Description

Technical Field

[0001] This application relates to the field of phosphate equipment technology, and in particular to a liquid level detection structure for a slurry tank container. Background Technology

[0002] In mineral processing and grinding, slurry or feedstock is typically stored, stirred, or transported in enclosed tanks as a solid suspension. Real-time and accurate measurement of the tank level is crucial for automated control. Non-contact radar level gauges have become the mainstream measuring instrument in these applications due to their fast response, low maintenance, and ability to measure in high-temperature and high-solid-content environments.

[0003] In existing technologies, radar level gauges are typically installed vertically at the top opening of a slurry tank. Microwave signals are emitted downwards from the instrument, returning to the liquid surface as echoes, which are then processed and converted into the liquid level height. However, when the slurry temperature in the tank is high (usually between 30 and 40°C) and the solids concentration is between 35% and 40%, a dense vapor layer easily forms above it. This vapor layer causes multiple reflections, scattering, and attenuation of the radar microwave signal, resulting in echo signal delays and difficulty in identification, thus leading to significant measurement errors or even complete malfunction of the level gauge.

[0004] A malfunctioning level gauge not only affects the stable operation of the production process, but also requires manual shutdown for cleaning or repeated maintenance and debugging, resulting in a decrease in equipment uptime, an increase in operating costs, and an adverse impact on the automation control of mineral processing and grinding units as well as product quality control. Utility Model Content

[0005] This application provides a liquid level detection structure for a slurry tank container, including: Slurry tank, radar level gauge, exhaust pipe and axial flow fan device; The slurry tank has a closed top structure, which is used to contain the slurry and generate steam during operation; The radar level gauge is vertically installed at the opening at the top of the slurry tank to measure the liquid level in the slurry tank in real time; the exhaust pipe is located at the top of the slurry tank and communicates with the interior of the slurry tank. The exhaust pipe has a diameter of DN400 and a length of 1.5 meters to guide the steam in the slurry tank to rise in a concentrated manner; the axial flow fan is installed at the top of the exhaust pipe to drive the steam out.

[0006] Optionally, the exhaust pipe is connected to the slurry tank via a flange and is equipped with a sealing gasket.

[0007] Optionally, the exhaust pipe includes a vapor buffer section and a main pipe section, the vapor buffer section being located at the bottom of the exhaust pipe, and the cross-sectional area of ​​the vapor buffer section being larger than that of the main pipe section.

[0015] As can be seen from the above technical solutions, this application has the following advantages: 1. By setting up an exhaust pipe and equipping it with an axial flow fan, the steam generated in the slurry tank is concentrated and quickly discharged, effectively preventing the steam from accumulating in the tank and preventing it from reflecting, attenuating and diffusing the radar level gauge signal, thereby significantly improving the measurement accuracy and stability of the radar level gauge.

[0016] 2. This invention reduces frequent malfunctions and maintenance of radar level gauges caused by steam interference by controlling steam emissions, thus lowering the equipment's maintenance frequency. Compared to traditional methods, the operating time of the level gauge is significantly extended, greatly improving the equipment's efficiency and reliability, and reducing manual intervention and downtime.

[0017] 3. The exhaust pipe and axial fan device have a simple design structure, low implementation cost, and convenient maintenance.

Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0025] See Figure 1 as well as Figure 2 A liquid level detection structure for a slurry tank container, characterized in that it comprises: Slurry tank 01, radar level gauge 02, exhaust pipe 03, and axial flow fan device 04; The slurry tank 01 is a top-closed structure used to contain slurry and generate steam during operation; The radar level gauge 02 is vertically installed at the opening on the top of the slurry tank 01 to measure the liquid level in the slurry tank 01 in real time; the exhaust pipe 03 is located on the top of the slurry tank 01 and communicates with the interior of the slurry tank 01. The exhaust pipe 03 has a diameter of DN400 and a length of 1.5 meters to guide the steam in the slurry tank 01 to rise in a concentrated manner; the axial flow fan device 04 is installed on the top of the exhaust pipe 03 to drive the steam to be discharged.

