Abstract
Description
Technical Field
[0001] This utility model relates to the field of mixing device technology, specifically to a silicon carbide processing mixing machine. Background Technology
[0002] Silicon carbide is an inorganic material produced by high-temperature smelting of quartz sand, petroleum coke, and wood chips in an electric resistance furnace. It is a semiconductor that exists in nature as the extremely rare mineral moissanite. Processing silicon carbide requires stirring, a process of mixing two or more substances, typically achieved using a mechanical agitator. Publications CN222384631U and CN222624257U disclose related structures and contents for silicon carbide mixing. However, current mixing devices mainly employ vertically arranged mixing units, with the entire mixing cylinder vertically aligned and the silicon carbide material piled at the bottom. Since silicon carbide is not a liquid fluid, this accumulation results in uneven mixing of the silicon carbide at the bottom. Often, increasing the mixing time is used to improve the mixing effect, which reduces mixing efficiency. Therefore, this application proposes a silicon carbide processing mixer that improves mixing efficiency while ensuring the mixing effect. Utility Model Content

[0006] Furthermore, an arc-shaped rack is installed on the frame, and a transmission gear is installed at the end of the stirring rod. The transmission gear meshes with the arc-shaped rack during the rotation of the mixing cylinder.
[0007] Furthermore, the discharge port has a frame-shaped structure and is distributed along the axial direction of the mixing cylinder on the outer periphery of the mixing cylinder.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.
[0021] like Figures 1-6 As shown in the figure, an embodiment of the present invention discloses a silicon carbide processing mixing machine, including a frame 1. Two hollow tubes 2 are mounted on the frame 1 via bearing seats. The two hollow tubes 2 are horizontally coaxially distributed, with both ends of the hollow tubes 2 being open. A mixing cylinder 3 is mounted on the two hollow tubes 2, and the hollow tubes 2 and the mixing cylinder 3 are coaxial and connected. The internal space of the mixing cylinder 3 is used to contain silicon carbide raw materials. A discharge port 4 is constructed on the outer periphery of the mixing cylinder 3. A stirring rod 5 is mounted on the mixing cylinder 3 in a circular array along the axis of the mixing cylinder 3. A feeding mechanism 9 is inserted inside the hollow tubes 2, and silicon carbide is fed into the mixing cylinder 3 along the axis of the mixing cylinder 3 through the feeding mechanism 9. The frame 1 of the present invention is also equipped with a first motor 8 and a second motor 10. Both the first motor 8 and the second motor 10 are geared motors. The output shaft of the first motor 8 is connected to one of the hollow tubes 2, thereby driving the hollow tube 2 to rotate. Specifically, the worm gear in the reducer is sleeved on the hollow tube 2. The feeding mechanism 9 is used without affecting the operation of the feeding mechanism 9. During use, the feeding mechanism 9 transports the silicon carbide raw material into the mixing cylinder 3. The silicon carbide raw material inside the mixing cylinder 3 is spread out along the axis of the mixing cylinder 3. The spread silicon carbide raw material is shallow and has been dispersed. As the mixing cylinder 3 rotates, it does not rotate in a complete circle, but rather in an arc swing, that is, it rotates clockwise for a certain angle and then counterclockwise for a certain angle. At this time, the silicon carbide raw material inside the mixing cylinder 3 can be shaken and turned. During this process, the stirring rod 5 can stir the silicon carbide raw material, further mixing the silicon carbide raw material in motion, thereby improving the stirring effect. Since the silicon carbide raw material in this application is shallow and in a spread state, and the mixing cylinder 3 rotates left and right to drive the silicon carbide raw material to move, and assists the stirring rod 5 in mixing, the mixing effect is guaranteed while the mixing efficiency is improved.
[0022] like Figure 2 and Figure 3 As shown, in some embodiments, an arc-shaped rack 6 is installed on the frame 1, and a transmission gear 7 is installed at the end of the stirring rod 5. The transmission gear 7 meshes with the arc-shaped rack 6 as the mixing cylinder 3 rotates. The power for the rotation of the stirring rod 5 comes from the rotation of the mixing cylinder 3. When the transmission gear 7 contacts the arc-shaped rack 6, as the mixing cylinder 3 rotates, the transmission gear 7 rolls along the arc-shaped rack 6, thereby driving the stirring rod 5 to rotate. It should be clear that no matter how the mixing cylinder 3 rotates, the silicon carbide raw material inside the mixing cylinder 3 is always close to the bottom of the mixing cylinder 3 due to gravity and influence. Thus, with the two types of rotation of the stirring rod 5, one is with the mixing cylinder 3 and the other is its own rotation, all the stirring rods 5 can fully stir the silicon carbide raw material as they rotate left and right with the mixing cylinder 3.
[0023] like Figures 1-2 As shown, in some embodiments, the discharge port 4 has a frame-shaped structure and is distributed along the axial direction of the mixing cylinder 3 on the outer periphery of the mixing cylinder 3. Since the mixing cylinder 3 rotates left and right when in the stirring state, but when in the discharging state, it needs to rotate so that the discharge port 4 is vertically downward to facilitate the discharge of the silicon carbide raw material inside the mixing cylinder 3. Based on this structural design, the stirring rod 5 does not need to be installed at the position corresponding to the discharge port 4. Specifically, it can be as follows... Figure 5 As shown, the distribution of the stirring rods 5 is exactly matched with the rotation arc of the mixing cylinder 3 when it is in the stirring state.
[0024] like Figure 2 As shown, in some embodiments, the frame 1 is provided with a movable notch 11 for the transmission gear 7 to pass through. Considering that the mixing cylinder 3 itself rotates, the stirring rod 5 and the transmission gear 7 need to pass through the frame 1, so the design of the movable notch can avoid interfering with the movement of the transmission gear 7.
[0025] like Figure 6 As shown, in some embodiments, the feeding mechanism 9 includes a conveying pipe 901 mounted on the frame 1. The conveying pipe 901 passes through two hollow pipes 2 and is coaxially distributed. An auger conveying shaft 904 is rotatably installed inside the conveying pipe 901. The conveying pipe 901 is configured with a discharge port 902 and a feed pipe 905. The output shaft of the second motor 10 is connected to the auger conveying shaft 904. Silicon carbide raw material is supplemented to the conveying pipe 901 through the feed pipe 905. The second motor 10 drives the auger conveying shaft 904 to rotate, conveying the silicon carbide raw material. As the silicon carbide raw material moves, it is discharged into the mixing cylinder 3 through the discharge port 902.
[0026] like Figure 6 As shown, in order to achieve the dispersion of silicon carbide raw material inside the mixing cylinder 3, the discharge port 902 is composed of multiple rectangular notches arranged in a linear array on the conveying pipe 901. As the silicon carbide raw material is conveyed, it will gradually enter the interior of the mixing cylinder 3 through each rectangular notch, thus distributing along the axial direction of the entire mixing cylinder 3. This can prevent the silicon carbide raw material from accumulating to a thick depth inside the mixing cylinder 3, which is beneficial for mixing and stirring. The conveying pipe 901 has a discharge notch 903 on its peripheral side outside the mixing cylinder 3. The purpose of the discharge notch 903 is to discharge the silicon carbide raw material that has not entered the interior of the mixing cylinder 3 through the rectangular notch from the conveying pipe 901, and after collection, it is conveyed back to the feed pipe 905.
[0027] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
