Abstract
The utility model discloses an improved axial-flow draught fan. An electric motor is externally provided with an air cooling and water cooling jacket. The upper part of the water cooling jacket is provided with a water inlet pipe, and the lower part of the water cooling jacket is provided with a jet hole which is used for spraying chilled water into a housing to cool fume and remove dust from the fume. Then, the chilled water is dropped into a dirt discharging groove, and is expelled out of the housing by a dirt discharging pipe. Thus, the utility model can replace a dedicated centrifugal type draught fan to transport high-temperature kiln fume with the dust. The utility model has the advantages of low energy consumption, reasonable and compact structure, and easy fabrication, being able to simultaneously cool the transported kiln fume and remove the dust. The dust draught fan for double cool kiln, oven is a new dust draught fan which has a function of energy-saving and environmental protection and which is suitable for the kiln and the oven to exhaust the fume.
Description
The utility model belongs to a kind of follow-on axial id fan, is specially adapted to the smoke evacuation dedusting of kiln.
In the prior art, any the design's handbook is all stipulated the high-temperature flue gas of dispatch kiln, should adopt special-purpose centrifugal induced draught fan, and the required power of electric motor of this class centrifugal induced draught fan is than higher, and energy consumption is big.Though and common axial id fan energy consumption is lower, because the motor of axial id fan is to place the gas stream that is transferred, it is higher and contain the kiln gas of dust therefore to be not suitable for being used for delivery temperature.
The purpose of this utility model is that the structure of existing axial id fan is improved, and makes it can not only carry high-temperature flue gas, can also carry out dedusting and cooling to the flue gas that is transferred simultaneously.
Enforcement means of the present utility model are to increase an air-cooled chuck outside the motor of axial id fan, at water-cooling jacket of air-cooled chuck outer wall design, cooling water in the water-cooling jacket can enter in the gas pipeline that is transferred by the spray-hole of chuck bottom, and flue gas is carried out cooling and dedusting.
The utility model has the advantages that: replace the high special-purpose centrifugal induced draught fan of power consumption with the dual-cooling kiln dust removing induced draft fan that consumes energy low, be used for the kiln smoke evacuation, can cut down the consumption of energy greatly, have function simultaneously the flue gas ash removal cooling.This dual-cooling kiln dust removing induced draft fan, compact conformation is reasonable, and is easily manufactured, is a kind of novel fan that is suitable for the kiln smoke evacuation with energy-conservation and environmental protection function.
Accompanying drawing is the utility model example structure schematic diagram.
Drawing explanation: 1-casing, 2-impeller, 3-motor, the air-cooled chuck of 4-, 5-water-cooling jacket, 6-water inlet pipe, 7-blast pipe, 8-hole for water spraying, 9-collection wind dirt discharge groove, 10-blow-off pipe, 11-drainpipe.
Embodiment:
Accompanying drawing is the utility model example structure schematic diagram.Its agent structure is similar with common axial id fan, form main body by the impeller 2 and the casing 1 that are installed on the motor 3, its new technical characterictic just is, air-cooled chuck 4 of design outside motor 3, air-cooled chuck 4 is uncovered by an end of impeller 2, directly connects with the negative pressuren zone that draught fan impeller 2 draws, and therefore extraneous cold air can enter air-cooled chuck 4 by blast pipe 7, motor 3 is cooled off, prevent that directly contact is transferred the high temperature of flue gas and causes that motor heats up.Water-cooling jacket 5 of design outside air-cooled chuck 4, water-cooling jacket 5 is introduced cooling water by water inlet pipe 6, and cooling water sprays in the casing 1 through hole for water spraying 8, and the high-temperature flue gas that contains dust that is transferred is carried out cooling and dedusting, fall into dirt discharge groove 9 then, discharge casing 1 by blow-off pipe 10 again.According to concrete needs, also can not open hole for water spraying on the water-cooling jacket, cooling water is by outside the drainpipe 11 discharge machines.
Claims (3)
1, a kind of dual-cooling kiln dust removing induced draft fan that is made of motor, impeller and casing, it is characterized in that: motor is equipped with air-cooled chuck outward.
2, dual-cooling kiln dust removing induced draft fan as claimed in claim 1 is characterized in that: described air-cooled chuck is equipped with water-cooling jacket outward.
3, as claim 1,2 described dual-cooling kiln dust removing induced draft fans, it is characterized in that: on the described water-cooling jacket water inlet pipe is arranged, down hole for water spraying is arranged, cooling water can be sprayed in the casing, fall into dirt discharge groove then and discharge outside the casing by blow-off pipe again.
