Description

Technical Field

[0001] This invention relates to the field of permeable reactive wall testing technology, specifically a permeable reactive wall testing device filled with a novel material, PRB. Background Technology

[0002] A reactive permeable wall is a passive in-situ groundwater treatment technology using a filling medium. The reactive wall is installed across the cross-section of the contaminated groundwater flow path. Through contact between the reactive material filling the wall and the groundwater, it degrades and retains pollutants in the water, thus achieving the purpose of remediating the contaminated groundwater.

[0003] Existing permeable reactive wall testing devices use a single method to simulate groundwater, relying on a pneumatic pump to pressurize the water and simulate its pressure. However, the airflow from the pneumatic pump can easily enter the pores of the permeable reactive wall, leading to uneven pressure distribution and affecting the accuracy of the simulation. Furthermore, existing testing devices do not allow for quick replacement of the permeable reactive wall material for comparative testing, which affects testing efficiency. Moreover, the sealing effect is poor after replacement, resulting in pressure leakage.

[0004] To address the above problems, this invention provides a testing device for a permeable reactive wall filled with a novel material, PRB, to solve these issues. Summary of the Invention

[0006] Preferably, the conversion assembly includes: a connecting column fixed to the driving column, with multiple swirl vanes fixed to its outer circumference; a sliding ring with multiple swirl vanes coaxially arranged on the connecting column; a limiting ring fixed to the side of the sliding ring away from the driving column, with multiple arc-shaped limiting grooves formed on the circumference of the limiting ring; multiple conversion plates configured and slidably disposed on the limiting grooves by means of a sliding shaft, corresponding one-to-one with the multiple limiting grooves; and a rotating ring rotatably disposed on the side of the multiple conversion plates away from the limiting ring, and slidably connected to the multiple conversion plates.

[0007] Preferably, two sliding columns are symmetrically arranged on the side wall of the rotating ring. Both sliding columns are slidably connected to the rotating ring and a pressing spring is provided between them. A guide block is rotatably arranged on the sliding column. The guide block is slidably connected to the conversion groove and is elliptical in shape.

[0008] Preferably, the conversion groove includes a sliding groove one and a sliding groove two, and the sliding groove one and the sliding groove two are disposed away from the water inlet and the sewage outlet. Each of the sliding groove one and the sliding groove two has a stepped groove at the end away from the drive column. The end of the sliding groove one away from the drive column has a drive groove one, which is a spiral groove, and the other end of the drive groove one is connected to the end of the stepped groove on the sliding groove two away from the drive column. The end of the sliding groove two away from the drive column has a drive groove two, which is a spiral groove, and its spiral direction is opposite to that of the drive groove one. The other end of the drive groove two is connected to the end of the stepped groove on the sliding groove one away from the drive column.

[0009] Preferably, the clamping assembly includes: a sliding seat slidably disposed on the drainage chamber and driven by the adjusting motor; a mounting seat fixed on the sliding seat; a fixing ring fixed on the drainage chamber; a plurality of reset posts configured, circumferentially fixed on the fixing ring and slidably connected to the sliding seat and the mounting seat, and each reset post is sleeved with a reset spring; a snap-fit ​​groove formed on the side of the sliding seat and the mounting seat away from the fixing ring; and a test assembly snapped into the snap-fit ​​groove.

[0010] Preferably, the test assembly includes: a test chamber with a retaining plate fixed to its outer wall, the retaining plate being engaged in a retaining groove; and a permeation reaction wall fixed inside the test chamber.

[0011] Preferably, the permeation reaction wall is columnar and uses a combination of multiple different materials. A sealing component is provided at one end of the test chamber near the drainage chamber, and the sealing component is slidably disposed inside the drainage chamber.

[0012] Preferably, the sealing assembly includes: a sealing ring slidably disposed within the drainage chamber, with a plurality of pressing posts fixed at the end away from the test chamber, the pressing posts being slidably disposed within the drainage chamber, and a pressing spring sleeved on the outer wall of the pressing posts; a first sealing ring, at least three in number, installed on the outer wall of the sealing ring; and a second sealing ring installed at the end of the sealing ring near the test chamber.

