Description

Technical Field

[0001] This invention belongs to the field of dust suppression equipment, and specifically relates to a dust suppression atomization system for construction sites. Background Technology

[0002] Dust is the primary source of air pollution at construction sites and a key area of ​​inspection for environmental protection and urban management. Current technology typically employs a perimeter sprinkler system to suppress dust around the construction site. This system consists of continuous atomizing devices installed along the top of the site's perimeter wall / fence, using high-pressure water pipes and nozzles to create an inward-sloping mist curtain to prevent dust from escaping from the site. However, this system requires a continuous supply of water for atomization, resulting in significant water consumption. Summary of the Invention

[0003] In view of the above problems, this application provides a construction site dust suppression atomization system that can reduce the amount of water used in construction site dust suppression.

[0004] This application provides a dust suppression atomization system for construction sites, including a water supply tank, a water pump, nozzles, and a collection tank. The water supply tank is used to hold water; the suction end of the water pump is located inside the water supply tank; the water pump is used to supply water to the nozzles; the collection tank is located below the nozzles, and the outlet of the collection tank is connected to the inlet of the water supply tank.

[0005] Specifically, the water pump drives the water in the tank towards the nozzles to form a continuous mist curtain, preventing dust from overflowing from the construction site. Subsequently, a portion of the mist water is collected in the collection tank under the initial pressure and gravity of the nozzles, and then circulated back into the water supply tank. This allows at least a portion of the water to be reused, reducing the water consumption in the construction site dust suppression atomization system.

[0006] In some embodiments, the construction site dust suppression atomization system further includes a sleeve and a spiral groove. The spiral groove is wound around the inner circumference of the sleeve. The inlet of the spiral groove is connected to the outlet of the collection tank, and the outlet of the spiral groove is connected to the inlet of the water supply tank. The bottom wall of the spiral groove is provided with a first protrusion. The first protrusion extends along the extension direction of the spiral groove to divide the spiral groove into a water passage area and a sedimentation area arranged radially thereon. The water passage area is closer to the axis of the spiral groove than the sedimentation area. Along the water flow direction, a second protrusion is provided at the downstream end of the first protrusion. The second protrusion connects the outer circumference of the spiral groove and one end of the first protrusion.

[0007] Specifically, as the water flows along the spiral channel toward the water supply channel, the sand and dust are more likely to move toward the outer side of the spiral channel than water due to centrifugal force, and are thus collected in the sedimentation zone. This reduces the sand and dust content in the water flowing out of the spiral channel and lowers the risk of sand and dust clogging the nozzles during recycling.

[0008] In some embodiments, the sedimentation zones are multiple zones spaced apart along the axial direction of the spiral groove; the construction site dust suppression atomization system also includes a sand discharge pipe, which is arranged parallel to the sleeve, and the sand discharge pipe is provided with sand discharge holes, which are connected to the sedimentation zones one by one.

[0009] In the above technical solution, multiple sedimentation zones are set up to filter the water flow in stages and segments, while sand discharge pipes are set up to facilitate the collection of water flow with high sand and dust content.

[0010] In some embodiments, the construction site dust suppression atomization system further includes a housing and a filter screen. The housing is disposed within a water supply tank, and the interior of the housing is connected to the outlet of the sand discharge pipe. An opening is provided at the top of the housing; the filter screen covers the opening.

[0011] In the above technical solution, by setting up a filter screen, the water in the water flow with high sand and dust content can be separated through the filter screen, thereby allowing the sand and dust to be collected inside the shell. The structure is simple and easy to implement.

[0012] In some embodiments, a water inlet is provided on one side of the housing, and a sand discharge outlet is provided at the bottom of the housing; the construction site dust suppression atomization system also includes a valve and a flushing device. The valve is located in the water supply tank and is used to open and close the sand discharge outlet; the water outlet of the flushing device is connected to the water inlet of the housing.

[0013] In the above technical solution, a flushing device is set up so that after the shell is filled with mud and sand, the valve is opened and the water flow discharged by the flushing device drives the mud and sand out of the valve.

[0014] In some embodiments, the construction site dust suppression atomization system further includes a water storage tank and a first float. The bottom of the water storage tank is connected to the bottom end of the sand discharge pipe; the first float is disposed inside the water storage tank and is connected to the switch of the flushing device.

