Description

Technical Field

[0001] This utility model relates to the field of mixing equipment technology, and in particular to a homogenizer for processing silicon carbide slurry. Background Technology

[0002] Silicon carbide, also known as corundum or silicon carbide stone, is produced by high-temperature smelting of raw materials such as quartz sand, petroleum coke (or coal coke), and sawdust (salt needs to be added when producing green silicon carbide) in an electric resistance furnace. Among contemporary non-oxide high-tech refractory materials such as C, N, and B, silicon carbide is the most widely used and economical.

[0003] In silicon carbide production, the mixing of various raw materials, or homogenization, is a crucial process. The quality of homogenization directly affects the quality of the fired product, primarily the uniformity of its internal texture. Generally, traditional homogenization equipment simply uses a rotating shaft to agitate the raw materials in a circumferential direction. At most, tilting the agitator blades can achieve a slight up-and-down turning effect. This mixing method has a weak turning effect in the vertical direction, and the mixing time is relatively long to ensure thorough mixing, thus its work efficiency needs improvement. Utility Model Content

[0004] The purpose of this invention is to provide a homogenizing machine for processing silicon carbide slurry, so as to solve the problems of long mixing time, weak turning effect in the vertical direction, and insufficient work efficiency of existing homogenizing equipment for silicon carbide slurry.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A homogenizer for processing silicon carbide slurry includes a material cylinder, a motor, and a stirring mechanism. The stirring mechanism is disposed inside the material cylinder, and its top is connected to the power output terminal of the motor. The motor is located at the top of the material cylinder.

[0007] The stirring mechanism includes a vertical shaft, a sleeve, a gear transmission structure, a rotating shaft, a ball head, and stirring blades. The vertical shaft is vertically installed at the center of the inner bottom of the material cylinder. The sleeve is fitted onto the vertical shaft. Multiple rotating shafts are symmetrically arranged and rotatably installed on the sleeve. The inner end of the rotating shaft is connected to the ball head. The ball head is slidably installed in the annular groove of the vertical shaft. The rotating shaft and the vertical shaft are connected through the gear transmission structure. The stirring blades are installed at the outer end of the rotating shaft.

[0008] A further technical solution is that a sealing ring is provided between the bottom of the vertical shaft and the bottom of the sleeve.

[0009] A further technical solution is that the gear transmission structure is a bevel gear pair.

[0010] A further technical solution is: a convex ring is provided on the vertical shaft, and the outer circumferential surface of the convex ring is adapted to the inner circumferential surface of the sleeve.

[0011] A further technical solution is that the rotating shaft is threadedly connected to the ball head.

[0012] A further technical solution is that the maximum diameter of the ball head is greater than the inlet width of the annular groove.

[0013] A further technical solution is that the stirring blade is composed of three plates in a U-shaped structure.

[0014] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects:

[0015] This invention proposes a homogenizer for processing silicon carbide slurry. The homogenizer's stirring mechanism can agitate the silicon carbide raw material in the cylinder in a circumferential direction, and each stirring blade can also rotate. This adds an up-and-down stirring effect to the circumferential stirring, effectively ensuring that most of the raw material is mixed during one revolution, greatly improving work efficiency. Furthermore, this homogenizer does not require an additional power source and is relatively simple to use. Attached Figure Description

[0027] This implementation example Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a homogenizer for processing silicon carbide slurry includes a material cylinder 1, a motor 2, and a stirring mechanism 3. The stirring mechanism 3 is disposed inside the material cylinder 1, and its top is connected to the power output end of the motor 2. The motor 2 is disposed at the top of the material cylinder 1.

[0028] The stirring mechanism 3 includes a vertical shaft 4, a sleeve 5, a gear transmission structure 6, a rotating shaft 7, a ball head 8, and a stirring blade 9. The vertical shaft 4 is vertically installed at the center of the inner bottom of the material cylinder 1. The sleeve 5 is fitted onto the vertical shaft 4. Multiple rotating shafts 7 are symmetrically arranged and rotatably installed on the sleeve 5. The inner end of the rotating shaft 7 is connected to the ball head 8. The ball head 8 is slidably installed in the annular groove 10 of the vertical shaft 4. The rotating shaft 7 and the vertical shaft 4 are connected by the gear transmission structure 6. The stirring blade 9 is installed on the outer end of the rotating shaft 7.

[0029] The working process of this utility model is as follows: First, various raw materials used for producing silicon carbide are put into the material cylinder 1. The motor 2 is started to drive the stirring mechanism 3 to work. The sleeve 5 rotates on the vertical shaft 4, and the stirring blades 9 and the rotating shaft 7 also rotate in the circumferential direction with the sleeve 5. At the same time, the gear transmission structure 6, under the combined action of the vertical shaft 4 and the sleeve 5, causes the rotating shaft 7 to rotate around its own axis. The rotating shaft 7 also rotates the stirring blades 9. When the rotating shaft 7 rotates, the ball head 8 is used to prevent the rotating shaft 7 from moving. This stirring mechanism 3 can stir the silicon carbide raw materials in the material cylinder 1 in the circumferential direction, and each stirring blade 9 can also rotate. That is, on the basis of circumferential stirring, the effect of up and down stirring is added. In the process of stirring one revolution, it can effectively ensure that most of the raw materials are stirred and mixed, which greatly improves the working efficiency. In addition, this material homogenizer does not require an additional power source and is relatively simple to use.

[0030] Preferably, a sealing ring 11 is provided between the bottom of the vertical shaft 4 and the bottom of the sleeve 5.

[0031] To prevent silicon carbide raw material in barrel 1 from entering between vertical shaft 4 and sleeve 5, ensuring stable operation and lifespan of the components.

[0032] Preferably, the gear transmission structure 6 is a bevel gear pair.

[0033] One bevel gear is mounted on the vertical shaft 4, and the other bevel gear is mounted on the rotating shaft 7. The two bevel gears mesh with each other to form a transmission structure of a bevel gear pair. Under the combined action of the vertical shaft 4 and the rotating sleeve 5, the rotating shaft 7 will rotate along its own axis.

[0034] Preferably, a convex ring 12 is provided on the vertical shaft 4, and the outer peripheral surface of the convex ring 12 is adapted to the inner peripheral surface of the sleeve 5.

[0035] When the sleeve 5 rotates on the vertical shaft 4, the convex ring 12 serves as a positioning element.

[0036] Preferably, the rotating shaft 7 is threadedly connected to the ball head 8.

[0037] Threaded connections facilitate component disassembly and assembly, as well as later maintenance and replacement.

[0038] Preferably, the maximum diameter of the ball head 8 is greater than the inlet width of the annular groove 10.

[0039] The ball head 8 will not slip when sliding within the annular groove 10.

[0040] Preferably, the stirring blade 9 consists of three plates in a U-shaped structure.

[0041] The U-shaped stirring blade 9 can better turn the material as it rotates with the rotating shaft 7. Of course, the stirring blade 9 can also be other shapes or structures, as long as it can achieve the effect of turning the material when rotating.

[0042] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
