Description
Technical field
The utility model is related to toxic waste liquid in laboratory and handles relevant apparatus, specifically a kind of laboratory noxious acidic liquid
Body siphoning installation.
Background technology
Microfossil research is the important subject branch of Global climate change and environmental evolution research, with science and technology
Rapid development, the professional research institution of Microfossil experiment has been established in major Research Center in one's power colleges and universities, troop is huge
Greatly, cryptogam experimental analysis is the important method of Microfossil.The volatile strong acid and strong base of tool is usually used in these experiments
The toxic gas generated during liquid reagent, especially hydrofluoric acid experiment process, it is larger to experimental analysis personnel's actual bodily harm,
It is extremely hazardous.
Currently used method is will to test the toxic liquid in draught cupboard directly toward the plastics outside laboratory fume hood
Topple in bucket, since plastic bucket is exposed in Laboratory air, the toxic gas of bung hole volatilization will diffuse into entire experiment
Interior easily causes certain injury to experiment operator, also can corrosion experiment room instrument.
Utility model content
The purpose of this utility model is to provide a kind of laboratory noxious acidic liquid siphon apparatus, to solve to give up in laboratory
Liquid bucket, which is exposed in Laboratory air, causes toxic gas to volatilize and generated to experiment operator health dysgenic
Problem.
What the purpose of this utility model was realized in：
A kind of laboratory noxious acidic liquid siphon apparatus, includes waste liquid barrel, and exhaust is provided in the waste liquid barrel
Mouth, inlet, leakage fluid dram and feeding port；The exhaust ports are plugged with exhaust pipe, inside the other end and draught cupboard of exhaust pipe
Connection；Siphon pipe is plugged at the inlet, the outlet side of siphon pipe stretches into the waste liquid barrel, and the suction side of siphon pipe is stretched
Enter in the experiment beaker in draught cupboard；It is provided with valve switch at the leakage fluid dram；It is provided with closing cap at the feeding port.
Toxic liquid is drawn into device by the device of the utility model by rubber hose, using gas circulation principle,
Toxic gas is discharged in draught cupboard, toxic gas is avoided and is dispersed into laboratory, the object for neutralizing soda acid has also been devised in device
Product have also carried out attenuation treatment to toxic liquid, have not only remained original experimental method, but solve experiment in generate it is toxic
Injury of the acidic liquid to human body, siphon circulation design solve injury of the toxic gas to experimenter's body, ensure that section
Grind the safety of personnel.The utility model is tried out in having tested, and is worked well, easily operated, in major scientific research institution and colleges and universities' subject
Application prospect is fabulous in experiment.
Description of the drawings
Fig. 1 is the utility model overall structure diagram.
In figure：1, draught cupboard, 2, waste liquid barrel, 3, exhaust pipe, 4, siphon pipe, 5, feeding port, 6, leakage fluid dram, 7, experiment burns
Cup.
Specific implementation mode
As shown in Figure 1, the device of the utility model, is to increase a siphon circulation knot on the basis of existing draught cupboard
Structure includes mainly a waste liquid barrel 2, exhaust outlet, inlet, leakage fluid dram 6 and feeding port 5, feeding port is provided in waste liquid barrel 2
Closing cap is provided at 5.Exhaust outlet 2 is set to the roof of waste liquid barrel 2, and exhaust pipe 3, exhaust pipe 3 are plugged with everywhere in exhaust outlet 2
The other end and the inside of draught cupboard 1 be connected to.Siphon pipe 4 is plugged at inlet, the outlet side of siphon pipe 4 stretches into waste liquid barrel 2,
The suction side of siphon pipe 4 is stretched into the experiment beaker 7 in draught cupboard 1.It is provided with valve switch at leakage fluid dram 6.In addition, new at this
The handle conveniently guided and supported can be also set in the waste liquid barrel 2 of type.
When toxic volatile liquid in draught cupboard 1 in beaker needs discarded, venom has been stretched into the suction side of siphon pipe 4
In vivo, it is drawn in waste liquid barrel by siphonage, the reagent for neutralizing toxic liquid is then launched by feeding port 5, with drop
The toxicity of low toxic liquid, the toxic liquid to be volatilized during this are discharged by exhaust pipe 3 in draught cupboard 1, avoid polluting
Room air.
For the waste liquid in waste liquid barrel 2, siphon pipe 4 and exhaust pipe 3 are extracted from inlet and exhaust outlet first, then will be given up
Liquid bucket 2 is put to draught cupboard 1, is then opened the valve at leakage fluid dram 6, is carried out safety dumping.
