Problems solved by technology

[0002] The bell-type resistance furnace is mainly suitable for the high-temperature sintering field of electronic ceramics, magnetic materials and powder metallurgy. The bell-type furnace is also called the lifting furnace. From the perspective of the feeding method, it can be divided into two types: furnace base lifting or furnace lifting. Due to the heavy weight of the upper part of the furnace, if the hoisting of the furnace fails during the descent, the furnace will fall heavily, which will easily crush the furnace base, and the furnace will also shake during the descent, resulting in low safety performance.

Embodiment Construction

[0012] In order to deepen the understanding of the present invention, the present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments, which are only used to explain the present invention and do not limit the protection scope of the present invention.

[0013] Such as figure 1 As shown, the present invention is a safety protection device for a bell-type resistance furnace, which includes two guide rails 2 arranged outside the furnace body 1 of the resistance furnace, and two guide columns 4 are arranged on the furnace base 3 of the resistance furnace Each of the guide posts 4 corresponds to each of the guide rails 2 and is inserted into each of the guide rails 2. The furnace body 1 is positioned by the guide rails 2 and the guide posts in the process of descending. guide to avoid the body of furnace 1 from shaking and accidents, the safety protection device of the resistance furnace also includes a displacement...

Abstract

The invention discloses a safety protecting device of a bell-jar-type resistance furnace. The safety protecting device comprises two guide pipelines arranged on the outer side of a furnace body of the resistance furnace, and a displacement sensor arranged at the lower end of a support on the outer side of the resistance furnace, two guide columns are arranged on a furnace seat of the resistance furnace, correspond to the guide pipelines in a one-to-one manner and are inserted into the corresponding guide pipelines respectively, a movable supporting seat is arranged at each of two ends of the furnace seat of the resistance furnace and below the outer wall of each guide pipeline, and each movable supporting seat is controlled by a controller. When the resistance furnace descends, the displacement sensor transmits sensed signals to the controller, the controller enables each movable supporting seat to move towards two sides, and a spring is arranged above each movable supporting seat. The safety protecting device is simple in structure, convenient to operate, reasonable in use, safe and reliable, and capable of protecting the furnace seat from being smashed.

Description

technical field [0001] The invention relates to a bell-type resistance furnace, in particular to a safety protection device for a bell-type resistance furnace. Background technique [0002] The bell-type resistance furnace is mainly suitable for the high-temperature sintering field of electronic ceramics, magnetic materials and powder metallurgy. The bell-type furnace is also called the lifting furnace. From the perspective of the feeding method, it can be divided into two types: furnace base lifting or furnace lifting. Due to the heavy weight of the upper part of the furnace, if the hoisting of the furnace fails during the descent, the furnace will fall heavily, which will easily crush the furnace base, and the furnace will also shake during the descent, which has low safety performance. Contents of the invention [0003] In order to solve the above problems, the present invention provides a safety protection device for a bell-type resistance furnace that prev...
