Description
Technical field
The utility model belongs to petrochemical technology field, is specifically related to a kind of polyolefin bunker electrostatic monitor of carrying polyolefin medium process medium carried charge (static) to detect for chemical pipeline.
Background technology
In petrochemical enterprise polyolefin media processes place, due to reasons such as rubbing, peel off, medium tends to carry a large amount of static, is to bring out unique incendiary source that polyolefin bunker fires with dielectric static discharge.Therefore in polyolefin medium production run, particularly carry polyolefin medium to enter in feed bin process at air, accurately grasp dielectric charge situation very important.Polyolefin bunker dielectric charge situation can be tested by stockpile surface voltage, but it is very large to measure difficulty at Workplace, and measuring sonde also may bring out high-energy discharge, causes static to fire.Detecting the entrained quantity of electric charge of unit mass polyolefin medium so constant volume Faraday cylinder is set on material conveying pipeline, is unique feasible program.The disclosed product of existing market, its shortcoming is, the one, it is too many that Faraday cylinder stretches into pipeline, if there is caking medium to pass through, may stop up Faraday cylinder, the equipment that affects normally moves, meanwhile, dwindle device pipeline contact area because Faraday cylinder protrudes, increased resistance to blast system; The 2nd, Transmitter Line plate is arranged in monitor convex structure, too near apart from feeding pipe, is absolutely unsafe, and cannot accomplishes Principle And Method of Flame Retardation Design in convex inside configuration narrow space, is unfavorable for enterprise safety operation.
Utility model content
The purpose of this utility model is to provide one to be fixedly installed in wind and send end in polyolefin particles medium conveying pipeline, simple in structure, operation and maintenance convenient, do not change former pipe section amasss, uses safe polyolefin bunker electrostatic monitor.
Polyolefin bunker electrostatic monitor of the present utility model, on housing, to have connected short circuit, short circuit outlet has connected sealing baffle, in short circuit, fix Faraday cylinder, described Faraday cylinder comprises urceolus, inner core and insulating cylinder, insulating cylinder is placed between urceolus and inner core, Faraday cylinder bottom is provided with removable bottom, removable bottom is fixed on urceolus bottom by rotation axis, rotation axis connects driving cylinder or other driving control devices, described inner core connects signal extension line by M5 bolt, signal extension line passes through sealing adaptor through the sidewall of short circuit, metal short circuit connects the wiring board in the measuring-signal transmitter outside housing, Faraday cylinder sampled signal adopts control cables to be connected with external charge display device by sealing adaptor after the wiring board in measuring-signal transmitter amplifies conversion.
As further improvement of the utility model, measuring-signal transmitter shell is anti-explosion box body, establishes wiring board in casing.
As further improvement of the utility model, described measuring-signal transmitter, comprise explosion-proof type metal shell and the wiring board with amplification and function switching signal, wiring board input signal is connected and fixed the M5 bolt of inner core by extension line, output signal adopts control cables to be connected with external charge display device by sealing adaptor.
The beneficial effects of the utility model are: monitor housing has connected short circuit, and Faraday cylinder is arranged in short circuit, and polyolefin particles block material blocking pipeline linearly, has been avoided in far point and tube wall edge, does not also change the sectional area of pipeline feeding; Measuring-signal Transmitter Line plate is arranged in the outer anti-explosion box body of monitor housing, not only can guarantee equipment electrical safety, is also convenient to safeguard and change.The utlity model has good result of use and the wide prospect of promoting the use of.
