Description

Technical Field

[0001] The invention belongs to the technical field of tunnel construction, and in particular relates to a harmful gas treatment device for TBM tunneling. Background Art

[0002] TBM tunneling refers to a method of tunnel construction using a tunnel boring machine. TBM is a large mechanical device specially designed for tunneling underground. It forms tunnels by cutting soil and rock, and installs tunnel linings while excavating to ensure the stability of the structure. TBM tunneling may produce some harmful gases, such as carbon monoxide, hydrogen sulfide and other harmful gases, as well as particulate matter such as dust, which requires emergency treatment at any time.

[0003] The Chinese patent with application number 202320973431.0 provides an automatic treatment device for harmful gases in a tunnel, including: a filter box, a clean air box, an air pump and a stirring mechanism. The filter box is placed on a support to raise the position; the clean air box is placed on the ground adjacent to the filter box, and the clean air box contains toxic gas solution; the filter box and the clean air box are both opened upward to expose the entire box cavity, and a barrier plate is placed on the top of the box cavity; the air pump and the filter box are placed on the support, the air intake of the air pump is connected to the box cavity of the filter box, and the air outlet of the air pump is connected to the box cavity of the clean air box; the stirring mechanism is arranged in the clean air box, and the stirring blades of the stirring mechanism are immersed in the toxic gas solution in the clean air box. This patent can simultaneously treat dust and carbon monoxide in a short time, with high efficiency and good use effect, will not delay the tunnel construction period, can reasonably control the content of dust and carbon monoxide in the tunnel, and eliminate potential threats to the physical safety of tunnel workers.

[0004] When treating dust and harmful gases at the same time, if a filter structure with better filtering performance is used, it is easy to cause blockage of the filter structure, resulting in the device being unable to perform subsequent harmful gas treatment; if a filter structure with larger filter holes is used, the ventilation effect can be guaranteed, but some dust will be allowed to follow into the treatment liquid, resulting in too much dust accumulation inside the subsequent box containing the treatment liquid, causing the box to be blocked and difficult to clean.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] (1) The present invention uses an air intake fan to suck air containing harmful gases and dust into a regulating box, and adjusts the air intake direction through an adjusting mechanism, so that the dust is collected by the ash storage tank and the harmful gases enter the liquid storage tank for treatment. While the harmful gases are treated, the dust is fully filtered and collected, thereby avoiding the problem of excessive dust entering the liquid storage tank, causing blockage and difficulty in cleaning. Specifically, when the upper and lower ends of the two filter plates are respectively in contact with the partition plate and the ash storage tank, one of the closing plates closes one side, and the partition plate, the ash storage tank and the filter slot form two filter chambers. At this time, the second vent is connected to the first vent above the small slot between the two filter plates. The air containing harmful gases and dust enters between the two filter plates from the square tube, the second vent, and the first vent, and is filtered by one of the filter plates and then discharged from the side not closed by the closing plate. After the dust is filtered and intercepted, part of it falls into the ash storage tank and is collected. The air containing harmful gases is sucked into the liquid storage tank by a micro air pump for treatment, thereby avoiding the problem of excessive dust entering the liquid storage tank, causing blockage and difficulty in cleaning.

[0023] (2) The present invention cooperates with the adjustment mechanism and the adjustment box. When a certain amount of dust adheres to the filter plate, it is easy to get clogged, thus affecting the filtering effect. At this time, the filter slot is controlled to move by the electric telescopic rod, so that one of the sealing plates can be released and the other sealing plate can be closed, and the two filter plates are adjusted in position. At this time, the air containing harmful gases and dust will change the air intake direction, enter from the other first air vent and be filtered from the new filter plate. After filtration, the air containing harmful gases is discharged from the side that is not closed by the sealing plate into the new liquid storage tank, thereby quickly solving the problem of filter plate clogging. Moreover, after adjusting the air intake direction, the filter plate with dust adhered is located under the middle partition plate and will be blown in the opposite direction by the air, blowing the dust adhered to the filter plate into the ash storage tank to automatically clean the filter plate. This can not only quickly solve the problem of filter plate clogging, but also automatically clean the filter plate, while ensuring that the equipment can work in a cycle without stopping.

[0024] (3) The present invention adopts the structural design of the ash storage trough to make the ash storage trough a detachable structure. When the ash storage trough needs to be installed, the ash storage trough body is plugged into the through hole at the bottom of the regulating box body, and then the hook is hung on the corresponding hanging rod; when the ash storage trough needs to be disassembled for ash unloading, the hook is removed and the bottom plate is slid down along the second slide groove; this structural design can also assist in deep cleaning of the filter plate. When the dust adhered to the filter plate cannot be automatically cleaned after a long period of use, the ash storage trough is disassembled and slid down, and then the filter plate is moved to the corresponding first air vent under the control of the electric telescopic rod. At this time, the second air vent is connected with the two first air vents. The operation of the air intake fan can simultaneously blow air to the two filter plates and the interior of the regulating box body, thereby achieving deep cleaning. While cleaning the dust, the ash unloading operation of the ash storage trough can be facilitated. BRIEF DESCRIPTION OF THE DRAWINGS
