Abstract
The utility model provides a briquette boiler door which is a box-type boiler door. The briquette boiler door comprises a box body (1) and a box cover (2), the upper edges of the box cover (2) are connected with the edges of the box body (1) through hinges (3), an opening ring (4) is arranged at the lower end of the box cover (2) and is connected with a lifting mechanism (5), and the box cover (2) can be opened or closed through operating the lifting mechanism (5). The box-type boiler door is communicated with a boiler furnace, when the boiler is used, the briquette can be placed in the box-type boiler door in advance so as to preheat and distill the briquette, thus the briquette can be rapidly ignited in the burning process.
Description
Technical field
The utility model relates to boiler, and the particularly fire door of boiler specifically belongs to a kind of fire door of molded coal boiler.
Background technology
The fire door of existing molded coal boiler, its sealing and heat insulating ability are poor, more do not make the function of moulded coal preheating, destructive distillation.
The utility model content
The purpose of this utility model provides a kind of sealing and good heat preservation performance, moulded coal is had the molded coal boiler fire door of preheating, destructive distillation function.
A kind of molded coal boiler fire door that the utility model provides is box fire door, comprises casing and case lid, the case lid upper end-face edge is connected with hinge with the casing edge, the case lid lower end is established and is opened ring, and open ring and be connected with elevating mechanism, but operation elevating mechanism closure or openness case lid.Described box fire door can be placed in one moulded coal in advance and play preheating, destructive distillation effect just as a preheating, destructive distillation storehouse, makes that moulded coal ignition when burning is fast.
Baltimore groove is established at described casing edge, and sealing strip is set in the groove, and described case lid edge is provided with press strip, and when case lid closed on the casing, deadweight compressed the interior sealing strip of casing Baltimore groove to the press strip of case lid by case lid, makes the oven door sealing performance improve greatly.Described sealing strip is the lead powder packing.
Heat-insulation layer is established in described casing and case lid inboard, has effectively improved the heat-insulating property of fire door.
Compared with prior art, the utility model adopts box design, not only sealing and good heat preservation performance, and can be used as the space of moulded coal preheating, destructive distillation in the casing, help moulded coal to enter burner hearth burning zone ignition fast.

Among the figure: casing-1, case lid-2, hinge-3 is opened ring-4, hoisting mechanism-5, Baltimore groove-6, sealing strip-7, press strip-8, asbestos heat-insulation layer-9, body of heater-10, wire netting-11, refractory cement heat-insulation layer-12.
The specific embodiment
Below the utility model is described in further detail for the contrast accompanying drawing.
A kind of molded coal boiler fire door shown in Fig. 1-3 is box fire door, comprises casing 1 and case lid 2, case lid 2 upper end-face edges are connected with hinge 3 with casing 1 edge, case lid 2 lower ends are established and are opened ring 4, open ring 4 and are connected with manual lifting mechanism 5, but operate elevating mechanism 5 closure or openness case lids 2.
Baltimore groove 6 is established at casing 1 edge, and lead powder packing 7 is set in the groove, and case lid 2 edges are provided with press strip 8, and when case lid 2 closed on the casing 1, deadweight compressed lead powder packing 7 in the casing Baltimore groove 6 to the press strip of case lid 8 by case lid.
Box fire door is communicated with the burner hearth of body of heater 10, when boiler is enabled moulded coal is placed box fire door in advance, makes it obtain preheating, destructive distillation, and moulded coal can very fast ignition when burning like this.
