The Al (aluminum) content in bauxite is between 95% and 97%, and it also contains a small amount of Fe (iron), Si (silicon), Ti (titanium), etc. Therefore, it is necessary to use bauxite, carbon material, and iron filings as three raw materials to melt, reduce and purify in an electric arc furnace to obtain brown artificial corundum.
[0003] In the prior art, a Chinese patent document with the announcement number CN 205361245 U discloses a raw material batching device for producing corundum, including a group of feeding boxes arranged in parallel, each of which is used to store corresponding raw materials, a feeding port is provided on the lower side of each feeding box, a discharging device is connected to the feeding port of each feeding box, each of which is connected to a filter screen device, and a weighing device is matched and connected to the lower side of each filter screen device, and a first feeding device is correspondingly connected to the lower side of the weighing device, and a mixing device is connected to one side of the first feeding device through a feeding pipe, and a second feeding device is matched to the lower side of the mixing device. The above scheme realizes the proportioning through the weighing device, and then realizes the mixing through the mixing device, so the efficiency of proportioning and mixing is low, and although the weighing device has a more accurate proportioning, in the production site of corundum, which has a lot of dust and a huge daily proportioning mass, the dust is extremely easy to cause the weighing device to malfunction, and the fatigue strength is large and it is easy to be damaged, resulting in production suspension and low efficiency.

[0023] Example:
[0024] like Figure 1 and Figure 2 As shown: a mixing mechanism for corundum smelting and purification, is provided with a mounting frame 1, a mixing and conveying mechanism 2 is installed on the mounting frame 1, and raw material conveying units 3 are respectively arranged above the mixing and conveying mechanism 2. The raw material conveying unit 3 includes three raw material conveying mechanisms. The raw material conveying mechanisms have different conveying rates, which are adjusted according to the production ratio. A feeding and smoothing shell 4 is installed on the raw material conveying mechanism, which is used to smooth the conveyed raw materials on the raw material conveying mechanism to the same height, so that the raw materials are spread more evenly on the raw material conveying mechanism. Therefore, by adjusting the different conveying rates of each raw material conveying mechanism, a faster proportion of corundum purification raw materials is achieved, and the raw materials conveyed by each raw material conveying mechanism all fall onto the mixing and conveying mechanism 2 for mixing, and are conveyed to the furnace for reduction and purification to obtain brown corundum. Its mechanical proportioning and mixing equipment is not easy to be damaged and has high production efficiency.
[0025] The above-mentioned mixed conveying mechanism 2 is provided with a driving mechanism 21, a driving roller 22, a driven roller 23 and a conveyor belt 24. The output end of the driving mechanism 21 is connected to the driving roller 22. The driving roller 22 and the driven roller 23 are rotatably mounted on the two ends of the mounting frame 1 respectively. The conveyor belt 24 is sleeved between the driving roller 22 and the driven roller 23, and the driving roller 22 is arranged at the unloading end of the conveyor belt 24.
[0026] A support roller structure 25 is also evenly arranged on the mounting frame 1. The support roller structure 25 is evenly arranged at the bottom of the conveying surface of the conveyor belt 24. The support roller structure 25 includes a left oblique support frame 251, a right oblique support frame 252, a left support roller 253 and a right support roller 254. The left oblique support frame 251 and the right oblique support frame 252 are arranged on the mounting frame 1, and the left support roller 253 and the right support roller 254 are respectively obliquely installed on the left oblique support frame 251 and the right oblique support frame 252. The left support roller 253 and the right support roller 254 are relatively inclined downward. Therefore, the conveying surface of the conveyor belt 24 collapses downward under the heavy pressure of the raw materials, and is supported by the left support roller 253 and the right support roller 254 to prevent the raw materials from falling to the edge, and does not affect the normal conveying work of the conveyor belt 24. The friction force is relatively small, so the required driving force is smaller.
[0027] The above-mentioned raw material conveying unit 3 includes three raw material conveying mechanisms, namely the first raw material conveying mechanism 31, the second raw material conveying mechanism 32 and the third raw material conveying mechanism 33. More raw material conveying mechanisms can be set, but it is generally not necessary. The first raw material conveying mechanism 31, the second raw material conveying mechanism 32 and the third raw material conveying mechanism 33 are arranged in sequence above the mixing conveying mechanism 2, and the first raw material conveying mechanism 31 is used to convey carbon materials, the second raw material conveying mechanism 32 is used to convey iron filings, which are waste iron filings in the manufacturing industry, and the third raw material conveying mechanism 33 is used to convey alumina, and both are conveyed to the conveyor belt 24 of the mixing conveying mechanism 2. This arrangement is conducive to mixing. Carbon materials are generally coal, which are in block form and powder form. Therefore, after the iron filings are added in the middle, they can be more fully mixed after being squeezed by the alumina blocks. Since the alumina blocks are the main raw materials and the amount required to be added is large, an additional raw material conveying mechanism can be set to convey alumina.
[0028] The first raw material conveying mechanism 31 is provided with a first support frame, a first driving mechanism, a first active roller, a first driven tensioning roller and a first conveyor belt. The output end of the first driving mechanism is connected to the first active roller. The first active roller and the first driven tensioning roller are rotatably mounted on both ends of the first support frame respectively. The first conveyor belt is sleeved between the first active roller and the first driven tensioning roller, and the first active roller is arranged at the unloading end of the first conveyor belt. The first support frame can be connected to the mounting frame 1 or be independently arranged. The same is true for other raw material conveying mechanisms.
[0029] The above-mentioned second raw material conveying mechanism 32 and third raw material conveying mechanism 33 have the same structure as the first raw material conveying mechanism 31, and guardrail plates are arranged on the mounting frame 1, and the guardrail plates are located on both sides of the conveyor belt 24, and reinforced inclined guardrail plates 11 are arranged below the unloading ends of the second raw material conveying mechanism 32 and the third raw material conveying mechanism 33. The reinforced inclined guardrail plates 11 are symmetrically arranged on both sides of the conveyor belt 24 to prevent the iron filings or alumina conveyed by them from being scattered to other places, causing waste and inaccurate proportions. The below the unloading end of the first raw material conveying mechanism 31 can also be used, but because the first raw material conveying mechanism 31 is located at the front, there are no other raw materials on the conveyor belt 24, and the carbon material is neither light nor heavy, so it is not easy to be scattered to other places.
[0030] A feeding interface 5 is provided at the top of the feeding and smoothing shell 4. The feeding and smoothing shell 4 is provided with an oblique buffer portion and a scraper portion. The oblique buffer portion and the scraper portion are located above the discharge portion of the feeding and smoothing shell 4, and the scraper portion is connected to the lowest end of the oblique buffer portion. The scraper portion is used to smooth the conveyed raw materials to the same height, and the oblique buffer portion is used to avoid the jam of the raw materials, so that the smoothed raw materials have room to move, and it is beneficial for the raw materials to move to the edge gap. The scraper portion is arranged in the middle of the conveyor belt near the discharge end, and a section is exposed to facilitate observation of whether the proportioning discharge is blocked.
[0031] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention shall be defined by the appended claims.
