Description

Technical Field

[0001] This invention belongs to the technical field of synthetic packaging material blockage, specifically relating to a device and method for visualizing the blockage process of synthetic packaging materials. Background Technology

[0002] Concealed drainage systems are widely used in engineering geology, sponge city projects, environmental protection, and farmland drainage. Synthetic cladding is a highly permeable material placed around the concealed pipes to ensure their permeability and prevent clogging. However, synthetic cladding inevitably encounters clogging problems during use, which reduces the drainage and desalination efficiency of the concealed pipes, increases maintenance costs, and shortens their lifespan. Given the widespread application of concealed drainage systems, it is crucial to elucidate the clogging mechanism of synthetic cladding to provide a basis for its prevention and control.

[0003] Existing research on the clogging of synthetic cladding materials in underground pipes mainly uses soil column or sand box seepage tests to statistically analyze the permeability coefficient and clogging amount of the synthetic cladding material before and after clogging. For example, Xiao Mingqing et al. disclosed a method for measuring chemical clogging of geotextiles (CN202010076193.4), which measures the effect of chemical clogging by laying geotextile on the bottom of a self-made test chamber and then injecting an ionic solution into the chamber; by adding soil samples to the chamber, compacting them, and then introducing an ionic solution, the physical and chemical coupling of clogging is simulated. However, this method cannot directly observe the development process of clogging and is not suitable for quantifying clogging processes with rapid development, thus hindering the accurate generalization of the clogging process of synthetic cladding materials. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a visualization device for the blockage process of synthetic outer packaging materials. This device can observe the blockage process on the synthetic outer packaging materials in dark pipes in real time, and can also simulate the blockage process with a relatively fast development speed.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A visualization device for the clogging process of synthetic packaging materials, comprising:

[0007] The first supply tank is filled with the first solution as needed;

[0008] The second supply tank is filled with the first solution as needed;

[0009] A transparent reaction column is provided with a first inlet, a second inlet, and an outlet. The first inlet is connected to a first supply tank via a first peristaltic pump, and the second inlet is connected to a second supply tank via a second peristaltic pump. A synthetic outer packaging material is arranged radially inside the reaction column, dividing it into two parts. The first and second inlets are located on one part of the reaction column, and the outlet is located on the other part.

[0010] The imaging device includes a camera for filming the clogging process of the synthetic packaging material, the camera being positioned at a height comparable to the height of the visualization reaction column; and a waste liquid collection tank connected to the outlet.

[0011] Furthermore, the visualized reaction column also includes a transparent outer sleeve, a first inner sleeve, a second inner sleeve, a first sealing cap, and a second sealing cap. A first liquid inlet and a second liquid inlet are disposed on the outer sleeve. The first inner sleeve and the second inner sleeve are axially connected and placed inside the outer sleeve. The synthetic outer packaging material is disposed between the first inner sleeve and the second inner sleeve. A first through hole communicating with the first liquid inlet and a second through hole communicating with the second liquid inlet are provided on the side wall of the second inner sleeve. The first sealing cap seals the end of the outer sleeve away from the second inner sleeve, and the second sealing cap seals the other end of the outer sleeve away from the first inner sleeve. A first liquid outlet is disposed on the first sealing cap.

[0012] Furthermore, the first liquid inlet, the second liquid inlet, the first through hole, and the second through hole are all located close to the second sealing cover.

[0013] Furthermore, the first sealing cover is also provided with an exhaust port.

[0014] Furthermore, it also includes a panel light, which is positioned on one side of the visualization reaction column to provide the illumination required for image acquisition.

[0015] Furthermore, the shooting device also includes an image acquisition device and an image processing device electrically connected to the image acquisition device, the image acquisition device being electrically connected to a camera.

[0016] Another object of the present invention is to provide a visualization method for the above-described synthetic packaging material clogging process visualization device, comprising the following steps:

[0017] S1. Install the synthetic outer packaging material to be observed on the radial section inside the visualization reaction column, and then fix the visualization reaction column on the worktable;

[0018] S2. Fix the shooting device on the worktable and adjust the relative position between the camera lens and the synthetic outer packaging material to make the camera lens field of view clear;

[0019] S3. Based on the type of blockage, prepare the first reaction solution and / or the second reaction solution that causes the blockage, and store them in the first supply tank and / or the second supply tank for later use.

[0020] S4. Set and adjust the flow rate of the first peristaltic pump and / or the second peristaltic pump to pump the liquid from the first and second supply tanks into the visualization reaction column separately through the first or second inlet on the side wall of the reaction column, or pump the liquid from the first and second supply tanks into the visualization reaction column simultaneously for reaction. Then, take pictures of the surface blockage of the synthetic outer packaging material with a camera at fixed time intervals Δt until the blockage process ends. During the shooting process, the liquid passing through the synthetic outer packaging material flows from the outlet into the waste liquid collection tank.

