[0027] Example Please see Figure 1 , Figure 1The diagram shown is a structural schematic of the feeding device 200 provided in this embodiment.

[0028] The feeding device 200 provided in this embodiment includes a feeding device 100, a material storage tank 210, and a material delivery tank 220. The feeding device 100 provides space for unpacking the material bags and transports the obtained material to the material storage tank 210 in an isolated environment to collect and store the packaging bags. The material storage tank 210 stores the material and transports it to the material delivery tank 220 as needed. The material delivery tank 220 transports the material to the feeding device.

[0029] The feeding device 200 provided in this embodiment can be used to transport lithium replenishing agents. Specifically, the packaging bags of the lithium replenishing agents are removed from the feeding device 100, and the packaging bags are collected and stored. The unpacked lithium replenishing agents are then transported to the material storage tank 210. The material storage tank 210 stores the lithium replenishing agents and, as needed, transports the stored lithium replenishing agents to the material dispatch tank 220. The material dispatch tank 220 then transports the received lithium replenishing agents to the battery production device to prepare lithium batteries using the lithium replenishing agents.

[0030] Please refer to the following: Figure 2 , Figure 2 The diagram shown is a structural schematic of the feeding device 100.

[0031] In this embodiment, the feeding device 100 includes a dust removal bin 110, a feeding bin 120, and a collection bin 130. The dust removal bin 110 has a first door 111 that, when open, allows material to enter the bin. The dust removal bin 110 is used to remove dust from material packages entering it. The feeding bin 120 is connected to the dust removal bin 110 via a second door 121. When open, the second door 121 allows dust-removed material packages to enter the feeding bin 120 from the dust removal bin 110. The feeding bin 120 opens the material packages and transports the opened material to the material storage tank 210. The collection bin 130 is connected to the feeding bin 120 via a third door 131 that, when open, allows opened packaging bags to enter the collection bin 130 for collection.

[0032] In practical applications, after opening the first door 111, the material package is placed inside the dust removal chamber 110 for dust removal, i.e., removing impurities adhering to the surface of the material package. During the dust removal process, the first door 111 is closed to prevent air from entering the dust removal chamber 110, providing an isolated environment for the dust removal process; the second door 121 is closed to prevent impurities from entering the feeding chamber 120. After dust removal is completed, the second door 121 is opened, and the material package is transferred to the feeding chamber 120. With the second door 121 and the third door 131 closed, the material package is opened, i.e., the packaging bag of the material package is removed. After the bag opening is completed, the material is conveyed from the feeding chamber 120 to the material storage tank 210. After the material conveying in the feeding chamber 120 is completed, the third door 131 is opened, and the packaging bag is transferred to the collection chamber 130 for collection and storage.

[0033] Please refer to the following: Figure 3 , Figure 4 , Figure 5 and Figure 6 , Figure 3 The diagram shown is a structural schematic of the dust collection chamber 110 from one perspective. Figure 4 The diagram shown is a structural schematic of the dust collection chamber 110 from another perspective. Figure 5 The diagram shown is a structural schematic of the dust collection chamber 110 from another perspective. Figure 6 The diagram shows a partial structural diagram of the interior of the dust removal chamber 110.

[0034] In this embodiment, the dust collection chamber 110 is equipped with a blowing component 112, which is selectively connected to an external air source for blowing and dust removal of material packages within the dust collection chamber 110. In this embodiment, the blowing chamber is located on the side of the dust collection chamber 110 opposite to the first door 111. A first perforated plate 113 is provided at the bottom of the dust collection chamber 110, and a dust collection port 114 communicating with the outside is provided below the first perforated plate 113.

[0035] A material fence 115 for holding material packages is rotatably mounted on the first perforated plate 113. The material fence 115 has an opening. A wind cap 116 is provided on the top of the material fence 115. The wind cap 116 is selectively connected to an external air source through a pipe to drive the material fence 115 to rotate.

