Abstract
Description
Technical Field
[0001] This utility model relates to the field of groundwater drug delivery technology, and in particular to a drug delivery device for groundwater remediation and treatment. Background Technology
[0002] Groundwater remediation is a key step in treating contaminated groundwater resources, aiming to reduce or eliminate the threat of pollutants to the environment and human health. Chemical injection is a common groundwater remediation technique that involves injecting specific chemicals into groundwater to degrade, adsorb, or fix pollutants.
[0003] The existing announcement number CN218507574U, entitled "Injection Device for Groundwater Remediation Agent," includes a support plate with a drilling mechanism. The drilling mechanism includes a bidirectional motor fixedly mounted at the bottom of the support plate, with a rotating shaft fixedly mounted at the motor's output end. The rotating shaft passes through the support plate, and its outer wall is rotatably connected to the support plate via bearings. A gear roller is fixedly sleeved on the outer wall of the rotating shaft. A support rod is fixedly mounted at the top of the support plate, and a fixing plate is fixedly mounted at the top of the support rod. A threaded screw is threaded into a threaded hole in the fixing plate. By setting up the drilling mechanism, the injection tube can rotate downwards, driving the drill bit to rotate, increasing the friction between the drill bit and the ground, making it easier for the injection tube to penetrate underground. This avoids encountering hard geological conditions that prevent deep injection, reducing the limitations of the device's use.
[0004] However, in the aforementioned groundwater remediation, the method involves vertically installing injection pipes on the ground. By inserting these pipes into the soil, remediation agents are delivered to the soil to treat the groundwater. However, when the agents are injected into the soil, the lack of a structure that continuously compresses and discharges the agents results in insufficient pressure during discharge. Consequently, the dispersion range of the injected agents in the soil is limited, which is not conducive to the continuous injection of agents for large-scale groundwater remediation. Utility Model Content
[0005] This invention solves the problems in related technologies and proposes a reagent delivery device for groundwater remediation and treatment.
[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: a groundwater remediation and treatment agent delivery device, including a support, a filling cylinder, and a delivery component. The support includes a bracket, with multiple anchor rods vertically fixed on the bottom surface of the bracket, which are used to fix the bracket on the bottom surface. A perforated plate is horizontally fixed on the top surface of the bracket, and a filling cylinder is vertically fixed on one vertical end face of the bracket. The top surface of the filling cylinder is open, and a filling screw is fixedly connected to the bottom end of the filling cylinder. The delivery component is assembled in communication with the filling screw. The top surface of the filling cylinder is open, and a piston is inserted inside the filling cylinder. A piston rod is vertically fixed on the top surface of the piston.
[0007] As a preferred embodiment, the dispensing component includes a dispensing tube, with a spiral tube vertically connected and fixed at the liquid inlet port of the dispensing tube, and the spiral tube being threadedly assembled in the filling screw cylinder.
[0008] As a preferred embodiment, multiple spiral rings are uniformly and vertically connected and fixed on the bottom surface of the delivery tube, and a lower insertion tube column is vertically arranged below the multiple spiral rings.
[0009] As a preferred option, the top of the lower insertion tube is vertically connected and fixed with a screw shell, and the screw shell is threadedly assembled and connected with a screw ring.
[0010] As a preferred option, the bottom of the outer circumference of the lower insertion column is provided with multiple liquid outlets.
[0011] As a preferred embodiment, a screw hole plate is horizontally fixed to the top of the piston rod, and a guide rod is vertically fixed to the bottom surface of the screw hole plate, with the guide rod slidingly inserted into the hole plate.
[0012] As a preferred embodiment, a motor is vertically fixed on the bottom surface of the orifice plate, and a screw is vertically rotatably connected to the top surface of the orifice plate, with the bottom end of the screw fixed to the output end of the motor, and the screw thread passing through the orifice plate.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: During use, the dispensing component is assembled on the bottom surface of the injection cylinder. Then, the piston inside the injection cylinder pulls the piston rod out, and the remediation solution is injected into the injection cylinder. Then, the piston pulls the piston rod into the injection cylinder, pushing the piston rod to slide inside the injection cylinder, pressurizing the remediation solution and driving it into the dispensing component. The solution is then injected into the soil to remediate groundwater. During injection, the pressurized remediation solution expands over a larger area, ensuring the scalability of groundwater remediation. Simultaneously, when the remediation solution is injected, the motor drives the screw to rotate, and the screw thread drives the screw plate at the top of the piston rod to move downward under the guide rod, pushing the piston to push the pressurized remediation solution out. The pressure drives the agent to be discharged, and the dispersion range in the soil expands, which is conducive to the continuous injection of agents for large-scale soil and groundwater remediation.

