Description

Technical Field

[0001] The invention relates to the field of construction dust reduction structures, and in particular to an environmentally friendly dust reduction device for engineering construction. Background Art

[0002] Environmental protection dust reduction technology for construction projects refers to various technical measures taken to reduce dust during the construction of construction projects in order to reduce air pollution and protect the environment. These technologies may include spraying water to reduce dust, using dust-proof nets, sealing construction sites, using low-dust materials and equipment, etc. Through these measures, dust emissions during the construction process can be effectively controlled to reduce the impact on the surrounding environment and personnel health.

[0003] Highway engineering includes surveying, measuring, design, construction, maintenance and management. The dust generated during the construction process will pollute the air and threaten the health of workers and pedestrians. In order to reduce the impact of dust on people and the environment, atomizing dust suppressors are usually used for treatment. At present, in the process of road construction, the most common method is to install a spray head on the top of the shielding wall, and use high-pressure gas to make the water flow form a spray effect. The formation of the above spray requires a more complex structure for the compressed air path and the water flow air path, which makes the application process more complicated. In particular, local spraying cannot be achieved, and the spray effect of the entire layout section is turned on and off at the same time. Summary of the invention

[0030] Reference Figures 1 to 7 In one embodiment of the present invention, an environmentally friendly dust reduction device for engineering construction includes a plurality of dust reduction units 010 that are detachably connected to each other, and the dust reduction unit 010 includes:

[0031] The water tank 100 has a water storage cavity inside, and two opposite ends of the water tank 100 in the width direction are provided with a water tank inlet pipe 110 and a water tank outlet pipe 120 both connected to the water storage cavity and shaped to form a butt fit, and the water tank inlet pipe 110 and the water tank outlet pipe 120 are provided at the upper part of the water tank 100 in the height direction;

[0032] The atomizer box assembly 200 is arranged at the upper end of the water tank 100 and includes an atomizer box 210 and a drive circuit 220. The bottom of the atomizer box 210 is a water reservoir 211. The two ends of the atomizer box 210 in the width direction are oppositely provided with an atomizer inlet pipe 212 and an atomizer outlet pipe 213, both of which are connected to the water reservoir 211 and are shaped to form a docking fit. The drive circuit 220 is arranged from the atomizer inlet pipe 212 to the atomizer outlet pipe 213. The bottom of the water reservoir 211 is provided with a plurality of atomizer sheets 220 electrically connected to the drive circuit 220 and arranged at intervals in the length direction of the water reservoir 211. The position of the atomizer box 210 corresponding to the atomizer sheet 220 is vacant, wherein, when the atomizer inlet pipe 212 and the atomizer outlet pipe 213 are docked, the two drive circuits 220 are electrically connected;

[0033] A water return pipe 200 is connected between the water tank outlet pipe 120 and the atomization inlet pipe 212 on the outermost dust reduction unit 010 .

[0034] In the prior art, the formation of the spray requires a compressed air path and a water flow air path, which requires a relatively complex structure, making the application process relatively complicated; in particular, local spraying cannot be achieved, and the spray effect of the entire layout section is turned on and off at the same time.

[0035] The environmentally friendly dust reduction device for engineering construction of the present invention comprises a plurality of dust reduction units 010 that are detachably connected to each other, and the arrangement in the construction area is achieved by combining the dust reduction units 010. The dust reduction unit 010 comprises a water tank 100 and an atomization box assembly 200.

[0036] The interior of the water tank 100 is a water storage chamber. A water tank inlet pipe 110 and a water tank outlet pipe 120 are arranged at both ends of the water tank 100 in the width direction, both of which are connected to the water storage chamber and are shaped to form a docking fit. The connection method between the water tank inlet pipe 110 and the water tank outlet pipe 120 of two adjacent dust reduction units 010 can be various, and is not limited to direct connection (for example, the connection can also be achieved through a connecting structure). The connection between the water tank inlet pipe 110 and the water tank outlet pipe 120 should ensure a sealing effect (which can be achieved by adding a sealing ring, etc.). The water tank inlet pipe 110 and the water tank outlet pipe 120 are arranged at the upper part of the water tank 100 in the height direction, so that the water flow can be smoothly driven to flow between the water tanks 100, and the sedimentation process can be naturally completed in the water tank 100.

