Description

Technical Field

[0002] With the popularization of electric vehicles and battery energy storage, the lithium battery industry continues to expand, making electrode recycling and regeneration an urgent need. Currently, there is no unified and mature process for electrode recycling. The raw materials entering the thermal decomposition step can be either sheet or powder, which places wide demands on the feeding range and performance of the feeding equipment. Existing automatic feeding systems use a discharge shut-off valve plus a feeding screw, where the screw measures the amount of material fed. However, due to the different physical properties and bulk densities of powder and sheet, the feeding amount per unit time varies greatly for the same set of equipment. Even when the existing equipment is adjusted to its functional limits, it cannot meet the required feeding amount for the process. Therefore, existing equipment systems are usually only suitable for supplying one type of raw material (powder or sheet) and cannot meet the feeding task with process modifications.

[0027] In one embodiment, such as Figure 1 As shown, a valve-controlled automatic feeding system is provided, including a storage device 100, a venting device 200, a stirring device 300, a weighing device 400, a feeding device 500, and a feeding device 600.

The venting device 200 is located at the top of the storage device 100. The feeding device 500 includes a feeding ball valve 501, one end of which is connected to the material stirring plate 301 via a material conveying device 1, and the other end of which is connected to the feeding device 600 via the material conveying device 1.

[0028] It should be noted that the storage device 100 is a storage silo, and its storage capacity can be set according to actual needs, preferably 1500L. The storage device 100 is made of stainless steel. Copper and zinc elements are prohibited in the production process of lithium iron phosphate powder, and the iron content is strictly controlled. The material conveying device 1 is a stainless steel pipeline.

[0029] In some specific implementations, such as Figure 1 As shown, the valve-controlled automatic feeding system also includes a vacuum feeding device 700, which is connected to the top of the storage device 100 via the material conveying device 1.

[0030] It should be noted that the raw materials are conveyed to the storage device 100 through the material conveying device 1 by the negative pressure generated by the vacuum feeding device 700. The raw materials can be flakes and / or powders.

[0031] In some specific implementations, such as Figure 1As shown, the valve-controlled automatic feeding system also includes a kiln body 800, one end of which is connected to the feeding device 600.

[0032] It should be noted that the material is conveyed into the kiln body via a feed screw conveyor to complete the material conveying process.

[0033] In some specific implementations, such as Figure 1 As shown, the stirring device 300 also includes a material stirring motor 302 and a material stirring motor gearbox 303; one end of the material stirring motor gearbox 303 is connected to the material stirring plate 301, and the other end of the material stirring motor gearbox 303 is connected to the material stirring motor 302.

[0034] It should be noted that the material mixing motor gearbox 303 and the material mixing motor 302 are located at the bottom of the storage device 100 and are used to jointly drive the material mixing plate 301 to mix different batches of materials evenly and achieve the effect of diversifying the types of raw material feeding.

[0035] In some specific implementations, such as Figure 1 As shown, the venting device 200 includes a venting hole 201 and a venting valve 202; one end of the venting valve 202 is connected to the venting hole 201, and the other end of the venting valve 202 is connected to the storage device 100 through the first connecting flange 2. A venting valve valve 7 is provided on the side end of the venting valve 202.

[0036] It should be noted that when the vacuum feeding device 700 is started, the vent valve 7 is opened to open the vent valve 202, which is used to remove the air in the storage hopper after the raw material enters the storage hopper.

[0037] In some specific implementations, such as Figure 1 As shown, the feeding device 600 includes a feeding screw gearbox 601, a feeding screw motor 602, and a feeding screw 603; one end of the feeding screw gearbox 601 is connected to the feeding screw motor 602, and the other end of the feeding screw gearbox 601 is connected to one end of the feeding screw 603, and the other end of the feeding screw 603 is connected to the kiln body 800; the top of the feeding screw 603 is provided with a feed inlet 3, and the feed inlet 3 is connected to the other end of the discharge ball valve 501 through the material conveying device 1.

[0038] It should be noted that the feed screw gearbox 601 and the feed screw motor 602 are located at one end of the feed screw 603 and are used to jointly drive the feed screw 603 to convey the material into the kiln body 800.

