[0002] During construction work, construction processes such as earth excavation, material cutting, and concrete mixing generate a large amount of dust. At the same time, the working environment is often closed or poorly ventilated, leading to dust accumulation. These dusts not only pollute the air, but also harm the health of construction workers (such as causing respiratory diseases), and even affect construction efficiency and equipment life.

[0003] Patent No. CN209221758U discloses a building ventilation and dust removal device. The dust in the building is collected by the dust removal device at the back of the air suction device, reducing the dust content in the building and achieving dust removal effect. The dust is brought into the dust removal device by the action of the air suction device, and is sprayed by the water in the water falling tray. The dust adheres to the water under the action of gravity and falls into the water storage box, achieving dust removal operation. The device has the advantages of convenient ventilation and dust removal.

[0021] The separating device comprises a water storage tank 71, a motor 72, a reciprocating screw rod 73, a moving plate 74, a spiral groove rod 75, a cam 76, a moving block 77, a return spring 78, a spoiler 79, a pressing plate 710, a watering tank 711, a supporting rod 712 and a sealing plate 713. The water storage tank 71 penetrates the bottom surface of the box body 1 and is slidingly connected at the penetration position. The motor 72 is fixedly connected to the upper surface of the inner wall of the box body 1. The output end of the motor 72 is fixedly connected with a rotating shaft. When the motor 72 is started, the rotating shaft is driven to rotate. The reciprocating screw rod 73 is fixedly connected to the end of the rotating shaft away from the motor 72. The rotating shaft drives the reciprocating screw rod 73 at the bottom end to rotate. The reciprocating screw rod 73 penetrates the moving plate 74 and is slidingly connected at the penetration position. The spiral groove rod 75 penetrates the two ends of the moving plate 74 and is slidingly connected at the penetration position. The spiral groove rod 75 penetrates the bottom surface of the water storage tank 71 and is rotationally connected at the penetration position. When the reciprocating screw rod 73 rotates, the moving plate 74 is slidingly driven by the reciprocating screw rod 73 to move up and down because the two ends of the moving plate 74 are fixedly connected with the spiral groove rod 75 and cannot rotate. When the moving plate 74 moves up and down, the spiral groove rod 75 penetrating the two ends of the moving plate 74 is driven to rotate. The spiral groove rod 75 penetrates the cam 76 and is fixedly connected at the penetration position. When the spiral groove rod 75 rotates, the cam 76 is driven to rotate. The bottom surface of the cam 76 is attached to the bottom surface of the inner wall of the water storage tank 71. The moving block 77 is slidingly connected to the bottom surface of the inner wall of the water storage tank 71. When the cam 76 rotates to the position of the moving block 77, the cam 76 drives the moving block 77 to slide away from the cam 76. One end of the return spring 78 is fixedly connected to the end of the moving block 77 away from the cam 76. The other end of the return spring 78 is fixedly connected to the inner wall of the water storage tank 71. When the moving block 77 slides, the return spring 78 is pressed. The spoiler 79 is fixedly connected to the upper surface of the moving block 77. When the moving block 77 slides, the spoiler 79 is also driven to move. When the spoiler 79 moves, the water in the water storage tank 71 is stirred. The pressing plate 710 is slidingly connected to the inner wall of the water storage tank 71. When the spoiler 79 slides away from the cam 76 to the position of the pressing plate 710, the pressing plate 710 is driven to slide upward. The watering tank 711 is fixedly connected to the side wall of the pressing plate 710. The watering tank 711 is slidingly connected to the inner wall of the water storage tank 71. When the pressing plate 710 slides upward, the watering tank 711 is also driven to slide upward. The upper surface of the watering tank 711 is provided with a through hole. The water flowing into the watering tank 711 from the through hole in the upper surface of the watering tank 711 is the water flowing into the watering tank 711 from the through hole in the upper surface of the watering tank 711. The supporting rod 712 is fixedly connected to the bottom surface of the inner wall of the water storage tank 71. The supporting rod 712 penetrates the bottom surface of the watering tank 711 and is slidingly connected at the penetration position. The sealing plate 713 is fixedly connected to the upper surface of the supporting rod 712. The side wall of the sealing plate 713 is attached to the inner wall of the watering tank 711. When the watering tank 711 slides downward, the water in the watering tank 711 is pressed by the sealing plate 713 and sprayed from the through hole.The reciprocating screw rod 73 and the helical slot rod 75 drive the moving plate 74 to move up and down in cooperation with the motor 72, so as to mix the indoor and outdoor air, avoid the indoor environment being relatively closed, and the oxygen content in the indoor air being insufficient after long-term work in the indoor environment. After the air is mixed, the spoiler 79 is repeatedly moved in cooperation with the cam 76, the moving block 77 and the return spring 78, so as to avoid the dust in the water tank 71 from depositing at the bottom after being static, and the dust saturation in the dust-settling water at the bottom being high, which affects the adsorption of the dust-settling water to the dust in the air. The problem that the oxygen content in the air is insufficient after long-term work in the indoor environment, and the dust saturation in part of the dust-settling water is high, which leads to low dust separation efficiency, is solved. When the air in the box 1 is dust-settled, the clean dust-settling water is sprayed out in the form of small water mist in cooperation with the pressing plate 710, the water spraying tank 711, the supporting rod 712 and the sealing plate 713, so that the dust-settling water can be dispersed in the box 1, the dust-settling efficiency of the dust-settling water to the air in the box 1 is further improved, the separation effect of the dust in the air is improved, and the problem that the air in the box 1 may directly overflow at the air inlet 4, which leads to poor dust-settling effect in the indoor environment, is solved.

