A structure for enhancing the compressive strength of high-sulfur ore pellets

Abstract

This utility model discloses a structure for enhancing the compressive strength of high-sulfur ore pellets, relating to the field of high-sulfur ore pellet technology. It includes a first protective shell, with a second protective shell located on the right side of the first protective shell. Handles are fixedly connected to the outer walls of both the first and second protective shells. Several first springs are fixedly connected to the inside of each of the first and second protective shells. By setting the first and second protective shells outside the pellet and configuring protective covers and elastic plates inside, a multi-layered buffer structure is formed.

Description

Technical Field

[0001] This utility model relates to the field of high-sulfur ore pellets, and in particular to a structure for enhancing the compressive strength of high-sulfur ore pellets. Background Technology

[0002] In recent years, China's dependence on imported iron ore has been increasing, while global iron ore resources have been deteriorating. Given the diversity of iron ore raw materials in nature, the differences in mining and beneficiation technologies, and the complexity of blast furnace smelting conditions, it is both necessary and urgent to conduct a more systematic and detailed study of the impact of iron-bearing raw materials containing certain special elements on the process parameters and performance of pellets. Wanli iron concentrate produced by Liaoyang Wanli Mining Co., Ltd. is a high-sulfur, high-magnesium, and low-silicon alkaline magnetite concentrate, with a sulfur content of 4.87% and an MgO content of 3.05%. The total iron grade of Wanli iron concentrate is lower than that of Liaoyang Jinhe, Anshan Iron and Steel Group Daci, and Anshan Qianhai iron concentrates. During blast furnace smelting, MgO is a beneficial element that can improve the viscosity, flowability, and sulfur capacity of blast furnace slag, making it an indispensable component in the slag-forming process. However, due to its high sulfur content, it inhibits the oxidation of pellets during roasting, reducing the compressive strength of the finished pellets.

[0003] Pellets (especially iron ore pellets) are subjected to external forces such as collision, compression, and friction during transportation and storage. If they are not protected, they are prone to breakage and pulverization. Therefore, it is necessary to protect the pellets. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a structure for enhancing the compressive strength of high-sulfur ore pellets, thus solving the problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a high-sulfur ore pellet compressive strength enhancement structure, including a first protective shell, a second protective shell provided on the right side of the first protective shell, handles fixedly connected to the outer walls of the first and second protective shells respectively, one end of a plurality of first springs fixedly connected to the inside of the first and second protective shells respectively, a protective cover fixedly connected to the other end of the plurality of first springs, and an elastic plate fixedly connected to the inner wall of the plurality of protective covers.

[0006] As a further technical solution of this utility model, the number of the first spring, protective cover and elastic plate is eight, and the eight first springs, protective covers and elastic plates are arranged in a circle inside the first protective shell and the second protective shell.

[0007] As a further technical solution of this utility model, eight protective covers and elastic plates are spherically arranged inside the first and second protective shells. The high-sulfur ore pellets are arranged inside the eight protective covers and elastic plates, and the pellets are placed within the spherical protective space formed by the eight protective covers and elastic plates. The protective covers are connected to the first and second protective shells via a first spring, and the elastic plates are fixed to the inner wall of the protective covers. When the pellets are subjected to external forces (such as collisions or compression), the elastic plates first contact the pellets and undergo elastic deformation, absorbing part of the impact force. Subsequently, the protective covers move backward under the action of the first spring, further dispersing and buffering the impact force. This multi-layer buffering mechanism can effectively reduce the direct impact force on the pellets, prevent the pellets from breaking or pulverizing, and thus significantly improve the compressive strength of the pellets.

[0008] As a further technical solution of this utility model, a sliding hole is provided inside the first protective shell, and an abutment block is fixedly connected to the left side of the second protective shell, the abutment block being disposed inside the sliding hole.

[0009] As a further technical solution of this utility model, a vertical hole is provided inside the first protective shell, the vertical hole is connected to a sliding hole, and a rod is slidably connected inside the sliding hole, the rod abutting against the left side of the abutting block.

[0010] As a further technical solution of this utility model, a connecting groove is provided inside the first protective shell, and a connecting plate is slidably connected inside the connecting groove.

[0011] As a further technical solution of this utility model, the connecting plate is fixedly connected to the insert rod, and a second spring is fixedly connected between the connecting plate and the inner wall of the connecting groove. The abutment block of the second protective shell is aligned with the sliding hole of the first protective shell and inserted into the sliding hole, so that the first protective shell and the second protective shell are initially aligned. When the abutment block abuts the insert rod, the insert rod moves upward. When the abutment block moves to the leftmost position, the insert rod disengages from the abutment block and is reset under the action of the second spring, thereby achieving the limitation of the abutment block. When it is necessary to remove the ball, the insert rod is pulled by external force to disengage from the left side of the abutment block, thereby releasing the lock. The first protective shell and the second protective shell can be quickly separated to expose the ball inside for easy removal.

[0012] This invention provides a structure for enhancing the compressive strength of high-sulfur ore pellets, which has the following advantages compared with the prior art:

[0013] 1. This design presents a high-sulfur ore pellet compressive strength enhancement structure. By setting a first and second protective shell on the outside of the pellet, and configuring a protective cover and elastic plate inside, a multi-layered buffer structure is formed. When the pellet is subjected to external force, the first spring and elastic plate can effectively absorb and disperse the impact force, preventing the pellet from breaking or pulverizing due to collision or compression, thereby significantly improving the compressive strength of the pellet. The eight protective covers and elastic plates are evenly distributed in a spherical shape, providing all-round protection for the pellet and ensuring a stable buffering effect in all directions.

