Description

Technical Field

[0001] This utility model relates to the technical field of biodiesel processing equipment, and in particular to an online monitoring sensor component for oil rancidity. Background Technology

[0002] Biodiesel refers to fatty acid methyl esters or ethyl esters formed by esterification of vegetable oils (such as rapeseed oil, soybean oil, peanut oil, corn oil, cottonseed oil, etc.), animal oils (such as fish oil, lard, tallow, mutton tallow, etc.), waste oils, or microbial oils with methanol or ethanol. Biodiesel is a typical "green energy" with good environmental performance, good engine starting performance, good fuel performance, and a wide range of raw material sources and is renewable. Vigorously developing biodiesel is of great significance for sustainable economic development, promoting energy substitution, reducing environmental pressure, and controlling urban air pollution. During its processing, the rancidity of oils is an extremely important indicator. If it is not controlled in time, it will affect the final product conversion. Free fatty acids and peroxide value are important standards for monitoring the rancidity of oils.

[0003] Currently, during the processing of biodiesel, workers need to hold a testing probe and insert it into the oil storage tank to be tested. The probe is then used to monitor the content of free fatty acids and peroxide value in the oil to determine its rancidity. However, prolonged monitoring can cause hand pain and is highly susceptible to human factors, such as hand tremors, insufficient monitoring depth, and small monitoring range. Utility Model Content

[0004] In view of the above-mentioned problems existing in the prior art, the main purpose of this utility model is to provide an online monitoring sensor component for the rancidity of oils and fats.

[0005] The technical solution of this utility model is as follows: an online monitoring sensor assembly for oil rancidity includes a base, an oil storage tank placed on top of the base, a ring above the oil storage tank, a horizontal support fixedly installed inside the ring, a screw rotatably connected inside the horizontal support, a sliding member threadedly connected to the outer side of the screw, a vertical adjustment member slidably installed inside the sliding member, a locking bolt threadedly connected to the outer side of the sliding member, one end of the locking bolt extending into the interior of the sliding member and abutting against the outer side of the vertical adjustment member, a mounting base fixedly connected to the bottom of the vertical adjustment member, and an electrochemical sensor fixedly installed at the bottom of the mounting base.

[0006] By adopting the above technical solution, the rotation of the screw can drive the sliding part to move horizontally left and right within the transverse support, thereby driving the electrochemical sensor to move. With the cooperation of the steering component, the electrochemical sensor can be moved to any detection point in the oil storage tank, thus expanding the monitoring range of the electrochemical sensor.

[0007] In a preferred embodiment, a steering assembly is provided on the outer side of the ring. The steering assembly includes a support ring disposed on the top of the oil storage tank. The ring is rotatably mounted on the inner wall of the support ring. A gear ring is fixedly connected to the bottom of the ring, and a gear is rotatably connected to the bottom of the support ring.

[0008] By adopting the above technical solution, the rotation of the gear can drive the gear ring to rotate, thereby adjusting the monitoring direction of the electrochemical sensor according to the monitoring requirements.

[0009] In a preferred embodiment, a stabilizing component is provided on the outer side of the support ring. The stabilizing component includes several L-shaped frames fixedly connected to the outer periphery of the support ring. Each L-shaped frame has a tightening post threadedly connected inside. Each tightening post has a clamping member fixedly connected to one end near the ring.

[0010] By adopting the above technical solution, the use of tightening columns can push the corresponding clamping parts to form contact with the outer wall of the oil storage tank, thereby enabling the support ring to be installed on the oil storage tank.

[0011] In a preferred embodiment, the gear ring meshes with a gear, and several L-shaped frames are arranged at equal intervals.

[0012] By adopting the above technical solution, power can be transmitted through the meshing of the gear ring and the gear.

[0013] In a preferred embodiment, a drive motor b is fixedly mounted on the outer side of the transverse support, and the output shaft of the drive motor b extends into the interior of the transverse support and is fixedly connected to the screw.

[0014] By adopting the above technical solution, the rotation of the output shaft of the drive motor b can drive the screw to rotate.

[0015] In a preferred embodiment, a drive motor a is fixedly mounted on the top of the support ring, and the output shaft of the drive motor a is fixedly connected to the rotation shaft of the gear.

[0016] By adopting the above technical solution and setting the drive motor a, a power source can be provided for the rotation of the gear.

[0017] In a preferred embodiment, a handwheel is fixedly connected to the end of the tightening column away from the clamping member.

[0018] By adopting the above technical solution, it is easier for staff to rotate the tightening column.

[0019] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, the rotation of the screw can drive the sliding member to move horizontally left and right within the transverse support, thereby moving the electrochemical sensor. With the cooperation of the steering component, the electrochemical sensor can be moved to any detection point within the oil storage tank, thus expanding the monitoring range of the electrochemical sensor. Furthermore, the monitoring height of the electrochemical sensor can be adjusted by sliding the vertical adjustment member to meet the monitoring needs at different depths. The above method does not require manual hand operation, reducing the impact of human shaking on the monitoring and thus improving the monitoring accuracy of the electrochemical sensor.

