Description

Technical Field

[0001] The present invention relates to the technical field of slag detection, and specifically to a device for detecting the urban ecological environment. Background Art

[0002] The detection of industrial solid waste is a common and important direction in the detection of the urban ecological environment. Most cities (especially industrial cities) have industries such as metallurgy, chemical engineering, and energy, generating a large amount of industrial solid waste residues such as smelting slag, fly ash, and furnace slag. Industrial solid waste residues may contain heavy metals (such as nickel and chromium) and sometimes may also contain radioactive elements. Therefore, it is necessary to detect industrial solid waste residues to judge environmental risks.

[0003] Currently, industrial solid slag is usually stored in a piled form. Generally, it is necessary to take multiple layers of samples from the slag and detect the obtained samples to determine the metal element components contained in the industrial solid slag. Currently, for small slag piles, manual sampling tools such as shovels, sampling tubes, or probes are usually used for sampling.

[0004] The following problems exist in the above sampling process: First, in the sampling process, it is necessary to take multiple layers of samples from the slag at different positions. The specific process of taking multiple layers of samples at different heights is to repeat the sampling multiple times. Take a slag sample at one height each time to obtain slag samples at different heights. The sampling operation efficiency is not good.

[0005] Secondly, when using a sampling tube for sampling, it is difficult for the slag to enter the sampling tube due to caking between the slag.

[0006] And in the above sampling process, some samples remain in the sampling tube, so it is easy to mix with the slag obtained from subsequent sampling again, affecting the test results. Summary of the Invention

[0007] Based on this, it is necessary to provide a device for detecting the urban ecological environment, aiming to solve the problems of the above-mentioned existing technologies.

Detailed Embodiment

[0039] To make the above objects, features and advantages of the present invention more obvious and understandable, the following detailed description of the specific embodiments of the present invention will be made in conjunction with the drawings. Many specific details are set forth in the following description in order to fully understand the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0040] As Figure 1 and Figure 2 shown, an urban ecological environment detection device includes: a sampling cylinder 1, the sampling cylinder 1 is successively divided into a plurality of equally spaced sampling sections 10 from top to bottom and a sampling tip 11 for facilitating the insertion of the sampling cylinder 1 into a sample, and a sampling mechanism 2 is arranged in the sampling section 10.

[0041] As Figure 1 , Figure 2 and Figure 10As shown, the sampling mechanism 2 includes a sampling cavity 20, a sampling cavity 20 is opened in the sampling section 10 of the sampling tube 1, a sampling port 21 connected to the sampling cavity 20 is opened on the sampling tube 1, and an opening and closing arc piece 22 is circumferentially rotated in the sampling cavity 20. The opening and closing arc piece 22 is spliced by a No. 1 arc piece 220 and a No. 2 arc piece 221, wherein the height of the No. 1 arc piece 220 is the same as the height of the sampling cavity 20, and the height of the No. 2 arc piece 221 is half the height of the sampling cavity 20.

[0042] like Figure 1 and Figure 2 As shown, the upper end of the sampling tube 1 is provided with an operating rod 23 with a vertical axis. The operating rod 23 controls the rotation angle of all the opening and closing arc pieces 22 in the sampling mechanism 2, so that the sampling port 21 switches between three states: fully closed, semi-closed and fully open. The state switching process is shown in FIG. Figure 12 .

[0043] like Figure 1 、 Figure 3 、 Figure 6 and Figure 8 As shown, the sampling chamber 20 is composed of a cylindrical section 200 and a conical section 201 from top to bottom. The sampling mechanism 2 also includes a cleaning portion 24 arranged in the sampling chamber 20. The cleaning portion 24 includes a cleaning cone 240 for cleaning the inner wall of the opening and closing arc piece 22 and cleaning excess samples into the conical section 201 of the sampling chamber 20, and a scraper 241 for cleaning the sampling chamber 20.

[0044] like Figure 1 and Figure 8 As shown, the sampling cavity 20 is provided with a material-moving portion 25 for assisting the sample to enter the sampling cavity 20 by moving the sample.

