Description

Technical Field

[0001] The present invention relates to the technical field of building construction, in particular to environmentally friendly building construction equipment. Background Art

[0002] The characteristics of the construction environment usually include open-air operations, high-altitude operations, and cross-operation. These factors cause a large amount of dust to be generated at the construction site. In order to improve the construction environment, protect the health of workers, and reduce air pollution, various dust collection equipment are usually used at the construction site for dust removal. At the construction site, appropriate dust removal equipment should be selected according to the actual situation. For areas with large amounts of dust generated, such as excavation and crushing, wet dust collectors or spray dust removal equipment can be considered. For occasions that require high-efficiency dust removal and have high requirements for dust removal effects, such as interior decoration, electrostatic dust collectors or dry dust collectors can be considered.

The equipment comprises a vehicle body, a spray device disposed above and connected to the vehicle body for spraying water mist, and a suction device disposed below the vehicle body for sucking waste dust. The suction device includes a suction mechanism for sucking waste dust adhering to the ground, a suction assembly, and a micro-drying assembly for accelerating the drying of the waste dust on the ground so that it can be sucked away. The suction assembly includes a suction pipe, a suction pump, and a dust collection box.

Each atomizing nozzle 20 is located directly above the rainproof cloth 15, and the atomization range of the atomizing nozzle 20 is smaller than the unfolded area of ​​the rainproof cloth 15, ensuring that the atomized dust clusters can be collected by the rainproof cloth 15.

[0037] Working principle: When using the device to handle dust, the worker moves the vehicle body 1 to the corresponding position, drives the lifting assembly to lift the height of the circular body 2, and then starts the second electric push rod 34 installed in the second accommodating sleeve 24 to drive the retraction column 25 to move horizontally, thereby driving the second annular body 4 to adjust horizontally, thereby adjusting the position of the rainproof cloth 15 to ensure that there is enough space for the rainproof cloth 15 to unfold. Then, the first motor 11 is driven to drive the screw rod 8 to rotate, and the rotation of the screw rod 8 drives the threaded plate 9 to move vertically in the rectangular hole 7, thereby driving the first annular body 10 to move up and down, and the keel 12 and the push rod 1 are driven by the first annular body 10. 3. The tarpaulin 15 is unfolded, and at the same time, the water pump 22 is started to bring the clean water in the water storage tank 21 into the circular water tank 19 through the water supply hose 38. The water is then introduced into each atomizing nozzle 20 through the metal pipe 37 installed on the circular water tank 19. The atomizing nozzle 20 sprays the water into atomized form to suppress dust. Each atomizing nozzle 20 is located directly above the tarpaulin 15.
