Description

Technical Field

[0001] This utility model generally relates to the field of material storage and transportation technology. More specifically, this utility model relates to a material receiving device and a material storage and transportation system. Background Technology

[0002] In production processes such as lithium battery manufacturing, powdered materials like graphite in negative electrode materials have a large specific surface area, resulting in highly active atoms on the material surface that readily react with oxygen molecules in the air. During material storage, friction and impacts caused by bumps and handling during loading and unloading cause these powders to accumulate static electricity. When the static energy reaches a certain level, and there is a lack of sealing, a sudden release of an electric spark can ignite the material, leading to spontaneous combustion or even an explosion. Furthermore, powdered materials easily disperse during storage and transportation, forming a mixture suspended in the air. If this mixture reaches an explosive concentration in a relatively enclosed space with poor sealing, even a tiny ignition source can trigger an explosion. Therefore, strengthening sealing and preventing leakage when storing powdered materials such as negative electrode materials is crucial for ensuring transportation safety. However, current material storage equipment on the market, limited by sealing structure design and manufacturing processes, has many defects in sealing performance, making it difficult to completely eliminate powder leakage, thus keeping the explosion risk high. How to improve the sealing performance of materials during storage by improving the sealing structure and optimizing the manufacturing process has become a technical challenge that urgently needs to be overcome.

[0003] In view of this, there is an urgent need to provide a material receiving device and a material storage and transportation system in order to improve the sealing effect during the material storage and transportation process. Utility Model Content

[0030] In view of this, the present utility model provides a receiving device and a material storage and transportation system, which, by setting a main material bin, a receiving component and a discharging component connecting the main material bin and the receiving component, and setting a clamping mechanism between the discharging component and the receiving container, can maintain the clamping and sealing of the receiving container during the receiving process, thereby improving the overall sealing effect.

[0031] The specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0032] See also Figures 1 to 3 , Figure 1 An exemplary front view of a receiving device according to some embodiments of the present invention is shown. Figure 2 An exemplary cross-sectional view of a material receiving device according to some embodiments of the present invention is shown. Figure 3 It shows Figure 2 A magnified view of part A in the diagram.

[0033] In this embodiment, the receiving device 100 includes a main hopper 10, a receiving assembly 20, and a discharging assembly 30. The main hopper 10 includes a storage chamber 110 for storing materials. The receiving assembly 20 includes a sealable receiving chamber 210 for holding a receiving container 90. The discharging assembly 30 includes a discharging pipe 31, one end of which communicates with the storage chamber 110 to receive materials, and the other end extends into the receiving chamber 210 to communicate with the receiving container 90. A clamping mechanism 40 is also provided on the discharging pipe 31, which clamps and seals the receiving container 90 relative to the discharging pipe 31.

[0034] Specifically, the main hopper 10 and the receiving assembly 20 are fixed relative to each other. The main hopper 10 has a generally cylindrical barrel body, the interior of which is defined as a storage chamber 110. The upper side of the main hopper 10 is connected to other material storage devices via pipes to receive materials to be stored. The materials to be stored are transported to the main hopper 10 via pipes by means of negative pressure conveying or the like. The receiving assembly 20 includes a generally rectangular frame body with a hollow interior. The upper side of the receiving assembly 20 frame body is fixedly connected to the barrel body of the main hopper 10, and a horizontal side of the receiving assembly 20 can be opened outwards to allow the receiving container 90 to enter the receiving chamber 210 of the receiving assembly 20 through the open side. Furthermore, a sealing door can be provided on the open side to seal the receiving chamber 210 during the receiving process, preventing the receiving container 90 from being contaminated by external gases and dust. The lower side of the main material bin 10 is connected to the discharge pipe 31 of the discharge assembly 30. The discharge pipe 31 is used to further connect to the receiving container 90, so that the material in the storage chamber 110 can be input into the receiving container 90 through the discharge pipe 31.

[0035] The receiving container 90 is a flexible storage container, such as a ton bag, used to hold and store powdered materials. Its opening is fixedly connected to the outlet of the discharge pipe 31 located in the receiving chamber 210 by means of a clamping mechanism 40, and is sealed relative to the receiving chamber 210 by means of the clamping mechanism 40. The clamping mechanism 40 includes an actuating component driven by a driving device such as a cylinder or air pump. The actuating component is an arc-shaped gripper or an arc-shaped elastic element, which can be displaced or deformed under the drive of the driving device to apply pressure toward the adjacent area of ​​the receiving container 90 and the discharge pipe 31, so that the two are fixed relative to each other and sealed together. Thus, during the receiving process, the inside of the receiving container 90 is connected to the storage chamber 110 through the discharge pipe 31 to receive materials, and at the same time, it is sealed relative to the receiving chamber 210 by means of the clamping mechanism 40 to prevent external oxidizing gases from entering the inside of the receiving container 90, and at the same time reduce the escape of negative electrode materials during the receiving process.

