Abstract
The utility model discloses a combined type environmental exposure test cabin used for testing the content of the poison material of the architectural materials. The utility model is that a pressure equalizing cabin which is communicated with the test cabinet is positioned above the test cabinet of the inner of the cabin body and a circulating air duct which is communicated with the test cabinet through the return-air board is positioned down the test cabinet, and the circulating air duct is communicated with the pressure equalizing cabin through the crosswind path. A centrifugal fan which promotes the air circulation flowing is furnished in the circulating air duct, and the partition board between the pressure equalizing cabin and the test cabinet is equipped with honeycomb ducts disposed in cross which is vertical to the pressure equalizing cabin and is communicated with the pressure equalizing cabin and the test cabinet. Two test cabinets are between which is equipped with a movable partition board. The test cabinet not only can test two small units under testing alone, but also can test big volume unit under testing in together. The test cabinet can satisfy different requirements of the unit under testing and heighten the testing efficiency, the test cabinet guarantees the temperature uniform of the examples, and the repeatability of the test data is well.
Description
(1) technical field:
The utility model relates to a kind of proving installation, relates in particular to a kind of combined type environment test chamber that is used for material volatile quantities such as test architecture material formaldehyde and VOC.
(2) technical background:
Along with the raising of expanding economy and national life level, huge variation has taken place in human room and working environment.Building decoration artificial board and goods thereof are widely used, and China's artificial board is to adopt Lauxite to produce mostly, so contain poisonous and harmful substance in the sheet material, particularly contains a large amount of formaldehyde.Because of its formaldehyde emission has long process, after it was made furniture or is used for interior decoration, the formaldehyde in the sheet material still can constantly outwards distribute, and causes room air pollution, thereby the healthy of people worked the mischief.Thereby there is strict requirement in government department to contained formaldehyde amount in the artificial building board, the device that can develop contained formaldehyde amount in the artificial building board of accurate measurement has become the task of top priority, in development in 2000 " indoor environment testing cabinet for building engineering and combined type are surveyed the formula cabin ", its number of patent application is 02115731.6 to the applicant.Find through repeated detection is on probation, directly enter in the test chamber after the equal ballasting in air enters environmental test chamber by equal plate hole, this kind intake method is easy to cause following deficiency: promptly 1, in a single day air-flow enter test chamber content malleable direction, thereby air-flow can not evenly move forward in test chamber, and make in the test chamber atmospheric density or sample non-uniform temperature or in the cabin, form eddy current, and then influence test data, make that the test data error is big, poor repeatability; 2, test airflow is in the test indoor circulation, and measured piece is between the circulating current of the left and right sides, thereby test airflow is easy to generate non-uniform phenomenon when turning round in the operating room, influences test data.
(3) summary of the invention: the uneven phenomenon of indoor temperature that exists when the building materials objectionable impurities being tested in order to solve environmental test chamber, the test data error is big, the shortcoming of poor repeatability, and the utility model provides a kind of test data good reproducibility, error is little, accuracy is high, the environment of combined type flexibly test chamber easy to use.The technical solution of the utility model realizes in the following manner:
A kind of combined type environment test chamber that is used for building materials noxious material content measuring, it mainly comprises and wind circulating system, the pure air disposal system, air changes wind system, the aerial temperature and humidity regulating system, the cabin body that electrical automation control system and air sampling analytic system connect, be provided with test cabinet in the body of cabin, wherein the test cabinet top is the equal ballasting that is communicated with test cabinet, the circulation air path of below for being communicated with test cabinet by the return air plate, circulation air path is communicated with equal ballasting by test cabinet crosswind road, the centrifugal blower that promotes that air circulation flows is housed in circulation air path, equal all pressing between ballasting and the test cabinet be provided with on the dividing plate arrange in length and breadth with all press divider upright, the mozzle that communicates with equal ballasting and test cabinet is to guarantee to enter the evenly operation forward of air-flow in the test cabinet, test cabinet is two, two test cabinets) between be provided with active clapboard.
The crosswind road is located at test cabinet one side.
Three of centrifugal blowers are one group, are located at respectively in the two test cabinets crosswind road separately.
Good effect of the present utility model is: 1, test cabinet is two and is combined into one, and two test cabinets both can be tested separately two different measured pieces, can test jointly a bulky measured piece again, thereby it is convenient, flexibly, satisfy the requirement of different measured pieces, improve testing efficiency; 2, because the setting of mozzle, make air-flow at first put in order and become air-flow vertical, that evenly move forward by mozzle, guarantee that test job indoor current density or sample temperature are even, avoid air-flow in the cabin, to form eddy current, make that the test data error is little, good reproducibility, the setting of axial fan and circulation air path further guarantee evenly flowing of air-flow.
(4) description of drawings:
Fig. 1 is two main TV structure principle schematic that test cabinet is combined into one in the utility model.
Fig. 2 is the side-looking structural principle synoptic diagram of Fig. 1.
Fig. 3 is single test chamber structural principle synoptic diagram.
(5) embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing: by Fig. 1, Fig. 2, Fig. 3 as can be seen, this test chamber mainly comprises and wind circulating system, the pure air disposal system, air changes wind system, the aerial temperature and humidity regulating system, the cabin body that electrical automation control system and air sampling analytic system connect, be provided with test cabinet 7 in the body of cabin, its test cabinet top is the equal ballasting 5 that is communicated with test cabinet, the circulation air path 2 of below for being communicated with test cabinet by the return air plate, circulation air path is communicated with equal ballasting by the crosswind road 8 of test cabinet one side, test cabinet is two, is provided with active clapboard 6 between two test cabinets; 1 three of centrifugal blowers are one group, are located at respectively in two test cabinets (3,7) the crosswind road separately; All pressing between equal ballastings and two test cabinets is provided with evenly moving forward with the air-flow that assurance enters in the test cabinet with the mozzle 4 of all pressing divider upright, communicate with all ballasting and test cabinet of arranging in length and breadth on the dividing plate.
When the test block volume hour, only starting an operating room gets final product, the air of coming in by the air dilution air plant that is communicated with circulation air path is under the effect of centrifugal blower, air walks to equal ballasting by circulation air path, forms air-flow stably then, by the mozzle effect, entering in the test cabinet that measuring puts specimen of vertical parallel, when air-flow walks to the test cabinet bottom,, suck the air channel once more by centrifugal blower by the return air board pore.
After the work indoor air flow circulation regular hour, take a sample, detect its content of formaldehyde with pick-up unit by the air outlet that is communicated with circulation air path.
Big when measured piece, when a test cabinet can hold any more, the dividing plate between two test cabinets is extracted out, make two test cabinets be combined as a test cabinet and finish test jointly.
