Description

Technical Field

[0001] This utility model relates to the technical field of raw material dissolution, storage and transportation equipment, specifically to a multifunctional raw material dissolution, storage and transportation device for agricultural large-particle ammonium sulfate. Background Technology

[0002] Ammonium sulfate, as an important nitrogen fertilizer, plays a crucial role in agricultural production. It effectively promotes crop foliage growth, improves fruit quality and yield, and enhances crop resistance to disasters. It can be widely used as a base fertilizer, top dressing, and seed fertilizer. With the development of agricultural modernization, granular ammonium sulfate, due to its optimized physical properties, releases nutrients more slowly and prolongs its fertilizer effect. It can also be used to produce crop-specific fertilizers or blended fertilizers, and its market prospects are very broad.

[0003] In the production process of large-particle ammonium sulfate, the raw material dissolution, storage, and transportation stages are crucial. However, current related technologies have many shortcomings. For example, Chinese patent document CN101570455A proposes a method for preparing ammonium sulfate granules using organic-inorganic binders. While this method can solve the problem of ammonium sulfate granulation, at the industrial level, there is a lack of suitable production equipment to achieve large-scale batch production. Furthermore, relying solely on screening to handle substandard small particles during production leads to resource waste and fails to fully realize the economic benefits of large-particle ammonium sulfate.

[0004] For example, the granular ammonium sulfate production device disclosed in Chinese patent document CN202020445630 has structures such as a raw material melting tank, a binder dissolving tank, a mixing tank, a granulation tower, and a screening box, which can realize the production of ammonium sulfate granules and the return of unqualified products for reprocessing. However, the device lacks sufficient control over the raw material dissolving efficiency and quality during the raw material dissolving stage. Furthermore, it has limited ability to accurately control the feed amount of different raw materials and dynamically regulate parameters such as solution specific gravity and temperature throughout the entire production process, making it difficult to meet the complex and ever-changing actual production needs.

[0005] Given the limitations of existing technology, there is an urgent need to develop a novel multifunctional raw material dissolution, storage, and transportation device for agricultural large-particle ammonium sulfate. This device aims to improve the efficiency and quality of raw material dissolution, achieve precise control over the feed amount of different raw materials, flexibly and dynamically adjust various parameters of the solution, thereby improving production efficiency, reducing production costs, and enhancing the market competitiveness of the product. Utility Model Content

[0006] The purpose of this utility model is to provide a multifunctional raw material dissolution, storage and transportation device for large-particle ammonium sulfate in agriculture, in order to solve the problems mentioned in the background art, such as insufficient control over the dissolution efficiency and quality of raw materials during the raw material dissolution stage, and limited ability to accurately control the feed amount of different raw materials and dynamically regulate parameters such as solution specific gravity and temperature throughout the entire production process, which makes it difficult to meet the complex and ever-changing actual production needs.

[0007] To achieve the above objectives, this utility model provides a multifunctional raw material dissolution, storage, and transportation device for agricultural large-particle ammonium sulfate, including a raw material tank. A feeding component is connected to one side of the top of the raw material tank, and a condensate drainage system is connected to one side of the bottom of the raw material tank. A condensate pipe, a liquid brine raw material pipe, and a low-pressure steam pipe are connected to the top of the raw material tank. The other side of the raw material tank is connected to two liquid feed pumps through pipelines, and the output end of the liquid feed pumps is connected to an outlet pipe through pipelines.

[0008] This system uses a raw material tank as its core component. A top-mounted feeding unit transports solid raw materials, while a bottom-mounted condensate drainage system discharges condensate generated by steam heating. The top-mounted condensate pipe, liquid brine raw material pipe, and low-pressure steam pipe are used for replenishing solvent, transporting liquid raw materials, and heating / insulating, respectively. Two feed pumps deliver the treated solution to the outlet pipe. All components work together to form a complete system integrating feeding, dissolving, heating, and conveying.

[0009] Preferably, the feeding component includes a solid material feeding bin, a feeding screw feeder, an intermediate storage bin, and a metering screw feeder. The feeding screw feeder is inclined, with its lower end connected to the solid material feeding bin and its upper end connected to the intermediate storage bin. The metering screw feeder is horizontally arranged, with one end connected to the intermediate storage bin and the other end connected to the top of the raw material tank.

