Abstract

A high-energy straw-fired furnace is used in countryside cooking tools. A short columniform sealing cover, the diameter of which is larger than the diameter of a furnace body, is arranged at the columniform furnace body. An internal furnace inside the furnace body is arranged as a tube with the variable diameter of the large upper opening diameter and the small lower opening diameter or as a straight tube. The top of the internal furnace is provided with a feeding opening, and the lower end of the internal furnace is provided with an ash dredging opening. The outer circle at the upper edge of a furnace mouth is cast with vortex vanes and is drilled with a secondary air inlet hole. The furnace bottom is provided with the secondary air inlet hole. A heat preservation layer and a fire barrier circle are arranged inside an upper sealing cover and are downwards welded at a furnace mouth plate and upwards fastened at the big circle of an upper cover. The furnace mouth is provided with a rotating fire furnace mouth. The lower part at the middle ring of the furnace circle of an upper cover is cast with furnace circle temperature barrier vanes which are downwards arranged orderly. An outer cover casing is provided with a smoke outlet. An upper cover is welded with the furnace body and the internal furnace passes through the furnace mouth plate. The furnace has the characteristics that the firewood can be gotten everywhere; the furnace fires fast and fiercely; the furnace has good delaying character and high efficiency and does not cause pollution; the furnace is in favor of the environmental protection and is worth popularizing.

Description

High energy straw burner

It is the cooking stove of fuel with the straw that the utility model relates to a kind of, especially be the cylindrical seal closure that adds in the above below furnace design being become, its above burner hearth bore big, little or the straight tubular of following bore, furnace port diameter is again less than the burner hearth bore, and has activity swingfire fire door on fire door, and the place is provided with cyclone blade at secondary intake opening, be provided with the warm blade of barrier with furnace top cover, and the high energy straw burner of charge door is arranged.

At present, China rural area generally adopts an old-fashioned pot stove to burn the material phenomenon of cooking, it is very much the expense material, low and the big contaminated environment of cigarette of the thermal efficiency also wastes time and energy, use the combustible scope also wideless, for solving the difficult problem of this band universal phenomenon, people have done many good tries, but all can not reach desirable stage.

The purpose of this utility model will provide a kind of similar common people the straw stove of the normal first class of saying of pot exactly, makes fire door and position, the bottom of a pan more suitable, heat is more concentrated, and the burner hearth firepower is violent, does not have dirty cigarette, economize bavin, wide with combustion bavin scope, the high energy straw burner that heat release rate is higher.

The utility model is finished the technical scheme that its invention task takes: on columniform body of heater, install a short cylindrical shape seal closure bigger additional than furnace diameter, burner hearth in its body of heater, it is big to be arranged to top bore, reducing cylinder that following bore is little or straight tube, in add grate, in burner hearth upper end charge door is arranged, there is gray-drawing port the lower end, pass shaft, can add bavin and draw black dirt, fire door upper edge periphery is cast with the orderly blade of arranged askew, is drilled with a secondary intake opening in the middle of each blade, drop-bottom is provided with the secondary air mouth, the burner shell of last seal closure, heat-insulation layer and barrier pyrosphere are inserted in successively, be welded in downwards on the fire door plate, upwards be fastened on the loam cake great circle, the furnace port diameter of fire door plate is less than the burner hearth bore, and fire door is provided with activity swingfire fire door, loam cake stove circle adapter ring bottom has the orderly stove circle of oblique downward arrangement to hinder warm blade, on the bonnet shell outlet flue is arranged, last seal closure is welded on shaft and the interior thorax by the fire door plate.

Adopt above scheme, be highly advantageous to and add bavin, get angry soon, firepower is violent, thermal efficiency height, one jin of faggot can boiled water more than 7 jin, and flue dust is little, also can continue material, and boiled speed with water gaging is faster than liquefied gas furnace, be coal stove 4-5 doubly.

This accompanying drawing is the specific embodiment of utility model.

The embodiment that now provides in conjunction with the accompanying drawings specifies the utility model.

Wherein: (1) burner hearth, (2) shaft, (3) heat-insulation layer, (4) furnace bottom, (5) fire grate, (6) gray-drawing port, (7) charge door, (8) burner shell, (9) heat-insulation layer, (10) barrier pyrosphere, (11) swingfire fire door, (12) loam cake stove circle, (13) outlet flue, (14) secondary exhaust vent, (15) cyclone blade, (16) secondary air mouth, (17) stove circle hinder warm blade, (18) fire door plate.

Fig. 2 is the vertical view of burner

Fig. 3 is a swingfire fire door vertical view

Fig. 4 is the furnace bottom view

In Fig. 1, shaft (2) is inserted in heat-insulation layer (3) and burner hearth (1) successively, vertical and furnace bottom (4) welds, dog-house pipe (7) and gray-drawing port pipe (6), be fastened on the burner hearth (1) with screw, pass heat-insulation layer (3) and shaft (2), be added with lid outside, heat-insulation layer (3) is fixed on the shaft by iron bar.

Figure (2) is the burner vertical view; Loam cake stove circle (12) is by the big stove circle of loam cake, form with adapter ring that has the warm blade of barrier (17) and inner cap, its burner shell (8), and heat-insulation layer (9) and the barrier pyrosphere (10) be inserted in successively, be welded on the fire door plate (18), fire door plate (18) is welded in again on shaft (2) and burner hearth (1) mouth, and burner shell (8) is fastening with the vertical screw of using in the big outer ring of loam cake stove circle (12) with the heat-insulation layer upper end, the height of cataract or glaucoma pyrosphere (10) is lower than heat-insulation layer (9) slightly, is not connected with the top.Outlet flue (13) passes burner shell (8) and heat-insulation layer (9) welds extremely thereon.This burner diameter can be greater than shaft, also can the same major diameter.

Fig. 3 is a swingfire fire door vertical view.Week is the orderly blade of arranged askew in this fire door, and extremely on interior week, each blade pitgh has 20 millimeters in weldering, and integral body can arbitrarily pick and place.

Fig. 4 is the furnace bottom view, along round edge three air inlets is arranged above, burner hearth can the seat in furnace bottom central authorities, mutually not saturating with these three air ports.

Realizing best way of the present utility model, is that outlet flue will add three cigarette saving tubes, and to increase suction, this stove is just as the first sample of native kitchen range kitchen range pot in rural area, and is convenient and practical.Be not limited to some areas, some countries, so long as the rural area is all very suitable, this stove can with gas furnace than soon, than energy-conservation, than saving money, be the numerous rural subscribers of China for solving the desirable kitcheners of coal-fired crisis, be worth promoting on a large scale.
