Description

Technical Field

[0001] This invention belongs to the field of construction engineering technology, and in particular relates to an auxiliary dust suppression device for construction engineering. Background Technology

[0002] Dust suppression plays a crucial role in construction projects. First, it effectively reduces the concentration of suspended particulate matter in the air, prevents dust dispersion, improves air quality at and around the construction site, and reduces environmental pollution. Second, effective dust suppression measures protect the health of construction workers, preventing respiratory diseases caused by long-term dust inhalation and improving operational safety. Furthermore, dust suppression helps maintain clear visibility at the construction site, reducing accidents caused by obstructed vision and improving construction efficiency and safety. It also complies with environmental regulations, avoiding penalties for dust pollution and maintaining the company's social image. Through methods such as spraying, covering, and watering, dust suppression can also inhibit the accumulation of flammable dust, reduce fire risks, and comprehensively improve the standardization of project management and the level of civilized construction.

[0003] When implementing dust suppression operations in construction areas, dust suppression devices equipped with liquid storage tanks are commonly used. The liquid inside the tank is atomized and sprayed out through a spraying method to suppress dust. However, the liquid storage tanks of existing devices are mostly open liquid storage structures without auxiliary filtration structures. As a result, impurities and sediments in the water source enter the spray pipeline directly without being intercepted, which can easily cause problems such as nozzle blockage and uneven atomization. This not only reduces the efficiency and continuity of dust suppression operations, but also affects the overall dust suppression effect. Summary of the Invention

[0015] To further understand the invention's content, features, and effects, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0016] The structure of the present invention will now be described in detail with reference to the accompanying drawings.

[0017] Please see Figures 1 to 6An auxiliary dust suppression device for construction engineering provided by this invention includes: a frame 1; a gate 2 rotatably connected to one side of the frame 1; a liquid storage device installed on the frame 1; a dust suppression assembly installed on the frame 1 for spraying dust suppression operations in the construction area; and an auxiliary filter assembly installed in the liquid storage device.

[0018] Furthermore, the liquid storage device includes: a placement frame 3 fixedly connected to the vehicle frame 1; a plurality of protective rods 4 are installed on the placement frame 3, the protective rods 4 are semi-circular, and an auxiliary wheel 5 is rotatably connected to the placement frame 3; a liquid storage cylinder 6 is installed on the placement frame 3, the top of the liquid storage cylinder 6 contacts the protective rods 4, and the bottom of the liquid storage cylinder 6 contacts the auxiliary wheel 5.

[0019] Using the above scheme: When using it for dust suppression operations in the construction area, the staff first opens the barrier 2, places one end of the liquid storage cylinder 6 on the placement frame 3, and pushes the liquid storage cylinder 6 to move on the placement frame 3. During the movement, multiple auxiliary wheels 5 help the liquid storage cylinder 6 move smoothly to the preset position. Then, liquid is injected into the liquid storage cylinder 6. After the injection is completed, the barrier 2 is closed, and the protective rod 4 is used to limit the liquid storage cylinder 6 to prevent it from moving. Then, the dust suppression component starts to work, spraying liquid to form a water mist to suppress dust in the air. At the same time, the auxiliary filter component filters impurities in the liquid. Impurities are trapped in the liquid storage cylinder 6 to ensure the purity of the liquid and prevent impurities from entering the dust suppression component and avoiding blockage.

[0020] Furthermore, the dust suppression assembly includes: a first support frame 7 fixedly connected to the vehicle frame 1; a wind duct 8 is rotatably connected inside the first support frame 7, and a plurality of atomizing nozzles 9 are installed at the output end of the wind duct 8.

[0021] Furthermore, a first motor 10 is installed on the side of the air duct 8 away from the atomizing nozzle 9, and a fan blade 11 is fixedly connected to the output end of the first motor 10.

