Description

Technical Field

[0001] This disclosure relates to the field of feeding technology, and more specifically, to a feeding device and a feeding system. Background Technology

[0002] The mixing and feeding process is an indispensable and important step in the manufacturing of battery electrodes, and it is also the first step in the manufacturing of battery cells.

[0003] Typically, during the mixing and feeding process, a crane is used to move the raw materials above the feeding port. Then, the ton bags are manually unpacked and placed over the feeding port, allowing the material in the ton bags to fall automatically into the discharge port. However, the current feeding process has poor sealing and dust collection, causing battery materials to easily leak from the hopper after being bagged and falling, resulting in a large amount of dust and reducing the overall material conveying efficiency.

[0004] Existing technologies typically utilize dust collectors for dust removal. However, excessive waste collected by dust collectors leads to a significant waste of raw materials. Furthermore, overloading dust collectors can cause rapid damage to filter elements, resulting in dust ejection and even dust explosions.

[0005] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0006] The purpose of this disclosure is to provide a feeding device and a feeding system.

[0007] According to one aspect of this disclosure, a feeding device is provided, the feeding device comprising:

[0008] The hopper includes a feeding port and a discharging port;

[0009] A feeding pipeline is provided with a first interface, a second interface and a third interface arranged in sequence on the feeding pipeline, the third interface being located at the feeding port end of the feeding pipeline; the discharge port is connected to the third interface;

[0010] A recycling pipeline, wherein the inlet of the recycling pipeline is located at the feeding port of the hopper, and the outlet of the recycling pipeline is connected to the second interface;

[0011] A blower, the outlet of which is connected to the first interface, is configured to deliver air into the feeding pipeline through the first interface.

[0012] In one exemplary embodiment of this disclosure, the air inlet of the recovery pipeline surrounds the feed inlet of the hopper.

[0013] In one exemplary embodiment of this disclosure, the feeding device further includes:

[0014] A flow guide is provided on the hopper, with its inlet facing the feeding port of the hopper and its outlet connected to the inlet of the recovery pipeline.

[0015] In one exemplary embodiment of this disclosure, the air inlet of the guide member surrounds the feeding port of the hopper.

[0016] In one exemplary embodiment of this disclosure, the feeding device further includes:

[0017] A recovery valve is provided between the outlet of the recovery pipeline and the second interface.

[0018] In one exemplary embodiment of this disclosure, the feeding device further includes:

[0019] A discharge valve is provided between the discharge port of the hopper and the third interface of the feeding pipeline.

[0020] In one exemplary embodiment of this disclosure, the feeding device further includes:

[0021] A pipeline valve is provided on the feed port of the feed pipeline, and the pipeline valve is configured to shut off or open the feed pipeline.

[0022] In one exemplary embodiment of this disclosure, the blower is a Roots blower, and a negative pressure is formed in the recovery pipeline.

[0023] In one exemplary embodiment of this disclosure, the feeding device further includes:

[0024] An air filter is provided at the air inlet of the fan.

[0025] According to another aspect of this disclosure, a feeding system is provided, which includes the feeding device described above.

[0026] The feeding equipment disclosed herein uses a fan to create a feeding power source in the feeding pipeline, enabling the material falling from the hopper outlet into the feeding pipeline to be transported to the mixing tank by air pressure. Due to the high air pressure in the feeding pipeline, the recovery pipeline is under negative pressure, allowing the material dust at the feeding port to be sucked into the feeding pipeline, thus reusing the material dust at the feeding port, avoiding excessive waste of raw materials, and reducing production costs. In other words, compared to existing technologies that typically use dust collectors for dust removal, the feeding equipment disclosed herein does not require a dust collector, thereby avoiding the risk of rapid filter damage, dust emission, or even dust explosion accidents caused by overloading the dust collector, further reducing production costs and improving production safety.

[0027] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and are not intended to limit this disclosure. Attached Figure Description

[0038] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore their detailed description will be omitted.

