Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of tunnel construction equipment, in particular to a tunnel construction wastewater recycling system and a use method thereof. BACKGROUND

[0002] In the construction of tunnel engineering, water pollution problems are prone to occur due to the need for deep underground tunneling, especially in some southern regions where groundwater systems are relatively abundant. In this case, the construction of underground tunnels will pollute and damage groundwater. When wastewater is discharged without treatment, it will harm surface water bodies and human health. In specific tunnel construction, common methods include explosive blasting, piling, concrete pouring, and reinforcement, which can affect the surrounding rock walls of the tunnel. When the cement on the rock falls off, it will produce a large amount of slurry, causing water pollution and threatening the safety of the construction team during underground construction. A wastewater recycling system is usually used to purify and treat wastewater for recycling.

[0003] In the prior art, when wastewater is extracted, the sediment and large particles in the wastewater are prone to accumulate at the extraction location due to the suction force, affecting the extraction efficiency. Moreover, when the wastewater is purified, the impurities are prone to block the filtration equipment when the wastewater concentration is too high, affecting the normal filtration work of the equipment and resulting in low filtration efficiency. At the same time, when clean water is extracted, the sediment from the purification process is easily extracted, affecting the purification quality. Therefore, it is necessary to design a tunnel construction wastewater recycling system and a use method thereof. SUMMARY

[0016] A use method of a tunnel construction wastewater recycling system, comprising the following steps:

[0017] Step S1: The load-bearing support and the anti-skid base plate at the bottom of the load-bearing support can provide stable support for the load-bearing frame; during use, the first water pump on the side of the installation tank cover is operated, and the wastewater is extracted through the wastewater pipe and the water inlet assembly; one end of the wastewater pipe is placed in the wastewater, the water suction seat is supported by the support bracket, so that the wastewater can be filtered by the inclined filter plate and then transported to the first water pump through the wastewater pipe; during the extraction of the wastewater, large particles and sediments in the water are also extracted to one side of the inclined filter plate; at this time, the first motor at the top of the pollution discharging shell is operated, and one of the connecting shafts is driven to rotate between the transmission bearings through the motor shaft; since the belt pulleys are fixed to the outer sides of the connecting shafts and the two belt pulleys are connected by the transmission belt, one belt pulley drives the other belt pulley to rotate; the rotating transmission belt drives the discharge plate to rotate; when the discharge plate rotates to the inside of the water suction seat, the discharge plate can wind and scrape off the large particles and sediments from one side of the inclined filter plate; after the sediments and large particles are wound into the inside of the pollution discharging shell, they fall out of the pollution discharging shell through the discharge hole; when there are many sediments at the bottom of the pollution discharging shell, the first electric guide rail is operated, so that the first electric slide moves at the outer side of the first electric guide rail, thereby the anti-blocking pusher is driven by the vertical beam frame to move the sediments, effectively avoiding the blockage of the discharge hole caused by the accumulation of many sediments;

[0018] Step S2: the wastewater extracted by the first water pump is conveyed to the inside of the circulating water tank through the pipeline, and is purified by the purification assembly; when the wastewater is conveyed to the inside of the impurity removal box of the purification box through the pipeline, the wastewater can be subjected to secondary filtration and purification by the first purification filter element and the second purification filter element, so that the purified wastewater is located on one side of the second filter pipe; in the process of purification, the impurity removal box is fixedly installed on one side of the purification box through the connecting seat, so that the impurity removal box has a stable connection structure; the vibrator at the bottom of the impurity removal box works to vibrate the inside of the impurity removal box, so that the impurities adhering to the surfaces of the first purification filter element and the second purification filter element are shaken off, the efficiency of purification and filtration is improved, the distance between the first purification filter element and the second purification filter element can be adjusted according to the different concentrations of impurities in the wastewater, so that the first purification filter element and the second purification filter element are not blocked by too many impurities, and the normal filtration of the first purification filter element and the second purification filter element is affected; the second electric guide rail works to drive the second electric sliding seat to move on the outside of the second electric guide rail, so that the distance between the first purification filter element and the second purification filter element is adjusted through the adjusting bracket at the top of the second electric sliding seat and the adjusting bracket at the top of the follower plate, so that the distance between the first purification filter element and the inner wall on one side of the impurity removal box and the distance between the second purification filter element and the inner wall on the other side of the impurity removal box are adjusted; when it is necessary to adjust the distance between the first purification filter element and the second purification filter element, the second motor at the bottom of the second electric sliding seat works to drive the adjusting gear to rotate; with the rotation of the adjusting gear, the adjusting tooth plate is pushed to slide in the limiting hole; the follower plate drives the guide block to slide in the guide groove at the top of the second electric guide rail, so that the follower plate drives the adjusting bracket and the second purification filter element to move, thereby adjusting the distance between the second purification filter element and the first purification filter element; by setting different distances between the second purification filter element and the first purification filter element, wastewater with different concentrations can be filtered;

