Abstract
The utility model relates to a smoke exhausting device of a whirlwind-type quenching tank. The smoke exhausting device of the whirlwind-type quenching tank comprises a quenching tank, a wind exhausting hood and a spiral draught duct, wherein the wind exhausting hood is arranged on one side above the quenching tank; the spiral draught duct is arranged inside the wind exhausting hood; and a draught fan is arranged inside the spiral draught duct. The smoke exhausting device of the whirlwind-type quenching tank is simple in structure; the part right above the quenching tank is not sheltered by a hardware, so that a large component can be moved by a bridge crane and other hoisting equipment and can be directly put into the quenching tank by passing through the upper part of the quenching tank; and the smoke exhausting device of the whirlwind-type quenching tank can guide smoke into a wind exhausting duct and exhaust the smoke; a whirlwind airflow formed by a spiral draught device can generate a spiral suction effect above the quenching tank to generate a tornado effect, so that the smoke can be smoothly exhausted through an outlet of the wind exhausting hood; and when the draught airflow is strong enough, the smoke exhausting device of the whirlwind-type quenching tank is applicable to lateral smoke exhaustion of a larger quenching tank.
Description
Technical field
The utility model relates to a kind of fume extractor, is specifically related to a kind of cyclone type quenching bath fume extractor.
Background technology
Some heavy partss when quenching, in order to be transported to quenching bath to part from process furnace, need be used crane for hoisting in thermal treatment.So extraction hood can not be installed in the top of quenching bath, and the quenching bath size of heavy parts is very big, and common side suction smoke exhaust method can only be taken a small amount of flue gas away, and a large amount of flue gases can directly rise, and pollute, and do not have this type of thermal treatment pond fume exhaust system at present.
Summary of the invention
The utility model technical problem to be solved is to overcome the prior art deficiency, and a kind of cyclone type quenching bath fume extractor is provided, when this device can solve heavy parts thermal treatment, and the discharge problem of quenching flue gas.
The technical scheme of the utility model: a kind of cyclone type quenching bath fume extractor; It comprises quenching bath, exhaust hood, spiral air-inducing passage; One side of quenching bath top is provided with exhaust hood, and spiral air-inducing passage is arranged in the exhaust hood, is provided with induced draft fan in the spiral air-inducing passage.One side of described quenching bath top can be provided with two above exhaust hoods.
The utility model compared with prior art has following beneficial effect: the utility model is simple in structure, and no hardware blocks directly over quenching bath, can use weight handling equipment such as bridge crane to move heavy parts, directly puts into quenching bath through the quenching bath top.This device can be introduced exit duct with flue gas and discharge.Because the cyclonic air flow that spiral air inducing device forms can produce the spiral suction function above the quenching bath side, produce the tornado effect, discharge flue gas smoothly through the outlet of exhaust hood.When air inducing stream is enough strong, can adapt to more large-scale quenching bath side smoke evacuation.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
A kind of cyclone type quenching bath fume extractor, it comprises quenching bath 1, exhaust hood 2, spiral air-inducing passage 3, and a side of quenching bath 1 top is provided with exhaust hood 2, and spiral air-inducing passage 3 is arranged in the exhaust hood 2, is provided with induced draft fan in the spiral air-inducing passage 3.
When large piece has been put into quenching bath 1, can produce a large amount of flue gases at this moment, form flue gas flow 6.The air inducing stream that induced draft fan produces is under spiral air-inducing passage 3 effects, and it is distinguished and admirable to form spiral, i.e. the cyclonic air flow 5 of quenching bath top; Flue gas flow 6 runs into cyclonic air flow 5 when rising; The meeting movement therewith because of the characteristics of cyclonic air flow, accelerates its movement velocity gradually; And the motion of an edge air-flow 4 directions, on one side to the whirlwind central motion.Finally be introduced in spiral air-inducing passage 3, flue gas is discharged smoothly.
Claims (2)
1. cyclone type quenching bath fume extractor; It comprises quenching bath, exhaust hood, spiral air-inducing passage; A side that it is characterized in that the quenching bath top is provided with exhaust hood, and spiral air-inducing passage is arranged in the exhaust hood, is provided with induced draft fan in the spiral air-inducing passage.
2. cyclone type quenching bath fume extractor according to claim 1 is characterized in that a side of described quenching bath top can be provided with two above exhaust hoods.
