Abstract

This utility model discloses a ball mill for mineral crushing, including a base plate and a grinding jar. A first vertical plate and a second vertical plate are fixedly installed on the top left and right sides of the base plate, respectively. A discharge pipe and a feed pipe, rotatably connected to the first and second vertical plates, are respectively connected to the left and right sides of the grinding jar. An air intake assembly is connected to the right side of the feed pipe for injecting air into the feed pipe. A filter screen is fixedly installed inside the feed pipe. This utility model, by setting up an air intake assembly, a filter screen, and a heat exchange and dehumidification assembly, allows the air intake assembly to inject air into the feed pipe, and the heat exchange and dehumidification assembly to cool the air. Water vapor adheres to the heat exchange plates, reducing the moisture content of the air. The relatively dry air passes through the filter screen to remove any lint that may be present, and the clean, cold air enters the grinding jar. Thus, the temperature inside the grinding jar is lowered without allowing a large amount of water vapor to enter.

Description

Technical Field

[0001] This utility model relates to the field of ball mills, and in particular to a ball mill for mineral crushing. Background Technology

[0002] A ball mill is an industrial device that uses grinding media (such as steel balls, ceramic balls, etc.) to crush, mix, or grind materials. It is widely used in mining, building materials, chemical, and metallurgical industries. Its core principle is that the rotation of the cylinder drives the grinding media to move, and the materials are refined through impact, friction, and shearing forces.

[0003] When a ball mill is working, the heat generated by the high-speed collision of the internal material and abrasive accumulates, and the internal temperature rises. The grinding material may deteriorate at high temperatures. When cold air is directly input, the moisture in the air will condense into mist and come into contact with the material, causing the material to clump. Therefore, a ball mill for mineral crushing is proposed. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a ball mill for crushing minerals, which can input cold air with less moisture into the ball mill to cool down the material and prevent it from agglomerating.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] This utility model discloses a ball mill for mineral crushing, comprising a base plate and a grinding jar. A first vertical plate and a second vertical plate are fixedly installed on the top left and right sides of the base plate, respectively. A discharge pipe and a feed pipe, which are rotatably connected to the first vertical plate and the second vertical plate, are respectively connected to the left and right sides of the grinding jar. An air inlet assembly is connected to the right side of the feed pipe for injecting air into the feed pipe. A filter screen is fixedly installed inside the feed pipe. A heat exchange and dehumidification assembly is embedded at the bottom of the feed pipe and to the right of the filter screen for cooling the air in the feed pipe and absorbing moisture from the air.

[0007] As a preferred embodiment of this utility model, a force-bearing gear is fixedly installed on the outside of the grinding jar, a drive motor is fixedly installed on the top of the base plate, and a driving gear that meshes with the force-bearing gear is fixedly installed at the output end of the drive motor.

[0008] As a preferred embodiment of this utility model, the air intake assembly includes an air pump fixedly installed on the top of the base plate, and the air outlet of the air pump is connected to a conveying pipe whose other end is connected to the feed pipe.

[0009] As a preferred embodiment of this utility model, the top of the feed pipe is connected to a feeding pipe located on the left side of the filter screen, and the external thread of the feeding pipe is connected to a sealing cap.

[0010] As a preferred embodiment of this utility model, a water trough is provided on the inner bottom wall of the feed pipe, and a drain pipe that penetrates into the water trough is connected to the bottom of the feed pipe.

[0011] As a preferred embodiment of the present invention, the heat exchange and dehumidification assembly includes a semiconductor refrigeration chip embedded at the bottom of the feed pipe. The cooling end of the semiconductor refrigeration chip extends into the water tank, and a plurality of heat exchange plates are fixedly arranged on its cooling end. The heat dissipation end of the semiconductor refrigeration chip is located below the feed pipe, and a plurality of heat dissipation fins are fixedly arranged on its heat dissipation end.

