Description

Technical Field

[0001] This utility model relates to the field of silicon carbide production technology, and in particular to a production device that can improve the flowability of silicon carbide fine powder. Background Technology

[0002] Silicon carbide fine powder is an ultrafine powder material with silicon carbide as the main component. It has the characteristics of high hardness, high wear resistance, high thermal conductivity and good chemical stability, and is widely used in abrasives, refractory materials, semiconductors, ceramics, metallurgy and other fields.

[0003] In the existing technology for producing silicon carbide fine powder, hoppers are often used for feeding. Since the diameter of the hopper decreases sharply at the feeding port, the silicon carbide fine powder is prone to accumulating and forming bridges at the feeding port, which affects the falling of the silicon carbide fine powder. Utility Model Content

[0004] This invention addresses the shortcomings of existing technologies by proposing a production device that can improve the flowability of silicon carbide fine powder.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a production device for improving the flowability of silicon carbide fine powder, comprising a hopper, wherein the hopper is installed at the feed inlet of the silicon carbide fine powder processing equipment, and a stirring device is disposed inside the hopper, wherein the stirring device can stir the silicon carbide fine powder inside the hopper.

[0006] The effect achieved by the above components is as follows: when silicon carbide fine powder needs to be processed, the operator places the silicon carbide fine powder into the hopper, and the stirring device stirs the silicon carbide fine powder to prevent the silicon carbide fine powder from accumulating inside the hopper. The silicon carbide fine powder enters the processing equipment through the hopper.

[0007] Preferably, the stirring device includes a motor mounted on the arc surface of the hopper. The motor is fixedly connected to a gear via a reducer. A gear ring is rotatably connected to the arc surface of the hopper, wherein the gear ring and the gear mesh with each other. Two cleaning plates are disposed inside the hopper, wherein the cleaning plates are in contact with the inner wall of the hopper. One end of each cleaning plate is fixedly connected to the gear ring. The ends of the two cleaning plates that are close to each other are fixedly connected to the same connecting plate, wherein the connecting plate can connect the two cleaning plates. The two first stirring plates are fixedly connected to the top of the connecting plate, wherein the first stirring plates and the connecting plate are perpendicular to each other.

[0008] The effect achieved by the above components is as follows: When it is necessary to stir the silicon carbide fine powder in the hopper, the operator turns on the motor. The motor drives the gear to rotate through the reducer. The gear drives the toothed ring and the cleaning plate to rotate. The cleaning plate cleans the inner wall of the hopper to prevent the silicon carbide fine powder from sticking to the inner wall of the hopper. At this time, the first stirring plate rotates vertically inside the hopper under the drive of the connecting plate, which achieves the effect of loosening the silicon carbide fine powder in the hopper. The vertical rotation of the first stirring plate in the hopper by the stirring device achieves the effect of loosening the silicon carbide fine powder, avoiding the bridging phenomenon of silicon carbide fine powder in the hopper, which would affect the normal feeding of silicon carbide fine powder.

[0009] Preferably, a triangular plate is fixedly connected to the upper surface of the connecting plate, wherein the tip of the triangular plate is far away from the connecting plate.

[0010] The effect achieved by the above components is that the triangular plate guides the connecting plate, preventing silicon carbide powder from accumulating on the upper surface of the connecting plate.

[0011] Preferably, one end of the first stirring plate is fixedly connected to two mutually symmetrical extension members, and the cross-sections of the two extension members are "V" shaped.

[0012] The effect achieved by the above components is that by setting the extension element, the contact area between the first stirring plate and the silicon carbide fine powder is increased, thereby improving the stirring effect of the first stirring plate on the silicon carbide fine powder.

[0013] Preferably, limit rings are provided on both sides of the toothed ring, and two of the limit rings are fixedly connected to the hopper.

[0014] The effect achieved by the above-mentioned components is that by setting a limiting ring, the gear ring is limited, preventing it from shaking and thus avoiding misalignment between the gear ring and the gear.

[0015] Preferably, the hopper is equipped with an auxiliary device, which includes two symmetrical rotating rods. One end of the two rotating rods is rotatably connected to the inner wall of the hopper. One end of the rotating rod is fixedly connected to a support plate, wherein a connecting plate abuts against one side of the support plate. Two symmetrical second stirring plates are fixedly connected to one side of the support plate. A coil spring is sleeved on the arc surface of the rotating rod, wherein the two ends of the coil spring are fixedly connected to the support plate and the inner wall of the hopper, respectively.

[0016] The effect achieved by the above components is as follows: when the connecting plate rotates, the connecting plate abuts against the support plate, and the support plate rotates along with the rotating rod and the second stirring plate. The coil spring deforms, and when the connecting plate moves past the support plate, under the action of the coil spring's return force, the rotating rod, the support plate, and the second stirring plate rotate back to their original positions. As the connecting plate continues to rotate, the second stirring plate rotates laterally back and forth, achieving the effect of loosening the silicon carbide fine powder. The second stirring plate, set by the auxiliary device, rotates laterally and repeatedly inside the hopper, further stirring the silicon carbide fine powder in the hopper and improving the loosening effect of the silicon carbide fine powder.

[0017] Preferably, the arc surface of the rotating rod is fitted with a protective tube, one end of which is fixedly connected to the inner wall of the hopper, and the other end of which is rotatably connected to the support plate.

[0018] The effect achieved by the above-mentioned components is that the protective tube protects the coil spring and prevents fine silicon carbide powder from sticking to the coil spring.

