Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] like Figures 1 to 9 As shown, the present invention provides a flame retardant performance detection device for asphalt flame retardant, comprising a fixed shell 1, a fixed tube 8 is fixedly installed on one side of the fixed shell 1, a fixed mounting plate 9 is fixedly installed on the side of the fixed shell 1 away from the fixed tube 8, and further comprising:

[0035] A driving assembly 4, which is arranged on a side of the fixed housing 1 away from the fixed pipe 8;

[0036] An absorption component 5, the absorption component 5 is fixedly mounted on one side of a fixed mounting plate 9;

[0037] The driving assembly 4 includes a driving motor 401, a worm 402 is fixedly mounted on the output end of the driving motor 401, a gear 403 is fixedly mounted on the top of the worm 402, and a first L-shaped toothed plate 404 and a second L-shaped toothed plate 405 are respectively meshed and connected on both sides of the gear 403;

[0038] The absorption assembly 5 comprises a worm gear 501 , a mounting shaft 502 is fixedly mounted in the middle of the worm gear 501 , and an eccentric block 503 is fixedly connected to the outer wall of the mounting shaft 502 .

[0039] The above scheme is adopted: through the cooperation of the driving component 4 and the absorption component 5, the driving motor 401 rotates to drive the worm 402 and the gear 403 to rotate. When rotating clockwise, the first L-shaped tooth plate 404 and the second L-shaped tooth plate 405 drive the two groups of connecting blocks 406 to move toward each other, and the two groups of connecting blocks 406 resist the rectangular block 407, so that the rectangular block 407 moves to both sides, so that the harmful gas released by the combustion of the asphalt sample mixed with flame retardant flows into the connecting pipe unit 504 through the through hole opened in the fixed mounting plate 9, and the eccentric block 503 does not resist the rectangular plate 506, so that the second spring 505 drives the rectangular plate 506 and the connecting pipe unit 504 to reset, so that the connecting pipe unit 504 transfers the harmful gas released by the combustion of the asphalt sample mixed with flame retardant in the inner cavity of the fixed shell 1 to the inner cavity of the gas cleaning box 6. When rotating counterclockwise, the gear 403 drives the first L-shaped tooth plate 404 and the second L-shaped tooth plate 405 to move the two groups of connecting blocks 406 to move toward each other. The two groups of connecting blocks 406 resist the rectangular block 407, so that the rectangular block 407 moves to both sides, so that the harmful gas released by the combustion of the asphalt sample mixed with flame retardant in the inner cavity of the fixed shell 1 flows into the inner cavity of the gas cleaning box 6. The plate 404 and the second L-shaped toothed plate 405 move in opposite directions, so that the first L-shaped toothed plate 404 and the second L-shaped toothed plate 405 drive the two connecting blocks 406 to release the conflict with the rectangular block 407, so that the first spring 408 drives the rectangular block 407 to reset, and blocks the through hole on the surface of the fixed mounting plate 9, to prevent the worm 402 from driving the worm wheel 501 to rotate, and the worm wheel 501 drives the eccentric block 503 to rotate. When the eccentric block 503 conflicts with the rectangular plate 506, the connecting pipe unit 504 and the second spring 505 contract, and the connecting pipe unit 504 brings the gas in the gas cleaning box 6 back to the inner cavity of the fixed shell 1 again, so as to collect the harmful gases released during combustion, and the gases will not cause harm to the environment and the body of the inspector. The design of the fixed pipe 8 makes it possible to continuously replenish air in the fixed shell 1, so that there is enough air supply for asphalt combustion.

[0041] The above scheme is adopted: through the cooperation of the connecting block 406 and the rectangular block 407, when rotating counterclockwise, the gear 403 drives the first L-shaped toothed plate 404 and the second L-shaped toothed plate 405 to move away from each other, so that the first L-shaped toothed plate 404 and the second L-shaped toothed plate 405 drive the two connecting blocks 406 to release the conflict with the rectangular block 407, so that the first spring 408 drives the rectangular block 407 to reset, and blocks the through hole on the surface of the fixed mounting plate 9, so as to prevent the worm 402 from driving the worm wheel 501 to rotate, and the worm wheel 501 drives the eccentric block 503 to rotate. When the eccentric block 503 conflicts with the rectangular plate 506, the connecting pipe unit 504 and the second spring 505 are contracted. The connecting pipe unit 504 brings the gas in the gas cleaning box 6 back to the inner cavity of the fixed shell 1 again. The design of the sliding groove of the fixed mounting plate 9 and the slider of the rectangular block 407 allows the rectangular block 407 to limit the rectangular block 407 when moving, so that the rectangular block 407 can be more easily moved when moving. Stable, through the design of the connecting tube unit 504 and the rectangular plate 506, the harmful gas released by the combustion of the asphalt sample mixed with flame retardant flows into the connecting tube unit 504 through the through hole opened in the fixed mounting plate 9, and the eccentric block 503 does not conflict with the rectangular plate 506, so that the second spring 505 drives the rectangular plate 506 and the connecting tube unit 504 to reset, so that the connecting tube unit 504 can fix the inner cavity of the shell 1. The harmful gas released by the combustion of the asphalt sample mixed with flame retardant is sent to the inner cavity of the gas cleaning box 6, and the fixed mounting plate 9 is elastically connected to the rectangular plate 506 through the second spring 505, so that when it rotates counterclockwise, it is prevented that the worm 402 drives the worm wheel 501 to rotate, and the worm wheel 501 drives the eccentric block 503 to rotate. When the eccentric block 503 conflicts with the rectangular plate 506, the connecting tube unit 504 and the second spring 505 are contracted, and the connecting tube unit 504 brings the gas in the gas cleaning box 6 back to the inner cavity of the fixed shell 1 again.

