[0026] In order to facilitate the understanding of the above technical scheme of the utility model, the working principle or operation mode of the utility model in the actual process is described in detail below.

[0027] In practical application, the sealing cover 3 can be tightly attached to the dust blocking cavity box body 2; the dust blocking cavity box body 2 is used to accommodate the dust blocking limiting support 6, support the sealing cover 3, and cooperate with the sealing cover 3 to seal.

[0028] The sealing cover 3 is provided with a matched buckle 4 on both sides of the dust blocking cavity box body 2. When sealing, the buckle 4 is only pulled tight to make the sealing cover 3 tightly attached to the dust blocking cavity box body 2; when the dust curtain 7 needs to be replaced, the buckle 4 is only gently released by the construction personnel, the sealing cover 3 is provided with a handle 5, and the construction personnel is convenient to lift up. Only the sealing cover 3, the dust blocking limiting support 6, the dust curtain 7 and the adjusting mechanism 8 are lifted out together to replace the dust curtain 7, the bolt 603 is locked, and it can be put back, without stopping the line to complete.

[0029] The middle area of the sealing cover 3 is welded with a rectangular limiting outer tube 801 and a screw rod seat 808. The rectangular limiting outer tube 801 is provided with the fixed screw rod seat 808 at the upper end, the hand wheel 809 drives the screw rod 804 to move up and down along the screw rod seat 808 in a straight line; the rectangular limiting inner tube 802 smaller than the rectangular limiting outer tube 801 is welded and fixed above the flat plate 601 to prevent the dust curtain 7 from tilting forward and backward during use of the device, causing poor sealing effect; the rib plate 803 is added to prevent the flat plate 601 from deforming. The rectangular limiting inner tube 802 is welded with the shaft sleeve 806 at the bottom. The space of the shaft sleeve 806 is reserved at the bottom of the screw rod 804 to ensure smooth rotation of the screw rod 804, and the baffle 807 and the pull plate 805 are welded (i.e. fixed on the screw rod 804). When the screw rod 804 rotates downward, the pull plate 805 moves downward, at this time, the pull plate 805 is separated from the bottom end of the shaft sleeve 806 (under normal circumstances, the top end of the pull plate 805 is in contact with the bottom end of the shaft sleeve 806 to realize the supporting effect of the shaft sleeve 806), so that the shaft sleeve 806, the rectangular limiting inner tube 802 and the dust blocking limiting support 6 move downward under the action of gravity until they contact the pull plate 805 again to realize supporting and limiting, thereby completing the downward adjustment of the dust blocking limiting support 6. In addition, after long-term use, the surface of the rectangular limiting inner tube 802 will accumulate a lot of dust, which will be unable to fall freely due to resistance. When the screw rod 804 and the pull plate 805 move downward, the rectangular limiting inner tube 802 cannot continue to fall freely and contacts the pull plate 805, at this time, the downward adjustment of the dust blocking limiting support 6 can be realized by moving the shaft sleeve 806 and the rectangular limiting inner tube 802 downward through the baffle 807. When rotating upward, the pull plate 805 can pull up the dust blocking limiting support 6 through the shaft sleeve 806 and the rectangular limiting inner tube 802. The dust curtain connecting plate 602 is welded below the flat plate 601, the dust curtain connecting plate 602 is provided with a slot hole 604, the left and right positions of the dust curtain 7 can be adjusted, and the dust curtain 7 can be directly replaced later. In addition, the device of the embodiment can also be applied to multi-channel S-shaped damping dust curtain arrangement, the dust curtain is separated left and right for debugging, the walking path of dust airflow is prolonged, multi-stage filtration and adsorption of dust can make the dust on the dust curtain surface settle.

[0030] In summary, by means of the above technical scheme of the utility model, the utility model can not only adjust the height of the dust screen 7 to the undamaged area when the dust screen 7 is seriously worn, thereby effectively making full use of the dust screen 7, prolonging the replacement cycle of the dust screen 7 and reducing the cost, but also the whole replacement device (i.e. the sealing cover 3, the handle 5, the dust blocking limiting support 6, the dust screen 7 and the adjusting mechanism 8) can be easily and independently disassembled, the dust screen 7 does not need to be replaced with the line stopped, only the replacement device needs to be lifted, the tension bolt 603 is loosened, the dust screen 7 is replaced, and then the cover is put on, thereby making the replacement of the dust screen 7 more simple and efficient, and simultaneously, the utility model can also better seal the material guide groove by adjusting the dust screen 7 up and down and left and right, thereby better meeting the use demand of enterprises.