[0045] See Figure 12During operation, the operator first manually controls the opening and closing arc piece 22 to rotate through the operating rod 23, so that the No. 1 arc piece 220 in the opening and closing arc piece 22 is opposite to the sampling port 21, so that the sampling cavity 20 is in a completely closed state at this time. Then, the sampling tube 1 is manually inserted into the slag sample, and the operating rod 23 is manually rotated to control the opening and closing arc piece 22 to rotate a specified angle, so that the No. 1 arc piece 220 in the opening and closing arc piece 22 is staggered with the sampling port 21, and the No. 2 arc piece 221 is opposite to the sampling port 21. At this time, the sampling port 21 is in a semi-closed state, and the slag sample enters the sampling cavity 20 from the sampling port 21. Then, the operator manually moves the operating rod 23 up and down, so that the cleaning cone 240 moves up and down. Move, during this process, the material-prying part 25 assists the slag sample to enter the sampling cavity 20, and at the same time presses the slag sample in the sampling cavity 20 to increase the sampling capacity. After completing the sampling operation, the operating lever 23 is manually rotated to make the No. 1 arc piece 220 face the sampling port 21 again, and the sampling cavity 20 is restored to a fully closed state. At this time, the slag sample of the required height is in the corresponding sampling cavity 20, and the sampling tube 1 is manually removed. Then, by rotating the operating lever 23, the opening and closing arc piece 22 is staggered with the sampling port 21, that is, the sampling cavity 20 is in a fully open state at this time, and all the slag samples in the sampling cavity 20 are poured out, so that slag samples of different heights are obtained.

[0046] After completing the material collection operation, the operating rod 23 is manually rotated throughout the circle to make the opening and closing arc piece 22 rotate throughout the circle, and the scraper 241 cleans the inner wall of the sampling chamber 20, and the operating rod 23 is moved up and down to make the cleaning cone 240 clean the inner wall of the opening and closing arc piece 22, and the excess slag sample generated is discharged from the sampling tube 1 after passing through the conical section 201 of the sampling chamber 20, so as to avoid the problem of the remaining slag sample mixing with the slag sample in the subsequent sampling process and affecting the accuracy of the test results. It should be noted that the parts of the sampling tube 1 that are easy to clean, such as the sampling port 21, are cleaned manually.

[0047] like Figure 1 、 Figure 2 and Figure 4 As shown, a connecting rod 230 is movably provided on the sampling section 10 of the sampling barrel 1, and the connecting rod 230 passes through the corresponding sampling cavity 20. The cleaning cone 240 is fixedly provided on the lower end surface of the connecting rod 230 that passes through the corresponding sampling cavity 20. The two adjacent connecting rods 230 are fixedly connected by an L-shaped connecting frame 231. The connecting frame 231 is rotatably provided in the sampling barrel 1, and the uppermost connecting frame 231 is fixedly connected to the operating rod 23.

[0048] To facilitate manual control of the sampling process within all sampling sections 10 by operating the operating rod 23, a connecting frame 231 is provided to connect two adjacent connecting rods 230. Thus, the operating rod 23 can not only drive all the connecting rods 230 to move up and down through the connecting frame 231, but also drive the connecting rods 230 to rotate synchronously. It should be additionally noted that a placement cavity is provided on the sampling section 10 of the sampling cylinder 1 above the sampling cavity 20. The connecting frame 231 is disposed within the placement cavity, and the vertical section of the connecting frame 231 slides up and down through the connecting sections of two adjacent sampling cylinders 1. Secondly, the horizontal cross-section of the placement cavity is a sector with an angle exceeding 180 degrees. Therefore, the connecting frame 231 rotates by an angle exceeding 180 degrees, that is, the rotating angle of the closing arc piece exceeds 180 degrees.

