A kind of anti-windrow ball mill
Technical field
The utility model relates to a kind of ball mill, and particularly a kind of anti-windrow ball mill, belongs to Machine Design manufacturing technology field.
Background technology
Ball mill is grinding machinery important in the enterprise such as cement, mineral products, and it grinds raw material as steel ball, rod iron etc. by swing roller and interior abrasive media thereof. Because swing roller is made up of the end cap at cylindrical tube and two ends, this just easily forms the angle of 90 degree between end cap and cylinder two ends, and this angle is the dead angle that steel ball, rod iron are difficult to touch. This just causes material easily in this angle, to form and pile up, and not only can waste material, and easily affect the operating efficiency of ball mill at the long-term stacking material in dead angle place, and increase its consumption to the energy, is unfavorable for energy-saving and cost-reducing principle. In addition, if ball mill is changed other material, can make the material being detained sneak in the material newly adding and form impurity, thereby affect the quality of new material. Therefore be necessary prior art to be improved.
Summary of the invention
Be prone to dead angle for solving existing ball mill swing roller content, make material form and pile up at dead angle place, affect ball mill operating efficiency and increase the problems such as energy consumption, the utility model provides a kind of anti-windrow ball mill.
The utility model completes by following technical proposal: a kind of anti-windrow ball mill, comprise frame, and be located at the cylindrical shell in frame, cylindrical shell one end is that charging aperture, the other end are discharging opening, it is characterized in that being provided with its inner in cylindrical shell and be equipped with the pipeline of nozzle, this pipeline outer end is connected with outside pneumatic plant through the discharging opening of cylindrical shell, to carry compressed air by pneumatic plant to the pipeline in cylindrical shell, again by nozzle by blast injection to the windrow place in cylindrical shell, material is dispelled, prevent solid accumulation.
Described pipeline is made as horizontal pipe, the inner interval of this horizontal pipe arranges at least two VERTICAL TUBE, nozzle is all established in each root VERTICAL TUBE upper end, this horizontal pipe outer end is connected through the discharging opening of cylindrical shell and the vertical arm lower end of outside, vertically arm upper end is connected with air supply header, air supply header is connected with pneumatic plant, to carry compressed air by pneumatic plant, air supply header to vertical arm, horizontal pipe, VERTICAL TUBE, nozzle.
Described VERTICAL TUBE between two shifts to install, nozzle in VERTICAL TUBE arranges in opposite directions between two, and the angle between nozzle is 5-30 degree between two, so that nozzle is in opposite directions and the correlation that misplaces between two when jetting compressed air in cylindrical shell, non-interference in the situation that, form regions of turbulent flow, thoroughly eliminate dead angle windrow phenomenon.
Described vertical arm is provided with by-pass valve control.
The charging and discharging mouth at described cylindrical shell two ends is provided with end plate, and charging and discharging mouth outside is arranged in frame by bearing and bearing block respectively.
On described cylindrical shell, be respectively equipped with gear ring and slipping ring, gear ring is meshed with driving gear, and driving gear is connected with electric machine main shaft, and slipping ring is placed in and supports on pulley, so that under driven by motor, drives barrel body rotation.
The utlity model has following advantages and effect: adopt such scheme, can be easily by being arranged on the compressed air hose with nozzle in ball mill barrel, make ball mill in the time of running, incessantly to carrying compressed air in it, under the effect of jet-stream wind, not only can make the mixing of materials in it more even, and the most important thing is to avoid material to pile up at cylinder dead angle place by the injection of air-flow. Not only improve the operating efficiency of ball mill, and can reduce ball mill power consumption, played energy-saving and cost-reducing effect, effectively prevented from changing the problem of mixing that material brings, be conducive to improve the quality of products simultaneously. Be a desirable ball mill in fact.

Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further.
The anti-windrow ball mill that the utility model provides, comprise frame 1, and be located at the hollow cylinder 5 in frame 1, hollow cylinder 5 left ends have charging aperture 3, right-hand member to have discharging opening 11, on charging and discharging mouth 3,11, be respectively equipped with end plate 2,12, and charging and discharging mouth 3,11 outsides are arranged in frame 1, wherein by bearing and bearing block 4 respectively: in hollow cylinder 5, be provided with its inner and be equipped with the pipeline 9 of nozzle 7, these pipeline 9 outer ends are connected with outside pneumatic plant through the discharging opening 11 of cylindrical shell 5; Described pipeline 9 is made as horizontal pipe, the inner interval of this horizontal pipe arranges two VERTICAL TUBE 10, nozzle 7 is all established in each root VERTICAL TUBE upper end, this horizontal pipe outer end is connected with vertical arm 14 lower ends of outside through discharging opening 11 and the end plate 12 of cylindrical shell, vertically arm 14 upper ends are connected with air supply header 8, and air supply header 8 is connected with pneumatic plant (not providing in figure); Described VERTICAL TUBE between two 10 shifts to install, nozzle 7 in VERTICAL TUBE 10 arranges in opposite directions between two, and the angle between nozzle 7 is 20 degree between two, so that nozzle 7 is in opposite directions and the correlation that misplaces between two during to the interior winding-up compressed air of cylindrical shell 5, non-interference in the situation that, form regions of turbulent flow, thoroughly eliminate dead angle windrow phenomenon; Described vertical arm 14 is provided with by-pass valve control 13, to control compressed air pressure, flow; On described cylindrical shell 5, be respectively equipped with gear ring 15 and slipping ring 6, gear ring 15 is meshed with driving gear 16, and driving gear 16 is connected with motor 17 main shafts, and slipping ring 6 is placed in and supports on assembly pulley 18, under motor 17 drives, drive cylindrical shell 5 to rotate.
When work, carry compressed air by pneumatic plant, air supply header 8 in cylindrical shell 5 to vertical arm 14, horizontal pipe 9, VERTICAL TUBE 10, by nozzle 7, blast injection is arrived to the windrow place in cylindrical shell 5 again, material is dispelled, prevent solid accumulation, and can adjust compressed air pressure, flow according to windrow situation, dispel as far as possible material.
