Description

Technical Field

[0001] The utility model relates to the field of aluminum material recycling, especially a mixed feeding and melting device, which mixes aluminum chips and aluminum blocks and then feeds them into a melting furnace. Background Art

[0002] Figure 3 It is the rear view of the existing mixed feeding and melting device. As Figure 3 shown, the existing mixed feeding and melting device includes a melting furnace 1. Behind the melting furnace 1, there is an aluminum chip hopper 2 and an aluminum block hopper 5. The two hoppers 2 and 5 are arranged side by side left and right. The bottom wall of the aluminum chip hopper 2 is provided with an aluminum chip hopper blanking port 13. Below the aluminum chip hopper blanking port 13, there is an aluminum chip conveyor belt 4. The aluminum chip conveyor belt 4 extends obliquely upward and forward into the melting furnace 1. The bottom wall of the aluminum block hopper 5 is provided with an aluminum block hopper blanking port 12. Below the aluminum block hopper blanking port 12, there is an aluminum block conveyor belt 9. The aluminum block conveyor belt 9 extends obliquely upward and forward into the melting furnace 1. The working process is as follows: The aluminum block hopper 5 and the aluminum chip hopper 2 discharge materials synchronously according to a certain ratio. Specifically, the aluminum chips are put by the aluminum block hopper 5 through the aluminum block hopper blanking port 12 onto the aluminum block conveyor belt 9 and are sent by the aluminum block conveyor belt 9 into the melting furnace 1 to be melted into aluminum liquid for recycling; the aluminum blocks are put by the aluminum chip hopper 2 through the aluminum chip hopper blanking port 13 onto the aluminum chip conveyor belt 4 and are sent by the aluminum chip conveyor belt 4 into the melting furnace 1 to be melted into aluminum liquid for recycling. The two blanking ports 13 and 12 are respectively located on the vertical plane 14 where the midlines of the top walls of their respective hoppers 2 and 5 are located. Therefore, the horizontal distance between these two blanking ports 13 and 12 is relatively large, and the aluminum chip conveyor belt 4 and the aluminum block conveyor belt 9 will also have a relatively large horizontal distance, resulting in the structures of these two conveyor belts 4 and 9 not being compact in the left-right direction and taking up too much floor space. Summary of the Utility Model

[0003] The inventor studied the solution without disclosing it. As Figure 3 shown, in the prior art, the two hoppers 2 and 5 are arranged side by side left and right. If the two blanking ports 13 and 12 are to be close to each other, the blanking port 13 of the left hopper (aluminum chip hopper 2) has to be close to the right edge of the left hopper, and the blanking port 12 of the right hopper (aluminum block hopper 5) has to be close to the left edge of the right hopper, so that these two blanking ports 13 and 12 can be closely arranged, and then the two conveyor belts 4 and 9 can be closely arranged side by side left and right. However, this will cause the center of gravity of the left hopper to be seriously biased to the right and the center of gravity of the right hopper to be seriously biased to the left, resulting in an unstable structure.

[0004] Therefore, the utility model aims to provide a mixed feeding and melting device for aluminum chips and aluminum blocks, in which the structures of the two conveyor belts in the left-right direction are compact, the floor space is reduced; and the center of gravity of the two hoppers will not be seriously biased to the left or seriously biased to the right.

[0005] Mixed feeding and melting device for aluminum chips and aluminum blocks, including a melting furnace. There is an aluminum chip hopper and an aluminum block hopper behind the melting furnace. These two hoppers are provided with material dropping openings on their respective bottom walls. Below these two material dropping openings, there are two conveyor belts respectively. These two conveyor belts extend obliquely upwards and forwards into the melting furnace. The aluminum chip hopper and the aluminum block hopper are arranged side by side front and back, and the material dropping openings of these two hoppers are staggered left and right.

[0006] Furthermore, herringbone anti-slip ridges are provided on the top walls of the two conveyor belts.

[0007] Furthermore, a screw conveying mechanism is installed at the material dropping opening of the aluminum chip hopper. The screw conveying mechanism sends the aluminum chips from the material dropping opening of the aluminum chip hopper to the aluminum chip conveyor belt.

