Technical Field

[0001] This utility model relates to the field of ball mill technology, and in particular to a ball mill for producing molten silicon micro powder. Background Technology

[0002] Ball mills are key pieces of equipment used for further pulverizing materials after they have been crushed. This type of grinding mill uses a certain number of steel balls as grinding media inside its cylinder.

[0003] Currently, silicon micromaterials are typically fed continuously during the grinding process. However, since silicon micromaterials vary in size, continuous feeding can easily cause blockages and affect the subsequent feeding effect.

[0004] Meanwhile, the device uses a deceleration method to drive the tank to rotate and grind the silicon micromaterials. However, the continuous meshing and rotation of the drive part of the device can easily increase the friction of the meshing, which can cause the drive part of the device to jam after long-term use, affecting the grinding quality of the silicon micromaterials.

[0005] Therefore, we propose a ball mill for the production of molten silicon micro powder to solve the problems mentioned above. Utility Model Content

[0006] By utilizing the corresponding movement of the first and second movable plates, the discharge of silicon micromaterials can be throttled according to the vertical height of the first and second movable plates, preventing excessive silicon micromaterials from causing blockage. At the same time, the absorbent cotton and rubber plate can be used to apply lubricating oil to the meshing point of the first and second gears for lubrication, thereby reducing the friction when the first and second gears mesh, thus solving the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: including a grinding tank, a throttling mechanism, and a lubrication mechanism. The throttling mechanism includes a first movable plate and a second movable plate, which are movably connected by a shaft. The first movable plate and the second movable plate are used to throttle the discharge of molten silicon material to prevent excessive discharge of molten silicon material from causing blockage.

[0008] The lubrication mechanism includes absorbent cotton and a rubber plate. The rubber plate is connected to the rear surface of the absorbent cotton. The absorbent cotton and the rubber plate are used to lubricate and rub the power source of the device, so as to reduce the friction when the grinding jar rotates.

[0009] Preferably, the throttling mechanism further includes a slider, the rear surface of which is movably connected to the interior of the first movable plate and the second movable plate via a shaft, and the upper surfaces of the first movable plate and the second movable plate are fixedly connected with connecting rods, the outer surface of which is fitted with handles.

[0011] Preferably, bearing seats are movably connected to both sides of the grinding jar, a base is fixedly connected to the lower surface of the bearing seats, a feed pipe is fixedly connected to the side surface of a set of bearing seats, a first motor is fixedly connected to the side surface of the feed pipe, a feed roller is fixedly connected to the output end of the first motor, a material box is fixedly connected to the upper surface of the feed pipe, and the inside of the material box is slidably connected to the slider.

[0012] Preferably, the front and rear surfaces of the other set of bearing seats are fixedly connected to a connecting cylinder, and the front surface of the connecting cylinder communicates with the box body. The rear surface of the connecting cylinder is provided with a wiping mechanism, which includes a collection box. A diversion plate is fixedly connected to the side surface of the collection box, and a wiping cloth is provided on the front surface of the diversion plate.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] 1. In this utility model, after the silicon micromaterial is put into the material box, the operator can hold the handle and pull the first and second movable plates upward, so that one side of the first and second movable plates can swing upward with the slider as the center. According to the tilt angle of the first and second movable plates, the slider can be pulled to slide inside the material box, thereby adjusting the size of the opening in the material box. This allows the silicon micromaterial to be added to the grinding tank in small amounts multiple times during discharge, preventing the excessive amount of silicon micromaterial during grinding from causing blockage and affecting the subsequent addition of silicon micromaterial.

The throttling mechanism 16 includes a first movable plate 161 and a second movable plate 164. The first movable plate 161 and the second movable plate 164 are movably connected by a shaft. The first movable plate 161 and the second movable plate 164 are used to throttle the discharge of molten silicon material to prevent excessive discharge of molten silicon material from causing blockage.

[0025] The lubrication mechanism 9 includes an absorbent cotton 902 and a rubber plate 903. The rubber plate 903 is connected to the rear surface of the absorbent cotton 902. The absorbent cotton 902 and the rubber plate 903 are used to lubricate the power source of the device, so as to reduce the friction when the grinding jar 5 rotates.

