Description

Technical Field

[0001] This invention belongs to the field of aluminum ash treatment technology, and particularly relates to an aluminum ash resource utilization treatment device. Background Technology

[0002] Aluminum ash is a waste generated during aluminum smelting or casting. Its main components depend on the raw materials and production process, and it mainly includes the following substances: aluminum shavings, aluminum powder, alumina, silicon, iron, magnesium, calcium oxide, etc. Among them, aluminum shavings are relatively large particles, while the rest are in powder form. When treating aluminum ash, these impurities need to be effectively separated and processed in order to achieve resource recycling or environmentally friendly treatment.

[0003] In existing technologies, aluminum ash processing often uses vibrating screens. However, vibrating screens can only roughly separate large aluminum chips and other powdery impurities from aluminum ash. The residual aluminum powder in the other powdery impurities cannot be separated, resulting in incomplete separation and poor separation effect. Summary of the Invention

[0004] To address the problems in the prior art, the present invention proposes the following technical solution:

[0005] An aluminum ash resource utilization treatment device includes a vertically arranged annular carrier plate and a separation box connected by a support rod. The separation box has an inclined filter screen in its inner cavity. The annular carrier plate includes an independently arranged separation part. The top of the annular carrier plate is provided with an annular groove, and no less than three separation plates are placed in the annular groove.

[0006] A drive mechanism is provided at the center of the annular carrier disk to drive the separation disk to rotate intermittently along the annular groove;

[0007] The outer wall of the separation box is equipped with a quantitative return mechanism and a vibrating motor arranged in opposite directions, and the output end of the vibrating motor is connected to the inclined high edge of the filter screen.

[0008] Aluminum ash entering from the top inlet of the separation box is separated into aluminum chips by vibration and filtration by a vibrating motor and a filter screen, and falls to the quantitative return mechanism. The remaining aluminum ash powder falls from the bottom outlet of the separation box onto the separation plate on the non-separation section. The separation plate on the non-separation section vibrates continuously under the vibration transmission of the support rod. The aluminum ash powder in the separation plate is separated from aluminum powder and other impurities by the vibration stratification principle. Then, it is rotated to the separation section by the drive mechanism for further separation and collection.

[0009] As a preferred embodiment of the above technical solution, the quantitative return mechanism includes a tray fixedly connected to the outer wall of the separation box, a receiving tray placed above the tray, and a gravity sensor installed on the tray.

[0010] As a preferred embodiment of the above technical solution, a side baffle is fixedly connected to the outer side of the tray, and the upper edge of the side baffle is higher than the top height of the tray.

[0011] As a preferred embodiment of the above technical solution, the driving mechanism includes a servo motor installed on the ground, a rotating column fixedly connected to the top output shaft of the servo motor, and multiple sets of limiting clips fixedly connected to the periphery of the rotating column, each set of limiting clips including two vertical clips.

[0012] The outer wall of the separation disc is fixed with a connecting plate, which matches the limiting clamp and is located between the two clamps.

[0013] As a preferred embodiment of the above technical solution, the aluminum ash resource recovery device further includes a PLC controller, which is electrically connected to a gravity sensor and a servo motor.

[0014] As a preferred embodiment of the above technical solution, the bottom of the annular groove at the top of the annular carrier is provided with universal balls, and the separation disc is placed on the universal balls.

[0015] As a preferred embodiment of the above technical solution, the bottom of the annular carrier disk is provided with feet.

[0016] As a preferred embodiment of the above technical solution, the separation box is an integrated design and consists of a feeding section, a separation section, and a discharging section from top to bottom;

[0017] The top inlet of the feeding section is located above the vibrating motor on one side, and the discharge section is an oblique conical cylinder with the lower discharge port directly opposite the next rotation position of the upper separation disc of the separation section.

[0018] As a preferred embodiment of the above technical solution, a carrier plate is fixedly connected to the outer wall of the separation box, and a vibration motor is installed on the top of the carrier plate.

[0019] The beneficial effects of this invention are as follows:

[0020] Compared to traditional vibrating screen separation, this invention can not only separate larger aluminum shavings, but also further separate fine aluminum powder from the remaining aluminum ash, resulting in a more thorough separation. Furthermore, the secondary vibration separation of the remaining aluminum ash is achieved through the vibration transmission generated during the operation of the filter screen, eliminating the need for additional power equipment, making it more environmentally friendly and practical.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0028] Example

[0029] like Figure 1 As shown, an aluminum ash resource utilization treatment device includes a vertically arranged annular carrier plate 10 and a separation box 20 connected by a support rod 14. The inner cavity of the separation box 20 is provided with an inclined filter screen 31. The outer wall of the separation box 20 is equipped with a quantitative material return mechanism 40 and a vibration motor 32 arranged opposite to each other, and the output end of the vibration motor 32 is connected to the inclined high edge of the filter screen 31.

[0030] like Figure 3 As shown, the annular carrier 10 includes an independently set separation section 11, that is, the vibration of the vibration motor 32 cannot be transmitted to the separation section 11. The top of the annular carrier 10 is provided with an annular groove, in which no less than three separation discs 61 are placed. In this embodiment, three separation discs 61 are used. The three separation discs 61 can be referred to as the feeding position separation disc 61, the vibration separation position separation disc 61, and the secondary separation position separation disc 61, respectively. The secondary separation position is the separation disc 61 on the separation section 11. The center of the annular carrier 10 is provided with a driving mechanism 50 for driving the separation discs 61 to rotate intermittently along the annular groove.

