Description

Technical Field

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

[0002] Building construction refers to production activities during the implementation phase of engineering construction. It is the construction process of various types of buildings. It can also be said to be the process of turning various lines on the design drawings into physical objects at designated locations. It includes foundation engineering construction, main structure construction, roofing engineering construction, decoration engineering construction, etc. A large amount of dust will be generated at the construction site due to the flow of vehicles and material transfer. Dust pollution to the air cannot be avoided. Therefore, dust removal equipment is required to deal with the dust generated during the construction process of the construction site.

[0003] According to the existing authorization publication number CN215027295U, an environmentally friendly dust removal device for construction sites comprises a cart, wherein a water tank is fixedly connected to one side of the upper surface of the cart, a water pump is fixedly connected to the top of the water tank, one end of the water pump away from the water tank is fixedly connected to a drain pipe, and one end of the drain pipe away from the water pump is fixedly connected to a cleaning box, the bottom of the cleaning box is fixedly connected to the other side of the upper surface of the cart, one side of the cleaning box is fixedly connected to an air inlet pipe, the inner wall of the air inlet pipe away from the cleaning box is fixedly connected to a first dust filter net, a first fan is installed on the side of the inner wall of the air inlet pipe close to the cleaning box, the inner top wall of the cleaning box is fixedly connected to the water inlet pipe, one end of the drain pipe away from the water pump penetrates and is fixed to the outer wall of the cleaning box and is connected to the outer side surface of the water inlet pipe, and a plurality of nozzles are fixedly connected to the lower surface of the drain pipe at intervals. This device can effectively absorb dust particles, has a good dust removal effect, and protects the environment. During use, this dust removal device first collects the dust into the inside of the cleaning box, and finally uses atomization dust reduction to remove the dust. However, the sewage after the dust reduction is used is directly collected into the collection box, and the sewage cannot be recycled after use, which will cause a waste of water resources. At the same time, the height and angle of the dust removal air inlet pipe are fixed, which is inconvenient during use. Therefore, we propose an environmentally friendly dust removal device for construction sites to solve the above problems. Utility Model Content
