Description

Technical Field

[0001] The invention relates to the technical field of polluted water source analysis and relates to an automated analysis platform for polluted water source samples. Background Art

[0002] With the acceleration of industrialization and urbanization, environmental pollution problems have become increasingly prominent, among which water pollution is particularly serious. Polluted water sources not only affect the safety of human drinking water, but also cause great damage to the ecological environment. Therefore, it is particularly important to accurately and efficiently analyze and monitor polluted water sources. However, in actual operation, the analysis of polluted water sources faces many challenges, such as complex sample sources, a wide variety of pollutants, and large concentration differences, which put forward higher requirements on the accuracy and sensitivity of analytical techniques.

[0003] Traditional methods for analyzing polluted water sources mostly rely on manual operations, which have problems such as low efficiency and large errors. Manual operations are not only time-consuming and laborious, but are also easily affected by the skill level and experience of the operator, resulting in instability and uncertainty in the analysis results. In addition, although the existing automated analysis equipment has improved the analysis efficiency to a certain extent, it still cannot fully and real-time detect various pollutants in polluted water samples. Flotation fluid detection is one of the important links in polluted water source analysis.

[0004] Through flotation technology, pollutants such as suspended solids, oils, and organic matter in water can be enriched for subsequent analysis and detection. However, the existing flotation liquid detection technology is insufficient in terms of accuracy. On the one hand, the flotation process is easily interfered by various factors, such as temperature, pH value, ionic strength, etc., which leads to the instability and unpredictability of the flotation effect; on the other hand, the existing detection technology still has certain errors and limitations in the determination of the types and concentrations of pollutants in the flotation liquid.

[0005] With respect to the above-mentioned related technologies, the existing flotation technology can enrich pollutants such as suspended matter, oil and organic matter in water to facilitate subsequent analysis and detection. However, the flotation liquid detection technology can only monitor the pollutants on the liquid surface of the polluted water source sample. The determination of the types and concentrations of pollutants on the liquid surface in the flotation liquid still has certain errors and limitations. Summary of the invention

[0006] In order to solve the technical problem of errors in the determination of the types and concentrations of pollutants on the liquid surface of contaminated water source samples, the present application provides an automated analysis platform for contaminated water source samples, which can comprehensively and real-time detect various pollutants in contaminated water source samples and reduce the impact of human errors and interference factors.

[0007] This application provides an automated analysis platform for polluted water samples, which adopts the following technical solutions: An automated analysis platform for polluted water source samples comprises a vertically arranged measuring cylinder and an adjusting component arranged inside the measuring cylinder, wherein the adjusting component comprises a floating ball vertically sliding inside the measuring cylinder, a linear guide shaft installed at the center position of the bottom of the floating ball, an assembly ring coaxially arranged on the periphery of the linear guide shaft, a plurality of linear bars connected between the assembly ring and the linear guide shaft, and a plurality of automated analysis instruments fixedly installed on the circumference of the assembly ring; the floating ball can be inflated to expand or deflated to shrink, and the automated analysis instrument is used to detect various pollutants in the polluted water source samples in real time.

[0008] By adopting the above technical solution, the existing polluted water source injection equipment injects the polluted water source sample into the inner side of the measuring cylinder through the delivery pipe, and the float can achieve the effect of inflation and deflation through gas. The float drives the automated analysis instrument to be at different heights of the polluted water source sample with the help of the buoyancy of the polluted water source sample, so that the automated analysis instrument can detect various pollutants in the polluted water source sample at different heights in the measuring cylinder, thereby achieving the effect of the automated analysis instrument comprehensively detecting various pollutants in the polluted water source sample.

[0009] Optionally, an anti-roll component is provided in the measuring cylinder, and the anti-roll component includes an airbag ring that slides vertically in the measuring cylinder, and a plurality of elastic strips connected between the inner circumference of the airbag ring and the outer circumference of the float; the outer circumference of the airbag ring is fitted to the inner circumference of the measuring cylinder.

[0010] By adopting the above technical solution, the airbag ring can avoid the problem that the float ball rolls over and causes several automated analysis instruments to tilt or expose the liquid surface, and can ensure that several automated analysis instruments are immersed in the inner side of the contaminated water source sample in the vertical direction.

