Description

Technical Field

[0001] This invention relates to the field of dust removal equipment technology, specifically to an energy-saving and environmentally friendly tunnel dust removal device for civil engineering construction. Background Technology

[0002] Tunnels are engineering structures buried in the earth's strata and represent a form of human utilization of underground space.

[0003] In existing technologies, the drill-and-blast method is often used for tunnel construction. Because the drill-and-blast method involves trackless muck removal and transportation, dust generated during blasting operations and shotcrete spraying, as well as dust generated by vehicles traveling and operating, permeates the area from the tunnel entrance to the tunnel face. In particular, the dust generated near the excavation face causes low visibility and poor air quality, which can cause certain harm to workers.

[0004] Existing technologies often employ spray dust suppression vehicles for dust control at construction sites. However, due to the limited space inside tunnels, parking these spray dust suppression vehicles severely restricts the area of ​​the construction site.

[0005] Traditional dust suppression spray vehicles use a high-pressure pump to pressurize water. The high-pressure water then passes through a high-pressure atomizing nozzle to produce a water mist with a diameter similar to that of dust particles. The water mist then quickly adsorbs and condenses with the dust particles, causing them to grow larger and settle under their own gravity, thus achieving the purpose of dust suppression. Therefore, traditional dust suppression spray vehicles consume a large amount of water and are not energy-efficient. Summary of the Invention

[0006] To address the aforementioned problems, this invention provides an energy-saving and environmentally friendly tunnel dust removal device for civil engineering construction.

[0007] The design scheme of the present invention is as follows: an energy-saving and environmentally friendly tunnel dust removal device for civil engineering construction, comprising a transportation unit and a dust removal unit disposed on the transportation unit; the dust removal unit comprises a main module and a sub-module connected to the main module;

[0008] The main body module includes a housing disposed on the transport unit, a first dust removal main body and a second dust removal main body disposed inside the housing, and a connecting unit disposed on the side wall of the housing;

[0009] The sub-module includes a movable frame that can be movably placed on the conveying unit, and a first dust removal sub-body and a second dust removal sub-body respectively placed on the movable frame;

[0010] The first dust removal main body includes a storage tank for storing dust removal liquid and a high-pressure atomizing host connected to the storage tank;

[0011] The first dust removal mother body includes a dust removal body and a negative pressure unit connected to the dust removal body;

[0012] The connection unit includes a first connection component connected to the high-pressure atomizing host and a second connection component connected to the negative pressure unit;

[0013] The second dust removal sub-body includes a first branch system disposed on the movable frame and connected to the first connecting assembly, and 2 to 4 first sub-modules respectively connected to the first branch system; the first sub-module includes a spray assembly, a first folding bracket for supporting the spray assembly, and a first branch assembly for connecting the spray assembly and the first branch system.

[0014] The second dust removal sub-body includes a second branch system disposed on the movable frame and connected to the second connecting assembly, and 5 to 20 second sub-modules respectively connected to the second branch system; the second sub-module includes a negative pressure dust box, a second folding bracket for supporting the negative pressure dust box, and a second branch assembly for connecting the negative pressure dust box and the second branch system.

[0015] Furthermore, the transportation unit includes a first transportation vehicle body and a self-unloading unit disposed on the first transportation vehicle body; the parent module is disposed on the first transportation vehicle body, and the child module can be placed on the self-unloading unit.

[0016] Note: The self-unloading unit is used to place the sub-modules and facilitates loading and unloading of the sub-modules; in actual use, the first transport vehicle is parked in the original construction site area, and then the sub-modules are unloaded before use.

[0017] Furthermore, the self-unloading unit includes a mounting base disposed on the first transport vehicle body, a hydraulic cylinder assembly mounted on the mounting base at one end, and a lifting plate disposed at the other end of the hydraulic cylinder assembly;

[0018] The hydraulic cylinder assembly includes a lifting cylinder for controlling the lifting of the lifting plate and a steering cylinder for controlling the tilting of the lifting plate; the movable frame can be placed on the lifting plate and is connected by a locking mechanism.

[0019] Note: The self-unloading unit with this structure can more easily load and unload the sub-modules; and the locking mechanism connects the sub-modules to the lifting plate, which is more conducive to the stability during transportation.

[0020] Furthermore, the transport unit includes a second transport vehicle body and a tractor body connected to the rear of the second transport vehicle body; the mother module is disposed on the second transport vehicle body, and the daughter module can be placed on the tractor body.

