Below in conjunction with accompanying drawing, silt test instrument in dry sand of the present invention is introduced:
As shown in Figures 1 to 4, in dry sand of the present invention, silt test instrument is for measuring the silt content in dry sand to be measured, comprises sandstone and earth in dry sand to be measured, and the apparent density of sandstone is greater than the apparent density of earth.In dry sand of the present invention, silt test instrument comprises: separation container 30, upper container lid 22, bottom container lid 15, separating tank 40, equipment for separating liquid from solid and solid weight meausring apparatus.
As shown in Figures 2 and 3, separation container 30 utilizes sandstone and earth in intermediate density fluid separation applications dry sand to be measured.The density of intermediate density liquid is less than the apparent density of sandstone and is greater than the apparent density of earth.The density of intermediate density liquid is 2.0g/cm in the present embodiment
3.Separation container 30 comprises upper container 20 and bottom container 10, and the top of upper container 20 is provided with the inlet 21 for intermediate density liquid of annotating, and inlet 21 is provided with gland bonnet 22.The bottom of upper container 20 is provided with top docking port 23.The top of bottom container 10 is provided with the bottom docking port 14 for docking with top docking port 23.Docked by the mode of grafting or screw thread between top docking port 23 and bottom docking port 14.
Upper container 20 and bottom container 10 are transparent vessel in the present embodiment, and intermediate density liquid is transparency liquid.Both sides in the middle part of separation container 30 are respectively arranged with Optical Transmit Unit 32 and light receiving unit 33.The light beam that Optical Transmit Unit 32 is launched exposes to light receiving unit 33 through separation container 30.Through the decay that separation container 30 occurs, light receiving unit 33 judges whether the dry sand to be measured in separation has been separated according to light beam.
In the process that separation container 30 is separated sandstone and earth, be first dispersed in by sandstone in intermediate density liquid, now the light transmission of separation container is the poorest, light through separation container time decay maximum.Along with the sandstone precipitation in dry sand to be measured, earth float, the light transmission in the middle part of separation container 30 strengthens gradually, and the decay of light also tends towards stability.When the attenuation rate of the light through separation container tends towards stability, can judge that the sandstone in separation container has been separated with earth.
As shown in Figure 3 and Figure 4, upper container lid 22 is for shutoff top docking port 23; Bottom container lid 15 is for shutoff 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 not subject to disturbance for keeping the intermediate density liquid in upper container 20 and earth in the upper container 20 being separated described separation container 30 and bottom container 10 process.
Equipment for separating liquid from solid is for separating of the sandstone in intermediate density liquid or earth.Equipment for separating liquid from solid comprises filter device and drying unit in the present embodiment.Be woven into sandstone in intermediate density liquid or earth obtains dry sandstone or earth after filtering and drying.Solid weight meausring apparatus is for weighing dried sandstone or earth weight.
In dry sand of the present invention, the Advantageous Effects of silt test instrument is: according to the difference of sand and stone flour and native apparent density, utilize the method for intermediate liquid flotation sand and stone flour to be separated with soil, accurately measures the silt content of sand.Adopt this method can silt content fast, in accurate, quantitative measurment river sand, Machine-made Sand.Avoid the deficiency of sieve formula or methylene blue method.
Silt content measuring method in dry sand of the present invention is introduced below in conjunction with accompanying drawing:
1) loading weight in lower portion container 10 is as shown in Figure 1 m
1dry sand to be measured 11.Dry sand 11 to be measured weighing before through drying and processing.
2) as shown in Figures 2 and 3, upper container 20 and bottom container 10 are docked formation separation container 30.
3) as shown in Figure 3, in separation container 30, intermediate density liquid 31 is filled.First the gland bonnet 22 of the inlet 21 of upper container 20 is opened in the process of filling intermediate density liquid 31; To be annotated in separation container 30 intermediate density liquid 31 by inlet 21 subsequently; After having annotated, gland bonnet 22 is mounted to the inlet 21 of upper container 20.
Rear use intermediate density liquid 31 of having annotated is separated sandstone 12 in dry sand 11 to be measured and earth 13.In detachment process, first rock separation container 30, dry sand 12 to be measured is dispersed in intermediate density liquid 31.Standing separation container 30 subsequently, makes sandstone 12 be separated with earth 13.The light beam using Optical Transmit Unit 32 to launch to separation container 30 in the process left standstill, and use light receiving unit 33 to receive light beam through separation container 30, use light receiving unit 33 to judge whether the dry sand to be measured in separation has been separated according to light beam through the decay that separation container 30 occurs.Be separated and terminate the bottom that rear sandstone 12 is deposited in separation container 30, earth 13 floats over the top of separation container 30.
4) as shown in Figure 4, separation container 30 is soaked in the intermediate density liquid 41 in separating tank 40, under the state of soaking, be separated upper container 20 and the bottom container 10 of separation container 30, use upper container lid 22 and bottom container lid 15 closed upper portion container 20 and bottom container 10 subsequently respectively.The posture that upper container 20 and bottom container 10 can make the top docking port 23 of upper container 20 keep down in detachment process is separated in the intermediate density liquid 41 of separating tank 40.Due in the intermediate density liquid 41 that soaks, even if Open Side Down, the intermediate density liquid in upper container 20 and earth also can not flow out in detachment process again.
6) use the sandstone in equipment for separating liquid from solid separation bottom container, and use solid weight meausring apparatus to measure the weight m of sandstone
2;
7) use the earth in equipment for separating liquid from solid separation upper container, and use solid weight meausring apparatus to measure the weight m of earth
3.
