Description

Technical Field

[0001] The present invention relates to the technical field of soil detection, and specifically to a soil remediation experiment detection device and its detection method. Background Art

[0002] With the acceleration of industrialization and urbanization, the problem of heavy metal contaminated soil is becoming increasingly severe. Heavy metals such as lead, cadmium, mercury, chromium, etc. are difficult to degrade in the soil. They not only cause a decline in soil fertility and affect the growth of crops, but also enter the human body through the food chain, endangering human health. Currently, common soil heavy metal remediation technologies include physical remediation, chemical remediation, and biological remediation, etc. Physical remediation such as the soil replacement method has high costs and large engineering quantities; chemical remediation is prone to cause secondary pollution; traditional biological remediation has a long cycle and low efficiency. The electrokinetic remediation technology uses the action of an electric field to drive the migration of heavy metal ions, but when used alone, there are problems such as high energy consumption and limited remediation effect; the microbial remediation technology uses the adsorption, transformation, etc. of microorganisms on heavy metals for remediation, but the remediation speed is relatively slow. Therefore, it is of great significance to develop an efficient and environmentally friendly heavy metal contaminated soil remediation technology and device.

[0003] Currently, during the soil remediation experiment process, monitoring and detection are the keys to ensuring the remediation effect. However, the existing soil remediation experimental equipment and detection methods have certain deficiencies in aspects such as real-time monitoring of gas changes, monitoring of microbial populations, and precise control of the mixing process. Traditional monitoring means often rely on direct sampling and analysis of the soil itself. This method cannot track the changes in gas during the remediation process in real time, nor can it effectively judge the mixing degree of the remediation agent and the soil. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the present invention provides a soil remediation experiment detection device and its detection method, which solve the problem that the traditional method mainly relies on sampling and analysis of the soil itself, fails to track the changes in gas components during the soil remediation process in real time, and cannot accurately judge whether the remediation process is fully mixed or whether there is the release of harmful gases.

[0006] By adopting the above technical solutions:

[0007] First of all, the traditional method mainly relies on the sampling and analysis of the soil itself, fails to track the changes in gas components during the soil remediation process in real time, and cannot accurately judge whether the remediation process is fully mixed or whether there is the release of harmful gases. During the use of this device, in view of the problems of the existing technology, it is increased that the remediation liquid can be added during the experimental mixing process by shunting, and at the same time, gas can be extracted. Therefore, during the use process, not only can the problem that the existing technology cannot collect gas for detection be solved, but also the effect of being able to add different gases for experiments according to different usage situations can be achieved.

[0008] Preferably, the screening component includes a first motor, the outer wall of the first motor is fixedly connected to the outer wall of the housing, the output end of the first motor is fixedly provided with a reciprocating rod, and one end of the reciprocating rod is rotatably connected with a mounting gripper.

[0009] Preferably, a screen is detachably installed on the lower surface of the mounting gripper, and the output end of the mounting gripper is fixedly connected with a slide rail.

[0010] Preferably, the outer wall of the slide rail is slidably connected to the inside of the housing, a vertical plate is arranged below the slide rail, and the outer wall of the vertical plate is slidably connected to the middle of the housing.

[0011] Preferably, the reaction assembly includes a vertical plate, the lower surface of the vertical plate is fixedly connected to the upper surface of the housing, a second motor is fixedly connected to one side of the vertical plate, the output end of the second motor is fixedly connected to a mounting frame, and a reaction tank is detachably mounted on the inner wall of the mounting frame. A ball valve is provided in the middle of the connecting pipe, and one opening of the connecting pipe is arranged inside the reaction tank.

[0012] Preferably, a sealing cover is provided at the top of the reaction tank, a protective shell is fixedly connected to the upper surface of the sealing cover, and a third motor is fixedly connected to the inner top wall of the protective shell.

[0013] Preferably, the output end of the third motor is connected to a worm, the tooth end of the worm is meshed with a worm gear, and a centrifugal rod is fixedly connected to the outer wall of one side of the worm gear.

