Abstract
The utility model relates to a multilevel impeller fan strong wind suction dust collector, comprising a dust collector housing, a dust collector air inlet on the dust collector housing, a cover cap, a dust collector air outlet on the cover cap, a dust collector multilevel fan component fixed on the centre of the cover cap and arranged on the center of the dust collector housing, and a filter fixed on the center of the cover cap and arranged outside the dust collector fan component; wherein, the dust collector fan component comprises a motor component arranged at the upper part, a fan impeller fixed on the motor shaft and rotated along the motor shaft, a duct component above the fan impeller without rotating along the motor shaft, and a fan impeller chimney outside the duct component and the fan impeller. The utility model has the advantages: due to applying the multilevel impeller fan, a high negative pressure can form in the dust collector housing, and the dust collector can keep normal operation when dust on the filter surface is rather thick and resistance is rather large; due to that the dust collector air inlet is arranged in the tangential direction of the dust collector housing, the inlet air can form cyclone in the dust collector housing, and the work efficiency of the dust collector is improved.
Description
Technical field
The utility model relates to a kind of dust arrester, the strong air draught dust arrester of particularly a kind of multi-stage impeller blower fan.
Background technology
Dust arrester is widely used in the cleaning control of dust of environment such as family, office, factory at present.Dust arrester structure style of the prior art is numerous, and its beneficial effect also has his own strong points, and defective also has nothing in common with each other.It is big to lack a kind of air draught power in the prior art, and particularly more when the dust arrester control of dust, the industrial processes that the air draught resistance still can work on when big is with strong air draught dust arrester.
Summary of the invention
In order to solve the deficiencies in the prior art, the utility model discloses a kind of dust arrester that is provided with multistage draught fan impeller.Because multistage draught fan impeller is set, fans entrance can form high negative, and is more when the dust arrester control of dust, when particularly the filter surfaces control of dust is thicker, still can work on.
The utility model for the technical scheme that solves the technical problem that exists in the prior art and take is: a kind of strong air draught dust arrester by dust collector body, be positioned at dust arrester air inlet, cover cap on the dust collector body, be positioned at dust arrester gas outlet on the cover cap, be fixed in dust arrester fan assembly that the cover cap bottom is positioned at the dust collector body center, be fixed in the cover cap bottom and be positioned at the outer filter of dust arrester fan assembly and constitute, it is characterized in that: the dust arrester fan assembly is to be made of multistage draught fan impeller blower fan.
The core component dust arrester fan assembly of strong air draught dust arrester is by superposed electric motor assembly, be fixed on the motor reel draught fan impeller of two-stage at least that can rotate with motor reel, lay respectively at the ducting assembly of two-stage at least that do not rotate with motor reel the draught fan impeller top, lay respectively at ducting assembly and the outer draught fan impeller of the two-stage at least cover of draught fan impeller does not constitute.
Noise when working in order to reduce dust arrester is provided with acoustic material above the electric motor assembly of dust arrester blower fan in the cover cap.
In order to reduce the filter surfaces control of dust, increase dust collecting effect, the dust arrester air inlet is positioned at the tangential direction on dust collector body top.
The beneficial effects of the utility model are; Owing to adopted the multi-stage impeller blower fan, can form high negative pressure in the dust collector body, under the situation thicker at the filter surfaces control of dust, that resistance is bigger, but operate as normal still; The dust arrester air inlet is arranged on the tangential direction of dust collector body, makes air intake form whirlwind in dust collector body, and under action of centrifugal force, oarse-grained control of dust can descend along the dust collector body inwall, reduces the filter surfaces control of dust, improves the dust arrester operating efficiency.The utility model is particularly useful for the supporting use dust arresters of woodworking machinery such as wood working band sawing machine, circular sawing machine, planer.

The specific embodiment
Embodiment is an example with two-stage draught fan impeller blower fan:
First step assembling dust arrester fan assembly (4): the axle journal end at electric motor assembly (9) assembles second level ducting assembly (10 successively
b), axle sleeve (11), planchet (12), second level draught fan impeller (13
b), planchet (12), second level draught fan impeller cover (14
b), first order ducting assembly (10
a), axle sleeve (11), planchet (12), first order draught fan impeller (13
a), planchet (12), first order draught fan impeller cover (14
a), fixedly fasten nut (15) and two-stage draught fan impeller cover (14).
Second step assembling complete machine: dust arrester air inlet (1) tangentially is set on the top of dust collector body (8); The fixing dust arrester fan assembly (4) in the bottom of cover cap (6) makes the bottom that is positioned at cover cap (6) at electric motor assembly (9); Filter (3) is enclosed within draught fan impeller cover (14) outside of dust arrester fan assembly (4), is fixed in the bottom of cover cap (6); In the cover cap (6), acoustic material (5) is set above the electric motor assembly (9), the complete machine assembling is finished.
Its course of work is like this: owing to running up of dust arrester fan assembly (4), control of dust space (7) produces negative pressure, dusty gas enters through dust arrester air inlet (1), because dust arrester air inlet (1) is arranged on the tangential direction of dust collector body (8), make air intake in control of dust space (7), form whirlwind, under action of centrifugal force, oarse-grained control of dust can descend along dust collector body (8) inwall.Behind dusty gas process filter (3) filtration, purification, Purge gas enters first order draught fan impeller (13
a), via first order ducting assembly (10
a) enter second level draught fan impeller (13
b), via second level ducting assembly (10
b) the Purge gas motor winding winding that enters electric motor assembly (9) cools to electric motor assembly (9), discharges from dust arrester gas outlet (2), the control of dust process is finished.
