Description

Technical Field

[0001] This utility model relates to the field of acid tank technology, and more specifically, to a level gauge mounting bracket. Background Technology

[0002] In the production of feed-grade phosphoric acid, the acid mixing tank is a key piece of equipment. The internal temperature of the phosphoric acid is typically between 60 and 80°C. When phosphoric acid enters the acid mixing tank, it generates a large amount of high-temperature acid mist. In the liquid level measurement stage, radar level gauges are widely used due to their advantages such as high accuracy and non-contact operation.

[0003] Previously, radar level gauges were often directly plugged into the opening of the acid mixing tank. However, this installation method has significant drawbacks. High-temperature acid mist permeates the acid mixing tank, and upon encountering the relatively cool tank walls and the level gauge, it quickly condenses and forms scale. This scale easily adheres to the radar level gauge probe, causing frequent display errors. This not only affects the accurate monitoring of the acid mixing tank level during production but also necessitates frequent disassembly and cleaning of the level gauge, increasing maintenance costs and labor intensity. Furthermore, it can potentially lead to production safety hazards due to erroneous level monitoring.

[0004] To address the aforementioned issues, while some attempts have been made to improve the system by adding a simple bracket to the opening of the acid mixing tank and mounting the radar level gauge on top of the bracket, allowing acid mist to escape through the gaps in the bracket and reducing direct contact with the level gauge probe to avoid scaling, these simple brackets still fall short in terms of height adjustment flexibility, structural stability, and overall protection against high-temperature acid mist. They cannot meet the stringent requirements for high-precision, stable level measurement in feed-grade phosphoric acid production. For example, patent CN210221199U discloses a bracket for mounting a level gauge on an open container. This bracket includes a vertical first support rod with a short sleeve fixed parallel to it. A vertical rotating shaft runs through the inside of the short sleeve, and a second support rod perpendicular to it, used to fix the level gauge, is fixedly connected to the top of the vertical rotating shaft. The vertical rotating shaft and the short sleeve are connected by locking bolts and locking nuts. While this bracket facilitates instrument inspection and maintenance to some extent, its height adjustment structure is relatively complex when applied to feed-grade phosphate mixing tanks. It also cannot effectively cope with the corrosion problem caused by high-temperature acid mist inside the mixing tank. In terms of structural stability, it is difficult to adapt to the vibration and other working conditions that may exist in the mixing tank. Therefore, it cannot ensure that the radar level gauge can measure the liquid level stably and accurately in harsh environments for a long time. Utility Model Content

[0005] The purpose of this utility model is to provide a liquid level gauge mounting bracket to solve the problem mentioned in the background art that scale can easily adhere to the radar liquid level gauge probe, causing the liquid level gauge to frequently display errors. This not only affects the accurate monitoring of the liquid level in the acid mixing tank during production, but also requires frequent disassembly and cleaning of the liquid level gauge, increasing maintenance costs and labor intensity. In addition, it may also cause production safety hazards due to liquid level monitoring errors.

[0006] To achieve the above objectives, this utility model provides a liquid level gauge mounting bracket, including a lifting base on which a radar liquid level gauge is mounted. The lifting base is supported and its height is adjustable by an adjustable bracket, which is installed on the opening of an acid mixing tank. The adjustable bracket includes a fixing ring, and threaded rods are installed on the top of both sides of the fixing ring. Adjusting nuts are threaded onto the threaded rods, and an adjusting plate passes through the threaded rods. The lifting base is mounted on the adjusting plate, and the adjusting plate slides vertically with the threaded rods. The height of the adjusting plate is adjusted by raising and lowering the adjusting nuts.

[0007] This setup forms the overall structure of the level gauge mounting bracket. The lifting seat supports the radar level gauge, while the adjustable bracket is the key structure for achieving support and height adjustment. The fixing ring is installed on the opening of the acid tank, serving a basic positioning function. The threaded rods on both sides of the top slide vertically with the adjusting plate, and the adjusting nut is threaded onto the threaded rod. When the adjusting nut is rotated, its position on the threaded rod changes. Because the adjusting plate slides vertically with the threaded rod and is restricted by the adjusting nut, the raising and lowering of the adjusting nut can drive the adjusting plate to move up and down, thereby adjusting the height of the lifting seat and the radar level gauge mounted on the adjusting plate.

