Description

Technical Field

[0001] The present invention relates to the technical field of oil product detection, and in particular to an online oil product detection device. Background Art

[0002] In the actual oil manufacturing process, as the production line processes oil products, workers are required to regularly sample the oil for testing. The flash point of oil products such as heavy oil directly affects their safety. The principle of oil flash point testing is based on the critical point detection of volatile vapor concentration. By precisely controlling the heating rate and ignition timing, the lowest temperature at which the combustible mixture flashes instantly when encountering an open flame is captured. When conducting oil testing, the current online oil detection device will generate a large amount of vapor as the oil pot heats up before the ignition test. While affecting the health of the workers, the accumulated vapor is likely to interfere with the actual flash point test accuracy. It is not convenient to automatically control the prevention of vapor evaporation during non-testing, and it is also not convenient to limit and remind workers to preheat before conducting heavy oil testing. Pouring directly into the oil pot is likely to generate bubbles due to excessive viscosity, affecting the oil level control accuracy and heating efficiency. It is also not convenient to quickly overflow and adjust the oil level standard value. The accuracy deviation of the poured oil level by manual visual observation is large and the flexibility is poor.

[0017] The use of an isolation mesh plate can utilize its own mesh structure, which has a limited diameter and can prevent staff from directly putting heavy oil that has not been heated to reduce viscosity into the oil pot.

This reminds staff to heat it first to assist in improving fluidity. At the same time, this structure uses a buoyancy detection component to remind staff in real time that the oil level is dropping, and the prompt light can be used for prompting. This is especially true for the flash point detection of heavy oil. After the heavy oil is filled, bubbles are likely to be generated inside, affecting the oil level accuracy.

The flash point control part 3 can be used to cooperate with the suction mounting ring 101 to automatically control the suction of the vapor evaporated by the heated oil product, which can effectively improve the safety of the actual flash point test. It can be controlled so that only when the ignition rod passes through the oil pot 104 during the flash point test, the oil pot 104 can normally produce vapor for flash point test, and observe the ignition situation. It can avoid that a large amount of vapor generated when the oil pot 104 is heated before the flash point is reached will be diffused in the flash point tester, causing pollution and easily causing safety hazards such as explosion. It can be more suitable for different oil product testing work, and can test both low flash point and high flash point oils. The control of this structure is simple, which ensures a reasonable range of oil product vapor volume. At the same time, it can ensure the vapor temperature when the ignition test is required. The characteristic that the ignition rod needs to swing to realize automatic control, which improves the comfort of the staff. As the heating wire in the flash point tester heats the oil in the oil pot 104, the process of pumping The suction fan connected to the air pipe 105 is kept powered on to extract air, and the suction installation ring 101 cooperates with the suction hole 1041 to suck the steam generated during the flash point test working interval and before the test. The suction pipe 105 is led out of the room. As the ignition rod of the flash point tester swings, the flame head at its end passes through the oil pot 104. At this time, the ignition rod of the flash point tester first passes through the inclined plate 3021. Using the inclined surface structure of the inclined plate 3021, when it slides over the inclined plate 3021, it presses down the lower pressure plate 302, compressing the lower pressure spring Spring 202, at which point the lifting power board 303 is driven downward and separated from the power connection block 106, and the suction fan connected to the exhaust pipe 105 is de-energized, stopping the absorption of oil vapor, and the oil can evaporate upward. The flash point tester's ignition rod needs time to move during its swing, ensuring that the test oil vapor has time to diffuse upward to above the height of the flame head. This process repeats itself, and as the oil temperature rises, the test is performed every few degrees until the oil vapor is observed to ignite. At this point, the oil temperature is the flash point temperature.

[0023] Among them, the limit control part 4 includes: a positioning column 401 and a positioning bolt 402, the positioning column 401 is inserted into the socket provided on the suction mounting ring 101; the positioning bolt 402 is inserted on the positioning column 401; the positioning bolt 402 is threadedly connected to the flash point tester table, and the positioning column 401 is retained on the flash point tester; the overflow part 5 includes: an overflow collection shell 501, the overflow collection shell 501 is fixedly sleeved on the outside of the suction mounting ring 101; an opening is provided on the inside of the overflow collection shell 501; the opening on the inside of the overflow collection shell 501 is connected to the overflow hole 1042; the overflow collection shell 501 is used to prevent the oil level from being too high; the overflow part 5 also includes: an overflow hose 502, the overflow hose 502 is fixedly mounted on the overflow collection shell 501; the overflow hose 502 It is a hose; the overflow hose 502 is used to drain excess oil; the overflow collection shell 501 is placed on the flash point tester table, and the limit control part 4 is used to facilitate the positioning of the detection installation part 1, which improves the stability during the test. It has a simple structure and can prevent the oil pot 104 from rotating at will. The overflow part 5 is used to facilitate the staff to control the oil level, and the oil can be added normally. The excess oil can be directly overflowed and discharged, which can effectively ensure the operational flexibility. No manual visual observation is required, the oil level is accurate, and the volume of the vapor space above the oil product meets the standard, avoiding the flash point value from deviating from the actual level, supporting data credibility, and reducing the defective product rate. The overflow hose 502 can be collected in an external oil collection tank for collection. The staff can operate it simply and conveniently, and there is no need to accurately observe the scale with the naked eye.

