Description

Technical Field

[0001] This utility model relates to the technical field of groundwater remediation devices, and in particular to a groundwater remediation device for a stratified extraction well. Background Technology

[0002] Layered extraction wells are an advanced technology in groundwater remediation, mainly used to accurately identify, monitor and treat contaminated groundwater aquifers. A layered extraction well refers to a well in which multiple independent filtration sections are set in a borehole, and aquifers at different depths are hydraulically isolated by isolation devices such as expansion packers and stop plugs, so that the contaminated water layers can be extracted and remediated later.

[0003] In groundwater remediation, extraction wells are a common technique used to extract contaminated groundwater for treatment. However, in practice, directly pumping water from a specific aquifer can lead to the simultaneous extraction of water from different depths. This not only increases the complexity of subsequent water treatment but also reduces the effectiveness of the remediation. Because existing pumping pipes are not designed for sealing, they can only extract water from a single layer when inserted into the extraction well, failing to effectively isolate layers at different depths, making it impossible to accurately extract water from the desired layer. This problem is particularly prominent in practical applications, resulting in resource waste, increased energy consumption, and negative environmental impacts.

[0004] However, while existing extraction well technologies can generally extract groundwater, they have significant limitations when extracting specific aquifers. Especially in environments requiring precise control of the target aquifer, current technologies cannot effectively prevent mixing between different aquifers, thus affecting remediation effectiveness and efficiency. Therefore, there is an urgent need for an improved technology that can effectively isolate aquifers at different depths, ensuring the precise extraction of water from a specific aquifer. Utility Model Content

[0005] This invention solves the problems in related technologies and proposes a groundwater remediation device for stratified extraction wells.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: a groundwater remediation device for a stratified extraction well, comprising a water intake component and a remediation component. The water intake component includes a lower ring plate, an upper ring plate, and a gas distribution cylinder. The lower ring plate and the upper ring plate are horizontally arranged along the vertical direction, and the upper ring plate is arranged above the lower ring plate. Grooves are formed on the outer circumference of both the lower and upper ring plates, and airbag rings are embedded in the grooves of both the lower and upper ring plates. A gas distribution cylinder is vertically inserted through the center of the upper ring plate, and the outer wall of the gas distribution cylinder is fixed to the inner wall of the lower ring plate and the upper ring plate. The outer wall of the gas distribution cylinder is connected and fixed to the airbag ring. The repair components include a water suction cylinder and a water return cylinder. The water suction cylinder and the water return cylinder are set between the lower ring plate and the upper ring plate. The water suction cylinder and the water return cylinder are sleeved on the outside of the gas distribution cylinder in a vertical direction. A water return cylinder is set above the water suction cylinder. The inner walls of the water suction cylinder and the water return cylinder are fixed to the outer wall of the gas distribution cylinder.

[0007] As a preferred embodiment, a through-tube is vertically connected and fixed to the return water hole cylinder and the upper ring plate on the pumping hole cylinder, and a pumping hose is connected and fixed to the top of the through-tube.

[0008] As a preferred embodiment, a pumping rod is vertically connected and fixed to the top of the pumping hose, and a pumping pump is connected and fixed to the pumping rod. A repair cylinder is vertically connected and fixed to the top of the pumping rod, and a chemical dosing port is vertically connected and fixed to the top of the repair cylinder.

[0009] As a preferred embodiment, a return water hose is vertically connected and fixed on the top surface of the return water cylinder, and a return water rod cylinder is vertically connected and fixed at the top end of the return water hose.

[0010] As a preferred embodiment, the top end of the return water rod is connected and fixed to the bottom surface of the repair cylinder, and a return water pump is connected and fixed to the return water rod.

[0011] As a preferred embodiment, a lifting air rod is vertically connected and fixed on the top surface of the air distribution cylinder, and an air pump is connected and fixed on the lifting air rod.

