The technical problem to be solved by the utility model is to provide a kind of multiple samples may be implemented while filtering half certainly
Dynamic continuous filter unit.
The utility model is to solve above-mentioned technical problem by the following technical programs: a kind of semi-automatic continuous filtering dress
It sets, including vacuum tank (1), vacuum container cover (2), vacuum pump (5)；The vacuum container cover (2) is sealed in the vacuum and holds
The opening of device (1), the vacuum pump (5) connect the vacuum tank (1)；Several receptions are equipped in the vacuum tank (1)
The outside of bottle, the vacuum tank (1) is equipped with several sampling bottles；Several funnels are connected on the vacuum container cover (2), it is each to leak
Bucket is respectively communicated in the vacuum tank (1)；The entrance of each funnel connects a corresponding sampling by connecting tube respectively
Bottle, micropump is respectively equipped in each connecting tube；The outlet of each funnel is respectively communicated with into a corresponding receiving bottle, each funnel
Filter mechanism is equipped between corresponding receiving bottle.
As the technical solution of optimization, the funnel uses cylinder scale funnel.
As the technical solution of optimization, the bottom of the funnel is connected through a screw thread the vacuum container cover (2).It can incite somebody to action
Filter membrane is located at threaded connection place, is screwed by screw thread.
As the technical solution of optimization, the outlet of the funnel is communicated in the receiving bottle by conduit.
As the technical solution of optimization, the filter mechanism uses micropore filtering film.
As the technical solution of optimization, flow control valve is further respectively had in each connecting tube.
As the technical solution of optimization, control valve (12) are also connected on the vacuum tank (1).
Utility model has the advantages that multiple samples may be implemented while filtering, filters and clean alternately, save
Manpower and material resources, improve work efficiency, while avoiding sample room cross contamination, reduce experimental error.
