Description

A wash sieve for determining soil mechanical composition experiment

Technical Field

The utility model relates to a sieve especially relates to a wash sieve for determining soil mechanical composition experiment, belongs to the experiment and washes sieve filtration equipment technical field.

Background

The mechanical composition of the soil refers to the ratio of different levels of soil particles with different sizes in the soil, and different soil particles have different mineral and chemical compositions. The mechanical analysis of soil is to divide the soil into several stages according to its size and to quantify them to obtain the mechanical composition of soil. For coarser soil particles (particle size >0.25 mm) it is common to sieve them out using a sieve with a certain pore size, while for finer soil particles (particle size <0.1 mm) it is difficult and inaccurate to sieve them, typically using a densitometer or a pipette method. However, both methods, for the classification of fine soil particles having a diameter of less than 0.25mm, use the hydrostatic sedimentation method according to the law of Ducheng. Both hydrometric and straw methods require chemical and physical treatment to disperse the soil, then sieve the sand (1-0.25 mm particle size) and prepare the suspension. The process of screening sand particles is important, generally, a funnel is placed on a 1000 ml measuring cylinder, a small copper sieve with the sieve pore diameter of 0.25mm is placed on the funnel, the cooled suspension in a triangular flask passes through the 0.25mm sieve, a rubber head glass rod is used for lightly scrubbing particles on the sieve, the particles are washed by distilled water, and the soil particles with the diameter of less than 0.25mm are all put into a settling cylinder until water flowing out of the sieve is clear. Traditional screening process is more loaded down with trivial details, will prepare the funnel, and the soil suspension of triangular flask is fallen to one hand, and another hand is held the glass stick and is washed and wipe soil particle, can not hold the water washing simultaneously. In addition, in the screening and washing process, the funnel wall is smooth, so that the screen is easy to overturn, and the problems are all problems to be solved.

Disclosure of Invention

The to-be-solved technical problem of the utility model is: the utility model provides a wash sieve for determining experiment of soil machine composition, through the side fixed connection cassette at the sieve, the card is on the graduated flask wall, and the sieve stretches into the top of graduated flask, fixes the flushing pipe on the cassette, establishes valve and shower nozzle on the pipe, the effectual problem of having solved above-mentioned existence.

The technical scheme of the utility model is that: the utility model provides a wash sieve for determining experiment of soil mechanical composition, it includes sieve wall, sieve end and cassette, the sieve wall is the cylinder structure, at the bottom of the bottom fixed connection sieve of sieve wall, establishes a plurality of sieve meshes on the sieve end, fixed connection cassette on the lateral wall of sieve wall, the cassette is the type of falling U structure, has the draw-in groove in the centre of cassette, fixed connection inlet tube on the lateral wall of cassette, inlet tube one end connection valve, other end threaded connection has the nozzle.

The clamping seat is of an arc-shaped structure in a plan view and matched with the radian of the measuring cylinder wall, and a rubber pad is bonded on the inner side wall of the clamping seat.

The nozzle is positioned directly above the middle of the screen wall.

The sieve holes are 60 meshes and 0.25mm in pore diameter, are in square structures and are uniformly distributed on the sieve bottom.

The utility model has the advantages that: compared with the prior art, adopt the technical scheme of the utility model, work efficiency that can be convenient, the efficient improves the experiment. Firstly, the size of the washing sieve can be just increased to the top of the measuring cylinder, and the cleaned soil suspension can directly enter the measuring cylinder without transferring again. Secondly, the device is connected with the water purification machine, and can automatically drip washing the soil suspension through controlling the valve without manually washing, thereby saving time. And the outer wall of the washing sieve is provided with a fixed U-shaped clamping seat, and the clamping seat is hung on the inner wall of the measuring cylinder during working, so that the clamping seat is very stable, the risk of being overturned is reduced, and the safe experiment is ensured. Finally, the device is simple, low in manufacturing cost, clean and convenient to maintain, effectively improves the working efficiency of the experiment, and is relatively suitable for the experiment of measuring the soil mechanical composition by the traditional method.
