DETAILED DESCRIPTION

[0021] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, a polycarboxylate water-reducing agent reactor proposed in the utility model comprises a reactor body 1, a movable top cover 2 is arranged above the reactor body 1, a stirring motor 3 is penetrated on the upper part of the movable top cover 2, a stirring shaft 4 is fixedly connected to the output end of the stirring motor 3, a stirring blade 5 is fixedly connected to the stirring shaft 4, and a cleaning equipment frame 6 is fixedly connected to the stirring shaft 4, a slot 7 is provided on the cleaning equipment frame 6, a cleaning scraper 8 is inserted into the slot 7; a limiting bayonet 9 is fixedly connected to the slot 7, a limiting slide groove 10 is provided on the cleaning scraper 8, and the limiting slide groove 10 is slidably arranged on the limiting bayonet 9.

[0022] The lower parts of both sides of the cleaning equipment frame 6 are fixedly connected with a limit housing 11 , and a pull rod 12 is slidably provided on the limit housing 11 , and a limit rod 13 which is arranged to penetrate the cleaning scraper 8 is fixedly connected to the pull rod 12 .

[0023] The limiting slot 10 can be limited by sliding through the limiting bayonet 9, and then the limiting rod 13 can be used to fix the limiting slot 10, which can improve the stability and the efficiency during maintenance and replacement.

[0024] A limit retaining ring 14 is fixedly connected to the pull rod 12 and penetrates the limit housing 11. The limit retaining ring 14 is arranged between the pull rod 12 and the limit rod 13. A tightening spring 15 is sleeved on the pull rod 12. A self-cleaning rubber gasket 16 is arranged on the upper part of the reactor body 1. The inner diameter of the self-cleaning rubber gasket 16 is smaller than the inner diameter of the reactor body 1.

[0025] It should be noted that the self-cleaning rubber gasket 16 is made of rubber material and has a certain elasticity, which can avoid causing obstacles to the cleaning scraper 8 during the upward movement and ensure the contact with the cleaning scraper 8 to achieve a self-cleaning effect.

[0026] A mounting support is fixedly connected to the lower part of the reactor body 1 , and a lifting cylinder 17 is fixedly connected to the mounting support. The output end of the lifting cylinder 17 is fixedly connected to the lower part of the movable top cover 2 .

[0027] The lifting cylinder 17 can be controlled to work, the output end can be extended, and the movable top cover 2 can be pushed to drive the structure thereon to move upward, which can achieve self-cleaning and facilitate installation and maintenance.

[0028] When used specifically, the user prepares the polycarboxylate water-reducing agent in the reactor body 1, controls the stirring motor 3 to drive the stirring shaft 4 to work, and makes the stirring blade 5 rotate and stir inside the reactor body 1 to make the mixing reaction uniform;

[0029] The cleaning equipment frame 6 rotates with the stirring shaft 4, so that the cleaning scraper 8 scrapes the inner wall of the reactor body 1 to prevent the polycarboxylate water-reducing agent raw material from adhering to the inner wall and remaining thereon. The synchronous stirring structure is used to avoid the trouble of separate cleaning.

[0030] When the lifting cylinder 17 is working, the rise of the movable top cover 2 drives the cleaning scraper 8 to cooperate with the self-cleaning rubber gasket 16 for self-cleaning. After the rise, the limit rod 13 can be moved out of the cleaning scraper 8 by pulling the pull rod 12 to release the limit. At this time, the cleaning scraper 8 can be slid downward on the slot 7 for removal, which is convenient for replacement;

[0031] When installing the cleaning scraper 8, the cleaning scraper 8 is slidably installed on the slot 7, the limiting slide groove 10 slides on the limiting bayonet 9, and after the pull rod 12 is released, the elastic potential energy of the tightening spring 15 pushes the limiting retaining ring 14, and the limiting rod 13 is inserted into the cleaning scraper 8 to be fixed, so as to achieve quick installation;

[0032] The above is the entire use process of a polycarboxylate water reducer reactor.

[0033] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
