Abstract

The utility model discloses a collecting and screening device. The device comprises a screen body and dismountable screen nets; a sampling device is connected to the upper end of the screen body; the screen body comprises three parts, namely, an upper part, a medium part and a lower part; each part is in threaded connection; the dismountable screen nets are arranged in the upper part and the medium part; the aperture of meshes of the dismountable screen net in the upper part is more than that of the dismountable screen net in the medium part; magnets are arranged on the sidewall and the bottom part of the screen body. The collecting and screening device is simple to operate; samples can be directly collected and screened, and thus both time and force can be saved; in addition, the samples can be screened into three particles of different aperture at the same time; the samples can be discharged by opening a spiral opening after screening is done; the bottom end of the device is arranged like an arc-shaped corner which avoids dead corner, and the samples are uneasy to be damaged.

Description

A kind of collection screening plant

Technical field

The utility model discloses a kind of collection screening plant, belong to laboratory equipment technical field.

Background technology

In laboratory; we often can choose some and be applicable to the sample of testing ourselves; especially the stricter experiment of ask for something; may also there is requirement to the granular size of sample; this is just to need us to sample, to screen; but at present the screening plant in laboratory is all first with putting into screen cloth after sampler sampling, also needs to place gathering-device under screen cloth, troublesome poeration and easily lose sample.

Sometimes also need the outdoor collected specimens of carrying out, at this moment just need to carry out pretreatment to sample, remove some larger impurity etc., so just can screen gathering sample.

Need provide a kind of and integrate sampling and screen, easy to operate, time saving and energy saving device.

Utility model content

The utility model provides a kind of collection screening plant, has solved the problem of conventional screen screening device troublesome poeration.

In order to address the above problem, the technical solution of the utility model is as follows: a kind of collection screening plant, by sieve nest 1 and detachable screen cloth 2, formed, sieve nest 1 upper end connects sampler 3, sieve nest 1 is comprised of upper, middle, and lower part, every part connects by engage thread, in upper part and middle partial interior, is respectively equipped with detachable screen cloth 2, and detachable screen cloth 2 apertures of upper part are greater than detachable screen cloth 2 apertures of middle part; On the sidewall of sieve nest 1, be equipped with magnet 5 with bottom.

On the sidewall of above-mentioned sieve nest 1 and bottom is equipped with magnet 5, can remove the irony impurity in sample.

Arc turning is arranged in the bottom of 1 time part of above-mentioned sieve nest, can not produce dead angle like this, topples over sample conveniently, does not lose sample.

The above-mentioned detachable screen cloth 2 as required aperture of sample is adjusted.

Collection screening plant of the present utility model, simple to operate, directly collected specimens can be screened, time saving and energy saving, and can simultaneously sample sifter the be hanked particle of 3 kinds of different pore sizes of the utility model, after having screened, by spiral mouth, opening is pourable sample, and device bottom be arranged to arc turning, can not produce dead angle like this, be not easy to lose sample.

Accompanying drawing explanation

Fig. 1 is front view of the present utility model;

(1, sieve nest; 2, detachable screen cloth; 3, sampler; 4, spiral mouth; 5, magnet).

Fig. 2 is side view of the present utility model;

The specific embodiment

Below in conjunction with Figure of description, the utility model is further explained.

As shown in Figure 1, 2, a kind of collection screening plant, a kind of collection screening plant, by sieve nest 1 and detachable screen cloth 2, formed, sieve nest 1 upper end connects sampler 3, and sieve nest 1 is comprised of upper, middle, and lower part, and every part connects by engage thread, in upper part and middle partial interior, be respectively equipped with detachable screen cloth 2, detachable screen cloth 2 apertures of upper part are greater than detachable screen cloth 2 apertures of middle part; On the sidewall of sieve nest 1, be equipped with magnet 5 with bottom.

In use, with sampler 3, sample, device is upright, slowly shaking device can carry out screening sample, after having screened, first slowly spiral mouth 4 is below opened, the sample of the particle aperture minimum of lower part is poured out, slowly open again spiral mouth above, the sample of middle part is poured out, finally pour out the sample of part.Detachable screen cloth 2 can be changed according to actual needs, needs how wide-aperture sample particle, just changes how wide-aperture screen cloth, easy to use.Arc turning is arranged in the bottom of lower part, can not produce dead angle like this, is not easy to lose sample.And be equipped with magnet 5 with bottom on the sidewall of sieve nest 1, and can remove like this irony impurity in sample, guarantee the purity of sample, to guarantee the accuracy of experimental result.

The utility model not only can be applied to, in laboratory, also can be applied to outdoor collected specimens, and build is small and exquisite, easy to carry, easy to use.

Claims
