Description
Technical field
The utility model belongs to the water-tight equipment of cement industry, relates in particular to raw material roller mill scraper plate cavity sealing device.
Background technique
The raw material roller mill of novel concrete dry process production line is in use with its technology advanced person, and safe and reliable to operation, less investment, the advantage that floor space is little, unit-hour output is high are extensively adopted by cement industry.But special because of the equipment operation operating mode, the defective of sealing transmission is the shortcoming of Vertical Mill environment and running.Because Vertical Mill is vertical installation, the process of standing by preparing burden belt is transported the material to grinding machine, enter Vertical Mill through three road air valves, be deposited in the middle of the mill, because the rotation of mill drives the grinding roller rotation, material moves to the mill edge under action of centrifugal force, mill between the engaging-in roller dish, between the roller dish only at the Reference diameter place, the linear velocity unanimity, all there is speed difference at other positions, promptly form and shear.In mill processes, there is partial material to be pushed to the edge, cross blocking material ring, taken up by high velocity air, the large particle mill that falls back carries out grinding again, granule is brought into separator, select powder under revolution fan blade effect, coarse granule is through the collision consumed energy mill that falls back, and qualified particle is sent into feed bin by the road by wind.Circulate up and down through tens times like this and can become finished product.Specific granule such as iron are fast etc., fall into the mill below through nozzle ring, are discharged outside the mill by scraper plate.
Because the hot blast of Vertical Mill is to enter from the bottom, discharge from the outlet on top through spout ring separator.So the material in the scraper plate chamber can leak outside along the gap of rotary packing ring, so the quality of Vertical Mill surrounding environment when producing depends on the sealing effect in scraper plate chamber.Because the bottom that is sealed in grinding machine in scraper plate chamber, and the used hot blast of grinding machine is again to enter from the bottom, goes into to grind hot blast at 200 ℃.Add that material washes away sealing and very easily be out of shape.Material enters the space between mill and the sealing awl in a large number, because abrasive disk seat is dynamic, the gap occurs when the stationary seal ring of bottom and the relative movement between the abrasive disk seat, causes a large amount of dust material excessive, seal ineffective gradually, environmental deterioration.
The model utility content
The purpose of this suction is to provide the seal arrangement in a kind of Vertical Mill transmission scraper plate chamber, and this device adapts to better tightness, by the multiple tracks raised seals, makes the dust material not enter cavity between abrasive disk seat and the static seal, to reach the purpose of sealing effect.
Be practical above-mentioned purpose, the utility model by the following technical solutions:
The seal arrangement in a kind of Vertical Mill transmission scraper plate chamber, comprise the sealing awl that is arranged on abrasive disk seat top, the seal ring and the sealing seat of abrasive disk seat bottom, sealing seat is installed on the grinding machine, sealing seat and sealing awl and seal ring constitute seal arrangement, top at sealing seat also is provided with static seal, be provided with motive sealing in sealing awl bottom, static seal and motive sealing constitute seal arrangement, and motive sealing can be rotated relative to static seal.
The seal arrangement in above-mentioned Vertical Mill transmission scraper plate chamber, described static seal is arranged on the stationary ring shape sealing plate on sealing seat top, be provided with two annular quiet projectioies that make progress at stationary ring shape sealing plate, be provided with running clearance between the annular quiet projection that two make progress, described motive sealing is arranged on the rotating ring shape sealing plate of sealing awl bottom, be provided with the moving projection of two downward annulars at rotating ring shape sealing plate, be provided with running clearance between two moving projectioies of downward annular, the moving projection of annular downward on the rotating ring shape sealing plate is stuck in two running clearances between the annular quiet projection that makes progress, and the moving projection of annular can be rotated in running clearance.
The seal arrangement in above-mentioned Vertical Mill transmission scraper plate chamber, described stationary ring shape sealing plate is welded on the top of sealing seat, and rotating ring shape sealing plate is welded on sealing awl bottom.
Adopt technique scheme, the utility model is by following advantage: stationary ring shape sealing plate is welded on the sealing awl, along with abrasive disk seat and sealing coning change, stationary ring shape sealing plate is welded on the former sealing seat static, utilizes gap between the sound and the projection on the sound annular seal plate to stop entering of material.From but granule dust is difficult for entering seal arrangement; also can stop in the first road projection even there is low amounts of dust to enter; be difficult to continue to enter by the second road raised seals dust; the utility model is transformed on the basis of original sealing; it is rational in infrastructure; non-maintaining; original seal arrangement is effectively protected; serviceability rate greatly improves; also can guarantee that dust granules can not enter even the local appearance of combination seal damages, use of the present utility model is greatly improved the vertical mill site environment; eliminate the secondary pollution phenomenon, improved operation rate.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
The seal arrangement in a kind of Vertical Mill transmission scraper plate chamber as shown in Figure 1, comprise the sealing awl 2 that is arranged on abrasive disk seat 1 top, the seal ring 3 of abrasive disk seat bottom and sealing seat 6, sealing seat 6 is installed on the grinding machine, sealing seat 6 and sealing awl 2 and seal ring 3 constitute seal arrangement, top at sealing seat 6 also is provided with static seal 4, be provided with motive sealing 5 in sealing awl bottom, static seal 4 and motive sealing 5 constitute seal arrangement, described static seal 4 is arranged on the stationary ring shape sealing plate 7 on sealing seat top, stationary ring shape sealing plate be provided with two make progress annular quiet protruding 8, two make progress annular quiet protruding 8 between be provided with running clearance, described motive sealing 5 is arranged on the rotating ring shape sealing plate 9 of sealing awl bottom, rotating ring shape sealing plate 9 is provided with the moving projection 10 of two downward annulars, be provided with running clearance between two moving projectioies 10 of downward annular, on the rotating ring shape sealing plate the moving projection 10 of downward annular be stuck in two make progress annular quiet protruding 8 between running clearance in, and the moving projection 10 of annular can be rotated in running clearance, described stationary ring shape sealing plate 7 is welded on the top of sealing seat 6, and rotating ring shape sealing plate 9 is welded on sealing awl 2 bottoms.
