Abstract
The invention relates to an anti-skidding device for grinding table liners of a vertical mill. The anti-skidding device comprises a table body, the grinding table liners, pressing blocks and anti-skidding blocks, and is characterized in that the pressing blocks are wedge-shaped and matched with the wedge-shaped surfaces of the grinding table liners, and one plugging plate is crammed between every two grinding table liners; and notches are formed in the grinding table liners, and one anti-skidding block is installed between every two pressing blocks and inserted into the notch of each grinding table liner. According to the anti-skidding device, the firmness of the grinding table liners is improved, the phenomena of sliding detachment of the grinding table liners and even production halt, which are caused by large powder grinding force, are avoided, the effective running rate of the mill is improved to a large extent, and the maintenance cost is reduced greatly. Moreover, the anti-skidding device is simple and compact in structure, firm, reliable, practical, and convenient to produce and install.
Description
Technical field
The present invention relates to a kind of lining board for grinding discs shoe, particularly relate to a kind of grinding disc of vertical mill liner plate shoe.
Background technology
Mill is widely used in raw grinding, pulverized coal preparation, the production of the powder body material such as cement grinding and slag milling, its lining board for grinding discs long-term work is in mill, the pressure that is subject to grinding roller is very large, also will bear simultaneously larger material grinding power, this has just proposed very high requirement to lining board for grinding discs anti-skidding.Lining board for grinding discs causes very disadvantageous consequence in case slip is deviate to production.
The shoe that is used at present lining board for grinding discs both at home and abroad generally all is to adopt briquetting single anti-skidding, and perhaps latch is anti-skidding, and measure is more single.But in practice, only use briquetting, can't guarantee because the relative sliding that causes of gap between the liner plate, and long-term operation, wear liner strengthens, and can't realize that then liner plate fixes.Latch is anti-skidding then to have very high requirement, high expensive to installing and making.
Summary of the invention
The present invention provides a kind of grinding disc of vertical mill liner plate shoe for solving the technical problem that exists in the known technology, this device can prevent the relative sliding between the liner plate, has avoided lining board for grinding discs that whole sliding phenomenon occurs, and simple in structure, be convenient to install, manufacturing cost is lower.
The technical scheme that the present invention takes for the technical problem that exists in the solution known technology is: a kind of grinding disc of vertical mill liner plate shoe, by disk body, lining board for grinding discs, briquetting and non-slipping block combine, it is characterized in that described briquetting is the lozenges structure, cooperate with the lozenges of lining board for grinding discs, and fill between any two seben at lining board for grinding discs; Have breach on the described lining board for grinding discs, described non-slipping block is installed on briquetting between any two and inserts among the breach of lining board for grinding discs.
Advantage and good effect that the present invention has are: 1, briquetting is designed to the lozenges structure, cooperate with the lozenges of lining board for grinding discs, lining board for grinding discs is subject to and briquetting between the squeezing action of lozenges be fixed, the contact area of lozenges is larger, can guarantee thrust, simultaneously fill between any two corresponding seben at lining board for grinding discs, the jam-pack effect of the seben by different-thickness, and the material that produces behind the mill running fills, and can make between the lining board for grinding discs gap without relative sliding.2, offer breach at lining board for grinding discs, insert among the breach being installed on briquetting non-slipping block between any two, prevented that effectively the integral body of lining board for grinding discs from sliding.
In sum, the present invention has improved the fastness of lining board for grinding discs, has avoided because excessive grinding power causes lining board for grinding discs to slide, even has caused the phenomenon that stops production, has improved largely the effective running rate of grinding machine, greatly reduces maintenance cost.And the present invention is simple in structure, compact, solid and reliable, ease for use is strong, is convenient to make and install.
Description of drawings
Fig. 1 is structural representation of the present invention;
Fig. 2 is the A-A profile among Fig. 1;
Fig. 3 is the B-B profile among Fig. 1.
Among the figure: the 1st, lining board for grinding discs, the 2nd, non-slipping block, the 3rd, briquetting, the 4th, seben, the 5th, disk body, the 6th, bolt.
The specific embodiment
For further understanding summary of the invention of the present invention, Characteristic, hereby exemplify following examples, and cooperate accompanying drawing to be described in detail as follows:
See also Fig. 1, Fig. 2 and Fig. 3, a kind of grinding disc of vertical mill liner plate shoe, comprise disk body 5, lining board for grinding discs 1 and briquetting 3, described briquetting 3 is the lozenges structure, cooperate with the lozenges of lining board for grinding discs 1, and fill between any two seben 4 at lining board for grinding discs 1, and having breach at lining board for grinding discs 1, indentation, there is inserted with and is installed on briquetting 3 non-slipping block 2 between any two.
The erection sequence of said apparatus is as follows:
1, lining board for grinding discs 1 is positioned on the disk body 5;
2, be fixed in briquetting 3 on the lining board for grinding discs 1 and compress lining board for grinding discs 1;
3, non-slipping block 2 is installed on briquetting 3 between any two and insert among the breach of lining board for grinding discs 1, then be fixed on the disk body 5 with bolt 6;
4, at the seben of filling between any two respective thickness 4 of lining board for grinding discs 1 and guarantee that plug is real.
Operation principle of the present invention:
The grinding disc of vertical mill device in the running, the mill interior lining panel is to move under high grinding power state, be very easy to slide, the present invention is by the squeezing action of briquetting lozenges, the lifting surface area of guarantee effect power can more firmly be fixed lining board for grinding discs, has reduced the possibility that the lining board for grinding discs generation is slided.Utilize simultaneously the gap between the real lining board for grinding discs of seben plug, guaranteed relative sliding can not occur between the lining board for grinding discs.In addition, by the stopping function of non-slipping block, avoid lining board for grinding discs that whole sliding phenomenon occurs.The Integrated using of above-mentioned measure has played the anti-skidding effect to lining board for grinding discs, has avoided lining board for grinding discs to slide, and has guaranteed the normal operation of grinding machine.Not only improve effective running rate of grinding machine, also saved a considerable economic cost because keeping in repair and producing for the user.
Although the above is described the preferred embodiments of the present invention by reference to the accompanying drawings; but the present invention is not limited to the above-mentioned specific embodiment; the above-mentioned specific embodiment only is schematic; be not restrictive; those of ordinary skill in the art is under enlightenment of the present invention; not breaking away from the scope situation that aim of the present invention and claim protect, can also make a lot of forms, these all belong within protection scope of the present invention.
