Abstract
The invention provides a shell structure of a grinding roller of a roll mill. The shell structure of the grinding roller of the roll mill comprises a shell body, wherein end socket mounting openings are formed in the left side and the right side of the shell body; an end socket of the grinding roller is mounted on each end socket mounting opening; a pressure shaft mounting part is fixedly mounted at the bottom of the end socket of the grinding roller; end socket fixing parts protrude the outer sides of the end sockets of the grinding roller; thread through holes are formed in the end socket fixing parts; thread holes are screwed at the corresponding positions of protruding parts on the other sides of the opening parts of the end socket mounting openings in the left side and the right side of the shell body; and the end sockets of the grinding roller pass through the thread through holes in the end socket fixing parts through bolts, and lock the thread holes in protruding parts on the other sides of the opening parts of the end socket mounting openings. According to the shell structure of the grinding roller of the roll mill, provided by the invention, the shell of the roll mill is in a split structure, so that the anti-vibration function of the entire shell is improved; noises generated in the working process of the roll mill are reduced; and the strength of the shell is improved. Meanwhile, the mill has a good sealing property in the process of milling inflammable and explosive substances, such as coal powder, so that the anti-pressure function and the anti-explosion function can be improved. The entire shell structure is simple, and is convenient to maintain, mount and dismount.
Description
Technical field
The present invention relates to the material grinding equipment, specifically just relate to the ring-roller mill of milling for various materials of industry such as metallic ore, nonmetallic ore, the energy, new materials, especially a kind of structure that can strengthen the ring-roller mill housing seal.
Background technology
Along with the economical activities of mankind development, food and clothing is lived row four aspects as the base substance condition of human survival, is accompanied by the development of scientific and technological level, also obtained further raising, it is full that people not only will eat aspect eating, and that also will eat is good, the health of eating; The basic demand of taking shelter from rain from keeping out the wind in the aspect of living, becoming requires firm, the safety and comfort of living; Wear the clothes be also more and more pursue colourful, pass each people's personality, and the main progress of row is embodied on the vehicles, people are from original walking by pin, develop into bicycle, automobile afterwards, aircraft, people even till now take the spaceship tourism, have all embodied the progress of scientific and technological level to the improvement of people's life.
especially the aspect of living, basically there is in life time of about 1/3rd to spend in sleep due to people, so people extremely value living conditions, nest and occupy from the ancient times people, developing into the cave lives in concentrated communities, and banda extremely afterwards, the sun-dried mud brick room, and the various cement works in modern age, the more next moon of people's living environment is comfortable, simultaneously, needs due to natural calamities such as opposing earthquake hurricanes, the firm security performance of building requires also more and more higher, so adopt the construction material of energy antidetonation for example to become the first-selection that the mankind build the building residential house in the house of cement construction, and cement generally all will pass through the grinding machine technique that raw material is levigate, the degree that raw material is levigate has very dark impact to the quality of cement, and the levigate degree of raw material is decided by that the selection of grinding machine develops into the modern times, usually select ring-roller mill to carry out levigate to raw material in the levigate process of cement production process.
Ring-roller mill also claims vertical grinder, medium speed mill, be the milling equipment that integrates in small, broken bits, oven dry, grinding, selects powder, carries, be widely used in grinding and the ultrafine grinding grinding of the various solid materials of the industries such as cement, building materials, electric power, metallurgy, chemical industry, nonmetallic ore.Ring-roller mill has the history in century more than one so far from invention, and the grinding process of ring-roller mill is completed by a cover milling device (being grinding roller and mill), and material is milled into powdery between grinding roller and mill.The motion of milling device is milled pressure except the grinding roller deadweight by mill revolution and the transmission of corresponding drive grinding roller, mainly by a cover hydraulic means, the mill material is pressurizeed.There are a large amount of meal in material after milling, select powder through supporting powder concentrator, the powder process of selecting of powder is through pneumatic separation, most of meal is fallen on mill automatically in the air current flow process, receive grinding again, all the other are selected through powder concentrator and are finished product, through gathering dust and induction system is sent into the finished product bank.
traditional ring-roller mill closed performance is relatively poor, because grinding machine work is that hard particles is levigate, when causing existing traditional ring-roller mill work, noise is larger, affect working environment, Chinese patent application numbers 201120174551.1 discloses a kind of vertical mill, comprise the mill body with charging aperture and discharging opening, be located at the mill in mill body, drive the transmission mechanism that mill rotates, be located at grinding roller and the separator that is located at the mill top on mill, the mill body bottom is provided with air inlet, the characteristics of this vertical mill maximum are simple in structure, noise is little, energy consumption is lower, but in fact this vertical mill just changes over vertical mill with ball mill, can not thoroughly solve the large defective of grinding machine noise, and the general commutativity of this vertical mill is not strong, maintenance is inconvenient, and this vertical mill sealing is not strong, easily leak out, leak ash.
Chinese patent application numbers 200510031126.6 discloses a kind of vertical mill, and it comprises charging aperture, discharging opening, grinding roller, mill, device for exerting, grinding roller, abrasive disk space adjusting device, floating bearing, bearing spider, deceleration device, support.Support is installed on the ground; Bearing spider is arranged on support or is directly installed on ground; Mill is contained on bearing spider by floating bearing, the output of deceleration device, be connected with the turning circle of floating bearing by flange, gear or other drive disk assembly, described deceleration device can be mechanical reduction gear, belt reduction unit or their combination, can be arranged on bearing spider, on support or be directly installed on the bottom surface.This vertical mill is simple in structure, but can find out from disclosed technical data, whole vertical shell is an integral structure from being fed to discharging, maintenance and sealing property are relatively poor, complexity is installed, when vertical mill is for combustibles such as coal-grindings simultaneously, high-level anti-pressure, capability of antidetonance requirement is arranged, in case when the closure of ring-roller mill is strong, coal dusts etc. have the danger of blast when still particle mixes with air, explosion-proof, the anti-pressure property of the vertical mill that this patent provides all can't be satisfied the demand fully.
Summary of the invention
Structure for the housing of existing ring-roller mill grinding roller installation position is all a monolithic construction, resistance to compression is explosion-proof, the ability of antidetonation noise abatement is relatively poor, the shortcoming of complex structure maintenance and installation inconvenience, the invention provides the shell structure of a kind of ring-roller mill grinding roller installation position, can make up easily and install, be convenient to maintenance, total intensity improves greatly, greatly improve resistance to compression, explosion-proof, anti-vibration ability, reduced the insecurity of impact and the production of NOISE ON ENVIRONMENT.
