Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to an environment-friendly dust reduction device for construction engineering. Background Art

[0002] At present, during building construction, the floating dust generated by the execution of construction steps such as hammering, chiseling, and painting will affect the physical health of construction workers and also cause environmental noise pollution. Therefore, a dust reduction device is needed.

[0003] The existing dust reduction devices generally use the method of sprinkling water, so that the water contacts the dust in the air and achieves the effect of dust reduction. However, it is found in the actual use process that the water after spray dust reduction directly falls on the ground, and the water cannot be collected, treated, and reused, resulting in waste of water resources and lack of energy conservation and environmental protection. For this reason, an environment-friendly dust reduction device for construction engineering is proposed. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the problems raised in the background art in the prior art, and to propose an environment-friendly dust reduction device for construction engineering.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] An environment-friendly dust reduction device for construction engineering, including a water tank, a suction air pipe is fixedly arranged at the top of the water tank, a suction fan is fixedly arranged inside the suction air pipe, a plurality of support rods are fixedly arranged around the upper end of the suction air pipe, the upper ends of the plurality of support rods are fixedly provided with the same support seat, an electric push rod is fixedly arranged on the top of the support seat, a spray plate is fixedly arranged at the moving end of the electric push rod, the spray plate adopts a hollow structure, and a plurality of spray holes are opened on the lower surface of the spray plate. A pump body is fixedly arranged at the bottom of the water tank, a water lifting pipe extending outward is fixedly arranged at the output end of the pump body, and the end of the water lifting pipe is fixedly connected with the lower surface of the spray plate; an annular opening is arranged at the top of the water tank and outside the suction air pipe, and an annular filter screen is fixedly arranged inside the annular opening. A water receiving hopper is fixedly arranged at the top of the water tank and outside the annular opening.

[0007] Preferably, a partition plate is fixedly arranged in the middle of the water tank. The upper part of the partition plate is a purified water area, and the lower part of the partition plate is a water return area.

[0008] Preferably, a drain pipe is fixedly arranged in the middle of the partition plate, and a solenoid valve is arranged on the pipe wall of the drain pipe.

[0009] Preferably, the pipe wall of the water lifting pipe passes through the inside of the water receiving hopper.

[0010] Preferably, two reinforcing rods are symmetrically and fixedly arranged inside the annular opening, and the annular filter net is fixedly arranged between the reinforcing rods and the annular opening.

[0011] Preferably, a circular filter net is fixedly arranged inside the upper end of the air suction pipe.

[0012] Preferably, the size of the water receiving hopper is larger than that of the spraying plate.

[0013] Compared with the prior art, the utility model provides an environment-friendly dust reduction device for construction engineering, which has the following beneficial effects:

[0014] For the environment-friendly dust reduction device for construction engineering, through the arranged water tank, air suction pipe, suction fan, spraying plate, pump body, water lifting pipe and water receiving hopper, when the pump body works, the water inside the water tank can be pumped into the inside of the lifting pipe, then discharged into the inside of the spraying plate along the lifting pipe, and finally evenly sprayed out through the spraying holes on the spraying plate to form a water curtain, so that the water contacts with the dust in the air and plays a role in dust reduction. At the same time, when the suction fan works, the dust in the surrounding air is sucked into the inside of the air suction pipe and passes through the water curtain, so as to be able to carry out large-area dust reduction treatment. The gas inside the air suction pipe then enters the inside of the water tank and is then discharged outwards through the annular opening. During this process, the air will contact with the water, which can also play a role in dust reduction. The dust water after dust reduction will fall into the inside of the water receiving hopper and flow along the inclined surface inside the water receiving hopper to the inside of the annular opening. The large-particle impurities in the dust water can be filtered out through the annular filter net, and then collected on the upper surface of the partition plate inside the water tank and left to stand. Finally, the operator can add purification reagents to the dust water through the annular opening for purification treatment. After the dust water is treated clean, it is discharged downward and can be recycled.

