Description

Technical Field

[0001] This utility model relates to the field of conveying auger technology, and in particular to a silicon carbide micro powder conveying auger. Background Technology

[0002] Silicon carbide is an inorganic substance produced by high-temperature smelting of raw materials such as quartz sand, petroleum coke, and sawdust in an electric resistance furnace. Silicon carbide also exists in nature as a rare mineral, moissanite. Among non-oxide high-tech refractory raw materials such as C, N, and B, silicon carbide is the most widely used and economical one, and can be called corundum or refractory sand.

[0003] For example, Chinese Patent Publication No. CN219384070U discloses a raw material conveying device for grinding silicon carbide micro powder, which includes: a silicon carbide raw material conveying box, with support columns installed at the four corners of the bottom of the silicon carbide raw material conveying box, and bases installed at the bottom of the four support columns; a conveying pipe is installed at the bottom of one end of the silicon carbide raw material conveying box; a discharge port is opened at the middle of the top of the silicon carbide raw material conveying box, and a rotating rod is rotatably installed between the inner walls of the discharge port; multiple stirring rollers are installed on the surface of the rotating rod; one end of the rotating rod extends into the inner cavity of the silicon carbide raw material conveying box and is equipped with a motor; a middle plate is installed in the middle of the inner cavity of the silicon carbide raw material conveying box, and a rotating block is rotatably installed at the top of the middle plate.

[0004] However, in the existing technology, when conveying a large amount of silicon carbide micro powder, the silicon carbide micro powder is easy to get clogged at the feed inlet. The high conveying volume will cause the micro powder to accumulate at the feed inlet and not have time to enter the pushing area of ​​the spiral blade, thus causing the feed inlet to be blocked. At the same time, the mutual compression and friction between the micro powders increase, which easily forms agglomerates, leading to blockage inside the conveying cylinder. Therefore, a silicon carbide micro powder conveying auger is proposed. Utility Model Content

[0005] The purpose of this invention is to solve the problems existing in the prior art, such as blockage of the feed inlet, increased mutual compression and friction between micro powders, easy formation of clumps, and subsequent blockage inside the conveying cylinder. Therefore, a silicon carbide micro powder conveying auger is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a silicon carbide micro powder conveying auger, including a base plate, a conveying mechanism provided at the upper end of the base plate, an anti-blocking mechanism provided at the upper end of the base plate, and the conveying mechanism including a conveying cylinder and a feeding frame;

The lower part of the second spiral blade is located inside the guide cylinder and the connecting frame, while the upper part is located inside the feeding hopper.

[0008] Preferably, a support frame plate is fixedly installed at one end of the feeding cylinder, a drive motor is fixedly installed at the upper end of the support frame plate, a rotating shaft is rotatably installed through both ends of the feeding cylinder, a rotating rod is fixedly installed between the two sets of rotating shafts, and a first spiral blade is fixedly installed on the outer wall of the rotating rod.

[0009] Preferably, multiple sets of support rods are fixedly installed on the lower surface of the feed hopper, and the upper end of the vertical rod passes through the lower end of the cross plate and is fixed to the output end of the variable speed motor.

[0010] Preferably, the lower ends of the multiple sets of support rods are all fixed to the upper end of the base plate, and the lower end of the connecting frame is fixed to the upper end of the feeding frame.

[0011] Preferably, two sets of support seats are fixedly installed at the lower end of the feeding cylinder, and the lower end of the feeding frame is fixed to the opening at the upper end of the feeding cylinder.

[0012] Preferably, one end of one set of rotating shafts passes through one end of the support frame plate and is fixed to the output end of the drive motor, and the first spiral blade is disposed inside the conveying cylinder.

[0013] Preferably, the lower ends of both sets of support seats are fixed to the upper ends of the base plate, and the lower end of the support frame plate is fixed to the upper ends of the base plate.

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

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1: As Figure 1 As shown in Figure 4, this utility model provides a silicon carbide micro powder conveying auger, including a base plate 1, a conveying mechanism 2 is provided at the upper end of the base plate 1, and an anti-blocking mechanism 3 is provided at the upper end of the base plate 1. The conveying mechanism 2 includes a conveying cylinder 21 and a feeding frame 22.

[0024] The anti-blocking mechanism 3 includes a feeding hopper 31, a guide cylinder 32 fixedly installed at the lower end of the feeding hopper 31, a connecting frame 33 fixedly installed at the lower end of the guide cylinder 32, a cross plate 34 fixedly installed at the upper end of the feeding hopper 31, a variable speed motor 35 fixedly installed at the upper end of the cross plate 34, a vertical rod 36 is provided inside the guide cylinder 32, a second spiral blade 37 is fixedly installed on the outer wall of the vertical rod 36, the lower part of the second spiral blade 37 is located inside the guide cylinder 32 and the connecting frame 33, and the upper part is located inside the feeding hopper 31, multiple sets of support rods 38 are fixedly installed on the lower surface of the feeding hopper 31, the upper end of the vertical rod 36 passes through the lower end of the cross plate 34 and is fixed to the output end of the variable speed motor 35, the lower ends of the multiple sets of support rods 38 are all fixed to the upper end of the base plate 1, and the lower end of the connecting frame 33 is fixed to the upper end of the feeding frame 22.

