The brine is preheated and sent for electrolysis. The electrolyte is preheated, evaporated, salted, and cooled.

[0003] A Chinese patent with the relevant announcement number CN217403202U discloses a material cooling device for inorganic chemical production, including a tank body, a feed pipe is arranged on the top of the tank body, a discharge pipe is arranged on the bottom of the tank body, a control valve is arranged on the discharge pipe, and a cooling device is arranged in the inner cavity of the tank body. The cooling device includes a cooling coil arranged on the inner wall of the tank body, the cooling coil is connected to a condensation component, and a stirring component is arranged on the inner wall of the tank body.

[0004] With respect to the above-mentioned related technologies, in actual use, the existing material cooling device for inorganic chemical production fills the tank with materials for cooling, and then discharges the materials from the tank structure after cooling. The whole process takes a long time, and the cooled materials cannot be obtained quickly. It is difficult to quickly cool the chemical materials and obtain cooled materials. Therefore, the existing material cooling device for inorganic chemical processing is difficult to perform continuous material cooling work. Utility Model Content

[0005] Based on this, the purpose of the utility model is to provide a material cooling device for inorganic chemical processing to solve the technical problem that the existing material cooling device for inorganic chemical processing is difficult to perform continuous material cooling work.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a material cooling device for inorganic chemical processing, comprising a box body, wherein the box body is provided with a plurality of channels in the vertical direction, a cooling pipe is coaxially fixedly connected in the channel, an axial flow fan for blowing air downward is provided at the top of the cooling pipe, a material inlet and a material outlet for material inflow and outflow are respectively provided at both ends of the box body, a water storage tank is provided at the bottom end of the box body, a surrounding plate is fixedly connected to the top end of the box body, and a pump for pumping water in the water storage tank into the surrounding plate is provided on the side wall of the box body.

[0007] By adopting the above technical scheme, an axial flow fan is used to generate an airflow flowing along the inner wall of the cooling pipe, so that cooling water flows between the outer wall of the cooling pipe and the inner wall of the channel. The cooling water contacts the inner wall of the channel, and the chemical materials in the box are efficiently cooled. At the same time, the airflow generated by the axial flow fan cools the cooling pipe, and then dissipates the heat of the cooling water, which effectively increases the speed of heat dissipation of the chemical materials, thereby achieving effective cooling of the chemical materials when flowing through the box structure, so that the cooled chemical materials can be obtained immediately.

[0008] The utility model is further configured that baffles are rotatably connected to both sides of the bottom end of the box body, and the bottom end of the baffle is close to the water storage tank and does not contact the water storage tank.

[0009] By adopting the above technical solution, the cooling water can be further cooled, thereby improving the cooling effect of the cooling water on the materials in the box.

[0010] The utility model is further configured such that the height of the top end of the channel is lower than the height of the top end of the enclosure plate.

[0011] By adopting the above technical solution, the top of the channel is lower than the top of the enclosure plate, which prevents the cooling water from flowing out without being blocked by the enclosure plate.

[0012] The utility model is further configured such that a water inlet pipe of the pump extends into the water storage tank, and a water outlet pipe is connected to a side wall of the enclosure.

[0013] By adopting the above technical solution, the cooling water can fall from between the inner wall of the channel and the outer wall of the cooling pipe due to its own gravity.

[0014] The utility model is further configured such that the bottom end of the cooling pipe extends out of the box body.

[0015] By adopting the above technical solution, the cooling water can fall smoothly along the inner wall of the channel and the outer wall of the cooling pipe.

[0016] The utility model is further configured such that the cooling pipe is water-permeable but air-impermeable.

[0017] By adopting the above technical solution, the cooling water that permeates the cooling pipe reduces its temperature under the action of high-speed airflow, further improving the cooling effect of the cooling water on the materials in the box.

[0018] The utility model is further configured such that the height of the top end of the cooling pipe is higher than the height of the enclosure water inlet pipe.

[0019] By adopting the above technical solution, the cooling water is prevented from accumulating in the enclosure and flows directly down from the cooling pipe, thereby effectively protecting the motor of the axial flow fan.

[0020] In summary, the utility model mainly has the following beneficial effects:

[0021] The utility model arranges a plurality of channels in a box structure along a vertical direction, arranges a cooling pipe that can penetrate water in the channel, and uses an axial flow fan to generate an airflow flowing along the inner wall of the cooling pipe, so that cooling water flows between the outer wall of the cooling pipe and the inner wall of the channel. The cooling water contacts the inner wall of the channel, and the chemical materials in the box are efficiently cooled. At the same time, the airflow generated by the axial flow fan cools the cooling pipe, and then dissipates the heat of the cooling water, effectively improving the speed of heat dissipation of the chemical materials, thereby achieving effective cooling of the chemical materials when flowing through the box structure, so that the cooled chemical materials can be obtained immediately.

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0030] The following describes an embodiment of the utility model based on its overall structure.

