Abstract

The utility model relates to a high-efficiency vertical combined grinder for coal, which is suitable for a crushing and milling combined processing apparatus used for the coal used in the cement machine vertical kiln production or other industries and the corresponding materials. The coarse grinding and the fine grinding operation of the material can be completed in one time, and the reduction ratio can reach 300. The utility model has the advantages of low cost, low energy consumption, high crushing efficiency, light weight, etc.

Description

High-efficiency vertical combined grinder for coal
The utility model is to belong to coal and the fragmentation of corresponding material and the process equipment of grinding combination that a kind of manufacture of cement or other industry are used.
The milling equipment of existing coal is as small grinder, vertical Raymond mill, chain hammer type disintegrating machine etc., because in small, broken bits failing separately in these equipment, coal dust grinds meticulously, is used for cement in vertical kiln production just seem cost height, energy consumption height, output and inefficient phenomenon.
The purpose of this utility model is the special-purpose milling equipment of a cement equipment shaft kiln production usefulness of design, specific tasks are to realize cement slurry and coal grinding respectively, are convenient to quality of pc control, also are convenient to the grain composition of choose reasonable coal, to satisfy the burning process requirement, help the machine shaft kiln and close door operation.
Technical conceive of the present utility model is according to the thick broken and combined method of fine grinding of the crushing performance employing of material, and material is once finished to fine powder by coarse grain.
The feature of technical solutions of the utility model is:
(1) complete machine top is disintegrating apparatus, and the bottom is a muller equipment, the airtight vertical transmission of double motor;
(2) airtight top disintegrating apparatus has last main shaft, and spreading disk is equipped with on last main shaft top, and which floor hinge hammer last main shaft stage casing adorns, last main shaft bottom refills down spreading disk, airtight perisporium is welded with the waveform liner plate, and 5～30 millimeters gaps are arranged between waveform liner plate and the tup, and gap form adopts from big to small;
(3) airtight bottom muller equipment, the top is the taper stock guide, and it covers gentle breeze blade, mill disc, muller and the sawtooth scraper plate that is contained on the lower main axis, and the top disintegrating apparatus connects mutually through taper stock guide outer perimeter;
(4) adopt the labyrinth seal that is added with grease between muller and the muller axle.
The advantageous combination of advantage collection chain of the present utility model hammer disintegrating machine and Raymond mill, be used in have in the cement equipment shaft kiln production that cost is low, energy consumption is low, in light weight, characteristics that crush efficiency is high, material is once finished to fine grinding by meal, the ratio of reduction can reach 300.
The technical solution of the utility model Fig. 1 in conjunction with the embodiments is illustrated:
Go up main shaft 1 drive chain 3 and tup 4 among Fig. 1 with rotation at a high speed, when material joins the certain speed of acquisition on the spreading disk 2, at this moment tup 4 bumps with chain 3 and material, material is smashed, make the material high-speed impact material is broken once more to the waveform liner plate 6 simultaneously, and clash into mutually between the high-speed motion material, increased crushing effect.Close gap when material hits on waveform liner plate 6 stalled glide between tup 4 and the waveform liner plate 6 is pushed material, increases crushing effect again.Broken purpose during material has reached through the top disintegrating apparatus.
In material after broken slide into the edge of mill disc 10 again by spreading disk 5 and taper stock guide 13 down.Lower main axis 11 drives muller 8 rotations and produces the huge downward inertia force and the moment of momentum, between muller 8 and mill disc 10, produce huge extruding force like this, sawtooth scraper plate 12 is to play a part stirring, supplies along the mill disc downslide, making the effect of milling more abundant.
In order not make dust from flying, gentle breeze blade 7 has been installed in its structure specially, reduced the dust in grinding machine space, bottom.Because muller work media is a coal dust; for making muller energy operate as normal; adopt labyrinth seal 9 between muller and the muller axle; add grease in the maze trough, when muller turns round, under action of centrifugal force; grease is pressed in the maze trough; make dust be difficult for entering muller inside, thereby played the effect of protection bearing, guarantee the muller operate as normal.
Last material is scraped into discharging opening 14 under the effect of sawtooth scraper plate.

Claims (1)

1, a kind of high-efficiency vertical combination coal mill is characterized in that:
(1) complete machine top is disintegrating apparatus, and the bottom is a muller equipment, the airtight vertical transmission of double motor;
(2) airtight top disintegrating apparatus has last main shaft 1, spreading disk 2 is equipped with on last main shaft 1 top, which floor hinge hammer 3 and 4 last main shaft stage casing adorns, last main shaft bottom refills down spreading disk 5, the sealing perisporium is welded with waveform liner plate 6,5～30 millimeters gaps are arranged between waveform liner plate 6 and the tup 4, and gap form adopts from big to small;
(3) airtight bottom muller equipment, the top is a taper stock guide 14, it covers the gentle breeze blade 7 that is contained on the lower main axis 11, mill disc 10, muller 8 and sawtooth scraper plate 12, the top disintegrating apparatus connects mutually through taper stock guide 14 outer perimeter;
(4) muller and and the muller axle between adopt the labyrinth seal 9 be added with grease.