[0039] Although relative terms such as "up" and "down" are used in this specification to describe the relative relationship of one component of an icon to another, these terms are used only for convenience, such as according to the orientation of the examples shown in the accompanying drawings. It is understood that if the device of the icon is flipped upside down, the component described as "up" will become the component described as "down." When a structure is "up" of another structure, it may mean that the structure is integrally formed on the other structure, or that the structure is "directly" mounted on the other structure, or that the structure is "indirectly" mounted on the other structure through another structure.

[0040] The terms “a,” “one,” “the,” “the,” and “at least one” are used to indicate the presence of one or more elements / components / etc.; the terms “including” and “having” are used to indicate an open-ended inclusion and to mean that there may be other elements / components / etc. in addition to the listed elements / components / etc.; the terms “first,” “second,” and “third,” etc., are used only as markers and are not a limitation on the number of objects.

[0041] In related technologies, to address the large amount of dust generated at the feeding port during unpacking and feeding, a dust collector system is used to collect and dispose of the material dust during the feeding process. However, excessive waste collected by the dust collector results in a significant waste of raw materials. Furthermore, overloading the dust collector can cause rapid damage to the filter element, leading to dust emission and even dust explosions.

[0042] To address the aforementioned technical problems, this disclosure provides a feeding device, such as... Figure 1 and Figure 2As shown, the feeding equipment includes: a hopper 10, a feeding pipe 20, a recovery pipe 30, and a blower 41. The hopper 10 includes a feeding port 110 and a discharging port 120. The feeding pipe 20 is provided with a first interface 210, a second interface 220, and a third interface 230 arranged in sequence. The third interface 230 is located at the end near the feeding port 240 on the feeding pipe 20. The discharging port 120 is connected to the third interface 230. The inlet of the recovery pipe 30 is located at the feeding port 110 of the hopper 10, and the outlet of the recovery pipe 30 is connected to the second interface 220. The air outlet of the blower 41 is connected to the first interface 210, and the blower 41 is configured to supply air into the feeding pipe 20 through the first interface 210.

[0043] The feeding equipment provided in this disclosure forms a feeding power source in the feeding pipeline 20 through the blower 41, which can transport the material falling from the discharge port 120 of the hopper 10 into the feeding pipeline 20 to the mixing tank by air pressure. Due to the large air pressure in the feeding pipeline 20, the recovery pipeline 30 is in a negative pressure state. Through the recovery pipeline 30, the material dust at the feeding port 110 can be sucked into the feeding pipeline 20, and the recovered material is transported to the mixing tank by air pressure through the feeding pipeline 20. This allows the material dust at the feeding port 110 to be reused, avoiding excessive waste of raw materials and reducing production costs. In other words, the feeding equipment provided in this disclosure does not require a dust collector, thereby avoiding the situation where the dust collector is overloaded and the filter element is quickly damaged, dust is sprayed out, or even a dust explosion accident occurs. This can further reduce production costs and improve production safety.

[0044] The feeding equipment provided in this disclosure will now be described in detail.

[0045] In one embodiment, such as Figure 1 and Figure 2 As shown, the feeding device may include a support 50, a hopper 10, a feeding pipe 20, a recovery pipe 30, and a blower 41 which can be connected and assembled on the support 50.

[0046] The bracket 50 can be a frame structure, forming multiple installation spaces for mounting various components. The frame structure can be divided into upper and lower layers to accommodate the corresponding components. For example... Figure 1 The frame structure is also equipped with a material dropping platform, which is set opposite to the feeding port 110. The ton bag is placed on the material dropping platform for unpacking and unloading.

[0047] The support frame 50 adopts a frame structure, which can realize modularity, occupy less space, facilitate the handling and installation of the support frame 50, and can also adapt to accessories such as hoppers 10 of different sizes, thereby improving the economy of the feeding equipment.

