Abstract
The utility model relates to a dovetail groove sleeve-type automatic removing device, and relates to a ball grinding mill, in particular to an automatic removing device for automatically removing small steel balls which are disqualified due to abrasion during the operation of the ball grinding mill, and solves the problems that the known ball grinding mill has certain requirements for the size of steel balls, the output of the ball grinding mill is impacted when abraded steel balls are not removed, and when the abraded steel balls are removed, a feed port is required to be dismantled under the shutdown state, so that certain difficulties are brought, and the working capacity is large. The removing device comprises a cylinder body, a wavy lining board, an end lining board and an outlet screw shell, and is characterized in that a dovetail groove is formed on the end lining board, and sleeves are arranged between the cylinder body and the end lining board as well as between the cylinder body and the outlet screw shell; ball outlet grooves are formed on the sleeves and the cylinder body, and ball retaining rings are fixed on the cylinder body along the circumferences of the ball outlet grooves; and ball outlet holes corresponding to the ball outlet grooves are formed on the ball retaining rings. During the operation of the ball grinding mill, the unqualified steel balls due to abrasion can be discharged from the ball grinding mill automatically, so as to ensure the output of the ball grinding mill, and reduce the power consumption.
Description
Technical field
The utility model relates to a kind of ball mill, relates in the automatic improvement cleaning ball mill automatic cleaning apparatus because of use, the defective small ball of wearing and tearing specifically.
Background technology
Ball mill is a kind of low speed material disintegrating apparatus, and rotating speed is generally 15-25r/min, is widely used in industries such as coal-burning power plant, cement, ore dressing.Its working portion is a diameter 2-4 rice, the cylinder of long 3-10 rice, and it is 25-60 centimetre steel ball that a large amount of diameters are housed in the tube; Cylinder inboard wall lining dress undaform manganese steel armor.Its operation principle is, stack shell drags rotation by gearings such as motor, reductors, and steel ball is taken to certain altitude by armor, falls then, by the bump between steel ball and the cylindrical shell, push, roll etc., with the material fragmentation.The steel ball of ball milling internal stowage influences directly that fragmentation is exerted oneself and power consumption, so the useful load of steel ball, ball size have certain requirement.According to the ball mill service requirement, because steel ball in running, exists wearing and tearing, loss, exert oneself in order to guarantee the best, need the regular replenishment steel ball; To because of causing underproof small ball after the wearing and tearing, to regularly clear up after every operation a period of time.But in the actual motion, if will clear up small ball, need outaged equipment, remove the ball mill feeding mouth, whole steel balls are got rid of elect, again steel ball is returned dress after cleaning out small ball, have certain difficulty and workload.Therefore the periodic cleaning small ball is difficult to accomplish.
Summary of the invention
The purpose of this utility model is at above-mentioned deficiency, and a kind of ball mill that proposes cleans out the underproof small ball in wearing and tearing back automatically in running, and the guarantee ball mill is exerted oneself, and reduces the telescopic automatic cleaning apparatus of dovetail groove of power consumption.
Technical solution of the present utility model is: telescopic automatic cleaning apparatus comprises cylindrical shell, ripple liner plate, aside-liner and outlet screw shell, it is characterized in that: aside-liner is provided with dovetail groove, is provided with sleeve between cylindrical shell and the aside-liner and between cylindrical shell and the outlet screw sheel; Sleeve and cylindrical shell are provided with out the ball groove, and along being fixed with the circle of blocking on the cylindrical shell that goes out ball groove circumference, the circle of blocking is provided with and goes out the corresponding spherical cavity of ball groove.
Be fixed with out bulb on the spherical cavity of the circle of blocking described in the technical solution of the present utility model.
The utility model was not shut down in ball mill in service needs; the underproof small ball in the wearing and tearing backs dovetail groove from the aside-liner automatically spills, and discharges outside the ball mill by going out the ball groove and going out bulb again, has therefore guaranteed the size of steel ball in the ball mill; guarantee exerting oneself of ball mill, reduced power consumption.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structure for amplifying schematic diagram of aside-liner among Fig. 1;
Fig. 3 is the structure for amplifying schematic diagram of blocking among Fig. 1 and enclosing.
The specific embodiment
As shown in Figure 1, 2, 3, ball mill mainly comprises cylindrical shell 1, ripple liner plate 2, aside-liner 3 and outlet screw shell 6, ripple liner plate 2 is fixed on the inboard of cylindrical shell 1, aside-liner 3 is fixed on the port of export of cylindrical shell 1 by bolt assembly 4, aside-liner 3 is provided with dovetail groove 11, the width of dovetail groove 11 is less than the diameter of ball mill steel ball, the underproof small ball in wearing and tearing back is passed through, and the steel ball of normal size can not pass through, therefore in the process of ball mill operation, cause underproof small ball from this dovetail groove 11, to spill after being worn; Between the cylindrical shell 1 in aside-liner 3 and its outside, and be provided with sleeve 7 between outlet screw shell 6 and the cylindrical shell 1, on the sleeve 7 in ball mill outlet screw shell 6 outsides and cylindrical shell 1, leave out ball groove 8, along being fixed with the circle 10 of blocking on the cylindrical shell 1 that goes out ball groove 8 circumference, the circle of blocking leaves on 10 and goes out ball groove 8 corresponding spherical cavities 12, block and adopt asbestos cord or asbestos board sealing between circle 10 and the cylindrical shell 1, on the circle 10 of blocking, be connected with out bulb 9, block to enclose on 10 and leave spherical cavity 12, going out bulb 9 is connected on the spherical cavity 12 of circle on 10 of blocking, in sleeve 7, be fixed with a baffle ring 5, baffle ring 5 is located at a side of outlet screw shell 6 outlets, when ball mill is worked, underproof small ball spills from the dovetail groove 11 on the aside-liner 3, fall in the sleeve 7, blocked, force small ball to discharge from the ball groove 8 that goes out on sleeve 7 and the cylindrical shell 1 by baffle ring 5, enter the circle 10 of blocking from the small ball that goes out 8 discharges of ball groove, the spherical cavity 12 from the circle 10 of blocking enters out outside the bulb 9 discharge ball mills again.
