Description

Technical Field

[0001] This utility model relates to the field of drying equipment technology, and in particular to a flake graphite drying device. Background Technology

[0002] Flake graphite is a natural phanerocrystalline graphite, resembling fish scales in shape. It belongs to the hexagonal crystal system and has a layered structure. It possesses excellent properties such as high temperature resistance, electrical conductivity, thermal conductivity, lubrication, plasticity, and acid and alkali resistance. Flake graphite is widely used in high-grade refractory materials and coatings in the metallurgical industry. During the processing of flake graphite, it is necessary to keep it dry, so drying equipment is required to remove moisture from the flake graphite. However, currently, when flake graphite is dried in the drying equipment, it tends to accumulate inside the equipment and cannot fully contact the heated gas, reducing the drying efficiency of the flake graphite and resulting in incomplete drying. Utility Model Content

[0003] This utility model discloses a flake graphite drying device, which solves the problem that flake graphite is prone to accumulate in the drying device and cannot fully contact the heating gas, thus reducing the drying efficiency of flake graphite.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A flake graphite drying device includes a cylinder, a connecting cylinder with an arc-shaped top inside the cylinder, and a spiral conveying assembly with its top extending into the connecting cylinder. A first fan for blowing hot air into the cylinder is fixed on the cylinder, and a second fan for blowing hot air into the connecting cylinder is also fixed on the cylinder.

[0006] Compared with the prior art, the present invention has the following beneficial effects:

[0007] Graphite is conveyed into the cylinder, where it falls to the top of the connecting cylinder and then scatters downwards. Hot air from the first blower is then discharged into the cylinder to dry the graphite. When graphite accumulates in the cylinder, the screw conveyor assembly activates, transporting the accumulated graphite towards the connecting cylinder before discharging it. As the graphite falls from the connecting cylinder, hot air from the second blower continues to dry it. Through the screw conveyor assembly, graphite accumulated in the cylinder and located below the connecting cylinder is continuously conveyed upwards before falling downwards for drying. This invention allows for rapid drying of graphite, preventing it from accumulating and failing to fully contact the heating gas, thus improving drying efficiency. Attached Figure Description

[0011] The specific content of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0012] like Figure 1 and Figure 2 As shown, this utility model provides a flake graphite drying device, including a cylinder 1, a connecting cylinder 2 with an arc-shaped top inside the cylinder 1, and a spiral conveying assembly with its top extending into the connecting cylinder 2 inside the cylinder 1; a first fan 4 for blowing hot air into the cylinder 1 is fixed on the cylinder 1, and a second fan 5 for blowing hot air into the connecting cylinder 2 is also fixed on the cylinder 1. After the graphite is fed into the cylinder 1 through the feed end at the top of the cylinder 1, it falls onto the top of the connecting cylinder 2 and then disperses and falls evenly downwards. At this time, the hot air discharged by the first blower 4 can dry the graphite. When the graphite falls to the bottom of the cylinder 1, the screw conveyor assembly can transport the graphite upwards and into the connecting cylinder 2, where it falls downwards. The hot air discharged by the second blower 5 can then continue to dry the graphite, preventing it from accumulating at the bottom of the cylinder 1 during drying and ensuring that the graphite can fully contact the hot air during the drying process.

[0013] like Figure 1As shown, the spiral conveying assembly includes a vertical cylinder 3 fixed inside the cylinder 1. An auger 31, extending from the bottom of the vertical cylinder 3, is rotatably connected inside the vertical cylinder 3. A rotating shaft connected to the top of the vertical cylinder 3 and a motor 32 are fixed to the top of the auger 31. The discharge end of the vertical cylinder 3 is located inside the connecting cylinder 2. The main body of the motor 32 is fixed to the top of the vertical cylinder 3. Starting the motor 32 drives the auger 31 to rotate, which in turn conveys the graphite located at the bottom of the cylinder 1 upwards into the vertical cylinder 3. The graphite is then discharged through the discharge end of the vertical cylinder 3, causing it to fall downwards from the connecting cylinder 2. As the graphite falls downwards, hot air blown by the second blower 5 dries it. The auger 31 continuously conveys the graphite upwards, preventing graphite accumulation inside the cylinder 1 and ensuring sufficient contact between the graphite and the hot air.

[0014] like Figure 1 As shown, a protective shell 33 is fixed to the top of the vertical cylinder 3 and is fixed to the inner wall of the connecting cylinder 2. A connecting pipe is connected to the protective shell 33, passing through the connecting cylinder 2 and the cylinder body 1 in sequence. The motor 32 is located inside the protective shell 33. A fixing rod 34 connected to the inner wall of the cylinder body 1 is fixed to the vertical cylinder 3. The protective shell 33 can effectively protect the motor 32, and can also accelerate the air circulation inside the protective shell 33 through the connecting pipe, so as to avoid the temperature inside the protective shell 33 being too high and affecting the normal use of the motor 32. The fixing rod 34 can effectively fix the vertical cylinder 3 inside the cylinder body 1.

[0015] like Figure 1 As shown, a funnel-shaped feeding cylinder 35 is fixed inside the connecting cylinder 2. The discharge end of the vertical cylinder 3 is located inside the feeding cylinder 35. A fixed cylinder 36 with a conical top and located below the feeding cylinder 35 is fixed on the vertical cylinder 3. After the graphite is discharged into the feeding cylinder 35 through the discharge end of the vertical cylinder 3, the feeding cylinder 35 can evenly discharge the graphite to the top of the fixed cylinder 36. Then, the graphite falls evenly downward through the gap between the outer wall of the fixed cylinder 36 and the inner wall of the connecting cylinder 2, so that the graphite can be effectively dispersed when it falls, so that the hot air discharged by the second fan 5 can effectively dry the graphite.

