Description
技术领域technical field
本发明涉及化工设备技术领域，具体地说是一种颗粒物料连续分级筛选气流干燥器。The invention relates to the technical field of chemical equipment, in particular to an air dryer for continuous classification and screening of granular materials.
背景技术Background technique
一般的，干燥设备又称干燥器和干燥机。用于进行干燥操作的设备，通过加热使物料中的湿分（一般指水分或其他可挥发性液体成分）汽化逸出，以获得规定含湿量的固体物料。干燥的目的是为了物料使用或进一步加工的需要。如木材在制作木模、木器前的干燥可以防止制品变形，陶瓷坯料在煅烧前的干燥可以防止成品龟裂。另外干燥后的物料也便于运输和贮存，如将收获的粮食干燥到一定湿含量以下，以防霉变。由于自然干燥远不能满足生产发展的需要，各种机械化干燥器越来越广泛地得到应用。In general, drying equipment is also called dryer and dryer. The equipment used for drying operation, the moisture in the material (generally refers to water or other volatile liquid components) is vaporized and escaped by heating to obtain a solid material with a specified moisture content. The purpose of drying is to meet the needs of material use or further processing. For example, the drying of wood before making wooden molds and wooden utensils can prevent product deformation, and the drying of ceramic blanks before calcination can prevent cracking of finished products. In addition, the dried materials are also convenient for transportation and storage, such as drying the harvested grains below a certain moisture content to prevent mildew. Since natural drying is far from meeting the needs of production development, various mechanized dryers are more and more widely used.
传统技术的厢式干燥器、转筒干燥器、流化床干燥器、喷雾干燥器功能单一，只能适合有限条件的干燥，不能良好的扩展应用范围。The traditional box dryers, drum dryers, fluidized bed dryers, and spray dryers have single functions, which can only be suitable for drying under limited conditions, and cannot expand the scope of application well.

本发明与现有技术相比所产生的有益效果是：The beneficial effect that the present invention produces compared with prior art is:
该颗粒物料连续分级筛选气流干燥器的设计集成了多室流化床和气流干燥为一体，并且利用流化床所产生的流化效果对颗粒物料进行流化状态时颗粒的流化高度不同进行模糊的粒度分级，其温度均匀，并可调节；传热速度快，处理能力大，停留时间可干预和调节，使颗粒物料的含水量降到极低，颗粒物料依靠进出口床层高度差自动流向出口，不需要输送装置，结构简单，可动部件少，操作稳定，能够实现连续化的大生产能力的操作。The design of the air dryer for continuous classification and screening of granular materials integrates multi-chamber fluidized bed and air drying, and uses the fluidization effect generated by the fluidized bed to perform different fluidization heights of the particles when the granular materials are in a fluidized state. Fuzzy particle size classification, the temperature is uniform and adjustable; the heat transfer speed is fast, the processing capacity is large, and the residence time can be intervened and adjusted to reduce the water content of the granular material to an extremely low level. Flowing to the outlet, no conveying device is needed, the structure is simple, the moving parts are few, the operation is stable, and the operation of continuous large production capacity can be realized.
颗粒粉尘级的物料分散悬浮于热风中，气固两相间扰动程度和接触面积都很大，其干燥的速度快，干燥的处理时间短，干燥效果明显，颗粒粉尘级的物料与热风并流操作，起到快速干燥，直接输送的目的。Granular dust grade materials are dispersed and suspended in the hot air, the degree of disturbance and contact area between the gas and solid phases are large, the drying speed is fast, the drying processing time is short, and the drying effect is obvious. The granular dust grade materials and hot air are operated in parallel , to achieve the purpose of fast drying and direct transportation.
尤其经过破碎机破碎或粉碎后的不同粒径的颗粒甚至混合了粉尘的物料，需要进行干燥处理，加入到料斗中，物料在流化罐塔的通径罐体内由栅板托起不会下漏，再经过热风的向上匀速吹送风干，大颗粒物料主要停留在大颗粒出料口层进行沸腾状的游离徘徊，中颗粒物料主要停留在中颗粒出料口层进行沸腾状的游离徘徊，小颗粒物料主要停留在小颗粒出料口层进行沸腾状的游离徘徊，控制热风风速形成流化干燥的动态游离徘徊的大颗粒出料口、中颗粒出料口、小颗粒出料口会相应的逃逸到大颗粒收集管道、中颗粒收集管道、小颗粒收集管道中流出，可实现连续化流化床式干燥，并且按照重力以及颗粒大小通过各个收集管道进行分级闭风收集；未逃逸到各个收集管道的粉尘状的物料则由热风向上沿变径塔体进行塔式流经的风干处理，处理过后的粉尘经过旋风分离器收集后可根据干湿度的情况选择经过卧式绞龙输送器回流到流化罐塔，或是直接卸料收集，旋风分离器顶部排出的细小微尘经过布袋滤尘器进行收集。如此不同位置的多级收集到的物料，粒径不同可实现连续式的处理，并且实现分级筛选最终获得干燥的物料。In particular, particles of different particle sizes or even materials mixed with dust that have been crushed or pulverized by the crusher need to be dried and added to the hopper. The materials are held up by the grid plate in the tank of the fluidized tank tower and will not fall down. After being blown upward by hot air at a constant speed, the large particle material mainly stays in the layer of the large particle outlet for boiling free wandering, and the medium particle material mainly stays in the layer of the medium particle outlet for boiling free wandering. The granular material mainly stays in the small particle outlet layer for boiling free wandering, and the hot air velocity is controlled to form a fluidized drying dynamic free wandering. The large particle outlet, medium particle outlet, and small particle outlet will respond accordingly. Escape to large particle collection pipes, medium particle collection pipes, and small particle collection pipes to flow out, which can realize continuous fluidized bed drying, and carry out classified closed-air collection through each collection pipe according to gravity and particle size; The dust-like material in the pipeline is air-dried by the hot air upwards along the variable-diameter tower body. After the dust is collected by the cyclone separator, it can be selected according to the dry humidity and returned to the Fluidized tank tower, or direct discharge collection, the fine dust discharged from the top of the cyclone separator is collected by the bag filter. The materials collected in different stages in different positions have different particle sizes, which can realize continuous processing, and achieve grading and screening to finally obtain dry materials.
该颗粒物料连续分级筛选气流干燥器设计合理、结构简单、安全可靠、使用方便、易于维护，具有很好的推广使用价值。The air dryer for continuous classification and screening of granular materials has reasonable design, simple structure, safety and reliability, convenient use and easy maintenance, and has good popularization and use value.
