Description

Technical Field

[0001] This application relates to the field of graphene storage technology, specifically a temporary storage tank for graphene powder production. Background Technology

[0002] The production process of modified graphene as an anti-wear agent is a multi-step and technology-intensive process. The core lies in the preparation of high-quality graphene, effective surface modification, and stable dispersion in lubricating oil.

[0003] In the production process of modified graphene anti-wear agents, the graphene powder storage tank (especially the dried powder after surface modification) is a key node connecting the modification, drying and dispersion processes. However, the graphene powder has poor flowability due to split agglomeration, making it difficult to feed and transport evenly. Therefore, this application proposes a storage tank for graphene powder production to solve these problems. Summary of the Invention

[0004] The technical problem to be solved by this application is to overcome the existing defects and provide a temporary storage tank for graphene powder production, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, this application provides the following technical solution: a temporary storage tank for graphene powder production, comprising an outer tank, wherein the outer tank is internally arrayed with no fewer than four inner tanks, and adjacent inner tanks do not contact each other. The bottom of the inner tank is conical and extends out of the outer tank. A flow-diverting component is provided on the upper surface of the outer tank, and a feed inlet is provided on the upper surface of the flow-diverting component. An arch-breaking component is provided in the conical hopper of the inner tank. The arch-breaking component includes an arch-breaking motor, a rotating shaft, and an arch-breaking rod. The arch-breaking motor is mounted on the conical hopper of the inner tank. The power output shaft of the arch-breaking motor passes through the inner tank and is connected to the rotating shaft. The other end of the rotating shaft is rotatably connected to the inner tank. An arch-breaking rod with adjustable height is provided on the outside of the rotating shaft.

[0006] Furthermore, the arch-breaking rod includes a fixed rod, a movable rod, a fixed seat, a connecting seat, and a driving structure. A fixed seat is provided on the outer side of the rotating shaft, and a fixed rod is hinged to the upper and lower ends of the fixed seat. A connecting seat is slidably connected to the rotating shaft, and a movable rod is hinged to the upper and lower ends of the connecting seat. The movable rod and the fixed rod are hinged together by a connecting shaft, and a driving structure is provided on one side of the connecting seat.

[0007] Furthermore, the connecting seat has two limiting grooves inside, and two limiting blocks are provided on the outer side of the rotating shaft at the corresponding positions of the limiting grooves.

[0008] Furthermore, the drive structure includes a push plate and a cylinder. The push plate is rotatably connected to one side of the connecting seat. The push plate has a hole to avoid the rotating shaft. One side of the push plate is connected to the telescopic end of the cylinder, and the cylinder is fixed to the conical hopper at the bottom of the inner tank by bolts.

[0009] Furthermore, the diversion assembly includes a diversion shroud, a diversion motor, a reducer, a main gear, a driven gear ring, and a diversion pipe.

Detailed Implementation

[0018] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments in this application (for ease of description and understanding, hereinafter referred to as...), Figure 2(The above is described above). All other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this application.

[0019] Please see Figure 1-3 This application provides a technical solution for a temporary storage tank for graphene powder production: a temporary storage tank for graphene powder production includes an outer tank 1, the outer tank 1 has an internal array of no less than four inner tanks 2, and two adjacent inner tanks 2 do not contact each other, the bottom of the inner tank 2 is conical and extends out of the outer tank 1.

[0020] There are four inner tanks 2, arranged in a 2x2 pattern inside the outer tank 1. Adjacent inner tanks 2 do not contact each other. The space between two adjacent inner tanks 2 is connected to the space between the outer tank 1 and the inner tanks 2, forming a temperature-maintaining space.

[0021] By setting up four inner tanks 2, the static pressure inside the inner tanks 2 can be reduced, and the small volume of the silo shortens the residence time of the powder, reduces the chance of contact between moisture or oxygen, and lowers the probability of agglomeration.

[0022] Furthermore, the outer tank 1 has a temperature-maintaining space inside, an inlet pipe 22 and an outlet pipe 23 on one side of the outer tank 1, and a support foot at the bottom of the outer tank 1.

[0023] The support feet can support the outer tank 1 and supply heat-insulating water to the outer tank 1 through the water inlet pipe 22, so that the internal temperature of the outer tank 1 is in a suitable range.

[0024] A flow divider 3 is provided on the upper surface of the outer tank 1, and a feed inlet 10 is provided on the upper surface of the flow divider 3.

[0025] Furthermore, the diversion assembly 3 includes a diversion shroud 4, a diversion motor 5, a reducer 6, a main gear 7, a driven gear ring 8, and a diversion pipe 9. The diversion shroud 4 is fixed above the outer tank 1. The reducer 6 is provided on the upper surface of the diversion shroud 4. The power input end of the reducer 6 is provided with the diversion motor 5. The power output end of the reducer 6 extends into the diversion shroud 4 and is connected to the main gear 7. The driven gear ring 8 is meshed on one side of the main gear 7. The driven gear ring 8 is fixed on the outside of the diversion pipe 9. The upper end of the diversion pipe 9 is rotatably connected to the feed inlet 10.

