Description
Technical field
The utility model relates to the equipment for preparing water-coal-slurry, particularly about a kind of rod mill that is applicable to that water-coal-slurry grinds.
Background technology
Traditional water-coal-slurry preparation ball mills that adopt utilize the mode of wet grinding mill that lump material is ground more.Be with coal, water and dispersant feed by a certain percentage by screw(-type) feeder, ball mill grinding is pulverized and is made slurry, abrasive media adopts steel ball, can make the slurry that grinds out have certain deposition efficiency and size distribution, thereby obtain having higher concentration, coal, the water fluid-mixing of certain viscosity and good rheological characteristic.But it is the motion mode of the formula of leaving that abrasive media (steel ball) has quite a few, and promptly abrasive media leaves after being risen to certain altitude by lining board of grinder, by the impulsive force comminuting matter.This motion mode makes a big chunk energy dissipation on the steel ball impact grinding, causes the capacity usage ratio of ball mill very low, finally causes a ton slurry power consumption high.In addition, along with DEVELOPMENT OF COAL-WATER SLURRY TECHNOLOGY, the variation of especially slurrying coal, depend merely on a kind of type grinding of ball mill and can not obtain rational size distribution, therefore, the water-coal-slurry product that adopts high deposition efficiency of two grinding process (corase grind+fine grinding) combined preparation and fine granularity to distribute has become the trend of following water-coal-slurry development.
Summary of the invention
At the problems referred to above, the utility model purpose provides a kind of rod mill that is applicable to water-coal-slurry preparation, and this rod mill has grinding efficiency height, characteristics that energy consumption is little.
For achieving the above object, the utility model is taked following technical scheme: a kind of water-coal-slurry rod mill, comprise bearing, revolving drum, batcher, transmission device, it is characterized in that: described revolving drum passes through two bearing brackets on described bearing, be arranged with the driven gear of described transmission device on the outer wall of described revolving drum, described batcher connects the feed inlet end of described revolving drum; The attached waveform shell liner that is lined with is loaded with some cylindrical grinding rods in described revolving drum inside on the described revolving drum inwall; Described transmission device comprises motor, speed changer and gear train.
Described shell liner is fixed on the inwall of described revolving drum by several screws of squeezing into outside revolving drum, and the inner surface of described shell liner is the waveform face.
Described shell liner is a steel plate.
The cylindrical shell two ends of described revolving drum are connected respectively a hollow shaft, two described hollow shafts all are located on the described bearing block by bearing, the described hollow shaft of one end is as the feed inlet end of described revolving drum, and the described hollow shaft of the other end is as the discharge port end of described revolving drum.
Described grinding rod is elongated cylinder rod iron, than the short 10～20cm of cylindrical shell.
The barrel top of described revolving drum offers the repair operation mouth.
Described gear train is intermeshing multi-stage gear combination.
The utility model is owing to take above technical scheme, it has the following advantages: 1, the utility model adopts rod iron as abrasive media, rod iron is done the roller motion in revolving drum, changed the motion mode of original impact grinding, significantly reduce because the energy dissipation that mill Jie impact grinding is brought, improve the capacity usage ratio of grinding machine, reduced the slurrying power consumption.2, the utility model adopts the wave steel liner plate to replace rubber lining, reduces owing to the infringement of " disorderly rod " phenomenon to liner plate.And the wave liner plate can increase the rolling power of rod iron, increases the impact between rod iron and the material.3, improve the rotating speed of revolving drum, can increase the grainding capacity of rod mill greatly, and, when improving output, can effectively reduce power consumption of the mill owing to improved the specific energy of rod mill.4, at the grinding machine charging aperture water slurry import is set, makes water slurry enter grinding machine, between grinding rod and coal charge, form " lubricating " effect, reduce the milling time of grinding machine, further reduce the slurrying power consumption.

The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in detail.
As shown in Figure 1, 2, the utility model mainly comprises revolving drum 1, grinding rod 2, bearing 3, batcher 4, transmission device more than 5 parts.
Shown in Fig. 1,3, revolving drum 1 comprises cylindrical shell 11, shell liner 12, charging aperture 13 and discharging opening 14.Be provided with shell liner 12 in the inside of cylindrical shell 11, the outer surface of shell liner 12 is the smooth face of cylinder, inner surface is concavo-convex waveform face, when shell liner 12 places cylindrical shell 11, the attached lining in the smooth face of cylinder that makes shell liner 12 by several screws of squeezing into outside cylindrical shell is on the inwall of cylindrical shell 11, and cylindrical shell 11 just makes the inwall of whole revolving drum 1 present the regular concavo-convex surface of revolution with combining of shell liner 12.Here, shell liner 12 is generally selected steel plate for use.Certainly, cylindrical shell 11 also can be integral production spare with shell liner 12, but because shell liner 12 is the friction consumable accessory in revolving drum inside, if integral production, shell liner 12 will be changed with cylindrical shell 11 during replacing, certainly will cause waste of material like this.
Naturally be connected a hollow shaft 15,16 that shrinks respectively from the both ends of cylindrical shell 11, these two hollow shafts can be to be shunk naturally by cylindrical shell 11 ends, and are integrated with cylindrical shell 11; Also can be after making separately, pass through welding or bolted with the end edge of cylindrical shell 11.The port of hollow shaft 15,16 is exactly respectively the charging aperture 13 and the discharging opening 14 of revolving drum 1.
Also offer the convenient gathering hole 17 of observing, repairing at the barrel top of revolving drum 1.In the inside of revolving drum 1, be placed with described grinding rod 2, grinding rod 2 is elongated cylinder rod iron, generally than the short 10～20cm of cylindrical shell.
The gyration of revolving drum 1 is driven by transmission device 5, and transmission device 5 comprises motor 51, speed changer 52 and driving gear set 53, and wherein, the driven pulley 54 in the driving gear set 53 is socketed on the revolving drum 1.
During work, make revolving drum 1 rotation,, fill grinding rod 2, filling rate 〉=50% in the cylindrical shell Yi Bian by batcher semi-finals system feed, material feeds inner barrel by charging aperture 13 Yi Bian start transmission device 5.Because inner barrel is the waveform liner plate, when revolving drum 1 running, grinding rod 2 is mainly done the motion of landing formula, therefore material is subjected to reaching between the grinding rod medium grinding between medium and the shell liner, reach the material of release mesh, discharge, finish process of lapping through discharging opening 14.Simultaneously, improve mill speed, can strengthen the grainding capacity of grinding machine, improve pulverizer adequacy.
What deserves to be explained is; the foregoing description only is used to illustrate the utility model; wherein the structure of each parts, connected mode etc. all can change to some extent; every equivalents of carrying out on the basis of technical solutions of the utility model and improvement all should not got rid of outside protection domain of the present utility model.
