Abstract
Description
Technical Field
[0001] The embodiments disclosed herein relate to the technical field of mixing machines, specifically to a heat-resistant mixing machine for the production of silicon carbide continuous sliding plate. Background Technology
[0002] In the production process of silicon carbide continuous sliding upper slide plates, the mixing process is a key step that determines the product's performance and quality. Silicon carbide continuous sliding upper slide plates must possess excellent high-temperature resistance, wear resistance, and impact resistance, which places extremely high demands on the mixing effect of the mixing machine.
[0003] Currently, most mixing machines used in the production of silicon carbide continuous sliding plate uppers employ simple stirring structures, which cannot adequately disperse raw rubber and chemicals during mixing. Raw rubber has high viscosity and elasticity, while chemicals are mostly in powder or granular form. The significant differences in their physical properties make it difficult for ordinary stirring paddles to achieve uniform mixing, easily leading to problems such as chemical agglomeration and uneven raw rubber dispersion. This results in unstable performance of the final compound, affecting the quality of the finished silicon carbide continuous sliding plate upper. Furthermore, traditional mixing machines have many dead zones, hindering material flow within the mixing chamber. In some areas, the raw rubber and chemicals cannot be effectively mixed, further reducing the uniformity of the mixture.
[0004] In the discharge stage, the design flaws of traditional mixing machines are equally apparent. Due to the unreasonable structure of the mixing chamber, the mixed material cannot be completely discharged, and a large amount of residual material adheres to the walls, agitator, and corners of the mixing chamber. This residual material not only wastes raw materials but may also deteriorate due to prolonged retention, affecting the quality of the next batch of mixed rubber. Cleaning the residual material requires a lot of manpower and time, increasing production costs and reducing production efficiency. Utility Model Content
[0005] To overcome the above-mentioned defects, the embodiments of this disclosure provide a heat-resistant mixing machine for the production of silicon carbide continuous sliding plate, which solves the technical problem that most mixing machines used in the production of silicon carbide continuous sliding plate adopt a simple stirring structure and cannot fully disperse raw rubber and agents during mixing.
[0006] According to one aspect, at least one embodiment of this disclosure provides a heat-resistant mixing mill for the production of silicon carbide continuous sliding plate, comprising:
[0007] The outer shell and the inner liner, wherein the inner liner is movably connected to the outer shell;
[0008] A scraping and discharging assembly is disposed within the outer shell and the inner liner;
[0009] A feeding and mixing assembly is disposed on the housing;
[0010] The feeding and mixing assembly includes a top frame, which is fixed to the outer wall of the outer shell. One end of the top frame is located at the top of the outer shell and the inner liner. A central shaft is rotatably connected to the top frame by electric drive. A stirring rack is provided on the central shaft. An external gear is provided around the top of the inner liner. A drive gear that is rotatably driven by electric drive is provided on the outside of the outer shell.
[0011] As a further technical solution, an eccentric shaft is electrically driven to rotate on the top frame, and a spiral blade is provided on the eccentric shaft. A feeding hopper is provided on the top of the top frame, and a feeding pipe is provided at the lower end of the feeding hopper.
[0012] As a further technical solution, the scraping and discharging assembly includes several outer frames, each of which is fixed around the side surface of the outer shell. One end of each outer frame is provided with an inner ring frame, which is located in the inner liner.
[0013] As a further technical solution, the bottom of the inner ring frame is provided with several cleaning scrapers, the bottom of the outer shell is provided with a discharge pipe, and a spiral pusher is provided inside the discharge pipe.
[0014] As a further technical solution, a slide rail is provided around the top of the outer shell. The slide rail has a circular structure, and the inner liner is slidably connected to the slide rail.
[0015] As a further technical solution, the scraping frame has a triangular cross-section, and the side end face of the scraping frame slides against the inner wall of the inner liner.

[0017] As a further technical solution, a raised layer is provided at the lower end of the inner wall of the outer shell, and the raised layer is in a sealed sliding fit with the lower end face of the inner liner.
