Description

The hybrid hot-blast stove that vegetable greenhouse is heating

The utility model belongs to the heating hybrid hot-blast stove of greenhouse heating equipment, particularly vegetable greenhouse of planting vegetable.

At present, at China vast rural area vegetable greenhouse heating equipment in winter, most vegetable greenhouse all adopts the stove that has wall with flues, or the stove of lengthening flue, rely on the stove and the heat radiation of wall with flues or the heat radiation of stove and flue to heat, weak point is that heating temperature is low, consume fuel is many, temperature fluctuation is big, and cigarette, dust are seriously polluted to the greenhouse, adopt steam or hot water space heating boiler to heat to the greenhouse by radiator in addition, but cost height, input is many, equipment complexity, the vegetables cost height of production.

The hybrid hot-blast stove that provides a kind of vegetable greenhouse heating is provided the purpose of this utility model, can guarantee that not only the vegetables in the greenhouse grow under suitable temperature and suitable air humidity, consume fuel is few, the greenhouse is not polluted, and it is lower than cost with heating boiler, less investment, equipment rational in infrastructure, the vegetables cost of production is low.

The utility model is achieved in that the hybrid hot-blast stove that a kind of vegetable greenhouse is heating, comprise the combustion chamber, heating clamber, air blast, hot-blast outlet and flue, vertical heating clamber and horizontal heating clamber are connected as a single entity, at vertical heating clamber middle part the heat dissipation chamber that has heat abstractor is being set, the bottom of heat dissipation chamber is communicated with the combustion chamber that has the water jacket furnace wall, the fire grate that has air-blast device is installed in the bottom of combustion chamber, the uniform heating tube of level that is being communicated with horizontal heating clamber on the rear wall of heat dissipation chamber, the end face of heat dissipation chamber and other side-closed, the other end of horizontal heating clamber heating tube is communicated with flue box by shrouding, the water tank that has gland steam exhauster is being set on the top of horizontal heating clamber, water tank is communicated with the water jacket furnace wall of combustion chamber by pipeline, is provided with exhaust duct at the top of vertical heating clamber, and gland steam exhauster feeds in the exhaust duct, upper back at horizontal heating clamber is provided with air blast, and the exhaust outlet of air blast is communicated with horizontal heating clamber by the air channel.

When the utility model uses, the fuel combustion of combustion chamber, heating heat dissipation chamber, flame is by the uniform heating tube of horizontal heating clamber level, after the heating tube heating, flue gas is drained from flue box, air blast is blown into the rear portion of cold wind from horizontal heating clamber, the heat that distributes through heating tube heats, again the heat that distributes through heat dissipation chamber further the hot blast of heating enter exhaust duct and mix with the water vapour of gland steam exhauster discharge, send into the greenhouse by airduct, the water vapour in the gland steam exhauster is that the water in the water jacket furnace wall of combustion chamber is heated by pipeline and enters water tank, sends into exhaust duct through gland steam exhauster again.The heat secondary heating that cold wind of the present utility model distributes through heating tube and heat dissipation chamber, thermal efficiency height, consume fuel is few, can guarantee required temperature in greenhouse and the airborne humidity of heating, promote the growth of vegetables, the greenhouse is not polluted, this equipment rational in infrastructure, cost is low, and the vegetables cost of production is low, is the heating hot-blast stove of a kind of vegetable greenhouse that is easy to promote.

Fig. 1 is a structural representation of the present utility model, Fig. 2 is an A-A cutaway view of the present utility model, below in conjunction with accompanying drawing utility model is further described, the hybrid hot-blast stove that a kind of vegetable greenhouse is heating, comprise the combustion chamber, heating clamber, air blast, hot-blast outlet and flue, vertical heating clamber (9) and horizontal heating clamber (2) are connected as a single entity, at vertical heating clamber (9) middle part the heat dissipation chamber (10) that has heat abstractor is being set, heat abstractor can be distributed on heat dissipation chamber (10) periphery wall and last end face on the tongue (11) of sealing, corresponding through hole is communicated with the tongue (11) of sealing on heat dissipation chamber (10) perisporium and on the last end face, heat abstractor also can be distributed on heat dissipation chamber (10) periphery wall and last end face on fin, the bottom of heat dissipation chamber (10) is communicated with the combustion chamber that has water jacket furnace wall (12) (13), the bottom of (13) is installed with the fire grate (14) that has air-blast device in the combustion chamber, air-blast device is the blast chamber (16) that has (15) of exhaust hood, exhaust hood has densely covered eyelet on (15), the bottom of blast chamber (16) is provided with air inlet and has the ash discharging hole of valve, when ashes fall into blast chamber (16) from the eyelet of exhaust hood (15), pulling valve can discharge the ashes that fall into, the blast pipe of blast chamber (16) can be communicated with vertical heating clamber (9), utilize the hot blast air blast in combustion chamber (13) in the vertical heating clamber (9) combustion-supporting, the uniform heating tube (4) of level that is being communicated with horizontal heating clamber (2) on the rear wall of heat dissipation chamber (10), the end face of heat dissipation chamber (10) and other side-closed, the other end of the heating tube (4) of horizontal heating clamber (2) is communicated with flue box (6) by shrouding (17), the access hole that has side door (7) is being set on the rear wall of flue box (6), the water tank (3) that has gland steam exhauster (1) is being set on the top of horizontal heating clamber (2), water tank (3) is communicated with the water jacket furnace wall (12) of combustion chamber (13) by pipeline (18), be provided with exhaust duct (8) at the top of vertical heating clamber (9), gland steam exhauster (1) feeds in the exhaust duct (8), be provided with air blast (5) in the upper back of horizontal heating clamber (2), the exhaust outlet of air blast (5) is communicated with horizontal heating clamber (2) by the air channel.
