Abstract
The utility model discloses splice type ball grinding machine lining board, it comprises liner plate (1) and lower liner plate (2), described upper liner plate and lower liner plate be affixed and keeping parallelism by trapezoidal connecting plate (3), described upper liner plate is provided with some circular protrusions (4) away from the side of trapezoidal connecting plate, described lower liner plate is provided with some circular protrusions away from the side of trapezoidal connecting plate, described trapezoidal connecting plate is provided with some circular protrusions, and the upper surface of described lower liner plate is provided with some arcs protuberance (5).The beneficial effects of the utility model liner plate are arranged to the combination of two blocks of liner plates and connecting plate, slitless connection is realized between liner plate and liner plate during such splicing, the intensity of liner plate is higher, before tight, when liner plate and the splicing of tight rear lining plate, the circular protrusions of upper liner plate and the circular protrusions of lower liner plate and connecting plate coordinate increasing friction force, and the arc protuberance of lower liner plate and the arc groove of upper liner plate coordinate increasing friction force.
Description
Technical field
The utility model relates to milling equipment, particularly relates to splice type ball grinding machine lining board.
Background technology
At present, ball mill is as pulverizer mill tool, be widely used in the industries such as power plant, cement, mine, refractory material, its basic functional principle is: ball mill barrel rotates with certain rotating speed, steel ball bottom ball mill barrel is subject to the effect of centrifugal force, frictional force, gravity, is attached on shell liner and moves with cylindrical shell.When steel ball is brought to certain altitude and after reaching disengaged position, parabolically rule falls, and carries out impact comminution and grinding to the material in cylindrical shell footing district.The liner plate of ball mill ensures ball mill critical component that is long-term, that steadily, normally run.As everyone knows, liner plate is all adopt bolt or dovetail to coordinate to add bolt mostly, due to the motion of tens tons of abrading-balls in ball mill, usually occur that liner plate ruptures, cause Lou powder, spillage, shut-down, contaminated environment,, often there is comparatively wide arc gap between liner plate and liner plate in the problem that maintenance load is large, easily allows boring passing through and do not have the effect of grinding in addition.
Utility model content
The technical problems to be solved in the utility model is that existing ball grinding machine lining board easily damages, and easily leaks material between liner plate and liner plate, provides a kind of splice type ball grinding machine lining board for this reason.
The technical solution of the utility model is: splice type ball grinding machine lining board, it comprises liner plate and lower liner plate, described upper liner plate and lower liner plate be affixed and keeping parallelism by trapezoidal connecting plate, described upper liner plate is provided with some circular protrusions away from the side of trapezoidal connecting plate, described lower liner plate is provided with some circular protrusions away from the side of trapezoidal connecting plate, described trapezoidal connecting plate is provided with some circular protrusions, and the upper surface of described lower liner plate is provided with some arcs protuberance.
The improvement of such scheme is that arc that the lower surface of described upper liner plate is provided with some and lower liner plate swells suitable arc groove.
The beneficial effects of the utility model liner plate are arranged to the combination of two blocks of liner plates and connecting plate, slitless connection is realized between liner plate and liner plate during such splicing, the intensity of liner plate is higher, before tight, when liner plate and the splicing of tight rear lining plate, the circular protrusions of upper liner plate and the circular protrusions of lower liner plate and connecting plate coordinate increasing friction force, and the arc protuberance of lower liner plate and the arc groove of upper liner plate coordinate increasing friction force.
Accompanying drawing explanation
Fig. 1 is the utility model schematic diagram;
In figure, 1, upper liner plate, 2, lower liner plate, 3, trapezoidal connecting plate, 4, circular protrusions, 5, arc protuberance.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further.
As shown in Figure 1, the utility model comprises liner plate 1 and lower liner plate 2, described upper liner plate and lower liner plate be affixed and keeping parallelism by trapezoidal connecting plate 3, described upper liner plate is provided with some circular protrusions away from the side of trapezoidal connecting plate, described lower liner plate is provided with some circular protrusions away from the side of trapezoidal connecting plate, described trapezoidal connecting plate is provided with some circular protrusions 4, and the upper surface of described lower liner plate is provided with some arcs protuberance 5.
During assembled liner plate, the upper liner plate of tight rear lining plate is adjacent to the connecting plate of tight front liner plate, circular protrusions on the upper liner plate of tight front liner plate is contacted with the circular protrusions of the connecting plate of tight front liner plate, strengthen frictional force and then strengthen adhesion, the connecting plate of tight rear lining plate contacts with the circular protrusions of the lower liner plate of tight front liner plate, further reinforcement adhesion, before tight, the arc protuberance of liner plate contacts with the upper surface of the lower liner plate of tight rear lining plate, again improves adhesion.
In order to strengthen in conjunction with effect further, can the upper surface of the lower liner plate of tight rear lining plate arrange some and tight before liner plate upper liner plate on arc protuberance coordinate arc groove, improve stiction, only need be adjacent between liner plate so between two can without the need to using the foreign objects such as screw, easy for installation, adhesion is strong, can not leak material from junction.
Claims (2)
