It is equipped with top docking port 23.The top of bottom container 10 is provided with the bottom docking port 14 for being docked with top docking port 23.
Docked between top docking port 23 and bottom docking port 14 by way of grafting or screw thread.
Upper container 20 and bottom container 10 are transparent vessel in the present embodiment, and intermediate density liquid is transparent liquid
Body.The both sides at the middle part of separation container 30 are respectively arranged with Optical Transmit Unit 32 and light receiving unit 33.Optical Transmit Unit 32 is sent out
The light beam penetrated exposes to light receiving unit 33 through separation container 30.Light receiving unit 33 is sent out according to light beam through separation container 30
Raw decay judges whether the dry sand to be measured in separation separates completion.
During separation container 30 separates sandstone and soil, sandstone is dispersed in intermediate density liquid first
In, now the translucency of separation container is worst, and decay when passing through separation container of light is maximum.With the sandstone in dry sand to be measured
Precipitation, soil float, and the translucency at the middle part of separation container 30 gradually strengthens, and the decay of light also tends to stabilization.When through separation
When the attenuation rate of the light of container tends towards stability, you can judge that the sandstone in separation container and soil separation are completed.
As shown in Figure 3 and Figure 4, upper container lid 24 is used to block top docking port 23;Bottom container lid 15 is used to block
Bottom docking port 14.
As shown in Figure 3 and Figure 4, separating tank 40 is built with intermediate density liquid 41.Separating tank 40 is used in described point of separation
From the intermediate density liquid and mud kept during the upper container 20 and bottom container 10 of container 30 in upper container 20
Soil is undisturbed.
Equipment for separating liquid from solid is used to separate the sandstone or soil in intermediate density liquid.Separation of solid and liquid is filled in the present embodiment
Put including filter device and drying unit.The sandstone or soil being woven into intermediate density liquid are obtained after filtering and drying
To dry sandstone or soil.Solid weight meausring apparatus is used to weigh dried sandstone or soil weight.
The advantageous effects of silt test instrument are in the dry sand of the present invention:According to sand and stone flour and native apparent density
The method of interstitial fluid flotation separates sand and stone flour with soil in difference, utilization, the clay content of accurate measurement sand.Use this method can be with
Quickly, clay content accurately, in quantitative measurment river sand, Machine-made Sand.Avoid the deficiency of sieve formula or methylene blue method.
Clay content measuring method in the dry sand of the present invention is introduced below in conjunction with the accompanying drawings:
