Fig. 2 is the A-A direction view of Fig. 1.
In figure: 1, outer cylinder；2, inner cylinder；3, bracket；4, filter membrane；5, interior convex edge；6, sealing cover.
Specific embodiment
As shown in Figure 1 and Figure 2, the utility model includes outer cylinder 1, inner cylinder 2, filter membrane 4, bracket 3 and sealing cover 6.Inner cylinder 2
Inner cylinder 2 and outer cylinder 1 are connected with each other positioned at the inside of outer cylinder 1, and by bracket 3, make to be formed between outer cylinder 1 and inner cylinder 2 certain
Space be used for storing solution.Several circular holes are provided on the side wall of inner cylinder 2, filter membrane 4 is set at the circular hole on inner cylinder 2, and
Filter membrane 4 covers circular hole completely, and the solution of inner cylinder 2 is entered after the filtering of filter membrane 4 in outer cylinder 1.
Bracket 3 exists only in the top half of device, and inner cylinder 2 can be supported in outer cylinder 1, make inner cylinder 2 in outer
Cylinder 1 does not occur directly to contact.The number of bracket 3 should be no less than two, and be uniformly distributed around the axis of outer cylinder 1, and inner cylinder 2 is fixed
On bracket 3, the axis of inner cylinder 2 is overlapped with the axis of outer cylinder 1.Wherein bracket 3 is specifically four, and is in cross distribution.
It is also provided with through-hole on bracket 3, so that the solution when being centrifuged and toppling between outer cylinder 1 and inner cylinder 2 is in flowing
Too big resistance is not will receive.
Several filter membranes 4 are installed on 2 side wall of inner cylinder, the minimum range at minimum filter membrane 4 and 2 bottoms of inner cylinder is inner cylinder 2
Cylinder is high by 2/3, and solid is located at the bottom of inner cylinder 2, and when vibrating, fraction solids particle is dispersed in liquid, but due to its quality compared with
It will not be suspended into higher position greatly, so that will not pollute filter membrane 4 influences the function of filter membrane 4.Having for solution is dissolved in centrifugation
Machine matter passes through filter membrane 4 under the action of the centrifugal and enters outer cylinder 1, realizes the filtering to solution, obtains organic matter solution.
Convex edge 5 in a circle or multi-turn is additionally provided on the inner wall of inner cylinder 2, interior convex edge 5 is located at the interposition of 2 height of inner cylinder
It sets, in centrifugation, solid particle can be stopped by interior convex edge 5, not will be shifted up to the top of liquid, to make particle aggregation in convex
Along 5 positions below, it ensure that the efficiency of filtering and keep the function of filter membrane 4 unaffected.
Need to also there be one section on the port cap top cover labyrinth 6 of inner cylinder 2, sealing cover 6 after soil and solution are poured into inner cylinder 2
Cylindrical interior convex edge 5, the diameter of the cylinder are slightly larger than the inner diameter of inner cylinder 2, can be by 2 port sealing of inner cylinder.Lid
After top cover labyrinth 6, in centrifugation and pouring soln, the solution of inner cylinder 2 all cannot directly enter outer cylinder 1 or be dumped away,
The solution of inner cylinder 2 only just can enter outer cylinder 1 through filter membrane 4 and device is poured out by outer cylinder 1, can effectively avoid being obtained by filtration
Organic matter solution polluted by non-filtering solution.
Inner cylinder 2 and outer cylinder 1 are all the recessed U-shaped tube in bottom, and the particle in solution can precipitate downwards and be gathered in bottom.
Wherein filter membrane 4 uses hydrophilic polyethersulfone (PES) filter membrane, and inner cylinder 2, outer cylinder 1 and bracket 3 use polytetrafluoroethylene (PTFE)
Material.
