Description

Technical Field

[0001] This utility model relates to the field of paint booth exhaust gas treatment technology, specifically to a paint booth odor absorption and treatment device. Background Technology

[0002] A spray booth is a sealed room where treated objects are sprayed with paint. The sealed room increases the quality of the paint spraying and prevents dust in the air from mixing with the paint. However, the spraying process generates paint exhaust gas, which is harmful, so a device is needed to purify this exhaust gas.

[0003] Most paint booth exhaust gas treatment systems use activated carbon adsorption devices. Traditional activated carbon adsorption devices often use a fixed frame structure to house the activated carbon plates. During replacement, workers must use various tools to painstakingly remove layers of protective covers, sealing components, and numerous fasteners such as bolts and clips securing the activated carbon plates. This process is complex and time-consuming. Some activated carbon adsorption devices, in pursuit of higher adsorption efficiency, employ multi-layered or complexly staggered arrangements of activated carbon plates. Because different layers of activated carbon plates require different replacement times, the deeper plates are often obscured. Replacement requires removing multiple outer layers of activated carbon plates before accessing and replacing the saturated inner plates, significantly increasing the complexity and time cost of the replacement process. Utility Model Content

[0004] This invention addresses the shortcomings of existing technologies by providing a spray booth odor absorption and treatment device, thereby solving the problem of cumbersome replacement of multi-layer activated carbon plates when using activated carbon adsorption devices as described in the background.

[0005] To achieve the above technical objectives, this utility model proposes the following technical solution: an odor absorption and treatment device for a spray booth, comprising a spray booth, a purification water tank on one side of the spray booth, an L-shaped air outlet pipe inside the purification water tank, one end of the air outlet pipe penetrating the side wall of the spray booth and communicating with the spray painting work area of ​​the spray booth, an exhaust fan inside the air outlet pipe, a purification tank connected to the air outlet of the purification water tank via a connecting pipe, the purification tank being installed on the top of the spray booth, a rotating shaft inside the purification tank, multiple fixing brackets and a baffle on the side of the rotating shaft, an activated carbon plate being detachably installed on the fixing brackets, an air inlet connected to the connecting pipe being opened at the bottom of the purification tank on one side of the baffle, an exhaust pipe being provided at the top of the purification tank on the other side of the baffle, and an openable replacement door being provided on the side wall of the purification tank.

[0006] Furthermore, the fixing frame includes an upper U-shaped frame and a lower U-shaped frame that are mirror-symmetrical, and the top of the upper U-shaped frame, the bottom of the lower U-shaped frame, and the upper and lower ends of the baffle are all provided with a first elastic plate.

[0007] Furthermore, a second elastic plate is provided on the side of the fixed frame and the baffle away from the rotating shaft. L-shaped connecting plates are fixed to both the upper and lower ends of the second elastic plate on one side of the fixed frame. The L-shaped connecting plates are connected to the fixed frame by pins. The cross-sections of the first elastic plate and the second elastic plate are both semi-circular structures.

[0008] Furthermore, a ladder is installed on one side of the spray booth.

[0009] Furthermore, one end of the rotating shaft passes through the top of the purification tank and is hinged to an operating rod. The top of the purification tank has multiple positioning buckles that match the number of fixing frames and baffles and are used to fix the operating rod.

[0010] Furthermore, there are three fixing brackets, and the three fixing brackets and one baffle are evenly distributed on the side of the rotating shaft. The top of the purification tank is marked with a serial number corresponding to the position of each fixing bracket.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model drives the fixing frame to rotate through the rotating shaft, which can directly rotate the activated carbon plate to be replaced to the replacement door without removing the external multi-layer structure or complex fasteners, greatly reducing the complexity of the replacement operation and shortening the replacement time; the first elastic plate and the second elastic plate on the fixing frame and the baffle are both designed with a semi-circular cross section, which can fit tightly against the inner wall of the purification tank, effectively preventing exhaust gas leakage and ensuring the purification effect.

[0016] The following are specific embodiments of the present invention, and the technical solution of the present invention will be further described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0017] This utility model provides an odor absorption and treatment device for a spray booth, including a spray booth 1. A purification water tank 2 is provided on one side of the spray booth 1. An L-shaped air outlet duct 3 is provided in the purification water tank 2. One end of the air outlet duct 3 passes through the side wall of the spray booth 1 and communicates with the spraying work area of ​​the spray booth 1. An exhaust fan 4 is provided in the air outlet duct 3. The air outlet of the purification water tank 2 is connected to a purification tank 5 through a connecting pipe 4. The purification tank 5 is located on the top of the spray booth 1. A rotating shaft 6 is provided in the purification tank 5. Multiple fixing brackets 7 and a baffle are fixed on the shaft side of the rotating shaft 6. 8. The function of the baffle 8 is to make the exhaust gas in the purification tank 5 flow in a set direction. The fixed frame 7 is detachably installed with activated carbon plate 9. The bottom of the purification tank 5 and on one side of the baffle 8 is provided with an air inlet connected to the connecting pipe 4. The top of the purification tank 5 and on the other side of the baffle 8 is provided with an exhaust pipe 10. The side wall of the purification tank 5 is provided with an openable replacement door 11. The connection between the replacement door 11 and the purification tank 5 is provided with a sealing gasket to improve the sealing performance of the replacement door 11 and prevent the exhaust gas in the purification tank 5 from leaking out during use.

