Description

Muffle furnace composite structure

[ technical field ] A method for producing a semiconductor device

The utility model relates to a firing equipment technical field specifically indicates a muffle furnace integrated configuration.

[ background of the invention ]

The muffle furnace is a common heating device, and is also called an electric furnace, a resistance furnace, a muffle furnace and a muffle furnace. The hearth space of the muffle furnace is relatively small, and in ash content testing, a crucible is conventionally arranged in the hearth, only one layer can be arranged, and the upper space cannot be fully utilized.

In view of the above problems, the applicant has proposed a solution.

[ Utility model ] content

The utility model aims at overcoming the defects of the prior art and providing a muffle furnace combined structure.

In order to solve the technical problem, the utility model adopts the following technical scheme:

a muffle furnace combined structure comprises a muffle furnace body, a crucible tray and a tray frame; the hearth of the muffle furnace is of a rectangular structure with length, width and depth; the crucible tray comprises a tray surface for placing a crucible and tray feet arranged under the tray surface, at least one crucible tray is arranged on the tray frame, and the rest crucible trays are arranged on the crucible trays of the next layer by layer.

In a further improvement scheme, a plurality of placing grooves for placing crucibles are arranged on the disc surface of the crucible tray.

In a further improvement, the crucible trays are three, and the hearth of the muffle furnace is of a rectangular structure with the length of 25cm, the height of 16cm and the depth of 40 cm.

In a further improvement scheme, the tray frame comprises a frame body, and a limiting part used for limiting tray feet is arranged at the bottom of the frame body.

Compared with the prior art, the beneficial effects of the utility model are that: the utility model discloses with the furnace design of muffle furnace for having the rectangle structure, avoided furnace to construct the restriction to length width height, stack a plurality of crucible trays on the tray frame, push the tray frame to furnace in again, the multilayer stacks, make full use of furnace space has improved the efficiency of ash content test greatly.

The invention will be described in further detail with reference to the following detailed description and accompanying drawings:
