Reached completely the utility model discloses a can swift, convenient, the quantitative invention mesh of transferring to liquid from a container another container and low price.
Description
Technical field
This utility model relates to a kind of experimental provision, particularly relates to a kind of use for laboratory Pneumatic type liquid transfer device.
Background technology
It is known that school is equipped with laboratory to meet teaching needs, laboratory needs for student experimenting, it is necessary to stocking some liquid, in these liquid, some is poisonous or corrosivity is stronger.It will be extracted a certain amount of liquid in experiment container from former reservoir by these liquid when testing, if all manual operationss, exists for the biggest potential safety hazard.Typically now use has following several liquid transfer device.
1, negative-pressure type liquid material transfer device: the transfer device of this liquid material is the transfer device of liquid material under a kind of condition of negative pressure, its structure is mainly: be provided with high level switch and low liquid-level switch on negative-pressure liquid-storing groove, the discharging opening of negative-pressure liquid-storing trench bottom is connected with the import of liquid chiller, the outlet of liquid chiller is connected with the import of infusion pump again, transfusion delivery side of pump is connected with the import of receiving slit after being connected with check-valves again, the high level switch of negative-pressure liquid-storing groove is connected with the control switch of infusion pump with low liquid-level switch, the switch that controls of infusion pump is connected with the motor of infusion pump.Use above-mentioned transfer device, easily liquid can be transferred out under conditions of negative pressure.
The defect of negative-pressure type liquid transfer device be the liquid material typically newly entered be all to seal, the container bottom containing liquid also will not be designed with discharging opening switch.Even if there being discharging opening to switch, the most not necessarily the import with your infusion pump matches.Limitation is big the most in actual applications.
2, siphon liquid transfer device: siphonage is that between liquid molecule, gravitation is poor with potential energy to be caused, i.e. utilize head of liquid poor, liquid is made to then flow into lower after rising. owing to mouth of pipe liquid level bears different atmospheric pressures, liquid can by pressure big flow to pressure little while, equal to the atmospheric pressure on both sides, liquid level in container becomes identical height, and liquid will stop flowing.Liquid in container can be extracted out soon hence with siphonage.
The defect of siphon liquid transfer device is first should in liquid guiding tube to fill this liquid in operation, then be respectively put in two containers by two openings of liquid guiding tube, and liquid inlet is higher than liquid outlet, could realize the transfer of liquid.Moreover most liquid is the most poisonous, be there is potential safety hazard in operator.Liquid in container all can not be shifted.
Utilize water pump transfer liquid: water pump, refer to possess (water) mouth of bleeding of one-in-and-one-out, each one of exhaust nozzle (water), and can persistently form vacuum or negative pressure in import department；Pressure-fired is formed at exhaust nozzle；Working media can be gas, it is possible to for liquid, a kind of instrument of compact.Bottle with liquid-out can be considered and connect the level height of liquid bottle.Operational approach is: first fills liquid in entering fluid catheter, places in the container of holding liquid, also should ensure that the liquid in fluid catheter does not flows out before starting motor, could realize liquid transfer after motor starting.
The defect of water pump liquid transfer device is first to fill liquid in entering fluid catheter in operation, places in the container of holding liquid.Be there is potential safety hazard in operator, the most virose liquid.Long-time electro-motor is used the most easily to be corroded damage.Follow-up maintenance cost is higher.
4, piston-type water pump transfer liquid: inserted in a liquid by the feed tube of piston-type water pump, when mentioning piston, atmospheric pressure makes liquid push open in valve entrance cylinder；During pressure piston, piston liquid below is pressed on valve and makes valve closing, and liquid then enters upper piston area by the gap of piston with stack shell.So by the up and down motion of piston, the keying of valve and the varicose of rubber piston, constantly the liquid in container is pumped endlessly, and make liquid flow out from drain pipe.
The defect of piston-type water pump transfer liquid is to have a little liquid to splash out from the upper end of piston the most unavoidably, damages operator.The connecting rod of general piston is all that metal is easily damaged by some liquid corrosion, causes using.
Utility model content
The purpose of this utility model be to provide to overcome the deficiencies in the prior art a kind of energy quick and easy, quantitative liquid is transferred to another container and low-cost use for laboratory Pneumatic type liquid transfer device from a container.Its concrete technical scheme is: use for laboratory Pneumatic type liquid transfer device includes Liquid storage container, transfer vessel, with switch and the air pump of speed governing button, enter fluid catheter, eluate conduit, high-pressure air pipe, the charging aperture of Liquid storage container is provided with a seal disc, a rubber gasket is had between seal disc and discharging opening, seal disc is connected with charging aperture by several fixing buckles with rubber gasket, one air inlet pipe one end is tightly embedded in the air inlet of seal disc and rubber gasket, the other end is connected with the gas outlet of air pump by high-pressure air pipe, enter fluid catheter one end be tightly embedded in seal disc and the liquid outlet of rubber gasket and stretch in liquid, the other end is connected with eluate conduit.
When using this utility model use for laboratory Pneumatic type liquid transfer device, first seal disc is connected with charging aperture by several fixing buckles with rubber gasket, make it the most airtight, again air inlet pipe is tightly embedded in the air inlet of seal disc and rubber gasket, tightly it is embedded in seal disc and the liquid outlet of rubber gasket by entering fluid catheter and stretches in liquid, the port of export of eluate conduit is put in transfer vessel, and starting air pump just can be with transfer liquid.If desired for the transfer velocity of control liquid, can be realized by the speed governing button on regulation air pump.This device can be additionally used in the liquid transfer of hospital and factory.
Can be seen that from the technical solution of the utility model, owing to structure is relatively simple reliably, completely avoid the problem existing for prior art, reached energy of the present utility model quick and easy, quantitative liquid is transferred to another container and low-cost goal of the invention from a container.
