[0020] Please refer to Figures 1-3, an embodiment provided by the present utility model: a reaction crystallizer for the production of calcium sulfate whiskers, comprising a reaction tank 1, a reaction vessel 2 and a collection pump 4. The reaction vessel 2 is designed in a hemispherical shape. Two support ears 11 are symmetrically and fixedly connected to the top end of the reaction vessel 2. A support rod 12 is fixedly connected to the top end of the side of the support ear 11 away from the reaction vessel 2. Inside the reaction vessel 2, a scraper 13 is rotatably connected to the middle of the support ear 11. The scraper 13 is designed in a semi-circular shape, and the outer circular side of the scraper 13 matches the inside of the reaction vessel 2. When the scraper 13 rotates, it can scrape the items inside the reaction vessel 2 to quickly clean the reactants. A second servo motor 14 is fixedly installed in the middle of the side of one of the support ears 11 away from the reaction vessel 2. One end of the scraper 13 close to the second servo motor 14 passes through the reaction vessel 2 and is fixedly installed on the driving end of the second servo motor 14.

[0021] On the inner side of the top end of the reaction tank 1, two sliding grooves 3 are symmetrically opened. A top sliding cover 7 is slidably connected to the inside of the sliding groove 3. The top end of the reaction tank 1 is closed by the top sliding cover 7 to prevent the raw materials from splashing outside during the reaction. A push-pull rod 8 is fixedly connected to the rear end of the top sliding cover 7. A PLC controller 15 is fixedly installed on the top end of the top sliding cover 7. Electric push rods 9 are symmetrically and fixedly installed on both sides of the reaction tank 1. The telescopic ends of the two electric push rods 9 are respectively fixedly installed at both ends of the push-pull rod 8. The telescopic movement of the electric push rods 9 drives the top sliding cover 7 to move inside the sliding grooves 3 to realize the opening and closing operations. A first servo motor 10 is fixedly installed on one side of the reaction tank 1. A pumping plate 5 is fixedly connected to the front end of the collection pump 4. A handle 6 is fixedly connected to the middle of the end of the pumping plate 5 away from the collection pump 4.

[0022] The collection pump 4 is movably inserted into the inner bottom end of the reaction tank 1. The side of the pumping plate 5 close to the collection pump 4 is in contact connection with the front end of the reaction tank 1. The reaction vessel 2 is rotatably connected to the inside of the reaction tank 1 through the support rod 12. The reaction vessel 2 rotates and tilts inside the reaction tank 1 to facilitate pouring out the items inside the reaction vessel 2. One end of one of the support rods 12 away from the reaction vessel 2 is fixedly installed on the driving end of the first servo motor 10. By driving the support rod 12 to rotate through the driving end of the first servo motor 10, the reaction vessel 2 can be driven to rotate for pouring.

[0023] The PLC controller 15 is electrically connected to the electric push rod 9, the first servo motor 10 and the second servo motor 14 in a wired manner. The operation of the equipment is conveniently controlled through the PLC controller 15.

[0024] Working principle: During use, first set the control program through the PLC controller 15, then insert the collection pump 4 into the interior of the reaction box 1 through external force, control the electric push rod 9 to extend through the PLC controller 15, and the telescopic end of the electric push rod 9 pushes the push-pull rod 8 away from the reaction box 1, and the movement of the push-pull rod 8 drives the top slide cover 7 to slide on the inner side of the slide groove 3 away from the reaction box 1, and then pour the production raw materials into the interior of the reaction container 2 through external force, and then control the electric push rod 9 to retract through the PLC controller 15, and the telescopic end of the electric push rod 9 drives the top slide cover 7 to move completely to the top of the reaction box 1. When the reaction is completed, control the electric push rod 9 to extend through the PLC controller 15 to drive the top slide cover 7 to move and open, and then control the first servo motor 10 to start through the PLC controller 15, and the driving end of the first servo motor 10 drives the support rod 12 to rotate, and the rotation of the support rod 12 drives the support ear 11 to rotate, and the rotation of the support ear 11 drives the reaction container 2 to rotate ninety degrees. At this time, the reactants and The crystals fall into the interior of the collecting pump 4, and then the second servo motor 14 is started by the PLC controller 15. The driving end of the second servo motor 14 drives the scraper 13 to rotate downward, and the rotating scraper 13 scrapes off the objects adhered to the inner wall of the reaction container 2. The scraper 13 rotates downward from one side of the top of the reaction container 2, and the scraper 13 rotates 180 degrees to the other side of the top of the reaction container 2, and then rotates again to scrape off all the objects inside the reaction container 2. After scraping, the first servo motor 10 is controlled by the PLC controller 15 to start reversing, driving the reaction container 2 to return to the initial horizontal position, and then the second servo motor 14 is controlled to start and drive the scraper 13 to rotate to the horizontal position, and then the handle 6 is pulled away from the reaction box 1 by external force, and the movement of the handle 6 drives the pumping plate 5 to move, and the movement of the pumping plate 5 drives the collecting pump 4 to leave the interior of the reaction box 1 and transfer the reaction mixture and the crystals to the subsequent processing device for subsequent processing, and then the collecting pump 4 is inserted into the interior of the reaction box 1 to continue the reaction operation.
