Description
Technical Field
[0001] The utility model relates to the technical field of smoke density testing, in particular to a smoke density testing device suitable for closed and semi-closed environment tube boxes. Background Art
[0002] Since the combustion behavior of flame retardant materials in fire is very complex, a single combustion test method cannot fully describe its combustion performance. Therefore, people try to evaluate the flame retardant properties of flame retardant materials more comprehensively from multiple aspects through the study of flame retardant material testing and characterization methods.
[0003] After the test of the existing smoke density test device is completed, because the material is placed in the test barrel for combustion during the test, and the heat generated by the combustion will be transferred to the test barrel, the personnel need to wait for the test barrel to cool down before pouring out the residue in the test barrel. If the residue is directly poured out by hand, the high-temperature test barrel will cause burns to the personnel's hands. When the existing smoke density test device is used, the burning material is often placed in a sealed environment for smoke density testing. However, only relying on a sealed environment for testing cannot fully test the flame retardant properties of the material. Therefore, it is necessary to test the smoke density of the material in all aspects. Therefore, a smoke density testing device suitable for closed and semi-closed environment tube boxes is proposed to solve the above problems. Utility Model Content

When it is necessary to clean the residue in the test barrel 12, the rotating rod 17 fixedly installed on the outside of the mounting sleeve 16 can be rotated, and the rotating rod 17 can drive the connecting column 10 to rotate. When the connecting column 10 rotates, the test barrel 12 will be driven to rotate, and then the residue in the test barrel 12 can be dumped into the collection box 21, and the residue in the test barrel 12 can be cleaned without manual touch of the test barrel 12. When the cleaning is completed, the rotating rod 17 can be rotated counterclockwise to reset the test barrel 12, and then semi-closed and fully open smoke density tests can be performed, and the smoke density data of the material can be accurately calculated after the closed test, semi-closed test and fully open test.
[0023] Specifically, the collecting component includes two inner walls on both sides of the through hole, each of which is provided with a slide groove 19, and a slider 20 is slidably installed in the two slide grooves 19. The two sliders 20 are fixedly connected to the same collecting box 21 on one side where they are close to each other, and a handle 22 is fixedly installed on one side of the collecting box 21. Through the provided collecting box 21, when the test barrel 12 is turned over to dump the residue inside, the residue can directly fall into the collecting box 21, which is convenient for subsequent unified processing. When cleaning, it is only necessary to pull the handle 22 to drive the sliders 20 fixedly installed on both sides of the collecting box 21 to move in the two slide grooves 19, and then the collecting box 21 will move out of the through hole, and the residue in the collecting box 21 can be processed.
[0024] Specifically, the adjustment component includes a sealing box 4 fixedly connected to the output end of the electric push rod 3, and the sealing box 4 is provided with two slots 5, and the two slots 5 are plugged with sealing plates 6, and the top sides of the two sealing plates 6 are fixedly installed with handles 7, and the two handles 7 are U-shaped, and the bottom side of the sealing box 4 faces the workbench 8 and is adapted to the workbench 8. Through the two sealing plates 6, when it is necessary to perform a semi-enclosed smoke density test on the material, the two sealing plates 6 are removed from the two slots 5 by pulling the two handles 7, and then the sealing box 4 will be in a semi-enclosed state, and then the material can be tested. Burning is carried out, and then the smoke density data in a semi-closed state can be obtained by the set smoke density tester 18, and the sealed box 4 is driven downward by the electric push rod 3. When the sealed box 4 is in contact with the workbench 8, the sealed box 4 will form a closed space, and then the burning material can obtain the smoke density data in a closed state. When a smoke density test in an unclosed state is required, the sealed box 4 is driven upward by the electric push rod 3, and the test barrel 12 will be in an open state.

The inner wall of the sealed box 4 contacts the outer side of the workbench 8 to form a sealed space, and then the igniter 14 is started through the control panel 23. The operation of the igniter 14 drives the ignition tube 15 to ignite the material in the test barrel 12, and then the material burns in the sealed space. The smoke density tester 18 set on one side of the mounting plate 9 can collect the smoke generated by the burning material in the sealed space, and then transmit the data to the control panel 23, so that the personnel can obtain the smoke density data of the closed space. When a semi-enclosed test is required, the sealed box 4 is driven upward by the electric push rod 3, and then the rotating rod 17 fixedly installed on the outer side of the rotating sleeve 16 can be driven by the rotating rod 17 to drive the connecting column 10 to rotate.

Then the igniter 14 is operated again to make the ignition tube 15 ignite the material placed in the test barrel 12. The smoke generated when the material burns will be collected by the smoke density tester 18, and then the smoke density tester 18 can transmit the smoke density data in the semi-closed state to the control panel 23, and if it is necessary to test the smoke density without sealing, it is only necessary to drive the sealing box 4 to move up by the electric push rod 3, and then the test barrel 12 will be in a fully open state, and then the burning material can obtain the fully open smoke density data. After the material has passed the closed test, the semi-closed test and the fully open test, the smoke density data of the material can be accurately calculated.