[0014] Preferably, an adjusting bracket is rotatably connected to the inner wall of the centrifugal rod, an adjusting claw is fixedly connected to the outer wall of the adjusting bracket, an adjusting rod is arranged on the outer wall of the adjusting claw, and the inner part of the adjusting rod is slidably arranged on the lower outer wall of the worm.

[0015] Preferably, a mixing column is fixedly connected to the outer wall of the adjusting rod, the lower end of the worm is square, the inner part of the adjusting rod is slidably connected with the end of the worm in a matching manner, a side column is fixedly connected to the bottom end of the adjusting rod, and the outer wall of the side column is slidably connected to the outer wall of the reaction tank.

[0016] A soil remediation experimental detection method includes the following steps:

[0017] First, open the sealing cover and add the soil to be detected and repaired into the reaction tank. Then, install the sealing cover back into the reaction tank by using bolts. Then, start the second motor for preliminary mixing. During the mixing process, the repair liquid can be added through the liquid treatment tank for mixing. At the same time, the repair liquid or biological repair fungi are pumped into the switching cavity through the water pump inside the liquid treatment tank. Then, the liquid pushes the first sealing surface to drive the connecting rod and the second sealing surface to move to the other side. Thus, during use, the liquid is injected into the reaction tank through the switching cavity and the connecting pipe. After that, further drive the worm and the worm gear by the third motor to drive the centrifugal rod and the adjusting bracket. During the rotation of the worm gear, drive the centrifugal rod to move up and down, so as to drive the adjusting rod and the mixing column to move up and down during use, and further mix the mixed liquid with the repaired soil. After mixing, reset, and discharge the mixed soil through the lower discharge port;

[0018] During the use process, air samples can be extracted for further detection. Through the air samples, it can be determined whether the repair agent and the soil are fully mixed, and whether the microbial population remains in the air. This can serve as a way for further experimental judgment. By starting the gas collection box, the second sealing surface, the connecting rod, and the first sealing surface are driven to move to the other side, avoiding cross-contamination of the pipeline during use. The gas is injected through the gas collection box. During the experiment, it is observed whether the soil will have other reactions under special gases, including nitrogen and pure oxygen, to increase the diversity of the experiment. At the same time, gas samples can be taken out from the reaction tank through reverse suction. During use, fine dust in the reaction tank during mixing will cause dust to fly due to stirring. When extracting gas samples, the dust can be intercepted by the filter element. By closing the ball valve and starting the liquid treatment box to transport the liquid in, the filter element can be cleaned during use. At the same time, when performing biological and chemical repair of the liquid medicine, the filter element also has the function of intercepting particles that are not fully stirred. After the gas is extracted, the soil is discharged;

[0019] Through the feeding port provided in the middle of the outer shell, the soil falls on the sieve mesh. At this time, the first motor is started to drive the reciprocating rod to drive the installation claw. The installation claw reciprocates under the drive of the reciprocating rod and slides under the limit of the slide rail, thereby driving the installation claw on the other side to move. During the use process, the sieve mesh is driven to perform sieving, so as to separate soils of different fineness for sampling and detection. At the same time, during the use process, a set of gas collection box and liquid treatment box are also provided on the right side, which can absorb the dust raised through the gas collection box and intercept it through the filter screen during the sieving process, thereby reducing the impact of dust on the experimental environment, and the filter screen is rinsed through the liquid treatment box. The soil repair sample after sieving is collected through the collection box below for centralized treatment.

[0020] The present invention provides a soil repair experimental detection device and its detection method. It has the following beneficial effects:

[0021] 1. Through gas collection and sample analysis, the present invention monitors the gas changes during the repair process, realizes that through real-time detection of gas samples, it can be determined whether the soil is fully mixed during the soil repair process and whether the microbial population exists in the air, further optimizes the effect of the soil repair experiment, reduces air pollution, and improves the accuracy of the experiment.

