A linear dust reduction device and method for road construction

Abstract

The present invention relates to the technical field of dust suppression devices, specifically to a linear dust suppression device and method for road construction, comprising a base, the top surface of the base is fixedly connected to a water tank, the middle of the water tank is fixedly connected to an air duct, the middle of the air duct is provided with a debris removal component, and the top of the debris removal component is fixedly connected to an air supply chamber. An improved linear dust suppression device and method for road construction uses a spray component to perform linear spray dust suppression. When encountering strong winds, the spray component automatically changes from linear spraying to omnidirectional rotary spraying, and the spray volume increases to suppress the increased dust in the air. When the spray component changes mode, it also drives the wind force adjustment component to automatically reduce the air outlet, so that the wind speed at the air outlet is increased, so as to maintain the distance of the water mist spraying in the headwind state unchanged. During the spraying process, the debris removal component also collects dust and impurities on the ground to prevent the dust from evaporating into the air again after the water evaporates, causing secondary pollution.

Description

Technical Field

[0001] The invention relates to the technical field of dust suppression devices, and in particular to a linear dust suppression device and method for road construction. Background Art

[0002] Road engineering refers to the entire process of planning, design, construction, maintenance and management of roads as the object and the engineering entity involved. During the road construction process, a large amount of dust will be generated. Dust is an important source of dust pollution and will be blown around by the wind, causing harm and pollution to the human body and the environment. In order to reduce the dust pollution caused by road construction, dust suppression devices are needed to suppress the spread of dust, adsorb and settle dust in the air, and achieve the purpose of reducing dust pollution. Therefore, we propose a linear dust suppression device and method for road construction.

[0003] The existing patent (Announcement No.: CN118615808A) discloses a linear dust reduction device and method for highway road construction. The invention includes a mobile cart, a water storage bucket fixedly installed on the upper side of the mobile cart, a water pump connected to the water storage bucket, and a nozzle installed on the water outlet side of the water pump. Through the cooperation of a temperature sensor, a photoelectric signal transmitting module, a photoelectric signal receiving module and a humidity sensor, when the outside temperature is high and the humidity in the air is low, the control system adjusts the water pressure of the water pump to increase the water output of the water pump, and after the water mist is sprayed to the dust concentration detection area, the control system adjusts the water pressure of the water pump to reduce the water output of the water pump. When the dust concentration in the dust concentration detection area exceeds the standard again, the water output power of the water pump is increased again until the dust concentration in the dust concentration detection area meets the standard, so that the water pump uses less water output to achieve the purpose of dust reduction, effectively resolving the contradiction between the high energy consumption required for comprehensive dust reduction of the dust generated during construction and the high energy consumption required for water spraying to reduce dust. The existing technology has the following problems: the existing dust reduction device has a single spray mode and can only spray a specific area. However, when road construction is carried out outdoors, it is often accompanied by strong winds. Once the wind blows, a large amount of dust on the ground is blown up and flies with the wind. The dust reduction effect of single-direction spraying is greatly reduced. If an all-round dust reduction method is adopted, water resources will be consumed greatly. Summary of the invention

The topmost water-blocking plate among the water-blocking plates is fixedly connected with a telescopic connecting plate on one side close to the atomizing nozzle. The spray assembly is divided into two groups, and the group of spray assemblies located directly in the front is not provided with a water-blocking plate.

