Electric drive type sealing device of blast furnace skip car

Abstract

The invention relates to an electric drive type sealing device for a blast furnace skip car and belongs to the technical field of environmental protection of blast furnace skip cars in the metallurgical industry. According to the technical scheme, a sealing shed cover is arranged at a loading and unloading port of a blast furnace skip car (1), the sealing shed cover comprises skip car sealing shedcloth (2) and a shed cover keel (10), the two ends of the shed cover keel (10) are installed on two shed cover rotating shafts (3) respectively, and the two shed cover rotating shafts (3) are rotationally connected to the side walls of the two sides of the blast furnace skip car (1) respectively; the shed cover keel (10) is composed of multiple layers of keels, the keel on the outermost side is in key connection with the shed cover rotating shafts (3), the keel on the innermost side is fixed to the upper edge of the blast furnace skip car (1), and the keel in the middle is in sliding connection with the shed cover rotating shafts (3); and the skip car sealing shed cloth (2) is fixed on the shed cover keel (10). The electric drive type sealing device has the beneficial effects that forwardand reverse rotation driving of the servo motor is adopted, so that the blast furnace skip car completes sealing and opening actions of the loading and unloading groove in the advancing process, anddust is prevented from overflowing in the conveying process of raw materials.

Description

technical field [0001] The invention relates to an electric-driven airtight device for a blast furnace charging car, which belongs to the technical field of environmental protection for charging a blast furnace inclined bridge charging car in the metallurgical industry. Background technique [0002] The blast furnace feeding device of long-process iron and steel enterprises transports raw materials such as coke, sintering ore, pellets, lump ore, and limestone to the blast furnace through feeder trucks or belt conveyors. In the process of raw material transportation, the dust pollution during material receiving and unloading is relatively large, and the dust pollution during transportation is relatively small. Dust removal devices can be added to the receiving and unloading points to solve the problem of dust pollution. The dust pollution generated by the belt during the conveying process can be added to the belt corridor. However, the feed trucks of the blast furnace feedin...

Problems solved by technology

However, the feed trucks of the blast furnace feeding device run on the open inclined bridge, causing dust pollution in the process of conveying raw materials to the blast furnace, which has become a technical problem that must be solved in "winning the blue sky defense battle".

[0003] At present, there is no mature technology for dust pollution in the operation of blast furnace skips at home and abroad. Among them, the patented technology of "blast furnace skips with self-moving covers" requires major changes to the belts and bins of the feeding device, and the sealing cover The material receiving port on the top is not completely closed, and it cannot completely prevent dust from overflowing during operation.

In addition, in order to control the dust generated during the feeding operation of the feeding trucks, some iron and steel enterprises seal the inclined bridges of the feeding trucks with color steel or other light materials. extra load
