Steelmaking slag conveying production line and control system thereof

Abstract

The invention discloses a steelmaking slag conveying production line, and relates to the technical field of conveying devices. The production line comprises a plurality of raw material main conveying devices which are arranged side by side, each raw material main conveying device is provided with a dust conveying device, the multiple dust conveying devices are jointly connected to an air draft conveying pipeline, an outlet of each main raw material conveying device is connected with a quantitative material conveying device, outlets of the quantitative material conveying devices are jointly connected with a collecting conveying device, a discharging end of the collecting conveying device is connected with an auxiliary raw material conveying device, and a discharging end of the auxiliary raw material conveying device is connected with a steel smelting furnace. According to the production line and the control system, the problems that in the prior art, a device cannot meet the requirement for material conveying in the steelmaking process of a steelmaking plant, functions are few, and manual auxiliary conveying is needed are solved.

Description

Technical field[0001]The present invention relates to the technical field of delivery devices, and more particularly to a steelmaking slag delivery production line and a control system thereof.Background technique[0002]Blast furnace steelmaking needs to transfer all kinds of slag, therefore requested a one-integrated delivery device for conveying operation of the slag of the particulate structure, and utilizing the delivery device can effectively improve the conveying efficiency of the slag, make it transport operation More convenient, after mixing all kinds of slag, it is tied to the blast furnace along the production line.[0003]A patent of CN211894892U is disclosed in the prior art, which includes a conveying frame and a fixed bottom plate, and the conveying frame is fixedly mounted on the upper portion of the fixed bottom plate, and the upper outer surface of the fixed bottom plate is fixedly mounted with a pressure pump, and the upper end of the fixed bottom plate is close to th...

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
