Abstract
The utility model discloses a structure on an outer flowing air outlet of a burner, which comprises a pulverized coal channel outer wall pipe and an outer flowing air channel outer wall pipe which is sleeved on the outer portion of the pulverized coal channel outer wall pipe, wherein a ring outer flowing air channel is arranged between the pulverized coal channel outer wall pipe and the outer flowing air channel outer wall pipe, the outer portion of the pulverized coal channel outer wall pipe is sleeved with an integral round ring which is blocked on an outlet of the outer flowing air channel, the ring outer end surface of the outer flowing air channel is fixed on the right end surface of the integral round ring, the integral round ring is provided with 12-24 thread holes, and an outer flowing air nozzle is rotatably arranged in the thread holes. The Structure on the outer flowing air outlet of the burner can prevent an outer flowing air duct of the burner for a rotary cement kiln from deforming in high temperature in the kiln, thereby guaranteeing flame of the burner to be complete and not to lean to one side, and being not capable of generating leaning fire to brush kiln skin. The structure is simple, and the replacement is convenient.
Description
Technical field:
The utility model relates generally to the structure of a kind of cement rotary kiln with burner outflow wind exit.
Background technology:
At present, cement rotary kiln is generally four-way with burner, is made of outflow wind passage, coal dust passage, interior stream wind passage and center wind duct.Cement rotary kiln grog firing temperature is 1450 ℃, and its flame temperature is higher.Cement rotary kiln is the circumferential weld structure with its outflow wind of burner at present, and the outer wall of outflow wind passage adopts heat resisting cast steel, and its material is generally 0Cr25Ni20, the general 20～25mm of wall thickness.Yielding under the high temperature in kiln, cause partially fire brush kliner coating, it is smooth, even to influence kliner coating, and then influences refractory brick service life.
The utility model content:
The utility model purpose is exactly yielding under the high temperature in kiln with burner outflow air channel in order to overcome existing cement rotary kiln, the structure in a kind of burner outflow wind exit is provided, this structure can guarantee to outflow wind outlet be positioned at all the time with the concentric annulus of burner on, thereby guarantee the complete not sideslip of flame.
The utility model is achieved through the following technical solutions:
The structure in a kind of burner outflow wind exit, include coal dust channel outer wall pipe and be enclosed within the outer outflow wind channel outer wall pipe of coal dust channel outer wall pipe, be formed with the outflow wind passage of annular between described coal dust channel outer wall pipe and outflow wind channel outer wall pipe, it is characterized in that: the outer fixed cover of described coal dust channel outer wall pipe is equipped with the whole annulus of retaining at outflow wind channel exit, the annular outer face of described outflow wind channel outer wall pipe is fixed on the right side of whole annulus, have 12-24 screwed hole on the described whole annulus, be installed with outflow wind nozzle in the described screwed hole.
Described structure is characterized in that: a described 12-24 screwed hole all be positioned at the concentric annulus of burner center line on.
Described structure is characterized in that: between described whole annulus and coal dust channel outer wall pipe by being threaded.
Described structure is characterized in that: whole annulus adopts 0Cr25Ni20 heat resisting steel to forge to make and forms.
The utility model wind channel outer wall that will outflow is designed to whole annulus with pipe coal dust channel outer wall pipe in the exit, on annulus, open 12-24 screwed hole, all screwed holes be positioned at the concentric annulus of burner on, 12-24 outflow wind nozzle is screwed into respectively in the corresponding screwed hole.Outflow wind is by the centre bore ejection of outflow wind nozzle.Whole annulus adopts 0Cr25Ni20 heat resisting steel to forge and makes, and has thoroughly eliminated the inevitable casting flaw of heat resisting steel foundry goods.The thick 75mm that reaches of described whole annulus, thus sturdy and durable, can guarantee that whole annulus is indeformable, therefore also just guarantee the exogenous wind nozzle be positioned at all the time with the concentric annulus of burner on, fire can not take place partially and brush kliner coating in thereby the complete not sideslip of burner flame.In addition owing to outflow wind nozzle and whole annulus threaded connection, so change conveniently.
The utility model has the advantages that:
The utility model can avoid cement rotary kiln to be out of shape under the high temperature in kiln with burner outflow air channel, thereby guarantees the complete not sideslip of burner flame, and fire brush kliner coating partially can not take place.And simple in structure, it is convenient to change.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is an outflow wind structure of nozzle schematic diagram.
The specific embodiment:
The structure in a kind of burner outflow wind exit, include coal dust channel outer wall pipe 4 and be enclosed within coal dust channel outer wall pipe 4 outflow wind channel outer wall pipe 3 outward, described coal dust channel outer wall pipe 4 and 3 outflow wind passages that are formed with annular of outflow wind channel outer wall pipe, the coal dust channel outer wall pipe 4 outer whole annulus 2 that are installed with retaining at outflow wind channel exit, whole annulus 2 adopts 0Cr25Ni20 heat resisting steel to forge to make and forms.The annular outer face of described outflow wind channel outer wall pipe 3 is fixed on the right side of whole annulus 2, has 16 screwed holes on the described whole annulus 2, described 16 screwed holes all be positioned at the concentric annulus of burner center line on.Be installed with outflow wind nozzle 1 in the described screwed hole.
Claims (4)
1. the structure in burner outflow wind exit, include coal dust channel outer wall pipe and be enclosed within the outer outflow wind channel outer wall pipe of coal dust channel outer wall pipe, be formed with the outflow wind passage of annular between described coal dust channel outer wall pipe and outflow wind channel outer wall pipe, it is characterized in that: the outer fixed cover of described coal dust channel outer wall pipe is equipped with the whole annulus of retaining at outflow wind channel exit, the annular outer face of described outflow wind channel outer wall pipe is fixed on the right side of whole annulus, have 12-24 screwed hole on the described whole annulus, be installed with outflow wind nozzle in the described screwed hole.
2. structure according to claim 1 is characterized in that: a described 12-24 screwed hole all be positioned at the concentric annulus of burner center line on.
3. structure according to claim 1 is characterized in that: between described whole annulus and coal dust channel outer wall pipe by being threaded.
