Description

Technical Field

[0001] The utility model belongs to the technical field of dielectric energy storage ceramic materials, in particular to a raw material grinding device for high energy storage ceramic dielectric materials. Background Art

[0002] During the production of high energy storage ceramic dielectric materials, it is necessary to grind the raw materials to improve the physical properties. This allows for a uniform particle distribution during the ceramic preparation process, which helps improve the density and consistency of the ceramic. Therefore, it is necessary to grind the raw materials of high energy storage ceramic dielectrics.

[0003] Currently, grinding raw materials for high-energy-storage ceramic dielectrics primarily involves ball milling. During processing, the raw materials are placed in a ball mill, where they are processed to reduce particle size and improve uniformity. The raw materials are placed in the mill's grinding jar, along with a specific number and size of grinding balls (such as zirconia balls). Once the mill is started, the jar rotates at a constant speed around its horizontal axis, driving the grinding balls within it through complex motions, including projection, falling, rolling, and sliding against each other. During these motions, the grinding balls impact, squeeze, and rub against the raw material particles, gradually grinding the raw material into fine particles.

[0004] In the existing high-energy storage ceramic dielectric material raw material grinding, when the raw materials are placed in the ball milling equipment, some ethanol needs to be added to the raw materials to realize the role of dispersant. However, in the existing ball milling process, the raw materials and ethanol are not mixed sufficiently, resulting in the problem of agglomeration of the raw materials, which in turn affects the ball milling effect.

[0005] To this end, the utility model provides a high-energy storage ceramic dielectric material raw material grinding device. Utility Model Content

[0006] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0007] The technical solution adopted by the present invention to solve its technical problems is: the high-energy storage ceramic dielectric material raw material grinding device described in the present invention comprises a frame; a ball mill is rotatably connected to the top of the frame; a motor is fixedly connected to the side wall of the frame; a belt is installed between the output end of the motor and the frame; a bracket is fixedly connected to the side wall of the frame; a feed trough is fixedly connected to the top of the bracket; a discharge trough is fixedly connected to the side wall of the frame away from the bracket; the discharge trough port is aligned with the ball mill; a liquid adding pipe is fixedly connected to the middle of the feed trough; a plurality of liquid outlet holes are opened at the bottom of the liquid adding pipe; the liquid outlet holes are located inside the feed trough; by adding a liquid adding pipe inside the feed trough, ethanol is added to the raw materials that need to be ball milled for mixing, so that the raw materials can come into contact with ethanol during the blanking process, thereby achieving mixing of ethanol and raw materials. This arrangement reduces the problem of uneven ball milling caused by aggregation and agglomeration of raw materials.

[0008] Preferably, a plurality of springs are fixed to the top of the liquid adding tube; a protective cover is fixed to the top of the spring; by adding springs and a protective cover to the top of the liquid adding tube, direct contact between the raw materials and the middle of the liquid adding tube can be reduced, and damage to the liquid adding tube caused by impact of the raw materials after long-term use can be reduced. At the same time, the protective cover disperses the raw materials, which can further enhance the mixing of ethanol and the raw materials.

[0009] Preferably, an elastic cloth is fixed to the inner wall of the bottom of the feed trough; a vibrator is installed at the bottom of the feed trough; by arranging the elastic cloth and the vibrator in the middle of the feed trough, the raw materials inside the feed trough can fall more quickly and fully, and at the same time, the setting of the elastic cloth can maintain a certain amplitude of shaking when the vibrator is working, which can make the vibrator's conveying effect on the raw materials inside the feed trough more obvious, and reduce the waste problem caused by the accumulation of raw materials inside the feed trough.

[0010] Preferably, a material receiving bin is installed on the side wall of the frame; the material receiving bin is located at the bottom of the discharge trough; a plurality of partition plates are fixedly connected to the inner side wall of the material receiving bin; by adding a material receiving bin and a partition plate to the side wall of the frame, the material inside the ball mill can be discharged directly through the material receiving bin to receive the milled material, and at the same time, when the material falls into the material receiving bin, there will be a splashing problem. When the raw material splashes, it can be blocked by the partition plate in the middle of the material receiving bin and then fall back into the material receiving bin; this arrangement reduces the waste caused by splashing when the material is received in the material receiving bin.

[0011] Preferably, a plurality of blowing pipes are fixedly connected to the top of the material receiving bin; an air outlet is opened in the middle of the blowing pipe; the air outlet is arranged toward the inside of the material receiving bin; by arranging a blowing pipe on the top of the material receiving bin, the end of the blowing pipe can be connected to the air pump when the material receiving bin receives the material, and the air pump will send the gas into the inside of the blowing pipe and then spray it out from the air outlet. This arrangement can increase the falling of the material and reduce the residual material adhesion on the partition plate.

