Description

Technical Field

[0001] This utility model relates to the field of lithium battery anode material processing technology, and in particular to a belt dryer for lithium battery anode materials. Background Technology

[0002] An existing belt dryer for drying lithium battery anode materials, with publication number CN 221464253 U, involves adding the lithium battery anode material onto a conveyor belt inside the dryer housing. A second motor drives a rotating shaft, which in turn drives a cleaning rack to rotate, causing the cleaning rack to stir and clear the material on the conveyor belt, thus improving the uniformity of material heating. However, the aforementioned cleaning rack, by simply rotating, may cause uneven stirring of the material on the conveyor belt, thereby affecting the drying quality. Utility Model Content

[0003] The purpose of this invention is to provide a belt dryer for lithium battery anode materials in order to solve the above-mentioned problems.

[0004] This utility model achieves the above objectives through the following technical solutions:

[0005] A belt dryer for lithium battery anode materials includes a dryer housing. A conveyor belt for transferring lithium battery anode materials is installed inside the dryer housing. A turning mechanism for periodically turning the lithium battery anode materials is installed on the upper side of the conveyor belt inside the dryer housing. The turning mechanism includes a support frame fixed inside the dryer housing. Turning components are installed on both sides of the support frame. A reciprocating moving component is installed on the support frame between the turning components. Each turning component includes a mounting base fixed to the support frame. A rotating shaft is vertically installed on the mounting base. A mounting bracket is fixed to the lower end of the rotating shaft. Turning rods are spaced apart at the lower end of the mounting bracket. A gear is installed on the upper end of the rotating shaft. The reciprocating moving component includes a support shaft rotatably mounted on the support frame. Reciprocating threaded grooves are spaced apart on the support shaft, and limit rings are provided at both ends of the reciprocating threaded grooves. A connecting seat is installed on the reciprocating threaded groove. A sliding groove through which the connecting seat passes is opened on the support frame. Racks are provided at both ends of the connecting seat, meshing with the gear. A power source is connected to one end of the support shaft.

[0006] Further configuration: The mixing components are spaced apart along the longitudinal direction of the conveyor belt, and the mounting frames on both sides of the support frame are vertical, with adjacent mounting frames arranged vertically.

[0007] Further setting: The total working length of adjacent mounting frames matches the width of the conveyor belt.

[0008] Further details: The stirring rod is prismatic in shape, and the rotating shaft is rotatably connected to the mounting base.

[0009] Further features: the connecting seat and the support frame are slidably connected by a groove, and the connecting seat is threadedly connected to the reciprocating threaded groove on the support shaft.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] By using the reciprocating moving component and the tumbling component of the tumbling mechanism, the rack of the reciprocating moving component meshes with the gear on the rotating shaft during its reciprocating movement, driving the mounting frame at the lower end of the rotating shaft to rotate periodically. This alternatingly tumbles the lithium battery negative electrode material being transported on the conveyor belt, improving the drying quality. Attached Figure Description

[0023] In this embodiment: the stirring mechanism includes a support frame 31 fixed inside the dryer housing 1, stirring components are provided on both sides of the support frame 31, and a reciprocating moving component is provided on the support frame 31 between the stirring components;

[0024] The mixing assembly includes a mounting base 32 fixed on a support frame 31. A rotating shaft 33 is vertically mounted on the mounting base 32. A mounting frame 34 is fixed to the lower end of the rotating shaft 33. Tilting rods 35 are spaced apart at the lower end of the mounting frame 34. A gear 36 is mounted on the upper end of the rotating shaft 33. The mixing assembly is spaced apart along the longitudinal direction of the conveyor belt 2. The mounting frames 34 on both sides of the support frame 31 are vertically aligned, and adjacent mounting frames 34 are vertically aligned. The total working length of adjacent mounting frames 34 matches the width of the conveyor belt 2. The tilting rods 35 are prismatic in shape. The rotating shaft 33 is rotatably connected to the mounting base 32. The reciprocating motion of the assembly drives the mounting frame 34 at the lower end of the rotating shaft 33 to rotate periodically, thereby alternately mixing the lithium battery negative electrode material conveyed on the conveyor belt 2.

[0025] The reciprocating moving assembly includes a support shaft 37 rotatably mounted on a support frame 31. The support shaft 37 is provided with reciprocating threaded grooves at intervals, and limit rings are provided at both ends of the reciprocating threaded grooves.

The connecting seat 38 is slidably connected to the sliding groove 301 of the support frame 31, and the connecting seat 38 is threadedly connected to the reciprocating threaded grooves on the support shaft 37. The operation of the motor 310 drives the reciprocating threaded grooves on the support shaft 37 to rotate, so that the connecting seat 38 drives the racks 39 connected at both ends to reciprocate under the limit of the sliding groove 301. During the movement, it meshes with the gear 36 on the rotating shaft 33 and rotates, causing the entire mounting frame 34 to rotate periodically.

[0026] The working principle and usage process of this utility model are as follows: When the lithium battery negative electrode material is added to the conveyor belt 2 inside the dryer box 1 for drying and transfer, the motor 310 drives the reciprocating threaded groove on the support shaft 37 to rotate, so that the connecting seat 38 drives the rack 39 connected at both ends to move back and forth under the limit of the slide groove 301. During the movement, it meshes with the gear 36 on the rotating shaft 33 and rotates, driving the mounting bracket 34 at the lower end of the rotating shaft 33 to rotate periodically and repeatedly, thereby alternately turning over the lithium battery negative electrode material transferred on the conveyor belt 2 and improving the drying quality.

[0027] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