[0021] Furthermore, in step S3, the types of clogging include physical clogging, chemical clogging, biological clogging, and combined clogging.

[0022] Furthermore, physical clogging scenarios are simulated by preparing a suspension containing soil particles, filling it into a first or second supply tank, pumping it into a visual reaction column, and then using a synthetic outer packaging material. Chemical clogging scenarios are simulated by preparing a first ion solution in the first supply tank, preparing a second ion solution in the second supply tank, pumping them together into the visual reaction column, and then using a synthetic outer packaging material. Biological clogging scenarios are simulated by preparing a mixed solution of microbial strains and nutrient solution in the first or second supply tank, pumping it into the visual reaction column, and then using a synthetic outer packaging material. Composite clogging scenarios are simulated by mixing the above two or three methods in pairs.

[0023] Furthermore, the first ionic solution is a CaCl2 solution, and the second ionic solution is a NaHCO3 solution.

[0024] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0025] (1) The synthetic outer packaging material blockage process visualization reaction column device designed in this invention is made of transparent material. The synthetic outer packaging material is placed in the middle of the reaction column through inner and outer sleeves.

It can realize quantitative simulation of blockage and avoid the interference of image acquisition on the blockage process. It can also realize continuous shooting and control of the camera and visualize the blockage process of synthetic outer packaging material.

[0026] (2) The visualization method for the clogging process of synthetic packaging material provided by the present invention can reproduce various clogging scenarios such as physical, chemical, biological or composite clogging of synthetic packaging material by passing soil particle suspension, ion solution, microbial strain and nutrient solution alone or in combination through synthetic packaging material; and can also simulate the clogging process of synthetic packaging material under different conditions by changing the type, concentration, temperature and flow rate of the solution.

[0032] The present invention will be further described below with reference to specific embodiments, but these are not intended to limit the scope of the invention.

[0033] like Figure 1 As shown, this embodiment of the invention discloses a visualization device for the clogging process of synthetic packaging materials, including a first supply tank 1, a second reaction tank 2, a visualization reaction column 3, a camera, and a waste liquid collection tank 4. A first solution is added to the first supply tank 1 as needed, and a second solution is added to the second supply tank 2 as needed. See [link / reference] Figure 3The visualized reaction column 3 is a transparent reaction column, comprising an outer sleeve 300, a first inner sleeve 301, a second inner sleeve 302, a synthetic outer packaging material 303, a first sealing cap 304, and a second sealing cap 305. All of these components are made of transparent material. A first liquid inlet 306 and a second liquid inlet 307 are provided on one side wall of the outer sleeve 300. The first inner sleeve 301 and the second inner sleeve 302 are axially connected and placed inside the outer sleeve 300, meaning the outer sleeve 300 encloses the first inner sleeve 301 and the second inner sleeve 302 within it. The inner and outer diameters of the first inner sleeve 302 and the second inner sleeve 302 are the same, and their outer diameters are approximately 0.5 mm smaller than the inner diameter of the outer sleeve. The synthetic outer packaging material 303 is disposed between the first inner sleeve 301 and the second inner sleeve 302, that is, the first inner sleeve 301, the synthetic outer packaging material 303, and the second inner sleeve 302 are sequentially connected along the axial direction of the outer sleeve 300. A first through hole 308 communicating with the first liquid inlet 306 and a second through hole 309 communicating with the second liquid inlet 307 are provided on the side wall of the second inner sleeve 302. A first sealing cap 304 seals one end of the outer sleeve 300 away from the second inner sleeve 302, and a second sealing cap 304 seals the other end of the outer sleeve 300 away from the first inner sleeve 301. An outlet 310 is provided on the first sealing cap 304. To ensure thorough mixing of the solution upon reaching the synthetic outer packaging material 303, the first liquid inlet 306, the second liquid inlet 307, the first through hole 308, and the second through hole 309 are all positioned as close as possible to the second sealing cap 305. In addition, an exhaust port 311 is provided on the first sealing cap 304 to facilitate the flow of liquid within the visualization reaction column 3. The first supply tank 1 is connected to the visualization reaction column 3 via a first peristaltic pump 5, which has a first inlet 306. The first peristaltic pump 5 is used to pump the solution in the first supply tank 1 into the visualization reaction column 3 through the first inlet 306. The second supply tank 2 is connected to the visualization reaction column 3 via a second peristaltic pump 6, which is used to pump the solution in the second supply tank 2 into the visualization reaction column 3 through the second inlet 307.

