Description

Technical Field

[0001] This utility model relates to the field of phosphorus-iron alloy processing technology, and in particular to a device for precise adjustment of phosphorus-iron alloy composition. Background Technology

[0002] As an important auxiliary material in the iron and steel metallurgy industry, the precise control of phosphorus content, iron content and impurity composition of ferrophosphorus alloys directly affects the quality of steel products.

[0003] Currently, the processing and blending of ferrophosphorus alloys largely relies on manual calculation of raw material ratios based on experience, and the blending is completed by manually operating the feeding equipment. Manual calculation is easily affected by subjective factors, resulting in large ratio errors, which leads to fluctuations in alloy composition that exceed the allowable range. In addition, the control accuracy of raw material feeding is low, resulting in low production efficiency. Utility Model Content

[0004] To address the technical problem of low precision in the processing and preparation of ferrophosphorus alloys, this invention provides a device for precise preparation of ferrophosphorus alloy components.

[0005] This utility model is achieved using the following technical solution: A precise mixing device for phosphorus-iron alloy components includes: a first silo and a second silo for storing phosphorus and iron materials respectively; a tank disposed below the first silo and the second silo for mixing phosphorus-iron materials; a quantitative feeder disposed on the discharge pipes of the first silo and the second silo respectively; a guide shell disposed on the discharge end of the quantitative feeder, the discharge port of the guide shell being fixedly connected to the tank through a guide pipe; a solenoid valve disposed on the guide pipe; and a stirring mechanism disposed in the tank for stirring and mixing phosphorus-iron materials.

[0006] In this embodiment, the first silo and the second silo store phosphorus and iron materials respectively. When a mixing operation is required, the quantitative feeders on the discharge pipes of the first silo and the second silo are turned on. The quantitative feeders deliver the phosphorus and iron materials to the corresponding guide shells according to the preset raw material delivery amount. The guide shells guide the raw materials into the tank through the guide pipes. During the process, the timing of the raw materials entering the tank can be adjusted by controlling the solenoid valve on the guide pipe, so that the raw materials can enter the tank in sequence and as needed, laying the foundation for subsequent mixing operations. After both the phosphorus and iron materials have entered the tank, the stirring mechanism inside the tank is activated. During the operation of the stirring mechanism, the phosphorus and iron materials in the tank are mixed. Through continuous stirring, the phosphorus and iron materials are evenly distributed in the tank, reducing the composition difference caused by uneven mixing of raw materials. Compared with traditional manual stirring, this method does not require manual intervention in the stirring operation, reducing the intensity of manual labor. At the same time, the stable operation of the stirring mechanism can also ensure the consistency of the mixing process and improve the mixing effect of raw materials. Throughout the entire mixing process, the quantitative feeder can control the conveying amount of phosphorus and iron materials, avoiding errors caused by manual estimation of raw material usage. The solenoid valve can flexibly control the rhythm of raw material entering the tank, reducing waste during the conveying process. Finally, the mixed phosphorus and iron materials can be taken out of the tank. Through the coordinated action of various components, this system replaces the traditional method of manually calculating the proportion and manually operating the feeding, improving the automation level of the mixing process, helping to reduce the impact of human factors on the mixing results, and also shortening the time required for a single mixing, thus improving production efficiency.

[0007] As a further improvement to the above solution, the stirring mechanism includes: a shaft rotatably mounted on the tank via a sealed bearing; a stirring rod fixed on the shaft; a second motor fixed on the tank via a mounting bracket, the output shaft of the second motor being fixedly connected to the shaft via a coupling; and a scraper fixed on the stirring rod, the scraper being in contact with the inner wall of the tank.

