Description

Technical Field

[0001] This utility model relates to the field of sodium hypochlorite preparation technology, and in particular to a sodium hypochlorite disinfectant preparation device. Background Technology

[0002] Sodium hypochlorite disinfectant is widely used in wastewater treatment, hospital disinfection, and industrial cleaning due to its strong oxidizing properties and significant disinfection effect. In the industrial field, sodium hypochlorite is mainly prepared by two methods: electrolysis and chlorine gas method. Since the chlorine gas method is cheaper than the electrolysis method, it is more commonly used in industry to prepare sodium hypochlorite disinfectant.

[0003] A search revealed that the document with publication number "CN215976067U" states that "This utility model discloses a sodium hypochlorite disinfectant preparation device, relating to the field of disinfectant preparation devices; this utility model includes a brine storage tank, a feed pipe, an electrolytic plate tank, a discharge pipe, a sodium hypochlorite storage tank, and a power supply; the brine storage tank is connected to the electrolytic plate tank via the feed pipe; the electrolytic plate tank is connected to the sodium hypochlorite storage tank via the discharge pipe; the power supply is connected to the electrolytic plate tank; the electrolytic plate tank is sealed and connected via a screw assembly; a feed spring assembly is provided at the connection between the screw assembly and the feed plate; a discharge spring assembly is provided at the connection between the screw assembly and the discharge plate." In use, by respectively placing the feed spring assembly and the discharge spring assembly at the connection between the insulated screw and the feed plate and the discharge plate, the leakage problem caused by frequent exothermic expansion and cooling contraction of the electrolytic plate tank during the electrolysis of brine is solved, ensuring the stability of the system operation and eliminating the safety hazards caused by leakage.

[0004] However, heat is generated during the reaction of chlorine gas and sodium hydroxide solution. If the heat generated by the reaction is not dealt with in time, the reaction will become too violent and difficult to control, affecting the yield and purity of sodium hypochlorite. At the same time, excessively high temperatures will promote the decomposition of sodium hypochlorite, reducing product quality and stability.

[0005] Therefore, we provide a sodium hypochlorite disinfectant preparation device to solve the above problems. Utility Model Content

[0006] To overcome the above deficiencies, this utility model provides a sodium hypochlorite disinfectant preparation device, which aims to solve the problems mentioned above.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A sodium hypochlorite disinfectant preparation device includes a mounting bracket, a reaction vessel welded to the inner side of the mounting bracket, a temperature control assembly inside the reaction vessel, a solution inlet pipe located on the left side of the reaction vessel, a sealed top cover fixedly connected to the top of the reaction vessel, a drive motor mounted on the top of the sealed top cover, a stirring rod mounted at the center of the sealed top cover, stirring blades fixedly connected to the lower side of the stirring rod, and a temperature sensor mounted on the edge of the sealed top cover.

[0009] Furthermore, a gas feed pipe is provided on the right side of the reactor, and one end of the gas feed pipe is connected to a buffer tank, which is connected to the reactor by a pipeline.

[0010] Furthermore, a drive gear plate is installed at the bottom end of the sealing top cover. The drive gear plate is connected to the output shaft of the drive motor. The stirring rod and the sealing top cover are rotatably connected by a bearing. A driven gear plate is welded to the outside of the stirring rod.

[0011] Furthermore, the stirring rod has a hollow interior and a circulating cooling pipe is provided from the top to the inside of the stirring rod.

[0012] Furthermore, an infrared sensor is installed on the bottom edge of the sealed top cover, and the infrared sensor is connected to the temperature sensor via telecommunications.

The water inlet pipe is connected to the circulation pipe.

[0014] Furthermore, a gas sensor is installed on the outer surface of the reactor, and a buzzing alarm is electrically connected to the top of the gas sensor.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. By setting up a temperature control component, during preparation, sodium hydroxide solution is injected into the reactor through the solution feed pipe, and then chlorine gas is introduced into the reactor through the gas feed pipe. At the same time, the stirring rod drives the stirring blades to stir in the reactor, ensuring uniform mixing of chlorine gas and solution. The temperature inside the reactor is monitored in real time by an infrared sensor, and the monitoring data is transmitted to a temperature sensor.

[0017] 2. By setting up a temperature control component, water is injected into the connecting ring frame through the water inlet pipe, and then circulated to the bottom of the reactor through the circulation pipe to cool the inner wall of the reactor. At the same time, the circulating water can remove the heat generated during the reaction, maintain the temperature stability inside the reactor, and improve the efficiency and quality of sodium hypochlorite preparation. Meanwhile, the gas sensor monitors the gas around the reactor in real time. When harmful gases or chlorine concentrations exceed the standard, the gas sensor transmits a signal to the buzzing alarm, which immediately sounds an alarm to remind the staff to take timely measures to ensure production safety.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figure 1-4 As shown, this utility model provides a technical solution: a sodium hypochlorite disinfectant preparation device, including a mounting bracket 1, a reaction vessel 2 welded to the inner side of the mounting bracket 1, a temperature control component 3 disposed inside the reaction vessel 2, the temperature control component 3 including a solution feed pipe 301 disposed on the left side of the reaction vessel 2, a sealing top cover 304 fixedly connected to the top of the reaction vessel 2, a drive motor 305 installed at the top of the sealing top cover 304, a stirring rod 307 installed at the center of the sealing top cover 304, a stirring blade 309 fixedly connected to the lower side of the stirring rod 307, and a temperature sensor 310 installed on the edge of the sealing top cover 304.

