Background technology
Need drying behind the grain harvest, it is perishable particularly to run into rainy weather grain, and the peasant presses for a kind of miniature movable type dryer, and just even more important with the matching used hot-blast stove of miniature movable type dryer.The fuel of hot-blast stove uses biomass fuels such as crop straw, cattle and sheep animal manure, weeds, branch, promptly practices thrift and environmental protection.Existing hot-blast stove is vertical, and air intake and induced draught system and deduster can not be arranged on upper of furnace body, transport and move up very inconvenience, and thermal loss is big, and the thermal efficiency is low, and fuel consumption is big.
The utility model content
The purpose of the utility model is to overcome above-mentioned shortcoming, and a kind of compact conformation is provided, and transports, moves up conveniently, and thermal loss is little, and the thermal efficiency is high, and fuel consumption is few, the biomass fuel horizontal hot air furnace of energy savings.
The utility model biomass fuel horizontal hot air furnace is made up of fixed mount, body of heater, induced draught system and air inlet system.Wherein, The body of heater that is arranged on the fixed mount comprises that the body of heater that is provided with the hot blast import is outer; The body of heater intermediate layer that is positioned at the body of heater skin and keeps spacing distance; Be arranged on body of heater skin and body of heater intermediate layer front end and be installed in the combustion chamber on the fixed mount, the air inducing conical tube that is connected with the combustion chamber, the heat radiator assembly that is connected with the air inducing conical tube; Induced draught system comprises the induced duct that is connected with heat radiator assembly, the air-introduced machine that is connected with induced duct through the deduster tube connector, the deduster that is connected with induced duct through the deduster tube connector; Air inlet system comprises and is fixed on the body of heater skin air blast that its outlet is connected with the hot blast import, is arranged on that it exports the air intake cover that cooperates with blower inlet on the body of heater skin, and an end has air inlet, the blast pipe that the other end is connected with air intake cover.Wherein, what the lower end, combustion chamber was provided with the band ash discharging hole deposits grey chamber, combustion chamber and deposit between the grey chamber and be provided with fire grate, and the combustion chamber is provided with charge door and hot-blast outlet.Air inducing conical tube outer wall along the circumferential direction is provided with air inducing conical tube fin, and conical tube is formed behind the air inducing front cone pipe that the air inducing conical tube is connected with the combustion chamber by an end, an and end is connected with air inducing front cone pipe, the other end and air inducing that heat radiator assembly is connected.Blast pipe has the air intake vertical tube of air inlet by being positioned at induced duct outside one of which end, and an end is connected the air intake transverse tube composition that the other end is connected with air intake cover with the air intake vertical tube.Be provided with fin between induced duct and the air intake vertical tube, more can effectively utilize the heat of induced duct.Heat radiator assembly is made up of the fixed head at radiating tube and two ends.
The operation principle of the utility model biomass fuel horizontal hot air furnace is that bio-fuel adds from charge door, burning; Simultaneously, air-introduced machine work is under its suction; Air is introduced the combustion chamber from ash discharging hole; Accelerated combustion, the hot-air in the combustion chamber sucks in the deduster through radiating tube endoporus, induced duct, the deduster tube connector of air inducing conical tube, radiator, after dedusting, discharges.On the other hand, cold wind gets into from air inlet, gets into air blast through blast pipe, air intake cover, and at this moment, the cold wind of entering is carried out the heating first time by the waste heat of induced duct.The hot blast that comes out from air blast through body of heater outer with the body of heater intermediate layer between regional the time carry out the second time and heat.Afterwards, heat for the third time through heat radiator assembly.Afterwards, the 4th heating carried out in the zone between air inducing conical tube and body of heater intermediate layer, and be last, and the 5th heating carried out in the zone that gets between combustion chamber and the body of heater intermediate layer, and the hot blast after five heating is discharged from hot-blast outlet, gets into dryer.
The advantage of the utility model biomass fuel horizontal hot air furnace is compact conformation, and transportation and placement are convenient, and fuel source is extensive, and thermal loss is little, and the thermal efficiency is high, and Fuel Consumption is few.Be particularly suitable for hills area oven dry grain.
The specific embodiment
The utility model biomass fuel horizontal hot air furnace is made up of fixed mount 10, body of heater, induced draught system and air inlet system.Wherein, The body of heater that is arranged on the fixed mount 10 comprises the body of heater outer 17 that is provided with hot blast import 24; The body of heater intermediate layer 16 that is positioned at body of heater outer 17 and keeps spacing distance is arranged on body of heater outer 17 and body of heater intermediate layer 16 front ends and is installed in the combustion chamber 21 on the fixed mount 10, the air inducing front cone pipe 15 that is connected with combustion chamber 21; With conical tube 12 behind the air inducing that air inducing front cone pipe 15 is connected, the heat radiator assembly 11 that is connected with conical tube behind the air inducing 12; Induced draught system comprises the induced duct 7 that is connected with heat radiator assembly 11, the air-introduced machine 5 that is connected with induced duct 7 through deduster tube connector 4, the deduster 3 that is connected with induced duct 7 through deduster tube connector 4; Air inlet system comprises and is fixed on the air blast 1 that its outlet is connected with hot blast import 24 on the body of heater outer 17; Be arranged on the air intake cover 2 that its outlet cooperates with air blast 1 import on the body of heater outer 17; And one end the air intake vertical tube 8 of air inlet 6 is arranged; The one of which end is connected with air intake vertical tube 8, and the air intake transverse tube 9 that the other end is connected with air intake cover 2 is provided with fin 27 between induced duct 7 and the air intake vertical tube 8.Wherein, what 21 lower ends, combustion chamber were provided with band ash discharging hole 20 deposits grey chamber 19, and combustion chamber 21 is provided with fire grate 18 with depositing between the grey chamber 19, and combustion chamber 21 is provided with charge door 22 and hot-blast outlet 23.Conical tube 12 outer walls along the circumferential direction are provided with air inducing Taper Pipe fin 13 behind air inducing front cone pipe 15 and the air inducing.The heat radiator assembly 11 that looses is made up of heat pipe 26 and the fixed head 28 that is positioned at radiating tube 26 two ends.
