When the drum 54 is installed, the height of the discharge port 545 is lower than the height of the feed port 544 , so that the raw materials of the cans can be screened and transported to the rear unloading belt conveyor 82 .

In the process of conveying the raw material of the flat cans from the roller screening machine 5 through the discharge guide hopper 411 to the rear unloading belt conveyor 82, it must pass through the hanging iron remover 4. The hanging iron remover 4 is the prior art, mainly by magnetic separation. The belt, the motor, the transmission component and the suspended steel frame are composed. The suspended iron remover 4 is connected with the magnetic separation belt. The motor drives the magnetic separation belt to rotate, and the belt rotates forward with the magnetic separation belt. When the belt conveyor 82 transports the flattened cans to the When the lower end of the suspended iron separator 4 is placed, the magnetic force of the magnetic separation belt will attract the iron cans and the iron metal profiles.

Due to the continuous forward movement of the magnetic separation belt, the aluminum cans and non-ferrous metal profiles in the raw materials are not affected by the magnetic force, and can pass freely. Inside Institution 6.

The iron cans and ferrous metal profiles in the raw materials are adsorbed by the magnet belt under the action of magnetic force, and then rotate in the running direction after adsorption, and scrape the iron cans and ferrous metal profiles into the iron hopper next to the hanging machine. , The entire magnetic separation process achieves complete separation of aluminum cans and non-ferrous metal profiles from ferrous cans and ferrous metal profiles.

In the present invention, there is one air selection elevator 6 and three flattening machines 7. There are four air ducts 61 at the air outlet connection port of the air selection elevator 6, and the four air ducts 61 are respectively connected with the four flattening machines 7. , to transport the collected cans to the flattening machine again for secondary flattening, and then transport the flattened cans to the belt conveyor 83 .

The crushing and screening process to cotton bale of the present invention is as follows:

The loader shovels the recovered cans cotton bales to the feeding port of the chain conveyor 1, starts the power supply of the chain conveyor, and the entire equipment of the chain conveyor 1 runs as a whole, so that the cans cotton bales are conveyed by the chain conveyor. direction to transport.

The cotton bales of the cans are transported by the chain conveyor 1 to the feeding hopper of the crusher 2, and then reach the inside of the crusher equipment through the feeding hopper. With the rotation of the main shaft in the equipment, the blades are driven to rotate, so that the cotton bales of the cans follow the blades of the main shaft. The crushed cans are disassembled and stirred to obtain the decomposed single flat cans. The disassembled cans fall out from the discharge port of the crusher 2 and naturally fall on the belt conveyor 81, from the belt conveyor 81 to the roller screening machine. 5.

The flattened cans after passing through the belt conveyor 81 are then dropped into the drum screening machine 5 through the feeding hopper for screening. Because the diameter of the circular holes of the drum screen in the drum screening machine 5 is Φ45mm, during the screening process, the raw materials of the flattened cans are The medium diameter ≤45mm will be screened out of the mesh screen of the drum screening machine. After the screen is screened out, it will hit the shell of the drum screening machine, and then naturally pass through the fine material discharge hopper at the lower end of the drum screening machine, and then fall to the hopper 1 and hopper 2 on the ground. inside.

The diameter of the crushed cans is ≥45mm. After the crushed aluminum cans are continuously screened by the drum screening machine 5, they are directly sent to the discharge button of the drum screening machine after passing through the screening material guide plate in the drum screening machine 5. The drum screening machine 5 directly drops onto the vibrating feeder 3 after discharging the material guide hopper.

The vibrating feeder 3 discharges the material evenly, and there are some super-long and super-large cans in the discharge that have not been decomposed. These large cans cannot flow into the next process, which will result in the inability to perform magnetic separation and air separation. Manual selection is required. Large pieces of flat cans are picked out, and the picked out large pieces are directly put into hoppers 3 and 4, and the flattened cans that have been selected and passed directly flow to the belt conveyor 82.

In the process of conveying the flattened cans from the belt conveyor 82, they must pass through the hanging iron remover 4. The hanging iron remover 4 is at the upper feeding end of the belt conveyor 82. When the belt conveyor 82 transports the flattened cans to the hanging iron remover At the lower end, the magnetic force of the magnetic separation belt will attract the iron cans and the iron metal profiles. Due to the continuous forward movement of the magnetic separation belt, the aluminum cans and non-ferrous metal profiles in the raw materials are not affected by the magnetic force, pass freely, and fall naturally to the air separation lifting mechanism 6 along the conveying direction of the belt conveyor 82 .

The iron cans and ferrous metal profiles in the raw materials are adsorbed by the magnet belt under the action of the magnetic force, and rotate in the direction of rotation after the adsorption, and scrape the iron cans and the ferrous metal profiles into the hopper 6 beside the hanging machine. The whole magnetic separation process achieves complete separation of aluminum cans and non-ferrous metal profiles from ferrous cans and ferrous metal profiles.

The flattened cans conveyed by the belt conveyor 82 directly flow into the air-selecting and lifting mechanism 6. After the aluminum cans and non-ferrous metal profiles fall into the air-selecting silo, the centrifugal fan is driven by the centrifugal fan motor to rotate and adjust to a certain degree. The aluminum cans are blown into the air selection pipe opposite the centrifugal fan under the action of the wind speed and blowing force, until they are blown into the silo to be flattened above the flattening machine.

The metal profiles that are heavier than aluminum cans cannot be blown by the wind, and naturally fall from the heavy debris outlet to the belt conveyor. After the belt conveyor rotates naturally, the heavy materials are naturally dropped into the hopper 6. Through the action of the wind force of the air duct, a single can is sent to the feed bin of the flattening machine for secondary flattening. After the 7 rollers of the flattening machine run at the same time, the cans fall out after being flattened for a second time and fall directly to the A material compartment, the flattened aluminum cans that are twice flattened by the flattening machine 7, are transported to the B material compartment by the belt conveyor 83 after discharging.

The invention uses the magnetic force to automatically select the iron cans, uses the wind to blow away the aluminum cans, and automatically drops the scrap metal profiles heavier than the aluminum cans, so that the aluminum cans are automatically selected; the flattening machine 7 The two rollers of the aluminum cans are rotated toward each other to automatically extrude the aluminum cans into the shape of flat sheets.

The invention smashes the recycled cotton bales of domestic garbage cans, automatically sorts the aluminum cans, and automatically extrudes them into flat sheets, which can improve the purity of aluminum water during secondary smelting and utilization of the aluminum cans, and reduce the occupation of the cans. space, thus saving transportation costs and improving the purity of the raw material melting furnace.

To sum up, the above are only preferred embodiments of the present invention, and are not intended to limit the scope of implementation of the present invention. That is, all equivalent changes and modifications made according to the content of the patented scope of the present invention shall belong to the technical scope of the present invention.
