Specific implementation mode
Further to illustrate that the utility model is to reach the technological means and effect that predetermined goal of the invention is taken, below
In conjunction with attached drawing and preferred embodiment, to according to the utility model proposes a kind of ball mill grinding body sorting system its specific implementation
Mode, structure, feature and its effect are described in detail as after.
Referring to Fig. 1, a kind of ball mill grinding body sorting system includes ball device 1, conveying device 2, sorting equipment 3,
The effect of ball device 1 is to summarize the abrasive body A that ball mill 4 is thrown away and be exported from same outlet to conveying device 2, conveying
The effect of device 2 is abrasive body A being promoted to after certain altitude is transported to sorting equipment 3 by the inertia of abrasive body A
Interior, the effect of sorting equipment 3, which is to sort abrasive body A according to different size, to be stored.
Ball device 1 is assembled by two plates of falling ball 101, and 101 bottom of one of them plate of falling ball is equipped with targeting port 103,
It is slided out in conveying device 2 convenient for the abrasive body A in ball mill 1.Please refer to Fig. 2, the ball device 1 is sleeved on ball milling
It the outside of machine 4 and is connected by flexible seals 5 therebetween, three forms a confined space, the grinding door 401 of ball mill 4
In the confined space.When ball mill 4 rotates, abrasive body A is thrown away from grinding door 401, is touched after the plate of falling ball 101 along the plate of falling ball
101 inner wall, which glides, to be collected, and is finally skidded off from targeting port 103, to avoid abrasive body from being thrown to workshop elsewhere；While by
The presence of flexible seals 5 prevents the powder in ball mill 1 from escaping pollution workshop condition in the collection of falling ball.In the collection of falling ball
During, the rotation of ball mill 4 (is realized) that ball device 1 is not rotated by dynamical system driving transmission gear 402, it is therefore desirable to
It will ball device 1 be mounted on two the first supporting racks 6.
Specifically, the section semicircular in shape of each plate of falling ball 101, two end convex are equipped with method in the present embodiment
Flange aperture, bolt 102 is affixed with flange hole cooperation two plates of falling ball 101 of realization, but the utility model does not limit the plate of falling ball 101
Shape and erection method.
Conveying device 2 uses ribbon conveyer, conveyer belt to be divided into straight section 201, oblique section 202, straight section 201 (preferably middle part)
Immediately below the targeting port 103 of ball device 1, the abrasive body that oblique section 202 is used to skid off targeting port 103 promotes certain height
Degree, one of reason are ball mill 4 when mounted, and grinding machine center line is 0.8-1.0D (D is ball mill diameter) away from ground level,
Grinding mill barrel bottom is 0.3-0.5D away from ground level, such as a diameter of 4 meters of grinding machine, cylinder bottom far from ground namely
2 meters, space is inadequate, it is therefore desirable to the abrasive body that ball device 1 is collected be mentioned certain altitude, then sorted；The two of reason
It is abrasive body A being promoted to certain altitude, need to only designs the speed and conveying device 2 and sorting equipment 3 of ribbon conveyer
The distance between, abrasive body A can be conveyed into sorting equipment 3 by the parabolic path of abrasive body.
Sorting equipment 3 includes rotatable cylindrical tube 301, the peak of the oblique section of cylinder 301 and ribbon conveyer 202
Between have certain distance, the abrasive body A for being sent to peak is delivered in cylinder 301 by inertia.On the inner wall of cylinder 301
Equipped with spiral lifting blade 303, spiral lifting blade 303 can not only take abrasive body A to certain altitudes under the drive of transmission shaft 304
It falls again, extends screening length, improves screening efficiency, and abrasive body A can be pushed to travel forward.Fig. 3 A, Fig. 3 B are please referred to,
Cylinder 301 is divided into different sorting area (such as A1, A2, A3, A4) in an axial direction, and corresponding different sorting area is in cylinder 301
The outer circular direction of outer wall upper edge offer circular hole 3011 or the comb hole 3012 of different-diameter, the abrasive body of certain diameter moves to pair
It can be fallen to from circular hole 3011 or comb hole 3012 when the sorting area answered in the collecting box 305 of 301 lower section of cylinder.
As the further improvement of the utility model, referring to Fig. 4, sorting equipment 3 further includes outer cover 302,302 sets of outer cover
Mounted in 301 outside of cylindrical tube and on two the second supporting racks 306, the bottom of the outer cover 302 is provided in the axial direction with
Straight slot 3021 (i.e. the section of outer cover 302 is not a complete circle), the positioned beneath of the straight slot 3021 has outside collecting box 305.
302 dustproof effects are covered, prevent the dust that abrasive body A is carried is secondary in sort process from raising.
As the further improvement of the utility model, corresponding number can be arranged according to the quantity of sorting area in collecting box 305,
There are one ensureing below a sorting area；One can also be only arranged, in the inside of collecting box 305 according to the number of sorting area
Amount forms multiple collection spaces by partition board.
Specifically, the width of collecting box 305 should be greater than the width of straight slot 3021, one of benefit is to ensure from circular hole
The 3011 or abrasive body A that falls of comb hole 3012 is all fallen in collecting box；The two of benefit are the work in spiral lifting blade 303
Outer cover 302, then edge can be first touched if even if being thrown away from the circular hole 3011 of eminence or comb hole 3012 with the rising of lower fraction abrasive body
The inner wall downslide of outer cover 302 is fallen to from straight slot 3021 in collecting box 305.
It is a kind of common technique that transmission shaft 305, which is driven by dynamical system and then drives the rotation of cylindrical tube 301, no longer superfluous
It states.
A kind of operation principle of ball mill grinding body sorting system of the utility model is as follows：
When use for a long time needs to replace abrasive body, ball mill 4 rotates, and abrasive body A throws away from grinding door 401, touches
Along the shell downslide collection of ball device 1 after tactile ball device 1, the transmission belt of conveying device 2 is finally snapped down to from targeting port 103
On straight section 201.Ribbon conveyer starts, and abrasive body A is carried under the action of transmission belt 2 to the peak of oblique section 202, by inertia
Abrasive body A is delivered in the cylinder 301 of sorting equipment 3.Cylinder 301 rotates, the abrasive body under the promotion of spiral lifting blade 303
A moves to different sorting areas, and the abrasive body of different-diameter is fallen from the through-hole 3011 of corresponding sorting area or comb hole 3012
In to corresponding collecting box 305, the final efficient sorting for realizing abrasive body.
The above descriptions are merely preferred embodiments of the present invention, and any person skilled in the art is not
It is detached within the scope of technical solutions of the utility model, according to the technical essence of the utility model any letter made to the above embodiment
Single modification, equivalent variations and modification, are still within the scope of the technical solutions of the present invention.
