[0025] See also Figure 1-3 , the utility model provides a technical solution:

[0026] A polycarboxylic acid high-performance water-reducing agent production control device includes a floor 1 and a reactor body 4. A weighing plate 2 is fixedly connected to the top of the floor 1, and the reactor body 4 is fixedly connected to the top of the weighing plate 2. A stirring device 10 is inserted into the center of the top of the reactor body 4. The stirring device 10 and the reactor body 4 are sealed. A feeding pipe 14 is provided at the bottom center of the reactor body 4. The other end of the feeding pipe 14 is connected to the storage tank through a feeding pump.

A hot air blower 21 is fixedly connected to one end of the surface of the air injection pipe 20, and the other end of the air injection pipe 20 is connected to the hot air blower 21. An air inlet pipe 22 extends from the bottom of the hot air blower 21, and the other end of the air inlet pipe 22 is connected to the fan 5. A wall 3 is provided in the vertical direction of the ground 1, and the fan 5 is arranged on the wall 3;

[0027] A feeding tank 15 is provided on the top of the ground 1 and outside the weighing plate 2. A feeding pipe 27 is provided at the top center of the feeding tank 15. The other end of the feeding pipe 27 is connected to the surface of the reactor body 4.

[0028] A control device 19 is fixedly connected to the rear end of the surface of the reactor body 4 , and a temperature sensor 30 is fixedly connected to the back of the control device 19 . The temperature sensor 30 is located inside the reactor body 4 .

[0029] Furthermore, a solenoid valve 9 is provided on the surface of the feed pipe 8 .

[0030] Furthermore, the gas injection pipe 20 is connected to the air inlet pipe 22 through a connecting air pipe 25. A first gas mass flow controller 23 is arranged below the connection between the air inlet pipe 22 and the connecting air pipe 25, and a second gas mass flow controller 26 is arranged on the inner side of the connection between the connecting air pipe 25 and the air inlet pipe 22 and the connecting air pipe 25.

[0031] Furthermore, a first one-way valve 24 is provided below the first gas mass flow controller 23 , and a second one-way valve 28 is provided above the connection between the gas injection pipe 20 and the hot air blower 21 .

[0032] Furthermore, a water pump 13 and a liquid flow machine 12 are sequentially provided on the surface of the water injection pipe 11 from the outside to the inside.

[0033] Furthermore, a feeding pipe 16 is provided on the surface of the feeding tank 15 .

[0034] Furthermore, a feeding tank 15 is provided between the outer side of the weighing plate 2 and the feeding tank 15 and is connected to the feeding main pipe 27 through a feeding pipe 29. A feeding pump 17 is provided at the connection between the feeding pipe 29 and the feeding tank 15, and a check valve 18 is provided on the top of the feeding pump 17.

[0035] Specifically, the weighing plate 2 is electrically connected to the control device 19 , and the weighing plate 2 displays the weighed weight on the surface display screen of the control device 19 . Workers can accurately weigh the solid raw materials and water through the weight on the display screen.

[0036] Working principle: When in use, first add solid raw materials into the hopper 7, where the weight data on the display screen of the control device 19 is the added weight. When it rises to the appropriate data, stop injecting the solid raw materials, and then open the solenoid valve 9 to allow the solid raw materials to enter the interior of the reactor body 4 from the hopper 7 through the feed pipe 8.

[0037] Then, water is injected into the water injection pipe 11, which is connected to the water source through a connecting water pipe. Then, the water pump 13 is started. The water pump 13 will pump water from the water source. The liquid flow meter 12 will measure the flow rate in the water injection pipe 11 in real time. When the flow rate exceeds the requirement, the power of the water pump 13 can be appropriately reduced. When the amount of increase in the control device 19 reaches the requirement, the water pump 13 is turned off.

[0038] Then the reaction can be carried out through the reactor body 4. During the reaction process, materials need to be added to the reactor body 4, where the materials are located in different feeding tanks 15. After one of the materials needs to be added to the reactor body 4, the feeding pump 17 on the top of the feeding tank 15 storing this material is turned on by the control device 19, and the material in the feeding tank 15 is extracted into the interior of the reactor body 4 through the feeding main pipe 27.

[0039] During the feeding process, the material will be pumped up by the feeding pump 17 and will enter the feeding main pipe 27 from the feeding pipe 29. In order to allow the material in the subsequent feeding tank 15 to come to the feeding pipe 29 of another feeding tank, the material will be placed into the feeding tank 15 of another material through the check valve 18.

[0040] In addition, after the material in the feeding tank 15 is reduced, the material in the feeding tank 15 can be replenished by adding material into the feeding pipe 16.

[0041] During the reaction, the temperature sensor 30 will measure the temperature in real time and display it on the control device 19. Sometimes it is necessary to increase the temperature in the reactor body 4. Specifically, the fan 5 and the hot air blower 21 are turned on first. The fan 5 will collect natural wind and introduce it into the air inlet pipe 22. The first gas mass flow controller 23 and the second gas mass flow controller 26 will control the gas flow through the control device 19. Specifically, when the flow in the first gas mass flow controller 23 is large, most of the gas will flow into the hot air blower 21, and the hot air blower 21 will heat the wind. When the flow in the second gas mass flow controller 26 is large, the gas will flow into the hot air blower 21. When the amount is large, a large amount of wind will directly enter the gas injection pipe 20 from the connecting gas pipe 25. The control device 19 can control the flow of the first gas mass flow controller 23 and the second gas mass flow controller 26 to inject hot air that meets the temperature into the reactor body 4. In addition, at the beginning of the reaction, the second gas mass flow controller 26 can be completely closed and the first gas mass flow controller 23 can be completely opened to quickly heat up the reactor body 4. Conversely, after the reaction is completed, the second gas mass flow controller 26 can be completely closed and the first gas mass flow controller 23 can be completely closed to cool down the reactor body 4.

[0042] In addition, during the gas flow process, it will pass through the first one-way valve 24 and the second one-way valve 28, wherein the first one-way valve 24 will allow the air to flow from top to bottom, and the second one-way valve 28 will allow the air to move from bottom to top, preventing gas turbulence.

[0043] Because the reactor body 4 needs to be frequently injected with gas, the internal pressure of the reactor body 4 may be too high. The internal pressure of the reactor body 4 will be measured in real time by a pressure gauge 6. When the internal pressure is too high, the staff will open the pressure relief valve to control the discharge of excess gas.

[0044] After the reaction is completed, the feed pump is turned on to transport the final material to the next process through the feed pipe 14.

[0045] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
