Description

Technical Field

[0001] This utility model relates to the technical field of exhaust cooling devices, specifically an exhaust cooling device for paint spraying booths. Background Technology

[0002] In the field of spray booths, heat dissipation devices are key equipment for ensuring stable working temperatures and improving spraying quality and efficiency. These devices typically dissipate heat generated inside the spray booth by promoting airflow and enhancing heat exchange, thereby maintaining a suitable spraying and baking environment. Traditional heat dissipation devices may include components such as exhaust fans, water curtain systems, and heat exchangers, all designed to optimize heat management and improve equipment performance.

[0003] However, since the gas entering the spray booth generally only passes through the water curtain and has little contact time with it, the cooling pipes in the water curtain have a poor cooling effect on the gas. At the same time, after long-term use, a large amount of dust and impurities may accumulate inside the water curtain, which will obstruct the gas and reduce the efficiency of the water curtain in cooling the gas, thus reducing the heat dissipation efficiency of the spray booth. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides an exhaust cooling device for spray painting booths. This device solves the problems mentioned in the background section, where the gas entering the spray painting booth typically only passes through a water curtain, resulting in limited contact time with the water curtain. Consequently, the cooling pipes in the water curtain have a poor cooling effect on the gas. Furthermore, after prolonged use, the water curtain may accumulate a large amount of dust and impurities, which can obstruct the gas flow and further reduce the cooling efficiency of the water curtain, thus decreasing the overall heat dissipation efficiency of the spray painting booth.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: an exhaust and heat dissipation device for a paint spraying booth, comprising:

[0008] The spray booth shell has an exhaust fan installed at the air outlet and an air inlet installed on the other side of the spray booth shell.

[0009] A cooling rack is installed inside the air inlet. An installation rack is installed on the inner wall of the paint spraying booth shell at a position corresponding to the cooling rack. Installation grooves are opened on the inner walls of the front and rear sides of the installation rack. Installation blocks are installed on the front and rear sides of the cooling rack. The installation blocks are inserted into the installation grooves. Threaded rods are screwed onto the upper and lower parts of the surface of the installation blocks.

[0010] The mounting frame is located in the middle of the cooling rack. Cooling pipes are installed inside the mounting frame and are evenly distributed inside the mounting frame. Protective cloth is installed on all the openings on the surface of the mounting frame.

[0011] Preferably, a water tank is installed on the surface of the paint spraying booth shell, a water pump is installed at the outlet of the water tank, and an inlet pipe is installed at the outlet of the water pump. The inlet pipe is connected to the inlet of the cooling pipe. When the water pump is started, water from inside the water tank can be injected into the cooling pipe through the inlet pipe. A semiconductor refrigeration module is installed on the surface of the water tank.

[0012] Preferably, the outlet end of the cooling pipe is equipped with a water outlet pipe, and the outlet end of the water outlet pipe is connected to the inlet of the water tank. Water in the cooling pipe can be injected into the water tank through the water outlet pipe, thereby realizing water circulation in the cooling pipe. Water that has absorbed heat in the cooling pipe can be injected into the water tank, and water with a lower temperature in the water tank can be injected into the cooling pipe, so that the cooling pipe can effectively cool the incoming gas.

[0013] Preferably, filter frames are installed on both the left and right sides of the cooling rack, and filter screens are installed on the surface of the filter frames to prevent dust from adhering to the surface of the protective cloth.

[0014] Preferably, a sealing gasket is installed on the surface of the filter frame on the right side. The sealing gasket is in close contact with the inner wall of the paint spraying booth shell.

[0015] Beneficial effects

[0016] Compared with the prior art, this utility model provides an exhaust and heat dissipation device for spray painting booths, which has the following beneficial effects:

[0017] This spray booth uses an exhaust cooling system. An exhaust fan draws hot air out of the booth, allowing outside air to enter through the inlet. Upon entering, the air comes into contact with the cooling pipes, effectively dissipating heat. The cooling rack can be disassembled by removing the threaded rod, allowing for cleaning of the protective cloth. This ensures smooth airflow through the cloth, and the perforations in the cloth distribute the air evenly across the cooling pipes, maximizing contact. The air is positioned between two pieces of cloth, and the small pores in the cloth further increase the contact time, effectively cooling the air and improving the overall cooling efficiency of the spray booth.

[0026] 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.

