Description

Technical Field

[0001] The present invention belongs to the technical field of soil detection, and in particular relates to a composite contaminated soil processing and detection device. Background Art

[0002] Ecological restoration is a comprehensive method of repairing polluted environments, guided by ecological principles, based on biological restoration, and combining various physical restoration, chemical restoration, and engineering and technical measures to achieve the best results and lowest costs through optimized combination. The smooth implementation of ecological restoration requires the participation of multiple disciplines such as ecology, physics, chemistry, botany, microbiology, molecular biology, cultivation, and environmental engineering. The repair and maintenance of damaged ecosystems involves a variety of ecological theories such as ecological stability, ecological plasticity, and steady-state transformation.

[0003] The most critical link in ecological restoration is soil "diagnosis," or soil testing. Scientific and accurate soil testing not only provides a basis for decision-making on restoration plans but also serves as the foundation and prerequisite for the entire ecological restoration process. Through systematic testing and analysis, technicians can accurately determine the types, concentrations, and spatial distribution characteristics of pollutants in the soil, and thus formulate targeted treatment strategies.

[0004] Currently, soil testing typically involves evaporating the soil at high temperatures. The resulting gas is extracted using an air pump and injected into a chromatograph for gas chromatography analysis. However, the sampled soil is deposited directly on a heated surface, where the soil thickness varies. This results in uneven heating, which in turn affects the accuracy of test results. Summary of the Invention

[0045] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0046] Please also refer to Figures 1 to 6 The present invention provides a device for processing and detecting composite contaminated soil. The device comprises a chromatograph, an evaporation unit 10, and a feed box 20. The evaporation unit 10 comprises an evaporation box 101 connected to an air inlet of the chromatograph, an evaporation tray 102 rotatably connected to the evaporation box 101, and a first drive member 103 transmission-connected to the evaporation tray 102. The first drive member 103 drives the evaporation tray 102 to rotate in an up-and-down direction. The feed box 20 is disposed through the evaporation box 101 and is fixedly connected to the evaporation box 101. The feed box 20 extends radially from the evaporation tray 102, with the bottom end of the feed box 20 spaced apart from the evaporation tray 102. A limiting thickness block 201 is fixedly connected to the bottom of the outer wall of the feed box 20. The limiting thickness block 201 extends radially from the evaporation tray 102, with the lowest point of the limiting thickness block 201 not higher than the lowest point of the feed box 20. The feed box 20 is provided with a feed channel extending vertically therethrough, with a valve installed at the bottom of the feed channel.

[0047] Specifically, the first driving member 103 is a motor, and the valve may be a gate valve.

[0048] It should be noted that the evaporation box 101 has a material extraction port with an interference fit of a blocking plate inside the material extraction port. After completing the soil testing, the staff can remove the blocking plate from the material extraction port, remove the soil from the surface of the evaporation plate, and clean the evaporation plate. After cleaning, the staff can then insert the blocking plate into the material extraction port.

[0049] Compared to the prior art, the composite contaminated soil treatment and detection device provided in this embodiment features a valve closed in the initial stage, during which soil to be tested is added to the material bin 20. After the soil is added, the valve is opened, allowing the soil to fall freely under gravity onto the surface of the evaporation tray 102. At this point, the first drive member 103 activates and drives the evaporation tray 102 to rotate, thereby spreading the soil across the surface of the evaporation tray 102. Simultaneously, the thickness limiting block 201 cooperates to form a uniform soil layer on the surface of the evaporation tray 102. This invention ensures uniform soil thickness across the surface of the evaporation tray 102, reducing errors and improving the accuracy of detection results.

[0050] In some embodiments, see Figure 2 、 Figure 3 and Figure 5 A feeding unit 30 is provided at the top of the material feeding channel, and the feeding unit 30 includes a material box 301, a feeding roller 302 and a second driving member 303. The material box 301 is connected to the top of the material feeding channel, and the material box 301 extends radially along the evaporation plate 102. A feeding port 3011 is provided at one end of the top wall of the material box 301, and a feeding port 3012 is provided at the bottom wall of the material box 301, and the feeding port 3012 extends along the length direction of the material box 301; the feeding roller 302 is rotatably connected to the material box 301, and a spiral feeding blade 3021 is provided on the outer periphery of the feeding roller 302; the second driving member 303 is transmission-connected to the feeding roller 302, and is used to drive the feeding roller 302 to rotate with the extension direction of the material box 301 as the rotation axis.

