the inner wall of the baffle 2 and directly return to the water storage tank 1 below, forming a closed-loop cooling water circulation system. This saves water resources and avoids pollution to the working environment.

[0020] Furthermore, a protective side plate 8 is provided on the side of the water storage tank 1 opposite to the baffle 2. In the initial state, the protective side plate 8 is in close contact with the top of the baffle 2. The protective side plate 8 can shield the side of the mill opposite to the baffle 2, preventing water dripping onto the mill during spray cooling from being thrown out from the opposite side of the baffle 2 as the mill rotates, thus preventing some water loss and environmental pollution. Preferably, the side wall of the water tank 1 is provided with a hinge groove, and one side of the protective side plate 8 is hinged in the hinge groove through a hinge shaft; the other side of the protective side plate 8 is provided with a positioning groove, and a positioning pin 10 is elastically provided on the water tank 1 by a spring 9. One end of the positioning pin 10 is movably inserted through the side wall of the hinge groove, and the positioning pin 10 can be positioned in the positioning groove. This arrangement facilitates the adjustment of the position of the protective side plate 8, thereby making it easy to remove the water tank 1 from the bottom of the mill. When it is necessary to remove the water tank 1, the water tank 1 can be adjusted to a horizontal state. The end of the positioning pin 10 connected to the positioning groove is preferably a cross-shaped or square structure. Since the protective side plate 8 usually only needs two states, a vertical state or a horizontal state after a 90-degree rotation, setting the positioning groove and positioning pin 10 to a cross shape or a positive direction can meet the actual needs. In addition, a guide ramp 11 extending into the water storage tank 1 is provided on the side of the protective side plate 8 near the water storage tank 1. In the initial state, the guide ramp 11 extends into the water storage tank 1 so that the water flow trapped on the protective side plate 8 enters the water storage tank 1 along the guide ramp 11.

[0021] Furthermore, two guide plates 12 are symmetrically arranged inside the water storage tank 1, inclined towards the center, with a filter tank 13 located between the two guide plates 12. The inclined arrangement of the guide plates 12 helps the water flow blocked by the side plate 8 and the baffle 2 to enter the filter tank 13 along the guide plates 12, and then flow back to the water storage tank 1 below through the filter tank 13. The filter tank 13 can filter out dirt and prevent it from being recycled and clogging the atomizing nozzle 4. Since the working characteristics of the ball mill cause a lot of dust and dirt to adhere to its surface, filtration through the filter tank 13 can reduce the probability of equipment damage. A cleaning plate 14 is slidably installed inside the filter tank 13. A cleaning port 15 communicating with the filter tank 13 is provided on one side of the water storage tank 1. A sludge collection bag can be tied to the cleaning port 15. By periodically controlling the movement of the cleaning plate 14 inside the filter tank 13, the dirt in the filter tank 13 can be pushed into the sludge collection bag for discharge. A water inlet 16 is provided on the water storage tank 1 below the guide plate 12. A valve is provided at the water inlet 16 to facilitate the replenishment of water into the water storage tank 1.

[0022] Specifically, both ends of the water storage tank 1 are equipped with rotatable grooved wheels 17, one of which is driven by a motor. A ring-shaped steel wire rope 18 is fitted between the two grooved wheels 17, and a through hole 19 is provided on the side wall of the water storage tank 1 for the steel wire rope 18 to pass through. A cleaning plate 14 is mounted on the steel wire rope 18. As the motor drives the grooved wheels 17 to rotate, it moves the steel wire rope 18, thereby moving the cleaning plate 14 along the length of the filter tank 13 to remove the filtered dirt. In addition, cleaning bristles are provided around the cleaning plate 14 to improve the cleaning effect.

[0023] In use, first adjust the protective side plate 8 to a horizontal position, place the water storage tank 1 at the bottom of the mill, and then adjust the protective side plate 8 to a vertical position so that it abuts against the top side of the baffle 2; turn on the water pump 6 and use the atomizing nozzle 4 to spray the surface of the mill to cool it down. The water remaining on the surface of the mill will fall onto the guide plate 12 below, and after being filtered by the filter tank 13, it will enter the water storage tank 1 for recycling, which saves water and avoids pollution to the environment.

[0024] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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 this utility model should be included within the protection scope of this utility model.
