Description
Technical Field
The utility model belongs to the technical field of soil sample detects, especially indicate a wash sieve funnel that uses with graduated flask cooperation.
Background
The particle size distribution range of the soil particles is wider, wherein the soil with phi larger than 60mm is large-grained soil, the soil with phi larger than 0.075mm and phi smaller than 60mm is coarse-grained soil, and the soil with phi smaller than 0.075mm is fine-grained soil. Wherein the particles less than 0.075mm can be divided into particles (0.002 mm < phi < 0.075 mm) and adhesive particles (phi < 0.002 mm). When the particle diameter of more than 0.075mm exceeds 15% of the total mass of the sample, a screening test is carried out to analyze the particle diameter distribution range and the proportion of particles with the diameter of more than 0.075mm, and then a densimeter test is carried out to analyze the particle diameter distribution range and the proportion of particle groups with the diameter of less than 0.075 mm.
A washing sieve funnel, even washing sieve funnels with different diameters, is needed to assist in completing the test in densitometer analysis tests and other related test processes. In practice, a reduced version of the standard test sieve device is made of stainless steel and does not allow for the special use scenario of a glass instrument such as a measuring cylinder, and therefore has the following disadvantages: (1) the filter screen setting of current sieve washing funnel is in upper and lower cup body handing-over department, and has corresponding connection plane between filter screen and the cup body, and this just leads to here probably to silt up or hide the minor diameter soil grain in the soil. The accuracy of the test is reduced. (2) The potential safety hazard is increased by materials such as stainless steel. During the test, the sieve washing funnel is made of stainless steel, the measuring cylinder is made of glass, and the slight collision between the sieve washing funnel and the measuring cylinder can cause the measuring cylinder to be cracked. (3) The diameter of the washing screen is single. Various sizes of sieve washing funnels are often required in daily experiments, but the sieve washing funnels are difficult to purchase and occupy large storage space when not used. If can realize the change of not unidimensional filter screen, will alleviate test device's storage greatly, also promoted the convenience of device.
