Abstract
The utility model discloses a gravimetric method steam adsorbs cavity of appearance, including micro balance, outer cavity and interior cavity, micro balance sets up in the center of interior cavity, and the inner chamber position is the U -shaped in the internal and interior cavity of exocoel, and the top of cavity is connected at the top of outer cavity in the U -shaped, connects at internal interior cavity and the exocoel bodily form one -tenth airflow channel of exocoel, the heat preservation of outer cavity for having the heat preservation effect, the bottom center of outer cavity and the buffering net of lateral wall for ventilating and flowing that the top center was equipped with inlet port and exhaust hole, interior cavity respectively. The utility model discloses rational in infrastructure, the air current that gets into in the cavity is even, steady, and the data error that records is little, the degree of accuracy is high.
Description
Technical field
The utility model relates to adsorption plant field, is specifically related to a kind of cavity of gravimetric method vapor sorption instrument.
Background technology
Gravimetric method vapor sorption instrument be by gas under certain relative humidity by sample after the change of weight measure vapor sorption, faster than traditional dry method measurement, more save time.The laboratory of gravimetric method vapor sorption instrument product is all over the world widely used, and can be used for research and development department and Quality Control department determines solid material Problems existing in product structure, product stability, hydroscopicity, packaging and product development.
Gravimetric method vapor sorption instrument is placed on microbalance by testing sample, and steam is by sample, and microbalance can measure the mass change caused by vapor sorption.Existing gravimetric method vapor sorption instrument is the bottom inflow from cavity, gas is directly discharged from cavity top by after sample again, air-flow in the gravimetric method vapor sorption instrument of this structure directly passes through microbalance from below to up, air-flow is uneven, not steady, the data result error recorded by microbalance is large, and accuracy is not high.
Utility model content
The purpose of this utility model is to overcome the above-mentioned shortcoming existed in prior art, provides a kind of rational in infrastructure, enters the uniform stream in cavity, steadily, the cavity of the gravimetric method vapor sorption instrument that the data error recorded is little, accuracy is high.
To achieve these goals, the technical solution adopted in the utility model is as follows: a kind of cavity of gravimetric method vapor sorption instrument, comprise microbalance, outer chamber and inner chamber body, wherein: microbalance is arranged at the center of inner chamber body, inner chamber body is positioned at outer chamber and inner chamber body takes the shape of the letter U, the top of U-shaped inner chamber body is connected to the top of outer chamber, is connected to the inner chamber body in outer chamber and outer chamber formation gas channel; Outer chamber is the heat-insulation layer with insulation effect, and the bottom centre position of outer chamber and top center are respectively equipped with air admission hole and vent port, and the sidewall of inner chamber body is can the buffer subsystem of vent flow.
In the utility model, further, the bottom of inner chamber body is provided with heating element.
The beneficial effects of the utility model are: the sidewall of U-shaped inner chamber body is the buffer subsystem of vent flow and the gas channel that formed by inner chamber body and outer chamber can make to enter uniform stream in gravimetric method vapor sorption instrument, gently by microbalance, thus obtain the little and measurement data accurately of error; In addition, the heating element bottom inner chamber body can carry out preheating to the sample in microbalance.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the utility model, the accompanying drawing used in describing embodiment below and Reference numeral do simple introduction.
Fig. 1 is the structural representation of the utility model embodiment.
Description of reference numerals: 1-microbalance, 2-outer chamber, 3-inner chamber body, 4-gas channel, 5-air admission hole, 6-vent port, 7-buffer subsystem, 8-heating element.
Embodiment
In order to understand the utility model further, below in conjunction with the accompanying drawing in the utility model embodiment, the scheme in the utility model embodiment is clearly and completely described.
See Fig. 1, in the utility model embodiment, a kind of cavity of gravimetric method vapor sorption instrument, comprise microbalance 1, outer chamber 2 and inner chamber body 3, wherein: microbalance 1 is arranged at the center of inner chamber body 3, inner chamber body 3 is positioned at outer chamber 2 and inner chamber body 3 takes the shape of the letter U, and the top of U-shaped inner chamber body 3 is connected to the top of outer chamber 2, is connected to inner chamber body 3 in outer chamber 2 and outer chamber 2 forms gas channel 4; Outer chamber 2 is for having the heat-insulation layer of insulation effect, and the bottom centre position of outer chamber 2 and top center are respectively equipped with air admission hole 5 and vent port 6, and the sidewall of inner chamber body 3 is can the buffer subsystem 7 of vent flow; The bottom of inner chamber body 3 is provided with heating element 8.
When using the gravimetric method vapor sorption instrument of the utility model embodiment, air-flow enters from air admission hole 5, by the gas channel 4 formed by inner chamber body 3 and outer chamber 2, then enter inner chamber body 3 inside from buffer subsystem 7, air-flow is discharged from vent port 6 eventually through after microbalance 1.In the utility model embodiment, the air-flow entered in gravimetric method vapor sorption instrument cavity is comparatively even, mild, thus it is little to measure the data error obtained, and accuracy is high.
It should be pointed out that and be described above embodiment of the present utility model.But; the technician of art technology should be appreciated that; the utility model is not restricted to the described embodiments; what describe in above-described embodiment just illustrates principle of the present utility model; under the prerequisite not departing from the utility model scope, the utility model also has multiple changes and improvements, and these changes and improvements all fall within the scope of claimed the utility model.
Claims (2)
1. the cavity of a gravimetric method vapor sorption instrument, comprise microbalance, outer chamber and inner chamber body, it is characterized in that: described microbalance is arranged at the center of inner chamber body, described inner chamber body is positioned at described outer chamber and inner chamber body takes the shape of the letter U, the top of described inner chamber body is connected with the top of described outer chamber, and inner chamber body and outer chamber form gas channel; Described outer chamber is the heat-insulation layer with insulation effect, and the bottom centre position of described outer chamber and top center are respectively equipped with air admission hole and vent port, and the sidewall of described inner chamber body is can the buffer subsystem of vent flow.