[0022] 2. By controlling the switching of liquid and gas, the present invention enhances the accuracy of soil repair. Under the synergistic action of liquid and gas, the automatic switching and transportation of liquid and gas are realized, making the mixing of the repair liquid and the soil more uniform, optimizing the repair effect, and effectively preventing cross-contamination of different repair agents.

[0023] 3. The present invention screens the fineness of the soil through a screening component to improve the quality of the repair samples. Through an adjustable screen and a motor drive system, the soil can obtain samples with different finenesses for precise analysis after screening, thereby enhancing the standardization and consistency of the soil repair effect.

[0024] 4. Through the application of the filter element, the present invention effectively removes dust and particulate matter, maintaining the purity of the experimental environment. When extracting gas samples, the filter element can effectively intercept the dust and particulate matter generated during the experiment, ensuring the quality of the gas samples and the cleanliness of the experimental environment, and enhancing the reliability and repeatability of the experiment.

Detailed implementation manners

[0035] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0036] Please refer to the attached Figure 1 - attached Figure 4 and Figure 6 , an embodiment of the present invention provides a soil remediation experiment detection device, including a mounting plate 1, a transfer sleeve 2 is fixedly connected to the inner wall of the mounting plate 1, a filter element 8 is arranged inside the transfer sleeve 2, a connecting sleeve 3 is detachably installed on the lower side of the transfer sleeve 2, a switching cavity 4 is arranged on the lower side of the connecting sleeve 3, a first sealing surface 5 is slidably arranged inside the switching cavity 4, a connecting rod 6 is arranged on one side of the first sealing surface 5, a second sealing surface 7 is fixedly arranged on the other side of the connecting rod 6, the outer wall of the second sealing surface 7 is slidably arranged on the inner wall of the switching cavity 4, an overflow pipe 9 penetrates through one side of the mounting plate 1, a through hole inside the overflow pipe 9 extends to the inside of the transfer sleeve 2, a connecting pipe 12 is arranged at the upper opening of the transfer sleeve 2, the other opening of the through hole of the overflow pipe 9 is provided with a collection box 10, a gas collection box 13 is arranged on one side of the switching cavity 4, a liquid treatment box 14 is arranged on the other side of the switching cavity 4, the lower surfaces of the liquid treatment box 14 and the gas collection box 13 are fixedly connected with a housing 11, a screening assembly is arranged in the middle of the housing 11, and a reaction assembly is arranged on the upper side of the housing 11.

[0037] Specifically, first install the filter element 8 inside the transfer sleeve 2, and then install it inside the outer shell 11 through the mounting plate 1 by means of bolts or the like, and dock it with the lower side of the connecting pipe 12. Then, during use, according to the experimental requirements, open the gas collection box 13 or the liquid treatment box 14, and use the gas or liquid to push the first sealing surface 5 or the second sealing surface 7 to drive the connecting rod 6 to drive the other side to move, so as to block the pipeline on the other side, which can avoid cross-contamination and improve the diversity of experiments during use. When it is necessary to extract gas for experiments during use, first start the gas collection box 13 to drive the second sealing surface 7 to push the first sealing surface 5 to the other side, then reduce the air pressure, and the pressure of the air pressure is half of the pushing pressure, and then extract the gas inside the reaction tank 21. During use, due to the connection of the pipeline, the second sealing surface 7 and the first sealing surface 5 will not move due to the pressure. During use, the filter element 8 intercepts the particles during gas extraction. When it is necessary to clean the filter element 8, close the ball valve 24 and start the liquid treatment box 14 to drive the first sealing surface 5 to move to the other side, and wash it with water flow. Because the sewage under the upper pressure can only flow to the collection box 10 through the overflow pipe 9, the experimental method can be quickly switched according to different usage situations during use. After adding biological or chemical repair liquid into the liquid treatment box 14, the liquid is transported to the inside of the reaction tank 21 through the liquid treatment box 14 and the connecting pipe 12 for mixing with the soil. During use, rapid mixing experiments can be carried out according to different repair substrates, and gas samples can be extracted by extracting gas during the experiment, so as to judge the repair environment and the effect of the repair result according to the gas samples at different time periods.

