[0002] Sodium hypochlorite is a strong oxidant and is widely used in disinfection, sterilization, cleaning and other aspects. With the increase in demand for sodium hypochlorite, a large amount of sodium hypochlorite needs to be produced. At present, electrolytic cells are generally used in the production of sodium hypochlorite. Sodium hypochlorite electrolytic cells are produced by electrolyzing salt water to generate sodium hypochlorite through electrolytic reaction. In real life, sodium hypochlorite electrolytic cells are used in various occasions, such as disinfection and sterilization work in hospitals, schools, hotels, food processing plants and other places.

[0003] The existing sodium hypochlorite electrolytic cell is generally composed of an electrolytic cell body, electrodes, wires, a power supply and other parts. The required sodium hypochlorite is generated by adding saline solution into the cell body and applying electricity to the cell body for electrolysis.

When the temperature is too high, it is easy to cause damage to the electrolytic cell. When the temperature is too low, it will affect the electrolysis efficiency and product quality. At the same time, the electrode tube is easily corroded after long-term use, and the service life is short. In order to solve this technical problem, the utility model proposes a sodium hypochlorite electrolytic cell with dual cold and heat sources and controllable temperature. Utility Model Content

When the temperature is too low, the inside of the tank body is heated by the heating tube to achieve a warming effect, thereby keeping the temperature inside the tank body constant to prevent overheating or overcooling, thereby solving the existing problem that the temperature cannot be accurately controlled, when the temperature is too high, it is easy to cause damage to the electrolytic cell, when the temperature is too low, it will affect the electrolysis efficiency and product quality, and at the same time, the electrode tube is easily corroded after long-term use, and the service life is poor.

[0015] In the utility model, by arranging components such as a detection mechanism, when the temperature sensor is damaged or too much dirt is accumulated on the outer surface and needs to be cleaned, the twisting block can be twisted, and the twisting block drives the rotating block to rotate, so that the rotating block drives the temperature sensor to be pulled out from the inside of the tank body, thereby facilitating the cleaning or replacement of the temperature sensor to avoid affecting the temperature detection effect. After the cleaning is completed, the rotating block is screwed on, so that the rotating block moves downward close to the sealing gasket, thereby squeezing the sealing gasket, increasing the sealing effect through the sealing gasket, and preventing the fluid inside the tank body from overflowing.

DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] like Figure 1-4 As shown, a sodium hypochlorite electrolytic cell with dual cold and hot sources and controllable temperature includes a cell body 1, which is made of a transparent material, and the reaction process inside the cell body 1 can be seen. A titanium tube electrode 2 is arranged inside the cell body 1, and the outer surface of the titanium tube electrode 2 is sprayed with a ruthenium coating. The titanium tube electrode 2 can be powered to electrolyze brine, and the ruthenium coating on the titanium tube electrode 2 can protect the titanium tube electrode 2 from corrosion, thereby increasing the service life of the titanium tube electrode 2.

[0024] A heating tube 3 is provided inside the tank body 1, and the temperature inside the tank body 1 can be increased through the heating tube 3. Freon refrigerant is provided inside the heating tube 3. The gas Freon is compressed by a compressor to become a high-temperature and high-pressure gas, which enters the heating tube 3 to liquefy and release heat, and at the same time heats the inside of the tank body 1. A cooling tube 4 is also provided inside the tank body 1, and the cooling tube 4 is used to cool the inside of the tank body 1. The end of the cooling tube 4 is connected to an external water source, and the heat inside the tank body 1 can be taken away by the flow of water, thereby cooling the inside of the tank body 1.