[0034] The imaging device includes a CCD camera 7 for capturing images of the clogging process of the synthetic outer packaging material, an image acquisition device 8, and an image processing device 9 electrically connected to the image acquisition device 8. The image acquisition device 8 is electrically connected to the CCD camera 7. The CCD camera 7 is positioned at a height approximately equal to the height of the visualization reaction column 3, with its lens aimed at the cross-section of the synthetic outer packaging material to capture images of the clogging situation. The CCD camera 7 transmits the captured images to the image acquisition device 8, which receives the image information and transmits it to the image processing device 9 for display. Furthermore, the image processing device 9 can control the shooting interval of the CCD camera 7 via the image acquisition device 8. To ensure clearer images captured by the CCD camera 7, a panel light 10 is provided on one side of the visualization reaction column 3. The panel light 10 provides the necessary illumination for image acquisition by the CCD camera 7, and its intensity can be adjusted as needed.

[0035] Taking the chemical clogging process of synthetic caulking materials, mainly composed of calcium and magnesium precipitation in the outer caulking material of drainage pipes in arid areas, as an example, the visualization method of the visualization device for the clogging process of synthetic caulking materials is explained. The specific implementation steps are as follows:

[0036] S1. The synthetic outer packaging material 303 to be observed is clamped between the first inner sleeve 301 and the second inner sleeve 302, and then the visualization reaction column 3 is fixed on the worktable.

[0037] S2. After adjusting the visualization reaction column 3, position the lens of the fixed-focus CCD camera 7 at a height comparable to that of the visualization reaction column 3. Adjust the camera's focal length, exposure intensity, and panel light source brightness to ensure the camera captures a clear image of the composite material 303. Preview the image of the composite material 303 at this point. Figure 3 (a).

[0038] S3. Prepare 1L of 0.02mol / L CaCl2 solution and 1L of NaHCO3 solution respectively, and filter them through a 0.45μm filter membrane. After filtration, put the CaCl2 solution into the first supply tank 1 and the NaHCO3 solution into the second supply tank 2.

[0039] S4. Before introducing the reaction solution, remove air bubbles from the synthetic outer packaging material 303. Set the flow rates of the first peristaltic pump 5 and the second peristaltic pump 6 to 0.3 ml / min. The first peristaltic pump 5 pumps the CaCl2 solution from the first supply tank 1 into the visualization reaction column 3 through the first inlet 306. Simultaneously, the second peristaltic pump 6 pumps the NaHCO3 solution from the second supply tank 2 into the visualization reaction column 3 through the second inlet 307. CaCl2 and NaHCO3 react fully in the visualization reaction column 3 and pass through the synthetic outer packaging material 303. Take a picture of the surface morphology of the synthetic outer packaging material 303 at this time. Then, take pictures of the synthetic outer packaging material at fixed time intervals of 10 min until the clogging process ends. Obtain images of the chemical clogging process of the synthetic outer packaging material 303. See [link to image]. Figure 3 During filming, the liquid from the synthetic outer packaging material 303 flows from the outlet 310 into the waste liquid collection tank 4. In other embodiments, the chemical clogging process of the synthetic outer packaging material 303 under different conditions can be simulated by changing the solution concentration, temperature, and the flow rates of the first peristaltic pump 5 and the second peristaltic pump 6.

[0040] The difference in the above embodiments is that a suspension containing soil particles is prepared in the first supply tank 1 or the second supply tank 2, and then the suspension containing soil particles is pumped into the visualization reaction column 3 by the first peristaltic pump 5 or the second peristaltic pump 6. The suspension containing soil particles passes through the synthetic outer packaging material 303, and the CCD camera 7 captures the physical blockage on the synthetic outer packaging material 303.

[0041] The difference in the above embodiments is that a mixed solution of microbial strains and nutrient solution is prepared in the first supply tank 1 or the second supply tank 2, and then the mixed solution of microbial strains and nutrient solution is pumped into the visualization reaction column 3 by the first peristaltic pump 5 or the second peristaltic pump 6. The mixed solution of microbial strains and nutrient solution passes through the synthetic outer packaging material 303, and the CCD camera 7 captures the bioclogging process on the synthetic outer packaging material 303.

[0042] In addition, composite clogging scenarios can be simulated by mixing the above two or three methods.

[0043] The above are merely preferred embodiments of the present invention and do not limit the implementation methods and scope of protection of the present invention. Those skilled in the art should recognize that all equivalent substitutions and obvious changes made based on the description of this invention should be included within the scope of protection of the present invention.
