Description

Technical Field

[0001] The utility model relates to the technical field of flash point analyzers, and particularly relates to a flash point analyzer. Background Art

Therefore, after the oil liquid is produced, it is necessary to measure the flash point of the oil liquid and store it in different situations according to the measured flash point.

[0003] Chinese patent document CN217688671 U discloses an ignition device for an oil liquid flash point analyzer and an oil liquid flash point analyzer.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] In order to make the technical means, creative features, achieved purposes and functions realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0027] As Figure 1 and Figure 2 shown, a flash point analyzer includes an analyzer body 1. A display screen 5 is fixedly installed on the front side of the analyzer body 1. A heating and analysis component 2 is fixedly installed in the middle of the upper end of the analyzer body 1. A fire extinguishing component 3 is fixedly installed on the left side of the analyzer body 1. A sweeping and ignition component 4 is fixedly installed on the rear part of the analyzer body 1.

[0028] Through the heating and analysis component 2, the solution in the oil cup 22 can be heated to the estimated temperature, and the detection probe 25 can detect the oil temperature. Through the fire extinguishing component 3, when the oil catches fire accidentally after the oil flash point, the cover 35 can be quickly moved above the oil cup 22, thereby blocking the oil cup 22 to prevent the oil gas from continuing to contact the air and accelerating combustion. In this process, the staff does not need to contact the cover 35, and later does not need to manually remove the high-temperature cover 35 when the analyzer cools down as a whole, improving the practicability of the device. Through the sweeping and ignition component 4, when the sweeping mechanism 43 fails, it can be freely converted to manual sweeping of the electric heating wire 47, saving time and ensuring the continuity of the experiment and the timeliness of data collection.

[0029] As Figure 2 and Figure 3 shown, the heating and analysis component 2 includes a heating furnace 21. The lower end of the heating furnace 21 is fixedly installed in the middle of the upper end of the analyzer body 1. The output end of the heating furnace 21 is lapped with an oil cup 22. An installation plate 23 is fixedly installed at the rear part of the upper end of the analyzer body 1. A storage groove is opened at the top of the front side of the installation plate 23. A lifting frame 24 is movably connected to the inner wall of the storage groove. A detection probe 25 is fixedly installed at the front lower part of the front part of the lifting frame 24.

[0030] The heating furnace 21 is an existing mechanism, and its structure is similar to that of a furnace body. The oil cup 22 can be heated in its annular heating groove. The lifting frame 24 can move up and down in the storage groove. A fixed frame is fixedly installed at the bottom of the inner wall of the storage groove. The lifting frame 24 moves up and down in the fixed frame through two hydraulic rods. When the oil cup 22 is heated, the detection probe 25 extends into the oil to detect the temperature at the flash point of the oil.

[0031] As Figure 3 and Figure 4As shown, the fire extinguishing component 3 includes a connecting plate 31. The lower end of the connecting plate 31 is fixedly connected to the left part of the upper end of the analyzer body 1. The bottom of the left side of the connecting plate 31 is fixedly installed with a bottom plate 32. The middle part of the upper end of the bottom plate 32 is rotatably connected with a rotating column 33. The front part of the outer wall of the rotating column 33 is fixedly installed with a moving plate 34. A sliding groove is opened on the left side of the connecting plate 31. The upper and lower ends of the moving plate 34 are slidably connected to the inner wall of the sliding groove. One end of the moving plate 34 away from the rotating column 33 is fixedly installed with a cover 35. The lower end of the cover 35 abuts against the upper end of the oil cup 22.

[0032] By rotating the rotating column 33, the moving plate 34 can be driven to move in the sliding groove, so that the cover 35 can be moved to the upper end of the oil cup 22 to cover it when the flame rises, achieving the effect of isolating air.

[0033] As Figure 3 、 Figure 4 and Figure 5 shown, a fixed disk 36 is fixedly sleeved on the bottom of the outer wall of the rotating column 33. Two arc-shaped adjustment grooves 37 are opened on the front part of the upper end of the fixed disk 36. An installation groove 38 is opened on the front part of the upper end of the bottom plate 32. A sliding rod 39 is fixedly installed on the inner wall of the installation groove 38. A slider 310 is slidably connected to the outer wall of the sliding rod 39. A fixed rod 311 is fixedly installed on the upper end of the slider 310. The top of the outer wall of the fixed rod 311 abuts against the inner walls of the two adjustment grooves 37.

[0034] When it is necessary for the cover 35 to block the oil cup or leave the oil cup 22, pull the fixed rod 311. The fixed rod 311 leaves the corresponding adjustment groove 37 and compresses the spring 312. At the same time, the fixed rod 311 drives the slider 310 to move in the installation groove 38. Rotate the rotating column 33. The rotating column 33 drives the fixed disk 36 to rotate, so that another adjustment groove 37 on the fixed disk 36 is aligned with the fixed rod. After releasing the fixed rod 311, the elastic restoring force of the spring 312 drives the fixed rod 311 to reset, so that the rotating column 33 can be fixed. In this way, the cover 35 can be fixed whether it leaves or is located at the upper end of the oil cup 22. Among them, one adjustment groove 37 is located at the front part of the upper end of the fixed disk 36, and the other adjustment groove 37 is located at the right part of the front part of the upper end of the fixed disk 36. The angle between the two adjustment grooves 37 is between 60° and 90°.

[0035] As Figure 5 shown, a spring 312 is movably sleeved on the front part of the outer wall of the sliding rod 39. The rear end of the spring 312 is fixedly connected to the front side of the slider 310. The front end of the spring 312 is fixedly connected to the front part of the inner wall of the installation groove 38.

