Abstract

The invention relates to a push-pull combination insulation device and a high-temperature vacuum sintering furnace. The push-pull combination insulation device comprises an insulating layer, an outercooling layer, a reinforcing layer and push-pull parts, and the insulating layer, the outer cooling layer, the reinforcing layer and the push-pull parts are arranged from inside to outside in sequence; the outer cooling layer is a jacket layer wrapped on the outer wall of the insulating layer, and the jacket layer is internally filled with cooling media; the upper end and the lower end of the jacket layer are provided with a cooling medium inflow port and a cooling medium outflow port separately, so that the cooling of the insulating layer is accelerated through contact between the jacket layer and the insulating layer; the reinforcing layer is arranged at the exterior of the cooling layer, and the insulating layer is fixedly connected to the outer cooling layer; the outer cooling layer isfixedly connected to the reinforcing layer, and the push-pull parts are fixedly arranged on the outer wall of the reinforcing layer, and are rolling wheels connected to the reinforcing layer throughsupports; and the rolling wheels are used for sliding assembly with a furnace body. According to the push-pull combination insulation device, by adopting the push-pull parts, the flexible removable assembly between the insulation device and the furnace body is achieved, and damage to a heat shield is avoided; and the outer cooling layer is arranged at the exterior of the insulating layer, so thatthe insulating layer is cooled from the exterior of the insulating layer, and the cooling rate of the insulating layer is accelerated.

Description

technical field [0001] The invention relates to the technical field of vacuum sintering furnaces, in particular to a push-pull combined heat preservation device and a high-temperature vacuum sintering furnace. Background technique [0002] In the existing sintering furnace, the internal insulation device uses a heat shield, and the heat shield is usually made of high-temperature-resistant molybdenum or tungsten materials. These materials are brittle materials and are easily damaged by collisions when the furnace body is assembled. The existing installation methods are all fixed inside the furnace body by bolts, which requires the heat shield to be installed inside the furnace body using an external lifting device or manually lifted, which is inconvenient to operate, time-consuming and labor-intensive. Contents of the invention [0003] It is necessary to propose a push-pull combined heat preservation device. [0004] It is also necessary to propose a high-temperature vacu...