[0031] Embodiment 1

[0032] A material cooling device for inorganic chemical processing, such as Figure 1-6As shown, the box body 1 includes a box body 1, which is provided with multiple channels 2 in the vertical direction. Specifically, the box body 1 is provided with six vertical channels 2, the distance between the inner wall of the channel 2 and the outer wall of the cooling pipe 3 inside it is two centimeters, the cooling pipe 3 is coaxially fixedly connected in the channel 2, and an axial flow fan 4 for blowing air downward is provided at the top of the cooling pipe 3. The two ends of the box body 1 are respectively provided with a material inlet 9 and a material outlet 10 for material inflow and outflow, a water storage tank 7 is provided at the bottom end of the box body 1, a surrounding plate 5 is fixedly connected to the top of the box body 1, and a pump 8 for pumping water in the water storage tank 7 into the surrounding plate 5 is provided on the side wall of the box body 1.

[0033] See also Figure 3-6 The cooling pipe 3 is water-permeable but air-impermeable. The cooling pipe 3 specifically adopts a hard water-washed cotton board. While maintaining the airflow flowing along the axial direction, the cooling water can also penetrate between the inner wall of the channel 2 and the outer wall of the cooling pipe 3 to the inner wall of the cooling pipe 3. The cooling water that penetrates the cooling pipe 3 reduces the temperature under the action of the high-speed airflow, further improving the cooling effect of the cooling water on the material in the box body 1. The bottom end of the cooling pipe 3 extends out of the box body 1, avoiding the air outlet of the cooling pipe 3 to generate positive pressure in the channel 2 and block the normal fall of the cooling water, so that the cooling water can fall smoothly between the inner wall of the channel 2 and the outer wall of the cooling pipe 3.

[0034] See also Figure 1-4 The height of the top of the channel 2 is lower than the height of the top of the enclosure 5. The cooling water at the top of the box body 1 is blocked by the enclosure 5 and gathered. The gathered cooling water flows downward along the annular space between the inner wall of the channel 2 and the outer wall of the cooling pipe 3. The top of the channel 2 is lower than the top of the enclosure 5 to prevent the cooling water from flowing out without being blocked by the enclosure 5. The water inlet pipe of the pump 8 extends into the water storage tank 7, and the water outlet pipe is connected to the side wall of the enclosure 5. The pump 8 is used to pump the cooling water in the water storage tank 7 into the space surrounded by the enclosure 5, so that the cooling water can fall from the inner wall of the channel 2 and the outer wall of the cooling pipe 3 under its own gravity. The height of the top of the cooling pipe 3 is higher than the height of the water inlet pipe of the enclosure 5, which avoids the accumulation of cooling water in the enclosure 5 and directly flows down from the cooling pipe 3, effectively protecting the motor of the axial flow fan 4.

[0035] Embodiment 2

[0036] A material cooling device for inorganic chemical processing, such as Figure 1-6As shown, baffles 6 are rotatably connected to both sides of the bottom of the box body 1, and the bottom end of the baffle 6 is close to the water storage tank 7 and does not contact the water storage tank 7. When multiple sets of axial flow fans 4 generate downward airflow flowing out of the cooling tube 3, a high-speed airflow area is generated below the bottom end of the cooling tube 3. According to the Bernoulli principle, a low-pressure area is generated below the cooling tube 3, so that the two baffles 6 rotate toward each other and approach each other under the action of the airflow generated by the axial flow fan 4, blocking part of the falling cooling water to prevent the cooling water from spilling out of the water storage tank 7. In addition, since the cooling water wets the windward surface of the baffle 6, the high-speed airflow causes the water to evaporate and can also cool the baffle 6. The baffle 6 further cools the cooling water by heat conduction with the subsequent falling cooling water, thereby enhancing the cooling effect of the cooling water on the material in the box body 1.

[0037] The working principle of the utility model is as follows: liquid material flows into the box body 1 from the material inlet 9 and flows out from the material outlet 10. During the flow of the material in the box body 1, the cooling water accumulated in the enclosure 5 flows downward along the annular cross-sectional space formed by the inner wall of the channel 2 and the outer wall of the cooling pipe 3. The cooling water exchanges heat with the inner wall of the channel 2 to cool the material flowing in the box body 1. At the same time, the cooling water penetrates through the cooling pipe 3. The airflow generated by the axial flow fan 4 arranged in the cooling pipe 3 cools the cooling pipe 3, thereby playing a role in reducing the temperature of the cooling water and improving the cooling effect of the cooling water on the material. The cooling water falling from the bottom end of the channel 2 is sprinkled on the baffle 6, and the airflow flowing out from the bottom end of the cooling pipe 3 blows on the side of the baffle 6 sprinkled with cold water, which can further increase the cooling speed of the cooling water, thereby making the cooling water falling into the water storage tank 7 drop to a low temperature state, and is pumped to the top of the box body 1 by the pump 8 to re-participate in the cooling work. The material flowing through the box body 1 is continuously cooled, thereby achieving the purpose of stable and continuous material cooling.

The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contribution as needed without departing from the principles and purpose of the utility model.