[0015] The parts not involved in the device are the same as or can be implemented by the prior art. The utility model can not only carry out large-area dust reduction operations, but also automatically collect the dust water after dust reduction and recycle it after purification treatment, meeting the requirements of energy conservation and environmental protection.

At this time, the circular filter screen 18 can filter impurities in the gas. A plurality of support rods 4 are fixedly arranged around the upper end of the suction air pipe 2. The upper ends of the plurality of support rods 4 are fixedly provided with the same support seat 5. The support rods 4 can separate the gap between the suction air pipe 2 and the support seat 5 to ensure that the upper end of the suction air pipe 2 can suck gas. An electric push rod 6 is fixedly arranged on the top of the support seat 5. The moving end of the electric push rod 6 is fixedly provided with a spray plate 7. The spray plate 7 adopts a hollow structure, and a plurality of spray holes 8 are opened on the lower surface of the spray plate 7. If it is necessary to adjust the use height of the spray plate 7, only need to control the telescopic action of the electric push rod 6 to meet the use requirements of different construction sites. A pump body 9 is fixedly arranged at the bottom of the water tank 1. The output end of the pump body 9 is fixedly provided with a water lifting pipe 10 extending outwards, and the end of the water lifting pipe 10 is fixedly connected to the lower surface of the spray plate 7. When the pump body 9 works, it can pump the water inside the water tank 1 into the inside of the lifting pipe 10, and then discharge it into the inside of the spray plate 7 along the lifting pipe 10. Finally, it is evenly sprayed out through the spray holes 8 on the spray plate 7 to form a water curtain, so that the water contacts the dust in the air and plays a role in dust reduction. At the same time, when the suction fan 3 works, the dust in the surrounding air is sucked towards the inside of the suction air pipe 2 and passes through the water curtain, so that large-area dust reduction treatment can be carried out. The gas inside the suction air pipe 2 then enters the inside of the water tank 1. During this process, the air contacts the water and can also play a role in dust reduction.

[0023] Refer to Figure 1 and 3, at the top of the water tank 1 and around the air suction pipe 2, there is an annular opening 11. The annular opening 11 not only serves as a dust and water collection port but also as an exhaust port for the internal gas in the water tank 1 to be discharged outward. And inside the annular opening 11, there is an annular filter screen 12 fixedly arranged. Symmetrically and fixedly arranged inside the annular opening 11 are two reinforcing rods 17. The annular filter screen 12 is fixedly arranged between the reinforcing rods 17 and the annular opening 11. The reinforcing rods 17 can increase the structural strength of the annular opening 11 and ensure the structural strength of the air suction pipe 2 at the top of the water tank 1. At the top of the water tank 1 and around the annular opening 11, there is a water receiving hopper 13 fixedly arranged. The size of the water receiving hopper 13 is larger than that of the spray plate 7. The pipe wall of the water lifting pipe 10 passes through the inside of the water receiving hopper 13; in the middle of the water tank 1, there is a partition plate 14 fixedly arranged. Above the partition plate 14 is the purified water area, and below the partition plate 14 is the water return area. In the middle of the partition plate 14, there is a drain pipe 15 fixedly arranged, and an electromagnetic valve 16 is arranged on the pipe wall of the drain pipe 15; the dust-laden water after dust reduction will fall inside the water receiving hopper 13 and flow along the inclined surface inside the water receiving hopper 13 to the inside of the annular opening 11. The large-particle impurities in the dust-laden water can be filtered out through the annular filter screen 12, and then collected on the upper surface of the partition plate 14 inside the water tank 1 and left for static treatment. Finally, the operator can add purification reagents to the dust-laden water through the annular opening 11 for purification treatment. After the dust-laden water is treated clean, the electromagnetic valve 16 is opened, so that the purified water is discharged downward through the drain pipe 15 and can be circulated and discharged for use through the pump body 9.