[0010] In this feeding component, the solid material feeding bin stores solid raw materials, and the feeding screw feeder is set at an angle, using the rotation of the screw blades to push the raw materials upward and transport them to the intermediate storage bin for temporary storage; the metering screw feeder is set horizontally, and through precise control, it transports the raw materials in the intermediate storage bin to the raw material tank according to the metering, so as to realize the quantitative supply of solid raw materials.

[0011] Preferably, the raw material tank is equipped with a tank level gauge and a raw material tank thermometer. The tank level gauge is an ultrasonic level gauge or a radar level gauge, and the raw material tank thermometer is a platinum resistance thermometer or a thermocouple thermometer.

[0012] This setup uses ultrasonic or radar level gauges for the tank level gauges. These gauges emit ultrasonic or electromagnetic waves, which are reflected off the liquid surface and then the echoes are received. The liquid level is calculated based on the time difference between transmission and reception. The raw material tank temperature gauges use platinum resistance thermometers or thermocouple thermometers. These thermometers utilize the principle that the resistance of a metal conductor or semiconductor changes with temperature, or that a closed circuit formed by two different materials generates a thermoelectric potential, to measure the temperature of the solution in the raw material tank in real time.

[0013] Preferably, an online hydrometer is installed on the pipeline between the raw material tank and the feed pump, and a feed flow meter is installed on the outlet pipe.

[0014] This online hydrometer is based on Archimedes' principle or other physical measurement principles. It calculates the specific gravity of the solution in real time by detecting changes in physical quantities such as pressure and buoyancy of the solution on the sensor. The flow meter on the outlet pipe measures the flow rate of the solution through the pipe using principles such as electromagnetic induction and turbine rotation.

[0015] Preferably, a drain pipe is connected to one side of the bottom of the raw material tank, a drain valve is installed on the drain pipe, and the outlet end of the drain pipe is connected to a waste liquid collection device.

[0016] This feature involves connecting the drain pipe to one side of the bottom of the raw material tank. When the raw material tank needs to be cleaned, repaired, or substandard solutions need to be treated, the drain valve is opened, and under gravity, the residual materials or waste liquid in the raw material tank flows into the waste liquid collection device through the drain pipe.

[0017] Preferably, the raw material tank is equipped with a stirring paddle for breaking large ammonium sulfate raw materials into fine particles. The stirring paddle has multiple dispersing blades distributed circumferentially along the rotation axis and is driven to rotate by a drive motor.

[0018] This setup drives the motor to rotate the agitator shaft of the raw material tank, and the dispersing blades distributed circumferentially along the shaft rotate accordingly. During the rotation, the large particles of ammonium sulfate raw material are impacted and sheared, breaking them down into smaller particles. At the same time, the agitation action of the agitator ensures that the raw material and solvent are fully mixed, accelerating the dissolution process.

[0019] Preferably, an electric regulating valve and a flow meter are installed on the condensate pipe, the liquid brine raw material pipe, and the low-pressure steam pipe, respectively. The electric regulating valve and the flow meter are connected to the control system for precise control of the flow rate of each pipe.

[0020] This system features an electrically operated regulating valve that controls its opening degree via an electrical signal from the control system, thereby regulating the flow rate of fluid in the pipeline. A flow meter monitors the flow rate in the pipeline in real time and feeds the flow data back to the control system. Based on the set parameters and the actual measured flow data, the control system automatically adjusts the opening degree of the electrically operated regulating valve, achieving precise control of the flow rate in each pipeline.

[0021] Preferably, the raw material tank has a double-layer jacket structure, with a steam flow chamber formed between the inner and outer layers. The low-pressure steam pipe is connected to the steam flow chamber and is used to heat and keep the material in the raw material tank warm. The condensate drainage system includes a condensate drain pipe connected to the bottom of the steam flow chamber and a drain valve installed on the condensate drain pipe.

[0022] This design incorporates a double-layered jacket structure for the raw material tank, forming a steam flow chamber. A low-pressure steam pipe introduces steam into the steam flow chamber. As the steam flows within the chamber, it transfers heat to the inner layer of the raw material tank through thermal conduction, heating and insulating the material inside. The condensate drainage system features a condensate trap that automatically identifies steam and condensate. When the steam in the steam flow chamber condenses into water, the condensate trap opens to drain the condensate while preventing steam leakage.

