Description
Technical field
The utility model relates to technical field of cement production, and in particular to a kind of interior water injector of cement vertical mill mill.
Background technique
Cement plant grinds slag powders using Vertical Mill, and sparge pipe can all adhere to hardened a bulk of after operation a period of time, sometimes
Hardened piece excessive will to destroy the bed of material, cause grinding machine operation shakiness to cause to vibrate, can also block water jet sometimes, make amount of water sprayed not
Uniformly, make operator be difficult to grasp suitable parameters, timely and effective cannot adjust；Sparge pipe is made due to material in use
At serious wear, sparge pipe service life is very short, and replacement frequently, has seriously affected operation rate, and then influences yield.
Utility model content
In order to solve above-mentioned the deficiencies in the prior art, the utility model provides a kind of curtain-type air valve.
A kind of interior water injector of cement vertical mill mill, including flange plate, sparge pipe, water spray pipe-in-pipe, described sparge pipe one end
Equipped with the flange plate for connecting with Vertical Mill, the sparge pipe other end is closing and is welded with a screw rod, the sparge pipe centre two
Its axis direction of side is symmetrical arranged there are two link slot, and the link slot is welded for steel plate, and the sparge pipe lower part is equipped with
Several water jets, the water jet are welded with a water spray cap, and the water spray cap top is cylindrical shape, and lower part is cone, institute
It states and is equipped with water passage inside water spray cap, the water spray pipe-in-pipe is the inverted trapezoidal structure that steel plate is welded, the sparge pipe
It is set among casing there are two the connection rib to match with the link slot, the sparge pipe sleeve bottom is opening, the water spray
Pipe-in-pipe is cooperated by connection rib and link slot, is sheathed on outside sparge pipe, the water spray pipe-in-pipe is opened far from one end of flange plate
Equipped with through-hole, the screw rod of the sparge pipe passes through through-hole and is fixed by nuts；
Further, the water spray cap length is 1-1.5cm；
Further, it is 6-8mm that the water spray cap, which crosses water diameter,.
The utility model gain effect is: extending sparge pipe service life, avoids since water spray bottom of the tube knot tying makes to spray
Nozzle blocking.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model,
Fig. 2 is Section A-A schematic diagram in Fig. 1,
Fig. 3 is the utility model sparge pipe structural schematic diagram.
In figure: 1. flange plates, 2. sparge pipes, 21. water spray caps, 22. link slots, 23. screw rods, 3. water spray pipe-in-pipes, 31. connect
Rib.
Specific embodiment
It is practical new to this with reference to the accompanying drawings and examples in order to be more clearly understood that the technical solution of the utility model
Type specific embodiment is described in further detail.The following examples illustrate the utility model, but is not limited to practical
Novel range.
As shown in Figure 1, a kind of cement vertical mill grinds interior water injector, including flange plate 1, sparge pipe 2, water spray pipe-in-pipe 3, institute
2 one end of sparge pipe is stated equipped with the flange plate 1 for connecting with Vertical Mill, 2 other end of sparge pipe is to close and be welded with a screw rod 23,
Described 2 its axis direction of intermediate two sides of sparge pipe is symmetrical arranged there are two link slot 22, the link slot 22 be steel plate weld and
Several water jets are equipped at, 2 lower part of sparge pipe, and the water jet is welded with a water spray cap 21, on the water spray cap 21
Portion is cylindrical shape, and lower part is cone, and water passage is equipped with inside the water spray cap 21, and the water spray pipe-in-pipe 3 is steel plate weldering
Inverted trapezoidal structure made of connecing is set there are two the connection rib 31 that matches with the link slot 22 among the water spray pipe-in-pipe 3,
3 bottom of water spray pipe-in-pipe is opening, and the water spray pipe-in-pipe 3 is cooperated by connection rib 31 and link slot 22, is sheathed on spray
Outside water pipe 2, the water spray pipe-in-pipe 3 offers through-hole far from one end of flange plate 1, and the screw rod 23 of the sparge pipe 2 passes through logical
Hole is simultaneously fixed by nuts；
Preferably, 21 length of water spray cap is 1-1.5cm；
Preferably, it is 6-8mm that the water spray cap 21, which crosses water diameter,.
Working principle: the water in sparge pipe 2 is sprayed onto Vertical Mill through water spray cap 21, is cone because water spray cap 21 is discharged position
Shape does not have water and rests on 2 lower surface of sparge pipe, knot tying phenomenon would not occur with powder in Vertical Mill；By spraying outside sparge pipe 2
Water pipe casing 3 is protected, and can be reduced the abrasion of sparge pipe 2, be extended 2 service life of sparge pipe, when needing replacing water spray pipe-in-pipe 3,
The nut cooperated with 2 end screw rod 23 of sparge pipe need to only be screwed off, remove water spray pipe-in-pipe, more renew, last tightening nut
?.
The utility model structure is simple, easy to use, extends sparge pipe service life, avoids due to bottom of the tube of spraying water
Knot tying blocks water jet.
The above is the better embodiment of the utility model, therefore all according to described in the utility model patent application range
The equivalent change or modification that structure, feature and principle is done, is included in the scope of the utility model patent application.
