Description

Technical Field

[0001] This utility model relates to the field of chemical safety technology, and in particular to a corrosion-resistant liquid level monitoring device. Background Technology

[0002] In the chemical industry, storage tanks are often used to store chemicals. Many chemicals are corrosive, toxic, or flammable. To prevent leaks or spills from the storage tanks that could pollute the surrounding environment, workers usually install level monitoring devices on the storage tanks to monitor the level of the chemicals. Existing level monitoring devices typically consist of a pipe body, connecting flanges, a magnetic float, and a drain valve.

[0003] For example, utility model patent application number CN202010493559.8 discloses a magnetic float level gauge. Specifically, this utility model relates to the field of instrumentation technology and discloses a magnetic float level gauge, including a tube body. Connecting flanges are fixedly installed on the top and bottom of one side of the tube body, a drain valve is fixedly installed on the bottom of the tube body, and a scale strip is fixedly installed on the other side of the tube body. A flip box is fixedly installed on the outer ring of the tube body on the front of the scale strip, and a small magnetic flip column is movably installed inside the flip box. A precision reading box is fixedly installed on the back of the scale strip on the outer ring of the tube body. A guide post is fixedly installed on the top wall of the inner tube body, and a magnetic float is movably sleeved on the outer ring of the guide post. Slide grooves are opened on both sides inside the precision reading box, and a precision reading device is movably sleeved in the slide grooves. By setting the magnetic float to be sleeved on the guide post and maintaining a certain distance between the outer ring and the inner wall of the tube body, and by setting the precision reading box and cooperating with the U-shaped magnet installed in the magnetic float, the blockage of the magnetic float is effectively prevented, and the measurement accuracy is improved.

[0004] However, the chemicals stored in the storage tanks often contain unreacted raw material particles and precipitates generated from the reaction. With prolonged use of the level monitoring device, these precipitates gradually accumulate at the bottom of the level gauge. To prevent the accumulated precipitates from clogging the drain valve, staff usually need to periodically remove the drain valve to clean these accumulated precipitates. However, the drain valve of the existing level monitoring device is usually fixed to the pipe body by a flange. This requires staff to tighten numerous bolts on the flange one by one during the disassembly of the drain valve, which is cumbersome, increases the labor intensity of the staff, affects the maintenance efficiency of the level monitoring device, and makes it inconvenient to use. Utility Model Content

[0005] In view of this, the present invention provides a corrosion-resistant liquid level monitoring device, which has a locking bracket and locking seat that allow workers to quickly and easily disassemble the drain valve. Simply by moving the fixing column, it slides along the guide groove. As the fixing column slides, it drives the control gear ring to rotate. During the rotation of the control gear ring, it also drives the guide ring to slide within the fixing ring, providing guidance for the control gear ring. The rotation of the control gear ring drives the meshing transmission gear to rotate, which in turn drives the transmission shaft to rotate. The rotation of the shaft will cause the locking bracket to flip. As the locking bracket flips, it will disengage from the locking seat. At this time, the operator can remove the mounting plate and the drain valve. In the initial state, the limit wedge is inserted into the limit slot to limit the control block, preventing the fixed column from sliding accidentally and ensuring the fixing effect between the fixed ring and the mounting plate. When it is necessary to move the control block, the operator only needs to pull the auxiliary slide, which will move the limit wedge and squeeze the support spring, causing the limit wedge to disengage from the limit slot. Only then can the operator move the fixed column.

[0006] This utility model provides a corrosion-resistant liquid level monitoring device, specifically comprising: a float body; a first flange pipe fixedly connected to the lower part of the float body; a second flange pipe fixedly connected to the upper part of the float body; the second flange pipe and the first flange pipe being aligned; a flap box fixedly connected to the front part of the float body; a magnetic float slidably connected inside the float body; a pipe sealing plate fixedly connected to the top surface of the float body; a fixing ring fixedly connected to the bottom surface of the float body; a mounting plate provided below the fixing ring; a drain valve bolted to the center of the bottom surface of the mounting plate; a protective shell fixedly connected to the top surface of the fixing ring; and a support frame fixedly connected to the top surface of the protective shell.

