flange that stops that granular material is overflowed.During work, charging tray rotates, and material is added on the charging tray and with charging tray from the charging aperture on the body of heater and rotates, and heating is rotated a nearly garden Zhou Houcong discharging opening and discharged.Be not difficult to find out, adopt this scheme can heat granular material, can make charging, heating, discharging is worked continuously, and material is uniformly distributed on the charging tray, material heating surface area big＜this material places container 〉, and homogeneous heating reach energy-conservation effect.Above-mentioned heater block can be the electroheat member that resistance wire is entwined, and also can be the nozzle of fuel injection nozzle or spray fuel gas.Above-mentioned structure with charging tray of flange is: the metal structure support body of garden annular, support body cross section are a rectangular channel, and trench bottom serves as a contrast into diatomite brick, and shop, top refractory brick constitutes card, and inboard embedding of card exceeds the card quarl, constitutes the charging tray flange.Scheme two: between body of heater and the charging tray, have two groups of sealing devices.Hot-air and stove circulate outward in the isolated stove of this scheme, in order to energy-conservation.The structure of this sealing device is: on the disk body of charging tray card inboard, load onto an annular tongue＜cross section is a rectangle 〉, the sand of packing in the groove, pack on week in garden, the card outside be with Baltimore groove refractory brick＜when granular material adds fashionable, can be full of in the Baltimore groove 〉, with two corresponding bodies of heater of cannelure on, each fixes an annular metal sheet, and makes it in the insertion groove.Scheme three: when granular material that discharging scraper plate ┈ then heats being housed on the body of heater forwarding discharging opening to, be subjected to stopping of discharging scraper plate, can flow out from discharging opening.The discharging scraper plate can be a hand-operated lifting ' ⊥ ' font scraper plate also can be electronic scroll casing shape rotor segment.Scheme four: some groups of claws are housed on the body of heater, and claw is contained in the top of charging tray, and stove when work can harrow into corrugatedly adding thermal material on the card, makes it to increase heated surface area, in order to energy-conservation.The structure of claw can be the straight shape grid type of grid, pears capitiform grid type or blade roll cylinder formula stirring-up rake.Scheme five: the claw in the scheme four, accomplish during installation: on week, the rake teeth on the adjacent claw staggers mutually in arbitrary garden that charging tray rotates.Installation can make material stir ┈ in stove and translate into the bottom being in the upper face material originally like this, can translate into upper face to the material that was in the bottom originally again.Material is heated evenly as a complete unit, shortens heat time heating time, in order to energy-conservation.Scheme six: with the charging tray rotation direction is positive direction, in the place ahead of charging aperture, height-adjustable charging scraper plate is housed on the body of heater, then enters the material in the stove, and its fabric thickness is more even.The structure of charging scraper plate can be manual or electric up-down ' ⊥ ' font scraper plate also can be a funnel board plug type scraper plate.Scheme seven: with the charging tray rotation direction is positive direction, and striker plate is equipped with at the outer rim place of the charging tray between charging aperture and charging scraper plate on the body of heater.The effect of this striker plate is: control the cloth width 1..2. prevent that powder from spilling outside the stove.The structure of striker plate: can be parallel-moving type ' Qian ' shape striker plate (horizontal fixed is in the body of heater side), also can be suspension type ' ⊥ ' striker plate (the body of heater top is fixed in suspension).Scheme eight: the striker plate in the scheme seven has the device of regulating its backgauge width.This scheme can be regulated the width of cloth on the charging tray.Regulating the cloth width is exactly in fact to regulate the heated surface area of material in stove, makes it and thickness of feed layer constitutes best heating (or roasting) operation system with the charging tray rotary speed, to reach maximum output and energy-conservation to greatest extent.The structure of adjusting device is an example with the manual rotary baffle plate: the striker plate place is installed at the body of heater top fixes a garden shape steel plate, steel plate center and garden week boring shape are with center ring flange with holes, the steel pole that striker plate is housed inserts in the centre bore, the steel pole of rotation striker plate also is locked in a certain hole of ring flange, can regulate the cloth width.Scheme nine (optimum structure of the present utility model): scheme one, two, six described structures install additional on the body of heater: A. discharging scraper plate.B. some groups of claws, the tooth on the adjacent set claw staggers
