Description

Technical Field

[0001] This utility model belongs to the field of materials science and technology, specifically a compatibilizer processing rapid heating device. Background Technology

[0002] The processing of compatibilizers usually requires mixing with the substrate in a molten state to achieve chemical reactions or physical dispersion between molecular chains. Traditional heating methods have a slow heating rate, and it takes a long time for the material to reach the target processing temperature, resulting in a longer overall processing cycle. Rapid heating devices can quickly heat the material to the set temperature through efficient heat conduction, which greatly shortens the preheating time and thus increases the output per unit time. They are especially suitable for online heating links in continuous production.

[0003] The principle of the compatibilizer processing rapid heating device mainly involves two aspects: conductive heat transfer and resistance heating. By applying the precise principles of conductive heat transfer and resistance heating, the compatibilizer processing rapid heating device can efficiently achieve compatibility of materials that need to be processed, providing strong support for the production of materials that require processing.

[0004] In existing compatibilizer processing devices, when heating and melting compatibilizers, the melted compatibilizer adheres to the inner wall of the heating device, forming a residual compatibilizer layer that acts as a heat barrier. This causes the heat generated by the external heating mechanism to be indirectly transferred to the compatibilizer inside through the residual layer, resulting in a significant decrease in heat transfer efficiency and uneven melting. Therefore, a rapid heating device for compatibilizer processing is proposed to address these issues. Utility Model Content

[0005] To overcome the shortcomings of existing technologies and address the problems of existing equipment, this utility model proposes a compatibilizer processing rapid heating device.

[0006] The technical solution adopted by this utility model to solve its technical problem is a compatibilizer processing rapid heating device, including a tank. A top cover is rotatably installed on the top of the tank. An electric valve is fixedly installed inside the bottom of the tank. A discharge pipe is fixedly installed inside the electric valve. A rotating shaft is installed at the center of the bottom of the inner wall of the tank. A drive rod is fixedly installed on the rotating shaft. Multiple stirring rods are fixedly installed on the outer side of the drive rod. The outer sides of the multiple stirring rods are provided with multiple irregular serrations. Connecting plates are fixedly installed on both sides of the rotating shaft and the drive rod. A rotating plate is fixedly installed on the outer side of one end of the connecting plate. A scraper is fixedly installed on the side of one end of the multiple rotating plates, and a wear-resistant material is fixedly installed on the side of the scraper. The high-temperature rubber pad, the rotating plate, and the scraper are all tightly fitted with baffles. The bottom of the baffle is fixedly installed on the bottom of the inner wall of the tank, and an electric heating wire is installed in the gap between the baffle and the tank. The stirring rod and the scraper are driven by a drive motor to rotate. When the materials to be mixed are mixed during the stirring process, the material adhering to the side of the baffle is cleaned by the scraper driven by the rotating plate, so that it cannot continue to adhere to the side of the baffle and hinder the heat transfer of the electric heating wire to the inside of the baffle. This accelerates the mixing between the materials. In addition, the high-temperature resistant rubber pad fixed to the side of the scraper has good elasticity, so that the side of the scraper and the side of the baffle are tightly fitted, ensuring more thorough scraping of the adhering material, reducing residue, accelerating heat transfer, and improving mixing efficiency.

[0007] Preferably, a mounting base is fixedly installed at the center of the inner wall of the top cover, one end of the drive rod is externally rotatably installed inside the mounting base, a fixing plate is fixedly installed on the inner wall of the top cover, a slot is opened between the fixing plates, and a sealing gasket is fixedly installed on both sides of the slot. Multiple sealing gaskets are respectively tightly attached to both sides of the baffle, and are connected to the mounting base with sealing gaskets inside the baffle, effectively filling the gap between the baffle and the mounting base, blocking the gas flow path, directly improving the airtightness of the tank, and increasing the residence time of high-temperature gas inside the tank.

