Abstract
The utility model discloses a kind of dismountable Buchner funnel being applicable to wide neck flask, comprise turbination cylinder and cylinder, described turbination cylinder inwall top end has a circle annular boss, circumferential edge along described turbination cylinder is provided with hoop projection, the tapering of described turbination cylinder is 30 ~ 60 degree, the outer surface frosted process of turbination cylinder; The annular boss of described turbination cylinder shelves removable filter plate, described filter has some filter bores; Described cylinder is the tubular structure of upper and lower opening, and described cylinder to be inserted in hoop projection the protruding interference fit with hoop, and is shelved on filter.Structure is simple, be convenient to cleaning, can ensure sealing simultaneously, easy to use.
Description
Technical field
The utility model relates to the Buchner funnel that a kind of analysis design mothod is used, especially a kind of dismountable Buchner funnel being applicable to wide neck flask.
Background technology
Buchner funnel is the one pottery instrument used in laboratory, also useful plastic production, is used for using vacuum or negative pressure suction to filter.Shape is oblate tubular, cylinder bottom surface has been opened a lot of aperture, the tubular outlet that one, lower company is long and narrow.When using, general first filter paper on the pad of cylinder bottom surface, injects Bu Shi flask upper opening and by sealing joint (such as using rubber ring) by funnel.The side mouth of Bu Shi beaker connects extract system.Then pour the solid for being separated, liquid mixture into top, liquid component is drawn into beaker under negative pressure effect, and top stayed by solid.But when cleaning, tubular outlet long and narrow below Buchner funnel is difficult to thoroughly clean up, and particularly for some stickums, cleaning up is very difficult.
Utility model content
For solving the problems of the technologies described above, the utility model provide a kind of structure simple, be convenient to cleaning, sealing, dismountable Buchner funnel being applicable to wide neck flask easy to use can be ensured simultaneously.
The technical solution of the utility model is as follows: a kind of dismountable Buchner funnel being applicable to wide neck flask, comprise turbination cylinder and cylinder, described turbination cylinder inwall top end has a circle annular boss, circumferential edge along described turbination cylinder is provided with hoop projection, the tapering of described turbination cylinder is 30 ~ 60 degree, the outer surface frosted process of turbination cylinder; The annular boss of described turbination cylinder shelves removable filter plate, described filter has some filter bores; Described cylinder is the tubular structure of upper and lower opening, and described cylinder to be inserted in hoop projection the protruding interference fit with hoop, and is shelved on filter.
As preferably, described dismountable Buchner funnel being applicable to wide neck flask, adopts plastics, metal or pottery to make, manufacture simple, cost is low, durable, convenient cleaning.
The beneficial effects of the utility model are: structure is simple, be convenient to cleaning, can ensure sealing simultaneously, easy to use, are particularly useful for using on wide neck flask.Owing to eliminating the sharp mouth portion below traditional Buchner funnel, when making extracting, flow rate of liquid is accelerated, and shortens filtration time.Turbination cylinder adopts frosted process, improves sealing, makes extracting more efficient.Detachably, make cleaning convenient, more easy cleaning is clean, and the hoop projection of turbination cylinder can prevent cylinder from dropping, and ensure that safety during use for cylinder and filter.

Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail:
The dismountable Buchner funnel being applicable to wide neck flask of the utility model as Figure 1-4, is made up of turbination cylinder 1, cylinder 2 and filter 3, filter 3 has some filter bores 3a.Cylinder and filter detachably, make cleaning more convenient, clean cleaner, prevent cross pollution when filtering different material.
Turbination cylinder 1 inwall top end has a circle annular boss 1a, and the circumferential edge along turbination cylinder 1 is provided with the protruding 1b of hoop, and the tapering of turbination cylinder 1 is 40 degree, nozzle is large, be particularly useful for wide neck flask, when making extracting, flow rate of liquid is accelerated simultaneously, shortens filtration time.The outer surface frosted process of turbination cylinder 2 improves sealing, makes extracting more efficient.Filter 3 is held on the annular boss 1a of turbination cylinder 1; Cylinder 2 is the tubular structure of upper and lower opening, and cylinder 2 is inserted in 1b interference fit protruding with hoop in the protruding 1b of hoop, and is shelved on filter 3.The protruding 1b of hoop prevents cylinder 2 from dropping, and interference fit strengthens connection, ensure that sealing.
As preferably, this dismountable Buchner funnel being applicable to wide neck flask, adopts plastics, metal or pottery to make, manufacture simple, cost is low, durable, convenient cleaning.
Be held on the annular boss 1a of turbination cylinder 1 by filter 3 during use, cylinder 2 is inserted in turbination cylinder 1 and is shelved on filter 3, and the solidliquid mixture that will filter pours funnel into, can start extracting.After extracting terminates, taken out by Buchner funnel, dismounting, pours out solid matter, cleans.