[0049] As Figure 1 and Figure 2 shown, to facilitate manual operation, an auxiliary handle 26 is fixedly provided on the upper end face of the sampling cylinder 1, and an operating handle 260 is fixedly provided on the upper end face of the operating rod 23. An operator can insert the sampling cylinder 1 into the slag sample by pressing down on the auxiliary handle 26. Secondly, an operator can operate the operating rod 23 by moving or rotating the operating handle 260. In summary, to improve the convenience during the sampling process, two reference members 261 that are circumferentially distributed and used to align the rotation angle are fixedly provided on the upper end face of the sampling cylinder 1. When the operating handle 260 is vertically aligned with the auxiliary handle 26 and the two reference members 261 respectively, they correspond to the three operating states of the sampling port 21. Refer to Figure 12 .

[0050] When the auxiliary handle 26 and the operating handle 260 are vertically opposite, they not only serve as the docking reference for the insertion rod 235 and the insertion slot 234, but also correspond to the fully closed state of the sampling port 21. When the operating handle 260 rotates to be vertically opposite the first reference member 261, it corresponds to the semi-closed state of the sampling port 21. When the operating handle 260 rotates to be vertically opposite the other reference member 261, it corresponds to the fully open state of the sampling port 21. In summary, by rotating the operating handle 260 to different positions, the opening and closing state of the sampling port 21 can be controlled, and during each state of the sampling port 21, the process of inserting the sampling cylinder 1 into the slag sample, the sampling process of the sampling cylinder 1, and the material taking process after removing the sampling cylinder 1 can be carried out.

[0051] As Figure 8 and Figure 11As shown, a curved barrier strip 232 is fixedly arranged on the upper end surface of the first arc-shaped piece 220. In order to prevent slag sample from entering the upper side area of the cleaning cone 240 during the sampling process, the vertical projection of the barrier strip 232 and the vertical projection of the first arc-shaped piece 220 form a complete circle. Therefore, the barrier strip 232 and the first arc-shaped piece 220 form a partition area for sealing the upper side area of the cleaning cone 240, avoiding the problem that slag sample remains in the sampling cavity 20 and affects the subsequent slag sample. An L-shaped bracket 233 is fixedly arranged on the upper end surface of the first arc-shaped piece 220. A driving sleeve is fixedly sleeved on the L-shaped bracket 233. The driving sleeve is movably sleeved on the corresponding connecting rod 230. Two insertion slots 234 are arranged on the lower end surface of the driving sleeve. The lower end of the inner wall of the insertion slot 234 is chamfered. The upper end surface of the cleaning cone 240 is fixedly provided with insertion rods 235 corresponding to the insertion slots 234 one by one. When the cleaning cone 240 contacts the barrier strip 232, the insertion rods 235 are inserted into the insertion slots 234, and the operating rod 23 and the connecting rod 230 can drive the opening and closing arc piece 22 to rotate circumferentially.

[0052] Manually rotate the operating handle 260 so that the operating handle 260 and the auxiliary handle 26 are vertically aligned. At this time, the insertion rod 235 is located directly below the corresponding insertion slot 234. Move the operating handle 260 and the operating rod 23 upward. When the operating handle 260 moves to the highest point, the insertion rod 235 moves into the corresponding insertion slot 234. At this time, the connecting rod 230, the corresponding driving sleeve and the opening and closing arc piece 22 form a whole in the circumferential direction. Therefore, when the operating rod 23 is manually rotated, all the opening and closing arc pieces 22 rotate synchronously, so that the opening and closing states of each sampling port 21 can be controlled. Secondly, when the cleaning cone 240 needs to move up and down for cleaning, all the connecting rods 230 move up and down by manually moving the operating rod 23 up and down.

[0053] As Figure 8 and Figure 11 shown, the number of scraping blades 241 in the same sampling cavity 20 is three, and they are respectively fixedly arranged on two side surfaces of the first arc-shaped piece 220 and the side surface of the second arc-shaped piece 221. As Figure 5 、 Figure 6 and Figure 7 shown, a sealing plate 27 is slidably arranged back and forth on the rear side of the sampling cylinder 1 through a horizontal rod. A return spring 270 sleeved on the horizontal rod is fixedly arranged between the sealing plate 27 and the sampling cylinder 1. The cleaning part 24 further includes a through groove 271. Through grooves 271 communicating with the outside are all formed through the sampling cylinder 1 of the sampling cylinder 1. A partition plate 272 corresponding to the through groove 271 is fixedly arranged on the inner arc surface of the sealing plate 27. The partition plate 272 divides the cylindrical section 200 and the conical section 201 of the sampling cavity 20. A discharge groove 273 communicating with the conical section 201 of the sampling cavity 20 is formed on the sampling cylinder 1. When the sealing plate 27 fits the sampling cylinder 1, all the discharge grooves 273 are sealed.

