Embodiment Construction

[0012] Specific examples figure 1 and figure 2 As shown, the furnace door 1 stands on the front part of the trolley 2, and the furnace door 1 and the trolley 2 are supported by two sets of sliding support wheels 3. The front end of the trolley 2 is welded with a fixed support frame 4, and the furnace door 1 The outer steel plate and the fixed support frame are connected by a flexible seal regulator assembly 5. The flexible seal regulator assembly has multiple functions such as guiding, buffering, pressing, and adjustment. Further, the flexible seal regulator is collectively referred to as It is composed of inner and outer guiding tubular sleeves, springs and adjusting bolt parts. The outer guide sleeve is installed on the outside of the inner guide sleeve, slidingly fitted, and mainly plays a guiding role in the direction of motion of the furnace door. The inner guide sleeve is equipped with a spring, and the spring extends into the outer guide sleeve, and the spring mainly...

Abstract

The invention discloses a flexible automatic sealing furnace door which is positioned in front of a trolley, wherein the furnace door and the trolley are supported by two groups of sliding supporting wheels; a fixed supporting frame is arranged at the front end of the trolley in a welding manner; an outer side steel plate of the furnace door is connected with the fixed supporting frame by a flexible sealing adjusting device assembly; a front end enclosing plate of the trolley is provided with a heat resistant steel sealing cutter and another heat resistant steel sealing cutter in the welding manner; furnace door cellucotton is arranged at the combined part of the furnace door and the front end of the trolley. The invention aims at solving the technical problems that a trolley type industrial furnace door is large in occupation space, large in energy consumption, large in maintenance difficulty, low in safety factor, easy to deform, and the like, and heat-preservation furnace door cellucotton is short in service life in the prior art, the flexible automatic sealing furnace door disclosed by the invention has the advantages that the special electric control is avoided, the occupation space is small, energy is saved, the maintenance of devices is easy, the safety factor is relatively high, the up-down friction to the heat-preservation furnace door cellucotton is avoided, and the heat preservation effect is good.

Description

Technical field: [0001] The invention relates to a flexible automatic sealing furnace door, which is especially suitable for use on the furnace door of a trolley-type heat treatment furnace. Background technique: [0002] The trolley-type heat treatment furnace door sealing mechanism in the prior art generally uses the opening and sealing method of the combination of the upper and lower slides and the lifting equipment, and relies on the electric lifting equipment to wind and loosen the steel wire rope to achieve the purpose of lifting the furnace door, and Relying on the natural slope of the slideway and the self-weight of the furnace door, the furnace door pulley is driven to press against the furnace mouth to meet the sealing requirements. In actual operation, because the steel wire rope is close to the high temperature area of ​​the furnace mouth, the normal service life of the steel wire rope is seriously challenged, and it often needs to be replaced, and the cost is hi...