[0026] like Figure 1-4 As shown, a gas feed pipe 302 is provided on the right side of the reactor 2. One end of the gas feed pipe 302 is connected to a buffer tank 303. The buffer tank 303 is connected to the reactor 2 by a pipeline. During preparation, sodium hydroxide solution is injected into the reactor 2 through the solution feed pipe 301. Then, chlorine gas is transported into the reactor 2 through the gas feed pipe 302. When entering the reactor 2, the chlorine gas will first pass through the buffer tank 303, thereby reducing the pressure of the chlorine gas entering the reactor 2, ensuring the stability of the gas pressure in the reactor 2, and ensuring safe use.

[0027] like Figure 1-4 As shown, a drive gear 306 is installed at the bottom of the sealed top cover 304. The drive gear 306 is connected to the output shaft of the drive motor 305. The stirring rod 307 is rotatably connected to the sealed top cover 304 by a bearing. A driven gear 308 is welded to the outside of the stirring rod 307. The driven gear 308 and the drive gear 306 are meshed. The drive motor 305 drives the drive gear 306 to rotate, thereby driving the driven gear 308 to rotate. This causes the stirring rod 307 to drive the stirring blades 309 to stir in the reaction vessel 2, ensuring uniform mixing of chlorine gas and solution.

[0028] like Figure 1-4 As shown, the stirring rod 307 has a hollow internal structure. A circulating cooling pipe is provided from the top of the stirring rod 307 to the inside. The stirring rod 307 is cooled from the inside through the circulating cooling pipe to prevent the temperature of the stirring rod 307 from getting too high during the stirring process, which would affect the preparation effect of sodium hypochlorite.

[0029] like Figure 1-4As shown, an infrared sensor 311 is installed on the bottom edge of the sealed top cover 304. The infrared sensor 311 is connected to the temperature sensor 310 via telecommunications. The infrared sensor 311 monitors the temperature inside the reactor 2 in real time and transmits the monitoring data to the temperature sensor 310. The temperature sensor 310 transmits the temperature inside the reactor 2 back to the operator based on the received data, so that the temperature inside the reactor 2 can be monitored at any time to ensure the preparation effect of sodium hypochlorite.

[0030] like Figure 1-4 As shown, a connecting ring frame 312 is installed between the inner walls of the reactor 2. A circulation pipe 313 is provided at the bottom of the connecting ring frame 312, and a water inlet pipe 314 is installed at the top of the connecting ring frame 312. The water inlet pipe 314 is connected to the circulation pipe 313. Water is injected into the connecting ring frame 312 through the water inlet pipe 314, and then the water is circulated to the bottom of the reactor 2 through the circulation pipe 313 to cool the inner wall of the reactor 2. At the same time, the circulating water can remove the heat generated during the reaction, maintain the temperature stability inside the reactor 2, and improve the preparation efficiency and quality of sodium hypochlorite.

[0031] like Figure 1-4 As shown, a gas sensor 315 is installed on the outer surface of the reactor 2. A buzzer alarm 316 is electrically connected to the top of the gas sensor 315. The gas sensor 315 monitors the gas around the reactor 2 in real time. When the concentration of harmful gas or chlorine exceeds the standard, the gas sensor 315 transmits a signal to the buzzer alarm 316, which immediately sounds an alarm to remind the staff to take timely measures to ensure production safety.

[0032] Working Principle: The device is installed in the working position. Sodium hydroxide solution is then injected into the reaction vessel 2 through the solution inlet pipe 301. Chlorine gas enters the reaction vessel 2 stably after being regulated by the gas inlet pipe 302 and the buffer tank 303. The drive motor 305 is started, driving the drive gear disc 306 to rotate. Through meshing with the driven gear disc 308, the stirring rod 307 and stirring blades 309 are driven to stir inside the reaction vessel 2, ensuring that the chlorine gas and sodium hydroxide solution are fully mixed and react. Simultaneously, the circulating cooling pipe inside the stirring rod 307 continuously operates, effectively preventing the stirring rod 307 from overheating due to friction during stirring, thus ensuring the preparation effect. Meanwhile, the infrared sensor 311 monitors the reaction process. The temperature inside the reactor 2 is monitored in real time, and the data is transmitted to the temperature sensor 310 so that the operator can monitor and adjust the reaction temperature at any time. When the temperature inside the reactor 2 is detected to be too high, cooling water is injected into the connecting ring frame 312 through the water inlet pipe 314. The cooling water circulates through the circulation pipe 313 to cool the inner wall of the reactor 2 and remove the heat generated during the reaction, thus maintaining the stability of the reaction temperature. Finally, the gas sensor 315 monitors the gas around the reactor 2 in real time. Once harmful gas or chlorine concentration exceeds the standard, an alarm is immediately triggered by the buzzing alarm 316 to ensure production safety. This completes the use of a sodium hypochlorite disinfectant preparation device.

[0033] Although 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 alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