[0015] Specifically, when sand and dust block the filter screen, preventing water from entering the shell through the sand discharge pipe, water accumulates inside the sand discharge pipe. Due to the principle of communicating vessels, the water level in the storage tank rises, causing the first float to rise and triggering the flushing device to clean the sand and dust inside the shell.

[0016] In some embodiments, the construction site dust suppression atomization system further includes a transmission rod and a first connecting rope. The middle portion of the transmission rod is rotatably disposed above the water supply tank. The transmission rod includes a first end and a second end disposed opposite to each other, and a first float is tractively connected to the first end. The first connecting rope connects the second end to the switch of the flusher. The transmission rod has a first position and a second position. In the first position, the first end is located above the second end. When switching from the first position to the second position, the second end rotates toward the water supply tank to drive the switch of the flusher to switch to the open position. The liquid level in the water tank rises, causing the first float to drive the transmission rod to move from the first position to the second position.

[0017] In the above technical solution, the first float and the flushing device are connected by a transmission rod and a first connecting rope, which is simple in structure and easy to implement.

[0018] In some embodiments, the construction site dust suppression atomization system further includes a second float and a second connecting rope. The second float is located in a water supply tank; the second connecting rope connects the second float to a second end; the liquid level in the water supply tank drops, causing the second float to drive the transmission rod to move from a first position to a second position.

[0019] Specifically, when the water level in the supply tank drops to a certain threshold, the second connecting rope tightens, and the second float applies tension to its second end via the second connecting rope, causing the second end to press downwards. Simultaneously, this causes the first end to move the first float upwards. This moves the transmission rod from the first position to the second position, triggering the flushing switch. The flushing then discharges water into the housing, allowing the water to pass through the filter screen and enter the supply tank, causing the water level in the supply tank to rise and lift the second float. This, in turn, moves the transmission rod back to the first position until the second connecting rope is slack.

[0020] In some embodiments, the construction site dust suppression atomization system further includes a first connecting rod, a second connecting rod, and a third connecting rope. One end of the first connecting rod is connected to a first float; one end of the second connecting rod is movably connected to the first end; the third connecting rope connects the other end of the first connecting rod away from the first float and the other end of the second connecting rod away from the first end; a guide hole is provided in the water tank, and both the first connecting rod and the second connecting rod are disposed in the guide hole.

[0021] Specifically, when sand and dust clog the filter screen, preventing water from entering the housing through the sand discharge pipe, water accumulates inside the pipe. Due to the principle of communicating vessels, the water level in the storage tank rises, causing the first float to rise. This raises the first connecting rod, which then abuts against the second connecting rod, driving the first end upwards. At this point, the first connecting rope is slack and does not restrict the second end from pressing down. This causes the transmission rod to move from the first position to the second position, triggering the flushing switch. The flushing then discharges water into the housing. If the valve is open, the water flow will carry sand and dust out, relieving the blockage and allowing water from the sand discharge pipe to enter the housing. This causes the liquid level in the sand discharge pipe to drop, which in turn lowers the liquid level in the storage tank, causing the first float to fall. This, in turn, moves the transmission rod to the first position, closing the flushing switch.

[0022] In some embodiments, the guide hole has a first hole wall and a second hole wall disposed opposite to each other, the second hole wall being closer to the water supply tank than the first hole wall, and a first guide surface being disposed at the other end of the first connecting rod away from the first float; in the first position, there is a gap between the first connecting rod and the second connecting rod and the first hole wall, and the distance between the first guide surface and the second hole wall gradually increases along the direction from the first connecting rod to the second connecting rod; the valve is an electric valve, and the valve switch of the electric valve is disposed on the first hole wall.

[0023] Specifically, when the water level in the water tank drops to a certain threshold, the second connecting rope tightens, and the second float applies tension to its second end through the second connecting rope, causing the second end to press downwards. Simultaneously, this causes the first end to move the first float upwards. This moves the transmission rod from the first position to the second position. During this period, the second connecting rod, through the third connecting rope, drives the first connecting rod and the first float upwards. At this time, there is a gap between the first connecting rod and the wall of the first hole, preventing the electric valve from opening or closing. This keeps the electric valve closed, allowing the flusher to discharge water into the housing, which then passes through the filter screen and enters the water tank. When sand and dust clog the filter screen, preventing water from entering the housing through the sand discharge pipe, water accumulates inside. Due to the principle of communicating vessels, the water level in the storage tank rises, causing the first float to rise. This causes the first connecting rod to rise and abut against the second connecting rod. Under the action of the first guide surface, the first connecting rod moves towards the first hole wall until it abuts against it. Then, limited by the guide hole, the first connecting rod drives the second connecting rod upwards, triggering the electric valve to open. At this point, the first connecting rope is slack and does not restrict the downward pressure of the second end. This causes the transmission rod to move from the first position to the second position, triggering the flushing device. The flushing device then discharges water into the housing, and the water flow carries sand and dust out through the valve. Attached Figure Description

