DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0019] In order to solve the technical problem of how to improve the speed of building a dust suppression atomization system for tunnel construction, the present invention provides a tunnel construction dust suppression atomization system. The above-mentioned tunnel construction dust suppression atomization system can quickly build a supporting structure of the atomizing nozzle 230 by inflation, thereby improving the speed of building the tunnel construction dust suppression atomization system.

[0020] 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, etc. For the convenience of explanation, in the present invention, only the application of the tunnel construction dust suppression atomization system to tunnel construction is used as an example for explanation, and the principle of applying the tunnel construction dust suppression atomization system to other types of equipment is essentially the same as the principle applied to tunnel construction, which will not be repeated here.

[0021] See also Figure 1 , Figure 1 The structure diagram of the tunnel construction dust suppression atomization system in one embodiment of the present invention is shown in FIG. The tunnel construction dust suppression atomization system includes a support assembly 100 and an atomization assembly 200. The support assembly 100 includes an inflatable beam 110 and an air pump 120. The inflatable beam 110 has a first state in which the internal gas is filled and expanded and fits the inner wall of the tunnel, and has a second state in which the internal gas is emptied to shrink the inflatable beam 110. The air pump 120 is connected to the inflatable beam 110, and the inflatable beam 110 is controlled by the air pump 120 to switch between the first state and the second state. The atomization assembly 200 includes a water pump 210, a water supply pipe 220, and a plurality of atomization nozzles 230. The plurality of atomization nozzles 230 are arranged on the inflatable beam 110. The water supply pipe 220 is respectively connected to the water pump 210 and the plurality of atomization nozzles 230. The water pump 210 presses water into the water supply pipe 220 so that the atomization nozzles 230 spray water mist.

[0022] In this embodiment, firstly, the air pump 120 is used to fill the air into the inflatable beam 110, so that the inflatable beam 110 is switched from the second state to the first state, so that the inflatable beam 110 fits the inner wall of the tunnel. Since the atomizing nozzle 230 is arranged on the inflatable beam 110, the atomizing nozzle 230 can be set up near the inner wall of the tunnel, and the water pump 210 sprays water to the atomizing nozzle 230 through the water supply pipe 220, and finally water mist can be sprayed in the tunnel to suppress dust. The above-mentioned tunnel construction dust suppression atomization system can quickly build the support structure of the atomizing nozzle 230 by means of inflation, and its construction process is simple and fast, which improves the rapidity of building the tunnel construction dust suppression atomization system.

[0023] In some of the embodiments, the atomization assembly 200 further includes a water tank 240 , and a water inlet end of the water pump 210 is connected to the water tank 240 .

[0024] In this embodiment, the water tank 240 is used to store water, and the water inlet end of the water pump 210 is connected to the water tank 240. The water pump 210 can extract the water stored in the water tank 240, and then the water pump 210 pressurizes the water to the water supply pipe.

[0025] It should be noted that in order to obtain a more ideal atomization effect, in some embodiments, the atomization component 200 also includes a medicine tank, which stores an active surfactant. The medicine tank introduces the active surfactant into the water tank 240, and the water and the active surfactant are mixed with each other to form an atomized liquid. The atomized 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, thereby obtaining a more ideal atomization effect.

[0026] In some embodiments, the atomizing assembly 200 further includes a filter 250 , which is installed at the water inlet end of the water pump 210 .

[0027] In this embodiment, since the filter 250 is installed at the water inlet end of the water pump 210 , it can effectively prevent impurities in the water tank 240 from entering the water supply pipe 220 , thereby preventing the impurities from clogging the atomizing nozzle 230 .

[0028] Any embodiment of the filter 250 that can filter impurities is feasible. In some embodiments, the filter 250 includes a plurality of stacked filter screens.

[0029] In this embodiment, impurities in the water are filtered layer by layer through stacked filter screens, thereby obtaining a more ideal filtering efficiency.

[0030] In some embodiments, one end of the water supply pipe 220 away from the water pump 210 is connected to the water tank 240 .