[0036] See also Figure 2 and Figure 3In this embodiment, the clamping mechanism 40 includes an airbag fixing member 42 and an airbag 41 disposed inside the airbag fixing member 42. The airbag 41 is configured to surround the outer periphery of the discharge tube 31. The clamping mechanism 40 is formed as a ring, and the airbag 41, which is also formed as a ring, is connected to an air pump. Under the action of the air pump, the airbag 41 can expand and contract around the outer periphery of the discharge tube 31. When the airbag 41 is not inflated, there is a gap between the radially inner side of the annular airbag 41 and the outer periphery of the discharge tube 31. This gap allows the opening of the receiving container 90 to be fitted onto the outer periphery of the discharge tube 31. When the airbag 41 is inflated, the radially inner side of the airbag 41 abuts against the portion of the opening of the receiving container 90 located outside the discharge tube 31, thereby uniformly fixing and sealing the opening of the receiving container 90 outward around the discharge tube 31. Therefore, by expanding and contracting the airbag 41, the sealing connection between the discharge pipe 31 and the receiving container 90 can be completed quickly. Due to the flexible nature of the expanded airbag 41, the airbag 41 can evenly conform to the opening shape of the receiving container 90 by deformation when it expands, which improves the sealing effect and reduces the probability of leakage caused by shape errors or wrinkles at the opening of the receiving container 90.

[0037] Those skilled in the art will understand that, in some embodiments not shown, the clamping mechanism includes a plurality of annular airbags arranged sequentially along the axial direction of the discharge tube 31 to further improve the sealing effect. Alternatively, in some other embodiments, the clamping mechanism includes a plurality of airbags arranged sequentially along the circumferential direction on the outside of the discharge tube to reduce the probability of poor sealing due to insufficient local deformation of the airbag after pressurization when using a single airbag.

[0038] See also 2 and Figure 5 , Figure 5 An exemplary perspective view of a receiving device according to some embodiments of the present invention is shown. In this embodiment, a vacuum pump 50 is also included, which is connected to the discharging assembly 30 to evacuate the receiving container 90. The vacuum pump 50 is driven by a motor or other drive device, and its vacuum inlet is connected to the side wall of the discharging pipe 31 via a pipe. Thus, when the vacuum pump 50 is started, it can provide negative pressure into the discharging pipe 31. During loading, after sealing the opening of the receiving container 90 to the discharging pipe 31, the vacuum pump 50 can be started to evacuate the receiving container 90, thereby removing existing gases such as oxygen from the receiving container 90 and preventing negative effects such as oxidation on the powder material during receiving and storage, thereby improving the storage effect of the powder material and reducing the rate of powder material deterioration.

[0039] See also Figure 2 and Figure 6 , Figure 6An exemplary perspective view of a receiving device according to some embodiments of the present invention is shown. In this embodiment, a protective gas assembly 60 is further included, which is connected to the discharging assembly 30 to inject protective gas into the receiving container 90. The protective gas assembly 60 includes a protective gas pipe for connecting to the discharging assembly 30 and a protective gas valve for controlling the opening and closing of the protective gas pipe. The protective gas pipe is connected to the side wall of the discharging pipe 31 to inject protective gas, such as nitrogen or an inert gas, into the receiving container 90. During the receiving process, the protective gas valve opens after the receiving container 90 is connected to the discharging pipe 31. If a vacuum pump 50 is provided, the protective gas valve opens after evacuating the receiving container 90, filling the receiving container 90 with protective gas, and closes after the protective gas is filled. This protective gas can form a "gas shield" to envelop the material, reducing the chance of powder particles coming into contact with gases such as oxygen during the receiving process and the subsequent storage stage. On the one hand, it reduces the rate of chemical changes such as slow oxidation of the powder material, and on the other hand, it reduces the probability of combustion caused by frictional static electricity generated during the receiving or transportation process, which may then occur with the participation of oxidizing gases, thereby improving the safety of production and storage.

[0040] See you again Figure 2 and Figure 3 In this embodiment, a pressure sensor 32 is also provided within the discharge assembly 30. The pressure sensor 32 includes a pressure detection module for detecting the air pressure within the discharge pipe 31. This allows for monitoring the air pressure status within the discharge pipe 31 during operational phases such as vacuuming, protective gas injection, or material collection, reducing the probability of leakage due to misoperation or unexpected pressure fluctuations. The pressure detection module can be electrically connected to the pressure sensor 32's own control module and / or alarm module to convert the detected values ​​into indication or alarm signals for the user. Alternatively, in some other embodiments, the pressure sensor 32 can be electrically connected to other independent control modules, alarm modules, actuators, and other devices to cooperate with other components in controlling the air pressure, further improving the sealing effect and safety during the material collection process.

