A steelmaking slag conveying production line and its control system

Abstract

A production line for conveying steelmaking slag, which relates to the technical field of conveying devices, including a plurality of main raw material conveying devices arranged side by side, each of which is provided with a dust conveying device, and several dust conveying devices are jointly connected to a draft conveying pipeline Above, the outlet of each raw material main conveying device is connected with a material quantitative conveying device, and the outlets of several material quantitative conveying devices are jointly connected with a converging conveying device, and the discharge end of the converging conveying device is connected with a raw material auxiliary conveying device, and the raw material auxiliary conveying device The discharge end is connected to the steelmaking furnace. The invention solves the problem that the device in the traditional technology cannot satisfy the material transportation during steelmaking in the steelmaking plant, has few functions, and needs manual auxiliary transportation.

Description

technical field [0001] The invention relates to the technical field of conveying devices, in particular to a steelmaking slag conveying production line and a control system thereof. Background technique [0002] Blast furnace steelmaking needs to transport all kinds of slag as ingredients, so it needs an integrated conveying equipment for conveying slag with granular structure. The conveying equipment can effectively improve the conveying efficiency of slag and make its conveying operation It is more convenient. After mixing various types of slag, it is fed into the blast furnace along the production line. [0003] A CN211894892U patent is disclosed in the prior art. The scheme includes a conveying frame and a fixed bottom plate. The conveying frame is fixedly installed on the upper part of the fixed bottom plate. A pressure pump is fixedly installed on the outer surface of the upper end of the fixed bottom plate. The two sides of the pressure pump are fixedly installed wit...

AI Technical Summary

Problems solved by technology

[0012] In view of the defects in the prior art, the present invention provides a steelmaking slag conveying production line to solve the problem that the device in the traditional technology cannot meet the particle size requirements of different steel materials and steelmaking slag; the slag is easy to jam on the crushing parts; Dust is easy to quickly block the filter parts in the dust filter device; when mixing materials, it is easy to lack the slag in a certain silo, and there is no guarantee of different slag batching ratios; when cleaning the mixing cylinder, it is necessary to stop the operation
