Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of dust prevention in road construction, in particular to a dust reduction device for a construction channel. Background Art
[0002] With the development of the times, people's awareness of environmental protection has been enhanced, and higher environmental protection requirements have been put forward in the construction field. High-dust operations such as earth excavation and transportation, foundation construction, etc. are unavoidable in construction. Dust reduction is particularly important in road construction.
[0003] There are two main dust reduction measures in current construction sites. First, through dust reduction equipment such as fog cannons, but the construction site is complex and changeable, the use of dust reduction equipment is often subject to many restrictions, and the investment in dust reduction equipment and the maintenance of equipment during use will greatly increase the economic cost, which is not very applicable and economical for most construction sites; second, laying out spray pipes on both sides of the construction road, usually arranged around the top of the fence, this type of dust reduction measure greatly reduces the investment in dust reduction equipment.
[0004] In the implementation of the aforementioned dust reduction measures of installing sprinkler pipes on both sides of the construction road, the prior art generally sets a long-distance sprinkler pipe on the top of the enclosure along the extension direction of the enclosure to uniformly supply water, and sets multiple sprinkler ports at intervals on the sprinkler pipe, each sprinkler port is provided with an atomizing nozzle, and provides dust reduction effect through atomizing water spray. The current atomizing water spray has the following problems: when there is wind influence, since the atomizing nozzle is set at the top of the enclosure, it is easily affected by the wind, and in practice, there are problems of poor dust reduction effect and blowing on passers-by outside the enclosure. Utility Model Content
[0005] In order to overcome the problem that the existing spray pipe dust reduction is easily affected by wind force, resulting in poor dust reduction effect, the utility model provides a construction channel dust reduction device which is less affected by wind force and has better dust reduction effect.
[0006] The technical solution adopted by the utility model to solve its technical problems is:
[0007] The dust suppression device for a construction channel comprises an enclosure, a water pump and a water pipe. The water pipe is detachably connected to the enclosure. The water pump is used to transport water to the water pipe. The water pipe comprises a first water pipe fixed at the upper end of the enclosure. The extension direction of the first water pipe is consistent with the extension direction of the enclosure. A spray port is provided on the first water pipe. The water pipe also comprises a second water pipe fixed at the lower end of the enclosure. The second water pipe is arranged parallel to the first water pipe. The second water pipe has a spray port.
[0008] In the present application, a second water pipe is added. Specifically, the second water pipe is fixed at the lower end of the enclosure. Compared with the existing method of only setting the first water pipe, since the second water pipe is set at the lower end of the enclosure, even if the external wind is strong, the impact on the second water pipe in the construction area is small or no impact. At this time, the dust reduction effect is better than that of only setting the first water pipe at the top of the enclosure.
[0009] In some embodiments, a high-pressure flushing flat-mouth nozzle is provided at the spray port on the second water pipe.

[0012] In this embodiment, based on the fact that a high-pressure flushing flat-mouth nozzle has been installed on the aforementioned second water pipe, the spray port at the top, that is, the spray port on the first water pipe, has a lower dust reduction requirement. In order to reduce costs, it is preferably set here as a spray hole opened on the first water pipe. At this time, the liquid particles sprayed from the spray port are larger than those from the atomizing nozzle, and the influence of wind on the liquid particles can also be reduced.

[0014] In this embodiment, the first water pipe is provided with multiple sections, and the first water pipe is connected to the second water pipe through a vertical pipeline, which facilitates the installation and fixation of the first water pipe.

