Dust treatment device for construction work

Abstract

This utility model discloses a dust control device for construction engineering, including a trolley. A water storage tank is fixedly connected to one side of the top of the trolley, and a fixing plate is fixedly connected to the other side of the top of the trolley. A spray box is fixedly connected to one side of the fixing plate, and a spray head is movably connected to the other side of the spray box through an angle adjustment mechanism. This allows the device to spray and remove dust while moving the trolley, using the spray box and spray head to spray and remove dust. At the same time, a pressure pumping mechanism can quickly transport the spray liquid from the water storage tank to the spray box. This allows the trolley to automatically and continuously replenish water while spraying, eliminating the need for continuous water replenishment using water pumps or other equipment during spraying. This greatly reduces the power consumption of the device during dust removal and significantly improves its energy efficiency.

Technical Field

[0001] This utility model relates to the field of building engineering technology, specifically to a dust control device for building engineering. Background Technology

[0002] Dust pollution during construction is becoming increasingly serious, threatening the health of construction workers and nearby residents, severely damaging the ecological environment, and violating the concept of green construction. Currently, commonly used dust control devices in construction projects mainly include water spraying equipment, mist cannons, and baghouse dust collectors. Water spraying equipment adsorbs dust particles by spraying water mist, mist cannons use high pressure to atomize water and spray it into the air to achieve dust suppression, and baghouse dust collectors rely on filter materials to intercept dust.

[0003] Existing water spraying dust suppression equipment typically uses a water pump to continuously replenish water during the spraying dust suppression process. This existing method continuously consumes electricity, thereby increasing the cost of spraying dust suppression. In addition, existing spraying devices are not easy to adjust the spraying angle, which limits the spraying range and results in poor dust suppression effect. Utility Model Content

One side of the connecting cylinder is fixedly connected to the spray head, and the other side of the connecting cylinder is fixedly connected to a water inlet hose. The end of the water inlet hose away from the connecting cylinder is fixedly connected to the spray box.

[0008] Furthermore, the upper ends of the negative pressure box are fixedly connected to the spray box and the water storage box respectively through pipes, and one-way valves are fixedly connected to the outer surfaces of the two pipes.

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Please see Figure 1-4 This utility model provides a technical solution: a dust control device for construction engineering, including a trolley 1, a water storage tank 2 fixedly connected to one side of the top of the trolley 1, a fixing plate 3 fixedly connected to the other side of the top of the trolley 1, a spray box 4 fixedly connected to one side of the fixing plate 3, a spray head 6 movably connected to the other side of the spray box 4 through an angle adjustment mechanism, vertical plates 5 installed at the four corners of the bottom of the trolley 1, a rotating shaft 7 rotatably arranged inside the vertical plate 5, universal wheels 23 fixedly connected to the outer surface of the rotating shaft 7, and a suction mechanism provided on both sides of the fixing plate 3.

[0020] The device uses a trolley 1 as its basic carrier. A water storage tank 2 is securely connected to one side of the top of the trolley 1. The tank is made of high-strength, corrosion-resistant engineering plastic, which has good sealing properties and a large storage capacity, capable of holding enough water for spraying and meeting the needs of long-term dust control. The vertical plate 5 is made of sturdy metal, which has high strength and stability. A rotating shaft 7 is installed inside the vertical plate 5, and a high-precision bearing is installed between the rotating shaft 7 and the vertical plate 5 to reduce friction during rotation and improve the smoothness of rotation. A caster wheel 23 is fixedly connected to the outer surface of the rotating shaft 7. The caster wheel 23 is equipped with brake pads, which allows the operator to quickly fix the position of the trolley 1 when needed, ensuring the stability of the device during operation.

[0021] Furthermore, the pressure-drawing mechanism includes a negative pressure box 13 mounted on the outer surface of the fixed plate 3 and a driven shaft 15 rotatably mounted on one side of the fixed plate 3. The driven shaft 15 is connected to the rotating shaft 7 via a pulley 14. An elliptical eccentric disk 16 is fixedly connected to the outer surface of the driven shaft 15. A sealing plate 17 is slidably connected inside the negative pressure box 13. A pressing rod 18 is fixedly connected to one side of the sealing plate 17. The other end of the pressing rod 18 extends to the bottom of the negative pressure box 13 and is fixedly connected to a baffle 19. A return spring 20 is provided on the outer surface of the pressing rod 18 between the sealing plate 17 and the inner wall of the negative pressure box 13.

[0022] The driven shaft 15 is connected to the rotating shaft 7 via a pulley 14. The pulley 14 is made of high-quality rubber, which has good wear resistance and transmission efficiency. An elliptical eccentric disk 16 is fixedly connected to the outer surface of the driven shaft 15. The elliptical eccentric disk 16 can generate regular impact force during rotation. A sealing plate 17 is slidably connected inside the negative pressure box 13. The sealing plate 17 and the inner wall of the negative pressure box 13 adopt a high-precision sealing design to ensure good sealing performance. A pressing rod 18 is fixedly connected to one side of the sealing plate 17. The other end of the pressing rod 18 extends to the bottom of the negative pressure box 13 and is fixedly connected to a baffle 19. A return spring 20 is provided on the outer surface of the pressing rod 18 between the sealing plate 17 and the inner wall of the negative pressure box 13. The return spring 20 is made of high-strength spring steel, which has good elasticity and durability, and can ensure that the sealing plate 17 quickly returns to its original position after completing one insertion and withdrawal action.

