Efficiency, and can not achieve membrane cavity and be isolated well with connecting rod chamber, corrosive gas is likely to scurry into connecting rod chamber
And damage equipment.
Micro-porous filter is the filter membrane by sample by certain pore size, is trapped in microorganism on filter membrane, then trained
It supports, count.This method can be used in the microorganism detection of food, it is also possible in flushing water, injection water, the microorganism point for processing water
Analysis is the generally acknowledged optimum detection method of the U.S., Europe, Japanese Pharmacopoeia.But in existing membrane filtration equipment, due to filter membrane
The vacuum degree that surface is formed when filtering is inconsistent, and the microbial profile being trapped on micro- air filter film is uneven and causes cultivating
It is difficult to estimate micro organism quantity later.Furthermore existing filter membrane filtering system mostly uses greatly the mode fixed funnel of additional fixture,
Also there is few part to be fixed using the mode that screw thread is tightened simultaneously.Both the above connection type is torn open all there is structure is complicated
Fill it is loaded down with trivial details, can not one-handed performance the disadvantages of.

Device and a filter bowl dismantling connection are additionally provided with the adjusting of an independent control on-off and uninterrupted in each attachment device
Valve；Surge tank internal vent position is equipped with an Anti-overflow device, this has an air mistake between surge tank and vacuum pump
Filter；The entrance of the surge tank is unified crossover sub by constant pressure current divider or N and is connected to the attachment device of filter bowl.
Preferably, the entrance of the surge tank is two be arranged side by side, it is separately connected a constant pressure current divider and one
A N unifies crossover sub, and the entrance that constant pressure current divider and N unify crossover sub can be connected to the attachment device of filter bowl.
Preferably, the attachment device bottom end of three filter bowls is respectively an adjustable hose, the other end of hose
For threaded connector, three connectors of constant pressure current divider can be respectively communicated with, or are connected to the entrance of N unification crossover sub entirely.
Preferably, the oilless vacuum pump top is equipped with the vacuum meter of monitoring air pressure, being additionally provided with one prevents air pressure super
The excess pressure valve of limit damage oilless vacuum pump.
Preferably, the bottom end of the reservoir is additionally provided with the tapping valve for facilitating discharge liquid.
Compared with the prior art, the advantages of the utility model are: multiple filter bowls of multi-joint filter work at the same time, increase
The hose of attachment device is just connected to by working efficiency if identical to the rate request of several filter bowls by constant pressure current divider
Surge tank, the device can reduce systematic error caused by pressure loss while measure multi-group data；If to the speed of several filter bowls
Degree is required without same, and the hose of attachment device is just unified crossover sub by N and is connected to surge tank, it is long to reduce transduction pathway
Degree saves energy.
