[0002] Organic solvents are essential for synthetic leather companies, such as dimethylformamide, toluene, butanone, ethyl acetate, methyl acetate, etc., so every synthetic leather company needs to store a large amount of them. Organic solvents have the physical properties of being flammable, explosive and volatile. At the same time, as hazardous chemicals, there are certain risk factors and hidden dangers. Especially in the summer when the temperature is high, the volatility of organic solvents is more active. The volatilization of organic solvents will cause increased loss of materials, so it is necessary to spray the surface of the solvent storage tank to cool it down.

[0003] Existing spraying devices often use water circulation to spray and cool the solvent storage tank. The water flow that comes into contact with the solvent storage tank will be collected and sprayed on the solvent storage tank again. After multiple spraying, the water flow affected by the surface temperature of the solvent storage tank will heat up, thereby reducing the cooling effect on the solvent storage tank and reducing the cooling effect of the device. Utility Model Content

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1-4 As shown, an automatic spraying device for a solvent storage tank includes a base 1, a liquid storage tank 7, a protective shell 5 and a spray pipe 6. A liquid collecting chamber 2 is provided on the inner wall of the base 1, and a plurality of water troughs are provided on the surface of the base 1. The water troughs are connected to the liquid collecting chamber 2. A bracket 3 is fixed to the top of the base 1, and an electric push rod 4 is fixed to the surface of the bracket 3. One end of the electric push rod 4 passes through the bracket 3 and is fixedly connected to the protective shell 5. The spray pipe 6 is fixed to the inside of the protective shell 5. The surface of the base 1 where the liquid collecting chamber 2 is located is connected to a delivery pipe 8. A one-way valve is installed on the surface of the delivery pipe 8. The delivery pipe 8 passes through the base 1 and is connected to the liquid storage tank 7. A first water pump 9 is connected to one side of the liquid storage tank 7. A hose 10 is connected to one side of the first water pump 9. One end of the hose 10 passes through the protective shell 5 and is connected to the spray pipe 6. A plurality of nozzles are connected to the surface of the spray pipe 6. A cooling mechanism 11 for cooling the water flow inside the liquid storage tank 7 is provided on one side of the liquid storage tank 7. A temperature sensor 13 is fixed inside the liquid storage tank 7.

[0024] The cooling mechanism 11 includes a second water pump 111, a return pipe 112 and an air cooler 113. The second water pump 111 is connected to the surface of the liquid storage tank 7. The second water pump 111 can pump out the water flow inside the liquid storage tank 7. The second water pump 111 is connected to the return pipe 112. The water flow pumped out by the second water pump 111 can enter the return pipe 112. One end of the return pipe 112 is connected to the surface of the liquid storage tank 7. The water flow inside the return pipe 112 can flow into the liquid storage tank 7 again. The air cooler 113 is arranged on one side of the return pipe 112. The air cooler 113 can blow out cold air to cool down the return pipe 112, so that the water flow inside the return pipe 112 can be cooled.

[0025] The return pipe 112 is arranged in a serpentine structure and is made of copper-aluminum alloy, so that the water flow inside the return pipe 112 can be slowed down, thereby increasing the time the water flow stays inside the return pipe 112 and making the return pipe 112 have a good heat conduction effect.

[0026] The liquid collecting chamber 2 is arranged in a ring shape, and a protective net 12 is fixed on the surface of the water trough, so that the water flow can enter the conveying pipe 8 through the shape of the liquid collecting chamber 2, and the protective net 12 can block the surface of the base 1 to prevent foreign matter from entering the liquid collecting chamber 2.

[0027] The spray pipe 6 is arranged in an annular structure, and a hanging ring is fixed on the surface of the bracket 3. The hose 10 passes through the hanging ring, so that the water flow sprayed from the spray pipe 6 can contact the surface of the solvent storage tank more evenly, and the hanging ring can also provide support for the hose 10.

[0028] A plurality of slide bars 14 are passed through the surface of the bracket 3 , and the surface of the slide bars 14 is fixedly connected to the top of the protective shell 5 . When the protective shell 5 moves, the slide bars 14 will slide on the surface of the bracket 3 , thereby providing the protective shell 5 with a guiding effect.

[0029] Working principle: First, place the solvent storage tank on the surface of the base 1. When cooling, adjust the electric push rod 4 to move the protective shell 5 downward so that the protective shell 5 can cover the top surface of the solvent storage tank. Then start the first water pump 9 to allow the water flow inside the liquid storage tank 7 to be input into the spray pipe 6 through the hose 10, and then sprayed out by the nozzle on the surface of the spray pipe 6, so that the solvent storage tank can achieve a cooling effect. During this period, the protective shell 5 will block the water flow sprayed from the spray pipe 6, so that the water flow is not easy to splash around, and the water flow after spraying will enter the liquid collecting chamber 2 through the water trough, and then flow back into the liquid storage tank 7 through the delivery pipe 8, thereby completing the spray liquid recovery cycle. After the first spraying, the water flow affected by the surface of the solvent storage tank will heat up, and the temperature sensor 13 will detect the water temperature inside the liquid storage tank 7. When the temperature sensor 13 detects that the water temperature inside the liquid storage tank 7 reaches a predetermined value, the second water pump 111 and the air cooler 113 are started to allow the water flow inside the liquid storage tank 7 to enter the return pipe 112, and the air cooler 113 will cool the return pipe 112, so that the water flow inside the liquid storage tank 7 can be cooled, thereby ensuring the cooling effect of the device on the solvent storage tank. At the same time, when the solvent storage tank needs to be taken, the electric push rod 4 is adjusted to move the protective shell 5 upward, and then the solvent storage tank can be taken out from the surface of the base 1.
