Description

Technical Field

[0001] The present application relates to the technical field of municipal sewage detection, and in particular to a municipal sewage sludge concentration detection system and detection method. Background Art

[0002] With the acceleration of urbanization, municipal sewage treatment has become an important part of environmental protection. The large amount of sludge generated during sewage treatment has a concentration that directly affects the subsequent treatment efficiency and cost. In order to improve the comprehensive management and comprehensive utilization of municipal sewage sludge and maintain a good ecological environment, it is particularly important to detect the concentration of municipal sewage sludge. Most of the existing sludge concentration detection technologies rely on manual sampling and laboratory testing. This method is not only time-consuming and laborious, but also difficult to monitor in real time and cannot fully reflect the operating status of the entire sewage treatment system.

[0003] The existing Chinese utility model patent document with authorization announcement number CN216284824U discloses a municipal sewage sludge concentration detection system, including a sewage pool main body, a slider is connected to the side wall of the sewage pool main body for sliding up and down, and a detection head is installed on the slider. The detection head is connected to the display screen through a connecting line. The sewage can be detected through the detection head, and the rise and fall of the slider driven by the winding box can also be used for detection at different depths.

[0004] In this technical solution, although the detection head can move up and down to detect positions at different depths, its detection range is limited and it cannot detect other different positions in the sewage pool body. The accuracy of the detection results still needs to be improved. Summary of the invention

[0005] In a first aspect, in order to better detect different points to improve the accuracy of detection data, the present application provides a municipal sewage sludge concentration detection system.

[0006] The present application adopts the following technical scheme: a municipal sewage sludge concentration detection system, comprising a tank body, a detector, a detection head and a connecting line connected between the detector and the detection head; and also comprising an adjustment component arranged in the tank body, wherein an upwardly extending column is arranged at the center of the tank body, and a rotating plate is rotatably connected to the upper end of the column, and the end of the rotating plate away from the column abuts against the upper end of the tank body, and the detector is connected to the end of the rotating plate away from the column; the adjustment component comprises a sliding plate slidably connected to the rotating plate, and an adjustment plate slidably arranged on the sliding plate up and down, the rotating plate is provided with a first element for driving the sliding plate to slide along the length direction of the rotating plate, the sliding plate is provided with a second element for driving the adjustment plate to slide up and down on the sliding plate, a winding wheel is arranged on the sliding plate, the connecting line is wound on the winding wheel and the detection head is connected to the lower end of the adjustment plate; an engagement bar is arranged on the adjustment plate, and the engagement bar cooperates with the winding wheel so that the winding wheel is driven to rotate synchronously when the adjustment plate moves up and down.

[0007] By adopting the above technical solution, the rotating plate can rotate in the pool body, thereby driving the detection head to move to different positions in the pool body, and by adjusting the position of the sliding plate, the detection head can correspond to a larger range, and by adjusting the vertical position of the adjustment plate, the detection head can correspond to different depths. Therefore, under the synergistic effect of the rotating plate, the sliding plate and the adjustment plate, the position that the detection head can detect can be greatly increased, so that more data at different positions can be collected, making the data more accurate and referenceable.

[0008] Optionally, a fixed cylinder with a hollow interior is provided at the lower end of the adjustment plate, and through slots are provided at intervals on the side walls of the fixed cylinder, the detection head is located in the fixed cylinder, and the connecting line passes through the fixed cylinder and is connected to the detection head; an adjustment cylinder is rotatably provided on the outer wall of the fixed cylinder, a clearance groove is provided on the side wall of the adjustment cylinder, and a through hole is provided at the end of the adjustment cylinder for the connecting line to pass through; a third element is provided in the adjustment plate for driving the engaging strip to slide horizontally in the adjustment plate, the engaging strip and the adjusting cylinder are linked to each other, and when the engaging strip and the winding wheel cooperate, the clearance groove and the through slot coincide with each other, and when the engaging strip and the winding wheel lose contact, the clearance groove and the through slot are staggered.

