Abstract

A furnace door sealing device, comprising a furnace door cylinder and connected to a furnace door opening and closing lever through a cylinder piston rod, the furnace door opening and closing lever and a furnace door cover plate with a sealing plate, the furnace door opening and closing lever and a furnace door opening and closing lever The furnace door cover plate is connected by a mounting shaft, and can rotate in two mutually orthogonal directions. In the present invention, two rotating shafts whose axes are perpendicular to each other are arranged between the furnace door cover plate and the opening and closing lever, so that the furnace door cover plate can automatically adjust the orientation of the furnace door cover plate when it contacts the end surface of the furnace tube, ensuring that the furnace door cover plate Reliable contact with the furnace door to ensure its sealing performance. At the same time, the present invention arranges a gas collection cover outside the furnace door, which can collect the leaked gas and conduct concentration detection, which solves the problem of manual inspection due to the uncertain location of gas leakage.

Description

Technical field

[0001] The invention relates to a furnace door sealing device, in particular to a metal powder reduction furnace door sealing device. Background technique

[0002] Reducing gas is often used in metal powder reduction production. For example, hydrogen is used as a reducing medium to reduce the metal oxide powder to metal powder through a reduction reaction at a certain temperature. During the reduction, the furnace tube is filled with a certain pressure of reducing gas, which requires the furnace door at both ends of the furnace tube to have good sealing performance. Otherwise, it will not only increase the consumption of reducing gas, but also cause incomplete reduction and affect product quality. In severe cases, gas explosion may occur. Therefore, ensuring the sealing performance of the furnace door is one of the important factors to ensure safe production and product quality.

[0003] In order to easily realize the furnace door seal, a soft seal is usually adop...
