Description

Technical Field

[0001] This utility model relates to the field of flash point determination technology, and in particular to a fully automatic Cleveland open cup flash point tester. Background Technology

[0002] In the fields of petrochemicals and road engineering, the flash point and ignition point of asphalt are core indicators for evaluating its safe performance. The flash point determines the fire safety threshold during asphalt storage and transportation, while the ignition point relates to high-temperature safety control during asphalt pavement construction. Currently, the industry mainly uses a fully automated Cleveland open-cup flash point analyzer for testing. Its main working principle is to use a temperature sensor to adaptively adjust the heating power in real time to meet the testing heating rate, and to automatically analyze and capture the blue flame generated at the moment of flash explosion and the blue flame that can continue to burn for 5 seconds. The flash point and ignition point of the asphalt are recorded in real time by the temperature sensor.

[0003] However, existing fully automatic Cleveland open cup flash point testers still have certain shortcomings. For example, the open cup of traditional instruments rests on the operating table by its own weight without any limiting components, making it easy for the open cup to tip over. This can lead to the overflow of high-temperature asphalt, which can then adhere to the internal heating components of the instrument, causing corrosion and damage to the instrument parts and potentially triggering secondary combustion, threatening the safety of the operators. Secondly, additional fire extinguishing equipment is required to extinguish the burning asphalt, but if the fire extinguishing equipment is not nearby, it is difficult to extinguish the fire, posing a certain safety hazard.

A disc 16 is fixedly connected to the outer surface of the rotating shaft 15. A connecting post 17 is fixedly connected to the upper surface of the disc 16. A long strip plate 18 is rotatably connected to the outer surface of the connecting post 17. A fixed post 19 is rotatably connected to the inner surface of the long strip plate 18. A slider 20 is fixedly connected to the upper end of the fixed post 19. A clamping rod 21 is fixedly connected to the outer surface of the slider 20. A rubber block 22 is fixedly connected to the end of the clamping rod 21 away from the slider 20. An opening groove 23 is provided on the upper surface of the mounting plate 4.

The detailed connection methods are well-known in the art. The following mainly introduces the working principle and process, and will not describe the electrical control further.

[0030] Working principle: During operation, the Cleveland open cup 24 is placed in the opening groove 23. Then, the motor 14 is started, driving the rotating shaft 15 to rotate the disc 16. Under the hinge action of the connecting column 17, the long plate 18, the fixed column 19, and the slider 20, the four clamping rods 21 move towards each other, thereby fixing the Cleveland open cup 24 inside the opening groove 23 through the rubber block 22. This improves the stability of the Cleveland open cup 24 during testing, reducing the risk of shaking and enhancing operational safety. Then, the flashing... The ignition point tester 1 measures the flash ignition point of the asphalt inside the Cleveland open cup 24. After the test is completed, the ignition assembly is removed, and the L-shaped toothed block 10 is pushed down along the slide rod 7 inside the slide groove 6, and the spring 9 is compressed. This causes the L-shaped toothed block 10 to disengage from the gear 12, thereby causing the cover plate 13 to flip around the drive shaft 11 under the action of gravity and cover the Cleveland open cup 24, thus extinguishing the fire source generated by the asphalt inside the Cleveland open cup 24 and further improving operational safety.