[0011] Optionally, a liquid level monitoring component is provided in the measuring cylinder, and the liquid level monitoring component includes an angle frame arranged outside the measuring cylinder, a liquid level pan arranged on the float, a plurality of position transmitters embedded in the circumferential edge of the liquid level pan, and a position receiver fixedly installed on the angle frame close to the outer wall of the measuring cylinder along the length direction of the measuring cylinder; the liquid level pan is made of a composite material that can float on the liquid surface of the contaminated water source sample.

[0012] By adopting the above technical solution, the liquid level pan floats on the liquid surface of the contaminated water source sample, and several position transmitters around the liquid level pan transmit signals of the liquid level of the contaminated water source sample to the position receiver in real time to determine the liquid level position of the contaminated water source sample in the measuring cylinder.

[0013] Optionally, a gas filling component is provided in the measuring cylinder, and the gas filling component includes a plurality of gas supply hoses vertically fixed to the top of the float, a cavity disc provided above the measuring cylinder, and a gas filling pipe vertically fixed to the top of the cavity disc; the top ends of the plurality of gas supply hoses are vertically fixed to the bottom of the cavity disc, and the gas filling pipe is fixedly connected to the plurality of gas supply hoses.

[0014] By adopting the above technical scheme, the existing gas filling equipment can fill gas toward several gas hoses through the filling pipe, and the gas is filled into the float through the gas hose. The float can achieve the effect of inflation and deflation through the gas; the float uses the buoyancy of the contaminated water source sample to drive the automated analysis instrument to be at different heights of the contaminated water source sample.

[0015] Optionally, a cleaning component is provided outside the cavity disc, and the cleaning component includes a plurality of nozzles installed at the bottom of the cavity disc and a cleaning pipe vertically fixed to the top of the cavity disc; the cleaning pipes are fixedly connected to the plurality of nozzles.

[0016] By adopting the above technical solution, the cleaning liquid filling device can fill the cleaning liquid toward the plurality of nozzles through the cleaning pipeline, and the cleaning liquid at this time cleans the gas delivery hose and the internal structure of the measuring cylinder through the plurality of nozzles.

[0017] Optionally, a tension component is provided at the top of the folding frame, and the tension component includes a cylinder fixedly installed on the outer wall of the folding frame close to the measuring cylinder, a tension sensor fixedly installed on the end of the piston rod of the cylinder away from the folding frame, and a steel wire strand connected to the end of the tension sensor away from the cylinder; the end of the steel wire strand away from the tension sensor is fixedly installed on the top of the cavity disc.

[0018] By adopting the above technical solution, the cylinder pulls the cavity disc through the steel wire strand to slide in the vertical upward direction, and the plurality of gas hoses slide in the vertical upward direction, thereby reducing the influence of the gravity of the cavity disc and the plurality of gas hoses on the floating of the floating ball. The value of the tension sensor reaches the threshold value preset by the control module, indicating that the gravity of the cavity disc and the plurality of gas hoses at this time has no influence on the floating of the floating ball.

Several of the automated analytical instruments have the same height with reference to the inner bottom surface of the measuring cylinder, and the distance measuring sensor is used to monitor the distance between the automated analytical instrument and the inner bottom surface of the measuring cylinder in real time.

[0020] By adopting the above technical solution, the float uses the buoyancy of the contaminated water source sample to drive the automated analysis instrument to different heights of the contaminated water source sample, and the distance measuring sensor at the bottom end of the linear guide shaft monitors the distance between the automated analysis instrument and the inner bottom surface of the measuring cylinder in real time, thereby enabling the automated analysis instrument to detect various pollutants in the contaminated water source sample at different heights of the contaminated water source sample in the measuring cylinder.

[0021] Optionally, the float is smaller than the cross-sectional size of the measuring cylinder, and a gap is left between the outer circumference of the float and the inner circumference of the measuring cylinder.

[0022] By adopting the above technical scheme, the float can achieve the effect of inflation and expansion and deflation and contraction through gas. The float uses the buoyancy of the contaminated water source sample to drive the automated analysis instrument to be at different heights of the contaminated water source sample, so that the automated analysis instrument can detect various pollutants in the contaminated water source sample at different heights of the contaminated water source sample in the measuring cylinder, thereby achieving a more comprehensive and accurate measurement of the contaminated water source sample.

