Description

Technical Field

[0001] The utility model relates to the technical field of green building environmental protection construction, in particular to a spray type dust suppression device for building construction. Background Art

[0002] At present, in order to reduce air pollution, construction sites generally use spray-type dust reduction devices to carry out dust reduction operations in the construction site area. The areas in the construction site that are prone to dust generation are generally construction work surfaces or roads, especially transport trucks traveling on the road, which cause particularly serious dust. Existing dust suppression devices, such as the utility model patent with application number CN202120854403.8, discloses a spray dust suppression device for construction sites. On the basis of the existing spray dust suppression device for construction sites, a divergence component connected to the nozzle is arranged on the outer circle of the connecting pipe, and then the high-pressure water flow passes through the connecting pipe and enters the divergence component from the nozzle, and the high-pressure water flow can be radially atomized and sprayed out in a circular surface, which can not only suppress the dust in the middle of the road, but also suppress the dust flying high above the road. At the same time, the angle of the device can be changed within a certain range by manually twisting the outer bellows, so as to make adaptive adjustments according to the actual environment of the construction site and obtain better spraying effect. According to the technical solution disclosed therein, when the existing spray dust suppression device is in use, on the one hand, the water mist generated by atomization often loses power quickly after being sprayed, which is not conducive to improving the coverage of the spray dust suppression work. On the other hand, since the above-mentioned spray dust suppression device is a fixed structure, dust suppression blind spots are prone to occur. Utility Model Content

[0026] refer to Figure 1 , Figure 2 as well as Figure 3 As shown, according to the embodiment of the utility model, the spray dust suppression device for construction includes a water tank body 10 and an air duct 20 connected to the water tank body 10, a siphon 11 is arranged in the water tank, one end of the siphon 11 is located below the water surface of the water tank, the other end of the siphon 11 extends into the air duct 20 and is connected to an atomizing nozzle 30 arranged in the air outlet 22 of the air duct 20, a fan 40 is connected to the air inlet 21 of the air duct 20, and the atomizing nozzle 30 is fixedly connected to the air outlet 22 of the air duct 20 through a support frame 50, and a plurality of ventilation holes 51 are opened on the support frame 50.

[0027] During actual use, the fan 40 blows air in the air duct 20 to form a high-speed airflow, thereby forming a negative pressure at the air outlet 22 of the air duct 20. The water pressure in the water tank body 10 plus the negative pressure at the air outlet 22 draws the water in the water tank body 10 out of the siphon 11 and forms water mist after passing through the atomizing nozzle 30, and then is driven by the high-speed airflow to float to a farther distance, thereby having a higher lift.

[0028] In some specific embodiments of the utility model, the following additional technical features may be provided: the top of the water tank body 10 is connected with a water inlet 12, the air duct 20 is provided with a manifold (not shown in the figure) clamping the water inlet 12, and the manifold is respectively connected with the air inlet 21 and the air outlet 22.

The above design can ensure stable air flow.

[0030] In some specific embodiments of the utility model, it may also have the following additional technical features: the ventilation holes 51 in the innermost circle are crescent holes, and the notch direction of the ventilation holes 51 in the innermost circle is the crescent hole toward the central axis of the support frame 50. The design of the crescent hole can make the airflow flow faster when passing through the ventilation holes 51, so that the airflow at this time has a lower airflow, so as to better attract the water in the water tank body 10 to flow out through the siphon 11, and at the same time, the high-speed and low-pressure airflow can bring a higher initial speed to the subsequent atomized water mist. During the spraying process, the relatively low-pressure water mist airflow can attract the relatively high-pressure dust-raising air outside to complete faster condensation and sedimentation.

[0031] Preferably, each ventilation hole 51 is a crescent hole, and the notch direction of each ventilation hole 51 is a crescent hole toward the central axis of the support frame 50 .

[0032] In some specific embodiments of the present invention, the following additional technical features may be provided: the inner diameter of the air duct 20 gradually decreases from the air inlet 21 to the air outlet 22. With this design, the air flow velocity can be further increased.

[0033] In some specific embodiments of the utility model, it may also have the following additional technical features: the spray dust suppression device for construction also includes a shell 60, and the water tank body 10 and the air duct 20 are both connected to the shell 60. Specifically, the water inlet 12 extends out of the shell 60.

[0034] In some specific embodiments of the utility model, it may also have the following additional technical features: the spray dust suppression device for construction also includes a base 70 and a moving wheel 80 connected to the base 70, and the outer shell 60 is fixedly connected to the base 70.

[0035] In some specific embodiments of the utility model, the utility model may also have the following additional technical features: a towing connector 71 is also connected to the base 70. Through the above design, when necessary, a mobile tool such as a tricycle can be connected to the towing connector 71 to drive the spray dust suppression device for construction to move on the construction site, thereby making up for the blind spot of the fixed spray dust suppression device on the construction site.

[0036] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
