Abstract

The utility model relates to a sieve capable of regulating the sizes of sieve pores, which comprises an internal sieve barrel and an external sieve barrel. The barrel walls of the internal sieve barrel and the external sieve barrel are respectively provided with internal sieve pores and external sieve pores with different shapes. By rotating and regulating the internal sieve barrel and the external sieve barrel, the size of actual pores, which is obtained by making the sizes of the sieve pores on the barrel walls of the internal sieve barrel and the external sieve barrel matched mutually, is smaller than the size of one material in two mixed materials, but larger than the size of the other material so as to reach the sieving effect. The sieve of the utility model has the advantages of simple structure and convenient use and operation.

Description

A kind of sieve of adjustable sieve hole size

Technical field

The utility model relates to a kind of sieve, is specifically related to a kind of sieve of adjustable sieve hole size.

Background technology

Sieve is a kind of utensil that screens out flour or filter liquid of specializing in, and the size of its sieve aperture so just can reach the effect that screens out less than the size of a kind of material in two kinds of compounding substances and greater than the size of another kind of material.The slot size of sieve is fixed at present, and when needs were separated two kinds of materials with sieve, these two kinds of materials had size all less than the situation of slot size, will reselect sieve, so just so that the use of sieve is very inconvenient; If limit in addition the size of sieve aperture by means of other instrument, complex structure and the so suitable instrument of difficult searching, it is more inconvenient to operate.

Summary of the invention

The deficiency that exists in order to overcome above-mentioned prior art, the purpose of this utility model is to provide a kind of sieve of adjustable sieve hole size, regulate interior sieve bucket by rotation, slot size on the bucket wall of interior sieve bucket and outer sieve bucket is cooperatively interacted and the size of actual apertures less than the big or small of a kind of material in two kinds of compounding substances and greater than the size of another kind of material, so just can reach the effect that screens out, and simple in structure, use and operate all very convenient.

In order to achieve the above object, the technical scheme that the utility model adopted is:

A kind of sieve of adjustable sieve hole size comprises interior sieve bucket 1 and outer sieve bucket 2, has difform interior sieve aperture 3 and outer sieve aperture 4 on the bucket wall of interior sieve bucket 1 and outer sieve bucket 2.

The bucket wall of described interior sieve bucket 1 evenly has at least two interior sieve apertures 3, and described interior sieve aperture 3 is the base equilateral triangle parallel with the central axis of interior sieve bucket 1; The bucket wall of described outer sieve bucket 2 evenly has at least two rectangular outer sieve apertures 4, the width of described outer sieve aperture 4 equates with the width of interior sieve aperture 3, the longitudinal separation of two adjacent outer sieve apertures 4 and the lateral separation respectively longitudinal separation with adjacent two interior sieve apertures 3 are consistent with the lateral separation, and the outside diameter of the interior circular diameter of described outer sieve bucket 2 and interior sieve barrel 1 equates.

By interior sieve bucket 1 is built in the outer sieve bucket 2, sieve bucket 1 and outer sieve bucket 2 in rotation is regulated then, slot size on the bucket wall of interior sieve bucket 1 and outer sieve bucket 2 is cooperatively interacted and the size of actual apertures less than the size of a kind of material in two kinds of compounding substances and greater than the size of another kind of material, so just can reach the effect that screens out, and simple in structure, use and operate all very convenient.

To be respectively the equilateral triangle and the rectangle structure that are evenly distributed on barrel wall more simple for the outer sieve aperture 4 of the interior sieve aperture 3 of sieve bucket 1 and outer sieve bucket 2 in addition; The width of outer sieve aperture 4 equates with the width of interior sieve aperture 3, the longitudinal separation of two adjacent outer sieve apertures 4 and the lateral separation respectively longitudinal separation with adjacent two interior sieve apertures 3 are consistent with the lateral separation, the characteristics that the interior circular diameter of outer sieve bucket 2 equates with the outside diameter of interior sieve bucket 1 are so that interior sieve bucket 1 and the 2 easier sealings before screening out of outer sieve bucket, easier interior sieve aperture 3 and the outer sieve aperture 4 of suiting during use causes the more convenient needed actual apertures size that obtains.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is described in more detail.

As shown in Figure 1 and Figure 2, the sieve of adjustable sieve hole size comprises interior sieve bucket 1 and outer sieve bucket 2, and the bucket wall of interior sieve bucket 1 evenly has at least two interior sieve apertures 3, and interior sieve aperture 3 is the base equilateral triangle parallel with the central axis of interior sieve bucket 1; The bucket wall of outer sieve bucket 2 evenly has at least two rectangular outer sieve apertures 4, the width of outer sieve aperture 4 equates with the width of interior sieve aperture 3, the longitudinal separation of two adjacent outer sieve apertures 4 and the lateral separation respectively longitudinal separation with adjacent two interior sieve apertures 3 are consistent with the lateral separation, and the outside diameter of the interior circular diameter of outer sieve bucket 2 and interior sieve barrel 1 equates.Such structure is so that the 2 easier sealings before screening out of interior sieve bucket 1 and outer sieve bucket, and easier interior sieve aperture 3 and the outer sieve aperture 4 of suiting during use causes the more convenient needed actual apertures size that obtains.

Operation principle of the present utility model is: during use, earlier interior sieve bucket 1 is placed in the outer sieve bucket 2, sieve bucket 1 in the rotation, the interior sieve aperture 3 on the interior sieve bucket 1 and the outer outer sieve aperture 4 that sieves on the bucket 2 are staggered, seal to guarantee sieve.Behind the compounding substances that the two kinds of materials that will separate of packing into form, again sieve bucket 1 in the rotation, the actual apertures size that interior sieve aperture 3 and outer sieve aperture 4 is cooperated and obtain is less than the size of a kind of material in two kinds of compounding substances and greater than the size of another kind of material, can filter and separates.So just can reach the effect that screens out, and simple in structure, use and operate all very convenient.
