Description

Technical Field

[0001] This utility model belongs to the field of calcination treatment technology of aluminum ash, and in particular relates to a calcination device for secondary aluminum ash. Background Technology

[0002] Aluminum ash is a waste product generated during aluminum production. Secondary aluminum ash refers to the residue after primary processing. It is processed at high temperatures using a calcination device to recover aluminum or other useful components, reduce harmful substances, and transform aluminum ash into high-value-added products (such as alumina, calcium aluminate, and refractory materials) through calcination. The calcination device plays a crucial role in the resource utilization of secondary aluminum ash.

[0003] A search revealed that publication number CN220552262U, with an application date of August 12, 2023, discloses a calcination device for secondary aluminum ash, comprising: a base, a calcination drum for calcining secondary aluminum ash installed on the base, first support frames installed on both sides of the base, the first support frames being located on both sides of the calcination drum, a support rod installed on the top of the first support frame, a second support frame provided between the front side of the support rod and the base, and a feeding pipe inserted into the center of the second support frame, with one end of the feeding pipe inside the calcination drum.

[0004] However, it still has the following drawbacks in practical use:

[0005] 1. After use, residue will adhere to the inner wall of the calcination drum of the existing secondary aluminum ash calcination device, which will affect the heat transfer efficiency of subsequent calcination, and thus affect the calcination efficiency and effect of aluminum ash. At the same time, manual cleaning will increase the workload and labor intensity.

[0006] 2. Existing secondary aluminum ash calcination devices use a feeding pipe for material feeding, which cannot achieve continuous and rapid feeding of aluminum ash, thus affecting the feeding efficiency. Therefore, we provide a secondary aluminum ash calcination device to solve the above-mentioned problems. Utility Model Content

Detailed Implementation

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Example 1

[0033] Please see Figures 1 to 4 This utility model is a calcination device for secondary aluminum ash, including a mounting base 100 and a movable base 200 placed on one side thereon. The upper surface of the movable base 200 is provided with a feeding assembly 300. The feeding assembly 300 includes a feeding rack 301 mounted on the surface of the movable base 200 and a first motor 302 mounted on one end of the front end face of the feeding rack 301. The output shaft of the first motor 302 is connected to a first rotating shaft 302a through a coupling.

[0034] Specifically, a lifting seat 101 is rotatably mounted on one end of the mounting base 100, and a furnace body 102 is rotatably mounted on top of the lifting seat 101. A furnace opening 102a is provided in the middle of one side end face of the furnace body 102, and a wheel 201 is provided at the bottom of the moving base 200. The other end of the first rotating shaft 302a passes through the bearing on the outer wall of the feeding rack 301 and is connected to the bearing on the inner wall of the feeding rack 301. A drive roller 302b is sleeved on the outer wall of the first rotating shaft 302a. A feeding belt 304 is sleeved on the outer wall of the drive roller 302b. An auxiliary roller 303 is provided on the other side of the inside of the feeding belt 304. The auxiliary roller 303 is rotatably mounted on the inner wall of the feeding rack 301.

[0035] Furthermore, the movable seat 200 can move forward and backward and left and right under the action of the wheels 201. The mounting seat 100, lifting seat 101 and furnace body 102 are all existing technologies, so they will not be described in detail here. Multiple auxiliary rollers 303 are provided, which can play an auxiliary role in the operation of the feeding belt 304.

[0036] The operation process of this embodiment is as follows: First, under the action of the moving seat 200, the top of the feeding belt 304 is moved to the furnace opening 102a position. Then, aluminum ash is placed on the feeding belt 304. Next, the first motor 302 is started. The output shaft of the first motor 302 rotates and drives the first rotating shaft 302a to rotate through the coupling. The rotation of the first rotating shaft 302a will drive the drive roller 302b on its outer wall to rotate. Under the action of multiple auxiliary rollers 303, the feeding belt 304 is driven to run, thereby conveying the aluminum ash on the feeding belt 304 into the furnace body 102. This can realize the rapid feeding of aluminum ash, which has high working efficiency and eliminates the need for manual operation, greatly reducing labor intensity.

