Selection by winnowing wind send the air quantity humidity automaton of equipment
Technical field
The utility model relates to a kind of cigarette process equipment, refers to that especially cigarette (stalk) silk selection by winnowing wind send in the equipment in the cigarette throwing processing, is used to control the automaton of air quantity humidity.
Background technology
The air quantity automaton that selection by winnowing wind send equipment in the prior art as shown in Figure 1, it connects the shake air flotation table 6 ' of groove 5 ' of charging by one and connects a blast pipe 4 ', an exhaust duct 1 ' in regular turn, one blanking gas lock 7 ' connects this blast pipe 4 ' and exhaust duct 1 ', being provided with a dedusting filter screen 3 ' between described blast pipe 4 ' and the exhaust duct 1 ' forms, establish on the described blast pipe 4 ' and wind speed detecting sensor 9 ', described exhaust duct 1 ' is provided with an automatic control storm door 2 ', one PLC control module and connects wind speed detecting sensor 9 ' and automatic control storm door 2 '.Though this equipment can measure present selection by winnowing wind and send the size of air quantity in the equipment and control automatically, can't measure the humidity that present selection by winnowing wind send air quantity in the equipment; And cigarette (stalk) silk selection by winnowing wind send process moisture loss difference greatly when seasonal variations, ambient temperature and humidity variation.When cigarette (stalk) silk selection by winnowing wind sent the humidity of air quantity in the equipment to change, system can't make corresponding adjustment, the poor stability of process technological parameter.
The utility model content
At the deficiencies in the prior art part, the purpose of this utility model is to provide a kind of raising cigarette (stalk) silk selection by winnowing wind to send stay-in-grade air quantity humidity automaton in the process, this device guarantees the stable of process technological parameter by introducing the control of cigarette (stalk) silk selection by winnowing wind being sent process air quantity humidity.
For achieving the above object, technical solutions of the utility model are:
Selection by winnowing wind send the air quantity humidity automaton of equipment, its mainly by an air flotation table connect a blast pipe in regular turn, an exhaust duct is formed, establish on the described blast pipe and the wind speed detecting sensor, described exhaust duct is provided with an automatic control storm door, it is characterized in that: described blast pipe is connected with that a steam applies pipeline and a dry wind applies pipeline, and on this blast pipe, also being provided with a Temperature Humidity Sensor, a PLC control module connects Temperature Humidity Sensor, dry wind applies pipeline and steam applies pipeline.
Described steam applies pipeline and is provided with a steam control valve, and this steam control valve connects the PLC control module; Described dry wind applies pipeline and is provided with a dry damper regulator, and this drying damper regulator connects the PLC control module.
The usefulness of technique scheme is:
The utility model has been introduced and has been sent in the process automaton to air quantity humidity to cigarette (stalk) selection by winnowing wind on former prior art selection by winnowing wind send in the equipment the size of air quantity and the technical construction controlled automatically.This automaton send air quantity humidity and cigarette (stalk) silk moisture content in the equipment to be optimized combination to cigarette (stalk) silk selection by winnowing wind, obtains best technology controlling and process point; This automaton is easy to operate, as long as input suits on the control display screen the humidity desired value upper limit, humidity desired value lower limit just can be realized the stable control of air quantity humidity.By cigarette (stalk) silk selection by winnowing wind being sent the control of process air quantity humidity, avoid because of seasonal variations, cigarette (stalk) influence that selection by winnowing wind send process water to divide fluctuation to bring more greatly when ambient temperature and humidity changes; Above-mentionedly send the control of process air quantity humidity by introducing, guarantee the stable of process technological parameter, improve the stability that cigarette (stalk) selection by winnowing wind send procedure quality cigarette (stalk) silk selection by winnowing wind.

The specific embodiment
The utility model now is described in conjunction with the accompanying drawings and embodiments.
Selection by winnowing wind as shown in Figure 1 send the air quantity humidity automaton of equipment, it mainly connects the shake air flotation table 6 of groove 5 of charging by one and connects a blast pipe 4, an exhaust duct 1 in regular turn, one blanking gas lock 7 connects this blast pipe 4 and exhaust duct 1, is provided with a dedusting filter screen 3 between described blast pipe 4 and the exhaust duct 1 and forms.Establish and wind speed detecting sensor 8 on the described blast pipe 4, described exhaust duct is provided with an automatic control storm door 2.The utility model has been introduced the automaton of moisture detection device to air quantity humidity, it also is provided with a Temperature Humidity Sensor 9 on described blast pipe 4, and connect on this blast pipe 4 that a steam applies pipeline 10 and a dry wind applies pipeline 12, described steam applies pipeline 10 and is provided with a steam control valve 11, described dry wind applies pipeline 12 and is provided with dry damper regulator 13, one PLC control modules 14 connection Temperature Humidity Sensor 9, steam control valve 11 and dry damper regulators 13.Described Temperature Humidity Sensor 9 is installed in steam along the air motion direction and applies after pipeline 10 applies pipeline 13 with dry wind.This PLC control module 14 is by pid control circuit control steam control valve 11 and dry damper regulator 13.The air dielectric that steam applies in the pipeline 10 adopts through post-decompression steam, and the air dielectric that dry wind applies in the pipeline 12 adopts the air-conditioning dry wind.
As shown in Figure 2, the PID control system adopts the PLC control module 14 that itself carries in the selection by winnowing blast system, uses its functional language within it in portion's functional block and designs pid control circuit and control; Introduce moisture detection device adopt the duct type humidity transmitter, it mainly is made of a Temperature Humidity Sensor 9, it feeds back to PLC control module 14 by detecting ducted humidity.
PLC control module 14 when goal-setting value high tolerance that humidity value is imported in greater than man-machine interface, is opened steam control valve 11 and is also carried out PID control, closes dry damper regulator 13 simultaneously; Prescribe a time limit when humidity value is lower than under the goal-setting value franchise of importing in the man-machine interface, open dry damper regulator 13 and carry out PID control, steam off control valve 11 simultaneously.
Steam control valve 11 adjusts steam control valve 11 apertures or dry damper regulator 13 throttle openings for electropneumatic transducer and pneumatic actuator equipment integrating according to the output current control signal of pid control circuit respectively with dry damper regulator 13, automatically adjust, send the purpose that air quantity humidity is controlled automatically in the equipment thereby reach cigarette (stalk) silk selection by winnowing wind.
