Embodiment
Below in conjunction with accompanying drawing being described in further detail to embodiment of the present utility model:
As shown in Figure 1, this Portable Automatic anaerobism/little aerobic culture apparatus is made of normal mixture source 1, culture tank 2 and main control system 3, above main control system, be provided with gas source interface 10, gas displacement interface 11 and portable handle 16, the operating panel of main control system is provided with vacuum tightness indicator gauge 8, also have start button switch 14 and functional select switch 15, normal mixture source 1 is connected with gas source interface 10 on the main control system 3 by source of the gas pipe connecting 12, and the gas displacement interface 11 on the main control system 3 is connected to the fast interface of culture tank 2 by quick connecting pipe 13.Main control system 3 is built-in with oilless vacuum pump 4, source of the gas magnetic valve 5, vacuumize magnetic valve 6, pressure transmitter 7, microprocessor control circuit 9 and pipe installation, Fig. 2 has shown the annexation between each parts, normal mixture source 1 is connected to the input interface (through gas source interface 10) of source of the gas magnetic valve 5, oilless vacuum pump 4 is connected with the output interface that vacuumizes magnetic valve 6, the output interface of source of the gas magnetic valve 5 and the input interface that vacuumizes magnetic valve 6 are connected to the fast interface (through gas displacement interface 11) of culture tank 2, pressure transmitter 7 is installed in the gas circuit that inserts culture tank 2, vacuum tightness indicator gauge 8 is connected with pressure transmitter 7, microprocessor control circuit 9 produces source of the gas magnetic valve 5 according to the pressure signal of pressure transmitter 7 inputs, vacuumize the program control signal of magnetic valve 6 and oilless vacuum pump 4, the gas pump drainage and the displacement of control culture tank 2.
