Description

Technical Field

[0001] This utility model relates to the field of airflow pulverizer technology, specifically to an airflow pulverizer for preparing graphene materials. Background Technology

[0002] Graphene is a two-dimensional carbon nanomaterial composed of a single layer of carbon atoms arranged in a hexagonal honeycomb lattice with sp² hybrid orbitals. Its thickness is only 0.335 nanometers (about one two hundred thousandth of the diameter of a human hair), making it one of the thinnest, strongest, and most electrically and thermally conductive materials known to date.

[0003] Air jet mills are required in the process of pulverizing graphene materials. Existing air jet mills rely on high-speed airflow to drive the graphene material to flow at high speed inside the mill, and achieve the purpose of pulverization through collisions between materials and between the material and the mill.

[0004] However, when existing air jet mills pulverize graphene materials, the pulverized graphene material is scattered outward through the feed hopper, causing environmental pollution in the processing workshop and posing a certain risk to the health and safety of users. To address this issue, an air jet milling device for graphene material preparation is provided. Utility Model Content

[0005] The purpose of this utility model is to provide an airflow pulverizing device for graphene material preparation, so as to solve the problems mentioned in the background art. To achieve the above objective, this utility model provides the following technical solution: an airflow pulverizing device for graphene material preparation, including a support frame, a housing fixedly inserted into the middle of the support frame, a feeding hopper provided at the top of the housing, multiple fans arranged around the outer circumference of the housing, each fan having a conveying pipe at its output end, the other end of the conveying pipe extending into the inner cavity of the housing, multiple pulverizing blades arranged in the inner cavity of the housing, a pulverizing assembly provided at the top of the housing, two limiting strips slidably inserted into the top of the feeding hopper, the limiting strips being "T"-shaped, a sealing plate fixedly provided at the top of each of the two limiting strips, a frame provided at the top of the housing, a sliding assembly provided in the inner cavity of the frame, the sliding assembly being fixedly connected to the two sealing plates.

[0006] Preferably, the sliding assembly includes a motor, a lead screw, and sliders. The motor is located at the left end of the frame, and the output end of the motor extends into the inner cavity of the frame. One end of the lead screw is rotatably connected to the right side of the inner cavity of the frame via a bearing, and the other end of the lead screw is fixedly connected to the output end of the motor. The threads on the left and right sides of the outer wall of the lead screw are arranged opposite to each other. The two sliders are respectively screwed onto the left and right sides of the outer wall of the lead screw, and the two sliders are respectively fixedly connected to two sealing plates.

[0007] Preferably, a limiting groove is formed at the top of the housing, and two limiting blocks are slidably embedded in the inner cavity of the limiting groove. The two limiting blocks are respectively fixedly connected to the bottom ends of the two sliders.

[0008] Preferably, the inner cavity of the limiting groove and the outer wall of the limiting block are adapted to each other and are both in the shape of a "T".

[0009] Preferably, the bottom end of the bracket is provided with a plurality of support rods, the bottom end of each of the plurality of support rods is provided with a fixing plate, the bottom end of the fixing plate is provided with a telescopic rod, the bottom end of the telescopic rod is provided with a wheel, the outer wall of the telescopic rod is sleeved with a spring, the two ends of the spring are respectively fixedly connected to the fixing plate and the wheel, the bottom end of the fixing plate is provided with a fixing rod, and the bottom end of the fixing rod is provided with a support plate.

[0010] Preferably, the bottom end of the support plate is provided with an anti-slip ridge.

[0011] Preferably, the crushing component includes a motor and blades, the motor is located at the top of the housing, the output end of the motor extends into the inner cavity of the housing, and multiple blades are located at the output end of the motor.

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

[0013] 1. Start the fan to deliver high-speed air through the conveying pipe to the inner cavity of the machine casing. The high-speed air drives the graphene material to flow at high speed in the inner cavity of the machine casing, colliding with each other or with the crushing discs to crush the graphene material. Start the motor to drive the blades to rotate, which can further improve the crushing effect of the graphene material.

[0014] 2. Start the motor to drive the lead screw to rotate. Due to the opposing threads on the left and right sides of the lead screw's outer wall, a relative thread rotational force is generated, causing the two sliders to slide simultaneously towards the middle of the lead screw under the limiting action of the limiting groove and the limiting block. This causes the two sliders to drive the two sealing plates to slide simultaneously towards the top center of the feeding hopper under the limiting action of the limiting strip. The two sealing plates seal the top of the feeding hopper, thus preventing graphene material powder from floating out of the feeding hopper during the crushing process. This solves the problem in existing airflow pulverizers where the crushed graphene material floats out of the pulverizer's feeding hopper, causing environmental pollution in the processing workshop and posing a certain degree of harm to the user's health.