[0036] In practice, the surface of the first perforated plate 113 is provided with a rotatable rotating disk 1131, and the material fence 115 is disposed on the rotating disk 1131. The bottom of the material fence 115 has a second perforated plate 1153 for supporting the material package. In practical applications, the air cap 116 is selectively connected to an external nitrogen source through a pipeline. When nitrogen is supplied to the air cap 116 through an external nitrogen source, the air cap 116 can drive the material fence 115 and the rotating disk 1131 to rotate on the first perforated plate 113.

[0037] In this embodiment, a first cylinder 117 and a second cylinder 118 are provided on the outer wall of the dust collection chamber 110 opposite to the first door 111. The telescopic end of the first cylinder 117 is provided with a first stop 1171 that extends into the dust collection chamber 110, and the telescopic end of the second cylinder 118 is provided with a second stop 1181 that extends into the dust collection chamber 110. A third cylinder 119 and a fourth cylinder 1192 are provided on the outer wall of the dust collection chamber 110 between the first door 111 and the first cylinder 117. The telescopic end of the third cylinder 119 is provided with a third stop 1191 that extends into the dust collection chamber 110, and the telescopic end of the fourth cylinder 1192 is provided with a fourth stop 1193 that extends into the dust collection chamber 110. Through the coordinated action of the first cylinder 117, the second cylinder 118, the third cylinder 119 and the fourth cylinder 1192, the rotating material fence 115 can be locked and limited so that the opening of the material fence 115 faces the first door 111 or the second door 121.

[0038] In practical applications, when the feeding equipment 200 starts feeding, the first cylinder 117 extends from its retracted state, and the first stop block 1171 gradually extends into the dust collection chamber 110. The nitrogen source supplies nitrogen to the air cap 116 through pipelines. The nitrogen is required to have a dew point of -60℃ or lower. The air cap 116 drives the material fence 115 to start rotating, and at the same time, the dust collection port 114 opens, and the nitrogen inside the dust collection chamber 110 is discharged through the dust collection port 114.

[0039] A first limiting block 1151 and a second limiting block 1152 are provided on both the side where the opening of the material fence 115 is located and the side opposite to the opening. The length of the first limiting block 1151 protruding from the material fence 115 is greater than the length of the second limiting block 1152 protruding from the material fence 115. When the wind cap 116 drives the material fence 115 to rotate until the first limiting block 1151 contacts the side of the first stop block 1171, the material fence 115 stops rotating due to the stop of the first stop block 1171. At this time, the second cylinder 118 begins to extend from the retracted state, and the second stop block 1181 gradually extends into the dust collection chamber 110. When the second stop block 1181 contacts the side of the second limiting block 1152, it stops extending further. At this time, the first stop block 1171 and the second stop block 1181 together lock the material fence 115.

[0040] When the first stop 1171 and the second stop 1181 lock the material fence 115, the vent 116 stops the nitrogen input, and the dust collector port 114 closes. At this time, the opening of the material fence 115 faces the first door 111. In this state, the first door 111 is open, and material packages are placed on the second mesh plate 1153 of the material fence 115 by manual or other automated conveying devices. Afterward, the first door 111 closes, isolating the internal space of the material silo from the outside.

[0041] After the first door 111 closes, the first cylinder 117 and the second cylinder 118 retract, causing the first stop block 1171 and the second stop block 1181 to release the locking of the material fence 115. The hood 116 begins to supply nitrogen, causing the material fence 115 to rotate, and the blowing component 112 begins to blow nitrogen into the dust collection chamber 110, directed towards the material fence 115. During the rotation of the material fence 115, the surface of the material bag is cleaned and dust is removed. Impurities on the surface of the material bag are drawn away by the dust collection port 114 through the second mesh plate 1153 and the first mesh plate 113.

[0042] In practical applications, the purging time can be specifically set. When the purging time is reached, the purging component 112 stops blowing nitrogen, the third cylinder 119 extends from its retracted state, and the third stop block 1191 gradually penetrates into the dust collection chamber 110. When the material fence 115 rotates until the first limit block 1151 contacts the third stop block 1191, the material fence 115 stops rotating due to the stop of the third stop block 1191. At this time, the fourth cylinder 1192 extends from its retracted state, and the fourth stop block 1193 gradually extends into the dust collection chamber 110. When the fourth stop block 1193 contacts the side of the second limit block 1152, it stops extending further. At this time, the third stop block 1191 and the fourth stop block 1193 together lock the material fence 115. In this state, the hood 116 stops supplying nitrogen, the dust collection port 114 closes, and the opening of the material fence 115 faces the second door 121.

