Description

A kind of novel suction filter funnel

Technical field

The utility model relates to filter technical field.Specifically a kind of novel suction filter funnel.

Background technique

Filtering is a kind of conventional solid-liquid separation means, is often used in the purification operations of product under lab.For Some easily separated solid-liquids select conventional funnel, but the solid and solution comparatively fine for some particles (crystal grain) It is necessary to using Buchner funnel (suction funnel) when separation.And existing Buchner funnel is due to built-in abacus, only orifice plate and drainage Cavity very difficulty or ease between pipe are cleaned, especially the inner wall of conical section, in the experimental implementation for needing to retain filtrate, filtrate It is easy to introduce new ion or substance because Buchner funnel does not wash clean clearly, and then causes the deviation or mistake of data.

Utility model content

For this purpose, the technical problem to be solved by the utility model is to provide a kind of novel suction filter funnels of easy cleaning, easily It is cleaned up in by the position contacted with filtrate, reduction introduces new impurity because not washing clean clearly, mentions for the accuracy of experiment For supporting.

In order to solve the above technical problems, the utility model provides the following technical solutions:

A kind of novel suction filter funnel, including drainage tube, taper collecting pipe, solution hold pipe, orifice plate and casing；The drainage The upper end of pipe is fixedly connected with the necking end of the taper collecting pipe, under the flared end and described sleeve pipe of the taper collecting pipe End is fixedly connected, and described sleeve pipe, which covers to hold on pipe in the solution and hold the seal of tube with the solution, to be connect；The orifice plate is set It sets to hold in pipe in the solution and hold pipe with the solution and be fixedly connected, the orifice plate is located at the solution and holds going out for pipe The top at liquid end.

Above-mentioned novel suction filter funnel, described sleeve pipe and the solution, which are held, is equipped with gasket ring between pipe.

Above-mentioned novel suction filter funnel, the gasket ring inner wall are equipped with the annular protrusion coaxial with the gasket ring.

Above-mentioned novel suction filter funnel, in the axial direction of the gasket ring, the inner wall of the gasket ring, which is equipped with, to be greater than Or it is equal to 2 annular protrusions.

Above-mentioned novel suction filter funnel, angle α between the gasket ring inner wall and the gasket ring bottom surface is 85~ 90°。

The technical solution of the utility model achieves following beneficial technical effect:

1. solution is held part to separate with filtrate collection part, so that can thoroughly clean inside suction funnel dry Only, it can not be cleaned up so as to avoid filtrate collection part in existing suction funnel, be easy to draw its remaining impurity in top Enter in filtrate, provides support to improve experiment accuracy.

2. solution being made to hold using gasket ring, sealing effect between pipe and casing is more preferable, while can make the two Between connection it is relatively firm, avoid solution and hold delamination between pipe and casing.

Detailed description of the invention

Fig. 2 is the enlarged structure schematic diagram in Fig. 1 at A；

Fig. 3 is the structural schematic diagram of the axial cross section part of the gasket ring in the novel suction filter funnel of the utility model.

Appended drawing reference indicates in figure are as follows: 1- drainage tube；2- taper collecting pipe；3- solution holds pipe；4- orifice plate；5- casing； 6- gasket ring；7- annular protrusion.

Specific embodiment

As shown in FIG. 1 to 3, the novel suction filter funnel of the utility model, including drainage tube 1, taper collecting pipe 2, solution Hold pipe 3, orifice plate 4 and casing 5；The upper end of the drainage tube 1 is fixedly connected with the necking end of the taper collecting pipe 2, described The flared end of taper collecting pipe 2 is fixedly connected with the lower end of described sleeve pipe 5,5 sets of described sleeve pipe hold on pipe 3 in the solution and Pipe 3 is held with the solution to be tightly connected；The setting of orifice plate 4 holds in pipe 3 in the solution and holds pipe 3 with the solution It is fixedly connected, the orifice plate 4 is located at the top that the solution holds the outlet end of pipe 3.Wherein, described sleeve pipe 5, the taper are converged Flow tube 2 and the drainage tube 1 can be processed into integral type.

Wherein in order to improve suction filtration efficiency, described sleeve pipe 5 and the leakproofness held between solution conduit are improved, is reduced close The dosage of oil sealing rouge, vaseline etc. in the present embodiment, holds in described sleeve pipe 5 and the solution and is equipped with gasket ring between pipe 3 6,6 inner wall of gasket ring is equipped with the annular protrusion 7 coaxial with the gasket ring 6, and in the gasket ring 6 In axial direction, the inner wall of the gasket ring 6 is equipped with 4 annular protrusions 7, and 6 inner wall of the gasket ring with it is described close Angle α between 6 bottom surface of packing ring is 85 °.

When being filtered using the utility model, first by 6 sets of the gasket ring in the lower end pipe for holding solution conduit On wall, then the lower end for holding solution conduit is put into described sleeve pipe 5 and is compressed, so that holding solution conduit for described with hand When lifting, described sleeve pipe 5 will not under the own wt effect of described sleeve pipe 5, the taper collecting pipe 2 and the drainage tube 1 It falls off.Then filter paper is placed on 4 top of orifice plate, then the utility model is placed in suction filtration system and carries out solid-liquid Lock out operation.When cleaning to the utility model, hold solution conduit and described sleeve pipe 5 separates for described, then respectively into Row cleaning, the comparison that can be cleaned various pieces in this way are clean.

Obviously, the above embodiments are merely examples for clarifying the description, and does not limit the embodiments.It is right For those of ordinary skill in the art, can also make on the basis of the above description it is other it is various forms of variation or It changes.There is no necessity and possibility to exhaust all the enbodiments.And it is extended from this it is obvious variation or It changes among still in present patent application scope of protection of the claims.