[0027] This utility model provides a technical solution: an exhaust and heat dissipation device for a paint spraying booth. (Please refer to...) Figure 1 Including the outer shell of the spray painting booth 1, please refer to Figure 2 The exhaust vent of the paint spray booth shell 1 is equipped with an exhaust fan 2. Please refer to [link / reference]. Figure 1 An air inlet 3 is installed on the other side of the paint spraying booth shell 1;

[0028] Cooling rack 4 is located inside air inlet 3. Please refer to [link / reference]. Figure 3 The inner wall of the spray booth 1 is fitted with mounting brackets 5 at positions corresponding to the cooling rack 4. Please refer to [link / reference]. Figure 7 Mounting slots 6 are provided on the inner walls of both the front and rear sides of the mounting bracket 5. Please refer to [link / reference]. Figure 4The cooling rack 4 has mounting blocks 7 installed on both the front and rear sides. The mounting blocks 7 are inserted into the mounting slots 6. Threaded rods 8 are screwed onto the upper and lower parts of the surface of the mounting blocks 7.

[0029] Please see Figure 4 Mounting frame 9 is located in the middle of cooling rack 4. Please refer to [link / reference]. Figure 6 Cooling pipes 10 are installed inside the mounting frame 9. The cooling pipes 10 are evenly distributed inside the mounting frame 9. Protective cloth 11 is installed on all the openings on the surface of the mounting frame 9.

[0030] The exhaust fan 2 can extract the hot air from inside the spray booth. At this time, the external air will enter the spray booth through the air inlet 3. When the air enters the spray booth, it will come into contact with the surface of the cooling pipe 10, and the air can more effectively dissipate heat from the spray booth. At the same time, the cooling rack 4 can be disassembled by removing the threaded rod 8, and the protective cloth 11 can be cleaned, so that the air can pass smoothly through the protective cloth 11. The holes on the surface of the protective cloth 11 can evenly distribute the incoming air on the surface of the cooling pipe 10, so that the air can fully contact the surface of the cooling pipe 10, which can accelerate the cooling effect of the air.

[0031] Please see Figure 1 A water tank 12 is installed on the surface of the paint spraying booth shell 1. Please refer to [link / reference]. Figure 3 A water pump 13 is installed at the outlet of the water tank 12. An inlet pipe 14 is installed at the outlet of the water pump 13. The inlet pipe 14 is connected to the inlet of the cooling pipe 10. When the water pump 13 is started, water inside the water tank 12 can be injected into the cooling pipe 10 through the inlet pipe 14. A semiconductor refrigeration module is installed on the surface of the water tank 12.

[0032] The cooling pipe 10 is equipped with a water outlet pipe 141, which is connected to the water inlet of the water tank 12. Water from the cooling pipe 10 can be injected into the water tank 12 through the water outlet pipe 141, thereby realizing water circulation in the cooling pipe 10. Water that has absorbed heat in the cooling pipe 10 can be injected into the water tank 12, and water with a lower temperature in the water tank 12 can be injected into the cooling pipe 10, so that the cooling pipe 10 can effectively cool the incoming gas.

[0033] Please see Figure 4 The cooling rack 4 has filter frames 15 installed on both the left and right sides, and filter screens 16 are installed on the surface of the filter frames 15. The filter screens 16 can prevent dust from adhering to the surface of the protective cloth 11.

[0034] Please see Figure 5A sealing gasket 17 is installed on the surface of the filter frame 15 on the right side. The sealing gasket 17 is in close contact with the inner wall of the paint spraying booth shell 1. The sealing gasket 17 can seal the cooling rack 4 and the air inlet 3. The filter frame 15 and the mounting frame 9 are combined to form the cooling rack 4.

[0035] In operation, this solution works as follows: First, the exhaust fan 2 extracts the hot air from inside the spray booth. At this time, the external air enters the spray booth through the air inlet 3. When the air enters the spray booth, it comes into contact with the surface of the cooling pipe 10, which can more effectively dissipate heat from the spray booth. Then, the threaded rod 8 can be removed to disassemble the cooling rack 4, allowing the protective cloth 11 to be cleaned. This allows the air to pass smoothly through the protective cloth 11, and the holes on the surface of the protective cloth 11 can evenly distribute the incoming air onto the surface of the cooling pipe 10, ensuring full contact between the air and the surface of the cooling pipe 10 and accelerating the cooling effect. Finally, after the protective cloth 11 is cleaned, the cooling rack 4 is installed in the mounting bracket 5 using the threaded rod 8. This also causes the sealing gasket 17 to seal the cooling rack 4 and the air inlet 3, ensuring that the air entering the spray booth can fully contact the cooling pipe 10, further improving the heat dissipation effect of the spray booth.
