Description

Technical Field

[0001] This invention relates to the field of liquid level detection, and more particularly to a highly corrosion-resistant and explosion-proof liquid level gauge. Background Technology

[0002] A level gauge is an instrument used to measure the level of a liquid medium in a container. A pull-rope level gauge is a common type. Its core principle is to use a float that directly contacts the liquid being measured, utilizing buoyancy balance or the displacement of the pull-rope to reflect changes in liquid level. In reaction vessels and storage tanks in industries such as chemical, petroleum, and pharmaceuticals, real-time monitoring of liquid levels can prevent liquid overflows that could lead to safety accidents (such as leaks or explosions), or damage to equipment due to excessively low liquid levels.

[0003] The patent document with publication number CN113295233A proposes a multifunctional tank level gauge, which has the functions of measuring tank level, interface height between different liquids below the liquid surface, liquid density, liquid temperature, and liquid pressure. It consists of a controller, servo motor, hub, dynamic and static slip ring circuit coupling device, transmission cable, measuring box, and magnetostrictive height measuring component. This level gauge has no special requirements for the measurement environment and the measured medium. The measurement data is safe and reliable, the measurement accuracy is high, the measurement functions are comprehensive, the application range is wide, the structure is simple, and the installation is convenient.

[0004] In float-based liquid level detection, measuring the liquid level at the center of gravity of the float is theoretically ideal. However, in actual use, the density of the liquid affects the depth to which the float floats, i.e., the height of the center of buoyancy. The center of gravity of the float and the center of buoyancy are not at the same height, which affects the accuracy of the detection. Summary of the Invention

Initially, the intermediate insulating block is located on the extension line of the end of the water injector. An intermediate water pipe is fixedly installed at the end of the water injector.

[0014] Optionally, the side of the first magnetic block facing the middle insulating block is the S pole, the side of the second magnetic block facing the first magnetic block is the S pole, and the side of the third magnetic block facing the first magnetic block is the N pole.

[0015] Optionally, an insulating sheet is fixedly installed at the connection between the first magnetic block and the water syringe, and a return spring is elastically connected between the pull rope and the tube of the water syringe.

[0016] Optionally, a flushing assembly is provided on the top of the partition. The flushing assembly includes a gathering cylinder with a trumpet-shaped structure.

[0019] Compared with the prior art, the present invention has the following beneficial technical effects:

[0020] 1. This invention allows for the addition of water to the float when its center of gravity is higher than its center of buoyancy, thereby increasing the float's weight and changing its center of gravity. Conversely, when the float's center of gravity is lower than its center of buoyancy, the water is removed to reduce the float's weight and change its center of gravity. This allows for the measurement of liquid level using the center of gravity of the float's buoy as a reference point, reducing detection errors. Furthermore, this invention enables the measurement of different liquids using the center of gravity as a reference point.

[0021] 2. In this invention, when the weight and buoyancy of the float are not at the same height, the middle insulating block is always misaligned with the first magnetic block. At this time, the second or third magnetic block is aligned with the first magnetic block. The first magnetic block is always subjected to external force, and the water injector continuously releases or pumps water until the center of gravity and buoyancy of the float are at the same height.

[0022] 3. This invention uses the accumulated evaporated water vapor. When the pressure of the water inside the water tank on the blocking door is greater than the elastic force of the coil spring, the blocking door opens, flushing the water in the water tank toward the pull rope, removing the adhering substances on its surface, and preventing the adhering substances from affecting the friction of its winding, affecting the height of the float, and thus affecting the detection data.

[0038] Example

[0039] This embodiment proposes a highly corrosion-resistant and explosion-proof level gauge, such as... Figure 1 As shown, the tank includes a storage tank 1. Multiple annular bases 2 are fixedly installed at the bottom of the storage tank 1. An inlet 3 for filling chemical liquid is opened at the top of the storage tank 1 near the center. A protective railing is fixedly installed on the top of the storage tank 1.

[0040] like Figure 2 and Figure 3 As shown, a baffle 4 is fixedly installed inside the storage tank 1 near the top. There is a sandwich between the top of the baffle 4 and the storage tank 1. A liquid level detection element 5 is installed inside the storage tank 1. The liquid level detection element 5 includes a float 53, which floats in the chemical liquid. A winding assembly is installed at the top of the baffle 4. The winding assembly includes a winding shaft 51. A pull rope 52 is fixedly installed on the arc surface of the winding shaft 51. The float 53 is fixedly installed at the bottom end of the pull rope 52. A torque spring is elastically connected between the winding shaft 51 and the float 53. During the rising and falling of the float 53, the torque spring automatically winds up the pull rope 52 to prevent the pull rope 52 from bending and being submerged in the liquid.

