Description

Technical Field

[0001] The utility model belongs to the technical field of upper thermal insulation materials for electrolytic aluminum cranes, in particular to a circulation recovery device for upper thermal insulation materials for electrolytic aluminum cranes. Background Art

[0002] Top-grade thermal insulation material is an important factor in maintaining the thermal balance of the electrolytic cell. After the thermal design of the electrolytic cell is determined, the balance between the top-grade thermal income and the top-grade thermal expenditure must be maintained during production to achieve smooth operation of the cell. Top-grade thermal insulation material mainly plays the role of maintaining the heat of the electrolytic cell, but it can also be used as a means of regulating thermal expenditure. By increasing or decreasing the thickness of the top-grade thermal insulation material, the thermal expenditure of the electrolytic cell can be increased or decreased. The top-grade thermal insulation material recycling and recovery device for electrolytic aluminum cranes specifically recycles and collects the top-grade thermal insulation material for electrolytic aluminum cranes, and refills it onto the anode carbon block through a distribution mechanism, thereby achieving the effect of recycling and reusing the thermal insulation material. At present, there is a lack of relevant top-grade thermal insulation material recovery devices on the market, resulting in waste of resources and increased costs for enterprises.

DETAILED DESCRIPTION

[0014] The specific implementation of the present invention will be further described in detail below with reference to the accompanying drawings.

[0015] Depend on Figures 1 to 2 It is given that the upper insulation material circulation and recovery device for electrolytic aluminum crane includes a volume separation system 1, a cooling system 2, a transverse conveying system 3, a material distribution system 4, a dust removal system 5 and a pneumatic system. The volume separation system 1 includes a suction nozzle 6, a material conveying pipe 7, a separator 8, a dust collector, a fan and a muffler. The pneumatic system includes an air storage tank 9, a centrifugal fan 10 and a pulse back-blow air compressor 11.

[0016] The suction nozzle 6 is a V-shaped suction nozzle.

[0017] The cooling system 2 adopts a multi-tube air-cooling structure.

[0018] The material distribution system 4 is provided with a first discharge pipe 12 .

[0019] The dust removal system 5 includes a cloth bag 13 and a second discharge pipe 14 .

[0020] Valves 15 are installed on the transverse conveying system 3 and the second discharge pipe 14 .

[0021] When the utility model is in use, the volume separation system 1 can use the pneumatic system to collect the insulation material. Under the joint action of the air storage tank 9, the centrifugal fan 10 and the pulse back-blowing air compressor 11, the suction nozzle 6 forms a negative pressure. The suction nozzle 6 adopts a V-shaped suction nozzle. The V-shaped suction nozzle can select different adsorption points for adsorption, which can more easily adsorb the insulation material at the edge of the electrolytic cell, so that the insulation material can be recovered to the maximum extent. The insulation material is transported to the feed pipe 7 through the suction nozzle 6. The insulation material is transported upward in the feed pipe 7. The feed pipe 7 is a round tube, which requires good sealing quality, small movement resistance, easy disassembly and assembly, and no pollution to the insulation material. The feed pipe 7 transports the insulation material to the separator 8. The mixed airflow of the insulation material and air enters the separator 8 along the tangential direction from the upper air inlet. Under the action of centrifugal force, The insulation material is thrown toward the cylinder wall, collides with the wall, and gradually loses speed. Under the action of gravity, it moves downward in a spiral line, and finally slides to the discharge port at the lower part of the cone cylinder of the separator 8 and enters the distribution system 4. The insulation material that has not entered the distribution system 4 can enter the distribution system 4 through the horizontal conveying system 3 after the valve 15 is opened.

[0022] Cooling system 2: Since the maximum temperature of the insulation material on the top of the electrolytic cell is greater than 600°C, cooling system 2 can cool the separated gas to ensure that the temperature of the insulation material after separation does not exceed 90°C. Cooling system 2 adopts a multi-tube air-cooling structure, which is simple to maintain and has a low failure rate;

[0023] The dust removal device can completely separate the dust in the pneumatic system to achieve the purpose of removing dust from the gas. The device adopts a high-temperature resistant cloth bag 13 to ensure its reliability. In order to ensure the dust removal effect, the device is integrated with a backflush device to ensure the air permeability of the cloth bag 13. The device is provided with an independent second discharge pipe 14, which can collect the residual insulation material in the gas or add it to the pole for continued use.

[0024] The pneumatic system adopts a suction-type system, which is not easy to generate dust during the transportation process and is environmentally friendly. In order to ensure sealing, all pipelines and warehouse bodies are sealed. In addition, the feeding pipe 7, the first discharge pipe 12 and the second discharge pipe 14 can be retracted and rotated, which has good flexibility and is convenient for collecting insulation materials.

[0025] This embodiment does not impose any formal restrictions on the shape, material, structure, etc. of the utility model. Any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the utility model are within the scope of protection of the technical solution of the utility model.