[0043] Please refer to the above. Figure 7 , Figure 8 and Figure 9 , Figure 7 The diagram shown is a structural schematic of the feeding hopper 120 from one perspective. Figure 8 The diagram shown is a structural schematic of the feeding hopper 120 from another perspective. Figure 9 The diagram shown is a cross-sectional view of the feeding hopper 120.

[0044] In this embodiment, the feeding hopper 120 is equipped with an operating glove 122 and a transparent observation window 123. The operating glove 122 is used for operators to transfer material packages between the dust removal hopper 110 and the feeding hopper 120, to open material packages in the feeding hopper 120, and to transfer packaging bags between the feeding hopper 120 and the collection hopper 130. The transparent observation window 123 allows operators to observe the internal condition of the feeding device 100.

[0045] With the material fence 115 locked by the third stop 1191 and the fourth stop 1193, the second door 121 is opened. The operator observes through the transparent observation window 123 and transfers the material package in the material fence 115 to the feeding bin 120 through the operating gloves 122.

[0046] In this embodiment, a conical hopper 124 is provided at the bottom of the feeding hopper 120. The conical hopper 124 is connected to the feeding hopper 120 and the two are flexibly connected. A screen 1241 for holding material bags is provided at the top of the conical hopper 124. The conical hopper 124 is used to transport the opened material to the downstream device. The conical hopper 124 and the feeding hopper 120 are connected by a silicone flexible connection, which can block the transmission of vibration between the two and prevent air from passing through, ensuring the isolation of the internal space of the feeding hopper 120 and the conical hopper 124 from the outside world.

[0047] The feeding hopper 120 is equipped with an air blowing assembly 125, which is selectively connected to an external air source for blowing gas into the feeding hopper 120. The portion of the air blowing assembly 125 that extends into the feeding hopper 120 is equipped with a dust filter 1251, and the air blowing assembly 125 is also equipped with a cleaning port 1252 for cleaning the dust filter 1251.

[0048] A first pneumatic valve 1242 is installed at the bottom of the cone hopper 124. The first pneumatic valve 1242 is connected to the material storage tank 210 via a pipeline, and a second pneumatic valve 1243 is also installed at the end of this pipeline near the material storage tank 210. After the material bag is placed on the screen 1241, the second door 121 is closed, and the operator removes the packaging bag of the material bag. Then, the air blowing assembly 125 begins to blow nitrogen into the feeding hopper 120, and the first pneumatic valve 1242 and the second pneumatic valve 1243 are opened, allowing the material in the feeding hopper 120 to enter the material storage tank 210 through the cone hopper 124. During this process, nitrogen needs to be supplied to the pipeline between the cone hopper 124 and the material storage tank 210 to adjust the material-to-gas ratio and prevent pipeline blockage.

[0049] Please refer to the following: Figure 10 and Figure 11 , Figure 10 The image shown is a schematic diagram of part of the bottom structure of the cone 124 from one perspective. Figure 12 The diagram shown is a partial structural diagram of the bottom of the cone 124 from another perspective.

[0050] In this embodiment, a magnetic rod 126 for removing magnetic substances from the material is provided at the bottom of the cone hopper 124, and a vibrator 127 is provided on the cone hopper 124. During the process of the material being conveyed from the cone hopper 124 to the material storage tank 210, the material passes through the magnetic rod 126, thereby removing the magnetic substances. Furthermore, during this process, the vibrator 127 can drive the cone hopper 124 to vibrate to assist in the material discharge.

