Description

Technical Field

[0001] This invention relates to the field of wastewater testing technology, and more specifically, to an on-site analysis device for wastewater. Background Technology

[0002] With rapid economic development and increased industrialization, industrial wastewater pollution of the environment is becoming increasingly severe. In order to understand the water quality status and take corresponding treatment measures, it is necessary to use wastewater analysis equipment to quickly detect wastewater and analyze various parameters in the wastewater. This can provide real-time data to help staff quickly grasp the changing trends of wastewater quality so as to take appropriate treatment measures.

[0003] To reduce the impact of random errors that may occur in a single test, it is usually necessary to test wastewater samples from the same area multiple times. However, while existing wastewater testing and analysis devices can analyze wastewater samples, they cannot automatically and evenly distribute the same wastewater sample, nor can they perform convenient and efficient multiple tests on the same wastewater sample. Therefore, to improve the accuracy of the test results, staff need to operate the testing device multiple times to complete the wastewater sample analysis, resulting in poor practicality and low work efficiency. Therefore, there is a need to provide a field analysis device for wastewater to meet the needs of users. Summary of the Invention

[0016] The working principle and beneficial effects of this invention are as follows:

[0017] 1. This invention includes a uniform sample distribution component.

This, in turn, drives the first and second mixing plates on the connecting ring to perform automatic and stable up-and-down reciprocating motion during rotation. This ensures that the wastewater sample in the treatment cylinder is uniformly stirred in all directions, guaranteeing the even distribution of various substances in the sample. This allows the sample to reflect the overall characteristics and pollution status of the wastewater, avoiding uneven sample distribution that could affect the accuracy of subsequent detection and analysis results. Subsequently, through the cooperation of the first and second guide pipes, combined with the sample distribution cylinder and the separator, the wastewater sample can be automatically and uniformly distributed. By uniformly distributing the wastewater, the same sample can be analyzed multiple times, reducing errors in the detection and analysis results and improving the accuracy of the detection and analysis work.

[0018] 2. This invention includes an automatic analysis component. The downward movement of the sampling cylinder automatically presses down on each detection cylinder. Under air pressure, the first rubber piston automatically inflates the rubber airbag, thus automatically clamping and positioning each detection cylinder. Combined with the corresponding third guide tube on the sampling cylinder, the separated wastewater sample is automatically transported into each detection cylinder for subsequent analysis. Furthermore, driven by the drive motor, and with the guide rod on the turntable and the guide groove on the guide plate, the rotating shaft drives each detection cylinder to rotate intermittently, 90° each time, automatically switching the position of each detection cylinder. Combined with the water quality analyzer and the detection head, batch analysis of wastewater samples in each detection cylinder can be performed automatically and efficiently, effectively improving the ease of use and work efficiency of the on-site analysis device.

[0019] 3. The present invention is equipped with a rubber suction cup. When the analytical device is working on site, the top plate is driven downward by the hydraulic rod. Combined with the device shell and rubber frame, the whole device can be conveniently protected. At the same time, the top plate can drive the end of the coil to move downward. At this time, under the elastic action of the spiral spring, the second threaded rod can be automatically driven. Combined with the second rubber piston on the threaded sleeve rod and the rubber suction cup on the gas storage frame, the analytical device can be automatically adsorbed and fixed on the placement platform, ensuring the stability and safety of the analytical device in the field, and increasing the versatility and stability of the analytical device.

[0040] Example 2

[0041] like Figures 1 to 15 As shown, based on the same concept as Embodiment 1 above, this embodiment also proposes an on-site analysis device for wastewater.

[0042] In this embodiment, a device housing 6 is welded and fixed to the top surface of the base plate 1, and a rubber frame 7 is fixedly connected to the bottom surface of the top plate 4. Hydraulic rods 3 are symmetrically distributed on both sides of the top plate 4. The inner wall of the rubber frame 7 is in contact with the outer wall of the limiting frame 9. By driving the hydraulic rods 3, the top plate 4 is driven to move downward. At this time, under the cooperative action of the rubber frame 7 and the device housing 6, the entire device can be protected.