[0008] Preferably, the upper side of the radar level gauge is connected to a level gauge wiring device, the lower part of the radar level gauge passes through the lifting base and is equipped with a level gauge probe, and the lower part of the radar level gauge is detachably connected to the through hole in the middle of the lifting base.

[0009] This radar level gauge is connected to an external circuit via wiring to transmit measurement data. The lower part of the level gauge passes through the lifting base and houses the level gauge probe for detecting the liquid level. The lower part is detachably connected to the through-hole in the middle of the lifting base, using common methods such as threaded connections or snap-fit ​​connections, allowing for easy removal of the level gauge from the lifting base in case of malfunction or maintenance.

[0010] Preferably, the lifting seat is connected and fixed to the lifting seat by an upper locking bolt.

[0011] The upper locking bolt is used to securely connect the lifting seat to the adjusting plate. By tightening the upper locking bolt, the lifting seat and the adjusting plate are tightly fitted, limiting the relative displacement between them. This ensures that even when affected by external forces such as liquid fluctuations in the acid tank or equipment vibrations during the operation of the level gauge, the lifting seat can be stably fixed on the adjusting plate.

[0012] Preferably, the fixing ring is installed at the opening of the acid mixing tank by a lower locking bolt.

[0013] This setting involves installing the fixing ring at the opening of the acid mixing tank using a lower locking bolt. The lower locking bolt passes through the mounting hole on the fixing ring and is tightened into the corresponding screw hole at the edge of the opening of the acid mixing tank, thereby firmly fixing the fixing ring to the acid mixing tank.

[0014] Preferably, the lower locking bolts are arranged in a ring at equal intervals on the fixing ring.

[0015] In this design, the lower locking bolts are arranged in a ring at equal intervals on the retaining ring. This layout ensures that the retaining ring experiences uniform tightening force in all directions when installed into the acid tank opening. Tightening each lower locking bolt applies balanced pressure to the retaining ring, firmly pressing it against the edge of the acid tank opening.

[0016] Preferably, the adjustable bracket is equipped with negative pressure fans on both sides near the level gauge probe to extract high-temperature acid mist.

[0017] This setup involves installing negative pressure fans on both sides of an adjustable bracket near the level gauge probe. When the fan is operating, its internal motor drives the impeller to rotate, creating a negative pressure zone inside the fan. The high-temperature acid mist in the acid mixing tank is drawn into the negative pressure fan under the pressure difference and discharged outside the tank through the fan's outlet.

[0018] Preferably, a sealing ring is provided between the lower part of the radar level gauge and the through hole in the middle of the lifting seat. The sealing ring is sleeved on the lower part of the radar level gauge, and an annular groove that mates with the sealing ring is provided on the inner wall of the through hole to enhance the sealing of the connection.

[0019] This feature includes a sealing ring installed between the lower part of the radar level gauge and the through hole in the middle of the lifting base. The sealing ring is fitted onto the lower part of the radar level gauge, and the inner wall of the through hole has an annular groove that mates with the sealing ring. When the radar level gauge is installed on the lifting base, the sealing ring is pressed between the outer wall of the radar level gauge and the annular groove. The elastic deformation of the sealing ring fills the gap between the two, preventing acid mist from entering from this connection point.

[0020] Preferably, the threaded rod is provided with vertical scale lines.

[0021] This feature involves vertically aligned graduations on the threaded rod, with the graduations evenly spaced according to the rod's length. As the adjusting nut moves along the threaded rod, the operator can visually monitor the height changes of the adjusting plate and the level gauge mounted on it by observing the corresponding graduation values.

[0022] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0023] In this level gauge mounting bracket, negative pressure fans are installed on both sides of the adjustable bracket near the level gauge probe. These fans can promptly extract the high-temperature acid mist generated in the acid mixing tank, greatly reducing the accumulation of acid mist near the level gauge probe. At the same time, a sealing ring and annular groove are installed between the lower part of the radar level gauge and the through hole in the middle of the lifting base. This enhances the sealing of the connection, prevents acid mist intrusion, and effectively avoids the condensation of high-temperature acid mist onto the level gauge probe. This ensures the accuracy and stability of the level gauge measurement, reduces display errors caused by scaling, and lowers maintenance frequency and costs.