[0022] When the present embodiment works: the air in the indoor environment is sucked from the air inlet 4 and mixed with the outdoor air entering the ventilation duct 3 by starting the fan, the water inlet pipe 6 is connected to the water source to supply water to the box 1, and the air is blown out from the air outlet 5 after dust-settling treatment by the operation of the fan.

[0023] The motor 72 is started, the motor 72 drives the rotating shaft to rotate, the rotating shaft drives the reciprocating screw rod 73 at the bottom to rotate, when the reciprocating screw rod 73 rotates, because the moving plate 74 is slidingly connected with the reciprocating screw rod 73, and the both ends are penetrated by the spiral groove rod 75 and cannot rotate, when the reciprocating screw rod 73 rotates, the moving plate 74 is driven to slide up and down, when the moving plate 74 slides up and down, the spiral groove rod 75 penetrating the both ends is driven to rotate, when the spiral groove rod 75 rotates, the cam 76 is driven to rotate, when the cam 76 rotates to the moving block 77, the side wall of the cam 76 and the side wall of the moving block 77 slide with each other, the cam 76 pushes the moving block 77 to slide away from the cam 76, when the moving block 77 slides, the return spring 78 is extruded, when the moving block 77 slides, the spoiler 79 is also driven to move, when the spoiler 79 moves, the water in the water storage tank 71 is stirred, when the spoiler 79 slides away from the cam 76 to the extrusion plate 710, the oblique edge of the spoiler 79 and the inclined surface of the extrusion plate 710 slide with each other, the spoiler 79 pushes the extrusion plate 710 to slide upward, when the extrusion plate 710 slides upward, the watering tank 711 is also driven to slide upward, the water flowing from the water inlet pipe 6 flows into the watering tank 711, when the cam 76 rotates to separate from the moving block 77, the moving block 77 is reset by the restoring force of the return spring 78, when the moving block 77 is reset, the spoiler 79 is also reset, the extrusion plate 710 is no longer pushed by the spoiler 79, and the watering tank 711 contains a large amount of water and is subjected to a large gravity, so the extrusion plate 710 is driven to slide downward, and the inner wall of the watering tank 711 and the outer wall of the sealing plate 713 are in close contact, so the water in the watering tank 711 is extruded by the sealing plate 713 and sprayed from the hole when the watering tank 711 descends.