[0026] This application first provides an embodiment of a liquid level detection structure for a slurry tank container, including: The slurry tank 01, radar level gauge 02, exhaust pipe 03, and axial flow fan device 04; the slurry tank 01 is a top-closed structure used to contain slurry and generate steam during operation; Radar level gauge 02 is vertically installed at the opening on the top of slurry tank 01 to measure the liquid level in slurry tank 01 in real time; exhaust pipe 03 is set at the top of slurry tank 01 and connected to the inside of slurry tank 01. The diameter of exhaust pipe 03 is DN400 and the length is 1.5 meters, which is used to guide the steam in slurry tank 01 to rise in a concentrated manner; axial flow fan device 04 is installed at the top of exhaust pipe 03 to drive the steam to be discharged.

[0027] This embodiment provides a liquid level detection structure for a slurry tank container, including a slurry tank 01, a radar level gauge 02, an exhaust pipe 03, and an axial flow fan device 04.

[0028] The slurry tank 01 is a top-closed structure used to hold slurry. During operation, it generates a large amount of high-temperature steam due to material stirring, heating, or reaction. To ensure the accuracy of liquid level detection and prevent steam accumulation from affecting equipment operation, corresponding exhaust channels and forced ventilation structures are provided.

[0029] The radar level gauge 02 is vertically installed at the opening on the top of the slurry tank 01. Utilizing a non-contact electromagnetic wave ranging principle, it can accurately measure the liquid level in the slurry tank 01 in real time, making it particularly suitable for environments with high dust, high humidity, and corrosive gases. The radar level gauge 02 is preferably installed away from the main steam emission path to avoid interference from hot air fluctuations and condensation backflow.

[0030] Exhaust pipe 03 is located at the top of slurry tank 01 and connects to the inside of the tank, providing a centralized outlet for steam inside the tank. The diameter of exhaust pipe 03 is set to DN400 and the length is 1.5 meters. This size and structure guide the steam upward in a directional manner while ensuring that the airflow has a certain inertia and velocity, thereby reducing the lateral diffusion of steam on the top surface of the tank and reducing the impact on the operation of the level gauge.

[0031] To further enhance steam discharge capacity, an axial flow fan device 04 is installed at the top of the exhaust duct 03. During operation, the axial flow fan device 04 generates an upward suction airflow, which rapidly discharges the steam generated in the tank, preventing condensation contamination, equipment corrosion, and measurement errors caused by steam stagnation. The fan structure was selected with consideration for corrosion resistance and high-temperature resistance to meet the requirements of long-term continuous operation.

[0032] More preferably, the exhaust pipe 03 is made of corrosion-resistant material and may have a hydrophobic coating inside to reduce the adhesion or dripping of water droplets formed by steam condensation, thereby extending the service life of the equipment and improving the stability of the system.

[0033] Through the above structural design, this embodiment can effectively guide and discharge the high-temperature steam generated in the slurry tank 01, significantly reduce the interference of steam on the detection signal of the radar level gauge 02, and improve the accuracy of level measurement and the reliability of system operation.

[0034] In an optional embodiment, the exhaust pipe 03 is connected to the slurry tank 01 via a flange and is equipped with a sealing gasket.

[0035] In an optional embodiment, the exhaust pipe 03 and the slurry tank 01 are connected by a flange, and a sealing gasket is provided at the connection to improve the structural sealing performance and prevent steam leakage at the connection interface. This flange connection method facilitates the disassembly and maintenance of the exhaust pipe 03, and by using a high-temperature and corrosion-resistant sealing gasket, it can effectively meet the sealing requirements under high-temperature and high-humidity conditions, enhancing the reliability of the connection.

[0036] Alternatively, the flange may employ a standard circular split design and be secured with bolts. The sealing gaskets are preferably made of PTFE, silicone rubber, or graphite composite materials to ensure good compression resilience and resistance to media erosion during long-term operation. This configuration not only ensures the sealing integrity of the venting path but also reduces safety hazards caused by seal failure during maintenance.

