[0002] A reactor is a container for physical or chemical reactions. Through the structural design and parameter configuration of the container, the heating, evaporation, cooling and low-speed mixing functions required by the process are realized. It is widely used in petroleum, chemical, rubber, pesticide, dye, medicine, and food. It is a pressure vessel for completing processes such as vulcanization, nitration, hydrogenation, hydrocarbonization, polymerization, and condensation.

[0003] After searching, the Chinese patent announcement number CN219984686U discloses a safe chemical reactor, which relates to the technical field of chemical reactors. The patent discloses a feeding pipe on the top of the outer surface of the tank body, a motor on the top of the tank body, a stirring rod rotatably connected to the inner wall of the tank body, one end of the stirring rod is fixedly connected to the output end of the motor, and the bottom of the stirring rod is arranged on an auxiliary cleaning device. The auxiliary cleaning device includes a U-shaped scraper. The device can clean the U-shaped scraper and the stirring rod by inserting the hexagonal block into the hexagonal through hole and the inner wall of the auxiliary block under the action of the hexagonal block. The rod is fixed, and the motor is started at this time. The motor will drive the U-shaped scraper connected to the stirring rod to rotate synchronously on the inner wall of the tank. The scraper will scrape off the substances attached to the inner wall of the tank during the rotation, which can effectively prevent these substances from becoming impurities in the next reaction and ensure the normal use of the reactor. However, in actual production, for chemical production with multi-step reactions, since it is necessary to produce intermediate products before the next step of reaction, multiple feedings are required. In the prior art, multiple feedings are required, temperature control is inconvenient, and accidents are easy to cause. The practicality needs to be enhanced. Utility Model Content

[0025] The utility model is further described below in conjunction with the accompanying drawings:

[0026] like Figure 1 — Figure 6As shown, a safety chemical reactor comprises a main body 1, a stirring mechanism 2 is installed in the main body 1, a connecting mechanism 3 is installed on the side of the main body 1, a pressure relief mechanism 4 is arranged on the connecting mechanism 3, the main body 1 comprises a shell 101, a first heating chamber 102 and a second heating chamber 104 are arranged inside the shell 101, two sets of independently controlled heating wires are arranged inside the shell 101, which are used to provide heat to the first heating chamber 102 and the second heating chamber 104 respectively, an insulation board 103 is arranged between the first heating chamber 102 and the second heating chamber 104, a feeding hopper 105 is welded on the top of the shell 101, and a discharge pipe 106 is connected to the bottom of the shell 101 by bolts. When the device is in use, the main reaction occurs in the second heating chamber 104. When the reaction in the second heating chamber 104 is sufficient, the raw materials for the secondary reaction can be transported from the first heating chamber 102 to the second heating chamber 104 through the connecting mechanism 3 to carry out the next chemical reaction.

[0027] In this embodiment, the stirring mechanism 2 includes a motor 201, which is connected to the top of the shell 101 by bolts. The output end of the motor 201 is connected to a stirring shaft 202. The stirring shaft 202 passes through the insulation board 103 and is arranged in the first heating chamber 102 and the second heating chamber 104. According to the raw materials in the first heating chamber 102 and the second heating chamber 104 are heated to different temperatures respectively, the motor 201 drives the stirring shaft 202 to stir the raw materials in the first heating chamber 102 and the second heating chamber 104 to make the reaction more complete.

[0028] In this embodiment, the connecting mechanism 3 includes a first connecting tube 301, the top of the first connecting tube 301 is at the bottom of the first heating chamber 102, a connecting box 302 is welded to the bottom of the first connecting tube 301, a second connecting tube 303 is welded to the bottom side of the connecting box 302, the bottom end of the second connecting tube 303 is connected to the top of the second heating chamber 104, a first sealing gasket 307 cooperates with the first connecting tube 301, the connecting box 302, a damping shaft 304 is rotatably connected in the connecting box 302, and one end of the damping shaft 304 is connected to a rotating block by bolts. 305, a conversion block 306 is welded on the side of the damping shaft 304, and a first sealing gasket 307 and a second sealing gasket 308 are glued on opposite sides of the conversion block 306. When the reaction is in progress, the first sealing gasket 307 is located at the bottom of the first connecting tube 301. At this time, the second heating chamber 104 and the first heating chamber 102 are separated from each other and heated separately. When it is necessary to add the raw materials in the first heating chamber 102 into the second heating chamber 104, the first sealing gasket 307 is separated from the bottom of the first connecting tube 301 to mix the two parts of the raw materials.

[0029] In this embodiment, the pressure relief mechanism 4 includes a pressure relief pipe 401, which is welded to the side of the connecting box 302 and connected to the inside of the connecting box 302. A plurality of pressure relief holes 402 are arranged on the side of the pressure relief pipe 401. The pressure relief pipe 401 cooperates with the second sealing gasket 308. One end of the pressure relief pipe 401 is connected to a sealing cover 403 by bolts. A screw rod 404 is threadedly connected to the sealing cover 403. One end of the screw rod 404 is rotatably connected to a movable plate 405. The movable plate 405 is slidably connected to the inside of the pressure relief pipe 401. A spring 406 is fixedly installed on one side of the movable plate 405. The other end of the spring 406 is fixedly connected to a pressure plate 407. Rotating the screw rod 404 can change the position of the movable plate 405, thereby adjusting the distance between the pressure plate 407 and the pressure relief hole 402, so as to relieve pressure in response to different requirements, and has a high safety factor.

[0030] Working principle: When the device is in use, the raw materials for the initial reaction are first preheated in the first heating chamber 102 and then passed into the second heating chamber 104. The main reaction occurs in the second heating chamber 104, and then the raw materials for the subsequent reaction are put into the first heating chamber 102. In this state, the first sealing gasket 307 is located at the bottom of the first connecting pipe 301, and the first heating chamber 102 and the second heating chamber 104 are in an isolated state. According to the raw materials in the first heating chamber 102 and the second heating chamber 104 are heated to different temperatures, the motor 201 drives the stirring shaft 202 to stir the raw materials in the first heating chamber 102 and the second heating chamber 104 to make the reaction more complete. When the reaction in the second heating chamber 104 is sufficient, the staff rotates the rotating block 305, and the rotating block 305 drives the damping shaft 304 to rotate, and the damping shaft 304 separates the first sealing gasket 307 from the bottom of the first connecting pipe 301 through the conversion block 306, and the second sealing gasket 308 rotates to the position of the pressure relief pipe 401. At this time, the first heating chamber 102 is connected with the second heating chamber 104, and the raw materials of the secondary reaction are transported from the first heating chamber 102 to the second heating chamber 104. Then, the conversion block 305 is rotated to separate the second sealing gasket 308 from the position of the pressure relief pipe 401, and the first sealing gasket 307 re-seals the bottom of the first connecting pipe 301, and the next chemical reaction is carried out in the second heating chamber 104. The high pressure generated by the reaction will push the pressure plate 407 in the pressure relief pipe 401. When the pressure reaches a certain level, the pressure plate 407 compresses the spring 406 until the pressure plate 407 moves to the position of the pressure relief hole 402, and the pressure is automatically relieved, which is highly safe.
