Movable split vertical tube type atmosphere furnace device

Abstract

The invention relates to a movable split vertical tube type atmosphere furnace device which comprises a heating furnace in a split type structure; the heating furnace is hinged on a lifting frame; a furnace tube is vertically arranged in the center of the heating furnace; the cavity of the furnace tube is in a step type with a large upper end and a small lower end; and a sample pan is arranged ina step position of the cavity of the furnace tube. The heating furnace can be moved vertically and horizontally and can adapt to different furnace tubes, thus, the application range is extended, and the application flexibility is increased. Due to the adoption of split type operation of the heating furnace, the heating furnace can be firstly heated to a certain preset temperature and then moved into the furnace tube, and materials are heated from the preset temperature, which avoids heating the materials from a room temperature to the preset temperature and is more beneficial to studying suchreactions. Due to the adoption of split type operation of a furnace door, the temperature of the materials in the furnace tube is reduced quickly, and thus, the time is saved. The movable split vertical tube type atmosphere furnace device is beneficial to full reaction of solid materials and atmosphere in the furnace tube, and overcomes the disadvantage that the reaction of materials and air flowof a traditional tube type furnace is insufficient.

Description

technical field [0001] The invention relates to a tube type furnace, in particular to a movable split vertical tube type atmosphere furnace device. Background technique [0002] In daily industrial production and scientific research activities, it is often necessary to use tube heating furnaces to heat materials and make them come into contact with a specific atmosphere for chemical reactions. Conventional tube furnace structure, no matter it is placed horizontally or vertically, the furnace tube is placed in a fixed furnace. This conventional structural design is simple to operate, but it is not suitable for the study of materials, especially solid materials and gas flow, and the contact between gas and reaction materials is greatly restricted, which affects the rapid progress of chemical reactions; In addition, sometimes the material needs to avoid the heating section from room temperature to a certain predetermined temperature, but directly start the heating reaction fro...

Problems solved by technology

This conventional structural design is simple to operate, but it is not suitable for the study of materials, especially solid materials and gas flow, and the contact between gas and reaction materials is greatly restricted, which affects the rapid progress of chemical reactions; In addition, sometimes the material needs to avoid the heating section from room temperature to a certain predetermined temperature, but directly start the heating reaction from a certain predetermined temperature. At this time, the above-mentioned conventionally designed heating furnace cannot well realize this requirement.

Moreover, in the cooling process of the existing tube furnace after the heating is stopped, because the furnace tube is fixed in the furnace with a large thermal inertia, it is often impossible to achieve rapid cooling unless other auxiliary cooling systems are added, but this increases the system temperature. The complexity and cost of using