[0008] Preferably, a support frame is fixedly installed at the bottom of the tank, and a drive motor is fixedly installed inside the support frame. A drive bevel gear is installed at the output end of the drive motor, and a driven bevel gear is meshed with the outside of the drive bevel gear. The rotating shaft passes through the inside of the tank and is fixedly installed inside the driven bevel gear. The drive motor drives the drive bevel gear to rotate. When the drive bevel gear rotates, it drives the driven bevel gear to rotate. When the driven bevel gear rotates, it drives the rotating shaft to rotate. The rotation of the rotating shaft drives the drive rod and the scraper to rotate.

[0009] Preferably, a pressure relief valve is fixedly installed on the top of the top cover. The detection end of the pressure relief valve passes through the inside of the top cover and is located inside the tank. The pressure relief valve detects the air pressure inside the tank. When the air pressure inside the tank is too high, the pressure relief valve will release the air pressure inside the tank to balance the air pressure inside the tank.

[0010] Preferably, support legs are fixedly installed at all four ends of the bottom of the tank, and anti-slip pads are fixedly installed at the bottom of each of the support legs. The anti-slip pads are made of rubber. The large friction of the rubber anti-slip pads can significantly enhance the tightness of the support legs in contact with the ground, effectively preventing the tank from sliding or shifting due to vibration or external force during operation.

[0011] Preferably, the drive motor, electric valve, pressure relief valve, and electric heating wire are all electrically connected to an external control panel. The control panel is used to start and stop them. With the control panel, it is not necessary to operate multiple components independently. A single control panel can achieve centralized control of the heating device and related components, simplifying the operation process and reducing the complexity of manual intervention.

[0012] The advantages of this utility model are:

[0013] This invention uses a drive motor to rotate the stirring rod and scraper. When the materials to be mixed are mixed during the stirring process, the material adhering to the side of the baffle is cleaned by the scraper driven by the rotating plate, preventing it from sticking to the side of the baffle and hindering the heat transfer from the heating wire to the inside of the baffle. This accelerates the mixing of the materials. Furthermore, the high-temperature resistant rubber pad fixed to the side of the scraper has good elasticity, ensuring that the side of the scraper fits tightly against the side of the baffle, ensuring more thorough removal of the adhering material, reducing residue, accelerating heat transfer, and improving mixing efficiency.

Baffles 3 are tightly attached to the outer sides of the rotating plates 9 and the scrapers 10. The bottom of the baffle 3 is fixedly installed on the bottom of the inner wall of the tank 1, and an electric heating wire 24 is provided in the gap formed between the baffle 3 and the tank 1. During operation, in order to more efficiently make the compatible materials compatible, the stirring rod 7 and the scraper 10 are driven by the drive motor 13 to rotate. When the materials to be compatible are mixed during the stirring process, the material adhering to the side of the baffle 3 will be cleaned by the scraper 10 driven by the rotating plate 9, so that it cannot continue to adhere to the side of the baffle 3 and hinder the heat transfer of the electric heating wire 24 to the inside of the baffle 3, thereby accelerating the mixing between the compatible materials. In addition, the high-temperature resistant rubber pad 11 fixed to the side of the scraper 10 has good elasticity, so that the side of the scraper 10 and the side of the baffle 3 are tightly attached, ensuring that the adhering material is scraped more thoroughly, reducing residue, and achieving the effect of accelerating heat transfer and improving mixing efficiency.

[0023] A mounting base 21 is fixedly installed in the center of the inner wall of the top cover 2. One end of the drive rod 5 is externally rotatably installed inside the mounting base 21. A fixing plate 20 is fixedly installed in the inner wall of the top cover 2. A slot is opened between the fixing plates 20, and a sealing gasket 22 is fixedly installed on both sides of the slot. Multiple sealing gaskets 22 are respectively tightly attached to both sides of the baffle 3. During operation, in order to improve the airtightness of the tank 1 and retain the temperature inside the tank 1 for a longer period of time, the baffle 3 is connected to the mounting base 21 with sealing gaskets 22 inside, which effectively fills the gap between the baffle 3 and the mounting base 21, blocks the gas flow path, directly improves the airtightness of the tank 1, and increases the residence time of the high temperature gas inside the tank 1.

