Description

A kind of ball adding controller of coal pulverizer energy-saving control system

Technical field

Coal pulverizer energy saver field is the utility model is related to, more particularly to a kind of ball adding of coal pulverizer energy-saving control system Controller.

Background technology

Coal pulverizer belongs in pulverized coal preparation system, most important subsidiary engine.During coal-grinding, steel ball is constantly ground coal pulverizer Damage, steel ball amount is constantly reduced, and small ball is on the increase in cylinder, reduces pulverizer capacity.So it must determine in operation Phase adds steel ball.In day-to-day operation, should supplement daily a number of Φ 50mm or Φ 60mm or Φ 40mm and other not Isodiametric steel ball, to ensure electric current during the optimal steel ball coefficient of fullness of ball mill.According to the rules, ball mill operation it is every 6~ After the cycle of 12 months or 3500~7500h, steel ball should be screened once, diameter is less than 15~20mm small ball and gold Category waste cleans out.To ensure the effect of abrasion, and ensure the output of grinding machine.

The method of traditional addition steel ball, such as Liaoning JZ power plant, it is by artificial, from the upper of the coal handling system of coal breakage Window, method manually need the quantity added according to estimation, are manually looked into several additions on a daily or weekly basis.

So existing problems and disadvantages are：Because coal pulverizer running environment noise is big, at the same run and live distance than Farther out, it is necessary to carry out physics carrying from stock ground, it is necessary to expend the manpower compared；Because addition steel ball is applied more than 0 meter Work, belong to work high above the ground, there is bigger danger；Added simultaneously in window, there can be certain pollution to environment；And grinding machine During thing is run, inside belongs to the operation of malleation or negative pressure, open addition window can to air quantity, blast, temperature, etc. refer to Mark has the influence of variable, to the judgement of the effect of output after determination addition that can not be promptly and accurately, has pole to the effect of addition Big uncertainty.

The method of traditional addition steel ball, typically feeder add, exactly put, be added to from the raw material cabin storage space of material Belt conveyor, according to the display of weighing of Gravimetric Coal Feeders, judge the size of steel ball addition is either how many, it is so existing to ask Topic is, because the humidity of coal and impurity are unstable, the proportion of steel ball and the proportion error of coal are very big, at the same be again Weighed in motion conveying, there is very big inaccuracy.