[0012] Preferably, the side wall of the receiving bin is fixedly connected to a guide rail; the middle part of the guide rail is slidably connected to a baffle; by providing a sliding baffle on the side wall of the receiving bin, when the receiving bin receives the material, the baffle can be pulled up and stand on the side wall of the receiving bin, which can further reduce the waste caused by material splashing and the problem of tilted material falling position caused by air flow near the ball mill can be reduced.

[0013] The beneficial effects of the utility model are as follows:

[0014] 1. The high-energy storage ceramic dielectric material raw material grinding device described in the utility model adds a liquid adding tube inside the feed trough to add ethanol to the raw materials that need to be ball-milled for mixing. This can achieve contact with ethanol during the raw material dropping process, thereby achieving mixing of ethanol and raw materials. This setting reduces the problem of uneven ball milling caused by the aggregation of raw materials.

[0015] 2. The high-energy storage ceramic dielectric material raw material grinding device described in the utility model is equipped with a blowing pipe on the top of the material receiving bin. When the material receiving bin receives the material, the end of the blowing pipe can be connected to the air pump. At this time, the air pump sends gas into the blowing pipe and then sprays it out from the air outlet. This setting can increase the falling of the material and reduce the material adhesion residue on the partition plate. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] like Figures 1 to 3 As shown, a high energy storage ceramic dielectric material raw material grinding device described in an embodiment of the present invention includes a frame 1; a ball mill 11 is rotatably connected to the top of the frame 1; a motor 12 is fixedly connected to the side wall of the frame 1; a belt 13 is installed between the output end of the motor 12 and the frame 1; a bracket 14 is fixedly connected to the side wall of the frame 1; a feed trough 15 is fixedly connected to the top of the bracket 14; a discharge trough 16 is fixedly connected to the side wall of the frame 1 away from the bracket 14; the port of the discharge trough 16 is aligned with the ball mill 11; a liquid adding pipe 17 is fixedly connected to the middle of the feed trough 15; a plurality of liquid outlet holes 18 are opened at the bottom of the liquid adding pipe 17; the liquid outlet holes 18 are located inside the feed trough 15; when in use, the raw materials to be ground are first added to the inside of the feed trough 15. During this process, the liquid adding pipe 17 needs to be connected to the ethanol supply pipeline. At this time, ethanol can be sprayed out through the liquid outlet 18 on the liquid adding pipe 17, and then can be mixed with the ethanol sprayed out of the liquid outlet 18 during the process of the raw material falling from the inside of the feed trough 15, so that the raw material is fully dispersed after entering the ball mill 11, and then the motor 12 can be turned on. At this time, the motor 12 can drive the ball mill 11 to rotate through the belt 13. At this time, the raw material of the high energy storage ceramic medium material contacts the grinding balls inside the ball mill 11 to realize ball milling of the raw material. After the ball milling is completed, it is discharged from the discharge trough 16 at the other end of the ball mill 11 to complete the ball milling process; by adding a liquid adding pipe 17 inside the feed trough 15 to add ethanol to the raw material that needs to be ball milled, it can be realized that the raw material is in contact with ethanol during the falling process, and the ethanol and raw material are mixed. This setting reduces the problem of uneven ball milling caused by the aggregation of raw materials.

[0025] like Figure 3 As shown, a plurality of springs 2 are fixed to the top of the liquid adding tube 17; a protective cover 21 is fixed to the top of the spring 2; by adding the spring 2 and the protective cover 21 to the top of the liquid adding tube 17, the raw materials can be in contact with the protective cover 21 during the process of adding the raw materials into the feed trough 15, and then fall from both sides of the protective cover 21, thereby reducing the direct contact between the raw materials and the middle of the liquid adding tube 17, and reducing the damage caused by the impact of the raw materials after long-term use of the liquid adding tube 17. At the same time, the protective cover 21 disperses the raw materials, which can further enhance the mixing of ethanol and the raw materials.

[0026] like Figure 2As shown, an elastic cloth 3 is fixed to the inner side wall of the bottom of the feed trough 15; a vibrator 31 is installed at the bottom of the feed trough 15; by arranging the elastic cloth 3 and the vibrator 31 in the middle of the feed trough 15, the vibrator 31 can be turned on during the process of adding raw materials into the feed trough 15. At this time, the vibrator 31 can drive the entire feed trough 15 to vibrate, so that the raw materials inside the feed trough 15 can fall more quickly and fully. At the same time, the setting of the elastic cloth 3 can maintain a certain amplitude of shaking when the vibrator 31 is working, so that the vibrator 31 can make the raw material conveying effect of the feed trough 15 more obvious, thereby reducing the waste problem caused by the accumulation of raw materials inside the feed trough 15.