[0048] The hopper 10 is mounted on the bracket 50. The hopper 10 can be funnel-shaped, which is larger at the top and smaller at the bottom, so that the material can fall to the discharge port 120 side under the action of gravity. The opening of the feeding port 110 can be set to be larger, which is conducive to feeding and avoids the material from spilling out.

[0049] During feeding, the ton bag is placed above the feeding port 110 by a manual operator, who then manually unpacks the bag, allowing the material inside to fall automatically to the discharge port. Due to the negative pressure created at the feeding port 110 of the hopper 10 by the blower 41, the floating material at the feeding port 110 is drawn into the hopper 10 by the material's own gravity and the negative pressure generated by the blower 41. Then, using the power generated by the blower 41, the powder falling from the hopper 10 to the feeding pipe 20 is transported to the mixing tank for batching. Of course, the handling and unpacking process of the ton bags can be fully automated, eliminating the need for manual handling and unpacking to improve production efficiency; this disclosure does not impose any limitations on this process.

[0050] The support frame 50 may be equipped with a lifting component, which can raise and lower the hopper 10 to adjust its height on the support frame 50, thereby adjusting the height of the feeding port 110 and preventing excessive floating material from the feeding port 110. The lifting component may include a cylinder, which is used to adjust the height of the hopper 10.

[0051] An observation port and / or a discharge port may be provided at the bottom of the hopper 10. The observation port allows for observation of the material falling into the hopper 10, preventing excessive material from causing blockage. When blockage occurs in the hopper 10 or when it is necessary to discharge the material from the hopper 10, the material can be discharged through the discharge port.

[0052] In one embodiment, such as Figure 1 As shown, the feeding device also includes a discharge valve 60, which is located between the discharge port 120 of the hopper 10 and the second interface 220 of the feeding pipeline 20. The discharge valve 60 can be used to open or close the flow of material from the hopper 10 into the feeding pipeline 20; by adjusting the opening of the discharge valve 60, the amount of material flowing into the feeding pipeline 20 can be adjusted.

[0053] Among them, the material discharge valve 60 can be an electrically controlled valve, and its opening degree can be adjusted through remote control to improve the automation level and visual monitoring of the equipment, so that the feeding equipment can accurately deliver materials to the target equipment.

[0054] Among them, the electrically controlled valve can be connected to a motor and a controller. The controller receives terminal commands to control the motor, and the opening degree of the electrically controlled valve is adjusted by the motor.

[0055] The discharge valve 60 can be installed in the lower space of the bracket 50, positioned above and below the hopper 10. The discharge valve 60 is connected to the discharge port 120 of the hopper 10, thus indirectly fixing it to the bracket 50. The discharge valve 60 and the discharge port 120 of the hopper 10 can be connected by a flange.

[0056] In one embodiment, such as Figure 1 As shown, the material discharge valve 60 and the material feeding pipeline 20 can also be connected by a flange.

[0057] A connecting pipe can be provided between the discharge valve 60 and the feeding pipe 20. One end of the connecting pipe is connected to the outlet of the discharge valve 60, and the other end is connected to the third interface 230 on the feeding pipe 20.

[0058] One end of the connecting pipe can be connected to the outlet of the discharge valve 60 via a flange, and the other end of the connecting pipe can be connected to the third interface 230 on the feeding pipe 20 via welding. Of course, the interfaces can be connected together by welding, bonding, threaded connection, riveting, snap-fit, etc., and this disclosure does not impose any restrictions on this.

[0059] In one embodiment, the blower 41 is a Roots blower 41. The air volume of the Roots blower 41 is less affected by pressure changes, and its rotational speed is proportional to the air volume, thus providing a stable air volume output. It is essentially a constant-volume blower 41, which allows for precise control of the feeding amount. At the same time, the gap between the rotor and the housing of the Roots blower 41 allows the airflow to contain dust, making it particularly suitable for conveying anode and cathode powder materials. In addition, the Roots blower 41 is small in size, operates stably and reliably, is easy to maintain, has a long service life, and generates relatively little noise and vibration during operation, resulting in a smaller impact on the environment.