[0023] Furthermore, the angle adjustment mechanism includes mounting plates 8 fixedly connected to both sides of the outer surface of the spray box 4. A motor 9 is mounted on the outer surface of one of the mounting plates 8. An adjustment shaft 10 is fixedly connected to the output end of the motor 9. The other end of the adjustment shaft 10 is rotatably connected to the other mounting plate 8. Multiple sets of connecting cylinders 11 are fixedly connected to the outer surface of the adjustment shaft 10. One side of the connecting cylinder 11 is fixedly connected to the spray head 6. A water inlet hose 12 is fixedly connected to the other side of the connecting cylinder 11. The end of the water inlet hose 12 away from the connecting cylinder 11 is fixedly connected to the spray box 4. The connecting cylinder 11 is a hollow cylinder, and the water inlet hose 12 is a telescopic hose with a certain degree of extensibility.

[0024] Among them, the motor 9 is a high-performance servo motor with stable speed and precise control. The connecting cylinder 11 is a hollow cylinder with a smooth interior, which can reduce the resistance of water flow. One side of the connecting cylinder 11 is fixedly connected to the spray head 6, and the other side is fixedly connected to the water inlet hose 12. The water inlet hose 12 is a telescopic hose with a certain degree of extensibility, which can freely extend and retract during the deflection of the spray head 6 to ensure smooth water delivery.

[0025] Furthermore, the upper ends of the negative pressure box 13 are fixedly connected to the spray box 4 and the water storage tank 2 respectively through pipes, and one-way valves 21 are fixedly connected to the outer surfaces of the two pipes.

[0026] Among them, the one-way valve 21 can ensure that the water flow can only flow in a specific direction, that is, the pipe connected to the spray box 4 can only discharge water, and the pipe connected to the water storage tank 2 can only receive water, thereby effectively preventing backflow and ensuring the stability and reliability of the water replenishment process.

[0027] Furthermore, a compression plate 22 is fixedly connected to one side of the trolley 1, and a sponge sleeve is fixedly connected to the outer surface of the compression plate 22.

[0028] The sponge sleeve is soft and provides a comfortable grip for operators, reducing fatigue from prolonged operation.

[0029] Working principle: In use, the operator first uses the casters 23 to push the trolley 1 to the work site to be dusted. Whether on muddy roads at a construction site or on uneven ground, the casters 23 can rotate flexibly and easily push the trolley 1 to the designated position. After arriving at the work site, the operator installs one-way pipes with one-way valves 21 between the water storage tank 2 and the negative pressure tank 13, and between the negative pressure tank 13 and the spray tank 4, respectively, ensuring that the pipe connections are firm and well-sealed.

[0030] After the one-way pipe is installed, the operator turns on the switch of the spray head 6. The spray head 6 is a fine atomizing nozzle, which can fully atomize the spray water inside the spray box 4 into fine water droplets. These water droplets can quickly combine with dust particles in the air, increase the weight of the dust particles, and make them settle quickly, thereby achieving efficient spray dust removal treatment of external dust.

[0031] As the trolley 1 moves, the casters 23 at the bottom rotate along with it. The rotation of the casters 23 drives the shaft 7 to rotate, and the shaft 7 transmits power to the driven shaft 15 via the pulley 14, causing the driven shaft 15 to rotate. As the driven shaft 15 rotates, the elliptical eccentric disc 16 fixed to its outer surface also rotates. The unique structural design of the elliptical eccentric disc 16 allows it to periodically impact the baffle 19 during rotation. After being impacted, the baffle 19, through the compression rod 18, drives the sealing plate 17 to repeatedly insert and withdraw inside the negative pressure chamber 13. When the sealing plate 17 is pulled outward, the space inside the negative pressure box 13 increases, the air pressure decreases, and a negative pressure is generated. Under the action of the negative pressure, the one-way pipe equipped with the one-way valve 21 quickly draws the spray water inside the water storage tank 2 into the negative pressure box 13. When the sealing plate 17 is inserted inward, the space inside the negative pressure box 13 decreases, the air pressure increases, and the water in the negative pressure box 13 is forced into the spray box 4 through another one-way pipe. This enables the trolley 1 to automatically and continuously replenish water while moving and spraying. This process does not require additional water pumps or other equipment, which greatly reduces the power consumption of the device during dust removal and significantly improves the energy efficiency of the device.

[0032] During the dust suppression spraying process, to further improve the dust removal effect, the operator can start the motor 9. The motor 9 drives the adjusting shaft 10 to continuously rotate forward and backward. The adjusting shaft 10 drives the spray head 6 to continuously deflect up and down through the connecting cylinder 11. The up and down deflection of the spray head 6 greatly expands its spraying range, thereby effectively spraying dust from high places and distant locations, thus greatly improving the dust removal effect of this device and ensuring that the air quality at the construction site is effectively improved.

[0033] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