[0042] like Figure 1 , Figure 7 and Fig. 9 As shown, the connecting pipe unit 504 is composed of a bellows and a straight pipe, the bellows is fixedly connected to the fixed mounting plate 9, and a through hole is opened on the surface of the fixed mounting plate 9 to communicate with the connecting pipe unit 504, a U-shaped fixing frame is provided on the outer wall of the mounting shaft 502, and is movably connected to the mounting shaft 502, the fixed mounting plate 9 is fixedly connected to the U-shaped fixing frame, a switch door is provided on the surface of the fixed shell 1, and a visual window is provided on the surface of the switch door.

[0043] The above scheme is adopted: through the design of the connecting pipe unit 504, the design of the bellows and the straight pipe, when the bellows is expanded, the harmful gas released by the combustion of asphalt in the inner cavity of the fixed shell 1 can be collected to avoid gas pollution to the air and harm to the body of the inspector. The through hole of the fixed mounting plate 9 is connected to the bellows, so that the harmful gas released by the combustion of asphalt enters the bellows through the through hole and finally reaches the gas cleaning box 6 to collect the harmful gas released by the combustion of asphalt. Through the design of the mounting shaft 502, the U-shaped fixing frame on the outer wall of the mounting shaft 502 is fixedly connected to the fixed mounting plate 9, so that the mounting shaft 502 is limited, making the mounting shaft 502 more stable when moving. The design of the visual window of the opening and closing door of the fixed shell 1 makes it possible to observe the combustion of the asphalt at all times, so as to better detect and analyze it.

[0044] like Figure 2 , Figure 5 and Figure 6 As shown, the worm 402 is meshedly connected with the worm wheel 501, the bottom of the worm 402 is movably connected with the fixed shell 1, the outer wall of the drive motor 401 is provided with a fixing frame, and is fixedly connected with the fixed shell 1, the bottoms of the first L-shaped tooth plate 404 and the second L-shaped tooth plate 405 are provided with limiting grooves, the top of the fixed shell 1 is provided with a limiting block, and is movably connected with the limiting grooves at the bottoms of the first L-shaped tooth plate 404 and the second L-shaped tooth plate 405, the rectangular block 407 is an inclined surface near the connecting block 406, and the connecting block 406 is movably connected with the fixed shell 1.

[0045] The above scheme is adopted: through the design of the worm 402 and the worm wheel 501, the worm 402 and the worm wheel 501 are meshed and connected, so that when the worm 402 drives the worm wheel 501 to rotate, the worm wheel 501 drives the eccentric block 503 to rotate, and when the eccentric block 503 conflicts with the rectangular plate 506, the connecting pipe unit 504 and the second spring 505 are contracted. The connecting pipe unit 504 brings the gas in the gas cleaning box 6 back to the inner cavity of the fixed shell 1 again, and the worm 402 is movably connected to the fixed shell 1, so that the worm 402 is limited, making the worm 402 more stable when rotating. The design of the fixing frame fixes the driving motor 401, thereby making the device run stably, and the first L-shaped tooth plate 404 and the second L-shaped tooth plate 404 and the second L-shaped tooth plate 405 are used. The design of the tooth plate 405, the design of the bottom limiting grooves of the first L-shaped tooth plate 404 and the second L-shaped tooth plate 405 and the top limiting block of the fixed shell 1, enable the limiting grooves and the limiting blocks to cooperate with each other to limit the first L-shaped tooth plate 404 and the second L-shaped tooth plate 405 when the gear 403 drives the first L-shaped tooth plate 404 and the second L-shaped tooth plate 405 to move, so that the first L-shaped tooth plate 404 and the second L-shaped tooth plate 405 are more stable when moving. The design of the rectangular block 407 and the design of the inclined surface of the rectangular block 407 make it more convenient for the connecting block 406 to contact the rectangular block 407. The connecting block 406 is movably connected to the fixed shell 1, so that the fixed shell 1 limits the connecting block 406 when the connecting block 406 moves.

