Abstract
The invention provides a self-locking lining board device of a horizontal roller mill. The self-locking lining board device of the horizontal roller mill comprises a fixed check ring, a plugging block, a self-locking lining board (1) and a self-locking lining board (2). The external circular arc surface of the fixed check ring is rigidly connected together with an internal wall of a barrel of the horizontal roller mill; and the wedged plugging block is arranged between each self-locking lining board and the fixed check ring. The self-locking lining board (1) and the self-locking lining board (2) are engaged mutually through respective structures per se to realize radial locking; and the self-locking boards are tightly stuffed up and fixed in an axial direction by the wedged plugging block and the fixed check ring. The disadvantage that the overall performance of the device is damaged by a countersunk bolt hole which is arranged in the lining board in the traditional design is overcome; powder grinding efficiency of the device is increased; the overhaul period is prolonged greatly; and the safe operation of the device is realized.
Description
Technical field
The roller that the present invention relates to crouch grinds, particularly a kind of roller mill self-locking liner plate device for sleeping in.
Background technology
At present, the roller mill for sleeping on the market, its liner plate all links fixing with cylindrical shell through high-strength bolt, and there is following shortcoming in design like this:
1, on liner plate, offers the dormant bolt hole; Can not counterbore all be full of because of bolt tail during work; Filling place does not form the blocked up bed of material, and this place's material can not get fully extruding and pulverizes, and has reduced system's mill efficiency; The counterbore place is exposed to outer bolt tail serious wear simultaneously, has shortened the time between overhauls(TBO) greatly;
2, because of offering screwed hole at cylinder inboard wall, infringement cylindrical shell overall structure performance;
3, the pressure that pressure roller puts on material bed in the course of work acts on liner plate and the attachment bolt through the bed of material repeatedly; Certainly will cause liner plate and bolt plastic deformation; Increase liner plate and bolt and changed difficulty, in most cases had only and adopt destructive the replacing, very only injured grinding mill barrel sometimes.
Summary of the invention
Technical problem to be solved by this invention is, to the deficiency of prior art, a kind of novel roller mill lining panel assembly for sleeping in is provided; Be meshing with each other through the liner plate self structure; Realize locking radial, overcome the defective of on liner plate, offering the dormant bolt hole in the traditional design and destroying the equipment overall performance, improved the mill efficiency of equipment; Prolong the time between overhauls(TBO) greatly, realized the device security operation.
The technical scheme that the present invention is adopted for its technical problem of solution comprises: fixedly back-up ring, wedge chock, self-locking liner plate (), self-locking liner plate (two).
Fixedly back-up ring is the inside and outside circle globoidal structure, its exterior arc surface with horizontal roll grinding cylinder inwall rigidity ground be linked together.Fixing back-up ring last week to offering a plurality of waist through hole equably, the quantity in waist hole equates that with circumferential liner plate quantity the waist through hole diameter is identical with self-locking liner plate side screwed hole diameter, and its center is on same line.
The wedge chock is the inside and outside circle globoidal structure, and its external diameter is less than the grinding mill barrel internal diameter, and internal diameter is greater than self-locking liner plate inner arc surface diameter; Every wedge chock has tapped through hole at its arc surface middle part; Near a fixing side of back-up ring, its surface is processed to an inclined-plane at input and output material end wedge chock, and the span of its gradient is 1～5 °.
Self-locking liner plate (one) is the circular arc liner plate; Its external diameter equates with the horizontal roll grinding cylinder internal diameter; The thickness of liner plate is between 50～150 ㎜, and every block self locking liner plate () two ends are respectively equipped with groove and convexity, the convexity of a liner plate and the mutual matched in clearance of adjacent liner plates groove; Self-locking liner plate (one) has the certain depth screwed hole near the side of grinding mill barrel charging and discharging end; The axial width of self-locking liner plate () is less than wedge chock axial width.
Self-locking liner plate (two) is the circular arc liner plate; Its external diameter equates with the horizontal roll grinding cylinder internal diameter; The thickness of liner plate is identical with self-locking liner plate (), and every block self locking liner plate (two) two ends are respectively equipped with groove and convexity, the convexity of a liner plate and the mutual matched in clearance of adjacent liner plates groove; Every block self locking liner plate (two) has the certain depth screwed hole near the side of horizontal roll grinding cylinder charging and discharging end respectively from the cylindrical shell axial centre.
Fixedly the back-up ring exterior arc surface with horizontal roll grinding cylinder inwall rigidity ground be linked together, the wedge chock places with the self-locking liner plate and fixedly between the back-up ring.
After the one all liner plate installations of grinding mill barrel inwall, the convexity through last liner plate is meshing with each other with the groove of back one liner plate, is locked each other radially realizing; The wedge chock places with the self-locking liner plate and fixedly between the back-up ring, axially self-locking liner plate jam-pack is being fixed.Because radially, axially all position, guarantee the security of equipment operation during work, eliminated the defective of on liner plate, offering the dormant bolt hole in the traditional design and destroying the equipment overall performance, improved the mill efficiency of equipment.The inclined design of wedge chock has made things convenient for the wedge chock to fill in or take out simultaneously, axially also more is being prone to self-locking liner plate jam-pack to be fixed liner plate generation axial motion phenomenon when having eliminated the grinding machine operation.Wedge chock inner arc surface diameter is greater than self-locking liner plate inner arc surface diameter, and material can't form the material bed herein during work, has eliminated the generation of wedge chock wear phenomenon.
The invention has the beneficial effects as follows: through the design feature of self-locking liner plate self; Interfix radially realizing; Eliminated grinding machine when operation liner plate risk that comes off; Overcome in the traditional design in liner plate and cylinder inboard wall perforate the injury that the structural the subject of knowledge and the object of knowledge of apparatus body causes, improved the mill efficiency of equipment.
