Reciprocating type section mill smoke dust collecting device

Abstract

The invention discloses a reciprocating type section mill smoke and dust collecting device which comprises a dust suction hood and a dust suction pipe, the dust suction hood is formed by hinging two hood bodies, each hood body comprises an outer hood and an inner hood, the outer hood is connected with the periphery of the inner hood, a cavity is formed between the outer hood and the inner hood, dust suction holes are evenly formed in the inner hood, and the dust suction pipe is arranged in the cavity. The interior of the inner cover is divided into a plurality of dust suction chambers through a plurality of partition plates, the lower end of the dust suction pipe is connected with a uniform distribution pipe, the uniform distribution pipe is connected with pull pipes with the number corresponding to that of the dust suction chambers, the upper end of the outer cover is provided with an air outlet hole, the air outlet hole is connected with an arc-shaped suction pipe in sliding connection with the pull pipes, and each dust suction chamber corresponds to a suction pipe. And the side wall of the pull pipe is provided with an insertion plate for adjusting the air volume. The size of the opening of the dust hood can be adjusted according to requirements, generated water vapor and dust can be comprehensively absorbed, and the dust collection effect and efficiency of the dust hood are improved.

Description

technical field [0001] The invention relates to the technical field of steel dust removal, in particular to a fume and dust collecting device for a reciprocating section steel rolling mill. Background technique [0002] In the H-beam production process, a large amount of water vapor is generated during the rolling of the red-hot billet, the iron oxide powder falls off, and the cooling water vapor occurs. Although part of the iron oxide dust is taken away by the high-pressure water, there is still a large amount of ultra-fine iron oxide dust. The water vapor diffuses upward to form yellow-white steam pollutants, the main components are Fe2O3, FeO, water vapor, etc., which escape in the workshop. These large amounts of steam containing ultra-fine iron oxide dust not only seriously pollute the working environment in the workshop, It affects the health of workers. At the same time, it also causes a wide range of dust pollution and water vapor corrosion for some electrical compon...

Problems solved by technology

[0002] In the production process of H-shaped steel, a large amount of water vapor is generated during red-hot billet rolling, iron oxide powder falls off, and the water vapor is cooled. Although part of the iron oxide dust is taken away by high-pressure water, there is still a large amount of ultra-fine iron oxide dust with it. Water vapor diffuses upwards to form yellow-white steam pollutants, the main components of which are Fe2O3, FeO, water vapor, etc., which escape in the workshop building. These large amounts of steam containing ultra-fine iron oxide dust not only seriously pollute the working environment in the workshop, It affects the health of workers, and at the same time, it also causes large-scale dust pollution and water vapor corrosion to some production equipment in the workshop, such as transformers, sensors, high-precision hydraulic valve groups and other electrical components.

[0003] At present, the water mist dedusting equipment invested in the medium-sized line roughing mill in the section steel plant adopts a fixed-size structure. When processing section steel of different sizes, some section steel is relatively wide and some section steel is relatively narrow. In order to meet the maximum size section steel, the dust collection cover The design size is large, the cost investment is high, and the air volume is wasted when processing relatively narrow steel sections. The current dust collection device is only a simple cover body, and the dust collection effect is not good, and it is easy to cause water vapor and dust to overflow.
