Description
Technical field
The utility model relates to a kind of constant temperature humidity chamber.
Background technology
According to the testing requirement of country to PM2.5, high-precision electronic balance (100,000/balance) need be placed in the environment of constant temperature and humidity, the concentration of PM2.5 being tested, for ensureing the requirement of measuring accuracy and the degree of accuracy, an amplitude need be provided little, vibration frequency is low, noise is little, and the testing equipment that operating personnel also can come in and go out, this equipment is relatively airtight, humiture is stablized, and fully can meet the requirement of " GB10586-2006 moisture-heat test-box technical conditions ".Current cryogenic thermostat constant moisture test case vibrations are comparatively large, so very large to Influence on test result, cause measurement result inaccurate.
Utility model content
Because the above-mentioned defect of prior art, it is little that technical problem to be solved in the utility model is to provide a kind of vibrations, and good seal performance, measures constant temperature humidity chamber accurately.
For achieving the above object, the utility model provides a kind of constant temperature humidity chamber, comprise test box body, Compressor Group, blower fan is provided with in air channel between the box liner of described chamber and cabinet shell, air channel comprises heating system, refrigeration system, humidification system and electrical apparatus control system, it is characterized in that: described Compressor Group and test box body adopt split to arrange, described box liner is provided with a square hole, separating plate is movably set with in described square hole, sealing strip is provided with between described separating plate and described casing, described test box body bottom welding has channel-section steel, some layers of rubber are equipped with between described separating plate and described channel-section steel, described separating plate lower surface contacts with rubber, upper surface is concordant with box liner.
Further, described separating plate side is provided with upper strata sealing strip and lower floor's sealing strip, and described sealing strip is silica gel adhesive tape.
Further, described box liner comprises inner bag upper plate, inner bag lower plate and inner bag side plate, and the inner bag side plate of described fixing blower fan is connected among the buckling groove of inner bag upper plate and inner bag lower plate, is provided with yielding rubber in described buckling groove.
The beneficial effects of the utility model are: the utility model adopts test box body and compressor to adopt body separate mode, effectively reduce the vibrations of test box body, separating plate and the test box body structure also for being separated simultaneously, so the vibrations of test box body are less on measurement result impact.

In figure: 1, test box body; 2, channel-section steel; 3, blower fan; 4, silica gel adhesive tape; 5, separating plate; 6, inner bag lower plate; 7, inner bag upper plate; 8, inner bag side plate; 81, yielding rubber; 82, Access Division.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail:
See a kind of constant temperature humidity chamber shown in Fig. 1 to Fig. 3, comprise test box body 1, Compressor Group, blower fan 3 is provided with in air channel between the box liner of described chamber and cabinet shell, air channel comprises heating system, refrigeration system, humidification system and electrical apparatus control system, described Compressor Group and test box body 1 adopt split to arrange, described box liner is provided with a square hole, separating plate 5 is movably set with in described square hole, sealing strip is provided with between described separating plate 5 and described casing, described test box body 1 bottom welding has channel-section steel 2, some layers of rubber are equipped with between described separating plate 5 and described channel-section steel 2, described separating plate 5 lower surface contacts with rubber, upper surface is concordant with box liner.
The utility model when in use process is as follows, chamber is placed on ground, separating plate 5 is placed among the square hole in test box body 1, change into: balance is shelved platform (being generally marble desk) and be placed on separating plate 5, again precision balance is put on desktop, at the trial PM2.5 sample is put into balance, shut the chamber door (chamber door is not shown) of chamber, open chamber power supply, blower fan 3 starts to rotate, the gas needing to detect is sucked among air channel and circulates, through heating system, refrigeration system, humidification systems etc. allow it keep constant temperature and humidity conditions, owing to being provided with sealing strip between separating plate 5 and casing, so the gas in chamber can not spill into outside, the gas of outside also can not enter among chamber, so can not have an impact to result, because separating plate 5 is separated with test box body 1, so the vibrations of blower fan 3 affect less on separating plate 5.Test box body 1 bottom welding has channel-section steel 2, is equipped with rubber between separating plate 5 and described channel-section steel 2, effectively can alleviate the vibrations being passed to test box body 1 time compressor shakes by ground.
Further, described separating plate 5 side is provided with upper strata sealing strip and lower floor's sealing strip, and described sealing strip is silica gel adhesive tape 4.Silica gel adhesive tape 4 is soft, and has good ductility, so can get good hermetic separation plate 5 and test box body 1.
It is preferred that described box liner comprises inner bag upper plate 7, inner bag lower plate 6 and inner bag side plate 8, the inner bag side plate 8 of described fixing blower fan 3 is connected among the buckling groove of inner bag upper plate 7 and inner bag lower plate 6, is provided with yielding rubber 81 in described buckling groove.Impact on measurement result is rotated in order to reduce blower fan 3 further, described inner bag side plate 8 is connected with inner bag lower plate 6 with inner bag upper plate 7 by Access Division 82, at inner bag upper plate 7 and inner bag lower plate 6, inner bag side plate 8 access section is provided with buckling groove, in described buckling groove, is provided with yielding rubber 81.
More than describe preferred embodiment of the present utility model in detail.Should be appreciated that those of ordinary skill in the art just can make many modifications and variations according to design of the present utility model without the need to creative work.Therefore, all technical staff in the art according to design of the present utility model on the basis of existing technology by the available technical scheme of logical analysis, reasoning, or a limited experiment, all should by the determined protection domain of claims.
