The utility model has simple structure and practical values, can provide a large air quantity, high air pressure and reliable performance.
Description
(1) technical field:
The utility model relates to a kind of blower fan, mainly is to be production diphenyl methane-4, and removal system waste gas in the 4`-vulcabond technology guarantees that system pressure designs.
(2) background technique:
At present, produce 160000 tons of diphenyl methanes-4 per year, 4`-vulcabond system needs the waste gas that contains the hydrochloric acid composition of eliminating continuously, the air quantity that present existing blower fan produces is little, blast is low, does not satisfy the needs of system, needs a kind of like this blower fan: air quantity 1500 ~ 3200Nm3/h for this reason, blast 5 ~ 7kPa (G) does not find such blower fan at present as yet.
(3) summary of the invention:
The purpose of this utility model is to overcome the deficiency of above-mentioned prior art and provides a kind of structure fabrication simple and practical, and the air quantity of generation is big, blast height, the blower fan of reliable performance.
The purpose of this utility model can reach by following measure: a kind of blower fan, and it comprises base 3, base 3 is provided with motor 1, it is characterized in that motor 1 coupling shaft 11, base 3 is provided with a support device, and axle 11 flexibly connects with the axle support device, and the front portion of axle 11 connects flashback tank 9, flashback tank 9 is provided with water seal cover plate 10, axle 11 in the flashback tank 9 is provided with water ring 7, and the front end of axle 11 connects impeller 5, and impeller 5 is located in the casing 8, casing 8 links to each other with flashback tank 9, and casing 8 is provided with cover 6.
In order further to realize the purpose of this utility model, described axle support device comprises bearing housing 13, bearing housing 13 is provided with bearing cap 12, bearing gland 16, and axle 11 links to each other with bearing housing 13 by bearing back of the body cap 15, bearing 14, and the axle 11 in the bearing housing 13 is provided with at least one disc 4.
In order further to realize the purpose of this utility model, described disc 4 is two.
In order further to realize the purpose of this utility model, described impeller 5 is half-opened impellers.
In order further to realize the purpose of this utility model, described casing 8, impeller 5 are the glass fibre reinforced plastics material.
The utility model agreement is compared by technology and can be produced following good effect:
Reasonable in design of the present utility model, the sectional area of the width of impeller blade and Fan casing runner is big, and bearing housing is provided with disc, and the rotation of axle is flexible, and rotating speed is fast, reaches the purpose that increases air quantity, and is provided with water ring, and barrier gas is leaked; The parts of casing and all contact gases are glass fibre reinforced plastics, to prevent by gas attack, the reliability of blower fan are increased.
(4) description of drawings:
Accompanying drawing is a structural representation of the present utility model.
(5) embodiment:
Below in conjunction with accompanying drawing preferred forms of the present utility model is elaborated:
Embodiment: a kind of blower fan (referring to accompanying drawing), it comprises base 3, base 3 is provided with motor 1, bearing housing 13, motor 1 is by coupling 2 coupling shafts 11, and axle 11 links to each other with bearing housing 13 by bearing back of the body cap 15, bearing 14, and bearing housing 13 is provided with bearing cap 12, bearing gland 16, axle 11 in the bearing housing 13 is provided with two discs 4, the front portion of axle 11 connects flashback tank 9, and flashback tank 9 is provided with water seal cover plate 10, and the axle 11 in the flashback tank 9 is provided with water ring 7.The front end of axle 11 connects impeller 5, and impeller 5 is located in the casing 8, and casing 8 links to each other with flashback tank 9, and casing 8 is provided with cover 6, and impeller 5 is glass fibre reinforced plastics half-opened impellers, and the parts of casing and all contact gases are the glass fibre reinforced plastics material.
During use, motor is by the rotating speed rotation of coupling drive axle with 2950 rev/mins, the axle impeller is with same speed rotation, impeller is to sucking the gas acting of casing, gas energy is increased get rid of casing, gas is discharged the back and is sucked gas, so circulation again from the outside in the interruption-forming negative pressure of going into of impeller; The effect of casing is that gas is converted into outside the static energy eliminating machine by kinetic energy; The time spent barrier gas of doing of water ring is leaked; The effect of disc is that the oil with bearing housing is thrown to the effect that bearing portion plays lubricated cooling; Impeller is the all-glass fibre reinforced plastic half-opened impeller, and the parts of casing and all contact gases are glass fibre reinforced plastics, to prevent by gas attack.