[0008] In this embodiment, after the phosphorus and iron materials enter the tank, the second motor is started. The output shaft of the second motor drives the shaft to rotate through the coupling, and the shaft in turn drives the stirring rod fixed thereon to rotate synchronously. During the rotation of the stirring rod, the phosphorus and iron materials in the tank are stirred, which promotes full contact and mixing of the phosphorus and iron materials. While stirring the phosphorus and iron materials, the stirring rod drives the scraper to move along the inner wall of the tank. During the movement of the scraper, the phosphorus and iron materials attached to the inner wall of the tank can be scraped off, so that the scraped raw materials can re-enter the mixing system in the tank and participate in the subsequent stirring and mixing. This avoids the raw materials from adhering to the tank wall for a long time. Compared with a simple stirring structure, this method achieves stable transmission through motor drive, so that the rotation speed and stirring force of the stirring rod are consistent, reducing the local component differences caused by uneven stirring, and providing a guarantee for the quality of subsequent formulation. Throughout the mixing process, the sealed bearing reduces frictional resistance during shaft rotation and prevents raw materials from leaking from the connection between the shaft and the tank, thus reducing material loss. The second motor is connected to the shaft via a coupling, facilitating subsequent maintenance and replacement of the motor or shaft and reducing system maintenance costs. Furthermore, the motor-driven mixing method requires no manual intervention, further reducing labor intensity. Combined with the synergistic effect of the quantitative feeder and solenoid valve, the automation level of the entire mixing process is improved, contributing to increased production efficiency.

[0009] As a further improvement to the above solution, an auger is rotatably mounted inside the guide shell via bearings, and a first motor is fixed on the guide shell via an assembly frame. The output shaft of the first motor is fixedly connected to the auger via a coupling.

[0010] In this embodiment, after the quantitative feeder delivers the phosphorus or iron material to the guide shell, the first motor is started. The output shaft of the first motor drives the auger to rotate inside the guide shell through a coupling. During the rotation of the auger, the raw material inside the guide shell is pushed towards the discharge port, and the raw material enters the tank through the guide pipe. Compared with the method of conveying raw material by gravity alone, the pushing action of the auger can prevent the raw material from accumulating and blocking inside the guide shell, so that the raw material can be continuously and stably conveyed to the tank, ensuring the continuity of subsequent batching operations. Throughout the raw material conveying process, the bearing configuration reduces friction between the auger and the guide shell during auger rotation, reduces component wear, and extends the service life of the auger and guide shell. The first motor is fixed to the guide shell via an assembly frame, ensuring a stable connection structure, reducing vibration and noise during operation. Simultaneously, the auger's raw material conveying method can be coordinated with the feeding amount of the quantitative feeder to further optimize the raw material conveying rhythm, preventing the raw material from being conveyed too fast or too slow, which would affect the mixing efficiency. Combined with the action of the stirring mechanism, this improves the overall coordination of the system's operation.

[0011] As a further improvement to the above solution, a limiting seat is provided at the bottom of the tank, and a base plate is fixed at the bottom of the limiting seat. An electromagnetic heating plate that contacts the tank is provided on the base plate.

[0012] In this embodiment, after the phosphorus and iron materials enter the tank and the stirring mechanism is activated, the electromagnetic heating plate is turned on according to the mixing requirements. The electromagnetic heating plate transfers heat to the inside of the tank through contact with the bottom of the tank, heating the phosphorus and iron materials inside the tank. During the heating process, the limiting seat can restrict the position of the tank on the base plate to prevent the tank from shifting due to heating or stirring. The electromagnetic heating plate can continuously provide heat according to the set temperature parameters, so that the phosphorus and iron materials inside the tank can mix and react at a suitable temperature, providing temperature assurance for the mixing effect of the raw materials. Throughout the mixing process, the base plate provides a unified mounting carrier for the limiting seat and the electromagnetic heating plate, making the connection of each component more regular and facilitating subsequent maintenance of the tank and heating structure. The setting of the limiting seat enhances the stability of the tank placement and reduces tank displacement caused by equipment vibration. The electromagnetic heating plate heats the tank through contact heat transfer, which is more direct than traditional external heating methods and can reduce heat loss. At the same time, in conjunction with the stirring action of the stirring mechanism, the phosphorus iron material in the tank is heated more evenly, which helps to improve the quality of the mixed material and further optimize the mixing effect of the system.