[0024] Please refer to Figures 1-7On the basis of the above embodiment, in another embodiment of the application, the inside of the box body 1 is provided with a dismounting device for conveniently processing the separated dust, the dismounting device comprises a fixed block 81, a fixed rod 82, a limiting rod 83, a limiting spring 84, a limiting block 85 and a partition plate 86, the fixed block 81 is fixedly connected to the bottom surface of the water storage tank 71, the fixed rod 82 is fixedly connected to the bottom surface of the box body 1, the limiting rod 83 penetrates through the fixed rod 82 and is slidingly connected at the penetration position, when the water amount in the water storage tank 71 is too much, the limiting rod 83 is pushed towards the fixed rod 82, one end of the limiting spring 84 is fixedly connected to the inner wall of the fixed rod 82, the other end of the limiting spring 84 is fixedly connected to the side wall of the limiting rod 83, the limiting rod 83 slides to compress the limiting spring 84, the limiting block 85 is fixedly connected to the end of the limiting rod 83 away from the limiting spring 84, the limiting rod 83 drives the limiting block 85 to slide, when the limiting block 85 slides to be separated from the fixed block 81, the limiting of the water storage tank 71 is released, the water storage tank 71 can be pulled out downwards, the partition plate 86 is fixedly connected to the inner wall of the box body 1, the inner wall of the partition plate 86 is attached to the side wall of the water storage tank 71, after the water is sprayed out of the through hole and falls into the water storage tank 71, when the water amount in the water storage tank 71 reaches a certain amount, the dust-settling water cooperates with the partition plate 86 to separate the ventilation duct 3, the air inlet 4 and the air outlet 5, the air circulation from the air inlet 4 to the air outlet 5 needs to pass through the dust-settling water in the water storage tank 71, at this time, the swing of the spoiler 79 promotes the fusion of the air and the dust-settling water, the limiting of the water storage tank 71 by the dismounting device cooperating with the fixed block 81, the fixed rod 82, the limiting rod 83, the limiting spring 84 and the limiting block 85 makes the water storage tank 71 more convenient to install and dismount from the inside of the box body 1, so that the dust-settling water in the water storage tank 71 after use can be more conveniently processed by the staff, avoiding that too much dust in the dust-settling water affects the dust-settling effect, solving the problem that the installation and dismounting of the water storage tank 71 of the original equipment are relatively troublesome. After the dust-settling water settles the mixed gas in the box body 1, the dust-settling water is collected by the water storage tank 71, meanwhile, the mixed gas is separated from the air outlet 5 by the partition plate 86, avoiding that the mixed gas in the box body 1 is directly blown out from the air outlet 5, meanwhile, the movement of the spoiler 79 increases the fusion rate of the mixed gas and the dust-settling water, so that more bubbles are generated in the dust-settling water, solving the problem that the dust-settling effect is poor due to only using spraying dust-settling.

[0025] The inside of the box 1 is provided with a knocking device for increasing the separation rate, which includes a sliding block 91, a return spring 92, a knocking rod 93, a floating ball 94, a sliding plate 95 and a push plate 96. The sliding block 91 is slidingly connected to the bottom surface of the inner wall of the water storage tank 71. When the cam 76 rotates to the sliding block 91, the sliding block 91 is pushed to slide away from the cam 76. One end of the return spring 92 is fixedly connected to the end of the sliding block 91 away from the cam 76, and the other end of the return spring 92 is fixedly connected to the inner wall of the water storage tank 71. When the sliding block 91 slides away from the cam 76, the return spring 92 is compressed. The knocking rod 93 is fixedly connected to the upper surface of the sliding block 91. When the sliding block 91 slides away from the cam 76, the knocking rod 93 is driven to impact the side wall of the water storage tank 71, causing the water storage tank 71 to vibrate, promoting the bubbles in the dust-settling water to float upwards. The sliding plate 95 is slidingly connected to the inner wall of the water storage tank 71, and the floating ball 94 is fixedly connected to the bottom surface of the sliding plate 95. The floating ball 94 always floats on the water surface due to the storage of more air inside, and as the water level rises, the floating ball 94 pushes the sliding plate 95 to slide upwards. The push plate 96 is slidingly connected to the inner wall of the water storage tank 71. When the sliding plate 95 slides to the push plate 96, the push plate 96 is pushed to slide towards the extrusion plate 710. When the sliding plate 96 slides to the extrusion plate 710, the extrusion plate 710 is pushed to slide upwards. When the dust-settling water accumulated in the water storage tank 71 is too much, the push plate 96 pushes the extrusion plate 710 to the highest position, and the extrusion plate 710 blocks the water inlet pipe 6 to stop water inflow. This knocking device promotes the mixing of gas and dust-settling water while knocking the water storage tank 71 with the sliding block 91, the return spring 92 and the knocking rod 93, promoting the bubbles generated by the spoiler 79 to float upwards, thereby improving the efficiency of air passing through the dust-settling water after dust settlement, further improving the ventilation efficiency, and solving the problem of poor ventilation efficiency of the equipment. When collecting and reusing the dust-settling water, the water level in the water storage tank 71 is monitored with the floating ball 94. When the water level is too high, the sliding plate 95 and the push plate 96 push the extrusion plate 710 to close the water inlet pipe 6, thereby avoiding the problem that when the water level in the water storage tank 71 is too high, the staff cannot handle it in time, causing the dust-settling water to overflow and damage the motor 72 and other components. This solves the problem of high water content in the box 1, which easily damages electrical appliances and causes equipment failure.