[0008] Furthermore, a discharge chute is installed at the material dropping opening of the aluminum block hopper. The discharge chute receives the aluminum chips falling from the material dropping opening of the aluminum block hopper and sends the aluminum chips to the aluminum block conveyor belt; a valve is installed on the discharge chute.

[0009] Furthermore, the valve includes a baffle. The baffle is located at a radial cross-section of the chute cavity of the discharge chute to close the discharge chute; it includes a cylinder. The baffle is connected to the cylinder, and the baffle is driven by the cylinder to move radially out of the discharge chute to open the discharge chute.

[0010] The beneficial effects are as follows: The two hoppers are arranged side by side front and back, and the two material dropping openings are also arranged side by side front and back. The two material dropping openings only need to be slightly staggered in the left-right direction, and the two conveyor belts can be closely arranged side by side. The material dropping openings of the hoppers are only slightly staggered and are still located near the center of the hoppers, not close to the edges of the hoppers. Therefore, the center of gravity of the hoppers will not change significantly in position and can maintain stability. Description of the Drawings

[0015] The following further elaborates on the present creation of the utility model in detail in conjunction with specific embodiments.

[0016] AsFigure 1 As shown, the mixed feeding and melting device for aluminum chips and aluminum blocks of the present utility model includes an aluminum chip hopper 2 and an aluminum block hopper 5, which are arranged side by side front and back. As Figure 2 shown, the vertical planes 14 where the midlines of the top walls of the aluminum chip hopper 2 and the aluminum block hopper 5 are located divide the top walls of the two into left and right symmetrical parts respectively. The blanking port 13 of the aluminum chip hopper is opened on the left side of the aluminum block hopper 5 in its own vertical plane 14, and the blanking port 13 of the aluminum chip hopper is opened on the right side of the aluminum block hopper 5 in its own vertical plane 14, so that these two blanking ports 12 and 13 are staggered by a distance d1 (10 cm) in the left-right direction. Below these two blanking ports 12 and 13, an aluminum block conveyor belt 9 and an aluminum chip conveyor belt 4 are respectively arranged, and these two conveyor belts 4 and 9 are also only staggered by a distance d1, that is, they are closely arranged left and right. In front of the two hoppers 2 and 5, there is a melting furnace 1, and the two conveyor belts 4 and 9 extend obliquely forward into the melting furnace 11.

[0017] A screw conveying mechanism 3 is installed at the blanking port 13 of the aluminum chip hopper. Aluminum chips fall from the blanking port 13 of the aluminum chip hopper onto the screw conveying mechanism 3, and then are sent out by the screw conveying mechanism 3 onto the aluminum chip conveyor belt 4, and then are sent into the melting furnace 1 by the aluminum chip conveyor belt 4 to be melted into aluminum liquid. Aluminum blocks and aluminum chips are fed to the melting furnace 1 synchronously in a fixed ratio. An outlet chute 6 is installed at the blanking port 12 of the aluminum block hopper. A baffle 7 (serving as a valve) is provided at a radial cross-section of the cavity of the outlet chute 6 to close the outlet chute 6; a cylinder 8 is installed at the bottom of the aluminum block hopper 5. The baffle 7 is driven by the cylinder 8 to move radially out of the outlet chute 6 to open the outlet chute 6, and the aluminum chips then fall from the aluminum block hopper 5 into the outlet chute 6, and then slide down onto the aluminum block conveyor belt 9 and are sent into the melting furnace 1 by the aluminum block conveyor belt 9 to be melted into aluminum liquid. Herringbone anti-slip ridges 10 are provided on the top walls of the two conveyor belts 4 and 9 to prevent the aluminum blocks and aluminum chips from sliding down.

[0018] It should be noted that, as Figure 3 shown, in the prior art, the two hoppers 2 and 5 are arranged side by side left and right, and the distance between their respective vertical planes 14 is d2. This distance is shown as d1 in the present utility model as Figure 2 shown, and d1 is less than d2. Therefore, the structures of the two conveyor belts 4 and 9 of the present utility model are compact in the left-right direction.

[0019] As described above, it is only the implementation mode of the present utility model creation, and does not limit the scope of patent protection. Those skilled in the art make non-substantive changes or substitutions based on the present utility model creation, and still fall within the scope of patent protection.
