Description

Technical Field

[0001] The utility model relates to the technical field of iron and steel metallurgy, and in particular to a secondary distribution device for sintered ore. Background Art

[0002] The sintering process proceeds from top to bottom, requiring more fuel in the upper portion of the material bed and less in the lower portion. Therefore, split fuel addition technology is an important method for optimizing fuel usage during the sintering process. This split fuel addition not only reduces fuel consumption but also improves sintering efficiency.

[0003] The existing fuel distribution technology usually opens an opening at the bottom of the silo and lets the fuel fall onto the sintering car by gravity. However, in actual use, it cannot achieve uniform distribution and easily affects the heat transfer efficiency. Utility Model Content

[0004] The utility model provides a sintered ore secondary distribution device, which solves the problem of uneven secondary distribution in the related art.

[0005] The technical solution of the utility model is as follows:

[0006] A secondary sintering ore distribution device is used for secondary distribution of sintered ore onto a trolley, comprising:

The cloth shaft has a plurality of holding grooves, and the plurality of holding grooves are spaced apart along the circumferential direction of the cloth shaft. The holding grooves are used to hold the material in the silo. After the cloth shaft rotates, the material in the holding grooves falls to the first discharge port.

[0010] Optionally, the circumferential surface of the material distribution shaft is rotatably sealed to the inner wall of the silo.

[0013] Optionally, it also includes:

[0014] A rotating roller is rotatably mounted on the bracket, wherein the rotating axis of the rotating roller is parallel to the rotating axis of the material distribution shaft, and the hopper and the rotating roller are sequentially distributed along the forward direction of the trolley;

[0015] There are several breaking rods, all of which are arranged on the rotating roller. The several breaking rods are distributed along the circumference of the rotating axis of the rotating roller. The breaking rods are used to break up the materials on the upper surface of the trolley.

[0016] Optionally, it also includes:

[0017] A connecting rod is provided at one end of the bracket close to the trolley, and the hopper, the rotating roller and the connecting rod are sequentially distributed along the forward direction of the trolley;

A distribution shaft is rotatably mounted within the silo, with its axis of rotation perpendicular to the forward direction of the trolley. The distribution shaft has a plurality of receiving slots distributed along its circumference.

[0026] During operation, the silo stores material to be distributed. As the distribution shaft rotates, the material in the silo falls into various holding troughs. As the shaft continues to rotate, when the holding troughs reach the first discharge port, the material in the troughs falls out of the first discharge port, distributing the material onto the trolley. The uniform rotation of the distribution shaft and the even distribution of the multiple holding troughs ensure a relatively uniform amount of material each time it falls from the first discharge port, effectively solving the problem of uneven secondary distribution.

It improves the quality and output of sintered ore while reducing energy consumption. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0034] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the specific implementation methods of the present invention will be described below with reference to the accompanying drawings. Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without inventive work.

[0035] To simplify the drawings, only the parts relevant to the utility model are schematically shown in each figure; they do not represent the actual structure of the product. Furthermore, to simplify the drawings and facilitate understanding, in some figures, only one of the components with the same structure or function is schematically shown or labeled. In this document, "one" not only means "only one" but also "more than one," and "several" includes "two" and "more than two."

[0036] It should be noted that, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they can refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0037] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0038] Reference Figures 1 to 4 The utility model proposes a secondary distribution device for sintered ore, which is used for secondary distribution to the trolley 100, including a hopper 300 arranged on a bracket 200, the hopper 300 is located above the trolley 100, and the bottom of the hopper 300 is provided with a first discharge port 310; a distribution shaft 400 is rotatably arranged in the hopper 300, and the rotation axis of the distribution shaft 400 is perpendicular to the forward direction of the trolley 100, and the distribution shaft 400 has a plurality of holding grooves 410, and the plurality of holding grooves 410 are distributed at intervals along the circumferential direction of the distribution shaft 400, and the holding grooves 410 are used to hold the material in the hopper 300. After the distribution shaft 400 rotates, the material in the holding grooves 410 falls to the first discharge port 310.

[0039] In this embodiment, the device includes a silo 300 mounted on a support 200, located directly above the trolley 100. A first discharge port 310 is provided at the bottom of the silo 300. A distribution shaft 400 is rotatably mounted within the silo 300, with its axis of rotation perpendicular to the direction of travel of the trolley 100. The distribution shaft 400 has a plurality of receiving slots 410 distributed along its circumference.

[0040] During operation, the silo 300 stores material to be distributed. As the distribution shaft 400 rotates, the material within the silo 300 falls into the various receiving slots 410. As the distribution shaft 400 continues to rotate, when the receiving slots 410 reach the first discharge port 310, the material within the slots 410 falls from the first discharge port 310, distributing the material onto the trolley 100. The uniform rotation of the distribution shaft 400 and the even distribution of the multiple receiving slots 410 ensure a relatively uniform amount of material each time it falls from the first discharge port 310, effectively resolving the issue of uneven secondary distribution.

[0041] In this way, the material can be more evenly distributed on the trolley 100, improving the material distribution during the sintering process and optimizing the sintering effect. Compared with traditional material distribution methods, this device greatly improves material distribution uniformity and reduces the impact of uneven material height on the trolley 100 due to uneven distribution, which can affect thermal utilization. This improves the quality and output of sintered ore while reducing energy consumption.

[0042] It should be further explained that the error between the length of the holding groove 410 along the rotation axis of the distribution shaft 400 and the width of the trolley 100 should not be greater than ±50 mm, which is more conducive to ensuring uniform distribution of the distribution shaft 400 on the trolley 100.

