The purpose of this utility model is to propose a kind ofly can send into the gas of discharging from hothouse that another hothouse continues to utilize and material carry out dry flow-through type drying machine under fluidized state.
The utlity model has charging aperture is set, the casing of discharging opening, casing is partitioned into several hothouses with deep bead, each hothouse is provided with air inlet, moisture exhausting port, vapor heat exchanger that is connected with air inlet and blower fan, transmitting device is set in the casing, transmitting device is driven by transmission mechanism, the utlity model has the dryer section that at least one is made up of 2-8 hothouse, each dryer section is provided with a humidity-discharging device, in same dryer section, arrange the preceding that the dehumidification tube of hothouse is connected with the humidity-discharging device of this section, the dehumidification tube of a hothouse is connected with the heat exchanger of previous hothouse thereafter.
Described transmitting device has rotating cylinder, cylinder inboard wall is fixed with flight, flight is triangular in shape, helical arrangement, helical angle is 1-5 °, and the position in the cylindrical shell flight between corresponding two hothouses is provided with annular striker plate, and cylindrical shell and flight are provided with many apertures, between casing and the cylindrical shell air inlet around be provided with the static-pressure chamber deep bead, the space in the casing is separated into static-pressure chamber and negative pressure cabin two parts.
The cylindrical shell of above-mentioned conveying device is downward-sloping, and the inclination angle is 1-5 °.
Be respectively equipped with opening at static-pressure chamber and negative pressure cabin bottom half in the above-mentioned conveying device, the opening below is provided with auger conveyor.
Figure one is known flow-through type drier structure diagrammatic sketch;
Figure two is the configuration diagram of embodiment;
Figure three is figure two vertical views;
Figure four is the A-A cutaway view of figure two;
Figure five is another embodiment diagrammatic sketch.
Below in conjunction with accompanying drawing the utility model is further described.
Figure two and the embodiment shown in the figure three have a drier structure of being made of dryer section two hothouses, the front end of casing 6 at it is provided with charging aperture 2, be provided with discharging opening 9 at its end, be provided with two hothouses 5 that are partitioned into deep bead 14 in the casing, 15, hothouse is provided with air inlet, moisture exhausting port, the vapor heat exchanger 17 that is connected with air inlet, and blower fan, humidity-discharging device 3 is by dehumidification tube, control valve, wet-emitting blower is formed, arrange the preceding that the dehumidification tube 13 of hothouse 5 is connected with humidity-discharging device 3, the dehumidification tube 12 of a hothouse 15 is connected with the heat exchanger 17 of previous hothouse thereafter; Conveying device of the present utility model runs through whole box body, drive the cylindrical shell rotation by drive mechanism 10, cylindrical shell is supported by wheel holding mechanism 11, conveying device has rotating cylinder 4 shown in the figure four, be fixed with 18-24 piece flight 18 in the cylindrical shell, present embodiment adopts 20, flight rotates synchronously with cylindrical shell, flight is triangular in shape, helical arrangement, helical angle is 1-5 °, present embodiment is selected 3 °, position in the cylindrical shell flight between corresponding two hothouses is provided with striker plate 25, striker plate interstitial hole 24 is a material channel, its big I is adjusted as required, cylindrical shell and flight are provided with many apertures 26, between casing and cylindrical shell air inlet around be provided with static-pressure chamber deep bead 21, space in the casing is separated into static-pressure chamber 19 and negative pressure cabin 23 two parts, for guaranteeing the transmission of material, cylindrical shell 4 is downward-sloping, the inclination angle is 1-5 °, present embodiment is selected 3 °, static-pressure chamber 19 and negative pressure cabin 23 bottom halves are respectively equipped with opening, and the opening below is provided with auger conveyor 20,22, auger conveyor is by transmission device 7 driven rotary, for preventing some material generation wall sticking phenomenon, at charge door pre-equipment for drying 1 is installed, in the pre-equipment for drying blower fan is set, thermal source or refrigeration source can provide hot-air or cold air as required.
When the utility model uses, material enter pre-equipment for drying 1 carry out predrying after, enter rotating cylinder 4 through charge door 2, drying source is a steam, hot-air is through each hothouse vapor heat exchanger 17, after 16 heating, be blown into hothouse casing static-pressure chamber 19 separately through blower fan separately from the drying machine sidepiece, enter in the flight with flight aperture 26 through cylindrical shell again and contact with material bed, rely on the air quantity and the blast of blower fan, material bed formation fluidized state, in the same dryer section, the hot-air that hothouse in back 15 is discharged enters previous hothouse 5, damp-heat air finally passes through the dehumidification tube 13 of top hothouse 5, humidity-discharging device 3 is discharged, material moves owing to the inclination of cylindrical shell and flight and the continuous rotation of cylindrical shell, advanced each hothouse successively by striker plate center material channel, and finally discharged from discharging opening 9, few parts of fine particle enters auger conveyor and exports from discharge end.