[0009] By adopting the above technical solution, the detection head is located in the fixed cylinder. When the meshing strip and the winding wheel are matched, the clearance groove and the through groove overlap, so when the adjustment plate moves up and down, the sewage in the fixed cylinder can flow in or out. After the fixed cylinder moves to the specified detection position, the meshing strip and the winding wheel are driven to disengage through the third element, and the clearance groove and the through groove are staggered, that is, the adjustment cylinder can be closed in the through groove, and the detection head performs detection in the fixed cylinder, and the detection result will not be affected by the flow of sewage, thereby improving the detection accuracy. When the adjustment plate moves upward, the meshing strip needs to be matched with the winding wheel again, so the through groove and the clearance groove overlap, and the movement of the fixed cylinder can make the sewage in the fixed cylinder flow out.

[0010] Optionally, the winding wheel includes a rotating shaft and a turntable arranged at both ends of the rotating shaft, a base is arranged on the sliding plate, and the turntable is rotatably connected to the base; teeth are arranged on the side wall of the turntable, the engaging strip and the turntable correspond one by one, and teeth are arranged on the side of the engaging strip close to the turntable so that the engaging strip and the turntable can engage with each other.

[0011] By adopting the above technical solution, the engagement bar and the turntable are engaged, so when the adjustment plate moves up and down, the turntable can be driven to rotate, and the connecting line can be stored or released.

Therefore, when the third element is reset, the elastic member can drive the engaging strip to reset, so that the engaging strip and the turntable can be re-matched.

[0014] Optionally, an extension column extending downward is provided at the lower end of the engagement bar, and a linkage groove is opened at the upper end of the adjustment cylinder. The linkage groove is inclined and the extension column extends into the linkage groove, so that the adjustment cylinder is driven to rotate when the engagement bar moves.

[0015] By adopting the above technical solution, the extension column extends in the linkage groove, so when the engagement bar moves, the adjustment cylinder is pushed to rotate by the extension column, thereby achieving the staggering or overlapping of the clearance groove and the through groove.

[0016] Optionally, the third element includes a rotating rod rotatably arranged in the adjustment plate and a power source for driving the rotating rod to rotate, and a resistance block is arranged on the side wall of the rotating rod, and the resistance block and the rotating rod are eccentrically arranged. When the rotating rod rotates, the resistance block can abut against the connecting plate and push the connecting plate to move.

[0017] By adopting the above technical solution, the abutment block abuts against the connecting plate and pushes the connecting plate to move, thereby achieving the effect of adjusting the position of the meshing strip.

[0018] Optionally, a positioning member for positioning the turntable is installed on the base, and the positioning member cooperates with the engaging bar. When the engaging bar and the turntable are engaged, the positioning of the turntable by the positioning member can be released. When the engaging bar and the turntable are separated, the positioning member can position the turntable to limit the rotation of the turntable.

[0019] By adopting the above technical solution, when the engagement strip and the turntable are out of contact, the positioning member positions the turntable so that the turntable is not likely to rotate, and thus the wound connecting wire is not likely to fall off or become loose.

[0020] Optionally, the positioning member includes an extension tube horizontally arranged on the base, a sliding column slidably arranged in the extension tube and a reset member arranged in the extension tube; an annular groove is provided on the side wall of the turntable, and the inner wall of the annular groove is a rough structure, and a positioning block is provided on the side wall of the sliding column, and the positioning block abuts against the inner wall of the annular groove under the action of the reset member; a resistance bar is provided on the side wall of the engaging bar, and when the elastic member drives the engaging bar and the turntable to engage, the resistance bar abuts against the end of the sliding column and pushes the sliding column to slide into the extension tube, and the positioning block and the inner wall of the annular groove are out of contact.

[0021] By adopting the above technical solution, when the resistance bar pushes the sliding column to slide into the extension tube, the resistance block and the inner wall of the annular groove are separated, so the rotation of the turntable is not affected; when the resistance block abuts against the inner wall of the annular groove, the resistance block can limit the rotation of the turntable.

[0022] Optionally, a slot is provided on the rotating plate, the sliding plate slides in the slot, a guide slot is provided on an inner wall of the slot, and a guide block extending into the guide slot is provided on a side wall of the sliding plate.