[0054] After pouring out the taken slag sample, the operator first rotates the operating handle 260 manually, so that the operating rod 23 drives all the connecting rods 230 and the opening and closing arc pieces 22 to rotate reciprocally. Therefore, the scraping blade 241 on the first arc piece 220 rotates more than 180 degrees in the first stroke, and the other scraping blade 241 on the first arc piece 220 and the scraping blade 241 on the second arc piece 221 rotate 180 degrees in the return stroke. Therefore, all the scraping blades 241 cover the entire circumferential inner wall of the sampling cavity 20 in a reciprocating rotation cycle, that is, the circumferential inner wall of the sampling cavity 20 is scraped and cleaned, avoiding the problem that the slag sample adheres to the inner wall of the sampling cavity 20 and affects the subsequent sampling process again.

[0055] When cleaning the inner wall of the cleaning cavity as described above, some of the slag samples scraped and cleaned and some of the slag samples remaining in the sampling cavity 20 (slag samples remaining due to incomplete pouring) stay at the bottom of the cylindrical section 200 of the sampling cavity 20. The operator moves the sealing plate 27 manually, so that the return spring 270 is stretched, and the sealing of the discharge chute 273 by the sealing plate 27 is released. At the same time, the sealing plate 27 drives the partition plate 272 to move out of the corresponding through groove 2 / / 71. After the above slag samples fall into the conical section 201 of the sampling cavity 20, they are discharged through the discharge chute 273. Secondly, in the above process, the operator moves the operating handle downward, so that the operating rod 23 drives the connecting rod 230 and the cleaning cone 240 to move downward synchronously. During the downward movement of the cleaning cone 240, the excess slag samples adhered to the inner wall of the opening and closing arc piece 22 are extruded, and finally the slag samples enter the conical section 201 of the sampling cavity 20, that is, the cleaning cone 240 cleans the inner arc surface of the opening and closing arc piece 22 and the conical section 201 of the sampling cavity 20, thereby assisting the excess slag samples to be discharged through the discharge chute 273. After completing the above operations, the sealing plate 27 and the partition plate 272 are reset by the elastic force generated by the return spring 270. By separating the cylindrical section 200 and the conical section 201 of the sampling cavity 20 by the partition plate 272, no matter whether the excess slag samples are fully discharged or not, the partition function of the partition plate 272 ensures that there is no residual slag sample in the sampling cavity 20. Secondly, the sealing plate 27 seals the discharge chute 273. In summary, it is avoided that the slag sample obtained in the re-sampling operation contacts the slag sample remaining in the previous sampling process, resulting in affecting the test results.

[0056] Such as Figure 8 and Figure 9As shown in the figure, the material feeding part 25 includes a mounting plate 250. The lower end surface of the barrier strip 232 is fixedly provided with a mounting plate 250. The mounting plate 250 is located directly above the second arc-shaped piece 221. A receiving groove is formed in the mounting plate 250. A rotating column 251 is rotatably arranged on the mounting plate 250 and passes through the receiving groove with a horizontal axis. Material feeding plates 252 are fixedly sleeved on both ends of the rotating column 251. The material feeding part 25 further includes a driving group for driving the material feeding plate 252 to unfold from the vertical state.

[0057] As Figure 9 shown, a plurality of equally spaced material scraping strips 253 are fixedly arranged on the lower end surface of the material feeding plate 252. The material scraping strips 253 are diamond-shaped and their tips face the axis of the sampling cylinder 1 at the initial time.

