The use method of the multifunctional biological experiment table comprises the following steps:
step one, stirring materials and conveying the materials:
the plug cap is unscrewed, liquid raw materials are added into the crucible, the motor V and the heating wire are started through the control device, the liquid raw materials are heated and stirred, the exhaust valve II is opened after stirring is completed, inert gas in the gas cylinder II enters the gas passage through the inert gas exhaust pipe and enters the inner cavity of the crucible through the exhaust hole, the pressure of the inner cavity of the crucible is improved, the liquid level of the raw materials is extruded downwards, the liquid raw materials are discharged upwards through the feeding pipe and enter the inner part of the infusion main pipe under the action of the pressure, and then the liquid raw materials are distributed to the corrugated discharge pipe or the oxygen isolation box discharge pipe through the distribution valve;
step two, oxygen removal of the oxygen isolation cabinet:
screwing off an exhaust valve I, discharging nitrogen gas filled in a gas cylinder I into an oxygen separation cabinet through a nitrogen gas exhaust hole, continuously increasing the pressure in the oxygen separation cabinet by high-pressure nitrogen gas, when the gas pressure in the oxygen separation cabinet is greater than the thrust of a spring in a one-way oxygen discharge valve, pushing a sealing plate to move towards a top plate by the gas in the oxygen separation cabinet, opening a gas hole I, entering the gas in the oxygen separation cabinet into a sliding cavity through the gas hole I and discharging the gas into the atmosphere through a gas hole II, and completely replacing the air in the oxygen separation cabinet into the nitrogen gas through the steps to achieve the oxygen removal effect;
step three, the test tube in the oxygen isolation cabinet receives the liquid raw material and the electron microscope I moves:
the electric lifting rod is started by the control device to lift the tray until the upper end opening of the test tube inside the test tube groove is close to the tube mouth of the oxygen box liquid discharging tube. And adjusting the distribution valve to enable the oxygen isolation box liquid discharge pipe to discharge the liquid raw materials into the test tube. After one of them test tube had received liquid raw materials, stopped to separate oxygen case casting pipe release liquid raw materials, starter motor IV drives test tube fixed block I through drive gear IV and rotates, and to another test tube aim at oxygen case casting pipe mouth, then to the inside release liquid raw materials of this test tube. An operator stretches a hand into the telescopic sealing glove, the rotary table is rotated, the rotary table drives the screw I to rotate, and then the slide block in threaded connection with the screw I drives the electron microscope I to move together to reach a position convenient for the operator to operate;
step four, operating the test tube fixing block II and automatically cleaning the test tube:
insert the test tube between half slot and the mounting plate, when four limits of square commentaries on classics piece and push rod summit contact, half slot and mounting plate clearance are greater than the diameter of test tube, and the test tube can freely be taken out, facilitates the use, and when starting the electro-magnet, the valve rod of electro-magnet drives the rack and removes, and then makes square commentaries on classics piece rotate, and four fillets of square commentaries on classics piece contact with the push rod summit respectively, and the mounting plate removes to the half slot direction, with the test tube chucking. Starting motor I drives the rack bar rotation through drive gear I, and then makes the returning face plate drive II upsets 180 of test tube fixed block, and the mouth of pipe of test tube is perpendicular down. Starting motor II, it is rotatory through drive gear II and intermediate wheel drive gear I, and then drive screw rod II and rotate, because screw hole threaded connection on screw rod II and the washing piece, consequently when screw rod II rotates, wash the piece rebound, insert the inside bottom of test tube until the vertical rod in the middle of the support frame, stop motor II, at this moment the vertical rod in the middle of the support frame is located inside the test tube, and the peripheral ring of vertical rod is located the test tube outside. Starting motor III and suction pump, inside the suction pump passes through the hose with the inside water of water tank and pours into main water course into to flow into the inside water cavity of purger through the water diversion channel, then spout the sponge through the hole for water spraying, wet the sponge, conveniently wash the test tube. The motor III drives the gear II to rotate through the driving gear III after starting, so that the support frame rotates, the sponge on the vertical rod in the middle of the support frame cleans the inside of the test tube, and the sponge on the ring on the periphery of the vertical rod cleans the outside of the test tube. The inside water that flows into the washing chamber during washing is most discharged through drain pipe I, and some water can flow downwards along screw rod II in addition, when this part rivers were to the upper surface of gear I, because the rotation of gear I and screw rod II, this part of water can be swung all around under the effect of centrifugal force, hits the fender and circles and flow into the water catch bowl inside downwards through the hole that leaks and the water leakage pipe, at last through the II dischargings of drain pipe.
Compared with the prior art, the invention has the following beneficial effects:
(1) have the oxygen cabinet that separates, conveniently carry out the experiment that needs under the five oxygen environments.
(2) The test tube can self-cleaning, convenient and fast.
(3) The centralized treatment of the waste water is beneficial to preventing and controlling water pollution.
(4) The stirring of the liquid raw materials in the crucible adopts horizontal stirring, and the stirring area is large and more uniform.