[0014] A road construction linear dust reduction method, using the road construction linear dust reduction device as described above, comprises the following steps: S001: A caster with a self-locking function is installed at the bottom of the base of the device, and the brake caster at the bottom is used to move it to the road construction site, and then the caster is locked, and then a group of spray assemblies without a water blocking plate are aimed at the road construction area; S002: Then the water pump and the centrifugal fan are powered on. The water pump transports the water in the water tank to the annular chamber of the transfer ring through the water pipe, and finally sprays the water out from the atomizing nozzle to atomize the water. The centrifugal fan can generate wind to blow out from the through hole in the middle of the transfer ring, blowing the atomized water a long distance to spray dust in the area within a certain distance in front. S003: When encountering strong winds, the dust on the ground is blown up, and the dust reduction effect of spraying water mist in a single direction is limited. At this time, the wind blocking scoop will rotate under the action of wind force, thereby driving the air supply chamber and the impurity removal cylinder below to rotate. When the air supply chamber rotates rapidly, under the action of centrifugal force, the sliding ring moves away from the air supply chamber, and the sliding ring drives the water blocking plate to move synchronously. The water blocking plate contacts the blockage of the atomizing nozzle, so that all spray components spray at the same time, expanding the water mist coverage area, and adaptively adjusting the spray mode according to the environment to ensure the dust reduction effect; S004: When the sliding ring in the spray assembly slides away from the air supply chamber, the guide column inside the sliding ring will slide along the internal track of the spiral groove under the extrusion of the spiral groove, thereby driving the sliding ring to move forward and rotate. The rotation of the sliding ring will drive the wind force adjustment assembly to operate through the telescopic connecting plate, and the wind speed sprayed out of the air supply chamber is adjusted by changing the size of the air outlet, ensuring that the distance of the water mist sprayed by the dust suppression device remains unchanged in the headwind state on a windy day; S005: When the centrifugal fan is working, impurities and dust on the ground will be sucked into the impurity removal component for collection, preventing the moisture in the dust from evaporating and then drifting into the air again, thus solving the dust problem from the root.

[0015] Compared with the prior art, the present invention has the following beneficial effects: In the present invention, when encountering strong winds, a large amount of dust on the ground will be blown up and dispersed into the air. At this time, the air supply chamber rotates under the action of wind, driving the water blocking plate in the spray assembly to release the blockage of the atomizing nozzle, so that all the atomizing nozzles are opened, and the linear spray in the initial state is transformed into a full-scale 360° atomizing spray, ensuring that the dust reduction device can also adaptively adjust the dust reduction mode on windy days to suppress the increased dust in the air.

[0016] In the present invention, a linear spraying dust reduction is performed in front through a front spraying assembly. During the spraying process, the centrifugal fan will suck the dust and impurities on the ground into the impurity removal assembly for collection, thereby reducing the dust that is re-dispersed into the air due to water evaporation.

[0017] In the present invention, when the water blocking plate in the spray assembly releases the blockage of the atomizing nozzle, it will also drive the wind force regulating assembly to move, reduce the diameter of the air outlet, and increase the wind speed at the air outlet, so as to maintain the distance of the water mist spraying unchanged in the headwind state, and prevent the water mist coverage area from being reduced in the headwind state.

