[0024] The present invention will be further described below with reference to the accompanying drawings:
[0025] like Figures 1-5As shown, a chemical production reactor includes a support column 103, a reactor body 101 welded to the top of the support column 103, a discharge pipe 106 connected to the bottom of the reactor body 101 via electrofusion, a temperature control mechanism 4 installed inside the reactor body 101, a reactor cover 102 fixedly connected to the top of the reactor body 101, multiple clamping mechanisms 2 equidistantly arranged around the bottom circumference of the reactor cover 102, a feed hopper 104 fixedly connected to the top of the reactor cover 102, an exhaust pipe 105 fixedly connected to the top of the reactor cover 102, a flushing water pipe 107 connected to the top of the reactor cover 102 via electrofusion, a feed control mechanism 3 installed at the bottom of the feed hopper 104, and a stirring mechanism 5 installed inside the reactor body 101. The stirring mechanism 5 includes a motor 501 connected via screws. At the top of the vessel lid 102, a spiral stirring blade 502 is welded to the output shaft of the motor 501. Multiple stirring rods 504 are welded to the output shaft of the motor 501. The stirring rods 504 are arranged in a spiral and equidistant manner. An arc block 505 is connected to the end of the stirring rod 504 away from the output shaft of the motor 501 by a screw. An arc-shaped scraper 503 is connected to the bottom of the output shaft of the motor 501 by a screw. The arc-shaped scraper 503 is symmetrically arranged and contacts the bottom of the vessel body 101. A rinsing mechanism 6 is provided on the output shaft of the motor 501. The motor 501 drives the arc-shaped scraper 503 to rotate. The arc-shaped scraper 503 rotates close to the bottom surface of the vessel body 101, which, together with the rotation of the spiral stirring blade 502, makes the upper and lower materials in the vessel body 101 evenly stirred.
[0026] The clamping mechanism 2 includes multiple limiting blocks 201. The limiting blocks 201 are threadedly connected to the bottom of the vessel cover 102. The limiting blocks 201 are threadedly connected to a threaded rod 202. A hexagonal nut 203 is fixedly connected to the top of the threaded rod 202.
[0027] The feeding control mechanism 3 includes a fixed block 301, which is welded to the top of the lid 102. The fixed block 301 is rotatably connected to a rotating blade 302, which extends into the bottom of the feeding hopper 104. When feeding, the rotating blade 302 is rotated clockwise to open the feeding hopper 104. After feeding, the rotating blade 302 is rotated counterclockwise to enter the feeding hopper 104 and close the feeding hopper 104.
[0028] The temperature control mechanism 4 includes an inlet pipe 401 and an outlet pipe 403. Both the inlet pipe 401 and the outlet pipe 403 are fixedly connected to the vessel body 101. The inlet pipe 401 is located below the outlet pipe 403. A spiral tube 402 is fixedly connected to the inlet pipe 401. The spiral tube 402 is arranged in a spiral upward state inside the wall of the vessel body 101. The inlet pipe 401 is located below the outlet pipe 403 in order to prolong the heat exchange time and make the heating more uniform.
[0029] The rinsing mechanism 6 includes a diversion bucket 601, which is connected to the output shaft of the motor 501 by screws. The diversion bucket 601 is connected to a water spray pipe 602 by threads. The diversion bucket 601 is located below the rinsing water pipe 107. The water flowing out of the rinsing water pipe 107 falls into the diversion bucket 601, and then the water is sprayed onto the inner wall of the vessel body 101 through the water spray pipe 602.
[0030] The discharge pipe 106 is connected to a solenoid valve 7 by screws.
[0031] A sealing strip 8 is fixedly connected to the top of the vessel body 101, and the sealing strip 8 is fixedly connected to the bottom of the vessel cover 102.
[0032] Working principle: During operation, the rotating blade 302 rotates clockwise. After feeding, the rotating blade 302 rotates counterclockwise, positioning it within the feed hopper 104. If heating is required, hot water enters through the inlet pipe 401. Subsequently, the motor 501 operates, driving the spiral stirring blade 502, the arc-shaped scraper 503, and the stirring rod 504 to rotate. The rotation of the spiral stirring blade 502 carries the material from below to the upper layer, ensuring a more complete reaction. The arc-shaped scraper 503, stirring rod 504, and arc-shaped block... Rotation 505 prevents materials from adhering to the inner wall of the reactor 101 for a long time. The gas generated during the reaction is discharged from the exhaust pipe 105. After the reaction is completed, the solenoid valve 7 is opened and the material is discharged from the discharge pipe 106. Then, the flushing water pipe 107 is connected. The water flows into the diversion hopper 601 and is sprayed out through the spray pipe 602, so that the water is sprayed inside the reactor 101. The rotating arc scraper 503 and arc block 505 scrape away the residual material and, together with the water flow, clean the inner wall of the reactor 101.
[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
