AI Technical Summary

Technical Problem

The feeding device of existing graphite furnaces is complicated and it is not convenient to extract the material rack in the graphite furnace, which causes the product heated in the graphite furnace to be unable to fully contact and be heated with the gases in the graphite furnace.

Method used

A graphite furnace feeding device is designed, including a bracket seat, guide rail, push frame, stepper motor, cylinder assembly and screw assembly. Through the synergy of these components, the stable transport of the graphite seat rack and the rotation of the material rack are achieved, ensuring that the ceramic fiber material on the surface of the graphite cylinder reacts uniformly and is heated with the gases entering the graphite furnace.

Benefits of technology

The simple and effective performance of feeding and discharge of graphite furnace is achieved, the stable transportation of the graphite holder and the uniform rotation of the material holder are ensured, and the reaction and heating uniformity of the ceramic fiber material on the surface of the graphite cylinder and the gas in the graphite furnace are improved.

Abstract

The present invention discloses a graphite furnace feeding device and method, including a bracket seat, wherein a guide rail 1 is installed on the surface of the bracket seat along the length direction thereof, guide rails 2 and 3 are installed on both sides of the guide rail 1 through the bracket seat, a rack plate is arranged on one side of the guide rail 1 through a fixed frame along the length direction thereof, a push frame is slidably installed on the guide rail 1, the top of the push frame is open, a push block is provided at the right end of the push frame, and a stepping motor is installed at the left end of the push frame. Beneficial effect: the graphite bracket can be stably transported into the graphite furnace, and at the same time, the material rack on the graphite bracket is ensured to rotate on the graphite bracket under the action of a rotating mechanism, so that ceramic fiber material is wound on the graphite barrel, and the rotation of the material shaft is driven by the rotating mechanism. During the rotation of the material shaft, the ceramic fiber material on the surface of the graphite barrel and the gas introduced into the graphite furnace can react more evenly, and the heating is also more even.
