The restraining frame is pulled outward to separate the restraining frame from the swing door, and then the swing door is opened, and the shielding plate is driven to separate from the door frame by the swing door, and vice versa, the shielding plate is reclosed, and then the bolt is tightened, and the shielding plate is squeezed by the bolt to make the shielding plate press and seal the door frame. In the process, the restraining frame is used to restrain the swing door, which is convenient for opening the door frame opening or reclosing the door frame opening, thereby facilitating the maintenance of the waste gas treatment equipment.

[0008] Preferably, the door frame comprises a first frame body, a stop block, a guide frame and a bearing seat, wherein the guide frame is fixedly connected to the front end of the first frame body, the stop block is fixedly connected to the upper end of the guide frame, and the bearing seat is fixedly connected to the outer end of the first frame body. The guide frame is used to conveniently guide the sliding of the restraining frame, and the stop block is used to conveniently limit the sliding range of the restraining frame.

[0009] Preferably, the binding frame comprises a second frame body, and a slide groove is provided at the inner end of the second frame body, so as to facilitate the sliding connection between the limit block and the binding frame.

[0010] Preferably, the swing door comprises a rotating frame and a door body, wherein the rotating frame is fixedly connected to the door body as a whole. The door body is conveniently constrained by the binding frame, and the shielding plate is conveniently guided to slide by the door body.

[0011] Preferably, the swing door further comprises a nut, which is fixedly connected to the outer end of the door body, so as to increase the thread connection range between the swing door and the bolt.

[0013] Preferably, the shielding plate includes a plate body and a slide rod, and the slide rod is evenly fixedly connected to the outer end of the plate body. When the threaded rod loosens the shielding plate, the elastic force of the spring is used to drive the plate body to separate from the first frame body, so that the shielding plate can be easily released from the door frame.

[0014] In summary, the technical effects and advantages of the utility model are as follows:

[0015] 1. Pull the restraining frame outward to separate the restraining frame from the swinging door, then open the swinging door, and use the swinging door to drive the shielding plate to separate from the door frame. Otherwise, close it again, and then tighten the bolts. Use the bolts to squeeze the shielding plate so that the shielding plate presses and seals the door frame. During the process, use the restraining frame to restrain the swinging door, which is convenient for opening the door frame or reclosing the door frame, thereby facilitating the maintenance of the exhaust gas treatment equipment.
