[0002] The polycarboxylate water-reducing agent reactor can increase the reaction speed of the raw materials and promote the uniformity of raw material mixing through the stirring mechanism in the reactor. After the polycarboxylate water-reducing agent obtained by the reaction is discharged from the reactor, sticky substances are usually attached to the inner wall of the reactor. There are two conventional treatment methods. One is simple cleaning: a high-pressure water gun is inserted through the feed port to clean the reactor, but due to the size of the feed port, the inside of the reactor cannot be completely cleaned; the other is more complicated and requires the lid of the reactor to be removed for cleaning separately, which is labor-intensive and time-consuming, affecting industrial efficiency. Utility Model Content

DETAILED DESCRIPTION

[0017] The utility model will be further described below in conjunction with the accompanying drawings.

[0018] like Figure 1 and Figure 2As shown, the polycarboxylate water-reducing agent reactor with a cleaning function comprises a reactor body 7, a supporting leg 10 is connected to the bottom of the reactor body 7, a discharge port 11 is centrally arranged at the bottom of the reactor body 7, a valve 12 is connected to the discharge port 11, a reactor cover 5 is connected above the reactor body 7, a feeding port 6 is arranged on the reactor cover 5, a hollow shaft tube 14 is rotatably connected to the center of the reactor cover 5, a driving mechanism for driving the hollow shaft tube 14 to rotate is connected above the reactor cover 5, a conduit 1 is rotatably connected to the top end of the hollow shaft tube 14, a water pump 19 is connected to the other end of the conduit 1, and a support plate 18 for supporting and placing the water pump 19 is arranged on the side wall of the reactor body 7;

[0019] The hollow shaft tube 14 extends into the kettle body 7, and stirring rods 17 are symmetrically connected on both sides. The end of the stirring rod 17 away from the hollow shaft tube 14 is threadedly connected to the adjusting rod 16, and a stirring driving blade 15 is arranged in the middle of the adjusting rod 16. The end of the adjusting rod 16 away from the hollow shaft tube 14 is rotatably connected to the scraper 13;

[0020] The helical angle of the thread on the stirring rod 17 will affect the thread driving effect of the adjusting rod 16 and the stirring rod 17. The larger the helical angle, the more conducive it is for the stirring driving blade 15 to drive the adjusting rod 16 to move on the stirring rod 17 by using the thread; the stirring driving blade 15 is provided with an angle, and the driving motor 4 drives the hollow shaft tube 14 to rotate in the forward direction, which will cause the stirring driving blade 15 to rotate and drive the adjusting rod 16 away from the hollow shaft tube 14; the driving motor 4 drives the hollow shaft tube 14 to rotate in the reverse direction, which will cause the stirring driving blade 15 to rotate in the reverse direction and drive the adjusting rod 16 close to the hollow shaft tube 14;

[0021] A cleaning pipe 8 is connected to the hollow shaft tube 14 , the interior of the cleaning pipe 8 is communicated with the hollow shaft tube 14 , and a plurality of nozzles 9 with different spray angles are arranged on the surface of the cleaning pipe 8 , so that the kettle body 7 can be fully and comprehensively flushed with high pressure.

[0022] In order to stabilize the scraper 13, when the adjusting rod 16 moves to the outermost end, it can provide a cleaning scraping function for the kettle body 7. Furthermore, two groups of stirring rods 17 are provided, distributed at the upper and lower ends of the hollow shaft tube 14 located inside the kettle body 7, and the ends of the two groups of stirring rods 17 away from the hollow shaft tube 14 are jointly connected to the scraper 13.

[0023] In order to facilitate the discharge of materials and the cleaning of the inside of the kettle body 7, further, the bottom of the kettle body 7 is a funnel structure, and the scraper 13 matches the structure of the kettle body 7.

[0024] During the process of high-pressure cleaning of the inside of the kettle body 7 through the cleaning pipe 8, the cleaning pipe 8 itself cannot achieve a cleaning effect. In order to achieve a comprehensive cleaning effect, further, at least two groups of cleaning pipes 8 are provided, both of which are arranged between the two groups of stirring rods 17, and the nozzles 9 on adjacent cleaning pipes 8 are staggered, so that adjacent cleaning pipes 8 can clean each other.

[0026] When the utility model is actually used, raw materials are put into the feeding port 6, and the driving motor 4 is started to drive the hollow shaft tube 14 to rotate by engaging the driven gear plate 2 through the driving gear plate 3, and the hollow shaft tube 14 drives the stirring rod 17 and the cleaning tube 8 to rotate to stir the raw materials. During the stirring process, the stirring driving blade 15 rotates under the resistance of the raw materials, thereby driving the adjusting rod 16 away from the hollow shaft tube 14. By the forward and reverse rotation of the driving motor 4, the adjusting rod 16 can be reciprocated, thereby improving the stirring efficiency of the raw materials and achieving a full stirring effect.

[0027] After the stirring is completed and discharged through the discharge port 11, the water pump 19 is started to pump water from the water inlet end through the conduit 1 to the hollow shaft tube 14, then enter the cleaning pipe 8, and then be sprayed out from the nozzle 9. The driving motor 4 rotates forward at high speed to rotate the stirring driving blade 15 and drive the adjusting rod 16 away from the hollow shaft tube 14 so that the scraper 13 has a scraping effect on the inner wall of the kettle body 7, and cooperates with the high-pressure water flow sprayed from the nozzle 9 to achieve a comprehensive cleaning effect on the inside of the kettle body 7.
