The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.Shown in accompanying drawing 1,2, on the ventilation shaft 1 that pipe tobacco wind send, increase anemobiagraph 7, anemobiagraph 7 has the numeral demonstration and carries analog quantity (4～20mA) outputs, and the return air wind speed changed into the materail tube wind speed, at pipe tobacco selection by winnowing case 2 places display gauge head is installed and is accurately shown air speed data, the 1336PLUS II frequency converter 12 of AB company is selected in blower fan 6 frequency conversion transformations for use.1336PLUS II frequency converter 12 provides very simple parameters setting and operation, control method novelty, applying flexible and function brilliance.
1336PLUS II frequency converter 12 is realized the control to motor by workshop existing equipment control bus 13 and PLC9 communication, can read a large amount of procedure parameters such as frequency converter status word, running frequency, frequency converter temperature and current of electric; Simultaneously, also realized to motor remote activation, stop the real-time control with frequency.Use network communication to have following advantage than traditional control mode: wiring quantity reduces, the data of gathering frequency converter are many, and the device control network that antijamming capability is strong is used for being connected between simple, industrial equipment (as frequency converter, sensor etc.) and the sophisticated equipment (as controller).Measured control domain technology, this open network provides the interoperability between many vendor equipment, comprising the communication of 1336PLUS II frequency converter 12.Pipe tobacco wind pressure fan control is connected with 1756-DNB template in the main control PLC pedestal by 1203-GK5 communication module 11 with frequency converter among the utility model embodiment, carries out communication with ControlLogix5555.More than 300 parameter of 1336PLUS II frequency converter inside can be watched or revise to this kind control mode by corresponding programming software, can obtain by the data acquisition of equipment control bus network as the electric current of motor, temperature, rotating speed etc., only need that a long-range change parameter get final product on control room touch-screen or monitoring equipment.Pipe tobacco wind pressure fan 6 has obtained intelligent control by 1336Plus II frequency converter 12.Blast system also has been incorporated on the original centralized control system in workshop by this transformation simultaneously, has reduced manual intervention, has improved automation degree of equipment.
Pipe tobacco wind pressure fan adopts Frequency Converter Control after the system reform, the wind speed of expectation is set on monitoring equipment by operating personnel, carry out the PID computing by PLC, operation result is exported to frequency converter by equipment control bus network, the control rotation speed of fan, come online detection actual wind speed by anemobiagraph then, thereby the data that record are passed to the rotating speed that PLC revises blower fan in real time, carry out accurate, the control flexibly of wind speed.
After the system hardware transformation is finished, in that we have been the contrast experiment to the broken rate of pipe tobacco and the relation between the wind speed on the new air-transport system, experimental selection pipe tobacco wind send between speed 15m/s-22m/s and carries out, and along with the increase of conveying air velocity, the degree of fragmentation of pipe tobacco is to increase rapidly.Otherwise conveying air velocity is low more, the degree of fragmentation relative ideal of pipe tobacco.But in experiment, when selecting conveying air velocity＜15m/s for use, have sometimes a little qualified pipe tobacco can be in selection by winnowing disallowable settling.So conveying air velocity the best is selected scope 〉=15m/s for use, but for keeping the stability of air-transport system, overcome the influence because of the big minor swing of pipe tobacco chopping in the production process, for production safety and convenient operation and control, getting conveying air velocity 15.5m/s-16.5m/s is optimal value.In test, the percentage of damage of not finding pipe tobacco is along with the change of delivery ratio has obvious variation.The pipe tobacco air-transport system is after adopting PLC technological transformation and parameter optimization; system obviously speeds the adjusting time; because it is suitable that wind send parameter to select; whole air-transport system operating ratio is more steady; when producing system change; also can in time reach the requirement of operation wind speed, because of the blast system fault effects obviously reduces downtime.Particularly gratifying is pipe tobacco wind sent to transform to be incorporated in the centralized control system of workshop the back operating personnel and can easily to regulate wind according to practical condition and send speed, found out the control experience of a cover oneself aborning.The material situation of picking out from the selection by winnowing chamber: how, pipe tobacco had lacked, and wind send the moisture loss at two also to fluctuate little than before before foreign material and stalk head were transformed.Production efficiency and tobacco quality are greatly improved.Because air-transport system also has numerous cigar mills to use at home, also have other strength to carry as tobacco leaf, offal, expansion thread, thereby apply the PLC converter technique, transform original system, and constantly grope to sum up best wind and send parameter can obtain tangible economic benefit and social benefit.
