Description

Technical Field

[0001] This utility model belongs to the technical field of graphene production equipment, specifically a filtration device for graphene production. Background Technology

[0002] Graphene is a novel material with a single-layer two-dimensional honeycomb lattice structure in which carbon atoms are closely packed together in an sp2 hybrid configuration, and it has been widely used in many fields.

[0003] The graphene production process requires the use of filtration devices to filter impurities from the graphene powder.

[0004] Existing graphene-based filtration devices have the following drawbacks:

[0005] (1) Graphene powder is usually filtered by vibrating the filter screen through a vibrating motor to separate graphene from impurities. However, since the filter screen is usually detachably connected to the filter screen frame by bolts, the disassembly and installation of the filter screen is relatively troublesome and requires the use of external tools, making it inconvenient to use.

[0006] (2) The feed inlet is usually not equipped with a material control device, which can easily lead to powder accumulation and affect the filtration effect when filtering graphene. Summary of the Invention

[0007] The purpose of this invention is to provide a filtration device for graphene production, which facilitates quick installation and disassembly of the filter screen, prevents graphene powder from flying away, and allows control of the graphene feeding speed, thereby improving the filtration effect.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a filtration device for graphene production, comprising a housing and a discharge pipe connected to the lower end of the housing. Mounting plates are fixedly connected to both ends of the housing. Electric actuators are mounted on the lower ends of both mounting plates. The output ends of the two electric actuators pass through the mounting plates and are fixedly connected to a cover plate. A mounting ring is fixedly connected to the lower end face of the cover plate. Multiple evenly distributed ball bearings are embedded in the lower end face of the mounting ring. A bracket is fixedly connected to the bottom inner end face of the housing. A motor is mounted on the top inner end face of the bracket. The output end of the motor passes through the bracket and is fixedly connected to a mounting rod. A sleeve is fitted onto the outer wall of the mounting rod. A filter cartridge is mounted on the upper end face of the sleeve. An annular groove is formed on the upper end face of the filter cartridge, allowing it to circulate with the multiple ball bearings.

[0009] A material control device is provided above the cover plate.

[0010] To prevent graphene from accumulating inside the filter cartridge, a preferred filtration device for graphene production according to this invention includes a discharge cylinder that penetrates and is fixedly installed on the upper end of a cover plate. The upper end of the discharge cylinder is connected to a storage tank. A second motor is installed on the front end of the discharge cylinder. The output end of the second motor penetrates the discharge cylinder and is fixedly connected to a guide turntable. Two symmetrically distributed baffles that abut against the outer wall of the guide turntable are fixedly connected to the inner wall of the discharge cylinder. Multiple diversion plates are fixedly connected between the front and rear side walls inside the discharge cylinder.

[0011] To facilitate the insertion of the sleeve into the interior of the mounting rod, in a preferred embodiment of the filtration device for graphene production according to this utility model, the mounting rod is arranged in a "+" shape, and the inner wall of the sleeve is adapted to the shape of the mounting rod.

[0012] To protect the motor, as a preferred embodiment of the filtration device for graphene production according to this utility model, a protective shell fitted onto the outer wall of the motor is installed at the top of the inner side of the bracket.

[0013] To prevent powder from flying, as a preferred embodiment of the filtration device for graphene production according to this utility model, the upper end of the storage tank is threadedly connected with a threaded cap.

[0014] In order to control the operation of each component, as a preferred embodiment of the filtration device for graphene production according to this utility model, a control panel is installed on the front end of the storage tank.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This utility model uses two electric push rods to drive the cover plate to move upward, inserting the sleeve at the lower end of the filter cartridge into the installation rod. The two electric push rods are then driven in the opposite direction to move the cover plate in the opposite direction, causing multiple balls embedded at the lower end of the installation ring to abut against the inner wall of the annular groove at the upper end of the filter cartridge, thus facilitating the installation of the filter cartridge.

[0017] The graphene powder to be filtered is introduced into the filter cartridge in batches through the material control mechanism. At the same time, the motor is started, and the output end of the motor drives the mounting rod to rotate, thereby driving the sleeve and the filter cartridge to rotate, thus screening and filtering the graphene. The batch feeding through the material control device can prevent the graphene from accumulating inside the filter cartridge, thereby improving the filtration effect.

[0018] When the filter cartridge needs to be disassembled, the cover plate is moved upward by two electric push rods to open the upper port of the housing. Then, the sleeve at the lower end of the filter cartridge is disengaged from the mounting rod, and the filter cartridge can be taken out from the inside of the housing, which makes it easy to disassemble the filter cartridge.

The output ends of the two electric push rods 4 pass through the mounting plates 3 and are fixedly connected to a cover plate 2. A mounting ring 6 is fixedly connected to the lower end face of the cover plate 2. Multiple evenly distributed rolling balls 7 are embedded in the lower end face of the mounting ring 6. A bracket 11 is fixedly connected to the bottom end face of the inside of the housing 1. A motor 12 is installed on the top end face inside the bracket 11.

A filter cartridge 5 is installed on the upper end face of the sleeve 19. An annular groove 8 is opened on the upper end face of the filter cartridge 5 to roll and connect with the multiple rolling balls 7.

