Description
Technical field
The utility model relates to a kind of grain and oil machinery, relates in particular to a kind of Novel drum type drying equipment feed end mounting structure.
Background technology
Roller drier (claiming again rotary drum drier, rotary dryer etc.) is the drying machinery that adds heat-conduction-type in a kind of contact.In dry run, heat passes to its outer wall by the inwall of cylinder, through being attached to the food material being dried on cylinder outer wall face, the moisture evaporation on material, is a kind of manufacturing machine of continuous drying.
The rotating cylinder of roller drier is slightly to tilt and the rotating cylinder of energy, and wet stock enters from top, one end, and dry material is collected from other end bottom.Hot blast enters from feed end or discharge end, discharges from other end top.In cylinder, forward flight is housed, makes under material constantly takes up and spill in cylindrical shell turning course, it fully to be contacted, to improve drying efficiency and material is moved forward with thermal current.The thermal source of dried material is generally hot-air, high-temperature flue gas, steam etc.
The course of work of roller drier is: need in the blow tank of the dry feed liquid of processing by head tank person who lives in exile drum dryer, by film-distributing device make material thinly (membranaceous) be attached to cylinder surface, in cylinder, be connected with heating medium, food industry adopts steam more, pressure is generally at 0.2～6MPa, temperature is between 120～150 DEG C, material is conducted heat its hygroscopic water is vaporized by simple wall in cylinder rotates, roll letter and complete cloth film in a rotation period, vaporization, the processes such as dehydration, dried material is scraped by scraper, through helical feed to storage of finished products groove, finally pulverize or directly pack.The moisture evaporating in heat transfer, can pass through enclosed hood depending on its character, is incorporated into and in corresponding treating apparatus, traps dust or discharge.
Roller drier has the continuous feature of operation, can obtain uniform dry products; Roller drier is short drying time in the time of dried material, is generally about 7-30s, and dry product is the danger in high temperature not, is applicable to the dry of heat sensitive material, but that wall also likely produces is overheated; No matter dry high or low equal can being dried it of material slurry viscosity; The thermal efficiency is high; Because not remaining bottom product in drying machine, a small amount of material also can be dried; The operating parameter adjusting range of roller drier is wide, and is easy to adjust; In roller drier, be easy to cleaning, change purposes easy; Waste gas is not taken away material, does not therefore need with drying machine accessories such as cleaners.Roller drier is widely used in the dry of pasty material, all can be dried processing as dry yeast, antibiotic, lactose, starch slurry, natrium nitrosum, dyestuff, calcium carbonate and slops etc.
In grain and oil processing technique field, usually need raw material soften and be dried the plasticity to improve raw material, the base that crushing roll is shut out is thin and not broken, steams stir-fry, squeezing, leaching effect thereby improve.Therefore will use the equipment such as drying machine, in the last few years to grain and oil raw material soften desiccant more be revolving roll drying machine.
In Foodgrain and oilseed production, oil plant (for example soybean) will complete through pretreating process and extract technology the extraction of edible oil.In pretreating process, oil plant after preliminary screening and pressed compact in order to make material base reach ideal temperature and the humidity of following process, must be through this device processes of drying machine.In dryer drum assemble welding a large amount of heat-exchanging tube bundles, in heat-exchanging tube bundle, send into high-temperature steam by the air inlet pipe of discharge end, steam completes the heat exchange work with material in heat-exchanging tube bundle.Steam completes heat exchange meeting completely and condense into the water also outflow of inlet end that refluxes back in the pipeline tilting in theory.But inevitably having steam does not complete and condenses, in order to have discharged the steam condensing, need to air bleeding valve be installed at tube bank end, because tube bank is numerous, just need in each tube bank, air bleeding valve be installed, so just increase cost, and extremely inconvenience of operation, safeguard also very loaded down with trivial details.
In addition, be arranged in the compact spiral conveyer that can be arrived by elephant trunk roller drier porch by the complete material base of upper level processing unit processes, i.e. small-sized auger according to numerous pre-processing devices.Be delivered to cylindrical drier inside by this auger again.In current oil plant conveying technology, material base is not done to any processing, some material base can be because enter in roller drier after being squeezed into piece in course of conveying, and the material base of this bulk can not well contact with the heat exchanger tube of dryer inner, cause heat exchange efficiency to decline, energy consumption raises.
