Description

Technical Field

[0001] This application relates to the field of atomized dust suppression, and more specifically, to an atomized dust suppression device for construction sites. Background Technology

[0002] Dust from construction sites pollutes the environment, affects air quality, and is detrimental to environmental protection. Dust also significantly impacts the health of workers. Workers exposed to dusty environments for extended periods may have an increased risk of developing pneumoconiosis; furthermore, large amounts of dust can lead to accidents. For example, dust can obstruct vision, causing workers to lose sight and resulting in injuries. Therefore, dust control measures are necessary at construction sites.

[0003] Patent document CN116510455B discloses a dust suppression device for construction sites, mainly relating to dust suppression in construction. It includes a dust suppression box with multiple atomizing nozzles inside. A clean water tank is located on one side of the dust suppression box, and a drain pipe connects the dust suppression box and the clean water tank. A suction pipe is connected to the middle of the dust suppression box, and a negative pressure fan is installed inside the dust suppression box. Multiple suction holes are opened on the side wall of the suction pipe. An exhaust pipe is located at the top of the dust suppression box, and a water inlet pipe is located at the bottom of the clean water tank. The multiple atomizing nozzles are all connected to the water inlet pipe. The dust suppression box also has a precipitant inlet pipe and a drain pipe, with the drain pipe located below the drain pipe. A filter screen is slidably connected inside the dust suppression box. The beneficial effects are: it can effectively solve the problems of water waste and incomplete dust suppression in existing atomized dust suppression, improve the air quality at the construction site, and thoroughly clean up dust and other impurities, reducing the impact on the surrounding environment and pedestrians and vehicles at the construction site. Although the above-mentioned application documents improve the air quality at the construction site and thoroughly clean up dust and other impurities, in actual operation, as the amount of dust inhaled increases, the amount of precipitant used also increases accordingly, which directly leads to a significant increase in the cost of use.

[0034] Example 1

[0035] See Figures 1-6 This embodiment provides a dust suppression device for construction sites, including a housing 1, a water tank assembly 5 mounted on the side of the housing 1, a motor 21 mounted on the top of the housing 1, and a door 8 fixedly connected to the front of the housing 1.

[0036] A rotating tube 22 is rotatably connected to the top of the housing 1 via a bearing. A negative pressure fan 23 is mounted on the outer wall of the rotating tube 22. An extrusion block 24 is fixedly sleeved on the outer wall of the rotating tube 22. A collection trough 25 is hinged to the front of the inner wall of the housing 1. A hydraulic chamber 26 is fixedly connected to the side of the housing 1. A first hydraulic rod 27 is slidably connected to one end of the inner wall of the hydraulic chamber 26 via a piston. A spring 28 is movably sleeved on the outer wall of the first hydraulic rod 27. A second hydraulic rod 29 is slidably connected to one end of the piston inside the hydraulic chamber 26. The second hydraulic rod 29 is hinged to the side of the collection trough 25. The rotating tube 2... 2. The bottom is equipped with a rotary joint 215, and the bottom of the rotary joint 215 is fixedly connected to a diffuser 214. The diffuser 214 is fixedly connected to an atomizing tube 213. The box 1 is equipped with a dispensing device 3 for dispensing precipitant and a cleaning device 4 for cleaning impurities. Through key components such as the rotary tube 22, negative pressure fan 23, atomizing tube 213, dispensing device 3, and cleaning device 4, dust can be effectively controlled at the construction site. The dust in the air is reduced by atomization, and the cleanliness of the construction environment is increased.

