Description

Technical Field

[0001] This utility model relates to the field of engineering machinery, specifically to a material discharge device. Background Technology

[0002] In the field of lithium-ion battery manufacturing, carbon nanotubes, as a novel conductive agent material, are widely used in cathode material systems due to their excellent conductivity and mechanical properties. Carbon nanotube slurry is typically transported in large 1000L metal containers. Upon arrival at the production site, manual transfer of the material is required: operators must open the container lid and use a vacuum suction device to pump the slurry to a storage tank for temporary storage. This process exposes several safety hazards: First, the main component of carbon nanotubes is N-methylpyrrolidone, which has a certain degree of toxicity and strong decomposition; manual opening of the lid can easily cause the release of volatile organic compounds. Second, there is a risk of slurry splashing when the suction pipe is inserted into the container, which can cause chemical burns upon skin contact. Third, the existing container structure easily leads to material residue, resulting in both raw material waste and the challenge of hazardous waste disposal. Therefore, providing a rapid and safe discharge device is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0046] The technical solution of this application will now be described in detail with reference to the accompanying drawings.

[0047] like Figures 1 to 8 As shown in the figure, this utility model embodiment provides a discharge device that addresses the technical problems of inconvenient discharge of barrelled materials and the potential for safety accidents in the prior art.

[0048] First, the discharge device includes a storage container 1, a suction component and a drive component. The storage container 1 contains the material to be discharged. In some embodiments, the storage container 1 can be a ton-shaped structure with a volume of 1000L, used to load carbon nanotubes, the raw material for lithium batteries. The storage container 1 has a first discharge port 11 at its top; the suction assembly includes a suction pipe 2, the suction port 21 of the suction pipe 2 is set corresponding to the first discharge port 11, and at least a portion of the suction pipe 2 is configured to enter or exit the storage container 1 from the first discharge port 11; the drive assembly includes a height drive mechanism 31, a rotation drive mechanism 32 and a bracket 33, the suction pipe 2 is fixed to the bracket 33 and the suction port 21 of the suction pipe 2 is aligned with the first discharge port 11, the rotation drive mechanism 32 is connected to the bracket 33 and can make the suction pipe 2 rotate at an angle relative to the central axis of the first discharge port 11, so that the suction port 21 of the suction pipe 2 can be angularly offset inside the storage container 1, so as to clean the material in the storage container 1 and improve the suction efficiency; the height drive mechanism 31 is connected to the bracket 33 and can make the suction pipe 2 move along a first direction so that the suction port 21 of the suction pipe 2 enters or exits the storage container 1 from the first discharge port 11. During the material suction process, since the suction pipe 2 can move along the first direction, when the liquid level of the material in the storage container 1 is lower than the suction port 21, the suction pipe 2 can be moved downwards, moving the suction port 21 below the liquid level to avoid the inability to suction material. It should be noted that the first direction is preferably a direction parallel to the vertical direction, such as... Figure 3 As shown; it can also be a direction that forms an angle with the vertical direction, as long as the suction port 21 of the suction pipe 2 can enter or exit the storage container 1 from the first discharge port 11.

[0049] As can be seen, the storage container 1 of this embodiment is provided with a first discharge port 11 at the top, which can be used in conjunction with the suction pipe 2 for suction. The height driving mechanism 31 can drive the suction pipe 2 to enter or exit the storage container 1 from the first suction port 21, avoiding manual operation and preventing the material in the storage container 1 from contacting the operator and causing skin burns, thus improving the safety of material discharge from the container. Furthermore, the rotation driving mechanism 32 can drive the suction pipe 2 to rotate at an angle relative to the central axis of the first discharge port 11, so that the suction port 21 of the suction pipe 2 can be offset at an angle within the storage container 1, which can more thoroughly suction the material in the storage container 1.

[0050] Specifically, such as Figure 1 and Figure 2As shown, the support 33 is located above the storage container 1, and the driving end of the rotary drive mechanism 32 is connected to at least one end of the support 33 along the second direction (i.e., along the second direction, one end of the support 33 is connected to the driving end of the rotary drive mechanism 32; or along the second direction, each end of the support 33 is connected to a rotary drive mechanism 32, as shown). Figure 1 As shown), the drive mechanism 31 is used to drive the support 33 and the suction pipe 2 to rotate at an angle relative to the central axis of the first discharge port 11. The drive end of the height drive mechanism 31 is connected to at least one end of the support 33 along the first direction (i.e., along the first direction, one end of the support 33 is connected to the drive end of the height drive mechanism 31; or, along the first direction, both ends of the support 33 are respectively connected to a height drive mechanism 31, such as...). Figure 1 As shown), it is used to drive the support 33 and the suction pipe 2 to move along the first direction. It should be noted that the second direction is preferably parallel to the direction of the plane where the first discharge port 11 is located, such as... Figure 3 As shown; it can also be a direction that forms an angle with the plane where the first discharge port 11 is located, as long as the suction port 21 of the suction pipe 2 can enter or exit the storage container 1 from the first discharge port 11 and the suction pipe 2 can rotate at an angle relative to the central axis of the first discharge port 11.