[0012] As a preferred option, a sealing ring gasket is fixed on the outer circumferential surface of the airbag ring.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: the lower ring plate and the upper ring plate are horizontally arranged in the vertical direction to form a double-layer structure for filtration and lifting, which enhances the ability to capture and remove polluted water. The airbag ring is embedded in the groove and is inflated by an air pump, which causes the airbag ring to undergo a certain elastic deformation. The airbag ring expands as it is inflated, and the expanded airbag ring drives the sealing ring gasket to seal against the inner wall of the layered extraction well. Thus, by using the lower ring plate and the upper ring plate to be horizontally arranged in the vertical direction, a water layer sealed extraction space is set up, forming a double-layer structure for filtration and lifting, which enhances the ability to capture and remove polluted water and improves the sealing performance.

[0022] like Figures 1 to 5 As shown, a groundwater remediation device for a stratified extraction well includes a water intake component 1 and a remediation component 2. The water intake component 1 includes a lower ring plate 11, an upper ring plate 12, and a gas distribution cylinder 15. The lower ring plate 11 and the upper ring plate 12 are horizontally arranged in the vertical direction, and the upper ring plate 12 is arranged above the lower ring plate 11. Grooves 13 are formed on the outer circumference of both the lower ring plate 11 and the upper ring plate 12, and airbag rings 14 are embedded in the grooves 13 of both the lower ring plate 11 and the upper ring plate 12. The gas distribution cylinder 15 is vertically inserted through the center of the lower ring plate 11 and the upper ring plate 12, and the outer wall of the gas distribution cylinder 15 is fixed to the inner wall of the lower ring plate 11 and the upper ring plate 12, and the outer wall of the gas distribution cylinder 15 is connected to the airbag ring 14. The fixing and repair component 2 includes a pumping nozzle 21 and a return nozzle 27, which are positioned between the lower ring plate 11 and the upper ring plate 12. The pumping nozzle 21 and the return nozzle 27 are vertically fitted around the outside of the gas distribution cylinder 15, with the return nozzle 27 positioned above the pumping nozzle 21. The inner walls of the pumping nozzle 21 and the return nozzle 27 are fixed to the outer wall of the gas distribution cylinder 15. A lifting air rod 16 is vertically connected and fixed to the top surface of the gas distribution cylinder 15, and an air pump 17 is connected and fixed to the lifting air rod 16. A sealing ring gasket 18 is fixed to the outer circumference of the airbag ring 14. The groundwater remediation device achieves effective groundwater remediation through the synergistic action of its components. The lower ring plate 11 and the upper ring plate 12 are horizontally arranged along the vertical direction, forming a double-layer structure for filtration and lifting, enhancing the ability to capture and remove contaminated water. An airbag ring 14 is embedded in a groove 13. The airbag ring 14 is inflated by an air pump 17, causing it to undergo elastic deformation. This adjusts the pressure between the airbag ring 14 and the lower ring plate 11 and upper ring plate 12, helping to stabilize and adjust the sealing performance of the repair system. A gas distribution cylinder 15 passes through the upper and lower ring plates and connects to the airbag ring, ensuring smooth gas flow. A water extraction port 21 and a water return port 27 are positioned between the upper and lower ring plates for extracting and reinjecting the treated water. These ports are fitted onto the outer wall of the gas distribution cylinder 15, increasing the vertical exchange channels for water and improving the repair effect. A lifting air rod 16 is vertically connected and fixed to the top surface of the gas distribution cylinder 15 and connected to the air pump 17, facilitating operation of the device and maintaining a stable gas supply. The overall working principle is as follows: the air pump 17 supplies air to the airbag ring 14 to generate a certain pressure, and the lifting air rod 16 and the air distribution cylinder 15 work together to help the sinking water extraction cylinder 21 to extract groundwater; the air distribution cylinder 15 allows air to circulate and maintain a sealed environment, and nitrogen will cause the airbag ring to change and change the sealing performance between it and the ring plate. At the same time, the water will be reinjected through the return water cylinder 27, and multiple cycles and treatments will be carried out until the groundwater quality meets the remediation requirements.

