Abstract
The utility model discloses a kind of cyclone dust collectors, including body of deduster, the body of deduster includes the hollow stage body shape chimney fan for entering air duct, being arranged at air intake tube inner chamber one end, chimney fan is provided with middle cavity, the small-caliber end of chimney fan is towards air intake tube inner chamber, the air-out drum outer wall is provided with the oblique projection of reversed acanthoid, the oblique raised stretching heavy caliber end of the direction towards chimney fan.The utility model passes through oblique raised setting, the air-flow for being present in air-out drum outer wall and entering between air duct inwall is upset, avoid the formation of whirlpool, prevent dust laden air from flowing back, and then avoid dust laden air with clean primary air enter chimney fan in cavity, ensure from discharge pipe discharge air it is purer.
Description
Technical field
It the utility model is related to a kind of cyclone dust collectors.
Background technology
At present, domestic locomotive generally comprises following structure for the cyclone dust collectors of equipment ventilation filter：
Enter air duct, the round estrade for being arranged at the cyclone blade of air intake tube inner chamber one end, being arranged at the air intake tube inner chamber other end
Air duct, the discharge pipe docked with round estrade air duct, round estrade air duct position is corresponded on air intake barrel and is provided with dust-exhausting port.
Air is spun up after being pressed into air duct in blade, and under the action of the centrifugal force, dust is concentrated mainly on into air duct
Periphery of inner wall, cleaned air are discharged from round estrade air duct center.But following defect in actual moving process be present：
In round estrade air duct side wall and enter in the region between air duct inwall, the air containing dust can form whirlpool, whirlpool
Whirlpool causes dust laden air to flow back, and then enters round estrade air duct with primary air and discharge so that under the air purity of discharge pipe
Drop.That is the poor filtration effect of whole cyclone dust collectors, the fine ash in whirlpool low especially for the efficiency of dust collection of fine ash
Easily enter round estrade air duct.
Utility model content
In view of the above-mentioned problems, the utility model aims to provide a kind of cyclone dust collectors of good filtration effect.
The utility model solve problem technical scheme be：A kind of cyclone dust collectors, including body of deduster, the dedusting
Device body includes the hollow stage body shape chimney fan for entering air duct, being arranged at air intake tube inner chamber one end, and chimney fan is provided with middle cavity, gone out
For the small-caliber end of air duct towards air intake tube inner chamber, the air-out drum outer wall is provided with the oblique projection of reversed acanthoid, and this is oblique raised to stretch
Outgoing direction is towards the heavy caliber end of chimney fan.
Such scheme has upset the gas for being present in air-out drum outer wall and entering between air duct inwall by oblique raised setting
Stream, avoids the formation of whirlpool, prevents dust laden air from flowing back, and then avoids it from entering cavity in chimney fan.
Preferably, the tiltedly protruding ring is circumferentially disposed around chimney fan outer wall.
Specifically, the body of deduster also includes the cyclone blade for being arranged at the air intake tube inner chamber other end, entering air duct
Chimney fan position is corresponded on wall and is provided with dust-exhausting port；
It is described enter air duct installation cyclone blade one end to being connected to blast pipe, chimney fan heavy caliber end is to being connected to discharge pipe.
The dust laden air for being present in air-out drum outer wall and entering between air duct inwall is discharged from dust-exhausting port.
Further, radome fairing is provided with the one end for entering close blast pipe in air duct, the radome fairing is hemispherical.Radome fairing
Enable to air inlet evenly.
Preferably, the cyclone blade is provided with 4, and cyclone blade length is into 1.2 times of air duct internal diameter.
Preferably, the tiltedly raised angle with chimney fan axis is [60 °, 70 °].
The utility model has upset the gas for being present in air-out drum outer wall and entering between air duct inwall by oblique raised setting
Stream, avoids the formation of whirlpool, prevents dust laden air from flowing back, and then avoid dust laden air and enter air-out with clean primary air
Cylinder in cavity, ensure from discharge pipe discharge air it is purer.
Brief description of the drawings
The utility model is described in further detail below in conjunction with the accompanying drawings.
Fig. 1 is the utility model cyclone dust collectors sectional view.
Fig. 2 is Fig. 1 left view.
In figure：1- radome fairings, 2- cyclone blades, 3- enter air duct, and 4- blast pipes, 5- dust-exhausting ports, 6- is tiltedly raised, 7- air-out
Cylinder, 8- discharge pipes.
Embodiment

2.The position of chimney fan 7 is corresponded on the wall of air duct 3 is entered and is provided with dust-exhausting port 5.Chimney fan 7 is provided with middle cavity, the small-caliber end of chimney fan 7
Direction enters the inner chamber of air duct 3.It is described enter air duct 3 install cyclone blade 2 one end to being connected to blast pipe 4.The heavy caliber end pair of chimney fan 7
It is connected to discharge pipe 8.
Radome fairing 1 is provided with entering one end in air duct 3 close to blast pipe 4, the radome fairing 1 is hemispherical.
The cyclone blade 2 is provided with 4, and the length of cyclone blade 2 is into 1.2 times of the internal diameter of air duct 3.
The outer wall of chimney fan 7 is provided with oblique raised the 6 of reversed acanthoid.This oblique raised 6 stretches out direction towards chimney fan 7
Heavy caliber end.The tiltedly projection 6 is circumferentially disposed around the outer wall of chimney fan 7.The tiltedly projection 6 and the angle of the axis of chimney fan 7 are
[60°,70°]。
Extraneous air enters from blast pipe 4, first passes through radome fairing 1, during by cyclone blade 2, the powder in air and air
Dancing dervish turns and accelerated.Under the action of the centrifugal force, dust is concentrated mainly on into the periphery of inner wall of air duct 3, about 5%~10% dust laden air
By the outer wall of chimney fan 7 and the space entered between the inwall of air duct 3, discharged from dust-exhausting port 5, pure air is hollow from chimney fan 7