[0024] Example 2, based on Example 1, the buoyancy detection member 6 includes: an isolation mesh plate 601 and a float 602, the isolation mesh plate 601 is slidably sleeved inside the oil pot 104; the isolation mesh plate 601 is located above the raised ring inside the oil pot 104; the float 602 is fixedly installed at the bottom of the isolation mesh plate 601; the float 602 is a hollow structure; the isolation mesh plate 601 is provided with mesh holes; the isolation mesh plate 601 is used to limit the viscosity of the oil; the float 602 is used to float on the oil surface; the buoyancy detection member 6 also includes: a ceramic column 603 and a mobile electric ring 604, the isolation mesh plate 601 is fixed A circle of ceramic columns 603 is installed; a movable electric coil 604 is fixedly installed on the circle of ceramic columns 603, and the movable electric coil 604 is located above the overflow collection shell 501; the movable electric coil 604 is located inside the oil pot 104; the buoyancy detection part 6 also includes: a fixed electric coil 605 and a plastic ring 606, there are two fixed electric coils 605, the two fixed electric coils 605 are fixedly installed on the top of the oil pot 104; the two fixed electric coils 605 are insulated; the two fixed electric coils 605 are located above the movable electric coil 605; the two fixed electric coils 605 are fixedly installed inside Equipped with a plastic ring 606; the mobile power ring 604 is located outside the plastic ring 606; the two fixed power rings 605 and the warning light 103 are connected in series with the power supply. The isolation mesh plate 601 can utilize its own mesh structure, which has a limited diameter, and can limit the staff from directly putting the heavy oil that has not been heated to reduce the viscosity directly into the oil pot 104. Because the unheated heavy oil has poor fluidity and is difficult to quickly pass through the isolation mesh plate 601, it will limit the detection efficiency, thereby prompting the staff to heat it first to assist in improving fluidity. At the same time, this structure uses the buoyancy detection member 6 to real-time detect the heavy oil. The staff can be reminded of the oil level drop by the warning light 103, especially for the flash point test of heavy oil. After the heavy oil is filled, bubbles are easily generated inside. As the flash point test is performed during heating, when the bubbles float up, the oil level drops or the oil itself is not added in place, a prompt can be given in time, so that the staff can replenish the oil in time. The operation is simple and convenient. Once the oil level is too low, the float ring 602 will still float on the oil surface, but the height will drop. The two fixed contact rings 605 are no longer in contact with the movable contact ring 604, and the warning light 103 can provide a prompt.

[0025] The working principle of this embodiment is as follows: First, the preheated heavy oil is poured into the oil pot 104. At this time, with the buoyancy of the oil, the floating ring 602 is controlled to float up and drive the mobile contact ring 604 to move up and fit into the two fixed contact rings 605. At this time, the two fixed contact rings 605 are connected by the conductor of the mobile contact ring 604, and the warning light 103 lights up to indicate that the oil level is too low. At this time, the floating ring 602 will still float on the oil surface, but the height will drop. The two fixed contact rings 605 are no longer connected by the mobile contact ring 604, and the warning light 103 can be turned off to indicate that the oil sampled on the production line is directly poured into the oil pot 104. The oil level inside the oil pot 104 rises above the oil level. When the oil is discharged from the overflow hole 1042, the oil is collected by the overflow collecting shell 501 and then discharged from the overflow hose 502. The overflow hose 502 can be collected by the oil collecting tank. The operation is simple and convenient for the staff. The oil pot 104 is inserted into the flash point tester by holding the hand grip 102. The positioning column 401 is a common setting of the existing flash point tester. First, a screw hole is set on the table of the flash point tester. The positioning column 401 is installed on the table of the flash point tester through the positioning bolt 402. The positioning bolt 402 is used to facilitate fastening, installation and disassembly. The positioning column 401 is inserted into the positioning column 401 by the suction mounting ring 101 for limiting, ensuring that the lower pressure plate 302 is aligned with the ignition rod of the flash point tester. The heating wire in the flash point tester heats the oil in the oil pot 104 and the suction fan connected to the exhaust pipe 105 is kept powered on to exhaust air. The suction installation ring 101 cooperates with the suction hole 1041 to suck the vapor generated during the flash point test working interval and before the test. The exhaust pipe 105 is led out of the room. As the ignition rod of the flash point tester swings, the flame head at its end passes through the oil pot 104. At this time, the ignition rod of the flash point tester first passes through the inclined plate 3021. The inclined surface structure of the inclined plate 3021 is used to slide over the inclined plate 3021, pressing down the lower pressure plate 302 and compressing the lower pressure spring 202. At this time, the lifting power board 303 is driven to move downward, and the power board 106 Separate, the suction fan external to the exhaust pipe 105 can be powered off, and at this time, it stops absorbing oil vapor, and the oil can evaporate upward. It takes time to cooperate with the displacement of the flash point tester ignition rod during the swing process to ensure that the test oil vapor has time to diffuse upward to above the flame head height, and so on. As the oil temperature rises, a test is performed every few degrees. The specific interval time is determined according to the oil test requirements, until it can be observed that the oil vapor is ignited. At this time, the temperature of the oil is the flash point temperature. Once the flash point tester ignition rod swings and resets, it is misaligned with the lower pressure plate 302, and the lower pressure plate 302 is no longer pressed down. At this time, the suction fan external to the exhaust pipe 105 will continue to suck air to prevent vapor from spreading.