[0051] Specifically, the second driving member 303 is a motor.

[0052] The second driving member 303 starts to drive the distribution blade 3021 to rotate. The distribution blade 3021 pushes the soil forward during the rotation process. The soil forms an axial laminar flow movement inside the material box 301 and cooperates with the discharge port 3012 to allow the soil to enter the material box 20 evenly, thereby improving the uniformity of the soil in the material box 20, thereby improving the radial uniformity of the soil falling on the evaporation plate 102.

[0053] In some embodiments, see Figure 2 and Figure 4 The composite contaminated soil treatment and detection device also includes a material pressing unit 40, which includes a first telescopic member 401 and a blocking component. The first telescopic member 401 is fixed between the material box 301 and the material box 20, and the first telescopic member 401 is telescopic in the up and down directions; the blocking component is connected to the material box 301 and is used to block the discharge port 3012.

[0054] When the first telescopic member 401 is activated, the blocking component blocks the discharge port 3012 ; when the second driving member 303 is activated, the discharge port 3012 is in an open state.

[0055] Specifically, a storage cavity 3013 is opened on the inner wall of the discharge port 3012, and the blocking component is arranged in the storage cavity 3013. The blocking component includes a second telescopic member 402, a sealing plate 403 and a third telescopic member 404. The telescopic direction of the second telescopic member 402 is perpendicular to the extension direction of the discharge port 3012, and the fixed end of the second telescopic member 402 is fixedly connected to the inner wall of the storage cavity 3013; the plate surface of the sealing plate 403 is parallel to the horizontal direction; the third telescopic member 404 is telescopic in the up and down directions, the fixed end of the third telescopic member 404 is fixedly connected to the movable end of the second telescopic member 402, and the movable end of the third telescopic member 404 is fixedly connected to the top surface of the sealing plate 403.

[0056] Optionally, the second driving member 303 may be disposed in the material box 301 .

[0057] It should be noted that the first telescopic member 401 , the second telescopic member 402 and the third telescopic member 404 can all be telescopic oil cylinders, electric cylinders or hydraulic cylinders.

[0058] After adding soil to the hopper 20, the soil in the hopper 301 is completely used up. The valve is then opened, and the soil in the hopper 20 falls onto the surface of the evaporation tray 102. Before the valve is opened, the second telescopic member 402 drives the third telescopic member 404 and the sealing plate 403 to extend out of the storage chamber 3013. The third telescopic member 404 then activates and drives the sealing plate 403 downward until the bottom wall of the sealing plate 403 aligns with the bottom wall of the hopper 301. After the valve is opened, the first telescopic member 401 activates and drives the hopper 301 downward, causing the hopper 301 to push the soil in the hopper 20 downward, thereby accelerating the soil's fall and preventing it from sticking to the inner wall of the hopper 20. After all the soil in the hopper 20 has fallen onto the evaporation tray 102, the third telescopic member 404 activates and drives the sealing plate 403 upward. The second telescopic member 402 then activates and drives the third telescopic member 404 and the sealing plate 403 back into the storage chamber 3013.

[0059] In some embodiments, see Figure 4 A storage groove 3014 is provided on the inner wall of the storage cavity 3013, and the storage groove 3014 is opened in the up and down directions. A baffle 3015 is slidably connected in the storage groove 3014, and an elastic member 3016 is fixed between the inner wall of the storage groove 3014 and the baffle 3015. Extrusion surfaces are provided on both sides of the bottom of the baffle 3015.

[0060] Specifically, the elastic member 3016 can be a spring or a spring rod.

[0061] When the sealing plate 403 extends from the receiving chamber 3013, it presses against the inner extrusion surface of the baffle 3015, causing the baffle 3015 to be retracted into the receiving groove 3014. When the sealing plate 403 is retracted into the receiving chamber 3013, the outer extrusion surface of the baffle 3015 is continuously pressed, causing the baffle 3015 to be retracted into the receiving groove 3014. When the sealing plate 403 extends from or retracts into the receiving chamber 3013, the baffle 3015 remains within the receiving groove 3014. As soil enters the material bin 20 through the discharge port 3012, the baffle 3015 remains extended from the receiving groove 3014, reducing the possibility of soil entering the receiving chamber 3013 while passing through the discharge port 3012.