[0019] Step S3: the third water pump works to convey the water purified by the second purification filter element to the second filter pipe through the first filter pipe, and then to the inside of the sedimentation tank through the second filter pipe for storage, and meanwhile, the ultraviolet disinfection lamp at the bottom of the sealing partition plate works to sterilize the water in the sedimentation tank and the impurity removal box; after a period of sedimentation, the fourth water pump works, and meanwhile, according to the depth of the sedimentation water, the third electric guide rail works to drive the positioning frame to move the folding pipe by the third electric sliding seat, so that one end of the bottom of the folding pipe is inserted below the liquid level of the sedimentation tank, and the fourth water pump conveys the water in the sedimentation tank to the top of the sealing partition plate through the pipeline for storage, so that the second water pump on the top of the water pump support can conveniently extract clean water from the inside of the circulating water tank through the pipeline, and the clean water can be conveniently recycled.

[0020] The beneficial effects of this invention are as follows: The tunnel construction wastewater recycling system of this invention is simple to operate and has multiple functions. During use, the water inlet component set at one end of the wastewater pipe has a good anti-accumulation and clogging function, effectively avoiding the situation where sediment accumulation prevents water pumping. At the same time, the purification component has a good purification and filtration function, and can adjust the distance between the filter elements according to different concentrations of wastewater, so that the volume can be adjusted, thereby avoiding the filter elements from being clogged by excessively high concentrations, thus affecting the purification efficiency. In addition, by setting one end of the filter pipe above the sediment, it is easy to pump out clean water and avoids pumping out sediment impurities, effectively improving the quality of water pumping and facilitating recycling.

The water suction seat 61 is fixedly installed at one end of the bottom of the wastewater pipe 5, and the bottom end of the water suction seat 61 is fixedly installed with the support bracket 63. The inner bottom of the water suction seat 61 is fixedly installed with the inclined filter plate 62. The outer end face of the water suction seat 61 is insertedly installed with the sewage machine shell 64 on one side, and the inner part of the sewage machine shell 64 communicates with the inner part of the water suction seat 61. The inner wall of the sewage machine shell 64 is provided with the belt pulley 68 on both sides of the center, and the outer side of the two belt pulleys 68 is sleeved with the transmission belt 69. The end face of the transmission belt 69 is fixedly installed with a plurality of discharge plates 610, and one end of the discharge plate 610 passes through the sewage machine shell 64, the water suction seat 61 and is located on the outer side of the inclined filter plate 62. One end of the discharge plate 610 is of a conical structure. The bottom end face of the sewage machine shell 64 is provided with the discharge hole 615 below the discharge plate 610, and the anti-blocking push seat 614 is arranged below the discharge hole 615. The top and bottom end faces of the sewage machine shell 64 are fixedly installed with two transmission bearings 65, and the connecting shaft 66 is insertedly installed between the two transmission bearings 65. The belt pulley 68 is fixedly installed on the outer wall center of the connecting shaft 66. The first motor 67 is fixedly installed on one side of the top of the sewage machine shell 64, and the motor shaft of the first motor 67 is fixedly connected with one of the connecting shafts 66. The outer wall of the sewage machine shell 64 is fixedly installed with the first electric guide rail 611 on both sides of the center, and the first electric guide rail 611 is connected and installed with the first electric sliding seat 612 on the outer side. The vertical beam frame 613 is fixedly installed on both ends of the center of the anti-blocking push seat 614, and the other end of the two vertical beam frames 613 is fixedly connected with the first electric sliding seat 612. The wastewater pipe 5 and the water inlet assembly 6 can extract wastewater, effectively avoid that large-particle impurities and sediments in the water are also stacked on one side of the inclined filter plate 62, and affect water pumping.