[0027] (2) When continuing to detect the next point, the second element drives the adjustment plate to slide upward, so that the detection head comes out of the sewage, and then drives the rotating plate to rotate. The position of the sliding plate is adjusted by the first element, and then the detection head is driven into the sewage for detection by the second element.

[0028] In summary, the present application includes at least one of the following beneficial effects:

The detection head 3 penetrates into the sewage to detect the sewage, and reads the detection data through the detector 2. The detection principle is a prior art and is not the focus of this application, so it will not be described in detail here.

[0045] The detection system also includes an adjustment component 5, through which the position of the detection head 3 can be adjusted, so as to detect different positions in the pool body 1. The pool body 1 is a cylindrical structure, and a column 6 extending upward is coaxially fixed at the center of the pool body 1. A rotating plate 7 is rotatably installed on the upper end of the column 6.

[0046] Reference Figure 2 and Figure 3 The adjusting assembly 5 includes a sliding plate 51 slidably mounted on the rotating plate 7, and an adjusting plate 52 sliding up and down on the sliding plate 51. The sliding plate 51 slides along the length direction of the rotating plate 7, and a first element 8 for driving the sliding plate 51 to slide is installed on the rotating plate 7. The adjusting plate 52 vertically slides through the sliding plate 51, and a second element 9 for driving the adjusting plate 52 to move up and down is installed on the sliding plate 51. The detector 2 is fixed to the end of the rotating plate 7 away from the column 6, and a winding wheel 10 is also installed on the sliding plate 51. The middle position of the connecting line 4 is fixed to the winding wheel 10, and the connecting line 4 has a sufficient length between the detector 2 and the winding wheel 10, so that the winding wheel 10 can receive the connecting line 4 of this part. The detection head 3 is installed at the lower end of the adjusting plate 52, and the connecting line 4 passes through the sliding plate 51 and is connected to the detection head 3. Therefore, by adjusting the positions of the rotating plate 7, the sliding plate 51 and the adjusting plate 52, different positions in the pool body 1 can be detected.

A guide slot 27 is provided on the inner wall of the slot 26, and a guide block 28 is symmetrically fixed on the side wall of the sliding plate 51, and the guide block 28 extends in the guide slot 27, so that the sliding plate 51 is not easy to be separated from the slot 26. The first element 8 is a multi-section cylinder or a multi-section telescopic cylinder, and the first element 8 is fixed to the end surface of the rotating plate 7 close to the column 6, and the piston rod is connected to the sliding plate 51, so as to facilitate the sliding plate 51 to slide on the rotating plate 7. The second element 9 is a multi-section cylinder or a multi-section telescopic cylinder, and the second element 9 is fixed to the lower surface of the sliding plate 51, and the piston rod of the second element 9 passes through the sliding plate 51 and is connected to the adjusting plate 52, so as to achieve the effect of pushing the adjusting plate 52 to move up and down.

[0048] Reference Figure 4The winding wheel 10 includes a rotating shaft 101 and a rotating disk 102 coaxially fixed at both ends of the rotating shaft 101, and the connecting line 4 is fixed to the side wall of the rotating shaft 101 by means of buckles, screws, etc. Two bases 18 are fixed on the upper surface of the sliding plate 51, and the winding wheel 10 is located between the two bases 18. The base 18 is provided with a rotating shaft that is rotatably plugged into the center of the rotating disk 102, so as to realize the rotation installation of the winding wheel 10. A meshing bar 11 is installed on the side of the adjusting plate 52 facing the winding wheel 10, and two meshing bars 11 are provided and correspond to the rotating disk 102. The meshing bar 11 is vertically arranged, and a hole groove is provided at the position corresponding to the meshing bar 11 on the sliding plate 51, so that the meshing bar 11 can move up and down synchronously when the adjusting plate 52 moves up and down. The side wall of the rotating disk 102 is evenly provided with teeth, and the meshing bar 11 is also provided with teeth on the side facing the rotating disk 102, and the meshing bar 11 and the rotating disk 102 are meshed with each other. When the adjusting plate 52 moves up and down, it can synchronously drive the turntable 102 to rotate, thereby storing or releasing the connecting line 4.