[0051] The discharge device also includes a scraping mechanism 4 and a support mechanism 5. The scraping mechanism 4 is sleeved on the suction pipe 2 and can move relative to the suction pipe 2 along the central axis of the suction pipe 2. It can scrape off the material adhering to the outer wall of the suction pipe 2, so that the outer wall of the suction pipe 2 is free of material. The support mechanism 5 is arranged on the side of the suction pipe 2 near the storage container 1. The support mechanism 5 is used to fix the scraping mechanism 4 when the suction pipe 2 moves out of the storage container 1 from the first discharge port 11. That is, during the process of the suction pipe 2 moving out of the first discharge port 11, the support mechanism 5 fixes the scraping mechanism 4 to keep its position unchanged, thereby realizing the relative movement between the suction pipe 2 and the scraping mechanism 4 to scrape off the material on the outer wall of the suction pipe 2.

[0052] In specific implementation, such as Figure 6 As shown, the scraping mechanism 4 includes a scraper 41, a first limiting member 42, and a second limiting member 43. The scraper 41 can be cylindrical and is sleeved on the outer wall of the suction pipe 2, with an interference fit. This interference fit ensures a tight connection between the scraper 41 and the suction pipe 2, preventing them from easily sliding relative to each other. A certain external force is required to achieve relative sliding, thus ensuring the scraping function. The first limiting member 42 is connected to one side of the scraper 41 along the central axis of the suction pipe 2; the second limiting member 43 is connected to the other side of the scraper 41 along the central axis of the suction pipe 2. The longitudinal section of the scraping mechanism 4 is I-shaped.

[0053] The support mechanism 5 can clamp the scraper 41 between the first limiting member 42 and the second limiting member 43. The I-shaped structure facilitates the clamping connection between the support mechanism 5 and the scraping mechanism 4. The outer diameter of the second limiting member 43 is smaller than the outer diameter of the first limiting member 42 to prevent the second limiting member 43 from colliding with the first detection mechanism 54 on the support mechanism 5. It should be noted that the description of the outer diameter refers to the definition of the size of the component when the component is circular. When at least one of the first limiting member 42 and the second limiting member 43 is square, polygonal, or other shapes, the dimensional relationship between the first limiting member 42 and the second limiting member 43 only needs to prevent the second limiting member 43 from colliding with the first detection mechanism 54 on the support mechanism 5.

[0054] At least one first stop 44 is provided on the outer peripheral wall of the second limiting member 43. The distance between the outermost edge of the first stop 44 and the central axis of the suction pipe 2 is greater than the radius of the first discharge port 11, ensuring that the size of the scraping mechanism 4 is larger than the size of the first discharge port 11, and the scraping mechanism 4 will not enter the storage container 1. It should be noted that the first stop 44 can be a ring-shaped component sleeved on the outside of the second limiting member 43; or the first stop 44 can be a separate component connected to the circumferential outer wall of the second limiting member 43. The first stop 44 can be one, two, or more. Figure 4 As shown, four first stop members 44 are evenly arranged along the circumferential outer wall of the second limiting member 43. Furthermore, the structural shape of the first stop members 44 can be regular or irregular, and those skilled in the art can design them specifically according to actual needs.

[0055] In specific implementation, such as Figure 6 As shown, the scraping mechanism 4 also includes at least one second stop 45. The second stop 45 is disposed on the surface of the second limiting member 43 away from the first limiting member 42. The first end of the second stop 45 is movably connected to the second limiting member 43, and the second end of the second stop 45 extends toward the central axis of the suction pipe 2. The second end of the second stop 45 can stop below the suction port 21 of the suction pipe 2 to block the suction port 21, which can prevent foreign objects from entering the suction pipe 2 from the suction port 21 and also prevent residual material in the suction pipe 2 from dripping.

