Abstract
Description
Technical Field
[0001] This application relates to chemical equipment, and more specifically, to a feeding device and a lithium battery cathode material production system. Background Technology
[0002] In the production of ternary lithium-ion battery cathode materials, a feeder is used on the circulating production line. The original feeder had a flip-top feeding device. During feeding, material tends to accumulate. When the feeding cover closes, the original feeding device frequently pushes material out of the crucible, causing significant material loss. Residual material is also generated on the cover during operation; the impact of the cover causes material to scatter around the feeder, resulting in substantial waste.
[0003] In addition, the original structure is not conducive to precise control of the weight of the bowl. Often, even after feeding has stopped, material will still fall, causing the weight of the bowl to exceed the standard and affecting product quality (the control accuracy requirement is 100 grams).
[0004] Therefore, there is an urgent need to improve the feeding device used in the ternary lithium battery cathode material recycling line to avoid product waste and improve the packing accuracy. Utility Model Content
[0005] The purpose of this application is to provide a feeding device and a lithium battery cathode material production system, which aims to avoid product waste and improve the accuracy of filling the pan during the feeding process.
[0006] This utility model is implemented as follows:
[0007] In a first aspect, this utility model provides a feeding device, comprising:
[0008] The material feeding hopper has an opening at the top.
[0009] The feeding pipe is connected to the bottom of the feeding hopper. The feeding pipe has a bottom feeding port, and the diameter of the bottom feeding port is smaller than the inner diameter of the feeding pipe.
[0010] The insert plate feeding assembly includes a first inclined insert plate, a second inclined insert plate, a first driving member, and a second driving member. The side wall of the feeding tube above the bottom feeding port is provided with a first inclined insertion port that cooperates with the first inclined insert plate and a second inclined insertion port that cooperates with the second inclined insert plate. The first driving member is connected to the first inclined insert plate, and the second driving member is connected to the second inclined insert plate, so that the first driving member and the second driving member drive the first inclined insert plate and the second inclined insert plate to move respectively, so that the ends of the first inclined insert plate and the ends of the second inclined insert plate contact or move away, so as to seal or open the bottom feeding port.
[0011] In an optional embodiment, a fixedly installed support plate is also included, and both the first driving member and the second driving member are connected to the support plate.
[0012] In an optional embodiment, both the first driving member and the second driving member are cylinders. The cylinder has a fixed end and a driving end. The fixed end is connected to the support plate, and the driving end is connected to the first inclined plate or the second inclined plate.
[0013] In an optional embodiment, a dust cover is also included, which is installed on one side of the feed pipe and has an end opening that faces the bottom feed port.
[0014] In an optional implementation, the dust cover is connected to a suction pipe for connecting to an external vacuuming device.
[0015] In an optional implementation, there are multiple suction pipes.
[0016] In an optional implementation, the dust cover is detachably mounted on the support plate.
[0017] In an optional implementation, a receiving device is also included, having a top opening that faces the bottom discharge port during operation.
[0018] In an optional embodiment, the feeding hopper includes a wide opening section and a narrow opening section, the top of the narrow opening section is connected to the bottom of the wide opening section, and the inner diameter of the narrow opening section gradually decreases from top to bottom, and the top of the feeding pipe is connected to the bottom of the narrow opening section.
[0019] Secondly, this utility model provides a lithium battery cathode material production system, including the feeding device of any of the foregoing embodiments.
[0020] This invention offers the following advantages: It utilizes a feeding assembly comprising a first inclined plate, a second inclined plate, a first driving member, and a second driving member for feeding. A first inclined insertion port that mates with the first inclined plate and a second inclined insertion port that mates with the second inclined plate are positioned above the feeding port of the feeding tube. During operation, the first and second driving members respectively drive the first and second inclined plates to move, causing the ends of the first and second inclined plates to contact or move away, thereby sealing or opening the feeding port. This improved inclined feeding method eliminates material impact, preventing material from being ejected from the sagger and wasting material; it also effectively seals the feeding port, preventing leakage and improving the accuracy of material loading.

[0028] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "setup" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
[0029] like Figure 1As shown, this utility model embodiment provides a feeding device 100, including a feeding bin 110, a feeding pipe 120, and a plate feeding assembly 130. The feeding pipe 120 is connected to the bottom of the feeding bin 110 and has a bottom feeding port 121. The plate feeding assembly 130 controls the bottom feeding port 121 to be sealed or opened.
[0030] The top of the feeding hopper 110 is open, and the material is fed from the top opening of the feeding hopper 110 into the feeding pipe 120. When feeding is required, the bottom feeding port 121 is opened by the insert feeding assembly 130 to feed the material.
[0031] In some embodiments, the feeding hopper 110 includes a wide-mouth section 111 and a narrow-mouth section 112. The top of the narrow-mouth section 112 is connected to the bottom of the wide-mouth section 111, and the inner diameter of the narrow-mouth section 112 gradually decreases from top to bottom. The top of the feeding pipe 120 is connected to the bottom of the narrow-mouth section 112. The feeding hopper 110 has a funnel-like shape, which facilitates feeding and discharging. The larger inner diameter at the top of the feeding hopper 110 facilitates feeding, while the smaller inner diameter at the bottom facilitates control of the discharge rate. The wide-mouth section 111 and the narrow-mouth section 112 can be integrally formed, and the specific material is not limited; they can be made of stainless steel or alloy.