[0022] In this embodiment, Figure 1 , Figure 2 , Figure 5 and Figure 6 to Figure 7As shown, the spray assembly 7 includes a transfer ring 701 fixedly connected to the outer ring of the air supply chamber 5, the bottom of the transfer ring 701 is connected to a water pipe 702, the middle part of the water pipe 702 runs through the middle part of the rotating ring 703, the bottom end of the water pipe 702 is fixedly connected to a sealing ring 704, the outer ring and the inner ring of the sealing ring 704 are attached with a blocking ring 705, one side of the blocking ring 705 is connected to a water pump 706, the outer ring of the transfer ring 701 is provided with a spiral groove 707, the spiral groove 707 is provided with a spiral groove 708, and the water pump 706 is connected to the outer ring of the transfer ring 701. The inner sliding plug of 07 is provided with a guide column 708, which is integrally formed in the inner ring of the sliding ring 709. The side of the sliding ring 709 away from the air supply chamber 5 is fixedly connected with a water blocking plate 7010, and the side of the water blocking plate 7010 close to the air supply chamber 5 is in contact with the water outlet of the atomizing nozzle 7011. The side of the sliding ring 709 away from the atomizing nozzle 7011 is fixedly connected with a spring telescopic rod 7012, and the end of the spring telescopic rod 7012 away from the sliding ring 709 is in contact with the water outlet of the atomizing nozzle 7011. The outer ring of the air supply chamber 5 is connected, the atomizing nozzle 7011 is fixedly installed on one side of the transfer ring 701, a through hole is opened in the middle of the transfer ring 701, and an annular cavity is opened inside the transfer ring 701, the annular cavity inside the transfer ring 701 is connected with the atomizing nozzle 7011, and the atomizing nozzle 7011 is inclined toward the central axis direction of the transfer ring 701, the rotating ring 703 is rotatably connected to the middle of the top surface of the water tank 2, and a water inlet is opened on one side of the top surface of the water tank 2, and the sealing ring 704 and two groups of blocking rings 705 form an annular closed space, the number of water blocking plates 7010 connected to the sliding ring 709 is the same as the number of atomizing nozzles 7011 on one side of the transfer ring 701 and corresponds one to one, and a water blocking plate 7010 located at the top of the water blocking plates 7010 close to the atomizing nozzle 7011 is fixedly connected with a telescopic connecting plate 7013, and the spray assembly 7 is divided into two groups, wherein the group of spray assemblies 7 located in the front is not provided with a water blocking plate 7010;When there is no wind or the wind force is relatively low, the force exerted by the wind on the choke scoop 6 is smaller than the force exerted by the spring telescopic rod 2 406 through the resistance strip 405 to squeeze the debris removal cylinder 401. At this time, the choke scoop 6 cannot drive the air supply chamber 5 and the debris removal cylinder 401 to rotate. At this time, the spring telescopic rod 1 7012, without being acted upon by the centrifugal force, has a rebound force that drives the water blocking plate 7010 to block the atomizing nozzle 7011 through the sliding ring 709, leaving only the atomizing nozzle 7011 in the front group of spray assemblies 7 in the open state. The front group of spray assemblies 7 is aimed at the target area, and the water pump 706 and the centrifugal fan 9 are started. The water pump 706 first delivers the water in the water tank 2 The water flows into the annular space formed by the sealing ring 704 and the blocking ring 705, and then enters the inner annular chamber of the transfer ring 701 through the water pipe 702, and is finally sprayed out from the atomizing nozzle 7011 to form water mist. Since the atomizing nozzle 7011 is inclined toward the central axis of the transfer ring 701, under the action of the centrifugal fan 9, when the air in the air supply chamber 5 is blown out from the through hole in the middle of the transfer ring 701, the water mist sprayed by the atomizing nozzle 7011 can be blown out, so as to spray the atomized water droplets forward to reduce dust in the target area. When encountering strong winds, in addition to the dust in the target area, the dust on the surrounding ground will be blown up by the strong wind, causing the air to The dust content in the air chamber increases significantly. At this time, the linear spray dust removal effect in a single direction is poor. Therefore, when encountering strong winds, the wind blows the wind blocking spoon 6 to drive the air supply chamber 5 to rotate, and the air supply chamber 5 rotates with the impurity removal cylinder 401 at the bottom as the axis. During the high-speed rotation of the air supply chamber 5, its outer ring will generate centrifugal force, thereby throwing the sliding ring 709 away from the air supply chamber 5. In this process, the guide column 708 on the inner side of the sliding ring 709 rotates and moves along the spiral groove 707, thereby driving the sliding ring 709 to rotate and move. The displacement of the sliding ring 709 will stretch the spring telescopic rod 7012, and at the same time, the sliding ring 709 drives the water blocking plate 70 10 gradually separates from the atomizing nozzle 7011, and under the self-rotation of the sliding ring 709, the water blocking plate 7010 also rotates with the central axis of the sliding ring 709 as the axis, so that the water blocking plate 7010 is separated from the atomizing nozzle 7011 and misaligned at the same time, ensuring that under the continuous operation of the water pump 706, the atomizing nozzles 7011 in other spray assemblies 7 except the front spray assembly 7 can also spray water mist. At this time, the dust removal device is transformed from the initial linear spraying to the full-scale spraying dust reduction in the circular range, covering a wider range and improving the dust reduction effect. The structure can automatically change the water mist spraying mode according to the weather, and the dust reduction effect is still significant even in windy days. ;

