Industrial furnace door sealing device simple in operability

Abstract

The invention relates to the technical field of furnace door sealing devices and discloses an industrial furnace door sealing device simple in operability. The industrial furnace door sealing device simple in operability comprises a base, wherein a furnace body and lifting columns are fixedly mounted on the top end of the base, a top plate is fixedly mounted at the top ends of two adjacent lifting columns, first threaded rods are movably mounted in the lifting columns respectively, and a first moving block is in threaded connection to the outer side of each first threaded rod. By using the industrial furnace door sealing device simple in operability, when a third rotating rod rotates, a second threaded rod and a third threaded rod can be driven to rotate together, so that a second moving block and a third moving block can move oppositely; and when the second moving block and the third moving block move oppositely, a heat insulation plate can be driven to move through first pin shaft seats, connecting rods, moving frames and second pin shaft seats, and the moving frame are always movably mounted on the outer sides of corresponding pin shaft columns, so that the moving frames move towards one side of the heat insulation plate when moving, and in this way, the heat insulation plate can stretch into a furnace body to achieve the sealing effect.

Description

technical field [0001] The invention relates to the technical field of furnace door sealing devices, in particular to an industrial furnace door sealing device with simple operability. Background technique [0002] Industrial furnace is a kind of equipment manufactured and used by comprehensive application of materials science, combustion technology, heat transfer, thermodynamics, fluid mechanics, refractory materials, electrical engineering, material mechanics and other disciplines. The working system can be divided into two categories: one is the intermittent kiln, also known as the periodic kiln, which is characterized by the intermittent production of the kiln, and the temperature of the kiln changes in each heating cycle, such as the chamber kiln , trolley kiln, pit kiln, etc.; the second type is continuous kiln, which is characterized by continuous production of the kiln and the division of temperature zones in the kiln chamber.
