[accompanying drawing explanation]
Fig. 1 is the structural representation of air inlet device of draught fan in an embodiment.
[detailed description of the invention]
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail.
Fig. 1 is the structural representation of air inlet device of draught fan in an embodiment.This air inlet device of draught fan comprises: coil pipe 100, elevating mechanism 200 and screen pack 300.Coil pipe 100 air inlet inwall is provided with draw-in groove 110, draw-in groove about 110 two ends (relative furred ceiling) all through coil pipe 100.Elevating mechanism 200 is arranged at coil pipe 100 air inlet, is connected with filter 300.Elevating mechanism 200 for filter 300 being promoted with and being assemblied in draw-in groove 110, or by filter 300 by pull down in draw-in groove 110 and under being down to furred ceiling.
Elevating mechanism 200 comprises support 210, runner 220 and lifting rope 230.Support 210 is fixed on the outer wall of coil pipe 100 air inlet, and extends above coil pipe 100.The rotating installation of runner 220 on the bracket 210.Runner 220 side face is provided with race.Lifting rope 230 has certain length, around in the race of runner 220, and can run through coil pipe 100 by the upper and lower side of draw-in groove 110.Lifting rope 230 connects filter 300, utilizes runner 220 to rotate, is promoted by filter 300 and be assemblied in draw-in groove 110, or by filter 300 by under dropping to furred ceiling in draw-in groove 110.
For ensureing that filter is assemblied in draw-in groove 110, do not cause deviating from by draw-in groove 110 because self gravitation pulls lifting rope 230 to make runner 220 rotate, lifting rope 230 is wound around multi-turn in the race of runner 220, or lifting rope 230 adopts metallic cable, as steel wire rope etc.Metallic cable is stuck in race, without under the larger External Force Acting of operating personnel, is not easily elevated voluntarily.
For preventing filter 300 from deviating from further, this elevating mechanism 200 is also included in the fixture arranged below furred ceiling.Lifting rope 230 can be tethered on this fixture, ensures the stable of lifting rope 230.This fixture can be hitching post, annulus, hook etc.
In this embodiment, support 210 is two, is separately fixed at the outer wall both sides of coil pipe 100 air inlet.Support 210 extends the top of draw-in groove 110 upper end.Runner 220 is two, is installed on respectively on support 210.Runner 220 is just to draw-in groove 110.Lifting rope 230 is two, respectively around in runner 220, is connected separately with filter 300.Lifting rope 230 can run through coil pipe 100 by draw-in groove 110 upper and lower side.In a preferred embodiment, lifting rope 230 one end is connected with filter 300 upper end, and the other end is connected with filter 300 lower end.Lifting rope 230 utilizes the rotation of runner 220, carries out oscilaltion to filter 300.
Meanwhile, for making filter 300 more effectively filter, in a preferred embodiment, between filter 300 upper and lower side, width adjusts, and the width between filter 300 upper and lower side is greater than the width between coil pipe 100 upper and lower side.
This air inlet device of draught fan, when unpicking and washing filter, operating personnel pull lifting rope 230, filter 300 is left behind by draw-in groove 110 by lifting rope 230, utilize runner 220 to rotate, filter 300 is down to below furred ceiling, make operating personnel can get filter 300 and clean.After cleaning, operating personnel oppositely pull lifting rope 230, lifting rope 230 drives roller 220 to rotate, and filter 300 is promoted to draw-in groove 110, and is assemblied in draw-in groove 110, thus complete cleaning, operating personnel need not enter among furred ceiling and clean, and avoid repeatedly ascending a height bringing danger to operating personnel, have ensured the safety of operating personnel, convenient, fast, safety, and structure is simple.
In other embodiments, lifting rope 230 one end is connected with filter 300 upper end, and the other end is not connected with filter 300, and can be tethered on fixture.
Or support 210, runner 220 and lifting rope 230 also can be a set of.Support 210 extends the top of draw-in groove 110 upper end.Lifting rope 230 is around in the race of runner 220.Lifting rope 230 can run through coil pipe 100 by draw-in groove 110 upper and lower side, and one end is connected with triangle manner with filter 300 upper end, ensures stable elevation screen pack 300.Lifting rope 230 other end is connected with filter 300 lower end.
Above-mentioned air inlet device of draught fan, when needs clean filter, pull lifting rope by filter by pulling down in draw-in groove and being down to below furred ceiling, make operating personnel can get filter to clean, after cleaning, lifting rope is oppositely pulled to be promoted to draw-in groove, can filter be assemblied in draw-in groove, operating personnel need not enter among furred ceiling and clean, avoid repeatedly ascending a height and bring danger to operating personnel, ensured the safety of operating personnel, improve operating efficiency, convenient, fast, safety, and structure is simple.
The above embodiment only have expressed several embodiment of the present invention, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