[0013] As a further improvement to the above solution, a limiting rod is symmetrically fixed inside the limiting seat, and a sleeve block is sleeved on the limiting rod, and the sleeve block is fixedly connected to the tank body.

[0014] In this embodiment, when the system is running, the limiting rod restricts the lateral displacement of the sleeve block, thereby restricting the lateral displacement of the tank. This structure, together with the supporting role of the limiting seat itself, ensures that the tank always remains in the preset position during operation, avoiding the tank from shifting contact with the electromagnetic heating plate due to vibration or thermal deformation, and ensuring the stability of heat transfer. Throughout the entire process, the symmetrically arranged limiting rods and sleeves form a balanced limiting structure, which can reduce uneven local stress on the tank and extend the service life of the tank and the limiting seat. The connection method of the sleeves being fitted onto the limiting rods facilitates the subsequent disassembly and maintenance of the tank. When it is necessary to inspect the internal components of the tank, simply release the fixing of the sleeves to the tank, and the tank can be moved upwards. At the same time, this structure further improves the stability of the tank operation, indirectly ensuring the uniformity of raw material mixing and the consistency of heating, which helps to optimize the overall blending effect.

[0015] As a further improvement to the above solution, a liquid filling pipe and an exhaust pipe are fixedly connected to the tank body. The liquid filling pipe is used to connect to the liquid supply equipment for mixing ferrophosphorus alloy. Valves are provided on both the liquid filling pipe and the exhaust pipe.

[0016] In this embodiment, when mixing and blending ferrophosphorus materials in the tank, if liquid additives need to be added, the valve on the liquid addition pipe is opened, and the liquid supply equipment delivers the liquid additives into the tank through the liquid addition pipe. The opening time of the valve is controlled according to the blending requirements to adjust the amount of additives added. After the addition is completed, the valve on the liquid addition pipe is closed. If gas is generated in the tank during the stirring or heating process, the valve on the exhaust pipe is opened to allow the gas in the tank to be discharged through the exhaust pipe, so as to avoid the accumulation of gas affecting the mixing of raw materials or causing abnormal pressure in the tank. After the gas is discharged, the valve on the exhaust pipe is closed. Throughout the mixing process, the addition pipe allows liquid additives to be directly delivered into the tank without opening it, reducing the possibility of external impurities entering the tank. Combined with valve control, the timing and amount of additive addition can be flexibly adjusted. The vent pipe promptly discharges gases generated within the tank, maintaining a stable internal environment and ensuring the normal operation of the mixing mechanism. Furthermore, both pipes are equipped with valves that can remain closed when not in use, ensuring the tank's airtightness and further enhancing the controllability of the mixing process, thus helping to optimize the quality of the final product.

[0017] As a further improvement to the above solution, the limiting seat is equipped with a PLC controller and a temperature controller, and the bottom of the base plate is symmetrically fixed with support legs.

[0018] In this embodiment, when the system starts to mix ferrophosphorus alloy, the PLC controller presets parameters such as raw material ratio, stirring speed, and heating temperature. The PLC controller receives operating data from each component and automatically sends feeding instructions to the quantitative feeder, start / stop and speed adjustment instructions to the first and second motors, and temperature control instructions to the electromagnetic heating plate. At the same time, it controls the opening and closing of valves on the liquid addition pipe, exhaust pipe, and guide pipe. The support legs, through their own support, keep the base plate and the tank, limit seat, and other components above stable, preventing the system from shifting due to vibration during operation. Throughout the entire commissioning process, the PLC controller replaces the traditional manual operation of each component individually. Centralized control makes the operation of each component more coordinated, reduces human error, and facilitates real-time parameter adjustment according to commissioning requirements, thereby improving the system's controllability. The symmetrically arranged support legs increase the contact area between the base plate and the ground, lower the system's center of gravity, further enhance the stability of the overall structure, reduce the impact of vibration on the contact state between the electromagnetic heating plate and the tank, ensure heat transfer efficiency, and work together with other components of the system to improve the stability and efficiency of the commissioning process.
