Furnace mouth bottom automatic protection device

Abstract

The invention discloses a furnace mouth bottom automatic protection device which comprises a furnace door opening; a furnace door body is arranged on the upper side of the furnace door opening; a furnace mouth bottom table is arranged on the lower side of the furnace door opening; a guide rail is fixedly connected to the outer side of the furnace mouth bottom table; a skip car body is arranged on the guide rail in a sliding mode; the skip car body is jointly composed of a skip car platform and a skip car chassis; the upper surface of the skip car platform is flush with the upper surface of the furnace opening bottom table; connecting wheels on the lower side of the skip car chassis are correspondingly arranged on guide rails; connecting rods are rotatably connected to the two sides of the skip car chassis; and the other ends of the connecting rods are rotationally connected to the left and right sides of the front surface of the furnace door body. In the furnace mouth bottom automatic protection device, the skip car obtains a horizontal reciprocating motion traction force through the lifting power of the furnace door; the skip car and the furnace door realize position interlocking and motion synchronization through the left and right connecting rods; the furnace door is opened to finish automatic protection of the skip car to the bottom of the furnace mouth; and the reliable sealing time of the furnace door and the bottom of the furnace mouth is prolonged.

Description

technical field [0001] The invention relates to the field of industrial furnaces, in particular to an automatic protection device for the bottom of a furnace mouth. Background technique [0002] The technological progress of industrial furnaces plays a very important role in the development of the industry, and the sealing problem of the furnace door and furnace mouth of industrial furnaces, especially high-temperature heating gas furnaces, has always been a difficult problem in the industry. [0003] The bottom of the furnace mouth of industrial furnaces, especially the bottom of the furnace mouth at the discharge port, is generally made of refractory castables. The bottom of the furnace mouth is prone to wear and bumps when feeding and discharging materials, resulting in damage to the sealing surface of the bottom of the furnace mouth. Once the seal is not tight, there will be a phenomenon of air leakage and fire leakage, which will quickly cause the sealing material of th...

Problems solved by technology

[0003] The bottom of the furnace mouth of industrial furnaces, especially the bottom of the furnace mouth at the discharge port, is generally made of refractory castables. The bottom of the furnace mouth is prone to wear and bumps when feeding and discharging materials, resulting in damage to the sealing surface of the bottom of the furnace mouth. Once the seal is not tight, there will be air leakage and fire leakage, which will soon cause the sealing material of the furnace door and the furnace mouth to burn out and fail, resulting in large economic losses.
