Sintering furnace with heat recovery function and uniform heating capability

Abstract

The invention relates to a sintering furnace with a heat recovery function and uniform heating capability. The sintering furnace comprises a sintering chamber, a conveyor belt and a base, as well as arecovery mechanism and a feeding mechanism; the feeding mechanism comprises a feeding groove, a discharging pipe, a rotating cylinder, an annular track, an annular groove, a driving assembly and a discharging port; the recovery mechanism comprises a heat absorption box, a third heat conduction pipe, a first heat conduction pipe, a heat storage box, an air pump and at least two fourth heat conduction pipes; and the driving assembly comprises a motor, a gear and an annular rack. In the sintering furnace with the heat recovery function and the uniform heating capability, part of the heat on workpieces can be recovered through the recovery mechanism, so that the recovery and utilization of the heat are realized, and the energy-saving performance of the sintering furnace is improved; and the workpieces can be uniformly spread on a conveying belt through the feeding mechanism, so that the spatial heating uniformity is improved, and the sintering quality of the sintering furnace is improved.

Description

technical field [0001] The invention relates to the field of new material equipment, in particular to a uniformly heated sintering furnace with heat recovery function. Background technique [0002] The sintering furnace refers to the special equipment for obtaining the required physical and mechanical properties and microstructure of the powder compact through sintering. The sintering furnace is used to dry the slurry on the silicon wafer, remove the organic components in the slurry, and complete the aluminum back field and grid wire sintering. Sintering furnaces are widely used in the production of new materials. [0003] In the process of using the sintering furnace in the prior art, the workpiece needs to be cooled rapidly after sintering. During this process, the residual heat on the workpiece is directly dissipated, resulting in energy loss and reducing the energy-saving performance of the sintering furnace. Not only that In the sintering furnace of the prior art, if ...

Problems solved by technology

[0003] In the process of using the sintering furnace in the prior art, the workpiece needs to be cooled rapidly after sintering. During this process, the residual heat on the workpiece is directly dissipated, resulting in energy loss and reducing the energy-saving performance of the sintering furnace. Not only that , in the sintering furnace of the prior art, in the process of workpiece feeding, if a large number of workpieces are piled up together, it will cause uneven heating of the workpieces and reduce the sintering effect of the sintering furnace
