Description

Technical Field

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

[0002] A large amount of dust is generated during tunnel construction, which can be suppressed by releasing water mist through a tunnel atomization system.

[0003] Existing tunnel atomization systems can be found in patent publication CN108678800B, which discloses a tunnel curing dust removal device and method. It includes a portal frame and an arched mist supply pipe arranged internally and externally. The arched mist supply pipe is connected to the portal frame via support rods, and several evenly spaced spray heads are installed on the arched mist supply pipe. The water mist sprayed from the spray heads can then suppress dust. However, the aforementioned tunnel atomization system requires the construction of a support structure for the spray heads, and the disassembly and assembly of this support structure is extremely cumbersome and requires a significant amount of manpower.

[0004] Therefore, improving the speed of setting up a dust suppression atomization system for tunnel construction is an urgent technical problem to be solved. Summary of the Invention

[0005] The purpose of this invention is to overcome the above-mentioned technical deficiencies and propose a tunnel construction dust suppression atomization system to solve the technical problems of slow disassembly and assembly and poor mobility of existing tunnel construction dust suppression atomization systems.

[0006] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution:

[0007] This invention provides a dust suppression atomization system for tunnel construction, comprising:

[0008] A support assembly includes an inflatable beam and an air pump. The inflatable beam has a first state in which it is filled with gas and inflated to fit against the inner wall of the tunnel, and a second state in which it deflates by venting the gas. The air pump is connected to the inflatable beam and controls the switching of the inflatable beam between the first and second states.

[0009] The atomizing assembly includes a water pump, a water supply pipe, and a plurality of atomizing nozzles. The plurality of atomizing nozzles are disposed on the air-filled beam. The water supply pipe is connected to the water pump and the plurality of atomizing nozzles respectively. The water pump pressurizes water into the water supply pipe so that the atomizing nozzles spray water mist.

[0010] In some embodiments, the atomizing assembly further includes a water tank, and the water inlet of the water pump is connected to the water tank.

[0011] In some embodiments, the atomizing assembly further includes a filter installed at the inlet of the water pump.

[0012] In some embodiments, the end of the water supply pipe away from the water pump is connected to the water tank.

[0013] In some embodiments, the atomizing assembly includes a regulating valve installed between the end of the water supply pipe away from the water pump and the water tank, and the pressure in the water supply pipe is adjusted by regulating the opening of the valve.

[0014] In some embodiments, the filter comprises a plurality of stacked filter screens.

[0015] In some embodiments, the water supply pipe includes multiple unit pipes and several T-joints, with each of the T-joints corresponding to one of the atomizing nozzles. The multiple unit pipes are spaced apart between the T-joints, and each unit pipe is connected to two adjacent T-joints at both ends.

[0016] In some embodiments, the unit tube and the tee connector are connected by a quick-connect fitting.

[0017] In some embodiments, the inflatable beam is provided with an anti-slip and wear-resistant layer on the contact surface with the tunnel.

[0018] In some embodiments, the side of the inflatable beam opposite to the anti-slip and wear-resistant layer has a cable tie, which is used to tie the water supply pipe so that the water supply pipe is connected to the inflatable beam.

[0019] First, air is pumped into the inflatable beam, switching it from a second state to a first state, allowing it to conform to the tunnel's inner wall. Since the atomizing nozzles are positioned on the inflatable beam, they can be mounted close to the tunnel wall. A water pump supplies water to the nozzles through a water supply pipe, ultimately spraying water to suppress dust within the tunnel. This tunnel construction dust suppression atomizing system allows for rapid assembly of the nozzle support structure via air inflation. Compared to traditional support structures that require disassembly and reassembly, its assembly process is simpler and faster, significantly improving the speed of setting up the tunnel construction dust suppression atomizing system.

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0025] To address the technical problem of improving the speed of setting up a dust suppression atomization system for tunnel construction, this invention provides a dust suppression atomization system for tunnel construction. The aforementioned dust suppression atomization system for tunnel construction can quickly build the support structure of the atomizing nozzle 230 by inflating it, thereby improving the speed of setting up the dust suppression atomization system for tunnel construction.

