Description

A kind of biomass solid fuel stove

Technical field

The utility model relates to a kind of biomass solid fuel stove, and this stove and accessory both had been applicable to biomass solid fuel, also is applicable to common solid fuel.

Background technology

Therefore existing Domestic stove all exists such defective owing to be not configured into wind apparatus: the one, and fuel combustion is insufficient, and firepower is little; The 2nd, from opening fire when flare rises, the required time is longer.For overcoming above-mentioned defective, the applicant has invented " a kind of novel stove and accessory ", and (number of patent application is: 200620035632.2), this stove and accessory has disposed blower fan and smoke exhaust pipe, therefore solid fuel is fully burnt and time on fire weak point, unique deficiency be this stove and accessory because special igniter is not installed, therefore igniting is not too convenient, and operation is trouble.

Summary of the invention

The purpose of this utility model is to provide a kind of igniting biomass solid fuel stove easily and efficiently.

For achieving the above object, the solution that the utility model adopts is: this stove and accessory comprises shell, smoke exhaust pipe, flame retardant coating, heat-insulation layer, grate, blower fan and dedusting chamber, flame retardant coating is located at the inner chamber of heat-insulation layer, blower fan is installed on the cylindrical shell under the grate by fan interface, dedusting chamber is located at the bottom of body of heater, it also is equipped with igniting stone or metal plate for standing a stove on as a precaution against fire, guide rail and lighting door in addition, guide rail is fixedly connected on the cylindrical shell, the igniting stone or metal plate for standing a stove on as a precaution against fire is slidably located on the guide rail, have a hole that the igniting stone or metal plate for standing a stove on as a precaution against fire is entered on the cylindrical shell, lighting door is installed in the place, aperture on the cylindrical shell.

One end of above-mentioned lighting door is hinged on the cylinder inboard wall at place, aperture, and the other end is connected with the igniting stone or metal plate for standing a stove on as a precaution against fire by spring, also is fixed with the gag lever post that a restriction point vent is excessively opened on lighting door.

Above-mentioned smoke exhaust pipe formula in the shape of a spiral is distributed in the heat-insulation layer, and the one end is positioned at the top or the burner hearth of combustion chamber, and the other end stretches out body of heater.

The porch of above-mentioned smoke exhaust pipe also is equipped with screen pack.

The igniting stone or metal plate for standing a stove on as a precaution against fire that the utility model adopted is the ready-made stone or metal plate for standing a stove on as a precaution against fire that can buy on the market, and igniter fuel can be liquefied gas, solid alcohol, fuel oil etc.During use, with the advancing slip lighting door that backs down of ignition furnace rim guide rail, the igniting stone or metal plate for standing a stove on as a precaution against fire is put in from the hole to be positioned under the grate, open the igniting stone or metal plate for standing a stove on as a precaution against fire then, make igniter fuel burning, treat that solid fuel on the grate is lighted after, turn off the igniting stone or metal plate for standing a stove on as a precaution against fire, and pull out the ignition furnace dish backward along guide rail, at this moment lighting door is closed under the effect of spring automatically, seals the aperture.Connect fan power at last, make solid force fully burning under the air distribution at blower fan, the slag after the burning enters dedusting chamber by grate, opens the door of dedusting chamber, just can remove the gred smoothly, and waste gas is discharged by smoke exhaust pipe.

The utility model compared with prior art has following effect: (1) therefore lights a fire convenient, fast and safety because igniter has been installed; (2) because smoke exhaust pipe has adopted sped structure, therefore can increase the walking path of hot blast in stove, thereby can improve furnace temperature, reduce thermal loss; (3) owing to the employing blower fan is forced air distribution, so strong wind power, can make stove and accessory open back a few minutes kind and just see flare, and firepower is prosperous; (4) the scroll casing type structure that is adopted tangentially enters in the stove wind, so wind loss is little, energy consumption is low; (5) fuel employing edible fungus culturing discarded object living beings waste materials such as (bacterium slags) is a raw material, and not only cost is low, but but also contaminated solution problem.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is described in further detail.

As shown in Figure 1 and Figure 2, the utility model is made up of shell 1, screen pack 2, smoke exhaust pipe 3, flame retardant coating 4, heat-insulation layer 5, grate 6, igniting stone or metal plate for standing a stove on as a precaution against fire 7, guide rail 8, lighting door 9, blower fan 10, dedusting chamber 11, spring 12 and gag lever post 13, flame retardant coating 4 is located at the inner chamber of the heat-insulation layer 5 on the grate 6, solid fuel is placed on burning on the grate 6, the ash that is burnt is removed through dedusting chamber 11, and institute's exhaust gas discharged is discharged through smoke exhaust pipe 3.In the present embodiment smoke exhaust pipe 3 in the shape of a spiral formula be distributed in 5 li of the outer heat-insulation layers of combustion chamber, the one end is positioned at burner hearth, the other end stretches out body of heater, waste gas enters from an end that is positioned at burner hearth, after screw type pipeline spirals, discharge from the other end, enter smoke exhaust pipe 3 with waste gas, be equipped with metal filter screen 2 in the porch of smoke exhaust pipe 3 for preventing dust.Adopt the smoke exhaust pipe 3 of this sped structure can increase the walking path of hot blast in stove, thereby improve furnace temperature, reduce thermal loss.Blower fan 10 is installed on the metal cylinder 15 by taper fan interface 14 among Fig. 1, Fig. 2, the outer end of taper fan interface 14 is connected with axial flow blower 10 by flange, its the inner tangentially is connected on the metal cylinder 15 by welding, adopt taper fan interface 14 can add the flow velocity of strong wind, and wind is tangentially entered in the stove, thereby can reduce the loss of wind.
