Description

Technical Field

[0001] The invention relates to the technical field of lime digestion equipment, in particular to a steelmaking sintering batching modular lime digestion equipment. Background Art

[0002] The steelmaking sintering process is a vital part of steel production. The quality of sintered ore directly affects the production efficiency of the blast furnace and the final quality of steel. In the traditional steelmaking sintering process, lime is widely used to adjust the alkalinity of the ore and promote the melting of the ore. In order to improve the reaction efficiency of the sintered ore, lime slurry is usually mixed with other ore and added to the sintering belt by spraying. However, the existing lime slurry equipment has certain limitations, mainly reflected in the uniformity and accuracy of the ingredients. The traditional batching system cannot accurately control the amount and distribution of ingredients, which often leads to uneven distribution of lime in the lime slurry, affecting the chemical composition and alkalinity adjustment of the sintered ore, and then affecting the quality of the sintered ore and the stability of the sintering process.

[0003] In the prior art, most lime slaking equipment relies on manual or semi-automatic methods for batching, and the human factors during the operation make it difficult to ensure the accuracy of the batching. The batching method in traditional equipment is often rough, and the material injection method is not accurate enough, resulting in uneven distribution of lime in the ore. Especially in high temperature and humid environments, lime particles are prone to sedimentation and agglomeration, forming a "dead zone", which causes excessive or insufficient lime content in the ore, thereby affecting the reaction efficiency of the ore and the temperature control stability during the sintering process. In addition, existing equipment is difficult to adjust in real time according to different production process requirements, lacks automation and intelligent control, resulting in high energy consumption, low production efficiency, and limited control over the environment.

[0004] Based on the above shortcomings of the existing technology, there is an urgent need for a device that can accurately and efficiently inject the ingredients into the lime slurry evenly to ensure the accurate placement of the ingredients and optimize the ore reaction during the sintering process. Summary of the invention

[0005] The purpose of the embodiment of the present invention is to provide a modular lime slaking equipment for steelmaking sintering batching, aiming to solve the technical problems mentioned in the background technology.

[0006] To achieve the above object, the present invention provides the following technical solutions: A modular lime digestion equipment for steelmaking sintering batching, comprising a mixing barrel main body, and a mixing barrel top cover is arranged at one end of the mixing barrel main body, a first lifting block is slidably connected to the surface of the mixing barrel main body, and an electromagnet block is installed inside the first lifting block, and a driving component is jointly arranged on the surface of the mixing barrel main body and the first lifting block, and the driving component is used to drive the first lifting block to move; The mixing barrel body is slidably connected with a second lifting block inside, and a side of the second lifting block is connected with a batching storage barrel, an air pump installation box is arranged inside the batching storage barrel, and an air pump is installed inside the air pump installation box, and an air suction pipe and an air injection pipe are respectively connected to the two sides of the outer side of the air pump, a feeding pipe is connected to the surface of the batching storage barrel, and a sealing cover is sleeved on one end of the feeding pipe, a delivery pipe is connected inside the batching storage barrel, and a first solenoid valve is installed on the outer side of the delivery pipe; One end of the gas injection pipe away from the ingredient storage barrel is connected to a hollow barrel, the interior of the hollow barrel is connected to a material spraying pipe, and a second solenoid valve is installed on the outer side of the material spraying pipe.

[0007] Furthermore, a first slide groove is provided on the surface of the mixing barrel body, a first slider is installed on the side of the first lifting block, and the first lifting block is slidably connected to the surface of the mixing barrel body through the cooperation of the first slider and the first slide groove; A second slide groove is provided inside the mixing barrel body, a second slider is installed on the side of the second lifting block, and the second lifting block is slidably connected inside the mixing barrel body through the cooperation of the second slider and the second slide groove; The positions of the second lifting block and the first lifting block correspond to each other.

