The utility model relates to a tubulation counterflow stove, comprising a housing, a hearth, a water tank, a slag discharging hopper, etc. The utility model is characterized in that a heat storage chamber is formed between the hearth and a stove opening formed by surrounding of the top of the water tank, and a plurality of water storing and heat exchanging vertical tubes are homogeneously distributed along the circumference of the hearth in the heat storage chamber. Both the upper end and the lower end of each vertical tube are communicated with the water tank, and the lower part of the water tank is provided with an annular heat conducting flue surrounding the hearth. The flue is communicated with the heat storage chamber by a plurality of smoke vertical tubes passing through the water tank. After a smoke exhausting tube communicated with the annular heat conducting flue passes through the water tank, the smoke exhausting tube is connected with a chimney. The utility model has the advantages of reasonable stove structure, high thermal efficiency, sufficient waste heat utilization and multi-material use. The utility model is the product having good market competitiveness.

Description

The reverse-flow cooking stove of tubulation

The utility model relates to a kind of cooking stove, relates in particular to the reverse-flow cooking stove of a kind of tubulation.

At present, stove and accessory miscellaneous is of a great variety, performance is different, and its structure is generally shell, burner hearth, smoke evacuation tube, deslagging bucket, and ubiquitous weak point is: heating surface area is less, it is slow to conduct heat, thermal loss is big, and the thermal efficiency is low, and is general all for using single-fuel to design, promptly simple coal or the simple oil firing of burning, its use field and scope are restricted.

The reverse-flow cooking stove of a kind of tubulation that the purpose of this utility model is designed at existing weak point in the above-mentioned prior art just, this cooking range structure is reasonable, and thermal efficiency height can use plurality of raw materials, a kind of product that has much the market competitiveness of can yet be regarded as.

The purpose of this utility model realizes by following measure: the reverse-flow cooking stove of this tubulation includes shell, burner hearth, be centered around the water tank that protects the thorax outside and be installed in water inlet pipe on the water tank, outlet pipe, with the deslagging bucket that is arranged on the body of heater bottom, of the present utility model being characterised in that: between burner hearth and the kitchen range mouth that surrounds by tank top, form a heat accumulation chamber, in the heat accumulation chamber, evenly be furnished with many water storage heat exchange standpipes along the burner hearth circumference, this standpipe upper end is communicated with tank top, the lower end is communicated with the water tank middle part, be provided with annular heat conduction flue around burner hearth in the water tank bottom, this flue communicates with the heat accumulation chamber by the many reverse cigarette standpipes of leading that pass through water tank, and is connected with chimney after smoke exhaust pipe that annular heat conduction flue is communicated with passes water tank.

In the utility model, be provided with a high-order steam apotheca that communicates with water tank that exceeds body of heater in body of heater one side; One water level meter is installed on water tank, is used for level monitoring height at any time; On the heat accumulation chamber of upper of furnace body, offer the secondary air mouth.

Cooking stove of the present utility model also is provided with a portable steam copper at kitchen range mouth place, steam copper top is communicated with high-order steam apotheca top by steam hose, its underpart is communicated with high-order steam apotheca bottom water tank by water supply hose, this steam copper is to use in order to produce steam, also, avoid the waste heat waste as the bell of this cooking stove.

The advantage that the reverse-flow cooking stove of this tubulation is compared with prior art possessed is: owing to the heat accumulation chamber is arranged in upper furnace, and be furnished with many water storage heat exchange standpipes, and heat exchange is accelerated, thermal efficiency height, and lead the reverse cigarette of leading of smoke pipe, whole smoke exhaust pipe buries in water tank, has farthest increased heating surface, heat can fully be absorbed by medium, efficient energy-saving, this cooking stove can use pluralities of fuel, and the scope of application is wide, both be suitable for family and used, also be suitable for small-sized organ, factory and enterprise use.

The drawing of accompanying drawing is described as follows:

Fig. 1 is an outline drawing of the present utility model.

Fig. 2 is the A-A cutaway view of Fig. 1.

Fig. 3 is the B-B cutaway view of Fig. 1.

The utility model describes in further detail below in conjunction with accompanying drawing:

As shown in the figure: the reverse-flow cooking stove of this tubulation includes shell (1), burner hearth (2), be centered around the water tank (3) of burner hearth outside and be installed in water inlet pipe (4) on the water tank, outlet pipe (5), with the deslagging bucket (6) that is arranged on the body of heater bottom, between burner hearth (2) and the kitchen range mouth (7) that surrounds by tank top, form a heat accumulation chamber (8), in the heat accumulation chamber, evenly be furnished with many water storage heat exchange standpipes (9) along the burner hearth circumference, this standpipe upper end is communicated with tank top, the lower end is communicated with the water tank middle part, be provided with around the annular of burner hearth in the water tank bottom and lead cigarette channel (10), this flue communicates with heat accumulation chamber (8) by the reverse cigarette standpipe (11) of leading of the six roots of sensation of passing through water tank, leads with annular to be connected with outside chimney after smoke exhaust pipe (12) that cigarette channel is communicated with passes water tank; Be provided with one in body of heater one side and exceed the high-order steam apotheca (13) that communicates with water tank (3) of body of heater, and on this steam apotheca, be provided with steam (vapor) outlet (19) and safety valve (20); One water level meter (14) is installed on water tank, is used for level monitoring height at any time; On the heat accumulation chamber of upper of furnace body, offer secondary air mouth (15), to guarantee the abundant burning of fuel; This cooking stove also is provided with a portable steam copper (16) at kitchen range mouth place, steam copper top is communicated with high-order steam apotheca (13) top by steam hose (17), its underpart is communicated with high-order steam apotheca bottom water tank by water supply hose (18), this steam copper is to use in order to produce steam, also, avoid the waste heat waste, after it is removed as the bell of this cooking stove, can cook herein, or cooking.

This cooking stove in use, fuel is fuel in burner hearth, can use coal briquette, also can use fuel oil, or fuel gas, heat rises and enters circular heat accumulation chamber, the steam copper at heating-range mouth place, produce steam, steam enters high-order steam apotheca by flexible pipe, and water supply hose then constantly imports water steam copper (utilizing the water-head automatic water supplement).The part of waste heat is passed to medium---water in the water tank by hearth wall, a part is passed in the heat accumulation chamber and evenly is furnished with many water storage heat exchange standpipes along the burner hearth circumference, accelerate the heat exchange of water in the standpipe, flue gas enters it annular heat conduction flue that is positioned at the water tank bottom from top to bottom by the reverse smoke pipe of leading, through smoke exhaust pipe flue gas is discharged again, because whole smokejack all buries in water tank, therefore, the waste heat in the flue gas is fully absorbed.

Because the heat that the utility model produced has obtained multistage absorption, conduct heat fast, purpose of energy saving have been reached.