[0012] As a preferred embodiment of this utility model, a positioning rod is fixedly provided at the bottom of the feed pipe, and a cooling fan located directly below the heat dissipation fins is fixedly provided on the positioning rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This invention incorporates an air intake assembly, a filter screen, and a heat exchange and dehumidification assembly. The air intake assembly injects air into the feed pipe, while the heat exchange and dehumidification assembly cools the air, causing water vapor to adhere to the heat exchange plates and reducing the moisture content in the air. The relatively dry air passes through the filter screen to remove any lint that may be present, allowing the clean, cool air to enter the grinding jar. In this way, the temperature inside the grinding jar is reduced without allowing a large amount of water vapor to enter. Attached Figure Description

[0025] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0026] In the attached diagram, all identical reference numerals refer to the same components.

[0027] Example 1

[0028] like Figure 1-3 As shown, this utility model provides a base plate 1 placed horizontally, with a first upright plate 2 and a second upright plate 3 fixedly installed on the left and right sides of its top, respectively. The grinding jar 4 is rotatably connected to the first upright plate 2 and the second upright plate 3 through the discharge pipe 5 and the feed pipe 6, respectively, to ensure that the grinding jar 4 can rotate freely. A force-bearing gear 13 is fixedly installed on the outside of the grinding jar 4, and a drive motor 14 is installed on the base plate 1, so that the drive gear 15 at its output end meshes with the force-bearing gear 13 to drive the grinding jar 4 to rotate.

[0029] In this embodiment, an air pump 11 is installed on the base plate 1, and its air outlet is connected to the right side of the feed pipe 6 through the delivery pipe 12 to form an air intake assembly; a filter screen 7 is fixedly installed inside the feed pipe 6 to filter impurities in the air.

[0030] In addition, a feeding pipe 61 is connected to the top of the feed pipe 6 and the left side of the filter screen 7, and a sealing cap 62 is threaded to its outside to facilitate feeding and sealing.

[0031] Furthermore, a water trough 63 is provided on the bottom wall of the feed pipe 6 and connected to a drain pipe 64 for draining condensate.

[0032] In this embodiment, a heat exchange and dehumidification assembly 8 is embedded at the bottom of the feed pipe 6 and the right side of the filter screen 7. A semiconductor cooling chip 81 extends into the water tank 63, and multiple heat exchange chips 82 are fixedly installed at equal intervals from left to right. The heat dissipation end is located below the feed pipe 6, and multiple heat dissipation fins 83 are installed on the heat dissipation end. A cooling fan 10 is fixedly installed directly below the heat dissipation fins 83 by a positioning rod 9 to enhance the heat dissipation effect.

[0033] Specifically, when using the equipment, the air pump 11 pumps air into the feed pipe 6 through the delivery pipe 12. When the air flows through the heat exchange and dehumidification component 8, the semiconductor cooling chip 81 cools the air. Water vapor condenses on the heat exchange plate 82 and drips into the water tank 63, and is discharged through the drain pipe 64.

[0034] Dry, cold air is further purified by filter 7 before entering the grinding tank 4, which lowers the internal temperature and prevents materials from clumping.

[0035] The drive motor 14 drives the grinding jar 4 to rotate through gear transmission, thereby achieving efficient crushing of materials.

[0036] Tests showed that when the ball mill was working continuously, the maximum temperature inside the grinding jar 4 could be reduced by 50-65 degrees Celsius, the material hardly deteriorated, and there was little agglomeration of the material.

[0037] In summary, this utility model, by setting up an air intake component, a filter screen 7, and a heat exchange and dehumidification component 8, allows air to be injected into the feed pipe 6 by the air intake component, and the heat exchange and dehumidification component 8 to cool the air. Water vapor adheres to the heat exchange plates 82, reducing the moisture content in the air. The relatively dry air passes through the filter screen 7 to remove any lint that may be present, and the clean, cold air enters the grinding jar 4. In this way, the temperature inside the grinding jar 4 is reduced without allowing a large amount of water vapor to enter the grinding jar 4.

[0038] 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.
