Description

Technical Field

[0001] This utility model relates to the field of sintering loosening technology, and in particular to a sintering loosening device. Background Technology

[0002] Sinter production is the first and primary process in blast furnace smelting. Sintering is the process of mixing various iron-containing materials with a certain amount of flux and fuel in a certain proportion, wetting and mixing the mixture, distributing it evenly on the sintering machine, and then sintering it from top to bottom by ignition and ventilation.

[0003] With the development of larger sintering machines, the material layer thickness is becoming increasingly thicker. In the process of sinter production, in order to ensure the output and quality of sinter, the sintering machine must have good air permeability. Therefore, after the mixture enters the sintering machine, a loosener is generally installed under the round roller distributor to loosen the material and improve the air permeability of the material layer.

[0004] Traditional material releasers are generally made of solid round steel and are installed in two staggered rows on a support. They are prone to deformation or material sticking during use, which can cause material shortages or grooves during the material distribution process and lead to production accidents. Therefore, there is an urgent need to explore a material releaser that is not easily deformed or sticky. Utility Model Content

[0005] The purpose of this invention is to provide a material loosener for sintering, which solves the problems of easy deformation and material sticking in existing sintering material looseners.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] This utility model provides a sintering material loosening device, comprising:

[0008] Feeder support;

[0009] Loosening rods, wherein several loosening rods are located on the loosening device support; the cross-sectional shape of the loosening rods is rhomboid;

[0010] A positioning element is provided on the loosener bracket to detachably and fix the loosening bar to the loosener bracket.

[0011] Furthermore, the loosening rods are spaced apart on the loosening device support along the extending direction of the loosening device support.

[0012] Furthermore, the loosening device support includes a base plate and a loosening rod sleeve fixedly connected to the base plate. The base plate is used to provide overall support, and the loosening rod sleeve is for the loosening rod to be inserted.

[0013] Furthermore, the inner contour of the loosening bar sleeve is adapted to the outer contour of the loosening bar.

[0014] Furthermore, the transverse and longitudinal spacing of any two adjacent loosening bars is the same.

[0015] Furthermore, the acute angle of the rhomboid cross-section of the loosening bar is 30°~45°.

[0016] Furthermore, the positioning element is a positioning bolt or a positioning buckle.

[0017] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0018] This utility model discloses a sintering material loosener, which improves the original solid round steel loosening bar into a loosening bar with a rhomboid cross-section and angular edges, thus avoiding material sticking to the bar, stabilizing the material distribution in the sintering machine, and improving the air permeability of the material layer.

[0019] Furthermore, the loosening bar is made of stainless steel, and the moment of inertia (bending stiffness) of the rhomboid cross-section is usually larger than that of a circle of the same cross-sectional area, which fully utilizes the characteristic of not being easily deformed, and the overall loosening device is not easily deformed.

[0026] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0027] In this embodiment of the invention, a sintering material loosener is provided, such as... Figures 1 to 3 As shown, it includes a material releaser bracket 1, a material release bar 2, and a positioning component 3.

[0028] Specifically, several loosening rods 2 are arranged on the loosening device support 1 along its extension direction. Adjacent loosening rods 2 are spaced apart, meaning they are spaced out on the loosening device support 1. In this embodiment, the lateral or longitudinal spacing between adjacent loosening rods 2 is the same. This regular arrangement ensures that the sintered material can be uniformly loosened, and the specific spacing can be selectively adjusted. Furthermore, the loosening rods 2 in this embodiment are made of stainless steel, which has strong resistance to deformation.

[0029] In this embodiment, the loosening device bracket 1 includes a base plate 101 and a loosening rod sleeve 102 fixedly connected to the base plate 101. The base plate 101 is used to provide support for the overall frame, and the loosening rod sleeve 102 is used for inserting the loosening rod 2.

[0030] In order to ensure that the loosening rod 2 is stably inserted into the loosening rod sleeve 2, in this embodiment, the inner contour of the loosening rod sleeve 102 is set to match the outer contour of the loosening rod 2, thereby preventing the loosening rod 2 from moving or displacing inside the loosening rod sleeve 102.

[0031] In this embodiment, to prevent the sintering material from sticking to the material and to prevent deformation, the cross-sectional shape of the loose material rod 2 is set to rhombus. The angular structure of the rhombus cross-section can more effectively break the "arch bridge effect" of the sintering material accumulation, forming more irregular pores, enhancing the uniformity of airflow distribution, reducing bed resistance, and thus improving the permeability during the sintering process. In contrast, the circular cross-section in the prior art, due to its smooth surface, causes less disturbance to the material, and its effect on improving permeability is relatively weak.

[0032] Furthermore, the acute angle design of the rhomboid edges generates stronger shearing force during operation, more thoroughly breaking up clumps of material. In this embodiment, the acute angle of the rhomboid cross-section of the loosening bar 2 is 30°~45°.

[0033] The rhomboid structure can also create dynamic material flow at the edge of the equipment, reducing the problem of material retention at the edge caused by traditional round cross-section loose bars, and improving the overall sintering uniformity.

[0034] Regarding resistance to deformation, the moment of inertia (bending stiffness) of a rhombus cross-section is generally larger than that of a circle with the same cross-sectional area; furthermore, the edges of a rhombus disperse stress in multiple directions under load, preventing stress concentration. Combined with the stainless steel material of the loose bar 2, this ensures that it remains undeformed.

[0035] In this embodiment, a positioning element 3 is provided on the loosening device bracket 1 to detachably and securely connect the loosening bar 2 and the loosening device bracket 1. In this embodiment, the positioning element 3 can be a positioning bolt or a positioning clip, achieving a stable connection while also considering ease of installation and maintainability. Alternatively, the two can be directly welded together, but this method is not detachable, and the weld joint needs to be cut when maintaining or replacing the loosening bar 2. Another option is to machine an external thread onto the outer surface of the loosening bar 2 and an internal thread onto the inner wall of the loosening bar sleeve 102 on the loosening device bracket 1, achieving a fixed connection through the engagement of the external and internal threads.

[0036] In summary, the sintering material loosener disclosed in this utility model, through its rhomboid cross-section design, high rigidity structure, and integrated assembly, achieves multiple advantages such as improved air permeability, reduced material sticking, enhanced deformation resistance, optimized material loosening, and convenient maintenance. It is suitable for various sintering processes, can significantly improve production efficiency and equipment lifespan, and has high industrial application value.

Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be used to limit the protection scope of this utility model.
