Description

Technical Field

[0001] The utility model relates to the technical field of processing of massive hard carbon anode materials, and particularly relates to a spheroidizing treatment device for massive hard carbon anode materials. Background Technique

[0002] Due to the advantages of good electrical conductivity, high sodium storage capacity, low volume expansion during sodium insertion, environmental friendliness, and low redox potential of massive hard carbon anode materials, they are widely used in new energy vehicles, energy storage fields, etc. During the production and processing of massive hard carbon anode materials, spheroidizing treatment is often required. However, there are still some problems when using the spheroidizing treatment device for massive hard carbon anode materials.

[0003] For example, a spheroidizing treatment device for massive hard carbon anode materials disclosed in the patent application No. 202120200833.8 includes a box body. There is a feeding port opened on the left side of the top of the box body. A dust collector is installed on the lower right side of the box body through screws. One end of a dust suction pipe is installed on the top of the dust collector through screws. A button is installed on the right side of the front of the box body through screws. A placement groove is opened on the right side inside the box body. A baffle is installed in front of the placement groove through a bolt. A slide rail is installed on the top of the inner wall of the box body through screws. A motor is installed on the right side of the top of the slide rail through screws. A controller is arranged on the right side of the motor. The controller is installed on the slide rail through screws. A sensor is installed on the right end of the slide rail through screws. A slider is arranged below the slide rail. A grinding table a is installed at the bottom of the slider through screws. This spheroidizing treatment device for massive hard carbon anode materials has the advantages of equipment automation, rapid grinding, and carbon powder collection. However, it is still difficult to perform comprehensive spherical grinding treatment on the products of massive hard carbon anode materials, which results in low spheroidizing processing accuracy and poor processing effect of the products. Moreover, it is also difficult to synchronously clamp and position the spheroidizing products of massive hard carbon anode materials to be processed, which will affect the processing effect of the products and is prone to processing errors. Based on this, we propose a new type of spheroidizing treatment device for massive hard carbon anode materials. Content of the Utility Model

[0012] Compared with the prior art, the beneficial effects of the present utility model are:

[0013] (1). The spheroidizing treatment device for the block-shaped hard carbon negative electrode material optimizes its own structure by installing a first motor, etc. When the first motor starts, it drives the solid gear to rotate, and then drives the hollow gear meshing with the solid gear to rotate, thereby driving the rotation of the spheroidizing grinding die installed on the hollow gear. At the same time, two electric slide rails start and drive the hollow drive seat to move automatically towards the direction of the spheroidizing grinding die. Furthermore, through the relative close movement and rotational movement between the spheroidizing grinding die in a hemispherical shape and the block-shaped hard carbon negative electrode material product clamped between the two positioning and clamping arms, the spheroidizing processing of one side of the block-shaped hard carbon negative electrode material product can be achieved. Subsequently, the side of the block-shaped hard carbon negative electrode material that has not been ground into a spherical shape is fixed between the two positioning and clamping arms facing the hemispherical spheroidizing grinding die, which can achieve the spheroidizing treatment of the other side of the product. Thus, the device can achieve high-precision spheroidizing processing of the block-shaped hard carbon negative electrode material product and improve the forming quality;

[0014] (2). The spheroidizing treatment device for the block-shaped hard carbon negative electrode material optimizes its own performance by installing a transmission lead screw, etc. When the second motor starts, it can drive the transmission lead screw to rotate, which can drive two transmission nut seats threaded on the transmission lead screw to move. And based on the outer side wall of the transmission lead screw above and below the separator, there are external thread layers with opposite directions, and the inside of the transmission nut seat is provided with internal thread layers matching the external thread layers, which can drive the two transmission nut seats to move closer to or away from each other, thereby changing the distance between the positioning and clamping arms fixed on the two transmission nut seats and achieving the clamping and fixing of block-shaped hard carbon negative electrode materials of different specifications. And through the synchronous movement of the two positioning and clamping arms, it can also ensure that the two are always symmetrically distributed about the separator at all times, thereby ensuring the positioning of the block-shaped hard carbon negative electrode material product clamped by the two positioning and clamping arms. This enables the device to simultaneously achieve automatic clamping and automatic positioning of the block-shaped hard carbon negative electrode material;

[0015] (3). The spheroidizing treatment device for the block-shaped hard carbon negative electrode material optimizes its own performance by installing a waste collection box, etc. During actual operation of the device, when the dust removal fan is started, the gas inside the waste collection box can be pumped out, which can create a negative pressure attraction inside the waste collection box and the flexible hose. Then, through the hollow rotatable joint and the hollow gear, the carbon powder and other waste materials generated when the spheroidizing grinding die connected to the hollow gear grinds the block-shaped hard carbon negative electrode material product can be pumped into the waste collection box for collection. This facilitates the collection and reuse of carbon powder waste and realizes the advantages of energy conservation and environmental protection. Brief Description of the Drawings