[0037] The above improvements enable the slurry tank 01 to provide better sealing performance in the high temperature and high pressure operating environment, reduce energy loss and environmental pollution during equipment operation, and help extend the overall life of the system and improve operational stability.

[0038] In an optional embodiment, the exhaust duct 03 includes a vapor buffer section 05 and a main pipe section 06. The vapor buffer section is located at the bottom of the exhaust duct 03, and the cross-sectional area of ​​the vapor buffer section 05 is larger than that of the main pipe section 06.

[0039] In an optional embodiment, the exhaust pipe 03 includes a steam buffer chamber section and a main pipe section 06, wherein the steam buffer chamber section is located at the bottom of the exhaust pipe 03, near the connection end of the slurry tank 01; the cross-sectional area of ​​the steam buffer chamber section is larger than the cross-sectional area of ​​the main pipe section 06. This structural design aims to provide a larger buffer zone when steam initially enters the exhaust channel, thereby slowing down the steam flow rate and turbulence intensity, reducing its interference with the radar level gauge 02, and improving the stability and accuracy of level measurement.

[0040] Furthermore, the steam buffer chamber section can adopt a short cylindrical or conical structure, and guide vanes or anti-splash nets can be installed inside to optimize the steam flow trajectory and prevent high-speed steam carrying droplets from directly impacting the level gauge waveguide probe. The main pipe section 06 is an exhaust channel extending to the connection of the fan device, preferably a cylindrical pipe of uniform diameter, to maintain the flow stability of steam during its ascent.

[0041] By designing a buffer chamber with a larger cross-section, the pressure pulse diffusion during the initial concentrated release of steam is facilitated, while also creating conditions for subsequent directional drainage. This significantly improves the reliability and anti-interference capability of the entire liquid level detection system under complex hot and humid environments. This structural optimization is suitable for slurry processing scenarios characterized by high temperature and humidity and fluctuating steam loads.

[0042] In an optional embodiment, the exhaust pipe 03 is provided with turbulence blades, which are arranged in a spiral shape to guide steam to rise along a spiral path.

[0043] In an optional embodiment, the exhaust pipe 03 is equipped with turbulence-inducing blades arranged in a spiral pattern to guide steam upwards along a spiral path. This structural design artificially guides the steam flow direction, altering the velocity and pressure distribution of the steam within the pipe, thereby stabilizing the flow, reducing turbulence, and improving the steam rising efficiency.

[0044] Specifically, the turbulence-inducing blades can be continuously distributed in a spiral shape along the inner wall of the exhaust pipe 03. The pitch and blade inclination angle can be matched and optimized according to the operating conditions of the slurry tank 01 to achieve a relatively stable spiral upward path for steam in the vertical channel. This spiral path helps the liquid droplets entrained in the steam to be thrown towards the pipe wall under the action of centrifugal force, thereby condensing and falling back, reducing the impact of water vapor on the electronic components of the upper radar level gauge 02, and effectively improving the reflectivity and recognition accuracy of the radar measurement signal.

[0045] In addition, the spiral turbulence structure can also reduce the impact force of the instantaneous concentrated discharge of steam, improve the overall stability and continuity of the exhaust system, and is suitable for slurry processing conditions with high heat load or large fluctuations in evaporation rate, further enhancing the applicability and environmental robustness of the slurry tank container level detection structure of this invention.

[0046] In an optional embodiment, the radar level gauge 02 mounting location is provided with a heat insulation cover 07 to insulate against heat conducted by rising steam in the tank.

[0047] In an optional embodiment, the mounting location of the radar level gauge 02 is provided with a heat insulation cover 07 to isolate the heat conducted by the rising steam in the tank. The heat insulation cover 07 is disposed between the radar level gauge 02 and the top of the slurry tank 01, forming a thermal resistance barrier, effectively preventing the steam from conducting high temperature to the radar level gauge 02 body through metal connecting parts or direct convection, thereby ensuring the long-term stable operation of the radar level gauge 02 in high temperature and high humidity environments.