[0024] The lifting seat is supported and height-adjustable by an adjustable bracket. Threaded rods are installed on the top of both sides of the fixing ring of the adjustable bracket. The adjusting plate slides vertically with the threaded rods, and the height of the adjusting plate can be easily adjusted by raising or lowering the adjusting nut. This allows for adjustment of the height of the lifting seat and radar level gauge mounted on the adjusting plate. Furthermore, vertical graduations are set on the threaded rods, making the height adjustment process more intuitive and precise. This enables quick and accurate adjustment of the level gauge height according to different operating conditions of the acid mixing tank, meeting the high-precision level measurement requirements in feed-grade phosphoric acid production.

[0025] The fixing ring is installed at the opening of the acid mixing tank by the lower locking bolts, which are arranged in a ring at equal intervals on the fixing ring. This installation method ensures a tight connection between the fixing ring and the acid mixing tank, enhancing the stability of the entire mounting bracket. The lifting seat is connected and fixed to the adjusting plate by the upper locking bolts, further ensuring the stability of the radar level gauge installation. It can effectively resist the influence of vibration and other working conditions that may exist in the acid mixing tank, ensuring that the level gauge can work stably for a long time in harsh environments.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] This utility model provides a liquid level gauge mounting bracket, such as Figures 1-3 As shown, the system includes a lifting seat 2, on which a radar level gauge 1 is installed. The lifting seat 2 is supported and its height is adjusted by an adjustable bracket 3. The adjustable bracket 3 is installed on the opening 41 of the acid mixing tank 4. The adjustable bracket 3 includes a fixing ring 31. Threaded rods 33 are installed on the top of both sides of the fixing ring 31. Adjusting nuts 331 are threaded onto the threaded rods 33. An adjusting plate 32 passes through the threaded rods 33. The lifting seat 2 is installed on the adjusting plate 32. The adjusting plate 32 and the threaded rods 33 slide vertically together, and the height of the adjusting plate 32 is adjusted by the lifting of the adjusting nuts 331.

[0033] This design establishes the overall structure of the level gauge mounting bracket. The lifting seat 2 supports the radar level gauge 1, while the adjustable bracket 3 is the key structure for support and height adjustment. The fixing ring 31 is installed on the opening 41 of the acid mixing tank 4, serving a basic positioning function. The threaded rods 33 on both sides of the top of the fixing ring 31 slide vertically with the adjusting plate 32. The adjusting nut 331 is threaded onto the threaded rod 33. When the adjusting nut 331 is rotated, its position on the threaded rod 33 changes. Because the adjusting plate 32 slides vertically with the threaded rod 33 and is restricted by the adjusting nut 331, the lifting of the adjusting nut 331 can drive the adjusting plate 32 to move up and down, thereby adjusting the height of the lifting seat 2 and the radar level gauge 1 mounted on the adjusting plate 32. This design makes the level gauge height adjustment flexible and convenient. Operators can quickly adjust the height of the radar level gauge 1 according to changes in the liquid level in the acid mixing tank 4 and the special requirements for level measurement in different batches of production, ensuring that the level gauge is always in the optimal measurement position, greatly improving the accuracy and adaptability of level measurement.

[0034] In this embodiment, a level gauge wiring 11 is connected to the upper side of the radar level gauge 1, and a level gauge probe 12 is installed at the lower part of the radar level gauge 1 through the lifting seat 2. The lower part of the radar level gauge 1 is detachably connected to the through hole 21 in the middle of the lifting seat 2.

[0035] The radar level gauge 1 connects to an external circuit via the level gauge wiring 11 to transmit measurement data. The lower part of the radar level gauge 1 passes through the lifting base 2 and houses the level gauge probe 12 for detecting the liquid level. The lower part of the radar level gauge 1 is detachably connected to the through hole 21 in the middle of the lifting base 2, using common methods such as threaded connections or snap-fit ​​connections. This allows for easy removal of the level gauge from the lifting base 2 when it malfunctions or requires maintenance. This detachable connection design greatly improves the ease of maintenance of the level gauge, reducing maintenance costs and time. When the level gauge probe 12 experiences scaling or damage, it can be quickly disassembled for cleaning and replacement, minimizing production downtime due to equipment maintenance and ensuring continuous production.

[0036] Specifically, the lifting seat 2 is connected and fixed to the upper locking bolt 34.

