Description

Technical Field

[0001] This utility model relates to the field of aluminum ash treatment technology, specifically to an aluminum ash treatment mechanism. Background Technology

[0002] Aluminum ash is a product of the slag produced in the electrolytic or cast aluminum production process, which is then cooled and processed. Its main components are metallic aluminum, aluminum oxide, silicon dioxide, calcium oxide, magnesium oxide, and iron oxide. During the production of calcium aluminate, aluminum ash contains free carbon. This free carbon does not undergo reduction during smelting and remains in the refractory material as free carbon. When exposed to high temperatures, this free carbon oxidizes into gas and is released, causing blistering in the refractory material. Considering this, current technology typically installs bag-type settling boxes on the aluminum ash sintering kiln to handle the tail gas and collect the high-purity alumina ash produced during settling, thereby preventing blistering in the refractory material.

[0003] A search revealed that Chinese Patent (Publication No.: CN214233202U) discloses "a settling device for aluminum ash sintering kiln tail gas in calcium aluminate production, comprising at least a bag-type settling box and a striking device. The bag-type settling box is provided with a striking device on one side. The striking device includes at least a turntable. A rotating shaft is passed through the center of the turntable. The input end of the rotating shaft is connected to a driving device, and the other end is rotatably connected to a connecting rod. A protrusion is fixed to the outer end of the connecting rod. A movable frame with a mating structure is provided on the outer side of the protrusion. Two symmetrically positioned movable rods are fixed on both sides of the movable frame. A striking block is fixed on the movable rod facing the bag-type settling box. The outer end of the striking block contacts the outer surface of the bag-type settling box."

[0004] However, in the process of implementing the relevant technology, the above-mentioned technical solution has certain technical defects. For example, the patent uses a tapping device on one side of the settling tank to tap on one side to shake off the aluminum ash particles attached to the inner wall of the settling tank. However, since the aluminum ash particles will adhere to different areas of the inner wall of the settling tank with the flow of gas, the vibration effect of the tapping on one side extends to other areas and attenuates. It is impossible to shake off the aluminum ash particles in other areas of the inner wall of the settling tank except for the tapping point, which reduces the collection effect of aluminum ash.

[0005] In view of this, the present invention proposes an aluminum ash processing mechanism. Utility Model Content

[0006] This invention proposes an aluminum ash processing mechanism, which solves the problem that aluminum ash in different areas of the inner wall of the settling tank in the prior art cannot be completely shaken off and collected.

[0007] The technical solution of this utility model is as follows: an aluminum ash processing mechanism includes a mounting frame, a settling box fixedly connected to the inner side of the mounting frame, a feed pipe fixedly connected to one end of the top of the settling box, a discharge pipe fixedly connected to the other end of the top of the settling box, a rotating ring rotatably connected to the top of the mounting frame, a driving mechanism for driving the rotating ring to rotate provided at the bottom of the mounting frame, and a plurality of striking mechanisms provided on the inner side of the mounting frame for intermittently striking the outer wall of the settling box in coordination with the rotation of the rotating ring, the plurality of striking mechanisms being distributed at equal angles around the settling box.

[0008] Preferably, the striking mechanism includes a first slide rod penetrating the side wall of the mounting bracket, a striking element fixedly connected to one end of the first slide rod, a first wedge block fixedly connected to the other end of the first slide rod, a fixing plate fixedly connected to the outer side of the mounting bracket, a second slide rod slidably connected to one end of the fixing plate, a second wedge block fixedly connected to the bottom end of the second slide rod, the inclined surface of the second wedge block abutting against the inclined surface of the first wedge block, and an arc-shaped protrusion fixedly connected to the top end of the second slide rod.

[0009] Preferably, a first spring is sleeved on the first slide rod, one end of the first spring abuts against the outer wall of the mounting bracket, and the other end of the first spring abuts against the first wedge block.

[0010] Preferably, the striking element includes a mounting base fixedly connected to the end of the first slide rod, a slider slidably connected to one end of the mounting base, and a striking hammer fixedly connected to the outer side of the slider.

[0011] Preferably, the inner side of the mounting base is provided with a mounting groove that slides with the slider, and a second spring is sleeved on the inner side of the mounting groove. One end of the second spring is welded to the inner wall of the mounting groove, and the other end of the second spring is welded to the slider.

[0012] Preferably, the drive mechanism includes an internal gear ring fixedly connected to the inner side of the rotating ring, a fixed base fixedly connected to the bottom end of the mounting bracket, a motor fixedly mounted on the bottom of the fixed base, and a gear fixedly connected to the output shaft of the motor, the gear meshing with the internal gear ring.

[0013] Preferably, the driving mechanism further includes a plurality of connecting seats corresponding one-to-one with the arc-shaped protrusions. One end of each of the plurality of connecting seats is fixedly connected to the outer edge of the rotating ring. A pressure block is fixedly connected to the bottom of each of the plurality of connecting seats. The pressure blocks intermittently contact any one of the arc-shaped protrusions by cooperating with the rotation of the rotating ring.

[0014] The working principle and beneficial effects of this utility model are as follows:

[0015] 1. By setting up multiple striking mechanisms at equal angles around the settling tank, and controlling the rotation of the rotating ring through a drive mechanism, all striking mechanisms intermittently and synchronously strike different areas of the outer wall of the settling tank, avoiding the vibration attenuation problem caused by striking on one side. The striking covers all areas of the inner wall of the settling tank, ensuring that aluminum ash particles (such as high-purity alumina ash) are evenly shaken off, significantly improving the aluminum ash collection effect.

