Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of tunnel construction, and particularly relates to a harmful gas treatment device for TBM tunneling. BACKGROUND

[0002] TBM tunneling refers to a method of tunnel construction by a tunnel boring machine. TBM is a large mechanical equipment specially designed for tunnel excavation underground. It forms a tunnel by cutting soil and rock, and installs a tunnel lining while tunneling to ensure the stability of the structure. Some harmful gases may be produced during TBM tunneling, such as carbon monoxide, hydrogen sulfide and other harmful gases, and particulate matter such as dust may also be produced, which needs to be treated in an emergency at any time.

[0003] The Chinese patent with application number 202320973431.0 provides a tunnel harmful gas automatic treatment device, which comprises a filter box, a clean gas box, a gas pump and a stirring mechanism. The filter box is placed on a support to raise the position. The clean gas box is placed adjacent to the filter box on the ground, and the clean gas box contains a toxic gas dissolving liquid. The filter box and the clean gas box are both upwardly open to expose the entire box cavity, and a blocking plate is placed on the top of the box cavity. The gas pump is placed on the support together with the filter box. The suction port of the gas pump is connected to the box cavity of the filter box, and the gas outlet of the gas pump is connected to the box cavity of the clean gas box. The stirring mechanism is arranged in the clean gas box, and the stirring blade of the stirring mechanism is immersed in the toxic gas dissolving liquid in the clean gas box. The patent can simultaneously treat dust and carbon monoxide in a short time, has high efficiency, good use effect, does not delay the tunnel construction period, can reasonably control the content of dust and carbon monoxide in the tunnel, and eliminates the potential threat to the physical safety of tunnel workers.

[0004] When dust and harmful gases are treated at the same time, if a filter structure with good filtering performance is used, the filter structure is easy to be blocked, causing the device to be unable to perform subsequent harmful gas treatment. If a filter structure with a larger filter hole is used, the ventilation effect can be ensured, but part of the dust will enter the treatment liquid, causing the inside of the box containing the treatment liquid to accumulate too much dust, resulting in blockage of the box and difficulty in cleaning.

[0040] The application realizes that the dust is collected by the ash storage tank 600 and the harmful gas enters the liquid storage tank 200 to be treated, and at the same time, the dust is fully filtered and collected, so that the problem of blockage and difficult cleaning of the liquid storage tank 200 caused by too much dust is avoided.

[0041] It is worth noting that the treatment liquid in the liquid storage tank 200 can be sodium hydroxide solution, which can treat hydrogen sulfide and other harmful gases generated in the TBM tunneling process, and different treatment liquids can be selected according to actual conditions, so that different harmful gases can be treated specifically, which will not be described in detail here.

[0042] Further, the adjusting box 100 comprises an adjusting box body 110, the top of the adjusting box body 110 is fixedly connected with a square tube 120, and the air inlet fan 700 is installed at the top end of the square tube 120; two first air vents 170 are formed through the top of the adjusting box body 110, and the first air vents 170 are located in the square tube 120; the air containing harmful gas and dust is sucked into the square tube 120 from the outside by the air inlet fan 700 and enters the inside of the adjusting box body 110 from the first air vents 170;

[0043] The inside top wall of the adjusting box body 110 is fixedly provided with three partition plates 180 at equal distances, and the two first air vents 170 are located between the corresponding adjacent partition plates 180; the adjacent partition plates 180 and the inner wall of the adjusting box body 110 form a partition groove; the top of the ash storage tank 600 is provided with two ash storage tank openings 620, and the ash storage tank openings 620 are located directly below the partition grooves corresponding to the partition plates 180.

[0044] Further, the adjusting mechanism comprises a filter slot 400 and a switching plate 300; the filter slot 400 is located between the partition plate 180 and the ash storage tank 600, and the top and bottom of the filter slot 400 are open, and the inside of the filter slot 400 is fixedly connected with two filter plates 410 at equal distances; the left and right sides of the filter slot 400 are both closed plates 420, and the closed plates 420 and the filter plates 410 divide the filter slot 400 into three small slots with the same size;

[0045] The front and rear sides of the filter slot 400 are attached to the inner wall of the adjusting box body 110; the slot sizes of the small slots, the ash storage tank openings 620 and the partition grooves are the same.