[0026] The effect achieved by the entire embodiment 1 is as follows: when the material is put into the inside of the material box 4, the corresponding movement of the first movable plate 161 and the second movable plate 164 allows the silicon micro material to be discharged according to the vertical height of the first movable plate 161 and the second movable plate 164, preventing excessive silicon micro material from causing blockage. At the same time, the absorbent cotton 902 and the rubber plate 903 can be used to apply lubricating oil to the meshing part of the first gear 8 and the second gear 10 for lubrication, thereby reducing the friction when the first gear 8 and the second gear 10 mesh.

[0027] Example 2, as Figure 1 and Figure 4 As shown, the throttling mechanism 16 also includes a slider 165. The rear surface of the slider 165 is movably connected to the interior of the first movable plate 161 and the second movable plate 164 respectively via a shaft. The upper surfaces of the first movable plate 161 and the second movable plate 164 are fixedly connected to a connecting rod 163. The outer surface of the connecting rod 163 is fitted with a handle 162.

[0028] The effect achieved by the entire embodiment 2 is as follows: after the silicon micromaterial is put into the material box 4, the operator can hold the handle 162 and pull the first movable plate 161 and the second movable plate 164 upward, so that one side of the first movable plate 161 and the second movable plate 164 can swing upward with the slider 165 as the center. According to the tilt angle of the first movable plate 161 and the second movable plate 164, the slider 165 can be pulled to slide inside the material box 4, thereby adjusting the size of the opening in the material box 4, so that the silicon micromaterial can be added into the grinding tank 5 in small amounts and multiple times when discharging, preventing the silicon micromaterial from being added in too much quantity during grinding, causing blockage and affecting the subsequent addition of silicon micromaterial.

[0029] Example 3, as Figure 1 - Figure 3The lubrication mechanism 9 also includes a box body 901. A spring 904 is fixedly connected inside the box body 901. An elastic plate 905 is fixedly connected to the rear end face of the spring 904. An opening is provided inside the elastic plate 905. The elastic plate 905 is in contact with the rubber plate 903. The left side of the absorbent cotton 902 extends into the interior of the box body 901. A connecting cylinder 14 is fixedly connected to both the front and rear surfaces of another set of bearing seats 12. The front surface of the connecting cylinder 14 communicates with the box body 901. A wiping mechanism 13 is provided on the rear surface of the connecting cylinder 14. The wiping mechanism 13 includes a collection box 131. A diversion plate 132 is fixedly connected to the side surface of the collection box 131. A wiping cloth 133 is provided on the front surface of the diversion plate 132. An inclined plate 134 is fixedly connected inside the collection box 131.

[0030] The overall effect achieved in Embodiment 3 is as follows: External lubricating oil is poured into the interior of the box 901. Utilizing the meshing of the rubber plate 903 with the first gear 8, when the first gear 8 rotates, the rubber plate 903 can shake according to the rotation of the first gear 8. When the rubber plate 903 shakes, it can push the elastic plate 905, causing the elastic plate 905 to compress the spring 904. Through the pushing force of the elastic plate 905, the lubricating oil inside the box 901 forms waves that enter the space in front of the elastic plate 905 through the opening. The absorbent cotton 902 can absorb the lubricating oil. Due to the rear of the rubber plate 903... The surface is inclined so that the lubricating oil absorbed in the absorbent cotton 902 can flow onto the inclined part of the rubber plate 903 to lubricate the meshing part of the first gear and the second gear 10 and reduce friction. At the same time, by using the contact between the wiping cloth 133 and the first gear 8, excess lubricating oil on the surface of the first gear 8 can be wiped and absorbed. When there is too much lubricating oil absorbed in the wiping cloth 133, the wiping cloth 133 is affected by the pressure contact of the first gear 8, so that the lubricating oil absorbed in the wiping cloth 133 can enter the interior of the collection box through the guide plate 132. The inclined plate 134 allows the collected lubricating oil to enter the interior of the box body 901 through the connecting cylinder 14 for use.

