Embodiment Construction

[0017] The invention provides a method and device for rapid density measurement, which includes three parts: an upper weighing device, a host, and a lower weighing device. The part above the host platform is called the upper weighing device, and the part below the lower hook of the host is called the lower weighing device. figure 1 It is a schematic diagram of a measuring device used to quickly measure the density of solids.

[0018] The upper weighing device includes: glass windshield (1), weighing pan handle (2), weighing pan (3), lower pressure head (5), screw (13), nut (4), weighing object ( 6), the liquid medium used for weighing (7), the support cylinder (or support frame) of the weighing pan (8), the container (9) for the liquid medium, the weighing base (10), the container for the liquid medium Bracket (support) (11).

[0019] The glass windshield (1) surrounds the upper weighing device to prevent airflow from affecting the measurement results. The shape of the weighing ...

Abstract

The invention discloses a method and an apparatus for rapid measuring of density. The apparatus comprises a glass wind cap (1), a weighing tray handle (2), a weighing tray (3), a pressing down head (5),a screw (13), a nut (4), an object to be weighed (6), a measuring liquid medium (7), a support cylinder (a support frame) (8) for the weighing tray, a container (9) for holding the liquid medium, aweighing pedestal (10), a support (a bearer) ( 11) for the container holding the liquid medium, a mainframe (14), a weighing sensor (12), a support column (17), a lower hook (15), a lifting rope (16), a suspending weighing tray (20) for measuring, a liquid medium (21) for measuring, a container (18) for holding the liquid medium, etc. Compared to the prior art, the invention has the following advantages: measuring results are accurate and can be obtained rapidly; considerable manpower and material resources are saved; the method can be used for on-line rapid detection and has critical significance to improve and control product quality.

Description

Technical field [0001] The invention relates to a method and device for rapid density measurement, in particular to a measuring device for measuring the density of loose and porous solid objects. Background technique [0002] The density of an object is usually measured by Archimedes’ principle, that is, the weight of the object in the air is weighed, and the object is immersed in the liquid medium, and the weight of the object in the liquid medium is weighed. The density of the object is obtained by calculation. Here The liquid medium used is usually water or kerosene. This method is suitable for most objects, but it cannot be used to measure the density of loose and porous objects, such as refractory materials and powder molding blanks. This is because water or kerosene is infiltrating most objects. When the object is immersed in a liquid medium, water or kerosene will penetrate into the internal voids of the object, so the measured volume of the object is not accurate at all....
