Description
Technical field
The present invention relates to ring roller mill or Raymond mill, especially relate to a kind of pressurization super big roller pulverizing mill of self-equilibrating.
Background technology
Pulverizing mill conventional at present comprises suspension mill (or being referred to as Raymond mill) and ring roller mill (or being referred to as three ring mills). The main frame of overhang roll mill constructs as shown in Figure 1, comprise support 1-1, the bull ring 1-2 being arranged on support 1-1, and the rolling device being arranged in main frame with mill roller 1-3, the working shaft 1-4 rotation being positioned at host center position drives the mill roller 1-3 of rolling device to press to bull ring, is rolled by the material being between bull ring 1-2 and mill roller 1-3. As can be seen from Figure 1, the diameter of the mill roller 1-3 on rolling device, due to the setting of central task axle 1-4, causes its size can not exceed the 1/2 of bull ring diameter, because which limit ultimate production and the mill efficiency of pulverizing mill.
The main frame of ring roller pulverizing mill constructs as shown in Figure 2, comprises support 2-1, the bull ring 2-2 being arranged on support, is arranged on the rotor 2-3 in bull ring to be provided with three layers (or more layer) and grinds roller 2-4. Multilayer mill roller 2-4 empty set is on the axle 2-5 driving its revolution. When center rotor 2-3 rotates, the mill roller 2-4 of empty set on axle 2-5 revolves round the sun around center of turning circle, and under the influence of centrifugal force, mill roller 2-4 can be thrown toward on the bull ring 2-2 away from center, thus rolls the material between bull ring and mill roller. The ring roller mill structure of this kind of traditional structure is simple, and mill roller is placed on axle, it does not have bearing parts, and shortcoming is that mill roller diameter is little, grinding pressure is little, nibbles into material few, and output is low, efficiency is low, and the mill roller of empty set on axle, due to friction, impact etc., can produce huge noise in actual production.
Grinding machine must meet basic constraint condition when working: condition one is the trackability that can realize mill roller member when material changes, and condition two is each parts operationally centrifugal force balances. Because conventional mill bull ring is static, grinding element barycenter must do revolution and could realize moving along rolling of bull ring, it is impossible for requiring that grinding element does not externally produce centrifugal force, and centrifugal force is also the crushing force of conventional mill, so conventional mill arranges the two or more mill mutual balance of roller member realization becomes inevitable.
Summary of the invention
It is an object of the invention to provide a kind of pressurization super big roller pulverizing mill of self-equilibrating, when this pulverizing mill works, mill roller barycenter does not revolve round the sun, and material is nibbled many, working efficiency height, output height.
For achieving the above object, the present invention can take following technical proposals:
The super big roller pulverizing mill of pressurization self-equilibrating of the present invention, the bull ring comprising support and be arranged on described support, mill roller member it is provided with in described bull ring, described mill roller member is by being arranged on the center rotor driving work of support center position, described mill roller member is filled with outer grinding roller sleeve by interior mill roller, is provided with rolling bearing between described interior mill roller and the bonding surface of outer mill roller; Being positioned on the center rotor of described mill roller centre hole level has offered axis hole, the rotating shaft two ends being located in described axis hole extend to described interior mill roller sidewall, and on the center rotor being positioned at described rotating shaft upper and lower position, the symmetrical staggered blind hole offered is respectively arranged with mill roller thrust device.
Described center rotor is by fixed jacket and puts fork in the inner and forms, described fork is connected by hinge with the lower end of fixed jacket, described axis hole is opened on the fork extended in described interior mill roller centre hole, the rotating shaft two ends being located in described axis hole extend to described interior mill roller sidewall, and on the fork being positioned at described rotating shaft upper and lower position, the symmetrical staggered blind hole offered is respectively arranged with mill roller thrust device.
Described interior mill roller thrust device is push action cylinder/cylinder or thrust spring.
Described rolling bearing is sliding surface bearing or rolling bearing.
Lubricant oil collection runner offered by the support corresponding with described rolling bearing position.
It is provided with shield cap at described outer mill roller top seal button.
It is an advantage of the current invention that structure is ingenious, reasonable, broken away from grinding roller of wheat flour-milling parts can not do exceed bull ring diameter 1/2 design limit, the diameter grinding roller member in theory can close to the size of bull ring internal diameter, compare traditional structure, it is many that the mill roller member of super macrostructure can make material nibble, efficiency height, output height; The barycenter of the mill roller member of point symmetry design simultaneously is positioned on rotating shaft, and the barycenter grinding roller member during work does not revolve round the sun, and centrifugal force is zero, even if changing at material thickness, it is necessary to when mill roller is servo-actuated, this kind of state still can keep; Thrust device promotes mill roller member to swing and presses to bull ring, its thrust is main crushing force, when overcoming centrifugal force principle as main broken power, the height of rotating speed is relied on (both become quadratic relationship) by crushing force, make crushing force, rotating speed, material independent separately can reach optimum regime by important parameters such as exhaust times when rolling, can adapt to better to grind the different various materials of coefficient.