[0043] In this embodiment, the processing cylinder 501 is welded and fixed to the top surface of the top plate 4. A filter cylinder 502 is slidably connected inside the processing cylinder 501. A fixing rod 503 is welded and fixed to the bottom surface of the filter cylinder 502. A slot 504 is provided on the top side of the processing cylinder 501. A connecting plate 506 is welded and fixed to the bottom surface of the connecting frame 505. A return spring 507 is welded and fixed to the connecting plate 506. A locking rod 508 is welded and fixed to the return spring 507. The locking rod 508 is slidably connected to the connecting plate 506, and its end engages with the slot 504. The outer wall of the filter cylinder 502 fits into the inner wall of the treatment cylinder 501. The top surface of the filter cylinder 502, the top surface of the treatment cylinder 501, and the bottom surface of the connecting frame 505 are on the same horizontal plane.

[0044] In this embodiment, a first guide pipe 518 is connected to the bottom center of the processing cylinder 501, and a solenoid valve is installed on the first guide pipe 518. A second guide pipe 519 is connected to the bottom side of the first guide pipe 518. A sample distribution cylinder 520 is welded and fixed to the bottom surface of the top plate 4. A partition plate 521 is welded and fixed inside the sample distribution cylinder 520. A third guide pipe 522 is connected to the bottom of the sample distribution cylinder 520. The bottom of the first guide pipe 518 is located inside the partition plate 521. The sample distribution cylinder 520 is located directly below the processing cylinder 501. The cross-section of the partition plate 521 is cross-shaped. There are four second guide pipes 519 and four third guide pipes 522. The four second guide pipes 519 are distributed at equal angles at the bottom of the first guide pipe 518, and the four third guide pipes 522 are distributed at equal angles at the bottom of the sample distribution cylinder 520. Connecting blocks 514 are symmetrically distributed on the connecting blocks. On both sides of ring 515, connecting blocks 514 correspond one-to-one with circular gears 512 via reciprocating screws 511. First mixing plates 516 are distributed at equal angles on connecting ring 515, and second mixing plates 517 are symmetrically distributed on the upper and lower sides of the first mixing plates 516. Driven by the first servo motor 509, and in combination with the circular gears 512 and internal gears 513, the reciprocating screws 511 on both sides can rotate automatically during the revolution. This, in turn, can drive the first mixing plates 516 and the second mixing plates 517 on connecting ring 515 to perform automatic and stable up-and-down reciprocating motion during rotation. This allows for all-round uniform stirring of the wastewater sample in the treatment cylinder 501, ensuring that various substances in the sample are evenly distributed, so that it can reflect the overall characteristics and pollution status of the wastewater, and avoid uneven sample distribution affecting the accuracy of subsequent detection and analysis results.

[0045] In this embodiment, the automatic analysis component 8 includes a second servo motor 801 and a rotating shaft 811. The second servo motor 801 is welded and fixed inside the base plate 1, which is made of mesh material. The output end of the second servo motor 801 is connected to a first threaded rod 802, which is rotatably connected inside the base plate 1.

The detection head 822 is bolted to a connecting plate 823, which is welded to the side of the sample cylinder 520. The side end face of the guide plate 812 is arc-shaped. Driven by the drive motor 807, and in conjunction with the guide rod 810 on the turntable 808 and the guide grooves 813 on the guide plate 812, the rotating shaft 811 can drive each detection cylinder 819 to rotate intermittently, with each rotation being 90°. This automatically switches the position of each detection cylinder 819. Combined with the water quality analyzer 820 and the detection head 822, the wastewater samples in each detection cylinder 819 can be automatically and efficiently analyzed in batches, effectively improving the ease of use and work efficiency of the on-site analysis device.

[0046] In this embodiment, a first support plate 814 and a second support plate 824 are rotatably connected inside the positioning cylinder 804. A positioning groove 805 is provided through the second support plate 824, and a rubber airbag 806 is fixedly connected inside the positioning groove 805. The rubber airbag 806 is cylindrical in shape, and a rotating shaft 811 is welded and fixed to the first support plate 814 and the second support plate 824. An air storage cylinder 815 is welded and fixed to the top surface of the first support plate 814, and a connecting spring 816 is welded and fixed to the bottom surface inside the air storage cylinder 815. A first rubber piston 817 is fixedly connected to the connecting spring 816. Four positioning grooves 805 are provided, and the four positioning grooves 805 are distributed at equal angles on the second support plate 824. The positioning grooves 805 are respectively connected to the rubber airbag 806 and the air storage cylinder 815. In a one-to-one correspondence, the gas storage cylinder 815 is located directly below the positioning groove 805. The first rubber piston 817 is slidably connected inside the gas storage cylinder 815. The bottom side of the gas storage cylinder 815 is connected to the air guide pipe 818, and the top end of the air guide pipe 818 is connected to the side of the rubber air bag 806. The positioning groove 805 is equipped with a detection cylinder 819. By moving the sample distribution cylinder 520 downward, each detection cylinder 819 can be automatically pressed. Under the action of air pressure, the first rubber piston 817 can automatically inflate the rubber air bag 806, thereby automatically clamping and positioning each detection cylinder 819. Combined with the corresponding third guide pipe 522 on the sample distribution cylinder 520, the sampled sewage sample can be automatically transported to each detection cylinder 819 for subsequent detection and analysis.