[0013] Compared with the prior art, the present invention provides a test device for a permeable reactive wall filled with a novel material, PRB, which has the following beneficial effects: The present invention can regulate the state of sewage entering the regulating chamber through a conversion component. When a static groundwater simulation test is required, the conversion component is brought close to the connecting cylinder, so that the inlet directly sends the groundwater sewage between the conversion component and the test component. Then, the conversion component is pushed close to the test component by the drive column to adjust the water pressure. After reaching the set value, the drive column is slowly pushed so that the amount of sewage reduced by passing through the test component is consistent with the rate at which the conversion component approaches the test component, thereby ensuring stable water pressure and improving simulation accuracy until the collection chamber has completed collection.

[0014] When simulating groundwater flow, there are two testing methods. The first method involves testing only the decontamination capacity of the permeable reactive barrier. In this method, a filter disc is installed to filter sediment from the groundwater. A drive column pushes the conversion component closer to the test component, which then opens through the conversion slot. Water is then introduced through the inlet, placing the wastewater between the connecting cylinder and the conversion component. The drive column then pulls the conversion component closer to the connecting cylinder at the same speed as the groundwater flow, thus completing the test of the permeable reactive barrier's decontamination capacity. The second method involves determining the overall decontamination capacity of the permeable reactive barrier for groundwater. The process remains the same, but the filter disc is removed before the test, allowing sediment and wastewater to flow together. A vortex vane mixes the sediment and wastewater to prevent sediment from falling to the bottom of the regulating chamber due to gravity, which would affect the test results. This accurately simulates the actual groundwater flow. Attached Figure Description

Detailed Implementation

[0024] Reference Figures 1-8This invention provides a technical solution: a test device for a permeable reactive wall filled with a novel material, PRB, comprising: a base 1; a drive chamber 2, fixed to one side of the base 1, with a drive cylinder 3 fixed inside; a fixing plate 4, fixed to the upper surface of the base 1 and disposed on the side of the base 1 near the drive chamber 2; a bottom plate 5, fixed to the upper surface of the base 1, located on one side of the fixing plate 4, with an adjusting cylinder fixed inside; at least two support members 6, all fixed to the bottom plate 5; an adjusting assembly 7, fixed to the side of the fixing plate 4 away from the drive chamber 2; an adjusting chamber 8, fixed to the side of the adjusting assembly 7 away from the fixing plate 4 and fixed by one of the support members 6, the inner wall of the adjusting chamber 8 having two sets of conversion grooves 81 symmetrically formed; and a drainage chamber 10, which is slidable. The adjustment assembly 7 is mounted on another support member 6 and located on the side of the adjustment chamber 8 away from the adjustment component 7; the clamping component 9 is mounted on the drainage chamber 10 and located on the side close to the adjustment chamber 8; the collection chamber 11 is detachably mounted on the drainage chamber 10 and located on the side of the drainage chamber 10 away from the clamping component 9; wherein, the adjustment component 7 includes a connecting cylinder 71, on which a water inlet 72 and a sewage outlet 73 are symmetrically opened, and a drive column 74 is slidably arranged inside the connecting cylinder 71. The drive column 74 is driven by the drive cylinder 3, and one end of the drive column 74 extends into the adjustment chamber 8 and is fixed with a conversion component 75. A filter disc 76 is detachably mounted on the side of the conversion component 75 close to the drive column 74, and the conversion component 75 is driven by a conversion groove 81.

[0025] In this embodiment, the conversion assembly 75 includes: a connecting post 751 fixed on the driving post 74, with a plurality of swirl vanes 753 fixed on its outer circumference; a sliding ring 752, with a plurality of swirl vanes 753 coaxially arranged on the connecting post 751; a limiting ring 754 fixed on the side of the sliding ring 752 away from the driving post 74, with a plurality of arc-shaped limiting grooves 755 formed on the circumference of the limiting ring 754; multiple conversion plates 756 configured, slidably disposed on the limiting grooves 755 by means of a sliding shaft 757, and corresponding one-to-one with the multiple limiting grooves 755; and a rotating ring 758 rotatably disposed on the side of the multiple conversion plates 756 away from the limiting ring 754, and slidably connected to the multiple conversion plates 756.

[0026] In other words, when the rotating ring 758 rotates, it drives multiple conversion plates 756 to slide along the limiting groove 755, thereby enabling the multiple conversion plates 756 to perform the conversion operation of opening and closing.