[0049] In a further embodiment, referring to Figure 3 and Figure 5 A fixed cylinder 12 is fixed to the lower end of the adjustment plate 52, and a through groove 13 is provided on the side wall of the fixed cylinder 12. A plurality of through grooves 13 are distributed at intervals along the circumference of the fixed cylinder 12. The detection head 3 is installed in the inner top surface of the fixed cylinder 12, and the connecting line 4 passes through the upper end of the fixed cylinder 12 and extends into the fixed cylinder 12 to connect with the detection head 3. A cylindrical portion 29 is fixed to the lower end of the adjustment plate 52, and the fixed cylinder 12 is fixed to the lower end of the cylindrical portion 29. An adjustment cylinder 15 is rotatably installed on the outer wall of the fixed cylinder 12, and the upper end of the adjustment cylinder 15 is rotatably connected to the outer wall of the cylindrical portion 29. Combined with Figure 6 , the adjusting cylinder 15 is provided with a clearance groove 16, the number of which is the same as the through groove 13, and when the adjusting cylinder 15 rotates, the clearance groove 16 and the through groove 13 can be overlapped or staggered, and when the two are staggered, the adjusting cylinder 15 is closed in the through groove 13. And the upper end of the adjusting cylinder 15 is provided with a through hole 14, and the connecting line 4 is passed through the through hole 14, so that the connecting line 4 does not affect the rotation of the adjusting cylinder 15. When the position of the detection head 3 is adjusted, the clearance groove 16 and the through groove 13 are overlapped, so the sewage in the fixed cylinder 12 can flow in and out. When the detection is performed, the adjusting cylinder 15 rotates, so that the clearance groove 16 and the through groove 13 are staggered, so that the sewage will no longer flow into the fixed cylinder 12, thereby reducing the error of the detection caused by the flow of sewage.

[0050] Reference Figure 3 and Figure 6, the meshing strip 11 is horizontally slidably installed in the adjustment plate 52, and the adjustment plate 52 is installed with a third element 17 for driving the meshing strip 11 to slide. The lower end of the meshing strip 11 is linked with the adjustment cylinder 15. When the meshing strip 11 and the winding wheel 10 are matched, the clearance groove 16 and the through groove 13 overlap. At this time, the movement of the adjustment plate 52 can make the sewage in the fixed cylinder 12 flow out and flow into the sewage in the new position. When the ideal position is reached, the third element 17 drives the meshing strip 11 to slide, the meshing strip 11 and the rotating disk 102 are out of contact, and the clearance groove 16 and the through groove 13 are staggered.

[0051] Reference Figure 7 and Figure 8 , an accommodating cavity 19 is provided inside the adjusting plate 52, and two engaging strips 11 are slidably provided through the side wall of the adjusting plate 52 and extend into the accommodating cavity 19. The two engaging strips 11 are fixed to the same connecting plate 20 on one side of the accommodating cavity 19. The third element 17 extends into the accommodating cavity 19 and is located on the side of the connecting plate 20 close to the winding wheel 10. An elastic member 21 is installed on the side of the connecting plate 20 facing away from the winding wheel 10. The elastic member 21 is a spring and a plurality of them may be fixed. The spring is connected between the connecting plate 20 and the inner wall of the accommodating cavity 19. The third element 17 drives the connecting plate 20 to move, and when the engaging strip 11 and the turntable 102 are separated, the elastic member 21 is in a compressed state.

[0052] Combination Figure 6 The upper end surface of the adjusting cylinder 15 is provided with a linkage groove 23, which is inclined. An extension column 22 extending downward is fixed to the lower end of one of the engagement bars 11, and the extension column 22 extends into the linkage groove 23. When the engagement bar 11 moves, the adjusting cylinder 15 can be driven to rotate through the extension column 22.

[0053] Reference Figure 8 and Fig. 9 The third element 17 includes a rotating rod 171 vertically connected to the adjustment plate 52 and a power source 172 for driving the rotating rod 171 to rotate. The power source 172 can be a motor or a rotary cylinder or other device. A resistance block 173 is fixed to the side wall of the rotating rod 171 in the accommodating chamber 19. The resistance block 173 can be an arc-shaped block. When the rotating rod 171 rotates, the resistance block 173 can abut against the connecting plate 20 and push the connecting plate 20 to slide, and the elastic member 21 is compressed, thereby driving the rotation of the rotating cylinder. When the resistance block 173 and the connecting plate 20 are out of contact, the elastic member 21 drives the connecting plate 20 to reset.