[0023] In this embodiment, Figures 2 to 4As shown, the impurity removal component 4 includes a impurity removal cylinder 401 rotatably connected to the inside of the air duct 3, a ball 402 is rollingly arranged on the bottom surface of the impurity removal cylinder 401, the top of the impurity removal cylinder 401 is connected to the inside of the air supply chamber 5, a filter screen 403 is movably connected to the top of the inner top of the impurity removal cylinder 401, and impurity removal blocks 404 are distributed in an annular manner at the bottom end of the inner part of the impurity removal cylinder 401, the outer ring of the impurity removal cylinder 401 is a wavy structure, and a resistance strip 405 is fitted on the outer ring of the impurity removal cylinder 401, and a spring telescopic rod 406 is fixedly connected to the side of the resistance strip 405 away from the impurity removal cylinder 401, and the spring telescopic rod 406 is fixedly connected to the mounting hole on the inner wall of the air duct 3, and a flow blocking column 407 is provided in the middle of the impurity removal cylinder 401, and the flow blocking column 407 is fixedly connected to the air supply chamber 5 through two connecting rods on the outer surface of the bottom end. In the middle hole of the base 1, a dust hood 408 is provided below the flow-blocking column 407, and a collecting bucket 409 is fixedly connected to the inner side of the bottom of the dust hood 408 through a connecting rod. A discharge port is provided in the middle of the collecting bucket 409, and the outer surface of the collecting bucket 409 does not contact the inner surface of the dust hood 408. The inner bottom of the collecting bucket 409 is designed in a funnel shape, and a feed port is provided in the middle of the top surface of the collecting bucket 409, and the central axis of the feed port coincides with the central axis of the air duct 3; when the centrifugal fan 9 is turned on, the air in the air supply chamber 5 is blown out from the middle through hole of the transfer ring 701, and at the same time, the external air is sucked into the air supply chamber 5 through the gap between the collecting bucket 409 and the dust hood 408 through the impurity removal cylinder 401. Since the dust hood 408 is provided on the base 1 When the air is sucked in, the impurities and dust on the ground are also sucked into the debris removal barrel 401. When the air enters the air supply chamber 5, it first passes through the gap between the dust collection hood 408 and the collection bucket 409. Since the cross-section of the gap in the vertical direction is annular and a flow-blocking column 407 is provided, part of the sucked air will first collide with each other after quickly passing through the gap area and be blocked by the flow-blocking column 407, causing the high-speed air flow rate to drop sharply. At this time, the impurities in the air fall due to the gravity being greater than the wind force and fall into the collection bucket 409 for temporary storage. Then, the air will continue to rise from the area between the flow-blocking column 407 and the debris removal barrel 401. When it just enters the interior of the debris removal barrel 401, the debris removal block 404 will come into contact with the air again, making The air is slowed down again to remove impurities, and then the air rising along the impurity removal barrel 401 is filtered by the filter 403 and enters the air supply chamber 5. The filter 403 is supported by the supporting ring on the inner wall of the impurity removal barrel 401, and a hinged semi-circular opening is provided on one side of the impurity removal barrel 401 where the filter 403 is located, which can be opened to replace the filter 403. When it is necessary to clean the impurities collected in the collecting bucket 409, open the sealing plug in the middle of the collecting bucket 409. With the design of the funnel structure at the bottom of the collecting bucket 409, the impurities will slide out of the collecting bucket 409, which is convenient for cleaning. This component can collect dust and impurities on the ground to prevent this part of the dust from floating into the air again to form dust after the water evaporates. Note that the detection device can be used while moving.

[0024] In this embodiment, Figure 1 and Figures 8 to 9 As shown, the wind force regulating assembly 8 includes a fixing ring 801 fixedly connected to one side of the intermediate ring 701, a straight notch 802 is provided in the middle of the fixing ring 801, and an arc groove 803 is provided on the side of the fixing ring 801, a toggle rod 804 is slidably penetrated in the middle of the arc groove 803, and the toggle rod 804 is integrally formed on the outer ring of the rotating disk 805, and a guide groove 806 is provided on the side of the rotating disk 805 away from the intermediate ring 701, and a square slider 807 is slidably connected inside the guide groove 806, and the square slider 807 is integrally formed on the sealing plate The side edge of the sealing plate 808 and the side of the sealing plate 808 away from the square slider 807 are integrally formed with a follower protrusion 809, and the follower protrusion 809 slides through the middle of the straight slot 802, and the toggle rod 804 is connected to the telescopic connecting plate 7013; when the blocking ring 705 rotates with the sliding ring 709, the blocking ring 705 will drive the toggle rod 804 to rotate through the telescopic connecting plate 7013, and the toggle rod 804 drives the integrally formed rotating disk 805 to rotate in the fixed ring 801, and the rotating disk 805 can squeeze through the guide groove 806 when rotating. The square slider 807 moves, and the square slider 807 drives the sealing plate 808 to move, and the sealing plate 808 slides along the straight slot 802 under the action of the follower protrusion 809. In this process, multiple sealing plates 808 can be synchronously moved toward or away from the central axis of the rotating disk 805, so as to achieve the purpose of adjusting the size of the air outlet. When the sliding ring 709 moves away from the air supply chamber 5, the sealing plate 808 moves toward the middle of the rotating disk 805 to reduce the air outlet. Since the air volume is constant, when the air outlet is reduced, the wind speed increases, and the water mist can be blown out. A longer distance, and the process of the sliding ring 709 moving away from the air supply chamber 5 is in a windy state. Therefore, when encountering strong winds, the air outlet is reduced and the water mist spraying distance is increased, so as to ensure the water mist spraying distance in the upwind direction and ensure that the water mist coverage range is not reduced. It should be noted that a group of spray assemblies 7 in the front are not provided with a water blocking plate 7010, but the telescopic connecting plate 7013 is still retained, and the telescopic connecting plate 7013 arranged on the spray assembly 7 in the front is U-shaped, which is used to connect the toggle rod 804 and the sliding ring 709.