[0023] Optionally, the measuring cylinder is made of a transparent material, and the bottom of the measuring cylinder is connected to an existing polluted water source injection device through a delivery pipe.

[0024] By adopting the above technical solution, the measuring cylinder is made of transparent material, which is convenient for the staff to better observe the situation inside the measuring cylinder; and the filling port of the measuring cylinder is arranged at the bottom of the measuring cylinder, which can make the existing polluted water source filling equipment fill the polluted water source more convenient.

[0025] In summary, the present application includes at least one of the following beneficial technical effects: 1. The existing polluted water source injection equipment injects the polluted water source sample into the inner side of the measuring cylinder through the delivery pipe, and the float can achieve the effect of inflation and deflation through gas. The float uses the buoyancy of the polluted water source sample to drive the automated analysis instrument to different heights of the polluted water source sample, so that the automated analysis instrument can detect various pollutants in the polluted water source sample at different heights in the measuring cylinder, and achieve the effect of the automated analysis instrument comprehensively detecting various pollutants in the polluted water source sample; 2.

DETAILED DESCRIPTION

[0030] The following is combined with Figure 1-3 This application is described in further detail.

[0031] Refer to the attached Figure 1-3 An automated analysis platform for polluted water source samples includes a vertically arranged measuring cylinder 11, a delivery pipe 12 is arranged on the outer peripheral surface of the bottom of the measuring cylinder 11, the measuring cylinder 11 is connected to the polluted water source perfusion device through the delivery pipe 12, and the measuring cylinder 11 is made of a transparent material. A folding frame 13 is arranged on the periphery of the measuring cylinder 11 along the vertical direction, and the bottom end of the folding frame 13 is fixedly connected to the outer peripheral surface of the bottom of the measuring cylinder 11.

[0032] Refer to the attached Figure 1-3A float 14 that can be inflated and deflated is provided on the inner side of the measuring cylinder 11 and slides along the vertical direction. When the float 14 is inflated to the maximum, the cross-sectional size of the float 14 is smaller than the cross-sectional size of the measuring cylinder 11, so that a gap is left between the outer circumference of the float 14 and the inner circumference of the measuring cylinder 11. A linear guide shaft 15 is fixedly installed at the center of the bottom of the float 14 along the vertical direction, and a distance sensor 16 is fixedly installed at the bottom end of the linear guide shaft 15. An assembly ring 17 is coaxially provided on the periphery of the linear guide shaft 15, and a plurality of straight lines 18 are fixedly connected between the inner circumference of the assembly ring 17 and the outer circumference of the linear guide shaft 15. The assembly ring 17 is fixedly installed with a plurality of automated analysis instruments 19 at equal intervals in the circumferential direction with its own axis as the center.

[0033] Refer to the attached Figure 1-3 The automated analysis instrument 19 is used to detect various pollutants (such as heavy metals, organic pollutants, microorganisms, etc.) in the polluted water source sample in real time. Several automated analysis instruments 19 have the same height with the inner bottom surface of the measuring cylinder 11 as a reference. The distance sensor 16 is used to monitor the distance between the automated analysis instrument 19 and the inner bottom surface of the measuring cylinder 11 in real time. An airbag ring 20 is provided on the inner side of the measuring cylinder 11 to slide along the vertical direction. The outer circumference of the airbag ring 20 is fitted with the inner circumference of the measuring cylinder 11. An elastic strip 21 is fixedly connected between the inner circumference of the airbag ring 20 and the outer circumference of the float 14.

[0034] Refer to the attached Figure 1-3 , a plurality of elastic strips 21 are arranged around the axis of the float 14. When the polluted water source sample is poured into the measuring cylinder 11, the airbag ring 20 can prevent the float 14 from rolling over and causing a plurality of automated analysis instruments 19 to tilt or expose the liquid surface. A liquid level pan 22 is arranged above the float 14. The liquid level pan 22 is made of a composite material that can float on the liquid surface of the polluted water source sample. Position transmitters 23 are embedded in the circumferential edge of the liquid level pan 22. A plurality of position transmitters 23 are arranged at equal intervals around the axis of the liquid level pan 22. A position receiver 24 is fixedly installed on the outer wall of the measuring cylinder 11 near the angle frame 13 along the length direction of the measuring cylinder 11. The liquid level position of the polluted water source sample in the measuring cylinder 11 is monitored in real time by the position transmitter 23 and the position receiver 24.