[0046] Further, the two sides of the square tube 120 are provided with sliding openings 130, the top of the adjusting box body 110 is fixedly provided with a sliding groove 160, the two ends of the sliding groove 160 are communicated with the corresponding sliding openings 130, and the first air vents 170 are located in the sliding groove 160; the switching plate 300 is slidably connected with the sliding groove 160, a second air vent 310 is throughly provided on the switching plate 300, and the caliber of the second air vent 310 is larger than that of the first air vent 170. The switching plate 300 is slid on the sliding groove 160 to selectively close one of the first air vents 170.

[0047] Further, the side wall of the adjusting box body 110 is fixedly provided with an electric telescopic rod 430, the telescopic end of the electric telescopic rod 430 penetrates through the adjusting box body 110 and the end of the telescopic end is fixedly connected with one of the closing plates 420; the side, away from the electric telescopic rod 430, of the adjusting box body 110 is provided with a C-shaped connecting rod 440, one end of the C-shaped connecting rod 440 penetrates through the side wall of the adjusting box body 110 and the end is fixedly connected with the other closing plate 420, and the other end of the C-shaped connecting rod 440 is fixedly connected with one end of the switching plate 300; the electric telescopic rod 430 is used for controlling the movement of the filtering slot 400, and under the connection of the C-shaped connecting rod 440, the switching plate 300 moves together with the filtering slot 400;

[0048] It is worth noting that the electric telescopic rod 430, the air inlet fan 700 and the micro air pump 141 are all controlled by an external power supply, which will not be described in detail here.

[0049] When the upper and lower ends of the two filtering plates 410 are respectively abutted with the partition plates 180 and the ash storage grooves 600, the second air vent 310 is communicated with the first air vent 170 above the small slot between the two filtering plates 410, the switching plate 300 closes the other first air vent 170, and the upper and lower ends of one of the closing plates 420 are respectively abutted with the corresponding partition plates 180 and the ash storage grooves 600.

[0050] Specifically, as Figure 5As shown, when the upper and lower ends of the two filter plates 410 respectively abut against the sealing plate 180 and the ash storage tank 600, one of the sealing plates 420 closes one side, and the sealing plate 180, the ash storage tank 600 and the filter channel 400 form two filter chambers. At this time, the second vent 310 is connected to the first vent 170 located above the small channel between the two filter plates 410. Air containing harmful gases and dust enters between the two filter plates 410 from the square tube 120, the second vent 310 and the first vent 170. After being filtered by one of the filter plates 410, it is discharged from the side that is not closed by the sealing plate 420. After the dust is filtered and intercepted, part of it falls into the ash storage tank 600 and is collected. The air containing harmful gases is drawn into the liquid storage tank 200 by the micro air pump 141 and treated, thereby avoiding the problem of excessive dust entering the liquid storage tank 200, which would cause blockage and make it difficult to clean.

[0051] like Figure 6 As shown in state 2, when the filter plate 410 is located directly below the corresponding first vent 170, the second vent 310 is connected to both first vents 170.

[0052] like Figure 6 As shown in state 1, the present invention, through the cooperation of the adjustment mechanism and the adjustment box 100, addresses the issue that when dust adheres to the filter plate 410, it is prone to clogging, thus affecting the filtration effect. At this time, the electric telescopic rod 430 controls the movement of the filter channel 400, allowing one of the sealing plates 420 to be released and the other sealing plate 420 to be closed. The two filter plates 410 are then repositioned. This causes the air containing harmful gases and dust to change its intake direction, entering through another first vent 170 and being filtered by the new filter plate 410. The filtered air then contains harmful gases... The air from the side not sealed by the sealing plate 420 is discharged into the new liquid storage tank 200, thereby quickly solving the problem of filter plate 410 clogging. Furthermore, after adjusting the air intake direction, the filter plate 410 with adhering dust is located below the middle sealing plate 180 and will be blown by the reverse airflow, blowing the dust adhering to the filter plate 410 into the ash storage tank 600 to achieve automatic cleaning of the filter plate 410. This not only quickly solves the problem of filter plate 410 clogging, but also automatically cleans the filter plate 410, while ensuring that the equipment can operate continuously without stopping.

