Abstract
A combustion chamber comprises a shell body, a main heat exchanger and a combustion device. The main heat exchanger and the combustion device are arranged inside the shell body which is provided with a window opening and a cover plate matched with the window opening. The cover plate is connected with the shell body in a detachable mode. Oxides on the shell body or accumulations on the main heat exchanger can be cleaned conveniently, therefore, burning condition can be improved, heat exchanging efficiency can be improved, detaching is convenient, working load is small, and sealing performance of the combustion chamber is not influenced.
Description
Technical field
The utility model relates to a kind of combustion chamber, and it is applicable to the full pre-mix condensing wall-hung boiler.
Background technology
Existing full pre-mix condensing wall-hung boiler is very high to the sealing requirements of combustion chamber, all adopt inseparable chamber, for guaranteeing that flue gas not occurring leaks outside, the general inconvenient dismantle structure that adopts is installed in the combustion chamber, yet in long-term use procedure, burner may produce oxide, meeting relict sediment on the main heat exchanger, if irregularly cleaning will affect combustion conditions and reduce heat transfer effect, but if the dismounting combustion chamber checks cleaning, just need to take distributor chamber and heat exchanger assembly apart, dismounting is inconvenient, and workload is large, and reinstalling after the dismounting understood the seal that affect the combustion chamber.For overcoming these defectives, the combustion chamber of full pre-mix condensing wall-hung boiler is developed.
Summary of the invention
Technical problem to be solved in the utility model is that a kind of combustion chamber will be provided, oxide on the energy easy cleaning burner or the deposit on the main heat exchanger, thereby improve combustion conditions, improve heat exchange efficiency, convenient disassembly, workload are little, do not affect the seal of combustion chamber.
The technical scheme that its technical problem that solves the utility model adopts is: comprise housing, main heat exchanger, burner, main heat exchanger, burner are positioned at housing, the cover plate that housing is provided with window, matches with window, and cover plate and housing removably connect.
The periphery of window, cover plate are provided with corresponding screwed hole on the described housing, and cover plate is threaded with housing.
It also comprises heat insulation foam, heat insulation foam be positioned on the window and with the inwall close contact of window.
It comprises that also sealing is cotton, and the sealing cotton is fixed in the window outside, and there is the cavity corresponding with window size the centre.
Described sealing cotton is provided with the screwed hole corresponding with cover plate, and the cover plate press seal is cotton and be threaded with housing.
Described heat insulation foam, cover plate are provided with corresponding flame-observing hole.
Described window is positioned at the position in the middle of the burner and main heat exchanger on the case panel.
The utility model is compared the beneficial effect that produces with background technology: because the utility model adopts the cover plate that is provided with window, matches with window at burning chamber shell, the scheme that cover plate and housing removably connect, when the oxide on the needs cleaning burner or the deposit on the cleaning main heat exchanger, opening window can be cleared up, thereby improve combustion conditions, improve heat exchange efficiency, convenient disassembly, workload are little, do not affect the seal of combustion chamber.
Description of drawings: Fig. 1 is structural representation of the present utility model.
Fig. 2 is local entities's explosive view among Fig. 1.
The specific embodiment: referring to Fig. 1, shown in Figure 2, the present embodiment comprises housing 8, main heat exchanger 4, burner 5, main heat exchanger 4, burner 5 are positioned at housing 8, the cover plate 7 that housing 8 is provided with window 1, matches with window 1, and cover plate 7 removably connects with housing 8.The periphery of window 1, cover plate 7 are provided with corresponding screwed hole on the housing 8 of the present embodiment, and cover plate 7 is threaded with housing 8.
Further, because the temperature in the combustion chamber is very high, the present embodiment also comprises heat insulation foam 2, heat insulation foam 2 be positioned on the window 1 and with the inwall close contact of window 1, the heat insulation foam of using in the wall-hung boiler can both anti-high temperature more than 1000 ℃, and can prevent fires, therefore can be effectively heat insulation, be convenient to the installation and removal of cover plate 7.
In order to guarantee the sealing of combustion chamber integral body, the sealing cotton 3 that the cavity corresponding with window 1 size arranged in the middle of the present embodiment also comprises, sealing cotton 3 is fixed in window 1 outside and is which is provided with the screwed hole corresponding with cover plate 7, and cover plate 7 press seals are cotton and be threaded with housing.
Further, heat insulation foam 2 and cover plate 7 are provided with flame-observing hole 6, are convenient to check and watch the combustion case of burner.
For the oxide on can easy cleaning burner 5 also can be cleared up deposit on the main heat exchanger, the window 1 of the present embodiment is positioned at the position in the middle of the burner 5 and main heat exchanger 4 on housing 8 panels.
During installation, first heat insulation foam 2 and sealing cotton 3 are fitted on the cover plate 7, then by cover plate 7 heat insulation foam 2 and cotton 3 compressions of sealing are caused on the housing 8, make the inwall close contact of heat insulation foam 2 and window 1, sealing cotton 3 and cover plate 7 are threaded with housing 8 panels by screw.When needing cleaning burner 5 and/or main heat exchanger 4, only need to unload screw, open cover plate, take out heat insulation foam 2 and sealing cotton 3, can clear up convenient disassembly, workload is little, can improve combustion conditions after the cleaning, improve heat exchange efficiency, also can not affect the seal of combustion chamber.