[0038] Please refer to the attached Figure 1 and the attached Figure 7 As shown in the figure, the screening assembly includes a first motor 15. The outer wall of the first motor 15 is fixedly connected to the outer wall of the outer shell 11. The output end of the first motor 15 is fixedly provided with a reciprocating rod 16. One end of the reciprocating rod 16 is rotatably connected to a mounting claw 17. A screen 19 is detachably mounted on the lower surface of the mounting claw 17. The output end of the mounting claw 17 is fixedly connected to a slide rail 18. The outer wall of the slide rail 18 is slidably connected to the inside of the outer shell 11. A vertical plate 20 is arranged below the slide rail 18. The outer wall of the vertical plate 20 is slidably connected to the middle of the outer shell 11.

[0039] Specifically, first, start the first motor 15 to drive the reciprocating rod 16, so that the mounting gripper 17 moves back and forth along the slide rail 18 inside the housing 11, driving the screen 19 to perform the screening operation. Through this screening, different fineness soil particles can be separated during use, so as to conduct subsequent soil remediation sample sampling and detection. During the screening process, the raised dust and fine particles will be captured in time to avoid polluting the experimental environment and affecting the experimental results. The vertical plate 20 slides with the inner wall of the housing 11, further ensuring the stability of the screening assembly and avoiding deviation or unevenness during the screening process. During the screening operation, the combined use of the gas collection box 13 and the liquid treatment box 14 can effectively control the extraction and filtration of gas, ensuring that the soil sample will not be affected by the external environment. The screened soil sample is collected by the collection box 10 below for centralized treatment, providing reliable repair effect data, making the screening process of the soil remediation experiment more accurate and efficient during use, and at the same time effectively reducing the pollution of the experimental environment and optimizing the soil remediation effect.

[0040] Please refer to the attached Figure 1 attachment Figure 8 and attachment Figure 9 As shown in the figure, the reaction assembly includes a vertical plate 20. The lower surface of the vertical plate 20 is fixedly connected to the upper surface of the housing 11. One side of the vertical plate 20 is fixedly connected with a second motor 22. The output end of the second motor 22 is fixedly connected with a mounting frame 23. The inner wall of the mounting frame 23 is detachably installed with a reaction tank 21. A ball valve 24 is arranged in the middle of the connecting pipe 12. One opening side of the connecting pipe 12 is arranged inside the reaction tank 21. The top of the reaction tank 21 is provided with a sealing cover 25. The upper surface of the sealing cover 25 is fixedly connected with a protective shell 26. The inner top wall of the protective shell 26 is fixedly connected with a third motor 27. The output end of the third motor 27 is connected with a worm 28. The tooth end of the worm 28 is meshed with a worm gear 29. One outer wall of the worm gear 29 is fixedly connected with a centrifugal rod 30.

[0041] Specifically, first, open the vertical plate 20 to add the soil to be repaired or detected into the reaction tank 21, and then reset the vertical plate 20. During use, drive the mounting frame 23 to rotate through the second motor 22, so as to drive the reaction tank 21 to rotate during use. During use, the soil deposited at the bottom can be turned over. At the same time, drive the worm gear 29 and the adjustment bracket 31 through the reaction tank 21 and the worm 28 to control the mixing column 34 to rotate while moving up and down. During use, the uniformity of soil mixing is further increased. During use, the biological remediation liquid or chemical remediation liquid can be quickly mixed with the soil, further increasing the experimental speed and reducing the experimental period during use.

