Description

Technical Field

[0001] The utility model relates to the technical field of aluminum ash processing, in particular to a feeding device for aluminum ash pretreatment. Background Art

[0002] Aluminum ash slag refers to solid waste discharged during aluminum electrolysis, aluminum processing and recycled aluminum processing. Aluminum ash slag is an inevitable product of smelting, which can easily cause dust, ammonia and other pollution to the environment. According to the "National List of Hazardous Wastes 2021", aluminum ash slag has been classified as hazardous waste. Aluminum ash becomes alkaline when it comes into contact with water, which will destroy the pH of the soil. Therefore, aluminum ash slag must be handled in the correct way to avoid polluting the environment. In recent years, faced with increasingly severe environmental situations, the disposal of hazardous waste aluminum ash in the aluminum industry has become a focal issue in the industry.

[0003] In the process of primary and secondary aluminum ash treatment, due to the presence of large blocks of material between 200mm×200mm and 600mm×600mm, the large blocks of material waste time and energy when entering the ball mill, causing excessive damage to the ball mill and low working efficiency. In view of this, it is necessary to split the large blocks of aluminum and aluminum ash. The existing separation method is usually to pour the mixed material directly onto the sieve plate, but this method cannot remove the large blocks of aluminum in time, cannot fully and effectively play the advantages of the aluminum ash treatment process, and is not convenient for coordinated treatment of the entire process, resulting in poor connection of the entire treatment process and low production efficiency.

[0007] A sealing cover is provided on the top of the hollow cylinder; a driving member is provided on the sealing cover, a transmission shaft is provided at the output end of the driving member, the transmission shaft penetrates into the hollow cylinder, and the bottom end is limited and fixed by a bearing seat;

[0008] The transmission shaft is provided with a spiral blade, and the spiral blade is configured as a mesh blade.

[0009] Furthermore, a mounting plate is provided on the side wall of the bottom end of the hollow cylinder.

[0010] Furthermore, the bottom plate of the feed bin is arranged to be inclined.

[0011] Furthermore, the mesh size of the mesh plate and the spiral blade is the same.

[0012] Furthermore, the driving component at least includes a motor and a gearbox.

[0013] The beneficial effect of the utility model is that by adding a spiral blade with a mesh structure inside the feeding box, the aluminum block can be lifted upward for removal while separating the aluminum ash and the aluminum block, without the need for manual removal of the aluminum block, thereby improving the convenience of the aluminum ash processing process.

[0018] The following describes the implementation of the present invention through specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific implementations, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0019] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention, and thus the drawings only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed at will, and the component layout may also be more complicated.

[0020] Example 1

[0021] like Figures 1 to 3 As shown, a feeding device for aluminum ash pretreatment comprises a hollow cylinder 1, wherein the hollow cylinder 1 is configured as a cylindrical cylinder structure, and the upper and lower ends of the cylinder are respectively configured as openings;

[0022] A mesh plate 7 is provided at the bottom of the hollow cylinder 1 , and the mesh holes on the mesh plate 7 are used to separate aluminum ash and aluminum blocks; a cover 5 is provided at the top of the hollow cylinder 1 .

[0023] In order to facilitate the entry of materials and the output of aluminum blocks, the upper and lower sides of the hollow cylinder 1 are respectively provided with an outlet bin 3 and an inlet bin 2 connected to the hollow cylinder 1. Preferably, the outlet bin 3 and the inlet bin 2 are arranged on opposite sides. In order to better allow materials to enter the hollow cylinder 1, the bottom plate of the inlet bin 2 is arranged to be inclined.

[0024] The cover 5 is provided with a driving member 6 , and specifically, the driving member 6 at least includes a motor and a gearbox.

[0025] A transmission shaft 61 is provided at the output end of the driving member 6. The transmission shaft 61 penetrates into the hollow cylinder 1, and the bottom end is limited and fixed by a bearing seat 63; the bearing seat 63 includes a seat body and a bearing built into the seat body, and the bottom end of the transmission shaft 61 is inserted into the bearing.

[0026] The transmission shaft 61 is provided with a spiral blade 62, and the spiral blade 62 is configured as a mesh blade. The mesh size of the mesh plate 7 and the spiral blade 62 is the same. Specifically, when the mixed material enters the hollow cylinder 1, since the spiral blade 62 and the mesh plate 7 are mesh structures, the aluminum ash will fall into the processing device through the above results, and the aluminum block will be transported to the upper end by the spiral blade 62 due to its large size, and output to the external collection device through the discharge bin 3.
