Description

Technical Field

[0001] This utility model relates to the field of time-sharing online monitoring technology, and in particular to a time-sharing online monitoring system. Background Technology

[0002] Analyzers are important devices with significant applications in scientific research, industrial production, and environmental monitoring. They can effectively break down organic matter, dissolve suspended solids, and oxidize elements in various valence states into a single high valence state or transform them into easily separable inorganic compounds.

[0003] Currently, when using an analyzer to test samples, the liquid to be tested needs to be transferred to the analyzer for testing (mainly to detect the content of COD, ammonia nitrogen, total phosphorus, and total nitrogen in the sample). Existing analyzers can only test one type of sample at a time. In addition, the detection standards for COD in the sample are different from those for ammonia nitrogen, total phosphorus, and total nitrogen. Therefore, the sample needs to be tested at least twice to obtain the content of COD, ammonia nitrogen, total phosphorus, and total nitrogen in the sample. This increases the steps, time, and effort required for sample testing and reduces the efficiency of sample testing. Utility Model Content

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] Reference Figure 1-4 One embodiment of this utility model is a time-sharing online monitoring system, comprising:

[0028] The enclosure 1 and the control panel 11 are detachably connected on one side and on one side of the enclosure 1. The enclosure 1 can be used to store the samples to be tested and the testing equipment, and at the same time, it supports the control panel 11.

[0029] Digester 3 is fixedly connected to one side of control panel 11. A photoelectric meter 9 for measuring liquid is fixedly installed on the side of control panel 11 near digester 3. The photoelectric meter 9 is used to measure the mass and volume of the sample. Before the sample is tested, the sample needs to be transferred into the photoelectric meter 9. After the mass of the sample reaches the predetermined value, the sample in the photoelectric meter 9 is transferred into digester 3 to detect the COD content in the sample.

[0030] A primary multi-way valve 5 is rotatably installed on the side of the control panel 11 near the digester 3. Multiple secondary multi-way valves 6 are also rotatably installed on the side of the control panel 11 near the digester 3. The outlets of the multiple secondary multi-way valves 6 are connected to the multiple outlets of the primary multi-way valve 5 through conduits. Four secondary multi-way valves 6 are installed on one side of the control panel 11. Each of the four secondary multi-way valves 6 can control the flow of different types of reagents into the primary multi-way valve 5, and then through the primary multi-way valve 5 into the photoelectric meter 9 for weighing.

[0031] The peristaltic pump 7 is fixedly connected to one side of the control panel 11. A connecting pipe is fixedly installed at the inlet end of the peristaltic pump 7, and the other end of the connecting pipe is fixedly connected to the outlet end of the photoelectric meter 9. The outlet end of the photoelectric meter 9 is connected to one of the outlets of the primary multi-way valve 5 through a conduit. When COD content in a sample needs to be detected, one of the secondary multi-way valves 6 is opened first, and then the peristaltic pump 7 is started. When the peristaltic pump 7 is working, the air inside the connecting pipe is discharged, thereby creating a strong negative pressure inside the connecting pipe. Then, the sample inside the opened secondary multi-way valve 6 is introduced into the primary multi-way valve 5. The sample drawn into the primary multi-way valve 5 flows through the conduit to the photoelectric meter 9 until the sample weight inside the photoelectric meter 9 reaches the predetermined value. Then, the peristaltic pump 7 is reversed, allowing the sample inside the photoelectric meter 9 to flow through the primary multi-way valve 5 into the digester 3. The sample is heated by the digester 3, causing the chemical bonds in the sample to break, thereby achieving sample digestion. The COD content in the digested sample can then be accurately detected.

[0032] The ammonia nitrogen detection component, through the cooperation of the primary multi-port valve 5 and the secondary multi-port valve 6, allows the sample to be transferred into the component. The component then detects the content of ammonia nitrogen, total nitrogen, and total phosphorus in the sample. Opening the other three secondary multi-port valves 6 allows the sample, driven by the peristaltic pump 7, to first pass through the primary multi-port valve 5 into the photoelectric meter 9, and then through the photoelectric meter 9 into the ammonia nitrogen detection component. This enables accurate detection of the ammonia nitrogen, total phosphorus, and total nitrogen content in the sample. Within a single work cycle, multiple work units can be used to detect the COD, ammonia nitrogen, total nitrogen, and total phosphorus content of different or identical samples, reducing the steps, time, and effort required for sample detection and improving efficiency.

