Description

Three-ring water jacket fire-depressed type heating stove

The utility model belongs to the cooking stove class, and it is specifically related to a kind of structure of the novel heating stove that has three layers of water jacket.

Along with improving constantly of living standards of the people, civilian heating stove has become the main stove and accessory form of resident's heating, it installs water jacket exactly additional in coal stove, adopt the heat in the coal stove that water is heated, thereafter utilize Natural Circulation to emit heat in the radiator of hot water outside stove and warm oneself, Here it is the alleged simple room heater of people.This civilian heating stove kind is a lot of at present, people wish to have bought the high product of the thermal efficiency in selection, and the designer considers is how to make under the clean-burning prerequisite of coal fully with water jacket draw heat farthest, just increases the heating surface area of water jacket under possible condition.Common in the market heating stove be single water jacket or be at most the structure of double water jacket, this still is inadequate to the heat of drawing in the coal fire.

The purpose of this utility model is for further improving the thermal efficiency of heating stove, under the principle of fire-depressed type coal stove, strengthen the heating surface area of water jacket hand and foot, reasonable and effectively draw heat, a kind of three novel ring fire-depressed type heating stoves now are provided, it has the higher thermal efficiency, economizes coal and multiple use is arranged.

By as above design, the three-ring water jacket fire-depressed type heating stove that this programme provided, it includes shaft, stove benefit, furnace lining, tile, water jacket, fire sealing cover, fire-suppressing cover, the water jacket that it is characterized in that it has three layers, the big water jacket of its outermost layer is positioned in the middle of the furnace lining of shaft and on fire grate, is fixedly connected by water inlet and shaft; Its middle water jacket is positioned at big water jacket and on the top of shaft, is fixedly connected with outer water pipe and big water jacket; Its small water sleeve is arranged in water jacket and contour with it, is fixedly connected with inner conduit and middle water jacket, and small water sleeve communicates with delivery port, and is fixedly connected by outlet pipe and shaft; The inner lower angle sealed attachment of its bank up a fire cage and small water sleeve, the upper surface sealed attachment of the lower end of the cage of banking up a fire and tile; Its middle water jacket the edge extend upward, supporting fire-suppressing cover circle and fire-suppressing cover.

In this programme, its bell is made up of dome and several great circle that cooperates with it at center, all has the rim of the mouth to reach mutual sealing between them.The connection of its fire-suppressing cover circle and the upwardly extending part of middle water jacket and fire-suppressing cover circle all are cooperating between the rim of the mouth with connection between the fire-suppressing cover.Its fire sealing cover is diameter, and it outsidely is the dome on plane less than the internal diameter of small water sleeve.

Adopt this programme can embody following superiority: 1. this three rings fire-depressed type heating stove has three layers of water jacket, increases the heating surface area of water jacket as much as possible, fully draw heat; 2. its middle water jacket and small water sleeve are fully to be exposed among the stove fire, adopt in addition to suppress fiery principle and make the thermal efficiency to improve further, and its heating surface area increases by 50～60% than the product of single water jacket, and its thermal efficiency can reach 90% through preresearch estimates; 3. it covers after fire sealing cover banks up a fire, can keep burning and reach more than 15 hours, open the benefit of banking up a fire during heating, build fire-suppressing cover, the flue gas of coal fire is discharged through twice circuitous smokejack that just can enter, the flue-gas temperature of discharging is less than 40 ℃, and its heat is used fully, in the time of need making meal with it, can remove bank up a fire benefit and fire-suppressing cover, open bell with the pot seat in the hole of furnace roof, pyrotechnics can act directly on the bottom of a pan, can realize the multiple function of a stove; 4. its simple in structure, low cost of manufacture, easy to operate and the thermal efficiency is high, be suitable for making and promoting the use of in batches.

Fig. 1 is the structural representation of this programme three-ring water jacket fire-depressed type heating stove.
