[0028] Furthermore, a limiting bracket 214 is extended from the top of the upper base 21. In this embodiment, four limiting brackets 214 are preferably arranged at intervals. A nozzle 215 is provided in the main body. In this embodiment, the nozzle 215 is preferably an annular structure, and a plurality of spray ports are provided on the nozzle 215. The nozzle 215 is located in the first air duct 211, and one end of the limiting bracket 214 extends into the first air duct 211. The nozzle 215 is fixedly connected to the limiting bracket 214, and the spray port of the nozzle 215 faces the water tank 213. When the air guide cover 1 is covered on the top of the upper base 21, the inner side of the air guide cover 1 is in contact with the limiting bracket 214, thereby increasing the stability of the air guide cover 1 when it is covered on the top of the upper base 21.
[0029] Please refer to Figure 2-Figure 5 .
[0030] A water supply mechanism is provided in the main body, the water supply mechanism is located in the water tank 213, and the water supply mechanism is connected to the nozzle 215; a sink is provided in the water tank 213, and the water supply mechanism includes a water pump 221 and a water supply pipe 222. In this embodiment, four water supply pipes 222 are preferably provided; the water pump 221 is placed in the sink, one end of the water supply pipe 222 is connected to the water pump 221, and the other end of the water supply pipe 222 passes through the water tank 213, and the other end of the water supply pipe 222 extends out of the water tank 213 and is connected to the nozzle 215, and the outer side of the water supply pipe 222 fits the outer side of the limiting bracket 214; a limiting column extends in the sink, and a filter screen 216 is detachably installed on the top of the sink, and the limiting column passes through the filter screen 216. The filter screen 216 is used to filter the water source entering the sink to prevent dust and sand in the water source from clogging the water pump 221;
[0031] Further, a filter barrel 23 is installed in the water tank 213, and a filter box 231 is detachably connected in the filter barrel 23. The filter box 231 is used to filter dust and sand contained in the water source in the filter barrel 23; a plug 232 and a spring 233 are arranged in the filter box 231, and the bottom of the plug 232 is in a cross shape, and the bottom of the plug 232 passes through the filter barrel 23, and the notch of the plug 232 passing through the filter barrel 23 is circular, and the two ends of the spring 233 respectively touch the inner wall of the filter box 231 and the top of the plug 232, and the top of the limit column touches the bottom of the plug 232 to compress the spring 233;
[0032] When the water source sprayed by the nozzle 215 brings dust and sand into the filter barrel 23, the filter box 231 performs the first step of filtering; because the filter barrel 23 is placed in the water tank 213, the top of the limit column hits the bottom of the plug 232 to compress the spring 233, so that the plug 232 opens the gap of the filter barrel 23, allowing the water source filtered in the first step to enter the water tank 213, and the filter screen 216 performs the second step of filtering before the water source enters the trough, so as to prevent the dust and sand in the water source from clogging the water pump 2 21; When too much dust and sand accumulate in the filter barrel 23, the filter barrel 23 is taken out of the water tank 213 for cleaning by disassembling the lower air guide cover 1. When the filter barrel 23 is picked up, the spring 233 pushes the plug 232 to close the gap of the filter barrel 23 to prevent the water in the filter barrel 23 from flowing out of the gap when the worker takes out the filter barrel 23; after cleaning the filter barrel 23, put it back in place, and cover the air guide cover 1 on the upper base 21 to complete the maintenance of the filter barrel 23.
[0033] Furthermore, a plurality of vents 217 arranged at intervals are provided on the top of the upper base 21. In this embodiment, four vents 217 are preferably provided. The vents 217 penetrate the upper base 21, and the middle of the water supply pipe 222 is located between two adjacent vents 217.
[0034] Furthermore, a cavity is formed at the bottom of the upper base 21 , and the vent 217 is connected to the cavity.
[0035] Please refer to Figure 2 and Figure 5 .
[0036] A third air duct is provided in the lower base 24. In this embodiment, the third air duct is preferably an annular structure. A plurality of air outlets 241 are provided on the main body. The plurality of air outlets 241 are arranged at intervals on the outer side of the lower base 24. The air outlets 241 penetrate into the lower base 24 and communicate with the third air duct.
[0037] Furthermore, the lower base 24 is sleeved on the bottom of the upper base 21; a wind mechanism 25 is provided in the main body, the wind inlet area of the wind mechanism 25 is close to the second air duct 212, and the wind outlet area of the wind mechanism 25 is close to the exhaust port 241; the wind mechanism 25 is placed in the lower base 24, the wind inlet area of the wind mechanism 25 is close to the vent 217, and the wind outlet area of the wind mechanism 25 is close to the exhaust port 241;
[0038] Furthermore, the wind power mechanism 25 includes a driving motor 251 and a wind wheel 252. The driving motor 251 is fixedly connected to the top of the lower base 24. The output shaft of the driving motor 251 is fixedly connected to the wind wheel 252. A plurality of fan blades 253 are arranged at intervals on the outside of the wind wheel 252. The air inlet area is located at the top of the fan blade 253, the air outlet area is located at the top of the fan blade 253, and the wind wheel 252 is located in the cavity.
[0039] Please refer to Figure 1-Figure 5 .
[0040] The output shaft of the driving motor 251 drives the wind wheel 252, and the wind wheel 252 generates suction using the fan blades 253, so that the dust outside the main body is sucked into the third air duct by the fan blades 253 from the air inlet 11, the first air duct 211, the second air duct 212 and the vent 217 in sequence; when the dust enters the air inlet 11, the water pump 221 is started, and the water pump 221 sucks water from the water tank 213, and provides water to the nozzle 215 through the four water supply pipes 222, and the water flows out from the spray port of the nozzle 215 After passing through the first air duct 211, the dust finally sprays into the water tank 213. In the process of entering the second air duct 212 from the first air duct 211, the dust will contact the water source. The water source brings the dust and large sand particles in the dust into the filter barrel 23 of the water tank 213, reducing the dust and large sand particles in the dust, thereby converting the dust into air. The air in the second air duct 212 enters the third air duct from the vent 217 under the suction of the fan blade 253. The air is discharged from the exhaust port 241 in the third air duct to the outside of the main body;
[0041] Because the air has been in contact with the water source, the moisture content in the air is high. When the air with high moisture content is mixed into the dust that has not been inhaled by the main body, the moisture makes the dust in the dust heavier and falls, further improving the dust removal efficiency of this equipment.
[0042] The utility model provides a dust removal device for construction engineering. The device is placed on a construction site. A wind mechanism provides kinetic energy to suck dust into a main body. The dust enters a water tank in the main body from an air inlet. A water supply mechanism sucks water into the water tank, supplies water to a nozzle, and the nozzle sprays water from a first air duct into the water tank. The dust contacts the water source during the process of entering the second air duct from the first air duct. Dust and large sand particles in the dust are adsorbed by the water source and driven into the water tank, thereby reducing the dust and large sand particles in the dust and converting them into air. When the air approaches the wind mechanism, the dust and large sand particles have been filtered, thereby preventing the wind mechanism from being blocked by dust and large sand particles.
[0043] Because the air has been in contact with the water source, the air entering the second channel has a high moisture content. Under the push of the wind mechanism, the air in the second channel is discharged from the exhaust port, and the humid air mixes with the unconverted dust in the air, increasing the moisture content in the dust, making the dust in the dust heavier and falling, further improving the dust removal effect of the equipment.
[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit the protection scope of the utility model. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