[0026] like Figures 1 to 5 As shown, a groundwater remediation agent dispensing device includes a support 1, a dispensing cylinder 2, and a dispensing component 3. The support 1 includes a bracket 11, with multiple anchor rods 12 vertically fixed to the bottom surface of the bracket 11 for fixing the bracket 11 to the bottom surface. A perforated plate 13 is horizontally fixed to the top surface of the bracket 11, and a dispensing cylinder 2 is vertically fixed to one vertical end face of the bracket 11. The top surface of the dispensing cylinder 2 is open, and the bottom end of the dispensing cylinder 2 is connected to and fixed with a dispensing screw cylinder 21. The filling component 3 is assembled in connection with the filling cylinder 21. The top surface of the filling cylinder 2 is open, and a piston 22 is inserted inside the filling cylinder 2. A piston rod 23 is vertically fixed on the top surface of the piston 22. A screw hole plate 24 is horizontally fixed at the top of the piston rod 23, and a guide rod 25 is vertically fixed on the bottom surface of the screw hole plate 24. The guide rod 25 is slidably inserted into the hole plate 13. A motor 14 is vertically fixed on the bottom surface of the hole plate 13, and a screw 15 is vertically rotatably connected to the top surface of the hole plate 13. The screw 15 is threaded through and assembled in the screw hole plate 24. During use, the dispensing component 3 is connected and assembled on the bottom surface of the filling cylinder 2. Then, the piston 22 inside the filling cylinder 2 pulls the piston rod 23 out, and the repair solution is injected into the filling cylinder 2. Then, the piston 22 pulls the piston rod 23 into the filling cylinder 2, and pushes the piston rod 23 to slide inside the filling cylinder 2, pressurizing the repair solution and driving it into the dispensing component 3. It is then injected into the soil to repair groundwater. During injection, the pressurized repair solution expands to a larger area, ensuring the scalability of groundwater repair. At the same time, when the repair solution is injected, the motor 14 is started to drive the screw 15 to rotate. The screw hole plate 24 at the top of the piston rod 23 moves down under the guidance of the guide rod 25, pushing the piston 22 to push the pressurized repair solution to be discharged. The pressure drives the agent to be discharged, and the dispersion range in the soil expands, which is conducive to the continuous injection of agents to repair groundwater over a large area.
[0027] In one embodiment, such as Figure 2 and 5As shown, the dispensing component 3 includes a dispensing pipe 31. A screw tube 32 is vertically connected and fixed at the inlet port of the dispensing pipe 31, and the screw tube 32 is threadedly assembled in the filling screw cylinder 21. Multiple screw rings 33 are uniformly vertically connected and fixed on the bottom surface of the dispensing pipe 31, and a lower insertion pipe column 34 is vertically arranged below the multiple screw rings 33. A screw shell 35 is vertically connected and fixed at the top of the lower insertion pipe column 34, and the screw shell 35 is threadedly assembled with the screw rings 33. Multiple outlets 36 are opened through the bottom of the outer circumference of the lower insertion pipe column 34. In use, the screw tube 32 at the top of the dispensing pipe 31 is threadedly assembled in the filling screw cylinder 21 on the bottom surface of the filling cylinder 2. Then, the screw rings 33 at the bottom of the dispensing pipe 31 are threadedly connected to the lower insertion pipe column 34. The lower insertion pipe column 34 is inserted into the soil, and the remediation liquid is discharged into the soil through the outlets 36 at the bottom of the lower insertion pipe column 34 inserted into the soil to remediate the groundwater at the bottom of the soil.
[0028] In this embodiment, during use, the top screw tube 32 of the dispensing tube 31 of the dispensing component 3 is threadedly connected to the dispensing screw tube 21 on the bottom surface of the dispensing cylinder 2. Then, the bottom screw ring 33 of the dispensing tube 31 is threadedly connected to the lower insertion tube 34. The lower insertion tube 34 is inserted into the soil, and the repair fluid is discharged into the soil through the outlet 36 at the bottom of the lower insertion tube 34 inserted into the soil to repair the groundwater at the bottom of the soil. The dispensing component 3 is connected to the bottom surface of the dispensing cylinder 2. Then, the piston 22 inside the dispensing cylinder 2 pulls the piston rod 23 out to inject the repair solution into the dispensing cylinder 2. When the piston 22 pulls the piston rod 23 into the dispensing cylinder 2, the piston rod 23 is pushed to slide inside the dispensing cylinder 2. At the same time, when the repair solution is dispensed, the motor 14 is started to drive the screw 15 to rotate. The screw drive plate 24 at the top of the piston rod 23 moves down under the guidance of the guide rod 25, pushing the piston 22 to push the pressurized repair solution to be dispensed.
[0029] The above are preferred embodiments of the present utility model. Those skilled in the art can make changes and modifications to the above embodiments. Therefore, the present 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 the present utility model shall fall within the protection scope of the present utility model.
