Description

Technical Field

[0001] This utility model relates to the field of battery equipment technology, specifically to a scraper and homogenizing device for battery homogenization. Background Technology

[0002] In the current lithium battery slurry homogenization process, some materials agglomerate and adhere to the dispersion shaft and dispersion disc. The centrifugal force generated by the rotation of the dispersion shaft is insufficient to dislodge the material adsorbed on the shaft into the slurry. Manual scraping with a scraper is usually required to prevent changes in the weight of the materials in the slurry that could alter the formulation. Existing scrapers are typically simple rectangular scrapers. Since the dispersion shaft is cylindrical, the scraper cannot completely remove the material adhering to it when scraping around its perimeter. Furthermore, material adsorbed on the surface of the dispersion disc cannot be dislodged, and the disc's serrated edges make scraping with existing scrapers difficult. Summary of the Invention

[0003] In order to overcome the defects in the prior art, this utility model provides a scraper and a slurry homogenizing device for battery homogenization, which can improve scraping efficiency and production efficiency.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: The first aspect of this utility model discloses a scraper for battery homogenization, comprising: The scraper body includes a first scraper and a second scraper that is open and closed with the first scraper. One end of the first scraper is rotatably connected to one end of the second scraper, and the other end of the first scraper is detachably connected to the other end of the second scraper. A through hole is provided along the thickness direction of the scraper body. A handle, which is connected to the scraper body.

[0005] The above technical solution, by setting an openable scraper, can detachably sleeve the scraper on the dispersing shaft, thereby more thoroughly scraping the slurry on the dispersing shaft and dispersing disc. The structure is simple, easy to assemble and operate, and can reduce slurry waste and improve production efficiency.

[0006] Furthermore, both the first scraper and the second scraper include an upper scraper and a lower scraper, the lower scraper being perpendicular or substantially perpendicular to the upper scraper. Both the first and second scrapers have an arc-shaped groove on the opposite side of their upper scrapers, and the two arc-shaped grooves together form the through hole. The upper scraper is used to scrape off the slurry on the dispersion shaft, and the lower scraper is used to scrape off the slurry on the dispersion disc.

[0007] Furthermore, the handle is connected to the upper scraper of the first scraper. When scraping off the slurry, the operator holds the handle and pushes it to rotate the scraper along the dispersing axis.

[0008] Furthermore, one end of the first scraper and one end of the second scraper are hinged together, and the other ends of the first scraper and the second scraper are snapped together. The first scraper and the second scraper are connected by hinge and snap-fit, which facilitates the installation of the scrapers on the dispersing shaft.

[0009] Furthermore, a rotating shaft is provided at one end of the first scraper, the rotating shaft being arranged parallel to the axis of the scraper. Both ends of the rotating shaft are connected to the second scraper, allowing the second scraper to rotate around the rotating shaft. The other ends of the first and second scrapers are connected by bolts, thus enabling the opening and closing of the first and second scrapers.

[0010] Furthermore, a handle is provided at the end of the handle opposite to the scraper body. The handle facilitates the operator in rotating the handle.

[0011] The second aspect of this utility model discloses a slurry homogenizing device for batteries, comprising: A mixer, comprising a stirring paddle, a dispersing shaft, and a dispersing disc, wherein the dispersing disc is connected to the dispersing shaft and is disposed at the bottom of the dispersing shaft; A mixing tank, wherein the mixing tank is height-adjustable; And a scraper as described in any of the first aspects, the scraper being sleeved on the dispersion shaft through a through hole in the scraper body and movable up and down along the dispersion shaft.

[0012] Furthermore, the diameter of the through hole is larger than the diameter of the dispersing shaft, so that the scraper can move up and down along the dispersing shaft to scrape off the slurry.

[0013] Furthermore, the lower scraper is higher than the height of the dispersing disc, and its length is less than the radius of the dispersing disc. This allows the lower scraper to rotate on the surface of the dispersing disc and scrape off the slurry.

[0014] Furthermore, the handle of the scraper is longer than the radius of the mixing tank, so that the operator can easily rotate the handle around the mixing tank.

[0015] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art: 1. This application, by setting an openable scraper, can fit the scraper on the dispersing shaft, so that the scraper can move up and down along the dispersing shaft, thereby more thoroughly scraping the material on the dispersing shaft and dispersing disc, reducing material waste and improving production efficiency.

[0016] 2. The scraper structure in this application is simple, easy to assemble and operate, and can reduce the scraping time from 20 minutes to 5 minutes, increasing the scraping efficiency by 70%. Furthermore, the handle design allows workers to avoid contact with the slurry during the scraping process, making it safe and environmentally friendly.

[0024] Reference Figures 1-4 As shown in the figure, this application provides a scraper for battery homogenization. The scraper includes a scraper body 1 and a handle 4. The scraper body 1 is used to scrape off the slurry. The handle 4 is connected to the scraper body 1. When the operator pushes the handle 4 to rotate, it drives the scraper body 1 to rotate and move.

