Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments. In the following detailed description, only certain exemplary embodiments of the present invention are described by way of illustration. Undoubtedly, those skilled in the art will recognize that various modifications can be made to the described embodiments without departing from the spirit and scope of the present invention. Therefore, the drawings and description are illustrative in nature and not intended to limit the scope of the claims.

[0017] like Figures 1 to 15 As shown, the multi-raw material co-processing and high-precision proportioning production system includes a raw material crushing zone, a raw material lifting and storage zone, a raw material metering and proportioning zone, a pre-calcination buffer zone, a pre-calcination self-unloading hopper zone, a post-calcination cooling zone, and a post-calcination storage and shipping zone, arranged sequentially along the raw material travel direction. The downstream zone can receive raw materials output from its adjacent upstream zone. A temporary manual mixing zone is also provided in conjunction with the raw material metering and proportioning zone. By rationally arranging these zones, they are essentially connected in series along the raw material travel direction, and the system features a high-low arrangement during raw material transport, making full use of the available space. This allows for continuous and high-precision proportioning and mixing. Furthermore, the temporary manual mixing zone enables a combination of automatic and manual feeding to meet the needs of adding ingredients during production, making the system's continuous production more flexible and reliable.

[0018] like Figure 2 and Figure 3As shown, the raw material crushing zone includes hydraulic tippers 2 arranged in parallel for unloading dump trucks 1. Each hydraulic tipper 2 has a corresponding unloading pit hopper 3 fixedly installed on one side to receive the raw materials in the dump truck 1. The discharge port of the unloading pit hopper 3 unloads the raw materials into a double roll crusher 5 through a vibrating feeder 4. The discharge end of the double roll crusher 5 transports the crushed raw materials to the raw material lifting and storage area through a crushing zone belt conveyor 6. Magnetic suspended metal adsorbers are arranged along the crushing zone belt conveyor 6 to remove magnetic metals such as iron from the raw materials.

[0019] In this embodiment, the hydraulic tipper 2 is located in the pit, and three units are arranged side by side. Correspondingly, three sets of unloading pit hoppers 3, vibrating feeders 4, double-roll crushers 5, and belt conveyors 6 in the crushing zone are also provided. After the dump truck 1 is in place, the hydraulic tipper 2 lifts the dump truck 1, tilting it so that the front is higher than the back, allowing the loaded material to be automatically unloaded into the unloading pit hopper 3. Using the hydraulic tipper 2 to lift and unload the dump truck 1 as a whole increases the automation of unloading and reduces the configuration of loaders, unloading time, and labor waste. The material in the unloading pit hopper 3 is continuously and evenly conveyed to the double-roll crusher 5 for crushing under the action of the vibrating feeder 4. This crushing and feeding method can effectively prevent the crusher from being overloaded or running idle.

[0020] The three hydraulic tipping machines 2 and related supporting facilities are configured in parallel, enabling the crushing of a single type of raw material or a mixture of three raw materials. They can also be configured for operation with one backup line and two backup lines, or one backup line and one backup line. The crushed raw materials can be transported in a fully sealed manner to the raw material lifting and storage area via the belt conveyor 6 in the crushing zone.

[0021] like Figure 4 and Figure 5 As shown, the raw material lifting and storage area includes raw material elevators 7 corresponding to each of the belt conveyors. Two rows of storage silos 8 are installed on the discharge side of each raw material elevator 7. A mobile material cart mechanism is installed above each row of storage silos 8. A reversible belt conveyor 10 connects the two mobile material cart mechanisms, and the reversible belt conveyor 10 is positioned between the two mobile material cart mechanisms on the side closest to the raw material elevators 7. Each storage silo 8 has a discharge port arranged in an inward and outward direction at its bottom. The mobile material cart mechanism includes a track 9 and a mobile belt unloading cart 11 used in conjunction to distribute raw materials into each storage silo 8.

[0022] The raw material elevator 7 is set up one-to-one with the belt conveyor 6 in the crushing zone. The raw material elevator 7 is used to realize the vertical and fully enclosed transportation of raw materials. With the cooperation of the reversible belt conveyor 10 in the storage zone, the raw materials are loaded onto the mobile belt unloading car 11. By controlling the mobile belt unloading car 11, the material is fed to each of the storage silos 8 at a fixed point.

[0023] In this embodiment, the storage silos 8 are arranged in two rows, with four silos 8 in each row, resulting in a total of eight storage silos 8. Therefore, there are two rail tracks 9 and two mobile belt unloading vehicles 11. The mobile belt unloading vehicles 11, through a PLC controller combined with coding technology and the high and low material level interlocking of the storage silos 8, automatically determine the capacity of the raw materials in the silos, achieving fixed-point unloading and storage of the eight silos. This ensures a continuous supply of raw materials, eliminates the production impact caused by insufficient raw material supply, provides a stable material source for subsequent metering and batching, and acts as a supply buffer. The use of a PLC controller for the above functions is well-known to those skilled in the art and will not be described in detail here.

