Description
Technical field
The utility model relates to a kind of milling apparatus, relates in particular to a kind of rod mill that is used for chemical fertilizer and the preparation of Coal Chemical Industry industry gasified coal water slurry.
Background technology
The grinding machine that is used at present comminuting matter both at home and abroad, mainly contain rod mill and ball mill, wherein, ball mill utilizes the spheroid bump to reach the effect of comminuting matter, its shortcoming mainly is can not directly produce to have the product that certain granules distributes, and usually causes wastage of material, production efficiency low in the production process; And existing rod mill, mainly utilize motor to drive the eccentricity excitation piece and produce exciting by clutch, make the related frame of cylindrical shell support next and play vibration at spring, reach crushing effect, its shortcoming is that ginseng shakes that parts are too much, shaft coupling damages easily, spring life is short, energy consumption is excessive, production efficiency is low; The rod mill that adopts spring bearing to replace original spring support cylindrical shell is also arranged, but this rod mill grinding effect is not good, and complex structure, be unfavorable for maintenance.
Summary of the invention
Technical problem to be solved in the utility model is that existing rod mill, ball mill grinding weak effect, efficient are low, complex structure, service life are short.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is: a kind of rod mill, comprise feeder, cylindrical shell, discharging portion and drive unit, also be provided with spring bearing, spring bearing is positioned at the cylindrical shell two ends, the central authorities of spring bearing are the input and output material hole, feeder, discharging portion is positioned at two outsides of spring bearing respectively, drive unit drives the cylindrical shell rotation, also is provided with grinding rod and liner plate in the cylindrical shell, and liner plate is embedded on the cylinder inboard wall, described discharging portion is a rotary screen, be provided with coarse granule chute and coal slurry tank diameter in the rotary screen, rotary screen one end connects spring bearing, and the other end is provided with electronic from rod adding device.
The rod mill main working parts is a cylindrical shell, spring bearing generally adopts hybrid sliding bearing, during work, when feed coal, water, additive are fed in the cylindrical shell by feeder, drive unit drives the cylindrical shell rotation that grinding rod is housed, feed coal grinds between grinding rod and shell liner, the coal slurry outflow cylindrical shell that is formed after grinding enters the rotary screen with the cylindrical shell rotation, impurity and coarse granule are that oversize advances the coarse granule chute, the finished product water-coal-slurry is that screenings advances the coal slurry tank diameter, reach separating effect preferably, reduce the possibility of running slurry.In addition, rod adding device adopts the existing electronic bar mode that adds, and rod iron is placed on the support roller of V-shaped groove, and the support roller group is driven by reducing motor, belt wheel gearing, makes rod iron moving linearly forward, is admitted in the cylindrical shell, and the rod adding device top is provided with leads bar device.If electronic automatic rod adding device can alleviate working strength of workers greatly, provide and adorn excellent efficient.
Install and maintenance for convenient, also be provided with U font top tank arrangement, the spring bearing at cylindrical shell two ends is held at the two ends of described top tank arrangement respectively.The top tank arrangement holds up whole cylindrical shell, for reserving enough big space for installing, overhauling in the cylindrical shell below.
For guaranteeing product with compact structure, optimize the transmission layout pattern, described drive unit is positioned at cylindrical shell inboard (Fig. 2 bottom), drive unit comprises motor, shaft coupling, decelerator, pneumatic clutch, driven wheel and the travelling gear that connects in turn, and described travelling gear is positioned at the spring bearing inboard of cylindrical shell feeder one side.
Be the protection drive unit, prolong the service life of drive unit, described drive unit also is provided with high-pressure lubricant pump, and described high-pressure lubricant pump links to each other with motor.Before starting drive unit, start high-pressure lubricant pump earlier, can prevent to abrade bearing shell.
Be anti-antiemetic material, described feeder comprises charging aperture and elephant trunk, described elephant trunk inner liner abrasive resistant material.The conventional wet grinding machine adopts the feeding manner of cydariform dispenser, because the rod mill rotational speed rate is low, the rod mill rotating speed of maximization is lower, therefore tell material easily, according to the characteristics of charge raw material coal, coal pulverizer adopts the elephant trunk of inner liner abrasive resistant material directly to be fed into cylindrical shell, can eliminate this shortcoming.
As a kind of improvement project of the present utility model, described liner plate is a steel liner plate.Cylindrical shell adopts the steel liner plate of water-coal-slurry coal pulverizer special use, can prevent disorderly rod and disconnected rod, and improve grinding efficiency.
Advantage of the present utility model is: grinding, good separating effect, production efficiency height, simple in structure, long service life.