[0031] 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 .

[0032] In some embodiments, the atomizing assembly 200 includes a regulating valve 260 , which is installed at one end of the water supply pipe 220 away from the water pump 210 . The pressure in the water supply pipe 220 is adjusted by adjusting the opening of the regulating valve 260 .

[0033] In this embodiment, since the flow rate of the water pump 210 pressurized water remains stable, the flow rate of the water supply pipe 220 returning to the 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 changing the atomization pressure of the water mist sprayed by the atomizing nozzle 230.

[0034] Based on the above embodiments, in some of the embodiments, the water supply pipe 220 includes a plurality of unit pipes 221 and a plurality of three-way joints 222, the plurality of three-way joints 222 are connected to a plurality of atomizing nozzles 230 one by one, the plurality of unit pipes 221 are arranged at intervals between the plurality of three-way joints 222, and the two ends of the unit pipe 221 are respectively connected to two adjacent three-way joints 222.

[0035] In some embodiments, the unit tube 221 and the three-way connector 222 are connected by quick-connection.

[0036] In this embodiment, since the unit tube 221 and the three-way joint 222 are connected by a quick-insert connection, the unit tube 221 and the three-way joint 222 can be quickly connected or disassembled with each other, so as to facilitate the rapid disassembly and assembly between the unit tube 221 and the three-way joint 222.

[0037] In some of the embodiments, the contact surface between the inflatable beam 110 and the tunnel is provided with an anti-skid and wear-resistant layer.

[0038] In this embodiment, the protective wear-resistant layer is in direct contact with the inner wall of the tunnel. 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 friction coefficient between the inflatable beam 110 and the inner wall of the tunnel, increase the friction between the inflatable beam 110 and the inner wall of the tunnel, and prevent the inflatable beam 110 from tipping over.

[0039] In some of the embodiments, a side of the inflatable beam 110 facing away from the anti-slip and wear-resistant layer has a cable tie, and the cable tie is used to tie the water supply pipe 220 so that the water supply pipe 220 and the inflatable beam 110 are connected to each other.

[0040] In this embodiment, the water supply pipe 220 and the air-filled beam 110 are bundled together by a cable tie, so that the air-filled beam 110 supports the water supply pipe 220 .

[0041] In some embodiments, a plurality of atomizing nozzles 230 are arranged along the length direction of the inflatable beam 110 .

[0042] In this embodiment, since the plurality of atomizing nozzles 230 are arranged along the length direction of the air-filled beam 110 , the atomizing nozzles 230 can spray into a larger tunnel space.

[0043] In order to better understand the present invention, the following Figures 1 to 3 The technical solution of the present invention is described in detail: First, the air pump 120 is used to fill the air in the inflatable beam 110, so that the inflatable beam 110 switches from the second state to the first state, so that the inflatable beam 110 fits the inner wall of the tunnel, and the inflatable beam 110 supports the strength of the water supply pipe 220 through the air volume, and is fixed to prevent tipping under the action of the anti-skid wear-resistant layer of the inflatable beam. Since the atomizing nozzle 230 is set on the side of the inflatable beam 110 away from the tunnel wall through the water supply pipe 220, the atomizing nozzle 230 can face the space inside the tunnel, the water tank 240 is used to store the atomized liquid, and the water inlet end of the water pump 210 is connected to the water tank 240. The water pump 210 can extract the atomized liquid in the water tank 240, and then the water pump 210 sends the atomized liquid to the water supply pipe 220, and finally the bubble mist can be sprayed in the tunnel to suppress dust. The above-mentioned tunnel construction dust suppression atomization system can quickly build the support structure of the atomizing nozzle 230 by inflation. Compared with the traditional support structure that needs to be disassembled and assembled, its construction process is simple, fast and easy to move.

[0044] The specific implementation of the present invention described above does not constitute a limitation on the protection scope of the present invention. Any other corresponding changes and modifications made based on the technical concept of the present invention should be included in the protection scope of the claims of the present invention.
