A single-inlet feeding steel silo anti-segregation guiding device

Abstract

A single-inlet feeding steel silo anti-segregation guiding device is disclosed. The steel silo employs a single-inlet feeding system. A guide frame is fixedly installed below the inlet inside the silo. The guide frame includes four columns, on which a multi-layered receiving and guiding structure, evenly distributed vertically, is fixedly connected. Each receiving and guiding structure includes a U-shaped frame composed of four horizontal bars at the same horizontal height. A receiving plate is welded to the U-shaped frame, located on one side of the U-shape. The portion of the U-shape not covered by the receiving plate serves as the material outlet. In two adjacent layers of receiving and guiding structures, the lower layer's outlet corresponds to the upper layer's receiving plate. Left and right baffles, vertically oriented, are welded between the two columns at the ends of the receiving plates furthest from the outlet. The height of the left and right baffles is lower than the height between the two layers of the U-shaped frame, forming a right-angled fold with the receiving plate. This device, when installed inside the steel silo, effectively reduces material segregation.

Description

Technical Field

[0001] This utility model relates to steel silos, and in particular to a single-inlet feeding steel silo anti-segregation guiding device, belonging to the field of silo technology. Background Technology

[0002] Steel silos are used for storing various materials, such as grains and stones. During use, segregation can occur. Specifically, during material entry into the silo, differences in particle size, density, shape, and other physical properties, along with factors like airflow within the silo, lead to uneven distribution of the material, resulting in separation of coarse and fine particles, localized accumulation, or stratification. This segregation affects subsequent production processes (such as batching accuracy and product quality stability), and is particularly detrimental in industries with high requirements for material uniformity, such as chemicals, grains, and building materials. Therefore, reducing and avoiding segregation is a key issue in steel silo manufacturing. There has been considerable research on this problem, including CN222361398U (a mortar silo with an anti-segregation structure), CN220484212U (an anti-segregation silo for dry-mixed mortar production), CN218663360U (a dry-mixed mortar storage silo with an anti-segregation device), and CN213801174U. While publicly available anti-blocking and anti-segregation devices for dry-mixed mortar include mobile silos, these anti-segregation measures are primarily for mortar and involve relatively small and low-lying silos. CN221916371U discloses a novel mobile silo anti-segregation device that also provides support, which can be used in taller and larger silos. However, the anti-segregation pipe used in this device experiences material blockage during use, preventing the material from falling along the set path, resulting in poor performance. Summary of the Invention

[0003] The purpose of this invention is to overcome the problem of material segregation during the use of existing steel silos and to provide a single-inlet feeding steel silo anti-segregation guiding device.

[0004] To achieve the purpose of this utility model, the following technical solution is adopted: a single-inlet feeding steel silo anti-segregation guiding device, wherein the steel silo adopts a single-inlet feeding, the inlet is located at the top, and a guiding frame is fixedly installed below the inlet inside the steel silo. The guiding frame includes four columns, which are respectively located at the four corners of a rectangle. A multi-layer receiving and guiding structure evenly distributed vertically is fixedly connected to the four columns. The receiving and guiding structure includes a U-shaped frame, which is composed of four horizontal bars located at the same horizontal height. The two ends of the horizontal bar are welded to two adjacent columns. A receiving plate is welded to the U-shaped frame. The receiving plate is located on one side inside the U-shape and covers one-half to two-thirds of the U-shape. The part inside the U-shape not covered by the receiving plate is the material outlet. In the two adjacent material receiving and guiding structures, the material outlet of the lower layer corresponds to the material receiving plate of the upper layer. Between the two columns at the end of the receiving plate away from the material outlet, there are left and right baffles in the vertical direction. The height of the left and right baffles is lower than the height between the two U-shaped frames. The receiving plate and the left and right baffles form a right-angle fold.

[0005] Furthermore, connecting plates are welded onto adjacent columns, with the connecting plates located between two adjacent U-shaped frames.

[0006] Furthermore, right-angled side baffles are welded to both sides of the multiple right-angled folds at the top.

[0007] The positive and beneficial technical effects of this utility model are as follows: when installed in a steel silo, this device can effectively reduce the occurrence of material segregation, as detailed in the specific implementation method. Attached Figure Description

[0013] To more fully explain the implementation of this utility model, implementation examples are provided. These implementation examples are merely illustrative of this utility model and do not limit its scope.

[0014] The present invention will be further explained in detail with reference to the accompanying drawings, in which the following labels are used: 1: steel silo; 2: feed inlet; 3: column; 4: horizontal bar; 5: side baffle plate; 6: left and right baffle plates; 7: connecting plate; 8: U-shaped frame; 9: receiving plate; 10: flow outlet. It should be noted that the cross-sectional lines in the drawings are only for distinguishing between solid parts and empty parts, or for different components, and are not cross-sectional shapes.

[0015] As shown in the attached diagram, a single-inlet feeding steel silo anti-segregation guiding device is provided. The steel silo 1 adopts a single-inlet feeding method, with the inlet 1 located at the top. A guiding frame is fixedly installed below the inlet inside the steel silo 1. The guiding frame includes four columns 3, which are located at the four corners of a rectangle. A multi-layer receiving and guiding structure evenly distributed vertically is fixedly connected to the four columns. The receiving and guiding structure includes a U-shaped frame 8, which consists of four horizontal bars 4 located at the same horizontal height. Each horizontal bar is welded to two adjacent vertical columns at both ends. Connecting plates 7 are welded to the adjacent vertical columns to enhance overall stability. The connecting plates are located between two adjacent U-shaped frames. A receiving plate 9 is welded to the U-shaped frame, located inside the U-shape. The receiving plate 9 covers one-half to two-thirds of the U-shape. The portion of the U-shape not covered by the receiving plate is the material outlet 10. In the two adjacent material receiving and guiding structures, the lower material outlet corresponds to the upper material receiving plate. Figure 5 As shown, above the lower material outlet is a receiving plate. Between the two columns at the end of the receiving plate, which is away from the material outlet, are left and right baffles 6 arranged vertically. The height of the left and right baffles is lower than the height between the two U-shaped frames. The receiving plate 6 and the left and right baffles form a right-angled fold. Right-angled side baffles 5 are welded on both sides of the multiple right-angled folds at the top.

[0016] When feeding material into a steel silo using this device, most of the material falling from the inlet first lands on the top receiving plate, with a small portion falling from the flow outlet to the lower receiving plate. As the material on the receiving plate increases, a sloping material accumulation forms on the plate. When the material falls again, the material on the sloping plate falls from the flow outlet to the next layer. This process of material falling layer by layer from top to bottom continues until it reaches the bottom layer, where it spreads outwards and accumulates at the bottom of the silo to form a material pile. The material pile also acts as a guide when the material falls onto it. Because the guide frame is not fully enclosed, the space above the part of the guide frame buried by material can be used for outward flow and spreading. This device greatly reduces the velocity difference caused by the free fall of material, thus effectively overcoming the segregation phenomenon that occurs when material falls. After use, it has proven to be particularly effective in preventing segregation in steel silos used for storing grain.

[0017] After a detailed description of the embodiments of this utility model, those skilled in the art will clearly understand that various changes and modifications can be made without departing from the scope and spirit of the above-mentioned patent applications. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of this utility model shall fall within the scope of the technical solution of this utility model, and this utility model is not limited to the embodiments of the examples given in the specification.
