Abstract
The invention relates to an automatic proportioning, loading and unloading control system of a ferroalloy submerged-arc furnace. A proportioning method of the control system is batch proportioning and the control system mainly comprises upper-level feeding control equipment, lower-level feeding control equipment, a metering hopper, an AVT/PT weighing control instrument, a PLC (Programmable Logic Controller), an industrial control computer and electrical control equipment; and according to the control system, the weighing control instrument is controlled through the PLC, so as to reach the aim of controlling ingredient proportioning. By adopting the control system provided by the invention, the whole system adopts a collected-distributed structure, so that the circumstance that the proportioning cannot be carried out when single equipment is damaged can be avoided; and various equipment of the control system can be monitored at any time, so that reliable guarantee is provided for production.
Description
Technical field
The invention belongs to smelting industry, particularly a kind of In The Sub-mergedfurnace of The Ferroalloys automatic blending, loading and unloading control system.
Background technology
Existing In The Sub-mergedfurnace of The Ferroalloys feeding, discharge system can realize the control of raw material cabin automatic charging, and this system mainly adopts high inclination-angle corrugated sidewall belt conveyer, and it is a kind of continuous conveying equipment.It is large that it has conveying capacity: compare with other conveyers, conveying capacity improves 1.5～2 times; Highly versatile: bare bones is identical with universal ribbon conveyer); Applied widely: as to be applicable to carry the materials such as rubble, lime stone, coal, sand, clay, sand burning powder, wood chip, grain; Being applicable to unit mass is 500～2500kg/m3, and maximum lumpiness is about the material of 100～250mm; Simple in structure, easy to maintenance, take up room little and reduce investment outlay, be convenient to the characteristics such as layout, thereby in industries such as coal, electric power, metallurgy, chemical industry, grains, extensively promoted the use of.But this system has can not automatic blending and the shortcoming such as complex operation.
Summary of the invention
For overcoming above-mentioned defect, the technical problem to be solved in the present invention is to provide a kind of easy to operate and novel In The Sub-mergedfurnace of The Ferroalloys automatic blending, loading and unloading control system that can automatic blending.
A kind of In The Sub-mergedfurnace of The Ferroalloys automatic blending, loading and unloading control system, the distribution of this control system is a batch batching, mainly upper and lower level feed control appliance, weigh-hatching plant, AVT/PT weighing controller, PLG, industrial control computer, electrical control equipment, consists of; The concrete steps of this control system are:
(1) sent to the deposit feed bin by feeding car when raw material after, then by the deposit feed bin, arrive oscillating feeder;
(2) oscillating feeder is transported to raw material the hopper of weighing;
(3) hopper of weighing is delivered to the AVT/PT weighing controller by weighing-up wave, and the dosage that the AVT/PT weighing controller is set according to industrial control computer, control by PID intelligent regulator and PLC program;
(4) reach predetermined value when proportion scale, PLC sends instruction to be stopped feed and prints the batching value, opens simultaneously subordinate's feeding device, thereby reaches the purpose of accurate proportioning;
The raw material that (5) will prepare is finally sent into mineral hot furnace by feed belt.
Adopt control system of the present invention, whole system adopts the collective and distributive type structure, can avoid single equipment to damage the situation that batching can't be carried out, and various device of the present invention can monitor at any time, for production provides reliable assurance.
Description of drawings
Fig. 1 is the structured flowchart of automatic blending of the present invention, loading and unloading control system.
The specific embodiment
In The Sub-mergedfurnace of The Ferroalloys automatic blending of the present invention, loading and unloading system, be different from general metallurgy proportioning and chemical industry batching, its distribution is a batch batching, mainly by upper (under) level feed control appliance, weigh-hatching plant, AVT/PT weighing controller, PLG, industrial control computer, electrical control cabinet and relevant auxiliary equipment form.
Batching is the prerequisite of blast furnace high-quality, high yield, low consumption, in time, batching, material loading are the prerequisites that guarantees furnace processor and product quality accurately.So-called batching be exactly according to blast furnace to the product quality requirement of crude fuel and the chemical property of raw material, with various raw materials, solvent, fuel, substitute in time return mine etc. carry out by a certain percentage with addition of operation.The purpose of batching is the requirement according to ironmaking processes, and various iron-bearing material, solvent and fuel are prepared burden accurately,, to obtain higher productivity ratio and the high-quality molten iron of stable performance, meets the requirement that blast furnace process is produced.Control system of the present invention need to realize the report printing of automatic charging and material loading data, embodies the stability of a system, advance and economic and practical.
As shown in Figure 1, manufacturing enterprise will according to the actual production place select suitable being installed into (under) grade feeding device and weigh-hatching plant, with conveying and the gage work of completing material.
The concrete steps of automatic blending of the present invention, loading and unloading control system:
(1) sent to the deposit feed bin by feeding car when raw material after, then by the deposit feed bin, arrive oscillating feeder;
(2) oscillating feeder is transported to raw material the hopper of weighing;
(3) hopper of weighing is delivered to the AVT/PT weighing controller by weighing-up wave, and the dosage that the AVT/PT weighing controller is set according to industrial control computer, control by PID intelligent regulator and PLC program;
(4) reach predetermined value when proportion scale, PLC sends instruction to be stopped feed and prints the batching value, opens simultaneously subordinate's feeding device, thereby reaches the purpose of accurate proportioning;
The raw material that (5) will prepare is finally sent into mineral hot furnace by feed belt.
The advantage of automatic blending of the present invention, loading and unloading control system:
1. whole system adopts the collective and distributive type structure, can avoid single equipment to damage the situation that batching can't be carried out; Tactic pattern: " static weighing system+computer control+PLC control system ", open good, be easy to expansion;
2. the RS485 fieldbus is adopted in the connection of each several part equipment, and is simple in structure, reliable; Computer real-time acquisition, demonstration in real time, real-time controlling run operating mode and relevant data, stable performance;
3. data storing and analytic function, can record and read truck train number and operational circumstances, failure response accurately and timely, can automatically show or print fault time, place and character, and carry out sound and light alarm; Can be long-range/local automatically, manually local/instrument control operation, can't carry out thereby avoid single equipment to damage batching;
4. control system has the interlock protection function, and equipment under test is arranged various detections and defencive function.
