Description

Technical Field

[0002] Sintering is a process in which fine-grained ore, coal powder, and other additives are mixed and then partially melted and reconsolidated into a bulk product through ignition and ventilation at high temperatures. This process is widely used in steel production to convert iron-containing raw materials into sintered ore suitable for blast furnace smelting. The loosening device plays a crucial role in the sintering process, improving the permeability of the sintering bed and ensuring uniform air distribution, thereby enhancing sintering efficiency and product quality.

[0003] Limitations of traditional feeders

[0004] Most of the sintering machine looseners currently used have the following problems:

[0005] Complex structure: The traditional loosening device has a complex structure, is inconvenient to install and maintain, and is prone to failure.

[0006] Inconvenient maintenance: The loosening blade is easy to wear after long-term use, but the traditional loosening device design makes it difficult to replace the blade, increasing maintenance costs and downtime.

[0007] Poor loosening effect: Due to design limitations, the traditional loosening device has an unsatisfactory loosening effect on the sintering material layer and cannot effectively improve the air permeability, thus affecting the sintering efficiency.

[0008] Low degree of automation: Many traditional loosening machines still require manual operation, and the degree of automation is not high, which affects production efficiency. Utility Model Content

[0033] This new type of loosening device for sintering machine is mainly used to improve the permeability of the sintering material layer and increase the output and quality of sintered ore. Its working principle is as follows:

[0034] The loosening function of the loosening blade:

[0035] The loosening blade passes through the sintered material layer through its serrated or wavy blade body 15, breaking up the materials that are bonded together through cutting and dispersing effects, making the distribution more uniform, thereby improving the permeability of the material layer.

[0036] The L-shaped loosening blade comprises a handle and a blade body 15 , wherein the blade body 15 is an inclined structure. This design makes it easier for the blade to cut into the material, thereby improving the loosening efficiency.

[0037] Working principle of transmission mechanism:

[0038] A limit ring 4 is installed on the top of the base 1. A transmission port 6 is provided on the limit ring 4, and a transmission mechanism (such as the gear ring 3) is connected through the transmission port 6.

[0039] The side of the limiting ring 4 is provided with a mounting edge 5 , which is connected to the base 1 through bolts. The bolts are fixed to the base 1 through a threaded structure, thereby ensuring the stability of the limiting ring 4 .

[0040] A slide groove 9 is provided on the top of the base 1 and the bottom of the limiting ring 4. The annular rod 10 on the gear ring 3 is slidably connected to the slide groove 9, so that the gear ring 3 can move smoothly in the slide groove 9 to achieve precise transmission.

[0041] The gear ring 3 is connected to the output end of the driving motor 7 through a transmission gear. The driving motor 7 drives the gear ring 3 to rotate, thereby driving the loosening blade to move, thereby realizing the loosening function.

[0042] Control function of valve plate 12:

[0043] A valve plate 12 is provided at the bottom of the base 1 . Both ends of the valve plate 12 are rotatably mounted in the cavity of the base 1 via a rotating shaft, and the rotating shaft at one end of the valve plate 12 passes through the base 1 .

The valve plate 12 is rotated by the driving of the rotating motor 11 to control the opening and closing of the material loosener.

[0045] Design optimization of blade body 15:

[0046] The blade body 15 is a cross structure, and the sides of the blade body 15 are provided with serrations. This design can better cut and disperse the material and improve the loosening effect.

[0047] Working principles of each preferred technical solution

[0048] Installation of limit ring 4:

[0049] The limiting ring 4 is connected to the base 1 by bolts, and the bolts are fixed to the base 1 by a threaded structure, which ensures the stability of the limiting ring 4 and prevents it from loosening or shifting during operation.

[0050] The transmission opening 6 on the limiting ring 4 is used to connect the transmission mechanism to ensure the stability and reliability of the transmission.

[0051] Connection between the chute 9 and the annular rod 10:

[0052] Slide grooves 9 are provided on the top of the base 1 and the bottom of the limiting ring 4. The annular rod 10 on the gear ring 3 is slidably connected to the slide grooves 9, so that the gear ring 3 can move smoothly in the slide grooves 9 to achieve precise transmission.

[0053] The design of the slide groove 9 ensures the movement trajectory of the gear ring 3 and avoids transmission misalignment caused by vibration or impact.

[0054] Control of valve plate 12:

[0055] The valve plate 12 is installed in the cavity of the base 1 through a rotating shaft. The rotating shaft at one end passes through the base 1. The valve plate 12 is rotated by the driving of the rotating motor 11 to control the opening and closing of the material loosener.

[0056] The design of the valve plate 12 enables the loosener to control the inflow and outflow of materials as needed, thereby realizing automatic control.

[0057] Optimized design of loosening blade:

[0058] The loosening blade is of L-shaped structure, and the blade body 15 is of inclined structure. Such a design makes it easier for the blade to cut into the material, thereby improving the loosening efficiency.
