Abstract

The utility model relates to a heating furnace, particularly a greenhouse used fire coal vaporization hot-blast furnace. The furnace comprises a front furnace body and a back furnace body which communicate with each other via air ducts at the lower part thereof. An upper partition and a lower partition are respectively arranged in a position higher than the air duct inside the back furnace body and at the upper part of the back furnace body, so as to divide the cavity of the back furnace body into three parts, that is, a fume-collecting chamber at the upper part, a heat-dissipation chamber at the middle part and a combustion chamber at the lower part. A plurality of vertical hollow cavity inner pipes penetrating the partitions are arranged between the two partitions. Both the upper end and the lower end of the pipe are opened. An opening is formed on the outer wall at the lower part of the heat-dissipation chamber above the lower partition and communicates with a blast blower. The upper part of the heat-dissipation chamber communicates with a heat transfer pipe and a three-way pipe in sequence. Two heat-dissipating pipes which extend in an opposite direction to the two ends of the greenhouse are arranged on the three-way pipe, and the pipe ends are opened. The upper part of the fume-collecting chamber communicates with a fume exhaust pipe. The fume exhaust pipe penetrates the greenhouse. The fire coal vaporization hot-blast furnace realizes the centralized heat supply of the greenhouse, keeps the temperature inside the greenhouse constant and prevents the crop plants from being frozen. The coal-fired vaporization hot-blast furnace has the advantages of low coal consumption, reduced greenhouse production cost, long heat supply time (up to 12 hours per coal-feeding times) and no need of manual coal feeding.

Description

Warmhouse booth is with coal-fired heat of vaporization wind furnace

1, technical field:

The utility model relates to a kind of heating stove, relates in particular to a kind of warmhouse booth with coal-fired heat of vaporization wind furnace.

2, background technology:

Northern China rural area warmhouse booth, heat supply in winter are taked to put coal stove at interval in the canopy, and the mode of staff on duty coal exists coal consumption big and temperature of shed is unbalanced, easily the problem of frostbite crop.Especially get regularly coal of special messenger night, very trouble.

3, summary of the invention:

It is coal-fired that the purpose of this utility model is to propose a kind of saving, but central heating, and temperature of shed is balanced and keep constant warmhouse booth with coal-fired heat of vaporization wind furnace.

The purpose of this utility model is achieved in that warmhouse booth is provided with forward and backward body of heater with coal-fired heat of vaporization wind furnace, and both are communicated with by the air flue of bottom.The front furnace body roof of the furnace is stamped the bell of quantity-adjustable, and ring oven thorax upper inside wall is provided with vertical rib, is filled with seat clay between rib.Lower furnace portion is provided with fire grate.Have at the bottom of the burner hearth of fire grate top and see burner, have cleaning door at the bottom of the burner hearth of below.Be higher than the air flue place in the rear furnace body and rear furnace body top is respectively equipped with upper and lower dividing plate, the back furnace chamber is divided into the smoke collecting chamber on top, the heat radiation chamber at middle part, combustion chamber three parts of bottom.Be equiped with pipe in the many vertical cavitys that pass dividing plate between two dividing plates, its upper and lower side is all uncovered.Encircle each outer wall of inner tube and be equiped with from bottom to top the integral body shape radiating fin that spirals and arrange in the shape of a spiral.Have flatly on the heat radiation chamber bottom outer wall of lower clapboard top, itself and air blast are communicated with; Heat radiation top, chamber and defeated heat pipe, three-way pipe are communicated with in turn, are equiped with two radiating tubes that oppositely extend to the plastic greenhouse two ends on the three-way pipe, end-blown; Smoke collecting chamber top and smoke exhaust pipe are communicated with, and smoke exhaust pipe passes warmhouse booth.

Warmhouse booth can be realized central heating with coal-fired heat of vaporization wind furnace, and temperature of shed is balanced and can keep constant, has avoided the crop frostbite.Save fire coal, reduce the booth production cost.One time the coal heating time reaches 12 hours, need not the staff on duty coal.

5, the specific embodiment:

The utility model is not subjected to the restriction of following embodiment, can determine concrete embodiment according to the technical solution of the utility model and actual conditions.

Embodiment: shown in Fig. 1-2, warmhouse booth is provided with preceding 12, rear furnace body 6 with coal-fired heat of vaporization wind furnace, and both are communicated with by the air flue 16 of bottom.Bell 9 is stamped at front furnace body 12 burner hearths 10 tops, and ring oven thorax 10 upper inside wall are provided with

vertical rib

11, and 11 on rib is filled with seat clay.Burner hearth 10 bottoms are provided with fire grate 14.10 ends of burner hearth of fire grate 14 tops have sees

burner

13, and 10 ends of burner hearth of below have cleaning door 15.Be higher than air flue 16 places in the rear furnace body 6 and rear furnace body 6 tops are respectively equipped with upper and lower dividing plate 4, the back furnace chamber is divided into the smoke collecting chamber on top, the heat radiation chamber at middle part, combustion chamber three parts of bottom.Be equiped with pipe 7 in the many vertical cavitys that pass dividing plate 4 between two dividing plates 4, its upper and lower side is all uncovered.Encircle pipe 7 outer walls in each and be equiped with from bottom to top the integral body shape radiating fin 8 that spirals and arrange in the shape of a spiral.Have on the heat radiation chamber bottom outer wall of lower clapboard 4 tops flatly, itself and air blast 17 are communicated with; Heat radiation top, chamber and defeated heat pipe 3, three-way pipe 2 are communicated with in turn, are equiped with two radiating tubes 1 that oppositely extend to the warmhouse booth two ends on the three-way pipe 2, end-blown; Smoke collecting chamber top and smoke exhaust pipe 5 are communicated with, and smoke exhaust pipe 5 passes warmhouse booth.

Bell 9 is made up of last 18, screwed lid 21, and last 18, screwed lid 21 is disc, equidistantly has corresponding in twos wind hole 19 on both peripheries, and screwed lid 21 centers are provided with rotating shaft 22, and last spiral cover 18 centers have axis hole 20, and it is placed in the rotating shaft 22.By rotating spiral cover 18, can regulate 18, the relative position in the wind hole 19 on the screwed lid 21, control enters the air quantity size in the burner hearth 10.