[0048] The heat insulation cover 07 can be made of heat insulation materials with low thermal conductivity, such as foam ceramics, aluminosilicate fiber felt, or composite heat insulation layer structures. It has both good thermal resistance performance and corrosion resistance and high humidity resistance, which is suitable for the use of the slurry tank 01 in strong acid and alkali, high temperature and high steam environment. The heat insulation cover 07 can be in the form of a sleeve type, shell type or multi-layer partition structure, and a heat conduction partition or air gap can be added inside the cover to further enhance the heat insulation effect.

[0049] By setting up the heat insulation cover 07, the measurement error caused by heat aging or heat drift of electronic components in the radar level gauge 02 can be significantly delayed, thereby improving the stability and lifespan of level detection and enhancing the practical applicability and reliability of the structure of the present invention in complex mining production environments.

[0050] In an optional embodiment, the top of the slurry tank 01 is provided with an annular steam guide plate 08, located around the radar level gauge 02, to shield the lateral diffusion direction of the rising steam.

[0051] In an optional embodiment, an annular steam guide plate 08 is provided on the top of the slurry tank 01. The annular steam guide plate 08 is arranged around the installation location of the radar level gauge 02 to shield the lateral diffusion path of rising steam in the top space. The steam guide plate is generally annular or composed of multiple segments forming an annular structure. Its inner diameter is slightly larger than the diameter of the installation opening of the radar level gauge 02, and its outer edge covers part of the top space, so that the steam rising from the inside of the tank preferentially enters the exhaust pipe 03 in the vertical direction, thereby reducing the lateral disturbance of steam around the radar level gauge 02.

[0052] The steam guide plate can be made of high-temperature resistant and corrosion-resistant stainless steel or composite materials, with a moderate thickness to balance structural strength and space arrangement. It can be installed by screwing, welding, or clip-on fixing for easy maintenance and disassembly. The lower edge of the steam guide plate maintains a safe distance from the liquid surface to avoid contact contamination caused by liquid fluctuations, while ensuring the stability of the steam guiding function.

[0053] By setting an annular steam guide plate 08 around the radar level gauge 02, the steam flow path can be effectively controlled, avoiding a large amount of steam from directly impacting the radar probe or generating multi-directional turbulence, improving the reflection accuracy and measurement stability of the level signal, and further enhancing the anti-interference capability and adaptability of the slurry tank container level detection structure in a high steam environment.

[0054] In an optional embodiment, the outer wall of the exhaust pipe 03 is provided with an insulation layer to reduce the possibility of steam condensing when it encounters cold air during its ascent.

[0055] In an optional embodiment, the outer wall of the exhaust pipe 03 is provided with an insulation layer to reduce the risk of condensation of steam due to temperature differences during its ascent. The insulation layer covers the outer surface of the exhaust pipe 03, extending from the connection between the exhaust pipe 03 and the slurry tank 01 to the area near the axial fan device 04, ensuring that the steam remains in a relatively constant temperature environment throughout its passage through the exhaust path.

[0056] The insulation layer can be made of polyurethane foam, aluminum silicate fiber felt, rock wool, or other materials with good thermal insulation properties, and covered with aluminum foil or stainless steel protective plates to improve mechanical strength and weather resistance. The thickness of the insulation layer is determined according to the on-site temperature gradient and steam characteristics, and is usually controlled between 30mm and 80mm to ensure the thermal insulation effect while avoiding excessive increase in the weight or volume of the pipeline.

[0057] By setting up an insulation layer, it is possible to effectively prevent steam from condensing into water prematurely due to cooling during the exhaust process, avoid the accumulation of condensate on the inner wall of the pipe causing blockage or backflow, improve exhaust efficiency and measurement stability of radar level gauge 02, and thus enhance the reliability and service life of the overall slurry tank container level detection system.

