Abstract
The utility model discloses an air supply device with a dual-ring baffle on a shell of a rotary kiln, which relates to the improvement of an air supply device structure on the shell of the rotary kiln. The utility model aims to provide a ventilation device with the dual-ring baffle on the shell of the rotary kiln, which can prevent an air supply system from being burnt out and has simple structure. The air supply device comprises the shell; the shell is arranged on carrier roller devices; a gear transmission device and a gear on the shell are meshed; the shell is provided with the air supply device; and the air inlet of the air supply device is connected with an air supply nozzle through a fan and an air supply pipe. The utility model is structurally characterized in that the dual-ring baffle is arranged between the air supply pipe and the nozzle; one end of the dual-ring baffle is a hollowed baffle, and the other end thereof is a solid baffle; the bottoms of the hollowed baffle and the solid baffle are arranged on a common shaft; and the peripheries of the hollowed baffle and the solid baffle are provided with annularly arranged location holes.
Description
Technical field:
The utility model relates to the improvement of the air-supply arrangement structure on the cylindrical shell of rotary kiln.
Background technology:
The air-supply arrangement of traditional rotary kiln nozzle can occur and damage phenomenon in the running of rotary kiln, do not change if do not stop kiln, and material enters air supply duct along the nozzle that damages in the very fast kiln, and then burns out supply air system; Stop kiln and change nozzle, the time is longer, can cause production to have a strong impact on.
Summary of the invention:
The utility model is exactly at the problems referred to above, and the air-supply arrangement on a kind of cylindrical shell that prevents to burn out supply air system, the rotary kiln with dicyclo baffle plate simple in structure is provided.
For achieving the above object, the utility model adopts following technical scheme, and the utility model comprises cylindrical shell, and cylindrical shell places on the support roller device, and gear drive is meshed with gear on the cylindrical shell, and cylindrical shell is provided with air-supply arrangement; The air inlet of described air-supply arrangement links to each other with wind pushing nozzle by blower fan, ajutage, its structural feature is provided with the dicyclo baffle plate between ajutage and nozzle, one end is the hollow out baffle plate, the other end is solid baffle plate, hollow out baffle plate, solid baffle plate bottom are arranged on the common axis, have the locating hole of annular array on the periphery of hollow out baffle plate, solid baffle plate.
The utility model beneficial effect:
The utility model is provided with the dicyclo baffle plate between ajutage and nozzle; When operate as normal, the hollow out baffle plate is fixed on the ajutage; In case when the nozzle damage took place, solid baffle plate can forward on the pipeline of ajutage around axle, can stop the wind that returns of rotary kiln to damage air-supply arrangement along ajutage.
Description of drawings:
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is the utility model structural representation;
Fig. 2 is the A-A cutaway view of Fig. 1;
Fig. 3 is the partial enlarged drawing of Fig. 1.
The specific embodiment:
As shown in the figure, the utility model comprises cylindrical shell 1, and cylindrical shell 1 places on the support roller device 3, and gear drive 9 is meshed with gear 2 on the cylindrical shell 1, and cylindrical shell 1 is provided with air-supply arrangement; The air inlet 4 of described air-supply arrangement links to each other with wind pushing nozzle 11 by blower fan 5, ajutage 6, between ajutage 6 and nozzle 11, be provided with the dicyclo baffle plate, one end is a hollow out baffle plate 7, the other end is solid baffle plate 8, hollow out baffle plate 7, solid baffle plate 8 bottoms are arranged on the common axis 13, have locating hole 12 on the periphery of hollow out baffle plate 7, solid baffle plate 8.
Hollow out baffle plate 7, solid baffle plate 8 can be fixed between ajutage 6 and the nozzle 11 by flange 10 respectively.
During use, under the normality, hollow out baffle plate 7 is fixed on the ajutage 6; When nozzle 11 damages took place, solid baffle plate 8 forwarded on the ajutage 6 around common axis 13; Unclamp the connecting bolt on the flange 10, by locating hole 12 solid baffle plate 8 is fixed in the ajutage 6, what can stop rotary kiln returns the destruction of wind to air-supply arrangement.
