Abstract
The utility model relates to a vertical mill, and in particular relates to a vertical mill abrasive water injection device. A water inlet pipe is fixed above an annular water pipe in a sealing manner, a plurality of water outlet pipes are uniformly fixed below the annular water pipe in a sealing manner, and the tail end of each water outlet pipe is fixed with a nozzle. The vertical mill abrasive water injection device has a simple structure, and the vibration of the vertical mill during the operation process can be obviously reduced.
Description
Technical field
The utility model relates to a kind of vertical mill, particularly vertical mill abrasive material water injector.
Background technology
Vertical mill adopts a material bed grinding principle grinding abrasive material, has the mill efficiency height, power consumption is low, drying capacity is big, it is big into the mill abrasive grain to allow, advantages such as grinding process is simple, floor space is little, civil engineering costs is low, noise is low, wearing and tearing are little, the life-span is long, processing ease.In recent years, the development of vertical mill rapidly, in industries such as cement, iron and steel by wide popularization and application.
Because the abrasive material that gets into vertical mill is through after rolling repeatedly, the abrasive material between mill and the grinding roller is pulverulence, and dry abrasive powder can't form a stable backing strap between mill and grinding roller, thereby causes vertical mill vibration to increase.In order to alleviate the vibration that vertical mill produces in the running, thickness is even, the bed of material of intensity stabilization is a key factor.Through spraying water on the bed of material in vertical mill, make powdery abrasive material temporary bonding by the surface tension of hydrone, thereby guarantee to form between mill and the grinding roller thickness evenly, the backing strap of intensity stabilization, reduce the vibration of vertical mill.The device that present vertical mill adds water only on the mill a bit perhaps what time carrying out single-point adds water, the water mode that adds of single-point exists and adds shortcomings such as water is inhomogeneous, water consumption is excessive.Add that water is inhomogeneous directly to have caused the inhomogeneous of backing strap, cause that the vibration of vertical mill increases, vertical mill itself, motor, equipment losses such as reductor aggravate.
Summary of the invention
In order to overcome the shortcoming of prior art, the utility model provides a kind of vertical mill abrasive material water injector, and it is simple in structure, can obviously reduce the vibration in the vertical mill operation process.
The technical scheme that its technical problem of the utility model solution is taked is: the water pipe top sealing and fixing water inlet pipe of annular, a plurality of outlet pipes, the terminal stationary nozzle of each outlet pipe are evenly fixed in the below sealing.
It is more even that the utility model adds water, and owing to water spray was accomplished before abrasive material gets into mill, abrasive material has adequate time to absorb moisture, so when abrasive material entering grinding roller rolls, can produce the stable backing strap of thickness, obviously reduces the vibration in the vertical mill operation process.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the utility model front view;
Fig. 2 is the utility model upward view;
Fig. 3 is the practical state reference map of the utility model.
The specific embodiment
Like Fig. 1, shown in 2, annular conduit 3 top sealing and fixing water inlet pipes 1, the evenly fixing a plurality of outlet pipes 2 of below sealing, the terminal stationary nozzle 4 of each outlet pipe 2.
The annular internal diameter of said annular conduit 3 is bigger slightly than the external diameter of vertical mill blanking tube 5.
As shown in Figure 3, the utility model is fixed on the blanking tube 5 of vertical mill.
Claims (2)