[0046] like Figure 1 , Figure 2 and Figure 4 As shown, the inner cavity of the fixed shell 1 is movably connected with the ignition module 2 and the clamping module 3 in sequence, and the side of the fixed shell 1 close to the driving component 4 is movably connected with the connecting shaft unit 7, and a handle is provided on the top of the connecting shaft unit 7. The upper and lower ends of the outer wall of the connecting shaft unit 7 are provided with threads, and the thread directions are opposite, and the ignition module 2 and the clamping module 3 are threadedly connected with the connecting shaft unit 7.

[0047] The above scheme is adopted: through the design of the ignition module 2 and the clamping module 3, the clamping parts on the surface of the clamping module 3 fix the asphalt sample mixed with the flame retardant, and the handle on the top of the connecting shaft unit 7 is rotated. The design of the handle makes it more convenient to rotate the connecting shaft unit 7, so that the ignition module 2 and the clamping module 3 move toward each other, open the ignition module 2, so that the ignition module 2 ignites the clamping module 3, and then rotate the connecting shaft unit 7 again, so that the ignition module 2 and the clamping module 3 move away from each other, avoiding the risk of the inspector scalding himself when igniting the asphalt sample mixed with the flame retardant. Through the design of the connecting shaft unit 7, the upper and lower ends of the connecting shaft unit 7 are provided with threads and the threads are in opposite directions, so that when the connecting shaft unit 7 is rotated, the connecting shaft unit 7 drives the ignition module 2 and the clamping module 3 to move toward or away from each other, thereby avoiding the risk of the inspector scalding himself when igniting the asphalt sample mixed with the flame retardant.

[0048] The working principle and use process of the present invention:

[0049] When in use, place the asphalt sample mixed with flame retardant on the surface of the clamping module 3, fix the asphalt sample mixed with flame retardant by the clamping piece on the surface of the clamping module 3, then rotate the connecting shaft unit 7, rotate the handle on the top of the connecting shaft unit 7, so that the ignition module 2 and the clamping module 3 move towards each other, open the ignition module 2, so that the ignition module 2 ignites the clamping module 3, and then rotate the connecting shaft unit 7 again, so that the ignition module 2 and the clamping module 3 move away from each other, so as to avoid the risk of burns to the inspector when igniting the asphalt sample mixed with flame retardant;

[0050] Start the driving motor 401, and the driving motor 401 rotates to drive the worm 402 and the gear 403 to rotate. When rotating clockwise, the gear 403 drives the first L-shaped tooth plate 404 and the second L-shaped tooth plate 405 to move toward each other, so that the first L-shaped tooth plate 404 and the second L-shaped tooth plate 405 drive the two groups of connecting blocks 406 to move toward each other, and the two groups of connecting blocks 406 resist the rectangular block 407, so that the rectangular block 407 moves to both sides, so that the harmful gas released by the combustion of the asphalt sample mixed with flame retardant is detected to flow into the connecting pipe unit 504 through the through hole opened in the fixed mounting plate 9. At this time, the eccentric block 503 does not resist the rectangular plate 506, so that the second spring 505 drives the rectangular plate 506 and the connecting pipe unit 504 to reset, so that the connecting pipe unit 504 can fix the harmful gas released by the combustion of the asphalt sample mixed with flame retardant in the inner cavity of the shell 1 to the gas When the inner cavity of the cleaning box 6 rotates counterclockwise, the gear 403 drives the first L-shaped tooth plate 404 and the second L-shaped tooth plate 405 to move oppositely, so that the first L-shaped tooth plate 404 and the second L-shaped tooth plate 405 drive the two connecting blocks 406 to release the conflict with the rectangular block 407, so that the first spring 408 drives the rectangular block 407 to reset, and blocks the through hole on the surface of the fixed mounting plate 9, to prevent the worm 402 from driving the worm wheel 501 to rotate, and the worm wheel 501 drives the eccentric block 503 to rotate. When the eccentric block 503 conflicts with the rectangular plate 506, the connecting pipe unit 504 and the second spring 505 contract, and the connecting pipe unit 504 brings the gas in the gas cleaning box 6 back to the inner cavity of the fixed shell 1 again. After the detection is completed, the harmful gas in the gas cleaning box 6 is processed, so that the harmful gas released during combustion will not cause harm to the environment and the body of the detection personnel.