[0041] The float 53 is lowered to float on the surface of the liquid. The weight of the float 53 and the buoyancy it experiences are balanced. The height of the float 53 can be determined by the length of the rope 52 that is released.

[0042] A through hole is provided in the middle of the partition 4. The pull rope 52 passes through the through hole and is connected to a ball bearing in the through hole. The pull rope 52 contacts the ball bearing, and the ball bearing reduces the friction between the pull rope 52 and the partition 4.

[0043] like Figure 4 and Figure 5 As shown, a slip ring 54 is slidably connected to the surface of the float 53. A float plate 55 is fixedly installed at the bottom of the slip ring 54. A hydraulic injector 57 is fixedly installed at the top of the float 53. A connecting rod 56 is fixedly installed between the top of the slip ring 54 and the hydraulic injector 57. The hydraulic injector 57 is connected to a hydraulic telescopic rod 59. A hydraulic pipe 58 is fixedly connected between the hydraulic injector 57 and the hydraulic telescopic rod 59. The hydraulic pipe 58 adopts a helical spring structure to prevent the hydraulic pipe 58 from being submerged in liquid. The surfaces of the float (53), slip ring (54), and float plate (55) are all coated with an anti-corrosion coating.

[0044] There is a gap between the float plate 55 and the float 53. The inner arc surface of the slip ring 54 and the position near the top slide with the float 53. The float plate 55 is made of hollow polytetrafluoroethylene plate to reduce the weight of the float plate 55 and facilitate its floating on the liquid surface. The float 53 is made of stainless steel cylinder and the center of gravity of the float 53 is located at its center.

[0045] like Figure 3 and Figure 7 As shown, a force-applying component 6 is provided on the top of the partition 4. The force-applying component 6 includes a first magnetic block 61. The side of the first magnetic block 61 is fixedly connected to the water injector 510. A magnetic component is provided at the end of the push-pull rod of the hydraulic telescopic rod 59. The magnetic component is located on the extension line of the end of the water injector 510.

[0046] Initially, the float 55 is located in the middle of the float 53 and is on the same plane as the center of gravity of the float 53. When the float 53 is in equilibrium, the part of the float 53 submerged in the liquid is less than the volume above the liquid surface, and its center of gravity is higher than its center of buoyancy. At this time, the float 55 moves downward and falls from the center of gravity of the float 53 to the center of buoyancy of the float 55. The float 55 uses the connecting rod 56 to recycle the hydraulic oil from the hydraulic telescopic rod 59 to the hydraulic injector 57, so that the hydraulic telescopic rod 59 retracts, the position of the magnetic component changes, and the magnetic component applies a thrust to the first magnetic block 61, thereby putting water from the water injector 510 into the float 53 to increase the weight of the float 53, so that the center of buoyancy of the float 53 is at the same height as the center of gravity. The hydraulic telescopic rod 59 makes a small displacement, and the piston inside the water injector 510 can make a large displacement.

[0047] When the float 53 is in equilibrium, the portion of the float 53 submerged in the liquid is greater than the volume above the liquid surface. When its center of gravity is lower than its center of buoyancy, the float plate 55 is moved upward by the buoyancy of the liquid and moves to the center of buoyancy of the float 53. The float plate 55 uses the connecting rod 56 to push the hydraulic injector 57 into the hydraulic telescopic rod 59, so that the hydraulic telescopic rod 59 extends, causing the position of the magnetic component to change. The magnetic component applies an attractive force to the first magnetic block 61. The first magnetic block 61 moves to pull the water injector 510, thereby drawing out the water in the float 53, reducing the overall weight of the float 53, and thus raising the center of gravity of the float 53 so that the center of buoyancy and the center of gravity of the float 53 are at the same height.

[0048] In summary, when the center of gravity of the float 53 is higher than its center of buoyancy, water is added to the float 53 to increase its weight and change its center of gravity. When the center of gravity of the float 53 is lower than its center of buoyancy, water is removed from the float 53 to reduce its weight and change its center of gravity. The liquid level is measured using the center of gravity of the float 53 as a reference, reducing detection errors. Furthermore, the center of gravity can be used as a reference for detection when testing different liquids.

[0049] The magnetic component includes a second magnetic block 64, which is fixedly installed at the end of the hydraulic telescopic rod 59. An intermediate insulating block 65 is fixedly installed on the side of the second magnetic block 64 away from the hydraulic telescopic rod 59, and a third magnetic block 66 is fixedly installed on the side of the intermediate insulating block 65 away from the slip ring 54. Initially, the intermediate insulating block 65 is located on the end extension line of the water injector 510. An intermediate water pipe 67 is fixedly installed at the end of the water injector 510. The end of the hydraulic injector 57 is connected to a hydraulic pipe 58. The anti-impact water pipe 68 passes through the middle of the pull rope 52. The pull rope 52 is a flexible hose with internal supporting steel wires. The anti-impact water pipe 68 extends into the interior of the float 53. The anti-impact water pipe 68 located inside the float 53 has a spiral structure.

