Abstract
The invention relates to an automatic gas flow control device for a wire drawing furnace. The device comprises the wire drawing furnace which is sequentially connected with a pressure measuring device, a converter, a programmable logic controller (PLC) and a main control computer, wherein a measuring probe of the pressure measuring device is arranged in the wire drawing furnace. The automatic gas flow control device for the wire drawing furnace has a simple structure and a reasonable design, reduces manual intervention to adjust gas flow in the wire drawing furnace and realizes automatic adjustment; and the air pressure change in the wire drawing furnace is monitored in real time, and equipment is more intelligent.
Description
Technical field
The present invention relates to a kind of fiber drawing furnace gas flow automatic control device in the optical fiber manufacturing.
Background technology
In optical fiber production, gas flow does not generally change in the fiber drawing furnace usually, when the gas field changes in the stove, is by unusual passive the feeding back of optical fiber quality, is handled by the manual intervention adjustment again, certain hysteresis quality is arranged, and caused defective products to produce.
Technical scheme
Goal of the invention: the objective of the invention is in order to solve above-mentioned the deficiencies in the prior art, the fiber drawing furnace gas flow that a kind of mechanism is simple and level of automation is high automatic control device is provided.
Technical scheme: fiber drawing furnace gas flow automatic control device of the present invention, its objective is such realization: a kind of fiber drawing furnace gas flow automatic control device, comprise fiber drawing furnace, be connected with stress measuring device, transmitter, PLC controller, master control computer in turn with fiber drawing furnace.
Described stress measuring device comprises pressure transmitter or tensimeter.
The probe of stress measuring device is installed in the fiber drawing furnace, be used to monitor the variation of furnace pressure, when prefabricated rods welding position enters in the process of fiber drawing furnace, because the variation in rod footpath, gas field in the fiber drawing furnace changes, change by pressure transmitter or tensimeter detecting pressure, pass the signal to the PLC controller by transmitter, the furnace pressure of monitoring reflection in real time changes on the master control computer, the pid algorithm of PLC controller utilization is simultaneously regulated the MFC gas flow automatically, to reach the stable of gas field and thermal field in the fiber drawing furnace, guaranteed the high quality that optical fiber is made.
Beneficial effect: fiber drawing furnace gas flow automatic control device of the present invention is simple in structure, reasonable in design, reduces manual intervention and adjusts gas flow in the fiber drawing furnace, realizes regulating automatically; The fiber drawing furnace internal gas pressure changes realizes monitoring in real time, and equipment is intelligent more.
Description of drawings
Accompanying drawing is the structural representation of fiber drawing furnace gas flow automatic control device of the present invention.
Embodiment
Fiber drawing furnace gas flow automatic control device mainly is made up of fiber drawing furnace 1, pressure transmitter 2, transmitter 3, PLC controller 4 and master control computer 5 as shown in the figure.When prefabricated rods 6 welding positions enter in the process of fiber drawing furnace 1, because the variation in rod footpath, gas field in the fiber drawing furnace changes, change by pressure transmitter 2 detecting pressure, pass the signal to PLC controller 4 by transmitter 3, the furnace pressure of monitoring reflection in real time changes on master control computer 5, and PLC controller 4 utilization pid algorithms are regulated the MFC gas flow automatically simultaneously, to reach the stable of gas field and thermal field in the fiber drawing furnace, guaranteed the high quality that optical fiber is made.