[0051] In fact, the cone hopper 124 has symmetrically arranged fixed seats 128 on both sides of its bottom. The magnetic rod 126 passes through the cone hopper 124 and its two ends are located within the two fixed seats 128. The two fixed seats 128 are hollow structures, with airbags inside for holding or releasing the magnetic rod 126. The two fixed seats 128 also have inflation ports 1281 for inflating the airbags. One end of the magnetic rod 126 is connected to a guide rod 1261 extending out of one of the fixed seats 128. The guide rod 1261 is made of stainless steel to prevent magnetism from adhering. The other fixed seat 128 is provided with a scraper 1282. The end of the magnetic rod 126 away from the guide rod 1261 passes through the scraper 1282 and is connected to the fixed rod 1262. The scraper 1282 and the corresponding fixed seat 128 are spaced apart, forming a scraping gap. A collection box 129 can be arranged below the scraping gap.

[0052] Furthermore, a scraping cylinder 1283 is installed on the fixed base 128, and the telescopic end of the scraping cylinder 1283 is connected to the fixed rod 1262. When the feeding equipment 200 operates in the magnetic rod 126 cleaning mode, the scraping cylinder 1283 drives the magnetic rod 126 to pass through the scraper 1282 in a direction away from the fixed base 128 via the fixed rod 1262. During this process, the magnetic material adsorbed on the surface of the magnetic rod 126 is scraped off by the scraper 1282 and falls into the collection box 129 below through the scraping gap.

[0053] During the material conveying process through the conical hopper 124, the air inlet 1281 inflates the air bladder inside the fixed base 128, causing the air bladder to tightly grip the magnetic rod 126. In reality, the portion of the magnetic rod 126 corresponding to the air bladder is not magnetic. Furthermore, during the scraping process to remove magnetic material from the surface of the magnetic rod 126, the magnetic material adhering to the magnetic area of ​​the magnetic rod 126 is first pushed to the non-magnetic area by the scraper 1282, and some of it falls into the collection box 129. As the magnetic rod 126 continues to extend, the magnetic material is further pushed to the position of the connecting guide rod 1261 and falls entirely into the collection box 129.

[0054] Understandably, the air blowing assembly 125 can perform a period of blowing before scraping off the magnetic material to initially remove dust from the surface of the magnetic rod 126. To facilitate the rapid removal of the magnetic material, the cross-section of the guide rod 1261 in this embodiment is elliptical. In another embodiment, a surface structure such as a Teflon coating can also be provided on the surface of the guide rod 1261.

[0055] In this embodiment, the dust filter 1251 is a hollow cylindrical rod with a surface arranged with dense mesh. The dust filter 1251 is also connected to a cleaning port 1252 provided on the air blowing assembly 125. When the air blowing assembly 125 stops blowing, the cleaning port 1252 cleans and removes dust from the dust filter 1251. After dust removal, the air blowing assembly 125 performs intermittent blowing several more times to ensure that no dust adheres to the surface of the dust filter 1251.

[0056] Please refer to the following: Figure 12 and Figure 13 , Figure 12 The diagram shown is a structural schematic of the collection chamber 130. Figure 13 The diagram shown is a cross-sectional view of the collection chamber 130.

[0057] In this embodiment, the collection bin 130 includes an upper bin 132 and a lower bin 133 that are slidably fitted together. The upper bin 132 is connected to the feeding bin 120 via a third door 131. An upper insert plate 134 is slidably disposed at the bottom of the upper bin 132, which is used to extend or retract under force. A lower insert plate 135 is slidably disposed at the top of the lower bin 133, which is also used to extend or retract under force. After the feeding bin 120 completes the feeding of materials to the material storage tank 210, the air blowing assembly 125 stops blowing air, the third door 131 opens, and the operator, wearing gloves, places the packaging bag into the upper bin 132.

[0058] The upper insert plate 134 and the lower insert plate 135 are connected at the same end by a snap fastener 136. The collection chamber 130 is also provided with a drive assembly 137. The drive assembly 137 cooperates with the snap fastener 136 to drive the snap fastener 136 to extend or retract the upper insert plate 134 and the lower insert plate 135 into the collection chamber 130, so that the packaging bag on the surface of the upper insert plate 134 falls into the lower chamber 133.

