Description

The four-wheel mica grinds

Technical field

The utility model belongs to mill machinery, and a kind of four-wheel mica that is specifically related to process natural mica (or other material of similar mica character for example graphite) grinds.

Background technology

Mica powder is a kind of new additive agent, is used for industries such as paint, rubber, plastics, cosmetics more; Range of application enlarges day by day in recent years.But the mica powder difficulty of processing is very big, because mica powder not only requires to have granularity, and requires to become " fine powder " of sheet, radius-thickness ratio (ratio of diameter and thickness) require be: 1: 40,1: 60,1: 80 or thinner; " fine powder " of this specification requirement, common disintegrating apparatus can't be pulverized.

A kind of edge runner that reaches specification requirement like this is abroad arranged, but complex structure, the cost height, bulk strength and power are all bigger; For example, its mill disc is provided with large-scale plane thrust bearing with grinding the seat place, and complex structure is installed difficulty, and the cost extra-high-speed; It can be used for multiple material pulverizing is not the special use of special tailored powder garrulous mica.

Domestic someone once attempts the edge runner with two-wheeled, grinds as mica and uses; But result on trial is undesirable, wants the radius-thickness ratio that reaches minimum, and the cycle is long, yield poorly; When requiring to reach radius-thickness ratio in the time of 1: 50, output is lower, does not have industrial value.

The utility model content

Goal of the invention of the present utility model, be design be fit to the current national conditions of China a kind of four-wheel mica grind.Its technical scheme is: design a kind of four-wheel mica and grind, comprise the stone roller seat, be arranged on the mill disc and muller, driving mechanism, clearance adjustment mechanism and the discharging mechanism that grind on the seat, it is characterized in that:

Grind the seat top counterweight is set; The muller of two groups of symmetries co-operating is set with one heart around a vertical axis on the mill disc; Muller connects with a driving mechanism, and mill disc connects with another driving mechanism; Between mill disc and stone roller seat the sliding bearing formula is set and supports, the muller axle is provided with clearance adjustment mechanism; Grind the seat periphery discharging mechanism is set.

The counterweight that its above-mentioned stone roller seat top is provided with, its quality is greater than the quality of grinding seat; Its above-mentioned sliding bearing formula supports and comprises the annular projection that the mill disc lower surface is provided with and grind the annular recess that the seat upper surface is provided with, both positions, the corresponding coupling of shape; The sidewall of annular recess communicates with the lubricant level meter; Its above-mentioned muller axle is provided with the gap adjustment component, comprises by symmetrically arranged adjustment bolt on location-plate that is provided with in the muller crosshead and the location-plate constituting; On the location-plate of the muller crosshead that it is above-mentioned, scraper plate is set; The discharging mechanism that its above-mentioned stone roller seat periphery is provided with is by grinding seat peripheral annular receiving vat, the discharge nozzle that the ring-type receiving vat is laterally disposed; The mill disc lower surface is provided with the position of ring-type receiving vat, the scraper plate of form fit and the discharge opening that has movable drain plug of mill disc periphery setting and constitutes.

The utility model has the advantages that:

1. architectural feature has determined it to be fit to very much make the special equipment that mica powder is pulverized, and can reach the specification requirement that mica is pulverized easily;

2. volume is little, in light weight, low in energy consumption and inexpensive, and during identical output, power consumption only is 2/3 of an external similar devices, and cost only is 1/20 of an external similar devices.

The specific embodiment

Among the figure, the motor 5 in the driving mechanism drives 1 concentric, the co-operating of two groups of mullers by link gear, and muller 1 turns clockwise together with scraper plate 19; Mill disc 2 is driven (not drawing among the figure) by the motor in another driving mechanism by link gear and is rotated counterclockwise; Rely on reverse frustrating between the two to grind, mica powder is processed.In order to reduce the iron-holder in the mica powder, mill disc 2 adopts the stainless steel Welding Structure; Mill disc 2 is on-stream will to bear very big axial force, and the mill disc plane does not allow end face run-out.We adopt the sliding bearing formula to support to it, promptly in mill disc 2 lower surfaces annular projection 8 are set, and grind seat 3 upper surfaces annular recess 9 is set, both positions, the corresponding coupling of shape; The sidewall of annular recess 9 communicates with lubricant level meter 6 through control valve, pipeline, guarantees that annular projection 8 in service is in good lubricating status with annular recess 9; So structural-load-carrying capacity is big, and manufacturing cost is far below rolling plane bearing or more complicated large-scale plane thrust bearing.

2 of muller 1 and mills disc must have rational gap, otherwise, mica powder can not be ground into the sheet particulate, this gap also should be adjustable, we are provided with location-plate 13 at crosshead 11 places of muller 1 at test, be symmetrical arranged on the location-plate 13 and adjust bolt 12, the end of adjusting bolt 12 withstands on muller 1 crank throw 10 places; Because behind this gap adjustment location, no cause specific need not be changed substantially, be feasible therefore by regulating manually.

Grind the seat periphery and ring-type receiving vat 18 is set, ring-type receiving vat 18 laterally disposed discharge nozzles 19; Mill disc 2 lower surfaces are provided with position, the scraper plate 14 of form fit and the discharge opening 17 that mill disc 2 peripheries are provided with movable drain plug 16 with the ring-type receiving vat, constitute discharging mechanism.When discharging, manually pull up movable drain plug 16, discharge opening 17 connects, and grinds the rotation of mica powder well along with mill disc 2, drops on equably in the receiving vat 18; Be fixed with several piece scraper plate 14 in the lower surface of mill disc 2,,, send via discharge nozzle 19 with the powder that drops in the receiving vat 18 along with the rotation of mill disc 2.

Owing to grind the seat top counterweight 4 is set, the quality of counterweight 4 can be supported by column 7 and column 15 etc. so grind seat 3 greater than the quality of grinding seat 3, and the basis is firm, runs well.

On probation through putting into practice, the utility model is simple in structure, and dependable performance is easy to make, keep in repair, and cost is low, is the comparatively desirable mica powder process equipment that is fit to China's national situation.
