Abstract
The utility model relates to a heating boiler door which comprises a shell; one side of the shell is provided with a bracket; the other side of the shell is provided with a fireproof layer; a press is arranged on the bracket; and a locking device capable of locking the bracket is arranged on the bracket. When the boiler door is opened, a blower needs to be closed firstly, a draught fan continuously works for 2-3 minutes and then stops working, and at the moment, the locking device can release the bracket. As the draught fan continuously works after the blower is closed, CO and CH4 generated in the boiler due to incomplete combustion can be extracted out by the draught fan, therefore, when an operator opens the boiler door, flames and sparks in a hearth can not spray out and explosion can not occur.

The specific embodiment
Embodiment: with shown in the accompanying drawing 2, a kind of heating stove fire door comprises housing 1 like accompanying drawing 1; One side of housing 1 is provided with support 3; The opposite side of housing 1 is provided with flame retardant coating 10, and support 3 is provided with hold down gag, and support 3 is provided with can be with the locking device of support 3 lockings.
Housing 1 is hinged with an end of support 3, and housing 1 is hinged through bearing pin 6 and body of heater with support, and locking device is positioned at the other end of support 3.
Locking device comprises electromagnet 13 and depression bar 4, and a wherein end of electromagnet 13 is fixedly connected with depression bar 4, and the other end of electromagnet 13 is set with sleeve 14, and the other end and the body of heater of sleeve 14 are hinged.
Support 3 is provided with the draw-in groove 15 that holds electromagnet 13, and electromagnet 13 is positioned at draw-in groove 15 with sleeve 14.
The side that housing 1 is provided with flame retardant coating 10 is provided with connecting plate 8, and connecting plate 8 is provided with groove, and flame retardant coating 10 is positioned at groove.
Be fixedly connected with fireguard 9 on the connecting plate 8, connecting plate 8 and fireguard 9 are processed by cast iron materials.
Be provided with sealing gasket 7 around the connecting plate 8, sealing gasket 7 is an asbestos cord, and flame retardant coating 10 is a refractory concrete.
