Description

Technical Field

[0001] This utility model relates to the field of environmental engineering technology, and in particular to an environmental engineering dust removal device. Background Technology

[0002] In the field of environmental engineering, dust pollution is one of the common environmental pollution problems, especially in construction sites, mining, material transportation and storage. The large amount of dust generated not only affects the surrounding air quality, but also poses a potential threat to the health of operators. It may also cause a series of problems such as equipment wear and tear and reduced visibility. Therefore, efficient dust removal equipment plays an important role in environmental governance.

[0003] Construction dust is caused by human activities during construction. The dust particles move with the air flow under the influence of these activities, eventually becoming fine particulate matter that is easily inhaled. Once it enters the lungs, it can cause a series of diseases and even endanger people's lives. The existing patent (publication number: CN221867872U) discloses a dust removal device for building environmental engineering. It uses a water pump to draw water from the water tank, which is then sprayed through a corrugated water pipe, a fixed water pipe, and a sprinkler pipe. Finally, the water is atomized and sprayed out through a nozzle. The water vapor adheres to the dust, thereby causing the dust to settle and purifying the air. An electric push rod allows for easy adjustment of the spray height. A motor rotates gear one, and the meshing of gear one and gear two causes the sprinkler pipe to rotate and spray, expanding the spray range and improving the practicality of the device.

[0004] To address the aforementioned problems, existing patents offer solutions. However, these dust removal devices primarily rely on spraying for dust suppression. When dust concentrations are high, a large number of dust particles rapidly combine with water mist within a short period, forming a dense and sticky mixture. Due to the significant weight of coarse dust particles, this mixture is difficult to diffuse naturally with the water flow and tends to quickly clump and accumulate on the ground. This not only requires additional manpower and resources for cleaning, increasing construction costs, but may also block construction passages and affect construction progress. Furthermore, if the accumulated mixture is not treated promptly, it is prone to re-emerge after drying, creating secondary dust and significantly reducing the dust removal effect.

[0005] Therefore, an environmental engineering dust removal device is proposed. Utility Model Content

[0006] The purpose of this invention is to provide an environmental engineering dust removal device that can solve the problem that existing dust removal equipment mainly relies on spraying for dust suppression. However, when the dust concentration is high, a large number of dust particles will quickly combine with water mist in a short period of time to form a mixture with high density and strong viscosity. Moreover, due to the large weight of coarse dust particles, this mixture is difficult to diffuse naturally with the water flow and tends to quickly clump and accumulate on the ground. This not only requires additional manpower and resources for cleaning, increasing construction costs, but may also block construction channels and affect construction progress due to the accumulation of material. At the same time, if the accumulated mixture is not dealt with in time, it is easy to be raised again after drying, forming secondary dust, which will greatly reduce the dust removal effect.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an environmental engineering dust removal device, including a movable base, a supporting plate fixedly connected to the front side of the top of the movable base, a lifting assembly provided on the front side of the supporting plate, a switching assembly provided on the front side of the lifting assembly, the switching assembly including a U-shaped frame, a rotating shaft rotatably connected inside the U-shaped frame via bearings, a rotary motor fixedly installed on the outer side of the U-shaped frame, the output shaft of the rotary motor passing through the U-shaped frame and fixedly connected to the rotating shaft, a first connecting member and a second connecting member fixedly connected to the surface of the rotating shaft, a first horizontal tube fixedly connected to the surface of the first connecting member, a second horizontal tube fixedly connected to the surface of the second connecting member, an atomizing nozzle fixedly connected to the surface of the first horizontal tube, and a dust suction hood fixedly connected to the surface of the second horizontal tube, wherein the number of atomizing nozzles and dust suction hoods are both set to multiple and evenly distributed.

[0008] Preferably, the lifting assembly includes a lifting plate, which is disposed on the front side of the supporting upright and the front side of the lifting plate is fixedly connected to the rear side of the U-shaped frame.

[0009] Preferably, lifting slots are provided on both sides of the front side of the support plate. A screw is rotatably connected inside the left lifting slot via a bearing, and a sliding rod is fixedly connected inside the right lifting slot.