[0027] In a preferred embodiment, two sliding posts 7581 are symmetrically arranged on the side wall of the rotating ring 758. Both sliding posts 7581 are slidably connected to the rotating ring 758, and a pressing spring is provided between them. A guide block 7582 is rotatably arranged on the sliding post 7581. The guide block 7582 is slidably connected to the conversion groove 81, and the guide block 7582 is elliptical.

[0028] In a preferred embodiment, the conversion groove 81 includes a first sliding groove 811 and a second sliding groove 813, which are disposed away from the water inlet 72 and the drain outlet 73. A stepped groove 815 is provided at the end of each of the sliding grooves 811 and 813 away from the drive column 74. A drive groove 812 is provided at the end of the first sliding groove 811 away from the drive column 74. The drive groove 812 is a spiral groove, and its other end communicates with the end of the stepped groove 815 on the second sliding groove 813 away from the drive column 74. A drive groove 814 is provided at the end of the second sliding groove 813 away from the drive column 74. The drive groove 814 is a spiral groove, and its spiral direction is opposite to that of the first driving groove 812. The other end of the drive groove 814 communicates with the end of the stepped groove 815 on the first sliding groove 811 away from the drive column 74.

[0029] It should be noted that the length of the long side of the guide block 7582 is greater than the width of the sliding groove 1 811, the sliding groove 2 813, the drive groove 1 812, and the drive groove 2 814. The depth of the recess of the stepped groove 815 near the end of the sliding groove 1 811 and the sliding groove 2 813 is less than the depth of the recess of the stepped groove 815 away from the sliding groove 1 811 and the sliding groove 2 813, thereby facilitating the reciprocating motion of the guide block 7582 along the set trajectory.

[0030] In other words, when multiple conversion plates 756 are in the closed state, when the drive column 74 pushes the conversion assembly 75 to slide along the conversion groove 81, the guide block 7582 first slides in the first sliding groove 811, and then reaches the junction of the first sliding groove 811 and the first drive groove 812. At this time, the guide block 7582 rotates through the first drive groove 812, causing the guide block 7582 to enter the first drive groove 812. Then, the drive column 74 continues to push the conversion assembly 75 to slide, causing the guide block 7582 to drive the rotating ring 758 to rotate. When the guide block 7582 slides to the drive... After the junction of groove 812 and stepped groove 815, guide block 7582 falls into stepped groove 815. Then, drive column 74 pulls conversion component 75 to slide in the opposite direction. At this time, multiple conversion plates 756 complete the opening and closing operation. Then, guide block 7582 slides along sliding groove 813 to the initial position, completing the opening and closing conversion of conversion plate 756. And through the spiral direction of drive groove 812 and drive groove 814, the rotating ring 758 can be made to reciprocate, thereby completing the reciprocating opening and closing operation of drive conversion plate 756 for testing in different environments.

[0031] In this embodiment, the clamping assembly 9 includes: a sliding seat 91, slidably disposed on the drainage chamber 10 and driven by the adjusting motor; a mounting seat 92, fixed on the sliding seat 91; a fixing ring 93, fixed on the drainage chamber 10; a plurality of reset posts 94, circumferentially fixed on the fixing ring 93 and slidably connected to the sliding seat 91 and the mounting seat 92, and each reset post 94 is sleeved with a reset spring; a snap-fit ​​groove 95, formed on the side of the sliding seat 91 and the mounting seat 92 away from the fixing ring 93; and a test assembly 96, snapped into the snap-fit ​​groove 95.

[0032] During testing, the test component 96 is first snapped into the adjustment chamber 8. Then, the sliding seat 91 is driven to slide by the adjustment motor, which in turn drives the mounting seat 92 and the drainage chamber 10 to slide synchronously. This allows the sliding seat 91 and the mounting seat 92 to press and clamp the test component 96. The return spring provides a continuous preload force for clamping, thus providing dynamic compensation. This ensures that the sliding seat 91 and the mounting seat 92 can fit tightly against the test component 96, maintaining a seal even under high pressure or minor deformation of the component, thereby improving the sealing effect.

[0033] It should be noted that the regulating chamber 8 has a slot inside the end near the drainage chamber 10. The slot corresponds to the test component 96, which facilitates the snap-fit ​​of the test component 96. A sealing gasket is installed inside the slot, which works with the clamping component 9 to complete the sealing operation at both ends of the test component 96.

