[0001] The utility model relates to the technical field of slag-water separation of shield machines, in particular to a slag-water separation device and a shield machine using the device. Background Art
[0002] Shield machine construction is an important construction method in tunnel engineering. Shield machines construct (lay) the tunnel's "shield" (referring to supporting segments) while excavating. This differs from open-type construction methods. In current construction, after the shield machine removes rock debris, it needs to discharge the debris to make room for operations. Existing shield machines mostly use high-speed, high-pressure water circulation to discharge the debris.
[0003] However, this method places very high demands on the size and quality of the rock debris within the slag. It is unable to distinguish between large and small rock debris for targeted transportation, which results in the accumulation of rock debris in the pipeline, causing blockage and inconvenience in construction. Therefore, it is urgent to design a slag-water separation device and a shield machine using this device to solve the above problems. Utility Model Content

[0024] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.
[0025] like Figure 1-5As shown, the slag-water separation device provided by the embodiment of the present invention and the shield machine using the device include a shield machine and a separation component 7, which is characterized in that the separation component 7 is arranged in the shield machine, the separation component 7 includes a support frame 9, a separation box 10, a first filter plate 15, a second filter plate 16, a drive motor 20 and a cam 21, the separation box 10 is fixedly installed between the support frames 9, and the first filter plate 15 and the second filter plate 16 are fixedly installed with extension plates 25 at both ends. Two mounting grooves 24 are provided on both sides of the inner wall of the separation box 10, and the four extension plates 25 are respectively arranged in the four mounting grooves 24. A plurality of springs 26 are fixedly installed on both sides of the extension plate 25, and a support plate 27 is fixedly installed at one end of the plurality of springs 26. The support plate 27 is fitted with the inner wall of the mounting groove 24, the drive motor 20 is fixedly installed on one side of the separation box 10, and the cam 21 is rotatably installed on one side of the inner wall of the separation box 10. The cam 21 is fixedly connected to the output end of the drive motor 20, and the cam 21 is located between the first filter plate 15 and the second filter plate 16. A sewage collecting chamber 17 is provided at the bottom of the wall, and a box door 12 is rotatably installed on one side of the separation box 10. The box door 12 corresponds to the first filter plate 15 and the second filter plate 16. The first filter plate 15 is located on the upper side of the second filter plate 16. The filter hole diameter of the first filter plate 15 is larger than the filter hole diameter of the second filter plate 16. The second filter plate 16 is located on the upper side of the sewage collecting chamber 17. A first discharge port 22 and a second discharge port 23 are respectively opened on one side of the separation box 10. The first discharge port 22 and the second discharge port 23 are respectively connected to the first filter plate 15 corresponds to the second filter plate 16, a feed port 11 is opened on the upper side of the separation box 10, a mud and water pump 18 is provided on one side of the separation box 10, the output end of the mud and water pump 18 is fixedly connected to the sewage collecting chamber 17, and a conveying pipe 19 is fixedly installed on the output end of the mud and water pump 18. A first belt conveyor 13 and a second belt conveyor 14 are provided between the support frames 9. The first belt conveyor 13 and the second belt conveyor 14 are respectively located at the lower sides of the first discharge port 22 and the second discharge port 23. The length of the first belt conveyor 13 is longer than the length of the second belt conveyor 14.
[0026] Specifically, in this embodiment, through the provided separation assembly 7, when the slag is sent into the separation box 10, it will first fall on the upper side of the first filter plate 15 for screening, and then the driving motor 20 is started to drive the cam 21 to rotate. When the cam 21 rotates, it will squeeze the first filter plate 15 and the second filter plate 16. The first filter plate 15 and the second filter plate 16 are moved by the squeezing force and will be squeezed toward the corresponding spring 26 through the extension plate 25, causing the spring 26 to deform. When the cam 21 stops squeezing the first filter plate 15 and the second filter plate 16, the spring 26 drives the first filter plate 15 and the second filter plate 16 to rebound through the extension plate 25 through its own elastic force, causing the first filter plate 15 and the second filter plate 16 to vibrate, and then the first filter plate 15 and the vibration accelerate the screening of the slag. The larger rock chips in the slag will remain on the first filter plate 15, while the smaller rock chips will remain on the second filter plate 16, and the muddy water will fall into the sewage collection chamber 17. Then, the larger rock chips and the smaller rock chips will slide toward the first discharge port 22 through the inclined setting and vibration of the first filter plate 15 and the second filter plate 16, and then slide onto the first belt conveyor 13 and the second belt conveyor 14 to be sent out of the shield machine. At the same time, by starting the muddy water pump 18, the sewage in the sewage collection chamber 17 can be discharged into the tunnel through the conveying pipe 19. At the same time, an air blowing stirring unit and / or a mechanical stirring unit can be set in the sewage collection chamber 17 to place the mud and sand in the muddy water to settle at the bottom of the sewage collection chamber 17, so that the slag can be fully screened, effectively avoiding the accumulation of rock chips and fragments in the pipeline to cause blockage, affecting construction.
[0027] A sliding groove 28 is provided at the bottom of the inner wall of the installation groove 24 , and a plug post 29 is elastically installed in the sliding groove 28 . A slot is provided on one side of the support plate 27 adjacent to the sliding groove 28 , and the plug post 29 corresponds to the slot.
[0028] In another embodiment provided by the present invention, by providing the plug-in post 29 and the slot, when the first filter plate 15 and the second filter plate 16 need to be replaced, the first filter plate 15 and the second filter plate 16 can be removed by pulling the plug-in post 29 to release the fixed limit of the slot, thereby making it easier for the staff to replace the first filter plate 15 and the second filter plate 16.
[0029] The shield machine includes a shield body 1, a shield machine head 3, a soil bin 5 and a screw conveyor 6. The shield machine head 3 is arranged on one side of the shield body 1. The soil bin 5 and the screw conveyor 6 are both arranged in the shield body 1. The screw conveyor 6 is connected to the soil bin 5. The support frame 9 is arranged in the shield body 1. A conveyor discharge port 8 is provided on one side of the screw conveyor 6, and the conveyor discharge port 8 is fixedly connected to the feed port 11.
[0030] In another embodiment provided by the present invention, a screw conveyor 6 is provided, which can be started to transport the debris in the soil bin 5 and transport the debris to the separation box 10 through the discharge port 8, thereby improving the practicality of the device when used.
[0031] Working principle: After the shield machine has peeled off the rock fragments and needs to discharge the debris, the debris is transported to the separation component 7 through the screw conveyor 6. The separation component 7 performs multi-stage screening on the debris, and separates the larger rock fragments, smaller rock fragments, and mud water in the debris. The debris is then discharged using different methods, effectively avoiding the accumulation of rock fragments in the pipeline to cause blockage and affect construction.