[0060] It is understood that the fan 41 can also be an axial flow fan, a centrifugal fan, a rotary fan, a crossflow fan, etc., and this disclosure does not impose any restrictions on it.

[0061] The blower 41 can create negative pressure in the recovery pipeline 30.

[0062] Among them, such as Figure 1 As shown, the feeding device also includes an air filter 42, which is located at the air inlet of the fan 41. Since the fan 41 is in an environment with a lot of dust, the air filter 42 can filter the air entering the fan 41, preventing dust from entering the fan 41 and affecting its lifespan.

[0063] In one embodiment, such as Figure 2As shown, the feeding device also includes a recovery valve 70, which is located between the outlet of the recovery pipeline 30 and the second interface 220. By setting the recovery valve 70, the recovery pipeline 30 can be opened and closed, and the negative pressure in the recovery pipeline 30 can be adjusted. This allows for adjustment of the negative pressure in the recovery pipeline 30 based on the dust concentration at the feeding port 110, thereby adjusting the negative pressure at the inlet of the recovery pipeline 30.

[0064] The recovery valve 70 can be a manual valve or an electric valve, and this disclosure does not impose any restrictions on it.

[0065] The recovery valve 70 is located near the feeding pipeline 20, which facilitates operation when using a manual valve.

[0066] One end of the recovery valve 70 is inserted into the recovery pipeline 30, and the other end of the recovery valve 70 is fixedly connected to the feeding pipeline 20.

[0067] A connecting pipe can be provided between the recovery valve 70 and the feeding pipe 20. One end of the connecting pipe is connected to the outlet of the recovery valve 70, and the other end is connected to the second interface 220 on the feeding pipe 20.

[0068] The outlet of the recovery valve 70 at one end of the connecting pipeline can be connected by a plug-in connection, and the other end of the connecting pipeline can be connected to the second interface 220 on the feeding pipeline 20 by welding. Of course, the interfaces can be connected together by welding, bonding, threaded connection, riveting, snap-fit, etc., and this disclosure does not limit this.

[0069] It is understood that the recovery pipeline 30 is connected to the feeding pipeline 20 through the second interface 220, and the angle between the part of the recovery pipeline 30 connected to the second interface 220 and the side of the recovery pipeline 30 near the fan 41 is a right angle or an acute angle; or the angle between the central axis of the second interface 220 and the central axis of the recovery pipeline 30 near the fan 41 at the location where the second interface 220 is set is a right angle or an acute angle, so that after the fan 41 sends air into the feeding pipeline 20, a negative pressure can be formed at the recovery pipeline 30 or the second interface 220, so that the recovery pipeline 30 can use the negative pressure to recover dust through the air inlet.

[0070] In one embodiment, the feeding device further includes a pipeline valve (not shown in the figure), which is disposed on the feed port 240 of the feeding pipeline 20 and is configured to close or open the outlet of the feeding pipeline 20. By providing the pipeline valve, the outlet of the feeding device can be closed or opened with other cooperating devices.

[0071] The pipeline valves can be manual or electric, and this disclosure does not impose any restrictions on them.

[0072] The pipeline valves are located near the feed pipeline 20 to facilitate operation when using manual valves.

[0073] In one embodiment, the air inlet of the recovery pipe 30 surrounds the feeding port 110 of the hopper 10. This allows the air inlet to perform dust suction in the circumference of the feeding port 110, thereby improving the dust suction effect.

[0074] The air inlet of the recovery pipe 30 can be annular, surrounding the feeding port 110 of the hopper 10. By making the air inlet of the recovery pipe 30 annular and surrounding the feeding port 110 of the hopper 10, the air inlet can perform dust suction in the circumference of the feeding port 110, thereby improving the dust suction effect. Of course, the air inlet of the recovery pipe 30 can also be quasi-annular, for example, in a C-shape with a notch and break.