[0023] In one embodiment, such as Figure 2 and 4As shown, a through-tube 22 is vertically connected and fixed to the return water tube 27 and the upper ring plate 12 on the pumping tube 21. A pumping hose 23 is fixedly connected to the top of the through-tube 22. A pumping rod tube 24 is vertically connected and fixed to the top of the pumping hose 23. A pumping pump 25 is fixedly connected to the pumping rod tube 24. A repair tube 26 is vertically connected and fixed to the top of the pumping rod tube 24. A chemical dosing port 261 is vertically connected and fixed to the top of the repair tube 26. This system is used for underwater water sampling. A return water orifice 27 and an upper ring plate 12 fix a perforating cylinder 22. The perforating cylinder 22 and a suction hose 23 form a pumping channel. The suction hose 23 leads water to the upper part of the pumping rod cylinder 24. A pumping pump 25 is installed in the pumping rod cylinder 24 to extract the water sample. A repair cylinder 26 is fixed to the top of the pumping rod cylinder 24. The top of the repair cylinder 26 has a chemical dosing port 261 for adding chemical agents during water sampling for water remediation or testing. The working principle is as follows: First, an underwater sample is extracted through the pumping orifice 21. The sample flows into the suction hose 23 through the return water orifice 27 and the perforating cylinder 22, and is then pressurized by the pumping pump 25 and extracted, flowing out through the top of the pumping rod cylinder 24. The extracted water sample is in the repair cylinder 26, where necessary chemical agents can be added through the chemical dosing port 261 for further treatment or testing, achieving the purpose of water remediation or water quality testing.

[0024] In one embodiment, such as Figure 4 and 5 As shown, a return water hose 28 is vertically connected and fixed to the top surface of the return water orifice 27, and a return water rod 29 is vertically connected and fixed to the top end of the return water hose 28. The top end of the return water rod 29 is connected and fixed to the bottom surface of the repair cylinder 26, and a return water pump 291 is connected and fixed to the return water rod 29. The return water orifice 27 is used to collect and guide the return water into the system. The return water hose 28 is responsible for transporting the water flow in the return water orifice 27 to the return water rod 29. The return water rod 29 serves as a channel for water flow, and the return water pump 291 connected to its top end is used to draw and increase the water flow rate to ensure that the water can smoothly return to the repair cylinder 26. The entire system collects return water through the return water inlet 27, transmits it through the return water hose 28, and then the return water rod 29 and the return water pump 291 work together to continuously return the water to the repair cylinder 26, thereby realizing the recycling of water within the system, reducing dependence on external water sources, maintaining the water quality balance within the system, and improving repair efficiency.

[0025] The working principle of this embodiment: First, when extracting and repairing water in the stratified extraction well, the water intake component 1 is inserted into the stratified extraction well. After reaching the appropriate depth for extracting water, the air pump 17 on the lifting air rod 16 is started to drive external air into the air distribution cylinder 15. The air is guided into the airbag ring 14 of the lower ring plate 11 and the upper ring plate 12. The airbag ring 14 is inflated and expands. The expanded airbag ring 14 drives the sealing ring gasket 18 to seal the inner wall of the stratified extraction well. Then, the pump 25 on the pumping rod cylinder 24 in the repair component 2 is started to drive the stratified well water in the stratified extraction well into the pumping hole cylinder 21. Then the well water is guided through the pumping hose 23 into the pumping rod cylinder 24, and then the well water is guided into the repair cylinder 26. Repair agent is added to the repair cylinder 26. Then the pumping pump 25 is turned off and the return pump 291 on the return rod cylinder 29 is turned on to drive the repaired water in the repair cylinder 26 through the return hose 28 into the return hole cylinder 27. Then the repaired water will flow back into the stratified well water in the stratified extraction well.

[0026] The above are preferred embodiments of this utility model. Those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments described above. Any obvious improvements, substitutions or modifications made by those skilled in the art based on this utility model shall fall within the protection scope of this utility model.