[0024] like Figure 6 and Figure 7 As shown, the raw material metering and proportioning area includes discharge belt conveyors 12 respectively arranged along the two rows of storage silos 8, and the discharge belt conveyors 12 are located below the storage silos 8. The discharge ports on the outer sides of the two rows of storage silos 8 respectively discharge material to the corresponding discharge belt conveyor 12 through a quantitative feeder 13. A reversible belt conveyor 14 of the proportioning area is connected between the two opposite discharge ports on the inner sides of the two rows of storage silos 8, and each discharge port is respectively connected to... The material is discharged from the quantitative feeder 13 to the corresponding reversible belt conveyor 14 of the proportioning zone. Each of the reversible belt conveyors 14 of the proportioning zone and the discharge belt conveyor 12 are arranged in a spatially intersecting manner, and both ends of each of the reversible belt conveyors 14 of the proportioning zone can discharge material to the discharge belt conveyor 12. The material also includes a proportioning zone elevator 15 installed at the discharge end of the discharge belt conveyor 12, and the proportioning zone elevator 15 discharges material to the pre-calcination buffer zone.

[0025] Specifically, each of the storage silos 8 has four rectangular discharge ports at its bottom, with the discharge ports of the two rows of storage silos 8 corresponding to each other. Therefore, the eight storage silos 8 form a total of thirty-two discharge ports. Each port can be precisely fed by the quantitative feeder 13, and with the help of PLC control, real-time feedback of the proportioning weight signal can be achieved, enabling continuous (or quasi-continuous) online weighing, mixing, and flow control, thereby improving the accuracy of the proportioning. Utilizing the continuous conveying characteristics of the reversible belt conveyor 14 in the proportioning zone, raw materials can be taken from different storage silos 8 and batch-metered and proportioned, and finally transported to the proportioning zone elevator 15 by the two discharge belt conveyors 12. Figure 7 As can be seen, in this embodiment, one of the discharge belt conveyors 12 is equipped with two proportioning zone elevators 15. Therefore, each of the discharge belt conveyors 12 discharges material to the corresponding proportioning zone elevator 15 through the equipped single-sided plow-type unloader 16.

[0026] like Figure 6 and Figure 7 As shown, the ends of each of the discharge belt conveyors 12 extend to the outside of the corresponding proportioning zone elevator 15. The temporary manual mixing zone includes a manual mixing belt conveyor 17 installed at the end of each discharge belt conveyor 12. The bottom of the discharge end of the manual mixing belt conveyor 17 is provided with a manual mixing bin 18 for receiving residual material. It also includes a temporary feeding hopper 19 correspondingly installed on the side of each discharge belt conveyor 12. The temporary feeding hopper 19 feeds material to the temporary double roll crusher 21 through a temporary feeding belt 20. The temporary double roll crusher 21 feeds material to the corresponding discharge belt conveyor 12 through a temporary discharge belt 22.

[0027] When additional ingredients need to be added during the production process, the raw materials output from the storage silo 8 can be first fed into the manual mixing bin 18 via the manual mixing belt conveyor 17. Then, with the help of a loader, the raw materials to be added are placed into the temporary feeding hopper 19, and then fed into the temporary double-roll crusher 21 via the temporary feeding belt 20 for crushing and mixing. Finally, the raw materials are fed into the discharge belt conveyor 12 via the temporary discharge belt 22, and transferred to the proportioning zone elevator 15 by the single-sided plow-type unloader 16, increasing the flexibility of production.

[0028] The raw material metering and proportioning area is a key process in the batching process. It is configured with 32 quantitative feeders 13, 8 reversible belt conveyors 14 for the proportioning area, 2 discharge belt conveyors 12, and 4 elevators 15 for the proportioning area. This configuration allows for flexible combination of four single and four mixed lines, and the four elevators 15 can be freely adjusted and used in combination. Combined with the control method of the integrated DCS / PLC system commonly used in this field, dynamic metering is basically realized, and continuous mixed production is supported. The operation time can be uninterrupted throughout the year, and automatic formula switching and precise flow control can be achieved.

[0029] In the temporary manual mixing area, a forklift can be used for manual feeding, which can handle situations where there is a sudden need for temporary mixing of a single raw material. Specifically, external dump trucks 1 can be used to unload the material on-site, and then the material can be manually mixed and crushed by a forklift before being directly conveyed and lifted to the pre-calcination buffer zone; or the two discharge belt conveyors 12 in the raw material metering and proportioning area can be used to transport the raw material in the silo to the temporary manual mixing area for piling and unloading, and then manually shoveled into the temporary feeding hopper 19 for mixing and crushing before being lifted to the pre-calcination buffer zone. This increases the flexibility of the production process and the ability to handle sudden material mixing.

