Description

Technical Field

[0001] This utility model relates to the field of graphite powder processing technology, and in particular to a horizontal single-rotor graphite powder shaping device. Background Technology

[0002] With the increasing demand for graphite materials across various industries, especially in the lithium battery field, natural graphite needs to be shaped into spherical or near-spherical forms to improve its cycle stability and tap density; artificial graphite also needs to be shaped to improve its electrochemical behavior. Traditional graphite preparation processes suffer from low productivity, high energy consumption, high cost, and unsatisfactory product performance.

[0003] To address the above issues, a Chinese utility model patent (publication number CN220969316U), entitled "A Spheroidizing and Shaping Equipment for Natural Flake Graphite," with our company as the patentee, discloses a triangular-shaped three-rotor spheroidizing and shaping machine. This machine significantly improves the tap density of graphite and effectively controls the rapid increase in its specific surface area. However, this equipment has a relatively complex structure and, for graphite products with less stringent shaping requirements, suffers from drawbacks such as large size, high manufacturing cost, high power consumption, and difficult maintenance.

[0004] Therefore, in order to meet the shaping needs of different product models, reduce energy consumption and equipment manufacturing costs, and improve shaping efficiency, designing a horizontal single-rotor graphite powder shaping device has become a technical problem that urgently needs to be solved by those skilled in the art.

[0005] The technical problem to be solved by this utility model is to provide a horizontal single-rotor graphite powder shaping equipment that addresses the above-mentioned shortcomings. It has the advantages of simple structure, small size, good shaping effect, convenient maintenance, and low energy consumption.

[0006] To solve the above problems, the technical solution adopted by this utility model is as follows:

[0007] A horizontal single-rotor graphite powder shaping device includes a housing, within which a horizontally and rotatably mounted rotor is disposed. The rotor includes a hammerhead disc and a plurality of shaping hammers detachably mounted on the periphery of the hammerhead disc at intervals. The shaping hammers are arranged radially along the hammerhead disc. Each shaping hammer is T-shaped and includes a hammer seat, a conical shank, and a hammer head connected in sequence. The hammer seat is mounted on the hammerhead disc. Both the conical shank and the hammer head are cylindrical structures. A plurality of shaping rods are fixed on the housing and arranged radially thereafter. The plurality of shaping rods are spaced apart from the plurality of shaping hammers.

[0008] As an improvement, the hammerhead disc includes a horizontally arranged body and multiple discs spaced apart on the body; multiple shaping hammers are respectively installed between two adjacent discs.

[0009] As an improvement, a pad is provided between the hammer base and the disc body, and the hammer base is mounted on the disc body by a pin, allowing the hammer base to rotate relative to the pin.

[0010] As an improvement, a liner is installed on the inner wall of the housing. The liner includes two spaced-apart, annular end plates, and multiple cylindrical screen bars are connected between the two end plates.

[0011] As an improvement, the liner plate is provided with a clearance area corresponding to the position of the shaped round bar.

[0012] As an improvement, the housing is provided with multiple mounting parts for mounting the shaping round bar. The outer end of the shaping round bar is T-shaped. The mounting part is provided with a through third mounting hole that matches the T-shaped end of the shaping round bar. The T-shaped end of the shaping round bar is fixedly installed in the third mounting hole.

[0013] As an improvement, the housing has an opening at one end, on which a removable end cover is installed, and a removable maintenance cover is provided in the middle of the end cover.

[0014] As an improvement, it also includes a rotating main shaft located on the side of the housing; one end of the main shaft extends into the interior of the housing, the rotor is fixedly mounted on the main shaft, and the other end of the main shaft is connected to the motor drive via a coupling.

[0018] (1) This utility model is a horizontal single-rotor graphite powder shaping equipment. It adopts a single rotor method and a horizontal structure with the main shaft installed horizontally. One shaping machine has only one rotor, which is different from the existing three-rotor triangular structure.

[0031] For ease of explanation rather than limitation, the side of the horizontal single-rotor graphite powder shaping equipment closest to the center of the shaping chamber is defined as the inner side, and the opposite side is defined as the outer side.

[0032] Example

[0033] like Figures 1 to 9As shown, a horizontal single-rotor graphite powder shaping device includes a base 20 and a motor 18, a bearing sleeve 21, and a housing 1, which are sequentially fixedly mounted on the base 20. The housing 1 is cylindrical, and a cylindrical shaping chamber is formed inside the housing 1. A horizontally rotatable rotor 2 is provided inside the housing 1, and the rotor 2 can rotate horizontally along its central axis. A rotatable main shaft 17 is provided on the side of the housing 1, and the main shaft 17 is rotatably mounted on the bearing sleeve 21. One end of the main shaft 17 extends into the interior of the housing 1, and the rotor 2 is fixedly mounted on the main shaft 17; the other end of the main shaft 17 is connected to the motor 18 through a coupling 19. When the motor 18 rotates, it drives the rotor 2 to rotate inside the housing 1 through the coupling 19 and the motor 18.

[0034] The upper part of the casing 1 is provided with a feed inlet 22 and a discharge outlet 23 spaced apart, located on opposite sides above the rotor 2. The casing 1 is provided with a coolant jacket 24, and at least two interfaces 25 communicating with the coolant jacket 24. In this embodiment, coolant is preferably used. During use, the two interfaces 25 are connected to the inlet pipe and the outlet pipe, respectively, allowing the coolant to flow within the coolant jacket 24 and carry away the heat generated during the graphite powder shaping process.