[0008] Furthermore, the driving assembly includes a mounting frame, and the mounting frame is connected to the surface of the mixing barrel body, and a driving motor is installed inside the mounting frame; A bearing seat is installed on the surface of the mixing barrel body, and a transmission screw is installed inside the bearing seat and at the output end of the driving motor. A transmission threaded hole is opened on the surface of the first lifting block, and the transmission screw is meshed and connected inside the transmission threaded hole.

[0009] Furthermore, a first through hole and a second through hole are formed on the surface of the mixing barrel top cover, and the first through hole and the air intake pipe are on the same axis, and the second through hole and the sealing cover are on the same axis; The inner diameters of the first through hole and the second through hole are respectively the same as the outer diameters of the air intake pipe and the sealing cover.

[0010] Furthermore, one end of the gas injection pipe and the conveying pipe away from the ingredient storage barrel is connected to the interior of the hollow barrel.

[0011] Furthermore, a stirring motor is installed on the surface of the top cover of the mixing barrel, and a rotating rod is installed on the output end of the stirring motor, and a plurality of stirring blades are arranged on the outer side of the rotating rod.

[0012] Furthermore, a PLC intelligent controller is installed on the surface of the mixing barrel body.

[0013] The invention provides a modular lime digestion equipment for steelmaking sintering batching, which has the following beneficial effects: By accurately and efficiently injecting the ingredients into the lime slurry, the uniformity of the sintering ingredients can be significantly improved, which has an important positive impact on the sintering process and steelmaking effect. First of all, the uniform distribution of ingredients ensures the complete reaction of lime in the sinter, so that the chemical composition and alkalinity of the ore can be accurately controlled. Lime is a key component for adjusting alkalinity and promoting ore melting during sintering. If the lime slurry is unevenly distributed, it may cause local alkalinity to be too high or too low, affecting the quality and reaction efficiency of the sinter. Through high-pressure injection and airflow-assisted conveying technology, the ingredients can be quickly and evenly distributed in the slurry, avoiding material sedimentation and agglomeration, and ensuring the uniformity and sufficiency of the ore reaction.

[0014] In addition, precise batch injection not only improves the mixing efficiency of batch and lime slurry, but also optimizes the temperature control during sintering. Since the melting points of lime and ore are close, uneven batch distribution may cause local overheating or temperature instability, thus affecting the temperature control of the sintering zone and the quality of the sintered ore. By uniformly injecting batch, the temperature gradient during sintering can be stabilized, overheating or overcooling can be reduced, and the sintering process can be smoothly carried out.

[0015] The implementation of this precise batching technology not only helps to improve the recovery rate of sintered ore and improve the physical and chemical properties of sintered ore, but also effectively reduces energy consumption. By improving the reaction efficiency of the sintering process and optimizing material utilization, the steelmaking efficiency can be further improved, the production cost can be reduced, and the impact on the environment can be effectively controlled. Overall, the precise batching system provides higher stability and better production performance for the sintering process, and is one of the key technologies to improve the quality and efficiency of modern steelmaking processes.

DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0023] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0024] like Figure 1-Figure 5 As shown, a steelmaking sintering batching modular lime digestion equipment provided by an embodiment of the present invention includes a mixing barrel body 1, and a support leg 8 is connected to the surface of the mixing barrel body 1. A mixing barrel top cover 2 is provided at one end of the mixing barrel body 1, and a feed port 4 is provided on the surface of the mixing barrel top cover 2. A stirring motor 5 is installed on the surface of the mixing barrel top cover 2, and a rotating rod 9 is installed at the output end of the stirring motor 5, and a plurality of stirring blades 10 are provided on the outer side of the rotating rod 9.

[0025] The surface of the mixing barrel main body 1 is slidably connected with a first lifting block 7, a first slide groove is opened on the surface of the mixing barrel main body 1, a first slider is installed on the side of the first lifting block 7, and the first lifting block 7 is slidably connected to the surface of the mixing barrel main body 1 through the cooperation of the first slider and the first slide groove.