[0031] Reference Figures 1-10 This application provides a construction site dust suppression atomization system 100, including a water supply tank 10, a water pump 20, a nozzle 21, and a collection tank 30. The water supply tank 10 is used to hold water; the suction end of the water pump 20 is located inside the water supply tank 10; the water pump 20 is used to supply water to the nozzle 21; the collection tank 30 is located below the nozzle 21, and the outlet of the collection tank 30 is connected to the inlet of the water supply tank 10.

[0032] In some embodiments, the construction site dust suppression atomization system 100 further includes a connecting water pipe, which is connected to the water pump 20 and extends horizontally and is located above the fence. The nozzles 21 may be multiple nozzles spaced apart along the water pipe.

[0033] Specifically, the water pump 20 drives the water in the tank towards the nozzle 21 to form a continuous mist curtain, preventing dust from overflowing from the construction site. Subsequently, part of the mist water is collected by the collection tank 30 under the initial pressure and gravity of the nozzle 21, and then circulated back into the water supply tank 10. This allows at least a portion of the water to be recycled, reducing the amount of water used in the construction site dust suppression atomization system 100.

[0034] According to some embodiments of this application, please refer to Figure 4 , Figure 7 and Figure 8The construction site dust suppression atomization system 100 also includes a sleeve 31 and a spiral groove 32. The spiral groove 32 is wound around the inner circumference of the sleeve 31. The water inlet of the spiral groove 32 is connected to the water outlet of the collection tank 30, and the water outlet of the spiral groove 32 is connected to the water inlet of the water supply tank 10. The bottom wall of the spiral groove 32 is provided with a first protrusion 321. The first protrusion 321 extends along the extension direction of the spiral groove 32 to divide the spiral groove 32 into a water passage area 32B and a sedimentation area 32A arranged radially. The water passage area 32B is closer to the axis of the spiral groove 32 than the sedimentation area 32A. Along the water flow direction, a second protrusion 322 is provided at the downstream end of the first protrusion 321. The second protrusion 322 connects the outer circumference of the spiral groove 32 and one end of the first protrusion 321.

[0035] In some embodiments, the maximum depth of the sedimentation zone 32A is greater than the maximum depth of the water passage zone 32B, so as to facilitate the accumulation of sand and dust in the sedimentation zone 32A.

[0036] Specifically, as the water flows along the spiral groove 32 toward the water supply tank 10, the sand and dust will move more easily toward the outside of the spiral groove 32 than the water due to the centrifugal force, and will be collected in the sedimentation zone 32A, thereby reducing the sand and dust content in the water flowing out of the spiral groove 32 and reducing the risk of sand and dust clogging the nozzle 21 during the recycling process.

[0037] According to some embodiments of this application, please refer to Figure 3 and Figure 4 Please refer to Figure 7 and Figure 8 The sedimentation zone 32A consists of multiple zones spaced apart along the axis of the spiral groove 32; the construction site dust suppression atomization system 100 also includes a sand discharge pipe 40, which is arranged parallel to the sleeve 31. The sand discharge pipe 40 is provided with sand discharge holes 40A, which are connected to the sedimentation zone 32A one by one.

[0038] Understandably, the first protrusion 321 and the second protrusion 322 are a plurality of portions spaced apart along the axial direction of the spiral groove 32 to form a plurality of sedimentation zones 32A spaced apart along the axial direction of the spiral groove 32. In some embodiments, each first protrusion 321 may extend 1.5 turns along the extending direction of the spiral groove 32, and 0.5 turns of the spiral groove 32 may be provided between two adjacent first protrusions 321.

[0039] In the above technical solution, multiple sedimentation zones 32A are set up to filter the water flow in stages and segments, while the sand discharge pipe 40 is set up to facilitate the collection of water flow with high sand and dust content.

