Description

Technical Field

[0001] The present invention relates to the technical field of aluminum ash recovery, and more specifically, to an aluminum ash separation device for recovery. Background Art

[0002] During the production and processing of aluminum, such as electrolytic aluminum, aluminum alloy casting, and aluminum product processing, a large amount of aluminum ash is inevitably generated. Aluminum ash contains a certain amount of recyclable metallic aluminum, as well as other substances such as aluminum oxide and aluminum nitride. Recycling the metallic aluminum in aluminum ash has important economic and environmental significance. From an economic perspective, recycling metallic aluminum can reduce a company's raw material costs, improve resource utilization, and increase the company's economic benefits. For example, in an electrolytic aluminum plant, recycling the aluminum in aluminum ash can reduce dependence on primary resources such as bauxite and reduce production costs. Secondly, if the aluminum ash is randomly piled or improperly disposed of, harmful substances (such as fluoride and cyanide) may seep out, contaminating the soil, water, and air, and causing harm to the ecological environment and human health.

[0003] The aluminum ash separation and recovery equipment in the prior art is mainly composed of an ash roaster, an ash cooler and a ball mill screening device in actual processing. The aluminum ash after being discharged from the furnace is poured into the ash roaster by a forklift, and the internal anchor-type stirring paddle is used to separate the aluminum ash, and the aluminum slag floats on the surface. The aluminum liquid is introduced into the aluminum water bucket from the aluminum water tank at the bottom. The remaining aluminum slag is pushed to the ash cooler through the pot door under the action of the stirring paddle for rapid cooling, thereby reducing the oxidation and burning loss of pure aluminum. The cooled aluminum ash then enters the ball mill for dispersion and grinding, and finally enters the screening machine for vibrating powder screening, which is convenient for subsequent remelting. However, in actual processing, the material is transported to the ash roaster by the bucket on the forklift, and its transport volume is difficult to control. If too much material is loaded at one time, the temperature inside the ash roaster will drop rapidly, which will inevitably affect the separation effect of the aluminum ash. Secondly, the traditional aluminum ash is not provided with a mechanical structure for pre-treatment before entering the equipment. During processing, since the aluminum ash to be processed usually contains a large volume of material, directly entering the stirring furnace will inevitably affect its smelting efficiency.

[0004] Therefore, in view of this, the inventor, adhering to many years of rich experience in design, development and actual production in the relevant industry, has researched and improved the existing structure and deficiencies, and provided a recycling aluminum ash separation equipment in order to achieve a more practical purpose. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, an embodiment of the present invention provides an aluminum ash separation equipment for recycling, which realizes quantitative loading through a turning mechanism in conjunction with a moving mechanism. The material is now quantitatively transported to the inside of a weighing box through a feeding auger in the feeding unit for weighing. The transportation is stopped immediately after the standard is met, and then the driving motor in the moving mechanism is controlled to drive the support table to slide along the outer wall of the guide rail, thereby controlling the weighing box to pass through the feed port and enter the top of the furnace, and coordinating with the control of the turning motor in the turning mechanism to rotate, driving the turning table and the driving motor to turn over inside the support table, thereby realizing pouring the material into the furnace for processing, thereby reducing the problem that the temperature inside the ash roasting machine is affected by the feeding amount. By pre-treatment The unit aluminum ash slag is pretreated by driving the rolling motor and the driving wheel to rotate, thereby driving the driven wheel and the transmission shaft to rotate inside the mounting table. At the same time, the driving seat drives multiple rolling wheels to roll on the upper surface of the granulation plate, and at the same time, the aluminum ash slag is crushed and extruded into granules through the surface of the granulation plate, which is convenient for subsequent processing. Secondly, after the material is loaded, the rotating seat is pulled downward by controlling the electric cylinder, thereby driving the driving plate to pull the connecting plate to move together, and driving the fixed shaft and the partition to slowly close along the inner wall of the feed port, thereby reducing the outflow of internal high temperature, improving the stability of the melting temperature, and further improving the practicality of the device to solve the problems raised in the above background technology.

[0038] Working principle of the present invention: During actual processing, the present invention first pours the aluminum ash into the grinding box 52 of the pretreatment unit 5 through the guide trough 6, starts the grinding motor, drives the driving wheel 58 to rotate, the driving wheel 58 engages the driven wheel 57, and causes the transmission shaft 56 to rotate in the mounting table 59, and then the driving seat 54 drives multiple grinding wheels 55 to roll on the granulation plate 53, crushing the aluminum ash slag and squeezing it into granules, and the granular aluminum ash falls into the lower hopper 51 through the holes in the granulation plate 53, and then enters the feeding barrel 43 of the feeding unit 4 through the discharge port at the lower end of the lower hopper 51, and the feeding motor 44 works to drive the conveying shaft 41 and the feeding auger 42 to rotate, and the granular aluminum ash in the feeding barrel 43 is conveyed upward, and the material falls into the feeding unit 4 through the buffer plate slot 7. In the weighing box 39 of element 3, when the material in the weighing box 39 reaches the set weight, the feeding motor 44 stops, and then the driving motor 36 starts, and the driving gear 37 at its output end rolls on the gear plate 38, driving the support platform 33 to slide along the guide rail 32, so that the weighing box 39 moves toward the feed port 2 of the ash roasting machine body 1. When the weighing box 39 reaches above the feed port 2, the turning motor 34 starts, driving the turning platform 35 and the weighing box 39 to turn over, and pour the material into the melting furnace 111 of the ash roasting machine body 1. The stirring motor 115 drives the driving shaft 114 and the stirring blade 113 to rotate, stirring and separating the aluminum ash in the melting furnace 111. During this process, the aluminum liquid is discharged and collected through the aluminum liquid discharge trough 112, and the aluminum slag floats on the surface;

[0039] If it is necessary to improve the stability of the melting and stirring temperature inside the furnace 111, after the material is loaded, start the electric cylinder 13, and the electric cylinder 13 pulls the rotating seat 12 to move downward, driving the driving plate 11 to pull the connecting plate 10, and then the fixed shaft 8 and the partition 9 are slowly closed along the inner wall of the feed port 2, reducing the outflow of internal high temperature, and completing the aluminum ash separation process. The above steps can be repeated according to actual needs to process more aluminum ash.
