Description

Technical Field

[0001] This utility model relates to the field of sampling and analysis technology, specifically to an integrated wastewater sampling and analysis machine for simultaneous detection of multiple parameters. Background Technology

[0002] With the rapid development of industrialization and urbanization, the amount of sewage discharged has increased dramatically and its composition has become increasingly complex. Industrial wastewater contains heavy metals, organic pollutants, etc., while domestic sewage contains nutrients such as nitrogen and phosphorus, as well as pathogenic microorganisms. If these sewages are discharged directly without effective treatment, they will seriously pollute the water environment, threaten the ecological balance and human health. Therefore, accurate, rapid and comprehensive monitoring of wastewater quality and timely understanding of pollution status are extremely important for sewage treatment and environmental supervision. Existing technologies mostly employ single-parameter detection devices or multi-device step-by-step detection modes, which cannot achieve simultaneous analysis of multiple parameters of wastewater. Therefore, we propose an integrated wastewater sampling and analysis machine for simultaneous detection of multiple parameters. Utility Model Content

[0003] The purpose of this invention is to provide an integrated wastewater sampling and analysis machine that can simultaneously detect multiple parameters.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a multi-parameter synchronous detection wastewater sampling and analysis integrated machine, including a frame, the inner wall of which includes a detection component and a sampling component; The detection assembly includes a detector, a positioning block, a pressing block, a fixing plate, a limiting block, and a connecting plate. The side of the detector is slidably connected to the inner wall of the frame. One side of the connecting plate is rotatably connected to the side of the limiting block, and the other side of the connecting plate is rotatably connected to the side of the fixing plate. The side of the limiting block is engaged with the inner wall of the detector. The side of the pressing block is slidably connected to the positioning block and the inner wall of the detector. The sampling assembly includes a liquid pump, a collection tube, a manifold, a main pipe, and a branch pipe. One end of the collection tube is connected to the inlet of the liquid pump, one end of the main pipe is connected to the outlet of the liquid pump, one end of the branch pipe is connected to the inner wall of the main pipe, and the manifold is located inside the frame.

[0005] As a further embodiment of this utility model: the side of the positioning block is connected to the side of the frame, and the side of the positioning block is slidably connected to the inner wall of the detector.

[0006] As a further embodiment of this utility model: the side of the limiting block is slidably connected to the inner wall of the positioning block.

[0007] As a further embodiment of this utility model: the side of the pressing block is connected to the side of the fixing plate, and the side of the fixing plate is slidably connected to the inner wall of the positioning block.

[0008] As a further embodiment of this utility model: the interior of the branch pipe is connected to the interior of the detector, and the liquid outlet of the detector is connected to the manifold.

[0010] As a further embodiment of this utility model: a drain pipe is connected to the side of the frame, and the interior of the drain pipe is connected to the interior of the manifold.

[0011] Compared with the prior art, the beneficial effects of this utility model by adopting the above technical solution are as follows: 1. This utility model achieves a significant improvement in wastewater detection efficiency through a sampling component diversion and multiple detectors in parallel structural design. Structurally, the main pipe and branch pipes in the sampling component form a diversion channel. The liquid pump distributes the collected wastewater to multiple branch pipes through the main pipe. Each branch pipe corresponds to a detector, which can simultaneously detect multiple parameters in the wastewater (such as pollutant concentration, pH, etc.) in parallel. This avoids the time-consuming problem of traditional single-parameter detection equipment detecting one by one, and meets the needs for rapid analysis of wastewater and timely understanding of water quality. It is especially suitable for scenarios that require high-frequency, multi-index monitoring. 2. This utility model provides convenience for the maintenance and replacement of the detector through the mechanical linkage structure of the detection components, effectively reducing the difficulty of operation. When the detector needs to be calibrated, repaired or replaced, simply press the pressing block, and the fixing plate will drive the connecting plate to pull the limiting block, so that the limiting block is disengaged from the inner wall of the detector. Then the detector can be slid directly out from the inner wall of the frame. After maintenance is completed, the reverse operation can be performed to reset and fix it, without the need for complicated tools or disassembling a large number of structures.

[0015] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that the description of these embodiments is for the purpose of helping to understand this utility model, but does not constitute a limitation on this utility model.

