Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

In which like parts are designated by like reference numerals. It should be noted that the terms "front," "back," "left," "right," "upper" and "lower" used in the following description refer to directions in the drawings, and the terms "bottom" and "top," "inner" and "outer" refer to directions toward and away from, respectively, the geometric center of a particular component.

As shown in fig. 1 and 2, the periphery of the bottom of a cover body 1 is correspondingly provided with a rolling curtain structure 2, the rolling curtain structure 2 comprises a rolling curtain 21, a bearing part 22 and a driving part 23, the rolling curtain 21 is wound on the bearing part 22, and specifically, the bearing part 22 can adopt a circular tube structure; when the cover body 1 collects air, the bearing part 22 rotates under the power of the driving part 23, and drives the roller shutter 21 to droop to cover the exhaust gas discharge area. Here, the roller blind structure 2 can be fixed around the cover body 1 through the bracket, the mounting head code and the mounting tail code in actual installation, one end of the bracket is fixedly connected with the cover body 1, the other end of the bracket is fixedly connected with the mounting head code and the mounting tail code respectively, and the mounting head code and the mounting tail code are rotatably connected with the bearing part 22.

Because the waste gas source discharge capacity is big, easily the diffusion, the utility model discloses at the book curtain structure 2 that the cover body 1 established all around, roll up curtain structure 2 and can be used for blockking organic waste gas, make organic waste gas keep in the closed region that book curtain structure 2 formed at the gas collection in-process, reduce the probability that organic waste gas diffused in the air, improve the collection efficiency of waste gas, alleviate environmental pollution.

As shown in fig. 2 and 3, the connection relationship between the roller blind 21 and the bearing part 22 is as follows: the bearing part 22 is coaxially fixed with a plurality of reels 221, the roller shutter 21 is connected with the bearing part 22 through a drawing wire 5, one end of the drawing wire 5 is fixed on the reels 221, and the other end is fixedly connected with the roller shutter 21 along the drooping direction of the roller shutter 21. In this embodiment, the driving portion 23 is a tubular motor, the tubular motor is coaxially inserted into the bearing portion 22, the tubular motor is electrically connected to the control switch, a tooth-shaped rotating wheel 231 is fixedly connected to an output shaft of the tubular motor, and a driven ring 222 matched with the tooth-shaped rotating wheel 231 is disposed on an inner wall of the bearing portion 22. When the tubular motor works, the output shaft of the tubular motor rotates to drive the toothed wheel 231 to rotate, the toothed wheel 231 rotates to drive the driven ring 222 to rotate, the driven ring 222 rotates to drive the bearing part 22 to rotate, the bearing part 22 rotates to drive the winder 221 to rotate, and the winder 221 rotates to drive the roller shutter 21 to wind and unwind through the pull wire 5.

In the present embodiment, as shown in fig. 2, when the end of the pull wire 5 away from the reel 221 is fixed to the roll screen 21, the roll screen 21 has a multi-layer pleated structure. When the gas-collecting hood collects the organic waste gas, the rolling screen 21 completely sags, the arc-shaped part 21a at the lower end of the rolling screen 21 is folded, and the rolling screen 21 above the arc-shaped part 21a has a good sagging feeling due to the certain self weight of the arc-shaped part 21a, and meanwhile, the rolling screen 21 is reduced from flying up caused by the exhaust pressure in the organic waste gas discharging process, so that the leakage probability of the organic waste gas is reduced.

As shown in fig. 2, since the rolling blind structure 2 is disposed around the bottom of the housing 1, there may be a gap at a corner between adjacent rolling blinds 21, and organic waste gas may leak from the gap due to external factors such as exhaust pressure, and therefore, flexible sealing structures are disposed at two sides of the rolling blind 21 for sealing the gap at the corner between adjacent rolling blinds 21. The flexible sealing structure comprises bristles 6 and a connecting strip 7, one side of the connecting strip 7 is connected with the roller shutter 21 in a sewing mode, the other side of the connecting strip 7 is connected with the bristles 6 in a sewing mode, flexible connection between the flexible sealing structure and the roller shutter 21 is guaranteed, and rolling and releasing of the roller shutter 21 are not affected while sealing is achieved.

As shown in fig. 2, the brush hairs 6 are perpendicular to the hanging direction of the rolling screen 21, and during the unwinding of the rolling screen 21, because the brush hairs 6 have certain flexibility, during the hanging of the rolling screen 21, the adjacent brush hairs 6 are deformed and crossed to form a net structure, thereby improving the sealing effect on the gaps at the corners of the adjacent rolling screen 21.

Preferably, as shown in fig. 2, the lowest point of the connecting strip 7 is flush with the highest point of the circular arc segment 21b at the end of the rolling screen 21 far away from the bearing part 22. In the process that the roll screen 21 droops completely, the arc part 21a of roll screen 21 is folding, and the connecting strip 7 does not take place to buckle this moment, because the connecting strip 7 does not take place to buckle, just can not cause the perk of connecting strip 7 tip, consequently, roll screen 21 can drooping to covering exhaust emission region, and connecting strip 7 can seal the gap of adjacent roll screen 21 corner, makes organic waste gas be difficult for leaking, further improves the collection efficiency of waste gas.

The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment without inventive contribution as required after reading the present specification, but all of them are protected by patent laws within the scope of the claims of the present invention.
