The spring supports downwards the shim (4) arranged at the joint between the middle sleeve pipe and the outer sleeve pipe, and supports upwards the core plug jacket (8), a screw rod (16) and a guide rod (15), and the screw rod (16) and the guide rod (15) are extended into the middle sleeve pipe and mutually sheathed. The outer wall of the top of the middle sleeve pipe is provided with a fixed amplifying path (19), a rotating differential dial (11) with gear teeth (12), and a screwing cover (14). The rotation of the differential dial (11) drives the screw rod (16) to rotate and engage with the screw thread (10) which is fixed on the amplifying path to present an up and down moving state. A pin (21) which is fixed on the differential dial presents an up and down slipping state in the longitudinal slot (20) at the outer wall of the screw rod. The titrator has the advantages of reasonable structure, exact and quick titration, convenient and safe titration, and automatic titration. The utility model is suitable for the titration and reclamation of an azotometer.
Description
Affiliated technical field
The utility model relates to a kind of physico-chemical analysis instrument, and specifically multiple content of material reacts required its result's of judgement autotitrator by analysis.
Background technology
Conventional used buret is by manually being full of intraluminal fluid, the adjustment horizontal line.So-called automatic buret also is to press balloon row and inhale and be full of intraluminal fluid by manually pinching with hand, the horizontal line of harmonizing as a rule, and the breakdown piston, the required liquid of trickling from titrating head is aimed at scale mark by pore size and trickling speed.The component value of conventional 1ml buret is 0.010ml, the component value of 100ml buret is 0.2ml, and analyze requirement is the 3rd figure place behind the radix point, existing buret does not have micro-frame bar directly perceived, wall built-up, residual, hang to drip etc. be the factor that objectively can't get rid of, be the main cause that causes accuracy low, the real difficult control of described half difference, impact analysis precision.
Summary of the invention
It is accurately high that the purpose of this utility model provides a kind of metering, the titrator that titration is automatic, quick, convenient, safe.
In order to achieve the above object, the technical solution of the utility model is: stretching in the scale outer tube has the core plug, be with middle sleeve outside its top and lock by fixed trap, the middle sleeve inner chamber is provided with and is placed in core spring beyond the Great Wall, on the pad that support middle sleeve and outer tube junction are provided with under the spring, upper supporting core plug sheath and the screw rod and the guide rod that stretch in the middle sleeve and be nested, middle sleeve top outer wall is provided with the fixing footpath of amplifying, be with the rotation differential index dial of gear tooth and screw lid, drive the screw rod rotation by the rotation of differential index dial and be motion state up and down with the thread engagement of being fixed on the amplification footpath, the pin that is fixed on the differential index dial is slide down row state in screw rod outer wall cannelure.
The end that described guide rod contacts with core plug sheath is the tapering cap, and the other end is provided with the pressure-lift cap.Be respectively equipped with three fixed point steel balls that make the index dial rotation between the two sides of described differential index dial and tightening cover and amplification footpath, also available ultrathin bearing replaces steel ball.Described scale outer tube outer wall is provided with the standard level scale mark, and screw jacket has protective jacket, and the protective jacket outer wall is provided with the standard level scale mark corresponding with outer tube.Described differential index dial is provided with scale mark, and the differential index dial revolves that to turn around be the horizontal lattice of outer tube scale.The gear matched of described gear tooth and stepper motor is rotated the differential index dial automatically.
This autotitrator measuring accuracy reaches the 3rd figure place behind the radix point, and clear reflecting on buret differential index dial directly perceived, improves 20 times than original buret measuring accuracy; Automatically control titration by stepper motor, eliminate wall built-up, residual, half poor, getting rid of objective and people is the error that causes; Rational in infrastructure, titration is accurate, quick, convenient, safety, realizes laboratory sample titration robotization, more adapts to titration, the recovery of azotometer, and its recovery is reached advanced world standards.