[0025] The scraper body 1 is used to scrape off the slurry and is usually made of corrosion-resistant material, such as polytetrafluoroethylene. The shape and size of the scraper body 1 can be flexibly set. Battery homogenization involves stirring the slurry used in the battery process.

[0026] like Figure 1 and Figure 2 As shown, the scraper body 1 includes a first scraper 2 and a second scraper 3 that is open and closed with the first scraper 2. One end of the first scraper 2 is rotatably connected to one end of the second scraper 3, and the other end of the first scraper 2 is detachably connected to the other end of the second scraper 3. When the first scraper 2 and the second scraper 3 are closed, a through hole is provided along the thickness direction of the scraper body 1. The through hole is used to fit the scraper body 1 onto other devices. The size and shape of the through hole are flexibly set according to the device on which it is fitted.

[0027] like Figure 2As shown, both the first scraper 2 and the second scraper 3 include an upper scraper 8 and a lower scraper 9 located below the upper scraper 8. The lower scraper 9 is perpendicular or approximately perpendicular to the upper scraper 8. One end of the lower scraper 9 is flush with the through hole. Both the upper scraper 8 of the first scraper 2 and the second scraper 3 are provided with arc-shaped grooves on opposite sides. The arc-shaped grooves extend in a direction perpendicular to the thickness direction of the upper scraper 8. The two arc-shaped grooves enclose the through hole.

[0028] In the embodiments of this application, a rotating shaft 7 is provided at one end of the first scraper 2. The rotating shaft 7 is arranged parallel to the axial direction of the scraper body 1. Both ends of the rotating shaft 7 are connected to the second scraper 3. The second scraper 3 can rotate around the rotating shaft 7. The other end of the first scraper 2 and the other end of the second scraper 3 are provided with protrusions for bolts 6 to pass through. The bolts 6 pass through the protrusions to connect the first scraper 2 and the second scraper 3, thereby realizing the opening and closing of the first scraper 2 and the second scraper 3.

[0029] In another possible embodiment, one end of the first scraper 2 and one end of the second scraper 3 are hinged together, and the other end of the first scraper 2 and the other end of the second scraper 3 are snapped together, thereby enabling the second scraper 3 to rotate about the hinge point so as to install the scraper body 1 on other devices.

[0030] In other possible embodiments, the rotating shaft can be replaced with other connecting parts that can rotatably connect the first scraper 2 and the second scraper 3, and the bolts and clips can also be replaced with other connecting parts that can detach and connect the first scraper 2 and the second scraper 3. Examples are not listed here.

[0031] To make it easier for staff to hold the handle, such as Figures 1 to 3 As shown, the handle 4 is provided with a handle 5 at one end away from the scraper body 1. The handle 4 can be connected to either the first scraper 2 or the second scraper 3. In the embodiment of this application, the handle 4 is connected to the upper scraper 8 of the first scraper 2.

[0032] This application also provides a battery homogenizing apparatus, comprising: The mixer includes a stirring paddle, a dispersing shaft 10, and a dispersing disc 11, as shown below. Figure 3 As shown, the dispersion disk 11 is connected to the dispersion shaft 10 and is located at the bottom of the dispersion shaft 10; The mixing tank is height-adjustable. When mixing is required, the mixing tank rises and connects to the mixer. When scraping off the slurry is required, the mixing tank descends and the scraper described in the above embodiment is sleeved on the dispersing shaft 10 through the through hole on the scraper body 1. The scraper moves up and down along the dispersing shaft 10 under the push of the operator.

[0033] To facilitate the up-and-down movement of the scraper body 1 along the dispersing shaft 10, the diameter of the through hole on the scraper body 1 is larger than the diameter of the dispersing shaft 10. The scraping effect is best when the diameter of the through hole on the scraper body 1 is 1 to 3 mm larger than the diameter of the dispersing shaft 10.

[0034] like Figure 3 and Figure 4 As shown, the dispersing disc 11 has a certain height. In order to ensure the scraping effect, the height of the lower scraper 9 is higher than the height of the dispersing disc 11, and the length of the lower scraper 9 is less than the radius of the dispersing disc 11, so that the lower scraper 9 can rotate along the dispersing axis 10 on the surface of the dispersing disc 11 to scrape off the slurry on the surface of the dispersing disc 11.

[0035] To facilitate the rotation of handle 4, the length of handle 4 is greater than the radius of the mixing bowl.

[0036] In use, separate the first scraper 2 and the second scraper 3, put them on the dispersing shaft 10 and tighten the bolt 6. The operator holds the handle 5 and rotates the scraper, so that the scraper body 1 moves from top to bottom on the dispersing shaft 10, so that the scraped slurry falls down automatically. When the scraper body 1 moves to the point where the lower scraper 9 contacts the surface of the dispersing disc 11, continue to push the handle 4 to rotate to scrape off the slurry on the dispersing disc 11. After scraping is completed, remove the bolt 5, take off the scraper, and continue to homogenize and stir the slurry.

[0037] The scraper in this embodiment is not only simple in structure and easy to operate, but also easy to clean.