[0059] A compression mechanism 138 is provided on the upper compartment 132 or the lower compartment 133. The compression mechanism 138 is used to compress the packaging bag that falls into the lower compartment 133. In practical applications, after the packaging bag is placed into the upper compartment 132, the drive component 137 operates, pulling the upper insert plate 134 and the lower insert plate 135 out of the collection compartment 130 via the buckle 136, causing the packaging bag on the upper insert plate 134 to fall into the lower compartment 133. Then, the compression mechanism 138 operates to compress the packaging bag to save space. After compression is completed, the compression mechanism 138 resets, and the drive component 137 drives the upper insert plate 134 and the lower insert plate 135 to re-enter the collection compartment 130.

[0060] Please refer to the following: Figure 14 and Figure 15 , Figure 14 The diagram shown is a structural schematic of the material storage tank 210. Figure 15The diagram shown is a structural schematic of the material delivery tank 220.

[0061] The material storage tank 210 is equipped with a negative pressure pipeline 211 connected to an external negative pressure device. The negative pressure pipeline 211 is used to create negative pressure in the material storage tank 210 under the action of the negative pressure device, so as to draw the material in the feeding bin 120 into the material storage tank 210.

[0062] In this embodiment, the negative pressure pipeline 211 is connected to the top of the discharge storage tank at both ends. One end of the negative pressure pipeline 211 is connected to a negative pressure device and is equipped with a third pneumatic valve 2111, while the other end is open and equipped with a fourth pneumatic valve 2112. In fact, the third pneumatic valve 2111 is opened during the process of transporting the material in the feeding hopper 120 to the material storage tank 210.

[0063] The material storage tank 210 is also provided with a first air supply port 212 and a first pressure detection element 213. The first air supply port 212 is selectively connected to an external air source and is used to supply gas into the material storage tank 210. The first pressure detection element 213 is used to detect the pressure inside the material storage tank 210.

[0064] After the material storage tank 210 is filled, the first air inlet 212 starts to blow nitrogen into the material storage tank 210. It is linked with the first pressure detection element 213. When the pressure in the material storage tank 210 reaches the set pressure, the first air inlet 212 closes, so that the material storage tank 210 is filled with nitrogen, which plays a role in isolating the external environment.

[0065] The material storage tank 210 actually has a feeding hopper 214 and a storage hopper 215 distributed vertically. The feeding hopper 214 is connected to the conical hopper 124 of the feeding device 100 via a pipeline. A filter device is installed inside the feeding hopper 214 to prevent material from being discharged during negative pressure feeding and depressurization. The storage hopper 215 is used to store materials and is connected to the material delivery tank 220 via a pipeline.

[0066] A conveyor 216, a fifth pneumatic valve 217, and a sixth pneumatic valve 218 are sequentially installed on the pipeline between the storage silo 215 and the material delivery tank 220. The conveyor 216 is used to transport the material in the storage silo 210 to the material delivery tank 220. The fifth pneumatic valve 217 and the sixth pneumatic valve 218 are installed at intervals.

[0067] The material storage tank 210 is equipped with a first weight detection element 219, which is used to detect the weight of the material storage tank 210. The material delivery tank 220 is equipped with a second weight detection element 221, which is used to detect the weight of the material delivery tank 220.

[0068] In this embodiment, an exhaust pipe 230 is also provided between the material storage tank 210 and the material delivery tank 220. One end of the exhaust pipe 230 is connected to the material storage tank 210 through a seventh pneumatic valve 231, and the other end is selectively connected to the material delivery tank 220. Specifically, the material delivery tank 220 is provided with an adjusting cylinder 222. The rodless chamber of the adjusting cylinder 222 is selectively connected to the material delivery tank 220 through an eighth pneumatic valve 223, and the end of the exhaust pipe 230 away from the material storage tank 210 is connected to the rodless chamber of the adjusting cylinder 222.