[0026] An electromagnet block is installed inside the first lifting block 7 , and a driving component 3 is provided on the surface of the mixing barrel body 1 and the first lifting block 7 , and the driving component 3 is used to drive the first lifting block 7 to move.

[0027] A second lifting block 14 is slidably connected inside the mixing barrel body 1, a second slide groove is opened inside the mixing barrel body 1, a second slider is installed on the side of the second lifting block 14, and the second lifting block 14 is slidably connected inside the mixing barrel body 1 through the cooperation of the second slider and the second slide groove.

[0028] The positions of the second lifting block 14 and the first lifting block 7 correspond to each other, that is, the two are at the same height.

[0029] The side of the second lifting block 14 is connected to the ingredient storage barrel 13, the inside of the ingredient storage barrel 13 is provided with an air pump installation box 22, and the inside of the air pump installation box 22 is installed with an air pump, the two sides of the outside of the air pump are respectively connected to the suction pipe 6 and the air injection pipe 17, the surface of the ingredient storage barrel 13 is connected to the feeding pipe 16, and one end of the feeding pipe 16 is sleeved with a sealing cover 15, the inside of the ingredient storage barrel 13 is connected to the delivery pipe 20, and the outside of the delivery pipe 20 is installed with a first solenoid valve 19. The ends of the air injection pipe 17 and the delivery pipe 20 away from the ingredient storage barrel 13 are connected to the inside of the hollow barrel 21.

[0030] One end of the gas injection pipe 17 away from the ingredient storage barrel 13 is connected to a hollow barrel 21 , the interior of the hollow barrel 21 is connected to a material spraying pipe 18 , and a second solenoid valve 23 is installed on the outer side of the material spraying pipe 18 .

[0031] In one embodiment of the present invention, after a predetermined amount of lime slurry has been contained in the mixing barrel body 1, the batching storage barrel 13 and the second lifting block 14 are in the initial position, that is, set at the highest point in the mixing barrel body 1. At this time, the batching storage barrel 13 is located above the mixing barrel body 1, ensuring that there is no contact between the batching storage barrel 13 and its components and the stirring blade 10. In this state, the sealing cover 15 is located above the surface of the mixing barrel top cover 2, and the feeding pipe 16 passes through the second through hole 12. The staff can first unscrew the sealing cover 15 and add the prepared ingredients to the batching storage barrel 13 through the feeding pipe 16 until the predetermined amount of ingredients is loaded into the batching storage barrel 13. Subsequently, the sealing cover 15 is re-fixed on the feeding pipe 16 to ensure sealing.

[0032] At this stage, the staff checks the position of the stirring blade 10 to ensure that it does not interfere with the ingredient storage barrel 13, and then starts the stirring motor 5. The stirring motor 5 drives the rotating rod 9 to rotate the stirring blade 10 to a suitable angle to ensure that the stirring blade 10 does not physically contact the ingredient storage barrel 13. When the stirring blade 10 rotates to no longer be in the same plane as the ingredient storage barrel 13, the ingredient storage barrel 13 can start to move downward without being interfered by the stirring blade 10.

[0033] Next, the staff starts the drive assembly 3 and activates the electromagnet block. After the electromagnet block is energized, it generates an adsorption force to adsorb the second lifting block 14. Since the second lifting block 14 is made of iron material, the electromagnetic adsorption force is sufficient to adsorb it. The drive assembly 3 starts to drive the first lifting block 7 and the attached second lifting block 14 to move downward. Whenever the second lifting block 14 moves to the set position, the staff opens the first solenoid valve 19, and the ingredients inside the ingredient storage barrel 13 are smoothly injected into the hollow barrel 21 through the delivery pipe 20.

[0034] Then, the staff starts the air pump, which sucks in external air through the air suction pipe 6 and injects it into the air injection pipe 17 and the hollow barrel 21 until the air pressure inside the hollow barrel 21 reaches the set value. After the air pump is turned off, the staff opens the second solenoid valve 23, and the ingredients in the hollow barrel 21 are quickly sprayed through the injection pipe 18 under the action of high-pressure air and injected into the lime slurry. At this time, due to the injection pressure, the ingredients can be evenly distributed in the lime slurry, ensuring a more uniform mixing effect.