[0037] The upper locking bolt 34 is used to securely connect the lifting seat 2 and the adjusting plate 32. By tightening the upper locking bolt 34, the lifting seat 2 and the adjusting plate 32 are tightly fitted together, limiting the relative displacement between them. This ensures that during the operation of the level gauge, even if affected by external forces such as liquid fluctuations in the acid tank 4 or equipment vibration, the lifting seat 2 can be stably fixed on the adjusting plate 32. This enhances the stability of the radar level gauge 1 installation, ensures stable operation of the level gauge under complex working conditions, avoids level gauge position deviation due to loose connection, and thus affects the accuracy of level measurement, effectively improving the reliability of the level measurement system.

[0038] Furthermore, the retaining ring 31 is installed at the opening 41 of the acid mixing tank 4 by the lower locking bolt 311.

[0039] The retaining ring 31 is installed at the opening 41 of the acid mixing tank 4 via a lower locking bolt 311. The lower locking bolt 311 passes through the mounting hole on the retaining ring 31 and is tightened into the corresponding screw hole on the edge of the opening 41 of the acid mixing tank 4, thereby firmly fixing the retaining ring 31 to the acid mixing tank 4. This provides a stable mounting base for the entire adjustable bracket 3 and the radar level gauge 1 mounted on it, enabling it to withstand the weight of the level gauge itself and any external forces that may be applied, ensuring that the level gauge will not shift during the operation of the acid mixing tank 4, and ensuring the accuracy and stability of the level measurement.

[0040] Furthermore, the lower locking bolts 311 are arranged in a ring at equal intervals on the fixing ring 31.

[0041] The lower locking bolts 311 are arranged in a ring at equal intervals on the fixing ring 31. This layout ensures that the fixing ring 31 experiences uniform tightening force in all directions when installed into the opening 41 of the acid mixing tank 4. Tightening each lower locking bolt 311 applies balanced pressure to the fixing ring 31, firmly pressing it against the edge of the opening 41 of the acid mixing tank 4. This further enhances the stability and firmness of the connection between the fixing ring 31 and the acid mixing tank 4. Compared to non-uniformly distributed bolt connections, this arrangement better resists external forces such as vibrations and liquid sloshing that may occur in the acid mixing tank 4, preventing the fixing ring 31 from loosening or shifting, thus providing a reliable guarantee for the stable operation of the level gauge.

[0042] Furthermore, a negative pressure fan 35 for extracting high-temperature acid mist is installed on both sides of the adjustable bracket 3 near the level gauge probe 12.

[0043] Negative pressure fans 35 are installed on both sides of the adjustable bracket 3 near the level gauge probe 12. When the fan is working, its internal motor drives the impeller to rotate, creating a negative pressure area inside the fan. High-temperature acid mist in the acid mixing tank 4 is drawn into the negative pressure fan 35 under the pressure difference and discharged outside the acid mixing tank 4 through the fan's outlet. This effectively reduces the concentration of high-temperature acid mist around the level gauge probe 12, lowers the possibility of acid mist condensation and scale adhering to the probe, greatly improves the accuracy and stability of the level gauge measurement, reduces level gauge display errors caused by acid mist, and lowers maintenance frequency and costs.

[0044] Furthermore, a sealing ring is provided between the lower part of the radar level gauge 1 and the through hole 21 in the middle of the lifting seat 2. The sealing ring is fitted on the lower part of the radar level gauge 1, and an annular groove that mates with the sealing ring is provided on the inner wall of the through hole 21 to enhance the sealing of the connection.

[0045] A sealing ring is installed between the lower part of the radar level gauge 1 and the through hole 21 in the middle of the lifting base 2. The sealing ring is fitted onto the lower part of the radar level gauge 1, and the inner wall of the through hole 21 has an annular groove that mates with the sealing ring. When the radar level gauge 1 is installed on the lifting base 2, the sealing ring is squeezed between the outer wall of the radar level gauge 1 and the annular groove. The elastic deformation of the sealing ring fills the gap between the two, preventing acid mist from entering from this connection point. This significantly enhances the sealing performance of the connection point, further preventing high-temperature acid mist from corroding the internal electronic components of the radar level gauge 1, protecting the normal operation of the level gauge, extending its service life, and also helping to improve the accuracy and stability of level measurement.

[0046] Furthermore, the threaded rod 33 is vertically marked with scale lines.