[0037] A filter screen 210 is fixedly connected to the bottom of the collection tank 25, and a drain hole 211 is provided at the bottom of the inner wall of the collection tank 25. A load-bearing plate 6 is fixedly connected to the side of the box 1, and a collection box 212 is slidably connected to the load-bearing plate 6. By setting the filter screen 210 and drain hole 211 at the bottom of the collection tank 25, impurities or moisture generated during the dust suppression process can be effectively filtered and removed, preventing sediment or impurities from accumulating in the tank and ensuring the continuous normal operation of the equipment. At the same time, the design of the load-bearing plate 6 and the collection box 212 enhances the stability of the device. The outer wall of the motor 21 and the outer walls of the two rotating tubes 22 are connected by a sprocket and chain 216. A dust collection hood is fixedly connected to the top of the rotating tubes 22. The drive method of connecting the motor 21 and the rotating tubes 22 through the sprocket and chain 216 enables the power transmission of the motor 21 to the rotating tubes 22. This transmission structure enables the rotating tube 22 to drive the equipment to rotate efficiently, enhancing the atomization and dust suppression effect. Simultaneously, the top dust collection hood improves dust collection. The motor 21 drives the rotating tube 22 to rotate, which in turn drives the dust collection hood to rotate, allowing dust and air to enter the rotating tube 22 and the diffuser 214, thus achieving dust collection. The water tank assembly 5 includes a water tank 51, which is fixedly connected to the side of the housing 1. Water pumps 52 are fixedly connected to the top and bottom of the water tank 51, respectively. Connecting pipes 53 are fixedly connected to the water pumps 52. The sides of the water pumps 52 are fixedly... A drain pipe is connected, with its top fixedly connected to the bottom of the atomizing tube 213. A water pump 52 located at the bottom of the water tank 51 is fixedly connected to its bottom with a suction pipe 54. The design of the water tank assembly 5 ensures that the arrangement of the water pump 52 and connecting pipe 53 effectively provides a continuous water source for the atomizing tube 213, effectively supporting the atomization dust suppression function. The water pump 52 sprays water from the water tank through the atomizing tube 213 into the diffuser 214, mixing dust with water. The dust is then retained inside the collection tank 25 by the filter 210, achieving separation of dust from air. Dust is collected in the collection tank 25, while water is discharged through the drain hole 211. The rotating tube 22 drives the squeezing block 24 to rotate, squeezing the first hydraulic rod 27, causing it to move to the right. This increases the pressure inside the hydraulic chamber 26, driving the second hydraulic rod 29 to move upwards, causing the right side of the collection tank 25 to rise, making the left side higher than the right. Dust rolls towards the middle of the chamber 1 and finally enters the collection box 212.

[0038] In practical use, the above equipment is activated by starting the motor 21 and the negative pressure fan 23. The motor 21 drives the rotating tube 22 to rotate via the sprocket and chain 216. The rotating tube 22 drives the dust collection hood to rotate, and dust and air enter the rotating tube 22 and the diffuser 214 for discharge. Simultaneously, the water pump 52 is activated, drawing water from the water tank 51 through the connecting pipe 53 and delivering the water to the atomizing tube 213 through the drain pipe. The atomizing tube 213 sprays the discharged dust into the diffuser 214, where the water pressure drives the dust into the collection tank 25. The dust is then retained in the collection tank 25 by the filter screen 210, and the water is discharged through the drain hole 211. The rotating tube 22 rotates... When rotating, the squeezing block 24 rotates, squeezing the first hydraulic rod 27. When the first hydraulic rod 27 moves to the right, the spring 28 is compressed, increasing the internal pressure of the hydraulic chamber 26. This causes the second hydraulic rod 29 to move to the top, and the second hydraulic rod 29 causes the right side of the collection tank 25 to rise, resulting in the left side of the collection tank 25 being higher than the right side. This causes the dust inside the collection tank 25 to roll towards the middle of the box 1 and fall into the collection box 212. When the squeezing block 24 stops squeezing the first hydraulic rod 27, the spring 28 causes the first hydraulic rod 27 to move to the left. When the first hydraulic rod 27 moves to the left, the internal pressure of the hydraulic chamber 26 decreases, and the second hydraulic rod 29 descends, causing the collection tank 25 to return to a flat state.

