Description

Technical Field

[0001] This utility model relates to the field of smelting equipment technology, and in particular to a feeding pipe for smelting equipment with an internal heat insulation layer. Background Technology

[0002] Smelting equipment is the core tool of the metallurgical industry. It is mainly used to extract, purify and process metallic elements from raw materials such as ores and concentrates into metallic materials that meet industrial needs. According to the smelting object, it can be divided into ferrous metal smelting equipment and non-ferrous metal smelting equipment. Its core functions revolve around high-temperature reaction and material separation. For example, blast furnaces convert iron oxides into pig iron through high-temperature reduction reactions, while electrolysis equipment uses electrochemical principles to remove impurities from metals and improve purity. It is a key bridge connecting mineral resources and industrial metal products. Different types of smelting equipment correspond to different process paths and have significantly different technical characteristics. Pyrometallurgical smelting equipment relies on a high-temperature melting environment to complete metal extraction.

[0003] The feed pipe of smelting equipment is a key conveying component connecting the raw material storage system and the smelting main unit. Its core function is to accurately and stably transport solid raw materials such as ore, coke, and auxiliary materials to the smelting reaction area. However, it often needs to be insulated during use to prevent burns. With the advancement of technology, for feed pipes that transport ultra-high temperature raw materials, the inner layer often uses high-alumina refractory castable, which takes advantage of its excellent high-temperature resistance to directly contact the high-temperature materials. The middle layer often uses aluminosilicate fiber felt or lightweight insulating bricks, which block heat conduction and reduce heat loss through a porous structure. The outer layer uses a thin steel plate as a protective shell to prevent the insulating material from getting damp, worn, and falling off. However, this type of insulation structure has poor insulation and cannot filter out unmelted impurities inside, thus affecting product quality.

[0004] Practical content

[0005] To overcome the above shortcomings, this utility model provides a feeding pipe for smelting equipment with an internal heat insulation layer, which aims to improve the problem that the heat insulation structure in the prior art is poor and cannot filter out unmelted impurities inside, thus affecting product quality.

[0007] The filtration mechanism includes a conical tube, the top of which is connected to the bottom of the outer shell. The outer wall of the conical tube has two symmetrically distributed elongated grooves. The inner wall of the elongated grooves is slidably connected to a locking post.

[0010] As a further description of the above technical solution:

[0011] The connecting assembly includes a baffle plate, the rear side of which is fixedly connected to the outer wall of the tapered tube. The lower end of the baffle plate is provided with multiple square holes, and the inner wall of each square hole is provided with a locking block. A pull rod is connected to the front side of the locking block, and an elastic component is provided on the right side of the locking block.

[0036] Specifically, it includes a shell 1 mainly made of sturdy materials. The bottom of the shell 1 has a dedicated filter mechanism 2. The main function of the filter mechanism 2 is to efficiently filter molten slag to ensure a clean internal environment and normal equipment operation. On the inner wall of the shell 1, a heat insulation mechanism 3 is installed to effectively block high-temperature transmission and protect the shell 1 and other internal components from high-temperature damage. The filter mechanism 2 mainly consists of several parts, the core of which is a conical tube 201. The top of the conical tube 201 is tightly connected to the bottom of the shell 1, ensuring that molten slag can smoothly enter the filtration system. Two elongated grooves 202 are symmetrically formed on the outer wall of the conical tube 201. The inner walls of these two grooves 202 are fixed with locking posts 203 by a sliding connection. The design of the locking posts 203 allows them to slide flexibly within the grooves. The bottom of the locking post 203 is equipped with a special connecting component 204 for secure connection with other components. The bottom of the tapered tube 201 is equipped with a high-efficiency filter component 206, which can effectively intercept impurities in the molten slag. The connecting component 204 includes a baffle 2041. The rear side of the baffle 2041 is tightly connected to the outer wall of the tapered tube 201 by a fixed connection to ensure the stability of the structure. The lower end of the baffle 2041 is evenly provided with multiple square holes 2042. The inner wall of these square holes 2042 is penetrated by a locking block 2043. The front side of the locking block 2043 is fixed with a pull rod 2044 by a connection to facilitate operation and adjustment. In addition, the right side of the locking block 2043 is also provided with an elastic component 205, which can provide necessary elastic support when the locking block 2043 moves to ensure that the connection between the components is tight and reliable.

