Description

Technical Field

[0001] This utility model relates to the field of pollution remediation dosing technology, and more specifically, to a dosing device for in-situ remediation of groundwater pollution. Background Technology

[0002] The in-situ remediation chemical dosing device for groundwater pollution directly administers chemicals to the contaminated area, eliminating the need to extract and treat groundwater, thus minimizing disruption to the groundwater system. The device uses injection wells to directly inject chemicals into the target area, effectively remediating pollutants and reducing treatment costs.

[0003] A search of existing publicly available technical documents reveals that Chinese Patent Publication No. CN216440484U discloses an intelligent dosing device for in-situ remediation of groundwater pollution. This device primarily uses a metering hopper to deliver chemicals to a mixing tank via a dosing funnel; the discharge port of the mixing tank is connected to a centrifugal pump via a buffer tank. This utility model provides an intelligent dosing device for in-situ remediation of groundwater pollution. Through the controllable use of the chemical addition components, solvent tank, and water storage tank, it achieves precise, unmanned operation from chemical mixing to dosing, effectively improving the treatment effect and significantly reducing maintenance costs. However, this dosing device has the following drawbacks.

[0004] While chemical dosing devices can add chemicals during in-situ remediation of groundwater pollution, the chemicals are difficult to distribute evenly during the dosing process, resulting in poor dosing uniformity and consequently, poor treatment effect. This necessitates the use of chemical dosing devices for in-situ remediation of groundwater pollution. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, this utility model provides a groundwater pollution in-situ remediation chemical dosing device.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a groundwater pollution in-situ remediation dosing device, comprising a chemical tank, a valve, and a dosing pipe. The valve is threadedly connected to the bottom end of the chemical tank, and the dosing pipe is fixedly connected to the bottom end of the valve. A dispersing dosing mechanism is provided on one side of the outer wall of the dosing pipe. The dispersing dosing mechanism includes a support bar fixedly disposed on one side of the outer wall of the dosing pipe, and a rotary motor is fixedly connected to one end of the support bar. A drive gear is fixedly connected to the outer wall of the output end of the rotary motor. A transmission gear is meshed and driven to the outer wall of the drive gear, and a rotating rod is fixedly connected to the lower surface of the transmission gear. The dispersing dosing mechanism also includes a rotating column, a lower perforated plate, and an outer ring. The rotating column is fixedly connected to the bottom end of the rotating rod, and the lower perforated plate is fixed to the bottom end of the rotating column. The outer ring is located outside the rotating column and fixed to the top end of the lower perforated plate.

[0007] Preferably, the inner wall of the transmission gear is rotatably connected to the dosing pipe, and both the support and the drive gear are made of stainless steel. Multiple blades are fixedly connected to the outer wall of the rotating column, and the multiple blades are arranged in a circular, equidistant distribution. A sleeve plate is welded to the top of the medicine tank, and a stirring rod is rotatably connected to the inner wall of the sleeve plate. A stirring motor is fixedly installed at the top of the stirring rod. A support rod is fixedly connected between the stirring motor and the sleeve plate. Limiting rings are rotatably connected to both the top and bottom of the transmission gear, and both limiting rings are fixedly connected to the dosing pipe.

[0008] According to the above technical solution, after stirring, the chemical solution is poured into the dosing pipe by opening the valve. At the same time, the dosing pipe supports the support bar, and the rotating motor causes the drive gear to rotate. The drive gear drives the transmission gear to mesh and rotate. The transmission gear rotates between two limit rings, the rotating rod causes the rotating column to rotate, and the lower perforated plate causes the outer perforated ring to rotate. In this way, the groundwater pollution in-situ remediation chemical solution can be dispersed and discharged through multiple holes on the outer perforated ring, while the bottom rotating dosing is carried out through the lower perforated plate.

[0009] Preferably, a protective assembly is provided on one side of the rotating rod; the protective assembly includes a support ring fixedly disposed on one side of the rotating rod, and the support ring is fixedly connected to the dosing tube; multiple support columns are fixedly installed at the bottom end of the support ring, and a connecting ring is provided at the bottom end of the support column, the multiple support columns are fixedly connected to the connecting ring, a guide cylinder is fixedly installed on the lower surface of the connecting ring, the inner wall of the guide cylinder is a smooth surface, and the inner diameter of the top end of the guide cylinder is smaller than the inner diameter of its bottom end.

[0010] According to the above technical solution, when the dosing pipe discharges the liquid medicine downwards, the support ring supports multiple pillars, the pillars support the connecting ring, and the guide cylinder can protect and guide the liquid medicine outside the rotating column. The liquid medicine flows along the inner wall of the guide cylinder to the outer wall of the rotating column.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] 1. This utility model adopts a dispersed dosing mechanism, with a support bar supporting a rotary motor. The rotary motor causes the drive gear to rotate, which in turn drives the transmission gear to mesh and rotate. The transmission gear rotates between two limit rings. The rotating rod causes the rotating column to rotate, and the rotating column simultaneously drives the lower row of perforated discs to rotate. The lower row of perforated discs causes the outer ring of perforated discs to rotate. The dosing can achieve large-area uniform dispersion of the dosing, making the dosing more uniform and resulting in better in-situ remediation of groundwater pollution.

[0013] 2. This utility model adopts a protective component. When the dosing pipe discharges the liquid medicine downwards, the dosing pipe supports the support ring, the support ring supports multiple pillars, the pillars support the connecting ring, and the guide cylinder can protect and guide the liquid medicine outside the rotating column, preventing it from splashing out of the outer wall of the rotating column, thus saving more liquid medicine.

[0022] In this embodiment, as shown in the appendix Figure 1-3As shown, valve 2 is threadedly connected to the bottom of medicine tank 1, and dosing pipe 3 is fixedly connected to the bottom of valve 2. A dispersing dosing mechanism is provided on one side of the outer wall of dosing pipe 3. The dispersing dosing mechanism includes a support bar 4 fixedly installed on one side of the outer wall of dosing pipe 3, and a rotary motor 5 is fixedly connected to one end of the support bar 4.

The dispersing dosing mechanism also includes a rotating column 10, a lower perforated plate 11, and an outer ring 12. The rotating column 10 is fixedly connected to the bottom of the rotating rod 9, and the lower perforated plate 11 is fixed to the bottom of the rotating column 10. The outer ring 12 is located outside the rotating column 10 and fixed to the top of the lower perforated plate 11.

[0023] In this embodiment, as shown in the appendix Figure 2-4 As shown, multiple blades 13 are fixedly connected to the outer wall of the rotating column 10.

After stirring, the solution is poured into the dosing pipe 3 by opening the valve 2, and flows down the outer wall of the rotating column 10 through the dosing pipe 3.

[0025] Simultaneously, the dosing pipe 3 supports the support bar 4, which in turn supports the rotary motor 5.
