[0025] Example

[0026] Reference Figures 1-4 This is an embodiment of the present invention, which provides a gradient doping and mixing device for high energy density and high efficiency anode materials, comprising:

[0027] The main body 100 includes a housing 101, a feeding trough 102 disposed on the top of the housing 101, a feeding funnel 103 fixedly connected to the top of the feeding trough 102, a discharge slot 104 opened on one side of the housing 101, a fixing slot 105 disposed on the other side of the housing 101, and a discharge assembly 107 fixedly connected to the inner wall of the discharge slot 104.

[0028] The stirring mechanism 200 includes a connecting groove 201 formed on the inner wall of the outer shell 101, a stirring chamber 202 welded to the surface of the connecting groove 201, a limiting groove 203 formed on the top of the outer shell 101, and a stirring assembly 204 fixedly connected to the top of the limiting groove 203.

[0029] The feeding assembly 107 includes a feeding chute 107a fixedly connected to the inner wall of the feeding slot 104, a drain outlet 107b penetrating the top of the feeding chute 107a, a sleeve rod 107c welded to the side wall slot of the feeding chute 107a, a connecting arm 107f inserted into the inner cavity of the sleeve rod 107c, and a baffle plate 107g fixedly connected to the end of the connecting arm 107f; the feeding assembly 107 also includes a first drive motor 107d fixedly connected to the bottom of the inner cavity of the sleeve rod 107c, and a lead screw 107e adapted to be installed at the output end of the first drive motor 107d.

[0030] Specifically, the main body 100 forms a smooth material passage through the feeding funnel 103 and the feeding component 107, improving the feeding and discharging efficiency; the mixing mechanism 200 fixes the mixing component 204 with the limiting groove 203, and works with the mixing chamber 202 to achieve stable mixing operation and enhance the mixing uniformity; in the feeding component 107, the first drive motor 107d drives the lead screw 107e to drive the connecting arm 107f and the baffle plate 107g in linkage, which can accurately control the feeding amount and flow rate, and the plug-in structure of the sleeve rod 107c and the connecting arm 107f improves the operational stability.

[0031] Furthermore, the lead screw 107e is used in conjunction with the connecting arm 107f, and the connecting arm 107f is sleeved on the surface of the lead screw 107e; the main body mechanism 100 also includes a trapezoidal block 106 welded to the bottom of the inner cavity of the outer shell 101, and the trapezoidal block 106 is used in conjunction with the discharge chute 107a, with the top of the trapezoidal block 106 fixedly connected to the bottom of the discharge chute 107a; the connecting groove 201 is used in conjunction with the stirring chamber 202, and the inner diameter of the connecting groove 201 is the same as the outer diameter of the stirring chamber 202.

[0032] Preferably, the trapezoidal block 106 is fixedly connected to the discharge chute 107a, which enhances the structural stability and guides the material to gather, avoiding residue; the connecting groove 201 and the mixing chamber 202 are matched with the same diameter to ensure that the mixing chamber 202 is installed firmly and reduce shaking during operation.

[0033] It should be noted that the stirring assembly 204 includes a second drive motor 204a fixedly connected to the top of the limiting groove 203, a rotating shaft 204b adapted to be installed at the output end of the second drive motor 204a, and a first stirring blade 204c fixedly connected to the surface of the rotating shaft 204b; the stirring assembly 204 also includes a through hole 204d opened on the surface of the first stirring blade 204c, and a second stirring blade 204e welded to the bottom of the rotating shaft 204b.

[0034] The stirring assembly 204 is driven by a second drive motor 204a to drive a rotating shaft 204b, which in turn drives the first stirring blade 204c and the second stirring blade 204e to work together to form a three-dimensional stirring effect. The through holes 204d on the surface of the first stirring blade 204c disperse the material flow during rotation, enhancing the disturbance effect. The second stirring blade 204e focuses on stirring the material at the bottom to prevent sedimentation and accumulation. The double blade combination covers different height areas of the stirring chamber 202, improving the uniformity of mixing. The matching installation of the motor output end and the rotating shaft 204b ensures smooth power transmission.

[0035] In use, the material enters the feeding trough 102 through the feeding funnel 103 and falls into the mixing chamber 202 by gravity. At this time, the second drive motor 204a starts, driving the rotating shaft 204b to rotate the first stirring blade 204c and the second stirring blade 204e. The through hole 204d of the first stirring blade 204c cuts the material flow to form a dispersed turbulent flow, and the second stirring blade 204e strongly stirs the material at the bottom. The two work together to make the material circulate and mix in the mixing chamber 202. After mixing is completed, the first drive motor 107d drives the lead screw 107e to rotate, driving the connecting arm 107f sleeved on its surface to slide along the sleeve 107c, so that the baffle plate 107g opens the drain outlet 107b of the discharge chute 107a. The material is guided and accelerated by the trapezoidal block 106 and discharged through the discharge chute 107a. The fixed connection between the trapezoidal block 106 and the discharge chute 107a enhances the structural stability and prevents material residue.

[0036] In summary, in the stirring assembly 204, the second drive motor 204a drives the rotating shaft 204b, causing turbulence to form in the through hole 204d of the first stirring blade 204c, which, together with the second stirring blade 204e, achieves three-dimensional mixing and ensures uniform doping. The trapezoidal block 106 of the main structure 100 guides the material to the discharge chute 107a, and the first drive motor 107d drives the lead screw 107e, which causes the connecting arm 107f to drive the baffle plate 107g to precisely control the drain outlet 107b, which not only helps with material discharge but also prevents excessive moisture. The fixed groove 105 and the limiting groove 203 enhance stability, reduce residue, and ensure efficient production of high-energy-density anode materials.
