Roller scrapper

Abstract

The invention provides a roller scrapper which comprises an abrasion-resistant plate structure. The abrasion-resistant plate structure is mainly formed by splicing three abrasion-resistant plates distributed end to end sequentially. By adoption of the abrasion-resistant plate structure, longitudinal gaps are eliminated, gap slag inclusion and deformation are avoided, and the strength of the abrasion-resistant plate structure is enhanced. The roller scrapper further comprises a current monitoring device. The current monitoring device comprises a current transformer, an intelligent protector module and an operating console which are electrically connected. The current transformer is connected into a roller scraper operating loop in series. The current transformer can sense a current value in the roller scrapper operating loop and transmits the current value to the intelligent protector module. The intelligent protector module compares the received current value with a current alarm value, the current monitoring device enables the roller scrapper operating loop to be disconnected when the received current value exceeds the current alarm value, and the roller scrapper stops in time; and faults can be eliminated conveniently in time, the fault treatment time is shortened, and the fault treatment cost is reduced.

Description

technical field [0001] The invention relates to a slag processing equipment, in particular to a drum scraper machine. Background technique [0002] At present, the converter slag and electric furnace slag produced in the steelmaking process are all processed by the drum slag treatment equipment, and the operation of the drum equipment is directly related to the rhythm of steelmaking production. The drum scraper is one of the components of the drum discharge device. The drum discharge device is composed of an upper chain conveyor and a lower roller scraper. The upper chain conveyor is mainly responsible for transporting the steel slag after being processed by the drum body, and the lower roller scraper is mainly responsible for transporting the steel slag overflowed from the upper chain conveyor. Steel slag leaking from the gap. The existing roller scraper machine is not perfect in design, and there are many problems in the production and operation process. [0003] The sc...

AI Technical Summary

Problems solved by technology

The wear plate structure is composed of multiple longitudinal wear plates and multiple horizontal wear plates. When multiple vertical wear plates and multiple horizontal wear plates are spliced, it is inevitable that the wear plate structure will have multiple Gap and multiple longitudinal gaps, that is, multiple horizontal wear-resistant plates and vertical wear-resistant plates are laid on the bottom plate, and there is a certain gap between the wear-resistant plates and the wear-resistant plates. The steel slag is partially in contact with the bottom plate, causing corrosion to the bottom plate; in order not to affect the production, the inspection personnel replace the broken and degummed wear-resistant plate with an iron plate of the same size, but after a period of use, the gap between the iron plate is prone to occurrence Deformation, so that the scraper is blocked in the process of scraping steel slag, and in severe cases, the chain of the scraper conveyor will be broken

The failure rate of the roller scraper conveyor is relatively high, and the repair time after the failure is long, which seriously affects the operation efficiency of the roller

According to statistics, during the repair process of the roller scraper machine after a failure, the roller equipment needs to be stopped for two days, and more than 30 man-hours of manual maintenance are required.

This not only increases the repair time and repair cost of the scraper conveyor, but also reduces the operating efficiency of the roller equipment and the slag treatment rate, which seriously restricts the slag treatment rhythm of the roller

[0004] In addition, when the roller scraper is subjected to greater resistance, it will cause the whole to be pulled over, or the chain will be broken, resulting in a large degree of damage to the roller scraper.

When the roller scraper breaks down, the existing power transmission method cannot stop its operation immediately in a sudden state, causing the whole roller scraper to be pulled over or the chain to be broken

However, a set of transmission chain costs 43,000 yuan, and it takes about 7 days to overhaul and replace it once, which further increases the cost and time-consuming of overhaul
