Abstract

The utility model discloses one kind combination sub-sieve, including：Inner and outer sieve, the interior sieve is removably enclosed within inside the outer sieve, and the mesh of the interior sieve is 30 mesh, and the mesh of the outer sieve is 60 mesh.It is arranged such, the combination sub-sieve that the utility model is provided, it is higher that it is separated by filtration efficiency.

Description

One kind combination sub-sieve

Technical field

The utility model is related to sub-sieve technical field, more specifically to one kind combination sub-sieve.

Background technology

In benthon is investigated, current most common method is that the bottom in investigation place is taken with the bottom sampler of certain specification Mud sample, takes back laboratory and is processed.Treating method is that mud sample is placed in 60 mesh sub-sieves, is incited somebody to action with after clear water washing and filtering Remaining mixture is poured into pallet and selected.But when directly being filtered with 60 mesh sub-sieves, many large granular impurities, grass cuttings etc. Mixture block mesh, cause that single treatment mud sample can not excessively and rate of filtration is slow, in mud sample biological and impurity be Energy quick separating, efficiency is low.

Therefore, how to solve in the prior art, sub-sieve single treatment mud sample is less, be separated by filtration the low problem of efficiency, As those skilled in the art's important technological problems to be solved.

The content of the invention

In view of this, the purpose of this utility model is to provide a kind of combination sub-sieve, and it is higher that it is separated by filtration efficiency.

A kind of combination sub-sieve that the utility model is provided, including：Inner and outer sieve, the interior sieve is removably enclosed within institute State inside outer sieve, the mesh of the interior sieve is 30 mesh, and the mesh of the outer sieve is 60 mesh.

Preferably, the interior sieve and the outer sieve are cylinder-like structure, and the side wall and bottom wall of the interior sieve are equipped with Mesh, the bottom wall of the outer sieve is provided with mesh.

Preferably, the interior sieve is stuck in the outer sieve by buckle.

Preferably, the interior sieve is hung in the outer sieve by hook.

Preferably, wall edge of the wall edge of the interior sieve less than the outer sieve.

Preferably, the internal diameter of the interior sieve is smaller 1-2 centimetres than the internal diameter of the outer sieve.

When the combination sub-sieve provided using the utility model carries out filtered sample, sample can be put into interior sieve first In, interior sieve may filter that thicker impurity, and outer sieve is further filtered, and remaining sample is poured into pallet again to be selected.So set Put, the combined type sub-sieve that the utility model is provided has simple structure, easy to operate, can quick separating mud sample, raising work Efficiency, time saving and energy saving advantage.

Brief description of the drawings

In order to illustrate more clearly of the utility model embodiment or technical scheme of the prior art, below will be to embodiment Or the accompanying drawing to be used needed for description of the prior art is briefly described, it should be apparent that, drawings in the following description are only It is some embodiments of the present utility model, for those of ordinary skill in the art, is not paying the premise of creative work Under, other accompanying drawings can also be obtained according to these accompanying drawings.

Fig. 1 is the schematic diagram of combination sub-sieve in the utility model embodiment.

Specific embodiment

A kind of combination sub-sieve that this specific embodiment is provided, it is higher that it is separated by filtration efficiency.

Hereinafter, embodiment is illustrated referring to the drawings.Additionally, embodiments illustrated below is not to described in claim Utility model content rise any restriction effect.In addition, the full content of the composition represented by example below is not limited to conduct Necessary to the solution of the utility model described in claim.

Refer to Fig. 1, the combination sub-sieve that the present embodiment is provided, including buckle 1, interior sieve 2, outer sieve 3.Interior sieve 2 and outer sieve 3 Can be detachably connectable by buckle 1, certainly, can also be connected otherwise, such as, by hook mode.

Interior sieve 2 is the sub-sieve of 30 mesh, and outer sieve 3 is the sub-sieve of 60 mesh, and so, sample can first pass through the thick of interior sieve 2 Sieve, then by the dusting cover treatment of outer sieve, can so effectively improve screening efficiency.

The wall edge of interior sieve 2 slightly below outer can sieve 3, to avoid the sample in interior sieve 2 from being spilled over to the outside of sample sifter.

The internal diameter of interior sieve 2 can be 30 eye mesh screens than the outer sieve small 1~2cm of 3 internal diameters, sieve wall and the sieve bottom of interior sieve 2；Outer sieve 3 sieve wall can be solid aluminium alloy circle, and sieve bottom is 60 eye mesh screens.

When the combination sub-sieve provided using the present embodiment carries out filtered sample, sample can be put into interior sieve 2 first, Interior sieve 2 may filter that thicker impurity, and outer sieve 3 is further filtered, and remaining sample is poured into pallet again to be selected.So set Put, the combined type sub-sieve that the present embodiment is provided has simple structure, easy to operate, can quick separating mud sample, raising work effect Rate, time saving and energy saving advantage.

The foregoing description of the disclosed embodiments, enables professional and technical personnel in the field to realize or new using this practicality Type.Various modifications to these embodiments will be apparent for those skilled in the art, determine herein The General Principle of justice can in other embodiments be realized in the case where spirit or scope of the present utility model are not departed from.Cause This, the utility model is not intended to be limited to the embodiments shown herein, and is to fit to and principles disclosed herein The most wide scope consistent with features of novelty.
