Abstract
Description
Technical Field
[0001] This utility model relates to the field of automobile manufacturing technology, and in particular to a water swirl barrel centralized paint mist removal device. Background Technology
[0002] In recent years, my country's coating production line equipment technology and market have developed rapidly. The variety of spraying equipment has increased dramatically, product appearance and process requirements have become increasingly stringent, and environmental protection requirements for paint booth emissions have become increasingly stringent across different regions. Consequently, the efficiency of paint mist removal equipment has become increasingly modernized and efficient. Because water-swirling paint mist removal equipment can effectively block and wash away paint mist mixed in the air during the spraying process, ensuring that the air passing through at the end is relatively clean, and because it can be recycled and is easy to control, it is widely used in modern workpiece spraying production lines, and the demand is gradually increasing.
[0003] Painting production lines often require workpieces to be painted on-line. Currently, traditional oil-based paints are widely used in the domestic market. The solvents in oil-based paints contain volatile organic compounds (VOCs), which are released into the air during the paint drying process. Furthermore, due to factors such as different spray gun types, irregular workpiece shapes, arbitrary human factors, and instability in the painting mechanism, overspraying during the oil-based paint spraying process can release harmful substances, polluting the environment and affecting air quality and freshness. At the same time, the disposal of oil-based paint waste is also a major challenge. Because it is difficult to degrade, indiscriminate disposal can pollute soil and water sources, damaging the ecological environment. Utility Model Content
[0004] The purpose of this invention is to provide a water swirl barrel centralized paint mist removal device that captures and separates paint mist by adsorbing and separating the oversprayed paint mist generated during the spraying process through the synergistic effect of water curtain, airflow and centrifugal force.
[0005] To achieve the above objectives, a centralized paint mist removal device with a water swirl barrel is provided, including a top-mounted air supply filter structure. A water curtain plate is fixedly connected to the lower end of the top-mounted air supply filter structure. A filter box is provided on the other side of the top-mounted air supply filter structure. A spray pipe is connected to the lower end of the filter box. A water tank is correspondingly provided at the lower end of the spray pipe. A wind duct is fixedly connected to and connected to the back of the top-mounted air supply filter structure.
[0006] According to the aforementioned water swirl barrel centralized paint mist removal device, a water supply pipe is fixedly connected to one side of the water curtain plate.
[0007] According to the aforementioned water swirl barrel centralized paint mist removal device, an exhaust port is provided on one side of the top air supply filter structure.
[0008] According to the aforementioned water swirl bucket centralized paint mist removal device, a pipeline is fixedly connected to one side of the spray pipe.
[0009] According to the aforementioned water swirl barrel centralized paint mist removal device, a first inspection door and a second inspection door are respectively provided on both sides of the air duct.
[0010] Beneficial effects:
[0011] Paint mist capture and separation utilizes the combined effects of water curtain, airflow, and centrifugal force to adsorb and separate overspray paint mist generated during the spraying process. Compared to traditional dry filtration or ordinary water curtain spray booths, water vortex technology has the following advantages: high-efficiency capture, water conservation and environmental protection, low maintenance costs, and strong adaptability.