[0054] In a further embodiment, referring to Figure 7 and Fig.10A positioning member 24 for positioning the turntable 102 is installed on the base 18. The positioning member 24 is linked to the engagement bar 11. When the engagement bar 11 is engaged with the turntable 102, the positioning member 24 can release the positioning of the turntable 102, so that the up and down movement of the engagement bar 11 can synchronously drive the turntable 102 to rotate, so as to achieve the effect of winding and releasing the line. When the engagement bar 11 and the turntable 102 are separated, the positioning member 24 positions the turntable 102, reducing the turntable 102 from rotating spontaneously and causing the connecting line 4 to fall into the pool body 1.

[0055] Reference Figure 7 and Fig.11 The positioning member 24 includes an extension tube 241 horizontally fixed on the base 18, a sliding column 242 slidably inserted in the extension tube 241, and a reset member 243 installed in the extension tube 241. The reset member 243 is a spring, and one end of the spring is connected to the inner end surface of the extension tube 241, and the other end is connected to the end surface of the sliding column 242. Fig.10 , a ring groove 30 is provided on the side of the turntable 102 close to the base 18, and the inner wall of the ring groove 30 is a rough structure, such as a structure with fine stripes or other anti-slip patterns arranged at intervals. A positioning block 244 is fixed to the side wall of the end of the sliding column 242 away from the extension tube 241. Under the action of the reset member 243, the positioning block 244 is pressed against the inner wall of the ring groove 30, thereby limiting the rotation of the turntable 102. A resistance bar 25 is fixed to the side wall of the meshing bar 11. The resistance bar 25 is vertically arranged. A corresponding through groove 31 for the resistance bar 25 to slide is provided on the sliding plate 51, and the resistance bar 25 can also slide horizontally. When the engagement bar 11 and the turntable 102 are engaged, the abutment bar 25 abuts against the end of the sliding column 242, and the sliding column 242 is pressed by the abutment bar 25 and slides into the extension tube 241, so that the positioning block 244 is separated from the inner wall of the annular groove 30, thereby not affecting the rotation of the turntable 102.

[0056] The implementation principle of a municipal sewage sludge concentration detection system in an embodiment of the present application is as follows: the engaging strip 11 and the turntable 102 are engaged, the giving way groove 16 and the through groove 13 are overlapped, and the detection head 3 is moved to the required position by the rotating plate 7, the sliding plate 51 and the adjusting plate 52, and then the engaging strip 11 is driven to slide by the third element 17, so that the adjusting cylinder 15 rotates, and the adjusting cylinder 15 is closed in the through groove 13, and then the detection is carried out, thereby reducing the flow of sewage and affecting the test results of the detection head 3.

[0057] Example 2: This example discloses a method for detecting the concentration of municipal sewage sludge, using the detection system described in Example 1, comprising the following steps:

[0058] (1) The rotating plate 7 is rotated to a suitable position, and then the sliding plate 51 is driven to a specified position by the first element 8, and then the adjusting plate 52 is driven downward by the second element 9, so that the detection head 3 enters the sewage for detection, and the detection can be performed at different depths by adjusting the position of the adjusting plate 52;

[0059] (2) When continuing to detect the next point, the second element 9 drives the adjustment plate 52 to slide upward, so that the detection head 3 comes out of the sewage, and then drives the rotating plate 7 to rotate, and then adjusts the position of the sliding plate 51 through the first element 8, and then drives the detection head 3 to enter the sewage through the second element 9. In this process, the positioning groove 16 and the through groove 13 overlap, so that the water in the fixed cylinder 12 can flow in and out, and then the engaging strip 11 is driven to move by the third element 17, that is, the rotating cylinder can rotate and close the through groove 13, so that the detection head 3 can detect the sewage in the fixed cylinder 12.

[0060] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
