The utility model is characterized in that the middle of an upper part is a boiled water tank, both sides of a lower part is a hot water tank, the middle of the lower part is provided with a movable coal stove which can pull out and push in freely, the coal stove is arranged on a pair of parallel tracks, and the inside of hot tanks on both sides of the coal stove is symmetrically provided with two centrifugal dust separators. The utility model has the characteristics of high thermal using efficiency, low discharging dust concentration, easy operation, etc.

Description

Tea furnace

The utility model relates to the tea furnace that a kind of fire coal is heated up water.

Utilize coal-fired tea furnace of heating up water large in the variety at present, but it mainly contain two kinds of forms.First kind of form is that tea furnace adopts steel plate to be welded into a cylindric overall structure, the bottom of tea furnace is the combustion chamber, top is water tank, by the direct heating water tank of burning coal liberated heat bottom, make water boiled, the fire door that adds fuel adopts the form of hinge, opens during coal, closes after adding.Second kind of form is that tea furnace adopts steel plate to be welded into the ring-shaped cylinder shape, and the tea furnace center is the combustion chamber, is water tank around the combustion chamber, takes away bell during coal, adds the back bell is sealed up.In order to guarantee the heat insulating ability of boiled water tank, packed one deck insulation material at tank outer wall, the flue dust of these two kinds of tea furnaces all is that the flue by sidewall directly comes in the atmosphere.Because above-mentioned two kinds of tea furnaces add the fire door of fuel or the red-hot district that bell all is in stove, this exposed fully fire door or bell a large amount of heat energy that all can scatter and disappear; Water tank all is directly to contact with fuel chambers on the other hand, along with burner hearth is constantly carrying out the heat transmission with water tank, has reduced coal-fired temperature, and coal can not fully be burnt, and causes heat energy efficiency lower.In addition, flue dust all is directly not come in the atmosphere through handling, and also can produce certain influence to environmental pollution on every side.

The purpose of this utility model provides a kind of heat energy efficiency height, the low tea furnace of discharging dust concentration.

To achieve these goals, be boiled water tank in the middle of the tea furnace top, the both sides, bottom are boilers, in the middle of the bottom the movable coal fire stove that can freely pull out, push are set, the coal fire stove is placed on the pair of parallel track.

As to further improvement of the utility model, in the boiler of coal fire stove both sides, be symmetrical arranged two centrifugal dedusters.After the flue dust of burning purifies through centrifugal deduster like this, be discharged in the atmosphere, reduced surrounding environment is polluted by chimney; On the other hand, the heat energy in the flue dust is done further heat exchange through centrifugal deduster and boiler water, has utilized flue dust heat energy.

The utility model, can be pulled out the coal fire stove when adding fuel easily owing to selected for use the coal fire stove that is separated from each other with whole stove to make thermal source, pushes after adding to get final product.Around the coal fire stove heat-insulation layer is arranged again, guaranteed fire box temperature, coal is fully burning at high temperature, and adding the fuel fire door is the combustion chamber of a sealing, has heat energy utilization rate height, discharges characteristics such as dust concentration is low, and can also be used to cook when the coal fire stove is pulled out.

Below in conjunction with accompanying drawing the utility model is elaborated.

Fig. 1 is an external structure schematic diagram of the present utility model.

Fig. 2 is an internal structure schematic diagram of the present utility model.

Fig. 3 is the external structure schematic diagram of coal fire stove.

Fig. 4 is the internal cross section structural representation of coal fire stove.

Fig. 5 is the structural representation of centrifugal deduster.

As seen from Figure 1, Figure 2, the utility model is made up of boiler 2, coal fire stove 3, heat water valve 4, hot water valve 5, chimney 7, intake chamber 10, steam convection tube 11, cold water storage cistern 17, boiled water tank 18, heat-insulation layer 19 etc., its profile is bookcase shape, outer wall adds heat-insulation layer 19, aluminium alloy or galvanized iron sheet packing are adopted in the surface, wide at the top and narrow at the bottom, a platform is established at the middle part, is convenient to water receiving and places thermos flask.Its positive suitable position is provided with a heat water valve 4 and a hot water valve 5 respectively, and boiling water is drunk for people, and hot water is washed for people and washed one's hair or other use.For the incrustation scale in regular venting boiled water tank 18 and the boiler 2, hot water blowoff valve 8 and boiling water blowoff valve 9 have been installed respectively in its side.In the middle of the top of tea furnace is boiled water tank 18, and the both sides, bottom are boilers 2, and being provided with one in the middle of the bottom can freely pull out, the movable coal fire stove 3 that pushes, and coal fire stove 3 is placed on the pair of parallel track 1, during coal coal fire stove 3 is pulled out to get final product.Parallel orbit 1 is symmetrically welded the lower end of boiler 2 inboards and with ground certain distance is arranged.Be symmetrical arranged two centrifugal dedusters 16 in the boiler 2 of coal fire stove 3 both sides, the flue dust of burning is discharged by chimney 7 after centrifugal deduster 16 purifies.In order to improve thermal energy exchange efficient, combustion chamber 12 is enclosed in the body of heater, and is welded with equally distributed heat exchanger fin 13 on the 12 contacted boiled water tanks of combustion chamber, and 12 top is equipped with fire board 14 in the combustion chamber, is used to improve the fire door temperature.Cold water storage cistern 17, boiler 2, boiled water tank 18 are communicated with by water pipe 15 and hole, garden respectively, and three water tanks form three grades of reverse circulation heat and transmit, and utilize insulation material to isolate each other.Front upper at stove is installed a water-thermometer 6, is used to show the temperature of boiling water.Drinking water boiler adds water can directly receive water pipe intake chamber 10, and the employing ball-cock assembly is controlled the water level in the cold water storage cistern 17 automatically.

By Fig. 3, Fig. 4 as can be known, the coal fire stove is made of fire door 20, grey chamber 23, pulley 24, boiler clothing 25, fire door 26, flue 27, burner hearth 28 etc., body of heater is the long bodily form, the bottom is equipped with four pulleys 24, whole stove is supported by pulley 24, be placed on the parallel orbit 1, and can on parallel orbit 1, slide front and back.On the furnace wall, settle a handle 22, pull out body of heater when being convenient to coal.In order to prevent that body of heater is pulled through track,, be welded with retaining 21 at the end of parallel orbit 1.In order to guarantee the abundant burning of coal, except that burner hearth 28 bottoms supply air, also be provided with secondary air duct 29 in flue 27 outsides, make air through secondary wind preheating chamber 30, supply with the enough oxygen of fire door 26.Burner hearth 28 can be built into honeycomb briquette shape bladders, uses coal briquette to do fuel, also can be built into general burner hearth and burn the piece charcoal, and the size of stove fire can be adjusted fire door 20 and control.

As shown in Figure 4, centrifugal deduster is made of flue 31, clear dirt road 32, centrifugal dust-removing tube 33, spiral smoke outlet flue 34, main body is one cylindric, when from the high-temperature smoke of combustion chamber along flue 31, after entering centrifugal dust-removing tube 33, flue dust is made circumference and is flowed in cylinder, by action of centrifugal force, dust in the flue dust is removed, and dust is discharged downwards along clear dirt road 32 then.

The specification size of tea furnace can be by the series of products of how much making of output.