[0042] Please refer to the attached Figure 9, a regulating bracket 31 is rotatably connected to the inner wall of the centrifugal rod 30. An adjusting claw 32 is fixedly connected to the outer wall of the regulating bracket 31. An adjusting rod 33 is arranged on the outer wall of the adjusting claw 32. The inside of the adjusting rod 33 is slidably arranged on the lower outer wall of the worm 28. A mixing column 34 is fixedly connected to the outer wall of the adjusting rod 33. The lower end of the worm 28 is square. The inside of the adjusting rod 33 is slidably connected to the end of the worm 28 in a matching manner. A side column 35 is fixedly connected to the bottom end of the adjusting rod 33. The outer wall of the side column 35 is slidably connected to the outer wall of the reaction tank 21.

[0043] Specifically, when the centrifugal rod 30 is driven, it drives the regulating bracket 31 at the same time. When the worm gear 29 rotates, it drives the centrifugal rod 30 to perform a centrifugal motion, thereby driving the regulating bracket 31 to move up and down. During the movement, because the square shape at the lower end of the worm 28 drives the adjusting rod 33 to rotate, and through the up and down movement, it drives the adjusting rod 33 to move up and down during the rotation process. By synchronously driving the side column 35 to rotate through the adjusting rod 33, the soil on both sides can be stirred, and at the same time, the side column 35 can also clean the inner wall of the reaction tank 21. During use, it can further avoid the situation that the soil on the side cannot be mixed, and can further increase the soil mixing effect during use.

[0044] Please refer to the appendix Figure 1 - appendix Figure 9 , a soil remediation experimental detection method, including the following steps:

[0045] First, open the sealing cover 25 and add the soil to be detected and repaired into the reaction tank 21. Then, install the sealing cover 25 back into the reaction tank 21, which can be installed with bolts. Then, start the second motor 22 for preliminary mixing. During the mixing process, the repair liquid can be added through the liquid treatment tank 14 for mixing. At the same time, the repair liquid or biological repair fungi are pumped by the water pump inside the liquid treatment tank 14 into the switching cavity 4. Then, the liquid pushes the first sealing surface 5 to drive the connecting rod 6 and the second sealing surface 7 to move to the other side. Thus, during use, the liquid is injected into the reaction tank 21 through the switching cavity 4 and the connecting pipe 12. After that, further drive the worm 28 and the worm gear 29 by the third motor 27 to drive the centrifugal rod 30 and the regulating bracket 31. When the worm gear 29 rotates, it drives the centrifugal rod 30 to move up and down, thereby driving the adjusting rod 33 and the mixing column 34 to move up and down during use, so that the mixed liquid and the repaired soil are further mixed. After mixing, reset, and discharge the mixed soil through the lower discharge port;

[0046] During the use process, further detection can be carried out by extracting air samples. Through the air samples, it can be judged whether the repair agent and the soil are fully mixed, and whether the microbial population remains in the air. This can be used as a way for further experimental judgment. By starting the gas collection box 13, the second sealing surface 7, the connecting rod 6, and the first sealing surface 5 are driven to move to the other side, avoiding cross-contamination of the pipeline during use. The gas is injected through the gas collection box 13. During the experiment, it is observed whether the soil will have other reactions under special gases, including nitrogen and pure oxygen, improving the diversity in the experiment. At the same time, gas samples can be taken out from the inside of the reaction tank 21 by reverse suction. During use, fine dust in the reaction tank 21 will cause dust to fly due to stirring. When extracting gas samples, the dust can be intercepted by the filter element 8. By closing the ball valve 24 and starting the liquid treatment box 14 to convey the liquid in, the filter element 8 can be cleaned during use. At the same time, when performing biological and chemical repair of the liquid medicine, the filter element 8 also has the function of intercepting particles that are not fully stirred. After the gas is extracted, the soil is discharged;

[0047] Through the feeding port provided in the middle of the outer shell 11, the soil falls on the sieve mesh 19. At this time, the first motor 15 is started to drive the reciprocating rod 16 to drive the installation gripper 17. The installation gripper 17 reciprocates under the drive of the reciprocating rod 16 and slides under the limit of the slide rail 18, thereby driving the installation gripper 17 on the other side to move. During the use process, the sieve mesh 19 is driven to perform sieving, so as to separate soils with different finenesses for sampling and detection. At the same time, during the use process, a set of gas collection box 13 and liquid treatment box 14 are also provided on the right side, which can absorb the dust raised by oxygen through the gas collection box 13 during sieving and intercept it through the filter screen, thereby reducing the impact of dust on the experimental environment, and the filter screen is rinsed by the liquid treatment box 14. The sieved soil repair samples are collected through the collection box 10 below for centralized treatment.