[0027] like Figure 4 As shown, a receiving bin 4 is installed on the side wall of the frame 1; the receiving bin 4 is located at the bottom of the discharge trough 16; a plurality of partition plates 41 are fixedly connected to the inner side wall of the receiving bin 4; by adding a receiving bin 4 and a partition plate 41 to the side wall of the frame 1, the material after ball milling 11 can be directly received by the receiving bin 4 when the material is discharged, and at the same time, when the material falls into the receiving bin 4, there will be a splashing problem. When the raw material splashes, it can be blocked by the partition plate 41 in the middle of the receiving bin 4, and then fall back into the receiving bin 4; this arrangement reduces the waste caused by splashing when the receiving bin 4 receives the material.

[0028] like Figure 5 As shown, a plurality of blowing pipes 5 are fixedly connected to the top of the material receiving bin 4; an air outlet hole 51 is opened in the middle of the blowing pipe 5; the air outlet hole 51 is set toward the inside of the material receiving bin 4; by providing the blowing pipe 5 on the top of the material receiving bin 4, the end of the blowing pipe 5 can be connected to the air pump when the material receiving bin 4 receives the material, and the air pump will send the gas into the inside of the blowing pipe 5 and then spray it out from the air outlet 51. This setting can increase the falling of the material and reduce the material adhesion residue on the partition plate 41.

[0029] like Figure 4 As shown, the side wall of the receiving bin 4 is fixedly connected with a guide rail 6; the middle part of the guide rail 6 is slidably connected with a baffle 61; by providing a slidable baffle 61 on the side wall of the receiving bin 4, when the receiving bin 4 receives the material, the baffle 61 can be pulled up and stand on the side wall of the receiving bin 4, which can further reduce the waste caused by material splashing and the problem of the tilted falling position of the material caused by the air flow near the ball mill 11.

[0030] Working principle: When in use, first add the raw materials to be ground into the feed trough 15. During this process, the liquid adding pipe 17 needs to be connected to the ethanol supply pipe. At this time, ethanol can be sprayed out through the liquid outlet 18 on the liquid adding pipe 17. Then, when the raw materials fall from the feed trough 15, they can be mixed with the ethanol sprayed out of the liquid outlet 18, so that the raw materials are fully dispersed after entering the ball mill 11. Then the motor 12 can be turned on. At this time, the motor 12 can drive the ball mill 11 to rotate through the belt 13. At this time, the raw materials of high energy storage ceramic medium material are in contact with the grinding balls inside the ball mill 11 to realize ball milling of the raw materials. After the ball milling is completed, they are discharged from the discharge trough 16 at the other end of the ball mill 11 to complete the ball milling process. By adding a spring 2 and a protective cover 21 on the top of the liquid adding pipe 17, the raw materials can be in contact with the protective cover 21 when the raw materials are added to the feed trough 15, and then discharged from the protective cover. 21 falls on both sides, reducing the direct contact between the raw materials and the middle of the liquid adding pipe 17, by providing an elastic cloth 3 and a vibrator 31 in the middle of the feed trough 15, the vibrator 31 can be turned on during the process of adding raw materials into the feed trough 15, and the vibrator 31 can drive the feed trough 15 to vibrate as a whole, so as to realize the faster and more sufficient falling of the raw materials inside the feed trough 15, and by adding a receiving bin 4 and a partition plate 41 to the side wall of the frame 1, the material after ball milling 11 can be directly received by the receiving bin 4 when the material inside the ball mill 11 is discharged, and there will be a problem of splashing when the material falls into the receiving bin 4, and by providing a blowing pipe 5 on the top of the receiving bin 4, the end of the blowing pipe 5 can be connected to the air pump when the receiving bin 4 receives the material, and the air pump will send the gas into the blowing pipe 5 and then spray it out from the air outlet 51. This setting can increase the falling of the material and reduce the material adhesion residue on the partition plate 41. By providing a sliding baffle 61 on the side wall of the receiving bin 4, the baffle 61 can be pulled up and placed on the side wall of the receiving bin 4 when the receiving bin 4 receives the material. At this time, the waste caused by material splashing can be further reduced, and the problem of the tilted falling position of the material caused by the air flow near the ball mill 11 can be reduced.