[0016] In this embodiment, a third water pipe is added. The third water pipe is arranged between the first water pipe and the second water pipe. Like the first water pipe, the third water pipe uses a spray hole as a spray port to reduce costs and improve dust reduction effects.
[0017] In some embodiments, the first water pipe and the third water pipe have the same length, their vertical projections overlap, and in the vertical direction, the spray ports on the first water pipe and the third water pipe are staggered.
[0018] In this embodiment, the first water pipe and the third water pipe are preferably of the same length and have overlapping vertical projections for ease of implementation; in the vertical direction, the spray outlets on the first water pipe and the third water pipe are staggered to further enhance the dust reduction effect.
[0019] In some embodiments, each section of the first water pipe is 9-12 m long, and spray ports are provided in the first water pipe and the third water pipe every 1-3 m.
[0020] In this embodiment, the horizontal length of the enclosure commonly used in practice is 2.5-3.5m. Here, the preferred length of the first water pipe is 9-12m. Every 3-5 enclosures correspond to a section of the first water pipe to facilitate the fixed installation of the first water pipe. Spray ports are opened every 1-3m to facilitate effective dust reduction.
[0021] In some embodiments, the vertical pipe is connected to the middle of the first water pipe and the third water pipe.
[0022] In this embodiment, the vertical pipe is connected to the middle of the first water pipe and the third water pipe, so that the overall force is more uniform, which is convenient for installation and avoids deformation or displacement of the branch pipe during operation.
[0023] In some embodiments, the water pipe is a PE water pipe.
[0024] In this embodiment, the water pipe adopts a PE water supply pipe. The PE water supply pipe can withstand the pressure generated during flushing and dust reduction.

[0034] The dust suppression device for the construction channel includes an enclosure 7, a water pump 2 and a water pipe. The water pipe is detachably connected to the enclosure 7.

Even if the external wind is strong, the second water pipe 32 in the construction area is less affected or has no effect. At this time, the dust reduction effect is better than that of only setting the first water pipe 31 at the top of the enclosure 7.
[0036] In the present application, the water pump 2 is a pressure water pump with a power of about 30kw, which provides sufficient water pressure for the first water pipe 31 and the second water pipe 32. The water pump 2 is connected to the tertiary sedimentation tank 1 to provide hydraulic replenishment to the water pipe.
[0037] In this embodiment, a high-pressure flushing flat nozzle 4 is provided at the spray port of the second water pipe 32 for flushing the construction road surface 8, so that dust can be controlled in a lower space.

Based on the fact that the high-pressure flushing flat nozzle 4 has been set on the second water pipe 32, the spray port at the top, that is, the spray port on the first water pipe 31, has a lower dust reduction requirement. In order to reduce costs, it is preferably set as a spray hole 5 opened on the first water pipe 31. At this time, the liquid particles sprayed from the spray port are larger than those from the atomizing nozzle, which can also reduce the impact of wind on the liquid particles.

In the vertical direction, the spray ports on the first water pipe 31 and the third water pipe 33 are staggered. Preferably, the first water pipe 31 and the third water pipe 33 have the same length, and their vertical projections overlap, so as to facilitate implementation; in the vertical direction, the spray ports on the first water pipe 31 and the third water pipe 33 are staggered to further improve the dust reduction effect.
[0043] In this embodiment, each section of the first water pipe 31 is 9-12m long, and spray ports are provided every 1-3m in the first water pipe 31 and the third water pipe 33. In practice, the horizontal length of the enclosure 7 is usually 2.5-3.5m, and here the first water pipe 31 is preferably 9-12m long, and every 3-5 enclosures 7 correspond to a section of the first water pipe 31, so as to facilitate the fixed installation of the first water pipe 31; spray ports are provided every 1-3m to effectively reduce dust.
[0044] In some embodiments, the vertical pipe is connected to the middle of the first water pipe 31 and the third water pipe 33 to make the overall force more uniform, facilitate installation, and avoid deformation or displacement of the branch pipe during operation.
[0045] In this embodiment, the water pipe adopts PE water pipe, which can withstand the pressure generated by flushing and dust reduction. It is a common material on construction sites and can be connected by hot melt. It is simple to maintain in daily use, and it is easy to replace the water pipe when it is damaged. In this embodiment, the second water pipe 32 has a specification of BN50-DN75, and the first water pipe 31 and the third water pipe 33 have a specification of DN20-DN32.
[0046] In some embodiments, a valve is also provided to control the on / off.
