The feeding and discharging mechanism 2 is fixedly connected to both ends of the reaction vessel 1, and the feeding and discharging mechanism 2 includes a feeding component 21 and a discharging component 22. The following section will explain the specific setup and function of its feeding and discharging mechanism 2, mixing mechanism 3, and temperature control mechanism 4.

[0019] In this embodiment: the feeding assembly 21 includes a feeding filter screen 211 and a sealing gasket 212. The feeding filter screen 211 is snapped into the inside of the feeding assembly 21, and the sealing gasket 212 is snapped into the outer surface of the reactor 1.

Feed filter screens 211 are snapped into the inside of the feed hoppers 214. Feed filter screens 211 and feed hoppers 214 are symmetrically arranged on both sides of the top cover 5.

[0020] The effects achieved by the above components are as follows: the feed filter 211 can efficiently intercept various impurities in the raw materials, ensuring that the raw materials entering the reactor 1 to participate in the reaction have high purity and reducing the interference of impurities on the chemical reaction; the sealing gasket 212 fits tightly at the connection between the reactor 1 and the feed assembly 21, effectively preventing raw material leakage during the feeding process, avoiding material waste and environmental pollution, and at the same time isolating outside air from entering the reactor, maintaining the specific environment required for the reaction.

[0021] Specifically, the discharge assembly 22 is fixedly connected to the inside of the bottom cover 6. The discharge assembly 22 includes a connecting fixing plate 221 fixedly connected to the inside of the bottom cover 6. A discharge filter screen 222 is fixedly connected inside the connecting fixing plate 221. A discharge port 223 is opened at the bottom of the bottom cover 6. A sealing cover 224 is threadedly connected inside the discharge port 223.

[0022] The effects achieved by the above components are as follows: the discharge filter screen 222 can perform secondary fine filtration on the reaction products, effectively removing residual unreacted solid particles, impurities, etc., further improving the purity of the products and making the final products more in line with quality standards; the sealing cap 224 can tightly seal the discharge port 223 during the reaction process to prevent material leakage; when the reaction is completed and the products meet the discharge conditions, the operator can easily open the sealing cap 224 to carry out the discharge operation; and the material of the sealing cap 224 has excellent corrosion resistance and wear resistance.

[0023] Specifically, the stirring mechanism 3 includes a support plate 31 fixedly connected to the top of the upper cover 5, a servo motor 32 fixedly connected inside the support plate 31, and a connecting plate 33 fixedly connected to the output end of the servo motor 32.

[0024] The effects achieved by the above components are as follows: the support plate 31 provides a sturdy and stable mounting platform for key components such as the servo motor 32 in the stirring mechanism 3, and can withstand the vibration and torque generated by the servo motor 32 during high-speed operation, ensuring the stability of the stirring mechanism 3 during operation, and avoiding the impact of component shaking on the stirring effect or even damage to the equipment. The connecting plate 33 ensures that the power can be transmitted stably and efficiently, and ensures that the rotating stirring shaft 34 rotates accurately with the operation of the servo motor 32.

[0025] Specifically, a rotating stirring shaft 34 is threadedly connected to the bottom of the connecting plate 33, and bolts 35 are threadedly connected to both sides of the rotating stirring shaft 34. The rotating stirring shaft 34 is threadedly connected to the bottom of the connecting plate 33 through the bolts 35, and a spiral rotating plate 36 is fixedly connected to the outer surface of the rotating stirring shaft 34.

[0026] The effect achieved by the above components is that when the stirring shaft 34 rotates, the spiral rotating plate 36 can stir the materials in the reactor 1 in all directions and thoroughly, which promotes rapid mixing and uniform dispersion of the materials, and greatly improves the mixing efficiency and reaction rate of the materials.

[0027] Specifically, connecting columns 37 are fixedly connected to both ends of the rotating stirring shaft 34, a cleaning scraper 38 is fixedly connected to the far end of the connecting column 37, and a bearing 39 is rotatably connected to the bottom of the rotating stirring shaft 34. The outer surface of the bearing 39 is fitted into the top of the connecting fixing plate 221.

[0028] The effect achieved by the above components is as follows: when the stirring shaft 34 rotates, the connecting column 37 drives the cleaning scraper 38 to rotate synchronously. The cleaning scraper 38 can effectively scrape off the reaction residues attached to the reactor wall during the rotation process, keep the reactor wall clean, avoid the accumulation of residues affecting the heat transfer efficiency between the material and the reactor wall in subsequent reactions, and prevent the residues from breeding bacteria, microorganisms, etc., which would pollute the reaction environment.

[0029] Specifically, the temperature control mechanism 4 includes a spiral circulating water pipe 41 fixedly connected to the outer surface of the reactor 1. One end of the spiral circulating water pipe 41 is fixedly connected to a water inlet 42, and the other end of the spiral circulating water pipe 41 is fixedly connected to a water outlet 43.

[0030] The effect achieved by the above components is as follows: the spiral circulating water pipe 41 is installed around the outer surface of the reactor 1 and is made of metal pipe with good thermal conductivity. Its unique spiral structure design enables the fluid in the circulating water pipe to exchange heat with the reactor 1 more evenly, providing the most suitable temperature environment for the chemical reaction and ensuring that the reaction proceeds in the expected rate and direction.

[0031] Specifically, the inlet 42 and the outlet 43 are fitted with sealing caps 44. The inlet 42 is located at the top of the spiral circulating water pipe 41, and the outlet 43 is located at the bottom of the spiral circulating water pipe 41.

[0032] The effects achieved by the above components are as follows: the sealing cover 44 can effectively prevent dust, impurities and other foreign objects from entering the spiral circulating water pipe 41, avoid pipe blockage and affect the temperature control effect. When using the temperature control mechanism 4, the sealing cover 44 ensures the sealing of the connection between the inlet 42 and the outlet 43 and the spiral circulating water pipe 41, prevents water leakage, and ensures the normal operation of the circulating water system.

[0033] Working principle: When using this reactor for chemical synthesis reaction, the raw materials are first poured in through the feed funnel 214. When the raw materials pass through the feed filter screen 211, the impurities are intercepted. The pure raw materials enter the reactor 1 through the feed pipe 213. The sealing gasket 212 ensures that there is no leakage during the feeding process and maintains the specific environment inside the reactor.

[0034] The servo motor 32 is turned on, which drives the connecting plate 33 to rotate, thereby causing the rotating stirring shaft 34 to rotate. The spiral rotating plate 36 stirs and mixes the materials, while the cleaning scraper 38 rotates with the rotating stirring shaft 34 to clean the inner wall of the reactor.

[0035] The temperature control mechanism 4 starts working, and circulating water at a specific temperature is introduced into the spiral circulating water pipe 41 through the water inlet 42. The circulating water flows in the spiral circulating water pipe 41 and exchanges heat with the reactor 1 to regulate the temperature inside the reactor. The circulating water flows out from the water outlet 43. After the reaction is completed, the sealing cover 224 of the discharge port 223 is opened, and the product is discharged from the discharge port 223 after secondary filtration through the discharge filter screen 222, thus completing the entire chemical synthesis reaction process.