[0039] In some specific implementations, such as Figure 1As shown, the weighing device 400 includes a first weighing element 401 and a second weighing element 402; the first weighing element 401 and the second weighing element 402 are symmetrically arranged at the bottom end of the material mixing plate 301.

[0040] It should be noted that the weighing device 400 is used to monitor the weight of the material in the storage device 100 in real time. When the weight of the material in the storage device 100 reaches the upper limit weight set by the HMI (Human Machine Interface), the PLC (Programmable Logic Controller) sends a weight reach electrical signal, and the vacuum feeding device 700 stops feeding, completing the feeding step.

[0041] In some specific implementations, such as Figure 1 As shown, the valve-controlled automatic feeding system also includes: one end of the feeding ball valve 501 is connected to the material conveying device 1 through the second connecting flange 4, the other end of the feeding ball valve 501 is connected to the material conveying device 1 through the third connecting flange 5, and a feeding ball valve valve 6 is provided on the side end of the feeding ball valve 501.

[0042] It should be noted that the feeding ball valve 501 opens and closes according to the opening and closing time set on the HMI, thereby controlling and adjusting the feeding amount to achieve automatic feeding. Its specific opening and closing time program is as follows: Figures 2-3 As shown, the input box for setting the opening and closing time of the feeding ball valve 501 via the HMI screen is as follows: Figure 4 As shown.

[0043] The working principle of this application is as follows: When the valve-controlled automatic feeding system is operating normally, the weighing device 400 monitors the weight of the material in the storage device 100 in real time. If the weighing device 400 detects that the weight of the material in the storage device 100 has not reached the upper limit of the weight set by the HMI, that is, the storage device 100 is empty or not full, which is a material shortage state. At this time, the PLC control system sends a material request signal to the vacuum feeding device 700, the vacuum feeding device 700 starts, and at the same time opens the vent valve 202 on the storage device 100. After the raw material enters the storage device 100, the air squeezed by the material is discharged through the vent 201. The raw material enters the storage device 100 through the stainless steel pipeline due to the negative pressure formed by the vacuum feeding device 700. The weighing device 400 monitors the weight of the material in the storage device 100 in real time. When the weight of the material in the storage device 100 reaches the upper limit of the weight set by the HMI, the PLC sends a weight reach electrical signal, and the vacuum feeding device 700 stops feeding. The material feeding process is completed. 0-200 seconds after feeding, the material mixing motor 302 is started to evenly mix different batches of material, ensuring a uniform flow from the storage device 100 and preventing localized material accumulation and bridging. A stainless steel pipe connects to the discharge ball valve 501 to control the feed rate. If the system is ready for discharge, the feeding screw 603 is started directly. The discharge ball valve 501 is then opened and closed according to the opening and closing times set on the HMI, thus regulating the feed rate to the feeding screw 603. The material is then conveyed into the kiln body 800 via the feeding screw 603, completing the material conveying process. Simultaneously, the weighing device 400 monitors the weight of the material in the storage device 100 in real time. When the material weight reaches the lower limit set by the HMI, the material mixing motor 302 and the feeding screw 603 stop running after a 0-200 second delay, and the discharge ball valve 501 stops running after another 0-200 seconds, remaining stationary. The vent valve 202 is then closed, completing the discharge process.

[0044] The aforementioned valve-controlled automatic feeding system includes a storage device, a venting device, a mixing device, a weighing device, a feeding device, and a delivery device. The mixing device includes a material mixing plate positioned between the storage device and the weighing device, at the bottom of the storage device. The venting device is located at the top of the storage device. The feeding device includes a feeding ball valve, one end of which is connected to the material mixing plate via a material conveying device, and the other end is connected to the delivery device via the same device. The weighing device allows for real-time monitoring of the material weight in the storage device, ensuring the feeding quantity meets process requirements. The mixing device agitates the material until the feeding conditions are met, ensuring that the required feeding quantity is maintained even when the process changes, such as when raw materials are switched between flakes and powder. This allows for diversification of feeding types and utilizes the feeding ball valve to achieve a larger feeding space, fulfilling the process requirements for diverse raw materials.

For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described.
