Novel three-layer batching bin structure for metallurgical sintering production process

Abstract

The invention discloses a novel three-layer batching bin structure for a metallurgical sintering production process. The novel three-layer batching bin structure is used in a continuous batching process of a sintering production process in the field of metallurgical industry. The novel three-layer batching bin structure is composed of an upper-layer circular-truncated-cone-shaped silo, a middle-layer cylindrical silo and a lower-layer necking structure from a circle to an inclined rectangle. The diameter of the lower end of the upper-layer circular-truncated-cone-shaped silo is larger than that of the upper end. A plurality of powder material state sensing and driving control units are mounted on the inner surface of the lower-layer circular-to-inclined rectangular necking structure and form a measurement and control array, and the powder materials in the lower layer are automatically controlled to move downwards to the inclined rectangular discharge port to be output from the microcosmic angle and the macrocosmic angle. Aiming at the production accidents such as material blockage and the like caused by material adhesion or caking because the diameter of the lower end is smaller than that of the upper end of the original batching bin which is only provided with a single inverted circular-truncated-cone-shaped silo, the novel three-layer batching bin structure solves the material adhesion and blockage problems of the original inverted circular-truncated-cone-shaped silo, so that the production accidents are avoided, and the production efficiency is improved.

Description

Technical Field

[0001] This invention relates to the technical field of large-scale process equipment for continuous sintering production in the metallurgical industry, and particularly to a novel three-layer batching silo structure for metallurgical sintering production. Background Technology

[0002] In the continuous sintering production process of the metallurgical industry, various types of powder materials are first transported by large conveyor belts to various batching silos as storage, transportation, and distribution hubs. Then, the feeders at the bottom of each batching silo control the continuous output of various materials, which are then conveyed by conveyor belts to a mixer for homogenization, resulting in a sintered mixture. Currently, the batching silos are single inverted frustum-shaped cylinders. Because the lower diameter is smaller than the upper diameter, they are very prone to material adhesion or clumping, causing blockages and other production accidents. These incidents require immediate manual intervention on-site, affecting normal production and posing certain personnel safety risks. Therefore, there is an urgent need to develop a new type of batching silo to solve these problems. Summary of the Invention

[0003] This invention discloses a novel three-layer batching silo structure for metallurgical sintering production. The novel three-layer batching silo structure consists of an upper frustum-shaped silo, a middle cylindrical silo, and a lower circular to inclined rectangular constricted structure. The purpose of this invention is to provide a batching process for continuous metallurgical sintering production that solves the problem of material sticking and clogging in the original inverted frustum-shaped silo, thereby avoiding production accidents and improving production efficiency.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A novel three-layer batching silo structure for metallurgical sintering production is disclosed, which is used in the continuous batching process of sintering production in the metallurgical industry. The novel three-layer batching silo structure consists of an upper frustum-shaped silo, a middle cylindrical silo, and a lower circular to inclined rectangular constricted structure. The lower diameter of the upper frustum-shaped silo is larger than that of the upper diameter. The inner surface of the lower circular to inclined rectangular constricted structure is equipped with a number of powder material state sensing and drive control units, which form a measurement and control array to automatically control the powder material in the lower layer to move down to the inclined rectangular discharge port from both microscopic and macroscopic perspectives.

[0006] Compared with the prior art, the beneficial technical effects of the present invention are as follows:

[0007] The lower diameter of the upper frustum-shaped silo is larger than the upper diameter. Compared with the original inverted frustum-shaped silo, this eliminates the shrinkage pressure on the powder material, which not only facilitates the downward movement of the material but also prevents material blockage. The middle cylindrical silo, acting as a buffer section, does not generate shrinkage force on the material when connecting with the lower circular interface, thus ensuring smooth material passage to the lower layer. Numerous powder material status sensing and drive control units are installed on the inner surface of the lower circular-to-inclined rectangular constriction structure, forming a measurement and control array. This array automatically controls the downward movement of the powder material in the lower layer to the inclined rectangular outlet from both microscopic and macroscopic perspectives. The measurement and control array, composed of status sensing and drive control units, effectively solves the problem of powder material adhesion and blockage during the shrinkage process. It features significant integration of electromechanical equipment and intelligent measurement and control devices, a first in this field. It offers advantages such as significant energy saving, high working efficiency, and convenient construction and installation, meeting the requirements of large-scale silo equipment. The novel three-layer batching silo structure enables automated batching without human intervention, greatly improving the efficiency and effectiveness of the batching production process, achieving significant energy-saving effects, and meeting the requirements of green, low-carbon, and high-quality development in the new era.

[0011] like Figure 1 As shown, a novel three-layer batching silo structure for a metallurgical sintering production process comprises an upper frustum-shaped silo, a middle cylindrical silo, and a lower circular-to-inclined rectangular constricted structure. The lower diameter of the upper frustum-shaped silo is larger than that of the upper diameter. The middle cylindrical silo serves as a buffer section, connecting to the lower circular interface. The lower circular-to-inclined rectangular constricted structure is designed to meet the material outlet requirements of large storage silos. To prevent material blockage caused by the contraction force of the constricted structure on the powder material, numerous powder material status sensing and drive control units are installed on the inner surface of the lower layer to control the material's downward movement to the inclined rectangular outlet.

[0012] like Figure 2 As shown, this is an enlarged schematic diagram of the lower layer in the novel three-layer batching silo structure, relative to the front view. Numerous powder material state sensing and drive control units are installed on the inner surface of the lower layer, forming a measurement and control array. This array automatically controls the powder material in the lower layer to move downwards to the inclined rectangular discharge port from both microscopic and macroscopic perspectives.

[0013] The working process of this invention is as follows:

[0014] Please see Figure 1 and Figure 2 The new three-layer batching silo structure consists of an upper frustum-shaped silo, a middle cylindrical silo, and a lower circular-to-sloping rectangular constricted structure. This design solves the problem of material sticking or clumping, which easily leads to blockages and other production accidents in the original inverted frustum-shaped silo. Specifically, the lower diameter of the upper frustum-shaped silo is larger than that of the upper silo, and the middle cylindrical silo does not exert any contraction force on the material, thus avoiding material sticking and blockages. The lower circular-to-sloping rectangular structure is a constricted structure designed to meet the material outlet requirements of large storage silos. To prevent blockages caused by contraction forces on the powder material, numerous powder material status sensing and drive control units are installed on the inner surface of the lower layer, forming a measurement and control array. This automatically controls the movement of the powder material in the lower layer to the inclined rectangular outlet from both microscopic and macroscopic perspectives. Although the production process requires each batching silo to have a large diameter and volume, the novel three-layer batching silo structure of this invention not only meets the requirements of material storage capacity for large silo volume, but also allows for control of powder materials from both microscopic and macroscopic perspectives through the measurement and control array installed in the lower layer, ensuring that the materials move down to the discharge port for smooth output.

[0015] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Various modifications and improvements made by those skilled in the art to the technical solutions of the present invention should fall within the scope of protection of the present invention.
