Abstract
The utility model relates to an air extracting device, in particular to a vacuum degasser, which solves the problems in the prior art that the air is not extracted completely resulting in declinational measured value in the process of measuring magnetic iron ore mud. The air extracting device comprises a vacuum pump arranged on a base, an air extracting vessel, an air extracting tube communicated between the vacuum pump and the air extracting vessel and an air bleeder arranged on the air extracting vessel. The utility model has simple structure, low cost and shortened measuring time and is applicable to the true relative density measurement of material with high density in the metallic mineral class.
Description
Technical field
The utility model relates to a kind of air extractor, is specially a kind of vacuum outgas instrument.
Background technology
In ature of coal chemical examination, at measuring true relative density in the magnetite powder test method, but contain the gas of many absorption in the pore of magnetite powder, so when measuring material density, will bring bigger error.
Summary of the invention
The utility model is not in order to get rid of totally and to cause measured value problem devious that a kind of vacuum outgas instrument is provided owing to gas in the process that solves the mensuration magnetite powder that exists in the prior art.
The utility model is realized by following technical scheme, and a kind of vacuum outgas instrument comprises the vacuum pump that is installed on the base, the container of bleeding, and vacuum pump and bleed and be communicated with exhaust tube between the container is equipped with the venting valve on the container of bleeding.
Earlier determined sample is put in the container of bleeding when practical, the airtight then container of bleeding, send electricity to make vacuum pump work, vacuum pump makes the container of bleeding form negative pressure, the gas that adsorbs in the pore of magnetite powder is discharged, and calculate the true relative density of magnetite powder according to discharge with the quality of the water of volume.
Compared with prior art, the design that the utility model has adopted the vacuum pump and the container of bleeding to combine can make the environment that forms a relative vacuum in the container of bleeding, effect by negative pressure can remove a small amount of gas in the object, guarantee the accurate of experimental data, through data statistic analysis repeatedly, the result shows that the result who does not use this device to measure differs 0.32 than actual value, use this device back to conform to standard value, maximum error is no more than 0.02, the utility model is simple in structure, with low cost, minute is short, is applicable to the mensuration of the true relative density of the material that metalliferous mineral class density is bigger.

Embodiment
A kind of vacuum outgas instrument comprises the vacuum pump 1 that is installed on the base 5, the container 4 of bleeding, and vacuum pump 1 and bleed and be communicated with exhaust tube 2 between the container 4 is equipped with venting valve 6 on the container 4 of bleeding.Bleeding also is equipped with tensimeter 3 on the container and is used to observe pressure inside, and the container of bleeding is generally the glass transparent container, so that observe the state of inner material.The container 4 of bleeding can use exsiccator to make.
Bleed and to open venting valve 6 after finishing and make container 4 internal and external pressure balances of bleeding, so that open the container 4 of bleeding.
Claims (1)
1. a vacuum outgas instrument is characterized in that: comprise the vacuum pump (1) that is installed on the base (5), the container of bleeding (4), be communicated with exhaust tube (2) between vacuum pump (1) and the container of bleeding (4), venting valve (6) is installed on the container of bleeding (4).
