Description

Technical Field

[0001] This application relates to the technical field of separation devices, and in particular to a ball-powder separation device for battery materials. Background Technology

[0002] Battery materials are a mixture and a highly sensitive and flammable material. During the manufacturing process, mixing pellets are added to the battery materials to disperse them and prevent clumping. After mixing, the mixing pellets and powder need to be separated. Traditional separation methods are usually manual, which has the disadvantage of leaving a large amount of residual material on the mixing pellets. Furthermore, due to the high sensitivity and flammability of battery materials, manual separation poses a safety hazard of material combustion. Utility Model Content

[0003] In order to reduce the amount of material remaining on the mixed spheres after separation, this application provides a sphere-powder separation device for battery materials.

[0004] The ball-powder separation device for battery materials provided in this application adopts the following technical solution:

[0005] A spherical powder separation device for battery materials includes a funnel assembly and a separation mechanism;

[0006] The funnel assembly includes a feeding funnel, a separating funnel, and a spherical discharge funnel. The separating funnel includes an interconnected installation chamber and a powder discharge funnel. The powder discharge funnel is fixedly installed below the installation chamber, the feeding funnel is fixedly installed at the top of the installation chamber, and the spherical discharge funnel is fixedly installed on the side wall of the separating funnel and extends into the interior of the separating funnel.

[0007] The separation mechanism includes a drive component, a rotating shaft, a feeding cylinder, and a roller. The drive component is disposed on the outer wall of the installation chamber and is used to drive the rotating shaft to rotate. The rotating shaft is disposed inside the installation chamber, with one end of the rotating shaft connected to the drive component and the other end of the rotating shaft rotatably connected to the inner wall of the installation chamber.

[0008] The roller includes a connecting ring and multiple first rods. The multiple first rods form a cylindrical shape and there are gaps between adjacent first rods. The connecting ring is sleeved on all the first rods and fixedly connected to the first rods. The rotating shaft passes through the roller and is fixedly connected to the roller through multiple support rods. The roller and the rotating shaft are coaxial and inclined. The lowest end of the roller is located above the discharge funnel and is connected to the discharge funnel.

[0009] The feeding cylinder is arc-shaped, with its top end fixedly connected to the top wall of the installation chamber and communicating with the feeding funnel. The bottom end of the feeding cylinder extends into the drum, and the rotating shaft passes through the feeding cylinder.

[0010] By adopting the above technical solution, during the separation of spheres and powder, battery material with mixed spheres is added to the feeding hopper, and then passes through the feeding cylinder and the drum in sequence. The drum rotates continuously around its own axis through the driving component. Under the action of centrifugal force, the powder of the sphere-powder mixture falls from the gap between the first rods and enters the powder discharge hopper. At the same time, the powder adhering to the mixing spheres can also be detached under continuous rotation and friction with the first rods, which helps to reduce the amount of material remaining on the mixing spheres after separation. The powder-free mixing spheres fall from the lowest end of the drum into the sphere discharge hopper for discharge, realizing the separation of spheres and powder. The operation is simple and highly automated.

[0011] Optionally, the feeding cylinder is formed by multiple second rods forming a cylindrical structure, with gaps between adjacent second rods.

[0012] By adopting the above technical solution, the powder can fall from the gap between the second rods when passing through the feeding cylinder.

[0013] Optionally, a flow block is sleeved on and connected to the rotating shaft located inside the drum.

[0014] By adopting the above technical solution, the flow block can block the falling of the ball-powder mixture in the drum, thereby increasing the residence time of the ball-powder mixture in the drum, and further reducing the amount of powder carried away by the mixing ball and reducing the amount of residual material on the mixing ball.

[0015] Optionally, the drive component includes an air motor and a coupling. The rotating shaft of the air motor is connected to the highest end of the rotating shaft via the coupling, and the two ends of the rotating shaft are rotatably connected to the side wall of the installation chamber via bearings.

[0016] By adopting the above technical solutions, the structure can be simplified and manufacturing and usage costs can be reduced.

[0017] Optionally, the coupling is fitted with a sealing sleeve, one end of which is connected to the air motor, and the other end of which is fixedly connected to the bearing at the highest point of the rotating shaft.

[0018] Optionally, silicone gaskets are used to seal the feeding funnel and the separation funnel, as well as the spherical discharge funnel and the separation funnel.

[0019] Optionally, the inner walls of the feeding funnel, the separating funnel, and the spherical discharge funnel are all mirror-finished, and the included angle between the feeding funnel, the separating funnel, and the spherical discharge funnel is not less than 60°.

[0020] By adopting the above technical solution, the inner walls of the feeding funnel, the separation funnel, and the spherical discharge funnel are all mirror-finished, which reduces the coefficient of friction of the inner wall of the funnel. At the same time, the included angle between the feeding funnel, the separation funnel, and the spherical discharge funnel is not less than 60°, which reduces the probability of powder adhering to the inner wall of the funnel assembly.

[0021] Optionally, the lowest end of the roller is tapered inward.

[0022] By adopting the above technical solution, it is easier for the spheres to enter the sphere discharge funnel in a concentrated manner.