[0025] A road construction linear dust reduction method, using the above road construction linear dust reduction device, comprises the following steps: S001: A caster with a self-locking function is installed at the bottom of the base 1 of the device, and the brake caster at the bottom is used to move the device to the road construction site, and then the caster is locked, and then a group of spray assemblies 7 without a water blocking plate 7010 is aimed at the road construction area; S002: Then, the water pump 706 and the centrifugal fan 9 are powered on, and the water pump 706 delivers the water in the water tank 2 to the annular chamber of the transfer ring 701 through the water pipe 702, and finally sprays the water out from the atomizing nozzle 7011 to atomize the water, while the centrifugal fan 9 can generate wind to blow out from the middle through hole of the transfer ring 701, blowing the atomized water a long distance to spray dust in the area within a certain distance in front; S003: When encountering strong winds, the dust on the ground is blown up, and the dust reduction effect of spraying water mist in a single direction is limited. At this time, the wind blocking scoop 6 will rotate under the action of wind force, thereby driving the air supply chamber 5 and the impurity removal cylinder 401 below to rotate. When the air supply chamber 5 rotates rapidly, under the action of centrifugal force, the sliding ring 709 moves away from the air supply chamber 5, and the sliding ring 709 drives the water blocking plate 7010 to move synchronously. The water blocking plate 7010 contacts the blockage of the atomizing nozzle 7011, so that all the spray components 7 spray at the same time, expanding the water mist coverage area, and adjusting the spray mode according to the environment to ensure the dust reduction effect; S004: When the sliding ring 709 in the spray assembly 7 slides in the direction away from the air supply chamber 5, the guide column 708 inside the sliding ring 709 will slide along the internal track of the spiral groove 707 under the pressure of the spiral groove 707, thereby driving the sliding ring 709 to move forward and rotate. The rotation of the sliding ring 709 will drive the wind force adjustment assembly 8 to operate through the telescopic connecting plate 7013, and the wind speed sprayed out of the air supply chamber 5 is adjusted by changing the size of the air outlet, so as to ensure that the distance of the water mist sprayed by the dust suppression device remains unchanged in the headwind state on a windy day; S005: When the centrifugal fan 9 is working, the impurities and dust on the ground will be sucked into the impurity removal component 4 through the impurity removal component 4 for collection, preventing the moisture in the dust from evaporating and then floating into the air again, thereby solving the dust problem from the root.

[0026] The use method and advantages of the present invention: When the road construction linear dust reduction device and method are used, the working process is as follows: First, the front spray assembly 7 is used to perform linear spraying and dust reduction in the front. During the spraying process, the centrifugal fan 9 will work to suck the dust and impurities on the ground into the impurity removal assembly 4 for collection, reducing the dust that is re-dispersed into the air due to water evaporation. When encountering strong winds, the dust on the ground will be blown up and dispersed into the air by the wind. At this time, under the action of wind, the air supply chamber 5 rotates, driving the water blocking plate 7010 in the spray assembly 7 to release the blockage of the atomizing nozzle 7011, so that all the atomizing nozzles 7011 can perform 360° atomizing spraying in all directions, ensuring that the dust reduction device also adaptively adjusts the dust reduction mode on windy days to suppress the increase of dust in the air. At the same time, when the water blocking plate 7010 in the spray assembly 7 releases the blockage of the atomizing nozzle 7011, it will also drive the wind force adjustment assembly 8 to move, reduce the diameter of the air outlet, and increase the wind speed of the air outlet, so as to maintain the distance of the water mist spraying in the headwind state unchanged, and prevent the water mist coverage area from decreasing in the headwind state.