[0053] Furthermore, the ash storage trough 600 includes an ash storage trough body 610, and the bottom of the regulating box body 110 is provided with an opening, the ash storage trough body 610 being inserted into the opening at the bottom of the regulating box body 110; the top of the ash storage trough body 610 is provided with two ash storage openings 620, the bottom of the ash storage trough body 610 is fixedly provided with a base plate 611, the two sides of the base plate 611 are fixedly provided with connecting frames 640, the connecting frames 640 are fixedly mounted with a rotating shaft 641, the rotating shaft 641 is rotatably connected with a hook 650, and the side wall of the regulating box body 110 is correspondingly fixedly provided with a hanging rod 150; when the hook 650 is hooked with the corresponding hanging rod 150, the base plate 611 abuts against the bottom of the regulating box body 110.

[0054] The present invention makes the ash storage trough 600 a detachable structure through the structural design of the ash storage trough 600. When the ash storage trough 600 needs to be installed, the ash storage trough body 610 is inserted into the opening at the bottom of the regulating box body 110, and then the hook 650 is hung on the corresponding hanging rod 150.

[0055] Furthermore, a movable ash trough 630 is inserted into the ash storage trough opening 620, and a sealing strip is provided on the top of the outer edge of the base plate 611. The movable ash trough 630 is easy to disassemble and unload ash, and the sealing strip can further improve the sealing performance.

[0056] Furthermore, a base frame 500 is fixedly installed at the bottom of the regulating box body 110. The base frame 500 includes a base 510, on which two support plates 520 are vertically fixed. The support plates 520 are fixedly connected to the bottom of the regulating box body 110, and the support plates 520 are located between the ash storage tank 600 and the corresponding liquid storage tank 200. A second sliding groove 530 is fixedly provided on the side of the support plate 520 near the ash storage tank 600, and the base plate 611 is slidably connected to the second sliding groove 530.

[0057] like Figure 6 As shown in state 2, when it is necessary to disassemble the ash storage tank 600 for ash discharge, remove the hook 650 and let the bottom plate 611 slide down along the second slide groove 530. This structural design can also assist in deep cleaning of the filter plate 410. When the dust adhering to the filter plate 410 cannot be automatically cleaned after a long period of use, the ash storage tank 600 is disassembled and slid down. Then, by controlling the electric telescopic rod 430, the filter plate 410 is moved to the position directly below the corresponding first vent 170. At this time, the second vent 310 is connected to both first vents 170. By operating the air intake fan 700, air can be blown into both filter plates 410 and the interior of the regulating box body 110 at the same time, thereby achieving deep cleaning. While cleaning the dust, it can also facilitate the ash discharge operation of the ash storage tank 600.

[0058] Further, the liquid storage tank 200 is provided with a plurality of exhaust ports 230 above the sidewall away from the ash storage tank 600, one sidewall of the liquid storage tank 200 is provided with a liquid inlet pipe 210 in communication, the bottom of the liquid storage tank 200 is provided with a liquid outlet pipe 220 in communication, and the liquid inlet pipe 210 and the liquid outlet pipe 220 are both provided with valves. The treated gas is discharged from the exhaust port, the liquid outlet pipe 220 can discharge the invalid treatment liquid, and the liquid inlet pipe 210 can add new treatment liquid.

[0059] It should be noted that, by cooperating the adjusting mechanism with the adjusting tank 100, the problem of the filter plate 410 being blocked can be quickly solved, the filter plate 410 can be automatically cleaned, the liquid storage tank 200 can be automatically switched, the old liquid storage tank 200 can be replaced with new treatment liquid in idle time, and the comprehensive guarantee of the equipment circulating work without shutdown is realized.

[0061] The above is only the preferred embodiment of the present application, and it should be noted that, for those skilled in the art, several improvements and changes can be made without departing from the inventive concept, and these are within the protection scope of the present application.
