Description

Technical Field

[0001] This invention relates to the field of suction and unloading equipment, and in particular to a suction and unloading equipment for the production of carbon products. Background Technology

[0002] The suction and unloading overhead crane is a specialized piece of equipment in the calcination workshops of industries such as carbon, graphite, and anode materials. The suction and unloading overhead crane mainly consists of seven parts: bridge frame, trolley traveling mechanism, trolley traveling mechanism, suction and unloading system, cooling system, dust removal system, and electrical control system.

[0003] When high-temperature filler is transported into the silo using a suction pipe, a large amount of high-temperature flue gas is generated. This high-temperature flue gas enters the cyclone dust collector ash bin of the dust removal system through the airflow outlet at the top of the silo. The airflow that has undergone preliminary purification in the cyclone dust collector ash bin enters the cooling system for cooling. After cooling, the airflow finally enters the bag filter of the dust removal system for secondary dust removal and purification. The gas that has undergone secondary dust removal and purification is then discharged into the air after passing through a Roots blower and a silencer.

[0004] The cooling effect is limited because the cooling method only uses airflow outlets at the top of the silo, so improvements are needed. Summary of the Invention

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0031] Reference Figure 1-7 A carbon product manufacturing suction and unloading device includes a hopper 2, a suction pipe 11 is provided at the upper part of the hopper 2, a unloading pipe 6 is provided at the lower part of the hopper 2, a second cooling structure is provided on the suction pipe 11, an arch-breaking structure is provided inside the hopper 2, and a first cooling structure is provided on the arch-breaking mechanism.

[0032] In a specific embodiment of the present invention, by setting a second cooling structure at the suction pipe 11, the material can be cooled down when the suction pipe 11 sucks up the material. After the material is sucked into the hopper 2, the arch-breaking structure can agitate the material in the hopper 2, accelerate the dissipation of heat in the material, and allow the heat to be absorbed and cooled by the existing cooling system. At the same time, the first cooling structure in the hopper 2 can further cool down the material, thereby making the cooling effect of the material better.

[0033] The power source for the suction pipe 11 to draw in materials is existing conventional equipment.

[0034] The hopper 2, the first cooling structure and the second cooling structure are all set on the carrier 1. The carrier 1 is set on the traveling trolley. The traveling trolley is set on the trolley traveling mechanism. The setting method and specific structure are all based on existing conventional setting methods and conventional equipment.

[0035] The arch-breaking structure includes a rotating drum 20 and a mixing drum 19. The mixing drum 19 is fixedly mounted on the rotating drum 20. The rotating drum 20 and the mixing drum 19 are internally connected. The rotating drum 20 is rotatably mounted inside the hopper 2.

[0036] The top of the rotating drum 20 extends to the top of the hopper 2, and the bottom of the rotating drum 20 passes through the bottom of the hopper 2 and through the discharge pipe 6. The middle end of the discharge pipe 6 in this scheme is designed to be inclined so that the bottom end of the rotating drum 20 can pass through the discharge pipe 6.

[0037] The arch-breaking structure also includes a drive device, which includes a motor 15. The motor 15 is fixedly mounted on the top surface of the hopper 2 via a fixing frame 18. The motor 15 is connected to the top of the rotating drum 20 via a gear set. The gear set includes two meshing gears, which are respectively mounted on the output ends of the rotating drum 20 and the motor 15. The gear set transmits the rotational power output by the motor 15 to the rotating drum 20, enabling the rotating drum 20 to rotate and drive the mixing drum 19 to rotate, thereby achieving the effect of stirring the material and accelerating the heat dissipation of the material while breaking the arch.

[0038] The first cooling structure includes a first circulation tank 3, a first connecting pipe 4, and a second connecting pipe 17. One end of the second connecting pipe 17 is connected to the first circulation tank 3, and the other end is connected to the top of the rotating drum 20 through a second rotary joint 16. One end of the first connecting pipe 4 is connected to the first circulation tank 3 through a water pump, and the other end is connected to the bottom of the rotating drum 20 through a first rotary joint 5. The first circulation tank 3 stores water, and the water pump can circulate the water in the rotating drum 20 and the stirring drum 19 to achieve the effect of heat exchange and cooling.

[0039] The second cooling structure includes a heat exchange structure, which includes a main heat exchange tube 9 and two auxiliary heat exchange tubes 10. The main heat exchange tube 9 is fixedly installed inside the suction pipe 11. Both ends of the main heat exchange tube 9 pass through the suction pipe 11 and extend outside the suction pipe 11. Both ends of the main heat exchange tube 9 are connected to the two auxiliary heat exchange tubes 10 respectively. The cross-section of the main heat exchange tube 9 is spindle-shaped and vertically installed to avoid affecting the material passing through the suction pipe 11. The main heat exchange tube 9 and the auxiliary heat exchange tubes 10 are internally connected.

[0040] The second cooling structure also includes a second circulation tank 13, a third connecting pipe 8, and a fourth connecting pipe 14. One end of the third connecting pipe 8 is connected to the bottom end of one of the auxiliary heat exchange pipes 10, and the other end is connected to the second circulation tank 13 via a water pump. One end of the fourth connecting pipe 14 is connected to the top end of another auxiliary heat exchange pipe 10, and the other end is connected to the second circulation tank 13. The second circulation tank 13 contains water, and the water pump can circulate the water in the second circulation tank 13 within the heat exchange structure to achieve the effect of cooling the inside of the suction pipe 11.

[0041] A valve 7 is installed on the unloading pipe 6.

[0042] A vibrator 12 is installed on the suction pipe 11. The vibrator 12 can make the suction pipe 11 and the main heat exchange pipe 9 vibrate to prevent the material from sticking to the suction pipe 11 or the main heat exchange pipe 9 during the suction process.

[0043] Workflow: During material suction, the inlet of suction pipe 11 is placed at the location of the material to be suctioned, and then the material is suctioned into the hopper 2. During the suction process, the water pump in the second cooling structure is activated to draw water from the bottom of the second circulation tank 13, which then flows through the third connecting pipe 8 and into one of the auxiliary heat exchange pipes 10. The water then flows into the main heat exchange pipe 9. Since part of the main heat exchange pipe 9 is inside the suction pipe 11, it can carry away some of the heat from the suction pipe 11. The water then enters the second circulation tank 13 through the fourth connecting pipe 14, and the cycle continues. The material in the suction pipe 11 is pre-cooled. When the material enters the hopper 2, its high-temperature flue gas is discharged from the airflow outlet of the hopper 2 into the existing cooling system. At the same time, the motor 15 is started, which drives the rotating drum 20 to rotate, agitating the material and accelerating heat dissipation. Meanwhile, the water pump in the first cooling structure pumps water from the first circulation tank 3 through the first connecting pipe 4 into the rotating drum 20 and then into the mixing drum 19. The water then re-enters the first circulation tank 3 through the second connecting pipe 17. During this process, the water can carry away some of the heat in the hopper 2, making the cooling effect even better. When unloading, the valve 7 is opened, and gravity is used to complete the unloading operation.