[0041] The working principle of the present application is that the load-bearing legs and the anti-skid base plates at the bottom of the load-bearing legs can provide stable support for the load-bearing frame 1. During use, the first water pump 4 on one side of the installation tank cover 3 is operated to extract waste water through the waste water pipe 5 and the water inlet assembly 6. One end of the waste water pipe 5 is placed in the waste water, and the water suction seat 61 is supported by the support bracket 63, so that the waste water can be filtered by the inclined filter plate 62 and then delivered to the first water pump 4 through the waste water pipe 5. During the extraction of waste water, large particles and sediments in the water are also extracted to one side of the inclined filter plate 62. At this time, the first motor 67 at the top of the sewage discharging shell 64 is operated to drive one of the connecting shafts 66 to rotate between the transmission bearings 65 through the motor shaft. Since the pulleys 68 are fixed to the outer side of the connecting shaft 66, and the two pulleys 68 are connected by a transmission belt 69, one pulley 68 drives the other pulley 68 to rotate. The rotating transmission belt 69 drives the discharge plate 610 to rotate. When the discharge plate 610 rotates to the inside of the water suction seat 61, the discharge plate 610 can wind and scrape off large particles and sediments from one side of the inclined filter plate 62. After the sediments and large particles are wound into the inside of the sewage discharging shell 64, they fall out of the sewage discharging shell 64 through the discharge hole 615. When the bottom of the sewage discharging shell 64 is filled with more sediments, the first electric guide rail 611 is operated to move the first electric sliding seat 612 outside the first electric guide rail 611, so that the anti-blocking push seat 614 can be driven by the vertical beam frame 613 to move the sediments, effectively preventing the discharge hole 615 from being blocked by too many sediments. The waste water extracted by the first water pump 4 is delivered to the circulating water tank through the pipeline.The interior of the second purification filter core 77 is purified by the purification assembly 7. When the wastewater is transported to the interior of the impurity removal box 72 of the purification box 71 through the pipeline, the wastewater can be twice filtered and purified by the first purification filter core 76 and the second purification filter core 77, so that the purified wastewater is located on one side of the second filter pipe 714. In the purification process, the impurity removal box 72 is fixedly installed on one side of the purification box 71 through the connecting seat 722, so that the impurity removal box 72 has a stable connecting structure. The vibrator 723 at the bottom of the impurity removal box 72 works to vibrate the interior of the impurity removal box 72, so that the impurities adhering to the surfaces of the first purification filter core 76 and the second purification filter core 77 are shaken off, the efficiency of purification and filtration is improved, the distance between the first purification filter core 76 and the second purification filter core 77 can be adjusted according to the different concentrations of impurities in the wastewater, so that the first purification filter core 76 and the second purification filter core 77 are prevented from being blocked by too many impurities, so as to affect the normal filtration treatment of the first purification filter core 76 and the second purification filter core 77. The second electric guide rail 73 works to drive the second electric sliding seat 74 to move on the outer side of the second electric guide rail 73, so that the distance between the first purification filter core 76 and the second purification filter core 77 is adjusted through the adjusting bracket 75 at the top of the second electric sliding seat 74 and the adjusting bracket 75 at the top of the follow-up plate 712, so that the distance between the first purification filter core 76 and the inner wall on one side of the impurity removal box 72 and the distance between the second purification filter core 77 and the inner wall on the other side of the impurity removal box 72 are adjusted. When it is necessary to adjust the distance between the first purification filter core 76 and the second purification filter core 77, the second motor 710 at the bottom of the second electric sliding seat 74 works to drive the adjusting gear 711 to rotate. With the rotation of the adjusting gear 711, the adjusting tooth plate 79 is pushed to slide in the limiting hole 78. The follow-up plate 712 drives the guide block to slide in the guide groove at the top of the second electric guide rail 73, so that the follow-up plate 712 drives the adjusting bracket 75 and the second purification filter core 77 to move, thereby adjusting the distance between the second purification filter core 77 and the first purification filter core 76. Different distances between the second purification filter core 77 and the first purification filter core 76 are set, so that wastewater with different concentrations can be filtered.The third water pump 715 works to transport the water purified by the second purification filter 77 to the second filter pipe 714 through the first filter pipe 713, and then to the inside of the sediment tank 724 through the second filter pipe 714. Meanwhile, the ultraviolet disinfection lamp 721 at the bottom of the sealing partition plate 8 works to sterilize the water in the sediment tank 724 and the impurity removal box 72. After a period of sedimentation, the fourth water pump 720 works, and according to the depth of the sediment water, the third electric guide rail 716 works to drive the positioning frame 718 to pull the folding pipe 719 to move, so that one end of the bottom of the folding pipe 719 is inserted below the liquid level of the sediment tank 724, and the fourth water pump 720 transports the water in the sediment tank 724 to the top of the sealing partition plate 8 through the pipeline, so that the second water pump 9 at the top of the water pump support can extract the purified water from the inside of the circulating water tank 2 through the pipeline, facilitating recycling.