[0037] Example 2

[0038] Please see Figure 3 , Figure 5 , Figure 6 and Figure 7 Based on Embodiment 1, unlike the first embodiment, a wall scraping assembly 400 is provided. The wall scraping assembly 400 includes a lifting frame 401 bolted to the outer wall of the feeding frame 301, and a second motor 402 mounted on the outer wall of the lifting frame 401. A drive pulley 402a is mounted on the output shaft of the second motor 402. The outer wall of the drive pulley 402a is connected to the outer wall of the driven pulley 403a via a belt. A second rotating shaft 403 is mounted in the middle of one end face of the driven pulley 403a. The other end of the second rotating shaft 403 passes through a bearing on the lifting frame 401. A first side plate 403b is fixed in the middle of the outer wall of the second rotating shaft 403. A motor 404 is mounted on the outer wall of the first side plate 403b. This solves the problems of reduced calcination efficiency and high labor intensity of manual cleaning caused by residue adhesion on the inner wall of the furnace in the existing technology.

[0039] Specifically, the output shaft of motor 404 passes through a bearing on the first side plate 403b and is connected to threaded rod 404a via a coupling. The other end of threaded rod 404a is rotatably mounted in a bearing on the second side plate 403c. A movable sleeve 405 is helically sleeved on the outer wall of threaded rod 404a. The tops of the first side plate 403b and the second side plate 403c are fixed to the outer wall of the second rotating shaft 403. The movable sleeve 405 is slidably sleeved on the outer wall of the second rotating shaft 403. A support plate 406 is provided directly above the second rotating shaft 403. The two ends of the inner wall of the support plate 406 are movably connected to the first connecting rod 406a and the second connecting rod 406b respectively via hinges. The other ends of the first linkage 406a and the second linkage 406b are movably connected to the two ends of the outer wall of the second rotating shaft 403 via hinges; the top of the movable sleeve 405 is movably connected to the support rod 405a via a hinge, and the other end of the support rod 405a is movably connected to the outer wall of the first linkage 406a via a hinge; a scraper 407 is provided on the outer side of the support plate 406; a connecting rod 408 is fixedly arranged in a horizontal array on the inner wall of the scraper 407, and the other end of the connecting rod 408 passes through the through hole on the support plate 406 and is connected to the limiting plate 408a; a spring 409 is sleeved on the outer wall of the connecting rod 408, and the spring 409 is located between the scraper 407 and the support plate 406.

[0040] Furthermore, the outer walls of the driving pulley 402a and the driven pulley 403a are connected by a belt drive to achieve synchronous movement. The external thread on the outer wall of the threaded rod 404a is screwed into the threaded hole on the movable sleeve 405, and the movable sleeve 405 is sleeved on the outer wall of the second rotating shaft 403. Therefore, the rotation of the threaded rod 404a can cause the movable sleeve 405 to move along the outer wall of the second rotating shaft 403. Under the action of the support rod 405a, the first connecting rod 406a, the second connecting rod 406b and the hinge, the support plate 406 can be opened. The limiting plate 408a and the scraper 407 are connected by the connecting rod 408 to achieve the function of connecting transmission. Under the elastic action of the spring 409, the distance between the scraper 407 and the support plate 406 can be adjusted to improve the applicable range.

[0041] The operation process of this embodiment is as follows: After aluminum ash is put into the furnace body 102, the aluminum ash can be calcined. After the calcined aluminum ash is discharged, the moving seat 200 is adjusted to move the scraper assembly 400 to the furnace opening 102a. Then, the scraper assembly 400 is pushed into the furnace body 102. Then, the motor 404 is started. The output shaft of the motor 404 rotates and drives the threaded rod 404a to rotate through the coupling. The external thread on the outer wall of the threaded rod 404a is screwed into the threaded hole on the moving sleeve 405. Therefore, the rotation of the threaded rod 404a drives the moving sleeve 405 to move axially along the second rotating shaft 403. Under the action of the hinge and the support rod 405a, the first connecting rod 406a is lifted. Then, the outer support plate 406 is unfolded through the second connecting rod 406b, so that the scraper 407 can contact the inner wall of the furnace body 102. The second motor 402 is started, and the output shaft of the second motor 402 rotates, driving the drive pulley 402a to rotate. The outer walls of the drive pulley 402a and the driven pulley 403a are connected by a belt drive. Therefore, when the drive pulley 402a rotates, it will drive the driven pulley 403a to rotate under the action of the belt. The rotation of the driven pulley 403a will drive the second rotating shaft 403 to rotate, thereby making the scraper 407 rotate synchronously and scrape off the residue attached to the inner wall of the furnace body 102, so as to avoid affecting the subsequent heat transfer efficiency and the calcination efficiency and effect of aluminum ash. Under the elastic action of the spring 409, the distance between the scraper 407 and the support plate 406 can be changed to increase the applicable range of the scraper assembly 400. At the same time, it can also avoid the scraper 407 making hard contact with the inner wall of the furnace body 102, which would cause damage to the inner wall of the furnace body 102.
