Description

Technical Field

[0001] The utility model belongs to the technical field of metal smelting, and particularly relates to a device for grading and recovering aluminum in aluminum ash slag. Background Art

[0002] The aluminum metal smelting process requires the coordination of a variety of equipment, including smelting furnaces, hammering equipment and forming molds used in the smelting process, as well as recovery equipment for processing aluminum slag. The aluminum slag can be processed by the aluminum slag recovery equipment, and the aluminum in the furnace slag can be selected, while the slag can be removed, thereby achieving the purpose of recycling and reusing resources to reduce production costs. The above-mentioned recovery device is mainly composed of three parts: a screening mechanism, a driving mechanism that provides power for it, and a shell arranged on its outside.

[0003] A Chinese patent application (or patent) with publication number CN217251462U discloses a grading recovery device for aluminum in aluminum ash slag. Aiming at the problem that the existing aluminum ash slag recovery device cannot grade and classify it, which greatly reduces the refining and recovery effect, the following scheme is proposed, which includes a box body, two brackets are symmetrically fixedly installed at the bottom of the box body, two grading boxes are movably installed on the box body, filter plates are fixedly installed at the bottom of the two grading boxes, and the leakage holes of the two filter plates are of different sizes, a driving motor is fixedly installed on one side of the box body, a feeding rod is fixedly installed on the output shaft of the driving motor, a pushing device is rotatably installed on one side of the box body, the pushing device is connected to the feeding rod in a transmission manner, four mounting rods are slidably installed on the box body, and movable rods are movably installed on the four mounting rods. The utility model can effectively grade and recover aluminum ash slag, greatly improving the refining and recovery effect.

[0004] The above-mentioned aluminum grading recovery device in aluminum ash slag is provided with two grading boxes, and the grading boxes are provided with two filter plates with different leakage holes. However, when the aluminum ash slag is screened, the particle size of the ash slag is also different, so it is impossible to accurately select aluminum from the aluminum ash slag, and the ash slag will also be recycled, resulting in the problem that the recycled aluminum component is impure and mixed with ash slag; and when the aluminum ash slag is screened by using the two filter plates with different leakage holes on the box body, the box body is performing up and down fluctuation screening, and its power comes from the impact force of the aluminum ash slag falling on the box body, but when the aluminum ash slag impacts the box body, part of the ash slag will be blocked in the leakage hole, which is difficult to remove and causes the part of the leakage hole to lose the screening function. To this end, we provide a grading recovery device for aluminum in aluminum ash slag to solve the above-mentioned problems. Utility Model Content

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Specific embodiment 1

[0030] See also Figure 1-3 The utility model is a grading recovery device for aluminum in aluminum ash, comprising a box frame 2, and a flotation box 3 and an ash box 4 mounted on the box frame 2, wherein a bearing member 301 for bearing aluminum ash is also installed in the flotation box 3, and a pushing member 302 is also installed above the bearing member 301 and in the flotation box 3, through which the pushing member 302 can not only push the ash floating on the flotation box 3 into the ash box 4, but also push the aluminum blocks retained on the bearing member 301 into the screening box 1.

[0031] Specifically, the supporting member 301 in the flotation box 3 includes a supporting plate 301a and a pneumatic rod 301b at the bottom thereof, and the supporting plate 301a can be pushed up and down by the pneumatic rod 301b. The pushing member 302 includes a pushing plate 302a and electric rods 302b at both sides of its shaft end, and the pushing plate 302 is driven to move back and forth above the flotation box 3 by the electric rod 302b.

[0032] Furthermore, material troughs 303 are provided at the tops of the left and right side walls of the flotation box 3, and slide grooves 304 for installing the pushing member 302 are provided at the front and rear side walls of the flotation box 3, wherein the material trough 303 on the left side of the flotation box 3 is connected to the ash port 401 of the ash box 4, and the material trough 303 on the right side is connected to the feed port 103 of the flotation box 1. At the same time, a controller 5 is also embedded on the front side wall of the flotation box 3.

[0033] The operation process of this embodiment is as follows: a proper amount of flotation solution is added into the flotation box 3, and then the aluminum ash slag material to be recovered is added into the flotation box 3. At that time, the ash slag with low density and light weight floats above the solution, and then the electric rod 302b in the pushing member 302 drives the pushing plate 302a on its shaft end to push the ash slag to the ash slag port 401, until it enters the ash slag box 4 and stops moving, and then the pneumatic rod 301b extends out and pushes out the supporting plate 301a on its top, and then the aluminum blocks retained thereon are also exposed to the liquid surface, and then the pushing plate 302a moves back under the action of the electric rod 302b, and pushes the aluminum blocks on the supporting plate 301a from the feed port 103 into the screening box 1 again. Specific embodiment 2

[0035] See also Figure 4-5 On the basis of the specific embodiment 1, a screening box 1 and a screening component 7 installed therein are also provided. At the same time, a wave component 8 is also installed at one end of the screening component 7. The wave component 8 can cause the screening component 7 to fluctuate up and down, thereby improving the screening fineness and preventing the aluminum blocks from being retained in the sieve holes of the screening plate 701.

[0036] Specifically, an angle plate 104 for installing the screening component 7 is installed on the inner inner wall of the screening box 1. The screening component 7 consists of a screening plate 701 and an elastic rod 702 at the bottom thereof, wherein the elastic rod 702 is composed of a large cylinder 702a and a small cylinder 702b that are slidably connected to each other, and a spring 702c is also installed in the large cylinder 702a. The wave component 8 includes a motor 801 and a shaft rod 803 on its shaft end, and a cam 804 is detachably installed on the shaft rod 803, and the cam 804 cooperates with the crescent plate 701a on the screening plate 701. The motor 801 is installed on the right outer wall of the screening box 1 through the frame 802.

[0037] Furthermore, a feed port 103 for connecting with the flotation box 3 is provided on the top of the left side wall of the screening box 1, and an axial hole 102 for cooperating with the shaft rod 803 is provided on the right side, and a recovery groove 101 for installing the baffle plate 6 is provided on the front side. There are two screening assemblies 7 in total, and the sieve holes of the screening plates 701 in the two screening assemblies 7 decrease successively from top to bottom.

[0038] The operation process of this embodiment is as follows: the aluminum block pushed into the screening box 1 by the push piece 302 on the flotation box 3 directly falls on the upper screening assembly 7. At the same time, the motor 801 in the wave assembly 8 works to drive the cam 804 on its shaft end to rotate. When the cam 804 rotates, it will alternately contact the crescent plate 701a on the upper screening plate 701 and the crescent plate 701a on the lower screening plate 701, thereby achieving the effect of driving the two screening plates 701 to fluctuate at the same time. When the screening plate 701 fluctuates, the elastic rod 702 at the bottom thereof also fluctuates accordingly, further improving the screening effect.
