Description

Technical Field

[0001] The utility model relates to the technical field of pickling of hard carbon materials, in particular to a pickling device for processing hard carbon materials. Background Art

[0002] Hard carbon refers to carbon that is difficult to graphitize. It is the thermal decomposition of high molecular polymers. Common hard carbons include resin carbon, organic polymer pyrolysis carbon and carbon black. Studies have found that hard carbon materials have very high reversible specific capacity. Low or non-graphitizable hard carbon is also the negative electrode material of power lithium-ion batteries. Hard carbon has a stable structure and a long charge and discharge cycle life, better safety performance, and can overcome the high activity of graphitized carbon when charged into lithium graphite. Once an internal short occurs, it will cause serious exothermic reverse conversion and create the risk of explosion. Hard carbon also has problems such as large change in discharge voltage with capacity and lower initial charge and discharge efficiency than graphitized carbon. Research on modification of hard carbon materials is one of the important ways to improve hard carbon as a negative electrode material for lithium-ion batteries.

[0003] For example, the patent document with the announcement number CN 217222679 U discloses a pickling device for processing hard carbon materials, including: a shell, a stirring tube, and a blower. The shell is fixed to the equipment frame, and a pickling tank is arranged inside the shell; the blower is installed on the left side of the shell, and the output end of the blower is fixedly connected to an air outlet pipe; the outlet direction of the air outlet pipe is the pickling tank, and the other end of the air outlet pipe is connected to a detachable hard carbon material tank; a sealing ring is arranged between the hard carbon material tank and the air outlet pipe; at least one set of pressing rollers is arranged in the pickling tank, and a number of spaced protrusions are arranged on the surface of the pressing rollers; a filter screen is fixed on the inner wall of the pickling tank, and a sleeve is fixedly connected to the right side of the shell. The pickling equipment of the present application is adopted, and the combination of the blower, the air outlet pipe and the hard carbon material tank is used to realize the complete injection of the hard carbon material into the pickling tank, which can effectively prevent leakage and environmental pollution. The pressing roller is arranged in the pickling tank, and the hard carbon material can be initially crushed for pickling treatment.

[0004] However, in the actual process of pickling hard carbon materials, this structure can only complete the treatment of hard carbon materials by direct immersion. However, this will result in the pickling raw materials being unable to be fully mixed with the hard carbon materials, resulting in poor actual pickling effects. At the same time, when the equipment subsequently adds pickling materials, it is unable to quickly contact and react with the hard carbon materials, resulting in incomplete pickling and being unable to meet daily use needs. Therefore, it is urgent to design a pickling equipment for treating hard carbon materials to solve the above problems. Summary of the invention

[0005] The purpose of the utility model is to provide a pickling device for treating hard carbon materials, so as to solve the problem that the existing structure proposed in the above background technology can only complete the treatment of hard carbon materials by direct immersion during the actual pickling process of hard carbon materials, but this will result in the pickling raw materials being unable to be fully mixed with the hard carbon materials, resulting in poor actual pickling effect. At the same time, when the pickling materials are added later, the equipment cannot quickly contact and react with the hard carbon materials, resulting in incomplete pickling and being unable to meet daily use needs.

[0006] To achieve the above object, the utility model provides the following technical solution: a pickling device for processing hard carbon materials, comprising a sleeve frame, a rotating groove is provided inside the sleeve frame, a pickling tank is movably connected inside the rotating groove, and a discharge valve pipe is provided on the back of the sleeve frame;

[0007] A mounting seat, wherein the bottom end of the sleeve frame is provided with a mounting seat, and the bottom of the sleeve frame is fixedly connected with a supporting seat;

[0008] A stirring rack is provided on the inner top wall of the sleeve frame.

[0009] Preferably, a main rotating roller is arranged at the bottom center of the mixing frame, and a material mixing seat is opened at the surface center of the mixing frame.

[0010] Preferably, bearing seats are evenly arranged on the four sides of the stirring frame, and auxiliary rollers are evenly arranged on the four sides of the bottom of the stirring frame through the bearing seats.

[0011] Preferably, a transmission frame is arranged at the bottom end of the sleeve frame, and a first driving motor is arranged at the bottom of the transmission frame.

[0012] Preferably, a mounting groove is provided inside the mounting seat, and a second driving motor is arranged at the inner center of the mounting groove.

[0013] Preferably, the inner wall of the rotating groove is provided with a damping rubber sleeve, and the inner wall of the pickling tank is provided with an anti-stick coating.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] The pickling equipment for processing hard carbon materials can achieve efficient and sufficient mixing and pickling operation of the hard carbon materials in the pickling tank through the arrangement of the sleeve frame, rotating groove, pickling tank, mounting seat, stirring frame, main roller, bearing seat, auxiliary roller, transmission frame, first drive motor, second drive motor and damping rubber sleeve. In actual use, the staff first puts the hard carbon material to be pickled into the pickling tank, and then fills the pickling tank with pickling liquid. At this time, the first drive motor at the bottom of the transmission frame is started first, and the main roller and all auxiliary rollers at the bottom of the stirring frame are driven by the transmission frame to rotate rapidly, and the hard carbon material is initially stirred in the pickling tank. Then, the second drive motor in the mounting seat is started to drive the transmission frame, the first drive motor and the pickling tank as a whole to rotate in the rotating groove of the sleeve frame, so that the hard carbon material and the pickling liquid are more fully stirred, which assists in quickly completing the sufficient pickling work, and reflects the practicality of the equipment design.

[0016] The pickling equipment for processing hard carbon materials further improves the overall use effect of the equipment by arranging a sleeve frame, a stirring frame, a main roller, a material mixing seat, a bearing seat, an auxiliary roller, a transmission frame and a first drive motor. In daily use, when the main roller and the auxiliary roller at the bottom of the stirring frame and the sleeve frame are synchronously rotated in the pickling tank inside the rotating trough to mix the hard carbon material and the pickling liquid, the external pipe can be connected to the material mixing seat at the center of the surface of the stirring frame in an axial connection manner. The material mixing seat is first connected to the inside of the main roller and all the auxiliary rollers through the stirring frame. At this time, the pickling material can be quickly and evenly mixed and contacted with the hard carbon material through the main roller and the auxiliary roller by pressurization, which greatly improves the overall pickling effect of the equipment and reflects the comprehensiveness of the equipment design.
