Description

Technical Field

[0001] This application relates to the field of wastewater treatment, and in particular to a device for purifying and recycling wastewater from tunnel drilling construction. Background Technology

[0002] Currently, the main excavation technology for tunnel construction is still the drill-and-blast method, given the confined space inside tunnels. However, with improvements in the drill-and-blast method, single-arm, double-arm, and even triple-arm drilling rigs have gradually replaced the manual drilling process using 28# pneumatic drills. This has the advantages of increased drilling efficiency, improved working environment, and enhanced safety, but it also places higher demands on supporting construction facilities. In this context, the hydraulic drill-and-blast method using drilling rigs requires a large amount of water and generates significant amounts of construction wastewater. This wastewater typically contains high concentrations of suspended solids, oil, heavy metals, and total nitrogen residues from blasting. Water quality and quantity fluctuate significantly depending on geological conditions and the stage of construction. Traditional sedimentation tanks and simple filtration equipment are unable to handle sudden water inrushes or high sediment loads, easily becoming clogged and exhibiting low treatment efficiency, resulting in unstable effluent quality.

[0003] Patent document CN212833167U discloses a wastewater purification and recycling device, including a support plate. A filter shell is fixedly connected to one side of the top of the support plate, and an inlet is connected to one side of the top of the filter shell. Two symmetrically distributed connecting blocks are fixedly connected to the top of the inside of the filter shell, and a sludge filter screen is fixedly connected between the two symmetrically distributed connecting blocks. This device not only accelerates the wastewater treatment speed and allows for faster discharge of treated wastewater, preventing the device from being clogged by sludge, but also treats wastewater more thoroughly, meeting people's usage requirements.

[0004] However, the aforementioned wastewater purification and recycling device has the disadvantages of being unable to separate oil from wastewater during treatment, resulting in insufficient wastewater treatment, and being unable to automatically feed materials, thus failing to flocculate and settle the wastewater. Therefore, we propose a wastewater purification and recycling device for tunnel drilling construction to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as the inability to separate oil from wastewater during treatment, resulting in insufficient wastewater treatment, and the inability to automatically feed materials, which prevents wastewater from flocculating and settling.

The oil floats to the sides of the filter box and is then adsorbed by the oil adsorption layer.

[0028] 2. This solution can automatically add materials, enabling flocculation and sedimentation of wastewater. The half-gear drives the rectangular toothed frame to move, which in turn drives the sliding plate to move. The sliding plate opens the bottom of the storage tank, allowing the flocculant in the storage tank to fall into the sedimentation tank. It can automatically add flocculant after the wastewater enters the sedimentation tank, facilitating the sedimentation of the wastewater. Attached Figure Description

After purification, the water is connected to the backup water storage tank through the water delivery pipeline, thus forming a closed-loop water circulation system.

