[0033] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0034] Refer to Figure 1 , an embodiment provided by the present invention: a chemical reactor, including a reaction barrel 1, the top of the reaction barrel 1 is detachably installed with a cover body 2, the cover body 2 is detachably installed by support bolts, the top of the cover body 2 is fixedly connected with a three-phase asynchronous motor 3, and the bottom of the three-phase asynchronous motor 3 is provided with a cleaning mechanism 4; the cleaning mechanism 4 is driven to rotate by the three-phase asynchronous motor 3, so as to clean the inner wall of the reaction barrel 1.

[0035] Refer to Figures 2 - 4, the cleaning mechanism 4 includes a driving gear 406. A rotating shaft 401 is rotatably connected to the inner wall of the cover body 2, and the cleaning purpose is achieved by rotating the rotating shaft 401. A driven gear 405 is fixedly connected to the outer arc surface of the rotating shaft 401, and their movement trajectories are the same. A bidirectional threaded rod 407 is rotatably connected to the inner wall of the rotating shaft 401. A slider 410 is threadedly connected to the outer wall of the bidirectional threaded rod 407. A handle is provided at the top of the bidirectional threaded rod 407. By driving the bidirectional threaded rod 407 to rotate with the handle, the purpose of contraction is achieved. A three-stage telescopic plate 408 is fixedly connected to the outer wall of the slider 410. The three-stage telescopic plate 408 is composed of three horizontal plates of different sizes, and its overall length can be adjusted. Connecting plates 402 are rotatably connected to the left and right ends of the slider 410. A connecting plate 402 is rotatably connected to the left end of the connecting plate 402. A scraping plate 404 is triangular in shape. The triangular shape is convenient for the dirt after cleaning to flow down along the inclined surface. By moving the slider 410 up and down, the connecting plate 402 is driven to rotate, so that the two scraping plates 404 move horizontally. A bottom plate 409 is fixedly connected to the bottom end of the scraping plate 404. There are two groups of bottom plates 409, and the two groups are arranged staggeredly. The staggered arrangement avoids movement interference after the scraping plate 404 moves. A guide rod 411 is fixedly connected to the outer arc surface of the rotating shaft 401, and the guide rod 411 plays a guiding role. A discharge port 6 is fixedly connected to the top of the cover body 2. The discharge port 6 is used for feeding and discharging. A discharge mechanism 5 is provided at the top of the cover body 2.

[0036] Refer to Figures 3 - 5, the inner wall of the driving gear 406 is fixedly connected to the output end of the three-phase asynchronous motor 3. Through the three-phase asynchronous motor 3, the driving gear 406 is driven to rotate. The output end of the three-phase asynchronous motor 3 is rotatably connected to the inner wall of the cover body 2, and the rotation of the two avoids movement interference. The right end of the driven gear 405 meshes with the left end of the driving gear 406, and the meshing of the two causes the driving gear 406 to drive the driven gear 405 to rotate. The outer wall of the rotating shaft 401 is fixedly connected with a stirring rod 403, and the stirring rod 403 can perform stirring operations. The outer wall of the slider 410 is slidably connected to the inner wall of the rotating shaft 401. Chute grooves are provided on both the left and right sides of the rotating shaft 401, and the chute grooves play a guiding role for the slider 410, so that the slider 410 can only move in the vertical direction. The top end of the three-stage telescopic plate 408 is fixedly connected to the inner wall of the rotating shaft 401. A sealing gasket is provided around the three-stage telescopic plate 408 to play a sealing role. The setting of the three-stage telescopic plate 408 can further prevent dirt and liquid from entering the inside of the chute groove. The bottom end of the bottom plate 409 is in sliding contact with the bottom inner wall of the reaction barrel 1, and the contact between the two cleans the bottom inner wall of the reaction barrel 1. The outer wall of the scraper 404 is in contact with the inner wall of the reaction barrel 1, and the contact between the two scrapes the inner side wall of the reaction barrel 1. The left end of the guiding rod 411 is fixedly connected to the right end of the scraper 404, and the guiding rod 411 is an overall telescopic rod, which plays a guiding role for the scraper 404.

