Description
Technical field
The utility model belongs to the detection technique field, is specifically related to a kind of pick-up unit that is used for the measure solid material density.
Background technology
In the detection technique field, the density of measuring common liq can adopt densitometer, directly densitometer is put into liquid and just can measure by reading.For the irregular solid matter of profile; Like particulate material; Usually the simplest method is exactly earlier particle to be weighed, and puts it into the graduated cylinder that liquid is housed then, observes the recruitment of liquid volume in the graduated cylinder; The volume recruitment of liquid is exactly the volume of particle, thereby just calculates the density of particle divided by volume with the quality of particle.This kind method is simple, but because the recruitment of the interior liquid volume of graduated cylinder need be leaned on range estimation, and the data of estimating out are because of method and people's different differences to some extent, therefore, the density of the solid matter of measuring is inaccurate.
The utility model content
The utility model technical matters to be solved provides a kind of accurately pick-up unit of measure solid material density.
The utility model solves the technical scheme that its technical matters adopted: be used for the pick-up unit of measure solid material density, comprise weighing apparatus, also comprise the container of dull and stereotyped and open upper end, container places on the weighing apparatus and the port of container closely contacts with dull and stereotyped.
Wherein, the bottom of container is provided with support.
Further, support is an A-frame.
Further again, A-frame and container are integral structure.
The beneficial effect of the utility model is: through container dull and stereotyped and open upper end is set, and the port of container closely contacts with flat board, can behind the container filled with fluid, compress with flat board; Air in the amount discharge container, the volume number that container is packed at every turn equate, thereby have avoided coming measurement volumes with the method for range estimation; Quality through accurate measurement discharged liquid; Thereby trying to achieve the volume of discharged liquid, promptly is the volume of solid matter, further tries to achieve the density of solid matter.Be specially: 1, use the quality of weighing apparatus weighing solid matter to be m
12, container is placed on the weighing apparatus, and in container, fill it up with liquid, solid matter is put into container; Compress with flat board; Air in the amount discharge container is dried on the weighing apparatus liquid with container outer surface, and the liquid and the dull and stereotyped weight that take by weighing in container, solid matter, the container are m
23, do not put solid matter, in container, fill it up with liquid, compress with flat board, the air in the amount discharge container is dried on the weighing apparatus liquid with container outer surface, and the liquid and the dull and stereotyped weight that take by weighing in container, the container are m
3According to formula:
can calculate the density of solid matter.Utilize the device of the utility model, measuring process is simple, and the solid matter density of measurement is accurate.In addition, the utility model is provided with support in the bottom of container, can easily the liquid of overflow container be dried, and avoids the error that causes because of the error of operating.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Be labeled as among the figure: weighing apparatus 1, container 2, flat board 3, support 4.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As shown in Figure 1, the pick-up unit that is used for the measure solid material density of the utility model comprises weighing apparatus 1, also comprises the container 2 of flat board 3 and open upper end, and container 2 places on the weighing apparatus 1 and the port of container 2 closely contacts with dull and stereotyped 3.Through be provided with dull and stereotyped 3 with the container 2 of open upper end, and the port of container 2 closely contacts with dull and stereotyped 3, can behind container 2 filleds with fluid, compress with flat board 3; Air in the amount discharge container 2, the volume number that container 2 is packed at every turn equate, avoid coming measurement volumes with the method for range estimation; Quality through accurate measurement discharged liquid; Thereby trying to achieve the volume of discharged liquid, promptly is the volume of solid matter, further tries to achieve the density of solid matter.Be specially: a, use the quality of weighing apparatus 1 weighing solid matter to be m
1B, container 2 is placed on the weighing apparatus 1, and keep horizontal positioned, in container 2, fill it up with liquid; Solid matter is put into container 2 also to be rocked gently; The solid matter ambient air is overflowed, compress the air in the amount discharge container 2 with dull and stereotyped 3; Dry on the weighing apparatus 1 liquid with container 2 outside surfaces, the liquid and dull and stereotyped 3 the weight that take by weighing in container 2, solid matter, the container 2 are m
2C, do not put solid matter, in container 2, fill it up with liquid, compress with dull and stereotyped 3, the air in the amount discharge container 2 is dried on the weighing apparatus 1 liquid with container 2 outside surfaces, and the liquid and dull and stereotyped 3 the weight that take by weighing in container 2, the container 2 are m
3According to formula:
can calculate the density of solid matter; Process is simple, and the density of measurement is accurate.In the formula, m
3+ m
1-m
2Be the quality that adds the liquid of discharging after the solid matter, the quality of the liquid of discharge is the volume of discharged liquid divided by density of liquid, and the volume of discharged liquid just equals the volume of solid matter, thereby with the quality m of solid matter
1Just obtain the density of solid matter divided by the volume of solid matter.It will be understood by those skilled in the art that; Can not be compatible between solid matter described in the utility model and the liquid; For example, if what pack in the container is the density that this liquid of water comes the measure solid material, so this solid matter should be non-water-soluble solid matter; If this material is water miscible, so just should replace with other liquid.The position relation of the weighing apparatus 1 that the utility model is described, container 2 and flat board 3 is position relations in use, is not the position relation of fixing, and is being under the non-working condition and can separately depositing.
The utility model preferably is provided with support 4 in the bottom of container 2.Because after covering dull and stereotyped 3, liquid can overflow from the edge of container 2 openings and make and can be stained with liquid on outside face and the weighing apparatus 1 of container 2, at this moment, should dry all liq that overflows, otherwise, the m of measurement
2Weight just be not liquid and dull and stereotyped 3 general assembly (TW) in container 2, solid matter, the container 2, the m of measurement
3Weight equally just be not liquid and dull and stereotyped 3 general assembly (TW) in container 2, the container 2 yet; Will make the density of the solid matter of trying to achieve inaccurate like this; Therefore, the utility model is provided with support 4 in the bottom of container 2, thereby easily the liquid of overflow container 2 is dried; Avoid the error that causes of error, make that the density of the solid matter measured is more accurate because of operation.Further, place steadily in order to guarantee container 2, the liquid in covering after dull and stereotyped 3 amount discharge container 2 fully, said support 4 is an A-frame.Further again, said A-frame and container are integral structure, thus can be more convenient dry liquid, avoid producing between support 4 and the container 2 the not dead angle of easy to clean liquid.The utility model be used for the pick-up unit of measure solid material density easy and simple to handle, measure accurately.
