Description

Technical Field

[0001] The utility model relates to the field of antioxidant preparation devices, and particularly to a composite antioxidant preparation device. Background Technique

[0002] The screw extrusion granulator plays an important role in the field of antioxidant production. It uses the rotational movement of the screw to efficiently compress antioxidant materials into particles, which not only improves production efficiency but also can adjust the particle size and shape according to needs. The equipment is easy to operate and maintain, and can be widely used in the granulation of different types of antioxidant materials. Its high-quality output products ensure the stability and reliability of the antioxidant particle quality, meeting market demands. The flexibility, efficiency, and adjustability of the screw extrusion granulator make it an essential and important equipment in antioxidant production.

[0003] During the granulation process of the spiral feeding granulator for antioxidants, key components such as the scraper play a crucial role in improving the uniformity and precision of the particles. However, in actual operation, in order to obtain a flatter cut surface, the scraper is often set to directly contact the discharge hole surface. This contact causes friction between the blade and the raw material as well as between the blade and the discharge hole surface, which in turn leads to a continuous rise in the blade temperature. The high-temperature blade not only shortens its service life but also easily adheres to the raw material, thus affecting the granulation precision and quality. Content of the Utility Model

[0004] Based on this, the purpose of the utility model is to provide a composite antioxidant preparation device to solve the technical problems that the blade with a higher temperature is likely to reduce the blade life, cause adhesion to the raw material, and result in poor granulation precision.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A composite antioxidant preparation device includes a device main body and a second motor. The output end of the second motor is provided with a transmission shaft, and the end of the transmission shaft is provided with a scraper mechanism. The scraper mechanism includes a sleeve, and three groups of blade bodies are arranged on the outer side of the sleeve. A semiconductor refrigerating sheet is arranged on one side of the surface of the blade body, a wind guide plate is arranged above the blade body, a limiting plate is arranged below the blade body, and a power supply is arranged on the transmission shaft.

[0006] By adopting the above technical solution, the semiconductor refrigerating sheet conducts cold air to the surface of the blade body, effectively reducing the blade temperature. This avoids the temperature rise of the blade due to frictional heat generation, thereby reducing the possibility of the raw material adhering to the blade due to high temperature.

[0007] Further, a wind channel is formed between the wind guide plate and the blade body, and the wind guide plate is obliquely arranged.

[0008] By adopting the above technical solution, the obliquely arranged air deflector is conducive to guiding and accelerating air flow, forming an effective air duct, which enhances the heat dissipation effect of the semiconductor refrigeration sheet, ensures its efficient operation, and thus maintains the low-temperature state of the blade body.

[0009] Furthermore, the limiting plate is arranged in an oblique structure for protecting the semiconductor refrigeration sheet.

[0010] By adopting the above technical solution, the oblique structure of the limiting plate can effectively protect the semiconductor refrigeration sheet from direct damage by external impacts or debris, reducing the risk of physical damage that the refrigeration sheet may encounter during operation, thereby ensuring its stable operation and extending its service life.

[0011] Furthermore, the semiconductor refrigeration sheet is electrically connected to the power supply through a wire, and the semiconductor refrigeration sheet is adhered to the blade body through a viscous thermal conductive silicone grease sheet.

[0012] By adopting the above technical solution, the direct electrical connection through the wire to the power supply ensures that the semiconductor refrigeration sheet can receive a stable and continuous power supply, which provides the necessary energy guarantee for the normal operation of the refrigeration sheet, enabling it to continuously provide a cooling effect for the blade body.

[0013] Furthermore, the three groups of blade bodies are arranged in an equidistant circular pattern along the central axis of the sleeve, and the sleeve is detachably connected to the transmission shaft.

[0014] By adopting the above technical solution, the equidistant circular arrangement of the blade bodies ensures the uniformity and consistency during the granulation process. The three groups of blades can evenly scrape the raw materials during rotation, making the produced granules of uniform size and improving the product quality.

[0015] Furthermore, on the other side of the surface of the blade body, there is a guiding piece for guiding the raw materials.

[0016] By adopting the above technical solution, the guiding piece can effectively guide the flow direction of the raw materials, ensuring that the raw materials can accurately enter the working area of the scraping mechanism, which improves the granulation accuracy and efficiency and avoids waste of raw materials.

