Abstract

The utility model discloses a water heating stove for school classrooms. A sandwiched water containing heater (3) is communicated with an inner cavity of a sandwiched water containing stove body (1), smoke and flame pipelines (4) are respectively arranged on the upper side and the lower side of the sandwiched water containing heater and communicated with each other via a rotary flue at the inner end of the inner cavity of the sandwiched water containing stove body, and a heating device arranged below the sandwiched water containing heater (3) is communicated with the sandwiched water containing stove body. The sandwiched water containing heater and the heating device are communicated through the inner cavity of the sandwiched water containing stove body, the smoke and flame pipelines are communicated with the upper side and the lower side of the sandwiched water containing heater, accordingly the heating area of sandwich circulatory water of the stove body is enlarged, secondary rotary circulation of smoke and flame heat generated by sufficient combustion of fuels in the inner cavity of the stove body firstly through the heating device and then the smoke and flame pipelines is realized, the heating efficiency of the sandwich circulatory water of the stove body is effectively increased, and accordingly fuel consumption and pollution to outdoor environment air are evidently reduced.

Description

The hot-water heating stove that classroom uses

(1) technical field: the utility model relates to Heating stove; Be specifically related to the hot-water heating stove that a kind of classroom uses.

(2) background technology: do not adopt the school of collective's heating in the prior art, normally adopt the hot-water heating stove of hot water circuit heating; Its structure is to be connected to communicate by circular interlayer appearance water body of heater and interlayer appearance water smoke exhaust pipe to constitute.Exist not enough: the one, it is less that described interlayer holds the body of heater and the smoke exhaust pipe inner chamber endotherm area of water, and some directly acts on fire door place above the body of heater pyrotechnics heat of body of heater inner chamber fuel combustion, and is lower to the recirculated water efficiency of heating surface in its intracavity sidewall interlayer; The 2nd, in addition the pyrotechnics heat that is not fully burned of some fuel holds the water smoke exhaust pipe by interlayer and directly enters chimney and discharge outdoorly, has increased the consumption of fuel; The described dense smoke that does not have clean-burning pyrotechnics to form has seriously polluted outdoor surrounding air again.

(3) summary of the invention: at the deficiency that above-mentioned prior art exists, the hot-water heating stove that provides a kind of classroom to use is provided the purpose of this utility model; Be intended to improve to the efficiency of heating surface of its interlayer recirculated water and reduce fuel consumption and reduce pollution the outdoor environment air.

For achieving the above object, the technical solution of the utility model is achieved in that the hot-water heating stove that this classroom uses, and comprises that mainly interlayer holds the water body of heater; It is to be communicated with interlayer at the inner chamber that described interlayer holds the water body of heater to hold the water calandria; The upper and lower that holds the water calandria at described interlayer is equipped with the pyrotechnics pipeline holds the water body of heater through described interlayer inner chamber inner end revolution flue connection; Below described interlayer appearance water calandria, be provided with heater and be communicated with described interlayer appearance water body of heater.

The utility model is taked said structure, holds water calandria and heater by be communicated with interlayer in interlayer holds the water body of heater, and the upper and lower that holds the water calandria at described interlayer is communicated with the pyrotechnics pipeline, has increased the heating surface (area) (HS to furnace sandwich recirculated water; Realized the pyrotechnics heat that fuel is fully burned and forms at the body of heater inner chamber, passed through heater earlier, improved the efficiency of heating surface effectively furnace sandwich recirculated water again through the secondary rotary circulation of pyrotechnics pipeline; Reduced the consumption of fuel significantly and reduced pollution the outdoor environment air.

(4) description of drawings: Fig. 1 has the front view of part section for the utility model;

Fig. 2 be among Fig. 1 C-C to partial sectional view.

(5) specific embodiment: Fig. 1-shown in Figure 2.The hot-water heating stove that this classroom uses comprises that mainly interlayer holds water body of heater 1; It is to be communicated with interlayer at the inner chamber that described interlayer holds water body of heater 1 to hold water calandria 3; The upper and lower that holds the water calandria at described interlayer is equipped with pyrotechnics pipeline 4 holds the water body of heater through described interlayer inner chamber inner end revolution flue connection (shown in Figure 1); Below described interlayer appearance water calandria 3, be provided with heater and be communicated with described interlayer appearance water body of heater.Described heater normally is 6 by the every row of two rows and is the heating tube 5 that spacing forms and is communicated with (Fig. 1, shown in Figure 2) with described interlayer appearance water body of heater 1.For making things convenient for the teachers and students of school to heat up water, cook, corresponding in the stove fire hole 6 that described interlayer holds above being provided with fire-assembling hole 7 on the water calandria 3 and described interlayer holding the water body of heater.When the teachers and students of school warmed oneself, the pyrotechnics of body of heater inner chamber acted directly on the heating tube 5 earlier and holds water smoke exhaust pipe 11 by the last via interlayer of the secondary rotary circulation of pyrotechnics pipeline 4 and discharge outdoor (shown in Figure 1).Improved the efficiency of heating surface effectively to furnace sandwich recirculated water 10; The fuel of body of heater inner chamber is fully burned, and has reduced the consumption of fuel and has reduced pollution to the outdoor environment air.Cover plate on the fire-assembling hole 78 is taken off, and the part pyrotechnics of body of heater intracavity bottom burning acts directly on 6 places, stove fire hole by fire-assembling hole 7, the teachers and students of school this moment desirable warm heat up water, cook dual-purpose (shown in Figure 1).

Claims (2)

1. the hot-water heating stove that classroom uses comprises that mainly interlayer holds the water body of heater; It is characterized in that: the inner chamber that holds water body of heater (1) at described interlayer is communicated with interlayer appearance water calandria (3); The upper and lower that holds the water calandria at described interlayer is equipped with pyrotechnics pipeline (4) holds the water body of heater through described interlayer inner chamber inner end revolution flue connection; In the below that described interlayer holds water calandria (3), be provided with heater and be communicated with described interlayer appearance water body of heater.

2. the hot-water heating stove of using according to the described classroom of claim 1 is characterized in that: described heater is communicated with described interlayer appearance water body of heater (1) by being two row's heating tubes (5) that spacing forms.
