Description

Technical Field

[0001] This utility model relates to the field of material feeding technology, and in particular to a powder feeding auxiliary device. Background Technology

[0002] With the rise of new energy technologies, a large amount of precious metals, such as Ni, Co, and Mn, are used in new energy vehicle batteries. These precious metals mostly exist in the form of powder. During the recycling of used batteries, a certain amount of precious metals cannot be recycled. Therefore, it is necessary to add raw materials containing precious metals to compensate for this and ensure that the battery powder meets the prescribed qualification standards.

[0003] In the production process, workers use cranes or forklifts to lift packages containing raw materials onto the raw material tanks, then unpack them and feed the powder into the slurry tank. After being made into a slurry, it is transported to the subsequent leaching and extraction stage. However, the current unpacking and feeding method easily generates a lot of dust, which not only causes a great loss of precious metal raw materials, but also damages the cleanliness of the factory area and poses a threat to the health of workshop workers. Utility Model Content

[0004] In view of this, the purpose of this utility model is to overcome the shortcomings in related technologies, and this utility model provides a powder feeding auxiliary device.

[0005] This utility model provides the following technical solution: A powder feeding auxiliary device includes a feeding pipe, a feeding hopper, and a packing cone.

[0006] The feeding pipe is installed above the pulping tank of the production equipment, and the lower opening of the feeding pipe is connected to the interior of the pulping tank. The lower end of the feeding hopper is connected to the upper opening of the feeding pipe. The inner diameter of the feeding hopper is larger than the diameter of the feeding pipe. The upper opening of the feeding hopper is a baffle, which bends and narrows towards the axis of the feeding pipe. The feeding hopper is used to place ton bags. The bag-breaking cone is installed inside the feeding pipe and is used to puncture the ton bags placed in the feeding hopper.

[0007] As a further improvement to the above technical solution, the diameter of the material stop is L1, the diameter of the ton bag in the hoisting state is L2, and the diameter of the ton bag when placed in the feeding hopper is L3. L1, L2, and L3 satisfy: L2≤L1<L3.

[0008] As a further improvement to the above technical solution, the material stop is connected to an inverted conical feed hopper.

[0009] As a further improvement to the above technical solution, the feeding pipe is inserted into the pulping tank, and the lower opening of the feeding pipe extends below the surface of the pulp liquid in the pulping tank.

[0010] As a further improvement to the above technical solution, the powder feeding auxiliary device also includes a cover, which is installed outside the feeding pipe and the feeding hopper.

[0011] As a further improvement to the above technical solution, the enclosure is connected to a suction device via a suction pipe.

[0012] As a further improvement to the above technical solution, at least two suction pipes are provided.

[0013] As a further improvement to the above technical solution, the suction pipe is inserted into the hood away from the opening of the suction device and connected to a funnel-shaped gas collection hood, the opening of which faces the upper opening of the feed hopper.

[0014] As a further improvement to the above technical solution, the suction device is a bag filter, and the suction pipe is connected to the suction port of the bag filter, away from the opening of the hood.

[0015] As a further improvement to the above technical solution, the pack-breaking cone is a cross-shaped cutter.

[0016] Compared with related technologies, the beneficial effects of this utility model are: The powder feeding auxiliary device provided by this utility model, in actual use, firstly, uses a transport vehicle to hoist the ton bag containing powder. The transport vehicle needs to hoist the ton bag to a position directly above the material stop at the top of the feeding hopper. After ensuring accurate positioning, the ton bag in the hoisting state slowly passes through the material stop and smoothly enters the feeding hopper.

[0017] The feed hopper is connected to the feeding pipe at the bottom, and a puncturing cone is installed inside the feeding pipe. When the ton bag enters the feed hopper, the puncturing cone will puncture the ton bag as it continues to fall. Once the ton bag is punctured, the powder inside will fall naturally and flow smoothly into the pulping tank of the production equipment through the feeding pipe, thus participating in the subsequent mixing production process.

[0018] Furthermore, due to the blocking effect of the deburring cone, the ton bags do not fall directly into the feeding pipe after entering the feeding hopper, but are instead placed in a stacked state inside the feeding hopper. At this time, the outer diameter of the ton bags increases in the stacked state, and they gradually move closer to the edge of the baffle.