[0023] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0024] In this multifunctional raw material dissolution, storage and transportation device for large-particle ammonium sulfate used in agriculture, the stirring paddle installed in the raw material tank is equipped with dispersing blades, which can break the large-particle ammonium sulfate raw material into fine particles, greatly increasing the contact area between the raw material and the solvent, significantly improving the raw material dissolution efficiency and quality, avoiding the problem of insufficient dissolution caused by excessively large particles, and providing a high-quality and stable raw material solution for subsequent production processes.

[0025] Electric regulating valves and flow meters are installed on the condensate pipe, liquid brine raw material pipe, and low-pressure steam pipe, and all are connected to the control system. This allows for precise control of the flow rate of each pipe according to production needs. Combined with the level gauge, thermometer in the raw material tank, and online hydrometer on the liquid outlet pipe, dynamic monitoring and precise control of parameters such as the level, temperature, and specific gravity of the raw material solution can be achieved, ensuring stable production and meeting complex and ever-changing actual production needs.

[0026] The raw material tank adopts a double-layer jacket structure, with a low-pressure steam pipe connected to the steam flow chamber, which can effectively heat and keep the material in the raw material tank warm, reduce heat loss, and reduce energy consumption. At the same time, the matching condensate drainage system can drain the steam condensate in time, ensuring the continuity and stability of the steam heating effect.

[0027] The unique feeding component design, including a solid material feeding bin, a feeding screw feeder, an intermediate storage bin, and a metering screw feeder, enables metered feeding of solid raw materials. Combined with liquid brine raw material pipes and condensate pipes, it can meet various working modes such as separate solid metering feeding, separate liquid raw material metering feeding, separate solvent metering feeding, and simultaneous feeding of multiple media, greatly improving the applicability and flexibility of the device.

[0033] 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.

[0034] This utility model provides a multifunctional raw material dissolution, storage, and transportation device for agricultural large-particle ammonium sulfate, such as... Figure 1 As shown, it includes a raw material tank 1, a feeding component connected to the top side of the raw material tank 1, a condensate drainage system 6 connected to the bottom side of the raw material tank 1, a condensate pipe 8, a liquid brine raw material pipe 9, and a low-pressure steam pipe 10 connected to the top of the raw material tank 1, and two liquid feed pumps 14 connected to the other side of the raw material tank 1 through pipelines, and the output end of the liquid feed pump 14 connected to the outlet pipe 15 through pipelines.

[0035] The raw material tank 1, as the core component, has a feeding component connected to its top side for conveying solid raw materials, and a condensate drainage system 6 connected to its bottom side to discharge condensate generated by steam heating. The condensate pipe 8, liquid brine raw material pipe 9, and low-pressure steam pipe 10 connected to the top are used for replenishing solvent, conveying liquid raw materials, and heating / insulating, respectively. Two feed pumps 14 connected to the other side of the raw material tank 1 transport the treated solution to the outlet pipe 15. All components work together to form a complete system integrating feeding, dissolving, heating, and conveying. This achieves the basic functional integration of a raw material dissolving, storage, and transportation device, enabling the device to receive various raw materials, heat materials, and output finished solutions. Compared to traditional single-function storage tanks, this greatly expands the application range of the device, reduces the number of equipment required in the production process, and improves production efficiency.

[0036] In this embodiment, as Figure 1 , Figure 2As shown, the feeding components include a solid material feeding bin 2, a feeding screw feeder 3, an intermediate storage bin 4, and a metering screw feeder 5. The feeding screw feeder 3 is inclined, with its lower end connected to the solid material feeding bin 2 and its upper end connected to the intermediate storage bin 4. The metering screw feeder 5 is horizontally set, with one end connected to the intermediate storage bin 4 and the other end connected to the top of the raw material tank 1.