[0040] According to some embodiments of this application, please refer to Figure 1 , Figure 3 and Figure 5The construction site dust suppression atomization system 100 also includes a housing 41 and a filter screen 42. The housing 41 is located inside the water supply tank 10, and the interior of the housing 41 is connected to the outlet of the sand discharge pipe 40. An opening is provided on the top of the housing 41; the filter screen 42 covers the opening.

[0041] For example, the filter screen can be a woven fabric filter screen, a ceramic filter plate, etc.

[0042] In the above technical solution, by setting up a filter screen 42, the water in the water flow with high sand and dust content can be separated by the filter screen 42, thereby allowing the sand and dust to be collected in the shell 41. The structure is simple and easy to implement.

[0043] According to some embodiments of this application, please refer to Figure 5 and Figure 7 The housing 41 has a water inlet on one side and a sand discharge outlet at the bottom. The construction site dust suppression atomization system 100 also includes a valve 43 and a flushing device 44. The valve 43 is located in the water supply tank 10 and is used to open and close the sand discharge outlet. The outlet of the flushing device 44 is connected to the water inlet of the housing 41.

[0044] It should be noted that the flushing device 44 can be a pull-cord type flushing device 44, which is existing technology and will not be described in detail here.

[0045] In the above technical solution, a flushing device 44 is set so that after the shell 41 is filled with mud and sand, the valve 43 is opened and the water flow discharged by the flushing device 44 drives the mud and sand out of the valve 43.

[0046] According to some embodiments of this application, the construction site dust suppression atomization system 100 further includes a water storage tank 45 and a first float 46. The bottom of the water storage tank 45 is connected to the bottom end of the sand discharge pipe 40; the first float 46 is disposed in the water storage tank 45 and is connected to the switch of the flushing device 44.

[0047] Specifically, when sand and dust block the filter screen 42, preventing water from entering the shell 41 through the sand discharge pipe 40, water will accumulate in the sand discharge pipe 40. As a result, due to the principle of communicating vessels, the water level in the water storage tank 45 will rise, which will cause the first float ball 46 to rise, thereby triggering the flusher 44 to clean the sand and dust in the shell 41.

[0048] According to some embodiments of this application, please refer to Figure 6 , Figure 9 and Figure 10The construction site dust suppression atomization system 100 also includes a transmission rod 50 and a first connecting rope 51. The middle part of the transmission rod 50 is rotatably disposed above the water supply tank 10. The transmission rod 50 includes a first end and a second end disposed opposite to each other. A first float ball 46 is drivenly connected to the first end. The first connecting rope 51 connects the second end to the switch of the flusher 44. The transmission rod 50 has a first position and a second position. In the first position, the first end is located above the second end. When switching from the first position to the second position, the second end rotates towards the water supply tank 10 to drive the switch of the flusher 44 to switch to the open position. The liquid level in the water tank 45 rises, so that the first float ball 46 drives the transmission rod 50 to move from the first position to the second position.

[0049] In the above technical solution, the first float 46 and the flusher 44 are connected by a transmission rod 50 and a first connecting rope 51, which is simple in structure and easy to implement.

[0050] According to some embodiments of this application, the construction site dust suppression atomization system 100 further includes a second float 60 and a second connecting rope 61. The second float 60 is located inside the water supply tank 10; the second connecting rope 61 connects the second float 60 to the second end; the liquid level in the water supply tank 10 drops, so that the second float 60 drives the transmission rod 50 to move from a first position to a second position.

[0051] Understandably, the density of the second float 60 can be equal to that of the first float 46, and the volume of the second float 60 can be much larger than that of the first float 46, so that when the liquid level in the water supply tank 10 drops to a certain threshold, the second float 60 can drive the second end to press down.

[0052] Specifically, when the liquid level in the water supply tank 10 drops to a certain threshold, the second connecting rope 61 tightens, and the second float 60 applies tension to its second end through the second connecting rope 61, causing the second end to press downwards. Simultaneously, this causes the first end to move the first float 46 upwards. This causes the transmission rod 50 to move from the first position to the second position, triggering the switch of the flushing device 44. This causes the flushing device 44 to discharge water into the housing 41, and the water passes through the filter screen 42 into the water supply tank 10, causing the liquid level in the water supply tank 10 to rise and lift the second float 60. This, in turn, causes the transmission rod 50 to move back to the first position until the second connecting rope 61 is relaxed.