[0018] like Figure 1 and 2 As shown, the exhaust gas generated in the spray painting work area of ​​the spray booth 1 is drawn into the purification water tank 2 by the exhaust fan 4 along the L-shaped exhaust pipe 3. The exhaust gas comes into contact with the water in the purification water tank 2, filtering out water-soluble substances and particulate matter such as dust in the exhaust gas. After preliminary filtration by water, the exhaust gas enters the purification tank 5 along the connecting pipe 4. In the purification tank 5, it passes through multiple activated carbon plates 9 in sequence for adsorption treatment, adsorbing non-water-soluble organic matter, odors and other substances. After treatment, the gas is discharged into the atmosphere through the exhaust pipe 10. The activated carbon plates 9 need to be replaced regularly. The rotating shaft 6 can be driven to rotate the activated carbon plates 9 to one side of the replacement door 11. By opening the replacement door 11, the activated carbon plates 9 can be removed from the fixing frame 7 and replaced with new activated carbon plates 9. Compared with the traditional replacement method that requires the removal of multiple layers of external activated carbon plates first, this utility model can reduce the complexity of the replacement process and save time and costs.

[0019] The fixing frame 7 includes an upper U-shaped frame 71 and a lower U-shaped frame 72 that are mirror-symmetrical. The top of the upper U-shaped frame 71, the bottom of the lower U-shaped frame 72, and the upper and lower ends of the baffle 8 are all fixedly connected to a first elastic plate 73.

[0020] like Figure 2 As shown, the upper and lower ends of the activated carbon plate 9 are installed inside the upper U-shaped frame 71 and the lower U-shaped frame 72. The function of the first elastic plate 73 is to improve the sealing between the upper U-shaped frame 71 and the lower U-shaped frame 72 and the upper and lower bottom walls of the purification tank 5, respectively.

[0021] The fixed frame 7 and the baffle 8 are both provided with a second elastic plate 74 on the side away from the rotating shaft 6. The second elastic plate 74 on the side of the baffle 8 is fixedly connected to the baffle 8. L-shaped connecting plates 75 are fixedly connected to both the upper and lower ends of the second elastic plate 74 on the side of the fixed frame 7. The L-shaped connecting plates 75 are connected to the fixed frame 7 by a pin 76. The cross-section of the first elastic plate 73 and the second elastic plate 74 is a semi-circular structure.

[0022] like Figure 2 and 3 As shown, the function of the second elastic plate 74 is to improve the sealing between the fixed frame 7 and the baffle 8 and the inner wall of the purification tank 5. The activated carbon plate 9 is inserted into the upper U-shaped frame 71 and the lower U-shaped frame 72, and the second elastic plate 74 is installed on the outside of the upper U-shaped frame 71 and the lower U-shaped frame 72. The second elastic plate 74 is installed on the outside of the fixed frame 7 through the L-shaped connecting plate 75 and the pin 76, which on the one hand prevents the activated carbon plate 9 from sliding out of the fixed frame 7, and on the other hand fixes the second elastic plate 74.

[0023] A ladder 12 is installed on one side of the spray booth 1.

[0024] like Figure 1 As shown, the ladder 12 allows construction workers to easily climb up the spray booth 1 to open the replacement door 11 and replace the activated carbon board 9.

[0025] One end of the rotating shaft 6 passes through the top of the purification tank 5 and is hinged to an operating rod 13. The top of the purification tank 5 has multiple positioning buckles 14 that are adapted to the number of fixing frames 7 and baffles 8 and are used to fix the operating rod 13.

[0026] like Figure 1 As shown, the operating lever 13 provides a force point for rotating the shaft 6. According to the position of the activated carbon plate 9 to be replaced, the operating lever 13 is rotated to the designated position of the positioning buckle 14 and the operating lever 13 is locked on the corresponding positioning buckle 14 to prevent the shaft 6 from rotating during replacement.

[0027] There are three fixing frames 7. The three fixing frames 7 and one baffle 8 are evenly fixedly distributed on the side of the rotating shaft 6. The top of the purification tank 5 is marked with a serial number corresponding to the position of each fixing frame 7.

[0028] like Figure 2 As shown, the purification tank 5 is divided into four equal parts by three fixing brackets 7 and a baffle 8. The gas passes evenly through the activated carbon plate 9. By using the operating rod 13 with the positioning buckle 14 and the serial number label, the position of the activated carbon plate 9 to be replaced can be accurately located to avoid misoperation.

[0029] Operating principle: Preliminary filtration: The exhaust gas generated by the paint booth 1 enters the purification water tank 2 through the L-shaped air duct 3 under the action of the exhaust fan, and reacts with the water in the tank. Water-soluble substances and particulate matter such as dust are filtered out; Deep adsorption: The exhaust gas after preliminary filtration enters the bottom air inlet of the purification tank 5 through the connecting pipe 4. Under the guidance of the baffle 8, it passes through multiple activated carbon plates 9 in sequence. Non-water-soluble organic matter, odors, etc. are adsorbed. The purified gas is discharged into the atmosphere from the exhaust pipe 10 at the top of the purification tank 5.

[0030] The replacement procedure for activated carbon plate 9 is as follows: Rotate the shaft 6 using the operating lever 13 to move the fixing bracket 7 (corresponding to the serial number marked on the purification tank 5) to the side of the replacement door 11, and fix the operating lever 13 with the positioning buckle 14 to prevent the shaft 6 from rotating; open the replacement door 11 on the side wall of the purification tank 5, remove the second elastic plate 74 on the fixing bracket 7 (connected to the pin 76 through the L-shaped connecting plate 75), take out the saturated activated carbon plate 9, install the new activated carbon plate 9, reinstall the second elastic plate 76, close the replacement door 12 to complete the replacement, and then rotate the shaft 6 in the opposite direction to return the operating lever 13 to its original position, so that each activated carbon plate 9 is reset.

[0031] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
