Abstract
Description
Technical Field
[0001] This utility model relates to the field of groundwater remediation technology, specifically to a drug delivery device for groundwater remediation. Background Technology
[0002] Groundwater resources are an important component of water resources, and groundwater remediation technology is a treatment technology that involves injecting or mixing agents into the underground environment to break down and degrade pollutants in the groundwater into non-toxic or less harmful substances through chemical reactions.
[0003] Existing groundwater remediation methods typically involve extracting groundwater from a single pipe or injecting chemicals into the groundwater. These methods have several drawbacks: single-point extraction covers a small area of groundwater; increasing the pipe diameter requires drilling larger holes, but large drill bits are very expensive; and the drilling speed is slow due to the large drilling area, resulting in high costs, slow setup, and limited coverage. Utility Model Content
[0004] Therefore, the purpose of this utility model is to provide a drug delivery device for groundwater remediation, so as to solve the technical problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a groundwater remediation drug delivery device, comprising a base plate and a submersible pump. A mixing tank is connected to the top of the base plate, and a first guide plate and a second guide plate are respectively connected inside the mixing tank. A storage tank is connected to the top of the mixing tank, and a discharge valve is installed at the bottom of the storage tank. A confluence pipe is connected between the discharge valve and the mixing tank, and a pumping pipe is connected between the submersible pump and the confluence pipe. A support is passed through one side of the bottom of the base plate, and a limit plate and a distribution pipe are respectively connected to the lower part of the support. A torsion spring shaft is connected between the distribution pipe and the support, and a handle is connected to the top of the distribution pipe by a pull rope. A through hole is opened on the outer surface of the distribution pipe, and a flexible hose is connected between the distribution pipe and the mixing tank.
[0006] By adopting the above technical solution, when installing the distribution pipe, the worker first pulls the rope by the handle to rotate the distribution pipe until it is parallel to the support. Then, the worker lowers the support into the groundwater through another hole in the ground. Once the support, distribution pipe, and hose are in the groundwater area, the worker stops operating the handle to stop pulling the rope on the distribution pipe. At this point, the torsion spring shaft drives the distribution pipe to rotate perpendicular to the support, and a limiting plate restricts the distribution pipe to rotate only 90 degrees. The perpendicularity of the distribution pipe to the support ensures that the distribution pipe is parallel to the groundwater, facilitating large-scale chemical dosing. Because the handle's shape limits the rope's position, it prevents the rope from being completely pulled underground when the distribution pipe reverses and pulls the rope. Furthermore, since the rope is a plastic-coated steel wire rope with a surface made of polyethylene... The cable is wrapped in rubber and plastic materials such as urethane to prevent the internal steel wires from rusting due to contact with water, thus increasing the service life of the rope. After the device is ready, the staff turns on the submersible pump and the discharge valve. The submersible pump draws some groundwater into the confluence pipe, while the discharge valve sends the repair powder from the storage tank into the confluence pipe. The water and repair powder are initially mixed into a liquid in the confluence pipe before entering the mixing tank. Then, the liquid is continuously divided and collided by multiple staggered first and second guide plates in the mixing tank for secondary mixing, so that the repair powder is fully dissolved in the water. After that, the liquid enters the distribution pipe through the hose and flows out into the groundwater through the through hole, thereby repairing the groundwater. The staff can also add a water pump between the hose and the mixing tank to improve the stability of the fluid flow in the device.
[0007] Furthermore, the distribution pipe is rotatably connected to the support.
[0008] By adopting the above technical solution, the staff pulls the rope to pull the distribution pipe, causing the distribution pipe to rotate to a state parallel to the support. Then, the staff sends the support into the groundwater through another hole in the ground.
[0009] Furthermore, the distribution tube abuts against the limiting plate.
[0010] By adopting the above technical solution, the distribution tube is driven to rotate perpendicular to the support by the torsion spring shaft, and the distribution tube is limited to rotating only 90 degrees by the limiting plate.
[0011] Furthermore, the through holes are provided in multiple groups, which are arranged in a ring array.
[0012] By adopting the above technical solution, the liquid medicine enters the distribution pipe through the hose and then flows out through the through hole into the groundwater, thereby repairing the groundwater.
[0013] Furthermore, the pull rope is a plastic-coated steel wire rope.
[0014] By adopting the above technical solution, since the pull rope is a plastic-coated steel wire rope with its surface wrapped in polyurethane and other rubber and plastic materials, the internal steel wires are prevented from rusting due to contact with water, thereby increasing the service life of the pull rope.
[0015] Furthermore, the handle has an "I" shaped cross-section and abuts against the bracket.
[0016] By adopting the above technical solution, the shape of the handle limits the pull rope, thus preventing the pull rope from being completely pulled underground when the distribution pipe reverses and pulls the pull rope.
[0017] Furthermore, multiple first guide vanes and multiple second guide vanes are provided, and the multiple first guide vanes and multiple second guide vanes are distributed alternately.
