Description
Technical field
The present invention relates to a kind of friction fluid bed dryer, belong to the plant equipment field.
Background technology
Along with China's industrial expansion, various industrial products adopt drying machine to realize dewatering process in a large number, and widely used drying machine is broadly divided into fluid bed dryer, roller drier, vacuum drier etc.The operation principle of fluid bed dryer is by vibrator the whole bed body to be vibrated, and realizes the moving process of material from the charging aperture to the discharging opening.The hot blast of dried material is to keep watch by air blast and ventilation shaft to send into heat exchanger, enters in the fluid bed casing again.Hot blast produces certain blast in casing, pass the air distribution plate that is installed on the casing, then material is heated, and simultaneously the material moisture evaporated is taken out of casing by the air inducing pipeline, enters dust arrester, final deaeration and moisture.
The subject matter that present widely used fluid bed dryer exists:
One, vibrating device must be installed, noise is big, and the bed body easily shakes and splits, and material moves inhomogeneous, and discharging speed is difficult to control, needs the design vibration absorber between casing and base.
Two, external air-blast device energy consumption is big.External air-blast device is sent into hot blast in the lower part box by ventilation shaft, because pipeline is long, elbow is many, has increased the resistance of wind, and the wind energy loss is big, utilization rate is low, and air-blast device is external, and the plant area that takies is big.
Three, traditional fluid bed is to carry out discharging by vibration fully, and namely vibrator makes the vibration of whole bed body material with bed body play, realizes the discharging process.Problem is the granular size inequality of material, and water content and weight are also uneven, and granule is easily dry, and is blown up easily, and bulky grain is difficult for dry and weighs.Under vibrational state, bulky grain walks fast, and granule loses time, and forms slow that granule goes out, and fast bad phenomenon and production demand that bulky grain goes out are just in time opposite.
Four, hot blast flows unequal in casing, wind can not evenly be discharged from air distribution plate, material can not be seethed with excitement comprehensively, dead bed phenomenon appears easily, that is to say under certain blast, as the material too many or that add that material adds occurs and have certain adhesive, occurring material easily and can not be blown up or be bonded at (air distribution plate) on the bed surface, this phenomenon is named dead.Dead bed occurs, needing manually lives the material rake carries out drying, particularly often occurs dead bed when debugging, is difficult to enter ordinary production.
Summary of the invention
The technical problem to be solved in the present invention is: the evenly friction fluid bed dryer of energy-conservation and high efficiency of a kind of friction, low noise, dry materials degree is provided.
The technical scheme that the present invention adopts for its technical problem of solution is: the friction fluid bed dryer, comprise base, casing, heat exchanger, air-introduced machine and deduster, casing is installed on the base, the air outlet of casing connects air-introduced machine, air-introduced machine connects deduster, it is characterized in that: be provided with air distribution plate in the casing and be divided into upper box body and lower part box by air distribution plate, lower clapboard is set in the lower part box, lower clapboard is separated into a plurality of air compartments with lower box, corresponding lower clapboard is provided with upper spacer in upper box body, last ventilating duct is arranged at the upper box body top, between the two adjacent lower clapboards air-blast device is set, and air-blast device connects heat exchanger.
Adopt the friction fluid bed dryer of this structure, be provided with lower clapboard in the lower part box, lower clapboard is divided into a plurality of air compartments with lower part box, and air-blast device is installed respectively in each air compartment, can regulate air quantity respectively according to granular size and the water content difference of material, play energy-saving effect, obtain qualified dried material.The main effect of upper box body is to form a hot blast chamber, and material is in the indoor drying of carrying out of hot blast, and the upper spacer that is provided with in the upper box body is divided into upper and lower ventilating duct with the ventilating duct in the upper box body, and last ventilating duct plays main draught effect.
Be connected by wind gathering cover between described air-blast device and the heat exchanger, from the heat exchanger to the air-blast device, the bore of wind gathering cover increases progressively.Air-blast device blasts outside air in the lower part box and by heat exchanger and converts gas to high-temperature gas, and gas is got back in the lower part box by wind gathering cover, and in this process, gas can be formed turbulent flow by unexpected acceleration, therefore can improve air inflow.Described air-blast device comprises wind wheel, motor and driving-belt, and wind wheel is built in the lower part box, and motor is connected with wind wheel by driving-belt.The employing wind wheel is built in the structure in the lower part box, removed original air blast spiral case, wind wheel is directly installed in the lower part box, lower part box replaces the air blast spiral case, wind wheel has removed original air supply duct directly from heat exchanger air inducing, has reduced floor space, reduce energy consumption, reduced manufacturing cost simultaneously.In addition, corresponding wind wheel is provided with the wind wheel installing hole in the outside of lower part box, is convenient to the I﹠M of wind wheel.
Corresponding upper spacer arranges adjustable plate in upper box body, adjustable plate is positioned at upper spacer top and hinged by axle and upper box body, one side of axle is fixedly connected with adjusting rod, the corresponding adjusting rod in the upper box body outside is provided with location-plate, be distributed with the location adjustment hole on the location-plate, adjusting rod and location-plate are fixed by alignment pin, and alignment pin is arranged in arbitrary location adjustment hole.Regulate the rotational angle of adjustable plate by adjusting rod, thereby regulate the air quantity by last ventilating duct and following ventilating duct, assist discharging, thereby regulate the water content of material, can reach the fine particle dried effect that goes out earlier earlier, because the fine particle water content is few, fast drying, light specific gravity is easily blown by hot blast.
Described air distribution plate top is provided with poking device, and poking device comprises switch-plate, two mutual parallel chain and installing racks, and installing rack is fixed in the upper box body, and chain is installed on the installing rack, between two chains switch-plate is installed, and chain connects drive unit.Between two chains switch-plate is installed, is driven chain by drive unit and rotate, chain drives the switch-plate rotation simultaneously, and it is mobile at air distribution plate that switch-plate can promote material.The translational speed that the velocity of rotation of adjustment chain can be regulated material realizes balanced and discharging reposefully, and drive unit can drive chain and rotate and reverse, thereby realizes that switch-plate drives material and moves back and forth at air distribution plate, has avoided dead phenomenon.
The sidewall of described upper box body is provided with peep hole.The setting of peep hole is convenient to observe state and the dry run of material.
The invention has the beneficial effects as follows:
Upper spacer and adjustable plate are set in the upper box body, by upper spacer the air channel are divided into ventilating duct and following ventilating duct, and can regulate the air quantity of ventilating duct and following ventilating duct by adjustable plate according to the kind of material, reach the discharging effect of equilibrium; Dividing plate is set in the lower part box, and air-blast device is set between adjacent separator, can contain the moisture difference according to material and regulate air quantity respectively, obtain qualified material, and reduced various ventilation shafts and elbow, have energy-saving effect; Be provided with poking device and replace original vibrating device, improve machine life, avoided dead bed phenomenon.
