For achieving the above object, the utility model provides following technical scheme: a kind of diaphragm type liquid foot cell pellet mill negative pressure sucking-exhausting device, it is characterized in that: include the preservation liquid bottle that can rotate in a circumferential direction, vacuum diaphragm pump, waste liquid bottle, solenoid directional control valve and mould pipe, it is characterized in that: described solenoid directional control valve includes two groups, two groups of solenoid directional control valves are connected with vacuum diaphragm pump respectively, mould pipe is connected with waste liquid bottle by conduit, waste liquid bottle is communicated with one group of solenoid directional control valve wherein, mould pipe is communicated with another group solenoid directional control valve, one side of waste liquid bottle is provided with connected air receiver.
The utility model is further set to: one group of solenoid directional control valve is F1 solenoid directional control valve and F3 solenoid directional control valve; Another group solenoid directional control valve is F2 solenoid directional control valve and F4 solenoid directional control valve; Described F1 solenoid directional control valve and F3 solenoid directional control valve are in parallel with vacuum diaphragm delivery side of pump, and F2 solenoid directional control valve and F4 solenoid directional control valve are in parallel with the input end of vacuum diaphragm pump; Waste liquid bottle is communicated with F2 solenoid directional control valve, and mould pipe is communicated with F1 solenoid directional control valve.
The utility model is further set to: air receiver is provided with pressure transducer.
In sum, in use, mould pipe immerses and is placed with in the preservation liquid bottle of cell liquid, vacuum diaphragm pump work, one group of solenoid directional control valve is opened (F2 solenoid directional control valve and F4 solenoid directional control valve), another group solenoid directional control valve (F1 solenoid directional control valve and F3 solenoid directional control valve) cuts out, vacuum diaphragm pump is by the Bas Discharged in waste liquid bottle and air receiver, make formation negative pressure in waste liquid bottle and air receiver, because mould pipe is communicated with F1 solenoid directional control valve, the connection of F1 solenoid directional control valve is cut off, so now negative pressure forces again liquid injection film pipe in preservation liquid bottle to disappear to negative pressure, reach the function that imbibition is filtered, after mould pipe is adsorbed onto to a certain degree by the cell liquid in preservation liquid bottle, mould pipe takes out by preserving in liquid bottle, now in mould pipe, absorption has cell liquid, and mould pipe is reversed, make the opening upwards of mould pipe, vacuum diaphragm pump is task again, by waste liquid bottle, Bas Discharged in air receiver, make its inner negative pressure that produces, waste liquid bottle, negative pressure in air receiver forces in film pipe liquid backflow to waste liquid bottle, on the filtering membrane at mould pipe top, just build up residual cell liquid, after the cell liquid in mould pipe drains in waste liquid bottle completely, film pipe rises and withstands microslide, F1 solenoid directional control valve and F3 solenoid directional control valve are communicated with, F2 solenoid directional control valve and F4 solenoid directional control valve cut off, vacuum diaphragm pump injects positive air pressure in mould pipe, diagnosis cell on the filtering membrane at top is transferred on microslide.In said process, cell liquid does not pass through vacuum diaphragm pump and solenoid directional control valve all the time, can eliminate the source of solenoid valve and vacuum diaphragm pump generation fault, without frequent maintenance, has improved production efficiency, and has reduced maintenance cost.
Below in conjunction with accompanying drawing, the utility model is further described.