[0019] This structural design offers numerous benefits. The side wall of the feed hopper near the material inlet works in conjunction with the ton bag to form an effective barrier. During the ton bag feeding process, dust is inevitably generated, and this barrier, composed of the side wall and the ton bag, effectively blocks this dust, significantly reducing powder spillage. This not only effectively reduces powder pollution to the production environment, creating a relatively clean and healthy working environment for workers and minimizing the potential health impacts of powder; but also, for some precious metal powders, reduced spillage means reduced waste, improved raw material utilization, and lower production costs.

[0020] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, preferred embodiments are described below in detail with reference to the accompanying drawings. Attached Figure Description

[0029] like Figure 1 As shown, an embodiment of this utility model provides a powder feeding auxiliary device, including a feeding pipe 100, a feeding hopper 300, and a packing cone 110.

[0030] The feeding pipe 100 is vertically installed above the pulping tank 210 of the production equipment 200, and the lower opening of the feeding pipe 100 is connected to the interior of the pulping tank 210; the lower end of the feeding hopper 300 is connected to the upper opening of the feeding pipe 100, the inner diameter of the feeding hopper 300 is larger than the diameter of the feeding pipe 100, and the upper opening of the feeding hopper 300 is a baffle 310, which bends and narrows towards the axis of the feeding pipe 100. The feeding hopper 300 is used to place ton bags; the bag-piercing cone 110 is installed inside the feeding pipe 100 and is used to pierce the ton bags placed in the feeding hopper 300.

[0031] In actual use, the powder feeding auxiliary device provided in this embodiment first uses a transport vehicle to hoist the ton bag containing the powder. The transport vehicle needs to hoist the ton bag to a position directly above the material stop 310 at the top of the feeding hopper 300. After ensuring that the position is accurate, the ton bag in the hoisting state slowly passes through the material stop 310 and smoothly enters the feeding hopper 300.

[0032] The feed hopper 300 is connected to the feeding pipe 100 below, and a puncturing cone 110 is installed inside the feeding pipe 100. When the ton bag enters the feed hopper 300, the puncturing cone 110 will puncture the ton bag as it continues to fall. Once the ton bag is punctured, the powder inside will fall naturally and smoothly enter the pulping tank 210 of the production equipment 200 through the feeding pipe 100, and then participate in the subsequent mixing production process.

[0033] Furthermore, due to the blocking effect of the bag-breaking cone 110, the ton bags will not fall directly into the feeding pipe 100 after entering the feeding hopper 300, but will be placed in a stacked state inside the feeding hopper 300. At this time, the outer diameter of the ton bags increases in the stacked state, and they will gradually move closer to the edge of the baffle 310.

[0034] This structural design offers numerous benefits. The side wall of the feed hopper 300 near the baffle 310 works in conjunction with the ton bag to form an effective barrier. During the ton bag feeding process, dust is inevitably generated, and this barrier, composed of the side wall and the ton bag, effectively blocks this dust, significantly reducing powder spillage. This not only effectively reduces powder pollution to the production environment, creating a relatively clean and healthy working environment for workers and minimizing the potential health impacts of powder; but also, for some precious metal powders, reduced spillage means reduced waste, improved raw material utilization, and lower production costs.

[0035] In some specific embodiments, the diameter of the material stop 310 is L1, the diameter of the ton bag in the hoisting state is L2, and the diameter of the ton bag when placed in the feeding hopper 300 is L3. L1, L2, and L3 satisfy: L2≤L1<L3. Specifically, limiting the size of the material stop 310 according to the above requirements has many important functions.

[0036] First, when L2≤L1, it ensures that the ton bag in the hoisting state can smoothly pass through the material stop 310 during the hoisting process and accurately enter the feeding hopper 300. This design ensures the smooth progress of the preparatory work before feeding and avoids the situation where the ton bag cannot enter the feeding hopper 300 due to the material stop 310 being too small, thus affecting the entire feeding process.

[0037] Secondly, after the ton bag enters the feeding hopper 300, due to the internal space of the feeding hopper 300 and the structure such as the rupture cone 110, the ton bag will transform into a stacked state. At this time, its diameter becomes L3, and L1 < L3. This dimensional relationship allows the edge of the baffle 310 to engage with the side wall of the ton bag in the stacked state. This engagement creates a relatively sealed environment. During the ton bag feeding process, when powder falls from the punctured ton bag, it further reduces the probability of powder splashing out from the gap between the baffle 310 and the ton bag. This effectively reduces powder spillage, which not only helps maintain a clean production environment and reduces powder pollution to the surrounding air, but also reduces powder waste. Especially for some valuable powders, it improves the utilization rate of raw materials, reduces production costs, and also protects the health of workers, preventing them from being harmed by inhaling excessive powder.

