Description

Technical Field

[0001] This utility model relates to the field of tunnel boring machine technology, specifically to a sewage treatment device for tunnel boring machines. Background Technology

[0002] A tunnel boring machine (TBM) is a specialized engineering machine that uses the shield tunneling method for tunnel excavation. Unlike open-face construction, it constructs (lays) the tunnel's "shield" (i.e., supporting segments) while excavating to maintain the stability of the excavation face. A TBM mainly consists of a front cutting ring, a middle support ring, and a rear shield tail. The overall structure is a cylindrical steel component. It integrates optical, mechanical, electrical, hydraulic, sensor, and information technologies and has multiple functions such as excavating and cutting soil, transporting excavated material, assembling tunnel lining, and measuring, guiding, and correcting deviations.

[0003] In tunnel excavation, tunnel boring machines (TBMs) play a crucial role, but their continuous advancement generates a significant problem—the production of large amounts of wastewater. This wastewater is complex, containing mud, sand, foaming agents, and various suspended solids. The mud makes the wastewater viscous, the presence of sand increases the particulate matter content, the foaming agents not only alter the physical state of the wastewater but may also contain environmentally harmful chemical components, and the suspended solids further exacerbate the turbidity. If this wastewater is discharged directly without treatment, it will have serious negative impacts on the environment.

[0004] Therefore, a sewage treatment device for tunnel boring machines is proposed. Utility Model Content

[0033] Furthermore, in this embodiment, the wastewater is initially filtered by the filter plate 53 inside the treatment chamber 2 to remove larger particulate impurities. Flocculant is added to the feed seat 56 and enters the treatment chamber 2 51 through the feed pipe 57. The motor 58 is started, and its output shaft drives the rotating rod 59 to rotate, which in turn drives the stirring frame 510 to rotate, stirring the wastewater in the treatment chamber 2 51 and promoting the coagulation of fine particles in the wastewater into larger particles.

Example

[0034] Please see Figures 1-4Furthermore, based on Embodiment 1, the following is obtained: the collection unit includes a collection rack 61, which is located inside the processing chamber 2 and is slidably connected to the inner wall of the processing chamber 2. A collection rack 62 is provided at the right end of the collection rack 61, which is located inside the processing chamber 2 51 and is slidably connected to the inner wall of the processing chamber 2 51. The upper end of the collection rack 62 is fixedly connected to the fixing plate 55.

[0035] The adjustment part includes a connecting plate 63. There are two connecting plates 63 arranged at the front and rear. The two connecting plates 63 are fixedly connected to the upper end of the first collection rack 61 and the upper end of the second collection rack 62 at their close ends.

[0036] A support rod 64 is fixedly installed on the bottom surface of the rear connecting plate 63. A support sleeve 65 is fitted on the lower end of the support rod 64.

[0037] Furthermore, in this embodiment, the first collection rack 61 and the second collection rack 62 collect the impurities intercepted on the first filter plate 53 and the second filter plate 54. The hydraulic cylinder 66 is activated, and its output shaft drives the front connecting plate 63 to move up or down. Since the two connecting plates 63 are fixedly connected to the upper ends of the first collection rack 61 and the second collection rack 62, the first collection rack 61 and the second collection rack 62 will move up and down with the movement of the connecting plate 63, which facilitates the removal of the collected impurities and makes it easier to clean the impurities in the future.

[0038] Furthermore, in this embodiment, the first collection rack 61 and the second collection rack 62 can move up and down via the connecting plate 63, the support rod 64, the support sleeve 65, and the hydraulic cylinder 66, thereby conveniently collecting impurities on the filter plate and carrying them out of the processing chamber, reducing the difficulty and workload of manual cleaning, and improving cleaning efficiency.

[0039] During operation, the wastewater generated by the tunnel boring machine enters treatment chamber 2 from the inlet seat 3. The filter plate 53 inside treatment chamber 2 performs preliminary filtration, removing larger particles and impurities. The filtered wastewater then enters treatment chamber 51 through the connecting pipe 52. The filter plate 54 inside treatment chamber 51 further filters the wastewater. Flocculant is added to the feed seat 56 and enters treatment chamber 51 through the feed pipe 57. The motor 58 starts, and its output shaft drives the rotating rod 59 to rotate, which in turn drives the mixing frame 510 to rotate, thus purifying the wastewater in treatment chamber 51. The system stirs the wastewater to promote the aggregation of fine particles into larger particles. The first collection rack 61 and the second collection rack 62 collect the impurities intercepted on the first filter plate 53 and the second filter plate 54. The hydraulic cylinder 66 is activated, and its output shaft drives the front connecting plate 63 to move up or down. Since the two connecting plates 63 are fixedly connected to the upper ends of the first collection rack 61 and the second collection rack 62, the first collection rack 61 and the second collection rack 62 will move up and down with the movement of the connecting plate 63, which facilitates the removal of the collected impurities and makes it easier to clean the impurities later.
