Abstract
The invention discloses a staggered bed drying device and method. A casing is a vertical type rectangular box; a stock bin and moisture outlets are formed in the upper portion of the casing; a finished product conveying device is arranged at the lower portion of the casing; multiple layers of staggered beds are arranged inside the box; a material falls on the staggered beds from the stock bin; cylinder sets drives movable beds to reciprocate; the material on fixed beds is scraped and conveyed onto the next group of fixed beds; hot air enters hot air circular pipes with three rows of holes and fixed bed square pipes with two rows of holes; then the hot air is sprayed onto the material uniformly, and direct drying is carried out; moisture produced by drying passes through empty-layer channels located below square pipe fixed beds and above the hot air circular pipes, flows towards the front side and the back side of each channel into moisture channels and is exhausted out of the moisture outlets; when the material reaches the moisture content which should be lost in the current layer, the material is conveyed to the next stage of staggered beds and dried continuously; and the same operation is repeated till the material is dried to reach the required moisture content.
Description
Technical field
The present invention relates to a kind of staggered bed drying unit and method, belong to drying materials field.
Background technology
Have several to granule materials and powder furnace drying method at present, simultaneously Shortcomings part, rotary kiln, box kiln, fluid bed are dried, be only applicable to granule materials, the thermal efficiency is low, and generally about 30%, fluid bed heat efficiency is slightly higher, but consuming electric power is comparatively large, oven dry cost is high; Airflow drying, flash evaporation drying are comparatively applicable to powder material, advantage, the thermal efficiency is higher by about 50%, and unit production capacity is large, but, the equipment that subsequent product is collected is complicated, evaporation capacity per hour 3 tons of id-motors 350 kilowatts, and power consumption is high, investment is large, production environment dust is large, and product moisture can not adjust, and oven dry cost is higher; Rake is dried, vertical disc is dried, be applicable to powder, can adjust the moisture of product, dry with conduction pattern heat exchange, only have material to contact disk and just can be heated, the thermal efficiency is low, thermal source steam 150 DEG C or conduction oil, dryer becomes pressure vessel, has potential safety hazard, and dryer cost is high, maximum problem is that unit production capacity is too little, maximum unit hour evaporation capacity 0.9 ton.
Summary of the invention
Object of the present invention is for the deficiency of above-mentioned existing furnace drying method, a kind of staggered bed drying unit and method are provided, both be applicable to granule materials and be also applicable to powder material, the thermal efficiency is high, and configuration electric energy is little, and unit production capacity is large, the little dust collection device of follow-up dust is simple, product moisture after oven dry can adjust arbitrarily, is that conduction heat exchange and the mode that combines of heat convection carry out drying, and the caking of the drying course bed that interlocks has shearing pulverization.
The present invention seeks to by following technical proposal realize: described device is vertical rectangular shape casing main body, top is provided with raw material cabin and moisture outlet, bottom is provided with inclined-plane finished product hopper and conveyer, main body left and right side is provided with multistage layer hot-air channel and hot-wind inlet from top to bottom, main body trailing flank is provided with the cylinder component that multistage layer is from top to bottom connected with pulldown bed, multistage layer angle steel component pulldown bed and slideway is provided with in main body, be provided with the square tube assembly fixed bed of multistage layer with two rounds, be provided with multistage layer to arrange with the warm-air pipe of three rounds, in main body bottom a small amount of which floor be provided with square tube component activity bed and slideway.The steps include: that the material that will dry adds feed bin, drop on pulldown bed and fallen by pulldown bed angle steel spacing on the fixed bed that is made up of the square tube with two rounds, cylinder component drives pulldown bed reciprocating action, material in fixed bed square tube is scraped spacing uniform between square tube, fall on fixed bed that next group pulldown bed and being fallen by pulldown bed angle steel spacing is made up of the square tube with two rounds, its bed depth is to the upper edge of hot blast pipe, and hot blast pipe is embedded in inside the bed of material, hot blast enters main body both sides hot-air channel header by hot-wind inlet, enter the fixed bed square tube of band three round hot blast pipe and band two rounds again, material directly contacts its surface and carries out heat by conduction to material, hot blast simultaneously with three round hot blast pipes, evenly spray from three rounds and from bottom to top penetrate the bed of material and directly dry, fixed bed square tube with two rounds evenly sprays from two rounds, be ejected on material below and directly dry, pipe, the hole of square tube is arranged does not exist clogging down, dry produce moisture below square tube fixed bed with hot blast pipe above dead level passage flow to moisture passage in both sides forwards, backwards, exported by moisture and discharge, according to the time angle steel pulldown bed reciprocating action set once, physics is fallen the next level of same structure, action so successively, wet stock, by the raw material cabin product feed bin falling lower body part gradually, realizes the object to drying materials, for meeting the different requirements to drying rear product moisture, the adjustable pulldown bed action time once, different product water content requirement just can be met, in main body, the pulldown bed of which floor staggered bed of bottom adopts board-like pulldown bed to replace angle steel pulldown bed, because material from top to bottom moisture reduces gradually, material fluidity is larger, the gap of angle steel pulldown bed and fixed bed is comparatively large, and material does not reach moisture requirement and just flows to finished product bin, admittedly utilize board-like pulldown bed cover plate to carry out control gap, when material reaches moisture requirement, board-like pulldown bed can reciprocating action, falls next level, until dry predetermined material moisture requirement.