[0007] Furthermore, a mounting post is fixedly connected to the center of the magnetic float; multiple sets of buffer springs are fixedly connected to the outside of the mounting post in a circular array; the ends of the multiple sets of buffer springs are all fixedly connected to the inner wall of the magnetic float.

[0008] Furthermore, a guide ring is slidably connected to the top surface of the fixed ring; a control gear ring is fixedly connected to the top surface of the guide ring; a fixed post is fixedly connected to the top surface of the control gear ring; a guide groove is provided on the top surface of the protective shell; and the fixed post is slidably connected within the guide groove.

[0009] Furthermore, the outer surface of the control gear ring is meshed with multiple sets of transmission gears in a ring array; the top surface of the fixed ring is rotatably connected to multiple sets of transmission shafts in a ring array; the multiple sets of transmission gears are respectively coaxially fixedly connected to the outer surface of the multiple sets of transmission shafts.

[0010] Furthermore, the top surfaces of the multiple sets of transmission shafts are all coaxially fixedly connected with locking brackets; the top surface of the mounting plate is fixedly connected with multiple sets of locking seats in a ring array; the multiple sets of locking seats are all inserted into the fixing ring; the multiple sets of locking brackets are respectively locked into the multiple sets of locking seats.

[0011] Furthermore, a control lever is fixedly connected to the top surface of the fixed column; an auxiliary slider is slidably connected to the rear of the control lever; a fixed plate is fixedly connected to the rear of the fixed ring; the fixed plate is aligned with the position of the control lever; multiple sets of connecting springs are fixedly connected to the front of the fixed plate; the ends of the multiple sets of connecting springs are all fixedly connected to the rear end face of the auxiliary slider.

[0012] Furthermore, a limit slot is provided on the top surface of the control lever; an auxiliary slide is slidably connected inside the support frame; a support spring is fixedly connected to the upper part of the auxiliary slide; the end of the support spring is fixedly connected to the top surface of the support frame; a limit wedge is fixedly connected to the bottom surface of the auxiliary slide; the limit wedge is inserted into the limit slot.

[0013] Furthermore, an impact block is fixedly connected to the upper part of the magnetic float; a pressure switch is fixedly connected to the bottom end face of the tube sealing plate; the pressure switch is aligned with the position of the impact block; an alarm is bolted to the top end face of the tube sealing plate; the alarm is electrically connected to the pressure switch.

[0014] Beneficial effects

[0015] When the liquid level of chemicals fluctuates, this invention uses the elastic potential energy of the buffer spring to buffer the irregular impact force of the liquid on the magnetic float, preventing the magnetic float from shaking violently with the flow of chemicals and maintaining it in a relatively stable state. This ensures that the flap box can accurately reflect the real changes in liquid level, guaranteeing the accuracy of liquid level monitoring. At the same time, it reduces the collision between the magnetic float and the main tube wall of the float cylinder, extending the service life of the magnetic float and effectively improving the practicality of the liquid level monitoring device.

[0016] When the magnetic float floats too high, the impact block will squeeze the pressure switch, causing the pressure switch to activate the alarm and alert the staff that the liquid level in the chemical storage tank is too high. This allows the staff to take measures in advance to prevent liquid from overflowing the container, thus preventing chemical spills and waste, reducing production costs and environmental risks, and further improving the practicality of the liquid level monitoring device.

[0017] When cleaning the accumulated impurities at the bottom of the liquid level monitoring device, the operator only needs to move the fixed column, causing it to slide along the guide groove and rotate the control gear ring. This rotates the transmission gear meshing with it, and through the transmission shaft, it causes the locking bracket to flip. As the locking bracket flips, it disengages from the locking seat, allowing the operator to remove the mounting plate and drain valve. The operation is simple and quick, facilitating rapid drainage and ensuring the accuracy of the liquid level gauge. The quick removal of the mounting plate and drain valve also allows for rapid drainage, enabling the liquid level gauge to return to normal operation more quickly, reducing downtime for equipment maintenance, improving production efficiency, and facilitating inspection and repair of the internal components of the liquid level gauge. This effectively enhances the convenience of the liquid level monitoring device.

