Abstract
The utility model provides an internal water spraying device of a vertical roller mill. The internal water spraying device of the vertical roller mill is composed of a spray pipe, a pouring water bin, and a V-shaped stack solder, wherein a flange plate connected with the vertical roller mill is arranged at one end of the spray pipe; the other end of the spray pipe is sealed; a blow hole is formed below the spray pipe; the V-shaped stack solder is arranged above the spray pipe; an inversely-triangular pouring material bin is arranged in the middle of the spray pipe; and a castable is fully filled inside the pouring material bin. Reinforcing devices such as the V-shaped stack solder and the castable are additionally arranged in the internal spraying device of the vertical roller mill, so that the service life of the water spraying device is improved to about three months from a week in the past; the frequency of stopping the mill to replace the water spraying device is greatly reduced; the labor intensity is reduced; and the running rate of the mill is improved, and the operating production cost of the vertical roller mill is reduced.
Description
Technical field
The utility model relates to a kind of water injector, relates in particular in a kind of roller type vertical mill mill and reinforces wear-resisting water injector.
Background technology
Roller type vertical mill is that manufacture of cement industry and other relevant industries are used for the plant equipment of grinding material.The stable of material bed is to guarantee one of key factor that the grinding end product quality is stable, and water injector is the effective measures of Stabilizing Materials bed in the mill.At present, the supporting interior water injector of mill of roller type vertical mill is a simple sparge pipe, the serious wear that in use causes owing to material, and sparge pipe is very short service life, changes frequently, has had a strong impact on operation rate, and then has affected output.Therefore, by test, water injector improves in the mill of pair roller type Vertical Mill.
Summary of the invention
The utility model has overcome the defective of existing existence, water injector in a kind of roller type vertical mill mill is provided, the more existing water injector of water injector has improved the scuff resistance of water injector in the mill of the improved roller type vertical mill after the improvement, reduced and stopped grinding the frequency of changing water injector, reduce labour intensity, improved the mill running rate.
For achieving the above object, the technical solution adopted in the utility model is as follows:
Water injector in a kind of roller type vertical mill mill, to be consisted of by sparge pipe, cast hopper and V-type built-up welding material, end at sparge pipe is provided with the flange plate that is connected for roller type vertical mill, the other end sealing of sparge pipe, the sparge pipe below is provided with hole for water spraying, V-type built-up welding material is located at the top of sparge pipe, is provided with the cast hopper of a del at the middle part of sparge pipe, is full of wear-resistant castable in the cast hopper.
Be provided with the castable inlet for the can castable in described castable box top.
Described V-type built-up welding material is to be formed by the wear resistance electrode built-up welding.
Described V-type built-up welding material and cast hopper are the bracing means that adds on the water injector.
The beneficial effects of the utility model are:
Add the bracing means such as V-type built-up welding material and cast hopper by water injector in the pair roller type Vertical Mill, service life from an original week of water injector was brought up to about three months, greatly reduced and stopped grinding the frequency of changing water injector, reduced labour intensity, improve the mill running rate, reduced the production cost of the operation of roller type vertical mill.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is further elaborated.
As shown in Figure 1 and Figure 2, water injector is to be made of sparge pipe 1, flange plate 2, cast hopper 3, V-type built-up welding material 8 in a kind of roller type vertical mill mill of the present utility model, flange plate 2 is fixing parts of water injector and roller type vertical mill, be welded on an end of sparge pipe 1, the other end of sparge pipe 1 then seals, the top of sparge pipe 1 is the V-type built-up welding material 8 that forms with the wear resistance electrode built-up welding, and the inclined to one side flange plate in the centre of sparge pipe 12 places are provided with the cast hopper 3 of del.
As shown in Figure 3, be sparge pipe import 6 in the central authorities of the flange plate 2 of water injector, flange plate 2 is provided with flange screw hole 7.
As shown in Figure 4, be provided with castable inlet 5 on cast hopper 3 tops of water injector, wear-resisting castable is filled in the cast hopper 3 thus.
As shown in Figure 5, the below of sparge pipe 1 is provided with hole for water spraying 4.
