Abstract
The utility model belongs to the ball grinding machine lining board technical field of structures, relate to a kind of arch bridge and give stress non-bolt bimetallic trench liner, be on the last lifting face of the hyperboloid working face (5) of plate body (1), to be equipped with a plurality of hyperboloid grooves (2), and previous go up on the lifting face the hyperboloid groove with back one on hyperboloid groove on the lifting face be staggered in opposite directions: be arranged with link slot (3) in the bottom of plate body both ends of the surface.The hyperboloid groove structure of the utility model design has not only strengthened the milling area of ball to material, and flour extraction is increased; And increased the lifting force of liner plate, reduced the consumption of the operation energy; Simultaneously, reduce the phenomenon that the abrading-ball sky is pounded liner plate, reduced noise.By being symmetrical arranged link slot in liner plate both ends of the surface bottom, with connector plate body is connected as one the whole circle of formation liner plate during assembling, the slight deformation of connector and liner plate produces and gives stress, makes the whole fastening reinforcement of liner plate of enclosing, and has eliminated leakage powder phenomenon.Plate body is a bimetal structure, has guaranteed that liner plate is in operation can not break to collapse, and the life-span of liner plate is increased substantially.
Description
Technical field
The utility model belongs to the ball grinding machine lining board technical field of structures, and what relate generally to is that a kind of arch bridge gives stress non-bolt bimetallic trench liner.
Background technology
In electric power, metallurgy, mine, building materials, chemical industry, refractories industry, adopted widely as the ball mill of milling equipment.Its ball grinding machine lining board profile working face is the hyperboloid structure because lining plate structure design is unreasonable, make liner plate occur the life-span short, noise is big, energy consumption is high, the problems of easy fracture, leakiness powder.As the mine liner plate, size is big mostly, Heavy Weight, not only gives and makes, installs and bring difficulty, also makes liner plate owing to exist casting flaw to be easy to fracture; Mine for another example, building material industry mostly has bolt hole with liner plate so that fix liner plate with bolt, though there is dovetail in thermal power plant with there not being screw on the liner plate, by with the dog wedge of bolting the liner plate jam-packed.These bolts are in operation and constantly are subjected to shear stress and action of pulling stress, thereby are easy to Broken bolt and leak powder, even cause liner plate to collapse; Because liner plate mostly is overall structure greatly, need satisfy better wearability and than the requirement of obdurability to the material of selecting, its working face has not only increased production cost, and has caused bigger waste in case promptly all scrap after the wearing and tearing.
Summary of the invention
The purpose of this utility model promptly produces thus, proposes a kind of arch bridge and gives stress non-bolt bimetallic trench liner.Make its not only integral body give stress reinforced, life-saving, cut down the consumption of energy, reduce noise, eliminated the Broken bolt problem, and be easy to install, alleviated maintenance load.
For achieving the above object, the technical scheme that utility model is taked is: be equipped with a plurality of hyperboloid grooves on the lifting face on the hyperboloid working face of plate body, and previous go up on the lifting face the hyperboloid groove with back one on hyperboloid groove on the lifting face be staggered in opposite directions; Bottom in the plate body both ends of the surface is arranged with link slot.
The described liner plate of utility model is the bimetallic composite construction.
The utility model is reasonable in design, and is simple in structure.It has not only strengthened the milling area of ball to material at the hyperboloid groove structure of working face design, makes flour extraction increase (generally can improve output 5～10%); And increased the lifting force of liner plate, and reduced the consumption of the operation energy, do not increasing under the investment condition, generally can economize on electricity 8～15 ‰; Simultaneously, reduce the phenomenon that the abrading-ball sky is pounded liner plate, generally can reduce 5～10 decibels of noises.Because its both ends of the surface bottom at liner plate is arranged with link slot, like this, when assembling, liner plate is connected as one with connector, this assembling is analogous to the domes of The Zhaozhou Bridge, the slight deformation of connector and liner plate produces gives stress, make the fastening reinforcement of whole circle liner plate, eliminated the leakage powder phenomenon of ball mill after running a period of time substantially, have characteristics easy for installation, as to alleviate maintenance load.Because liner plate is the bimetallic composite construction, working face is a 2 wear-resistant white cast, and non-working surface is good ZG31Mn2SiREB of toughness or carbon steel, metallurgical binding, thereby having guaranteed that the major diameter ball grinding machine lining board is in operation can not break collapses, and the life-span of liner plate is increased substantially.

Among the figure: 1, plate body, 2, the hyperboloid groove, 3, link slot, 4, connection strap, 5, working face, 6, non-working surface, 7, mounting bar.
The specific embodiment
In conjunction with the accompanying drawings, it is as follows to provide embodiment of the present utility model:
As shown in Figure 1: the liner plate that present embodiment proposes is wherein of the used liner plate of milling equipment ball mill, by plate body 1, groove 2 and link slot 3 constitute, the radially profiled outline of its working face 5 is asymmetric normal distribution curve, have two curved surfaces, on lifting face on each curved surface waveform, be equipped with row's hyperboloid groove 2, that every row has is a plurality of (4-8) hyperboloid groove 2, groove dimensions on the same waveform lifting face is identical, but the previous hyperboloid groove of going up on the lifting face 2 is staggered in opposite directions with a back hyperboloid groove 2 of going up on the lifting face.Hyperboloid groove 2 is special-shaped groove, and the opening degree of groove from top to bottom (direction of motion) dwindles gradually, and the degree of depth is 20～50mm, width 50～90mm, radian＞120 °.The both ends of the surface of plate body 1 are the plane, and the bottom is arranged with two link slots 3.For further improving the service life of liner plate, reduce production costs, plate body 1 can adopt the bimetallic composite construction, and working face 5 adopts 2 wear-resistant white cast, and non-working surface 6 adopts ZG31Mn2SiREB or carbon steel, metallurgical binding.During the present embodiment assembling, be connected to one by connection strap 4 and mounting bar 7.Mounting bar 7 adopts traditional structure, which is provided with screw, make by the ZG31Mn2SiREB abrasion-resistant stee that obdurability is good, its axial both ends of the surface are the inclined-plane, the intersection point on inclined-plane is the simplified axial line of ball mill, and both ends of the surface are the plane in addition, and the groove of two 50 * 20 * 20mm is arranged at the end bottom, the length of mounting bar is identical with liner plate, the about 100～150mm of its width.
