Abstract
Description

[0003] The existing technical solutions are single-layer continuous heating furnace and single-layer partition heating furnace.

[0032] In a specific embodiment, referring to Figure 1 and Figure 2A multi-temperature zone isolation heating furnace includes: a first furnace body 30, wherein the first furnace body 30 has a first furnace cavity 31, the first furnace cavity 31 is a first temperature zone, and the first furnace cavity 31 has a first port and a second port that can be opened and closed; a second furnace body 40 located above the first furnace body 30, wherein the second furnace body 40 has a second furnace cavity 41, the second furnace cavity 41 is a second temperature zone, and the second furnace cavity 41 has a third port and a fourth port that can be opened and closed; a third furnace body 50 located above the second furnace body 40, wherein the third furnace body 50 has a third furnace cavity 51, the third furnace cavity 51 is a third temperature zone, and the third furnace cavity 51 has a fifth port and a sixth port that can be opened and closed; and a first lifting module 10 is included, wherein the first lifting module 10 is used to transfer materials among the first port, the third port, and the fifth port; and a second lifting module 20 is included, wherein the second lifting module 20 is used to transfer materials among the second port, the fourth port, and the sixth port. Specifically, a first outer insulation door 32 is installed at the first port, a second outer insulation door 35 is installed at the second port, a third outer insulation door 42 is installed at the third port, a fourth outer insulation door 45 is installed at the fourth port, a fifth outer insulation door 52 is installed at the fifth port, and a sixth outer insulation door 55 is installed at the sixth port. Optionally, the first furnace body 30, the second furnace body 40, and the third furnace body 50 have the same or similar lengths, and the first port, the third port, and the fifth port are approximately located in the same plane. In this solution, the first port, the third port, and the fifth port can share a first lifting module 10, and the second port, the fourth port, and the sixth port can share a second lifting module 20, which not only achieves effective isolation of adjacent temperature zones, but also simplifies the equipment structure and reduces the footprint of the equipment.
