[0002] In the lithium resource extraction industry, titanium lithium extraction adsorbent is widely used in lithium extraction processes of salt lake brine, lithium ore leaching solution and other systems due to its advantages of large adsorption capacity, high selectivity and strong stability. Titanium lithium extraction adsorbent usually needs to be processed into granular products of a specific particle size to meet the needs of industrial column adsorption, fluidized bed adsorption and other application scenarios.

[0003] The existing adsorbent granulation production line is generally of a universal type and mainly adopts traditional processes such as extrusion, breaking and screening, which has the following specific problems: Firstly, titanium lithium extraction adsorbent powder has a fine particle size and a large specific surface area, and is prone to agglomeration. The traditional production line lacks a dedicated pretreatment module, which leads to uneven mixing of materials during the granulation process, and the qualified rate of particles is only 60%-70%; Secondly, titanium powder and colloid have strong bonding sensitivity, and the temperature control precision of the traditional colloid preparation unit is low (±2℃ or more). Fluctuations in the temperature of the colloid can easily lead to insufficient particle strength and easy pulverization; Thirdly, the rotational speed of the traditional granulator is fixed or has a narrow adjustment range, which cannot adapt to the granulation needs of titanium powder, and the particle size uniformity of the particles is poor; Fourthly, a single parameter is used in the solidification process, and different particle sizes have inconsistent solidification effects, which affects the lithium extraction performance of the adsorbent; At the same time, the traditional production line has low automation and high manual involvement, and the production efficiency is low, with a material loss rate of 3-5%, which makes it difficult to improve the performance-price ratio of the product.

[0004] Therefore, in view of the special physical and chemical properties of titanium lithium extraction adsorbent powder, it is necessary to design a high-speed rotary granulation production line system that is highly targeted, highly automated and highly efficient, which is the key to solving the deficiencies of the prior art.

[0024] To overcome the shortcomings of existing general-purpose granulation production lines in terms of poor adaptability to titanium-based lithium extraction adsorbent powder, low particle qualification rate, low production efficiency, and high material loss, this invention provides an integrated high-speed rotary granulation production line system for titanium-based lithium extraction adsorbent powder, realizing efficient, precise, and large-scale production of titanium-based lithium extraction adsorbents.

[0025] See Figure 1 and combined Figures 2-4The titanium-based lithium-extraction adsorbent powder high-speed rotary granulation integrated production line system of this application includes a powder pretreatment-blending unit, a high-speed rotary precision granulation unit, a graded curing unit, and an intelligent control system 4 for coordinated control of the operation of each unit. The intelligent control system 4 is used to realize the linkage control of the entire process of titanium-based lithium-extraction adsorbent powder unpacking and pretreatment, blending, granulation, graded curing to finished product storage, and realize the fully automated production of titanium-based lithium-extraction adsorbent powder from pretreatment to finished product curing.

[0026] The powder pretreatment-blending unit consists of a blending platform 11, a powder unpacking and feeding system 12, a powder dispersion module 13, a metering system 14, a blending reactor 15, a finished glue storage tank 16, a precision temperature control module 17, a colloid conveying pipeline 18, and a blending machine control cabinet 19. The precision temperature control module 17 regulates the temperature of the blending reactor 15, the finished glue storage tank 16, and the colloid conveying pipeline 18, etc. Through the coordinated regulation of electric heating and circulating cooling, the temperature control accuracy is ±0.5℃, ensuring that the colloid is kept at a specific temperature of 35-55℃ before entering the granulation unit, which is suitable for the bonding characteristics of titanium-based powder and colloid.

[0027] The powder dispersion module 13 includes a high-frequency vibration disperser and an airflow homogenizer (not shown in the figure). The vibration frequency is 20-50Hz and the airflow pressure is 0.3-0.6MPa. It is used to break up the agglomerates of titanium-based lithium extraction adsorbent powder, and the particle size uniformity of the dispersed powder is ≥90%.

[0028] The combination of a high-frequency vibration disperser and an airflow homogenizer can break up agglomerates of titanium-based powders, ensuring that the powders are evenly dispersed before entering the compounding stage.

