[0002] Paint is the traditional Chinese term for coatings. It is an engineering material that can be applied to the surface of an object through different construction techniques to form a continuous film. It has excellent protective and decorative functions, as well as good anti-corrosion and isolation functions. During the paint production process, a large amount of paint-containing waste gas is generated. It is necessary to extract and discharge a large amount of paint waste gas to the outside in a timely manner, and to draw a large amount of fresh air from the environment and send it to the paint spraying plant to ensure a safe and hygienic working environment. Usually, paint waste gas needs to be treated by adsorption and filtration of waste gas purification equipment before being discharged.

[0003] However, the existing paint exhaust gas purification devices have relatively complicated internal purification mechanisms that are difficult to disassemble and assemble, and the subsequent cleaning or replacement is also complicated, which has certain drawbacks. Utility Model Content

[0004] The purpose of this invention is to provide a device for purifying paint waste gas, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a device for purifying paint exhaust gas, comprising a purification box, an air inlet pipe fixedly inserted into one side of the bottom of the purification box, an exhaust pipe fixedly inserted into one side of the top of the purification box, an opening and closing door provided on the front surface of the purification box, the opening and closing door being hinged to the purification box by multiple torque hinges, an installation plate fixedly connected inside the purification box, the installation plate being hollow, a filter screen and an activated carbon filter plate being provided inside the installation plate, and support plates fixedly connected to the inner walls at both ends of the installation plate. Both ends are provided with limiting plates, which are fixedly connected to the inner wall of the mounting plate. One side of the support plate is provided with a rotating groove, and a threaded rod is rotatably connected in the rotating groove. The threads on both sides of the center point of the horizontal axial section of the threaded rod are arranged in opposite directions. One end of the threaded rod is fixedly connected to a rotating rod, and one end of the rotating rod passes through the support plate and is fixedly connected to a rotating block. Both ends of the threaded rod are threaded with moving plates, and both ends of the moving plates are rotatably connected to traction rods. One end of the traction rod is rotatably connected to a connecting block, and one side of the connecting block is fixedly connected to a pressure plate.

[0006] Preferably, a stop rod is slidably inserted into one end of the rotating block, and a rubber clamp is fixedly connected to one end of the stop rod. The outer wall of the support plate is provided with multiple slots corresponding to the rubber clamp.

[0007] Preferably, a vertical pole is fixedly connected inside the exhaust pipe, and a suction fan is fixedly connected to the vertical pole.

[0008] Preferably, telescopic rods are fixedly connected to both ends of the movable plate and the inner wall of the mounting plate.

[0009] Preferably, the bottom of the purification box is fixedly connected to four rectangular universal self-locking wheels.

[0010] Preferably, the outer side wall of the rotating block is provided with multiple anti-slip grooves arranged at an angle.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This device for purifying paint exhaust gas introduces exhaust gas into the purification chamber through an inlet pipe. The exhaust gas is filtered for particulate impurities by a filter screen, and then adsorbed and filtered by an activated carbon filter plate before being discharged through an exhaust pipe. The filter screen and activated carbon filter plate are respectively installed on the upper and lower sides of the mounting plate and are limited by a limiting plate. By rotating the rotating block, the rotating rod is driven to rotate, causing the threaded rod to rotate in the rotating groove on the support plate. When the threaded rod rotates, the two moving plates threaded onto it move relative to each other, causing the traction rod to move. At this time, the traction rod pushes the pressure plate to move, thereby fixing the two ends of the filter screen and activated carbon filter plate. This utility model facilitates the disassembly and assembly of the purification mechanism through the setting of the clamping and fixing components, making subsequent cleaning and maintenance convenient and easy to operate.

One end of the rod is fixedly connected to a rotating rod 11. One end of the rotating rod 11 passes through the support plate 9 and is fixedly connected to a rotating block 12. Both ends of the threaded rod 10 are threadedly sleeved with movable plates 13. Both ends of the movable plates 13 are rotatably connected to traction rods 14. One end of the traction rod 14 is rotatably connected to a connecting block 15. One side of the connecting block 15 is fixedly connected to a pressure plate 16. Specifically, the filter screen 7 and the activated carbon filter plate 8 are respectively installed on the upper and lower sides of the mounting plate 6 and are limited by the limiting plate 23. By rotating the rotating block 12, the rotating rod 11 is driven to rotate, causing the threaded rod 10 to rotate in the rotating groove on the support plate 9. When the threaded rod 10 rotates, the two movable plates 13 threadedly sleeved on it move relative to each other, causing the traction rod 14 to move. At this time, the traction rod 14 will push the pressure plate 16 to move, thereby fixing the two ends of the filter screen 7 and the activated carbon filter plate 8.

[0021] In this embodiment, a stop rod 17 is slidably inserted into one end of the rotating block 12, and a rubber clamp 18 is fixedly connected to one end of the stop rod 17.

Multiple anti-slip grooves are provided on the outer wall of the rotating block 12 to prevent slippage during rotation.

[0022] Working principle: First, exhaust gas is introduced into the purification box 1 through the air inlet pipe 2. The exhaust gas is filtered for particulate impurities through the filter screen 7, and then adsorbed and filtered through the activated carbon filter plate 8 before being discharged through the exhaust pipe 3. The filter screen 7 and the activated carbon filter plate 8 are respectively installed on the upper and lower sides of the mounting plate 6 and are limited by the limiting plate 23. By rotating the rotating block 12, the rotating rod 11 is driven to rotate, causing the threaded rod 10 to rotate in the rotating groove on the support plate 9. When the threaded rod 10 rotates, the two moving plates 13 threaded on it move relative to each other, causing the traction rod 14 to move. At this time, the traction rod 14 will push the pressure plate 16 to move, thereby fixing the two ends of the filter screen 7 and the activated carbon filter plate 8.

[0023] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
