The purpose of this utility model is to design a kind of new telescopic dryer, it can pass to hot flue gas and the hot blast that is produced by hot-blast stove respectively simultaneously in the interlayer of sleeve and tube, so that all be heated by baking feed or food, heating surface area is big, temperature is even, thereby improves the quality of oven dry thing, accelerates drying rate, and sleeve is pressed (pressure is very little) container for the nothing of logical hot blast and flue gas, therefore simple in structure, easily manufactured, low price.

Telescopic air flow dryer of the present utility model is by motor, decelerator, be loaded on a pair of gear on decelerator and the main shaft, sleeve, sleeve bearing, socket cover, sleeve center main shaft, be loaded on 2 above flights on the main shaft, main shaft is at socket cover place sealing device, the bearing block of supporting spindle, the bearing block bearing, the charging aperture of sleeve, discharging opening, the moisture outlet, shoot doors etc. are formed, flight on the described main shaft, its adjacent panels is orthogonal setting, of the present utility modelly be characterised in that described sleeve, which is provided with a hot-air channel straight-through with inner core, moisture outlet on it and this sleeve respectively quill to each end, in the described sleeve, interlayer is one and advances with flue gas between the urceolus, the interlayer that leads to hot flue gas that outlet is logical, exhanst gas outlet are the smokejack that a blast pipe inserts the dust removal water tank.

Operation principle of the present utility model is: pass to hot flue gas in the sleeve interlayer of dryer, and pass to hot blast (hot-air) in the sleeve, owing to this hot flue gas and hot blast come by special horizontal coal-fired hot-blast stove, the temperature of the two differs and is not too big, and hot blast can be regulated as required, and in design of the present utility model, considered to make exhaust gases passes and hot-air channel orthogonal again, therefore in the tube by in the middle of the baking thing is under the upset of flight and be heated simultaneously all around, especially hot blast directly with by the baking thing contacts, making by baking thing heating surface area increases greatly, and temperature is even everywhere, the institute so that the oven dry amount improve greatly, speed is accelerated greatly, thereby has improved productivity.

Embodiment
