Non-contact magnetic sampling device

Abstract

The invention discloses a non-contact magnetic sample injection device. The device comprises a machine body, a magnetic mechanism, a driving motor, a sample feeding mechanism and a control panel; thedriving motor is fixed to one end of the machine body, the magnetic mechanism is slidably connected to the interior of the machine body, the sample feeding mechanism is arranged above the magnetic mechanism, and the control panel is connected to the outer portion of the machine body at one end of the driving motor; the sample feeding mechanism comprises a magnetic cylinder, a sample feeding porcelain boat, a fixed rod and a supporting rod; the machine body comprises a fixed guide rail, a propelling screw rod and a fixed frame; the magnetic mechanism comprises an electromagnet fixing sleeve andan electromagnet block. The magnetic force between the electromagnet block and the magnetic cylinder can be effectively adjusted according to the weight of a sample; the magnetic mechanism pushes themagnetic cylinder and drives the sample introduction porcelain boat to carry out non-contact sample feeding in the high-temperature pipe, so the phenomena of gas leakage and temperature loss caused by traditional contact sample feeding in a sealed and protective gas high-temperature environment are avoided, and the influence of a traditional sample feeding mode on sample test data is fundamentally eliminated.

Description

technical field [0001] The invention relates to the field of sampling systems, in particular to a non-contact magnetic sampling device. Background technique [0002] Samples need high-temperature pre-treatment before testing and testing. Generally, high-temperature pre-treatment requires manual or machine use of a sampling rod to introduce the sample into the processing area. Since the material of the sampling rod is generally quartz glass or high-temperature-resistant alloy wire, and the sampling rod has Certain size restrictions, so the sample delivery rod needs to drive the sample delivery through contact push during the sample delivery process, so in the sample delivery process, it is very easy to cause leakage in the high temperature environment with sealing and protective gas The loss of gas and temperature leads to incomplete sample processing, which leads to deviations in the later inspection results of samples. At the same time, this manual method of pushing samples...

[0002] Samples need high-temperature pre-treatment before testing and testing. Generally, high-temperature pre-treatment requires manual or machine use of a sampling rod to introduce the sample into the processing area. Since the material of the sampling rod is generally quartz glass or high-temperature-resistant alloy wire, and the sampling rod has Certain size restrictions, so the sample delivery rod needs to drive the sample delivery through contact push during the sample delivery process, so in the sample delivery process, it is very easy to cause leakage in the high temperature environment with sealing and protective gas The loss of gas and temperature leads to incomplete sample processing, which leads to deviations in the later inspection results of samples. At the same time, this manual method of pushing samples to send samples is inconvenient to operate, and it is impossible to adjust the distance of a single injection and the number of injections. Precise control with injection time interval, poor applicability
