Description

A kind of greenhouse heating furnace

The utility model relates to the heater that a kind of greenhouse is used, particularly a kind of greenhouse heating furnace.

Warmhouse booth can be built a warm miniclimate in the winter of cold, is beneficial to the growth of plant.But it is not enough or when needing higher temperature in illumination, just need to adopt the way of other auxiliary heating, to reach the plant needed temperature of growing, existing method to the warmhouse booth heating can be divided into electrical heating method and coal heating, all be to heat to warmhouse booth with common electric heater or coal stove, it is big not only to expend the energy, and the effect of heat temperature raising is undesirable.

The purpose of this utility model provides a kind of simple in structure, effective greenhouse heating furnace of heating.

For achieving the above object, the utility model adopts following technical scheme:

The said a kind of greenhouse of the utility model comprises body of heater and grate with heating furnace, have fire door and exhaust opening on the body of heater, body of heater is a double layer jacket structure, the one side has air inlet, opposite side has air outlet, air inlet and air outlet all communicate with the chuck of body of heater, have the heating tube that communicates with its chuck layer in the body of heater.

Heating tube has two kinds, wherein a kind of is the straight tube that is positioned at the body of heater inner and upper, the two ends of straight tube are connected on the inboard wall of furnace body, and communicate with the chuck layer, another kind is the serpentine bend pipe that is positioned at below the straight tube, the two ends of serpentine bend pipe are sagging, and are connected on the inwall with air inlet and the corresponding body of heater of air outlet.

The said a kind of greenhouse of the utility model can be installed on any stove and accessory that uses solid fuel with heating furnace during use, and dry to air inlet with air blast, be heated when the chuck layer of cold wind process body of heater and heating tube, and, reach purpose to the warmhouse booth heat temperature raising from the air outlet discharge.

After adopting technique scheme, a kind of greenhouse described in the utility model is simple in structure with heating furnace, heating is effective, and can use pluralities of fuel as the energy.

Further specify the utility model below in conjunction with drawings and Examples:

Fig. 1 is the longitudinal sectional view of an embodiment of the present utility model;

Fig. 2 is the A-A cutaway view of Fig. 1.

As shown in Figure 1 and Figure 2, the said a kind of greenhouse of the utility model has the body of heater 1 and the grate 8 of round barrel shape with heating furnace, have fire door 7 and exhaust opening 2 on the body of heater 1, lower openings, body of heater 1 is a double layer jacket structure, and the one side has air inlet 3, and opposite side has air outlet 4, air inlet 3 and air outlet 4 all communicate with the chuck of body of heater 1, have the heating tube that communicates with its chuck layer in the body of heater 1.Heating tube has two kinds, wherein a kind of is the two horizontal straight tubes 5 that are positioned at body of heater 1 inner and upper, the two ends of straight tube 5 are connected on body of heater 1 inwall, and communicate with the chuck layer, another kind is the serpentine bend pipe 6 that is positioned at below the straight tube 5, the two ends of serpentine bend pipe 6 are sagging, and are connected on the inwall with air inlet 3 and air outlet 4 corresponding bodies of heater 1.

Straight tube 5 and serpentine bend pipe 6 as heating tube can be provided with one or more according to the volume size of body of heater 1.

During use this greenhouse is installed in the warmhouse booth with heating furnace, on grate 8, put fuel such as coal or timber, lighting the back dries to air inlet 3 with air blast, cold air is heated when the chuck layer of body of heater 1 or heating tube, and be discharged to the warmhouse booth, thereby reach purpose to the air heat of warmhouse booth from air outlet 4.
