Technical Field

The invention relates to a stove for cooking, boiling water and warming.

Background

Since the heating stove that has the intermediate layer begins, there is more than 40 years of history at least, the diameter that adopts the heating common knowledge to all increase and decrease furnace according to the size of indoor area divides 60, 80, 100, 120, and the diameter of furnace is big more, and the radiator of area is more, and of course, the coal of burning is also more, just one example: the hearth with the diameter of 100 burns at least 100 kilograms of coal for 8 hours and in different time periods. The heating cost in 8 hours is 100 yuan per kilogram according to the average price per yuan at present, and if the heating cost is not interrupted in 24 hours, the heating cost is 300 yuan. Why there is such a high cost and the choice is made of woolen, one word: cool! For example, a furnace without an interlayer is burnt in a space of 20 square meters indoors, the diameter of the hearth is 60 millimeters, the temperature difference is not different from that of a water heating furnace with an interlayer, the reason is that the structure is unreasonable, for example, a gas is used for boiling water, fire is directly burnt at the bottom of a kettle, a forger master is directly put iron in the fire for burning, and good effects can be achieved. The furnace in the prior art is provided with the fireproof soil, the fire seedlings generated by coal combustion are accessed into the fireproof soil at the first time, the real heat quantity 1 time is not received by water in a hearth adding layer but is blocked by a fireproof soil liner in the hearth, at the moment, the fire seedlings continuously rise, the fire seedlings are pulled into a chimney by the air draft effect of the chimney when the kettle bottom or the pot bottom is directly burnt, although a plurality of pipes with water pipes are arranged at the lower part of an upper chimney of the furnace and are roasted by hot air, the heat efficiency of the hot water in the furnace interlayer is very little, and the furnace only utilizes 1/3 heat energy, namely the fire is not directly burnt, but the hot air effect generated by the fire is utilized for temperature transfer, which is the current situation.

After the technical scheme is adopted, the invention has the beneficial effects that:

in the prior art, a miszone is considered that a direct incineration hearth can be damaged, so that the direct incineration hearth is adhered to the periphery of the hearth by using refractory soil, the hearth with mesons inside can easily burn out, and the cylinder door of a fire combustion engine depends on the protection of medium circulation to prolong the service life as well as all engine principles. Similarly, the body hearth with the medium is directly burnt by fire, so that the problem is solved, how to burn is more reasonable, firstly, the body hearth is used for cooking and cooking by water, the flame is guided to be directly supplied to the bottom of a pot or the bottom of a kettle, and the burning hearth is required to be vertical, so that the multi-channel burner pipe is embodied that the flame is directly pulled up, the pot bottom and the kettle bottom are burned, the burning hearth supplies heat, and both the pot bottom and the kettle bottom are burned; when heating is needed, a rotary joint arranged on the incineration hearth moves a handle through manpower to rotate the incineration hearth by an angle of 45 degrees, a honeycomb briquette fire-penetrating hole effect is generated between the multi-channel incineration pipes, so that flame is enabled to be directly communicated with a chimney, wind borrows fire force, fire borrows wind force, a multi-channel incineration pipe structure arranged in the incineration hearth not only helps to burn but also is incinerated, and the heat exchange effect is exerted to the best state; thirdly, when not needing cooking and heating, burning furnace and moving the handle through the manpower, blockked the chimney exhaust effect when rotatory 90 degrees angles and for the form of banking up a fire, at this moment, though the multichannel burns the pipe and does not play a role, nevertheless burns and has the interval between furnace body appearance and the interior oven, still plays the exhaust effect of miniwatt scope and not fire, has ensured that whatever time quantum can cooking and heating at any time.

The lower end face of the incineration pipe is fixedly connected with an end socket buckle cap at an annular welding point which is firstly contacted with fire, so that the welding point is not contacted with the fire, and the service life of the incineration pipe is better protected in a heat conduction and transmission mode; the flange plates arranged on the connecting wire pipes at the two ends of the incineration hearth are arranged for convenient maintenance.

Burn furnace body axial rotation to perpendicular angle degree, the setting has produced the honeycomb briquette and has penetrated the fire hole effect between burning the this internal multichannel of burning furnace thorax and burn the pipe, under the guide of vertical honeycomb briquette and penetrated the fire hole ventilation effect, the direct pot or the kettle bottom of burning a fire turns back again and gets into the flue, when burning furnace body rotation 45 degrees angles, multichannel burns pipe upper portion and directly goes up the flue to the flue mouth, burn the vertical ventilation effect of pipe at the multichannel, the chimney accelerates under the convection current guide, this internal multichannel that has the medium of burning a fire directly burns and goes into the flue on burning the pipe side, burn furnace body and for the shape of banking up a fire when the ninety degrees angles of rotation.

The invention has the advantages that the outermost sides of the fastening covers at the two ends of the multichannel incineration pipe are in annular flanging shapes, and the fastening cover end faces at the two ends are in a plane shape, but not in a circular arc end socket shape; as tap water is heated to generate steam inevitably, in case of poor pipeline circulation and very large gas expansion pressure, the end face of the buckle cover provides creep space for thermal expansion and cold contraction deformation, for example, the same gap is reserved between a railway track and a track joint and between a bridge and a bridge joint.

The fuel in the combustion area is not limited to any fuel, biomass particles can be used, other nearly environment-friendly fuels such as anthracite, blue coal and coke and artificial boards can also be used, the heating furnace is an automatic-combustion heating furnace without additional external force, combustion-supporting equipment such as an external fan is not needed, and the use cost of the heating furnace is reduced. In conclusion, the invention has the advantages of high heat exchange utilization rate, simple structure, extremely low failure rate, low cost for replacing the incineration hearth, low use cost, low manufacturing cost and low maintenance cost and wide application range.