[0010] Preferably, the screw has a threaded block threadedly connected to its surface, and the slide bar has a slider slidably connected to its surface. Both the threaded block and the slider are fixedly connected to the rear side of the lifting plate.

[0011] Preferably, a first corrugated hose is fixedly connected to the surface of the first horizontal pipe, a water tank is fixedly connected to the top of the movable seat, a water pump is fixedly installed on the top of the water tank and the suction end of the water pump extends into the interior of the water tank, and the side of the first corrugated pipe away from the first horizontal pipe is fixedly connected to the outlet end of the water pump.

[0012] Preferably, a vacuum pump is fixedly installed on the top of the movable seat, the suction end of the vacuum pump is fixedly connected to a dust collection box, the top of the dust collection box is fixedly connected to a second corrugated hose, and the other end of the second corrugated hose is fixedly connected to a second horizontal pipe.

[0013] Preferably, a filter screen is fixedly connected inside the dust collection box, and a sealed door is bolted to the outside of the dust collection box.

[0014] Preferably, a servo motor is fixedly installed on the top of the support plate, and the output shaft of the servo motor is fixedly connected to the top end of the screw.

[0015] Compared with the prior art, the beneficial effects of this utility model are: 1. This application sets up a switching component and uses a rotary motor to drive the rotating shaft to rotate, which can flexibly switch the working state of the first horizontal tube and the second horizontal tube. When facing high concentration of dust, the dust collection hood can be rotated to the dust area first, and the dust in the air can be collected in advance by vacuum pump and dust collection box negative pressure suction, which greatly reduces the total amount of dust during subsequent spraying. After the dust concentration is reduced, the atomizing nozzle is switched to spray dust suppression, which avoids the problem of large accumulation of mixture on the ground from the source, thereby reducing cleaning costs and the risk of secondary dust. 2. This application, by setting up a lifting component, uses a servo motor to drive the screw to rotate. With the guidance of the threaded block, slide bar, and slider, the lifting plate and switching component can move up and down, allowing the dust hood and atomizing nozzle to adapt to dust areas of different heights, thereby expanding the dust removal coverage of the equipment and further improving its flexibility of use.

[0018] 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.

[0019] Please see Figure 1-5 The present invention provides the following technical solution: An environmental engineering dust removal device includes a movable base 1. A support plate 2 is fixedly connected to the front side of the top of the movable base 1. A lifting assembly 3 is provided on the front side of the support plate 2. A switching assembly 4 is provided on the front side of the lifting assembly 3. The switching assembly 4 includes a U-shaped frame 401. A rotating shaft 402 is rotatably connected to the inside of the U-shaped frame 401 via a bearing. A rotary motor 403 is fixedly installed on the outside of the U-shaped frame 401. The output shaft of the rotary motor 403 passes through the U-shaped frame 401 and is fixedly connected to the rotating shaft 402. A first connecting member 404 and a second connecting member 405 are fixedly connected to the surface of the rotating shaft 402. A first horizontal tube 406 is fixedly connected to the surface of the first connecting member 404. A second horizontal tube 407 is fixedly connected to the surface of the second connecting member 405. An atomizing nozzle 408 is fixedly connected to the surface of the first horizontal tube 406. A dust suction hood 409 is fixedly connected to the surface of the second horizontal tube 407. The number of atomizing nozzles 408 and dust suction hoods 409 are both set to be multiple and evenly distributed.

[0020] In this embodiment: by setting the switching component 4, the U-shaped frame 401 can provide rotational support for the rotating shaft 402 and is the installation basis of the switching component 4. The rotating shaft 402 is the core rotating component. By rotating the rotating shaft 402, the first horizontal tube 406 and the second horizontal tube 407 can switch positions. The rotary motor 403 can drive the rotating shaft 402 to rotate precisely to achieve state switching. The first connector 404 and the second connector 405 are used to fix the first horizontal tube 406 and the second horizontal tube 407 respectively to ensure that the pipeline rotates synchronously with the rotating shaft 402. The first horizontal tube 406 is the execution end of spray dust suppression. The atomizing nozzle 408 can atomize water and spray it to suppress the dust remaining after dust collection. The second horizontal tube 407 is the execution end of negative pressure dust collection. Multiple dust collection hoods 409 can expand the dust collection range, thereby cooperating with the vacuum pump 9 to collect high-concentration dust.

