Embodiment Construction

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0025] see Figure 1-6 , the present invention provides a technical solution: an oxygen lance dust cover, including a protective mechanism 1, a power mechanism 2 and a bottom mechanism 3, the protective mechanism 1 is set on the power mechanism 2, and the bottom end of the power mechanism 2 is slid and inserted In the bottom mechanism 3, the two ends of the protection mechanism 1 are respectively fixedly connected with the power mechanism 2 and the bottom mech...

Abstract

The invention belongs to the technical field of metallurgical industry accessories, and particularly relates to a dust cover for an oxygen lance. The dust cover comprises a protection mechanism, a power mechanism and a bottom mechanism, the protection mechanism sleeves the power mechanism, the bottom end of the power mechanism is slidably inserted into the bottom mechanism, and the two ends of the protection mechanism are fixedly connected with the power mechanism and the bottom mechanism respectively. After the protection mechanism is installed on the oxygen lance, the protection mechanism comprises a gooseneck type dustproof pipe, a positioning chain and a top moving disc, when a sliding rod body and a top sliding rod move upwards, the top moving disc drives the gooseneck type dustproof pipe to be unfolded, when the gooseneck type dustproof pipe is unfolded, the chain is unfolded along with the gooseneck type dustproof pipe, and therefore the situation that the gooseneck type dustproof pipe is unfolded unevenly is avoided, and the opening of the gooseneck type dustproof pipe is ensured, and in the working process of the oxygen lance, the gooseneck type dustproof pipe can filter 95% of waste gas, the waste gas is prevented from being directly discharged into air in the using process of the oxygen lance, and safety accidents caused by the fact that steel slag is splashed out of a furnace in the working process of the oxygen lance can be avoided.

Description

technical field [0001] The invention relates to the technical field of metallurgical industry accessories, in particular to an oxygen lance dust cover. Background technique [0002] In the prior art, the furnace opening is not tightly sealed during oxygen blowing in the converter operation, and harmful gases and steel slag will overflow out of the furnace, causing great pollution to the environment of the working area and bringing safety hazards to the staff. [0003] Therefore, it is necessary to add protective equipment on the oxygen lance, and the traditional protective equipment is not flexible and convenient to use, so the present invention proposes an oxygen lance dust cover. Contents of the invention [0004] The object of the present invention is to provide an oxygen lance dust cover to solve the problem in the background art that the exhaust gas cannot be filtered and the steel slag splashes everywhere during the use of the existing oxygen lance. [0005] In orde...
