Abstract

The utility model discloses a dual-sealing smoke box of a horizontal internal combustion gas burning boiler. A smoke box door is arranged on a smoke box body through a hinge, and is fixed on the smoke box body by a screw cap through a screw rod arranged on the smoke box body, the inner side of the smoke box door is designed into a secondary lug boss, a smoke box door sealing pad is arranged on the surface of a primary lug boss, the opening side wall of a high-temperature smoke gas region of the smoke box body is designed into a concave table, a smoke box body sealing pad is arranged on the surface of the concave table, the side wall of the lug boss is projected out of the surface of the smoke box body for forming a flange, the surface of the primary lug boss of the smoke box door is pressed on the smoke box sealing pad when the smoke box door is closed, and the side wall of the concave table is projected out of the flange of the smoke box body to be pressed on the smoke box door sealing pad. The utility model has the advantages that the smoke box door of the horizontal internal combustion gas burning boiler adopts a dual-sealing structure, the first layer sealing structure can block the influence on the second layer sealing material by high-temperature smoke gas, and the smoke gas heat is prevented from being outwards conducted. The dual-sealing smoke box door has good heat insulation performance and sealing performance.

Description

Horizontal internal combustion gas fired-boiler double containment smoke box

Technical field

The utility model relates to a kind of smoke box of horizontal internal combustion gas fired-boiler.

Background technology

The horizontal internal combustion gas fired-boiler is to move under barotropic state, and therefore boiler front smoke box flue-gas temperature requires the boiler uptake door to have excellent heat insulation property and sealing property about 750 ℃.At present, horizontal internal combustion gas fired-boiler smoke box door adopts a cover hermetically-sealed construction, and the heat thermal-conduction resistance is little, and the heat conduction is fast, high temperature can be accelerated aging, the inefficacy of encapsulant, the therefore horizontal gas fired-boiler smoke box door heat-proof quality and the equal poor effect of sealing property of this structure simultaneously.

The utility model content

The purpose of this utility model is to provide a kind of heat-proof quality and all good smoke box of sealing property effect for the horizontal internal combustion gas fired-boiler.

The purpose of this utility model realizes in the following way: a kind of horizontal internal combustion gas fired-boiler double containment smoke box, smoke box door is contained on the smoke box body by hinge, and the screw rod that passes through on the smoke box body uses fixed by nut on the smoke box body, the smoke box door inboard is designed to the secondary boss, and the smoke box door sealing gasket is arranged on the one-level boss face; The opening sidewalls in the high-temperature flue gas district of smoke box body is designed to concave station, smoke box body sealing gasket is arranged on the concave station face, the sidewall of concave station protrudes the smoke box surface and constitutes flange, when closing smoke box door, the one-level boss face of smoke box door is pressed on the smoke box body sealing gasket, and the flange that the sidewall of concave station protrudes the smoke box body is pressed on the smoke box door sealing gasket.

The utlity model has following beneficial effect, the smoke box door of horizontal internal combustion gas fired-boiler cigarette and smoke box body adopt double sealing structure, the ground floor hermetically-sealed construction can be blocked the influence of high-temperature flue gas to second layer encapsulant, the blocking-up flue gas heat is outwards conducted, and this double containment smoke box door has excellent heat insulation property and sealing property.