[0030] like Figure 8 and Figure 9 As shown, the mixed raw materials are lifted to the pre-calcination buffer zone by four proportioning zone elevators 15. The pre-calcination buffer zone includes a conveyor belt 23 that works in conjunction with each proportioning zone elevator 15. Each conveyor belt 23 feeds materials to a corresponding buffer hopper 24. The buffer hopper 24 is used to receive and store the mixed raw materials. The buffer hopper 24 can ensure that the batch or rate fluctuations that may occur in the raw material metering and proportioning zone, as well as the continuous and stable feeding rhythm between the pre-calcination self-unloading hopper zone, can avoid the calcination process from being affected by a brief interruption of material or overfeeding.

[0031] like Figure 10 and Figure 11 As shown, the pre-calcination self-unloading hopper area includes a calcining furnace 25 arranged below the buffer silo 24. A hopper track 26 is provided above the calcining furnace 25. A movable rigid unloading hopper 27 is rolled on the hopper track 26. The buffer silo 24 discharges material to the distribution belt 28 through a vibrating feeder. The distribution belt 28 distributes material to the transition belt 30 through a three-way valve 29. The transition belt 30 conveys the raw material to the movable rigid unloading hopper 27. The vibrating feeder helps to ensure that the raw material is evenly and stably conveyed to the movable rigid unloading hopper 27.

[0032] The design of the pre-calcination self-unloading hopper area takes into account the high-temperature characteristics of the calcining furnace 25 and the possibility of fire escaping at the furnace opening. Therefore, the mobile rigid unloading hopper 27 is selected to ensure smooth material supply. The calcining furnace 25 has sixty-four material inlets. The mobile rigid unloading hopper 27 can be driven by a geared motor and controlled by an electric gate for the discharge hopper. Combined with a PLC system, it achieves automatic feeding positioning and interlocking of high and low level gauges, enabling fixed-point unloading at each inlet. The mobile rigid unloading hopper 27 can serve multiple feeding points, facilitating switching during equipment maintenance. It provides a larger buffer capacity than a simple belt conveyor, can handle longer periods of fluctuation, avoids the danger of occasional fire escaping from the furnace top and burning the belt, and is easier to seal with the material inlets of the calcining furnace 25. Furthermore, the mobile rigid unloading hopper 27 occupies minimal space above the furnace and can be easily moved for cleaning and maintenance of the calcining furnace 25 below.

[0033] like Figure 12 and Figure 13 As shown, the post-calcination cooling zone includes a discharge vibrating belt conveyor 31 used in conjunction with each of the calcining furnaces 25. The discharge vibrating belt conveyor 31 feeds material to a receiving belt conveyor 33 via a transition vibrating belt conveyor 32, and the receiving belt conveyor 33 discharges material to the post-calcination storage and shipping zone. It receives the high-temperature calcined material output from the calcining furnace 25 and utilizes the discharge vibrating belt conveyor 31 to continuously throw and tumble the material during transport, ensuring full contact with air and achieving high heat dissipation efficiency, thus realizing efficient cooling. During the transport process, the material temperature can be reduced to the safe temperature allowed by the post-calcination storage and shipping zone, achieving material cooling while completing long-distance horizontal transport tasks.

[0034] like Figure 14 and Figure 15 As shown, the post-calcination storage and shipping area includes a storage elevator 34 for lifting the raw materials conveyed by the material collection belt conveyor 33. A storage belt conveyor 35 is installed at the discharge end of the storage elevator 34, discharging material to the finished product silo 36. A bulk weighing device 38 is installed at the discharge port of the finished product silo 36, comprising a bulk loader and a weighing hopper. Two rows of finished product silos 36 are respectively equipped with the storage belt conveyors 35, and a reversible belt conveyor 37 for the shipping area is located between the two storage belt conveyors 35. The material from the storage elevator 34 is discharged onto the reversible belt conveyor 37 for the shipping area.

[0035] Specifically, the two rows of finished product bins 36 comprise a total of eight bins. After cooling, materials are collected via the material collection belt conveyor 33 and conveyed to the storage elevator 34. The storage elevator 34 then lifts the materials to the height of the finished product bins 36. This allows for targeted unloading at the top of the finished product bins 36, in conjunction with a three-way distributor, the reversible belt conveyor 37 in the shipping area, the storage belt conveyor 35, and a plow-type unloader, enabling selective storage of various finished materials in the eight bins. Each finished product bin 36 is equipped with high and low level gauges for real-time material level feedback, working in conjunction with a PLC system to achieve automatic feeding. During unloading, materials are loaded onto trucks via the bulk weighing device 38. The bulk level gauges are used for monitoring, and the low-position control of the bulk loading head helps prevent dust generation. Furthermore, the top of each finished product bin 36 is equipped with a dust collector to facilitate dust-free loading, and the loading quantity is re-weighed using a weighbridge. The loading process can be equipped with automated loading systems, including RFID vehicle identification at the entrance, gate barriers, traffic lights, and monitoring, to improve the automation level of the loading process.

[0036] This embodiment demonstrates the fully automated or semi-automated production process of the product through trial use in a negative electrode material precursor and high-tech carbon material project of a company in Rizhao City.

Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical application of the utility model, and to enable those skilled in the art to understand the utility model and design various embodiments with various modifications suitable for a particular purpose.
