Abstract
The invention relates to an automatic conveying device of a ball mill. A steel ball bin is designed to be composed of two parts including a ball storage tank and a ball collecting tank, and new steel balls are discharged into the ball storage tank and then roll into the ball collecting tank along an inclined way. When a material level detector detects that steel balls need to be added into a certain coal grinding mill, a control signal is sent by a PLC so as to control a corresponding lifting electromagnet to be electrified to absorb the steel balls; the lifting electromagnet stops after above a ball falling bucket of the certain coal grinding mill and then is powered off, the steel balls fall along a sliding way to run to an inlet of the ball mill at a slightly downward inclined angle, and a magnetic crane returns until the ball adding is finished.
Description
Technical field
The present invention relates to a kind of ball mill automatic conveying device.
Background technology
Ball mill pulverized system steel ball is that this not only consumes a large amount of labours by artificial feeding in course of conveying, and labour intensity is large, and disappear duration, affects exerting oneself of coal pulverizer, thus reduce pulverized coal preparation system efficiency, causes a large amount of economic losses.
The patent of current application has: Hou Yumin, utility model patent, the patent No.: CN201320665955.X; Cui Wanjun, patent of invention, the patent No.: CN201410002404.4.
A kind of ball mill automatic ball feeding machine, structure comprises electric block, steel ball grabbing device and chain-linked conveyer, and described electric block is provided with liftable chain hook; Described steel ball grabbing device comprises steel ball storehouse, liftable bag-breaking device, dials ball device and slideway, and described liftable bag-breaking device is positioned at steel ball storehouse and is connected with spiral lift, and bottom, described steel ball storehouse is provided with shaking device; Described group of ball device comprises to be dialled ball cylinder and dials ball pawl, and described slideway is positioned at dials ball device side, and described slideway is incline structure and was provided with ball quantity detection means in exit.
The control of steel ball loading capacity is the essential part of ball mill Optimization Work, and the shortcoming of prior art is: do not carry out intelligence for level of material for ball mill situation and add ball, operational efficiency is low, and cost is high.
Summary of the invention
For solving the problem, devise a kind of automatic conveying device of steel ball.Adopt pressure sensor to detect level of material for ball mill, and then control lifting electromagnet by PLC and from steel ball storehouse, capture steel ball transmit.
The present invention relates to a kind of ball mill automatic conveying device, described device comprises following structure:
Steel ball storehouse is designed to store ball pond and collection ball pond two parts formation, and new steel ball is discharged into and stores in ball pond, and steel ball rolls into Ji Qiuchi along inclination road; When Charge level measurer detects that certain coal pulverizer needs to add steel ball, send control signal by PLC, control the energising of corresponding lifting electromagnet and hold steel ball; Stop above the falling sphere bucket that lifting electromagnet arrives certain coal pulverizer, lifting electromagnet power-off, steel ball drop drives to ball mill porch along slideway with micro-tilt angled down, and magnetic hangs and returns, until this adds chou bundle.
Accompanying drawing explanation
Describe exemplary embodiment of the present invention in more detail by referring to accompanying drawing, above and other aspect of the present invention and advantage will become clearly, in the accompanying drawings:
Fig. 1 is ball mill steel ball automatic conveying device block diagram;
Fig. 2 is ball mill steel ball automatic grabbing device figure.
Detailed description of the invention
Hereinafter, more fully the present invention is described now with reference to accompanying drawing, various embodiment shown in the drawings.But the present invention can implement in many different forms, and should not be interpreted as being confined to embodiment set forth herein.On the contrary, provide these embodiments to make the disclosure will be thoroughly with completely, and scope of the present invention is conveyed to those skilled in the art fully.
Hereinafter, with reference to the accompanying drawings exemplary embodiment of the present invention is described in more detail.
With reference in accompanying drawing 1, Fig. 2, steel ball storehouse is designed to store ball pond 1 and collection ball pond 2 two parts formation, and new steel ball is discharged into and stores in ball pond, and steel ball rolls into Ji Qiuchi along inclination road.When Charge level measurer detects that certain coal pulverizer needs to add steel ball, control signal is sent by PLC, control the energising of corresponding lifting electromagnet 4 and hold steel ball, the advantage adopting magnetic to prevent other foreign material to be brought in coal pulverizer, prevents the efficiency of pulverized coal preparation system from declining.Stop above the falling sphere bucket 5 that lifting electromagnet arrives certain coal pulverizer 6, lifting electromagnet power-off, steel ball drop drives to ball mill porch along slideway 3 with micro-tilt angled down, and magnetic hangs and returns, until this adds chou bundle.Falling sphere bucket 5 bottom has flapper 7.
Slideway adopts non-ferric prepared material, in order to avoid affect magnetize to hang work.Slightly high in the middle of horizontal slide bottom, fall if any steel ball and can turn back in Ji Qiuchi or coal breakage bucket, reuse.
The foregoing is only embodiments of the invention, be not limited to the present invention.The present invention can have various suitable change and change.All any amendments done within the spirit and principles in the present invention, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
