Description

The Mei Liu transportation system of conveyer load distribution detection and energy-saving control method thereof
Technical field
The present invention relates to the Mei Liu transportation system technical field of conveyer load distribution detection, particularly to The Mei Liu transportation system of a kind of conveyer load distribution detection and energy-saving control method thereof.
Background technology
Rubber conveyer is high due to its conevying efficiency, is the capital equipment of underground coal mine coal stream transport.Mesh The front transportation system of mine coal stream mostly uses extensive production model, and load matched rate is low, equipment idle running Rate is high, overall efficiency is low.Owing to the coal of coal stream transport has great lack of uniformity, therefore adhesive tape is defeated Sending machine mating electrical type selecting bigger than actually required capacity, actual moving process is medium-term and long-term is in low load Lotus runs, and efficiency is low.Ribbon conveyer, when transportation system designs, is usually and considers by maximum coal amount , and the Type Selection Principle of reductor and motor to be grade lean on very much not by little, so ribbon conveyer is joined The driving motor put generally individually has 20%~45% surplus capacity, adds that ribbon conveyer is often in gently Carry, no-load running state, cause motor often in less than 50% inefficient duty.Band Formula conveyer, in running, is high-speed cruising under zero load, underloading, heavy condition, and unloaded With during underloading, the equipment such as motor, reductor, cylinder, carrying roller, adhesive tape are created unnecessary mill Damage and power consumption, shorten the service life of equipment.Traditional single strips of adhesive tape conveyer Energy Saving Control Method one is to run power according to conveyer to reduce the conveyer speed of service, reaches energy-saving effect.Due to Conveyer transportation range is long, and conveyer runs changed power and seriously lags behind fortune coal amount change, if come Coal amount becomes suddenly big, and it is little to run changed power, and sealing-tape machine improves running speed the most in time, easily In transfer point generation coal piling accident.Another one tradition energy-saving control method is detection tail real-time coal stream Size controls sealing-tape machine running speed, if be detected that coal amount diminishes in real time, then reduces conveyer fortune Rotary speed reaches energy-saving effect.Due to the lack of uniformity of coal production, carrying out coal amount may frequently change, If frequently adjusting the conveyer speed of service, it is unfavorable for conveyer reliability service, if detection is not simultaneously Accurately it is easily caused coal piling fault.Thus while at present the configured frequency converter of ribbon conveyer etc. are energy-conservation Equipment, but energy-saving effect need to improve.
Summary of the invention
It is an object of the invention to the defect overcoming prior art to exist, it is provided that one can effectively solve existing The conveyer load of You Meiliu transportation system energy-saving effect difference and the problem that is easily generated coal piling fault is divided The Mei Liu transportation system of cloth detection and energy-saving control method thereof.

Analyzing and processing in step C described in technique scheme particularly as follows:
If automatically controlled host supervision carries to this conveyer load more than 1/2 specified coal amount or upstream Machine head section coal stream is more than 1/2 specified coal amount, controls frequency converter output frequency and power, makes conveyer It is in normal speed to run;
If automatically controlled host supervision carries to this conveyer load less than 1/2 specified coal amount and upstream Machine head section coal stream is less than 1/2 specified coal amount, controls frequency converter output frequency and power, makes conveyer It is in the 1/2 specified speed of service to run, reaches energy-saving effect;
If automatically controlled host supervision is to this conveyer no-load running, and upstream conveyor is the most unloaded The Duan Yunhang time requires interval time more than motor thermal starting, and rubber conveyer stops;
If conveyer is in low speed energy-saving run state, automatically controlled host supervision is to upstream conveyor machine Head section coal stream is more than 1/2 specified coal amount, controls frequency converter output frequency and power the most in time, improves defeated Send machine running speed, prevent coal from transporting the most in time and cause coal piling accident.
Power converter output described in technique scheme is equal to the power P driving motorM, it calculates public affairs Formula is PM=PA/η;Wherein, PABeing the shaft power of conveyer driving cylinder needs, η is that motor shaft is to driving Power transfer efficiency between dynamic rolling.
Conveyer described in technique scheme drives shaft power P of cylinderA=Fu·v/1000;Wherein, Fu For circumference driving force, FuOvercoming various resistance sum equal to conveyer needed for when running well, v is defeated Send machine running speed, in the case of conveyer parameter is fixing, circumference driving force FuPrimarily as every meter Weight of material q on conveyer belt increases and increases.
Using after technique scheme, the present invention has a following positive effect:
(1) present invention is suitable for current national and is implementing energy-saving and emission-reduction industrial policy, to relevant field, The energy-saving and emission-reduction of industry propose clear and definite task and requirement, lay particular emphasis on key industry and major fields joint The refinement of energy Mitigation options and the quantization of target.