[0062] In some embodiments, see Figure 4 The sealing plate 403 abuts against the inner bottom wall of the storage cavity 3013 .

[0063] When the sealing plate 403 extends out of the receiving cavity 3013 , the sealing plate 403 pushes out all the soil in the receiving cavity 3013 , causing the soil to fall from the discharge port 3012 into the material box 20 , thereby avoiding insufficient soil samples in the future.

[0064] In some embodiments, see Figure 2 A hanger 202 is fixedly connected to the outer wall of the material box 20 , and the first telescopic member 401 is fixedly connected between the hanger 202 and the material box 301 .

[0065] If the first telescopic member 401 is placed on the inner wall of the material box 20, the material box 20 needs to be provided with a deeper material feeding channel, which will increase the difficulty of adding soil into the material box 301; placing the first telescopic member 401 above the material box 20 reduces the depth of the material feeding channel and reduces the difficulty of adding soil into the material box 301.

[0066] See also Figure 5 and Figure 6 Another variant implementation of the setting mode of the second driving member 303 is that a driving cavity 203 connected to the material feeding channel is opened in the box body of the material box 20, the second driving member 203 is arranged on the outer wall of the material box 20, and the output shaft of the second driving member 203 extends into the driving cavity 203, and a first through hole 204 connected to the driving cavity 203 is opened on the inner wall of the material box 20, and a second through hole 3017 corresponding to the first through hole 204 is opened through the material box 301, and a transmission hole 3022 aligned with the second through hole 3017 is opened on the end face of the cloth roller 302. A transmission unit 50 is provided in the drive cavity 203, and the transmission unit 50 includes a fourth telescopic member 501 and a transmission block 502. The fourth telescopic member 501 is telescopic along the axis of the cloth roller 302, and the fourth telescopic member 501 is fixedly connected to the output shaft of the second drive member 203; the transmission block 502 is fixedly connected to the telescopic end of the fourth telescopic member 501, and is plugged and adapted with the transmission hole 3022, so that the second drive member 303 drives the cloth roller 302 to rotate.

[0067] Specifically, the transmission hole 3022 includes a socket 3023 opened on the end face of the cloth roller 302 and a synchronization hole 3024 opened on the inner wall of the socket 3023; the transmission block 502 includes a plug block 5021 plugged and adapted to the socket 3023 and a synchronization block 5022 fixed to the outer wall of the plug block 5021, and the synchronization block 5022 is plugged and adapted to the synchronization hole 3024.

[0068] It should be noted that the fourth telescopic member 501 can be a telescopic oil cylinder, an electric cylinder, or a hydraulic cylinder; and the second driving member 303 is a motor.

[0069] When the soil in the material box 301 is added to the material box 20, the fourth telescopic member 501 extends to insert the transmission block 502 into the transmission hole 3022, thereby making the cloth roller 302 and the second driving member 303 rotate synchronously; when the soil is pushed down by the material box 301, the fourth telescopic member 501 is retracted to pull the transmission block 502 out of the transmission hole 3022, so that the cloth roller 302 and the second driving member 303 are separated.

[0070] Another embodiment of the transmission hole 3022 and the transmission block 502 is that the transmission hole 3022 is a square hole and the inserting block 5021 is a square block.

[0071] In some embodiments, see Figure 1 A ball bearing 1021 is installed on the outer periphery of the evaporation plate 102, and the ball bearing 1021 abuts against the inner wall of the evaporation box 101; a baffle ring 1022 is fixed to the top surface of the evaporation plate 102, and the baffle ring 1022 is coaxial with the evaporation plate 102, and the thickness limiting block 201 is arranged in the baffle ring 1022.

[0072] The balls 1021 reduce the friction between the evaporation tray 102 and the inner wall of the evaporation box 101, thereby improving the smoothness of rotation of the evaporation tray 102; the retaining ring 1022 intercepts the soil so that it does not fall from the evaporation tray 102, thereby avoiding insufficient soil samples.

[0073] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
