Detailed Description

In accordance with the concepts of the present application, an embodiment of a dust extraction duct is provided herein in conjunction with the accompanying drawings. Referring to fig. 1 to 6, the dust removal pipe 100 comprises a connecting plate 200 and a retractable cloth bag 300, wherein the connecting plate 200 is hermetically connected to two ends of the retractable cloth bag 300 for splicing adjacent dust removal pipes 100 together to form a channel with a proper length, and the retractable cloth bag 300 is used for realizing the retractable function of the dust removal pipe 100.

Specifically, the connection plate 200 has a hanging lug 210 for connection with the slide 400; the lower portion of the connecting plate 200 is provided with an air outlet 230 facing to the smoke flowing direction, the air outlet 230 is located inside the telescopic cloth bag 300, the air outlet 230 is used for blowing up smoke particles falling on the bottom of the telescopic cloth bag 300, the air outlet 230 is communicated with a plurality of air inlet holes 240 located at the bottom of the connecting plate 200, the end portions of the air inlet holes 240 are provided with one-way vent valves 260, and the one-way vent valves 260 can ensure that outside air flows into the telescopic cloth bag 300 in a one-way mode. Connect a plurality of these dust removal pipelines 100 after splicing with negative pressure apparatus for producing, form the negative pressure environment in this dust removal pipeline 100, the smoke and dust is taken away after flowing through this dust removal pipeline 100, simultaneously, outside air is behind one-way admission valve 260 and inlet port 240, discharge by gas outlet 230, gas outlet 230 is towards the direction that the smoke and dust flows, can be to the effect that the production secondary that the falling smoke and dust granule and deposit can in flexible sack 300 bottom smoke and dust blows, the effectual deposit that reduces the smoke and dust granule in the pipeline.

In addition, in order to ensure that the dust removal process is performed more efficiently and reliably, various detail modifications may be made with respect to the connection plate 200 of the dust removal duct, one by one as described below.

For example, a plurality of connection holes 220 for being spliced with each other are uniformly distributed on the periphery of the connection plate 200, and a bolt is used to pass through the connection holes 220, so that two adjacent dust removal pipelines 100 can be connected, and meanwhile, in order to ensure the connection tightness, a sealing gasket can be arranged between the connection plates 220.

For another example, the hanging lugs 210 are symmetrically arranged on the top of the connecting plate 200, and the sliding channels 400 penetrate through the holes of the hanging lugs 210, so that the stability of the dust removal pipeline 100 in sliding along the sliding channels 400 is ensured.

The air outlet 230 may be an arc-shaped structure, and the width of the air outlet 230 is greater than the width of the inner cavity of the connecting plate 200, so that the air outlet 230 covers the bottom of the retractable cloth bag 300 as much as possible, and the air outlet 230 can blow away all the smoke particles falling on the bottom of the retractable cloth bag 300.

In addition, an installation groove 250 is provided at an end of the air intake hole 240, and the one-way airing valve 260 is fixed in the installation groove 250 by a screw 270.

In order to ensure a long service life, the stretchable cloth bag 300 is made of a high temperature resistant material.

Subsequently, the working principle of the dust removing duct in the foregoing concept in the dust removing process will be described with reference to the accompanying drawings.

When the sand box with the wear-resistant part is dedusted, the dedusting pipeline is spliced and then installed on the slideway, two ends of the spliced pipeline are respectively connected with the negative pressure generating device and the cover box, the cover box is used for covering the upper part of the sand box to be dedusted, the negative pressure generating device is opened, a negative pressure environment is formed in the dedusting pipeline, smoke generated by the sand box is sucked away through the dedusting pipeline (in the direction shown by the arrow in figure 2), meanwhile, the outside air passes through the one-way vent valve and the air inlet hole and is discharged from the air outlet (in the direction shown by the arrow in figure 6), the air discharged from the air outlet can be directly blown to the bottom of the telescopic cloth bag, smoke particles deposited at the bottom of the telescopic cloth bag are blown away, and the deposition of the smoke particles at the bottom of the telescopic cloth bag.

The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