[0058] As Figure 8 、 Figure 9 and Figure 11 shown, the driving group includes a volute spring 254. A volute spring 254 is fixedly arranged between the rotating column 251 and the inner wall of the receiving groove. A pressing ring 255 is fixedly sleeved on the cleaning cone 240. It should be noted that in order to prevent the cleaning cone 240 from coinciding with the conical section 201 of the sampling cavity 20 after moving downward, the provided pressing ring 255 is located on the upper side section of the cleaning cone 240 and is made of rubber. The upper side of the end surface of the material scraping strip 253 facing away from the axis of the sampling cylinder 1 is inclined outward from top to bottom. Guide grooves 256 corresponding to the material scraping strips 253 are formed on the inner walls on both sides of the sampling port 21.

[0059] It should be noted that after the sampling cylinder 1 is inserted into the slag sample, at this time the sampling port 21 is still in a completely closed state. At this time, the volute spring 254 is in a deformed state. The elastic force generated by the deformation of the volute spring 254 makes the lower end of the material feeding plate 252 tend to rotate upward. Then, the operator rotates the operating rod 23 manually to make the opening and closing arc piece 22 rotate and take materials. And in this state, the mounting plate 250, the material feeding plate 252 and the material scraping strips 253 are all directly above the second arc-shaped piece 221. At this time, the cleaning cone 240 and the material feeding plate 252 are staggered in the up and down direction. The material feeding plate 252 will not contact the pressing ring 255 during the up and down movement of the cleaning cone 240.

[0060] As the opening and closing arc piece 22 continues to rotate to make the sampling port 21 in a semi-closed state, part of the slag sample enters the sampling cavity 20 through the sampling port 21. At this time, the mounting plate 250 rotates to face the sampling port 21. As the elastic force generated by the deformation of the scroll spring 254 causes the lower end of the material deflecting plate 252 to rotate upward by a set angle. At this time, the vertical upward projection of the upper end of the material deflecting plate 252 is located inside the pressing ring 255. That is, during the downward movement of the cleaning cone 240, the pressing ring 255 can contact the upper end of the material deflecting plate 252. In order to make the sampling amount reach the required sampling amount, the operator manually moves the operating rod 23 downward, so that the operating rod 23 drives the cleaning cone 240 to move downward through the connecting rod 230. During the process of the cleaning cone 240 driving the pressing ring 255 to move downward, the pressing ring 255 presses the material deflecting plate 252 and makes the lower end face of the material deflecting plate 252 continue to rotate upward. During this process, it should be noted that although the pressing ring 255 is made of rubber, after the pressing ring 255 presses the material deflecting plate 252, the material deflecting plate 252 is located between the pressing ring 255 and the cleaning cone 240. From the fact that the pressing ring 255 can make the material deflecting plate 252 rotate by pressing the material deflecting plate 252. During the rotation of the material deflecting plate 252, the material deflecting plate 252 stirs the slag sample around the sampling cylinder 1, and at the same time, the edge of the material scraping strip 253 scrapes the slag sample around the sampling port 21, assisting the slag sample to flow into the sampling port 21, avoiding the problem that the agglomeration between the slag samples affects the sampling process, and during the up and down movement of the cleaning cone 240, the cleaning cone 240 presses the slag sample that has already entered the sampling cavity 20, creating the required space for the slag sample that will enter the sampling cavity 20 later. In summary, it assists the sampling cavity 20 to obtain a sufficient amount of slag sample.

[0061] After the sampling is completed, the operating rod 23 moves upward, the material deflecting plate 252 resets, and the operating rod 23 is rotated. The material deflecting plate 252 cooperates with the guiding groove 256, and the inner wall of the guiding groove 256 squeezes the lower part of the material deflecting plate 252, thereby guiding the material deflecting plate 252 to return to the initial state and re-enter the sampling cavity 20. Finally, the obtained multi-layer sufficient slag samples are detected. Among them, whether the slag contains harmful heavy metal substances is detected by various sensors of existing heavy metal content detection instruments. Specifically, the sensors that may be used include electrochemical sensors, photoelectric sensors, ion sensors, etc.; and whether the slag contains radioactive substances is detected by various radiation sensors of existing radioactive detectors.