[0037] In the feeding unit, the solid material feeding bin 2 stores solid raw materials. An inclined feeding screw feeder 3 uses the rotation of its screw blades to push the raw materials upwards, conveying them to the intermediate storage bin 4 for temporary storage. A horizontally positioned metering screw feeder 5, through precise control of the number of rotations or the rotation speed, meteredly delivers the raw materials from the intermediate storage bin 4 to the top of the raw material tank 1, achieving a quantitative supply of solid raw materials. This ensures the continuity and accuracy of solid raw material delivery, stably providing a quantitative amount of large-particle ammonium sulfate raw material to the raw material tank 1 according to production needs, avoiding production fluctuations caused by unstable raw material supply, and providing a reliable raw material basis for subsequent dissolution and solution preparation.

[0038] Specifically, such as Figure 1 As shown, a tank level gauge 11 and a raw material tank thermometer 12 are installed in the raw material tank 1. The tank level gauge 11 is an ultrasonic level gauge or a radar level gauge, and the raw material tank thermometer 12 is a platinum resistance thermometer or a thermocouple thermometer.

[0039] The tank level gauge 11 installed in the raw material tank 1 is an ultrasonic level gauge or radar level gauge. It emits ultrasonic or electromagnetic waves, receives the echo after reflection from the liquid surface, and calculates the liquid level height based on the time difference between transmission and reception. The raw material tank thermometer 12 is a platinum resistance thermometer or thermocouple thermometer. It utilizes the principle that the resistance of a metal conductor or semiconductor changes with temperature, or that a closed circuit formed by two conductors of different materials generates a thermoelectric potential, to measure the temperature of the solution in the raw material tank 1 in real time. It can monitor the liquid level and temperature of the solution in the raw material tank 1 in real time and accurately, providing key data support for operators. Operators can replenish raw materials or control the feeding rate in a timely manner based on the liquid level data, and adjust the steam heating amount of the low-pressure steam pipe 10 based on the temperature data to ensure that the solution dissolves and is stored under suitable conditions, ensuring the stability of the production process and product quality.

[0040] Furthermore, such as Figure 1 As shown, an online hydrometer 13 is installed on the pipeline between the raw material tank 1 and the feed pump 14, and a feed flow meter 151 is installed on the outlet pipe 15.

[0041] An online hydrometer 13, installed on the pipeline between the raw material tank 1 and the feed pump 14, calculates the specific gravity of the solution in real time by detecting changes in physical quantities such as pressure and buoyancy of the solution on the sensor, based on Archimedes' principle or other physical measurement principles. A feed flow meter 151, installed on the outlet pipe 15, measures the flow rate of the solution through the pipeline using principles such as electromagnetic induction and turbine rotation. The online hydrometer 13 can monitor the specific gravity of the solution in the raw material tank 1 in real time, providing a basis for adjusting the solution concentration. When the specific gravity does not meet production requirements, it can be adjusted by adding solvent through the condensate pipe 8 or by adding solid raw materials using the feeding component. The feed flow meter 151 can accurately measure the flow rate of the output solution, facilitating control of production progress and product output, and also contributing to data statistics and analysis of the entire production process.

[0042] Furthermore, such as Figure 1 As shown, a drain pipe 16 is connected to one side of the bottom of the raw material tank 1. A drain valve is installed on the drain pipe 16, and the outlet end of the drain pipe 16 is connected to a waste liquid collection device.

[0043] The drain pipe 16, connected to one side of the bottom of the raw material tank 1, allows for easy and quick emptying of materials from the raw material tank 1. When cleaning, maintenance, or treatment of substandard solutions is required, the drain valve on the drain pipe 16 is opened, and under gravity, residual materials or waste liquid in the raw material tank 1 flow into the waste liquid collection device through the drain pipe 16. This facilitates the quick and easy emptying of materials from the raw material tank 1, preventing residual materials from corroding the equipment. It also facilitates centralized treatment of substandard products or cleaning waste liquid, reducing environmental pollution risks, ensuring normal equipment operation and a safe production environment, and promoting equipment maintenance and extending its service life.

[0044] Furthermore, such as Figure 1 , Figure 2 As shown, the raw material tank 1 is equipped with a raw material tank agitator 7 for breaking large ammonium sulfate raw materials into fine particles. The raw material tank agitator 7 has multiple dispersing blades distributed circumferentially along the rotation axis. The raw material tank agitator 7 is driven to rotate by a drive motor.

