Utility model content
The utility model provides a kind of easy to use, measures B B-complex melting point detector accurately.
The technical solution of the utility model is:
B B-complex melting point detector, it is characterized in that, comprise the hollow pair glass pipe that one end open one end is closed, glass tube openend is provided with sealing-plug, sealing-plug is provided with melting point tube, foam is provided with bottom melting point tube, heat transfer medium is filled with in glass tube, electrical heating wire is provided with in heat transfer medium, the temperature controller that electrical heating wire connects, glass tube top is provided with temperature sensor, and temperature controller, temperature sensor are connected with PLC respectively, glass tube inwall is provided with viewport, is positioned at the bottom of melting point tube bottom viewport.Analyzer adopts electric-heating-wire-heating, and have firing rate fast, homogeneous heating, holds manageable advantage;
Analyzer also comprises display screen, memory storage, printing equipment, heating wire is by temperature controller gauge tap, temperature controller, temperature sensor are controlled by PLC, temperature to the temperature of the heat transfer medium when solid melts that temperature sensor is collected, and is stored in memory storage by PLC, and is outputting to display and printout on display screen, printing equipment;
Hollow pair glass pipe can insulation; Be provided with foam bottom melting point tube, foam can increase the heating surface of solid matter in melting point tube, and increase the speed of melting, foam structure conveniently can also observe the thawing degree of solid, improve the accuracy of measurement; The preferred material of heat transfer medium is silicone oil.
Wherein, foam is spherical, is flat bottom foam.Foam is spherical, can increase heating surface area, is flat bottom foam, can conveniently observe the thawing degree of solid.
Wherein, viewport is outside narrow, and inner wide is tubaeform.Improve observing effect, and another effect of viewport can be used for the measurement to heat-transfer medium temperature by laying temperature sensor in viewport.