[0035] As the batching storage barrel 13 moves downward, the operation continues, and the batching can be evenly sprayed in the lime slurry at different heights and levels. The length design of the suction pipe 6 ensures that even if the batching storage barrel 13 moves to the lowest position, the suction pipe port is still higher than the surface of the mixing barrel top cover 2, ensuring the stable operation of the system.

[0036] In summary, by accurately and efficiently injecting the ingredients into the lime slurry, the uniformity of the sintering ingredients can be significantly improved, which has an important positive impact on the sintering process and steelmaking effect. First, the uniform distribution of ingredients ensures the complete reaction of lime in the sintered ore, so that the chemical composition and alkalinity of the ore can be accurately controlled. Lime is a key component for adjusting alkalinity and promoting ore melting during sintering. If the lime slurry is unevenly distributed, it may cause local alkalinity to be too high or too low, affecting the quality and reaction efficiency of the sintered ore. Through high-pressure injection and airflow-assisted conveying technology, the ingredients can be quickly and evenly distributed in the slurry, avoiding material sedimentation and agglomeration, and ensuring the uniformity and sufficiency of the ore reaction.

[0037] In addition, precise batch injection not only improves the mixing efficiency of batch and lime slurry, but also optimizes the temperature control during sintering. Since the melting points of lime and ore are close, uneven batch distribution may cause local overheating or temperature instability, thus affecting the temperature control of the sintering zone and the quality of the sintered ore. By uniformly injecting batch, the temperature gradient during sintering can be stabilized, overheating or overcooling can be reduced, and the sintering process can be smoothly carried out.

[0038] The implementation of this precise batching technology not only helps to improve the recovery rate of sintered ore and improve the physical and chemical properties of sintered ore, but also effectively reduces energy consumption. By improving the reaction efficiency of the sintering process and optimizing material utilization, the steelmaking efficiency can be further improved, the production cost can be reduced, and the impact on the environment can be effectively controlled. Overall, the precise batching system provides higher stability and better production performance for the sintering process, and is one of the key technologies to improve the quality and efficiency of modern steelmaking processes.

[0039] In the actual implementation of the above technical solution, the following points need to be noted: 1. Stability of the mixing barrel body 1: The support legs 8 of the mixing barrel body 1 need to ensure that the equipment does not vibrate or move during the mixing process. Therefore, the design of the support legs 8 should take into account the uniform distribution of load and can be adjusted according to actual needs to cope with different types of materials.

[0040] 2. Matching of stirring motor 5 and rotating rod 9: The power of the stirring motor 5 should be selected according to the viscosity of the lime slurry in the mixing barrel body 1, the type and amount of the ingredients, to ensure that it has sufficient torque to overcome the adhesion and resistance of the material and achieve effective stirring.

[0041] 3. Cooperation between lifting block 7 and electromagnet block: The connection between the first lifting block 7 and the electromagnet block should be designed as an anti-falling structure to ensure that the electromagnet block can continue to generate strong suction during operation and avoid failure under high load.

[0042] 4. Feeding system of ingredient storage barrel 13: The feeding system of the ingredient storage barrel 13 needs to have an anti-blocking design, especially when the ingredient particles are large, the system should ensure smooth injection of the ingredients through vibration or airflow assistance. The sealing of the feeding pipe 16 should be strictly controlled to prevent material leakage during operation.

[0043] 5. Pressure control of air pump and spray pipe: To ensure uniformity and efficiency of the material injection, the flow rate of the air pump and the design of the injection pipe should ensure constant air pressure to avoid uneven injection of the material due to air pressure fluctuations. The discharge port of the injection pipe 18 needs to be designed to be adjustable to meet the injection requirements of different material quantities and different materials.