[0056] In specific implementation, a torsion spring 47 is fixed to the side of the second limiting member 43 away from the first limiting member 42. The second stop member 45 is connected via the torsion spring 47. The second stop member 45 includes, but is not limited to, a hollow sphere. One, two, or more second stop members 45 can be provided. When two second stop members 45 are provided, each is connected to the second limiting member 43 via a torsion spring 47. The torsion spring 47 self-tightens inward, and the two second stop members 45 form a component with a load-bearing space. When multiple second stop members 45 are provided, each is connected to the second limiting member 43 via a torsion spring 47. The torsion spring 47 self-tightens inward, and the multiple second stop members 45 form a component with a load-bearing space. Figure 6 and Figure 7 As shown, there are two second stop members 45, and each second stop member 45 is a 1 / 4 hollow sphere.

[0057] In specific implementation, such as Figure 4 As shown, the scraper 41 includes a scraper blade 48, a pressure plate 46, and fasteners. The scraper blade 48 is interference-fitted to the outer wall of the suction pipe 2. The scraper blade 48 adheres to the surface of the second limiting member 43 away from the first limiting member 42, and the pressure plate 46 adheres to the surface of the scraper blade 48 away from the second limiting member 43. The pressure plate 46, scraper blade 48, and second limiting member 43 are fixed together by fasteners. Fasteners include, but are not limited to, bolts. The scraper blade 48 can be made of a soft material resistant to strong organic solvents. In other embodiments, the scraper blade 48 and pressure plate 46 can also be disposed on the first limiting member 42, with the scraper blade 48 adhering to the surface of the first limiting member 42 away from the second limiting member 43, and the pressure plate 46 adhering to the surface of the scraper blade 48 away from the first limiting member 42. The pressure plate 46, scraper blade 48, and first limiting member 42 are fixed together by fasteners. Furthermore, when the suction pipe 2 moves relative to the scraping mechanism 4, the scraper 48 can be used to scrape the material off the outer wall of the suction pipe 2.

[0058] In specific implementation, such as Figure 8As shown, the support mechanism 5 includes a support base 51, a horizontal drive mechanism 52, a clamping mechanism 53, and a first detection mechanism 54. The support base 51 is located near the storage container 1. The horizontal drive mechanism 52 is fixed to the top of the support base 51, and its drive end faces the suction pipe 2. The clamping mechanism 53 is fixed to the drive end of the horizontal drive mechanism 52. The horizontal drive mechanism 52 drives the clamping mechanism 53 to move towards or away from the suction pipe 2. The clamping mechanism 53 can clamp between the first limiting member 42 and the second limiting member 43 of the scraping mechanism 4. The first detection mechanism 54 is fixed to the top of the horizontal drive mechanism 52 and is used to detect whether the first limiting member 42 has moved into place. It should be noted that the clamping mechanism 53 includes, but is not limited to, a U-shaped fork, and the first detection mechanism 54 includes, but is not limited to, a photoelectric sensor. Taking the first detection mechanism 54, which uses a photoelectric sensor, as an example, the operation process of the detection mechanism will be explained. When the first limiting member 42 contacts the photoelectric sensor, the sensor light illuminates, indicating that the first limiting member 42 has reached the designated position. The first limiting member 42 is a circular component to facilitate contact with the photoelectric sensor.

[0059] In specific implementation, the suction pipe 2 is provided with a third limiting member 6. The third limiting member 6 is located on one side of the scraping mechanism 4 along the central axis of the suction pipe 2. The third limiting member 6 is configured in the suction pipe 2 such that when the scraping mechanism 4 is limited by the third limiting member 6, the first detection mechanism 54 can detect the first limiting member 42 and limit the scraping mechanism 4.

[0060] In specific implementation, the two ends of the bracket 33 are connected to support members 34, which can improve the stability of the bracket 33. The two ends of the bracket 33 are connected to the support members 34 through bearings. A rotary drive mechanism 32 is fixed on one of the support members 34, and the drive end of the rotary drive mechanism 32 is drivenly connected to the bracket 33. The height drive mechanism 31 includes two symmetrically arranged on both sides of the storage container 1. The drive ends of the two height drive mechanisms 31 are respectively connected to the support members 34 located at both ends of the bracket 33 along the first direction.

