A kind of film filter
Technical field
The utility model relates to a kind of experimental provision, relates in particular to a kind of film filter.
Background technology
At present, membrane separation technique, can be by solution purification, separates or concentrates.Micro-filtration and hyperfiltration technique are mainly used in holding back the macromolecular substances such as suspension, colloid, particulate, bacterium and the virus in removal solution.Conventional film filter has restive flow velocity, noise is large, volume is large, the shortcoming such as large takes up room.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of film filter simple in structure, easy and simple to handle.
For addressing the above problem, a kind of film filter described in the utility model, is characterized in that: this device comprises peristaltic pump and filtering membrane tube; Described peristaltic pump is provided with peristaltic pump tube, and the entrance point I of this peristaltic pump tube is placed in liquid storage container, and its port of export is connected with the entrance point II of described filtering membrane tube; On described filtering membrane tube, be respectively equipped with the filtered fluid port of export, concentrated solution outlet end; The described filtered fluid port of export is connected with collection container; Described concentrated solution outlet termination enters in described liquid storage container; Described concentrated solution outlet end is connected with bayonet socket tubule I, and is provided with a bead I with holes; The entrance point of described peristaltic pump tube is connected with bayonet socket tubule II, and is provided with a bead II with holes.
Described filtering membrane tube is inner pressed or external-compression type micro-filtration membrane pipe or ultrafiltration membrane pipe.
The diameter of described bead I with holes and described bead II with holes is 0.5 ~ 2cm.
The utility model compared with prior art has the following advantages:
1, because the utility model adopts peristaltic pump sample introduction, filtering membrane tube is carried out to cleaning and regeneration process, simple with conventional film filter structure compared, in filter process, flow process is short, easy and simple to handle and noise is little, is easy to control and safeguard; The utility model controllable flow speed simultaneously.
2, the utility model carries out at normal temperatures, and mild condition is destroyed without composition, thereby suitable to especially heat sensitive material, as the separation of medicine, enzyme, fruit juice etc., classification, concentrated and enrichment.
3, owing to being provided with peristaltic pump and filtering membrane tube in the utility model, therefore, the utility model separative efficiency is high, and to the filtration of suspension in solution and particle, concentrating of low concentration solution is all very effective.And need not heat in experimentation, energy consumption is low, without adding chemical reagent, pollution-free, energy-conserving and environment-protective.
4, the utility model is simple in structure, can be applied to the fields such as food, beverage processing, medical industry, biologic product and Chinese medicine preparation.