[0025] The top of the tank body 1 is provided with a detection mechanism 5, which includes a rotating block 501, a temperature sensor 502 is fixedly connected to the lower surface of the rotating block 501, and the temperature sensor 502 is connected to an external controller, and all electronic components in the device can be controlled by the controller. A screw block 503 is fixedly connected to the upper surface of the rotating block 501, and a fixing ring 504 is threadedly connected to the outer surface of the rotating block 501, and the lower surface of the fixing ring 504 is fixedly connected to the tank body 1. By screwing the screw block 503, the screw block 503 drives the rotating block 501 to rotate, so that the rotating block 501 drives the temperature sensor The sensor 502 can move upward or downward. A support plate 506 is arranged below the rotating block 501. The outer surface of the support plate 506 is fixedly connected to the titanium tube electrode 2. The upper surface of the support plate 506 is fixedly connected to a sealing gasket 505. The upper surface of the sealing gasket 505 contacts the rotating block 501. The outer surface of the temperature sensor 502 penetrates the sealing gasket 505 and the support plate 506 in sequence. When the rotating block 501 moves downward close to the sealing gasket 505, the sealing gasket 505 can be squeezed to increase the sealing effect through the sealing gasket 505 to prevent the fluid inside the tank body 1 from overflowing.

[0026] A feed pipe 6 and a discharge pipe 7 are installed at the bottom of the tank body 1. Valves are provided on the feed pipe 6 and the discharge pipe 7. The feed pipe 6 is used to allow brine to enter the interior of the tank body 1, and the discharge pipe 7 is used to discharge the finished product after the reaction.

[0027] A mounting plate 8 is provided on the side of the tank body 1, and a fixing plate 9 is fixedly connected to the outer surface of the tank body 1. One side of the fixing plate 9 is detachably connected to the mounting plate 8. The fixing plate 9 and the mounting plate 8 are fixed by bolts and can be disassembled when necessary. The end of the titanium tube electrode 2 is installed on the mounting plate 8, and a connecting wire 10 is installed at the end of the titanium tube electrode 2. A terminal 11 is provided on the outer surface of the connecting wire 10, and power is supplied through the connecting wire 10. A support block 12 is installed on the inner wall of the mounting plate 8. There are four support blocks 12, of which the inner walls of two support blocks 12 are fixedly connected to the heating tube 3, and the inner walls of the other two support blocks 12 are fixedly connected to the cooling tube 4. The support block 12 is used to support and fix the heating tube 3 and the cooling tube 4. An electronic expansion valve 13 is installed on the outer side of the tank body 1 of the heating tube 3. The electronic expansion valve 13 is used to control the flow of Freon in the heating tube 3. The cooling tube 4 is located on the outer side of the tank body 1 and an electromagnetic two-way valve 14 is installed. The electromagnetic two-way valve 14 is used to control the flow of cold water.

[0028] It should be noted that, in actual use of the device, the valve on the feed pipe 6 is first opened to allow the brine to enter the interior of the tank body 1, and the titanium tube electrode 2 electrolyzes the brine. The ruthenium coating on the titanium tube electrode 2 protects the titanium tube electrode 2 from corrosion, thereby increasing the service life of the titanium tube electrode 2. During the electrolysis process, the temperature inside the sensor is sensed in real time by the temperature sensor 502. When the temperature is too high, the electromagnetic two-way valve 14 is opened to allow cooling water to enter from the end of the cooling tube 4, thereby reducing the temperature of the cooling tube 4. The cooling tube 4 reduces the temperature of the brine, thereby cooling the interior of the tank body 1, achieving a cooling effect. When the temperature is too low, the electronic expansion valve 13 is opened to allow the Freon gas to enter the heating tube 3, and the interior of the tank body 1 is heated by the heating tube 3, thereby achieving a warming effect, thereby keeping the temperature inside the tank body 1 constant to prevent overheating or overcooling. After the reaction is completed, the discharge pipe 7 is opened to discharge the finished product after the reaction.

[0029] When the temperature sensor 502 is damaged or too much dirt accumulates on the outer surface and needs to be cleaned, the screw block 503 can be twisted, and the screw block 503 drives the rotating block 501 to rotate, so that the rotating block 501 drives the temperature sensor 502 to be pulled out from the inside of the tank body 1, thereby facilitating the cleaning or replacement of the temperature sensor 502 to avoid affecting the temperature detection effect. After cleaning, the rotating block 501 is screwed on to move the rotating block 501 downward toward the sealing gasket 505, thereby squeezing the sealing gasket 505, thereby increasing the sealing effect through the sealing gasket 505 and preventing the fluid inside the tank body 1 from overflowing.