[0053] According to some embodiments of this application, please refer to Figure 6 , Figure 9 and Figure 10The construction site dust suppression atomization system 100 also includes a first connecting rod 461, a second connecting rod 462, and a third connecting rope 463. One end of the first connecting rod 461 is connected to the first float 46; one end of the second connecting rod 462 is movably connected to the first end; the third connecting rope 463 connects the other end of the first connecting rod 461 away from the first float 46 and the other end of the second connecting rod 462 away from the first end; a guide hole 451 is provided in the water tank 45, and both the first connecting rod 461 and the second connecting rod 462 are located in the guide hole 451.

[0054] Specifically, when sand and dust clog the filter screen 42, preventing water from entering the housing 41 through the sand discharge pipe 40, water accumulates in the sand discharge pipe 40. This causes the water level in the storage tank 45 to rise due to the principle of communicating vessels, leading to the rise of the first float 46. This causes the first connecting rod 461 to rise and abut against the second connecting rod 462, thus driving the first end upwards. At this time, the first connecting rope 51 is slack and does not restrict the downward pressure of the second end. This causes the transmission rod 50 to move from the first position to the second position, triggering the switch of the flusher 44. This allows the flusher 44 to discharge water into the housing 41. If the valve 43 is open at this time, the water flow will carry sand and dust out from the valve 43, thereby relieving the blockage in the housing 41. This allows the water in the sand discharge pipe 40 to enter the housing 41, causing the liquid level in the sand discharge pipe 40 to drop, which in turn causes the liquid level in the water tank 45 to drop, causing the first float 46 to drop. This, in turn, drives the transmission rod 50 to move to the first position, so that the flusher 44 is in the closed state.

[0055] According to some embodiments of this application, please refer to Figure 6 , Figure 9 and Figure 10 The guide hole 451 has a first hole wall 451A and a second hole wall 451B that are arranged opposite to each other. The second hole wall 451B is closer to the water supply tank 10 than the first hole wall 451A. The other end of the first connecting rod 461 away from the first float 46 is provided with a first guide surface 4611. In the first position, there is a gap between the first connecting rod 461 and the second connecting rod 462 and the first hole wall 451A. Along the direction from the first connecting rod 461 to the second connecting rod 462, the distance between the first guide surface 4611 and the second hole wall 451B gradually increases. The valve 43 is an electric valve, and the valve switch 431 of the electric valve is provided on the first hole wall 451A.

[0056] In some embodiments, the other end of the second connecting rod 462 away from the transmission rod 50 is provided with a second guide surface 4621. In the first position, the distance between the second guide surface 4621 and the second hole wall 451B gradually increases along the direction from the first connecting rod 461 to the second connecting rod 462.

[0057] Specifically, when the liquid level in the water supply tank 10 drops to a certain threshold, the second connecting rope 61 tightens, and the second float 60 applies tension to its second end through the second connecting rope 61, causing the second end to press downwards. At the same time, the first end drives the first float 46 to move upwards. This causes the transmission rod 50 to move from the first position to the second position. During this period, the second connecting rod 462 drives the first connecting rod 461 and the first float 46 to move upwards through the third connecting rope 463. At this time, there is a gap between the first connecting rod 461 and the first hole wall 451A, which will not trigger the valve switch 431 of the electric valve, so the electric valve is in the closed state. This allows the flusher 44 to discharge water into the housing 41, which will pass through the filter screen 42 and enter the water supply tank 10. When sand and dust clog the filter screen 42, preventing water from entering the housing 41 through the sand discharge pipe 40, water accumulates in the sand discharge pipe 40. Due to the principle of communicating vessels, the water level in the storage tank 45 rises, causing the first float 46 to rise. This causes the first connecting rod 461 to rise and abut against the second connecting rod 462. Under the action of the first guide surface 4611, the first connecting rod 461 moves towards the first hole wall 451A until it abuts against the first hole wall 451A. Then, limited by the guide hole 451, the first connecting rod 461 drives the second connecting rod 462 upwards, triggering the valve switch 431 of the electric valve, opening it. At this time, the first connecting rope 51 is slack and does not restrict the downward pressure of the second end. This causes the transmission rod 50 to move from the first position to the second position, triggering the switch of the flusher 44. This allows the flusher 44 to discharge water into the housing 41, and the water flow will carry sand and dust out from the valve 43.

[0058] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0059] The above embodiments are only used to illustrate the technical solutions of this application and are not intended to limit this application. For those skilled in the art, this application can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