[0018] In the initial state, the limit wedge is inserted into the limit slot to limit the control block, preventing the fixed column from sliding accidentally and ensuring the fixing effect between the fixed ring and the mounting plate. When it is necessary to move the control block, simply pull the auxiliary slide to disengage the limit wedge from the limit slot. Only then can the operator move the fixed column, effectively ensuring the stability of the liquid level monitoring device and ensuring the effectiveness of the liquid level monitoring device.

[0033] Example 1:

[0034] This utility model provides a corrosion-resistant liquid level monitoring device. Please refer to [reference needed]. Figures 1 to 9 As shown, it includes: pontoon body 1;

[0035] A first flange pipe 101 is fixedly connected to the lower part of the float body 1; a second flange pipe 102 is fixedly connected to the upper part of the float body 1; the second flange pipe 102 is aligned with the first flange pipe 101; a flap box 103 is fixedly connected to the front part of the float body 1; a magnetic float 104 is slidably connected inside the float body 1; a pipe sealing plate 109 is fixedly connected to the top surface of the float body 1; a fixing ring 111 is fixedly connected to the bottom surface of the float body 1; an mounting plate 112 is provided at the lower part of the fixing ring 111; a drain valve 113 is bolted to the center of the bottom surface of the mounting plate 112; a protective shell 120 is fixedly connected to the top surface of the fixing ring 111; a support frame 127 is fixedly connected to the top surface of the protective shell 120.

[0036] The magnetic float 104 is centrally connected to a mounting post 105; multiple sets of buffer springs 106 are fixedly connected to the outside of the mounting post 105 in a ring array; the ends of the multiple sets of buffer springs 106 are all fixedly connected to the inner wall of the magnetic float 104.

[0037] Among them, a guide ring 114 is slidably connected to the top surface of the fixed ring 111; a control gear ring 115 is fixedly connected to the top surface of the guide ring 114; a fixed post 121 is fixedly connected to the top surface of the control gear ring 115; a guide groove 123 is opened on the top surface of the protective shell 120; and the fixed post 121 is slidably connected in the guide groove 123.

[0038] Among them, the outer side of the control gear ring 115 is meshed with multiple sets of transmission gears 117 in a ring array; the top surface of the fixed ring 111 is rotatably connected to multiple sets of transmission shafts 116 in a ring array; the multiple sets of transmission gears 117 are respectively coaxially fixedly connected to the outer side of the multiple sets of transmission shafts 116.

[0039] Among them, the top surfaces of multiple sets of transmission shafts 116 are all coaxially fixedly connected with locking brackets 118; the top surface of the mounting plate 112 is fixedly connected with multiple sets of locking seats 119 in a ring array; the multiple sets of locking seats 119 are all inserted into the fixing ring 111; the multiple sets of locking brackets 118 are respectively locked into the multiple sets of locking seats 119.

[0040] Among them, a control block 122 is fixedly connected to the top surface of the fixed column 121; an auxiliary slider 126 is slidably connected to the rear part of the control block 122; a fixed plate 124 is fixedly connected to the rear part of the fixed ring 111; the fixed plate 124 is aligned with the position of the control block 122; multiple sets of connecting springs 125 are fixedly connected to the front part of the fixed plate 124; the ends of the multiple sets of connecting springs 125 are all fixedly connected to the rear end face of the auxiliary slider 126.

[0041] The top surface of the control lever 122 has a limit slot 131; an auxiliary slide 128 is slidably connected inside the support frame 127; a support spring 129 is fixedly connected to the upper part of the auxiliary slide 128; the end of the support spring 129 is fixedly connected to the top surface of the support frame 127; a limit wedge 130 is fixedly connected to the bottom surface of the auxiliary slide 128; the limit wedge 130 is inserted into the limit slot 131.

