DETAILED DESCRIPTION

The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

The utility model provides a dust treatment device for construction engineering, as shown in Figures 1, 2, 3 and 4, the treatment device comprises a treatment box 1, a first chamber opened in the treatment box 1 and containing water and used for filtering air, an exhaust fan 11 arranged at one side of the treatment box 1 for extracting air, a connecting pipe 14 whose two ends are respectively connected with the air outlet end of the exhaust fan 11 and the first chamber, an air outlet pipe 12 arranged on the treatment box 1, a filtering mechanism 3 for filtering water and retaining impurities, a second filter plate 4 fixedly installed in the treatment box 1, an activated carbon adsorption layer 5 fixedly installed in the treatment box 1 and arranged above the second filter plate 4, and a stirring device 2 arranged in the treatment box 1 for accelerating the water flow rate in the first chamber.

The filtering mechanism 3 includes a partition plate 31 fixedly installed in the processing box body 1, a first filter plate 32 fixedly installed on the partition plate 31 and used to separate the inside of the processing box body 1 into a second chamber, and a water pump 33 arranged in the partition plate 31 for pumping water from the second chamber to the first chamber. The first filter plate 32 is provided with a plurality of filter holes for filtering dust in the water.

It should be noted that the top surface of the partition plate 31 has an inclined surface inclined toward the second chamber, and the height of the partition plate 31 close to the first chamber is not lower than the height of the partition plate 31 close to the second chamber.

When it is necessary to use the dust treatment device, clean water is injected into the first chamber through the connecting pipe 14. After the clean water in the first chamber is filled, the clean water is continuously injected. After the clean water level in the second chamber is consistent with the height of the partition plate 31 close to the second chamber, the injection is stopped. The air outlet of the exhaust fan 11 is connected to the connecting pipe 14, and the exhaust fan 11 is started. The outside air is filled into the treatment box 1 through the connecting pipe 14 from the exhaust fan 11. After the air mixed with a large amount of dust is filled with clean water, bubbles appear in the clean water, and the dust in the air is adsorbed by the water to filter the air, so that the air is further kept clean. The dust particles mixed in the air are attracted by the water molecules and float on the water surface due to the surface tension of the air-water interface. The filtered air flows in the direction of the outlet pipe 12 through the impact of subsequent air, and is then filtered by the second filter plate 4 and the activated carbon adsorption layer 5, and then discharged from the outlet pipe 12.

When the clean water in the first chamber is impacted by the air in the connecting pipe 14, the clean water generates fluctuations, so that the dust on the water surface is filtered by the first filter plate 32, and the dust remains between the angle between the top surface of the partition plate 31 and the first filter plate 32. After the clean water is filtered by the first filter plate 32, it falls into the second chamber, and the water pump 33 is started to pump the clean water in the second chamber into the first chamber, so that the clean water can continue to filter the turbid air sent by the connecting pipe 14, thereby improving the filtering effect of the external air.

Furthermore, in order to improve the filtering efficiency of clean water on dust, as shown in Figures 2 and 3, the stirring device 2 includes a stirring rod 21 rotatably installed in the first chamber and a driving motor 22 arranged in the processing box 1 for driving the stirring rod 21 to rotate.

When the air mixed with dust is introduced into the first chamber from the connecting pipe 14, the driving motor 22 is started to drive the stirring rod 21 to rotate, stirring the clean water in the first chamber, increasing the flow rate of the water, and then increasing the contact frequency between the water and the dust particles, thereby improving the dust adsorption efficiency and facilitating use.

Furthermore, in order to facilitate the operator to drain the clean water in the processing box 1 for cleaning, as shown in FIG. 2 , a drain pipe 13 for draining the water in the first chamber and the second chamber is fixedly installed on the processing box 1 .

A check valve is provided on the drain pipe 13 . When the clean water in the processing box 1 needs to be discharged, the check valve is opened to discharge the water in the first chamber and the second chamber from the drain pipe 13 .

It should be noted that, in order to provide installation space for the water pump 33 , as shown in FIG. 4 , a receiving portion is provided inside the partition plate 31 , and the receiving portion is sealed.

The water pump 33 is installed in the accommodating portion, so that the water pump 33 is not easily in contact with water, thereby extending the service life of the water pump 33.

In order to ensure that the air in the connecting pipe 14 is filtered by the clean water, the height of the end of the connecting pipe 14 close to the first chamber is not higher than the height of the side of the partition plate 31 close to the first chamber.

One end of the connecting pipe 14 close to the first chamber is always immersed in water, so that the air is filtered by the water when entering the processing box 1, thereby improving the filtering effect.

The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
