Abstract

The invention discloses a graphite plate type heater, and relates to the technical field of graphite heaters. The graphite plate type heater comprises a box body, wherein fixed electrifying devices are fixedly mounted on the upper and lower surfaces of the box body, protective gas devices are arranged on the left and right side surfaces of the box body, a sealing cover is fixedly mounted on the front surface of the box body, the box body comprises box side walls, an upper graphite plate is movably installed at the upper ends of the left and right surfaces in the box side walls, and a lower graphite plate is fixedly installed at the lower ends of the box side walls. According to the invention, the graphite pipe is changed into the graphite plate, the problem that the internal space of the graphite pipe heater is insufficient is solved, meanwhile, the graphite plate is easier to machine compared with the graphite pipe, the machining cost is low, the machining process is simple, an upperkeel frame and a lower keel frame are additionally arranged, the strength of the upper graphite plate and the lower graphite plate is improved through the upper keel frame and the lower keel frame, and heating termination and gas leakage caused by fracture of the upper graphite plate and the lower graphite plate due to overlarge internal pressure intensity are prevented.

Description

technical field [0001] The invention relates to a graphite heater, relates to the technical field of graphite heaters, in particular to a graphite plate heater. Background technique [0002] The graphite heater is to inject the sample into the heater quantitatively with the injector, and use graphite as the resistance heating element, and the temperature will rise rapidly after the power is turned on, so that the sample can be atomized. It consists of a heating power supply, a protective gas control system and a graphite furnace. Composition, an external power supply is applied to both ends of the graphite to supply energy to the atomizer, and the current passes through the graphite to generate a temperature of up to 3000 ° C, so that the measured element placed in the graphite becomes the ground state atomic vapor. There are following problems at prior art: [0003] 1. Most of the existing graphite heaters are tubular heaters. Because graphite itself is a brittle material,...