[0044] 6. Security and monitoring system: In order to prevent equipment failure during operation, a real-time monitoring system should be added to the solution, especially in key components such as electromagnet blocks, air pumps, valves and stirring motors. The monitoring system can provide real-time feedback on the equipment status and ensure the coordinated operation of each link.

[0045] 7. Automation and human-machine interface design: The automation level of the equipment should be further improved, and the lifting block, stirring motor, air pump, valve and other components should be automatically controlled through PLC or embedded control system. The human-machine interface (HMI) should have an intuitive operation interface and real-time data feedback function, so that the operator can monitor the system operation status at any time and make adjustments as needed.

[0046] 8. Design of material conveying pipeline: The conveying pipeline (such as the conveying pipe 20, the air injection pipe 17, etc.) should have anti-corrosion and anti-clogging functions. Especially in the process of conveying ingredients and airflow, the pipeline design should ensure smooth passage of materials and reduce material accumulation.

[0047] In this embodiment, the driving assembly 3 includes a mounting frame 32, and the mounting frame 32 is connected to the surface of the mixing barrel body 1, and a driving motor 31 is installed inside the mounting frame 32; A bearing seat 34 is installed on the surface of the mixing barrel body 1, and a transmission screw 33 is installed inside the bearing seat 34 and at the output end of the driving motor 31. A transmission threaded hole is opened on the surface of the first lifting block 7, and the transmission screw 33 is meshed and connected inside the transmission threaded hole.

[0048] In this embodiment, the mounting frame 32 fixes the driving motor 31 on the surface of the mixing barrel body 1. The driving motor 31 is driven by electricity to drive the transmission screw 33 to rotate. One end of the transmission screw 33 is connected to the output end of the driving motor 31, and the other end is installed in the bearing seat 34 of the mixing barrel body 1. The bearing seat 34 is used to support and stabilize the rotation of the screw, reduce the wear caused by friction or vibration, and improve the stability and durability of the system. The threaded portion of the transmission screw 33 is engaged with the transmission threaded hole of the first lifting block 7. After the driving motor 31 is started, the screw rotates to make the lifting block 7 move up and down along its guide rail.

[0049] This design enables the drive motor 31 to accurately control the vertical movement of the lifting block 7 by rotating the lead screw, ensuring that the ingredient storage barrel 13 can be accurately adjusted up and down as needed, thereby achieving accurate control of the ingredient delivery. The speed and power of the drive motor can be adjusted as needed to ensure that the system can operate stably under different loads. Through the cooperation of this transmission system, the accuracy and stability of the movement of the ingredient storage barrel 13 during the entire operation process can be guaranteed, thereby improving the working efficiency and reliability of the ingredient system.

[0050] In this embodiment, a first through hole 11 and a second through hole 12 are formed on the surface of the mixing barrel top cover 2, and the first through hole 11 and the air intake pipe 6 are on the same axis, and the second through hole 12 and the sealing cover 15 are on the same axis; The inner diameters of the first through hole 11 and the second through hole 12 are respectively the same as the outer diameters of the air intake pipe 6 and the sealing cover 15 .

[0051] The main basis for this setting is to ensure the sealing of the system and the smoothness of fluid transmission during operation. First of all, the first through hole 11 is on the same axis as the air intake pipe 6. This design ensures that the installation of the air intake pipe 6 and the docking between the through hole 11 are accurate and correct, and ensures that the outside air can smoothly enter the mixing barrel body 1 through the air intake pipe 6 to form the necessary airflow power, especially during the gas injection and ingredient injection process. The outer diameter of the air intake pipe 6 is the same as the inner diameter of the first through hole 11, which can avoid air leakage or poor airflow due to mismatched accessories, thereby ensuring the stability of the airflow and the efficient operation of the system.

[0052] Similarly, the design of the second through hole 12 and the sealing cover 15 on the same axis ensures that the sealing cover 15 can be accurately connected and sealed with the feeding pipe 16. The sealing cover 15 has the same inner and outer diameters as the second through hole 12, which can effectively prevent material leakage or infiltration of external air caused by poor sealing, ensuring that the process of adding ingredients is smooth and will not affect the environmental conditions in the mixing barrel. The close connection of the sealing cover 15 prevents the overflow or contamination of materials during the feeding process, helps to maintain the stability of the internal pressure of the system and avoid unnecessary material loss.

