Abstract
The utility model relates to an automatic control device, in particular to a methanol adding automatic control device of nitro-cotton. The utility model aims at providing a methanol adding automatic control device of nitro-cotton which can correctly control the adding quantity of the methanol and can reduce the labor intensity of the operation personnel, which comprises a centrifugal and a wine storage tank, wherein the wine storage tank is connected with a top cover of the centrifugal through a pipeline, the pipeline is serially connected with an electromagnetic valve, the centrifugal is provided with a starting switch, the electromagnetic valve and the starting switch are respectively connected with a programmable controller, and the electromagnetic valve on the pipeline is controlled by the programmable controlled to open and to close so as to control the content of the methanol entering the centrifugal, so not only the content of the methanol can be precisely controlled, but also the labor intensity of the worker can be reduced.
Description
Technical field
The utility model relates to a kind of automatic control device, and particularly a kind of methyl alcohol of nitro-cotton adds automatic control device.
Background technology
In traditional nitro-cotton methyl alcohol adding technology, usually control its quantity of methyl alcohol by operator, its shortcoming is: the quantity of methyl alcohol of being added is by manual operation, personnel's working strength is big, and be difficult to control methanol content, methanol content is low excessively not to meet product requirement, and there is potential safety hazard in too high levels chemical instability.
The utility model content
The technical problems to be solved in the utility model provides a kind of nitro-cotton methyl alcohol interpolation automatic control device that can accurately add quantity of methyl alcohol and reduce labor intensity of operating staff.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of nitro-cotton methyl alcohol adds automatic control device, comprise whizzer, storage wine jar, described storage wine jar is connected with the top cover of whizzer by pipeline, its innovative point is: be in series with magnetic valve on described pipeline, on the described whizzer starting switch is housed, described magnetic valve is connected with programmable logic controller respectively with starting switch, and is connected with timing relay on described programmable logic controller.
Advantage of the present utility model is: by the electromagnetic valve switch closure on the Controlled by Programmable Controller pipeline, reach the content that control enters whizzer methyl alcohol, not only can accurately control the content of methyl alcohol, reduced working strength of workers again.
Description of drawings
Figure is the structural representation that nitro-cotton methyl alcohol of the present utility model adds automatic control device.
Embodiment
As shown in the figure, comprise whizzer 1, storage wine jar 2, described storage wine jar 2 is connected with the top cover of whizzer 1 by pipeline 3, series electrical magnet valve 4 on described pipeline 3, whizzer 1 is provided with starting switch 7, described magnetic valve 4 is connected with programmable logic controller 5 respectively with starting switch 7, also is connected with timing relay 6 on the described programmable logic controller 5.
In the time of work, magnetic valve 4 is in closure state, closed starting switch 7, whizzer 1 is started working, programmable logic controller 5 is accepted the unblanking timing relay 6 of starting switch 7, reach the time of setting when timing relay 6 after, programmable logic controller 5 sends signal and opens the magnetic valve 4 that is connected on the pipeline 3, methyl alcohol in the storage wine jar 2 enters whizzer 1 by pipeline 3, when timing relay 6 reaches predefined value once more, programmable logic controller 5 is closed magnetic valve 4, and the methyl alcohol of finishing whizzer 1 adds, and opens the quantity of methyl alcohol of control interpolation by the opening time of controlling described magnetic valve 4.