[0038] In some specific embodiments, the baffle 310 is connected to an inverted conical feed hopper 400; this inverted conical feed hopper 400 has a unique and practical function. During the feeding operation, when workers hoist ton bags containing powder into the feed hopper 300, the ton bags, due to their large size and soft texture, are prone to shaking and shifting during hoisting, making it difficult to accurately pass the ton bags through the baffle 310 and into the feed hopper 300. However, the feed hopper 400's shape, wider at the top and narrower at the bottom, allows the ton bags to naturally converge towards the center of the baffle 310 along its conical sidewall as they approach it, enabling them to smoothly pass through the baffle 310 and enter the feed hopper 300.

[0039] By designing an inverted cone-shaped feed hopper 400, the difficulty of lifting ton bags into the feed hopper 300 is greatly reduced. Workers do not need to spend excessive time and effort adjusting the position of the ton bags; they only need to roughly lift the ton bags above the feed hopper 400, and guided by the feed hopper 400, the ton bags can easily enter the feed hopper 300. This not only reduces the labor intensity of workers but also avoids prolonged feeding time due to operational difficulties, thereby significantly improving the efficiency of the entire production process and enabling production to proceed more smoothly and quickly.

[0040] In some specific embodiments, the feeding pipe 100 is installed inside the pulping tank 210, and the lower opening of the feeding pipe 100 extends below the slurry liquid surface 211 inside the pulping tank 210. In actual production, when the powder in the ton bag is conveyed to the pulping tank 210 through the feeding hopper 300 and the feeding pipe 100, since the lower opening of the feeding pipe 100 is below the slurry liquid surface 211, the powder entering the feeding pipe 100 from the ton bag can be directly submerged into the slurry in the pulping tank 210.

[0041] This design has several important advantages. Firstly, the powder enters the slurry directly, avoiding the situation where the powder disperses in the air before falling into the slurry after entering the pulping tank 210. If the powder disperses in the air, it will not only generate a large amount of dust, which will permeate the production environment, seriously polluting air quality and affecting workers' health, potentially leading to respiratory diseases, but the dust will also adhere to the surface of the production equipment 200, increasing the difficulty of cleaning and maintenance costs, and affecting the normal operation and lifespan of the equipment. Secondly, the direct entry of the powder into the slurry allows for faster and more thorough mixing, improving pulping efficiency and quality, ensuring that the produced slurry has stable and uniform properties, and meeting the requirements of subsequent production processes.

[0042] like Figure 2As shown, in some specific embodiments, the powder feeding auxiliary device further includes a cover 500, which covers the feeding pipe 100 and the feeding hopper 300. The cover 500 has a sliding door on its side for transport equipment to pass through. During the feeding operation, due to factors such as punctures in the ton bags and powder flow, some powder will inevitably splash out from inside the feeding hopper 300 or from the damaged parts of the ton bags. At this time, the cover 500 can strictly limit and control the powder splashed out from the feeding hopper 300 and the ton bags, confining this scattered powder within a relatively fixed and small space. In this way, the splashed powder will not spread unchecked throughout the production environment, thereby greatly reducing powder pollution to the production environment. The air quality in the production workshop can be better maintained, avoiding problems such as reduced visibility and dust accumulation on equipment surfaces caused by powder dispersion. This creates a relatively clean and safe working environment for workers, which is conducive to protecting their health and reducing the risk of respiratory diseases and other health problems caused by excessive powder inhalation.

[0043] Meanwhile, since the powder is contained within the enclosure 500, subsequent cleaning becomes easier and more efficient. Workers no longer need to perform comprehensive dust cleaning across the entire large production area; they only need to clean the relatively concentrated area inside the enclosure 500. This significantly saves cleaning time and labor costs, improves production efficiency, and reduces the company's operating costs.

[0044] In some specific embodiments, the enclosure 500 is connected to the suction device 520 through the suction pipe 510, which is used to directly perform negative pressure suction of the powder dust that appears in the enclosure 500, so as to facilitate the suction and recovery of the overflowing powder.

[0045] In some specific embodiments, at least two suction pipes 510 are provided to improve the suction effect of powder in the enclosure 500.

