Description

Pressurization outer circulation flour mill is tiltedly put
(1) technical field:
The present invention relates to powder process equipment, specifically a kind of tiltedly pendulum pressurization outer circulation flour mill.
(2) background technology:
Flour mill is the widest equipment of breeze sector application, and wherein most representational equipment is raymond mill.
The universal architecture of raymond grinding powder machine host is:On main machine base equipped with hollow central shaft bracket and coaxial bull ring and Cover cylinder, main frame main shaft are stretched main frame main shaft upper end outside central shaft bracket and (or claim plum blossom equipped with fixed roll frame in the central shaft bracket Frame), there are grinding roller assembly that is multiple parallel with central shaft and being circumferentially distributed, grinding roller by the uniform hanging of hinge device on fixed roll frame Assembly is made up of grinding roller sleeve and grinding roller, and in the process of revolution of grinding roller assembly, grinding roller assembly makes each grinding roller by centrifugal action Keep between bull ring being in rolling contact, mutually rolling crushing material and reaching the mesh of production powder between grinding roller and bull ring , this is that the Cracking Mechanism of milling main frame is located.
The charging aperture of raymond mill is opened on cover cylinder, and the material entered from charging aperture substantially directly falls from bull ring Main machine base bottom is fallen within, material is rolled between grinding roller and bull ring mainly and relies on relieving tool post to drive perching knife rotation and complete, The perching knife throws material between the grinding roller being correspondingly arranged and bull ring.
As perching knife material casting angle is certain, and material is that light, heavy material movement locus is different from fine sand to block, Quite a few aniseed is idle to fly away, and causes feeding not enough, is that raymond mill yield in unit time is high, inefficiency weight Want reason.
(3) content of the invention:
For the deficiencies in the prior art, the technical problem to be solved is to propose one kind to lift working (machining) efficiency For the purpose of oblique pendulum pressurization outer circulation flour mill.
The oblique pendulum pressurization outer circulation flour mill of above-mentioned technical problem is can solve the problem that, including the main frame that is milled, the milling main frame Base endoporus bottom center installation center pedestal, the base endoporus top installs bull ring, base upper end mounting cup cylinder, Main frame material inlet is opened in the upper lid of cover cylinder, and main frame main shaft bottom is located in central shaft bracket and extends downwardly from base connection driver Structure, main frame main shaft upper end install fixed roll frame, are provided with Burnisher apparatus around main frame main shaft circumference uniform distribution, except that the grinding roller Device includes grinding roller sleeve, grinding roller and shaft of grinding roller, and the grinding roller sleeve by linkage, inwardly tiltedly hang on fixed roll frame by lower section, described Grinding roller is installed on shaft of grinding roller below grinding roller sleeve and leans to (the tiltedly side of hanging of grinding roller sleeve on the up big and down small taper grinding face of bull ring To oblique consistent with taper grinding face), the fixed roll frame is connected with bin is scraped, and described scrapes bin and central shaft bracket coaxial sleeve Dress, is provided with the equal charging tray for rotating coaxially above fixed roll frame;Main frame discharging opening is opened in base endoporus bottom by central shaft bracket, right Material scraping plate should be set in main frame discharging opening, the material scraping plate circumference uniform distribution is installed on to be scraped on bin, main frame discharging opening passes through pipeline The outer hierarchy system of connection machine;The outer hierarchy system of the machine includes grading, lifting machine, grader and cyclone separator, and the classification is carried The machine of liter and cyclone separator are respectively arranged on milling main frame both sides, and the grader is located above milling main frame, grading, lifting machine Charging aperture passes through pipeline connection main frame discharging opening, and the discharging opening of grading, lifting machine passes through the charging aperture of pipeline connection grader, institute The qualified products for stating grader enter cyclone separator by pipeline, and the substandard product of grader is flowed back by main frame material inlet Re-work in milling main frame.
The length of grinding roller sleeve can be set to identical, then the grinding roller in same tiltedly hang height and become individual layer roller; Or the length of grinding roller sleeve is set to difference, then the grinding roller tiltedly hangs height and becoming two-layer (is included with upper roller in different Two-layer roller).
The grinding roller sleeve is conventionally set to two kinds of length and forms the two-layer roller of upper and lower dislocation.
For improving grinding forces further, the fixed roll frame is provided with the boosting mechanism for acting on Burnisher apparatus, the reinforcing Mechanism includes boosting-rod, gusset, compression spring and hydraulic jack or cylinder, the hydraulic jack or cylinder located at fixed roll frame top Central authorities of portion, with being located on the piston rod that hydraulic jack or cylinder are protruded upward, the boosting-rod is corresponding to each for the gusset Grinding roller sleeve circumference uniform distribution is arranged, and the outer end of each boosting-rod is connected on the body above corresponding grinding roller sleeve hinge position, the pressure Contracting pressure mounting of the spring is balance pressure, sets on the gusset between the plate body of the inner of boosting-rod and gusset corresponding position There is the spring force governor motion for adjusting spring pressure size, the setting of the hydraulic jack or cylinder, is different in order to process Material and facilitate the regulation of grinding forces.
The circumferential edges of the equal charging tray are provided with rib, prevent material from tapping cover cylinder because centrifugal force throws away and produce noise.
Beneficial effects of the present invention:
1st, the present invention tiltedly puts pressurization outer circulation flour mill and separates finished product using machine outer circulation, and air exhauster energy loss is little, if Standby easy to maintenance.
2nd, shovel blade mechanism is not provided with present configuration, because nothing material casting action, reducing power consumption, be milled main frame Total-power loss is substantially reduced.
3rd, in present configuration, due to the material casting action produced without shovel blade mechanism, i.e., will not because of hard iron ore deposit, be scattered iron Block and there is card machine or ruin machine situation occur.
4th, in the present invention, when grinding roller quality, the radius of gyration, outstanding high, speed of gyration are constant, the grinding roller for leaning to is to material Grinding forces additionally can increase, and lean to the big then grinding forces of angle and increase;While material extends through taper grinding face drop-out time, favorably In milling.
5th, due to the effect of milling that has nature reinforcement and applied external force, the material high to Mohs' hardness more has the present invention Profit.
6th, the present invention sets up boosting mechanism, is to facilitate grinding forces to adjust to process different material.
7th, the equal charging tray outer rim of the present invention is provided with backgauge side, so that material is not produced and make an uproar because centrifugal force throws away percussion cover cylinder Sound, makes the material uniformly unrestrained area that mills, and it is more reasonable to distribute.
8th, present configuration is simple, low cost, manufacture handling ease, is the preferred unit of flour mill of new generation.
