Technical Field
[0001] The utility model relates to the technical field of reactors, in particular to a polycarboxylate water-reducing agent reactor with a cleaning function. Background Art
[0002] Polycarboxylate superplasticizer is a high-performance water reducer and a cement dispersant used in cement concrete. It has the advantages of low dosage, good slump retention, low concrete shrinkage, strong adjustability in molecular structure, and great potential for high performance. It is widely used in projects such as roads, bridges, dams, tunnels, and high-rise buildings. This product is green and environmentally friendly, non-flammable and non-explosive, and can be safely transported by train and car. To meet the process requirements for the production of polycarboxylate superplasticizer, clean polycarboxylate superplasticizer reactors are now mostly used.
[0003] In existing polycarboxylate superplasticizer cleaning reactors, a lot of polycarboxylate superplasticizer will adhere to the stirring blades during the stirring process. However, existing polycarboxylate superplasticizer cleaning reactors usually only focus on cleaning the inner wall of the reactor and ignore the cleaning of the stirring blades. In addition, the external water source is usually reconnected during cleaning, which increases the use of water resources. Utility Model Content

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions:
[0006] A polycarboxylate water-reducing agent reactor with a cleaning function comprises a reactor body, a reactor cover, a cooling shell, a stirring assembly and a cleaning assembly, wherein the top flange of the reactor body is connected to the reactor cover, the reactor cover is provided with a feed port, the bottom of the reactor body is provided with a discharge port, a stirring assembly is provided in the middle of the reactor cover, the stirring end of the stirring assembly extends into the inner side of the reactor body, the outer side of the reactor body is covered with a cooling shell, a closed cooling chamber for filling coolant is formed between the cooling shell and the reactor body, a water inlet and a water outlet are provided on the cooling shell, and the water inlet and the water outlet are both connected to an external water supply device, the input end of the cleaning assembly is located inside the cooling chamber, and the output end is located inside the reactor cover;
[0007] The cleaning assembly includes a water pump, a first water pipe, a second water pipe and an annular water pipe. The water pump is provided on the outside of the cooling shell. The input end of the water pump is connected to the side of the cooling chamber close to the water inlet. The output end of the water pump is respectively provided with a first water pipe and a second water pipe. The output ends of the first water pipe and the second water pipe extend from the top of the kettle cover to the inside of the kettle cover and are used to spray water into the kettle body. The output end of the first water pipe is provided with an annular water pipe.
[0008] Furthermore, the cooling liquid is clean water, and the water pump is used to extract the clean water in the cooling chamber to clean the inner side of the kettle body.
[0009] Furthermore, the stirring assembly includes a stirring motor, a stirring blade and a brush. The stirring motor is provided on the top of the kettle cover, and the output end of the stirring motor is provided with a stirring blade extending to the inner side of the kettle body. Two brushes are vertically symmetrically provided on the main axis of the stirring blade, and the bristles of the brush are in contact with the inner wall of the kettle body.
[0010] Furthermore, a plurality of nozzles are evenly distributed on the annular water pipe, the angle between the nozzles and the axis of the annular water pipe is degrees, and the number of nozzles is 8-12, and the nozzles face the inner wall of the kettle.
[0011] Furthermore, the output end of the second water pipe is inclined toward the main axis direction of the stirring assembly, and the second water pipe is used to clean the stirring assembly.
[0012] Compared with the prior art, the present invention has the following advantages after adopting the above technical solution:
[0013] This utility model utilizes a cleaning assembly that uses the coolant within the cooling chamber as a cleaning water source, not only fully flushing the inner wall of the reactor, but also effectively cleaning the stirring assembly through a specially designed second water pipe. This design addresses the problem of traditional reactors focusing solely on cleaning the inner wall while neglecting the stirring blades, thereby improving overall cleaning effectiveness. The cleaning assembly in this embodiment cleverly utilizes the coolant within the cooling shell for cleaning, eliminating the need to reconnect to an external water source and thus reducing water usage. The brushes attached to the stirring blades automatically clean the inner wall of the reactor as the stirring motor rotates, further enhancing cleaning effectiveness. Furthermore, the second water pipe is angled toward the main shaft of the stirring assembly, ensuring that the stirring blades and main shaft are also adequately flushed.
