Secondary meter is delivered in detection, change, controls feed system.Because of unstable, bigger, the shakiness of charging of feed system fluctuation of detection
It is fixed to feed back to liquid level again, whole system is not stablized.The purpose automatically controlled is can not be completed, labor intensity of operating staff increases
Add, and add destabilizing factor.
The content of the invention
The utility model aims to solve the problem that drawbacks described above, there is provided a kind of continuous bubbling of online liquid level gauge stable output signal
Liquid level gauge on-line measurement voltage-stabilizing system.
In order to overcome defect present in background technology, the utility model solves technical scheme used by its technical problem
It is：A kind of bubble liquid level meter on-line measurement voltage-stabilizing system, including polymerization reaction kettle, the polymerization reaction kettle is interior to be provided with agitator,
The polymerization reaction kettle is sequentially connected bubble liquid level instrumentation device and secondary meter liquid level PID control device, the polymerization
Measurement stable-pressure device is additionally provided between reactor and bubble liquid level instrumentation device, the polymerization reaction kettle is also sequentially connected bubbling
Air blowing adjusting means and bubbling air blowing source of the gas, the measurement stable-pressure device include connected measurement voltage regulation adjustor and measurement voltage stabilizing
Surge chamber, measurement voltage stabilizing surge chamber play buffering pressure stabilization function.
In a preferred embodiment of the present utility model, measurement voltage regulation adjustor is pneumatic regulating valve of damming, for adjusting
Gas pressure of the section into surge chamber.
The beneficial effects of the utility model are：Present apparatus small investment, online liquid level gauge stable output signal is continuous after installation,
Therefore, feeding control system continuous-stable, reduce the loss of equipment, feed system is adjusted without the change with liquid level
Parameter, and simple and fast is debugged, effect stability is reliable；The automaticity of production control is improved, for stable prod matter
Amount plays an important role；Reduce the working strength of operating personnel.
Brief description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples.
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the structural representation of the utility model measurement stable-pressure device.
Embodiment
Preferred embodiment of the present utility model is described in detail below in conjunction with the accompanying drawings, so that the advantages of the utility model
It can be easier to be readily appreciated by one skilled in the art with feature, it is apparent clear and definite so as to be made to the scope of protection of the utility model
Define.
A kind of bubble liquid level meter on-line measurement voltage-stabilizing system as shown in Figure 1, including polymerization reaction kettle 1,1 in polymerization reaction kettle
Provided with agitator 2, polymerization reaction kettle 1 is sequentially connected bubble liquid level instrumentation device 3 and secondary meter liquid level PID control device
4, measurement stable-pressure device 5 is additionally provided between polymerization reaction kettle 1 and bubble liquid level instrumentation device 3, polymerization reaction kettle 1 also connects successively
Bubbling air blowing adjusting means 6 and bubbling air blowing source of the gas 7 are connect, it is steady that the measurement stable-pressure device 5 includes connected measurement as shown in Figure 2
Adjuster 51 and measurement voltage stabilizing surge chamber 52 are pressed, polymerization reaction kettle 1 is sequentially connected measurement voltage regulation adjustor 51, measurement voltage stabilizing buffering
Room 52 and bubble liquid level instrumentation device 3；Measurement voltage regulation adjustor 51 is pneumatic regulating valve of damming.
By adding measurement stable-pressure device between polymerization reaction kettle and bubble liquid level instrumentation device so that polymerization is anti-
Fluctuation and agitation characteristics of the kettle because of vacuum system are answered, the measured voltage regulation adjustor of fluctuation and measurement voltage stabilizing for producing melt level delay
Rushing room, effectively buffering is fallen so that feed system fluctuation is small, improves the stabilization of detection, realizes the purpose automatically controlled.
Embodiment of the present utility model is the foregoing is only, not thereby limits the scope of the claims of the present utility model, it is every
The equivalent structure or equivalent flow conversion made using the utility model specification and accompanying drawing content, or be directly or indirectly used in
Other related technical areas, similarly it is included in scope of patent protection of the present utility model.
