Description

Technical Field

[0001] This utility model relates to the field of atomic fluorescence spectrophotometer technology, specifically to an atomic fluorescence spectrophotometer draining device with a purification structure. Background Technology

[0002] An atomic fluorescence spectrometer is an instrument used to measure the concentration of a specific element in a sample. Its working principle is based on atomic fluorescence spectroscopy. When a light source of a specific wavelength illuminates a sample in an atomizer, the atoms in the sample are excited to a high energy level, and then emit fluorescence of a specific wavelength when they return to a low energy level. The fluorescence intensity is directly proportional to the concentration of that element in the sample. By measuring the fluorescence intensity and combining it with a known standard curve or elemental characteristics, the content of the element in the sample can be determined.

[0003] During the measurement process, the atoms that are excited into a gaseous state eventually form a liquid and are discharged. However, during the discharge of the liquid, impurities in the liquid need to be separated before it can be discharged. Direct discharge would pollute the environment.

[0004] Therefore, this utility model discloses a liquid discharge device for an atomic fluorescence spectrometer with a purification structure. Utility Model Content

[0005] To achieve the above technical solution, this utility model is implemented through the following technical solution: an atomic fluorescence spectrometer draining device with a purification structure, comprising: a draining tank, a filter tank, and a sedimentation tank;

[0006] The upper end of the draining tank is detachably connected to the cover, and a straight rod is set in the middle of the draining tank to connect to the sedimentation tank. The draining tank is symmetrically opened on both sides to install the filter tank, and a draining funnel is set on the inner wall of the installation groove.

[0007] The upper end of the sedimentation tank is equipped with an array of siphon tubes; the siphon tube is a U-shaped tube with an inverted small U-shaped tube at one end. The sedimentation tank continuously collects liquid, and the liquid settles inside the sedimentation tank. When the liquid level is higher than the siphon tube and the liquid fills the small U-shaped tube, the siphon tube will siphon and discharge the supernatant after sedimentation.

[0008] The filter barrel is provided with an arc-shaped plate with the same shape as the mounting groove. The filter barrel is provided with a filter layer inside. After the arc-shaped plate is inserted into the mounting groove, the filter barrel is located directly below one end of the siphon tube, and the lower end of the filter barrel is directly opposite the upper end of the drain funnel.

[0009] Furthermore, a conduit is provided at the upper middle part of the cover to connect to a photometer, and a filter screen is provided at the lower middle part of the cover to filter the liquid once.

[0010] Furthermore, solenoid valves are symmetrically arranged at the lower end of the sedimentation tank, and the discharge and collection of sediment in the sedimentation tank are controlled by controlling the opening and closing of the solenoid valves.

[0011] Furthermore, the siphon tube has one end located inside the sedimentation tank and the other end located at the top of the filter tank, and the height of the siphon tube opening at the top of the filter tank is 3-5 cm lower than that of the siphon tube located inside the sedimentation tank.

[0012] Furthermore, a drain pipe is provided at the lower middle part of the drain tank;

[0013] The beneficial effects of the utility model are:

[0014] This utility model discloses a liquid discharge device for an atomic fluorescence spectrometer with a purification structure, comprising: a discharge tank, a filter bucket, and a sedimentation bucket; the liquid generated inside the spectrometer is collected into the sedimentation bucket through a conduit on the cover, and the liquid is filtered once by the filter screen during the collection process;

[0015] The liquid entering the sedimentation tank settles inside. When the liquid level is higher than the siphon tube and the liquid fills the small U-shaped tube, the siphon tube will siphon and discharge the supernatant after sedimentation. The liquid discharged through the siphon tube will be filtered twice by the filter layer inside the filter tank before being discharged from the bottom of the drain tank.

[0016] In this invention, impurities in the liquid produced by the photometer are separated through two filtrations and one sedimentation, thus avoiding direct discharge that could pollute the environment. Attached Figure Description