[0016] Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0017] Please see the appendix Figure 1 -Appendix Figure 6 The present invention is a multi-parameter synchronous detection wastewater sampling and analysis integrated machine, including a frame 1, the inner wall of which includes a detection component 2 and a sampling component 3; In Embodiment 1, the detection component 2 includes a detector 21, a positioning block 22, a pressing block 23, a fixing plate 24, a limiting block 25, and a connecting plate 26. The side of the detector 21 is slidably connected to the inner wall of the frame 1. One side of the connecting plate 26 is rotatably connected to the side of the limiting block 25, and the other side of the connecting plate 26 is rotatably connected to the side of the fixing plate 24. The side of the limiting block 25 is engaged with the inner wall of the detector 21. The side of the pressing block 23 is slidably connected to the positioning block 22 and the inner wall of the detector 21. The side of the positioning block 22 is connected to the side of the frame 1. The side of the positioning block 22 is slidably connected to the inner wall of the detector 21. The side of the limiting block 25 is slidably connected to the inner wall of the positioning block 22. The side of the pressing block 23 is connected to the side of the fixing plate 24. The side of the fixing plate 24 is slidably connected to the inner wall of the positioning block 22. Specifically, the positioning block 22 has a sliding groove inside that matches the fixing plate 24 and the limiting block 25. The width and thickness of the fixing plate 24 are closely fitted with the inner wall of the sliding groove to ensure that the fixing plate 24 can slide smoothly along the sliding groove when the pressing block 23 is under force, avoiding jamming. The connecting plate 26 is made of elastic metal material, and its length and rotation angle are designed so that when the fixing plate 24 slides down, the connecting plate 26 can just pull the limiting block 25 to retract towards the inside of the positioning block 22, completely disengaging from the snap-fit ​​groove on the inner wall of the detector 21. Conversely, when the fixing plate 24 is reset, the connecting plate 26 can push the limiting block 25 to re-snap into the snap-fit ​​groove, achieving seamless locking. The end of the limiting block 25 that contacts the detector 21 has a protrusion, and the inner wall of the detector 21 has a groove at the corresponding position. The shape of the protrusion and the groove match, which not only ensures that the limiting block 25 is not easy to fall off when it is snapped on, but also avoids that the snapping is too tight and makes disassembly and assembly difficult. At the same time, the arc structure can reduce the frictional wear between the limiting block 25 and the detector 21 and extend the service life of the components.

[0018] In embodiment 2, the sampling assembly 3 includes a liquid pump 31, a collection tube 32, a manifold 33, a main pipe 34, and a branch pipe 35. One end of the collection tube 32 is connected to the inlet end of the liquid pump 31, one end of the main pipe 34 is connected to the outlet end of the liquid pump 31, and one end of the branch pipe 35 is connected to the inner wall of the main pipe 34. The manifold 33 is located inside the frame 1, the inside of the branch pipe 35 is connected to the inside of the detector 21, the outlet end of the detector 21 is connected to the inside of the manifold 33, the side of the branch pipe 35 is connected to the inner wall of the frame 1, the side wall of the liquid pump 31 is connected to the inner wall of the frame 1, and a drain pipe 4 is connected to the side of the frame 1. The inside of the drain pipe 4 is connected to the inside of the manifold 33. Specifically, the liquid pump 31 is a fixed-frequency, fixed-quantity model, and its output flow rate is calibrated (e.g., 100 ml / min) to ensure that the wastewater in the main pipe 34 can be evenly distributed to each branch pipe 35 (e.g., when there are 6 branch pipes 35, the flow rate of each branch pipe 35 is about 16.7 ml / min). A flow distributor is provided at the connection between the main pipe 34 and the branch pipes 35 to further ensure the consistency of the flow rate of each branch pipe 35. This avoids the wastewater overflowing from the detector 21 due to excessive flow rate in one branch pipe 35, or the detection time being prolonged due to insufficient flow rate. This ensures the consistency of the detection conditions of multiple detectors 21 and improves the comparability of multi-parameter detection results.

[0019] Working principle: First, the liquid pump 31 in the sampling component 3 is started. The operation of the liquid pump 31 generates negative pressure suction, and the external wastewater to be tested is sucked in through the collection pipe 32. It flows along the collection pipe 32 to the inlet end of the liquid pump 31. After being pressurized by the liquid pump 31, the wastewater enters the main pipe 34 from the outlet end of the liquid pump 31. The wastewater inside the main pipe 34 is then diverted through multiple branch pipes 35. Each branch pipe 35 delivers a quantitative amount of wastewater to the corresponding detector 21, providing samples for multi-parameter synchronous detection. Before testing, the detector 21 is initially positioned by the positioning block 22. At the same time, the limiting block 25 is engaged with the inner wall of the detector 21 under the linkage of the connecting plate 26 and the fixing plate 24 (the side of the limiting block 25 is slidably connected to the inner wall of the detector 21 and then locked), ensuring that the detector 21 is stable in position during the testing process and avoiding the impact of vibration on the testing accuracy. The wastewater sample entering the detector 21 is simultaneously analyzed and detected for multiple parameters (such as pollutant concentration, pH, etc.) inside the detector 21. The specific detection principle needs to be combined with the detection technology of the detector 21 itself, but the core of the integrated machine is to achieve the goal of multi-parameter synchronization by splitting the flow through the branch pipe 35 to realize the parallel operation of multiple detectors 21. If the detector 21 needs maintenance or replacement, press the pressing block 23. The pressing block 23 will drive the fixing plate 24 to slide on the inner wall of the positioning block 22. The fixing plate 24 will pull the limiting block 25 away from the snap-fit ​​state of the inner wall of the detector 21 through the connecting plate 26. At this time, the detector 21 can be slid out from the inner wall of the frame 1. After the operation is completed, the reverse reset can be used to fix it again. This mechanical linkage structure improves the convenience of equipment maintenance. After each detector 21 completes its test, the waste liquid generated is discharged from the outlet of the detector 21 and flows directly into the manifold 33 inside the frame 1. The manifold 33 collects all the waste liquid in a centralized manner, preventing the waste liquid from scattering and contaminating the inside of the equipment. The waste liquid in the manifold 33 is discharged to the outside of the equipment through the drain pipe 4 connected to the side of the frame 1. The waste liquid can then be uniformly treated (such as neutralization and purification) to ensure the environmental protection and compliance of the entire testing process. At this point, the entire workflow is complete.