[0053] This design ensures the coordinated work of airflow, materials and equipment components in the system through precise docking and good sealing, reduces unnecessary energy waste, and improves batching accuracy and the overall efficiency of the system.

[0054] In this embodiment, a PLC intelligent controller is installed on the surface of the mixing barrel body 1. In this embodiment, a PLC intelligent controller is installed on the surface of the mixing barrel body 1, and its main purpose is to improve the automation, accuracy and ease of operation of the entire batching system. PLC (Programmable Logic Controller) as the core control unit can realize precise control of each component in the mixing barrel body 1, especially in the coordinated operation of equipment such as batching, stirring, solenoid valves and air pumps.

[0055] First, the PLC controller can monitor the working status inside the mixing barrel body 1 in real time by connecting with various devices. By inputting the set process parameters, the PLC controller can automatically adjust and control the working status of components such as the drive motor, transmission screw, and solenoid valve. For example, the PLC can accurately control the up and down movement of the lifting block according to the preset program to ensure the movement accuracy of the batching storage barrel 13 and avoid uneven batching caused by human errors or improper operation.

[0056] Secondly, the PLC controller has real-time data collection and feedback functions. It can monitor the working status of the mixing motor, solenoid valve and air pump, and provide real-time feedback on the air flow pressure, batching amount and mixing status in the mixing barrel through the set sensors. When the system operation is abnormal, the PLC can issue an alarm in time and adjust related operations to ensure the stability and safety of the system. This automated control system greatly reduces manual intervention and improves production efficiency and the accuracy of the batching process.

[0057] In addition, the application of PLC controller also enables the system to flexibly adjust working parameters according to actual needs. Operators can perform simple programming and adjustments to PLC through the human-machine interface (HMI) to ensure that the system can work adaptively under different production conditions, improving the flexibility and operability of the entire equipment. Through the PLC control system, the entire batching process can be operated more efficiently and stably, reducing the impact of human factors on equipment performance and improving the degree of automation of production.

[0058] In this embodiment, the batching storage barrel 13 and the various components mounted on the batching storage barrel 13 are all made of anti-corrosion materials, or their surfaces are coated with anti-corrosion coatings. The main basis for this design is to deal with the corrosion problems that may occur in long-term contact with chemical substances and in high humidity environments. During the steelmaking sintering batching process, some corrosive materials such as lime, mineral powder, etc. may need to be stored or processed in the batching storage barrel 13, and these materials themselves or the chemical substances generated during the reaction process may cause corrosion to the equipment materials. Therefore, the use of anti-corrosion materials or coatings can effectively extend the service life of the equipment and ensure the long-term stable operation of the equipment in harsh environments.

[0059] First, anti-corrosion materials can effectively prevent the equipment from being damaged due to reaction with corrosive substances during long-term use, and avoid equipment failure or production accidents caused by corrosion. In particular, the interior of the ingredient storage barrel 13 is in contact with powdered ingredients and liquid substances for a long time. If the material does not have anti-corrosion properties, it is easy to rust, corrode or surface damage, which will affect the precise delivery and mixing effect of the ingredients. Using anti-corrosion materials, such as stainless steel, polymer coatings, etc., can greatly improve the durability and stability of the equipment.

[0060] Secondly, the application of anti-corrosion coatings can not only directly improve the corrosion resistance of the material surface, but also reduce the workload of cleaning and maintenance. During operation, the contact between the material and the equipment surface is inevitable, and the anti-corrosion coating can effectively isolate the direct contact between the corrosive substances and the metal surface of the equipment, prevent corrosive gases or liquids from entering the interior of the equipment, and ensure the normal function and long-term use of each component of the equipment.

[0061] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
