The specific embodiment
Fig. 1 illustrates, and cylinder 6 and outer cylinder 5 in the present invention includes, automatic temperature control system, interior cylinder 6 and outer cylinder 5 all adopt uniform being welded on of some semicircle pipes to form the tube-sheet type heating arrangement on the cylindrical shell, and inside and outside cylinder has independently steam-heating system respectively; Should in cylinder steam-heating system consist of: interior cylinder inlet steam pipe 2 through steam distributor 10 with some in the steam pipe 2a of branch be communicated with, the branches steam pipes is connected with some semicircle pipes on the interior cylinder again correspondingly in some, the outlet of these some semicircle pipes is connected with some interior condenser pipe 2b of branch correspondingly, and some interior branches condenser pipe other end is communicated with interior drum outlet steam pipe 9 through outlet steam distributor 11; Should outer cylinder steam-heating system consist of: outer cylinder inlet steam pipe 3 through inlet steam distributor 10 with some outside the steam pipe 3a of branch be communicated with, some outer steam pipe 3a of branch are connected with the import of some semicircle pipes on the outer cylinder correspondingly, the outlet of some semicircle pipes is connected with some outer condenser pipe 3b of branch correspondingly, some outer branches condenser pipe through the outlet steam distributor 11 with outside drum outlet steam pipe 8 be communicated with; In, outer cylinder inlet steam pipe 2,3 and inlet steam distributor 10 between, and in, outer drum outlet steam pipe 9,8 are respectively arranged with the identical swivel joint of structure 4 with outlet between the steam distributor 11,7, rotary joint structure is: between outer tube 42 and overcoat 411 right parts bearing 43 is installed, place, outer tube (tumbler) upper bearing (metal) left side is provided with stationary ring 45 and rotating ring 44 successively, place, outer tube upper bearing (metal) right side is provided with gland 410, gland is screwed on the overcoat (fixture), and manage on 41 in outer tube spacing is arranged is enclosed within, the overcoat left part is provided with stuffing-box, asbestos are compeled root 47 snares on interior pipe 41, and be positioned at stuffing-box, clamp nut 48 is screwed on the stuffing-box, and be crimped on the urgent root of asbestos, with the bent sub 49(fixture that connects steam pipe) be screwed on the stuffing-box lateral surface, stuffing-box right side outer puts and is provided with the inlet tube 412(that connects another steam pipe referring to Fig. 3, and Fig. 3 illustrates, priming cup 46).
Among Fig. 1: 1, (cut-tobacco drier) support; 4, feed end swivel joint; 7, discharge end swivel joint; Interior condenser pipe 2b of branch among Fig. 1 and the outer condenser pipe 3b of branch promptly are corresponding steam (vapor) outlet drip pipes.The structure of the import among Fig. 1, outlet steam distributor 10,11 is basic identical, and (the inlet steam distributor has two covers: be the device that a pipe advances, some pipes go out to be existing commodity purchased; The outlet steam distributor has two covers: be the device that some pipes advance, a pipe goes out).
Automatic temperature control system is mainly by hot blast temperature RACS and hot blast wind speed RACS, inside and outside drum rotation speed RACS, inside and outside cylinder barrel temperature RACS, inside and outside cylinder condensed water discharging subsystem and material outlet contain mouthful rate RACS and form.
In the inside and outside cylinder barrel temperature RACS proportional divider is arranged, this proportional divider is arranged on before the inside and outside cylinder inlet steam pipe 2,3.
Fig. 4 is the two warm twin-roll tube-sheet type cut-tobacco drier barrel heater proportion control schematic diagrams of the present invention, not only independence but also relevant barrel heating controller of two on cylinder and outer cylinder in it comprises, and the control mode of each controller is identical.Each cylinder heating controller can be selected barrel temperature or cylinder steam flow pattern separately, should set corresponding barrel temperature or cylinder steam flow initial value after control model is determined, sets heater adjusting ratio and select the hand automatic control mode.Wherein heater adjusting ratio is the proportionality coefficient of the adjusting increment that calculates of PID controller, and the adjusting ratio sum of inside and outside two cylinders is 1.0.Wherein any one cylinder is selected the manual adjustments mode, and the adjusting ratio of this cylinder is invalid, if another cylinder is that its adjustment factor is 1.0 when moving regulative mode automatically, otherwise the adjusting ratio is invalid.Two so warm twin-roll tube-sheet type cut-tobacco driers have realized that barrel adds thermal control very flexibly, have enriched the process adjustments ability of equipment.
Among Fig. 5,21, the cut-tobacco drier main frame; 22, hot blast speed control; 23, hot blast temperature controller; 24, proportional divider; 25, steam flow controller; 26, steam flow controller; 27, outlet moisture content controller; 28, rotating cylinder rotational speed governor; 29, humidity discharging pressure controller; 30, air-heater; 31, storage heater; 32, barrel temperature controller; 33, barrel temperature controller; 34, moisture-eliminating blower.
Among Fig. 5, charging place of baking silk is measured inlet moisture content of cut tobacco and flow, and discharging place of baking silk is adopted Moisture Meter to carry out moisture (moisture content) to outlet leaf silk and measured.
The main feature of two temperature twin-roll tube-sheet type cut-tobacco driers: cut-tobacco drier main frame 1 has inside and outside two cylinders independently heater and condensate drain, a proportional divider is arranged before two heaters, can fix the temperature of a tube, automatically regulate another or link the automatic simultaneously temperature of regulating, realize diversification, the flexibility control of baking silk process, form the processing technology that specializes.Material enters cylinder by the cut-tobacco drier inlet, and the cylinder continuous equidirectional rotates, the tiny inclination angle of the oriented discharge end of cylindrical shell, and material is fallen inner core from urceolus, falls urceolus from inner core again, moves in circles, until tobacco-dryer exit.Internal and external cylinder can form different heating intensities, and material constantly replaces heat drying at inside and outside cylindrical shell, finally reaches the technological requirement of baking silk drying process.
The invention is not restricted to the scope of the specific embodiment, all innovation and creation of adopting the present invention's design are all at the row of this patent protection.