[0033] The ammonia nitrogen detection assembly includes a second digester 10. The second digester 10 is fixedly installed on the control panel 11 near the first digester 3. An inlet pipe connected to a primary multi-way valve 5 is fixedly installed at the inlet end of the second digester 10, and an outlet pipe is fixedly installed at the outlet end. After starting the peristaltic pump 7, the sample flows from three secondary multi-way valves 6 through the primary multi-way valve 5 into the conduit, and then into the photoelectric meter 9. When the sample weight reaches a predetermined value, the peristaltic pump 7 reverses its rotation, allowing the sample inside the photoelectric meter 9 to flow through the primary multi-way valve 5 into the inlet pipe, and then into the inner cavity of the second digester 10. The second digester 10 heats the sample, breaking the chemical bonds in the sample, thus digesting the sample. This allows for accurate detection of the ammonia nitrogen, total nitrogen, and total phosphorus content in the digested sample.

[0034] Digester 2 10 is externally equipped with two sets of photoelectric detection mechanisms. These two sets of photoelectric detection mechanisms can emit two sets of rays of different wavelengths, thereby obtaining different data on the ammonia nitrogen, total nitrogen and total phosphorus content in the sample.

[0035] An overflow bottle 8 is detachably installed on one side of the control panel 11. The end of the outlet pipe away from the outlet of the digester 10 and the water outlet of the peristaltic pump 7 are both fixedly connected to one end of the overflow bottle 8. After the sample has been tested by the digester 10, starting the peristaltic pump 7 will allow the sample inside the digester 10 to enter the overflow bottle 8, which is beneficial for the centralized collection of the tested sample.

[0036] A connecting pipe 4 is fixedly installed at the inlet end of the digester 3. The other end of the connecting pipe 4 is connected to a first-stage multi-way valve 5. An overflow bottle 2 is fixedly installed on one side of the control panel 11. A flow pipe 12 is fixedly installed at the outlet end of the digester 3. The end of the flow pipe 12 away from the digester 3 is fixedly connected to the end of the overflow bottle 2. After passing through the first-stage multi-way valve 5, the sample can enter the interior of the digester 3 through the connecting pipe 4 and be discharged into the interior of the overflow bottle 2 through the flow pipe 12. This facilitates the entry and exit of the sample and enables continuous sample detection.

[0037] In the above embodiment, after the sample enters the digester 3, it needs to remain in the digester 3. Then, the sample remaining in the digester 3 is heated by a heating device (this is prior art; for specific models, please refer to the patent application number 201610521072.X, which will not be described in detail here). The sample inside the digester 3 is digested by heating. However, since the sample generates a large amount of steam and heat energy after being heated inside the digester 3, the steam and heat energy can easily cause the flow tube 12 and the connecting tube 4 to expand and melt. When the flow tube 12 and the connecting tube 4 melt, the sample in the digester 3 will leak, which will adversely affect the sample detection.

[0038] Solenoid valves are installed in the inner cavities of both the connecting pipe 4 and the flow pipe 12. When the sample inside the photoelectric meter 9 enters the connecting pipe 4 through the first-stage multi-way valve 5 and then enters the digester 3 through the connecting pipe 4, the solenoid valves inside the connecting pipe 4 and the flow pipe 12 are energized. At this time, the connecting pipe 4, the digester 3, and the flow pipe 12 between the two solenoid valves form a sealed chamber. When the heating device heats the sample inside the digester 3, the water vapor generated by the sample will cause the outer walls of the connecting pipe 4 and the flow pipe 12 to expand, and continuously heat the connecting pipe 4 and the flow pipe 12.

[0039] Both the connecting pipe 4 and the flow pipe 12 are fixedly fitted with heat dissipation pipes 13. The two heat dissipation pipes 13 are located between the two solenoid valves. The heat from the water vapor inside the connecting pipe 4 and the flow pipe 12 is transferred to the heat dissipation pipes 13 through the connecting pipe 4 and the flow pipe 12. Since the heat dissipation pipes 13 are directly exposed to the air, when the air around the heat dissipation pipes 13 flows, it will quickly dissipate heat from the heat dissipation pipes 13. This allows the heat dissipation pipes 13 to continuously absorb the heat transferred from the connecting pipe 4 and the flow pipe 12, thereby achieving the purpose of dissipating heat from the connecting pipe 4 and the flow pipe 12 and preventing the connecting pipe 4 and the flow pipe 12 from melting after being heated, which could lead to sample leakage.

[0040] The heat sink 13 is made of copper, which allows the heat to be quickly transferred from the connecting pipe 4 and the flow pipe 12 to the heat sink 13. At the same time, the heat sink 13 itself can dissipate heat quickly, thus improving the heat absorption and dissipation efficiency of the heat sink 13.

[0041] Multiple heat sinks are fixedly installed in a ring on the outer wall of the heat pipe 13. The heat sinks can increase the area of ​​the outer wall of the heat pipe 13, increase the contact area between the heat pipe 13 and the air, and further accelerate the heat dissipation efficiency of the heat pipe 13.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
