Description

Technical Field

[0001] The utility model relates to the technical field of side-blown reduction smelting furnaces, in particular to an automatic charging device for a side-blown reduction smelting furnace. Background Art

[0002] The side-blowing reduction smelting furnace is a widely used equipment in the metal smelting industry. It introduces reducing gas during the smelting process to promote the reduction reaction of metals or ores, thereby extracting high-purity metals. This smelting method has the advantages of low energy consumption, high efficiency, and simple operation, so it has been widely used in the steel, non-ferrous metals and other industries.

[0003] However, the traditional side-blown reduction smelting furnace has some shortcomings in the charging process. First, the traditional charging method mostly relies on manual operation, which is not only inefficient, but also difficult to ensure the accuracy and consistency of each charging, which easily leads to fluctuations in the smelting process and affects product quality. Secondly, manual charging also has safety hazards. Operators need to work in a high temperature environment, which increases the risk of industrial accidents.

[0004] Although the existing automatic feeding device of the side-blown reduction smelting furnace has solved the problem of manual feeding to a certain extent, it still has some shortcomings. For example, some automatic feeding systems are not efficient enough in pre-mixing materials, resulting in uneven mixing of materials entering the smelting furnace, affecting the smelting effect. In addition, the material transportation of some devices is not continuous enough, which may cause interruptions in the smelting process and affect production efficiency. Utility Model Content

[0039] See also Figure 1-4 , an automatic charging device for a side-blown reduction smelting furnace, comprising:

[0040] Melting furnace 1

[0041] The smelting furnace 1 is a container with high temperature tolerance, which is used for reduction smelting of metal or ore. Its top charging port is designed to be circular, which is convenient for the installation of the charging hopper 2 and the smooth inflow of materials.

[0042] Hopper 2

[0043] The feeding hopper 2 is a funnel-shaped structure. The spiral feeding shaft 3 is located at the center of the feeding hopper 2 and is driven by a reduction motor 4 to achieve continuous conveying and quantitative control of materials.

[0044] Premix tank 5

[0045] The bottom closed seat 51 is a solid base, and a driving motor 53 is installed inside the bottom closed seat 51 for driving the homogenizing rotary table 54 to rotate.

[0046] The mixing cylinder 52 is a cylindrical structure that can slide up and down. When it moves upward, the bottom sealing seat 51 and the homogenizing rotary table 54 are exposed. At this time, the mixed additives fall evenly to the inside of the feeding hopper 2 at the edge of the bottom sealing seat 51 due to their own weight.

[0047] The top of the homogenizing rotary table 54 is designed to be in the shape of an arc, which helps to evenly distribute and mix the materials during the rotation process. This design also makes it easier for the added materials deposited on the top of the mixing cylinder 52 to slide down when the mixing cylinder 52 is lifted off its top.

[0048] Top platform 6 and unloading drive mechanism 7

[0049] The top platform 6 is a platform structure, which is firmly connected to the smelting furnace 1 through the support 11, providing sufficient space and supporting force.

[0050] The electric telescopic rod 71 in the material discharge driving mechanism 7 is installed at the center of the top platform 6, and is connected to the upper port of the mixing cylinder 52 through the connecting platform 72 and the connecting column 73, so as to realize the precise control of the position of the mixing cylinder 52 and the operation of lifting and lowering the mixing cylinder 52.

[0051] Hoist 8

[0052] The elevators 8 are distributed on four sides of the smelting furnace 1, and the discharge end of each elevator is precisely aligned with the top of the homogenizing rotary table 54 to ensure that the material can fall into the pre-mixing tank 5 accurately and undergo a homogenizing operation.

[0053] Support structure

[0054] The support pillars 11 are strong supporting rods that ensure a stable connection between the top platform 6 and the smelting furnace 1 .

[0055] The oblique support rod 21 extends from the bottom of the bottom closure seat 51 to the upper end of the hopper 2 to provide additional support and stability.

[0056] How it works

[0057] Premixing of materials

[0058] The different additives are lifted to the top of the premixing tank 5 by the elevators 8 around it, and then evenly distributed in the mixing cylinder 52 .

[0059] The driving motor 53 is started to drive the homogenizing rotary table 54 to rotate, and the materials are efficiently premixed in the premixing tank 5 by utilizing its arc top design.

[0060] Material unloading

[0061] The electric telescopic rod 71 is started, and the upward movement of the mixing barrel 52 is accurately controlled by the connecting platform 72 and the connecting column 73. At this time, the mixed various additives fall evenly to the inside of the feeding hopper 2 at the edge of the bottom closed seat 51 due to their own weight.

[0062] Spiral feeding

[0063] The spiral feeding shaft 3 is driven by a reduction motor 4 , and through the design of its spiral blades, the mixed additives are quantitatively guided from the inside of the feeding hopper 2 to the smelting furnace 1 .

[0064] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.

[0065] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