[0021] Specifically, such as Figure 1 , Figure 4 As shown, the lifting assembly 3 includes a lifting plate 301, which is disposed on the front side of the supporting upright plate 2 and the front side of the lifting plate 301 is fixedly connected to the rear side of the U-shaped frame 401.

[0022] Specifically, such as Figure 1 , Figure 4 As shown, lifting slots 5 are provided on both sides of the front side of the support plate 2. The screw 302 is rotatably connected inside the left lifting slot 5 through a bearing, and the slide rod 303 is fixedly connected inside the right lifting slot 5.

[0023] Specifically, such as Figure 4 As shown, a threaded block 304 is threadedly connected to the surface of the screw 302, and a slider 305 is slidably connected to the surface of the slide bar 303. Both the threaded block 304 and the slider 305 are fixedly connected to the rear side of the lifting plate 301.

[0024] In this embodiment: With the above configuration, the lifting plate 301 serves as the supporting foundation. Its front side is fixedly connected to the U-shaped frame 401 of the switching component 4, while its rear side is connected to the threaded block 304 and the slider 305. It is the core component connecting the switching component 4 and the supporting upright plate 2. Through the lifting movement of the lifting plate 301, the atomizing nozzle 408 and the dust suction hood 409 can be directly driven to lift synchronously, thereby adjusting the height of the dust removal operation. The lifting groove 5 provides installation space and motion guidance for the internal screw 302, slide bar 303, threaded block 304, and slider 305, ensuring that the lifting movement follows a fixed trajectory and avoiding deviation. When the screw 302 rotates, it can... The threaded drive drives the threaded block 304 to move up and down, thereby driving the lifting plate 301 to rise and fall. The slide bar 303 can provide sliding support for the slider 305. When the lifting plate 301 moves under the drive of the screw 302, the slider 305 will slide synchronously along the slide bar 303, playing a balancing and guiding role, preventing the lifting plate 301 from tilting or jamming due to unilateral force, and ensuring the stability of the lifting process. The servo motor 14 provides power for the rotation of the screw 302. By controlling the forward and reverse rotation and speed of the servo motor 14, the rotation direction and angle of the screw 302 can be precisely controlled, thereby realizing the precise adjustment of the height of the lifting plate 301, and thus meeting the dust removal needs of different heights.

[0025] Specifically, such as Figure 2 As shown, a first corrugated hose 6 is fixedly connected to the surface of the first horizontal pipe 406, a water tank 7 is fixedly connected to the top of the movable seat 1, a water pump 8 is fixedly installed on the top of the water tank 7 and the suction end of the water pump 8 extends into the interior of the water tank 7, and the side of the first corrugated pipe away from the first horizontal pipe 406 is fixedly connected to the outlet end of the water pump 8.

[0026] Specifically, such as Figure 2 As shown, a vacuum pump 9 is fixedly installed on the top of the movable seat 1. The suction end of the vacuum pump 9 is fixedly connected to a dust collection box 10. The top of the dust collection box 10 is fixedly connected to a second corrugated hose 11, and the other end of the second corrugated hose 11 is fixedly connected to a second horizontal pipe 407.

[0027] Specifically, such as Figure 5 As shown, a filter screen 12 is fixedly connected inside the dust collection box 10, and a sealing door 13 is bolted to the outside of the dust collection box 10.