[0018] By adopting the above technical solution, the medicine liquid is continuously divided and collided for secondary mixing through multiple staggered first and second guide plates in the mixing box, so that the repair powder is fully dissolved in the water.
[0019] Furthermore, a sealing cover is connected to the top of the storage box, and the sealing cover is detachably connected to the storage box.
[0020] By adopting the above technical solution, the staff removes the sealing cap and pours the repair powder into the storage box. Afterwards, the staff puts the sealing cap back to prevent the powder from being contaminated.
[0021] Furthermore, the outer surface of the storage bin is provided with a viewing window, and the viewing window is made of acrylic material.
[0022] By adopting the above technical solution, when delivering medicine to groundwater, staff can check the remaining amount of repair powder in the storage box through a window so that they can add the powder in a timely manner.
[0023] In summary, the present invention has the following main advantages:
[0024] 1. This utility model, through the arrangement of a bracket, a limiting plate, a distribution pipe, a through hole, a torsion spring shaft, a pull rope, and a hose, allows the distribution pipe to be pulled by pulling the rope with a handle, causing the distribution pipe to rotate to a state parallel to the bracket. After the bracket, distribution pipe, and hose are delivered into the groundwater area, the handle is stopped, and the pull rope no longer pulls on the distribution pipe. At this time, the torsion spring shaft drives the distribution pipe to rotate perpendicular to the bracket, and the limiting plate limits the distribution pipe to a rotation of only 90 degrees. The perpendicularity of the distribution pipe to the bracket makes the distribution pipe parallel to the groundwater body, thus facilitating large-scale chemical dosing; it can deliver chemicals to a large area of groundwater without the need to open large holes, thus facilitating the remediation of large groundwater bodies. The structure is simple, the cost is low, and the operation is convenient.
[0025] 2. This utility model, through the arrangement of a mixing tank, a submersible pump, a confluence pipe, a first guide plate, and a second guide plate, allows the submersible pump to draw some groundwater into the confluence pipe. Simultaneously, the discharge valve sends the repair powder from the storage tank into the confluence pipe. The water and repair powder are initially mixed into a liquid in the confluence pipe before entering the mixing tank. Subsequently, the liquid is further mixed by the multiple staggered first and second guide plates within the mixing tank, which continuously divide and collide the liquid, ensuring that the repair powder is fully dissolved in the water. The liquid then flows through a hose into a distribution pipe and out through a through-hole into the groundwater, thereby repairing the groundwater. By mixing and dissolving the powder with water before sending it underground, the phenomenon of the powder becoming damp and clumping, clogging the hose, distribution pipe, or through-hole, and becoming difficult to clear, is avoided.

Detailed Implementation
[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.
[0034] The embodiments of this utility model will be described below based on its overall structure.
[0035] Example 1:
[0036] Groundwater remediation chemical delivery devices, such as Figure 1 , Figure 2 and Figure 6 As shown, the system includes a base plate 1 and a submersible pump 6. A mixing tank 2 is connected to the top of the base plate 1. A first guide plate 18 and a second guide plate 19 are connected inside the mixing tank 2. Multiple first guide plates 18 and multiple second guide plates 19 are provided. The multiple first guide plates 18 and multiple second guide plates 19 are staggered. Through the multiple staggered first guide plates 18 and second guide plates 19 in the mixing tank 2, the medicine liquid is continuously divided and collided for secondary mixing, so that the repair powder is fully dissolved in the water. A storage tank 3 is connected to the top of the mixing tank 2. A discharge valve 9 is installed at the bottom of the storage tank 3. A confluence pipe 8 is connected between the discharge valve 9 and the mixing tank 2. A water pumping pipe 7 is connected between the submersible pump 6 and the confluence pipe 8. The submersible pump 6 pumps some groundwater into the confluence pipe 8. At the same time, the discharge valve 9 sends the repair powder in the storage tank 3 into the confluence pipe 8. The water and the repair powder are initially mixed into a medicine liquid in the confluence pipe 8 before entering the mixing tank 2.
