Background

The element content is one of the important detection indexes of products in the petrochemical industry, the detection samples are various in types and different in forms, mainly comprise liquid phase, gas phase and solid phase, and different sample introduction samples are subjected to sample introduction by matching a fluorescence method detector and a coulomb method detector with different sample introduction devices, so that the detection work of each element content is completed. The liquid sample injector can basically meet the requirements of most users because most samples are liquid phase, but the liquid sample injection mode also needs to be reserved for solid samples. On one hand, a liquid standard sample can be fed to calibrate the instrument, on the other hand, the liquid sample can be detected at any time, and detection of different phases can be rapidly switched by simple selection.

Most of the original sample injectors are single solid sample injectors or single liquid sample injectors. The sample injection detection of the solid sample cannot be realized by aiming at a single liquid sample injector. In addition, due to the conditions of sample combustion and the objective requirements of instruments, the size of the cracking tube is limited, so that the positions of a solid sample inlet and a liquid sample inlet of a sample injector matched with the cracking tube cannot be too far away. The existing solid-liquid integrated sample feeding device has the following problems: the switching is inconvenient; as solid-liquid integrated sample introduction, on one hand, the solid sample introduction boat is brought into the cracking tube when solid is made, and on the other hand, the sample introduction needle is pushed to push the liquid sample into the cracking tube when liquid sample introduction is carried out. In actual operation, the carrier is easily brought into the cracking tube by mistake, so that the sampling condition is influenced, and result errors are caused.

3. Still including sealed upper cover, the refrigeration room on be connected with sealed upper cover, the liquid sampling needle can be dismantled and connect on the refrigeration room to be located the top of sealed upper cover.

4. The sealing upper cover is made of stainless steel.

In order to enable the liquid sample inlet and the solid sample inlet to be close to each other, the sealing upper cover is changed into a stainless steel plate to reduce the occupied space, and meanwhile, the sealing device is corrosion-resistant and good in sealing effect. The compact sample introduction structure is convenient for sample introduction on one hand and meets the structural requirements of the cracking tube on the other hand. In addition, a control structure of a power-on demagnetizing type electromagnet is added, so that switching of solid-liquid sample introduction is realized. When a liquid sample is fed, the sample feeding boat does not act due to attraction of the electrified degaussing type electromagnet, so that the situation that the boat is brought into the cracking tube by misoperation is avoided, and the error of detection of the liquid sample is reduced.

The utility model has the advantages of: this device has realized the switching of solid-liquid advance kind, avoids the maloperation, reduces the error to sample detection, has improved the efficiency that detects.