[0042] The specific usage and function of this embodiment are as follows: When monitoring the liquid level of chemicals, the first flange pipe 101 and the second flange pipe 102 are fixed to the flanges pre-installed on the chemical storage tank using bolts. The liquid level monitoring device is then installed on the chemical storage tank. Simultaneously, the float body 1, the interior of the first flange pipe 101 and the second flange pipe 102, and the exterior of the magnetic float 104 are all coated with a corrosion-resistant coating to prevent corrosion of the liquid level monitoring device by chemicals, thus extending its service life. After the liquid level monitoring device is installed, the pressure inside the chemical storage tank is the same as the pressure inside the float body 1, causing the chemicals in the chemical storage tank to flow into the float body 1 through the first flange pipe 101. As the chemical level changes, the liquid level... The moving magnetic float 104 slides within the float body 1, and its own magnetism causes the flapper plate in the flapper box 103, which is at the same height as the magnetic float 104, to flip, thus displaying the liquid level in the chemical storage tank. Simultaneously, when the liquid level fluctuates, the magnetic float 104 experiences irregular impacts from the liquid. The elastic potential energy of the buffer spring 106 within the magnetic float 104 buffers these irregular impacts, preventing the magnetic float 104 from shaking violently with the flow of chemicals. This also reduces collisions between the magnetic float 104 and the wall of the float body 1, extending the service life of the magnetic float 104. The drain valve 113 removes contaminants from the float body 1. During cleaning, when removing accumulated impurities from the bottom of the liquid level monitoring device, the operator simply moves the fixed column 121, causing it to slide along the guide groove 123. This sliding motion of the fixed column 121 rotates the control gear ring 115. The rotation of the control gear ring 115 also causes the guide ring 114 to slide within the fixed ring 111, providing guidance for the control gear ring 115. The rotation of the control gear ring 115 further drives the meshing transmission gear 117 to rotate, which in turn drives the transmission shaft 116 to rotate. This rotation of the transmission shaft 116 causes the locking bracket 118 to flip, thus reversing the locking bracket 118. After detaching from the locking seat 119, the operator can remove the mounting plate 112 and the drain valve 113. During the sliding of the fixing post 121, the control block 122 will move. This movement causes the auxiliary slider 126 to slide within the control block 122 and compress the connecting spring 125. The elastic potential energy of the connecting spring 125 provides a good reset for the control block 122. In the initial state, the limiting wedge 130 is inserted into the limiting slot 131 to limit the control block 122, preventing accidental sliding of the fixing post 121 and ensuring the fixing effect between the fixing ring 111 and the mounting plate 112. When it is necessary to move the control block 122, the operator only needs to pull the auxiliary slide 128.The auxiliary slide 128 moves the limiting wedge 130, compressing the support spring 129 and causing the limiting wedge 130 to disengage from the limiting slot 131. Only then can the operator move the fixing column 121 to prevent accidental sliding of the fixing column 121 during the use of the liquid level monitoring device, thus avoiding the accidental detachment of the drain valve 113.

[0043] Example 2:

[0044] Based on Example 1, please refer to Figures 1 to 9 As shown, it includes: an impact block 107, a pressure switch 108, and an alarm 110. The impact block 107 is fixedly connected to the upper part of the magnetic float 104; the pressure switch 108 is fixedly connected to the bottom end face of the pipe sealing plate 109; the pressure switch 108 is aligned with the impact block 107; an alarm 110 is bolted to the top end face of the pipe sealing plate 109; the alarm 110 is electrically connected to the pressure switch 108.

[0045] The specific usage and function of this embodiment: In this utility model, as the liquid level in the storage tank rises continuously, the magnetic float 104 will float upward. When the floating height of the magnetic float 104 is too high, the impact block 107 will squeeze the pressure switch 108. After the pressure switch 108 is squeezed, the pressure switch 108 will activate the alarm 110 to warn the staff that the liquid level in the chemical storage tank is too high. The pressure switch 108 and the control circuit connection between the pressure switch 108 and the alarm 110 described in this application to control the alarm 110 are all technical means commonly used by those skilled in the art, so they will not be described in detail here.