[0031] The working process of this invention is as follows: First, aluminum ash enters from the top feed inlet of the separation box 20. The aluminum ash is initially filtered and separated into aluminum chips by the filter screen 31, which fall to the quantitative return mechanism 40. At the same time, the vibration motor 32 drives the filter screen 31 to vibrate, thereby accelerating the filtration and separation and avoiding clogging of the filter screen 31. The remaining aluminum ash powder after the aluminum chips are separated is discharged from the bottom discharge outlet of the separation box 20 and discharged to the discharge position separation plate 61. After the receiving plate 43 receives the set amount of aluminum chips, the drive mechanism 50 drives the three separation plates 61 to rotate 120°. At this time, the separation plate 61 loaded with the remaining aluminum ash powder rotates to the vibration separation position, and the secondary separation position separation plate 61 rotates to the discharge position to continue to receive the remaining aluminum ash powder after the initial separation by the filter screen 31. In this invention, the vibration of the vibration motor 32 is transmitted through the connection of the carrier plate 33, the separation box 20, the support rod 14, and the annular carrier plate 10. The vibration will be transmitted to The separation disc 61, which is located at the vibration separation position, is loaded with the remaining aluminum ash powder. Under the principle of vibration stratification, the different density components in the remaining aluminum ash powder are caused to stratify according to their relative density. Vibration causes the heavier particles to move downwards, while the lighter particles move upwards, thereby achieving separation. In this invention, the aluminum powder in the remaining aluminum ash powder is relatively light, especially in the case of powder or granules, with a density of approximately 2.7 g / cm³, which is less than the density of other impurities. Therefore, the aluminum powder is located at the top after vibration. Then, after the next cycle of conversion driven by the drive mechanism 50, the separation disc 61, which is loaded with the remaining aluminum ash powder and has been vibrated and separated, rotates to the secondary separation position. At this time, the separation disc 61 and the remaining aluminum ash powder inside can be manually removed as a whole. Then, the top layer of aluminum powder is separated a second time, and other impurities are poured out. The empty separation disc 61 is placed in the secondary separation position, and this process is repeated.

[0032] Compared to traditional vibrating screen separation, this invention can not only separate larger aluminum shavings, but also further separate fine aluminum powder from the remaining aluminum ash, resulting in a more thorough separation. Furthermore, the secondary vibration separation of the remaining aluminum ash is achieved through the vibration transmission generated during the operation of the filter screen 31, eliminating the need for additional power equipment, making it more environmentally friendly and practical.

[0033] The quantitative return mechanism 40 includes a tray 41 fixedly connected to the outer wall of the separation box 20, a receiving tray 43 placed above the tray 41, and a gravity sensor 44 installed on the tray 41. The aluminum ash resource utilization device also includes a PLC controller, which is electrically connected to the gravity sensor 44 and the servo motor 51. The aluminum shavings content in the aluminum ash of this invention tends to have little fluctuation. When the aluminum shavings received by the receiving tray 43 reach a certain weight, the amount of remaining aluminum ash powder tends to be relatively small. That is, when the aluminum shavings received by the receiving tray 43 reach a set amount, the amount of remaining aluminum ash powder received by the separation tray 61 at the discharge position also reaches a certain amount. At this time, the PLC controller drives the servo motor 51 in the drive mechanism 50 to rotate.

[0034] A side baffle 42 is fixedly connected to the outer side of the pallet 41, and the upper edge of the side baffle 42 is higher than the top of the pallet 41. The side baffle 42 serves as a limit to prevent the receiving tray 43 from falling off the top of the pallet 41, ensuring that the separated aluminum chips can be collected.

[0035] The drive mechanism 50 includes a servo motor 51 mounted on the ground. The top output shaft of the servo motor 51 is fixedly connected to a rotating column 52. Multiple sets of limiting clips 53 are fixedly connected to the periphery of the rotating column 52. Each set of limiting clips 53 includes two vertical clips.

[0036] The outer wall of the separation disc 61 is fixed with a connecting plate 62, which matches the limiting clamp 53 and is located between the two clamps.

[0037] The design of the connecting plate 62 and the limiting clamp 53 ensures that the vibration of the separating disc 61 is not transmitted to the drive mechanism 50, and does not affect the rotation of the separating disc 61 by the drive mechanism 50; furthermore, it also facilitates the placement and removal of the separating disc 61 and the connecting plate 62 as a whole.

[0038] Universal ball bearings 13 are provided at the bottom of the annular groove at the top of the annular carrier 10, and the separation disc 61 is placed on the universal ball bearings 13. By providing the universal ball bearings 13, the sliding friction between the bottom of the separation disc 61 and the bottom of the annular groove is converted into rolling friction, reducing the friction force and making the rotation of the separation disc 61 more convenient.

[0039] The bottom of the annular carrier disk 10 is provided with feet 12.

[0040] The separation box 20 is a one-piece design and consists of a feeding section 21, a separation section 22, and a discharging section 23 from top to bottom;

[0041] The top inlet of the feeding section 21 is located above the vibrating motor 32 on one side. The discharge section 23 is an inclined conical cylinder, and the lower discharge port is directly opposite the next rotation position of the upper separation disc 61 of the separation section 11.

[0042] A carrier plate 33 is fixedly connected to the outer wall of the separation box 20, and a vibration motor 32 is installed on the top of the carrier plate 33.

[0043] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.
