Both types of vehicles are large, and the working environment requires a flat road surface. For some special situations, there is not enough space to arrange the sprinkler truck and atomizer truck to work. Therefore, the present invention provides a self-made small-sized pushable dust reduction device. Summary of the invention

[0020] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be further described in detail below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention but not all. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0021] like Figure 1-2 , a dust suppression device for environmental protection engineering provided in this embodiment includes a dust collection box 11 with a moving wheel 10 at the bottom, and a spray box 12 is provided on the top of the dust collection box 11;

[0022] A filter 13 is provided inside the dust box 11, and an air inlet pipe 14 and an air outlet pipe 15 are provided on the side wall of the dust box 11. The air inlet pipe 14 is located below the air outlet pipe 15, and a suction fan 16 is provided on the air inlet pipe 14. The suction fan 16 sucks air into the air inlet pipe 14 and discharges it through the air outlet pipe 15, passing through the filter 13 in the middle.

[0023] The side wall of the spray box 12 is provided with a plurality of spray pipe openings 17 , and external water 26 is sprayed out from the spray pipe openings 17 by a pump 18 provided inside the spray box 12 to reduce dust.

[0024] The front end of the air inlet pipe 14 is configured as a bent pipe 19 with the pipe opening facing downward, and the air inlet is directed downward to the ground, so as to absorb dust on the ground.

[0025] It should be noted that in the present invention, a handle 22 is provided on the dust box 11 for pushing the overall movement of the device. At the same time, a window 23 is provided on the top of the dust box 11 for operating and replacing the filter 13.

[0026] The spray pipe opening 17 is located on the same side as the air outlet pipe 15. The air outlet pipe 15 is provided with one, and the spray pipe openings 17 are provided in multiple groups, and one of the spray pipe openings 17 on the same side corresponds to the air outlet pipe 15 up and down.

[0027] In the above structure, the suction fan 16 is turned on, and the suction fan 16 sucks air from the air inlet pipe 14 and discharges it from the air outlet pipe 15. The air passes through the filter 13 in the middle, and the adsorbed dust is partially filtered on the filter 13. The air discharged by the air outlet pipe 15 has less dust, which plays a role in partially raising dust on the ground. The spraying part is located above the dust suction, and the dust is filtered during the dust suction. The exhaust of the dust suction will spread the water mist sprayed by the spraying farther, increase the spraying distance, and realize close-range dust suction and long-range spraying. The spraying part also directly sandblasts at close range to achieve full-distance coverage.

[0028] The filter 13 divides the dust collecting box 11 into two parts, and is used to isolate the air on both sides. The air must pass through the filter 13 to reduce the dust from being blown out from the air outlet pipe 15 again.

[0029] The present invention also fills the dust box 11 with water, the water level covers the filter 13, the air inlet pipe 14 extends upward into the dust box 11, and then extends downward to below the water level after reaching the top of the dust box 11, forming an N-shape as a whole, and the air outlet pipe 15 is located above the water level.

[0030] The air inlet pipe mouth points to the water, and dust will fall into the water, and the water can be mixed with the dust to reduce the dust flying inside. At the same time, the air inlet pipe 14 is generally N-shaped, which prevents the water inside the dust box 11 from flowing back out from the air inlet pipe 14.

[0031] A baffle 21 with a plurality of water-permeable holes is provided at the outlet of the air inlet pipe 14 below the water level inside the dust box 11. The outlet part of the air inlet pipe is divided into a plurality of air passages to disperse dust and avoid dust concentration, thereby increasing the contact area with the water surface and facilitating mixing with water.

[0032] The dust box 11 is provided with a water inlet pipe 24 and a water outlet pipe 25. One end of the water inlet pipe 24 is connected to the external water 26, and the other end is connected to the inside of the dust box 11 on the side where the air inlet pipe 14 is provided, and is located above the water level. The water outlet pipe 25 is connected to the inside of the dust box 11 on the side where the air outlet pipe 15 is provided, and is located below the water level. The water outlet of the water outlet pipe 25 is connected to the pump 18 inside the spray box 12.

[0033] The water filled in the dust box 11 on the side of the air outlet pipe 15 is relatively clean after being filtered by the filter 13, and is sucked by the pump 18 to the spray pipe for spraying. In the process of pumping water, the turbid water in the dust box 11 on the side of the air inlet pipe 14 continuously flows through the filter 13 and the dust box 11 on the side of the air outlet pipe 15, and the dust is intercepted on the side of the filter 13, and the turbid water in the dust box 11 on the side of the air inlet pipe 14 is continuously reduced, and the dust is adsorbed on the filter, which is convenient for unified cleaning, and then the water is discharged from the water inlet pipe 24. The water inlet and outlet can be opened synchronously to achieve uninterrupted operation.
