Technical Field
The utility model relates to a steel ball mill in a power plant, in particular to a detachable energy-saving lining plate.
Background
The ball mill is the main grinding equipment used in the industries of mine, cement, electric power, chemical industry and the like, so far, the lining plate of the ball mill mainly uses metal, rubber is adopted under the working conditions of part two and three sections, and the consumption of the metal lining plate in the whole country is about 60 ten thousand tons according to statistics, wherein the main metal raw material is iron which is a limited resource owned by human beings, particularly in China, the iron ore is barren, the exploitation cost is high, and the environmental pollution is serious.
The operation of the mill is carried out in a mill cylinder body, and a steel ball and a milled medium are filled in the cylinder body. After the steel ball and the medium are brought to a certain height along with the rotation of the cylinder, the steel ball and the medium fall down due to the dead weight of the steel ball and the medium. On the other hand, because the medium revolves and rotates in the cylinder along the axis of the cylinder, mutual impact, extrusion and grinding force are generated between the medium and the contact area between the medium and the cylinder, so that the medium is ground.
The existing lining plate of the ball mill has the following defects:
1. the wave-shaped structure of the original lining plate can not effectively improve the parabolic height of the steel ball, and the steel ball runs along the wave curve of the lining plate when the cylinder body moves, so that the crushing rate of coal is reduced.
2. Although the whole structure of the lining plate is a wave curve, only points or points connecting lines are in contact in the relative motion of the steel ball and the lining plate, so the relative output of the original lining plate structure is insufficient.
3. After the liner was used, we examined to find: the most worn portion of the liner is the weakest portion of the liner (the valley portion of the liner), and the wave crests have enough thickness to cause material waste.
SUMMERY OF THE UTILITY MODEL
In view of the above problems, the present invention is directed to a detachable energy saving lining board.
In order to realize the technical purpose, the scheme of the utility model is as follows:

The specific meaning of the above terms in the present invention can be understood by those of ordinary skill in the art through specific situations.
The utility model is described in further detail below with reference to the figures and specific embodiments.
As shown in the figure, the specific embodiment of the utility model is
The utility model provides a can dismantle energy-conserving welt, includes wear-resisting bottom plate 1, wear-resisting bottom plate on be provided with through-hole 11, its characterized in that: the through hole 11 is connected with a detachable surface-adjusting ball-lifting rib plate 2 through a bolt 3, the center of the detachable surface-adjusting ball-lifting rib plate is transversely provided with a step 21, and the center of the step 21 is transversely provided with a groove 22.
Preferably, the steps 21 and the grooves 22 have the same length.
Preferably, the step 21 is provided with a chamfer.
Preferably, the left and right sides of the groove 22 are inclined outwards.
When embodied in practice
Because friction force exists between the steel ball of the ball mill and the cylinder body, when the cylinder body rotates, the steel ball is taken up and lifted to a certain height, and finally falls along a certain track under the action of the gravity of the steel ball. The steel ball in the area (where it is carried) is subjected to two forces: one is the acting force applied to the steel ball from the tangent line direction when the cylinder rotates, and the other is the force opposite to the acting force on the surface symmetrical to the diameter of the steel ball, and the acting force is generated due to the downward sliding of the steel ball due to the self weight of the steel ball. Therefore, the above two forces constitute a couple for any one steel ball. And because the steel balls are extruded between the cylinder and the adjacent steel balls, force couples can cause the steel balls to have frictional resistance with different sizes, so that each layer of steel balls can do revolution motion along with the axis of the cylinder (certainly, each layer of steel balls does not have synchronous speed with the cylinder, and the revolution speed of each layer of steel balls is different). The steel ball falls from above in the region and is thrown off, so that a strong impact-breaking action occurs in the region on the medium in the cylinder. The steel ball produces an extremely intense and disorganized motion in the region due to the impact force produced when the ball falls.
From the above point of view, the increase of energy consumption of the mill has the influence of structural defects of the lining plate and improper steel ball-grade ratio, and also has the reasons of poor medium grindability, medium quantitative supply, wind pressure and wind speed and the like.
The utility model breaks the wave-shaped structure, adopts the structure form of detachable steps (bolt connection), can effectively improve the height of the ball, ensures the parabolic motion of the steel ball in the cylinder and fully exerts the crushing capacity of the steel ball;
the liner plate bottom plate adopts a groove structure, the steel balls and the liner plate are in line-to-line contact in the relative movement, the crushing capacity of the steel balls on coal is effectively improved, and the productivity is improved;
the lining plate structure of the utility model has the combination of steps and grooves, which divides the functions of the steel ball into crushing and grinding, thereby reducing unnecessary material waste of the lining plate.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and any minor modifications, equivalent replacements and improvements made to the above embodiment according to the technical spirit of the present invention should be included in the protection scope of the technical solution of the present invention.