[0017] Furthermore, a spiral feeding cylinder is arranged at the top of the device body. A first motor is arranged on one side of the spiral feeding cylinder, a discharge hole plate is arranged on the other side of the spiral feeding cylinder, a funnel is arranged at the top of the spiral feeding cylinder, and an electric control box is arranged on one side of the first motor.

[0018] By adopting the above technical solution, the spiral feeding cylinder can effectively convey raw materials from the funnel to the discharge orifice plate evenly and continuously, ensuring the continuity and stability of the granulation process. The first motor provides power for the spiral feeding cylinder, further ensuring the conveying efficiency.

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

[0020] With the scraper mechanism of the present utility model, the semiconductor refrigeration sheet conducts cold air to the surface of the blade body, effectively reducing the temperature of the blade body, directly solving the problem that the blade is prone to overheating after long-term operation, thus avoiding the adhesion of raw materials caused by the excessive temperature of the blade body, ensuring the quality and efficiency of granulation. At the same time, by reducing the blade temperature, the service life of the blade body is also extended, reducing equipment damage caused by high-temperature wear and corrosion, and reducing the maintenance cost. This not only improves the stability and reliability of the granulation process but also provides a strong guarantee for long-term continuous production. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The following will describe the embodiments of the present utility model according to its overall structure.

[0030] Embodiment 1:

[0031] A composite antioxidant preparation device, as Figures 1-4 shown, includes a device main body 1 and a second motor 501. A transmission shaft 502 is provided at the output end of the second motor 501. A scraper mechanism 6 is provided at the end of the transmission shaft 502. The scraper mechanism 6 includes a sleeve 608. Three groups of blade bodies 601 are provided on the outer side of the sleeve 608. A semiconductor refrigeration sheet 605 is provided on one side of the surface of the blade body 601. An air guide plate 604 is provided above the blade body 601. A limiting plate 603 is provided below the blade body 601. A power supply 607 is provided on the transmission shaft 502. The semiconductor refrigeration sheet 605 conducts cold air to the surface of the blade body 601, effectively reducing the blade temperature. This avoids the temperature rise of the blade due to frictional heat generation, thereby reducing the possibility of raw materials sticking to the blade due to high temperature. At the same time, keeping the blade at a low temperature also helps to improve the scraping efficiency and granulation quality. The low-temperature blade can cut the raw materials more smoothly, reduce adhesion and blockage, and ensure the continuity and uniformity of the granulation process. It not only extends the service life of the blade but also improves the overall granulation effect.

[0032] Refer to Figure 3 、 Figure 4, an air duct 609 is formed between the air deflector 604 and the blade body 601. The air deflector 604 is obliquely arranged. The obliquely arranged air deflector 604 is conducive to guiding and accelerating the air flow, forming an effective air duct 609. This enhances the heat dissipation effect of the thermoelectric cooler 605, ensures its efficient operation, and then keeps the blade body 601 in a low-temperature state. At the same time, through the air flow circulation in the air duct 609, the heat generated by the cooler can be taken away in time, preventing heat accumulation, thereby improving the working stability and durability of the entire scraper mechanism. It not only optimizes the heat dissipation performance but also provides guarantee for long-term and continuous high-load operation.

[0033] Embodiment 2:

[0034] Refer to Figure 3 、 Figure 4 , the limiting plate 603 is obliquely structured and is used to protect the thermoelectric cooler 605. The oblique structure of the limiting plate 603 can effectively protect the thermoelectric cooler 605 from direct damage by external impacts or debris, reducing the risk of physical damage that the cooler may encounter during operation, thereby ensuring its stable operation and extending its service life. At the same time, the limiting plate 603 can also guide the raw material flow to a certain extent, preventing the raw material from directly contacting the thermoelectric cooler 605, further enhancing the protection effect. This comprehensive protection measure helps to improve the reliability and safety of the entire granulation device.

[0035] Refer to Figure 1 、 Figure 3 、 Figure 4 , the thermoelectric cooler 605 is electrically connected to the power supply 607 through a wire 606. The thermoelectric cooler 605 is adhered to the blade body 601 through a viscous thermal conductive silicone grease sheet. The direct electrical connection through the wire 606 to the power supply ensures that the thermoelectric cooler 605 can receive a stable and continuous power supply, which provides the necessary energy guarantee for the normal operation of the cooler, enabling it to continuously provide a cooling effect for the blade body 601. At the same time, through the adhesion of the viscous thermal conductive silicone grease sheet to the blade body 601, efficient heat conduction between the cooler and the blade is achieved. This connection method not only ensures that the cooling effect can be evenly transmitted to the blade but also effectively reduces the thermal resistance and improves the cooling efficiency, helping to keep the blade in a low-temperature state, preventing raw material adhesion, and thus improving the granulation quality and efficiency.

