This structure is common in the existing exhaust filtering structure, and the principle thereof will not be described in detail herein.

[0034] Working principle:

[0035] In use, an operator first fixes a test sample (300 mm x 89 mm) on the mounting block 9 by the four clamping strips 10, which can be fixed by bolts or external clamps. The tenon at the top of the mounting block 9 is connected to the mortise 11 on the mounting plate 4, so as to ensure that the test sample is vertically hung. After being sequentially hung, the driving rod 2 is driven by the driving motor 3 through the speed reducer 42 to rotate at a low speed (< 5° / s), so that the test sample sequentially enters the test station close to the ignition device 15. During testing, the driving rod 2 stops rotating, the test motor 13 drives the first screw rod 18 to move horizontally to ignite the ignition device, and simultaneously drives the second screw rod 20 to move the positioning rod 17 into the positioning groove 22 of the mounting block 9 through belt transmission, so as to lock the center position of the bottom edge of the test sample. The ignition device is supplied with gas (propane or methane), and the height of the flame is stabilized to (40 ± 2) mm. Simultaneously, before the test sample enters the test station, the driving rod 2 rotates to trigger the bevel gear set, drives the cam 34 to lift the wind shield 7 to close the ventilation hole 6 of the detection box 1, so as to isolate external airflow. At the same time, the lifting gear 27 is positively rotated through the half gear 28, and the lifting sleeve 26 drives the lifting rod 25 and the supporting disc 5 to ascend and approach the test sample.

[0036] After the ignition source is removed, the automatic timer records the afterburning time and smoldering time. If the test sample contains molten fibers, the absorbent cotton on the supporting disc 5 is located below the test sample, which can effectively monitor whether the molten droplets ignite. After waiting for the combustion to end, the test sample is sequentially tested by rotating the driving rod 2. After all the tests are completed, the test sample is manually taken out, and the damaged length is measured according to the hanging detection standard.

[0037] During testing, the wind shield 7 closes the ventilation hole 6; after the test is completed, the cam 34 is reset, the spring 32 pulls down the wind shield 7 to open the natural ventilation. The exhaust gas is forcibly discharged by the fan 39 at the top. The driving rod 2 continuously rotates to switch the test sample, and the supporting disc 5 is driven to descend and reset through the half internal gear 29, so as to realize continuous detection of multiple test samples.

[0038] Finally, it is to be explained that the above embodiments are only used to illustrate the technical solutions of the present application but not to limit the present application. Although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or equivalently replaced without departing from the purpose and scope of the present application, and all of them should be covered in the scope of the claims of the present application.