[0043] Furthermore, the circumferential surface of the material distribution shaft 400 is rotatably sealed to the inner wall of the silo 300 .

[0044] In this embodiment, this sealed connection is typically made of a wear-resistant material with excellent sealing properties, such as a rubber seal or packing. The seal or packing is installed where the inner wall of the silo 300 contacts the circumference of the distribution shaft 400. When the distribution shaft 400 rotates, it fits tightly against the distribution shaft 400, effectively preventing material from leaking through the gap between the two.

[0045] Through such a rotary sealing connection, during the continuous rotation of the material distribution shaft 400 to perform material distribution operations, the material in the silo 300 is always strictly confined to a predetermined flow path, and uneven distribution or material waste will not occur due to leakage through gaps.

[0046] Furthermore, it also includes a spiral feeding rod 500, which is rotatably arranged in the silo 300. The spiral feeding rod 500 is located above the cloth shaft 400. The rotation axis of the spiral feeding rod 500 is parallel to the rotation axis of the cloth shaft 400. The spiral feeding rod 500 has a spiral auger. The spiral feeding rod 500 is used to guide the material in the silo 300 from one end to the other end.

[0047] In this embodiment, the spiral feed rod 500 rotates, and the spiral auger pushes the material in the silo 300 from one end to the other. The spiral feed rod 500 allows workers to add material at one end of the silo 300 instead of distributing the material evenly along the axis of the distribution shaft 400, reducing the operator's labor intensity.

[0048] Moreover, the spiral feeding rod 500 helps to distribute the material more evenly in the silo 300 , thereby preventing local accumulation of the material in the silo 300 .

[0049] Furthermore, it also includes: a rotating roller 610 is rotatably set on the bracket 200, the rotation axis of the rotating roller 610 is parallel to the rotation axis of the cloth shaft 400, and the hopper 300 and the rotating roller 610 are distributed in sequence along the forward direction of the trolley 100; there are several breaking rods 620, all of which are set on the rotating roller 610, and the several breaking rods 620 are distributed circumferentially along the rotation axis of the rotating roller 610, and the breaking rods 620 are used to break up the material on the upper surface of the trolley 100.

[0050] In this embodiment, a plurality of breaking rods 620 are provided on the rotating roller 610 , and the breaking rods 620 are distributed along the circumference of the rotating axis of the rotating roller 610 .

[0051] During operation, the material storage slots 410 on the material distribution shaft 400 are arranged at intervals, so the material on the upper surface of the trolley 100 appears as long, strip-shaped protrusions. As the trolley 100 advances, it passes under the rotating rollers 610. At this time, the rotating rollers 610 rotate, driving the breaking rods 620 to rotate. The breaking rods 620 can break up the material accumulated on the upper surface of the trolley 100, making it more evenly distributed.

[0052] This breaking up operation further improves the distribution of the materials on the trolley 100 , avoids local accumulation and agglomeration of the materials, and provides more ideal material distribution conditions for the subsequent sintering process.

[0053] Furthermore, it also includes: a connecting rod 710 is arranged at one end of the bracket 200 close to the trolley 100, and the hopper 300, the rotating roller 610, and the connecting rod 710 are distributed in sequence along the forward direction of the trolley 100; the flat material shaft 720 is arranged at one end of the connecting rod 710 close to the trolley 100, and the flat material shaft 720 is used to smooth the material on the surface of the trolley 100.

[0054] In this embodiment, during operation, after the material is broken up by the breaking rod 620, the trolley 100 continues to advance. When it reaches the leveling shaft 720, the leveling shaft 720 smoothes the material on the surface of the trolley 100. The leveling shaft 720 can smooth out any uneven material surface, making the material distribution on the trolley 100 more even and smooth.

[0055] Through the action of the flat material shaft 720 , the distribution state of the material on the trolley 100 is further optimized, creating more favorable conditions for the subsequent sintering process and improving the quality and efficiency of sintering.

[0056] Furthermore, it also includes: an electronic belt scale 810 is set on the bracket 200, the electronic belt scale 810 is located above the silo 300, and the electronic belt scale 810 is used to transport materials to one end of the silo 300.

[0057] In this embodiment, during operation, the electronic belt scale 810 can precisely control the amount of material delivered to one end of the silo 300. Through its precise metering and delivery functions, it can accurately provide the required amount of material to the silo 300 according to actual production needs, thereby better ensuring the stability and uniformity of the entire material distribution process.

[0058] Furthermore, it also includes: a buffer bin 820 is arranged on the bracket 200, and a second discharge port 821 is provided at the bottom of the buffer bin 820, and the buffer bin 820 is located above the electronic belt scale 810; a flat gate valve 830 is arranged at the second discharge port 821, and the flat gate valve 830 is used to open or close the second discharge port 821.

[0059] In this embodiment, in actual operation, the material first enters the buffer bin 820 for temporary storage. When the material needs to be transported to the electronic belt scale 810, the second discharge port 821 is opened by controlling the flat gate valve 830 to allow the material to smoothly fall into the electronic belt scale 810.

[0060] The buffer bin 820 can buffer and regulate the material supply. For example, when the material supply fluctuates or is unstable, the buffer bin 820 can store a certain amount of material to ensure that the material delivery to the electronic belt scale 810 is relatively stable.

[0061] The flat gate valve 830 can flexibly control the opening and closing of the second discharge port 821, thereby achieving precise control over the material output, and further ensuring the stable operation of the entire material distribution system and the uniformity of the material distribution.

[0062] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, and all of these should be included in the scope of the claims of the present invention.