[0029] The high-speed rotating precision granulation unit consists of a granulation platform 21, a ton bag unpacking and feeding system 22, a conveying system 23, a secondary metering system 24, a high-speed rotating granulator 25, a grading and screening equipment 26, a large particle crushing and recycling module 27, a finished product conveying pipeline 28, and a control cabinet 29 next to the granulator.

[0030] The high-speed rotary granulator 25 has a stepless speed adjustment range of 500-1800 r / min and is equipped with an adjustable spray distribution device to ensure uniform contact between colloid and powder, and the particle size deviation of granulated particles is ≤0.3mm.

[0031] The grading and screening equipment 26 is equipped with at least four screening screens with apertures of 0.5mm, 1mm, 2mm and 3mm, respectively, for classifying particles into particle size ranges of 0.5-1mm, 1-2mm and 2-3mm.

[0032] Substandard fine powder is returned to the granulation unit for regranulation via a return pipeline. Specifically, the substandard fine powder is returned to the powder hopper of the granulation unit via a return pipeline, while large particles are processed by the crushing and recycling module, achieving a particle size compliance rate of ≥95%. By recycling substandard particles and re-participating them in granulation, the utilization rate of raw materials is improved.

[0033] The grading and curing unit consists of a curing gantry platform 31, a storage bin 32, a grading conveying module 33, a multi-tank curing water tank 34, a liftable basket 35, a gantry transfer system 36, an intelligent water circulation system 37, and a control cabinet 38 next to the curing machine. The multi-tank curing water tank 34 can adjust the curing time according to the particle size (0.5-1mm, 1-2mm, 2-3mm) after grading and screening. Specifically, 0.5-1mm particles are cured for 4-8 hours, 1-2mm particles for 8-12 hours, and 2-3mm particles for 12-16 hours, ensuring that particles of different sizes achieve stable mechanical strength and adsorption performance.

[0034] The intelligent water circulation system 37 is equipped with a water filtration device and a temperature stabilization module. The turbidity of the circulating water is ≤5 NTU, the temperature is controlled at 20-25℃, and the water resource recovery rate is ≥90%, which reduces production costs.

[0035] The intelligent control system 4 communicates and controls the sensors and actuators of each unit, and is used for real-time joint adjustment and control of material flow, colloid temperature, granulation speed and curing parameters. It also supports remote monitoring and data traceability, and the failure rate of automated operation is ≤0.5% / 1000h.

[0036] Specifically, the main control cabinet of the intelligent control system 4 works in conjunction with the local control cabinets of each unit, including the dispensing, granulation, and curing units, and is linked with temperature sensors, flow sensors, speed sensors, and level sensors to collect production data in real time. Each unit's local control cabinet can independently control its own equipment, while the main control cabinet can centrally control all the equipment in all units.

[0037] The intelligent control system 4 supports the joint adjustment and control of parameters such as granulation speed, colloid temperature, and curing time. It can remotely monitor the production status and generate data reports. The failure rate of automated operation is ≤0.5% / 1000h.

[0038] Material transfer between units is automated through sealed conveying equipment, with a powder loss rate of ≤0.3% during the conveying process.

[0039] The lining of the high-speed rotary granulator 25 is made of wear-resistant ceramic material with a service life of ≥8000h, and is equipped with an online cleaning device to prevent titanium powder from sticking to the inner wall of the equipment.

[0040] The integrated production line system in this application, with its powder pretreatment-adhesive mixing unit, is adapted to the characteristics of titanium-based powders, which are prone to agglomeration and sensitive to adhesion properties, by setting up a powder dispersion module 13 and a precision temperature control module 17.

[0041] The high-speed rotating granulation unit optimizes the rotation speed adjustment and spray fabric structure to improve particle uniformity.

[0042] The graded curing unit adjusts the curing parameters according to the particle size.

[0043] It solves the problems of poor adaptability of titanium-based lithium extraction adsorbent powder, low particle qualification rate, insufficient automation and low production efficiency in traditional granulation production lines. It features a compact structure, strong targeting, high production efficiency and excellent cost performance, and is suitable for large-scale production of titanium-based lithium extraction adsorbents.

