High-temperature tunnel type electrothermal dynamic sintering furnace

Abstract

The invention relates to the technical field of electronic component production, specifically to a high-temperature tunnel type electrothermal dynamic sintering furnace. The high-temperature tunnel type electrothermal dynamic sintering furnace comprises a heat insulation wall body, a tunnel type muffle tank installed in the heat insulation wall body and a conveying mechanism, wherein a connectingrod is fixedly connected to the side wall of a heat insulation plate; the end part of the connecting rod slidably penetrates through the side wall of a heating furnace to reach out of the heating furnace, and is fixedly connected to a first electric telescopic rod; the first electric telescopic rod works under the control of a controller; an air inlet capable of being blocked is formed in the sidewall of the heating furnace; and a temperature sensor is arranged in the heating furnace. During heating by gas, a sealing plug is dragged by a second electric telescopic rod to move rightwards, anddue to the fact that air pressure at a chimney is lower than air pressure at the air inlet, air enters from the air inlet at the moment and heat on the first cooling fin is taken away, so on one hand,heat dissipation effect is achieved, and on the other hand, air entering the heating furnace can be preheated and an original air preheater is replaced.

Description

technical field [0001] The invention relates to the technical field of electronic component production, in particular to a high-temperature tunnel-type electrothermal dynamic sintering furnace. Background technique [0002] In the field of electronics, the base of many electronic components is sintered quartz glass. At present, the sintering equipment for this kind of work depends on imports. The structure of this kind of imported furnace is to install a transmission system composed of a conveyor belt, a transmission roller and a motor on the lower frame. A cavity is formed between the conveyor belt and the upper frame. A heating furnace formed by insulating materials and heating elements is arranged around the tank. [0003] When working, the base workpiece is buckled in the upper and lower graphite molds, enters the furnace cavity from the entrance, and passes through the tunnel muffle tank under the protection of nitrogen. Under high temperature conditions, the workpiec...

Problems solved by technology

During the working process of the current muffle tank, the heating element in it is generally heated by resistance wire. When encountering a power outage / power failure, the backup motor and battery will start, but the power required by the resistance wire is relatively large, and the battery and backup The diesel generator is not enough to support the operation of the resistance wire, resulting in the heat in the tunnel muffle tank not reaching the process standard, which affects the sintering quality and causes a large number of products to be scrapped