[0026] When the water storage tank 71 is filled with too much water, the limiting rod 83 is pushed towards the fixed rod 82, the limiting rod 83 drives the limiting block 85 to slide, and the limiting spring 84 is compressed. When the limiting block 85 slides away from the fixed block 81, the limiting of the water storage tank 71 is released, and the water storage tank 71 can be pulled out downwards. The dust-settled water in the water storage tank 71 and the separated dust are treated. When the water storage tank 71 needs to be reinstalled into the box body 1, the water storage tank 71 is aligned with the opening at the bottom of the box body 1 and pushed upwards. When the water storage tank 71 moves to the limiting block 85, the side of the water storage tank 71 and the inclined surface of the limiting block 85 slide with each other. The water storage tank 71 pushes the limiting block 85 to slide towards the fixed rod 82, and the limiting rod 83 is also driven to slide while the limiting spring 84 is compressed. When the water storage tank 71 is completely pushed into the box body 1, the limiting block 85 is aligned with the limiting groove in the side wall of the fixed block 81, and is no longer subjected to the pushing force. At the same time, the limiting rod 83 is subjected to the pushing force of the restoring of the limiting spring 84 and slides, driving the limiting block 85 to slide into the limiting groove and limiting the water storage tank 71. After the water tank 711 sprays water from the through hole and falls into the water storage tank 71, a certain amount of water accumulates in the water storage tank 71. When the water level in the water storage tank 71 exceeds the bottom surface of the partition plate 86, the dust-settled water cooperates with the partition plate 86 to separate the ventilation duct 3, the air inlet 4 and the air outlet 5. The air circulation from the air inlet 4 to the air outlet 5 needs to pass through the dust-settled water in the water storage tank 71. At this time, the spoiler 79 swings to promote the fusion of air and dust-settled water.

[0027] When the cam 76 rotates to the sliding block 91, the side surface of the cam 76 and the side surface of the sliding block 91 slide with each other. The cam 76 pushes the sliding block 91 to slide away from the cam 76, and the return spring 92 is compressed. When the sliding block 91 slides away from the cam 76, the knocking rod 93 hits the side wall of the water storage tank 71, causing the water storage tank 71 to vibrate and promoting the bubbles in the dust-settled water to float upwards. The floating ball 94 always floats on the water surface because it stores more air inside. As the water level rises, the floating ball 94 pushes the sliding plate 95 to slide upwards. When the sliding plate 95 slides to the push plate 96, the side of the sliding plate 95 and the inclined surface of the push plate 96 slide with each other. The sliding plate 95 pushes the push plate 96 to slide towards the extrusion plate 710. When the push plate 96 slides to the extrusion plate 710, the side of the push plate 96 and the inclined surface of the extrusion plate 710 slide with each other. The push plate 96 pushes the extrusion plate 710 to slide upwards. When the dust-settled water in the water storage tank 71 is too much, the push plate 96 pushes the extrusion plate 710 to the highest position, and the extrusion plate 710 blocks the water inlet pipe 6 to stop water inflow.

[0028] While embodiments of the application have been shown and described, it is to be understood that the embodiments described are merely exemplary of the principles and application of the present application. Numerous modifications and adaptions can be effected without departing from the spirit and scope of the present application, which is not limited to the exact construction and arrangement described. It is intended, therefore, to cover all modifications and adaptions that fall within the scope of the claims and their equivalents.
