Abstract
The utility model discloses a kind of wind pressure control system for complex machine; comprise programmable logic controller (PLC), fan frequency converter, blower fan, airduct, sensor, wind pressure transmitter and blast protective switch composition; it is characterized in that: programmable logic controller (PLC), fan frequency converter, blower fan are connected successively by circuit; blower fan UNICOM airduct; sensor is provided with in airduct; sensor, wind pressure transmitter are connected by circuit successively with programmable logic controller (PLC), and sensor, blast protective switch are connected by circuit successively with programmable logic controller (PLC).It is stable that the utility model reaches blast, simple to operate, the object of use safety.
Description
Technical field
The utility model is specifically related to a kind of control system, particularly a kind of automatical control system of blast.
Background technique
Complex machine in working order in, in its drying tunnel, the size of air intake pressure and air inducing pressure is most important, the two must mate according to the size of manufacturing technique requirent, and no person will make the material in drying tunnel produce the phenomenons such as shake, sideslip, causes significant impact to quality of product.
The complex machine sold in the market, air intake pressure-controlled generally adopts independent air inlet fan power frequency operation, then the way of manual tune ventilation door.Air inducing pressure then generally adopts each section to share an induced draught fan, induced draught fan power frequency operation, the then way of manual tune each section of air intake door.Therefore there is following shortcoming: 1. both, blast size does not have quantitative performance, the sensation completely by operator operates, and obviously there is defect error, very easily causes the two size not mate.2. above-mentioned air inlet fan and induced draught fan are operationally in power frequency operation state, and rotation speed of fan is fast, causes noise very big; 3. there is no blast protective gear, cause potential safety hazard.
Model utility content
The utility model provides a kind of wind pressure control system for complex machine, and object solves prior art problem, reaches blast stable, simple to operate, the object of use safety.
The utility model deal with problems adopt technological scheme be:
A kind of wind pressure control system for complex machine; comprise programmable logic controller (PLC), fan frequency converter, blower fan, airduct, sensor, wind pressure transmitter and blast protective switch composition; it is characterized in that: programmable logic controller (PLC), fan frequency converter, blower fan are connected successively by circuit; blower fan UNICOM airduct; sensor is provided with in airduct; sensor, wind pressure transmitter are connected by circuit successively with programmable logic controller (PLC), and sensor, blast protective switch are connected by circuit successively with programmable logic controller (PLC).
Described programmable logic controller (PLC) is connected by circuit with touch screen.
The beneficial effects of the utility model: 1. because blast sets fan pressure by the numeral of the sensor passes in airduct, therefore blast is stablized; 2., because blast adjustment is regulated by touch screen (man-machine interaction interface), simple to operate, fan noise is little; 3. blast protective switch is set, safe and reliable.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure: 1 programmable logic controller (PLC), 2 fan frequency converters, 3 blower fans, 4 airducts, 5 sensors, 6 wind pressure transmitters, 7 blast protective switches, 8 touch screens.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
A kind of wind pressure control system for complex machine as shown in Figure 1; comprise programmable logic controller (PLC) 1, fan frequency converter 2, blower fan 3, airduct 4, sensor 5, wind pressure transmitter 6 and blast protective switch 7 to form; programmable logic controller (PLC) 1, fan frequency converter 2, blower fan 3 are connected successively by circuit; blower fan UNICOM airduct 4; sensor 5 is provided with in airduct 4; sensor 5, wind pressure transmitter 6 are connected by circuit successively with programmable logic controller (PLC) 1, and sensor 5, blast protective switch 7 are connected by circuit successively with programmable logic controller (PLC) 1.
Programmable logic controller (PLC) 1 is connected by circuit with touch screen 8, forms man-machine delivery interface.
Wherein fan frequency converter is respectively air inlet fan frequency variator and induced draught fan frequency variator; blower fan is respectively air inlet fan and induced draught fan; airduct is respectively air intake pipe and induced air pipe; wind pressure transmitter is respectively air intake pressure transmitter and air inducing pressure transmitter, and blast protective switch is respectively air intake pressure protective switch and air inducing pressure protective switch.
The numerical value of required blast can be inputted in touch screen 8, and by this data transfer to programmable logic controller (PLC) 1, programmable logic controller (PLC) 1 collects the numerical value of current airduct 4 Wind pressure by wind pressure transmitter 6 simultaneously, programmable logic controller (PLC) 1 is by calculating, draw the frequency values of fan frequency converter 2, and this frequency values is transferred to air inlet fan frequency variator 2, frequency variator drives respective blower fan 3 with this frequency values, thus makes current wind pressure value equal the wind pressure value inputted in touch screen 8.Meanwhile, programmable logic controller (PLC) 1 is by gathering the state of blast protective switch 7, and state blast being less than to minimum blast lower limit is reported to the police.
Above-described specific embodiment; the purpose of this utility model, technological scheme and beneficial effect are further described; be understood that; the foregoing is only specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any amendment made, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