[0035] Refer to the attached Figure 1-3, a plurality of air hoses 25 are fixedly installed on the top of the float 14 in the vertical direction, a cylinder 26 is fixedly installed on the top of the angle frame 13 near the outer wall of the measuring cylinder 11 in the horizontal direction, and a tension sensor 27 for measuring tension is fixedly installed on the end of the piston rod of the cylinder 26 away from the angle frame 13. A sleeve 28 in a right angle shape is fixedly installed on the outer wall of the measuring cylinder 11 of the angle frame 13, and a pulley 29 is rotatably installed at the angled part of the sleeve 28, and the cylinder 26 and the tension sensor 27 are inserted into the inner side of the sleeve 28. A steel strand 30 is fixedly connected to the end of the tension sensor 27 away from the cylinder 26, and the end of the steel strand 30 away from the tension sensor 27 passes around the outer peripheral surface of the pulley 29.

[0036] Refer to the attached Figure 1-3 A cavity disc 31 is provided below the sleeve 28, the top ends of several gas hoses 25 are vertically fixed to the bottom of the cavity disc 31, and the end of the steel strand 30 away from the tension sensor 27 is fixed to the top of the cavity disc 31 along the vertical direction. Several nozzles 32 are evenly installed at the bottom of the cavity disc 31, and a gas filling pipeline 33 and a cleaning pipeline 34 are vertically fixed to the top of the cavity disc 31. The cleaning pipeline 34 is fixedly connected to the several nozzles 32 through a conduit, and the cleaning liquid filling device can fill the cleaning liquid toward the several nozzles 32 through the cleaning pipeline 34. The gas filling pipeline 33 is fixedly connected to the several gas hoses 25 through an air pipe, and the gas filling device can fill gas toward the several gas hoses 25 through the gas filling pipeline 33.

[0037] The implementation principle of an automated analysis platform for polluted water source samples is as follows: the existing polluted water source filling equipment fills the polluted water source sample toward the inner side of the measuring cylinder 11 through the delivery pipe 12, and the liquid level plate 22 floats on the liquid surface of the polluted water source sample. Several position transmitters 23 around the liquid level plate 22 transmit signals of the liquid level of the polluted water source sample toward the position receiver 24 in real time to determine the liquid level position of the polluted water source sample in the measuring cylinder 11. Several automated analysis instruments 19 under the float 14 detect various pollutants (such as heavy metals, organic pollutants, microorganisms, etc.) in the polluted water source sample in real time.

[0038] The existing gas filling equipment can fill gas toward a plurality of gas hoses 25 through the filling pipe 33, and the gas is filled into the float 14 through the gas hose 25. The float 14 can achieve the effect of inflation and deflation through the gas. The float 14 drives the automatic analysis instrument 19 to be at different heights of the polluted water source sample by means of the buoyancy of the polluted water source sample, and the distance sensor 16 at the bottom end of the linear guide shaft 15 monitors the distance between the automatic analysis instrument 19 and the inner bottom surface of the measuring cylinder 11 in real time, so that the automatic analysis instrument 19 can detect various pollutants in the polluted water source sample when the polluted water source sample in the measuring cylinder 11 is at different heights.

[0039] The airbag ring 20 tries to prevent the float 14 from rolling over, which would cause several automated analytical instruments 19 to tilt or expose the liquid surface. At the same time, the cylinder 26 pulls the cavity disc 31 to slide in the vertical upward direction through the steel wire rope 30, and the cavity disc 31 drives several gas hoses 25 to slide in the vertical upward direction, thereby reducing the influence of the gravity of the cavity disc 31 and several gas hoses 25 on the floating of the float 14. The value of the tension sensor 27 reaches the threshold value pre-set by the control module, indicating that the gravity of the cavity disc 31 and several gas hoses 25 at this time has no influence on the floating of the float 14. The cleaning liquid filling device can fill the cleaning liquid toward several nozzles 32 through the cleaning pipe 34, and the cleaning liquid cleans the gas hose 25 and the internal structure of the measuring cylinder 11 through several nozzles 32.

[0040] The above are all preferred embodiments of the present application and are not intended to limit the protection scope of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
