Description
Technical Field
[0001] The utility model relates to the technical field of raw material proportioning equipment, in particular to a raw material proportioning equipment for metal production. Background Art
[0002] The raw materials used in metal production are diverse, ranging from raw ores to processed semi-finished products. In addition to ore as the primary raw material, auxiliary raw materials such as fluxes and reducing agents are also used during the smelting process to improve smelting conditions and increase metal yield and quality. When refining alloys, raw materials containing target alloying elements are also required. Metal production uses a variety of raw materials, and the components of each raw material must be proportioned according to different needs to produce a specific metal product that meets the requirements.
[0003] The basic principle of most existing raw material proportioning equipment is to add a certain amount of various raw materials into a container and then mix them to complete the proportioning. Since the prepared raw materials are diverse and their physical properties are also different, it is also necessary to pay attention to the matching of their particle sizes to ensure the air permeability, heat transfer and reaction speed during the smelting process. The current raw material proportioning equipment lacks effective screening measures, which will lead to the presence of some raw material particles with larger particle sizes in the proportioned mixed raw materials, thereby affecting the overall smelting effect. At the same time, some raw materials may clump together. If they are not crushed, the smelting effect will be affected after mixing. Therefore, in response to the above problems, a raw material proportioning equipment for metal production is proposed. Utility Model Content
[0004] The technical problem to be solved by the present invention is to provide a raw material proportioning device for metal production, which is provided with a screening drum. After the raw materials are added thereto, the raw materials can be screened by the screening mesh plate while rotating, so that the raw materials that meet the particle size requirements fall into the proportioning and feeding mechanism for standby use. This screening method is not prone to raw material blockage. At the same time, the screening drum will also drive the raw materials to move when rotating, and the agglomerated raw materials will be broken up through the collision effect, so that the raw materials that meet the particle size requirements fall into the proportioning and feeding mechanism as much as possible. The proportioning and feeding mechanism can release a certain amount of raw materials according to the proportioning requirements, and stir and mix them through the mixing drum to complete the final proportioning work. Since the raw materials in the proportioning and feeding mechanism have been screened, the particle size adaptability is high, which is convenient for the efficient implementation of subsequent processes. It solves the technical problems in the prior art that due to the lack of effective screening measures, some raw material particles with larger particle sizes exist in the proportioned mixed raw materials, affecting the smelting effect, and the possible agglomeration of the raw materials will also affect the smelting effect.

This screening method is not prone to raw material blockage. At the same time, the screening drum 2 will also drive the raw materials to move when rotating, and the agglomerated raw materials will be broken up through the collision effect, so that the raw materials that meet the particle size requirements can fall into the proportioning and feeding mechanism 3 as much as possible. The proportioning and feeding mechanism 3 can release a certain amount of raw materials according to the proportioning requirements, and stir and mix them through the mixing barrel 4 to complete the final proportioning work.

This screening method is not prone to raw material blockage, and allows the raw materials that meet the particle size requirements to fall into the proportioning and feeding mechanism 3 as much as possible. The proportioning and feeding mechanism 3 can release a certain amount of raw materials according to the proportioning requirements, and stir and mix them through the mixing drum 4 to complete the final proportioning work. Since the raw materials in the proportioning and feeding mechanism 3 have been screened, the particle size adaptability is relatively high, which is convenient for the efficient implementation of subsequent processes.
[0042] In the above structure, since the screening mesh plate 23 is detachably connected to the drum body 21 as a whole, the screening mesh plate 23 of corresponding aperture can be replaced according to different particle size requirements, so that the overall equipment has a certain degree of applicability.
[0043] At the same time, the screening drum 2 will also drive the raw materials to move when it rotates, and the agglomerated raw materials will be broken up through the collision effect. In particular, when the drum body 21 rotates, the ridges 26 can drive part of the raw materials to move upward, and the raw materials will be thrown down when they reach a high place, which can enhance the collision effect of the raw materials and facilitate the breaking up of some agglomerated raw materials for screening.
