Abstract
The utility model experiment anaerobic ferment devices, including thermostatic water bath, anaerobic fermentation bottle, gas washing bottle, graduated cylinder, sink；Anaerobic fermentation bottle is placed in thermostatic water bath；Anaerobic fermentation bottle is connected with gas washing bottle by conduit；Gas washing bottle is connected to graduated cylinder by gas-guide tube；Graduated cylinder is placed in sink.The utility model can save a large amount of anaerobic fermentation experimental costs, and have good air-tightness, and scientific production air-flow journey, the large quantity of exhaust gas of generation is absorbed with wash bottle, reduce experimental error, and experimental data is reliably true.
Description
Technical field
The utility model relates to a kind of anaerobic ferment devices more particularly to a kind of experimental teaching anaerobic ferment devices.
Background technique
The problems such as common anaerobic ferment devices majority volume in laboratory is big, and device connection is complicated, is easy gas leakage.City at present
The purchase of anaerobic fermentation sets on field, universal higher price, and it is complicated for operation, it is unfavorable for teaching Process of experiment middle school student
Study use.In general laboratory, anaerobic ferment devices are more simple and crude, and air-tightness and gas collection rate are poor, to experiment
Normal operation and experimental data accuracy generate large effect.If carrying out experimental teaching, operating cost is high, and student is not
It is easy to operate.
Utility model content
Based on the above issues, the utility model provides a kind of experiment anaerobic ferment devices, builds simply, small in size,
Operating cost is cheap, and it is convenient to operate, and is conducive to student and learns to inspire；And the covering device has strict air-tightness, the first of generation
Alkane and large quantity of exhaust gas can be collected into purer methane by gas washing in drexel bottle, reduce experimental error, and test number
Really it is suitable for laboratory batch anaerobic fermentation according to reliable and tests, convenient for promotes.
Technical solution is as follows：
The utility model experiment anaerobic ferment devices, including thermostatic water bath, anaerobic fermentation bottle, gas washing bottle, graduated cylinder, water
Slot；Anaerobic fermentation bottle is placed in thermostatic water bath；Anaerobic fermentation bottle is connected with gas washing bottle by conduit；Gas washing bottle passes through
Gas-guide tube is connected to graduated cylinder；Graduated cylinder is placed in sink；Anaerobic fermentation bottle is ground conical flask, and ground conical flask one side wall is equipped with
Sample tap, ground conical flask are furnished with ground bottle stopper, and ground bottle stopper is hollow glass plug, and upper end is equipped with gas outlet；Gas washing bottle master
Body is conical flask, and conical flask one side wall is equipped with gas outlet, and gas-guide tube is housed on gas outlet, is furnished with rubber stopper, rubber on conical flask
Rubber plug is hollow, placement spherical hollow plug in conical flask, is hollow sphere in the middle part of spherical hollow plug, spherical hollow holds be equipped with beyond the Great Wall
Upper conduit, spherical hollow plug lower end are equipped with downcomer, the center of circle of the center line of upper conduit, the center line of downcomer and hollow sphere
In a straight line；The upper conduit of spherical hollow plug passes through rubber stopper hollow part, connect with the gas outlet of ground bottle stopper.
Spherical hollow plug diameter is less than the bottleneck diameter of conical flask.
The downcomer of spherical hollow plug and the conical flask distance from bottom are 10cm -30cm.
The utility model experimental teaching anaerobic ferment devices are a set of with anaerobic fermentation bottle, gas washing bottle, gas receipts
Acquisition means are connected, and fermentation flask is placed in thermostatic water bath, and for controlling fermentation temperature, thief hatch rubber tube and tongs are close
It closes, while end opening is connected with gas washing bottle for absorbing the exhaust gas produced in gas port grinding bottle beyond the Great Wall；It is spherical empty in gas washing bottle
Heart plug is fixed in conical flask by rubber stopper, spherical hollow plug, can inventory of gas, work as a buffer；Gas collector is
Inverted graduated cylinder is placed in sink, collects gas using draining water gathering of gas law.The utility model can in the case where every average daily sampling,
The strict airtightness of a whole set of experimental provision is controlled, and makes to generate a large amount of gas and be absorbed with wash bottle, is not in suck-back phenomenon,
Reduce experimental error.As anaerobic fermentation substrate can be sampled by thief hatch, while the gas generated, by upper conduit, by ball
Shape hollow plug mutually hits with conical flask using downcomer, gas is distributed in the absorbing liquid in taper, increase gas with
Absorbing liquid contact area in conical flask accelerates reacting for gas and absorbing liquid, prevents the generation of suck-back phenomenon, be not absorbed
The final gas that liquid absorbs has obtained final required gas by the outlet of conical flask side.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model experiment anaerobic ferment devices.