[0037] The atomizer box assembly 200 is arranged at the upper end of the water tank 100 and includes an atomizer box 210 and a drive circuit 220. The bottom of the atomizer box 210 is a water tank 211. The two ends of the atomizer box 210 in the width direction are relatively provided with an atomizer outlet pipe 213 and an atomizer inlet pipe 212, both of which are connected to the water tank 211 and are shaped to form a docking fit. The connection method between the atomizer inlet pipe 212 and the atomizer outlet pipe 213 of two adjacent dust reduction units 010 can be various, and is not limited to direct connection (such as connection can also be achieved through a connecting structure). The drive circuit 220 is arranged from the atomizer inlet pipe 212 to the atomizer outlet pipe 213. A plurality of atomizer sheets 220 electrically connected to the drive circuit 220 and arranged at intervals in the length direction of the water tank 211 are arranged at the bottom of the water tank 211. The position of the atomizer box 210 corresponding to the atomizer sheet 220 is vacant, so as not to block the operation of the atomizer sheet 220 (for example, a window structure 214 is provided at the position corresponding to the atomizer sheet 220 on the atomizer box 210). When the atomizer inlet pipe 212 and the atomizer outlet pipe 213 are docked, the two drive circuits 220 form an electrical connection. The drive circuit 220 of the first dust reduction unit 010 is connected to an external power source.

[0038] The two ends of the return pipe 200 in the height direction are respectively detachably fixed to the water tank outlet pipe 120 and the atomization inlet pipe 212. The return pipe 200 can guide the water flow from the last dust reduction unit 010 back to the first dust reduction unit 010.

[0039] During the process of connecting multiple dust reduction units 010 in series, the atomizer box assembly 200 is also connected in series. The atomizer inlet pipe 212 and the atomizer outlet pipe 213 on the adjacent atomizer box assembly 200 are fixed to each other. When multiple dust reduction units 010 are connected in series, the water tank 100 of the first dust reduction unit 010 is the water inlet end and the water outlet end, and the return pipe 200 is connected to the water tank outlet pipe 120 and the atomizer inlet pipe 212 of the last dust reduction unit 010. During operation, water is pumped into the water tank inlet pipe 110 of the first water tank 100, and after the water flows through each water tank 100 in sequence, it flows out from the water tank outlet pipe 120 of the last water tank 100 and enters the return pipe 200, and then after passing through the last atomizer box 210, the water flows through each atomizer box 210 in sequence and returns to the atomizer box 210 of the first dust reduction unit 010.

[0040] In summary, multiple dust reduction units 010 are connected, and water tank inlet pipes 110 and water tank outlet pipes 120 are arranged at the upper parts of both ends of the water tank 100 in the width direction, so that the water flow can be smoothly driven to flow between the water tanks 100, and the sedimentation process can be naturally completed in the water tank 100, thereby ensuring the operation of the atomizer sheet 220; atomizer outlet pipes 213 and atomizer inlet pipes 212 are arranged at both ends of the atomizer box 210 in the width direction, and when the atomizer inlet pipes 212 and the atomizer outlet pipes 213 are docked, the driving circuits 220 on the two atomizer box assemblies 200 are electrically connected. A plurality of atomizing sheets 220 electrically connected to the driving circuit 220 are provided at the bottom of the water storage tank 211; the two ends of the return water pipe 200 in the height direction are respectively detachably fixed to the water tank outlet pipe 120 and the atomizing inlet pipe 212, and the water flow can be guided from the last dust reduction unit 010 back to the first dust reduction unit 010 through the return water pipe 200; the environmentally friendly dust reduction device for engineering construction has a simple structure, and the water flow operation can be completed on one side; the atomizing sheet 220 on each dust reduction unit 010 can be independently started or shut down.

