Description
Technical field
This patent belongs to cement industry milling equipment technical field, particularly relates to water injector in a kind of vertical roller grinder mill.
Background technology
Vertical Mill is to be widely used at present cement, electric power, a kind of energy-conservation milling equipment of the industries such as iron and steel.For guaranteeing that Vertical Mill can run well, controlling the Vertical Mill vibration is a very important link.As everyone knows, in mill, the water spray main purpose is to stablize thickness of feed layer on mill, and keeps controlled injection flow rate also to be conducive to according to actual condition Stabilizing Materials layer thickness, and then guarantees mill output.When the grinding machine bed of material fluctuates when large, will certainly cause the grinding machine current fluctuation to reach greatly grinding machine vibration even stop jumping bigger than normal, if when lining board for grinding discs and grinding roller roller shell may wear to the later stage, the fluctuation of the grinding machine bed of material not only can cause the grinding machine current fluctuation greatly even to exceed the quata to determine the electric current stop jumping, and can make the collision probability of grinding roller and lining board for grinding discs increase and damage liner plate.
At present, the mode of stablizing the grinding machine bed of material is by spraying water in Vertical Mill, makes the material increasing friction force in mill, thereby guarantees that material forms the more uniform bed of material of thickness on mill, reduces the grinding machine vibration.In production practices, because common Water spraying device for vertical mill injection flow rate is uncontrollable, spray water inhomogeneous, can cause the grinding machine thickness of feed layer inhomogeneous, while making grinding roller load because storeroom frictional force is little, easily material is pressed loose, easily produce directly impact between grinding roller and mill, thereby cause the high vibration of grinding machine, affect the normal operation of equipment.In addition, because sparge pipe is easy to wear, hole for water spraying is easily stifled, and the easy like this sparge pipe that causes is worn out, local a large amount of flowing water or piles up obstruction due to hole for water spraying and can not spray water under the high density dust atmosphere.
Therefore, how Water spraying device for vertical mill can be sprayed at appropriate water equably on the material bed under the high density dust atmosphere, guarantee that material forms the stable bed of material on mill, thus simultaneously and hole for water spraying easy to wear at sparge pipe easily how quick-replaceable does not affect under stifled actual condition produces the problem that the running rate that guarantees Vertical Mill just becomes the urgent need solution.
Summary of the invention
This patent provides water injector in a kind of vertical roller grinder mill for solving the technical problem existed in known technology.
This device can work under the high density dust atmosphere, realizes that in mill, injection flow rate is controlled, water spray is even, is difficult for producing and stops up; Be easy to change after water pipe wearing and tearing, guarantee that material forms the stable bed of material on mill, reach and reduce the grinding machine vibration and guarantee the Vertical Mill normal operation.
The technical scheme that this patent is taked for the technical problem existed in the solution known technology is:
Water injector in the vertical roller grinder mill, comprise independently horizontal water-supply-pipe and the interior flanged horizontal sparge pipe of mill in system water spray power unit, the outer horizontal annular water-supply-pipe of mill, mill, also comprise the connection vertical tube that is arranged on each grinding roller Nodes, the outer horizontal annular water-supply-pipe of described mill is communicated with horizontal water-supply-pipe in mill by the connection vertical tube of each grinding roller Nodes, and in described mill, horizontal water-supply-pipe is communicated with flanged horizontal sparge pipe in the mill radially extended in its lower direction mill.
This patent can also adopt following technical scheme:
In described connection vertical tube, mill, horizontal water-supply-pipe is identical with the internal diameter of flanged horizontal sparge pipe in mill.
In described mill, flanged horizontal sparge pipe length is identical with the width of grinding roller.
In described mill, the length of horizontal water-supply-pipe can guarantee that in mill, flanged horizontal sparge pipe is near the bed of material of mill, and in mill, the locus of horizontal water-supply-pipe is positioned at the top of ejection high velocity air vane.
In described mill, horizontal water-supply-pipe outside is provided with and is convenient to the wear-resistant protection cover of changing.
Advantage and good effect that this patent has are: because this patent adopts technique scheme, the outer horizontal annular water-supply-pipe of mill upwards is communicated with horizontal water-supply-pipe in mill by each grinding roller Nodes connection vertical tube, by the flanged horizontal sparge pipe radially extended in the interior horizontal water-supply-pipe of mill and its lower direction mill, is connected; This water injector is furnished with independently system water spray power unit, and this unit provides flow and the controlled water spray (injection flow rate is generally 0-8t/h, and hydraulic pressure is generally 0.3-0.6Mpa) of pressure after filtering by the action of inner valve group and each instrument motor in mill.Water in system water spray power unit enters the outer horizontal annular water-supply-pipe of mill by connecting line, be communicated with horizontal water-supply-pipe in mill through the Vertical Mill middle shell via vertical tube connector at each grinding roller Nodes, be sprayed at equably on the mill bed of material in last flanged horizontal sparge pipe below its end enters.So neither increase the installation cost, can also reduce to greatest extent field apparatus the workload of adjusting is installed; Independently system is sprayed water, and the power unit principle is simple, telotism.This patent is simple in structure, reasonable in design, can effectively on the grinding machine bed of material, spray water equably; In mill, under the high density dust atmosphere, work, injection flow rate is controlled, water spray is even, spray orifice is difficult for stopping up, the vulnerable part fast changeable, guaranteed that well material forms the stable bed of material on mill, thereby reduced grinding machine, vibrated the normal operation of guaranteeing the Vertical Mill long-term stability.