[0050] The side of the first magnetic block 61 facing the middle insulating block 65 is the S pole, the side of the second magnetic block 64 facing the first magnetic block 61 is the S pole, and the side of the third magnetic block 66 facing the first magnetic block 61 is the N pole. When the center of gravity of the float 53 is higher than its buoyancy center, the hydraulic telescopic rod 59 extends, causing the second magnetic block 64 to move to the end extension line of the water injector 510. The second magnetic block 64 and the first magnetic block 61, being of the same polarity, hold each other, and the first magnetic block 61 pushes the water injector 510 to release water into the float 53. When the center of gravity of the float 53 is lower than its buoyancy center, the hydraulic telescopic rod 59 retracts, causing the third magnetic block 66 to move to the end extension line of the water injector 510. Due to the attraction between opposite poles, the water inside the float 53 is drawn into the water injector 510.

[0051] like Figure 6As shown, a middle water pipe 67 is fixedly installed at the end of the water injector 510, and a hydraulic pipe 58 is connected to the end of the hydraulic injector 57. The anti-impact water pipe 68 passes through the middle of the pull rope 52. The pull rope 52 is a flexible hose with internal supporting steel wires. The anti-impact water pipe 68 extends into the interior of the float 53. The flexible hose with supporting steel wires inside the pull rope 52 prevents the reel 51 from compressing the anti-impact water pipe 68 when reeling in the pull rope 52. The anti-impact water pipe 68 located inside the float 53 has a spiral structure to control the water outlet direction at the anti-impact water pipe 68 and prevent the water released from the anti-impact water pipe 68 from exerting a downward impact force on the float 53.

[0052] When the weight and buoyancy of the float 53 are not at the same height, the intermediate insulating block 65 is always misaligned with the first magnetic block 61. At this time, the second magnetic block 64 or the third magnetic block 66 is aligned with the first magnetic block 61, and the first magnetic block 61 is always subjected to external force. The water injector 510 continuously releases or pumps water until the center of gravity and buoyancy of the float 53 are at the same height. Not directly using the displacement of the connecting rod 56 to pump water prevents air from being drawn in during displacement pumping, thus preventing the extraction of a fixed amount of water.

[0053] An insulating sheet 62 is fixedly installed at the connection between the first magnetic block 61 and the water syringe 510. A return spring 63 is elastically connected between the pull rope 52 and the tube of the water syringe 510. The insulating sheet 62 prevents the magnetic force from acting on the return spring 63. The return spring 63 is used to reset the first magnetic block 61.

[0054] When the weight and buoyancy of the float 53 are not at the same height, in order to adjust the weight of the float 53, the water injector 510 continuously releases or pumps water until the weight and buoyancy of the float 53 are at the same height.

[0055] like Figure 8 and Figure 9 As shown, a flushing assembly 7 is provided on the top of the partition 4. The flushing assembly 7 includes a gathering cylinder 71, which has a trumpet-shaped structure. The outer arc surface of the gathering cylinder 71 is fixedly connected to the partition 4. A condenser pipe 72 is fixedly installed on the top of the gathering cylinder 71, and a water storage tank 73 is fixedly installed at the end of the condenser pipe 72. A guide pipe 74 is connected to the side of the water storage tank 73 facing the pull rope 52. Water vapor evaporated from the liquid inside the storage tank 1 is collected by the gathering cylinder 71, condensed by the condenser pipe 72, and the water is stored in the water storage tank 73.

[0056] A guide pipe 74 is connected to the side of the water storage tank 73 facing the pull rope 52. A blocking door 75 is rotatably connected inside the guide pipe 74, and a coil spring 76 is elastically connected between the blocking door 75 and the guide pipe 74. When the pressure of the water inside the water storage tank 73 on the blocking door 75 is greater than the elastic force of the coil spring 76, the blocking door 75 opens, flushing the water in the water storage tank 73 toward the pull rope 52 to remove the adhering substances on its surface.

[0057] By accumulating evaporated water vapor, when the pressure of the water inside the water tank 73 on the blocking door 75 is greater than the elastic force of the coil spring 76, the blocking door 75 opens, flushing the water in the water tank 73 toward the pull rope 52, removing the adhering substances on its surface, and preventing the adhering substances from affecting the friction of its winding, affecting the height of the float 53, and thus affecting the detection data.

[0058] The above specific embodiments are merely several optional embodiments of the present invention. Based on the technical solutions of the present invention and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