[0022] Furthermore, a pump body 12 is installed on the top of the liquid storage tank 6; a flexible hose 13 is installed at the output end of the pump body 12, and the other end of the flexible hose 13 is connected to the air duct 8; an arc-shaped pipe 14 is installed inside the liquid storage tank 6; one end of the arc-shaped pipe 14 is connected to the input end of the pump body 12, and the other end of the arc-shaped pipe 14 is fixedly connected to a water inlet plate 15.

[0023] Using the above scheme: When in use, after the liquid storage tank 6 is installed, the pump body 12 is installed at the preset installation position on the top of the liquid storage tank 6, and one end of the flexible hose 13 is connected to the air duct 8, and the other end is connected to the output end of the pump body 12. At the same time, the input end of the pump body 12 is connected to the arc-shaped pipe 14. Then, the operator rotates the air duct 8 on the first support frame 7 to a suitable angle and starts the pump body 12. The liquid in the liquid storage tank 6 flows into the water inlet plate 15 and the arc-shaped pipe 14, and then enters the input end of the pump body 12. Subsequently, the liquid enters the flexible hose 13 from the output end of the pump body 12, and finally sprays out through the atomizing nozzle 9 in the air duct 8. At the same time, the first motor 10 drives the fan blade 11 to rotate, blowing the sprayed water mist into the air to reduce dust in the air.

[0024] Furthermore, the auxiliary filtration assembly includes: an annular groove 16 formed on the water inlet tray 15; an annular plate 17 slidably connected in the annular groove 16; a filter disc 18 fixedly connected on the annular plate 17; and a plurality of springs 19 installed between the filter disc 18 and the water inlet tray 15.

[0025] Furthermore, a first fixing frame 20 is fixedly connected inside the liquid storage tank 6; a first rotating shaft 21 is rotatably connected inside the first fixing frame 20, one end of the first rotating shaft 21 passes through the liquid storage tank 6, and a second motor 22 is installed on the liquid storage tank 6; one end of the first rotating shaft 21 is fixedly connected to the output end of the second motor 22.

[0026] Furthermore, a spiral blade 23 is fixedly connected to the first rotating shaft 21; a drive gear 24 is fixedly connected to one end of the first rotating shaft 21 near the spiral blade 23; a second fixing frame 25 is installed at the bottom of the liquid storage cylinder 6; a driven gear 26 is rotatably connected to the second fixing frame 25; the drive gear 24 meshes with the driven gear 26; a plurality of symmetrically arranged scrapers 27 are fixedly connected to one side of the driven gear 26; one side of the scraper 27 can fit against the filter disc 18.

[0027] Using the above scheme: During use, after the liquid is injected into the storage tank 6, the staff adds the dust suppressant. The second motor 22 starts, driving the first rotating shaft 21 and the spiral blade 23 to rotate. The spiral blade 23 agitates the liquid, mixing it with the dust suppressant. After the pump body 12 starts, the liquid is pushed by the spiral blade 23 to the vicinity of the water inlet plate 15, where it is filtered by the filter plate 18 to remove impurities. The continuous rotation of the first rotating shaft 21 drives the drive gear 24 to rotate, meshing with the driven gear 26, causing the driven gear 26 to rotate on the second fixed frame 25, which in turn drives the scraper 27 to rotate. The scraper 27 scrapes the filter plate. Impurities on the filter disc 18 are removed, and the rotation speed of the spiral blade 23 is adjusted to make the liquid slosh around the filter disc 18, generating an impact force that pushes the filter disc 18 to move in the annular groove 16, compressing the spring 19. During the movement of the filter disc 18, impurities are separated from the filter disc 18 under the action of the liquid, preventing them from entering the arc-shaped pipe 14 and causing blockage. When the impact force decreases, the spring force of the spring 19 causes the filter disc 18 to return to its original position and contact the scraper 27 again. The scraper 27 scrapes away the impurities, completing the liquid filtration operation. This process is repeated cyclically to ensure that impurities in the liquid are effectively removed and to prevent blockage.

