Abstract
The invention relates to cement building material machinery equipment, in particular to a large-scale vertical mill with combined mill disc, which comprises a machine frame, a mill disc device arranged in the machine frame and an air channel system, wherein a central shell and a mill roller pressurizing system are arranged above the machine frame; a separator is arranged above the central shell; the inside of the central shell is provided with a feeding system and provided with a power-driven system. The large-scale vertical mill with combined mill disc is characterized in that the upper and lower half parts of the mill discs in the mill disc device are connected through a flange and a bolt. The large-scale vertical mill with combined mill disc solves the problems that the volume of the mill disc in the prior large scale vertical mill is large, heavy, and difficult to manufacture, process and transport, particularly a speed reducer is damaged directly once the mill disc is cracked anddamaged. The large-scale vertical mill is mainly suitable to be used in raw materials, coal dust, cement and furnace slag powder milling systems in cement production.
Description
(1) technical field:
The present invention relates to the cement building material plant equipment, is a kind of large-scale vertical mill with combined mill disc.
(2) background technology:
Vertical mill is with its output height, mill efficiency height, low power consumption and other advantages, and instead of ball mill gradually becomes the preferred unit of raw material and cement grinding system in the manufacture of cement.
Vertical barreling system technology started from the beginning of last century, begin progressively to develop to China's Vertical Mill development eighties technology, so far Vertical Mill development technology has all developed comparatively ripe both at home and abroad, the existing vertical mill manufacturer of many families provides the vertical mill of various types to the client, wherein famous Loesche mill as Loesche (Lai Xie company), the ATOX mill of FLS (Smith company), the MPS mill of Pfeiffer (Pu Feifo company), this mill of uncle's power turtledove of Polysius company, the CKP of Kawasaki, Japan heavy industry mill etc., there is Shenyang Heavy Machinery Plant in domestic present vertical mill supplier, in letter Heavy Machinery Plant etc.
Though vertical mill form has multiple, but its operation principle and basic structure are much the same, mainly include frame, be contained in mill device and ducting system in the frame, central enclosure and grinding roller compression system are equipped with in the frame top, separator is equipped with in the top of central enclosure, is provided with feed system in central enclosure, and is furnished with power-driven system.We find to exist following problem by the reality investigation for existing vertical mill:
1. the most of mill device of domestic and international all kinds of Vertical Mill is all done global design, and large-scale Vertical Mill is existed that the mill device volume is big, weight big, the casting difficulty of processing is big, is not easy to problem such as transportation, the large scale development of grinding machine is formed restrict.
2. the monoblock type mill is at the scene in the use, (grinding roller add compression and tension) influence because mill structure and actual loading, simultaneously because casting flaw very easily produces the vertical crackle that extends from upper surface downwards, and the monoblock type mill is directly to contact with the output flange and the planet carrier of grinding machine main gear reducer on mounting structure, in use in a single day mill cracks when damaging, and will cause coup injury to reductor simultaneously.
(3) summary of the invention:
Purpose of the present invention be exactly to solve that mill volume in the existing large-scale vertical mill is big, weight big, make processing, the transportation difficulty, in a single day mill cracks damage, can directly cause the problem of damage to main gear reducer, and a kind of large-scale vertical mill with combined mill disc is provided.
Specific design scheme of the present invention is: improve at existing large-scale vertical mill, this vertical mill includes frame, be contained in mill device and ducting system in the frame, central enclosure and grinding roller compression system are equipped with in the frame top, separator is equipped with in the top of central enclosure, is provided with feed system in central enclosure, and is furnished with power-driven system, it is characterized in that: the mill in the described mill device is to adopt flange arrangement by upper and lower two halves, and forms by Bolt Connection.
Two halves butt joint location is reliable up and down in order to guarantee mill, and the upper and lower two halves interface of mill described in the present invention adopts fixing structure and the spacing butt joint of neat key of joint.Certainly can also adopt other location structures such as alignment pin spacing.
The present invention is simple in structure, directly effectively, its mill split modular structure, it is self-evident greatly facilitating processing and transportation, particularly fabricated structure about it has solved effectively and after in a single day mill cracks main gear reducer has been brought the problem of damage.Because mill generally is the grinding roller pressurized operation because of upper surface, influenced by tension force, easily from the upper end cracking, for the monoblock type mill, in case the upper end cracking, will the whole cracking of very fast generation.And for combined polishing disc up and down of the present invention, the upper end is in case cracking only can exert an influence to the first half, and the Lower Half influence is little, thereby has protected main gear reducer effectively.Can keep in repair by changing first half mill on the other hand, avoid whole mill to scrap, reach the purpose of saving material and reducing maintenance cost.
(4) description of drawings:
Fig. 1 is a general structure schematic diagram of the present invention;
Fig. 2 is a general structure left view of the present invention;
Fig. 3 is the mill master cutaway view among the present invention.
Among the figure: 1-frame, 2-mill device, 3-ducting system, 4-grinding roller compression system, 5-central enclosure, 6-separator, 7-feed system, 8-power-driven system, the last disk body of 9-, 10-bolt, 11-seam, disk body under the 12-, the neat key of joint of 13-.
(5) specific embodiment:
Referring to Fig. 1, Fig. 2, the present invention has the basic structure of common vertical mill, it includes frame 1, be contained in mill device 2 and ducting system 3 in the frame 1, central enclosure 5 and grinding roller compression system 4 are equipped with in frame 1 top, separator 6 is equipped with in the top of central enclosure 5, in central enclosure 5, be provided with feed system 7, and is furnished with power-driven system 8, particularly the mill among the present invention has changed combined type up and down into by monoblock type, its concrete structure is referring to Fig. 3, and this mill is by last disk body 9 and following disk body 12 employing flange arrangements, by bolt 10 composition that fuses.For making up and down disk body 9 and 12 butt joints accurately and reliably, the disk body up and down 9 of mill and 12 interface adopt seam 11 location butt joints outward among the present invention.Promptly have a circle groove, and be shaped on the boss that a circle and groove match in the lower port inside edge of last disk body 9, and adopt neat key of joint 13 to do circumferentially to locate at the joint sidewall of disk body 9 up and down and 12 in the following upper port inside edge of disk body 12.Certainly up and down disk body can also adopt the butt joint of alternate manner location, as alignment pin etc.
Claims (2)
1. large-scale vertical mill with combined mill disc, it includes frame, be contained in mill device and ducting system in the frame, central enclosure and grinding roller compression system are equipped with in the frame top, separator is equipped with in the top of central enclosure, is provided with feed system in central enclosure, and is furnished with power-driven system, it is characterized in that: the mill in the described mill device is to adopt flange arrangement by upper and lower two halves, and forms by Bolt Connection.