[0041] Reference Figure 6 In one embodiment, the environmentally friendly dust reduction device for engineering construction also includes a circulating water pump 300 and a water tank 400 that are arranged in conjunction with each other. The circulating water pump 300 is connected to the water tank inlet pipe 110 of the first dust reduction unit 010, and the atomization outlet pipe 213 of the first dust reduction unit 010 is connected to the water tank 400.

[0042] In this embodiment, the circulating water pump 300 works continuously to drive the water flow from the first water tank 100 to the last water tank 100, and then from the last atomizer box 210 to the first atomizer box 210, and finally returns to the water tank 400 from the atomizer outlet pipe 213 of the first atomizer box 210. During this process, the water level of the atomizer box 210 remains unchanged (specifically, the bottom height of the atomizer outlet pipe 213), thereby eliminating the need for water flow control and not wasting water resources. At the same time, each water tank 100 acts as a sedimentation tank, and the relevant particulate impurities can be settled in the water tank 100, so that the content of particulate impurities in the water flow entering the atomizer box 210 is controlled, ensuring the normal operation of the atomizer sheet 220.

[0043] In one embodiment, the water return pipe 200, the atomization inlet pipe 212 and the atomization outlet pipe 213 are all hard pipes.

[0044] In this embodiment, when multiple dust reduction units 010 are connected in series, the atomizer box assembly 200 is also connected in series. The atomizer inlet pipe 212 and the atomizer outlet pipe 213 on the adjacent atomizer box assembly 200 are fixed to each other. When multiple dust reduction units 010 are connected in series, the water tank 100 of the first dust reduction unit 010 is the water inlet end and the water outlet end, and the return pipe 200 is connected to the water tank outlet pipe 120 and the atomizer inlet pipe 212 of the last dust reduction unit 010. During operation, water is pumped into the water tank inlet pipe 110 of the first water tank 100, and the water flows through each water tank 100 in sequence, and then flows out from the water tank outlet pipe 120 of the last water tank 100, and enters the return pipe 200, and then after passing through the last atomizer box 210, the water flows through each atomizer box 210 in sequence and returns to the atomizer box 210 of the first dust reduction unit 010. The first atomizer box assembly 200 can be fixed in various ways, which are not specifically limited. The last atomizer box assembly 200 is supported by the return pipe 200. The atomizer inlet pipe 212 and the atomizer outlet pipe 213 are also hard pipes, so adjacent atomizer box assemblies 200 can be fixed to each other.

[0045] In one embodiment, the atomizer sheet 220 has a tendency to tilt 5 to 10 degrees toward the outside of the atomizer box 210 in the thickness direction.

[0046] In this embodiment, the atomizing sheet 220 is arranged to be inclined so that the angle of the water mist is directed toward the construction location, so that the dust reduction effect is better. At the same time, the atomizing sheet 220 is arranged to be inclined so that the possibility of impurities accumulating on its surface is reduced.

[0047] In one embodiment, the plurality of atomizing sheets 220 are arranged at intervals in the thickness direction of the atomizing box 210 , and are respectively inclined toward two outer sides in the thickness direction of the atomizing box 210 .

[0048] In this embodiment, the multiple atomizing sheets 220 are divided into two batches, one batch works toward the outside of the atomizing box 210 in the thickness direction, and the other batch works toward the inside of the atomizing box 210 in the thickness direction. The multiple atomizing sheets 220 form two groups of water mist facing inward and outward respectively, forming a double dust reduction effect.

[0049] Reference Figures 1 to 5 In one embodiment, a switch 230 is connected between the plurality of atomizing sheets 220 and the driving circuit 220 , and the switch 230 is disposed on the water tank 100 or the atomizing box 210 .

[0050] In this embodiment, by adding a switch 230, the atomizing sheet 220 on each dust reduction unit 010 can be independently started and closed, so that when multiple environmental dust reduction devices for engineering construction are connected in series, the dust reduction process is improved to be more intelligent and flexible. For example, multiple environmental dust reduction devices for engineering construction are connected in series in a long area, but only the atomizing sheet 220 near the construction location is started. The switch 230 can be purely mechanical, remote control or sensor type.

