Description

Technical Field

[0001] This application relates to the field of cooling devices, and more particularly, to a cooling device for producing sodium hydroxide. Background Art

[0002] Generally, during the production of sodium hydroxide, chemical reactions between raw materials often occur. During the reaction process, it is necessary to control the reaction temperature. Generally, the reaction temperature is between 100 and 200 degrees Celsius, and the temperature can be adjusted by heating or cooling. According to the specific situation of the reaction, the reaction time is generally between several hours and dozens of hours. Therefore, a cooling device is often used to cool the reaction kettle. However, many cooling devices are not convenient for heat preservation. The reaction temperature needs to be controlled within a certain range. If heat preservation is not convenient, the reaction time may be too long or too short. Both too long and too short reaction times will affect the yield and purity of sodium hydroxide. Utility Model Content

[0003] To make up for the above deficiencies, this application provides a cooling device for producing sodium hydroxide, aiming to improve the problem that many cooling devices are not convenient for heat preservation. The reaction temperature needs to be controlled within a certain range. If heat preservation is not convenient, the reaction time may be too long or too short. Both too long and too short reaction times will affect the yield and purity of sodium hydroxide.

[0004] An embodiment of this application provides a cooling device for producing sodium hydroxide, including a reaction kettle and a temperature adjustment component. Heat preservation plates are symmetrically and rotatably connected to the outside of the reaction kettle, and are drivingly connected between the two heat preservation plates. A motor is arranged at the bottom of one of the heat preservation plates, and the motor is fixedly connected to one side of the reaction kettle. The temperature adjustment component includes a spiral flat tube, a spiral heat dissipation tube, a heat dissipation box, a water pump, and a heating box. The spiral flat tube is fixedly sleeved on the outer wall of the reaction kettle. One side of the upper part of the spiral flat tube is communicated with one end of the spiral heat dissipation tube. The spiral heat dissipation tube is fixedly connected to the heat dissipation box. One side of the bottom of the spiral heat dissipation tube is communicated with the heat dissipation box. The heat dissipation box, the water pump, and the heating box are all arranged on one side of the reaction kettle. One side of the upper part of the spiral flat tube is communicated with the input end of the water pump. The input end of the water pump is communicated with one side of the heat dissipation box. The output end of the water pump is communicated with one side of the heating box. The other side of the heating box is communicated with one side of the bottom of the spiral flat tube.

[0005] In a specific implementation, a gear is arranged on one side of the heat preservation plate, and the two gears are meshingly connected.

[0006] In the above implementation process, the meshing connection between the two gears will cause the two heat preservation plates to rotate synchronously.

[0007] In a specific embodiment, the reaction kettle is provided with a limiting groove matching the heat preservation plate, and one side of the heat preservation plate abuts against the inner wall of the limiting groove.

[0008] In the above implementation process, the setting of the limiting groove facilitates the positioning of the heat preservation plate, thereby facilitating the limitation of the position of the heat preservation plate.

[0009] In a specific embodiment, the input end of the water pump is respectively provided with a first water pipe and a second water pipe. One end of the first water pipe is communicated with the water pump, the other end of the first water pipe is communicated with one side of the heat dissipation box, one end of the second water pipe is communicated with the first water pipe, and the other end of the second water pipe is communicated with one side of the upper part of the spiral flat tube.

[0010] In the above implementation process, the setting of the first water pipe realizes the connection between the water pump and the heat dissipation box, and the setting of the second water pipe realizes the connection between the first water pipe and the spiral flat tube.

[0011] In a specific embodiment, a first solenoid valve is arranged on one side of the spiral flat tube, a second solenoid valve is arranged on the side of the first water pipe close to the heat dissipation box, and a third solenoid valve is arranged on one side of the second water pipe.

[0012] In the above implementation process, when the first solenoid valve is closed, the spiral flat tube can be shunted into the second water pipe. At this time, the third solenoid valve arranged on the second water pipe is opened, and the second solenoid valve arranged on the first water pipe is closed. The water inside the spiral flat tube is directly conveyed into the water pump, and then conveyed into the heating box through the water pump. After heating, it is conveyed into the spiral flat tube again to heat or keep warm the reaction kettle. When the first solenoid valve is opened, the third solenoid valve is closed, and the second solenoid valve is opened. At this time, the water inside the spiral flat tube will flow into the spiral heat dissipation tube, dissipate heat through the spiral heat dissipation tube, and then be conveyed into the water pump through the heat dissipation box. The water pump conveys the cooled water into the spiral flat tube to cool the reaction kettle. During the processes of cooling and heat preservation heating, the temperature of the reaction kettle is adjusted.

[0013] In a specific embodiment, a bracket is arranged on the upper part of one side of the heat dissipation box, and the spiral heat dissipation tube is fixedly connected with the bracket.

[0014] In the above implementation process, the setting of the bracket facilitates the support of the spiral heat dissipation tube and also facilitates the fixation of the fan.

[0015] In a specific embodiment, the bracket is provided with fans, and a plurality of fans are arranged.

[0016] In the above implementation process, the setting of the fans blows air to dissipate heat from the spiral heat dissipation tube.

[0017] In a specific embodiment, the heating box includes a box body, an electric heating tube and a temperature controller. One side of the box body is communicated with one side of the bottom of the spiral flat tube, and the other side of the box body is communicated with the water pump. The electric heating tube is fixedly connected inside the box body, the temperature controller is fixedly connected to the upper part of the box body, and the temperature controller is electrically connected to the electric heating tube.

[0018] In the above implementation process, the setting of the box body can transport water into the interior of the box body, and the electric heating tube heats the water inside the box body.

[0019] Beneficial effects: The present application provides a cooling device for producing sodium hydroxide. When heating or insulating the reaction kettle, the water pump transports water into the heating box. The water is heated by the heating box, and the heated water is transported into the spiral flat tube. The spiral flat tube transfers the temperature in the water to the reaction kettle to insulate or heat the reaction kettle. Controlling the temperature of the water heated by the heating box can achieve insulation of different temperatures for the reaction kettle. When it is necessary to cool down the reaction kettle, the water in the spiral flat tube is transported into the spiral heat dissipation tube. After being dissipated by the spiral heat dissipation tube and the heat dissipation box, the water is then transported back into the heating box. At this time, the heating function of the heating box is turned off, and the water is transported into the spiral flat tube again. The water in the spiral flat tube takes out the temperature of the reaction kettle and is dissipated by the spiral heat dissipation tube again, thus realizing the recycling of water. During the whole use process, heating, insulation and cooling of the reaction kettle are realized, the temperature of the reaction kettle can be accurately adjusted according to production needs, the reaction time can be reasonably controlled, and the yield and purity of sodium hydride are ensured.