[0041] See you again Figure 2 and Figure 6In this embodiment, a breather valve 70 is also included, which is connected to the discharge assembly 30. An activation valve 71 is also provided between the breather valve 70 and the discharge assembly 30, and the activation valve 71 is electrically connected to the pressure sensor 32. The breather valve 70 is connected to the discharge pipe 31 via a pipeline and the activation valve 71, and also to a gas source that can provide protective gas. During the material receiving process, the pneumatic valve and the breather valve 70 can switch on and off according to the pressure value detected by the pressure sensor 32, thereby controlling the air pressure in the receiving container 90 within a preset ideal range. The activation valve 71 is a pneumatic valve such as a butterfly valve, and both the breather valve 70 and the activation valve 71 are solenoid valves. When controlling the activation valve 71 and the breather valve 70, a single control signal drives a double-contact relay, simultaneously outputting two signals to the solenoid valves of the breather valve 70 and the activation valve 71, thereby simultaneously opening the pneumatic butterfly valve, establishing an air passage, and ensuring pressure balance within the receiving container 90.

[0042] See also Figure 2 and Figure 4 , Figure 4 It shows Figure 2 A partially enlarged schematic diagram of part B. In this embodiment, a sampling device 80 is also included, one side of which is connected to the feeding assembly 30, and the other side extends into the receiving chamber 210. The sampling device 80 is used to simultaneously sample the material during the feeding process, for quality inspection or other testing of the same batch of material without opening the package. One side of the sampling device 80 is connected to the feeding pipe 31 to intercept material during the receiving process, and the other side extends into the receiving chamber 210, allowing the operator to collect the sample while collecting the receiving container 90. Thus, the sampling device 80 can improve the consistency between the sampled material and the collected material.

[0043] Furthermore, the sampling device 80 also includes a sampling tube 81 and a sampling spoon 82. The sampling tube 81 is connected to the receiving assembly 20, and the sampling spoon 82 is disposed in the sampling tube 81. Specifically, the sampling tube 81 includes a sampling main tube 811 disposed radially outside the discharge tube 31, which is connected to the side wall of the discharge tube 31. The side wall of the sampling main tube 811 is also provided with a sampling branch tube 812 communicating with the receiving chamber 210. The sampling spoon 82 is disposed inside the sampling main tube 811 of the sampling tube 81 and can extend into the radially inner side of the discharge tube 31 relative to the sampling main tube 811, and can move to align with the sampling branch tube 812. The sampling spoon 82 is provided with a sampling recess 821 for receiving sample material. The shape and size of the main cross-section of the sampling spoon 82 are adapted to the shape and size of the sampling tube 811, so that the sampling spoon 82 can form a seal on the sampling tube 811 when it moves inside the sampling tube 811. In addition, at the end of the sampling tube 811 opposite to the discharge pipe 31, a sampling drive component 85 is provided, which is drivenly connected to the sampling spoon 82. The sampling drive component 85 is a mechanism such as a swing cylinder that can simultaneously perform linear motion and rotation.

[0044] During the sampling process, the extending cylinder first drives the sampling spoon 82 to extend inside the discharge tube 31, allowing the sampling spoon 82 to receive the material. Then, the extending cylinder retracts, aligning the sampling recess 821 of the sampling spoon 82 with the sampling branch tube 812, and rotates the sampling spoon 82 to guide the sample from the sampling spoon 82 into the sampling branch tube 812. The sample then flows along the sampling branch tube 812 into the receiving chamber 210 and is stored in the sampling bottle 84 installed at the end of the sampling branch tube 812. Thus, the sampling device 80 forms a seal relative to the discharge tube 31, ensuring that the sampling operation itself does not affect the seal of the receiving container 90, and can be performed simultaneously with the receiving operation. This further improves the consistency between the sample and the material, and the procedure is simple and convenient, saving on the labor costs required for sampling.

[0045] In addition, the sampling device 80 also includes a vibrator 83 connected to the sampling tube 81. The vibrator 83 is located on one side of the sampling branch tube 812 and is an actuator such as a cylinder or eccentric motor capable of vibrating the sampling components. After the sample is poured into the sampling branch tube 812 by the sampling spoon 82, the vibrator 83 causes a small amount of material adhering to the tube wall to be vibrated and fall, thereby improving sample collection efficiency and avoiding mixing of samples from multiple different batches, reducing errors in the test results.

[0046] According to the embodiments of the present invention, the receiving device is provided with a main material bin, a feeding component and a receiving component connected in sequence, and a clamping mechanism is used to seal the receiving container and the feeding component, which can improve the sealing degree inside the receiving container during the feeding process, and improve the storage time and safety during the receiving and storage stages.
