Description
(1) technical field:
The present invention relates to powder process equipment, is a kind of tiltedly pendulum waterfall material flour mill specifically.
(2) background technology:
Flour mill is breeze sector application equipment the most widely, and wherein the representational equipment of most is raymond mill.
The universal architecture of raymond grinding powder machine host is: main machine base is equipped with hollow central shaft bracket and coaxial bull ring and cover cylinder, main frame main shaft is located in central shaft bracket, fixed roll frame (or claiming plum blossom frame) is equipped with in the main frame main shaft upper end of stretching outside central shaft bracket, fixed roll frame there is multiple and grinding roller assembly of circumferentially distributing parallel with central shaft by the even hanging of hinge device, grinding roller assembly is made up of grinding roller sleeve and grinding roller, in the process of revolution of grinding roller assembly, grinding roller assembly makes to keep Structure deformation between each grinding roller and bull ring by centrifugal action, crushing material to be reached the object of producing powder by mutually rolling between grinding roller and bull ring, this is the Cracking Mechanism place of abrasive dust main frame.
The charging aperture of raymond mill is opened on cover cylinder, the material entered from charging aperture is directly fall bottom main machine base from bull ring substantially, material rolls and mainly relies on relieving tool post drive perching knife rotate and complete between grinding roller and bull ring, and material is thrown between the grinding roller and bull ring of corresponding setting by described perching knife.
Because perching knife material casting angle is certain, and material is from fine sand to 4 centimetres of blocks not etc., light, heavy material movement locus is different, and quite a few aniseed is idle to fly away, and causes feeding not enough, is that raymond mill yield in unit time is not high, the major reason of inefficiency.
(3) summary of the invention:
For this reason, the present invention proposes a kind of tiltedly pendulum waterfall material flour mill, mainly solve the problem that traditional raymond mill working (machining) efficiency is low.
The oblique pendulum waterfall material flour mill that can solve the problem, comprise abrasive dust main frame, the base bottom mounting center pedestal of abrasive dust main frame, base top endoporus installs bull ring, base upper end mounting cup cylinder, main frame main shaft bottom to be located in central shaft bracket and to be stretched out connection for transmission mechanism downwards, main frame main shaft top coaxial package relieving tool post, the fixed roll frame be connected with relieving tool post top is equipped with in main frame main shaft upper end, bottom relieving tool post, perching knife is installed, longitudinal-pendulum type Burnisher apparatus is provided with around main frame main shaft circumference uniform distribution, described Burnisher apparatus comprises grinding roller sleeve unlike the prior art, grinding roller and shaft of grinding roller, described grinding roller sleeve inwardly tiltedly hangs on fixed roll frame in below by linkage, described grinding roller is installed on shaft of grinding roller and leans on the up big and down small taper grinding face of bull ring below grinding roller sleeve, grinding roller sleeve tiltedly hang the oblique consistent of direction and taper flour milling, described cover cylinder is in base upper end outer rim and the base upper end in cover cylinder and bull ring upper end surface area is surrounded buildup district (described buildup district is more many greatly than routine), described cover cylinder is offered more than one charging aperture, arrange the material that the enters spiral deflector chute to the uniform distribution of buildup district on described cover cylinder corresponding to charging aperture.
In said structure, material is piled up prior to buildup district, along with material is cumulative and the vibrations of abrasive dust main frame in work, material can along the landing as the waterfall of taper flour milling, mill material bed at the self-assembling formation between district of milling of grinding roller and bull ring, formation is forced to be milled material bed (perching knife is thrown the material flown and fallen buildup district) along with the continuous feed of perching knife, the increase of district's inventory of milling and material bed thickening, for raising output and efficiency have established solid foundation; And taper flour milling adds area of milling, the weight fraction masterpiece of grinding roller adds grinding forces on bull ring, and output and efficiency are further enhanced.
Can be set to identical by the length of grinding roller sleeve, then described grinding roller is in same tiltedly hanging highly and becomes individual layer roller; Or the length of described grinding roller sleeve is set to difference, then grinding roller is in different tiltedly hanging height and become two-layer with top roll (comprising two-layer roller).
Conventionally grinding roller sleeve be set to two kinds of length and form the two-layer roller of upper and lower dislocation.
For improving grinding forces further, be provided with thrust mechanism grinding roller sleeve being produced to thrust between described grinding roller sleeve and relieving tool post, the active force of described thrust mechanism is perpendicular to the axis of grinding roller sleeve.
Described thrust mechanism is elastic body or for hydraulic mechanism or for air pressure mechanism, or be the combining structure of elastic body and hydraulic mechanism or be the combining structure of elastic body and air pressure mechanism.
For making the returning charge after classification be gathered in buildup district, arranging coaxial inner core, form the ring cavity of charging and classification returning charge between cover cylinder and inner core in described cover cylinder, the graded region corresponding to cover cylinder suitable for reading of described ring cavity, the end opening of described ring cavity corresponds to buildup district.
Beneficial effect of the present invention:
1, the present invention tiltedly puts waterfall material flour mill and arranges buildup district and adopt waterfall cutting mode, forms two supply and to mill material, realize the Homogeneous charge to the district that mills in conjunction with perching knife feed.
2, the present invention is due to can Homogeneous charge, eliminates the unnecessary consume of empty mill mutually between grinding roller and bull ring.
3, in the present invention, when grinding roller quality, the radius of gyration, outstanding high, speed of gyration are constant, the grinding roller leaned to can additionally increase the grinding forces of material, leans to the large then grinding forces of angle and increases; Material extends through taper grinding face drop-out time simultaneously, is conducive to milling.
4, the present invention is owing to there being the effect of milling of nature reinforcement, and the material high to Mohs' hardness is more favourable.
5, structure of the present invention is simple, cost is low, manufacture handling ease, is the preferred unit of flour mill of new generation.