[0066] The implementation principle of the wastewater purification and recycling device for tunnel drilling construction in this application embodiment is as follows: First, a portion of the wastewater is discharged into the filter box 2 through the inlet pipe 3. The wastewater entering the filter box 2 is filtered through the filter screen 6, which allows larger impurities in the wastewater to be screened out. The filter screen 6 is in an inclined state in the filter box 2, so that the wastewater will not leak out through the outlet 4 after entering the filter box 2. Then, the wastewater falls to the bottom of the filter box 2. The motor 8 is started, and the motor 8 drives the first drive shaft 9 to rotate. The first drive shaft 9 drives the stirring blade 10 to rotate. The stirring blade 10 agitates the wastewater, causing the wastewater to rotate and generate centrifugal force, thereby separating the oil floating on the wastewater from the wastewater. The oil floats to the periphery of the filter box 2 and is absorbed by the oil adsorption layer 7. Simultaneously, after the wastewater enters the filter tank 2, the float 11 floats according to the water level, thereby driving the first connecting rod 12 to move. The first connecting rod 12 drives the second connecting rod 13 to move, and the second connecting rod 13 drives the rack 14 to move. When the float 11 floats at a low position, the rack 14 cannot mesh with the gear 15. While filtering the wastewater and separating the oil, the first drive shaft 9 drives the first sprocket 32 ​​to rotate. The first sprocket 32 ​​drives another first sprocket 32 ​​to rotate via the first chain 33. The first sprocket 32 ​​drives the fourth drive shaft 31 to rotate. The fourth drive shaft 31 drives the rotating plate 35 to rotate. The rotating plate 35 drives the rotating block 36 to rotate. The rotating block 36 drives the crank 37 to swing, and the crank 37 drives the rotating shaft 38 to move. The rotating shaft 38 drives the connecting rod 39 to move, and the connecting rod 39 drives the scraper 40 to move, so that the scraper 40 scrapes off the impurities on the filter screen 6. The scraped impurities are discharged through the discharge port 4 and then collected by the collection box 5. After the above operation is completed, the water inlet pipe 3 is connected to clean water. The clean water cleans the filter screen 6 and the residual impurities on the scraper 40, thus extending the service life of the device. At the same time, after the clean water enters the filter box 2, the float 11 drives the rack 14 to move, the rack 14 drives the gear 15 to rotate, the gear 15 drives the second drive shaft 16 to rotate, the second drive shaft 16 drives the first bevel gear 18 to rotate, the first bevel gear 18 drives the second bevel gear 19 to rotate, the second bevel gear 19 drives the third drive shaft 20 to rotate, and the third drive shaft 20... The switch plate 22 rotates, opening the connecting pipe 21 and allowing sewage to enter the sedimentation tank 27. Simultaneously, the rack 14 moves the third connecting rod 23, which in turn moves the sliding rod 24. The sliding rod 24 moves the first spring 25, which in turn moves the sliding block 26. The sliding block 26 is compressed by the first spring 25, thus fixing the sliding rod 24. The sliding rod 24, in turn, fixes the rack 14, preventing the switch plate 22 from closing and allowing sewage to be completely discharged into the sedimentation tank 27. Simultaneously, the fourth drive shaft 31 rotates the third bevel gear 41, which in turn rotates the fourth bevel gear 42, which in turn rotates the fifth drive shaft 43.The fifth drive shaft 43 drives the second sprocket 45 to rotate. The second sprocket 45 drives another second sprocket 45 to rotate via the second chain 46. The second sprocket 45 drives the sixth drive shaft 44 to rotate. The sixth drive shaft 44 drives the pinion 47 to rotate. The pinion 47 drives the large gear 48 to rotate. The large gear 48 drives the seventh drive shaft 49 to rotate. The seventh drive shaft 49 drives the half gear 50 to rotate. The half gear 50 drives the rectangular gear frame 51 to move. The rectangular gear frame 51 drives the sliding plate 52 to move. The sliding plate 52 opens the bottom of the storage tank 53, allowing the flocculant in the storage tank 53 to fall into the sedimentation tank 27. This allows for the automatic addition of flocculant after the sewage enters the sedimentation tank 27, facilitating the sedimentation of the sewage. At the same time, the rectangular gear frame 51 drives the push block 54 to move. The push block 54 pushes the locking block 28, compressing the second spring 30, causing the locking block 28 to move via the second spring 30. Afterwards, the sliding block 26 separates from the locking block 28, preventing the sliding block 26 from fixing the sliding rod 24. This causes the rack 14 to move, thereby closing the switch plate 22. If there is still a lot of sewage in the filter box 2, the switch plate 22 cannot be completely closed. If there is little or no sewage remaining in the filter box 2, the rack 14 drives the switch plate 22 to close completely. After the rectangular gear frame 51 resets, the locking block 28 is reset by the second spring 30, allowing the sliding block 26 to contact the locking block 28, thus fixing the sliding rod 24. The rectangular gear frame 51 drives the large gear 48 through the small gear 47, resulting in a lower rotation speed of the seventh transmission shaft 49 and a slower movement speed of the rectangular gear frame 51. Through the time difference between the rectangular gear frame 51 and the switch plate 22, the sewage in the filter box 2 is completely discharged into the sedimentation tank 27. After the sewage is discharged, the remaining sewage is connected to the inlet pipe 3 for the next round of sewage purification.

[0067] Example 2

[0068] The difference between this embodiment and Embodiment 1 is that a sealed door is provided on the outside of the filter box 2. When it is necessary to replace the oil adsorption layer 7, the sealed door is opened, the oil adsorption layer 7 is extracted, and then a new oil adsorption layer 7 is replaced, thereby maintaining the purification effect of the device.

[0069] Example 3

[0070] The difference between this embodiment and Embodiment 1 is that multiple ultraviolet lamps are fixedly connected to the inner wall of the top of the connecting pipe 21. By extending the connecting pipe 21, the sewage is irradiated for a long time through multiple ultraviolet lamps, thereby killing the microorganisms in the sewage.

[0071] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