[0039] Example 2

[0040] See Figures 1-6Based on Embodiment 1, the dispensing device 3 includes a first bevel gear 31, which is fixedly sleeved on the outer wall of the rotating tube 22. A rotating rod 38 is rotatably connected to the left side of the inner wall of the box 1 via a bearing. A second bevel gear 32 is fixedly connected to the side of the rotating rod 38. A precipitant tank 35 is fixedly connected to the side of the box 1. A peristaltic pump body 36 is fixedly connected to the side of the box 1. The output end of the peristaltic pump body 36 extends to the right side through the box 1. A rotating rod 34 is fixedly connected to the output end of the peristaltic pump body 36. The outer wall of the rotating rod 38 and the outer wall of the rotating rod 34 are connected by a first pulley 33. The dispensing device 3 uses the first bevel gear 31, the second bevel gear 32, and the peristaltic pump body 36 to precisely control the amount of precipitant dispensed. The connection between the first pulley 33 and the rotating rod 34 ensures the precise operation of the dispensing device 3, allowing the precipitant to be evenly and accurately dispensed to the designated location, thereby improving dust removal efficiency. The first bevel gear 31 and the second bevel gear 32 mesh with each other. The dispensing pipe 37 is fixedly connected to the front of the peristaltic pump body 36, extending to the right side through the housing 1. The suction pipe is fixedly connected to the front of the peristaltic pump body 36, and the other end of the suction pipe is fixedly connected to the front of the precipitant tank 35. The other end of the rotating rod 34 is rotatably connected to the right side of the inner wall of the housing 1 via a bearing. A sludge box 7 is placed at the bottom of the inner wall of the housing 1. Through the design of the peristaltic pump body 36 and the cooperation of the dispensing pipe 37, the precipitant can be effectively dispensed to the required location, preventing precipitant waste and improving work efficiency. The rotating rod 34 increases the flexibility and operability of the device, adapting to different working conditions.

[0041] In practical use, after most of the dust is collected by the collection box 212, the rotating tube 22 drives the first bevel gear 31 to rotate, the first bevel gear 31 drives the second bevel gear 32 to rotate, the second bevel gear 32 drives the rotating rod 38 to rotate, the rotating rod 38 drives the first pulley 33 to rotate, the first pulley 33 drives the rotating rod 34 to rotate, and the rotating rod 34 drives the peristaltic pump body 36 to operate. The suction pipe draws precipitant from inside the precipitant tank 35 and discharges the precipitant to the bottom of the tank 1 and inside the sludge box 7 through the dispensing pipe 37, realizing intermittent dispensing of precipitant. After the dust and water are separated, the water pump 52 at the bottom of the water tank 51 is started, and the water is drawn from the water source at the bottom of the tank 1 through the suction pipe 54 for recycling.

[0043] See Figures 1-6Based on Embodiment 1, the cleaning device 4 includes a reciprocating screw 41, which is rotatably connected to the right side of the inner wall of the housing 1 via bearings. An air purification chamber is provided on the back of the housing 1, and a baffle is fixedly connected to the front of the inner wall of the housing 1. A slot is provided on the front of the inner wall of the housing 1, and a filter plate 42 is fixedly connected to the bottom of the inner wall of the slot. A cleaning block 43 is slidably connected to the outer wall of the reciprocating screw 41. Through the design of the reciprocating screw 41 and the cleaning block 43, the cleaning device 4 can automatically clean impurities inside the housing 1, reducing the frequency of manual maintenance. The design of the filter plate 42 and the slot can filter impurities in the air, further improving air quality and ensuring stable operation of the equipment. The reciprocating screw 41 and the outer wall of the rotating rod 34 are connected by a second pulley 44. An exhaust pipe 45 is fixedly connected to the back of the air purification chamber. By connecting the reciprocating screw 41 and the rotating rod 34 through the second pulley 44, the efficiency and reliability of the cleaning device 4 are further improved. The design of the air purification chamber and exhaust pipe 45 enables the equipment to purify air, further reducing pollutants in the environment and ensuring fresh air at the construction site.

[0044] In actual use, the rotating rod 38 drives the second pulley 44 to rotate, the second pulley 44 drives the reciprocating screw 41 to rotate, and the reciprocating screw 41 drives the cleaning block 43 to scrape off impurities on the surface of the air filter plate 42. After the purified air enters the purified air chamber, it is discharged through the exhaust pipe 45.