[0026] It should be noted that the tunnel construction dust suppression atomization system of the present invention is used for, but not limited to, tunnel construction. For ease of explanation, this invention will only use the application of the tunnel construction dust suppression atomization system in tunnel construction as an example. The principle of the tunnel construction dust suppression atomization system applied to other types of equipment is essentially the same as that applied to tunnel construction, and will not be described in detail here.

[0027] Please see Figure 1 , Figure 1 This is a schematic diagram of a tunnel construction dust suppression atomization system according to an embodiment of the present invention. The tunnel construction dust suppression atomization system includes a support component 100 and an atomization component 200. The support component 100 includes an inflatable beam 110 and an air pump 120. The inflatable beam 110 has a first state in which it is filled with gas and expands to fit against the inner wall of the tunnel, and a second state in which it empties the gas to shrink. The air pump 120 is connected to the inflatable beam 110 and controls the switching of the inflatable beam 110 between the first and second states. The atomization component 200 includes a water pump 210, a water supply pipe 220, and a plurality of atomizing nozzles 230. The plurality of atomizing nozzles 230 are disposed on the inflatable beam 110. The water supply pipe 220 is connected to the water pump 210 and the plurality of atomizing nozzles 230 respectively. The water pump 210 pressurizes water into the water supply pipe 220 so that the atomizing nozzles 230 spray water mist.

[0028] In this embodiment, gas is first filled into the inflatable beam 110 by the air pump 120, switching the inflatable beam 110 from a second state to a first state, so that the inflatable beam 110 fits against the inner wall of the tunnel. Since the atomizing nozzle 230 is set on the inflatable beam 110, the atomizing nozzle 230 can be mounted close to the inner wall of the tunnel. The water pump 210 sprays water to the atomizing nozzle 230 through the water supply pipe 220, and finally, water mist can be sprayed inside the tunnel to suppress dust. The above-mentioned tunnel construction dust suppression atomizing system can quickly build the support structure of the atomizing nozzle 230 by inflation. Its construction process is simple and fast, improving the speed of building the tunnel construction dust suppression atomizing system.

[0029] In some embodiments, the atomizing assembly 200 also includes a water tank 240, with the water inlet of the water pump 210 connected to the water tank 240.

[0030] In this embodiment, the water tank 240 is used for water storage, and the water inlet of the water pump 210 is connected to the water tank 240. The water pump 210 can draw water from the water tank 240 and then pump the water pressure to the water supply pipe.

[0031] It should be noted that, in order to obtain a more ideal atomization effect, in some embodiments, the atomizing component 200 also includes a reagent tank, which stores an active surface agent. The active surface agent is introduced into the water tank 240 from the reagent tank. The water and the active surface agent are mixed to form an atomizing liquid. The atomizing liquid is sprayed through the atomizing nozzle 230 to form a bubble mist, which increases the residence time of the bubble droplets in the air, thereby increasing the probability of the bubble droplets capturing dust, thus obtaining a more ideal atomization effect.

[0032] In some embodiments, the atomizing assembly 200 further includes a filter 250, which is installed at the inlet of the water pump 210.

[0033] In this embodiment, since the filter 250 is installed at the water inlet of the water pump 210, it can effectively prevent impurities in the water tank 240 from entering the water supply pipe 220, thus avoiding impurities from clogging the atomizing nozzle 230.

[0034] Any implementation of the filter 250 that can filter impurities is feasible. In some embodiments, the filter 250 includes multiple stacked filter screens.

[0035] In this embodiment, impurities in the water are filtered layer by layer through stacked filter screens, thereby achieving a more ideal filtration efficiency.

[0036] In some embodiments, the end of the water supply pipe 220 away from the water pump 210 is connected to the water tank 240.

[0037] In this embodiment, since the end of the water supply pipe 220 away from the water pump 210 is connected to the water tank 240, excess water in the water supply pipe 220 can flow back to the water tank 240.