[0047] In this embodiment, a second threaded rod 11 is rotatably connected inside the limiting frame 9. A spiral spring 10 is welded and fixed inside the limiting frame 9. The inner end of the spiral spring 10 is welded and fixed to the second threaded rod 11. A coil 12 is welded and fixed to the second threaded rod 11. A traction rope 13 is wound around the coil 12. The top end of the traction rope 13 is fixedly connected to the bottom end surface of the top plate 4. An air storage frame 16 is welded and fixed inside the bottom plate 1. A rubber suction cup 17 is connected to the air storage frame 16. A threaded sleeve 14 is threadedly connected to the second threaded rod 11. A second rubber piston 15 is fixedly connected to the threaded sleeve 14. The piston 15 is slidably connected inside the gas storage frame 16, which is symmetrically distributed on both sides of the bottom plate 1. The rubber suction cups 17 are equidistantly distributed at the bottom of the gas storage frame 16. The traction rope 13 passes through and is slidably connected to the gas storage frame 16 and the bottom plate 1. The top plate 4 can drive the end of the coil 12 to move down. Under the elastic action of the spiral spring 10, it can automatically drive the second threaded rod 11. Combined with the second rubber piston 15 on the threaded sleeve rod 14 and the rubber suction cups 17 on the gas storage frame 16, the analyzer can be automatically adsorbed and fixed on the placement platform, ensuring the stability and safety of the analyzer in the field.

[0048] It should be noted that the present invention is an on-site analysis device for wastewater. First, the operator can drive the hydraulic rod 3 on the fixed plate 2. At this time, the hydraulic rod 3 can push the top plate 4 upward. The top plate 4 can drive the rubber frame 7 to move away from the device housing 6. Then, the operator can place the various detection cylinders 819 to be used into the various positioning slots 805 on the second support plate 824 and place the entire device on the workbench. During the upward movement of the top plate 4, the coil 12 can drive the second threaded rod 11 to rotate automatically. Under the rotation of the second threaded rod 11, the spiral spring 10 in the limit frame 9 can be compressed. At the same time, the threaded sleeve rod 14 connected by threads can drive the second rubber piston 15 to move towards the rubber suction cup 17 and push the air out of the rubber suction cup 17.

[0049] After each detection cylinder 819 is placed stably, the hydraulic rod 3 can be driven to move the top plate 4 downward. At this time, with the cooperation of the rubber frame 7 and the device housing 6, the entire device can be protected. At the same time, the top plate 4 can drive the top of the traction rope 13 to move downward. Therefore, under the elastic action of the spiral spring 10 inside the limit frame 9, the second threaded rod 11 can be driven to rotate automatically in the opposite direction. The threaded sleeve rod 14 connected by threads can drive the second rubber piston 15 to move automatically in the air storage frame 16 and suck the air in each rubber suction cup 17. Using the internal negative pressure of each rubber suction cup 17, the entire device can be automatically and stably adsorbed and fixed on the worktable, ensuring the stability of the subsequent working state of the entire device.

[0050] Furthermore, under the action of the top plate 4, the sample distribution cylinder 520 can press down on each detection cylinder 819. Under the downward pressing of the detection cylinder 819, the first rubber piston 817 on the connecting spring 816 can be pushed to move downward in the air storage cylinder 815. At this time, under the action of air pressure, the air at the bottom of the air storage cylinder 815 can be transported to the rubber air bag 806 through the air guide pipe 818 for automatic inflation, thereby automatically clamping and positioning the detection cylinder 819. At this time, the detection cylinder 819 is located directly below the third guide pipe 522 for subsequent sample distribution and feeding work.

