Description
Technical Field
The invention relates to the technical field of dust prevention in mine exploitation, in particular to a dust suppression device for mine exploitation.
Technical Field
The air shovel is a tool which takes compressed air as power to make a hammer body inside the air shovel perform reciprocating motion and hit a shovel drill rod, so that the shovel drill rod performs chiseling operation. In the process of mining operation, soft ore is beaten to the gas shovel chisel of commonly adopting, and the chisel is beaten the in-process and easily produces the raise dust environment, causes adverse effect to mining operating personnel's healthy.
For this reason, there is prior art actively dedicated to the development of a technique for reducing the dust emission situation in this environment, and chinese utility model patent with publication number CN 216077195U discloses a dust remover for mining engineering mine, which collects and transfers dust through a dust removing cover provided on an air shovel and sucking air outwards, and does not bring inconvenience to the chiseling operation of the air shovel.
In fact, although the technical scheme can greatly reduce the generation of the raised dust condition, the removal efficiency of the raised dust is difficult to further improve, and the inventor of the present application believes that, on the basis of the prior art, the potential of further improving the removal efficiency of the raised dust through improvement still exists.
Disclosure of Invention
In order to solve the technical problems, the inventor of the application improves and designs the prior art, and aims to provide a dust suppression device for mining, which enhances the effect of suppressing dust.
The object of the invention is illustrated below:
the raise dust suppression device of mining for restrain the raise dust that the operation in-process was beaten to gas shovel chisel, include:
the dust hood is covered on a working area of the shovel chisel and is provided with a hood body gradually expanding along the drilling direction of the shovel chisel;
one end of the dust collection pipeline is communicated with the inner area of the dust collection cover;
the dust collection power source is communicated with the other end of the dust collection pipeline and is used for providing dust collection power;
an arc-shaped connecting part surrounding the shovel drill rod is arranged on the dust collection cover, and one end of the dust collection pipeline is communicated with the inner area of the dust collection cover through the arc-shaped connecting part;
the dust-laden air is sucked into the dust suction pipeline tangentially along the inner contour of the arc-shaped connecting part.
The suction direction of the dust-containing gas is ingeniously set to be the tangential direction of the inner contour of the dust hood, so that a spiral gas path which is approximately distributed along the inner contour of the dust hood is generated, when the dust-containing gas is sucked in the spiral gas path, compared with the prior art, the suction path is more orderly, centrifugal motion which tends to the inner contour of the dust hood is easily formed, dust is more easily guided into the suction gas path of the dust-containing gas under the action of the centrifugal tendency, and the dust absorption efficiency can be improved.
Moreover, the inventor finds that after the dust hood in the prior art is used for a long time, the inner wall of the dust hood is easy to deposit/accumulate a dust layer, the dust layer needs to be cleaned at intervals, and the dust hood is troublesome, and through the improved design, the generated spiral air passage can play a role in flushing the inner contour of the dust hood, so that the generation of the dust layer is inhibited to a great extent, and the use of the dust hood is convenient.
Usually, as also used in the prior art, the cover body of the dust collecting cover is configured as a circular truncated cone structure gradually expanding along the drilling direction of the drill bit, and in this case, the dust collecting cover is often made by integrally molding materials or by integrally molding left and right parts separately.
However, the inventors considered that it is beneficial to increase the collection efficiency of the dust by enlarging the collection range of the dust collection cover for the dust-containing gas, that is, enlarging the collection area of the dust collection cover at the end close to the working area;
meanwhile, the inventors also consider that: the volume of reducing dirty gas in the dust cage that is close to dust absorption pipeline one end region is also profitable, this is because dirty gas is when being close to the dust absorption pipeline gradually, and its volume is by the range of reduction big more, and then the increase range of gas flow speed is also big more, and higher gas flow velocity is favorable to carrying the dust granule, reduces the dispersion of dust granule, promotes the collection efficiency of dust.