[0018] The beneficial effects of the embodiments disclosed herein are as follows:
[0019] In this disclosure, the feeding and mixing assembly achieves thorough mixing of raw rubber and reagents through the coordinated action of multiple components. The central shaft drives the mixing frame to stir the materials, the drive gear meshes with the external gear to drive the inner liner to rotate and form a revolution, and the spiral blades on the eccentric shaft cause the materials to flow in a spiral shape. The combination of these three motion modes shears, kneads and tumbles the materials in three-dimensional space, breaking up the agglomeration of raw rubber and reagents, eliminating mixing dead zones, and solving the problems of simple mixing structure and insufficient mixing in traditional mixing machines. Compared with traditional methods, it significantly improves mixing efficiency and uniformity, and ensures stable performance of the mixed rubber. Attached Figure Description

[0031] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0032] like Figures 1-4 As shown, it illustrates a heat-resistant mixing mill for producing silicon carbide continuous sliding plate according to an embodiment of the present disclosure, comprising:
[0033] The outer shell 1 and the inner liner 2 are movably connected to the outer shell 1;
[0034] A scraping and discharging assembly 4 is disposed in the outer shell 1 and the inner liner 2;
[0035] Feeding and mixing assembly 3, wherein the feeding and mixing assembly 3 is disposed on the outer shell 1;
[0036] The feeding and mixing assembly 3 includes a top frame 3-1, which is fixed to the outer wall of the outer shell 1. One end of the top frame 3-1 is located at the top of the outer shell 1 and the inner liner 2. A central shaft 3-2 is electrically driven and rotatably connected to the top frame 3-1. A stirring rack 3-3 is provided on the central shaft 3-2. An external gear 3-4 is provided around the top of the inner liner 2. A drive gear 3-5 is electrically driven and rotatably connected to the outside of the outer shell 1. An eccentric shaft 3-6 is electrically driven and rotatably connected to the top frame 3-1. A spiral blade 3-7 is provided on the eccentric shaft 3-6. A feeding hopper 3-8 is provided at the top of the top frame 3-1. A feeding pipe 3-9 is provided at the lower end of the feeding hopper 3-8.
[0037] In some examples, a feeding and mixing assembly 3 is designed to achieve rapid feeding and thorough mixing. The feeding hopper 3-8 on the top frame 3-1 and the feeding pipe 3-9 form an efficient feeding channel, which can quickly feed raw rubber and chemicals into the inner liner 2. The stirring frame 3-3 driven by the central shaft 3-2 rotates under motor control to stir and disperse the materials. At the same time, the drive gear 3-5 meshes with the external gear 3-4 on the top of the inner liner 2, driving the inner liner 2 to rotate itself, forming a revolution motion of the materials. The spiral blades 3-7 on the eccentric shaft 3-6, driven by electricity, lift and push the materials along the wall of the inner liner 2 downwards, generating a spiral material flow trajectory. The synergistic effect of these three motion modes allows the raw rubber and chemicals to be continuously sheared, kneaded, and turned in three-dimensional space, breaking up material agglomeration, effectively eliminating mixing dead zones, and achieving a thorough and uniform mixing effect. Compared with the traditional single stirring mode, the mixing efficiency and uniformity are significantly improved.
[0038] like Figures 1-4 As shown in the figure, the cleaning and scraping discharge assembly 4 in this embodiment includes several outer frames 4-1, each of which is fixed around the side surface of the outer shell 1. An inner ring frame 4-2 is provided at one end of the outer frame, and the inner ring frame 4-2 is located in the inner liner 2. Several cleaning frames 4-3 are provided at the bottom of the inner ring frame 4-2. A discharge pipe 4-4 is provided at the bottom of the outer shell 1, and a spiral pusher 4-5 is provided inside the discharge pipe 4-4.
[0039] In some examples, a scraping and discharging assembly 4 is designed to ensure the cleanliness of the inner wall of the inner liner 2 and the effect of rapid material discharge. An outer frame 4-1, fixed to the side surface of the outer shell 1, supports the inner ring frame 4-2, ensuring its stable position inside the inner liner 2. After mixing is complete, the scraping frame 4-3 at the bottom of the inner ring frame 4-2 fits tightly against the inner wall of the inner liner 2. As the inner liner 2 continues to rotate, the scraping frame 4-3 thoroughly scrapes off the residual material adhering to the wall and corners of the inner liner 2. Simultaneously, the spiral pusher 4-5 inside the discharge pipe 4-4 at the bottom of the outer shell 1 is activated, rapidly pushing the mixed material and the scraped-off residual material together along the discharge pipe 4-4 to the discharge port. This design, combining scraping and pushing, not only thoroughly discharges the material inside the inner liner 2, preventing residual material from deteriorating and affecting subsequent production, but also significantly shortens the discharge time, reduces manual cleaning steps, improves equipment operating efficiency, and provides a reliable guarantee for the continuous production of silicon carbide continuous sliding plate.
[0040] For example, such as Figure 4 As shown, a slide rail 5 is provided around the top of the outer shell 1. The slide rail 5 has a circular structure, and the inner liner 2 is slidably connected to the slide rail 5.