[0028] The separation of impurities is explained in detail below: First, impact and oscillation separation: when the speed of the spiral blade 23 is adjusted, the liquid generates a shaking impact force around the filter plate 18, which pushes the filter plate 18 to move in the annular groove 16 to compress the spring 19. At this time, the dynamic impact force of the liquid will form an oscillating peeling force on the impurities on the surface of the filter plate 18. The sudden change in the direction and speed of the liquid flow causes the impurities adsorbed on the filter holes or surface to lose their adhesion stability, and some loose impurities will be directly shaken off by the liquid impact. Second, when the relative displacement friction separation and impact force decrease, the filter disc 18 will re-contact the rotating scraper 27 when it resets under the action of the spring 19. At the same time, the filter disc 18 itself will undergo a small-amplitude displacement in the opposite direction due to the reset of the spring 19. During this process, the scraper 27 and the surface of the filter disc 18 form relative friction. With the help of the liquid flow, the remaining stubborn impurities will be scraped by the scraper 27. At the same time, the displacement of the filter disc 18 will also destroy the interlocking state of the impurities with the filter holes, and finally they will be separated from the filter disc 18 with the liquid flow.

[0029] Working principle of the invention: When carrying out dust suppression operations in the construction area, workers first open the barrier gate 2, place one end of the liquid storage tank 6 onto the placement frame 3, and push the liquid storage tank 6 to move on the placement frame 3. During the movement, multiple auxiliary wheels 5 help the liquid storage tank 6 move smoothly to the preset position. Then, liquid is injected into the liquid storage tank 6. After the injection is completed, the workers add dust suppressant, close the barrier gate 2, and use the protective rod 4 to limit the liquid storage tank 6 to prevent it from moving. The second motor 22 starts, driving the first rotating shaft 21 and the spiral blade 23 to rotate. 3. Stir the liquid to mix it with the dust suppressant. After the liquid storage tank 6 is installed, install the pump body 12 at the preset installation position on top of the liquid storage tank 6. Connect one end of the flexible hose 13 to the air duct 8 and the other end to the output end of the pump body 12. At the same time, connect the input end of the pump body 12 to the arc-shaped pipe 14. Then, the operator rotates the air duct 8 on the first support frame 7 to a suitable angle and starts the pump body 12. The liquid in the liquid storage tank 6 flows into the water inlet pan 15 and the arc-shaped pipe 14, and then enters the input end of the pump body 12. Subsequently, the liquid flows out from the output end of the pump body 12. The liquid enters the flexible hose 13 and is finally sprayed out through the atomizing nozzle 9 in the air duct 8. At the same time, the first motor 10 drives the fan blade 11 to rotate, blowing the sprayed water mist into the air to reduce dust in the air. After the pump body 12 is started, the liquid is pushed by the spiral blade 23 to the area around the water inlet plate 15, where it is filtered for impurities by the filter plate 18. The continuous rotation of the first rotating shaft 21 drives the drive gear 24 to rotate, meshing with the driven gear 26, causing the driven gear 26 to rotate on the second fixed frame 25, which in turn drives the scraper 27 to rotate. The scraper 27 scrapes the impurities on the filter plate 18. The rotation speed of the spiral blades 23 is adjusted to make the liquid slosh around the filter disc 18, generating an impact force that pushes the filter disc 18 to move in the annular groove 16, compressing the spring 19. During the movement of the filter disc 18, under the action of the liquid, impurities are separated from the filter disc 18, preventing them from entering the arc-shaped pipe 14 and causing blockage. When the impact force decreases, the spring force of the spring 19 causes the filter disc 18 to return to its original position and contact the scraper 27 again. The scraper 27 scrapes away the impurities, completing the liquid filtration operation. This process is repeated cyclically to ensure that impurities in the liquid are effectively removed and to prevent blockage.
