Figure 1-5 , the technical scheme of the embodiment of the utility model is clearly and completely described. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the described embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the utility model.
[0026] like Figure 1-5As shown: This embodiment provides a chemical reactor, including a reactor 100 and a water tank 101. The upper surface of the reactor 100 is provided with a feed port 105, and personnel can add materials from the feed port 105 so that the materials enter the reactor 100. The bottom of the reactor 100 is provided with a discharge port 104, and the discharge port 104 is convenient for discharging the finished materials. The reactor 100 is provided with a stirring mechanism 200, and the stirring mechanism 200 includes a first rotating shaft, a second rotating shaft 201 and a stirring scraper. The bottom of the reactor 100 is provided with a stirring mechanism 200. A first rotating shaft is provided, and the bottom of the reactor 100 provides support for the first rotating shaft. A second rotating shaft 201 is provided at the top of the reactor 100, and the top of the reactor 100 provides support for the second rotating shaft 201. Stirring scrapers are provided on both sides of the second rotating shaft 201, and the stirring scrapers are fixed on the rotating shaft by welding. The stirring scrapers will continuously scrape off the materials attached to the inner wall of the reactor 100 to prevent the materials from accumulating on the wall, thereby ensuring the continuity and uniformity of the reaction. The first rotating shaft and one end of the second rotating shaft 201 are provided with the first rotating shaft in the steering mechanism 300. A differential gear 301, a first rotating shaft and a second rotating shaft 201 fix the first differential gear 301, so that the use of the steering mechanism 300 can change the rotation direction of the first rotating shaft and the second rotating shaft 201, and at the same time make the stirring uniform. The upper surface of the reactor 100 is provided with an annular groove 107, and an annular pipe 106 is provided in the groove 107. The bottom of the annular pipe 106 is provided with a plurality of water holes 108. The side end of the water tank 101 is provided with a water inlet pipe 110, and the water inlet pipe 110 is provided in cooperation with the annular pipe 106. The water tank 1 01 is supplied to the water inlet pipe 110, so that the water in the water inlet pipe 110 flows into the annular pipe 106, and the multiple water flow holes 108 in the annular pipe 106 discharge the water to the inner wall of the reactor 100, so that the inner wall of the reactor 100 can be cleaned and flushed. The mounting piece 402 in the fixing component 400 is arranged in the groove 107, and the mounting piece 402 is arranged in cooperation with the annular pipe 106 in the groove 107. The mounting piece 402 can fix the annular pipe 106, thereby preventing the annular pipe 106 from falling from the groove 107;
[0027] First, the required reactants are added into the reactor 100 through the feed port 105 at the top of the reactor 100, and then the reactants in the reactor 100 are stirred by the operation of the stirring mechanism 200. Due to the setting of the steering mechanism 300 in the stirring mechanism 200, the rotation directions of the first rotating shaft and the second rotating shaft 201 are opposite, so that the reactants are evenly stirred in the stirring mechanism 200, and then the materials are discharged from the discharge port. At this time, some materials remain on the inner wall of the reactor 100, and then the water pump in the water tank 101 draws water into the water inlet pipe 110 and discharges it into the annular pipe 106. Because there are multiple water flow holes 108 at the bottom of the annular pipe 106, the water in the annular pipe 106 can flow down along the inner wall of the reactor 100, and then the stirring scraper continues to rotate, and then the inner wall of the reactor 100 can be cleaned.
[0028] Stirring mechanism 200 Figure 5 As shown,
[0029] The stirring mechanism 200 includes a first stirring rod 204 and a second stirring rod 203. The first stirring rod 204 is arranged on the first rotating shaft and is fixed to the first rotating shaft by welding. The second stirring rod 203 is arranged on one side of the stirring scraper and is fixed to the stirring scraper by welding. The first stirring rod 204 and the second stirring rod 203 are staggered to avoid collision between the first stirring rod 204 and the second stirring rod 203, so that the material is stirred more evenly.
[0030] The steering mechanism 300 includes a first differential gear 301, a second differential gear 303 and a protective shell 304. The protective shell 304 is arranged between the ends of the first rotating shaft and the second rotating shaft 201. The protective shell 304 is fixed on the first rotating shaft and the second rotating shaft 201, so that the first rotating shaft and the second rotating shaft 201 can rotate in the protective shell 304. The protective shell 304 plays a connecting role. The first differential gear 301 is arranged at the ends of the first rotating shaft and the second rotating shaft 201. The first differential gear 301 is fixed on the first rotating shaft and the second rotating shaft 201. The second differential gear 303 is arranged on both sides of the protective shell 304 through the ends of the rotating column 302. The first differential gear 301 is meshed with the second differential gear 303. When the second rotating shaft 201 rotates clockwise, the first differential gear 301 is driven to rotate. Due to the action of the second differential gear 303, the other first differential gear 301 drives the first rotating shaft to rotate counterclockwise.
[0031] The second shaft 201 rotates clockwise to drive the first differential gear 301 to rotate. Due to the action of the second differential gear 303, the first shaft rotates counterclockwise. Then the stirring scraper on the second shaft 201 rotates clockwise to drive the second stirring rod 203, so that the first stirring rod 204 on the first shaft rotates accordingly. As a result, the second stirring rod 203 and the first stirring rod 204 have different rotation directions, so that the material is more uniform.