[0015] 3. After adding graphene material into the inner cavity of the housing, the spring can be compressed under the action of gravity, which in turn causes the wheel to shorten the distance between itself and the fixed plate in a straight line under the limiting action of the telescopic rod, so that the bottom end of the support plate contacts the ground, thereby increasing the friction between the device and the ground and preventing the device from moving during use.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1 to 4This utility model provides a technical solution: an airflow pulverizing device for graphene material preparation, including a support 1, a housing 2 fixedly inserted into the middle of the support 1, a feeding hopper 8 at the top of the housing 2, multiple fans 3 arranged around the outer circumference of the housing 2, each fan 3 having a conveying pipe 4 at its output end, the other end of the conveying pipe 4 extending into the inner cavity of the housing 2, multiple pulverizing blades 5 arranged in the inner cavity of the housing 2, a pulverizing assembly at the top of the housing 2, two limiting strips 9 slidably inserted into the top of the feeding hopper 8, the limiting strips 9 being "T"-shaped, each limiting strip 9 having a sealing plate 10 at its top, a frame 11 fixedly arranged at the top of the housing 2, a sliding assembly arranged in the inner cavity of the frame 11, the sliding assembly being fixedly connected to the two sealing plates 10. The blower 3 delivers high-speed air through the conveying pipe 4 to the inner cavity of the casing 2. The high-speed air causes the graphene material to flow at high speed within the casing 2, colliding with each other or with the crushing disc 5 to crush the graphene material. The sliding component drives the two sealing plates 10 to slide simultaneously towards the top center of the feeding hopper 8 under the limiting action of the limiting strip 9, so that the two sealing plates 10 seal the top of the feeding hopper 8. This prevents the graphene material powder from floating out through the feeding hopper 8 during the crushing process. This solves the problem in the existing airflow pulverizers where the crushed graphene material floats out through the feeding hopper 8, causing environmental pollution in the processing workshop and posing a certain degree of harm to the user's health.

[0023] In this embodiment, the sliding assembly includes a motor 12, a lead screw 13, and sliders 14. The motor 12 is located at the left end of the frame 11, and its output end extends into the inner cavity of the frame 11. One end of the lead screw 13 is rotatably connected to the right side of the inner cavity of the frame 11 via a bearing, and the other end of the lead screw 13 is fixedly connected to the output end of the motor 12. The threads on the left and right sides of the outer wall of the lead screw 13 are arranged opposite to each other. Two sliders 14 are respectively screwed onto the left and right sides of the outer wall of the lead screw 13. The two sliders 14 are respectively fixedly connected to the two sealing plates 10 through rods passing through the sliders 14. When the motor 12 is started, it drives the lead screw 13 to rotate. Due to the opposite threads on the left and right sides of the outer wall of the lead screw 13, relative rotation occurs. The rotational force of the screw thread causes the two sliders 14 to slide simultaneously toward the middle of the lead screw 13 under the limiting action of the limiting groove 15 and the limiting block 16. This causes the two sliders 14 to drive the two sealing plates 10 to slide simultaneously toward the middle of the top of the feeding hopper 8 under the limiting action of the limiting strip 9. This seals the top of the feeding hopper 8 with the two sealing plates 10, preventing graphene material powder from floating out through the feeding hopper 8 during the crushing process. This solves the problem in the existing airflow pulverizers where the crushed graphene material floats out through the feeding hopper 8, causing environmental pollution in the processing workshop and posing a certain risk to the user's health.

[0024] In this embodiment, a limiting groove 15 is provided at the top of the housing 2. Two limiting blocks 16 are slidably embedded in the inner cavity of the limiting groove 15. The two limiting blocks 16 are fixedly connected to the bottom ends of the two sliders 14 respectively. Under the joint action of the limiting groove 15 and the limiting blocks 16, the sliders 14 can be prevented from rotating with the lead screw 13 when the lead screw 13 rotates, thereby improving the stability of the sliding assembly during use.

[0025] In this embodiment, the inner cavity of the limiting groove 15 and the outer wall of the limiting block 16 are adapted to each other and are both in the shape of a "T". This allows one end of the limiting block 16 to always remain embedded in the inner cavity of the limiting groove 15, thereby improving the stability of the limiting component during use.

[0026] In this embodiment, the bottom end of the bracket 1 is provided with multiple support rods 17, and the bottom end of each support rod 17 is provided with a fixing plate 18. The bottom end of the fixing plate 18 is provided with a telescopic rod 19, and the bottom end of the telescopic rod 19 is provided with a wheel 20. A spring 21 is sleeved on the outer wall of the telescopic rod 19. The two ends of the spring 21 are fixedly connected to the fixing plate 18 and the wheel 20, respectively. The bottom end of the fixing plate 18 is provided with a fixing rod 22, and the bottom end of the fixing rod 22 is provided with a support plate 23. After the graphene material is added to the inner cavity of the housing 2, the spring 21 can be compressed under the action of gravity, thereby causing the wheel 20 to shorten the distance between itself and the fixing plate 18 in a straight line under the limiting action of the telescopic rod 19, so that the bottom end of the support plate 23 contacts the ground, thereby increasing the friction between the device and the ground and preventing the device from moving during use.

[0027] In this embodiment, the bottom end of the support plate 23 is provided with anti-slip ridges, which improves the roughness of the bottom end of the support plate 23 and thus increases the friction when the support plate 23 contacts the ground.

[0028] In this embodiment, the pulverizing component includes a motor 6 and blades 7. The motor 6 is located at the top of the housing 2, and the output end of the motor 6 extends into the inner cavity of the housing 2. Multiple blades 7 are located at the output end of the motor 6. When the motor 6 is started, it drives the blades 7 to rotate, thereby further improving the pulverizing effect of graphene materials.