[0051] In one embodiment, a dust sensor is provided corresponding to the switch 230 , and the dust sensor is electrically connected to the driving circuit 220 .

[0052] In this embodiment, the switch 230 is controlled to be turned on and off according to the test data of the dust sensor. When the dust sensor obtains a test result that the dust exceeds the standard, the switch 230 is switched to the on state, and the atomizing sheet 220 starts to work; when the dust sensor obtains a test result that the dust meets the standard, the switch 230 is switched to the off state, and the atomizing sheet 220 stops working.

[0053] Reference Figures 1 to 5 In one embodiment, the dust reduction unit 010 further includes a detachable support member 500 , and the support member 500 supports the atomization box 210 on the water tank 100 .

[0054] In this embodiment, considering that the height of dust generated in different construction environments is different, if the height of the dust reduction unit 010 is fixed, the dust reduction effect cannot be optimized. The height of the atomizer box assembly 200 can be adjusted by replacing the support member 500, so as to meet the requirements of different use environments. The connection method of the support member 500, the atomizer box 210 and the water tank 100 can be a snap connection, etc.

[0055] Reference Figure 7 In one embodiment, the height of the support member 500 is adjustable.

[0056] In this embodiment, considering that the construction plane may not be horizontal, the level of the atomizer box assembly 200 cannot be guaranteed. By limiting the support member 500 to be adjustable in height, the level of the atomizer box assembly 200 can be achieved by adjusting the support member 500, so that the atomizer sheet 220 can work normally. The height adjustment method of the support member 500 can be various, such as the support member 500 includes a sub-rod connected by multiple sections of threads, and the length adjustment is formed by changing the degree of thread matching; or the support member 500 includes two sub-rods, the degree of matching between the two sub-rods can be changed, and the locking is achieved by a bolt structure.

[0057] In one embodiment, a level gauge is disposed on the top of the atomizer box 210 .

[0058] In this embodiment, the water state of the atomizer box 210 can be indicated by the level meter, which can also guide the height adjustment of the support member 500. The specific model of the level meter is not limited, as long as it can indicate the horizontal state.

[0059] In one embodiment, the water tank 100 and the atomizer box 210 are an integrated structure.

[0060] In this embodiment, the water tank 100 and the atomizer box 210 are configured as an integrated structure, which reduces the processing difficulty and improves the structural stability.

[0061] In one embodiment, an overflow port is provided at a lower position in the height direction of the atomizer box 210 .

[0062] In this embodiment, the fluid in the atomizer box 210 flows out through the overflow port, and the particulate impurities in the fluid can flow out from the overflow port, thereby ensuring the normal operation of the atomizer sheet 220. It should be noted that the overflow port can only exist in a specific construction environment, otherwise the water flow will have a negative impact on the construction environment.

[0063] In summary, the environmentally friendly dust suppression device for engineering construction provided by the present invention is connected with multiple dust suppression units 010, and the upper parts of the two ends of the water tank 100 in the width direction are provided with a water tank inlet pipe 110 and a water tank outlet pipe 120, so that the water flow can be smoothly driven to flow between the water tanks 100, and the sedimentation process can be naturally completed in the water tank 100, thereby ensuring the operation of the atomizer sheet 220; the atomizer box 210 is provided with an atomizer outlet pipe 213 and an atomizer inlet pipe 212 at both ends in the width direction. When the atomizer inlet pipe 212 and the atomizer outlet pipe 213 are connected, the two atomizer box assemblies 200 The driving circuit 220 is electrically connected, and a plurality of atomizing sheets 220 electrically connected to the driving circuit 220 are arranged at the bottom of the water storage tank 211; the two ends of the return water pipe 200 in the height direction are respectively detachably fixed to the water tank outlet pipe 120 and the atomizing inlet pipe 212, and the water flow can be guided from the last dust reduction unit 010 back to the first dust reduction unit 010 through the return water pipe 200; the environmentally friendly dust reduction device for engineering construction has a simple structure, and the water flow operation can be completed on one side; the atomizing sheet 220 on each dust reduction unit 010 can be started or shut down independently.