[0045] The drive motor rotates the agitator 7 inside the raw material tank 1, causing multiple dispersing blades distributed circumferentially along the axis to rotate accordingly. During rotation, these blades impact and shear the large particles of ammonium sulfate, breaking them down into smaller particles. Simultaneously, the agitator 7's stirring action ensures thorough mixing of the raw material and solvent, accelerating the dissolution process. This effectively improves the dissolution efficiency of large-particle ammonium sulfate, shortens the dissolution time, and ensures complete dissolution, avoiding incomplete or uneven dissolution caused by excessively large particles. This improves the quality and stability of the solution, providing a high-quality raw material solution for subsequent production, thereby enhancing product quality and production efficiency.

[0046] Furthermore, such as Figure 2 As shown, electric regulating valves and flow meters are installed on the condensate pipe 8, liquid brine raw material pipe 9, and low-pressure steam pipe 10, respectively. The electric regulating valves and flow meters are connected to the control system to accurately control the flow of each pipe.

[0047] Electric regulating valves installed on the condensate pipe 8, liquid brine raw material pipe 9, and low-pressure steam pipe 10 control the valve openings via electrical signals from the control system, thus regulating the flow rate of the fluid in the pipelines. Flow meters on each pipeline monitor the flow rate in real time and feed the flow data back to the control system. The control system automatically adjusts the opening of the electric regulating valves based on set parameters and actual measured flow data, achieving precise control of the flow rate in each pipeline. It can precisely control the flow rates of condensate from the condensate pipe 8, liquid raw material from the liquid brine raw material pipe 9, and low-pressure steam from the low-pressure steam pipe 10 according to the requirements of the production process, ensuring that parameters such as solution concentration and temperature meet production standards. By precisely controlling the addition amount of each material, dynamic adjustment of the solution composition and properties is achieved, improving the stability of the production process and the consistency of product quality, while also helping to reduce raw material consumption and improve production efficiency.

[0048] Furthermore, the raw material tank 1 has a double-layer jacket structure, with a steam flow chamber formed between the inner and outer layers. The low-pressure steam pipe 10 is connected to the steam flow chamber and is used to heat and keep the material in the raw material tank 1 warm. The condensate drainage system 6 includes a condensate drain pipe connected to the bottom of the steam flow chamber and a drain valve installed on the condensate drain pipe.

[0049] The double-jacketed structure of the raw material tank 1 forms a steam flow chamber. A low-pressure steam pipe 10 introduces steam into the steam flow chamber. During the steam flow within the chamber, heat is transferred to the inner layer of the raw material tank 1 through heat conduction, heating and maintaining the temperature of the material inside. The condensate drainage system 6 includes a condensate drain pipe connected to the bottom of the steam flow chamber and a drain valve installed on the condensate drain pipe. The drain valve automatically identifies steam and condensate. When the steam in the steam flow chamber condenses into water, the drain valve opens, draining the condensate and preventing steam leakage. The double-jacketed structure of the raw material tank 1 and the steam heating system effectively maintain a stable temperature of the material inside the raw material tank 1, reducing heat loss and energy consumption. The condensate drainage system 6 ensures the normal operation of the steam heating system, improves heating efficiency and stability, and guarantees that the solution dissolves and is stored under suitable temperature conditions, which is beneficial for improving product quality and production efficiency, while also extending the service life of the equipment.

[0050] When using the agricultural large-particle ammonium sulfate multifunctional raw material dissolution, storage and transportation device of this utility model, first conduct a comprehensive inspection to confirm that there are no foreign objects in the raw material tank 1, close the drain port valve on the drain pipe 16 to prevent material leakage; close the inlet valve of the liquid transfer pump 14 to prevent untreated solution from flowing out.

[0051] Open the main steam valve of the low-pressure steam pipe 10 to introduce steam into the steam flow chamber of the double-layer jacket structure of the raw material tank 1 to preheat the raw material tank 1; at the same time, open the main valve of the condensate or demineralized water of the condensate pipe 8 to start metering and controlling the water replenishment, so that the water level in the raw material tank 1 rises. During this process, the tank level gauge 11 monitors the liquid level change in real time, and the raw material tank thermometer 12 monitors the water temperature to ensure that the water replenishment and heating process is safe and stable.