[0058] In an optional embodiment, the top of the exhaust duct 03 is provided with a rain cover or a dust cover.

[0059] In an optional embodiment, the top of the exhaust pipe 03 is provided with a rain cover or dust cover to prevent external rainwater, dust and other impurities from entering the exhaust system and to ensure the smooth and clean steam discharge passage.

[0060] The rain cover can be designed in an arched, conical, or umbrella shape, covering the exhaust pipe 03 outlet with a gap between its edge and the exhaust pipe 03 to allow steam to escape smoothly without condensation. The rain cover is preferably made of highly corrosion-resistant metal materials or engineering plastics to withstand the high humidity, high temperature, and corrosive gas conditions of the slurry tank 01 operating environment.

[0061] Dustproof mesh covers can be made of metal woven mesh, stainless steel filter mesh, or high-strength, high-temperature resistant plastic mesh covers. The selection of their aperture should take into account both air circulation and particle isolation effect to prevent dust, foreign objects, or small animals from entering the slurry tank 01 system through the top of the exhaust pipe 03, interfering with the level gauge measurement, or blocking the steam emission path.

[0062] By setting up the above-mentioned protective structure, the environmental adaptability and operational reliability of the exhaust system can be significantly improved, the system maintenance cycle can be extended, and the overall slurry tank 01 liquid level detection structure can be further improved in industrial environments for safety and stability.

[0063] In an optional embodiment, the top of the exhaust duct 03 is provided with an openable observation window 09, the outside of which is covered with a high-temperature resistant transparent material.

[0064] In an optional embodiment, the top of the exhaust pipe 03 is provided with an openable observation window 09, the outside of which is covered with a high-temperature resistant transparent material, so as to facilitate the operator to visually inspect the steam flow status, condensation, or foreign object blockage inside the pipe without disassembling the exhaust device.

[0065] The observation window 09 is preferably located on the wall of the exhaust duct 03 below or to the side of the axial fan device 04. It has a flip-up or detachable structure for easy opening and inspection during maintenance or repair. The transparent material covering the outside of the window can be high-temperature resistant glass, quartz glass, or high-strength transparent polyimide film, etc., and must have good thermal shock resistance and corrosion resistance to adapt to working environments such as high-temperature steam and corrosive gases.

[0066] The setting of the observation window 09 not only improves the convenience of maintenance and the efficiency of inspection, but also helps to detect abnormalities in a timely manner during operation, enabling rapid response and handling of the system's operating status, and further enhancing the practicality and safety assurance capability of the slurry tank container level detection structure of this invention.

[0067] In an optional embodiment, the exhaust duct 03 is provided with a 500 mm long flexible corrugated compensation section at the horizontal corner.

[0068] In an optional embodiment, the exhaust duct 03 is provided with a 500 mm long flexible corrugated compensation section at the horizontal corner to accommodate thermal expansion, contraction, or mechanical vibration that may occur during the installation or operation of the exhaust duct 03. This flexible corrugated compensation section, through its corrugated shape design, can effectively absorb deformation of the duct caused by temperature changes or external forces, ensuring the stability and durability of the exhaust duct 03 system.

[0069] The flexible corrugated compensation section is preferably made of high-temperature resistant, non-aging synthetic rubber or metal alloy materials, possessing excellent compressive strength, tensile strength, and corrosion resistance to meet the usage requirements of the exhaust pipe 03 system in high-temperature and high-humidity environments. The flexible corrugated compensation section ensures that pipe connections will not leak or be damaged due to temperature changes under different operating conditions, further improving the sealing and reliability of the exhaust system.

[0070] By setting up this flexible corrugated compensation section, this embodiment effectively avoids structural deformation or cracking caused by excessive stress on the pipeline, improves the durability and safety of the entire slurry tank container level detection structure, reduces downtime for maintenance due to equipment failure, and extends the service life of the equipment.
