Description

Technical Field

[0001] The invention relates to the technical field of wet dust removal, and in particular to a wet dust removal device and a dust removal method for construction engineering. Background Art

[0002] During the construction of construction projects, high-temperature production and construction sites will generate a large amount of dust and powder, making the air turbid. Once it enters the mouth and nose of the construction workers, it will cause damage to the workers' throat and lungs, which is not conducive to the continued work of the construction project. Therefore, a dust removal device is needed to purify the dust in the air.

[0003] According to the patent application number CN202021625058.2, by starting the two inlet fans to work at the same time, the air mixed with dust from the outside can be sucked into the dust removal box, and the water pump is started at the same time, and the water in the water tank is injected into the connecting pipe through the water pipe through the water pump pipe, and then atomized and sprayed out by the atomizing nozzle through the spray pipe, so that the dust in the air in the dust removal box can be atomized and sprayed for dust removal, and the silt water with dust falls into the silt box due to gravity, and the silt and sand are precipitated. The purified air is discharged through the exhaust pipe, with good dust removal effect, simple structural design and convenient maintenance. By setting a filtering device, when the water level in the silt box exceeds the height of the filter tank, the water automatically flows into the filter tank, and then through the double filtration of the silt filter screen and the activated carbon filter screen, the water can be purified and returned to the water tank for recycling, which saves more water resources.

[0004] In the above patent, the spray water is not filtered. In some special places, there are many impurities in the water. If it is transported to the atomizing nozzle without treatment, it is very easy to get clogged. Some devices use filter cotton to filter out impurities, but they need to be frequently replaced and cleaned, which is very inconvenient. It is difficult to achieve a continuous supply of atomized water, which reduces the efficiency of subsequent wet dust removal. Therefore, in view of the above shortcomings, the present invention makes the following improvements. Summary of the invention

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Embodiment 1

[0032] See also Figures 1 to 3 As shown, the present invention provides a technical solution, and the specific improvements are as follows:

[0033] A wet dust removal device for construction engineering, comprising a base plate, a dust removal cylinder 1, and a water inlet cylinder 2 fixedly arranged on the top surface of the base plate through a support plate, a permeation plate 21 is fixedly arranged at the bottom of the inner wall of the dust removal cylinder 1, one side of the surface of the dust removal cylinder 1 is respectively connected with an air inlet pipe 22 and a drain pipe 23, a rotating disk 3 is rotatably arranged inside the water inlet cylinder 2, and a sealing gasket is arranged on the surface of the rotating disk 3, a first motor 57 is fixedly arranged on one side of the surface of the water inlet cylinder 2 through a support frame, and one end of the output shaft of the first motor 57 is fixedly connected to the surface of the rotating disk 3 through a coupling, a water inlet groove 4 is opened on the surface of the rotating disk 3, a water inlet pipe 6 is connected to the front of the water inlet cylinder 2, and the other side of the surface of the water inlet cylinder 2 is connected to the water inlet pipe 6. There is an inclined tube 7, a drainage groove 20 is provided inside the rotating disk 3 and on one side of the water inlet groove 4, a water inlet control mechanism 5 is provided inside the water inlet groove 4, and the water inlet control mechanism 5 includes a circular plate 51 fixedly provided inside the water inlet groove 4, and a filter plate 53 is provided on the top surface of the circular plate 51 through a telescopic sleeve 52, a through groove is provided inside the circular plate 51, a pressing block 54 is fixedly provided on one side of the filter plate 53 close to the circular plate 51, a pressure switch 55 is provided on the top surface of the circular plate 51, a buffer spring 56 is fixedly provided between the filter plate 53 and the side opposite to the circular plate 51, and the buffer spring 56, the pressure switch 55 and the pressing block 54 are all located inside the telescopic sleeve 52;

[0034] The spray water is delivered to the current corresponding water inlet trough 4 through the water inlet pipe 6.
