In the free state, the roller 26 of the control valve 2 is located between the upper and lower edges of the opening flap 4. As shown in fig. 4 and 14, when the opening flap 4 moves above one or more control valves 2, the opening flap 4 cooperates with the roller 26 to swing the swing lever 23 away from the vertical position, thereby opening the control valves 2. At this time, the control valve 2 located below the opening damper 4 is in an open state, and the control valve 2 not located below the opening damper 4 is in a closed state.

The second connecting plate 31 is fixedly connected with the opening baffle 4 through screws. The reason for this design is that the size and range of the smoke generated by different materials are different, and the number of the control valves 2 which are opened by the opening baffles 4 at the same time needs to be adjusted according to the types of the materials and the situation of dust removal on site in the actual use process, so that the opening baffles 4 need to be replaced.

When the dust collector is used, the carrier vehicle 52 loaded with materials moves along the conveying mechanism 51, the opening baffle 4 connected with the carrier vehicle 52 through the cantilever rod 3 moves synchronously, the opening baffle 4 pushes the swinging rod 23 to rotate around the hinge shaft 24 at the position where the carrier vehicle 52 passes through, so that the control is in an open state, at the moment, smoke dust enters the dust collection pipeline under the action of the draught fan, and accordingly, dust excited by discharging materials is pertinently sucked into the dust collection pipeline through the dust collection cover 13. Through the design of fixed point dust absorption, under the prerequisite of guaranteeing dust removal effect, reduced the energy consumption, practiced thrift the running cost.

Two connecting cylinders are symmetrically arranged in the second square frame. The connecting cylinder comprises a connecting cylinder body 221, and an outer flange 222 is arranged at the outer end (the opposite side of the two connecting cylinders is the inner side) of the connecting cylinder body 221. The middle of the connecting cylinder body 221 is provided with a first connecting plate 224 which is square, and the first connecting plate 224 is fixedly connected with the second square frame through a screw.

A valve plate 27 which can move up and down relative to the second square frame is arranged between the two connecting cylinders in the second square frame, and a spring 281 which is used for preventing the valve plate 27 from moving upwards relative to the second square frame is arranged between the valve plate 27 and the second square frame.

When the roller 26 of the control valve 2 is disengaged from the opening flapper 4, the valve plate 27 of the control valve 2 moves downward by the elastic restoring force of the spring 281, thereby re-closing the control valve 2. The device can always ensure that one or more controls are in an open state, the rest control valves 2 are in a closed state, and the control valves 2 in the open state correspond to the moving position of the gantry 62.

The second connecting plate 31 is fixedly connected with the opening baffle 4 through screws. The reason for this is that the number of the opening damper 4 that simultaneously opens the control valve 2 needs to be adjusted according to the situation of dust removal on site during actual use, and therefore the opening damper 4 needs to be replaced.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
