Description

Technical Field

[0001] The utility model relates to the technical field of dust removal devices, in particular to a dust removal device for tunnel construction. Background Art

[0002] After the main structure of the tunnel is completed, various infrastructures need to be constructed inside the tunnel. During the construction process, various dusts are easily generated and dispersed in the air. In addition, the space inside the tunnel is small and the air permeability is insufficient, so the dust is difficult to disperse quickly. For this situation, a common practice is to install a separate dust removal device or dust removal vehicle at the construction site, and use the dust removal device to absorb the dust generated by the construction and filter it before discharging it.

[0003] However, the exhaust fans used in common dust removal equipment are very powerful. While performing large-flow dust suction, they will also discharge a corresponding amount of air. This large-flow air can only be discharged into the tunnel. Under the premise that the tunnel itself is small, the discharged air may blow the dust in other places of the tunnel. Therefore, a more reasonable dust removal device can be designed. Utility Model Content

[0004] The utility model aims to provide a dust removal device for tunnel construction, which can not only remove dust effectively but also avoid causing dust to fly in other places of the tunnel.

[0005] The embodiments of the utility model are realized through the following technical scheme: the dust removal device for tunnel construction of the utility model comprises a base plate, a cover body arranged on the base plate, an exhaust fan arranged in the cover body, a dust suction pipe arranged at the air inlet end of the exhaust fan, a filter device connected to the air outlet end of the exhaust fan, and a connecting pipe; the cover body is a hollow structure, and a plurality of exhaust holes are provided on the outer wall of the cover body; one end of the connecting pipe is connected to one end of the filter device away from the exhaust fan, and the other end is connected to the inside of the cover body.

[0006] Furthermore, the connecting pipes are provided in plurality, and the connecting pipes are all used to connect the filtering device and the cover body.

[0007] Furthermore, filter cotton is provided inside the cover body, and the filter cotton is arranged close to the outer wall of the cover body.

[0008] Furthermore, the thickness of the filter cotton is 1-5 mm.

[0009] Furthermore, the filtering device includes a filter box and a plurality of filter plates arranged in the filter box.

[0010] Furthermore, a plurality of through holes are provided on the upper side of the filter box, and the through holes are used for the filter plates to pass through.

[0011] Furthermore, the dust suction tube is a bendable corrugated tube.

[0012] Furthermore, a plurality of universal wheels are provided on the lower side of the base plate.

[0013] Furthermore, the universal wheel is connected to a driving mechanism; the driving mechanism includes a motor connected to the universal wheel.

[0014] The technical solution of the embodiment of the utility model has at least the following advantages and beneficial effects: the dust removal device for tunnel construction of the utility model is directly transported to the place in the tunnel where dust removal is required when in use, and then the exhaust fan is turned on, and the dust suction pipe is aimed at the high-concentration dust area to perform dust suction operations. In this process, the exhaust fan sucks the dust into the filter device for filtration, and the filtered air is discharged through the connecting pipe and the exhaust hole. Since the exhaust holes are opened on all sides of the cover body, the number of exhaust holes is large, the area is large, and the distribution is wide. When the gas is discharged from the exhaust hole, the flow rate is significantly reduced due to the large cross-sectional area of ​​the exhaust. At this time, the exhausted airflow will no longer cause the dust in the tunnel to float. Therefore, the device can not only effectively remove dust at a fixed point, but also effectively avoid the dust dispersion caused by the exhaust fan. BRIEF DESCRIPTION OF THE DRAWINGS

Figure 1 -Attached Figure 4As shown, the dust removal device for tunnel construction in this embodiment includes a base plate 11, a cover body 21 arranged on the base plate 11, an exhaust fan 12 arranged in the cover body 21, a dust suction pipe 13 arranged at the air inlet end of the exhaust fan 12, a filter device connected to the air outlet end of the exhaust fan 12, and a connecting pipe 16; the cover body 21 is a hollow structure, and a plurality of exhaust holes are provided on the outer wall of the cover body 21. One end of the connecting pipe 16 is connected to one end of the filter device away from the exhaust fan 12, and the other end is connected to the inside of the cover body 21. Specifically, when in use, it is directly transported to the place in the tunnel where dust removal is required, and then the exhaust fan 12 is turned on, and the dust suction pipe 13 is aimed at the high-concentration dust area to perform dust suction operations. In this process, the exhaust fan 12 sucks the dust into the filter device for filtration, and the filtered air is discharged through the connecting pipe 16 and the exhaust hole. Since exhaust holes are opened on all sides of the cover body 21, the number of exhaust holes is large, the area is large, and the distribution is wide. When the gas is discharged from the exhaust hole, due to the large cross-sectional area of ​​the exhaust, the flow rate is significantly reduced. At this time, the exhausted airflow will no longer cause the dust in the tunnel to float. Therefore, this device can not only effectively remove dust at a fixed point, but also effectively avoid the dust dispersion caused by the exhaust fan 12.

[0028] In this embodiment, a plurality of connecting pipes 16 are provided, and the plurality of connecting pipes 16 are used to connect the filter device and the housing 21. Specifically, the plurality of connecting pipes 16 can effectively disperse the gas to various positions inside the housing 21.

[0029] In this embodiment, filter cotton 23 is provided inside the cover body 21, and the filter cotton 23 is arranged close to the outer wall of the cover body 21. The thickness of the filter cotton 23 is 1-5 mm. Specifically, the thickness of the filter cotton 23 itself is relatively thin, so it does not mainly play a filtering role, but plays a role in distributing wind, so that the gas can pass through each through hole 22 more evenly, thereby effectively controlling the flow rate of the gas discharged from the through hole 22.

[0030] The filtering device in this embodiment includes a filter box 14 and a plurality of filter plates 15 disposed in the filter box 14. A plurality of through holes 22 are provided on the upper side of the filter box 14, and the through holes 22 are used for the filter plates 15 to pass through. Specifically, the plurality of filter plates 15 are provided to improve the dust filtering efficiency and to facilitate the replacement of the filter plates 15, wherein the through holes 22 can make it more convenient to take out and put in the filter plates 15.

[0031] The dust suction tube 13 in this embodiment is a bendable corrugated tube.

[0032] In this embodiment, a plurality of universal wheels 17 are provided on the lower side of the bottom plate 11. The universal wheels 17 are connected to a driving mechanism; the driving mechanism includes a motor connected to the universal wheels 17. Specifically, the universal wheels 17 and the driving mechanism are provided to make the device more convenient to move.

[0033] In summary, the dust removal device for tunnel construction of this embodiment is directly transported to the place in the tunnel where dust removal is required when in use, and then the exhaust fan 12 is turned on, and the dust suction pipe 13 is aimed at the high-concentration dust area to perform dust suction operations. In this process, the exhaust fan 12 sucks the dust into the filter device for filtration, and the filtered air is discharged through the connecting pipe 16 and the exhaust hole. Since exhaust holes are opened on all sides of the cover body 21, the number of exhaust holes is large, the area is large, and the distribution is wide. When the gas is discharged from the exhaust hole, the flow rate is significantly reduced due to the large cross-sectional area of ​​the exhaust. At this time, the exhausted airflow will no longer cause the dust in the tunnel to float. Therefore, this device can not only effectively remove dust at a fixed point, but also effectively avoid the dust dispersion caused by the exhaust fan 12.

[0034] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations.