[0019] In summary, the beneficial effects of this utility model are as follows:

[0020] When it is necessary to stir the silicon carbide fine powder in the hopper, the operator turns on the motor. The motor drives the gear to rotate through the reducer. The gear drives the toothed ring and the cleaning plate to rotate. The cleaning plate cleans the inner wall of the hopper to prevent the silicon carbide fine powder from sticking to the inner wall of the hopper. At this time, the first stirring plate rotates vertically inside the hopper under the drive of the connecting plate, which achieves the effect of loosening the silicon carbide fine powder in the hopper. The vertical rotation of the first stirring plate in the stirring device achieves the effect of loosening the silicon carbide fine powder and prevents the silicon carbide fine powder in the hopper from bridging, which would affect the normal feeding of silicon carbide fine powder.

A gear ring 23 is rotatably connected to the arc surface of the hopper 1, wherein the gear ring 23 and the gear 22 mesh with each other. Two cleaning plates 24 are disposed inside the hopper 1, wherein the cleaning plates 24 are in close contact with the inner wall of the hopper 1. One end of the cleaning plate 24 is fixedly connected to the gear ring 23. The ends of the two cleaning plates 24 that are close to each other are fixedly connected to the same connecting plate 25, wherein the connecting plate 25 can connect the two cleaning plates 24. Two first stirring plates 26 are fixedly connected to the top of the connecting plate 25, wherein the first stirring plates 26 and the connecting plate 25 are perpendicular to each other. When it is necessary to stir the silicon carbide fine powder in hopper 1, the operator turns on motor 21. Motor 21 drives gear 22 to rotate via reducer. Gear 22 rotates gear ring 23 and cleaning plate 24. Cleaning plate 24 cleans the inner wall of hopper 1 to prevent silicon carbide fine powder from sticking to the inner wall of hopper 1. At this time, the first stirring plate 26 rotates vertically inside hopper 1 under the drive of connecting plate 25, which achieves the effect of loosening silicon carbide fine powder in hopper 1. The vertical rotation of the first stirring plate 26 in hopper 1 by stirring device 2 achieves the effect of loosening silicon carbide fine powder, avoiding bridging of silicon carbide fine powder in hopper 1, which would affect the normal feeding of silicon carbide fine powder.

[0028] Reference Figure 1-4As shown, a triangular plate 27 is fixedly connected to the upper surface of the connecting plate 25, with the tip of the triangular plate 27 away from the connecting plate 25. The triangular plate 27 guides the connecting plate 25, preventing silicon carbide powder from accumulating on its upper surface. Two symmetrical extensions 28 are fixedly connected to one end of the first stirring plate 26, with the cross-section of each extension 28 being "V"-shaped. The extensions 28 increase the contact area between the first stirring plate 26 and the silicon carbide powder, thereby improving the stirring effect of the first stirring plate 26 on the silicon carbide powder. Limiting rings 29 are provided on both sides of the toothed ring 23, with two limiting rings 29 fixedly connected to the hopper 1. The limiting rings 29 limit the toothed ring 23, preventing it from shaking and causing misalignment between the toothed ring 23 and the gear 22.

A coil spring 34 is sleeved on the arc surface of the rotating rod 31. The two ends of the coil spring 34 are fixedly connected to the support plate 32 and the inner wall of the hopper 1, respectively. When the connecting plate 25 rotates, it rests against the support plate 32. The support plate 32 rotates the rotating rod 31 and the second stirring plate 33. The coil spring 34 deforms. When the connecting plate 25 moves past the support plate 32, under the action of the return spring force of the coil spring 34, the rotating rod 31, the support plate 32, and the second stirring plate 33 rotate back to their original positions. As the connecting plate 25 rotates continuously, the second stirring plate 33 rotates laterally back and forth, achieving the effect of loosening the silicon carbide fine powder. The second stirring plate 33, set by the auxiliary device 3, rotates laterally repeatedly inside the hopper 1, further stirring the silicon carbide fine powder in the hopper 1 and improving the loosening effect of the silicon carbide fine powder.

One end of the protective tube 35 is fixedly connected to the inner wall of the hopper 1, while the other end is rotatably connected to the support plate 32. By setting the protective tube 35, the coil spring 34 is protected, preventing silicon carbide fine powder from sticking to the coil spring 34.

[0031] Working principle: When silicon carbide fine powder needs to be processed, the operator places the silicon carbide fine powder into the hopper 1. The operator turns on the motor 21, which drives the gear 22 to rotate through the reducer. The gear 22 rotates the gear ring 23 and the cleaning plate 24. The limiting rings 29 on both sides of the gear ring 23 achieve the effect of limiting the gear ring 23. The cleaning plate 24 cleans the inner wall of the hopper 1 to prevent the silicon carbide fine powder from sticking to the inner wall of the hopper 1. At this time, the first stirring plate 26 and the extension piece 28 rotate vertically inside the hopper 1 under the drive of the connecting plate 25, which achieves the effect of loosening the silicon carbide fine powder in the hopper 1. The first stirring plate 26 set by the stirring device 2 rotates vertically in the hopper 1 to achieve the effect of loosening the silicon carbide fine powder, avoiding the bridging phenomenon of silicon carbide fine powder in the hopper 1, which would affect the normal feeding of silicon carbide fine powder.

When the connecting plate 25 moves past the support plate 32, under the action of the return spring force of the coil spring 34, the rotating rod 31, the support plate 32, and the second stirring plate 33 rotate back to their original positions. As the connecting plate 25 continues to rotate, the second stirring plate 33 rotates laterally back and forth, achieving the effect of loosening the silicon carbide fine powder.
