TECHNICAL FIELD

[0001] The present application relates to the field of test detection equipment technology, and particularly relates to a high-efficiency muffle furnace. BACKGROUND

[0002] The muffle furnace is a box type general heating equipment, and is often used for heat treatment of test samples in test detection, such as quenching, tempering and annealing of small steel parts, and dissolving and sintering of metal materials. In order to better preserve heat, the inner cavity of the muffle furnace is narrow and long, and the test sample to be heated cannot be directly placed in the muffle furnace in the use process, and needs to be placed in a crucible and then placed in the muffle furnace for heating.

[0003] In the experiment process, the crucible is usually directly placed in the furnace by a crucible fork and the like, and when multiple experiments are simultaneously performed, the substances to be burned need to be repeatedly burned, for example, in the loss on ignition determination experiment of cement, the test sample is placed in the crucible, burned at a preset temperature for a preset time, and after the test sample is taken out and cooled and weighed, the repeated burning is performed until the constant weight.

[0004] However, in the use of the existing muffle furnace, the operator can only send the samples placed in the crucible into the furnace one by one by the crucible fork, and after the burning is completed, the operator needs to take out the crucible in the furnace one by one by means of the crucible fork, which is relatively inconvenient and needs to be improved.