[0026] A material control device is installed above the cover plate 2.

[0027] In this embodiment: When in use, start the two electric push rods 4 to drive the cover plate 2 to move upward, open the upper port of the box 1, and then insert the sleeve 19 at the lower end of the filter cartridge 5 into the installation rod 13. Drive the two electric push rods 4 in the opposite direction to make the cover plate 2 move in the opposite direction, so that the multiple balls 7 embedded at the lower end of the installation ring 6 abut against the inner wall of the annular groove 8 at the upper end of the filter cartridge 5.

[0028] The graphene powder to be filtered is introduced into the filter cartridge 5 in batches through the material control mechanism. At the same time, the motor 12 is started. The output end of the motor 12 drives the mounting rod 13 to rotate, thereby driving the sleeve 19 and the filter cartridge 5 to rotate, thus screening and filtering the graphene. The batch feeding through the material control device can prevent the graphene from accumulating inside the filter cartridge 5, thereby improving the filtration effect.

[0029] When the filter cartridge 5 needs to be disassembled, activate the two electric actuators 4 to drive the cover plate 2 to move upward, open the upper port of the housing 1, and then disengage the sleeve 19 at the lower end of the filter cartridge 5 from the mounting rod 13. The filter cartridge 5 can then be removed from the inside of the housing 1. The operation is simple and convenient. In addition, the cover plate 2 can close the upper port of the housing 1 to prevent powder from flying.

[0030] As a technical optimization of this utility model, the material control device includes a discharge cylinder 9 that passes through and is fixedly installed on the upper end face of the cover plate 2. The upper end of the discharge cylinder 9 is connected to a storage tank 17. A second motor 20 is installed on the front end face of the discharge cylinder 9. The output end of the second motor 20 passes through the discharge cylinder 9 and is fixedly connected to a guide turntable 15. Two symmetrically distributed baffles 16 are fixedly connected to the inner wall of the discharge cylinder 9 and abut against the outer wall of the guide turntable 15. Multiple diversion plates 10 are fixedly connected between the front and rear side walls inside the discharge cylinder 9.

[0031] In this embodiment: the second motor 20 is used to drive the guide turntable 15 to rotate. Through the cooperation of the guide turntable 15 and the baffle 16, graphene can be introduced into the box 1 in batches, and the powder can be dispersed into the filter cartridge 5 with the help of the diversion plate 10, thereby preventing graphene from accumulating inside the filter cartridge 5.

[0032] As a technical optimization of this utility model, the mounting rod 13 is set in a "+" shape, and the inner wall of the sleeve 19 is adapted to the shape of the mounting rod 13.

[0033] In this embodiment, the inner wall of the sleeve 19 is adapted to the shape of the mounting rod 13, so that the sleeve 19 can be easily inserted into the interior of the mounting rod 13.

[0034] As a technical optimization of this utility model, a protective shell that is sleeved on the outer wall of the motor 12 is installed at the top inside the bracket 11.

[0035] In this embodiment: the protective shell is used to protect the motor 12.

[0036] As a technical optimization of this utility model, the upper end of the storage tank 17 is threadedly connected to a threaded cover 18.

[0037] In this embodiment, the upper end of the storage tank 17 can be sealed by the threaded cap 18 to prevent powder from flying.

[0038] As a technical optimization of this utility model, a control panel is installed on the front end face of the storage tank 17.

[0039] In this embodiment, the control panel is electrically connected to the electric actuator 4, the motor 12, and the second motor 20, and the electric actuator 4 and the motor 12 can be controlled by the control panel.

[0040] Working principle: When in use, start the two electric push rods 4 to drive the cover plate 2 to move upward, open the upper port of the box 1, and then insert the sleeve 19 at the lower end of the filter cartridge 5 into the installation rod 13. Drive the two electric push rods 4 in the opposite direction to make the cover plate 2 move in the opposite direction, so that the multiple balls 7 embedded at the lower end of the installation ring 6 abut against the inner wall of the annular groove 8 at the upper end of the filter cartridge 5.

[0041] The graphene powder to be filtered is added into the storage tank 17 and sealed with a threaded cap 18. The second motor 20 drives the guide turntable 15 to rotate intermittently at 90°. The guide turntable 15, in conjunction with the baffle 16, guides the graphene into the housing 1 in batches. The distribution plate 10 disperses the powder into the filter cartridge 5, preventing graphene from accumulating inside the filter cartridge 5. Simultaneously, the motor 12 is started, and its output drives the mounting rod 13 to rotate, thereby driving the sleeve 19 and the filter cartridge 5 to rotate, thus sieving and filtering the graphene. The batch feeding through the material control device prevents graphene from accumulating inside the filter cartridge 5, thereby improving the filtration effect.

[0042] When the filter cartridge 5 needs to be disassembled, activate the two electric actuators 4 to drive the cover plate 2 to move upward, open the upper port of the housing 1, and then disengage the sleeve 19 at the lower end of the filter cartridge 5 from the mounting rod 13. The filter cartridge 5 can then be removed from the inside of the housing 1. The operation is simple and convenient. In addition, the cover plate 2 can close the upper port of the housing 1 to prevent powder from flying.