[0025] The specific settings and functions of this embodiment are described in detail below. By starting the variable speed motor 35, the output end of the variable speed motor 35 drives the vertical rod 36 to rotate, and the vertical rod 36 drives the second spiral blade 37 to rotate. This allows the silicon carbide micro powder inside the feed hopper 31 to be transported to the inside of the guide cylinder 32, and then transported to the inside of the conveying cylinder 21 through the connecting frame 33 and the feed frame 22. This prevents the silicon carbide micro powder from accumulating inside the feed hopper 31 and from clogging at the connection between the guide cylinder 32 and the feed hopper 31. It can quickly transport the silicon carbide micro powder to the inside of the conveying mechanism 2. At the same time, it can prevent the silicon carbide micro powder from being squeezed and rubbed against each other, preventing the formation of lumps, and further preventing clogging inside the guide cylinder 32.

[0026] By installing a cross plate 34 at the upper end of the feed hopper 31, the cross plate 34 can easily support the variable speed motor 35. The setting of multiple sets of vertical rods 36 can support the feed hopper 31 and prevent the feed hopper 31 from separating from the guide cylinder 32.

[0027] Example 2: Figure 1 and Figure 4 As shown, the conveying mechanism 2 includes a conveying cylinder 21 and a feeding frame 22. A support frame plate 24 is fixedly installed at one end of the conveying cylinder 21, and a drive motor 25 is fixedly installed at the upper end of the support frame plate 24. Rotating shafts 27 are rotatably installed through both ends of the conveying cylinder 21. A rotating rod 26 is fixedly installed in the middle of the two sets of rotating shafts 27. A first spiral blade 28 is fixedly installed on the outer wall of the rotating rod 26. Two sets of support seats 23 are fixedly installed at the lower end of the conveying cylinder 21. The lower end of the feeding frame 22 is fixed to the opening at the upper end of the conveying cylinder 21. One end of one set of rotating shafts 27 passes through one end of the support frame plate 24 and is fixed to the output end of the drive motor 25. The first spiral blade 28 is disposed inside the conveying cylinder 21. The lower ends of the two sets of support seats 23 are fixed to the upper end of the base plate 1, and the lower end of the support frame plate 24 is fixed to the upper end of the base plate 1.

[0028] The overall effect of this embodiment is that by starting the drive motor 25, the output end of the drive motor 25 drives one set of rotating shafts 27 to rotate. One set of rotating shafts 27 drives another set of rotating shafts 27 to rotate through the rotating rod 26, so that the two sets of rotating shafts 27 rotate inside the two ends of the feeding cylinder 21 respectively. At the same time, the rotating rod 26 also drives the first spiral blade 28 to rotate inside the feeding cylinder 21, thereby conveying the silicon carbide micro powder that falls into the feeding cylinder 21 and discharging it from the lower end of the feeding cylinder 21.

[0029] The support plate 24 can support the drive motor 25 and increase the stability of the drive motor 25 during operation, while the two sets of support seats 23 can support the conveying cylinder 21.

[0030] The operating method and working principle of this device are as follows: First, the silicon carbide powder is poured into the feed hopper 31. Then, the variable speed motor 35 and drive motor 25 are started. The output end of the variable speed motor 35 drives the vertical rod 36 to rotate, and the vertical rod 36 drives the second spiral blade 37 to rotate. This allows the silicon carbide powder inside the feed hopper 31 to be transported to the guide cylinder 32, and then transported to the conveying cylinder 21 through the connecting frame 33 and the feed frame 22. This prevents the silicon carbide powder from accumulating inside the feed hopper 31 and from clogging the connection between the guide cylinder 32 and the feed hopper 31. It can quickly transfer the silicon carbide powder to the conveying mechanism 2. This system prevents the silicon carbide micropowder from being squeezed and rubbed against each other, preventing the formation of lumps and further preventing blockage inside the feed cylinder 32. Finally, the output end of the drive motor 25 drives one set of rotating shafts 27 to rotate, and one set of rotating shafts 27 drives another set of rotating shafts 27 to rotate through the rotating rod 26, so that the two sets of rotating shafts 27 rotate inside the feed cylinder 21 at both ends respectively. At the same time, the rotating rod 26 also drives the first spiral blade 28 to rotate inside the feed cylinder 21, thereby conveying the silicon carbide micropowder that falls into the feed cylinder 21 and discharging it from the lower discharge end of the feed cylinder 21.

[0031] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. 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 this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