The bottom end of the adjusting rod (33) is fixedly connected to a side column (35). The outer wall of the side column (35) is slidably connected to the outer wall of the reaction tank (21).

10. A soil remediation experimental detection method, characterized in that, Applied to a soil remediation experimental detection device according to any one of claims 1-9, it includes the following steps: First, open the sealing cover (25) and add the soil to be detected and repaired into the reaction tank (21). Then, install the sealing cover (25) back into the reaction tank (21), which can be installed with bolts. Then, start the second motor (22) for preliminary mixing. During the mixing process, the repair liquid can be added through the liquid treatment tank (14) for mixing. At the same time, the repair liquid or biological repair fungi are transported to the inside of the switching cavity (4) through the water pump inside the liquid treatment tank (14). Then, the first sealing surface (5) is driven by the liquid to drive the connecting rod (6) and the second sealing surface (7) to move to the other side. Thus, during use, the liquid is injected into the reaction tank (21) through the switching cavity (4) and the connecting pipe (12). After that, the third motor (27) further drives the worm (28) and the worm gear (29) to drive the centrifugal rod (30) and the adjusting bracket (31). During the rotation of the worm gear (29), the centrifugal rod (30) moves up and down, thereby driving the adjusting rod (33) and the mixing column (34) to move up and down during use, so that the mixed liquid and the repaired soil are further mixed. After mixing, reset, and discharge the mixed soil through the lower discharge port; During the use process, further detection can be carried out by extracting air samples. Through the air samples, it can be judged whether the repair agent and the soil are fully mixed, and whether the microbial population remains in the air, which can be used as a way for further experimental judgment. By starting the gas collection box (13), the second sealing surface (7), the connecting rod (6) and the first sealing surface (5) are driven to move to the other side, avoiding cross-contamination of the pipeline during use. The gas collection box (13) injects gas, and in the experiment, it is observed whether the soil will have other reactions under special gases, including nitrogen and pure oxygen, improving the diversity in the experiment. At the same time, the gas sample can be taken out from the inside of the reaction tank (21) by reverse suction. During use, fine dust in the reaction tank (21) will cause dust to fly due to stirring. When extracting the gas sample, the dust can be intercepted by the filter element (8). By closing the ball valve (24) and starting the liquid treatment box (14), the liquid is transported in, and the filter element (8) can be cleaned during use. At the same time, when performing biological and chemical repair of the liquid medicine, the filter element (8) also has the function of intercepting the particles that are not fully stirred. After extracting the gas, the soil is discharged; Through the feeding port provided in the middle of the outer shell (11), the soil falls on the sieve (19). At this time, the first motor (15) is started to drive the reciprocating rod (16) to drive the mounting claw (17). The mounting claw (17) reciprocates under the drive of the reciprocating rod (16). The mounting claw (17) slides under the limit of the slide rail (18), thereby driving the mounting claw (17) on the other side to move. During the use process, the sieve (19) is driven to perform sieving, so as to separate soils with different finenesses for sampling and detection. At the same time, during the use process, a set of gas collection box (13) and liquid treatment box (14) are also provided on the right side, which can absorb the dust raised by oxygen through the gas collection box (13) and intercept it through the filter screen during the sieving process, thereby reducing the impact of dust on the experimental environment, and the liquid treatment box (14) is used to wash the filter screen. The sieved soil repair sample is collected through the collection box (10) below for centralized treatment.
