Opening and closing device of furnace door of heating furnace

Abstract

The invention provides an opening and closing device of a furnace door of a heating furnace, and belongs to the technical field of machinery. The problem that the stability is poor in the prior art issolved. According to the opening and closing device of the furnace door of the heating furnace, the heating furnace comprises a furnace body internally provided with a cavity, a furnace opening communicated with the inner cavity of the furnace body is arranged in the side part of the furnace body, and a furnace door capable of opening and closing the furnace opening is connected to the furnace body; the opening and closing device is positioned between the furnace body and the furnace door, and comprises a driving part, a transmission rod, a rolling wheel and a guide part, the driving part isfixedly connected to the furnace body, the lower end of the transmission rod is connected with the driving part, the upper end of the transmission rod is hinged to the lower part of the furnace door,and the rolling wheel is connected to the upper part of the furnace door and is embedded in the guide part. The opening and closing device of the furnace door of the heating furnace is high in stability.

Description

technical field [0001] The invention belongs to the technical field of machinery and relates to an opening and closing device for a furnace door of a heating furnace. Background technique [0002] The heating furnace includes a furnace body with a cavity inside. The inside of the furnace body is a cavity. The side of the furnace body has a furnace mouth communicating with the inner cavity. A furnace door is connected to the furnace body, and the furnace door can open and close the furnace mouth. [0003] One side of the existing furnace door is usually hinged on the furnace body, which causes the furnace door to take up too much space when opening and closing the furnace door. At the same time, since the rapid airflow generated during the opening and closing process of the furnace door will enter the furnace body, the temperature in the heating furnace will be affected, which will eventually affect its heating stability. Contents of the invention [0004] The object of th...
