Abstract
The utility model discloses a turning material discharging device for mechanical vertical kiln which is a discharging grate inlaid by a fluted disc, a hemisphere disk and crushing teeth. A filter is formed by the upper inclined plane of the fluted disc and the tangential direction of the hemisphere disk, a skewed-tooth-shaped movable jaw plate is arranged on the inclined plane of the circumference on the fluted disc. Ventilation holes are arranged on the discharging grate which is parallel to the axial direction of the vertical kiln, the ventilation holes are as 35-45 per cent area as the discharging grate. Compared with the original tower-typed grate, the utility model has the advantages that the steel products are saved, the service life is long, the effect of the centralized ventilation of the vertical kiln is good, the production and quality of cement is increased.
Description
The utility model is the transformation that is used for the cement mechanized shaft kiln device for discharging.
The discharging double-edged fine-toothed comb of existing tower mechanical vertical kiln, what have is monoblock cast, what have is the layering combination, the unloading tooth of these discharging double-edged fine-toothed combs, i.e. wearing and tearing in about about a year, behind the odontotripsis, the discharging double-edged fine-toothed comb is wanted integral replacing, causes maintenance time long, and steel consumption is many.Because the restriction of tower body shape, air vent and the center line of kiln on it of distributing is difficult for parallel, increased flowing resistance, reduced the ventilation effect in the middle part of the shaft kiln.
The purpose of this utility model is to enlarge the draught area of discharging double-edged fine-toothed comb, improves the ventilation condition in shaft kiln centre, and reduces the maintenance time and the steel consumption of discharging double-edged fine-toothed comb, prolongs its service life.
The hemisphere dish can inserted revolution discharger, it is discharging double-edged fine-toothed comb by fluted disc, hemisphere dish and crushing teeth edge system, the transition that is oriented in a tangential direction of the ramp of fluted disc and hemisphere dish, the movable Jaw plate of helical teeth shape is housed on all prisms in fluted disc garden, be parallel to the shaft kiln axis direction on the discharging double-edged fine-toothed comb and be furnished with air vent, the discharging double-edged fine-toothed comb is assembled on the transmission main shaft, and main shaft drive double-edged fine-toothed comb turns round finishes the discharging function.
Be illustrated in conjunction with the accompanying drawings now, the discharging double-edged fine-toothed comb is made up of fluted disc (1), hemispherical fluted disc (2) and crushing teeth (3), the transition that is oriented in a tangential direction of the ramp of fluted disc (1) and hemisphere dish.Established law is to being inlaid with 18～24 crushing teeths on hemisphere face, and this hemisphere face is the some of spherical, is about the sphere of radius 1/3.On fluted disc (1), inlay 24～36 crushing teeths, all replaceable behind these odontotripsises.Profile of tooth is 100 * 100 * 320 millimeters square taper.Make with the 45# forged steel, the surface is through Wear-resistant Treatment.Fluted disc and hemisphere dish are 45# cast steel and make, and thickness is the 60-100 millimeter.
On the discharging double-edged fine-toothed comb, be parallel to the shaft kiln axis direction and arrange air vent, the irregular between cog that is distributed in of air vent, hole shape can become rectangle, crooked rectangle (on the fluted disc) or triangle with the between cog shape.The full-size in hole is 120 millimeters, for preventing to get stuck hole shape is made up-small and down-big form.The area of air vent is the 35-45% of discharging double-edged fine-toothed comb area, improves 20-30% than existing tower machine shaft kiln.
On all prisms in fluted disc garden, be assembled with the movable Jaw plate (4) of helical teeth shape, movable Jaw plate can be fixed on the fluted disc with two screws, change after being convenient to wear and tear, the impact endurance test shock that produces when reducing discharging reduces power consumption, makes stable drive, therefore movable Jaw plate is made between helical teeth shape it and the quiet Jaw plate (5) and formed crusher chamber, in order to discharge.
The advantage of this device for discharging because crushing teeth system of can inlaying and movable Jaw plate are convenient to replacing, can be saved steel 1.5-3 ton than each replacement cycle of original step grate.Can reach the service life of discharging double-edged fine-toothed comb more than 10 years, draught area increases by 20% than former step grate, the ventilation effect in shaft kiln centre obviously improves, compare with the tower machine shaft kiln of same specification, output can improve 10-20%, free lime is reduced to below 2% by 2.5%, and the grog label can improve 60MPa.
Embodiment: Huangxian county, Yantai City, Shandong Province is all by the cement plant, can inserted revolution discharger on the machine shaft kiln of 2.66 * 10 meters of φ with the hemisphere dish, crushing teeth is 60, draught area is 45% of a discharging double-edged fine-toothed comb area, and crushing teeth only changed 2 times till now from 85 years, fluted disc wearing and tearing 12-13 millimeter, the grog free lime is below 2%, cement grade is brought up to the 525#R type by 425#, and product all exports, and average unit-hour output is brought up to 11.4 tons by 8.5 tons.