[0051] Then, the staff can pull the lever 508 on the connecting plate 506 and move it away from the slot 504 on the treatment cylinder 501 to complete the disassembly and separation between the connecting frame 505 and the treatment cylinder 501. At this time, the filter cylinder 502 can be picked up and placed by grabbing the fixing rod 503 to ensure the convenience of subsequent cleaning work. After that, the staff can stably transport the sewage sample into the treatment cylinder 501. At this time, by repeating the above operation, after placing the connecting frame 505 in the treatment cylinder 501, the lever 508 can be released. Under the elastic action of the return spring 507, the lever 508 can automatically engage into the slot 504 on the treatment cylinder 501 to complete the engagement and fixation between the connecting frame 505 and the treatment cylinder 501, and prevent the sewage sample from leaking.

[0052] The first servo motor 509 on the drive connecting frame 505 can drive the sealing plate 510 to rotate through the output shaft, which in turn drives the circular gear 512 on the reciprocating screw 511 to perform circular motion. At the same time, under the meshing drive of the circular gear 512 and the internal gear 513, the reciprocating screws 511 on both sides can be driven to rotate automatically during the revolution. This can then drive the connecting ring 515 to perform automatic and stable up-and-down reciprocating motion through the threaded connecting block 514. This can then drive the first mixing plate 516 and the second mixing plate 517 on the connecting ring 515 to perform automatic and stable up-and-down reciprocating motion during the rotation, thereby achieving all-round uniform stirring of the sewage sample, ensuring that the various substances in the sample are evenly distributed, so that it can reflect the characteristics and pollution status of the overall sewage, and avoid the uneven sample distribution affecting the accuracy of subsequent detection and analysis results.

[0053] The sample distribution cylinder 520 can be divided into four independent areas by the partition plate 521. The staff only needs to open the solenoid valve on the first guide pipe 518. The sewage sample is filtered by the filter screen cylinder 502 and then transported to the corresponding independent area through the four second guide pipes 519. The four independent areas can be automatically transported to the corresponding detection cylinder 819 through the corresponding third guide pipe 522, and the sewage sample is automatically and uniformly distributed. Then, the top plate 4 is driven to move upward by the hydraulic rod 3. Since the traction rope 13 is in a loose state when the top plate 4 moves downward to the lowest point, it is not necessary to straighten the traction rope 13 when the top plate 4 moves upward, so it will not have an adverse effect on the working state of the rubber suction cup 17.

[0054] After the top plate 4 drives the sample dispensing cylinder 520 to move upward and separate from the detection cylinder 819, the second servo motor 801 can drive the first threaded rod 802 to rotate stably. The threaded slider 803 can drive the positioning cylinder 804 to move towards the detection head 822 until the rightmost detection cylinder 819 moves directly below the detection head 822. At this time, driven by the hydraulic rod 3, the top plate 4 and the connecting plate 823 can drive the detection head 822 to move downward synchronously. At this time, the connecting plate 823 can also press the detection cylinder 819 to fix it in position, and the detection head 822 can be inserted into the sewage sample in the detection cylinder 819. Combined with the water quality analyzer 820, the sewage can be tested and analyzed on site.

[0055] After the analysis of the wastewater sample inside the first detection cylinder 819 is completed, the detection head 822 moves upward and drives the drive motor 807. At this time, under the driving action of the drive motor 807, the limiting plate 809 and guide rod 810 on the turntable 808 rotate synchronously. The guide rod 810 moves into the guide groove 813 on the guide plate 812 and can move the guide plate 812 to rotate stably. Under the continuous movement of the guide rod 810, the guide plate 812 can be moved intermittently through the guide groove 813, rotating 90° each time. When the guide plate 812 stops rotating, the guide plate 812 can be limited by the contact between the limiting plate 809 and the guide plate 812, ensuring the stability of the intermittent rotation state of the guide plate 812. By utilizing the intermittent rotation of the guide plate 812, the first support plate 814 and the second support plate 824 can be driven to move synchronously through the rotating shaft 811, which in turn can drive each detection cylinder 819 to automatically and stably switch positions. Combined with the upward and downward movement of the detection head 822, the wastewater samples in each detection cylinder 819 can be automatically and efficiently analyzed in batches.

[0056] After the inspection is completed, the top plate 4 can be pushed upward by the hydraulic rod 3. The top plate 4 can drive the rubber frame 7 to move away from the device housing 6. Then, the staff can take out and clean each inspection cylinder 819 that needs to be used for subsequent reuse.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