[0046] In some specific embodiments, the suction pipe 510 passes through the hood 500 away from the opening of the suction device 520 and is connected to a funnel-shaped gas collecting hood 511, the opening of which faces the upper opening of the feed hopper 300. From the perspective of the suction surface, the funnel-shaped gas collecting hood 511 greatly improves the suction surface of the suction pipe 510 within the hood 500. Because its opening gradually widens in a funnel shape, it can cover a larger space, and compared to situations without a gas collecting hood 511 or with a small opening, it can collect more powder raised from the feed hopper 300 and its surrounding area. This means that with the same time and suction power, more dust can be sucked away, improving dust removal efficiency.

[0047] In terms of targeted suction, the opening of the dust collection hood 511 faces the upper opening of the feed hopper 300. This targeted design facilitates targeted suction of the area near the feed hopper 300, where dust from powder is most concentrated. During the feeding process, the powder falling from the ton bag into the feed hopper 300 generates a significant impact force, and at the end of each ton bag's discharge phase, when it is shrunken, a large amount of powder is thrown up. The area near the upper opening of the feed hopper 300 is the main source of dust. By targeting this area, the dust collection hood 511 can quickly suck the just-thrown powder into the suction pipe 510, preventing it from further spreading to other parts of the hood 500 or even the production environment.

[0048] In some specific embodiments, the suction device 520 is a bag filter. As a mature and widely used dust removal device, the bag filter has many significant advantages. It filters dust-laden gas through filter bags, effectively separating dust particles from the gas. It features high dust removal efficiency, large air volume handling capacity, and stable operation, making it very suitable for handling the large amount of dust generated during powder feeding.

[0049] The suction pipe 510, located away from the opening of the hood 500, is tightly and reliably connected to the suction port of the bag filter. During the feeding operation, a large amount of dust is generated inside the hood 500 due to the flow and impact of the powder. At this time, the bag filter starts working, and its powerful suction force causes the air inside the hood 500 to flow in a directional manner. The dust is drawn into the bag filter along with the air through the suction pipe 510.

[0050] Using baghouse dust collectors for gas extraction offers significant convenience and practicality. When dust-laden gas enters the baghouse, the dust is intercepted by the filter bags and adheres to their surface, while the purified gas is discharged through the filter bags. As the filtration process continues, the dust on the filter bag surface gradually increases. When it reaches a certain thickness, the baghouse dust collector uses a cleaning device (such as pulse jet cleaning) to shake off the dust and collect it in the ash hopper below. The collected dust has a composition essentially the same as the original feed material, is not heavily contaminated by other pollutants, and is of relatively high quality.

[0051] Because the powder is directly collected into the ash hopper in the baghouse dust collector, subsequent processing is very convenient. Enterprises can directly reuse this collected powder in secondary production according to their production needs, eliminating the need for complex processing procedures. This reduces raw material waste, lowers production costs, and improves resource utilization, aligning with the concept of sustainable development. Simultaneously, it avoids the pollution caused by indiscriminate discharge of powder, achieving green and environmentally friendly operation of the production process.

[0052] In some specific embodiments, the puncture cone 110 is a cross-shaped cutter. In actual production, ton bags are usually made of materials such as polypropylene with certain strength and toughness, and their surface is relatively thick and has a certain puncture resistance. Ordinary puncture tools may have difficulty quickly and effectively puncturing ton bags, or they may slip or fail to penetrate deeply during the puncture process, thus hindering the feeding process. The cross-shaped cutter has a unique shape advantage; its blades are distributed in a cross shape, forming multiple sharp puncture points.

[0053] Once the ton bag enters the feed hopper 300, it comes into contact with the cross-shaped cutter under the force of gravity. At this point, the multiple puncture points of the cross-shaped cutter can simultaneously apply force to the surface of the ton bag, increasing the success rate and efficiency of puncture. Compared to tools with a single puncture point, the cross-shaped cutter can more easily break through the surface defenses of the ton bag and quickly penetrate its interior. Moreover, due to its intersecting structural design, after puncturing the ton bag, it can also create a certain tearing effect, further enlarging the puncture opening and ensuring that the powder can flow out of the ton bag more smoothly.

[0054] By employing a cross-shaped cutter as the puncture cone 110, the ton bags entering the feed hopper 300 can be reliably punctured. This design effectively avoids problems such as feeding interruptions and powder blockages caused by difficulties in puncturing the ton bags, greatly improving the stability and smoothness of the feeding process and providing strong support for the smooth operation of the entire powder production process.
