Description

Technical Field

[0001] The utility model relates to the technical field of graphene slurry preparation, in particular to a fine filtration device for graphene slurry preparation. Background Technique

[0002] Graphene is a new material with a single-layer two-dimensional honeycomb lattice structure formed by tightly packing carbon atoms connected by sp2 hybridization. Graphene has excellent optical, electrical and mechanical properties and has important application prospects in materials science, micro-nano processing, energy, biomedicine and drug delivery. It is considered a revolutionary material in the future. During the preparation of graphene slurry, a fine filtration device is needed to filter and screen out large particles doped in the graphene slurry;

[0003] The applicant found through retrieval that the Chinese patent discloses a "fine filtration device for graphene slurry preparation", and its publication (announcement) number is "CN 221673611 U". This patent mainly places the graphene slurry on the top of the first filter screen, starts the driving mechanism, drives the push rod to move left by the rotation of the turntable, and after the force plate is driven by the leftward thrust to drive the first filter screen to move left, the first filter screen is urged to move right back to the origin by the elastic force of the connecting spring, and at the same time drives the second filter screen to move, so as to reciprocate to make the graphene slurry on the top of the first filter screen be screened and fall into the top of the second filter screen. The graphene slurry after two filtrations finally flows into the material receiving box to complete collection, achieving the purpose of good filtration effect. However, the filter screen of this device is prone to local accumulation or stagnation, which is not conducive to the liquid passing through the flat membrane, and the graphene particles intercepted on the filter screen are not easy to clean. Therefore, we propose a fine filtration device for graphene slurry preparation. Content of the Utility Model

The top end of the feeding pipe 31 is rotatably connected to the inner core 321 provided at one end of the rotary joint 32, and a material baffle 311 is provided at the bottom end of the feeding pipe 31. The material guiding cover 33 is arranged directly below the material baffle 311. The material guiding cover 33 is a hollow cone. A plurality of discharge ports 331 are evenly spaced on the edge of the material guiding cover 33, and the edge of the material guiding cover 33 is detachably connected to the edge of the material baffle 311. The top end of the rotating shaft 34 is fixedly connected to the middle part of the inner cavity of the material guiding cover 33, and the bottom end of the rotating shaft 34 is detachably connected to the rear curved blade paddle 35;

[0030] The filtering component 4 is located directly below the backward-curved blade paddle 35. The filtering component 4 includes a circular frame 41, a support mesh 42, and a fixing hoop 43. The circular frame 41 is slidably mounted on the semi-circular through opening 11. The support mesh 42 is arranged on the top of the circular frame 41 and is used to support the flat membrane placed on its top. The fixing hoop 43 is used to fix the edge of the flat membrane to the side wall of the support mesh 42.

[0031] In an embodiment of the present utility model: The feed pipe 31 is in interference fit with the bearing provided in the middle of the tank cover 2, and the circular support plate 312 provided on the outer wall of the feed pipe 31 is in sliding fit with the annular guide rail 21 provided on the tank cover 2.

[0032] In an embodiment of the present utility model: A protective cover 22 is fixedly connected to the top of the tank cover 2 around the feed pipe 31, and the other end of the rotary joint 32 penetrates through the side of the protective cover 22.

[0033] In an embodiment of the present utility model: A driving component 5 for driving the feed pipe 31 to rotate is provided in the protective cover 22. The driving component 5 includes a motor 51, a driving pulley 52, a transmission belt 53, and a driven pulley 54.

[0034] In an embodiment of the present utility model: The motor 51 is fixed to the top of the tank cover 2, and the driving pulley 52 is arranged on the top output end of the motor 51.

[0035] In an embodiment of the present utility model: The driven pulley 54 is arranged at the top end of the outer wall of the feed pipe 31, and the driving pulley 52 is in transmission connection with the driven pulley 54 through the transmission belt 53.

[0036] In an embodiment of the present utility model: The lower part of the filtering tank 1 is in a funnel shape, and an electromagnetic valve 6 is provided at the bottom discharge port of the filtering tank 1. The filtering equipment main body further includes a support base 7. The support base 7 is located directly below the filtering tank 1 and is used to support the entire filtering tank 1.

[0037] Example 1. Please refer to the attached Figure 1 - attached Figure 7 , during the process of the driving component 5 driving the spreading component 3 to rotate, the protective cover 22 limits the rotary joint 32 to prevent the feed pipe 31 from driving the outer shell of the rotary joint 32 to rotate. At the same time, the inclined outer wall of the material guiding cover 33 provides a good buffering effect for the falling slurry, preventing the flat membrane on the top of the support mesh 42 from cracking after being impacted by the slurry. The baffle cover 311 provided at the bottom end of the feed pipe 31 is not only used to connect the material guiding cover 33 but also used to prevent the falling slurry from splashing everywhere.

[0038] Example 2. Please refer to the attached Figure 2 And attached Figure 4The flat membrane is usually made of polymer materials or inorganic materials. The pore size of the flat membrane is determined according to the accuracy requirements of graphene slurry filtration. When a certain amount of graphene particles are retained on the flat membrane, the circular frame 41 can be drawn out to collect the graphene particles.

[0039] Specifically, by setting up the paving component 3, the graphene slurry is poured into the feed pipe 31 from the rotary joint 32. After the slurry falls on the top of the material guide cover 33 along the feed pipe 31, it is immediately dispersed toward the inclined outer wall of the material guide cover 33. During this process, the driving component 5 always slowly drives the entire paving component 3 to rotate. The rotating material guide cover 33 evenly spreads the slurry on its outer wall from the discharge port 331 to the flat membrane on the top of the support net 42. At the same time, the rotating backward curved blade 35 spreads the slurry on the flat membrane evenly, effectively promoting the flow of the slurry, preventing local accumulation or stagnation of the slurry on the flat membrane, which is beneficial for the liquid to pass through the flat membrane, while the graphene particles are retained.

[0040] Specifically, by setting up the filter assembly 4, the circular frame 41 can be slidably installed on the semi-ring opening 11, which is convenient for replacing the flat membrane on the top of the support net 42. At the same time, it is convenient to collect the graphene particles intercepted on the flat membrane. The support net 42 effectively provides support for the flat membrane, ensuring that the flat membrane will not break during the filtration process, which is beneficial to improving the service life of the flat membrane.

[0041] Working principle:

[0042] First, the graphene slurry is poured into the feed pipe 31 from the rotary joint 32. After the slurry falls along the feed pipe 31 and falls on the top of the material guide cover 33, since the material guide cover 33 is a cone, the slurry is immediately dispersed from the inclined outer wall of the material guide cover 33. At the same time, the running motor 51 drives the active pulley 52 to rotate, and drives the driven pulley 54 to rotate through the transmission belt 53. The rotating driven pulley 54 drives the feed pipe 31 to rotate, thereby driving the entire paving assembly 3 to rotate, wherein the rotating material guide cover 33 evenly spreads the slurry on its outer wall from the discharge port 331 to the flat membrane on the top of the support net 42. In this process, the liquid passes through the flat membrane and is discharged through the electromagnetic valve 6, while the graphene particles are retained. At this point, the entire work process ends.
