Description

Technical Field

[0001] This application relates to the field of sample analysis, and in particular to an online TOC analyzer. Background Technology

[0002] The TOC online analyzer is a chemical composition detector based on spectral analysis. The light source emits a beam of light of a specific wavelength, which passes through a container of liquid containing the test reagent. The light after passing through the sample is received and analyzed by the spectrometer. The instrument calculates the concentration of a specific component in the sample based on the changes in the light signal.

[0003] When performing spectral analysis, the TOC online analyzer is extremely sensitive to stray light. If the door is not closed tightly, even by a small crack, ambient light will enter and severely interfere with the detection optical path, resulting in inaccurate and unreliable readings, which in turn affects the detection data. When the instrument is not working, users cannot quickly distinguish whether the door is closed, which will lead to repeated trial and error and affect efficiency. Utility Model Content

[0037] The following is in conjunction with the appendix Figures 1-7 This application will be described in further detail.

[0038] This application discloses an online TOC analyzer.

[0039] Reference Figures 1-4 A TOC online analyzer includes an instrument housing 1, a rotating door 11 rotatably mounted on the side wall of the instrument housing 1, and a sealing strip on the edge of the rotating door 11, so that the interior is sealed and opaque when the rotating door 11 is in contact with the instrument housing 1. A safety mechanism 2 is installed inside the instrument housing 1, and the rotating door 11 is used to trigger the safety mechanism 2. A warning light 3 is installed on the top of the instrument housing 1. A liquid pump 4 is fixedly connected to the inner wall of the instrument housing 1. A xenon lamp 5 is fixedly connected to the inner wall of the instrument housing 1. A liquid flow cell 6 is fixedly connected to the inner wall of the instrument housing 1. A spectrometer 7 is fixedly connected inside the instrument housing 1 for sample data analysis. A water inlet and a water outlet are fixedly connected to the side wall of the instrument housing 1 to facilitate sample transport. The safety mechanism 2 is used to control the circuit linkage inside the instrument housing 1 and the circuit linkage of the warning light 3.

[0040] A magnetic block 12 is fixedly connected to the side wall of the instrument housing 1, and another set of magnetic blocks 12 is fixedly connected to the side wall of the rotating door 11. The inner wall of the instrument housing 1 is fixedly connected to the other set of magnetic blocks 12. The magnetic block 12 located on the inner wall of the instrument housing 1 is recessed into the inner wall of the instrument housing 1, and the magnetic block 12 located on the side wall of the rotating door 11 protrudes from the side wall of the rotating door 11. Thus, when the magnetic blocks 12 on both sides are attracted, the rotating door 11 and the instrument housing 1 are in a closed state. The size and specifications of the magnetic blocks 12 control the magnetic force of the magnetic blocks 12 to a level where the operator can control the rotation of the rotating door 11, but when in the attracted state, the rotating door 11 remains stationary. The rotating door 11 and the instrument housing 1 are connected by the mutual attraction of the two sets of magnetic blocks 12.

[0041] The staff connects the pipe to the inlet and outlet of the instrument housing 1 to transport the sample. Then, when the sample passes through the liquid flow cell 6, the spectrum is irradiated into the spectrometer 7 by the xenon lamp 5 to analyze the sample. When the rotating door 11 is not in contact with the instrument housing 1, the warning light 3 will be powered on to warn the staff. When the rotating door 11 is completely closed with the instrument housing 1, the circuit of the warning light 3 will be disconnected to detect whether the rotating door 11 is completely closed.

[0042] Reference Figures 3-6Safety mechanism 2 includes a trigger plate 21 fixedly connected to the side wall of rotating door 11. The trigger plate 21 is made of metal. A square tube 22 is fixed to the inner wall of instrument housing 1 by screws. A light power supply component is provided on the top of the square tube 22. A sliding component is provided on the inner wall of the square tube 22. The light power supply component includes a fixing member 23 fixedly connected to the top of the square tube 22. A wire 24 is provided on the top of the fixing member 23. The top of the fixing member 23 is fixedly connected to the wire 24. The wire 24 is connected to the detection equipment inside the instrument housing 1 to supply power to the equipment. A positioning member 25 is slidably connected to the outer wall of the wire 24. The positioning member 25 is fixedly connected to the inner wall of the instrument housing 1. A connecting piece 26 is provided at the bottom connection end of the wire 24. The bottom connection end of the wire 24 is fixedly connected to the top of the connecting piece 26. The connecting piece 26 is made of metal and is conductive.

