Abstract
The invention relates to a control method and a device for a rotating valve of a slice delivering and drying system. The method comprises the steps: (1), connecting the rotating valve with a transducer, and controlling the rotating speed of the rotating valve by the transducer; (2) installing a level sensor in the storage hopper to obtain the signal of the level in the storage hopper immediately, and then feeding the signal back to the transducer through an optoelectronic isolator; (3) installing a controller between the rotating valve and the optoelectronic isolator so that the transducer increases the rotating speed of the rotating valve to fasten baiting when the level is lower than the preset level constant value, and the transducer reduces the rotating speed of the rotating valve to slow down the baiting when the level is higher than the level constant value. The control device comprises a transducer, a level sensor, an optoelectronic isolator and a controller. The invention ensures that the level of the storage hopper is constant in a certain position by controlling the rotating valve, thereby avoiding the condition that the storage hopper is full, solving the problems of rotating valve starting and stopping and circulation fan energy consumption, and reducing the difficulty of product quality control.
Description
Technical field
The invention belongs to the chemical fibre field, particularly relate to control method and device that the revolving valve of drying system is carried in a kind of chemical fibre section.
Background technology
The conveying of section is one of important step of chemical fibre production.Section carries drying system to generally comprise feeder hopper, revolving valve, hopper, and revolving valve is obtained specific rotating speed by Frequency Converter Control, and its upper end taps into hopper, following termination hopper.Because the revolving valve rotating speed fixes, when running into spinning winding off-position fault or other and reduce the section consumption, will cause feed bin completely to be expected and make revolving valve shut down, treat to open again again after material level descends; In addition,, must strengthen the air quantity of circulating fan, so, not only consume energy but also strengthened the difficulty of quality control in order to make when material level is bought securities with all one's capital section be unlikely to tie sheet.
Summary of the invention
Technical matters to be solved by this invention is in order to overcome the deficiencies in the prior art, a kind of control method of revolving valve is provided, adopt this method can regulate the blanking amount of revolving valve automatically, make the material level in the feed bin be in a certain constant position all the time, the situation of avoiding feed bin completely to expect takes place.
The device that the present invention also will provide a kind of above-mentioned control method to adopt.
For solving above technical matters, a kind of technical scheme that the present invention takes is:
A kind of control method of revolving valve of the conveying drying system of cutting into slices, this method comprises the steps:
(1), revolving valve is linked to each other with frequency converter, control the rotating speed of revolving valve by frequency converter;
(2), level sensor is installed in feed bin, obtain the signal of material level in the feed bin immediately, give frequency converter by photoisolator with described signal feedback then;
(3), between revolving valve and photoisolator, controller is set, make when material level is lower than default constant material level value, the rotating speed that frequency converter improves revolving valve to be accelerating blanking, and when material level was higher than described constant material level value, frequency converter reduced the rotating speed of revolving valve with the blanking of slowing down.
Described controller is preferably Programmable Logic Controller.
Another technical scheme of the present invention is: a kind of control device of revolving valve of the conveying drying system of cutting into slices, this control device comprises the frequency converter that is connected with the motor of revolving valve, the level sensor that the material level in the feed bin is responded to, photoisolator, the controller that input end is connected with the output terminal of level sensor, the output terminal of described photoisolator is connected with the input end of frequency converter, and the input end of controller is connected with photoisolator, output terminal is connected with frequency converter.
Because the utilization of technique scheme, the present invention compared with prior art has following advantage:
Frequency converter is arrived in controlling level signal immediate feedback in the feed bin, frequency converter is made a response to signal: when material level is higher than a certain predefined material level value, reduce the rotating speed of revolving valve, reduce the blanking amount, when material level is lower than a certain predefined material level value, improve the rotating speed of revolving valve, strengthen the blanking amount, so, the situation that can avoid feed bin completely to expect takes place, solve the problem of revolving valve start-stop and circulating fan power consumption, reduced the difficulty of production quality control.