[0037] See Figures 1-5In the above embodiment, a bracket 10 extends through one side of the bottom of the base plate 1. A distribution pipe 12 is rotatably connected to the bracket 10, and the distribution pipe 12 abuts against the limiting plate 11. The limiting plate 11 and the distribution pipe 12 are respectively connected to the lower part of the bracket 10. A torsion spring shaft 14 connects the distribution pipe 12 and the bracket 10. A handle 16 is connected to the top of the distribution pipe 12 via a pull rope 15. The pull rope 15 is a plastic-coated steel wire rope, and the handle 16 has an "I" shaped cross section. The handle 16 abuts against the bracket 10. The worker first pulls the pull rope 15 through the handle 16 to pull the distribution pipe 12, causing the distribution pipe 12 to rotate to a state parallel to the bracket 10. Then, the worker sends the bracket 10 into the groundwater through another hole on the ground. After the bracket 10, the distribution pipe 12, and the hose 17 are sent into the groundwater area, the worker stops operating the handle 16 so that the pull rope 15 no longer pulls the distribution pipe 12. At this time, the distribution pipe 12 is driven to rotate perpendicular to the bracket 10 by the torsion spring shaft 14, and the limiting plate 11 is connected to the distribution pipe 12. The distribution pipe 12 is limited to a 90-degree rotation. The distribution pipe 12 is perpendicular to the support 10, making the water level of the distribution pipe 12 parallel to the groundwater, thus facilitating large-scale chemical dosing. The shape of the handle 16 limits the pull rope 15, preventing the pull rope 15 from being completely pulled underground when the distribution pipe 12 reverses and pulls it. The pull rope 15 is a plastic-coated steel wire rope with a surface wrapped in polyurethane and other rubber and plastic materials, preventing the internal steel wire from rusting when in contact with water, thus increasing the service life of the pull rope 15. The outer surface of the distribution pipe 12 has through holes 13, which are arranged in four groups in a ring array. A hose 17 connects the distribution pipe 12 and the mixing tank 2. The chemical solution enters the distribution pipe 12 through the hose 17 and then flows out through the through holes 13 into the groundwater, thereby repairing the groundwater. The operator can also add a water pump between the hose 17 and the mixing tank 2 to improve the stability of the fluid flow in the device.
[0038] Example 2:
[0039] Based on the above embodiment one, the following settings are now adopted to facilitate the storage of the medicine powder.
[0040] See Figure 1 and Figure 2 In the above embodiment, a sealing cover 5 is connected to the top of the storage box 3. The sealing cover 5 is detachably connected to the storage box 3. The staff removes the sealing cover 5 and pours the repair powder into the storage box 3. After that, the staff puts the sealing cover 5 back to avoid contamination of the powder. A viewing window 4 is provided on the outer surface of the storage box 3. The viewing window 4 is made of acrylic material. The staff can check the remaining amount of repair powder in the storage box 3 through the viewing window 4 so as to add powder in time.
[0041] The implementation principle of this utility model is as follows: First, the workers drill two holes in the ground to connect to the groundwater. Then, the workers place the base plate 1 on the ground. The workers remove the sealing cover 5 and pour the repair powder into the storage box 3. Then, the workers put the sealing cover 5 back to avoid contamination of the powder. The workers can then check the remaining amount of repair powder in the storage box 3 through the viewing window 4 to add powder in time. The workers send the submersible pump 6 and the water pumping pipe 7 into the groundwater through one of the holes in the ground. Then, the workers connect the merging pipe 8 to the unloading valve 9, the mixing box 2, and the water pumping pipe 7. Finally, the workers connect the hose 17 to the mixing box 2 and the distribution pipe 12 respectively.
[0042] When installing the distribution pipe 12, the worker first pulls the pull rope 15 by the handle 16 to pull the distribution pipe 12, causing it to rotate to a position parallel to the support 10. Then, the worker lowers the support 10 into the groundwater through another hole in the ground. After the support 10, distribution pipe 12, and hose 17 are in the groundwater area, the worker stops operating the handle 16, so the pull rope 15 no longer pulls on the distribution pipe 12. At this point, the torsion spring shaft 14 drives the distribution pipe 12 to rotate perpendicular to the support 10, and a limit switch is applied. Plate 11 limits the distribution pipe 12, thus restricting the distribution pipe 12 to rotate only 90 degrees. The distribution pipe 12 is perpendicular to the support 10, making the water body of the distribution pipe 12 parallel to the groundwater, which facilitates large-scale chemical dosing. Since the shape of handle 16 limits the pull rope 15, it prevents the pull rope 15 from being completely pulled underground when the distribution pipe 12 reverses and pulls the pull rope 15. Furthermore, since the pull rope 15 is a plastic-coated steel wire rope with the surface wrapped with polyurethane and other rubber and plastic materials, it prevents the internal steel wire from contacting water and causing corrosion, thereby increasing the service life of the pull rope 15.
[0043] After the equipment is ready, the staff turns on the submersible pump 6 and the discharge valve 9. The submersible pump 6 pumps some groundwater into the confluence pipe 8, while the discharge valve 9 sends the repair powder from the storage tank 3 into the confluence pipe 8. The water and the repair powder are initially mixed into a liquid in the confluence pipe 8 and then enter the mixing tank 2. Afterwards, the liquid is continuously divided and collided by multiple staggered first guide plates 18 and second guide plates 19 in the mixing tank 2 for secondary mixing, so that the repair powder is fully dissolved in the water. Then the liquid enters the distribution pipe 12 through the hose 17 and flows out into the groundwater through the through hole 13, thereby repairing the groundwater. The staff can also add a water pump between the hose 17 and the mixing tank 2 to improve the stability of the fluid flow in the equipment.