[0035] like Figures 1 to 9 As shown, the rotor 2 includes a hammerhead disc 3 and multiple detachably mounted shaping hammers 4 spaced apart around the hammerhead disc 3. The shaping hammers 4 are T-shaped and include a hammer base 5, a conical shank 6, and a hammer head 7 connected in sequence. The hammer base 5 is fixedly or rotatably mounted on the hammerhead disc 3. Both the conical shank 6 and the hammer head 7 are cylindrical structures, meaning the portion of the shaping hammer 4 protruding from the hammerhead disc 3 has a cylindrical cross-section. This design prevents over-grinding of the graphite powder during shaping, facilitating the shaping of the graphite powder and improving shaping efficiency and quality. Multiple shaping rods 8 are fixed on the housing 1, arranged radially. These shaping rods 8 are spaced apart from the multiple shaping hammers 4.

[0036] like Figures 1 to 5 , Figure 8 and Figure 9As shown, the hammerhead disc 3 includes a horizontally arranged body 9 and multiple discs 10 spaced apart on the body 9. A horizontally penetrating second mounting hole 31 is provided in the middle of the body 9. The second mounting hole 31 is adapted to the size of the main shaft 17, and the end of the main shaft 17 is fixedly installed in the second mounting hole 31 of the body 9. Multiple shaping hammers 4 are respectively fixedly installed or rotatably installed between two adjacent discs 10. A pad 13 is provided between the hammer seat 5 and the disc 10, and the hammer seat 5 is fixedly installed on the disc 10 by a pin 12. Weight reduction holes 30 are provided on the disc 10. Specifically, the disc 10 has multiple sets of first mounting holes 11; the hammer seat 5 and the pad 13 are each provided with corresponding first mounting holes 11, and the pin 12 passes through multiple discs 10, hammer seats 5, and pads 13. In this embodiment, the example is that the main body 9 has seven discs 10, and twenty evenly distributed shaping hammers 4 are installed between each pair of adjacent discs 10. The twenty shaping hammers 4 installed between each pair of adjacent discs 10 form a group, resulting in six groups of shaping hammers 4, for a total of one hundred and twenty shaping hammers 4. In practical applications, the number of discs 10 and the number of shaping hammers 4 installed between each pair of adjacent discs 10 can be adjusted according to requirements. In this embodiment, the pad 13 is preferably annular.

[0037] Multiple shaping hammers 4 are fixedly or rotatably mounted between two adjacent discs 10. If a hammer base 5 is fixedly mounted on the hammer head disc 3, the shaping hammers 4 are arranged radially along the hammer head disc 3. Preferably, in this embodiment, the shaping hammers 4 are rotatably mounted between two adjacent discs 10. The hammer base 5 can rotate relative to the pin 12, and a clearance fit is used between the hammer base 5 and the pin 12. When the rotor 2 rotates, the shaping hammers 4 are radially arranged along the circumference of the rotor 2 due to the centrifugal force. The advantage of this structural design is that when the horizontal single-rotor graphite powder shaping equipment is loaded with material to be shaped, multiple rotors are not simultaneously subjected to force but are gradually subjected to force during equipment startup, resulting in low instantaneous resistance during startup and facilitating equipment startup.

[0038] like Figure 1 and Figure 2 As shown, multiple shaping rods 8 are provided along the axial direction of the housing 1 and in the gap between two adjacent shaping hammers 4. Each pair of shaping rods 8 in each gap is a group, so there are a total of five groups of shaping rods 8.

[0039] like Figure 1 , Figure 2 and Figure 6As shown, the housing 1 is provided with multiple mounting portions 26 for mounting the shaping round bar 8. The outer end of the shaping round bar 8 is T-shaped. The mounting portion 26 is provided with a through third mounting hole that matches the T-shaped end of the shaping round bar 8. The T-shaped end of the shaping round bar 8 is fixedly installed in the third mounting hole. In this embodiment, preferably, the end of the third mounting hole is machined with an internal thread. The shaping round bar 8 extends into the interior of the housing 1 from the outside through the third mounting hole and the T-shaped end of the shaping round bar 8 is placed in the third mounting hole. A cylindrical fixing block 27 is installed at the outer end of the third mounting hole. The fixing block 27 is machined with an external thread and is fixedly connected to the third mounting hole by the thread.

[0040] like Figures 1 to 9 As shown, a liner 14 is installed on the inner wall of the casing 1. The liner 14 includes two spaced-apart, annular end plates 15, with multiple cylindrical sieve ribs 16 connected between the two end plates 15. A clearance area is provided on the liner 14 corresponding to the position of the shaping rod 8. One end of the casing 1 is open, and a removable end cover 28 is installed on the opening. A removable maintenance cover 29 is provided in the middle of the end cover 28. The maintenance cover 29 corresponds to the position of the main shaft 17. After removing the end cover 28, the liner 14 and the rotor 2 can be easily removed from the casing 1, facilitating the maintenance and cleaning of this horizontal single-rotor graphite powder shaping equipment.

[0041] In use, the motor 18 is started, and the rotation of the motor 18 drives the rotor 2 to rotate inside the housing 1 through the coupling 19. Graphite powder is fed into the shaping chamber inside the housing 1 through the inlet 22 by airflow, and is output through the outlet 23. When the graphite powder passes through the shaping chamber, the rotor 2 inside the housing 1 rotates at high speed, causing the graphite powder to collide with the shaping hammer 4, or the shaping round bar 8, or the sieve ribs 16 on the liner 14, spheroidizing the natural flake graphite inside the housing 1 and enhancing the spheroidizing efficiency of the natural flake graphite.

[0042] In summary, this utility model discloses a horizontal single-rotor graphite powder shaping device, which adopts a single rotor and a horizontal structure with the main shaft installed horizontally. One shaping machine has only one rotor, which is different from the existing three-rotor triangular structure. It has the advantages of simple structure, low manufacturing cost, low failure rate, convenient maintenance, and low power consumption.

[0043] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
