Description

The ball mill marble feeding device
Technical field
It is mechanical that the utility model belongs to, specifically a kind of machine that grinds with steel ball that adds in the ball mill.
Background technology
With ball mill lump coal being worn into coal dust, is to add steel ball to rotate in the ball mill of lump coal is housed, and finishes by each other collision, friction and extruding.In the process of grinding, steel ball and lump coal collision on the one hand, friction and extruding, bump and extruding mutually also can take place between steel ball and the steel ball simultaneously, the factor of two aspects diminishes worn steel ball and loses abrasive action to lump coal gradually, need regularly or irregularly to add new steel ball for this reason and replenish its useful load, thereby ball mill is moved, under the operating mode of best useful load of steel ball and best proportioning to guarantee milling efficiency the best.
As the power plant coal dust, generally be to adjust the ball amount that adds by ton coal metal consumption.With the DTM350/600 ball mill is example, and per hour powder process is 30 tons, ton coal metal consumption 80-150 gram, every day is by running 16 hours, day metal consumption 72Kg, must add 40-85 heavy 887 grams/steel ball.Bad or ature of coal is relatively poor as steel ball quality, then worn steel ball can be bigger, must add the filling optimum value that more steel balls guarantee steel ball in the ball mill, and ball mill could move under optimum condition.
Add steel ball in ball mill, at present the mode that attaches that adopts is that steel ball is transported to ball mill nearby, again with steel ball handling to 79 meters-9 meters high add the ball platform, manually pour the inlet duct of ball mill into.Like this, big to pipeline, the solenoid wearing and tearing of ball mill inlet and impact when steel ball falls at a relatively high speed from the higher position, so descend service life; Simultaneously when steel ball enters ball mill at a relatively high speed, because steel ball impacts mutually and very easily damage when colliding even break.Rule of thumb, when the proportioning ratio of steel ball in the ball mill and coal was better, the steel ball of cylindrical shell implosion owing to impact mutually when adding steel ball and cause, also had bigger infringement to shell liner more than 60% simultaneously, causes descend its service life.
The utility model content
Technical problem to be solved in the utility model is, overcome in the prior art and with manually from eminence toward ball mill, add ball, steel ball falls and to cause descend service life to ball mill and pipe wear, impact, and the shortcoming of the mutual concussion fracture coal-grinding of steel ball weak effect, a kind of ball mill marble feeding device is provided.
In order to solve the problems referred to above that prior art exists, the utility model is to adopt following technical proposals to realize: marble feeding device is formed with ball cabinet and the transmitting device that transports steel ball by storing steel ball; Described transmitting device comprises group ball roller that is docked at the ball cabinet outlet, and is connected on the vertical ring conveyor chain of dialling ball roller ball mouth, can phoresying steel ball; Following commentaries on classics place at chain is connected under the chain turning, and the goal groove that joins with the ball mill ball hole is installed.
The utility model also has following key character:
The described vertical ring conveyor chain that phoresys steel ball is on the outer ring surface of chain, is distributed with a plurality of dress ball buckets that rotate, the steel ball of dialling the dial-out of ball roller can be packed into chain;
Described group of ball roller is made up of drive roll and driven voller, and the gear on the drive roll is by the gears engaged on mesomerism gear and the driven voller, is provided with protruding helix at the roll surface of drive roll, and the roll surface of driven voller is provided with the recessed helix reverse with protruding helix;
The ball mouth of described group of ball roller is to be combined by relative annular concave arc groove on drive roll and the driven voller;
The ball mouth of described group of ball roller is located at an end of dialling the ball roller;
The ball mouth of described group of ball roller is located at the centre of dialling the ball roller;
The ball mouth of described group of ball roller is located at the two ends of dialling the ball roller;
The diameter of described driven voller is greater than the diameter of drive roll;
The Cang Gai that is equipped with suitable for reading of described ball cabinet, the bottom surface, storehouse is the wedged bottom that tilts to its Way out;
Described ball cabinet be suitable for reading add a cover can be closed.
When ball mill needs tip-in, start and dial ball roller and conveyor chain rotation, dialling under the stirring of ball roller of rotating, steel ball is rolled on group ball roller from the outlet of ball cabinet, be rolled into its ball mouth along the helix on the roller, drop to again on the annular conveyor chain that is connected under it in one of a plurality of dress ball buckets, when the dress ball bucket that steel ball is housed goes to transmission frame top downwards in the time will changeing, the goal groove that ball inclines and to fall into to be connected on the ball mill ball feeding mouth from dress ball bucket, the whole process that adds steel ball in the ball mill is promptly finished.
If equipped with microcomputer self-control system on the marble feeding device, start ball adding device after only needing that input is corresponding on control corresponding is strong and adding the nodule number amount, can add by setting quantity.When the ball that adds reaches this quantity, equipment will stop automatically, and can write down total ball amount that adds in a period of time.Operated from a distance is realized in microcomputer automatic control control section access operation chamber.
Advantage of the present utility model and good effect are, utilize ball cabinet and the transmitting device that steel ball is housed on the ground is installed, without collision is delivered directly to high-order ball mill ball feeding mouth with steel ball, it is little to add the ball drop, can avoid to greatest extent adding the infringement that ball causes to ball mill and pipeline and steel ball because of a high position, also save the raw material of making steel ball, reduced cost; When the ball mouth of dialling the ball roller is located at the two ends of dialling the ball roller, can realize that an equipment adds ball to two table grinders; Use described marble feeding device accurately to control and add the ball time and add the ball amount; Ball cabinet is sealed, can realize effective management effectively, guarantee out the balance of warehouse-in the steel ball amount.This device structure is simple, and is easy to operate.