[0061] In specific implementation, a second discharge port 12 is provided near the bottom of the storage container 1. The second discharge port 12 is located on the side wall of the storage container 1 away from the support mechanism 5, and the suction port 21 of the suction pipe 2 is inclined towards the second discharge port 12, which allows for inclined suction, making it easier for the suction port 21 to contact the bottom of the storage container 1, and reducing the amount of residual material in the storage container 1. It should be noted that the suction port 21 of the suction pipe 2 is preferably a flared opening, that is, the opening size of the suction port 21 near the end of the storage container 1 gradually decreases in the direction away from the storage container 1. The flared opening can prevent the scraping mechanism 4 from falling off, and the flared opening is inclined towards the pushing position of the storage container 1 (e.g., Figure 5As shown, the side without the second baffle 7112 in the fourth direction is the advancing position of the storage container 1. The rotation of the rotating mechanism causes the suction pipe 2 to shift at an angle. The lowest point is the bottom of the storage container 1 near the second discharge port 12. By tilting the suction pipe 2 and inserting it close to the lowest point of the bottom of the storage container 1, the material in the storage container 1 is sucked up more cleanly.

[0062] In specific implementation, such as Figure 5 As shown, the discharge device also includes a base 7, which includes a fixing plate 71 and a weighing device 72. The fixing plate 71 is fixed to the surface of the weighing device 72. A limiting baffle 711 is provided on the fixing plate 71. The limiting baffle 711 and the fixing plate 71 form a limiting space for the storage container 1. A second detection mechanism 712 is provided on the limiting baffle 711 to detect whether the storage container 1 has moved into position. It should be noted that the material suction process of the storage container 1 is linked to the weight in real time, and the position of the suction pipe 2 is adjusted according to the weight of the storage container 1.

[0063] In specific implementation, such as Figure 5 As shown, the limiting baffle 711 includes a first baffle 7111 and a second baffle 7112. The first baffle 7111 is positioned along a third direction, limiting the material container to both sides of the device. The second baffle 7112 is positioned along a fourth direction, limiting the material container to one side of the device. The gap between the first baffles 7111 on both sides of the material container along the third direction is used to accommodate the material container. The third and fourth directions are perpendicular. A second detection mechanism 712 is provided on the second baffle 7112. It should be noted that the second detection mechanism 712 includes, but is not limited to, a photoelectric sensor. When a photoelectric sensor is used, when the storage container 1 is close to the second baffle 7112, the photoelectric sensor lights up, indicating whether the storage container 1 is placed in the correct position. Furthermore, the specific number and position of the second detection mechanism 712 can be designed by those skilled in the art according to actual needs, as long as it can detect whether the storage container 1 has moved into place.

[0064] In practice, the top of the storage container 1 has a storage container cover, which is threaded and integrally engaged with the storage container 1.

[0065] In practice, the operation of the storage device is as follows:

[0066] The storage container 1 is placed on the base 7 and pushed into place. The sensor light of the second detection mechanism 712 illuminates or emits other indications.

[0067] The storage container cover at the first discharge port 11 of the storage container 1 is opened manually or by an automatic opening mechanism.

[0068] When the suction is initiated, the scraping mechanism 4 is at the bottom of the suction pipe 2, and the second stop 45 covers the suction port 21 of the suction pipe 2, which can prevent residual material in the suction pipe 2 from falling back and also prevent some foreign objects from entering. When the suction is initiated, the height drive mechanism 31 drives the suction pipe 2 into the discharge container, and the first stop 44 of the scraping mechanism 4 contacts the storage container 1 first.

[0069] As the height drive mechanism 31 descends, the scraping mechanism 4 approaches the third limiting member 6 on the suction pipe 2;

[0070] The end of the suction pipe 2 away from the suction port 21 is connected to the suction pump. The weighing device 72 on the base 7 senses the amount of material residue in the storage container 1. When the amount of residue is small, the rotary drive mechanism 32 drives the suction pipe 2 to tilt, and the suction port 21 of the suction pipe 2 is biased toward the position of the second discharge port 12 of the storage container 1. The scraping mechanism 4 reaches the third limiting member 6 on the suction pipe 2.

[0071] When the material suction ends, the rotary drive mechanism 32 drives the suction pipe 2 from the inclined position back to the upright position, adjusting the suction pipe 2 to a vertical state, and the sensor light of the first detection mechanism 54 lights up or issues other indications.

[0072] The horizontal drive mechanism 52 drives the clamping mechanism 53 to engage between the first limiting member 42 and the second limiting member 43;

[0073] The height drive mechanism 31 drives the suction pipe 2 to move out of the storage container 1. The scraping mechanism 4 uses the lifting force of the height drive mechanism 31 to slide to the bottom of the suction pipe 2. The scraper 48 of the scraping mechanism 4 scrapes off the material attached to the outer wall of the suction pipe 2 and falls back into the storage container 1.

[0074] The scraping mechanism 4 reaches the bottom of the suction pipe 2, and the second stop 45 blocks the suction port 21; the horizontal drive mechanism 52 drives the clamping mechanism 53 to disengage from the scraping structure, and the overall suction ends.