[0043] Connecting piece 26 is fixedly inserted through the top of square tube 22. A non-penetrating horizontal groove is provided on the side wall of connecting piece 26. Connecting piece 26 is snapped into the top of square tube 22 through the groove. The top horizontal surface of instrument housing 1 is fixedly connected to the bottom mounting end of warning light 3.

[0044] When the rotating door 11 is fully closed, the trigger plate 21 will attract the sliding component, thereby transmitting power to the connecting plate 26. The connecting plate 26 will then transmit power to the internal detection equipment via the wire 24, allowing normal sample detection to proceed. When the rotating door 11 is not closed in contact with the instrument housing 1, the trigger plate 21 cannot attract the sliding component. In this case, the sliding component will be attracted away from the trigger plate 21 by the magnetic force on the other side, thus activating the circuit of the warning light 3, supplying power to the warning light 3 and alerting that the rotating door 11 is not closed.

[0045] Reference Figures 5-7 The sliding assembly includes a square block 27 slidably connected inside the square cylinder 22. A magnetic piece 28 is provided in the middle of the square block 27. The side wall of the middle of the square block 27 is fixedly connected to the side of the magnetic piece 28 near the square block 27. The magnetic piece 28 is magnetic. An installation groove is provided in the middle of the square block 27. The magnetic piece 28 is placed in the installation groove, thereby fixing the magnetic piece 28 through the square block 27. The side wall of the magnetic piece 28 is flush with the side wall of the square block 27, thereby avoiding interference between the square block 27 and the magnetic piece 28 when the magnetic piece 28 is in contact with the trigger piece 21. A connecting cylinder 29 is provided on the side wall of the square block 27 away from the magnetic piece 28. The connecting cylinder 29 is fixedly connected to the square block 27. The outer wall of the connecting cylinder 29 is in contact with the inner wall of the square cylinder 22. A connecting assembly is provided inside the connecting cylinder 29.

[0046] When the rotating door 11 is in contact with the instrument housing 1, the trigger plate 21 will attract the magnetic plate 28 to move towards the trigger plate 21, thereby causing the magnetic plate 28 to drive the square block 27 to move horizontally, and the square block 27 to drive the connecting cylinder 29 to move horizontally.

[0047] Reference Figures 4-7 The connecting assembly includes a connecting block 210 fixedly inserted through the bottom of the inner wall of the connecting cylinder 29. The bottom of the connecting block 210 is flush with the bottom of the connecting cylinder 29. A connecting block 211 is provided at the bottom of the connecting block 210. The connecting block 210 and the connecting block 211 are fixedly connected. The connecting block 211 is slidably connected to the bottom of the square cylinder 22. A wire 212 is provided at the bottom of the connecting block 211. The bottom of the connecting block 211 and the top connection end of the wire 212 are fixedly connected. The outer protective layer of the wire 212 is made of rubber tubing, so as to ensure insulation and adapt to the movement of the connecting block 211. Wire 212 is fixedly connected to the side wall of the instrument housing 1, thereby transmitting external power to connector block 211 through wire 212. Connector block 211 is connected to connector block 1 210 in circuit. Wire 3 213 is fixedly connected to the top connection end of connector block 1 210, and wire 4 214 is fixedly connected to the top connection end of connector block 1 210. Thus, power can be transmitted to wire 3 213 and wire 4 214 simultaneously through connector block 1 210. Connector piece 215 is fixedly connected to the end of wire 3 213 away from connector block 1 210 through an installation plug-in. Connector piece 215 is made of metal and is conductive.

[0048] When the connecting cylinder 29 moves horizontally, it will drive the connecting block 1 210 to move horizontally, which in turn will drive the connecting block 211 to move horizontally, the connecting block 210 to drive the wire 3 213 to move horizontally, and the connecting block 210 to drive the wire 4 214 to move horizontally. The connecting cylinder 29 will also drive the connecting piece 215 to move horizontally synchronously, and the connecting cylinder 29 will drive the connecting piece 3 216 and the positioning frame 217 to move horizontally. At this time, the connecting piece 215 and the connecting piece 1 26 are in contact, and the wire 3 213 transmits power to the connecting piece 1 26 through the connecting piece 215, so that the connecting piece 1 26 transmits power to the internal detection equipment through the wire 1 24, thereby completing the power supply.

