Technical Field
[0001] This utility model relates to the field of environmental dust removal, specifically an environmental dust removal device for building engineering. Background Technology
[0002] Construction projects generate a large amount of suspended particulate matter such as cement dust and stone chips. Traditional dust removal equipment is generally large-area fence-type dust removal and directional dust removal with water cannons. However, in high-dust areas such as mixing plants and cutting areas, direct discharge of spray water is wasteful, and the water left on the ground after wet dust removal makes the ground slippery and muddy, which seriously affects subsequent construction. Therefore, there is an urgent need for an environmental dust removal device for construction projects to solve the above problems. Utility Model Content

[0007] Preferably, a convex water tank is fixedly connected to one end of the dust collector, a transparent top cover is fixedly installed on the top of the convex water tank, and a water injection pipe is fixedly connected to the middle of the top of the transparent top cover.
[0008] Preferably, a perforated groove is provided through the middle of the guide plate, and the filter assembly is located directly below the perforated groove.
[0009] Preferably, the filtration assembly includes a water filter support and a sludge collection box.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] This invention utilizes a negative pressure fan to adsorb dust, which is then condensed by water mist. A nylon water-repellent mesh enhances the condensation and dripping of fine dust and water mist. After purification through a three-stage filtration system, the water is returned to the storage chamber for circulating spraying, achieving water savings of over 90%. The inclined filter design allows sludge to automatically slide into the collection box and be discharged through the drain pipe, reducing water mist directly released into the air and ensuring the dryness of the work area. A corrugated hose allows for flexible operation and coverage, while a baffle effectively prevents water mist backflow. Combined with a transparent cover for visual monitoring of water level and filtration status, this significantly improves dust removal efficiency and ensures continuous construction.

Detailed Implementation
[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figure 1-6 An embodiment of this utility model provides an environmental dust removal device for construction engineering, comprising a dust collection box 1 and a filter assembly 2. The filter assembly 2 is disposed inside the dust collection box 1. Two fans 3 are symmetrically fixedly installed at the top of the dust collection box 1. Two spray pipes 10 are symmetrically fixedly installed at the top of the interior of the dust collection box 1. Atomizing nozzles 11 are uniformly fixedly installed at the bottom of the spray pipes 10. A nylon drain screen 16 is fixedly installed at the top of the interior of the dust collection box 1. A coarse filter screen 17 is fixedly installed inside the dust collection box 1. A guide plate 18 is fixedly installed inside the dust collection box 1 below the coarse filter screen 17.
[0023] Dust collector 1 is fixedly connected to air inlet boxes 6 at both ends. Corrugated hose 7 is fixedly installed at the end of air inlet box 6 away from dust collector 1. Corrugated hose 7 can be connected to dust collector hood to improve dust collection effect. Side plate 4 is fixedly installed on one side of dust collector 1. Water storage chamber 20 is provided at the bottom of the interior of dust collector 1. Water storage chamber 20 is used to hold clean water. Transparent cover plate 5 is fixedly installed on both sides of the top of water storage chamber 20. The transparent cover plate 5 is transparent, so that users can easily observe the internal situation. Water pump 8 is fixedly installed at the top of transparent cover plate 5 near side plate 4. Water inlet pipe 12 is fixedly installed at the input end of water pump 8. The end of water inlet pipe 12 away from water pump 8 is located at the bottom of water storage chamber 20. Branch water pipe 9 is fixedly installed at the output end of water pump 8. The branch end of branch water pipe 9 is fixedly installed on spray pipe 10.
[0024] A convex water tank 13 is fixedly connected to one end of the dust collector 1. A transparent top cover 14 is fixedly installed on the top of the convex water tank 13. The water volume and water quality inside the dust collector 1 can be easily observed through the transparent top cover 14. A water injection pipe 15 is fixedly connected to the middle of the top of the transparent top cover 14. Water is injected into the interior of the dust collector 1 through the water injection pipe 15.
[0025] A trough 19 is provided through the middle of the flow guide plate 18. The filter assembly 2 is located directly below the trough 19. The flow guide plate 18 directs the water flow to the trough 19, and the water flow is discharged downward through the trough 19 to the filter 2 for filtration.
[0026] The filter assembly 2 includes a water filter support 21 and a sludge collection box 22. The inner side of the water filter support 21 is fixedly installed with a first filter layer 23, a second filter layer 24 and a third filter layer 25 respectively from top to bottom. The filter holes of the first filter layer 23, the second filter layer 24 and the third filter layer 25 decrease in size in sequence. The sludge collection box 22 is fixedly installed at the end of the water filter support 21 near the first filter layer 23 that is inclined downwards. The inclined design facilitates the downward flow of filtered sludge impurities into the sludge collection box 22. The filter holes decrease in size in sequence to reduce the filtration pressure of a single filter screen. The water filter support 21 is fixedly installed inside the dust collector box 1.
[0027] A drain pipe 26 is fixedly installed on the bottom outer side of the sludge collection box 22, and the drain pipe 26 passes through the side wall of the dust collector 1 and is located on the outside of the dust collector 1. The drain pipe 26 is installed after the sludge collection box 22 is installed. When there is too much sludge collected inside the sludge collection box 22, it is discharged through the drain pipe 26.
[0028] The dust collection box 1 has baffles 27 fixedly connected to both ends of the inner side. The baffles 27 are located above the air intake box 6. The baffles 27 are used to block the water mist sprayed by the atomizing nozzle 11 to prevent the water mist from spraying into the interior of the air intake box 6.
[0029] Working Principle: During operation, the fan 3 and water pump 8 are first started. The end of the corrugated hose 7 furthest from the air inlet box 6 is placed in the dust-generating area by external force. The start of the fan 3 discharges air from inside the dust collector 1, reducing the air pressure inside. External air enters the dust collector 1 through the corrugated hose 7 and air inlet box 6. Dust-laden air enters the air inlet box 6 through the corrugated hose 7 and is then introduced into the dust collector 1. The water pump 8 draws water from the water storage chamber 20 and delivers it through the water inlet pipe 12 to the branch water pipe 9, which then distributes it to the symmetrically arranged spray pipes 10. Water mist is sprayed downwards from the atomizing nozzles 11, wetting and increasing the weight of the fine dust particles. The larger particles are then intercepted by the coarse filter screen 17. Particulate impurities and dust-laden airflow impact the nylon drain net 16, causing water droplets to condense and flow downwards in the V-shaped path formed by the guide plate 18. Wastewater falls downwards through the trough 19 in the middle of the guide plate 18 and into the three-stage filtration assembly 2. It flows sequentially through the first filter layer 23, the second filter layer 24, and the third filter layer 25 installed at an incline within the water filter support 21. The intercepted sludge slides down the slope into the sludge collection box 22, and the filtered clean water flows back to the water storage chamber 20 for recycling. The sludge is periodically discharged through the drain pipe 26 at the bottom of the collection box, and the purified air is drawn out by the fans 3 installed symmetrically at the top, realizing air-water synergistic dust removal and closed-loop utilization of water resources.
