Photoelectric direct-reading spectrometer

Abstract

The invention belongs to the technical field of spectral decomposition, and specifically relates to a photoelectric direct-reading spectrometer. The photoelectric direct-reading spectrometer comprisesa main frame body, a partition plate, a spectrometer body, a rotary heating mechanism, a heat preservation mechanism and a stirring mechanism; the partition plate is fixedly connected to the two sides of the upper end of inside of the main frame body; the partition plate is arc-shaped, the lower end of the interior of the partition plate is filled with an asbestos layer, and the rotary heating mechanism is arranged below the partition plate; the spectrometer body is fixedly installed at the upper end of the asbestos layer; the rotary heating mechanism comprises an air jet hole, a rotary furnace, a No.1 flintstone, a No.2 flintstone, a connecting rod, a motor, a bevel gear, a No.1 straight gear and a No.1 rotating column; and the air jet hole is fixedly installed at the lower surface of the outer end of the partition plate, and the rotary furnace is arranged below the air jet hole. The photoelectric direct-reading spectrometer provided by the invention is mainly used for solving the problem that a large amount of heat energy waste and fuel waste are caused due to the fact that the temperature of a dissolving furnace in the prior art is kept consistent when different metals are dissolved, and the temperature cannot be freely switched according to the melting temperature of the metals.

Description

technical field [0001] The invention belongs to the technical field of spectral decomposition, in particular to a photoelectric direct reading spectrometer. Background technique [0002] Photoelectric direct-reading spectroscopic analysis uses the high temperature of the arc (or spark) to directly vaporize and excite the elements in the sample from the solid state to emit the characteristic wavelengths of each element. After splitting the light with a grating, it becomes a spectrum arranged by wavelength. The characteristic spectral lines pass through the exit slit and enter the respective photomultiplier tubes. The optical signal becomes an electrical signal. The electrical signal is integrated and converted by the control and measurement system of the instrument, and then processed by the computer and printed out. The percentage content of elements, different metals are often dissolved in today's metal melting furnaces, and the biggest difference in the dissolution of diff...
