Description

Pressurization self-balancing super large roller flour mill
Technical field
This utility model relates to ring roll mill or Raymond mill, especially relates to a kind of pressurization self-balancing super large roller flour mill.
Background technology
The most conventional flour mill includes suspension mill (or referred to as Raymond mill) and ring roll mill (or referred to as three rings mill).The main frame of overhang roll mill constructs as shown in Figure 1, including support 1-1, the bull ring 1-2 being arranged on support 1-1, and it is arranged on the interior rolling device with grinding roller 1-3 of main frame, the working shaft 1-4 rotation being positioned at host center position drives the grinding roller 1-3 of rolling device to press to bull ring, rolls the material being between bull ring 1-2 and grinding roller 1-3.From figure 1 it appears that the diameter of the grinding roller 1-3 on rolling device is due to the setting of central task axle 1-4, causes its size can not exceed the 1/2 of bull ring diameter, therefore limit total output and the grinding efficiency of flour mill.
The main frame of ring roll flour mill constructs as in figure 2 it is shown, include support 2-1, and the bull ring 2-2 being arranged on support is provided with three layers of (or more layers) grinding roller 2-4 on the rotor 2-3 being arranged in bull ring.Multilamellar grinding roller 2-4 empty set is on the axle 2-5 driving its revolution.When center rotor 2-3 rotates, empty set grinding roller 2-4 on axle 2-5 revolves round the sun around the centre of gyration, and under the influence of centrifugal force, grinding roller 2-4 can be thrown toward on deep bull ring 2-2, thus rolls the material between bull ring and grinding roller.The ring roll mill simple in construction of this traditional structure, grinding roller is placed on axle, and not having parts of bearings, shortcoming is that grinding roller diameter is little, grinding pressure is little, and engaging-in material is few, yields poorly, efficiency is low, and empty set grinding roller on axle, due to friction, impact etc., can produce huge noise in actual production.
Must being fulfilled for basic constraints during grinding machine work: condition one is that by the trackability of grinding roller parts during material change, condition two is each parts operationally centrifugal force balance.Because conventional mill bull ring is static, abrasive body barycenter must do revolution and could realize moving along rolling of bull ring, it is impossible for requiring that abrasive body does not the most produce centrifugal force, and centrifugal force is also the crushing force of conventional mill, so conventional mill arranges two or more grinding roller parts and realizes mutually balancing becoming necessarily.
Summary of the invention
The purpose of this utility model is to provide a kind of pressurization self-balancing super large roller flour mill, and during the work of this flour mill, grinding roller barycenter does not revolves round the sun, and material is engaging-in many, and work efficiency is high, and yield is high.
For achieving the above object, this utility model can take following technical proposals:
Pressurization self-balancing super large roller flour mill described in the utility model, including support and be arranged on the bull ring on described support, grinding roller parts it are provided with in described bull ring, described grinding roller parts are by being arranged on the center rotor driving work of support center position, described grinding roller parts are set with by interior grinding roller and outer grinding roller and form, and are provided with rolling bearing between described interior grinding roller and the faying face of outer grinding roller;The level on the center rotor of described grinding roller centre bore that is positioned at offers axis hole, the gyroaxis two ends being located in described axis hole extend to described interior grinding roller sidewall, and on the center rotor being positioned at described gyroaxis upper and lower position, the symmetrical staggered blind hole offered is respectively arranged with grinding roller thrust device.
Described center rotor is made up of fixed jacket and fork disposed within, 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 grinding roller centre bore, the gyroaxis two ends being located in described axis hole extend to described interior grinding roller sidewall, and on the fork being positioned at described gyroaxis upper and lower position, the symmetrical staggered blind hole offered is respectively arranged with grinding roller thrust device.
Described interior grinding roller thrust device is push action cylinder/cylinder or thrust spring.
Described rolling bearing is sliding bearing or rolling bearing.
Offer lubricating oil on the support corresponding with described rolling bearing position and collect runner.
At described outer grinding roller top, seal buckle is provided with protective cover.
The utility model has the advantage of that structure is ingenious, reasonable, break away from grinding roller of wheat flour-milling parts and can not be made the design limit of exceed bull ring diameter 1/2, the diameter of grinding roller parts can be close to the size of bull ring internal diameter in theory, for comparing traditional structure, the grinding roller parts of super large structure can make material engaging-in many, efficiency is high, and yield is high;The barycenter of the grinding roller parts of point symmetry design simultaneously is located at turn around on axle, and during work, the barycenter of grinding roller parts does not revolves round the sun, and centrifugal force is zero, even if changing at material thickness, when needing grinding roller servo-actuated, this state remains to keep;Thrust device promotes grinding roller parts to swing and presses to bull ring, its thrust is main crushing force, when overcoming centrifugal force from principle as main broken power, crushing force relies on (both become quadratic relationship) to the height of rotating speed, make crushing force, rotating speed, material by the important parameter such as evacuation time when rolling can be the most independent reach optimum state, can better adapt to grind the various materials that coefficient is different.