[0038] In some embodiments, the atomizing assembly 200 includes a regulating valve 260, which is installed at the end of the water supply pipe 220 away from the water pump 210, and the opening of the regulating valve 260 is adjusted to adjust the pressure in the water supply pipe 220.

[0039] In this embodiment, since the flow rate of the water pump 210 pressurizes the water flow to remain stable, the flow rate in the water supply pipe 220 and the return water tank 240 can be changed by changing the opening of the regulating valve 260, thereby changing the pressure in the water supply pipe 220 and thus changing the atomization pressure of the water mist sprayed by the atomizing nozzle 230.

[0040] Based on the above embodiments, in some embodiments, the water supply pipe 220 includes multiple unit pipes 221 and several tee connectors 222, the several tee connectors 222 are connected to several atomizing nozzles 230 in a one-to-one correspondence, the multiple unit pipes 221 are spaced apart between the several tee connectors 222, and the two ends of the unit pipe 221 are respectively connected to two adjacent tee connectors 222.

[0041] In some embodiments, the unit tube 221 and the tee connector 222 are connected by a quick-connect fitting.

[0042] In this embodiment, since the unit tube 221 and the tee connector 222 are connected by quick-connect, the unit tube 221 and the tee connector 222 can be quickly connected or disconnected from each other, so as to facilitate quick assembly and disassembly between the unit tube 221 and the tee connector 222.

[0043] In some embodiments, the inflatable beam 110 has an anti-slip and wear-resistant layer on the contact surface with the tunnel.

[0044] In this embodiment, the protective wear-resistant layer is in direct contact with the tunnel inner wall. On the one hand, the protective wear-resistant layer has good wear resistance, which can prevent the inflatable beam 110 from being damaged by friction. On the other hand, it can increase the coefficient of friction between the inflatable beam 110 and the tunnel inner wall, increase the frictional force between the inflatable beam 110 and the tunnel inner wall, and prevent the inflatable beam 110 from tipping over.

[0045] In some embodiments, the side of the inflatable beam 110 facing away from the anti-slip and wear-resistant layer has a cable tie, which is used to bind the water supply pipe 220 so that the water supply pipe 220 is connected to the inflatable beam 110.

[0046] In this embodiment, the water supply pipe 220 and the inflatable beam 110 are tied together with cable ties, so that the inflatable beam 110 supports the water supply pipe 220.

[0047] In some embodiments, a plurality of atomizing nozzles 230 are arranged along the length of the inflatable beam 110.

[0048] In this embodiment, since multiple atomizing nozzles 230 are arranged along the length of the inflatable beam 110, the atomizing nozzles 230 can spray into a larger tunnel space.

[0049] To better understand this invention, the following is combined with... Figures 1 to 3 The technical solution of the present invention will be described in detail below:

[0050] First, air is pumped into the inflatable beam 110 using air pump 120, switching the beam from a second state to a first state. This allows the inflatable beam 110 to conform to the inner wall of the tunnel. The amount of air used provides the beam with the strength to support the water supply pipe 220, while the anti-slip and wear-resistant layer of the beam prevents it from tipping over. Since the atomizing nozzle 230 is positioned on the side of the inflatable beam 110 away from the tunnel wall via the water supply pipe 220, it faces the tunnel interior. The water tank 240 stores the atomizing liquid, and the inlet of the water pump 210 is connected to the water tank 240. The pump 210 draws the atomizing liquid from the tank and then pumps it to the water supply pipe 220, ultimately spraying atomized mist to suppress dust within the tunnel. The aforementioned tunnel construction dust suppression atomization system can quickly build the support structure for the atomizing nozzle 230 by inflating it. Compared with traditional support structures that require disassembly and reassembly, its construction process is simple, fast, and easy to move.

[0051] The specific embodiments of the present invention described above do not constitute a limitation on the scope of protection of the present invention. Any other corresponding changes and modifications made in accordance with the technical concept of the present invention should be included within the scope of protection of the claims of the present invention.