[0026] The flow divider 4 is sealed to the outer tank 1, and the reducer 6 is fixed to the flow divider 4 with bolts. The reducer 6 is located on the side of the feed inlet.

[0027] With this configuration, the power is transmitted from the diverter motor 5 to the reducer 6, which drives the main gear 7 to rotate, thereby causing the driven gear ring 8 to drive the diverter pipe 9 to rotate, thus moving the diverter pipe 9 above other compartments to facilitate the diversion and filling of materials.

[0028] Furthermore, an air inlet pipe 24 is provided on one side of the diffuser 4, and an air outlet pipe 25 is provided on the upper surface of the diffuser 4.

[0029] By setting the air intake pipe 25, inert gas can be filled into the diffuser 4 to prevent oxidation and moisture adsorption.

[0030] An arch-breaking assembly 11 is installed inside the conical hopper of the inner tank 2. The arch-breaking assembly 11 includes an arch-breaking motor 12, a rotating shaft 13, and an arch-breaking rod 14. The arch-breaking motor 12 is installed on the conical hopper of the inner tank 2. The power output shaft of the arch-breaking motor 12 passes through the inner tank 2 and is connected to the rotating shaft 13. The other end of the rotating shaft 13 is rotatably connected to the inner tank 2. An adjustable arch-breaking rod 14 is installed on the outside of the rotating shaft 13.

[0031] Specifically, the arch-breaking motor 12 can drive the rotating shaft 13 to rotate, thereby causing the rotating shaft 13 to drive the arch-breaking rod 14 to rotate, breaking up the bridging phenomenon at the bottom of the inner tank 2 and improving the material feeding efficiency.

[0032] Specifically, the connector 18 has two limiting grooves 26 inside, and two limiting blocks 27 are provided on the outside of the rotating shaft 13 at the corresponding positions of the limiting grooves 26. The limiting blocks 27 cooperate with the limiting grooves 26 to guide the connector 18.

[0033] Furthermore, the arch-breaking rod 14 includes a fixed rod 15, a movable rod 16, a fixed seat 17, a connecting seat 18, and a driving structure 19. A fixed seat 17 is provided on the outside of the rotating shaft 13. The fixed rod 15 is hinged to the upper and lower ends of the fixed seat 17. The connecting seat 18 is slidably connected to the rotating shaft 13. The movable rod 16 is hinged to the upper and lower ends of the connecting seat 18. The movable rod 16 and the fixed rod 15 are hinged together by a connecting shaft. A driving structure 19 is provided on one side of the connecting seat 18.

[0034] The connecting seat 18 can drive the movable rod 16 to slide along the rotating shaft 13, thereby adjusting the height of the movable rod 16 and the fixed rod 15, so as to deal with bridging phenomena at different heights.

[0035] Furthermore, the drive structure 19 includes a push plate 20 and a cylinder 21. The push plate 20 is rotatably connected to one side of the connecting seat 18. The push plate 20 has a hole for avoiding the rotating shaft 13. One side of the push plate 20 is connected to the telescopic end of the cylinder 21, and the cylinder 21 is fixed to the conical bucket at the bottom of the inner tank 2 by bolts.

[0036] The cylinder 21 can drive the push plate 20 to move, thereby causing the push plate 20 to drive the connecting seat 18 to move, thereby causing the connecting seat 18 to drive the movable rod 16 to slide along the rotating shaft 13, thereby adjusting the height of the movable rod 16 and the fixed rod 15, which is convenient for dealing with the bridging phenomenon in the inner tank 1. It should be noted that the hole on the push plate 20 avoids the rotating shaft 13, and also avoids the limit block 27 on the rotating shaft 13.

[0037] In use: When temporary storage is required, powder is fed into the inner tank 2 through the feed inlet 10. When the storage capacity of one tank reaches the limit, the feeding is stopped. The power is transmitted from the distributor motor 5 to the reducer 6, which drives the main gear 7 to rotate. This causes the driven gear ring 8 to drive the distributor pipe 9 to rotate, thereby moving the distributor pipe 9 above other compartments. Then, feeding continues, and the above operation is repeated until all four inner tanks 2 are filled. Then, inert gas is introduced into the pipe through the air inlet pipe 24 to reduce the contact between the powder and oxygen. Insulating water is supplied to the outer tank 1 through the water inlet pipe 22 to keep the internal temperature of the outer tank 1 within a suitable range.

[0038] When feeding material, the anti-bridging motor 12 can drive the rotating shaft 13 to rotate, thereby driving the anti-bridging rod 14 to rotate, breaking the bridging phenomenon at the bottom of the inner tank 2 and improving the feeding efficiency.

[0039] Meanwhile, the cylinder 21 can drive the push plate 20 to move, thereby causing the push plate 20 to drive the connecting seat 18 to move, thereby causing the connecting seat 18 to drive the movable rod 16 to slide along the limit block 27 on the rotating shaft 13, thereby adjusting the height of the movable rod 16 and the fixed rod 15, which is convenient for dealing with the bridging phenomenon in the inner tank 1.

[0040] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the appended claims and their equivalents.