[0020] 2. In this utility model, as the tightening column is tightened, the corresponding clamping part can be pushed to form an abutment with the outer wall of the oil storage tank, thereby enabling the support ring to be installed on different oil storage tanks, thus improving the portability of the monitoring structure.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0024] Reference Figure 1-4The online monitoring sensor assembly for oil rancidity includes a base 1, an oil storage tank 2 placed on top of the base 1, a ring 4 positioned above the oil storage tank 2, a horizontal support 7 fixedly installed inside the ring 4, a screw 16 rotatably connected inside the horizontal support 7, a sliding member 17 threadedly connected to the outer side of the screw 16, a vertical adjustment member 9 slidably installed inside the sliding member 17, a locking bolt 18 threadedly connected to the outer side of the sliding member 17, one end of the locking bolt 18 extending into the interior of the sliding member 17 and abutting against the outer side of the vertical adjustment member 9, a mounting base 10 fixedly connected to the bottom of the vertical adjustment member 9, and an electrochemical sensor fixedly installed at the bottom of the mounting base 10. The device 11, through the rotation of the screw 16, can drive the sliding member 17 to move horizontally left and right within the transverse support 7, thereby driving the electrochemical sensor 11 to move. With the cooperation of the steering component, the electrochemical sensor 11 can be moved to any detection point within the oil storage tank 2, thus expanding the monitoring range of the electrochemical sensor 11. Furthermore, by sliding the vertical adjustment member 9, the monitoring height of the electrochemical sensor 11 can be adjusted to meet the monitoring needs of different depths. The above method does not require manual hand operation, reducing the impact of human shaking on the monitoring and thus improving the monitoring accuracy of the electrochemical sensor 11.

[0025] Specifically, a steering assembly is provided on the outer side of the ring 4. The steering assembly includes a support ring 3 located on the top of the oil storage tank 2. The rotation of the gear 15 drives the gear ring 12 to rotate, thereby adjusting the monitoring direction of the electrochemical sensor 11 according to monitoring requirements. The ring 4 is rotatably mounted on the inner wall of the support ring 3. The gear ring 12 is fixedly connected to the bottom of the ring 4, and the gear 15 is rotatably connected to the bottom of the support ring 3. A stabilizing assembly is provided on the outer side of the support ring 3. The stabilizing assembly includes several L-shaped rings fixedly connected to the outer circumference of the support ring 3. As the tightening column 14 is tightened, the L-shaped frame 5 can push the corresponding clamping member 13 to abut against the outer wall of the oil storage tank 2, thereby enabling the support ring 3 to be installed on different oil storage tanks 2, thus improving the portability of the monitoring structure and making the electrochemical sensor 11 more stable during monitoring and less prone to shaking. The L-shaped frame 5 is threaded with the tightening column 14 inside, and the clamping member 13 is fixedly connected to the end of the tightening column 14 near the ring 4. The gear ring 12 is meshed with the gear 15, and several L-shaped frames 5 are arranged at equal intervals.

[0026] Specifically, a drive motor b8 is fixedly installed on the outer side of the transverse support 7. The output shaft of the drive motor b8 extends into the interior of the transverse support 7 and is fixedly connected to the screw 16. The rotation of the output shaft of the drive motor b8 can drive the screw 16 to rotate, thereby realizing the transmission of power. A drive motor a6 is fixedly installed on the top of the support ring 3. The output shaft of the drive motor a6 is fixedly connected to the rotation shaft of the gear 15. The setting of the drive motor a6 can provide a power source for the rotation of the gear 15. A handwheel is fixedly connected to the end of the tightening column 14 away from the clamping part 13 to facilitate the operator to rotate the tightening column 14.

[0027] Working principle: First, before monitoring, the operator can use the handwheel to tighten the corresponding tightening column 14. As the tightening column 14 is tightened, it can push the corresponding clamping part 13 to form contact with the outer wall of the oil storage tank 2, thereby installing the support ring 3 and the components above it. Then, by sliding the vertical adjustment part 9, the monitoring height of the electrochemical sensor 11 can be adjusted, and the position of the vertical adjustment part 9 can be locked with the locking bolt 18. Then, the drive motor b8 can be started by the external control device to drive the screw 16 to rotate, which can drive the sliding part 17 to move horizontally left and right within the transverse support 7, thereby moving the electrochemical sensor 11. By rotating the gear 15, the gear ring 12 can be rotated, allowing the electrochemical sensor 11 to move to any detection point in the oil storage tank 2, thereby expanding the monitoring range of the electrochemical sensor 11. The above method does not require manual operation, so the monitoring is less affected by human shaking, thereby improving the monitoring accuracy of the electrochemical sensor 11.
