Assembled hot air stove

Abstract

The invention discloses an assembled hot air stove, and aims to solve the technical problem that: the overall stove is scraped because the conventional hot air stove structure adopts a structural mode that a combustion part and a heat exchanging part are integrally fixed, and once quick-wear parts are damaged, the damaged parts are difficult to replace. The assembled hot air stove comprises the combustion part and the heat exchanging part, wherein the heat exchanging part positioned above the combustion part consists of a primary heating stove body and a secondary heating stove body; groups of primary heating pipes and secondary heating pipes are arranged in the hearth chambers of the two heating stove bodies respectively; the stove body of the combustion part which has a steel board structure is connected with the primary heat exchanging stove body and the secondary heat exchanging body of the heat exchanging part by flanges respectively; air is fed into the two heating stove bodies and the combustion hearth of the heat exchanging part by air blowing boxes and hot air-connecting air passages on the side walls of the stove bodies; the hot air subjected to heat exchange flows into an air-discharging storage box; and a heat source is fed out by a hot air outlet. The assembled hot air stove has the characteristics that the oxidation supply in the hearth is even and abundant, a contact area of the combustion stove and the heat exchanging device is large, the heat source use ratio of the combustion stove is improved, and it is convenient for changing quick-wear parts by using an assembly structure for the stove body.

Description

Technical field: [0001] The invention relates to a hot blast stove, in particular to an assembled hot blast stove. The hot blast stove is suitable for shell-shaped boilers, environmental protection boilers, warm air stoves and drying stoves, and can also be used as rural household stoves, outdoor heating or field heating. Background technique: [0002] At present, the structure of conventional hot blast stoves generally adopts the structural mode of fixing the combustion part and the heat exchange part as a whole. Once the wearing parts are damaged, it is difficult to replace them, often resulting in the scrapping of the entire furnace body. This will cause a lot of waste of resources. And the effect of the combustion chamber of existing hot blast stove generally only is to provide heat source for heat exchange part through furnace hearth, and a part of heat energy is consumed by thick furnace wall, and the heat energy that combustion produces is not fully utilized.

Problems solved by technology

[0002] At present, the structure of conventional hot blast stoves generally adopts the structural mode of fixing the combustion part and the heat exchange part as a whole. Once the wearing parts are damaged, it is difficult to replace them, which often leads to the scrapping of the entire furnace body.

This will cause a lot of waste of resources

Moreover, the function of the combustion chamber of the existing hot blast stove is generally only to provide a heat source for the heat exchange part through the furnace, a part of the heat energy is consumed by the thick furnace wall, and the heat energy generated by the combustion is not fully utilized.
