Embodiment Construction

[0021] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0022] It is worth noting that the orientation words such as "up" and "down" involved in this article are all determined relative to the perspective of the drawings, and are only for the convenience of description, and cannot be understood as limitations on the technical solution.

[0023] Such as figure 1 with figure 2 As shown, a method to solve the abnormal empty value of the material tank. First, the existing material feeding system includes a material receiving tank 1, a material feeding gate 2, a dust collector 4 and a weighing tank 5 connected sequentially from top to bottom. , There is also a soft connection 3 between the feeding gate 2 and the dust collector 4 to facilitate installation and disassembly, and the application of different sizes. The method includes the following steps: at the outer edge of the dust removal ring 6 in the dust ...

Abstract

The invention relates to a method and a device for solving the problem of abnormal empty value of materials in a charging bucket. The method comprise the following steps of intermittently blowing a dust removal loop by using compressed air in the charging bucket of a conventional blast furnace charging system, installing a connecting pipe to communicate the dust removal loop with a dust removal system, forming dust removal air in the connecting pipe by using an exhaust fan of the dust removal system, and collecting dust blown out of the dust removal loop. The device for solving the problem ofabnormal empty value of the materials in the charging bucket is easy to transform, the daily consumption of the compressed air is low, no dust is accumulated in the dust collection loop, hard contactcaused by blockage of the dust collection loop in a dust collector is eliminated, and the problem of abnormal empty value of the materials in the charging bucket is solved.

Description

technical field [0001] The invention relates to the technical field of metallurgical machinery, more specifically, it relates to a method and a device for solving the abnormal empty value of the charging tank of the blast furnace feeding system. Background technique [0002] The abnormal empty value of the material tank in the blast furnace feeding system directly affects the deviation between the actual charging weight of the blast furnace material tank and the weighed weight of the material tank. , leading to disordered gas flow in the blast furnace, which has a great impact on furnace conditions and fuel consumption. After a long period of time, it will directly lead to irregular furnace conditions. From the technical analysis of the blast furnace charging system equipment, the main reason for the abnormal empty value of the material tank is that the dust removal ring in the dust collector between the furnace top receiving tank and the weighing tank is blocked. Soft join...
