Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-3 A reaction vessel for polymerizing polycarboxylate high-performance water-reducing agent includes a shell 1, a movable sealing plate 100 is provided on the top of the shell 1, the bottom of the sealing plate 100 is in contact with the top of the shell 1, a driving stirring assembly 2 is provided on the sealing plate 100, and an adjusting scraping assembly 3 is provided on the driving stirring assembly 2.

[0020] The sealing plate 100 has positioning grooves 4 on both the left and right sides of its bottom. A positioning block 5 is fixedly connected to the top of the housing 1 at the position corresponding to the positioning groove 4. The top of the positioning block 5 passes through the positioning groove 4 and extends into it to contact the inner wall of the positioning groove 4. By setting the positioning groove 4 and the positioning block 5, the stability of the sealing plate 100 placed on the housing 1 is improved. A heating plate 6 is fixedly connected to the right side of the inner wall of the housing 1.

[0021] The front of the housing 1 is movably connected to the feeding cover via a hinge, and the bottom of the housing 1 is fixedly connected to the discharge pipe that communicates with it. A valve is installed on the discharge pipe, and support legs are fixedly connected to the four corners of the bottom of the housing 1.

[0022] The driving stirring assembly 2 includes a stirring motor 21, which is mounted on the top of the sealing plate 100. A rotating shaft 22 is fixedly connected to the bottom end of the output shaft of the stirring motor 21. The bottom end of the rotating shaft 22 passes through the sealing plate 100 and the housing 1 from top to bottom and extends into the interior of the housing 1. Four stirring rods 23 are fixedly connected to both the left and right sides of the rotating shaft 22. Support blocks 24 are fixedly connected to both the left and right sides of the housing 1. An electric push rod 25 is fixedly connected to the top of the support block 24. A movable block 26 is fixedly connected to the top of the electric push rod 25. The movable block 26 is fixedly connected to the sealing plate 100 on the side closest to the sealing plate 100. The stirring motor 21, the electric push rod 25, and the heating plate 6 are electrically connected to an external controller.

[0023] The adjusting scraping assembly 3 includes two connecting blocks 31, which are respectively installed on the left and right sides of the rotating shaft 22. The connecting blocks 31 are fixedly connected to the rotating shaft 22 via sliding rods 32. A slider 33 is slidably connected to the surface of the sliding rod 32. An adjusting block 34 is fixedly connected to the bottom of the slider 33. A movable scraper 35 is provided on the surface of the stirring rod 23. The inner wall of the scraper 35 slides in contact with the surface of the stirring rod 23, so that the scraper 35 can scrape off the residue on the surface of the stirring rod 23. The four scrapers 35 on the same side are fixedly connected by three fixing blocks 36. The bottom of the adjusting block 34 is fixedly connected to the scraper 35 located at the top. A stabilizing block 37 is fixedly connected to the stirring rod 23 located at the top left side. An arc-shaped scraper 38 that works with the housing 1 is fixedly connected to the left side of the stabilizing block 37. The side of the arc-shaped scraper 38 closest to the inner wall of the housing 1 is in close contact with the inner wall of the housing 1, thereby facilitating the scraping off of the residue on the inner wall of the housing 1.

[0024] A movable block 39 is fixedly connected to the top of the slider 33. The side of the movable block 39 close to the connecting block 31 slides in contact with the connecting block 31. A fastening bolt 310 that is threadedly connected to the movable block 39 is provided on the top of the connecting block 31. By setting the movable block 39 and the fastening bolt 310, the slider 33 is limited, ensuring the stability of the scraper 35 on the stirring rod 23 when it is not in use.

[0025] Start the electric push rod 25, which drives the sealing plate 100 to move upward. The sealing plate 100 drives the rotating shaft 22 and the adjusting scraping assembly 3 to move upward, so that the connecting block 31 and the fastening bolt 310 move to the outside of the housing 1. Loosen the fastening bolt 310, and then pull the slider 33. The slider 33 moves away from the rotating shaft 22 on the surface of the slider 32. The slider 33 drives the scraper 35 to move on the surface of the stirring rod 23 through the adjusting block 34 and the fixing block 36, so that the scraper 35 can scrape off the residue on the surface of the stirring rod 23.

[0026] By setting up the driving stirring component 2, the polycarboxylate high-performance water-reducing agent material in the shell 1 can be stirred and reacted by the stirring rod 23. Moreover, the electric push rod 25 can pull the stirring structure out of the shell 1, which is convenient for maintenance and cleaning of the stirring structure and improves the flexibility of use. By setting up the adjusting scraping component 3, it is not only convenient to scrape off the residue on the inner wall of the shell 1, but also convenient to scrape off the residue on the stirring rod 23, avoiding waste of resources and improving the flexibility of use.

[0027] In use, open the feeding cover and sequentially add liquid raw materials such as polyether macromonomer, acrylic acid, and chain transfer agent. Close the feeding cover, and the heating plate 6 heats the inside of the shell 1. Start the stirring motor 21. The stirring motor 21 drives the rotating shaft 22 and the stirring rod 23 to rotate and stir the materials. At the same time, the stirring rod 23 drives the arc-shaped scraper 38 to scrape off the residue on the inner wall of the shell 1. After stirring is completed, open the valve on the discharge pipe to discharge the material. At this time, the stirring rod 23 continues to drive the arc-shaped scraper 38 to rotate and scrape off the residue on the inner wall of the shell 1.