[0049] Reference Figures 5-7One end of wire 214, away from connecting block 210, is fixedly inserted through the side wall of connecting cylinder 29, thus enabling the power from wire 213 to be ultimately transmitted to connecting piece 215. The top of connecting piece 215 is at the same height as the top of the outer wall of connecting cylinder 29. The end of wire 214 away from connecting block 210 is fixedly connected to connecting piece 216 via an installation plug. Connecting piece 216 is made of metal and is conductive. A positioning frame 217 is fixedly connected to the outer wall of connecting piece 216 by bolts, and the positioning frame 217 fixes the connecting piece 216. A connecting frame 218 is fixedly connected to the inner wall of square cylinder 22 by welding. The side of positioning frame 217 away from connecting cylinder 29 is connected to the connecting piece 215. The frame 218 is fitted together, and a magnetic absorbing piece 219 is fixedly connected to the middle of the frame 218 through a groove. The magnetic absorbing piece 219 is magnetic. The end of the connecting piece 3 216 away from the wire 4 214 is fitted to the side wall of the magnetic absorbing piece 219. The end of the magnetic absorbing piece 219 away from the connecting piece 3 216 is fixedly connected to the connecting wire 220 through an installation plug. The outer wall of the connecting wire 220 is slidably connected to the positioning piece 221. The end of the positioning piece 221 away from the connecting wire 220 is fixedly connected to the inner wall of the instrument housing 1. The connecting wire 220 is fixedly passed through the top of the inner wall of the instrument housing 1. The connecting wire 220 is fixedly connected to the warning light 3 and supplies power to the warning light 3 through the connecting wire 220.

[0050] The magnetic field of magnetic piece 219 is less than that of magnetic piece 28. When magnetic piece 28 is attracted and moved by trigger piece 21, magnetic piece 219 will not be able to restrict the horizontal movement of connecting cylinder 29. When magnetic piece 28 is not attracted by trigger piece 21, magnetic piece 219 will attract connecting piece 3 216, thereby causing connecting cylinder 29 to drive connecting piece 3 216 to move horizontally towards magnetic piece 219, so that connecting piece 3 216 and magnetic piece 219 are in contact. At this time, the power supply of connecting piece 215 to connecting piece 1 26 will be disconnected. Wire 4 214 will transmit power through connecting piece 3 216 to connecting wire 220 through magnetic piece 219, thereby transmitting power to warning light 3 through connecting wire 220, so that warning light 3 will emit light to remind staff that rotating door 11 has not been fully closed.

[0051] The implementation principle of an online TOC analyzer according to an embodiment of this application is as follows:

[0052] The staff connects the pipe to the water inlet and outlet on the outer wall of the instrument housing 1 to transport the sample. Then, when the sample passes through the liquid flow cell 6, the spectrum is irradiated into the spectrometer 7 by the xenon lamp 5, so that the sample can be analyzed.

[0053] When the rotating door 11 is fully closed, the trigger plate 21 will attract the sliding component, thereby transmitting power to the connecting plate 26. The connecting plate 26 will then transmit power to the internal detection equipment via the wire 24, allowing normal sample detection to proceed. When the rotating door 11 is not closed in contact with the instrument housing 1, the trigger plate 21 cannot attract the sliding component. In this case, the sliding component will be attracted away from the trigger plate 21 by the magnetic force on the other side, thus activating the circuit of the warning light 3, supplying power to the warning light 3 and alerting that the rotating door 11 is not closed.

[0054] When the rotating door 11 is in contact with the instrument housing 1, the trigger plate 21 will attract the magnetic suction plate 28 to move towards the trigger plate 21, thereby causing the magnetic suction plate 28 to drive the square block 27 to move horizontally. The square block 27 drives the connecting cylinder 29 to move horizontally. When the connecting cylinder 29 moves horizontally, it will drive the connecting plate 215 to move horizontally in sync. At this time, the connecting plate 215 and the connecting plate 26 are in contact. The wire 3 213 transmits power to the connecting plate 26 through the connecting plate 215, thereby enabling the connecting plate 26 to transmit power to the internal testing equipment through the wire 24, thus completing the power supply.

[0055] When magnetic plate 1 28 is not attracted by trigger plate 21, magnetic plate 219 will attract connecting plate 3 216, causing connecting cylinder 29 to move connecting plate 3 216 horizontally towards magnetic plate 219, so that connecting plate 3 216 and magnetic plate 219 are in contact. At this time, the power supply from connecting plate 215 to connecting plate 1 26 will be disconnected, and wire 4 214 will transmit power through connecting plate 3 216 to connecting wire 220 through magnetic plate 219, so that power is transmitted to warning light 3 through connecting wire 220, so that warning light 3 emits light to remind staff that the rotating door 11 has not been fully closed.

[0056] The above are merely optional embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