[0028] In this embodiment: With the above configuration, the first corrugated hose 6 connects the first horizontal pipe 406 to the water pump 8 outlet, serving as a water delivery channel. Its corrugated structure can flexibly deform with the lifting and rotation of the first horizontal pipe 406, ensuring unobstructed water flow without restricting the movement of the switching component 4 and the lifting component 3. The water tank 7 is a water storage container that provides water for atomized dust suppression, ensuring continuous operation of the equipment in scenarios without an external water source, thus enhancing the equipment's independence and mobility. The water pump 8 is installed on top of the water tank 7, drawing clean water from the tank through its suction end, and then pressurizing and delivering the water to the first horizontal pipe 406 via the first corrugated hose 6. This provides sufficient pressure to the atomizing nozzle 408, allowing the water to atomize into fine particles after flowing through the nozzle, enhancing the binding effect with dust. The vacuum pump 9 is the dust collection power source, generating negative pressure during operation to provide continuous suction to the dust collection hood 409, ensuring effective dust collection. The dust collection box 10 is connected to... At the suction end of the vacuum pump 9 is a dust collection container. When dust-laden air enters, the dust is trapped here, achieving gas-solid separation and preventing dust from directly entering the vacuum pump 9, causing equipment wear or secondary pollution. The second corrugated hose 11 is used to connect the second horizontal pipe 407 to the dust collection box 10, serving as a dust suction channel. Similar to the first corrugated hose 6, its deformable characteristics adapt to the lifting and rotating movements of the second horizontal pipe 407, ensuring that the dust suction path is always unobstructed. The filter screen 12 is fixed inside the dust collection box 10. When dust-laden air enters the dust collection box 10, the filter screen 12 can intercept dust particles in the air, allowing clean air to be discharged through the vacuum pump 9, improving dust collection efficiency, and protecting the vacuum pump 9 from dust corrosion. The sealing door 13 is bolted to the outside of the dust collection box 10, keeping it sealed to prevent dust leakage under normal conditions. It can be opened when cleaning is required, making it convenient for operators to regularly remove the dust collected in the dust collection box 10, ensuring the continuous and effective operation of the equipment.

[0029] Specifically, such as Figure 2 As shown, a servo motor 14 is fixedly installed on the top of the support plate 2, and the output shaft of the servo motor 14 is fixedly connected to the top of the screw 302.

[0030] In this embodiment: Through the above settings, the servo motor 14 can provide stable power for the rotation of the screw 302, and can accurately control the rotation angle of the screw 302, thereby realizing the precise adjustment of the height of the lifting plate 301 and meeting the dust removal needs of different working heights.

[0031] Working principle: First, the entire device is pushed to the dust-polluted area via the movable base 1. Then, the device position is adjusted according to the working range to ensure that the atomizing nozzles 408 or the dust hood 409 can cover the target area. If atomization dust suppression (suitable for suppressing dust diffusion) is required: the rotary motor 403 is started, and its output shaft drives the rotating shaft 402 to rotate, causing the first connecting member 404 and the first horizontal tube 406 to rotate to the working position. The second connecting member 405 and the dust hood 409 rotate with the rotating shaft 402 to the non-working state. Then, the water pump 8 is started, and the water pump 8 draws clean water from the water tank 7 and delivers it to the first horizontal tube 406 through the first corrugated hose 6. Finally, it is atomized and sprayed out through multiple atomizing nozzles 408. The water mist combines with the dust in the air and causes it to settle. If negative pressure dust collection (suitable for removing concentrated dust) is required: the rotary motor 403 is controlled to rotate in the reverse direction, causing the second connecting member 405 and the second horizontal tube 407 to rotate to the working position. The atomizing nozzles 408 and 409 rotate to the working position. 8 will rotate with the rotating shaft 402 to a non-operating state, and then the vacuum pump 9 will be started. The negative pressure generated by the vacuum pump 9 will be transmitted to the second horizontal pipe 407 through the dust collection box 10 and the second corrugated hose 11. The dust-laden air will be sucked in through multiple dust suction hoods 409. After the dust-laden air enters the dust collection box 10, the dust will be intercepted by the filter screen 12, and the clean air can be discharged through the vacuum pump 9. When a lot of dust is collected in the dust collection box 10, the sealing door 13 on the outside of the dust collection box 10 will be opened to clean the filter screen 12 and the dust collected in the dust collection box 10. Then the sealing door 13 will be closed to keep it sealed. At the same time, the servo motor 14 can be started according to the height of the dust. The servo motor 14 will drive the screw 302 to rotate. When the screw 302 rotates, the threaded block 304 will drive the lifting plate 301 to move up or down along the lifting groove 5, so that the height of the atomizing nozzle 408 or the dust suction hood 409 can be flexibly adjusted, thereby expanding the dust removal coverage area.

[0032] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