[0024] A support frame 12 is fixedly installed at the bottom of the tank body 1. A drive motor 13 is fixedly installed inside the support frame 12. A drive bevel gear 14 is installed at the output end of the drive motor 13. A driven bevel gear 15 is meshed with the outside of the drive bevel gear 14. The rotating shaft of the rotating shaft 4 passes through the inside of the tank body 1 and is fixedly installed inside the driven bevel gear 15. During operation, in order to drive the scraper 10 to clean the compatibilizer on the side of the baffle 3, the drive motor 13 drives the drive bevel gear 14 to rotate. When the drive bevel gear 14 rotates, it drives the driven bevel gear 15 to rotate. When the driven bevel gear 15 rotates, it drives the rotating shaft of the rotating shaft 4 to rotate. The rotation of the rotating shaft of the rotating shaft 4 drives the drive rod 5 and the scraper 10 to rotate.

[0025] A pressure relief valve 23 is fixedly installed on the top of the top cover 2. The detection end of the pressure relief valve 23 passes through the inside of the top cover 2 and is located inside the tank body 1. During operation, in order to prevent the device from being damaged due to excessive air pressure inside the tank body 1, the air pressure inside the tank body 1 is detected through the detection end of the pressure relief valve 23. When the air pressure inside the tank body 1 is too high, the pressure relief valve 23 will release the air pressure inside the tank body 1 to balance the air pressure inside the tank body 1.

[0026] Support legs 18 are fixedly installed at all four ends of the bottom of the tank body 1. Anti-slip pads 19 are fixedly installed at the bottom of the multiple support legs 18. The anti-slip pads 19 are made of rubber. During operation, in order to make the device more stable during use, the large friction of the rubber anti-slip pads 19 can significantly enhance the tightness of the support legs 18 with the ground, effectively preventing the tank body 1 from sliding or shifting due to vibration, external force contact, etc. during operation.

[0027] The drive motor 13, electric valve 16, pressure relief valve 23, and electric heating wire 24 are all electrically connected to an external control panel, which is used to control their start and stop. During operation, in order to more conveniently control the start and stop of the heating device, the control panel eliminates the need to operate multiple components independently. A single control panel can achieve centralized control of the heating device and related components, simplifying the operation process and reducing the complexity of manual intervention.

[0028] Working principle: In existing compatibilizer processing devices, when heating and melting the compatibilizer, the melted compatibilizer adheres to the inner wall of the heating device, forming a residual compatibilizer layer that acts as a heat barrier. This forces the heat from the external heating mechanism to be indirectly transferred to the compatibilizer inside through the residual layer, resulting in a significant decrease in heat transfer efficiency and uneven melting. To solve this problem, the top cover 2 is first opened, and the compatibilizer is placed between the PP and PA materials to be compatible. Then, the top cover 2 is closed, and the electric heating wire 24 is activated to melt the materials to be compatible with the compatibilizer. During the melting process, the drive motor 13 is activated, driving the active bevel gear 14 to rotate. When the active bevel gear 14 rotates, it drives the driven bevel gear 15 to rotate. When the driven bevel gear 15 rotates, it drives the rotating shaft 4 to rotate. The rotation of the rotating shaft 4 drives the drive rod 5. When the drive rod 5 rotates, it drives the multiple stirring rods 7 on both sides to stir the materials to be mixed. During the stirring process, the multiple irregular serrations 8 on the outside of the stirring rods 7 form a strong shearing force through the local high speed gradient at the tip of the serrations, which directly breaks up the micron-sized agglomerates and accelerates the melting of the materials to be mixed. When the materials to be mixed are mixed during the stirring process, the material adhering to the side of the baffle 3 is cleaned by the scraper 10 driven by the rotating plate 9, so that it cannot continue to adhere to the side of the baffle 3 and obstruct the heat transfer from the heating wire 24 to the inside of the baffle 3. This accelerates the mixing between the materials to be mixed. Furthermore, the high-temperature resistant rubber pad 11 fixed to the side of the scraper 10 has good elasticity, which makes the side of the scraper 10 fit tightly against the side of the baffle 3, ensuring more thorough scraping of the adhering material, reducing residue, and achieving the effect of accelerating heat transfer and improving mixing efficiency.