[0031] Example 4, as Figure 1 , Figure 2 and Figure 4As shown, the upper surface of the grinding tank 5 is provided with a discharge port 6, and the upper surface of the discharge port 6 is connected to a cover plate 7 by bolts. The outer surface of the grinding tank 5 is fitted with a first gear 8, and the front surface of the first gear 8 is fitted with a rubber plate 903. The rear surface of the first gear 8 is attached to a wiping cloth 133. The upper surface of the base 1 is fixedly connected to a second motor 11, and the output end of the second motor 11 is fixedly connected to a second gear 10, which meshes with the first gear 8. Both sides of the grinding tank 5 are movably connected to bearing seats 12, and the lower surface of the bearing seats 12 is fixedly connected to the base 1. A feed pipe 3 is fixedly connected to the side surface of a set of bearing seats 12, and a first motor 2 is fixedly connected to the side surface of the feed pipe 3. The output end of the first motor 2 is fixedly connected to a feed roller 15, and the upper surface of the feed pipe 3 is fixedly connected to a material box 4, and the inside of the material box 4 is slidably connected to a slider 165.

[0032] The overall effect of embodiment 4 is as follows: silicon micromaterials are put into the material box 4, and the first motor 2 and the second motor 11 are connected to an external power source. Starting the first motor 2 can drive the feed roller 15 to rotate, so that the feed pipe 3 can convey the silicon micromaterials entering the feed pipe 3 to the inside of the grinding jar 5. After the material enters the grinding jar 5, the steel balls used for grinding the silicon micromaterials can be poured into the inside of the grinding jar 5 through the discharge port 6. Starting the second motor 11 can drive the second gear 10 to rotate. By using the meshing connection between the second gear 10 and the first gear 8, the second gear 10 can drive the first gear 8 to rotate. The grinding jar 5 can rotate due to the meshing effect of the first gear 8 and the second gear 10. When the grinding jar 5 is rotating, the steel balls and silicon micromaterials in the grinding jar 5 roll together, and the silicon micromaterials are hammered and ground by the rolling and falling of the steel balls.

[0033] The working principle of the entire device is as follows: Silicon micromaterials are fed into the material box 4. Holding handle 162, the first movable plate 161 and the second movable plate 164 are pulled upwards, causing one side of the first movable plate 161 and the second movable plate 164 to swing upwards with slider 165 as the center. Based on the tilt angle of the first movable plate 161 and the second movable plate 164, slider 165 can be pulled to slide inside the material box 4, thereby adjusting the opening size in the material box 4. This allows the silicon micromaterials to be added to the grinding jar 5 in small amounts multiple times during discharge. Starting the first motor 2 drives the feed roller 15 to rotate, causing the feed pipe... 3 can convey the silicon micromaterials entering the feed pipe 3 to the inside of the grinding tank 5. After the material enters the grinding tank 5, the steel balls used for grinding the silicon micromaterials can be poured into the inside of the grinding tank 5 through the discharge port 6. The second motor 11 can drive the second gear 10 to rotate. The second gear 10 can drive the first gear 8 to rotate by meshing with the first gear 8. The grinding tank 5 can rotate due to the meshing of the first gear 8 and the second gear 10. When the grinding tank 5 is rotating, the steel balls and silicon micromaterials inside the grinding tank 5 roll together, and the silicon micromaterials are hammered and ground by the rolling and falling of the steel balls.

[0034] When the first gear 8 rotates, the rubber plate 903 can shake according to the rotation of the first gear 8. When the rubber plate 903 shakes, it can push the elastic plate 905, so that the elastic plate 905 can squeeze the spring 904. Through the pushing of the elastic plate 905, the lubricating oil in the box 901 is affected by the thrust and can form waves that enter the space in front of the elastic plate 905 through the opening. The absorbent cotton 902 can absorb the lubricating oil. Due to the rear surface of the rubber plate 903 The rubber plate 903 is inclined so that the lubricating oil absorbed in the absorbent cotton 902 can flow to the inclined part of the rubber plate 903 to lubricate the meshing part of the first gear and the second gear 10. When the amount of lubricating oil absorbed in the wiping cloth 133 is too much, the wiping cloth 133 is affected by the squeezing contact of the first gear 8, so that the lubricating oil absorbed in the wiping cloth 133 can enter the interior of the collection box through the guide plate 132. The inclined plate 134 is used to allow the collected lubricating oil to enter the interior of the box body 901 through the connecting cylinder 14 for use.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
