Abstract
Manifold type comb -type machine of screening coal, wherein screen cloth by a plurality of screen traies and several screen tray axle form, the every a set of screen tray of the epaxial assembly of screen tray, the epaxial screen tray equidistance of same root screen tray, vertical fixation are epaxial at the screen tray. Parallel mount is in the frame each other in a vertical inclined plane for the screen tray axle, and an epaxial screen tray of screen tray in the adjacent screen tray axle stretches into between the epaxial adjacent screen tray of another screen tray, screen cloth actuating mechanism includes rack -mounted driving motor, speed reducer, fixes the epaxial crank at reducer output, one end connecting crank initiative connecting rod, articulate driven connection rod on the initiative connecting rod, fix at the epaxial isometric and parallel screen tray axle rocker that articulates on driven connection rod of every screen tray respectively, the utility model discloses an actively the effect is: the screen tray treats that screening material is just having, anti - coupling acts on repeatedly to getting into in the screen tray clearance, can prevent from stifled from the card. The experiment shows thoughtlessly have weeds, plastic bag, rag in the coal, and under serious viscous state appeared in messenger's coal, the screen cloth was not still blockked up.
Description
Technical field.
This utility model belongs to Work machine, is specifically related to the screen subset that thermal power plant etc. is used with coal yard
Background technology
In the past, the using coal enterprise large-scale, relatively large such as thermal power plant, the screen extension set used had swing, comb-tooth-type, roller shaft type.Above-mentioned screening machine, when sieving non-colm (ash, moisture, impurity do not exceed standard), it is possible to meet production requirement.But in China, enterprise's domestic raw coal of many uses of large-scale use coal.The irrefragable fact is that domestic raw coal generally exists that ash is many, water content is high, and is mixed with stone, wooden unit, metal derby, fabric etc..This kind of ature of coal gives the process before using, and particularly in the first screening of inclusion granule size difference big (from bulk to powder), brings many difficult problems.Using the colm that the most enterprise of existing sieving machine screening is used, the stifled sieve of viscous coal is in the field of business to be accustomed to, and rare have sieve not block up.Screen blocking disadvantage is the most serious.Making to screen coal, link production efficiency is low, power consumption is many, and equipment failure rate is high, and coal screen blocking, duff must be caused and enter coal breaker in a large number, threaten the safe operation of coal breaker.Time serious, system is closed.
Utility model content
The purpose of this utility model is to provide a kind of manifold type comb coal screen, for the screening to coal, improves screening efficiency, overcomes existing coal screen sieving the aqueous height that current China uses in a large number, the colm above shortcomings that ash is big, impurity is many.
Coal screen of the present utility model includes frame, screen cloth, screen cloth surrounding baffle, screen cloth drive mechanism, screen cloth therein is made up of multiple screen traies and several screen tray axle, assemble one group of screen tray on every screen tray axle, and the screen tray on same screen tray axle is equidistant, be vertically fixed on screen tray axle.Described screen tray axle is parallel to each other in a vertical inclined plane and is arranged in frame, and the screen tray on a screen tray axle in adjacent screen tray axle stretches between the adjacent screen tray on another root screen tray axle；Described screen cloth surrounding baffle is at least located at screen cloth both sides, described screen cloth drive mechanism includes rack-mounted driving motor, reductor, the crank being fixed on speed reducer output shaft or wheel, follower link that the drive connecting rod of one end connecting crank free end, one end are hinged on drive connecting rod free end, the isometric and parallel screen tray axle rocking bar being hinged in follower link being separately fixed on every screen tray axle, the ratio of crank therein and rocking bar length meets crank and rotates one week rocking bar in the range of set angle back and forth.
For improving screening percentage further, it is reciprocal in about angle that crank in drive mechanism and the ratio of rocking bar length meet one week rocking bar of crank rotation, described screen tray is the shape of disk about right angle portions of disappearance, screen tray lack part position on same screen tray axle is identical, the part that each screen tray is lacked swings on rear side of screen tray axle in the range of semicircle, and the circumference of screen tray presses close to adjacent screen tray axle.
For making the coal on compass screen surface obtain bigger coal flow path direction active force from screen tray circumference, it is positioned at after screen tray is installed on the circumference of upside and is distributed several ratchet.
For ease of assembling and maintenance, described crank, connecting rod are divided into two sets, and casing is stretched out at braking maneuver power output shaft two ends, often holds by shaft coupling connecting crank axle, are respectively mounted crank on two crank axles, and crank connects drive connecting rod；Being one group by rising from the odd positions screen tray axle of screen cloth either end, even number screen tray axle is one group, and the rocking bar of two groups of screen tray axles sets up separately in screen cloth both sides, and the follower link with respective side is connected respectively, two suite handles, connecting rod drive two groups of screen tray axles in the same direction, synchronous axial system.
Operation principle of the present utility model is: during screening operation, and screen cloth axle group is with same frequency, the upper and lower rotation of identical spinning movement.Enter the raw coal of coal screen, rush at highest order axle group with certain speed, after entrance tooth screen tray under fixed fingers coordinates, sieved and push coal on sieve to the way of escape.Every coal entering into the most forward and backward two between centers, under each two adjacent teeth screen tray " positive and negative coupling is repeatedly " acts on, sieves through coupling part, and coal on the sieve on coupling part is pushed to outlet.This through coupling part screening, because of in adjacent teeth screen tray coupling.Two adjacent teeth screen tray, to coal between two tooth screen traies and the necessarily balance of foreign material active force, causes thing, disk detachment, facilitates coal under gravity, and Low ESR falls.
Good effect of the present utility model is: synchronization therein, the screen tray of rotating in same direction have " positive and negative coupling is repeatedly " unique effect to the material to be sieved entered in screen tray gap, can prevent coupling locked, occur from the stifled phenomenon from card.Use circular but lack the screen tray of a right angle portions and lack part is located at institute's defined position, compass screen surface can be obtained and be alternately present scarce screen tray and without coupling unit with lower part, reduce compass screen surface with lower part saturating coal resistance.Experiment use shows, even if ature of coal is mixed with the foreign material such as weeds, plastic bag, rag, straw rope and a large amount of ash and water content reaches ature of coal and occurs that under serious viscous state, screen cloth is the most blocked.Eliminate the obstinate disease that coal screen cannot be treated in decades, its smooth and easy sieve function, improve work efficiency; the power consumption of coal screen is greatly reduced; coal screen fault is few, service life is long, protects the properly functioning of coal pulverizer, whole coal handling system is had potential economic worth.