For the existing dust hood structure, for a gas shovel with a fixed specification, if the gas collection range of the dust hood is increased, one end of the dust hood close to an operation area is inevitably expanded outwards, and the expanded outwards can cause the synchronous expansion of the volume of the area of dust-containing gas close to one end of a dust collection pipeline; on the contrary, if the volume of the area of the dust-containing gas near one end of the dust absorption pipeline is to be reduced, the dust hood is necessarily retracted, and the collection range of the dust hood for the gas is reduced;
that is, for the conventional dust hood structure, two beneficial operations of "expanding the collection range of the dust hood for the dust-containing gas" and "reducing the volume of the dust-containing gas in the dust hood near one end of the dust suction pipeline" are contradictory and cannot be realized synchronously.
In view of the above problems, the inventor has devised to connect a collecting part and a collecting part of the dust collecting cover, the collecting part and the collecting part being sequentially arranged along the drilling direction of the drill bit, wherein the arc-shaped connecting part is arranged on the collecting part, the collecting part is used for forming a collecting space before the dust-containing gas is sucked into the dust suction pipeline, and the collecting part is used for forming a collecting inlet and a flow space before the dust-containing gas is collected;
the advantage of such an arrangement is that the volume of the collecting part can be made small, independent of the structure of the opening expansion of the collecting part; the opening of the collecting part can be made very large, and is not influenced by the small-volume structure of the collecting part, so long as the structure of the joint of the collecting part and the collecting part is matched.
Further, in order to better amplify the respective advantages and features of the pooling portion and the collecting portion, the inventors have provided a transitional engagement portion between the pooling portion and the collecting portion, such that the transitional engagement portion can engage the pooling portion at a more constricted end and the collecting portion at a more expanded end.
Aiming at the following steps: the two beneficial operations of 'expanding the collection range of the dust-collecting hood on the dust-containing gas' and 'reducing the volume of the dust-containing gas in the dust-collecting hood close to one end of the dust suction pipeline' are conflicting and cannot be realized synchronously, and the inventor provides another solution idea:
the dust hood is characterized in that the dust hood body is arranged to be an arc-shaped expansion structure along the drilling direction of the shovel chisel rod, the arc-shaped expansion structure enables the dust hood body to form an arc-shaped surface compressed towards the inner area of the dust hood, and the dust hood has the advantages that the collection range of the dust hood on dust-containing gas is enlarged, and meanwhile, the relatively small volume of the inner area of the dust hood close to one end of the dust collection pipeline can be obtained through the contraction of the arc-shaped structure.
In order to further improve the suction force on the dust-containing gas, the end part of the dust absorption pipeline communicated with the dust hood is internally provided with a flow increasing part; increase a class portion for one section pipeline that the both ends have carried out the undergauge in the middle part, dust-laden gas gets into the pipeline of undergauge via the one end that increases a class portion after, and gas is compressed-velocity of flow increase, and when again flowing into the other end that increases a class portion by the pipeline of undergauge, volume increase-velocity of flow slow-down can form local negative pressure (pipeline department for undergauge) environment at the other end department that increases a class portion simultaneously, and this local negative pressure environment can assist promotion to dust-laden gas's suction.
In the alternative scheme, the dust collection cover is divided into a left cover body and a right cover body, the left cover body and the right cover body are fixed on the air shovel through a hoop structure, and the left cover body and the right cover body are connected in an embedded mode through tenons and mortise slots; meanwhile, part of the dust absorption pipeline can be detachably and fixedly connected to the air shovel, a certain constraint effect can be formed on the dust absorption pipeline, and construction is facilitated.
In order to prevent dust from entering the dust suction power source, a dust filtering device is arranged between the dust suction pipeline and the dust suction power source.
In summary, the technical scheme of the invention has the following main beneficial effects:
(1) the dust absorption efficiency can be improved, and meanwhile, the enrichment of the lining layer on the inner wall of the dust collection cover is inhibited;
(2) the two beneficial operations of 'expanding the collection range of the dust-collecting hood on the dust-containing gas' and 'reducing the volume of the dust-containing gas in the area of the dust-collecting hood close to one end of the dust suction pipeline' can be synchronously realized.
Further or more specific advantages will be described in the detailed description in connection with the specific embodiments.