[0014] 2. This design provides a structure to enhance the compressive strength of high-sulfur ore pellets. The first and second protective shells are connected by components such as sliding holes, contact blocks, insert rods, connecting grooves, and a second spring, enabling rapid disassembly of the first and second protective shells for easy removal of the internal pellets. This rapid disassembly and assembly mechanism significantly reduces operation time and improves work efficiency. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4This utility model provides a technical solution for enhancing the compressive strength of high-sulfur ore pellets: A high-sulfur ore pellet compressive strength enhancement structure includes a first protective shell 1, a second protective shell 2 disposed on the right side of the first protective shell 1, handles 3 fixedly connected to the outer walls of the first protective shell 1 and the second protective shell 2, one end of several first springs 4 fixedly connected to the inside of the first protective shell 1 and the second protective shell 2, the other end of several first springs 4 fixedly connected to protective covers 5, and elastic plates 6 fixedly connected to the inner walls of several protective covers 5. The number of first springs 4, protective covers 5, and elastic plates 6 is eight. The eight first springs 4, protective covers 5, and elastic plates 6 are arranged circumferentially inside the first protective shell 1 and the second protective shell 2, and the eight protective covers 5 and elastic plates 6 are arranged spherically inside the first protective shell 1 and the second protective shell 2. The high-sulfur ore pellets are placed inside the eight protective covers 5 and elastic plates 6, and the pellets are placed in the spherical protective space formed by the eight protective covers 5 and elastic plates 6. The protective cover 5 is connected to the first protective shell 1 and the second protective shell 2 via a first spring 4. The elastic plate 6 is fixed to the inner wall of the protective cover 5. When the pellets are subjected to external forces such as collisions or compression, the elastic plate 6 first contacts the pellets and undergoes elastic deformation, absorbing part of the impact force. Subsequently, the protective cover 5 moves backward under the action of the first spring 4, further dispersing and buffering the impact force. This multi-layer buffering mechanism can effectively reduce the direct impact force on the pellets, prevent the pellets from breaking or pulverizing, and thus significantly improve the compressive strength of the pellets.

[0022] like Figure 4 As shown, the first protective shell 1 has a sliding hole 7 inside, and the left side of the second protective shell 2 is fixedly connected to an abutment block 8, which is disposed inside the sliding hole 7. The first protective shell 1 has a vertical hole 9 inside, which communicates with the sliding hole 7. An insertion rod 10 is slidably connected inside the sliding hole 7, and the insertion rod 10 abuts against the left side of the abutment block 8. The first protective shell 1 has a connecting groove 11 inside, and a connecting plate 12 is slidably connected inside the connecting groove 11. The connecting plate 12 is fixedly connected to the insertion rod 10, and a second spring 13 is fixedly connected between the connecting plate 12 and the inner wall of the connecting groove 11, thereby securing the second protective shell 2. The abutment block 8 is aligned with the sliding hole 7 of the first protective shell 1 and inserted into the sliding hole 7, so that the first protective shell 1 and the second protective shell 2 are initially aligned. When the abutment block 8 abuts the insertion rod 10, the insertion rod 10 moves upward. When the abutment block 8 moves to the leftmost position, the insertion rod 10 disengages from the abutment block 8 and is reset under the action of the second spring 13, thereby limiting the abutment block 8. When it is necessary to remove the ball, the insertion rod 10 is pulled by external force to disengage from the left side of the abutment block 8, releasing the lock. The first protective shell 1 and the second protective shell 2 can be quickly separated to expose the ball inside, making it easy to remove.

[0023] The working principle of this invention is as follows: The pellet is placed within a spherical protective space consisting of eight protective covers 5 and elastic plates 6. The protective covers 5 are connected to the first protective shell 1 and the second protective shell 2 via a first spring 4. The elastic plates 6 are fixed to the inner wall of the protective covers 5. When the pellet is subjected to external forces such as collision or compression, the elastic plates 6 first contact the pellet and undergo elastic deformation, absorbing part of the impact force. Subsequently, the protective covers 5 move backward under the action of the first spring 4, further dispersing and buffering the impact force. This multi-layer buffering mechanism effectively reduces the direct impact of shock on the pellets, preventing them from breaking or pulverizing, thus significantly improving their compressive strength. The contact block 8 of the second protective shell 2 is aligned with the sliding hole 7 of the first protective shell 1 and inserted into the sliding hole 7, initially aligning the first and second protective shells 1 and 2. When the contact block 8 contacts the insertion rod 10, the insertion rod 10 moves upward. When the contact block 8 moves to the leftmost position, the insertion rod 10 disengages from the contact block 8 and resets under the action of the second spring 13, thus limiting the contact block 8. When the pellets need to be removed, the insertion rod 10 is pulled by external force, causing it to disengage from the left side of the contact block 8, releasing the lock. The first and second protective shells 1 and 2 can then be quickly separated, exposing the internal pellets for easy removal.

[0024] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