[0016] 2. The striking component adopts an elastic buffer design, including a slider, a second spring, and a mounting groove, to achieve elastic contact between the striking hammer and the settling box, avoiding damage to the settling box (such as deformation or cracks) caused by rigid striking, and reducing maintenance costs.

[0024] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0025] like Figures 1-5As shown, this embodiment proposes an aluminum ash processing mechanism, including a mounting frame 1. A settling box 2 is fixedly connected to the inner side of the mounting frame 1. A feed pipe 3 is fixedly connected to one end of the top of the settling box 2, and a discharge pipe 4 is fixedly connected to the other end of the top of the settling box 2. A rotating ring 5 is rotatably connected to the top of the mounting frame 1. A driving mechanism 7 for driving the rotating ring 5 to rotate is provided at the bottom of the mounting frame 1. Several striking mechanisms 6 are provided on the inner side of the mounting frame 1 to intermittently strike the outer wall of the settling box 2 in coordination with the rotation of the rotating ring 5. The several striking mechanisms 6 are distributed at equal angles around the settling box 2.

[0026] The exhaust gas is introduced into the feed pipe 3 for settling. Then, the drive mechanism 7 is activated to drive the rotating ring 5 to rotate, so that all the striking mechanisms 6 intermittently strike the outer wall of the settling box 2. This can prevent high-purity alumina ash from remaining on the inner wall of the settling box 3. Since the striking mechanisms 6 surround each other, when all the striking mechanisms 6 work together, they will strike different areas of the outer wall of the settling box 3, causing the aluminum ash residue in different areas of the inner wall of the settling box 3 to be shaken off, further improving the collection effect of high-purity alumina ash.

[0027] Furthermore, the striking mechanism 6 includes a first slide rod 61 that penetrates the side wall of the mounting bracket 1. One end of the first slide rod 61 is fixedly connected to a striking element 62, and the other end of the first slide rod 61 is fixedly connected to a first wedge block 63. A fixing plate 65 is fixedly connected to the outer side of the mounting bracket 1. A second slide rod 66 that penetrates the fixing plate 65 is slidably connected to one end of the fixing plate 65. A second wedge block 67 is fixedly connected to the bottom end of the second slide rod 66. The inclined surface of the second wedge block 67 abuts against the inclined surface of the first wedge block 63. An arc-shaped protrusion 68 is fixedly connected to the top end of the second slide rod 66. A first spring 64 is sleeved on the first slide rod 61. One end of the first spring 64 abuts against the outer wall of the mounting bracket 1, and the other end of the first spring 64 abuts against the first wedge block 63.

[0028] The drive mechanism 7 includes an internal gear ring 71 fixedly connected to the inner side of the rotating ring 5. A fixed seat 72 is fixedly connected to the bottom end of the mounting bracket 1. A motor 73 is fixedly installed at the bottom of the fixed seat 72. A gear 74 is fixedly connected to the output shaft of the motor 73. The gear 74 meshes with the internal gear ring 71. Several connecting seats 75 corresponding to the arc-shaped protrusions 68 are fixedly connected to the outer edge of the rotating ring 5. A pressure block 76 is fixedly connected to the bottom of each of the connecting seats 75. The pressure blocks 76 intermittently abut against any one of the arc-shaped protrusions 68 by cooperating with the rotation of the rotating ring 5.

[0029] By starting the motor 73, the gear 74 is driven to rotate, which in turn drives the internal gear ring 71 to rotate synchronously. This causes the rotating ring 5 to rotate, which in turn causes all the connecting seats 75 to drive the pressure blocks 76 to rotate circumferentially. When several pressure blocks 76 abut against the corresponding arc-shaped protrusions 68, the pressure blocks 76 apply downward pressure to the arc-shaped protrusions 68, causing the arc-shaped protrusions 68 to move downward. This causes all the second slide rods 66 to drive the second wedge blocks 67 to move downward, causing the second wedge blocks 67 to abut against the corresponding first wedge blocks 63 and apply downward pressure to them. This causes the first wedge blocks 63 to drive the corresponding first slide rods 6 When sliding occurs, the first spring 64 is compressed and accumulates potential energy, causing all the striking parts 62 to strike the outer wall of the settling box 2 simultaneously. When the pressure block 76 disengages from the arc-shaped protrusion 68, the first spring 64 releases its potential energy, causing the striking parts 62 to disengage from the settling box 2. This cycle repeats, allowing the striking parts 62 to strike the settling box 2 intermittently. Since the striking parts 62 are distributed at equal angles around the settling box 2, they can strike different areas of the settling box 2, causing the high-purity alumina ash residue adhering to different areas of the inner wall of the settling box 3 to be evenly shaken off, greatly improving the collection effect of high-purity alumina ash.

[0030] Furthermore, the striking component 62 includes a mounting base 621 fixedly connected to the end of the first sliding rod 61. A slider 622 is slidably connected to one end of the mounting base 621, and a striking hammer 623 is fixedly connected to the outer side of the slider 622. An installation groove 624 is formed on the inner side of the mounting base 621, which slides with the slider 622. A second spring 625 is sleeved on the inner side of the installation groove 624. One end of the second spring 625 is welded to the inner wall of the installation groove 624, and the other end of the second spring 625 is welded to the slider 622. The design of the second spring 625 ensures that the striking hammer 623 makes elastic contact with the settling tank 2, preventing damage to the settling tank 2 caused by rigid contact between the striking hammer 623 and the settling tank 2.

[0031] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
