Description
Technical field
The utility model relates to a kind of dryer, refers to the biomass fuel dryer especially.
Background technology
Dryer has rotary drum drying machine, three backhaul dryers, three-cylinder drier, polytypes such as dryer, directly-heated dryer intermittently.Relating to maximum in the production is rotary drum drying machine, and rotary drum drying machine is also referred to as drum drying equipment or rotary drum dryer, is to use the most common in the mining industry equipment and a kind of drying equipment widely.
Rotary drum drying machine has following plurality of advantages: 1. thermal efficiency height, and coal consumption reduces; 2. being suitable for multiple combustion furnace uses; 3. cost is low, and maintenance cost is convenient.4. can realize large enterprise's microcomputer CSRC management; 5, production capacity is bigger; 6, simple in structure, easy to operate; 7, fault is few, and maintenance cost is low.A lot of enterprises adopt rotary drum drying machine as the drying plant of biomass fuel one after another.
But present most of rotary drum drying machine is not suitable for being directly used in the oven dry of biomass fuel, the rotary drum drying machine working method is: dry wet stock is delivered to hopper by belt conveyor or bucket elevator, and the charger through hopper enters feed end by feeding tube then.The gradient of feeding tube is greater than the angle of crater of material, so that material flows in the drier smoothly.The drier cylinder is the rotor that and horizontal line slightly become inclination.Material adds from a higher end, and thermophore is entered by low side, becomes counter current contacting with material, thermophore and material is also arranged together and flows to into cylindrical shell.Along with the rotation material gravitate of cylinder runs to the end end of than.Wet stock moves forward in cylindrical shell in the process, has directly or indirectly obtained the heat of giving of thermophore, makes wet stock be able to drying, sends through belt feeder or conveying worm at discharge end then.At cylinder inboard wall flight is housed, its effect is that material is taken up and spread down, and the contact surface of material and air-flow is increased, to improve rate of drying and to promote material to advance.Thermophore generally is divided into hot-air, flue gas etc.After the thermophore drying device, generally need cyclone dust collectors that the material of being with in the gas is captured.Further reduce the tail gas dustiness as need, also should be through putting again behind sack cleaner or the hydrofilter.It is inhomogeneous that drying materials but appears in the oven dry that is directly used in biomass fuel, problem such as water evaporates is insufficient, and most of biomass fuel manufacturers have no alternative to this.
More domestic patent documentations disclose the technology of rotary drum drying machine, [patent No.] CN200720036850.2 for example, [title] rotating cylinder horizontal drying machine [notification number]: CN201032333, a kind of rotating cylinder horizontal drying machine is disclosed, there is one to comprise air blast, the high-boiling stove, elevator, feed bin, the frequency control belt feeder, tremie pipe, rotating cylinder, lifting blade, transmission system, dust pelletizing system, air-introduced machine, the discharging cover, blanking device, belt conveyer, lifting blade is " L " shape, be evenly distributed on the outer cylinder inwall of rotating cylinder, secondary lifting dispersing device also is housed on the inner cylinder outer wall of rotating cylinder; The large and small gear of transmission system is pick-off gear; Described dust pelletizing system includes cyclone dust collectors, air box impulse bag-type dust-precipitator two-stage dust removal.Problems such as this rotary drum drying machine is applicable to the oven dry of coal slime, and obtains good drying effect, and is inhomogeneous but drying materials still appears in the oven dry that is directly used in biomass fuel, and water evaporates is insufficient.
[patent No.] CN201120186045.4, [title] rotary drum drying machine [notification number]: CN202092428U, a kind of rotary drum drying machine is disclosed, comprise the dry kiln body, support and motor, motor is located on the support, the dry kiln body is obliquely installed on support by fixed bar, have the chute that can supply fixed bar to horizontally slip on the support, dry kiln body inside is equipped with driving wheel and driven pulley, be socketed with belt conveyor between driving wheel and the driven pulley, driving wheel is controlled by motor drives, and dry kiln body front end is connected with charging box, charging box is communicated with hot-blast stove, the charging box top has charge door, and charge door is connected with belt conveyor by blanking plate, and dry kiln body rear end is connected with feed box, feed box is connected with cyclone separator, and the cyclone separator outlet is connected with air-introduced machine by emptying pipe.Problems such as rotary drum drying machine has more flexibility, but is used for the oven dry biomass fuel, exists drying materials inhomogeneous equally, and water evaporates is insufficient.
The oven dry of biomass fuel is different from the oven dry of coal slime, and its is to temperature, charging rate of oven dry, and there is special requirement fuel use aspect, and existing rotary drum drying machine does not often reach such requirement.Therefore be necessary to invent a kind of rotary drum drying machine that carries out the biomass fuel oven dry that is specifically designed to, both kept the plurality of advantages of rotary drum drying machine, again biomass fuel is obtained good drying effect.
Summary of the invention
The purpose of this utility model is problems such as solution rotary drum drying machine drying materials is inhomogeneous, and water evaporates is insufficient, and a kind of living beings wood pellet dryer that carries out the biomass fuel oven dry that is specifically designed to is provided.
Living beings wood pellet dryer of the present utility model, comprise combustion fan, calcining furnace, conveying worm, main frame ,～deduster, temperature sensor, the other combustion fan that is provided with of calcining furnace, the heat output is connected main frame, and the main frame input is followed conveying worm, and output is followed belt conveyor and deduster, main frame and calcining furnace are equipped with temperature sensor, conveying worm is provided with speed setter, and calcining furnace is the wood waste combustion furnace, and calcining furnace is provided with combustion-supporting disconnected airduct.
Aforesaid speed setter is mounted in the main drive gear of the certain radius on the conveying worm.Calcining furnace is the manual combustion furnace of wood waste.Deduster is cyclone dust collectors.The main drive gear radius is 80 to 100mm.
Main frame and calcining furnace are equipped with temperature sensor, and the in-service monitoring temperature is convenient to control temperature; Changing the radius of conventional gears helical feed main drive gear as deceleration device, is a kind of more direct effective ways of deceleration, need not whole production technology is adjusted, and avoids other production link influenced; Adopt the cyclone dust collectors deduster as cleaner, can also carry out the whirlwind cloth, reclaim the biomass fuel pellet in the dust.Calcining furnace is that the wood waste combustion furnace has taken full advantage of the production obsolete material, improves timber utilization rate.
