Description

Technical Field

[0001] The utility model belongs to the technical field related to dust reduction spray equipment, and specifically relates to a dust reduction spray device for building construction. Background Art

[0002] Dust reduction spray equipment is a device used to reduce the dust concentration in the air. It is usually used in environments such as construction sites. Its working principle is to transport water or other liquids to the fan outlet through a water pump, and blow the water into the air through wind force to form water mist, thereby adsorbing dust particles in the air on the surface of the water droplets, thereby achieving the effect of dust reduction. However, the nozzle of the existing spray dust reduction equipment is usually surrounded by the inner side or edge of the fan outlet. Since the water spraying direction of the nozzle is uniformly aimed at the fan outlet, the water mist particles collide with each other to form larger water droplets when spraying water outward, which makes it impossible for the wind force of the fan to blow them away. As a result, a large amount of water will drip from under the fan when the dust reduction device is in use, resulting in a waste of water resources. Utility Model Content

[0003] The purpose of the utility model is to provide a dust suppression spray device for construction so as to solve the problem proposed in the above-mentioned background technology that, due to the uniform aiming of the water spraying direction of the nozzle at the air outlet of the fan, the water mist particles collide together to form larger water droplets when spraying water outward, and the wind force of the fan cannot blow them away, resulting in a large amount of water dripping under the fan when the dust suppression device is in use, thereby wasting water resources.

[0006] The arc-shaped collecting trough is connected and fixed to the fan through multiple fixing rods. The arc-shaped collecting trough is used to collect large water droplets dripping from the nozzle. The lower end of the arc-shaped collecting trough is fixedly connected to the upper side of the right end of the water tank through a telescopic hose. The telescopic hose is used to transport the water in the arc-shaped collecting trough into the water tank.

[0007] Preferably, a forced exhaust joint is provided downwardly through the upper end of the inner wall of the arc-shaped collecting tank, and the telescopic hose is screwed and fixed to the outer wall of the forced exhaust joint through a nut to be connected to the arc-shaped collecting tank.

[0014] A large amount of dust will be generated during the construction process on the construction site, which is easy to pollute the air in the city. Dust reduction is usually carried out in places with heavy construction dust on the construction site. The water tank is filled with water. When dust reduction is required, the fan and water pump are connected to the power supply through the switch in the control box. The water pump transports the water in the water tank to the nozzle through the water pipe and sprays water mist through the nozzle.
