Description

Ventilation structure for movable paint spraying booth Technical Field The invention relates to the technical field of paint spraying and ventilation, in particular to a ventilation structure for a movable paint spraying booth. Background In the field of steel structure coating, mobile paint spray booths have been increasingly used. The spray booth can run along the track, and continuously spray by covering long rod members or large-section members in sections. In order to ensure that paint mist and exhaust gas generated during the spraying process are effectively collected, the paint booth needs to be equipped with a ventilation structure. The ventilation structure generally includes a secondary air outlet duct that moves with the booth and a primary air outlet duct that is secured to the work area. When the spray booth works at different positions, the auxiliary air outlet channel needs to be communicated with the corresponding interface on the main air outlet channel. The ventilation structure in the prior art has the following problems. First, placement of the joint locations is difficult. The main air outlet channel is usually provided with a plurality of interfaces along the travelling direction of the spray booth, and the auxiliary air outlet channel is provided with a movable interface. How to enable the movable interface and the fixed interface to be accurately abutted after the paint spray booth moves is a design difficulty. If the butt position deviation is large, communication failure or air leakage may be caused. Second, the sealability after the butt joint is difficult to be ensured. After the paint spray booth is stopped, the movable interface needs to be tightly attached to the fixed interface. However, dust and paint mist residues often exist in the field environment, or the interface surface is uneven, so that sealing is easy to be poor. Harmful gas can leak from the gap due to the fact that sealing is not tight, and environmental protection effect and health of operators are affected. Thirdly, the use convenience is insufficient. During docking, an operator may need to manually adjust the interface position or apply additional locking force. This mode of operation increases labor intensity and also reduces the continuous efficiency of the spraying operation. If a complex automatic docking mechanism is used, equipment costs and failure points are increased. Accordingly, there is a need for a ventilation configuration for a mobile paint booth. The structure can simplify the design of the joint position, ensure the sealing reliability after butt joint, improve the operation convenience and realize automatic or semi-automatic quick connection and disconnection. Disclosure of Invention In view of the above, the present invention aims to overcome the defects in the prior art, and provide a ventilation structure for a mobile paint booth, which can reduce pollution and satisfy the spraying operation on special structural members such as a large-section steel structure or a long rod steel structure.