[0036] The spring 312 plays a role in resetting the movement of both the fixed rod 311 and the slider 310.

[0037] As Figure 6As shown in the figure, the sweeping ignition assembly 4 includes a mounting bracket 41. The front end of the mounting bracket 41 is fixedly connected to the bottom of the rear side of the mounting plate 23. The middle part of the inner wall of the mounting bracket 41 is rotatably connected to a rotating shaft 42. The lower end of the mounting bracket 41 is fixedly installed with a sweeping mechanism 43. The top of the sweeping mechanism 43 is movably connected to the bottom of the outer wall of the rotating shaft 42. The upper end of the rotating shaft 42 is fixedly installed with a connecting frame 44.

[0038] The sweeping mechanism 43 is a common mechanism, which includes an electric push rod, a rack and a gear. The gear is fixedly sleeved on the bottom of the outer wall of the rotating shaft 42. The rack is slidably connected to the front part of the lower end of the mounting bracket 41. The electric push rod drives the rack, and the gear drives the rotating shaft 42 to rotate by meshing with the gear, and the rotating shaft 42 drives the connecting frame 44 to rotate.

[0039] As Figure 6 and Figure 7 shown in the figure, the middle part of the upper end of the connecting frame 44 is lapped with a bottom column 45. The upper end of the bottom column 45 is fixedly installed with an ignition plate 46. A moving groove is opened in the middle of the rear side of the mounting plate 23. The upper and lower sides of the ignition plate 46 are slidably connected to the inner wall of the moving groove. An electric heating wire 47 is movably arranged on the front side of the ignition plate 46.

[0040] Through the rotation of the connecting frame 44 and the rotating shaft 42, the ignition plate 46 rotates in the moving groove, and the ignition plate 46 drives the electric heating wire 47 to perform a sweeping operation above the oil cup 22. Among them, the ignition plate 46 is a hollow structure, and a heating device is fixedly installed inside it. The heating device is movably connected to the electric heating wire 47. The heating device heats the electric heating wire 47. When the electric heating wire 47 reaches a certain temperature, the rising oil-gas and air mixture contacts the high-temperature electric heating wire, generating a phenomenon of instantaneous combustion.

[0041] As Figure 7 shown in the figure, a plug rod 48 passing through the left part of the connecting frame 44 is slidably connected to the left side of the connecting frame 44. A through hole is opened in the right part of the outer wall of the bottom column 45. The inner wall of the plug rod 48 is movably sleeved with the outer wall of the through hole. A return spring 49 is movably sleeved on the left part of the outer wall of the plug rod 48. The right end of the return spring 49 is fixedly connected to the left side of the connecting frame 44, and the left end of the return spring 49 is fixedly connected to the left part of the outer wall of the plug rod 48.

[0042] When an internal failure occurs in the subsequent sweeping mechanism 43, pull the plug rod 48 to make the plug rod 48 move away from the through hole and compress the return spring 49, so as to release the fixation of the bottom column 45. When detecting the flash point, the electric heating wire 47 can be swept manually instead of the sweeping mechanism 43, ensuring the timeliness of the experimental results.

[0043] Working principle of the utility model: First, the staff adds the required oil into the oil cup 22, and then places the oil cup 22 on the heating furnace 21. The display screen 5 is a touch-screen structure. After the staff sets the predetermined flash point of the material, the lifting frame 24 is started, so that the lifting frame 24 drives the detection probe 25 to move downward, and the detection probe 25 extends into the oil. Subsequently, the heating furnace 21 is started, and the heating furnace 21 heats the oil in the oil cup 22. After the oil is heated, sufficient steam is generated on its surface to mix with air to form a combustible gas. When the analyzer reaches the predetermined flash point, the sweeping mechanism 43 and the electric heating wire 47 are started. The sweeping mechanism 43 drives the rotating shaft 42 to rotate according to the actual set time, and the rotating shaft 42 drives the connecting frame 44 and the bottom column 45 to rotate, so that the ignition plate 46 and the electric heating wire 47 reciprocally sweep. The high temperature of the electric heating wire 47 contacts the combustible gas to produce a phenomenon of instantaneous combustion. The analyzer automatically records the oil temperature at this time, and the display screen 5 displays the data.

[0044] After the flash point of the oil, it is easy for the surface of the oil to catch fire due to an open flame. The staff can pull the fixed rod 311 to disengage the fixed rod 311 from an adjustment groove 37, rotate the rotating column 33 to a specified angle, and the rotating column 33 drives the moving plate 34 and the cover 35 to rotate towards the oil cup 22 until the cover 35 blocks the oil cup 22. The cover 35 can isolate the air and prevent the spread of fire. After releasing the fixed rod 311, the elastic potential energy of the spring 312 drives the slider 310 and the fixed rod 311 to reset, so that the fixed rod 311 re-enters a new adjustment groove 37, thereby fixing the cover 35 and the moving plate 34.

[0045] During the heating process of the oil or during the continuous operation of the analyzer, if the sweeping mechanism fails, pull the insertion rod to disengage the insertion rod 48 from the through hole and stretch the return spring 49, so that the staff can manually rotate the ignition plate 46 to move the ignition plate 46 in the moving groove and achieve the sweeping work, improving the flexibility of the analyzer body 1. After a series of experiments are completed, replace or repair the sweeping mechanism 43. Subsequently, only need to pull the insertion rod 48 to align the insertion rod 48 with the through hole. After releasing the insertion rod 48, the elastic restoring force of the return spring 49 can drive the insertion rod 48 to fix the bottom column 45, thereby reconnecting the ignition plate 46 with the sweeping mechanism 43.