[0032] Please refer to Figure 1 , Figure 2 and Figure 3 The diameter of the bottom discharge port 121 is smaller than the inner diameter of the discharge pipe 120, which makes it easier for the insert plate in the insert plate discharge assembly 130 to better cover the smaller bottom discharge port 121 and seal the bottom discharge port 121.
[0033] Furthermore, the insert plate feeding assembly 130 includes a first inclined insert plate 131, a second inclined insert plate 132, a first driving member 133, and a second driving member 134. A first inclined insertion port 122 that mates with the first inclined insert plate 131 and a second inclined insertion port 123 that mates with the second inclined insert plate 132 are provided on the side wall of the feeding pipe 120 located above the bottom feeding port 121. The first driving member 133 is connected to the first inclined insert plate 131, and the second driving member 134 is connected to the second inclined insert plate 132. During operation, the first driving member 133 and the second driving member 134 drive the first inclined insert plate 131 and the second inclined insert plate 132 to move, causing the ends of the first inclined insert plate 131 and the second inclined insert plate 132 to contact or move away from each other, thereby sealing or opening the bottom feeding port 121.
[0034] Specifically, when the ends of the first inclined plate 131 and the second inclined plate 132 are in contact, the bottom discharge port 121 can be closed. When the ends of the first inclined plate 131 and the second inclined plate 132 are not in contact, the bottom discharge port 121 is opened. The size of the opening can be controlled by adjusting the distance between the ends of the first inclined plate 131 and the second inclined plate 132, which facilitates the control of the discharge rate and improves the accuracy of the filling metering. When the discharge flow rate requirement is small, only one drive component can be activated.
[0035] Specifically, the first inclined insertion plate 131 and the second inclined insertion plate 132 can be arranged symmetrically, but are not limited thereto. The shape and size of the first inclined insertion port 122 cooperate with the first inclined insertion plate 131, so that the first inclined insertion plate 131 can move within the first inclined insertion port 122, such as moving obliquely upward or obliquely downward. Similarly, the shape and size of the second inclined insertion port 123 cooperate with the second inclined insertion plate 132, so that the second inclined insertion plate 132 can move within the second inclined insertion port 123, such as moving obliquely upward or obliquely downward.
[0036] The driving method of the first driving component 133 and the second driving component 134 is not limited; they can drive the first inclined plate 131 and the second inclined plate 132 to move. The tilt angle of the first inclined plate 131 and the second inclined plate 132 should not be too large, such as 45°. An excessively large tilt angle will affect the sealing effect on the bottom discharge port 121. The tilt angle can be zero, in which case the first inclined plate 131 and the second inclined plate 132 can move in parallel, which can better seal the bottom discharge port 121.
[0037] In some embodiments, the feeding device 100 further includes a fixedly installed support plate 140. The first driving member 133 and the second driving member 134 are both connected to the support plate 140. The support plate 140 can be fixed to the outer wall of the feeding pipe 120 to facilitate the installation of the first driving member 133 and the second driving member 134. Both the first driving member 133 and the second driving member 134 can be cylinders. Each cylinder has a fixed end and a driving end. The fixed end is connected to the support plate 140, and the driving end is connected to the first inclined plate 131 or the second inclined plate 132. The cylinder is connected to a connecting rod, and the extension and retraction of the connecting rod controls the movement of the first inclined plate 131 or the second inclined plate 132. When the connecting rod extends, the bottom feeding port 121 is sealed; when the connecting rod retracts, the bottom feeding port 121 is opened.
[0038] It should be noted that the first drive unit 133 and the second drive unit 134 can work independently, each connected to the automatic control system, or can be operated manually.
[0039] In some embodiments, the feeding device 100 further includes a receiving device 160 that cooperates with the bottom feeding port 121. The receiving device 160 has a top opening, and during operation, the top opening of the receiving device 160 faces the bottom feeding port 121, enabling it to receive material output from the bottom feeding port 121. Specifically, the receiving device 160 can be a sagger, but is not limited thereto. The shape of the receiving device 160 is not limited and can be a cuboid shape with a top opening.
[0040] In some embodiments, the feeding device 100 further includes a dust cover 150, which is installed on one side of the feeding pipe 120. The dust cover 150 has an end opening facing the bottom feeding port 121, and can collect dust generated during the discharge process. The end opening of the dust cover 150 can cover most of the area near the feeding pipe 120, and part of the receiving device 160 can be accommodated in the inner cavity of the dust cover 150 to improve the dust collection effect.
[0041] Furthermore, the dust cover 150 is connected to a suction pipe 151, which connects to an external dust collection device. The external dust collection device generates suction to collect the dust generated during the discharge process into the dust cover 150 and then output it to the external dust collection device through the suction pipe 151. The number of suction pipes 151 is not limited and multiple pipes can be used to fully remove dust and prevent it from entering other areas.
[0042] Specifically, the external vacuuming device can be an existing vacuum cleaner, and the specific model is not limited.
[0043] Furthermore, the dust cover 150 is detachably installed on the support plate 140 and can be fixed by bolts or other fasteners, and can be removed and installed. Specifically, the dust cover 150 can be divided into two parts, which are installed separately for easy removal.
[0044] This utility model embodiment also provides a lithium battery cathode material production system, including the feeding device 100 provided in this utility model embodiment, and may also include a lithium battery cathode material reaction preparation unit, forming a complete production system.
[0045] It should be noted that, where there is no conflict, the features in the embodiments of this application can be combined with each other.
[0046] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
