DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0029] See also Figure 1-Figure 5 The present application provides a sodium hydroxide preparation tank, including a preparation tank 10, a heating component 20 and a cooling component 30.

[0030] Among them, the preparation tank 10 can mix the preparation of sodium hydroxide, the heating component 20 can heat the mixed solution to make the sodium hydroxide dissolve more quickly, and the cooling component 30 can quickly cool the mixed and heated sodium hydroxide solution to increase the solution cooling time.

[0031] See also Figure 1 、 Figure 2 、 Figure 4 and Figure 5 The preparation tank 10 includes an anti-corrosion tank body 110, a stirring member 120 is provided inside the anti-corrosion tank body 110, a feed port 130 and a liquid inlet pipe 140 are respectively provided on the anti-corrosion tank body 110, and a liquid outlet pipe 150 is provided at the bottom of the anti-corrosion tank body 110; wherein, when it is necessary to prepare a sodium hydroxide solution, the solubility of the solution to be prepared is first calculated, and then the required weight of sodium hydroxide and volume of water are calculated. After the calculation is completed, the sodium hydroxide is added to the interior of the anti-corrosion tank body 110 through the feed port 130, and then the required water is added to the interior of the anti-corrosion tank body 110 through the liquid inlet pipe 140, and the stirring member 120 is started to mix and stir them. After the mixing is completed, the solution is discharged through the liquid outlet pipe 150. The anti-corrosion setting of the anti-corrosion tank body 110 can prevent the tank body from being corroded by sodium hydroxide, thereby improving the service life of the tank body.

[0032] In this embodiment, a flow meter 160 and a solenoid valve 170 are sequentially mounted on the liquid inlet pipe 140 and electrically connected to each other. The required amount of water is first set using the flow meter 160. Then, the solenoid valve 170 is activated to allow water to flow through the liquid inlet pipe 140 into the interior of the corrosion-resistant tank 110 for mixing. Once the water volume reaches the desired level, the solenoid valve 170 automatically closes. The coordination of the flow meter 160 and the solenoid valve 170 allows for more accurate water volume measurement, eliminating the need for manual weighing.

[0033] In this embodiment, the stirring member 120 includes a driving member 121, which is mounted on the top of the anti-corrosion tank body 110. The driving member 121 is connected to a stirring rod 122. The bottom end of the stirring rod 122 movably penetrates the top wall of the anti-corrosion tank body 110 and extends into the interior of the anti-corrosion tank body 110. A stirring blade 123 is mounted on the stirring rod 122. A bracket 180 is fixedly connected to the top of the anti-corrosion tank body 110, and the driving member 121 is mounted on the bracket 180. The driving member 121 includes a motor 1211, which is mounted on the side of the bracket 180. The output end of the motor 1211 is fixedly connected to a driving pulley 1212, and a driven pulley 1213 is rotatably connected to the bracket 180. A transmission belt 1214 is connected to the outside of the driving pulley 1212 and the driven pulley 1213. The top of the stirring rod 122 is fixedly connected to the driven pulley 1213. When the inside of the anti-corrosion tank body 110 needs to be stirred, the motor 1211 is started, and the motor 1211 drives the active pulley 1212 to rotate. Further, under the action of the transmission belt 1214, the driven pulley 1213 is rotated, and finally the stirring rod 122 is rotated, thereby realizing the rotation of the stirring blade 123 to stir the solution and improve the mixing effect.

[0034] Specifically, a blocking cap is provided on the feed port 130. After the sodium hydroxide is added, the blocking cap covers the feed port 130 to prevent the solution from spilling out of the feed port 130 during stirring and mixing.

[0035] See also Figure 1 、 Figure 2 and Figure 3 The heating assembly 20 includes a bottom shell 210, which is located at the bottom of the anti-corrosion tank body 110, and the inner wall of the bottom shell 210 and the outer wall of the bottom of the anti-corrosion tank body 110 form a first cavity 230. The inner wall of the bottom shell 210 is installed with a heating device 220 in a circular array and is located inside the first cavity 230. Specifically, the heating device 220 can be an electric heating wire or an electric heater; wherein, when the sodium hydroxide cannot be completely dissolved under the stirring of the stirring member 120, the heating device 220 is started to heat the anti-corrosion tank body 110, which can accelerate the dissolution rate of the sodium hydroxide. After the dissolution is completed, the heating device 220 can be turned off. By setting the heating device 220, the mixture can be easily heated, the dissolution rate of the sodium hydroxide can be increased, and the preparation efficiency can be improved.

[0036] See also Figure 1 and Figure 2 The cooling end of the cooling component 30 is arranged outside the anti-corrosion tank 110 and is connected to the top of the bottom shell 210. After the sodium hydroxide solution is prepared, the solution needs to be cooled. The cooling component 30 can speed up the cooling speed of the solution.

[0037] In this embodiment, the cooling assembly 30 includes a housing 310 and a water circulation component 330. The housing 310 is located outside the corrosion-resistant tank 110 and is connected to the top of the bottom shell 210. The inner wall of the housing 310 and the outer wall of the corrosion-resistant tank 110 form a second cavity 320, and the water circulation component 330 is connected to the second cavity 320. The water circulation component 330 includes a water tank 331. Specifically, the water tank 331 is provided with a water inlet and a sewage outlet. A circulation pump 332 is installed at the top of the water tank 331. The water inlet of the circulation pump 332 is connected to a connecting pipe 335, the other end of which is connected to the interior of the water tank 331. The water outlet of the circulation pump 332 is connected to a water outlet pipe 333, the other end of which is connected to the bottom of the second cavity 320. A return pipe 334 is connected to the top of the second cavity 320, and the other end of the return pipe 334 is connected to the water tank 331. When the solution needs to be cooled after preparation, the circulation pump 332 is started, and the water inside the water tank 331 is pumped out through the connecting pipe 335 and enters the second cavity 320 through the outlet pipe 333. When the water inside the second cavity 320 is full, the excess water enters the water tank 331 through the return pipe 334. In this way, the solution inside the anti-corrosion tank 110 is quickly physically cooled through water circulation, thereby accelerating the cooling speed of the solution.

[0038] The working principle of this sodium hydroxide preparation tank is as follows: when preparing sodium hydroxide solution, the solubility of the solution is first calculated, and then the weight of sodium hydroxide and the volume of water required are calculated. After the calculation is completed, the sodium hydroxide is added to the interior of the corrosion-resistant tank body 110 through the feed port 130. Then, the required water is added to the interior of the corrosion-resistant tank body 110 through the liquid inlet pipe 140. The stirring member 120 is started to mix and stir. After mixing, the solution is discharged through the liquid outlet pipe 150. The corrosion-resistant setting of the corrosion-resistant tank body 110 can prevent the tank body from being corroded by sodium hydroxide, thereby increasing the service life of the tank body. When the sodium hydroxide cannot be completely dissolved under the stirring of the stirring member 120, the heating device 220 is started to heat the corrosion-resistant tank body 110, which can accelerate the dissolution rate of the sodium hydroxide. After the dissolution is completed, the heating device 220 is turned off. The setting of the heating device 220 can facilitate heating and increase the dissolution rate of the sodium hydroxide, thereby improving the preparation efficiency. After the sodium hydroxide solution is prepared, it is necessary to cool the solution. The cooling assembly 30 can accelerate the cooling rate of the solution.
