Description

Technical Field

[0001] The present invention relates to the field of liquid level detection, and in particular to a highly corrosion-resistant and explosion-proof liquid level meter. Background Art

[0002] A liquid level gauge is an instrument used to measure the level of liquid in a container. A rope-type level gauge is a common type of level gauge. Its core principle is to directly contact the measured liquid with a float, using buoyancy balance or rope displacement to reflect liquid level changes. In reactors and storage tanks in the chemical, petroleum, and pharmaceutical industries, real-time liquid level monitoring can prevent safety incidents (such as leaks and explosions) caused by overflow, as well as equipment damage caused by dry-burning due to low liquid levels.

[0003] Patent document CN113295233A proposes a multifunctional tank level meter that measures the tank liquid level, the interface height between different liquids below the liquid surface, liquid density, liquid temperature, and liquid pressure.

[0038] Example

[0039] This embodiment proposes a highly corrosion-resistant and explosion-proof liquid level gauge, such as Figure 1 As shown, it includes a storage tank 1, a plurality of annular bases 2 distributed at equal angles are fixedly installed on the bottom of the storage tank 1, a feeding port 3 for pouring chemical liquid is opened at the top of the storage tank 1 and near the center, and a guardrail is fixedly installed on the top of the storage tank 1.

[0040] like Figure 2 and Figure 3 As shown, a partition 4 is fixedly installed inside the storage tank 1 near the top. A layer exists between the top of the partition 4 and the storage tank 1. A liquid level detector 5 is installed inside the storage tank 1. The liquid level detector 5 includes a float 53 and floats in the chemical liquid through the float 53. A reel assembly is installed on the top of the partition 4. The reel assembly includes a reel shaft 51. A pull rope 52 is fixedly installed on the curved surface of the reel shaft 51. The bottom end of the pull rope 52 is fixedly installed with the float 53. A torque spring is elastically connected between the reel shaft 51 and the pull rope 52. The torque spring automatically reels the pull rope 52 during the rise and fall of the float 53 to prevent the pull rope 52 from bending and being immersed in the liquid.

[0041] The float 53 is lowered to float on the liquid surface. The gravity of the float 53 and the buoyancy it receives 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 opened in the middle of the partition 4, and the pull rope 52 passes through the through hole. A ball is connected to the through hole for rolling. The pull rope 52 contacts the ball, and the friction between the pull rope 52 and the partition 4 is reduced by the ball.

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

[0044] There is a distance between the floating plate 55 and the buoy 53. The inner arc surface of the slip ring 54 slides with the buoy 53 near the top. The floating plate 55 adopts a hollow polytetrafluoroethylene plate to reduce the gravity of the floating plate 55 and facilitate it to float with the liquid surface. The buoy 53 adopts a stainless steel cylinder, and the center of gravity of the buoy 53 is located at its center.

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

[0046] Initially, the float 55 is in the middle of the buoy 53 and is in the same plane as the center of gravity of the buoy 53. When the buoy 53 is in a balanced state, the part of the buoy 53 immersed in the liquid is less than the volume above the liquid surface. When its center of gravity is higher than its center of buoyancy, the float 55 moves downward from the center of gravity of the buoy 53 to the center of buoyancy of the float 55. The float 55 uses the connecting rod 56 to recover the hydraulic oil from the hydraulic telescopic rod 59 to the hydraulic syringe 57, so that the hydraulic telescopic rod 59 contracts and the position of the magnetic piece changes. The magnetic piece applies a thrust to the first magnetic block 61, thereby putting the water inside the water syringe 510 into the buoy 53 to increase the gravity of the buoy 53, so that the buoyancy center and the center of gravity of the buoy 53 are at the same height. The hydraulic telescopic rod 59 makes a small displacement, and the piston inside the water syringe 510 can make a large displacement.

[0047] When the float 53 is in a balanced state, the part of the float 53 immersed in the liquid is larger than the volume above the liquid surface, and the height of its center of gravity is lower than the height of its center of buoyancy. At this time, 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 internal hydraulic pressure of the hydraulic syringe 57 into the hydraulic telescopic rod 59, so that the hydraulic telescopic rod 59 extends, so that the position of the magnetic part changes, and the magnetic part applies suction to the first magnetic block 61. The first magnetic block 61 moves to pull the water syringe 510, thereby pumping out the water in the float 53 and reducing the overall gravity of the float 53. The center of gravity of the float 53 can be raised, 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 buoyancy, water is added to the float 53 to increase the gravity of the float 53 and change its center of gravity height; and when the center of gravity of the float 53 is lower than its buoyancy height, the water inside the float 53 is pumped out to reduce the gravity of the float 53 and change its center of gravity height, so that the liquid level is measured based on the center of gravity of the float ball of the float 53, thereby reducing the detection error. At the same time, when testing different liquids, the center of gravity can be used as the standard for detection.

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

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

[0051] like Figure 6As shown, an intermediate 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-shock water pipe 68 passes through the middle of the pull rope 52. The pull rope 52 adopts a hose with an internal supporting steel wire. The anti-shock water pipe 68 extends into the interior of the float 53. The hose with the supporting steel wire inside the pull rope 52 prevents the anti-shock water pipe 68 from being compressed when the reel 51 reels the pull rope 52. The anti-shock water pipe 68 located in the float 53 adopts a spiral structure to control the water outlet direction of the anti-shock water pipe 68 to prevent the water released from the anti-shock water pipe 68 from exerting a downward impact force on the float 53.

[0052] When the gravity and buoyancy of float 53 are not at the same height, intermediate insulating block 65 remains misaligned with first magnetic block 61. At this point, second magnetic block 64 or third magnetic block 66 aligns with first magnetic block 61, and first magnetic block 61 remains subject to external force. Water injector 510 continuously releases or pumps water until the center of gravity and buoyancy of float 53 are at the same height. Pumping water is not done directly by displacement of connecting rod 56 to prevent the possibility of air being drawn into displacement pumping, which could prevent a fixed amount of water from being pumped out.

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

[0054] When the gravity and buoyancy of the float 53 are not at the same height, in order to adjust the state of the gravity of the float 53, the water injector 510 continuously releases or pumps water until the gravity 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 tube 71. The gathering tube 71 adopts a trumpet-shaped structure. The outer arc surface of the gathering tube 71 is fixedly connected to the partition 4. A condenser 72 is fixedly installed on the top of the gathering tube 71. A water storage tank 73 is fixedly installed at the end of the condenser 72. The water storage tank 73 is connected to a guide pipe 74 on the side facing the pull rope 52. The water vapor evaporated from the liquid inside the storage tank 1 is collected by the gathering tube 71, condensed by the condenser 72, and stored in the water storage tank 73.

[0056] The side of the water reservoir 73 facing the pull rope 52 is connected to a flow guide tube 74. A blocking door 75 is rotatably connected to the interior of the flow guide tube 74. A coil spring 76 is elastically connected between the blocking door 75 and the flow guide tube 74. When the pressure of the water in the water reservoir 73 on the blocking door 75 exceeds the elastic force of the coil spring 76, the blocking door 75 opens, flushing the water in the water reservoir 73 toward the pull rope 52, removing any debris attached to its surface.

[0057] By accumulating evaporated water vapor, 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, and the water in the water storage tank 73 is flushed toward the pull rope 52, removing the attachments on its surface, preventing the attachments from affecting the friction of its winding, affecting the height of the float 53, and then 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 inspirations of the above embodiments, those skilled in the art may make various alternative improvements and combinations to the above specific embodiments.
