Abstract
The invention discloses a sealing furnace door structure, which comprises a furnace body and a furnace door arranged on the end opening part of the furnace body, wherein a lifting mechanism for controlling the furnace door to move up and down is arranged on the end opening part of the furnace body; furnace door guiding rails are arranged on both sides of the end opening part of the furnace body; a furnace door base is also arranged on the furnace body below the furnace door; an inclined end face of which the outside is high and the inside is low is arranged at the upper end of the furnace door base; and a roller matched with the inclined end face is arranged at the bottom of the furnace door. The sealing furnace door structure can solve the problem of poor sealing of the furnace door caused by discrepancy in the position of the furnace door due to the welding position of the roller, has a simple structure and runs stably and reliably.
Description
Technical field
The present invention relates to a kind of furnace door sealing structure.
Background technology
Upper lower open-type sealing door is used for industrial heat treatment furnace in insulation and the sealing of heat treatment process, traditional upper lower open-type sealing door mainly passes through at fire door both sides welding roll, pass through lift mechanism lifts road name during unlatching, rely on the fire door own wt that fire door is descended and furnace sealing when closing, this structure causes fire door to have the slit sealing effectiveness bad between fire door and the body of heater after closing because the welding position of roller is equipped with skew, causes the furnace high-temperature gas leak.
Summary of the invention
Technical problem to be solved by this invention just provides a kind of furnace door sealing structure, can avoid the fire door position because of the bad problem of the roller welding position oven door sealing that there is any discrepancy causes.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: a kind of furnace door sealing structure, comprise body of heater and be located at the fire door of body of heater port part, the body of heater port part is provided with the elevating mechanism that the control fire door moves up and down, body of heater port part both sides are provided with the fire door guide rail, it is characterized in that: also be provided with the fire door base on the body of heater of described fire door below, described fire door base upper end is provided with high outside and low outside inclined end face, and described fire door bottom is provided with the roller with the inclined end face mating reaction.
Preferably, the inclination angle of described inclined end face is preferably 5～30 °.
Improved, described fire door bottom also is provided with elastic buffering mechanism.
Preferably, described elastic buffering mechanism comprises buffer spring, and described buffer spring is connected to the fire door bottom by lead, under the normal closed condition of fire door, movable space is arranged between the bottom face of described buffer spring and inclined end face.The severe impact that prevents the fire door too fast decline of possibility and occur.
The present invention adopts said structure, can avoid the fire door position because of the bad problem of the roller welding position oven door sealing that there is any discrepancy causes.Simple in structure, stable and reliable operation.
Description of drawings
The invention will be further described below in conjunction with accompanying drawing:
Fig. 1 is the structural representation of furnace door sealing structure of the present invention.
The specific embodiment
As shown in Figure 1, be a kind of furnace door sealing structure of the present invention, comprise body of heater 1 and be located at the fire door 2 of body of heater 1 port part, the body of heater port part is provided with the elevating mechanism that the control fire door moves up and down, elevating mechanism of the present invention fire door volume machine 31, upper roller 32, bottom roller 33 and steel wire rope 34 as shown in FIG. consists of, body of heater port part both sides are provided with fire door guide rail 4, and fire door adopts known common structure with cooperating of guide rail, is not described further at this.Also be provided with fire door base 5 on the body of heater of described fire door below, described fire door base upper end is provided with high outside and low outside inclined end face 51, described fire door bottom is provided with the roller 6 with the inclined end face mating reaction, the inclination angle of described inclined end face is preferably 5～30 °, described fire door bottom also is provided with elastic buffering mechanism, elastic buffering mechanism described in the present invention comprises buffer spring 71, described buffer spring is connected to the fire door bottom by lead 72, under the normal closed condition of fire door, movable space 8 is arranged between the bottom face of described buffer spring and inclined end face.
