Abstract
The utility model relates to ball mill lining board, particularly a coupling self-locking alloy magnesium iron ball mill lining board, which uses alloy magnesium iron material which has the advantages of good toughness, work-hardening capacity (HRC can be increased by 20% in the process of working), and no macroscopic deformation. The utility model comprises a barrel lining board and a rivet panel and is combined by the barrel lining board, the rivet panel, and a prestress block through the coupling self-locking without screw bolts. Because prestress is stressed on the barrel lining board during installation and the direct shock between a grinding ball and materials causes the pivot panel to be deformed to rivet the barrel lining board tightly and continually, the utility model has the advantages of simple and convenient installation, long service life, no leakage of powder and pulp, and on-line maintenance in service life.
Description
The utility model relates to a kind of coupling self-locking ball grinding machine lining board, especially a kind of coupling self-locking shellfish alloy ductile iron difficult to understand ball grinding machine lining board.
Widely used ball grinding machine lining board in industries such as cement, electric power, mine, chemical industry; generally there are two kinds the locking mode is installed: a kind of for all having bolt hole on the liner plate; the need manpower screws a hundreds of nut during installation, installation workload is big; and impact, the vibrations owing to abrading-ball and material easily cause bolt looseness, fracture in the running; the lighter causes Lou powder spillage; contaminated environment, weight person causes the frequent shutdown maintenance, influences unit-hour output.In addition, owing on the liner plate bolt hole is arranged, this is the source of liner plate fracture often, increases maintenance, the replacing workload of liner plate.Another kind is to pass through the dovetail interconnection between the liner plate, locks by pressing plate at last during installation.This liner plate is applied to last the concentrating of all stress on the follower bolt in running, causes follower bolt to bear tension for a long time.Very easily cause bolt looseness, cause the screw place to leak powder, spillage, last fatigue fracture causes stopping accident.
The purpose of this utility model is to provide at above-mentioned the deficiencies in the prior art to grow and do not leak the coupling self-locking ball grinding machine lining board of powder, spillage, on-line maintenance a kind of service life in service life.
The technical solution of the utility model is a kind of coupling self-locking ball grinding machine lining board, comprise cylindrical shell lining body and riveting plate, its key is to be provided with the shell liner group, and every group of shell liner is made up of some shell liners, be provided with the riveting plate between the adjacent shell liner group, the riveting plate is installed on the ball mill barrel; Also be provided with the prestressing force piece, the prestressing force piece is located between the shell liner in the shell liner group, the ball grinding machine lining board back side and the ball mill barrel contact-making surface that are formed by shell liner, riveting plate, prestressing force piece are the cambered surface that adapts, shell liner, riveting plate, prestressing force piece side are the inclined-plane, and two match in abutting connection with the inclined-plane.
Above-mentioned riveting plate is provided with bolt hole, and the riveting plate is installed on the ball mill barrel by bolt.
Can be provided with 1～3 prestressing force piece in the above-mentioned shell liner group.
Two boss also can respectively be established in the both sides of described shell liner, and the two boss inclined-planes in abutting connection with boss inclined-plane or adjacency match and contact with riveting plate inclined-plane/prestressing force piece inclined-plane.
Above-mentioned shell liner is preferably selected shellfish alloy ductile iron liner plate difficult to understand for use, and the riveting plate can be cast with mild steel, and the prestressing force piece is welded by general steel plate, and the prestressing force piece is knocked in and is located between the shell liner from two shell liner sides.
And the back side of shell liner has negative area.
When the utility model is installed, earlier the riveting plate is fastened on the ball mill barrel, puts into shell liner successively, apply and be bumped into the prestressing force piece behind certain prestressing force and get final product.Whole process is safe and reliable, last bolt, need not use support when screwing bolt.The utility model adopts that each inclined-plane matches, the self-locking structure of shell liner non-bolt and apply prestressing force by knocking in the prestressing force piece; and the bolt on the riveting plate only plays fastening and positioning action; install the back bolt and no longer bear tension; thereby long service life of the present utility model; and in service life, do not leak the powder spillage; on-line maintenance is installed simple and convenient.
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a shell liner schematic diagram of the present utility model.
Fig. 3 is the A-A view of Fig. 2.
Referring to Fig. 1～Fig. 3, the utility model comprises shell liner 4 and riveting plate 2, by several cylindrical shells.Be provided with riveting plate 2 between liner plate 4 formation shell liner groups 11, the adjacent shell liner group 11, riveting plate 2 is installed on the ball mill barrel 1, as connecting firmly mode by establishing bolt hole 6 on the riveting plate 2 and being fixed on the cylindrical shell 1 or with other by bolt 7, the utility model also is provided with prestressing force piece 5, prestressing force piece 5 is located between the shell liner 4 in the shell liner group 11, knock in from two liner plate 4 sides, one circle liner plate is applied prestressing force, and this prestressing force piece 5 is the key links that guarantee the safe operation in early stage of non-bolt liner plate.The ball grinding machine lining board back side 3 that is formed by shell liner 4, riveting plate 2, prestressing force piece 5 is the cambered surface that adapts with ball mill barrel 1 contact-making surface, closely contacts to guarantee both.Shell liner 4, riveting plate 2 and prestressing force piece 5 sides 8,10,9 are the inclined-plane, and two match in abutting connection with the inclined-plane.
The number of prestressing force piece 5 can be set as required, generally establishes 1～3 prestressing force piece 5 in each shell liner group 11.
Stability is installed for increasing, can with the two sides of shell liner 4 respectively symmetric design go out two boss 12, boss 12 sides 8 are the inclined-plane, the two boss inclined-planes 8 in abutting connection with boss inclined-plane 8 or adjacency match with 10/ prestressing force piece inclined-plane 9, riveting plate inclined-plane and contact.
Shell liner 4 of the present utility model is recommended with shellfish alloy ductile iron liner plate difficult to understand, this liner plate combines material hardness and toughness together well, thereby can alleviate blastic deformation wearing and tearing and abrasive material cutting abrasion in the use, can resist powerful abrading-ball and material impulsive force again, particularly this material liner plate under arms in the process austenite reach 15～20% because of work hardening reinforcing material case hardness, can guarantee that liner plate neither breaks and enough wearabilities are arranged, and the liner plate of this material advantage in use not having macroscopic deformation, grow up, be convenient to install maintenance.Riveting plate 2 is cast by mild steel, and its two sides 10 directly contact with the boss side surfaces 8 of shell liner 4 respectively, in the running because the direct impact of abrading-ball and material, the liner plate of constantly riveting tightly.Prestressing force piece 5 is welded by general steel plate.
In addition, in order to reduce liner plate weight and to save material, the back side of shell liner also can be provided with several negative areas 13.
