Detailed Description
The utility model is further described below in connection with the following examples which are provided for the purpose of better understanding of the present utility model and are, therefore, not to be construed as limiting the scope of the utility model.
Referring to fig. 1-2, a flexible gravity air locking device comprises a section of inclined pipeline 1, wherein the section of the pipeline 1 is rectangular, two parallel fixing clamping plates 2 are transversely arranged on an upper side plate of an inner cavity of the pipeline 1, flexible air locking baffles 3 are fixedly connected between the two fixing clamping plates 2 through bolts 5, the width of each flexible air locking baffle 3 is equal to that of the inner cavity of the pipeline 1, the bottom edge of each flexible air locking baffle 3 is in contact with a lower side plate of the inner cavity of the pipeline 1 after sagging, a counterweight 4 is arranged at the bottom of each flexible air locking baffle 3 and close to a discharging side, the counterweight 4 is fixedly connected with each flexible air locking baffle 3 through bolts, and access doors 7 are respectively arranged on the pipeline 1 and on the upper side and the lower side of each fixing clamping plate 2; the device is convenient to overhaul.
A U-shaped sealing baffle plate 6 is arranged in the inner cavity of the pipeline 1 and positioned at one side of the flexible air locking baffle plate 3 close to the feeding direction, the sealing baffle plate 6 is in a vertical state and is respectively in full-welded connection with two side plates and the lower side plate of the pipeline 1, and one side of the sealing baffle plate 6 is contacted with the edge of the flexible air locking baffle plate 3; the airtight performance when the device does not have the material downstream is increased, so that the air locking effect of the device is better, the flexible air locking baffle 3 can be limited, the flexible air locking baffle 3 is prevented from being sucked upwards in a negative pressure state of the feeding end of the pipeline 1, and the air locking effect is damaged.