[0042] A method for using a tunnel construction wastewater recycling system, comprising the following steps:

[0043] Step S1: The load support feet and the anti-skid base plates at the bottom of the load support feet can provide stable support for the load frame 1. When in use, the first water pump 4 on one side of the installation tank cover 3 works to extract wastewater through the wastewater pipe 5 and the water inlet assembly 6. One end of the wastewater pipe 5 is placed in the wastewater, and the support bracket 63 supports the water suction seat 61, so that the wastewater can be filtered by the inclined filter plate 62 and then transported to the first water pump 4 through the wastewater pipe 5. In the process of extracting wastewater, large particles and sediments in the water are also extracted to one side of the inclined filter plate 62. At this time, the first motor 67 at the top of the sewage removal shell 64 works to rotate one of the connecting shafts 66 between the transmission bearings 65 through the motor shaft. Since the belt pulleys 68 are fixed to the outside of the connecting shafts 66, and the two belt pulleys 68 are connected by the transmission belt 69, one of the belt pulleys 68 drives the other belt pulley 68 to rotate. The rotating transmission belt 69 drives the discharge plate 610 to rotate. When the discharge plate 610 rotates to the inside of the water suction seat 61, the discharge plate 610 can wind and scrape off the large particles and sediments from one side of the inclined filter plate 62. After the sediments and large particles are wound into the inside of the sewage removal shell 64, they fall out of the sewage removal shell 64 through the discharge hole 615. When the bottom of the sewage removal shell 64 is filled with a large amount of sediments, the first electric guide rail 611 works to move the first electric sliding seat 612 outside the first electric guide rail 611, so that the anti-blocking push seat 614 can be driven by the vertical beam frame 613 to move the sediments, effectively preventing the discharge hole 615 from being blocked by a large amount of sediments.

[0044] Step S2: the wastewater extracted by the first water pump 4 is conveyed to the inside of the circulating water tank through the pipeline, and is purified by the purification assembly 7. When the wastewater is conveyed to the inside of the impurity removal box 72 of the purification box 71 through the pipeline, the wastewater can be twice filtered and purified by the first purification filter element 76 and the second purification filter element 77, so that the purified wastewater is located on one side of the second filter pipe 714. In the process of purification, the impurity removal box 72 is fixedly installed on one side of the purification box 71 through the connecting seat 722, so that the impurity removal box 72 has a stable connecting structure. The vibrator 723 at the bottom of the impurity removal box 72 works to vibrate the inside of the impurity removal box 72, so as to shake off the impurities adhering to the surfaces of the first purification filter element 76 and the second purification filter element 77, improve the efficiency of purification and filtration, and adjust the distance between the first purification filter element 76 and the second purification filter element 77 according to the different concentrations of impurities in the wastewater, so as to avoid that the first purification filter element 76 and the second purification filter element 77 are blocked by too many impurities, thereby affecting the normal filtration treatment of the first purification filter element 76 and the second purification filter element 77. The second electric guide rail 73 works to drive the second electric sliding seat 74 to move on the outside of the second electric guide rail 73, so as to adjust the distance between the first purification filter element 76 and the second purification filter element 77 through the adjusting supports 75 at the top of the second electric sliding seat 74 and the adjusting supports 75 at the top of the follower plate 712, so as to adjust the distance between the first purification filter element 76 and the inner wall on one side of the impurity removal box 72 and the distance between the second purification filter element 77 and the inner wall on the other side of the impurity removal box 72. When it is necessary to adjust the distance between the first purification filter element 76 and the second purification filter element 77, the second motor 710 at the bottom of the second electric sliding seat 74 works to drive the adjusting gear 711 to rotate. With the rotation of the adjusting gear 711, the adjusting tooth plate 79 is pushed to slide in the limiting hole 78. The follower plate 712 drives the guide block to slide in the guide groove at the top of the second electric guide rail 73, so that the follower plate 712 drives the adjusting supports 75 and the second purification filter element 77 to move, thereby adjusting the distance between the second purification filter element 77 and the first purification filter element 76. By setting different distances between the second purification filter element 77 and the first purification filter element 76, wastewater with different concentrations can be filtered and treated;

[0045] Step S3: the third water pump 715 works, and the water purified by the second purification filter 77 can be transported to the second filter pipe 714 through the first filter pipe 713, and then transported to the inside of the sediment tank 724 through the second filter pipe 714. At the same time, the ultraviolet disinfection lamp 721 at the bottom of the sealing partition plate 8 works, and the water in the sediment tank 724 and the impurity removal box 72 can be sterilized. After a period of sedimentation, the fourth water pump 720 works. At the same time, according to the depth of the sediment water, the third electric guide rail 716 works, the third electric sliding seat 717 drives the positioning frame 718 to pull the folding pipe 719 to move, so that one end of the bottom of the folding pipe 719 is inserted below the liquid level of the sediment tank 724, so that the fourth water pump 720 transports the water in the sediment tank 724 to the top of the sealing partition plate 8 through the pipeline for storage, so that the second water pump 9 on the top of the water pump support can extract the purified water from the inside of the circulating water tank 2 through the pipeline, and the water can be conveniently recycled.