[0037] Referring to Figure 1 and Figure 6 , the discharging mechanism 5 includes a fixed seat 503. The top inner wall of the fixed seat 503 is slidably and rotatably connected with a fixed column 505. The fixed seat 503 plays a role in connecting and accommodating the fixed column 505. A baffle 504 is fixedly connected to the left end of the fixed column 505, and a sieve plate 506 is fixedly connected to the right end of the fixed column 505. The baffle 504 and the sieve plate 506 are of the same size and are adapted to the inner wall size of the discharging port 6. The purpose of screening can be achieved through the sieve plate 506. A bolt 507 is threadedly connected to the inner wall of the fixed seat 503, and the rear end of the bolt 507 is threadedly connected to the front end of the fixed column 505. Through the setting of the bolt 507, the fixed column 505 can be fixed and limited. A support seat 501 is provided at the bottom end of the reaction barrel 1, and a driving motor 502 is fixedly connected to the top end of the support seat 501. The output end of the driving motor 502 is fixedly connected to the left end of the reaction barrel 1. Through the rotation of the output end of the driving motor 502, the reaction barrel 1 is driven to rotate, so that the discharging port 6 faces downward. The bottom end of the fixed seat 503 is fixedly connected to the top end of the cover body 2, and the cover body 2 can support the fixed seat 503. The bottom ends of the sieve plate 506 and the baffle 504 can be inserted into the top inner wall of the discharging port 6. When the baffle 504 is inserted into the discharging port 6, the discharging port 6 is blocked at this time. When the sieve plate 506 is inserted into the discharging port 6, the unreacted raw materials can continue to react at this time, and the reacted ones can be discharged.

[0038] Working principle: Start the three-phase asynchronous motor 3, the output end of which drives the driving gear 406 to rotate. The driving gear 406 meshes with the driven gear 405, so that the driven gear 405 rotates, and then drives the rotating shaft 401 fixedly connected thereto to rotate on the inner wall of the cover body 2. The stirring rod 403 fixed on the outer arc surface of the rotating shaft 401 stirs the materials in the reaction barrel 1. When it is necessary to clean the inner wall of the reaction barrel 1, the bidirectional threaded rod 407 rotatably connected to the inner wall of the rotating shaft 401 is rotated by the handle at its top. The rotation of the bidirectional threaded rod 407 causes the slidable block 410 connected by threads to slide up and down on the inner wall of the rotating shaft 401. Since the outer wall of the slidable block 410 is slidably connected to the inner wall of the rotating shaft 401, and the chutes opened on the left and right sides of the rotating shaft 401 play a guiding role for the slidable block 410 to ensure that the slidable block 410 only moves in the vertical direction. When the slidable block 410 moves up and down, it drives the connecting plates 402 rotatably connected to its left and right ends to rotate, so that the two groups of scraping plates 404 move horizontally, and the outer walls of the scraping plates 404 contact the inner wall of the reaction barrel 1. Then start the three-phase asynchronous motor 3 to scrape the inner side wall of the reaction barrel 1. At the same time, when the slidable block 410 moves, the three-stage telescopic plate 408 will move, so as to prevent dirt from entering the inner wall of the rotating shaft 401.

[0039] When discharging is required, rotate the bolt 507 to release the limit on the fixed column 505, then move it upward and rotate the fixed column 505 by 180 degrees, so that the sieve plate 506 is inserted into the discharge port 6, and then rotate the bolt 507 in the reverse direction to achieve the fixing effect. Then start the driving motor 502 to make the reaction barrel 1 rotate. The reacted raw materials can be discharged through the sieve plate 506, and the unreacted ones continue to react.

[0040] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