[0021] Note: The installation of the sub-module is achieved by using a towing vehicle, which eliminates the need for loading and unloading. The module is simply moved to the designated location and then towed and placed. This method is not only convenient for transportation but also relatively low in cost, making it more suitable for widespread adoption.

[0022] Furthermore, the dust removal body includes a dust removal box, a dust removal channel disposed inside the dust removal box and connected to the negative pressure unit, and a plurality of dust removal sub-modules that are connected one by one to the dust removal channel and are equipped with solenoid valves at the connection points.

[0023] The dust removal submodule includes a temporary storage chamber located inside the dust removal box and connected at one end to the dust removal channel, a dust collection drawer snapped into the temporary storage chamber and located at the lower end of the temporary storage chamber, an air outlet located at the other end of the temporary storage chamber, a filter screen located inside the temporary storage chamber and located at the air outlet, and a switch valve located on the air outlet.

[0024] Description: The dust from the construction site is drawn into the temporary storage chamber by a vacuuming mechanism, and then filtered through a filter screen to retain the dust in the dust collection drawer. In actual use, a 'dust suction path' can be created when the solenoid valve and the switching valve are opened simultaneously. Multiple dust collection sub-modules can be used in batches, and the dust collection drawers of the used dust collection sub-modules can be cleaned promptly while other dust collection sub-modules are in use.

[0025] Furthermore, the first connecting component and the second connecting component have the same structure, and both the first connecting component and the second connecting component include a pipe winch and a connecting pipe that can be wound around the pipe winch; the connecting pipe of the first connecting component is a flexible water pipe; the connecting pipe of the second connecting component is a flexible dust suction duct.

[0026] Note: Pipe winches can be used to wind connecting pipes. When not in use, the connecting pipes can be neatly wound and unwound for connection when needed. This can effectively increase the distance between transport vehicles and the construction site, and effectively avoid the area restriction caused by transport vehicles parking on the construction site.

[0027] Furthermore, the first folding bracket includes a counterweight box, a folding frame that can be snapped onto the counterweight box, a plurality of extension rods with one end threaded onto the folding frame, and a movable retaining ring disposed at the other end of the extension rod and capable of movably snapping onto the spray assembly.

[0028] Instructions: When in use, you can place sand, gravel, soil or other counterweights from the construction site into the counterweight box to increase stability. When not in use, empty the counterweights, disassemble the sprinkler assembly and the first folding bracket, place them in the counterweight box, and then place the counterweight box on the mobile frame and secure it.

[0029] Furthermore, the spray assembly includes a spray pipe with multiple atomizing nozzles; the spray pipe can be movably engaged with the movable retaining ring.

[0030] Note: The structure of the spray pipe can be assembled on-site according to the construction site. It can be assembled into a straight line or a square shape, thereby adjusting the spray direction of the atomizing nozzle.

[0031] Furthermore, the second folding bracket includes a built-in support leg installed at the bottom of the negative pressure dust box, an external support leg disposed on the side wall of the negative pressure dust box, and a support rod threaded onto the built-in support leg for installing the second branch assembly.

[0032] Note: The use of built-in and external support legs can effectively increase the stability of the overall structure of the second sub-module; and the built-in and external support legs are connected by a connecting shaft to realize the flipping and folding of the built-in and external support legs.

[0033] Furthermore, both the built-in support leg and the external support leg are telescopic structures.

[0034] Note: The telescopic structure allows for space saving after folding, making it easy to place the second sub-module inside the mobile frame.

[0035] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0036] 1) The overall structure of this invention is reasonably designed. It uses a first dust removal mother body and a first dust removal daughter body to construct a dust removal method, and uses a second dust removal mother body and a second dust removal daughter body to construct another dust removal method. In actual use, it can be selectively used according to the air quality standards of the construction site to achieve energy saving and environmental protection.

[0037] 2) This invention utilizes a separate setup of the main module and the sub-modules, which are connected by a connecting unit. This effectively places the transport unit in an area far from the construction site, avoiding the area restrictions imposed on the construction site by the transport unit.

[0038] 3) This invention utilizes an assembly structure of multiple first sub-modules and multiple second sub-modules to achieve flexible combination and use for different construction sites. It can not only effectively reduce dust, but also be more environmentally friendly and energy-saving due to the targeted regional layout restrictions on the construction site.