[0044] Compared to existing general-purpose adsorbent granulation production lines, the high-speed rotary granulation integrated production line system for titanium-based lithium extraction adsorbent powder in this application has the following technical advantages: Highly targeted: Specifically designed for titanium-based lithium extraction adsorbent powders, it solves the problems of easy agglomeration and adhesion sensitivity of titanium-based powders through exclusive structures such as powder dispersion module 13 and precise temperature control module 17, increasing the particle qualification rate to over 95%.

[0045] High degree of automation: The entire process is integrated and controlled remotely, reducing human intervention by more than 80% and increasing production efficiency to 2-3 times that of traditional production lines.

[0046] High resource utilization rate: Through the recycling of substandard particles and the reuse of water resources, the material loss rate is ≤0.3% and the water resource recovery rate is ≥90%, thereby reducing production costs.

[0047] Excellent stability: The high-speed rotary granulator 25 adopts a wear-resistant ceramic lining and an online cleaning device, which extends the service life of the equipment, improves the stability of the production process, and reduces product performance fluctuations by ≤3%.

[0048] From a specific process perspective, in the powder pretreatment-blending unit, the titanium-based lithium extraction adsorbent powder enters the powder dispersion module 13 via the powder unpacking and feeding system 12 on the blending platform 11. After the vibration frequency is set to 35Hz and the airflow pressure to 0.4MPa, the agglomerates are broken up and then the powder is accurately metered (error ≤0.1%) by the metering system 14 and sent to the blending reactor 15.

[0049] In the mixing reactor 15, binder and deionized water are added in proportion, the stirring speed is 500 r / min, the reaction temperature is 45℃, and the colloid after the reaction is completed is stored in the finished colloid temporary storage vessel 16. The precise temperature control module 17 stabilizes the colloid temperature at 40℃ and sends it to the high-speed rotating precision granulation unit through the colloid delivery pipeline 18.

[0050] In the high-speed rotating precision granulation unit, the pretreated titanium-based powder is fed into the high-speed rotating granulator 25 through the conveying system 23 and the secondary metering system 24. The granulation speed is set to 1200 r / min. The colloid is evenly sprayed into the powder through the spraying and distributing device to form initial particles.

[0051] The initial particles enter the grading and screening equipment 26, and pass through four layers of screening screens of 0.5mm, 1mm, 2mm and 3mm to screen out qualified particles in three particle size ranges of 0.5-1mm, 1-2mm and 2-3mm. Fine powder smaller than 0.5mm is returned to the granulation unit through the return pipeline, and large particles larger than 3mm are processed by the crushing and recycling module 27 and then re-enter the granulator 25.

[0052] In the grading and curing unit, qualified particles after grading are sent to the storage bins 32 through the grading conveying module 33. Then, the gantry crane transfer system 36 puts the liftable baskets 35 containing particles of different sizes into the corresponding curing water tanks 34. The curing time is set to 6 hours for 0.5-1mm particles, 10 hours for 1-2mm particles, and 14 hours for 2-3mm particles. The water temperature of the curing water tank is maintained at 22℃.

[0053] The intelligent water circulation system 37 filters circulating water in real time, maintaining turbidity ≤5NTU and water resource recovery rate ≥90%. After solidification, the lifting basket 35 can be lifted to drain the granules, which are then sent to the finished product silo via the finished product conveying pipeline 28.

[0054] The intelligent control system 4 controls the temperature, pressure, flow rate, and speed of each unit in real time through the control cabinets 19 (next to the dispensing machine), 29 (next to the granulator), and 38 (next to the curing machine). The system uses a PLC controller to adjust the parameters. When the colloid temperature deviates from 40℃±0.5℃, the heating power of the precision temperature control module 17 is automatically adjusted. When the particle size distribution of the granulated particles deviates from the set value, the speed of the high-speed rotating granulator 25 and the spray material flow rate are automatically adjusted.

[0055] Each unit's local control cabinet can independently control the equipment in its unit, while the main control cabinet can control all the equipment in the unit.

[0056] It supports remote login to the monitoring platform to view production progress, equipment status and product qualification rate, and generate daily / weekly / monthly production reports to facilitate production management and quality traceability.
