Waste gas suction and collection treatment device for steel casting workshop

Abstract

The invention belongs to the field of steel casting, and particularly relates to a waste gas suction and collection treatment device for a steel casting workshop, which comprises an alkali liquor box, the left end of the alkali liquor box is fixedly connected with an L-shaped pipe, the upper end of the L-shaped pipe is provided with a funnel, the lower end of the alkali liquor box is in threaded connection with a bottom cover, and a scraping rod is slidably connected in the alkali liquor box. A supporting rod is fixedly connected to the surface of the scraping rod, a shifting rod is fixedly connected to the lower end of the supporting rod, and a box cover is connected to the upper end of the alkali liquor box through threads; and the upper end of the box cover is fixedly connected with a connecting frame. A supporting piece is designed in a filter cartridge, a filter screen is designed at the lower end of the supporting piece for dust filtration treatment, a spring is mounted in the filter cartridge, the upper end of the spring is in contact with an upper cover, and the lower end of the spring is in contact with the supporting piece, so that when airflow passes through, the supporting piece and the filter screen vibrate under the action of the spring, and the filter screen is not prone to being blocked.

Description

technical field [0001] The invention relates to the technical field of iron and steel casting, in particular to a waste gas absorption and treatment device for an iron and steel foundry. Background technique [0002] Iron and steel casting is the foundation of industry. In the process of iron and steel casting, the raw materials are sintered and then melted in a blast furnace, then transferred to a secondary melting furnace for melting, and then the molten steel is drawn out for casting and other processes. [0003] During the steel casting process, some gases are produced in the steel furnace during smelting, mostly acid gases and some mineral dust, so the waste gas needs to be treated. Existing exhaust gas treatment devices often lack anti-blocking measures when filtering, and it is inconvenient to clean dust, and the exhaust gas has not been well utilized. Therefore, it is necessary to improve the prior art. Contents of the invention [0004] The purpose of the presen...
