Abstract
The utility model relates to an electrode mercury drop controlling device used in a polarographic chemical analyzer, comprising a shell. A vibrating support is arranged on the shell; a mercury cup is arranged on the vibrating support; the lower end of the mercury cup is provided with a capillary tube, and the upper end is provided with a cup lid; a tension electromagnet is arranged on the cup lid; an extension bar penetrates through the tension electromagnet, the cup lid and the axis of the mercury cup and is enclosed; the upper end of the extension bar is connected with the electromagnet core; the tension electromagnet is internally provided with a compression spring; the lower end of the extension bar is enclosed with the flow passage opening of the capillary tube; the shell is provided with a vibrating electromagnet; and the electromagnet core of the electromagnet is hung on the vibrating support. All the assemblies are combined in a module, vibration is generated in the module, and air bubbles are eliminated, and the resonance defect is overcome, so that the electrode mercury drops can be generated at the same time and have same volumes, and the separation time of the mercury drops can be controlled.
Description
(1) technical field
The utility model relates to a kind of static dropping-mercury electrode of polarogram chemical analysis apparatus, is the improvement to kind electrode, and particularly a kind of electrode mercury drips control device.
(2) background technology
The mercury of mercury electrode drips the size unanimity, Drain time is controlled is that polarogram chemical analysis apparatus electrode detection result guarantees accurately substantially.Now the static dropping-mercury electrode of polarogram chemical analysis apparatus exists bubble to cut off the mercury runner, cause that flow control is inaccurate, mercury drip not of uniform sizely cause, mercury drips defectives such as disengaging time is out of control.Its main cause is that the proportion of mercury is bigger than air, produces negative pressure during the magnet adhesive and brings the air block capillary flow path into.The main cause that continuous shaking appears in the bump external force that separating hydrargyrum drips is to produce resonance, and uncontrollable mercury drips the time interval of disengaging.Mercury occurs and drip defectives such as out of control, that noise is big, cause prohibited data detection true.
(3) summary of the invention
The utility model is in order to remedy the deficiencies in the prior art, provide a kind of electrode mercury to drip control device, adopt straight stifled runner control, electric and magnetic oscillation separating hydrargyrum to drip technology, flow control and vibration control are combined into one, eliminated bubble and resonant defect, made mercury drip the rise time unanimity, mercury drop volume size is consistent, it is controlled that mercury drips disengaging time, realized structural module.
The utility model is achieved by the following technical solution:
Electrode mercury of the present utility model drips control device, and its special character is: it has housing;
Vibration rack is installed in the housing, the mercury cup is installed on vibration rack, kapillary is installed in mercury cup lower end, bowl cover is installed in mercury cup upper end, and the pulling force electromagnet is installed on the bowl cover, and stage clip is installed in the magnetic core upper end of pulling force electromagnet, the lower end of the magnetic core of pulling force electromagnet is connected with the upper end of extension rod, extension rod runs through the center and the sealing of bowl cover, mercury cup, and the lower end of extension rod is corresponding with kapillary upper end runner mouth, and these constitute the structure division of straight stifled runner control;
The vibration electromagnet also is installed in the housing, and the magnetic core of vibration electromagnet is mounted on the vibration rack, and housing is installed crash roll with outside composition surface, and these constitute the structure division of electric and magnetic oscillation separating controlling.
Principle of work: directly stifled runner control is finished by pulling force magnet control extension rod shutoff capillary flow road junction, has significantly reduced space and has improved shutoff speed, has eliminated the bubble interference, can repeat to form the standard mercury of testing usefulness and drip.Vibration control is mounted in that the vibration electromagnetic actuation of enclosure interior finishes, and does not produce resonance, reaches the requirement that mercury of vibration first separation drips.
The beneficial effects of the utility model are, have eliminated bubble and resonant defect, make mercury drip the rise time unanimity, and mercury drop volume size is consistent, and it is controlled that mercury drips disengaging time, reach the requirement that mercury of vibration first separation drips.

Among the figure, 1 housing, 2 vibration racks, 3 mercury cups, 4 vibration electromagnet, 5 kapillaries, 6 extension rods, 7 bowl covers, 8 pulling force electromagnet, 9 stage clips, 10 crash rolls.
(5) embodiment
Accompanying drawing is a kind of specific embodiment of the present utility model.
Electrode mercury of the present utility model drips control device, and it has housing 1.Vibration rack 2 is installed in the housing 1, mercury cup 3 is installed on the vibration rack 2, kapillary 5 is installed in mercury cup 3 lower ends, bowl cover 7 is installed in mercury cup 3 upper ends, pulling force electromagnet 8 is installed on the bowl cover 7, stage clip 9 is installed in the magnetic core upper end of pulling force electromagnet 8, the lower end of the magnetic core of pulling force electromagnet 8 is connected with the upper end of extension rod 6, extension rod 6 penetrates the axle center and the sealing of pulling force electromagnet 8, bowl cover 7, mercury cup 3, extension rod 6 lower ends are corresponding with kapillary 5 upper end runner mouths, and combinations thereof realizes the structure division of straight stifled runner control.Vibration electromagnet 4 also is installed in the housing 1, and the magnetic core of vibration electromagnet 4 is mounted on the vibration rack 2, pastes crash roll 10 on housing 1 and the combined outside face, and combinations thereof realizes the structure division of electric and magnetic oscillation separating controlling.
The course of work of the present utility model is: pulling force electromagnet 8 is according to the rapid pull-up extension rod 6 of instruction, open the capillary flow road junction, mercury solution in the mercury cup 3 flows into the capacity of a mercury of kapillary in the given time, electromagnet 8 discharges then, stage clip 9 promotes the runner mouth that extension rod 6 moves down sealing kapillary 5, the blocking-up air flows into the cavity of mercury cup 3, and the mercury drop volume accurately and has fully suppressed the bubble generation.Vibration electromagnet 4 acts between housing 1 and the vibration rack 2, and vibration produces in enclosure interior, and housing is connected vibration isolation with outside, has suppressed resonance effectively, can accurately vibrate to make mercury drip separation.Realized mercury drip separate controlled.