[0052] After inspecting the solid material feeding silo 2 and the intermediate storage silo 4 and confirming that there are no foreign objects inside, power is supplied to the metering screw feeder 5 and the feeding screw feeder 3, and the equipment is started. The feeding screw feeder 3 conveys the solid non-conforming products in the solid material feeding silo 2 upward to the intermediate storage silo 4, and the metering screw feeder 5 then conveys the material in the intermediate storage silo 4 to the top of the raw material tank 1 according to the metering.

[0053] When the liquid level gauge 11 of the tank shows that the liquid level in the raw material tank 1 reaches 35%, the stirring paddle 7 of the raw material tank is started, and its dispersing blades begin to rotate to disperse the solid raw materials entering the raw material tank 1, while promoting the mixing of materials and water; the steam supply from the low-pressure steam pipe 10 is maintained to gradually increase the temperature in the raw material tank 1. When the temperature of the raw material tank thermometer 12 reaches 85-95℃ of the ammonium sulfate raw material solution, the solid raw materials begin to dissolve.

[0054] The online hydrometer 13 monitors the specific gravity of the raw material solution in real time. When the specific gravity reaches the production requirement of 1.23-1.27, the inlet valve of the feed pump 14 is opened, and the feed pump 14 is started to deliver the qualified raw material solution to the crystallization system through the outlet pipe 15. The specific gravity and salt concentration of the solution are continuously observed. When the raw material salt concentration reaches about 40% and the specific gravity is stable, the dissolving operation is stopped.

[0055] When the online hydrometer 13 detects that the specific gravity of the concentrated brine raw material 9 is lower than 1.25 or the lower limit of the specific gravity required for production, solid non-conforming products need to be added to increase the specific gravity of the solution. The solid material feeding silo 2 (including the dispersing equipment) and the intermediate storage silo 4 are checked again for foreign objects, and it is confirmed that the metering screw feeder 5 and the feeding screw feeder 3 are powered on and started. The solid non-conforming products are metered and then conveyed to the raw material tank 1 for dissolution via the metering screw feeder 5. The stirring paddle 7 in the running raw material tank continuously stirs to promote solid dissolution; at the same time, the steam heating system of the low-pressure steam pipe 10 is turned on to maintain a constant temperature of 85-95℃ in the raw material tank 1, accelerating the dissolution process. The online hydrometer 13 monitors the specific gravity change in real time. When the specific gravity reaches the production requirement of 1.23-1.27, the inlet valve of the liquid feed pump 14 is opened, and the liquid feed pump 14 is started to deliver the raw material solution for use by the crystallization system. This operation is maintained until the specific gravity of the raw material solution stabilizes, at which point the addition of solid raw materials is stopped.

[0056] If the online hydrometer 13 shows that the specific gravity of the concentrated brine raw material 9 is high, condensate needs to be added to reduce the specific gravity of the raw material solution. Open the condensate or demineralized water main valve of the condensate pipe 8 to perform metered and controlled water replenishment. The agitator 7 in the raw material tank continues to run to ensure that the replenished water and solution are fully mixed. Open the steam heating system of the low-pressure steam pipe 10 to maintain a constant temperature in the raw material tank 1 and avoid large temperature fluctuations caused by water replenishment that could affect the dissolution effect. The online hydrometer 13 monitors the specific gravity in real time. When the specific gravity drops to the value required for production, open the inlet valve of the feed pump 14 to start the feed pump 14 to deliver the raw material solution to the crystallization system and maintain this operation until the specific gravity of the raw material solution stabilizes, then stop water replenishment.

[0057] Throughout the operation, the tank level gauge 11 and the raw material tank thermometer 12 continuously monitor the liquid level and temperature in the raw material tank 1, providing real-time data for operators to adjust feeding, heating and other operations in a timely manner; the condensate drainage system 6 automatically discharges the condensate in the steam flow chamber to ensure stable steam heating effect; the liquid flow meter 151 on the outlet pipe 15 measures the output solution flow in real time, which is convenient for controlling production progress and output statistics.

[0058] When it is necessary to clean, repair, or treat substandard solutions in raw material tank 1, open the drain valve on drain pipe 16. Under the action of gravity, the residual materials or waste liquid in raw material tank 1 flow into the waste liquid collection device through drain pipe 16, thus completing the equipment maintenance and material cleaning work.

[0059] Finally, it should be noted that the electronic components in the online hydrometer 13, the liquid feed pump 14, etc. 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.

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.
