DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0026] As Figures 1-5 shown, a technical solution provided by the present utility model:

[0027] A ball milling device for processing electro-heating ceramic powder materials includes a base 1, with frames 2 symmetrically arranged on both sides of the base 1. Between the tops of the two frames 2 is provided a ball mill shell 3. Driving mechanisms are arranged on the inner and outer sides of the two frames 2. The driving mechanism includes a motor 6, and the motor 6 is arranged on the outer side of the bottom end of the frame 2. At the upper and lower ends inside the frame 2 are respectively provided a driven pulley 7 and a driving pulley 8. The driven pulley 7 and the driving pulley 8 are movably connected by a transmission belt. The output shaft of the motor 6 is fixedly connected to the driving pulley 8. The driven pulley 7 at the upper end inside the right frame 2 is fixedly connected to the right side of the ball mill shell 3; a semi-circular filter screen one 4, and the semi-circular filter screen one 4 is movably installed at the upper middle part inside the ball mill shell 3. Below the inside of the ball mill shell 3 near the semi-circular filter screen one 4 is provided a semi-circular filter screen two 5; a ball milling mechanism is arranged in the middle of the ball mill shell 3. The ball milling mechanism includes a transmission shaft 9, and the transmission shaft 9 is movably installed at the middle part inside the ball mill shell 3. One end of the transmission shaft 9 is fixedly connected to the driven pulley 7 inside the left frame 2. A number of grinding rollers 10 are arranged side by side in the middle of the transmission shaft 9. The outer side of the grinding roller 10 is movably connected to the inner side of the semi-circular filter screen two 5. The outer diameter of the guide plate two 12 is smaller than the inner diameter of the guide plate one 11. At the middle parts of the top and bottom ends of the ball mill shell 3 are provided outer shells 17. Inside one side of each of the two outer shells 17 is movably installed an arc-shaped baffle 18. Outside the arc-shaped baffle 18 is provided a handle 19;

[0028] In this embodiment, during grinding, open the arc-shaped baffles 18 at the upper and lower ends of the ball mill shell 3, put the ceramic raw materials into it, and then use the arc-shaped baffles 18 to close the upper inlet. After the materials enter from the upper end, the large-volume particulate matters in the raw materials are filtered by the semi-circular filter screen one 4, and start the motor 6 on the left side. The motor 6 controls the rotation of the transmission shaft 9 through the cooperation of the driven pulley 7, the driving pulley 8 and the transmission belt. When the transmission shaft 9 rotates, it drives the grinding rollers 10 to grind and process the filtered ceramic raw materials. The ground materials pass through the semi-circular filter screen two 5 and are discharged from the lower outlet. After processing, start the motor 6 on the right side. The motor 6 drives the ball mill shell 3 to rotate 90°. At this time, the positions of the inlet and outlet are swapped. Since the guide plate one 11 and the guide plate two 12 face downward, the sundries intercepted on the semi-circular filter screen one 4 flow out from the channels on both sides of the guide plate one 11 and the guide plate two 12 and fall on the inner wall of the ball mill shell 3. Then, reverse the rotation of the ball mill shell 3 by the motor 6 on the right side. At this time, the positions of the inlet and outlet are swapped again, and the materials falling on the inner wall of the ball mill shell 3 slide down along the inner wall due to the action of gravity and are discharged from the opened outlet.

[0029] As Figure 2 and Figure 5As shown in the figure, a vibration mechanism is provided between the ball milling mechanism and the first semi-circular filter screen 4. The vibration mechanism includes a first material guiding plate 11, which is fixedly installed at the middle of the top end of the first semi-circular filter screen 4. On the upper inner surface of the ball mill housing 3, a second material guiding plate 12 is provided. On both sides of the second material guiding plate 12, springs 14 are fixedly installed through side plates 13, and the other ends of the springs 14 are arranged on the upper surface of the first semi-circular filter screen 4. On both sides of the transmission shaft 9, cams 15 are provided. At both inner ends of the first semi-circular filter screen 4, vibration blocks 16 are provided at positions opposite to the cams 15.

[0030] In this embodiment, during grinding, in addition to controlling the rotation of the grinding roller 10, the transmission shaft 9 also drives the cams 15 at both ends to rotate. When the cams 15 rotate, they impact the vibration blocks 16, and the vibration blocks 16 control the vibration of the first semi-circular filter screen 4. In this way, the raw materials falling above the first semi-circular filter screen 4 can be vibration-screened. After the first semi-circular filter screen 4 is reversed, the impurities remaining on the outer side surface of the first semi-circular filter screen 4 can also be shaken off.

[0031] Working principle: During grinding, open the arc-shaped baffles 18 at the upper and lower ends of the ball mill housing 3, put the ceramic raw materials into it, and then use the arc-shaped baffles 18 to close the upper inlet. After the materials enter from the upper end, the large-volume particulate matters in the raw materials are filtered through the first semi-circular filter screen 4, and start the motor 6 on the left side. The motor 6 controls the rotation of the transmission shaft 9 through the cooperation of the driven belt pulley 7, the driving belt pulley 8 and the transmission belt. When the transmission shaft 9 rotates, it drives the grinding roller 10 to grind and process the filtered ceramic raw materials. The ground materials pass through the second semi-circular filter screen 5 and are discharged from the lower outlet. After processing, start the motor 6 on the right side, and the motor 6 drives the ball mill housing 3 to rotate 90°. At this time, the positions of the inlet and outlet are swapped. Since the directions of the first material guiding plate 11 and the second material guiding plate 12 are downward, the sundries intercepted on the first semi-circular filter screen 4 flow out from the channels on both sides of the first material guiding plate 11 and the second material guiding plate 12 and fall on the inner wall of the ball mill housing 3. Then, reverse the ball mill housing 3 through the motor 6 on the right side. At this time, the positions of the inlet and outlet are swapped again, and the materials falling on the inner wall of the ball mill housing 3 slide down along the inner wall due to the action of gravity and are discharged from the opened outlet. During grinding, in addition to controlling the rotation of the grinding roller 10, the transmission shaft 9 also drives the cams 15 at both ends to rotate. When the cams 15 rotate, they impact the vibration blocks 16, and the vibration blocks 16 control the vibration of the first semi-circular filter screen 4. In this way, the raw materials falling above the first semi-circular filter screen 4 can be vibration-screened. After the first semi-circular filter screen 4 is reversed, the impurities remaining on the outer side surface of the first semi-circular filter screen 4 can also be shaken off.

[0032] The above has shown and described the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only preferred examples of the present utility model and are not used to limit the present utility model.
