Description

Technical Field

[0001] This utility model relates to the field of aluminum ore screening technology, specifically to an aluminum ore grading and screening device for kilns. Background Technology

[0002] Aluminum ores mainly include diaspore, boehmite, and gibbsite, all of which are used in aluminum smelting. They are white, or may appear light gray, light green, or light red due to impurities. They have a vitreous luster, with a pearly luster on cleavage surfaces.

[0003] Utility model patent CN220514713U discloses a grading and screening device for aluminum ore in a sealed furnace. The device includes a first housing, with first rectangular blocks fixedly installed on both the left and right sides of the inner cavity. A first spring is fixedly installed on the top of each rectangular block, and a support plate is fixedly connected to the top of the first spring. The left side of the support plate extends through the first housing, and a vibration motor is fixedly installed at the bottom of the support plate. A screening frame is fixedly connected to the inner side of the support plate. A dust removal device is provided on the side of the first housing. This dust removal device includes a second housing, with a fan fixedly connected to the bottom of the second housing and a pipe fixedly connected to the top of the left side of the second housing. This utility model, through the combined use of the second housing, fan, pipe, dust collection device, rectangular plate, and filter plate, has the advantage of dust removal, effectively reducing dust generation and ensuring a safe working environment for workers.

[0004] However, the aforementioned device still has some drawbacks in practical use. The most obvious is the lack of an iron removal component. When aluminum ore and iron are screened together, the iron falls onto the subsequent conveyor belt, easily causing tearing and resulting in significant economic losses. Therefore, to solve this problem, we propose an aluminum ore grading and screening device for kilns. Utility Model Content

A support bar 10 is connected to the top of one end of the inner wall of the screening box 1. A rotating groove 6 is formed at the top of the other end of the inner wall of the screening box 1. A covering component 7 is installed on the inner wall of the rotating groove 6 and the top of the inner wall of the screening box 1. The covering component 7 includes a support shaft 710 and two T-shaped positioning rods 73. The two sides of the shaft 710 are connected to the two sides of the inner wall of the rotating groove 6. The bottoms of the two T-shaped positioning rods 73 are respectively connected to the two sides of the top end of the screening box 1. The rotating sleeve 711 is sleeved on the outside of the support shaft 710. The side of the rotating sleeve 711 away from the support shaft 710 is connected to the cover plate 72. The bottom of the screening box 1 and the bottom of the screening frame 11 are connected to several collecting hoppers 8. The bottom of the collecting hopper 8 is connected to the flexible feeding pipe 9. The screening box 1 is in an inclined state. The height of the left side of the screening box 1 is higher than the height of the right side of the screening box 1. The height of the left side of the screening frame 11 is also higher than the height of the right side.

[0025] As a technical optimization of this utility model, a dust suction pipe 5 is connected to one side of the screening box 1, and the side of the dust suction pipe 5 away from the screening box 1 is connected to an external dust removal device; through the cooperation of the dust suction pipe 5 and the external dust removal device, the dust generated during the screening process of the screening box 1 can be sucked away.

[0026] As a technical optimization of this utility model, the inner wall of the screening box 1 is connected with several isolation strips 12, and the screening box 1 is divided into several screening areas by the isolation strips 12; the screening mesh of different screening areas gradually increases in size from left to right.

[0027] As a technical optimization of this utility model, a feed inlet 713 is provided through one side of the top of the cover plate 72. A U-shaped shield 71 is connected to the top of the cover plate 72 and outside the feed inlet 713. An electromagnetic plate 714 is connected to the bottom of the cover plate 72. The cover plate 72 is used in conjunction with the support bar 10. The U-shaped shield 71 can shield the aluminum ore raw material and prevent a large amount of aluminum ore raw material from falling on the top of the cover plate 72 during the process of adding it into the screening box 1.

[0028] As a technical optimization of this utility model, a damping plate 79 is sleeved on the outside of the T-shaped positioning rod 73. The bottom of the damping plate 79 is in sliding contact with the top of the cover plate 72. A positioning block 78 is connected to the top of the cover plate 72, and a bearing block 76 is connected to the center of one end of the top of the cover plate 72. The damping plate 79 can limit the position of the cover plate 72 and prevent the cover plate 72 from moving up and down too much.

[0029] As a technical optimization of this utility model, a return spring 712 is connected to both sides of the bearing block 76. A connecting block 75 is connected to the side of the return spring 712 away from the bearing block 76. A positioning rod 74 is connected to the side of the connecting block 75 away from the return spring 712. The side of the positioning rod 74 away from the connecting block 75 passes through the positioning block 78. Through the cooperation of the positioning rod 74 and the positioning block 78, the damping plate 79 can be positioned to prevent the damping plate 79 from rotating arbitrarily outside the T-shaped positioning rod 73.

[0030] As a technical optimization of this utility model, a support block 77 is slidably sleeved on the outside of the positioning rod 74, and the bottom of the support block 77 is connected to the top of the cover plate 72; the support block 77 can support the positioning rod 74 and improve the stability of the positioning rod 74 moving left and right.

[0031] In use, the external control terminal of the screening device is used to turn on the vibration motor 4 and the external dust removal equipment, and to energize the electromagnet 714. At this time, the electromagnet 714 generates magnetism, and the aluminum ore is added into the screening box 1 through the feed inlet 713. Under the cooperation of the vibration motor 4 and the support spring 2, the screening box 1 vibrates, and the aluminum ore moves to the right on the screening frame 11. The screening frame 11 is used to classify aluminum ore of different sizes. The screened aluminum ore falls into the collection hopper 8 and then falls from the flexible feed pipe 9 and is transported away by the subsequent conveying equipment. The dust generated during the screening process is drawn away by the dust suction pipe 5 and filtered by the external dust removal equipment.

[0032] Iron impurities in the aluminum ore are attracted by the electromagnetic plate 714, preventing them from entering the subsequent conveying equipment and causing the conveyor belt to be torn. During the downtime of the screening device, the two positioning rods 74 are moved towards each other to disengage them from the positioning block 78. During this process, the return spring 712 is extended, and then the damping plate 79 is rotated to disengage it from the top of the cover plate 72. The cover plate 72 is reversed so that the rotating sleeve 711 rotates outside the support shaft 710. After the cover plate 72 is opened, the iron impurities on the electromagnetic plate 714 are cleaned. After cleaning, each component is reset in sequence.

[0033] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