[0046] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art can make equivalent replacements or changes according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered by the protection scope of the present application.

10. A method for using a tunnel construction wastewater recycling system, characterized in that, Includes the following steps: Step S1: The load-bearing legs and the anti-slip pads at the bottom of the load-bearing legs provide stable support for the load-bearing frame. During use, the first water pump on the side where the tank cover is installed operates, drawing wastewater through the wastewater pipe and inlet assembly. One end of the wastewater pipe is placed in the wastewater, and the suction seat is supported by the support bracket, allowing the wastewater to be filtered through the inclined filter plate and then transported to the first water pump through the wastewater pipe. During the wastewater extraction process, large particles and sediments in the water are also drawn to one side of the inclined filter plate. At this time, the first motor on the top of the sewage discharge casing operates, driving one of the connecting shafts to rotate between the transmission bearings via the motor shaft. Since the pulley is fixed on the outside of the connecting shaft, The two pulleys are connected by a transmission belt, which drives the other pulley to rotate. The rotating transmission belt drives the discharge plate to rotate. When the discharge plate rotates to the inside of the water suction seat, it can wrap around large particles of impurities and sediments and scrape them off from one side of the inclined filter plate. The sediments and large particles of impurities are rolled into the inside of the sewage discharge casing and fall out of the sewage discharge casing through the discharge hole. When a lot of sediments accumulate at the bottom of the sewage discharge casing, the first electric guide rail works, which moves the first electric slide outside the first electric guide rail. This allows the anti-clogging pusher to push the sediments away through the vertical beam frame, effectively preventing the accumulation of sediments from clogging the discharge hole. Step S2: Wastewater pumped by the first water pump is transported through pipelines to the interior of the circulating water tank, where it undergoes purification treatment by the purification components. After the wastewater is transported through the pipeline to the impurity removal box of the purification chamber, it undergoes secondary filtration through the first and second purification filter elements. This ensures the purified wastewater is located on one side of the second filter tube. During the purification process, the impurity removal box is fixedly installed on one side of the purification chamber via a connecting seat, providing a stable connection structure. The vibrator at the bottom of the impurity removal box vibrates the interior, shaking off impurities adhering to the surfaces of the first and second purification filter elements, improving filtration efficiency. The distance between the first and second purification filter elements can be adjusted according to the different concentrations of impurities in the wastewater, preventing excessive impurities from clogging the first and second purification filter elements and affecting their normal filtration. The second electric guide rail operates, carrying... The second electric slide moves outside the second electric guide rail, thereby adjusting the distance between the first and second purification filter elements through the adjusting brackets on the top of the second electric slide and the adjusting brackets on the top of the follower plate. This allows for adjustment of the distance between the first purification filter element and one side of the inner wall of the impurity removal box, and the distance between the second purification filter element and the other side of the inner wall of the impurity removal box. When it is necessary to adjust the distance between the first and second purification filter elements, the second motor at the bottom of the second electric slide works, driving the adjusting gear to rotate. As the adjusting gear rotates, it pushes the adjusting tooth plate to slide inside the limiting hole. The follower plate drives the guide block to slide inside the guide groove on the top of the second electric guide rail, causing the follower plate to move the adjusting bracket and the second purification filter element, thereby adjusting the distance between the second and first purification filter elements. By setting different distances between the second and first purification filter elements, different concentrations of wastewater can be filtered. Step S3: The third water pump operates, transporting the water purified by the second purification filter through the first filter tube to the second filter tube, and then through the second filter tube to the sedimentation tank for storage. Simultaneously, the ultraviolet disinfection lamp at the bottom of the sealed partition sterilizes the water in the sedimentation tank and the impurity removal box. After a period of sedimentation, the fourth water pump operates. At the same time, based on the depth of the sedimented water, the third electric guide rail operates, driving the positioning frame to move the folded tube through the third electric slide, so that one end of the folded tube is inserted below the liquid surface in the sedimentation tank. This allows the fourth water pump to transport the water in the sedimentation tank through the pipe to the top of the sealed partition for storage, thus facilitating the second water pump at the top of the water pump bracket to draw clean water from the inside of the circulating water tank through the pipe for easy recycling.