[0036] Refer to Figure 1 、 Figure 3 、 Figure 4, the three groups of blade bodies 601 are arranged in an equidistant circular pattern along the central axis of the sleeve 608. The sleeve 608 is detachably connected to the transmission shaft 502. The equidistant circular arrangement of the blade bodies 601 ensures the uniformity and consistency during the granulation process. When the three groups of blades rotate, they can evenly scrape the raw materials, making the produced granules of uniform size and improving the product quality. At the same time, the detachable connection design between the sleeve 608 and the transmission shaft 502 facilitates the maintenance and replacement of the blades. When the blades are worn or damaged, the sleeve can be easily disassembled for replacement, reducing the maintenance cost and improving the maintainability and service life of the equipment.

[0037] Embodiment Three:

[0038] Refer to Figure 3 、 Figure 4 , on the other side of the surface of the blade body 601, there is a guiding piece 602 for guiding the raw materials. The guiding piece 602 can effectively guide the flow direction of the raw materials, ensuring that the raw materials can accurately enter the working area of the scraping mechanism 6. This improves the granulation accuracy and efficiency, avoiding the waste of raw materials. At the same time, the guiding piece 602 can also reduce the splashing and scattering of the raw materials during the scraping process to a certain extent, keeping the working environment clean. This is not only beneficial to the health and safety of the operators but also simplifies the subsequent cleaning work. Therefore, the setting of the guiding piece 602 improves the granulation quality while optimizing the working environment.

[0039] Refer to Figure 1 、 Figure 2 , on the top of the device main body 1, there is a spiral feeding cylinder 201. On one side of the spiral feeding cylinder 201, there is a first motor 203. On the other side of the spiral feeding cylinder 201, there is a discharge orifice plate 4. On the top of the spiral feeding cylinder 201, there is a funnel 202. On one side of the first motor 203, there is an electric control box 3. The spiral feeding cylinder 201 can effectively transport the raw materials from the funnel 202 to the discharge orifice plate 4 evenly and continuously, ensuring the continuity and stability of the granulation process. The first motor 203 provides power for the spiral feeding cylinder 201, further guaranteeing the conveying efficiency. At the same time, the discharge orifice plate 4 can control the discharge amount and speed of the raw materials to meet different granulation requirements. The electric control box 3 facilitates the operators to centrally control and monitor the entire device, improving the operability and safety of the equipment. The overall design is compact and reasonable, making the granulation process more efficient and convenient.

[0040] The implementation principle of the present utility model is as follows: Place the raw materials into the interior of the funnel 202. Subsequently, use the spiral blades inside the spiral feeding cylinder 201 to extrude and transport the raw materials until they are extruded from the discharge orifice plate 4 on one side. Then, use the second motor 501 to drive the blade body 601 to scrape the extruded raw materials to complete the granulation operation. During the scraping process, as the three groups of blade bodies 601 rotate, the semiconductor refrigeration sheet 605 on one side conducts cold air to the surface of the blade body 601, which is beneficial to gradually reducing the temperature of the surface of the blade body 601, thereby avoiding the situation of raw material adhesion caused by the overheating of the blade body 601. Among them, the air guide plate 604 is beneficial to adjusting the wind direction and accelerating the air flow rate on the surface of the semiconductor refrigeration sheet 605, avoiding the accumulation of heat on the heating surface of the semiconductor refrigeration sheet 605. The presence of the guide piece 602 is beneficial to avoiding the situation of raw material splashing caused by the presence of the air guide plate 604 and providing good guidance for the raw materials.

[0041] Parts not involved in the present utility model are the same as or can be implemented using the prior art, and will not be elaborated here.

[0042] Although the embodiments of the present utility model have been shown and described, the specific embodiments are only explanations of the present utility model and do not limit the utility model. The specific features, structures, materials or characteristics described can be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art can make modifications, substitutions and variations without creative contributions to the embodiments as needed, but as long as they are within the scope of the claims of the present utility model, they are protected by the patent law.
