[0020] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0021] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0022] Embodiment 1, as Figure 1-Figure 4As shown, the utility model provides a polymerization kettle with a cooling device for a polycarboxylic acid water-reducing agent, comprising a polymerization kettle body 1, a circulating cooling mechanism 3 is arranged on the outer surface of the polymerization kettle body 1, a stirring mechanism 4 is arranged on the top of the polymerization kettle body 1, the circulating cooling mechanism 3 comprises a water storage tank 301 and a temperature sensor 312, a water inlet 302 is fixedly connected to the top of the water storage tank 301, a threaded cover 303 is connected to the outer thread of the water inlet 302, a ventilation pipe 304 is arranged on the top of the water storage tank 301, a micro motor 305 is arranged on the inner surface wall of the ventilation pipe 304, a connecting rod 306 is fixedly connected to the output end of the micro motor 305, a plurality of rotating blades 307 are arranged and fixedly connected to the outer surface of the connecting rod 306, and the temperature sensor 312 is arranged on the outer surface of the connecting rod 306. The outer surface of 12 is fixedly installed with the outer surface of the polymerization kettle body 1, the inner wall of the ventilation pipe 304 is provided with a dustproof net 308, the inner wall of the water tank 301 is fixedly connected with a circulation pipe 309, and the outer surface of the circulation pipe 309 is fixedly inserted into the interior of the water tank 301, and the outer surface of the circulation pipe 309 is connected with the interior of the polymerization kettle body 1, a water pump 310 is arranged on the outer surface of the circulation pipe 309, and a base 311 is arranged at the bottom of the water pump 310, and a plurality of support columns 2 are fixedly installed at the bottom of the polymerization kettle body 1 near the four corners, and the bottoms of the plurality of support columns 2 are fixedly connected with a bottom plate 21, the top of the bottom plate 21 is fixedly installed with the bottom of the water tank 301, and the top of the bottom plate 21 is fixedly connected with the top of the base 311.

[0023] The effect achieved by the entire embodiment 1 is that when using the device to cool the polymerization kettle, first, by rotating and opening the threaded cover 303, add an appropriate amount of water to the water tank 301 through the water inlet 302. At this time, the temperature sensor 312 will monitor the temperature inside the polymerization kettle body 1 in real time. When the temperature reaches or exceeds the preset value, the temperature sensor 312 will send a signal to the external controller, and the water pump 310 will be started by the external controller to extract the water stored in the water tank 301 and guide it to the inside of the polymerization kettle body 1 through the circulation pipe 309. Inside the polymerization kettle, the flowing water serves as a cooling medium to effectively absorb and take away the heat generated during the reaction of the raw materials, thereby achieving the purpose of cooling. After the cooling is completed, the water continues to flow along the path of the circulation pipe 309, and finally returns to the water tank 301 again, forming a circulating cooling. When the water pump 310 is turned on to cool the polymerization kettle body 1, the circulation pipe 309 will The heat generated by the reaction of the raw materials in the polymerization kettle is brought into the water tank 301. During this process, the water inside the water tank 301 will absorb the heat, causing its temperature to gradually increase. As the cycle continues, the water in the water tank 301 will accumulate a certain amount of heat. At this time, the micro motor 305 is started, and its output end drives the connecting rod 306 to rotate. During the rotation of the connecting rod 306, the rotating blade 307 can rotate at a high speed to dissipate the water inside the water tank 301, thereby increasing the contact time between the water in the water tank and the air, and accelerating the heat dissipation efficiency of the water in the water tank. The dustproof net 308 can effectively prevent dust from entering from the ventilation pipe 304. Under the action of the circulating cooling mechanism 3, the polymerization kettle after the reaction is completed can be cooled, avoiding the traditional natural cooling method, thereby shortening the time required for cooling, which not only ensures the production cycle but also improves work efficiency. The support column 2 mainly fixes the polymerization kettle body 1.

[0024] Embodiment 2, as Figure 1-Figure 4 As shown, the stirring mechanism 4 includes a driving motor 401, which is installed on the top of the polymerization kettle body 1. The output end of the driving motor 401 passes through the top of the polymerization kettle body 1 and extends to the bottom. The output end of the driving motor 401 is fixedly connected to a rotating rod 402, and a plurality of stirring blades 403 are arranged and fixedly connected on the outer surface of the rotating rod 402.

[0025] The effect achieved by the entire embodiment 2 is that when the device is used to cool the polymerization kettle, the driving motor 401 is started and its output end drives the rotating rod 402 to rotate. During the rotation of the rotating rod 402, the stirring blade 403 can be driven to rotate, thereby stirring the raw materials in the polymerization kettle, so that the cooling can be more uniform. Under the action of the stirring mechanism 4, the raw materials can be prevented from being locally overheated or overcooled during the cooling process, ensuring that the temperature distribution in the entire polymerization kettle is more uniform, and avoiding problems that may be caused by temperature differences.

[0026] Working principle: When in use, first open the threaded cover 303 and add water to the water storage tank 301. At this time, the temperature sensor 312 will monitor the temperature of the polymerization kettle. When the temperature reaches or exceeds the preset value, the temperature sensor 312 will send a signal to the external controller, which will start the water pump 310 to extract the water and guide it to the inside of the polymerization kettle body 1 through the circulation pipe 309. The flowing water absorbs and takes away the heat of the raw materials as a cooling medium to achieve the purpose of cooling. The water continues to flow along the circulation pipe 309 and finally returns to the water storage tank 301 again, and the drive is started. The motor 401 is driven to drive the rotating rod 402 to rotate. During the rotation of the rotating rod 402, the stirring blade 403 can be driven to rotate to stir the raw materials in the polymerization kettle, so that the cooling can be more uniform. When the water pump 310 is turned on to cool the polymerization kettle, the circulation pipe 309 will bring the heat in the polymerization kettle into the water tank 301, causing its temperature to gradually increase. At this time, the micro motor 305 is started to drive the connecting rod 306 to rotate. During the rotation of the connecting rod 306, the rotating blade 307 can rotate at a high speed to dissipate the water inside the water tank 301.

Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields.
