Abstract
The utility model relates to a radiation rate increasing device for ladle (foundry ladle) baking nozzles, which is composed of a stepless speed regulation motor, a storage hopper, a material extrusion screw and a material discharging pipe, wherein, the stepless speed regulation motor is connected with the material extrusion screw by a shaft coupler; the top part of the material extrusion screw is provided with the storage hopper; the material extrusion screw is connected with a gas conveying pipe by the material discharging pipe. The utility model increases radiation rate of gas flame, enhances the baking temperature of the ladle (foundry ladle), shortens a half time of baking, and improves the uniformity of the inner wall temperature of the ladle (foundry ladle).
Description
The utility model relates to the baking technology field of ladle and ladle.
Before the utility model is made, in order to improve the baking temperature of ladle and ladle, shorten stoving time, improve the temperature homogeneity of ladle and ladle inwall, people adopt following technical measures usually:
1, increase burner swirl strength and combustion air pressure, it is useful to baking ladle and ladle, but it mainly considers the convection heat transfer' heat-transfer by convection effect, has ignored that radiant heat transfer plays a major role under hot conditions, so the effect of this technology is very limited.
2, adorn a cellular radiant body at the smoke outlet of ladle, with increase radiant heat transfer ability, but this cellular radiant body area is limited, complex structure, and resistance is big, and most flue gas does not pass through radiant body, DeGrain.
3, the combustion-supporting method of pure oxygen, because the purity oxygen source is not enough, and uneconomical.
The purpose of this utility model provides and is used for the device that ladle and ladle baking mouth increases radiance, mainly improves baking temperature by increasing the flame radiation rate, shortens stoving time, improves the uniformity of ladle and ladle inner wall temperature.
Ladle and ladle roasting nozzle increase the radiance device and comprise stepless speed-regulating motor, shaft coupling, storage bin(hopper), material extrusion screw rod and leakage material pipe, wherein stepless speed-regulating motor is connected with the material extrusion screw rod by shaft coupling, one storage bin(hopper) is housed above the material extrusion screw rod, and the material extrusion screw rod is connected with gas pipe by leaking the material pipe.
The operation principle of this device is to start stepless speed-regulating motor to drive the rotation of material extrusion screw rod by shaft coupling, powder that storage bin(hopper) is fallen such as coal dust etc. enter gas conveying tube by leaking the material pipe, under the effect of gas pressure and speed, powder and coal gas spray into ladle or ladle mixed combustion by the burner mouth, to increase the flame radiation rate, realize the purpose of invention.
Major advantage of the present utility model is:
1. strengthen the radianting capacity of gas burner greatly, the baking temperature of ladle or ladle is improved greatly, stoving time can be shortened half.
2. improve the uniformity of ladle or ladle inner wall temperature greatly.
3. increase the calorific capacity of fuel, can use the lower coal gas of calorific value like this.
4. this apparatus structure is simple, and dependable performance is easy to on-the-spot the use.
5. this technology and other technology compatibility are good, can use simultaneously with other technology.
Description of drawings:
Accompanying drawing is the structural representation that ladle and ladle roasting nozzle increase the radiance device.
Number in the figure: 1. stepless speed-regulating motor; 2. shaft coupling; 3. storage bin(hopper); 4. material extrusion screw rod; 5. leak the material pipe; 6. burner; 7. air pipe line; 8. gas conveying tube.
Be described further below in conjunction with the annexation of accompanying drawing structure of the present utility model and each parts:
The utility model comprises stepless speed-regulating motor 1. storage bin(hopper)s 3; Material extrusion screw rod 4 and leakage material pipe 5, wherein stepless speed-regulating motor 1 is connected with material extrusion screw rod 4 by shaft coupling 2, storage bin(hopper) 3 is housed above material extrusion screw rod 4, the material extrusion screw rod is connected with gas conveying tube 8 by leaking material pipe 5, the powder that falls from storage bin(hopper) 3 is by material extrusion screw rod 4, leak material pipe 5 and enter gas conveying tube 8, powder and coal gas mix and become flame by burner and spurt in ladle or the ladle under the effect of gas pressure and speed.
