The hot air and hot water furnace has the advantages of high heat efficiency and energy saving.

Description

The hot air and hot water stove

The utility model belongs to normal pressure hot air and hot water boiler series products, mainly is applicable to all kinds of greenhouses in the north cold area industrialized agriculture, booth and its feeding room, butchers the heating hot blast and the hot water supply that add break.

Be accompanied by China's industrialized agriculture and its feeding industry, butcher the fast development of processing industry, the greenhouse of north cold area, booth and its feeding room, butcher to add in break heating hot blast and hot water supply equipment are proposed new an urgent demand.At present, original and fall behind " flue " formula heating mode, because of its thermal efficiency extremely low, it is slow to heat up, drawbacks such as energy waste is serious are replaced by the various series of heat wind furnaces of development in recent years, hot-blast stove of producing such as Beijing designed 9RFL-20 type hot-blast stove, Chaoyang District, Beijing City hot-blast stove factory and Beijing Yan Bei stockbreeding machine factory of livestock and poultry machinery of China agricultural machinery institute or the like.My institute has also developed series of heat wind furnace product so far since 1992, specified caloric value until 60,80,1,000,000 kilocalories, has played active promoting function to the industrialized agriculture of north cold area and the development of livestock rearing industry from 20,000 kilocalories, 30,000 kilocalories, 50,000 kilocalories.Present problem is that existing hot-blast stove can only carry out and finish the heat exchange of thermal source and air, provides hot blast in room and greenhouse, and has both needed to supply hot blast in the reality in many rooms, also needs hot-water supply simultaneously.For this reason, many users have disposed hot-blast stove and two kinds of equipment of water heater of simple function simultaneously, have increased equipment purchase expense and occupation area of equipment and space, waste energy, and have improved the production operation cost.

The purpose of this utility model can only provide hot blast at existing hot-blast stove exactly, can not carry out the heat exchange of thermal source and water, hot water can not be provided, the problem and shortage that transaction capabilities is single, design provides a kind of hot air and hot water stove, by above burner hearth, body of heater inner ring internal configurations water jacket and the structure of setting up water tank in the discharge flue outside, reach a stove not only can provide hot blast, but also hot water can be provided simultaneously, improve service efficiency, enlarge the scope of application, reduce the equipment purchasing fund, reduce production costs, the purpose of energy savings.

Basic design of the present utility model is, this stove is except that being made of cold wind import, body of heater outer ring, body of heater inner ring, hot-blast outlet, burner hearth etc., above burner hearth, the inboard that is positioned at the body of heater inner ring installing water jacket and the middle heat exchange circle that is connected with water jacket outlet pipe, water jacket water inlet pipe, passing in the water tank of discharge flue integral sealing, the rear end and the water tank of water jacket outlet pipe are connected, constituted heating hot blast and hot water in the hot air and hot water stove of one.

The utlity model has simple in structure, cheap for manufacturing cost, characteristics such as the scope of application is wide, the thermal efficiency is high, reduce production costs, energy savings.

Fig. 1 is a hot air and hot water stove overall structure schematic diagram;

Fig. 2 is the A-A cutaway view among Fig. 1;

Fig. 3 is the B-B profile among Fig. 1.

Piece number explanation among the figure:

1, cold wind import 2, body of heater outer ring 3, body of heater inner ring 4, middle heat exchange circle

5, hot-blast outlet 6, burner hearth 7, water jacket 8, water tank 9, smoke evacuation

Path 10, water jacket outlet pipe 11, water jacket water inlet pipe

Below in conjunction with accompanying drawing the utility model optimum implementation is described in detail.The hot air and hot water stove comprises that cold wind advances 1, body of heater outer ring 2, body of heater inner ring 3, hot-blast outlet 5, burner hearth 6, above burner hearth 6, the inboard fixed configurations that is positioned at body of heater inner ring 3 cross section and is fan-shaped water jacket 7 that is connected with water jacket outlet pipe 10, water jacket water inlet pipe 11 and middle heat exchange circle 4, and the lower surface of middle heat exchange circle 4 contacts sealing with body of heater inner ring 3 bottom surfaces, leaves the gap between its upper surface and body of heater inner ring 3 upper surfaces.Passing in the water tank 8 of discharge flue 9 integral sealings, water jacket outlet pipe 10 is connected water jacket 7 and water tank 8, so far constitutes heating hot blast and hot water in the hot air and hot water stove of one.

When operation is used, to fill with cold water in water jacket 7 and the water tank 8, open air blast and light flame in the burner hearth 6, air-introduced machine with air from cold wind import 1 suck in the air duct in body of heater outer ring 2 and the body of heater inner ring 3 with burner hearth 6 in the hot flue gases that rise carry out heat exchange, middle heat exchange circle 4 forces air to be done in body of heater inner ring 3 passages once to tear open and backflows movingly, prolongs the path and the time of heat exchange, to obtain more heats, hot blast discharges out of the furnace from hot-blast outlet 5, and supply is used; The water jacket 7 that is positioned at burner hearth 6 tops carries out heat exchange with the hot cigarette that burner hearth 6 rises, hot water in the water jacket 7 enters in the water tank 9 from water jacket outlet pipe 10, fume afterheat in the discharge flue 9 heats the water in the water tank 9 again, heated hot water flows out supply from water tank 9 to be used, and cold water injects in the water jacket 7 from water jacket water inlet pipe 11.