[0023] Optionally, the funnel assembly, rotating shaft, feeding cylinder, and roller are all made of stainless steel.

[0024] By adopting the above technical solution, the risk of combustion caused by ball powder impact can be prevented.

[0025] In summary, this application includes at least the following beneficial technical effects:

[0026] The ball powder separation device of this application has stable and reliable performance, long service life, good separation effect, convenient separation and low operating cost. Attached Figure Description

[0030] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0031] A spherical-powder separation device for battery materials includes a funnel assembly and a separation mechanism. The funnel assembly includes a feeding funnel 1, a separation funnel 2, and a spherical discharge funnel 3. The separation funnel 2 includes an interconnected installation chamber 21 and a powder discharge funnel 22. The powder discharge funnel 22 is fixedly installed below the installation chamber 21, the feeding funnel 1 is fixedly installed at the top of the installation chamber 21, and the spherical discharge funnel 3 is fixedly installed on the side wall of the separation funnel 2 and extends into the interior of the separation funnel 2.

[0032] The separation mechanism includes a drive component 4, a rotating shaft 5, a feeding cylinder 6, and a roller 7. The drive component 4 is disposed on the outer wall of the mounting chamber 21 and is used to drive the rotating shaft 5 to rotate. The rotating shaft 5 is disposed inside the mounting chamber 21, with one end of the rotating shaft 5 connected to the drive component 4 and the other end of the rotating shaft 5 rotatably connected to the inner wall of the mounting chamber 21.

[0033] The roller 7 includes a connecting ring 71 and multiple first rods 72. The multiple first rods 72 form a cylindrical shape and there are gaps between adjacent first rods 72. The connecting ring 71 is sleeved on all the first rods 72 and fixedly connected to the first rods 72. The rotating shaft 5 passes through the roller 7 and is fixedly connected to the roller 7 through multiple support rods. The roller 7 and the rotating shaft 5 are coaxially arranged and inclined. The lowest end of the roller 7 is located above the discharge funnel and is connected to the discharge funnel. The feeding cylinder 6 is arc-shaped. The top end of the feeding cylinder 6 is fixedly connected to the top wall inside the installation chamber 21 and communicates with the feeding funnel 1. The bottom end of the feeding cylinder 6 extends into the roller 7, and the rotating shaft 5 passes through the feeding cylinder 6.

[0034] During the ball-powder separation process, battery material containing mixed balls is added to the feeding hopper 1, and then passes through the feeding cylinder 6 and the roller 7 in sequence. The roller 7 rotates continuously around its own axis through the driving component 4. Under the action of centrifugal force, the powder of the ball-powder mixture falls from the gap between the first rods 72 and enters the powder discharge hopper 22. At the same time, the powder adhering to the mixed balls can also be detached under continuous rotation and friction with the first rods 72, which helps to reduce the amount of material remaining on the mixed balls after separation. The powdered mixed balls fall from the lowest end of the roller 7 into the ball discharge hopper 3 for discharge, realizing ball-powder separation. The operation is simple and highly automated.

[0035] The feeding cylinder 6 is formed by multiple second rods 61 arranged in a cylindrical structure, with gaps between adjacent second rods 61. Powder falls through the gaps between the second rods 61 as it passes through the feeding cylinder 6. A flow block 8 is fitted onto and connected to the rotating shaft 5 located inside the drum 7. The flow block 8 obstructs the fall of the ball-powder mixture in the drum 7, thereby increasing the residence time of the ball-powder mixture in the drum 7, further reducing the amount of powder carried away by the mixing balls and reducing the amount of residual material on the mixing balls. Both the first rod 72 and the second rod 61 are made of round steel to reduce the contact area between the balls and the drum 7.

[0036] The drive component 4 includes an air motor 41 and a coupling 42. The shaft of the air motor 41 is connected to the highest end of the rotating shaft 5 via the coupling 42. Both ends of the rotating shaft 5 are rotatably connected to the side wall of the mounting chamber 21 via bearings 211, thereby simplifying the structure and reducing manufacturing and usage costs. A sealing sleeve 9 is fitted over the coupling 42. One end of the sealing sleeve 9 is connected to the air motor 41, and the other end of the sealing sleeve 9 is fixedly connected to the bearing 211 at the highest end of the rotating shaft 5.

[0037] Silicone gaskets are used to seal the connection between the feeding funnel 1 and the separating funnel 2, and between the ball discharge funnel 3 and the separating funnel 2. The inner walls of the feeding funnel 1, separating funnel 2, and ball discharge funnel 3 are all mirror-finished, resulting in a low coefficient of friction. The included angle between the feeding funnel 1, separating funnel 2, and ball discharge funnel 3 is not less than 60°; in this embodiment, the included angle is 65°. This reduces the likelihood of powder adhering to the inner wall of the funnel assembly. The lowest point of the roller 7 tapers inwards, facilitating the concentrated entry of the balls into the ball discharge funnel 3. The funnel assembly, rotating shaft 5, feeding cylinder 6, and roller 7 are all made of stainless steel to prevent the risk of combustion caused by the impact of the powder balls.

[0038] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
