Abstract
The utility model relates to a detachable type buchner funnel which comprises a mixed material containing part and a liquid filtering part, wherein an internal thread is formed in the bottom end of the mixed material containing part; an external thread and a rubber gasket are arranged at the top end of the liquid filtering part; the mixed material containing part and the liquid filtering part are in seal connection through the threads and the gasket; the mixed material containing part comprises an upper end and a lower end that are fixedly connected; the upper end adopts a first tubular structure with equal diameter at the upper and the lower parts; the lower end adopts a second tubular structure with the diameter gradually reduced from top to bottom; a partitioning is formed between the upper end and the lower end; small holes uniformly distributed are formed in the partitioning. The detachable type buchner funnel provided by the utility model is simple in structure, and as the mixed material containing part and the liquid filtering part are in seal connection through the threads and the gasket, the buchner funnel can be detached down, and is convenient to clean and applicable to large-scale popularization and application.
Description
Technical field
The utility model relates to a kind of detachable Buchner funnel.
Background technology
Common funnel, after sticking filter paper, connects aspiration pump and carries out suction strainer, and because the mouth of common funnel is larger, so negative pressure suction strainer does not have effect.Different from common funnel, Buchner funnel is a kind of ceramic instrument using in laboratory, being used for using vacuum or negative pressure suction to filter is comparatively easily, but, general Buchner funnel is integral structure, clean comparatively trouble, particularly for some stickums, thoroughly clean up hardly and may realize.
Utility model content
Technical problem to be solved in the utility model is: provide a kind of simple in structure, convenient and practical detachable Buchner funnel.
The utility model solves the technical scheme that its technical problem adopts: a kind of detachable Buchner funnel, it is characterized in that: this funnel comprises that mixed material containing part and liquid leach portion, mixed material containing part bottom has internal thread, liquid leaches portion top and has external screw thread and rubber washer, and mixed material containing part and liquid leach portion and realized and being tightly connected by screw thread and packing ring; Described mixed material containing part comprises the top and bottom that are fixedly connected with, upper end is upper and lower isodiametric tubular structure one, lower end is the tubular structure two that from top to bottom diameter reduces gradually, has partition between top and bottom, has the aperture being evenly distributed on partition.
Further, the described liquid portion of leaching comprises upper and lower, and top is the tubular structure four that from top to bottom diameter reduces gradually, and bottom is isodiametric tubular structure five, and tubular structure five lower ends are inclined outlet.
Beneficial effect: compared with prior art; the structure of detachable Buchner funnel of the present utility model is comparatively simple, and mixed material containing part and liquid leach portion by being tightly connected of screw thread and packing ring, and can realize the detachable of Buchner funnel; convenient cleaning, proper scale is applied.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated;
Fig. 1 is mixed material containing part structural representation of the present utility model;
Fig. 2 is that liquid of the present utility model leaches portion's structural representation;
Fig. 3 is the top view of Fig. 1;
In figure, 11. tubular structure one, 12. tubular structures two, 13. cut off, 14. apertures, 21. external screw threads, 22. packing rings, 23. tubular structure four, 24. tubular structures five.
The specific embodiment
A kind of detachable Buchner funnel as shown in drawings, this funnel comprises that mixed material containing part and liquid leach portion, mixed material containing part bottom has internal thread, liquid leaches portion top and has external screw thread 21 and rubber washer 22, and mixed material containing part and liquid leach portion and realized and being tightly connected by screw thread and packing ring 22; Described mixed material containing part comprises the top and bottom that are fixedly connected with, upper end is upper and lower isodiametric tubular structure 1, lower end is the tubular structure 2 12 that from top to bottom diameter reduces gradually, has and cut off 13 between top and bottom, cuts off and on 13, has the aperture 14 being evenly distributed; The liquid portion of leaching comprises upper and lower, and top is the tubular structure 4 23 that from top to bottom diameter reduces gradually, and bottom is isodiametric tubular structure 5 24, and tubular structure 5 24 lower ends are inclined outlet.