[0038] Specifically, the heat insulation mechanism 3 is composed of multiple parts, mainly including a filling layer 301. The outer wall of the filling layer 301 is tightly connected to the inner wall of the outer shell 1, ensuring the overall stability of the heat insulation mechanism 3. Inside the filling layer 301, a core heat insulation layer 302 is specially provided, which plays a key role in heat insulation. In order to further improve the heat insulation effect, multiple equally spaced annular gaps 303 are opened on the inner wall of the core heat insulation layer 302. The design of these gaps helps to evenly distribute and effectively block heat. In addition, an anti-stick inner layer 304 is also fixedly connected to the inner wall of the core heat insulation layer 302 to prevent the heat insulation material from sticking together during use, and further improve the durability and service life of the heat insulation layer. In order to protect the overall structure of the heat insulation mechanism 3, multiple protective components 305 are provided at the upper and lower ends of the outer shell 1. Each protective component 305 specifically includes an annular groove 3051. These annular grooves 3051 are respectively opened at the upper and lower ends of the filling layer 301. The inner wall of the annular groove 3051 is connected to the retaining ring 3052 by a sliding connection, which ensures that the retaining ring 3052 can move flexibly in the groove. The outer side of the retaining ring 3052 is connected to a protective layer 3053. This protective layer 3053 not only enhances the overall protection capability of the heat insulation mechanism 3, but also prevents external factors from damaging it to a certain extent, ensuring the stable operation of the heat insulation mechanism 3 in various environments.

[0039] Please see the appendix Figure 1 Appendix Figure 5 and attached Figure 6 The elastic component 205 includes a sliding rod 2051, the outer wall of which is slidably connected to the right side of the locking block 2043. A spring 2052 is provided on the outer wall of the sliding rod 2051. A connecting plate 2053 is connected to the outer side of the sliding rod 2051. The filter component 206 includes a filter plate 2061, the outer wall of which is slidably connected to the inner wall of the tapered tube 201. Multiple filter holes 2062 are provided at the bottom of the filter plate 2061.

[0040] Specifically, the elastic component 205 consists of the following parts: a sliding rod 2051, the outer wall of which forms a sliding connection with the right side of the locking block 2043 to ensure smooth relative movement between them; a spring 2052, which provides the necessary elastic force to ensure the normal operation of the entire component; and a connecting plate 2053 connected to the outer side of the sliding rod 2051. The function of 53 is to effectively connect the sliding rod 2051 with other components, thereby enhancing the stability of the overall structure. In addition, the filter assembly 206 includes a filter plate 2061, the outer wall of which is slidably connected to the inner wall of the conical tube 201, allowing the filter plate 2061 to move flexibly inside the conical tube 201. At the bottom of the filter plate 2061, multiple filter holes 2062 are evenly opened. The main function of these filter holes 2062 is to allow fluid to pass through while effectively intercepting impurities, thereby achieving the purpose of filtration.

[0041] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 3 The inner part of the outer shell 1 is provided with a spiral guide groove 4 for guiding the material feeding. A threaded cylinder 5 is fixedly connected to the top of the outer shell 1. A sealing ring 6 is provided on the top of the outer shell 1. The inner wall of the sealing ring 6 is slidably connected to the outer wall of the threaded cylinder 5.

[0042] Specifically, the outer shell 1 has a spiral guide channel 4 inside, which is specially designed to guide the material feeding process. The spiral guide channel 4, through its unique spiral structure, can effectively guide the material to fall smoothly along a predetermined path. A threaded cylinder 5 is fixedly connected to the top of the outer shell 1. The threaded cylinder 5 is tightly connected to the outer shell 1 through a robust connection method, ensuring the stability and reliability of the overall structure. In addition, a sealing ring 6 is specially provided on the top of the outer shell 1. The main function of the sealing ring 6 is to ensure the sealing performance of the top of the outer shell 1, prevent external impurities from entering and internal material from leaking. The inner wall of the sealing ring 6 and the outer wall of the threaded cylinder 5 adopt a sliding connection method, which ensures a tight fit between the two and also allows the threaded cylinder 5 to slide within a certain range, thereby adapting to different working requirements.

[0043] Working principle: First, pull rod 2044 is pulled outward. At this time, pull rod 2044 will drive the locking block 2043 to move. The locking block 2043 will then leave the inner wall of the square hole 2042 of baffle 2041. The locking block 2043 will then move along sliding rod 2051. At this time, spring 2052 will be compressed, and filter plate 2061, along with locking post 203, will be locked back into the long groove 202 of tapered tube 201. Then, release pull rod 2044, so that locking block 2043 locks locking post 203. At this time, when feeding, the internal liquid will be filtered through the filter hole 2062 of filter plate 2061, separating the incompletely melted part. When filter plate 2061 is full and filter hole 2062 is blocked, filter plate 2061 can be removed and cleaned in the same way. This achieves the function of filtering out the incompletely melted part, improving product quality, and cleaning filter plate 2061 at the same time.

[0044] There is a filling layer 301 on the inner side of the outer shell 1. The filling layer 301 is made of fiber cotton and can keep the heat while providing insulation. There are annular grooves 3051 at the upper and lower ends of the filling layer 301, which can hold the protective layer 3053 with the retaining ring 3052 inside to protect the internal materials. There is a core heat insulation layer 302 inside the filling layer 301. An annular gap 303 is opened on the inner side of the core heat insulation layer 302 to prevent the core heat insulation layer 302 from expanding due to overheating and causing damage. This realizes the function of feeding the smelted liquid and keeping it warm.

[0045] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