[0041] In some examples, by providing a slide rail 5, the resistance between the outer shell 1 and the inner liner 2 can be reduced, allowing the inner liner 2 to rotate stably and smoothly.
[0042] For example, such as Figure 2 As shown, the scraping frame 4-3 has a triangular cross-section, and the side end face of the scraping frame 4-3 slides against the inner wall of the inner liner 2.
[0043] In some examples, the triangular structure reduces the contact area with the inner wall of the inner liner 2, resulting in better scraping and no residue. The sharp edges of the triangular scraper 4-3 can penetrate deep into the grooves and crevices of the inner liner 2 wall to powerfully scrape away adhering materials; the smaller contact area creates concentrated pressure during sliding, enhancing scraping ability, and even dried-up materials can be effectively peeled off. This design ensures that the scraper 4-3 achieves thorough cleaning without dead angles when moving in close contact with the inner wall of the inner liner 2, eliminating material residue and providing a clean environment for the next mixing operation.
[0044] For example, such as Figure 3 As shown, an anti-blocking bracket 6 is provided at the lower end of the central shaft 3-2.
[0045] In some examples, the anti-blocking frame 6 is installed to maintain continuous agitation during the discharge process, accelerating the downward flow and improving the discharge efficiency. The anti-blocking frame 6 employs a staggered, hollowed-out structure design, rotating at the bottom of the inner liner 2 under the drive of the central shaft 3-2, effectively breaking up clumps and accumulations formed by the material's viscosity. Its continuous agitation keeps the material in a loose, flowing state, which, combined with the spiral pusher 4-5 of the lower discharge pipe 4-4, further improves material conveying efficiency, avoids discharge obstruction caused by blockages, and ensures the rapid and thorough discharge of the mixed material.
[0046] For example, such as Figure 3 As shown, a raised layer 7 is provided at the lower end of the inner wall of the outer shell 1, and the raised layer 7 is sealed and slidably attached to the lower end face of the inner liner 2.
[0047] In some examples, the presence of a raised layer 7 increases the seal between the inner liner 2 and the outer shell 1, preventing material from entering gaps and affecting the rotation of the inner liner 2. The raised layer 7 fits tightly against the lower surface of the inner liner 2, forming a physical barrier that blocks material particles and dust generated during the mixing process. Even under high-speed mixing conditions, the sealing and sliding effect of the raised layer 7 effectively prevents material from entering gaps, reduces the rotational resistance of the inner liner 2 caused by foreign objects getting stuck, ensures stable operation of the inner liner 2, extends the service life of the equipment, and guarantees efficient and continuous mixing operations.
[0048] In actual use: After fixing the outer shell 1, the inner liner 2 is movably connected inside the outer shell 1. A circular slide rail 5 is installed around the top of the outer shell 1, allowing the inner liner 2 to slide on the slide rail 5. A scraping and discharging assembly 4 is installed in the outer shell 1 and the inner liner 2. A feeding and mixing assembly 3 is installed on the outer shell 1. The top frame 3-1 is fixed to the outer wall of the outer shell 1, with one end located at the top of the outer shell 1 and the inner liner 2. The top frame 3-1 is electrically driven to rotate and connect the central shaft 3-2 and the eccentric shaft 3-6. A stirring frame 3-3 is installed on the central shaft 3-2, and a spiral blade 3-7 is installed on the eccentric shaft 3-6. A feeding hopper 3-8 is installed on the top of the top frame 3-1 and connected to the feeding pipe 3-9. An external gear 3-4 is installed around the top of the inner liner 2. An electrically driven rotating... Drive gear 3-5, outer frame 4-1 of cleaning and scraping discharge assembly 4 is fixed around the side surface of outer shell 1. One end of outer frame 4-1 is equipped with inner ring frame 4-2, and the bottom of inner ring frame 4-2 is equipped with cleaning frame 4-3. The bottom of outer shell 1 is equipped with discharge pipe 4-4 and spiral pusher 4-5 is installed in the pipe. When in use, raw rubber and agents are fed into inner liner 2 from feeding hopper 3-8 through feeding pipe 3-9. Electric drive central shaft 3-2 drives mixing frame 3-3 to rotate. At the same time, drive gear 3-5 meshes with outer gear 3-4 to drive inner liner 2 to rotate. Eccentric shaft 3-6 drives spiral blade 3-7 to lift and push the material. After mixing, cleaning frame 4-3 scrapes off residual material against inner wall of inner liner 2. Spiral pusher 4-5 sends material out from discharge pipe 4-4.