[0075] like Figure 1 As shown, the feeding device also includes a guide member 33, which is disposed on the hopper 10. The inlet of the guide member 33 is opposite to the feeding port 110 of the hopper 10, and the outlet of the guide member 33 is connected to the inlet of the recovery pipeline 30. By setting the guide member 33, a suction nozzle structure of the recovery pipeline 30 is formed, which can better adapt to the size and shape of the feeding port 110.

[0076] Among them, such as Figures 4-7 As shown, the air inlet 330 of the guide component 33 surrounds the feeding port 110 of the hopper 10, so that the air inlet 300 can perform dust suction in the circumference of the feeding port 110, thereby improving the dust suction effect.

[0077] In one embodiment, such as Figure 4 and Figure 5 As shown, the guide member 33 can be annular, and multiple air inlets 330 are formed around the feeding port 110 on the inner ring of the guide member 33. The multiple air inlets 300 perform negative pressure dust suction around the feeding port 110, thereby improving the dust suction effect.

[0078] In one embodiment, such as Figure 6 and Figure 7 As shown, the guide member 33 can be annular and has an annular air inlet 330, which surrounds the feeding port 110 of the hopper 10. This allows the guide member 33 to perform dust suction in the circumference of the feeding port 110, thereby improving the dust suction effect.

[0079] Understandably, the air inlet of the air guide 33 can also be ring-shaped, for example, in the form of a C-shape with a notch and break.

[0080] In one embodiment, such as Figure 1 and Figure 2As shown, the feeding equipment includes a recovery pipeline 30. The recovery pipeline 30 enables the recovery of floating materials, reducing equipment upgrade and modification costs.

[0081] In one embodiment, such as Figure 3 As shown, the feeding equipment includes two recovery pipelines 30, namely the first recovery pipeline 31 and the second recovery pipeline 32. By setting up the first recovery pipeline 31 and the second recovery pipeline 32, floating materials can be recovered simultaneously, thereby improving the dust recovery capacity.

[0082] The opening and closing of the first recovery pipeline 31 and the second recovery pipeline 32 can be controlled by setting a recovery valve 70, such as... Figure 3 As shown, a recovery valve 70 is installed on the second recovery pipeline 32 to control the opening and closing of the second recovery pipeline 32; of course, a recovery valve 70 may also be installed between the first recovery pipeline 31 and the feeding pipeline 20, and this disclosure does not limit this.

[0083] In one embodiment, the feeding pipeline 20 may be a single complete pipeline or may be formed by connecting multiple sub-pipelines, and the interfaces may be distributed on different sub-pipelines. This disclosure does not impose any restrictions on this.

[0084] When the feeding pipeline 20 is formed by connecting multiple sub-pipes, the multiple sub-pipes can be fixed and connected by welding, threaded connection, bonding and other methods, which facilitates the handling and installation of the feeding pipeline 20, facilitates the connection of different other components, has low cost and is beneficial for later maintenance.

[0085] Embodiments of this disclosure also provide a feeding system, which includes the feeding equipment provided in the above embodiments. The feeding system may further include a mixing station, through which the feeding system feeds the material to the mixing station. The mixing station mixes the incoming material using a mixing tank to deliver the uniformly mixed raw materials to subsequent process equipment, such as mixing raw materials for battery electrode manufacturing.

[0086] Other embodiments of this disclosure will readily occur to those skilled in the art upon consideration of the specification and practice of the invention disclosed herein. This application is intended to cover any variations, uses, or adaptations of this disclosure that follow the general principles of this disclosure and include common knowledge or customary techniques in the art not disclosed herein.

[0087] It should be understood that this disclosure is not limited to the precise structures described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope. The scope of this disclosure is limited only by the appended claims.