[0034] In a preferred embodiment, the test assembly 96 includes: a test chamber 961, the outer wall of which is fixed with a retaining plate 962, the retaining plate 962 being engaged in a retaining groove 95; and a permeation reaction wall 963, fixed inside the test chamber 961.

[0035] In other words, by fixing the permeation reaction wall 963 inside the test chamber 961, the permeation reaction wall 963 can be quickly replaced, thus improving testing efficiency.

[0036] In a preferred embodiment, the permeation reaction wall 963 is columnar and uses a combination of multiple different materials. A sealing component is provided at one end of the test chamber 961 near the drainage chamber 10. The sealing component is slidably disposed in the regulating chamber 8 and the drainage chamber 10 respectively.

[0037] In other words, by installing the permeation reaction wall 963 inside the test chamber 961, efficient and convenient modular testing can be achieved, which makes it easy to replace permeation reaction walls 963 with different material combinations or types, thus greatly improving the efficiency of testing.

[0038] In a preferred embodiment, the sealing assembly includes: a sealing ring 964, slidably disposed within the drainage chamber 10, with a plurality of pressing posts 965 fixed at one end away from the test chamber 961, the pressing posts 965 being slidably disposed within the drainage chamber 10, and a pressing spring sleeved on the outer wall of the pressing posts 965; a first sealing ring 966, at least three, installed on the outer wall of the sealing ring 964; and a second sealing ring, installed at the end of the sealing ring 964 near the test chamber 961.

[0039] In other words, when installing the test chamber 961, the sealing component located in the drainage chamber 10 is brought close to the test chamber 961 by adjusting the motor's push. Then, the end face of the test chamber 961 contacts the second sealing ring, and the push continues, causing the sealing ring 964 to slide until the snap-fit ​​groove 95 fits against the snap-fit ​​plate 962, completing the installation of the test chamber 961. This improves the sealing performance during testing, reduces the impact of the external environment on the test, and when clamping and sealing the test component 96, the clamping component 9 and the sealing component can provide a double seal for the test component 96, thereby significantly improving the sealing effect. Furthermore, the return spring and the pressing spring provide dual dynamic compensation during sealing, maintaining the sealing effect even under high pressure or minor deformation of the component. The return spring and the pressing spring can also clamp and seal test components 96 of different lengths for comparative testing or to meet specific specifications.

[0040] Specifically, firstly, the clamping component 9 quickly clamps the test component 96, facilitating comparative testing of various permeable reactive walls 963. The sealing component improves the sealing between the test component 96, the regulating chamber 8, and the drainage chamber 10, further enhancing test accuracy. Then, the conversion component 75 regulates the state of the wastewater entering the regulating chamber 8. When static groundwater simulation testing is required, the conversion component 75 is brought close to the connecting cylinder 71, allowing the inlet 72 to directly deliver groundwater wastewater between the conversion component 75 and the test component 96. The conversion component 75 is then pushed closer to the test component 96 via the drive column 74 to adjust the water pressure. Once the set value is reached, the drive column 74 is slowly pushed, ensuring that the amount of water pressure reduction as the wastewater passes through the test component 96 matches the rate at which the conversion component 75 approaches the test component 96, thus guaranteeing stable water pressure and improving simulation accuracy, until the collection chamber 11 completes collection.

[0041] When simulating the flow of groundwater, there are two testing methods. The first method is as follows: When only the decontamination capacity of the permeable reactive wall 963 is being tested, a filter plate 76 is installed to filter the sediment in the groundwater. The drive column 74 pushes the conversion component 75 closer to the test component 96. At this time, the conversion component 75 is opened through the conversion slot 81, and then water is introduced through the inlet 72, so that the wastewater is located between the connecting cylinder 71 and the conversion component 75. Then, the drive column 74 pulls the conversion component 75 closer to the connecting cylinder 71 at the same speed as the groundwater flow rate, thus completing the test of the decontamination capacity of the permeable reactive wall 963. The second method is as follows: When it is necessary to determine the overall decontamination capacity of the permeable reactive wall 963 for groundwater, the process remains the same. Before the test, the filter plate 76 is removed, allowing the sediment and wastewater to flow together. The vortex vane 753 mixes the sediment and wastewater to prevent the sediment from falling to the bottom of the regulating chamber 8 due to gravity, which would affect the test results. This accurately simulates the actual situation of groundwater flow and improves the test accuracy.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