[0016] like Figure 1 and Figure 2 As shown, an annular shell 51 located below the feeding cylinder 35 is fixed on the inner wall of the connecting cylinder 2. The exhaust end of the second blower 5 is connected to the annular shell 51, and perforations are provided on the inner wall of the annular shell 51. A guide ring 52 with an inclined inner wall is fixed on the top of the annular shell 51. When the second blower 5 blows hot air into the annular shell 51, the hot air can be evenly discharged through the perforations on the inner wall of the annular shell 51, so as to effectively dry the graphite falling down through the fixed cylinder 36, allowing the graphite to fully contact the hot air; the guide ring 52 can prevent graphite from accumulating on the top of the annular shell 51.

[0017] like Figure 1 and Figure 2 As shown, a fixed shell 41, which covers the connecting cylinder 2 and is in the shape of an annular ring, is fixed on the inner wall of the cylinder 1. A round hole is opened on the inner wall of the fixed shell 41, and the exhaust end of the first fan 4 is connected to the fixed shell 41. A connecting rod 42 is fixed between the fixed shell 41 and the connecting cylinder 2, and a vertical rod 21 is fixed between the connecting cylinder 2 and the cylinder 1. After the No. 1 fan 4 blows hot air into the fixed shell 41, the hot air can be discharged through the round hole on the inner wall of the fixed shell 41. When the graphite falls evenly downwards after landing on the top of the connecting cylinder 2, the hot air can fully contact the graphite and effectively dry it. There are at least two No. 1 fans 4 and two No. 2 fans 5. The exhaust end of the No. 1 fan 4 passes through the cylinder 1 and is connected to the fixed shell 41. The exhaust end of the No. 2 fan 5 passes through the cylinder 1 and the connecting cylinder 2 in sequence and is connected to the annular shell 51. A set of connecting rods 42 is provided. When the graphite falls downwards through the gap between the outer wall of the connecting cylinder 2 and the inner wall of the fixed shell 41, it can interfere with the graphite so that the graphite can make more full contact with the hot air. The vertical rod 21 can fix the connecting cylinder 2 inside the cylinder 1. The vertical rod 21 is fixed at the top of the connecting cylinder 2 and connected to the top inside the cylinder 1.

[0018] like Figure 1 As shown, the cylindrical body 1 contains a ring-shaped movable shell 6 located above the fixed shell 41. The top of the connecting cylinder 2 is located inside the movable shell 6. The inner ring surface of the movable shell 6 has holes. A third fan 61 is fixed on the cylindrical body 1, and the exhaust end of the third fan 61 is connected to a flexible hose 62 that communicates with the movable shell 6. An exhaust pipe 8 is connected to the cylindrical body 1. When the stone falls to the top of the connecting cylinder 2, the third fan 61 can blow hot air into the movable shell 6 through the flexible hose 62. After the hot air is discharged through the holes on the inner wall of the movable shell 6, the graphite can be dried immediately. The exhaust pipe 8 can discharge the air inside the cylindrical body 1. An opening is provided on the cylindrical body 1 for the flexible hose 62 to pass through.

[0019] like Figure 1As shown, an electric telescopic rod 63 is fixed to the top of the cylinder 1. The telescopic end of the electric telescopic rod 63 is fixed to the top of the movable shell 6. The movable shell 6 is located between the connecting cylinder 2 and the fixed shell 41, and the inner diameter of the movable shell 6 decreases from top to bottom. Depending on the moisture content of the graphite, after activating the electric telescopic rod 63, the movable shell 6 can be driven to move downwards, so that the movable shell 6 can be inserted between the fixed shell 41 and the connecting cylinder 2. By reducing the distance between the inner wall of the movable shell 6 and the outer wall of the connecting cylinder 2, the flow rate of the graphite falling downwards is reduced. When the flow rate of the graphite falling downwards decreases, after the graphite falls to the top of the connecting cylinder 2, the hot air discharged from the holes on the inner wall of the movable shell 6 can better dry the graphite, increasing the contact time between the hot air and the graphite at the top of the connecting cylinder 2. Furthermore, when the flow rate of the graphite decreases, after the graphite enters between the fixed shell 41 and the connecting cylinder 2, the hot air discharged from the round holes on the inner wall of the fixed shell 41 can better dry the graphite.

[0020] like Figure 1 As shown, the bottom of the fixed shell 41 is connected to a vertical shell 9, and a nozzle is connected to the vertical shell 9. After the graphite falls to the bottom of the cylinder 1, the hot air in the fixed shell 41 can enter the vertical shell 9 and then be discharged through the nozzle to continue the drying operation on the graphite. The number of vertical shells 9 is set as one.

[0021] like Figure 1 As shown, a funnel-shaped collecting cylinder 7 is fixed at the bottom inside the cylinder 1. The bottom end of the auger 31 is located inside the collecting cylinder 7, and the bottom of the collecting cylinder 7 is connected to the discharge end at the bottom of the cylinder 1. The collecting cylinder 7 can concentrate the graphite falling into the lower part of the cylinder 1, causing the graphite to converge towards the bottom end of the auger 31, so that the auger 31 can transport the graphite upward.
