Description

Technical Field

[0001] The utility model relates to the field of electrophoretic coating, in particular to an electrophoretic waste gas treatment device. Background Art

[0002] Electrophoretic coating is a coating method that puts the workpiece and the corresponding electrode into a water-soluble coating, connects to the power supply, and relies on the physical and chemical effects generated by the electric field to make the resin and pigment in the coating uniformly precipitate and deposit on the surface of the coated object as the electrode to form a water-insoluble paint film. A large amount of electrophoretic waste gas will be generated during the electrophoretic process. These waste gases will pollute the environment and cause certain harm to the human body. Therefore, these waste gases need to be collected and treated. However, the existing waste gas treatment device has a simple structure and a small processing capacity. Especially when there is too much waste gas, the waste gas treatment device will stop working due to exceeding the processing capacity range, causing the electrophoretic assembly line to stop working and wait; the existing waste gas treatment device does not pre-treat the impurities in the waste gas during the treatment process, so that the impurities fill the entire treatment device, often blocking the vents therein, which leads to serious blockage of the vents over time, and the waste gas processing capacity is rapidly reduced. The machine has to be shut down for cleaning and maintenance, which greatly reduces the waste gas treatment efficiency and affects production efficiency. Summary of the invention

[0003] In order to solve one or some technical problems existing in the prior art, the purpose of this application is to provide an electrophoresis exhaust gas treatment device that can increase the treatment volume of electrophoresis exhaust gas, improve the exhaust gas treatment efficiency, reduce the cleaning and maintenance rate of the treatment device, and ensure the normal progress of electrophoresis.

[0004] In order to solve the above-mentioned existing technical problems, the purpose of this application is achieved by adopting the following technical solutions: an electrophoresis waste gas treatment device, including an air inlet pipe, a waste gas collection tower connected to the air inlet pipe, a waste gas impurity removal tower connected to the waste gas collection tower, an activated carbon adsorption device connected to the waste gas impurity removal tower, a waste gas conveying device connected to the activated carbon adsorption device, an electrophoresis waste gas treatment tower connected to the waste gas conveying device, and an outlet pipe arranged at the top of the electrophoresis waste gas treatment tower, a first conveying pipe is arranged between the waste gas collection tower and the waste gas impurity removal tower, the waste gas collection tower and the waste gas impurity removal tower are connected through the first conveying pipe, a second conveying pipe is arranged between the waste gas impurity removal tower and the activated carbon adsorption device, and the waste gas impurity removal tower and the activated carbon adsorption device are connected through the second conveying pipe. Through the impurity removal treatment of the waste gas impurity removal tower and the adsorption treatment of the activated carbon adsorption device, impurities can be effectively removed, the air vents in the electrophoresis waste gas treatment tower can be avoided from being blocked, and the waste gas treatment efficiency can be improved.

The conveying volume of the waste gas can be controlled by the centrifugal fan. When a certain electrophoresis production line is stopped, the corresponding air inlet branch pipe is closed, and the centrifugal fan is controlled to reduce the rotation speed, reduce the conveying volume, and save energy.

[0009] Preferably, the air outlet of the centrifugal fan is provided with a connecting hose connected to the fourth delivery pipe, and the bottom of the base frame is provided with a collecting tank for collecting liquid leaking from the connecting hose. The pretreated exhaust gas is mixed with moisture, which will flow down along the inner wall after condensation, and liquid will leak from the connecting hose and the air outlet of the centrifugal fan. The collecting tank is used to collect the leaked liquid to avoid secondary pollution caused by the spread of the leaked liquid.

[0010] Preferably, a drainage strip is provided on the side wall of the centrifugal fan below the connecting hose, so that the leaked liquid can be drained into the collecting tank, which has a simple structure and is easy to manufacture.

[0011] Preferably, a baffle is provided on the bottom frame below the drain bar, and the outer end of the baffle is tilted upward. The baffle blocks the leaked liquid at the bottom of the drain bar, and then flows into the collection tank along the tilted baffle, avoiding collision and splashing of the leaked liquid at the bottom of the drain bar with the liquid in the collection tank, thereby reducing pollution.