[0047] A scale is vertically set on the threaded rod 33, with the scale lines evenly spaced according to the length of the threaded rod 33. When the adjusting nut 331 moves on the threaded rod 33, the operator can intuitively understand the height change of the adjusting plate 32 and the level gauge mounted on it by observing the corresponding scale value of the adjusting nut 331. This makes the level gauge height adjustment process more intuitive and precise, allowing the operator to accurately adjust the level gauge to the required height according to actual needs, avoiding measurement errors caused by over- or under-adjustment, and improving the efficiency and accuracy of level gauge height adjustment.

[0048] When using the liquid level gauge mounting bracket of this utility model, first place the fixing ring 31 at the opening 41 of the acid mixing tank 4, and then install it using the lower locking bolt 311. The lower locking bolt 311 passes through the mounting hole on the fixing ring 31 and is tightened with the corresponding screw hole on the edge of the opening 41 of the acid mixing tank 4. Since the lower locking bolts 311 are arranged in a ring with equal spacing on the fixing ring 31, the fixing ring 31 can be evenly stressed in all directions during the tightening process, and is tightly fixed on the acid mixing tank 4, providing a stable foundation for the entire mounting bracket.

[0049] The adjusting plate 32 is passed through the threaded rod 33 to form a vertical sliding fit between the adjusting plate 32 and the threaded rod 33. The lifting seat 2 is then installed on the adjusting plate 32, and the lifting seat 2 and the adjusting plate 32 are firmly connected by the upper locking bolt 34 to limit the relative displacement between the two and ensure that the lifting seat 2 is stably fixed.

[0050] The lower part of the radar level gauge 1 is passed through the central through hole 21 of the lifting base 2. The radar level gauge 1 is installed in place using a detachable connection method (such as threaded connection or snap-fit). A sealing ring is placed at the connection point, fitted onto the lower part of the radar level gauge 1, and engages with the annular groove on the inner wall of the through hole 21 to enhance the sealing of the connection and prevent the intrusion of high-temperature acid mist. Finally, the level gauge wiring 11 is connected to establish communication between the radar level gauge 1 and the external circuit, completing the overall installation.

[0051] When the height of the radar level gauge 1 needs to be adjusted, the operator rotates the adjusting nut 331. Since the adjusting nut 331 is threadedly connected to the threaded rod 33, rotating the adjusting nut 331 changes its position on the threaded rod 33. The adjusting plate 32 is vertically slidingly engaged with the threaded rod 33 and is restricted by the adjusting nut 331. Therefore, the raising and lowering of the adjusting nut 331 causes the adjusting plate 32 to move up and down, thereby adjusting the height of the lifting seat 2 mounted on the adjusting plate 32 and the radar level gauge 1. The vertically set scale lines on the threaded rod 33 provide the operator with a visual height reference, enabling the operator to accurately adjust the radar level gauge 1 to the appropriate height according to actual needs, ensuring that the level gauge is in the optimal measuring position.

[0052] The radar level gauge 1 detects the liquid level in the acid mixing tank 4 through the level gauge probe 12. The detection data is transmitted to the external control system through the level gauge wiring 11, realizing real-time monitoring of the liquid level in the acid mixing tank 4. During the operation of the acid mixing tank 4, a large amount of high-temperature acid mist is generated. At this time, the negative pressure fan 35 installed on both sides of the adjustable bracket 3 near the level gauge probe 12 is started. The internal motor drives the impeller to rotate, creating a negative pressure area inside the fan. Under the action of pressure difference, the high-temperature acid mist in the acid mixing tank 4 is sucked into the negative pressure fan 35 and discharged outside the acid mixing tank 4 through the air outlet, effectively reducing the concentration of high-temperature acid mist around the level gauge probe 12, reducing the possibility of acid mist condensation and scale adhering to the probe, and ensuring the accurate and stable operation of the radar level gauge 1.

[0053] When the radar level gauge 1 malfunctions or the level gauge probe 12 becomes scaled or damaged due to acid mist, the lower part of the radar level gauge 1 is detachably connected to the middle through hole 21 of the lifting base 2. This allows operators to easily remove the radar level gauge 1 from the lifting base 2 for cleaning, repair, or replacement of parts. This design greatly improves maintenance convenience, reduces production downtime caused by equipment maintenance, and ensures production continuity.

[0054] Finally, it should be noted that the electronic components in the radar level gauge 1 and other components in this embodiment are all general standard parts or parts known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods. In the idle part of this device, all the above-mentioned electrical components are connected by wires.

All of these are technologies known in the art.

[0055] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
