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.

[0003] After retrieval, Chinese Patent No. CN 210399995 U discloses a mechanical sealing device for industrial furnace kiln doors, which includes a main connecting rod, an upper lifting connecting rod, a lifting connecting rod adjusting sleeve and a lower lifting connecting rod, the main connecting rod There are two. The upper lifting link and the lower lifting link are connected with the lifting link adjustment sleeve through a screw to form a vertical link assembly. The position shaft is connected with one end of the main connecting rod, and forms a three-link moving structure, and two of the three-link moving structures are arranged symmetrically on the left and right sides of the furnace door; the middle part of the main connecting rod passes through the furnace The door connecting shaft is connected with the furnace door, and there is a roller on the other end of the main connecting rod. The roller is located in the furnace door lifting track, and the sealing and pressing are realized by using the weight of the furnace door itself and the movement of the three links, without the need for additional equipment to provide external force , the three-link movement principle solves the disadvantages of traditional self-weight pressing at the same time, but this device has defects in the sealing process of the furnace door, which cannot guarantee the sealing of the furnace body, and it is easy to cause the phenomenon that the seal is not tight, resulting in the internal leakage of the furnace body. Unstable pressure, insufficient temperature, etc.