[0069] When the material storage tank 210 starts discharging, it needs to be depressurized first. When the storage silo 215 begins to depressurize, the fourth pneumatic valve 2112 opens, and the sixth pneumatic valve 218, the eighth pneumatic valve 223, and the second pneumatic valve 1243 also open. The regulating cylinder 222 extends and retracts once, which can scrape off the powder accumulated at the position of the eighth pneumatic valve 223 and push the remaining powder into the material delivery tank 220. After the depressurization is completed, the material storage tank 210 starts discharging, the fifth pneumatic valve 217 opens, and the conveyor 216 runs to send the material in the storage silo 215 into the material delivery tank 220.

[0070] During this process, the weight reduction of the material storage tank 210 can be measured by the first weight detection element 219, which represents the amount of material transported from the material storage tank 210 to the material delivery tank 220. The weight increase of the material delivery tank 220 can be measured by the second weight detection element 221. Since the material will be suspended after entering the material delivery tank 220, and some material will return to the material storage tank 210 through the exhaust pipe 230, it is more accurate to calculate the amount of material input into the material delivery tank 220 based on the detection result of the first weight detection element 219. Furthermore, in this embodiment, the two ends of the exhaust pipe 230 are softly connected to the material storage tank 210 and the adjusting cylinder 222, respectively, which can prevent the exhaust pipe 230 from affecting the weight of the material storage tank 210 and the material delivery tank 220.

[0071] During the material transfer process from the material storage tank 210 to the material delivery tank 220, the gas inside the material delivery tank 220 enters the material storage tank 210 through the exhaust pipe 230, eliminating the need for an additional pressure relief device on the material delivery tank 220 and achieving pressure balancing. After the material transfer is complete, the conveyor 216 is shut off, and the fifth pneumatic valve 217, the sixth pneumatic valve 218, the seventh pneumatic valve 231, and the fourth pneumatic valve 2112 are closed. Meanwhile, the first air supply port 212 blows nitrogen into the material storage tank 210, filling it with nitrogen for isolation and protection. Finally, the regulating cylinder 222 extends and retracts once, and the eighth pneumatic valve 223 closes.

[0072] The material delivery tank 220 is equipped with a second air supply port 224 and a second pressure detection element 225. The second air supply port 224 is selectively connected to an external air source and is used to supply gas into the material delivery tank 220. The second pressure detection element 225 is used to detect the pressure inside the material delivery tank 220. The material delivery tank 220 is equipped with a feeding pipeline 226 for supplying materials to the material receiving device. The feeding pipeline 226 is equipped with a third air supply port 227 and a third pressure detection element 228. The third air supply port 227 is selectively connected to an external air source and is used to supply gas into the feeding pipeline 226. The third pressure detection element 228 is used to detect the pressure inside the feeding pipeline 226.

[0073] A ninth pneumatic valve 2261 is installed at one end of the feeding pipe connected to the material delivery tank 220, and a tenth pneumatic valve 2262 is installed at the other end connected to the material receiving device. A third air inlet 227 and a third pressure detection element 228 are located between the ninth and tenth pneumatic valves 2261 and 2262. An air blowing port is installed at the bend of the feeding pipe 226, located between the ninth and tenth pneumatic valves 2261 and 2262. Before the material delivery tank 220 delivers material to the material receiving device through the feeding pipe 226, nitrogen gas is blown into the feeding pipe 226 through the air blowing port until the pressure value detected by the third pressure detection element 228 reaches the set pressure, and the pressure is stabilized for a period of time to ensure that the feeding pipe 226 is free from damage and leakage.

[0074] Then, the tenth pneumatic valve 2262 opens, depressurizing the feeding pipeline 226. After this, the second air supply port 224 supplies nitrogen into the material delivery tank 220, stopping when the second pressure sensor 225 detects that the pressure in the material delivery tank 220 has reached the set value. Then, the ninth pneumatic valve 2261 opens, and the material in the material delivery pipe is transported to the feeding device through the feeding pipeline 226. When the second weight sensor 221 detects that the weight decrease in the material delivery tank 220 has reached the set amount, feeding ends, and all pneumatic valves close.

[0075] In summary, the feeding device 200 provided in this embodiment achieves full-process isolation and protection during the feeding, delivery, and dispensing stages, preventing materials from being exposed to the environment and becoming contaminated, thus preventing material failure. It also avoids human contact with the materials, providing higher safety.

Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
