Abstract
The utility model relates to a rotary sieve, comprising a frame, a cleaning device, a sieve, a guide track, a driving wheel, wherein, an upper frame is provided with the driving wheel, a front guide wheel and a lower guide wheel while a lower frame is provided with a lower chain wheel; the sieve and a chain as a whole are in parallel wound on the driving wheel, the front guide wheel, the lower chain wheel and the lower guide wheel to form a rotary body; the chain of the sieve moves on the guide track on the lower frame and a strong decontaminating mechanism is arranged between the driving wheel and the lower guide wheel. The utility model has the advantages of sieve running stability, flexible operation, easy cleaning, thorough cleaning, drainage convenience, simple structure, and convenient installation and maintenance.
Description
The utility model relates to a kind of water treating equipment, especially a kind of novel rotary sieve.
The water conservancy project machinery that uses in electric power, water conservancy, hydroelectric project is more.Existing filter screen equipment is to utilize sprocket wheel and guide rail to make filter screen along the operation of sprocket wheel and guide rail, be provided with the high pressure water washing pipe on filter screen top and remove contamination, the structures shape of this sewage disposal unit filter screen be not easy to clean.The difficulty of removing contamination and can not be thoroughly clear totally easily causing the secondary pollution of clear water zone be the greatest problem of old-fashioned rotary sieve.
The purpose of this utility model be for provide a kind of filter screen to operate steadily, go slick, clean easily, remove contamination thoroughly, blowdown is convenient, simple in structure, installation, novel rotary sieve easy to maintenance.
The purpose of this utility model can realize by following measure:
A kind of novel rotary sieve comprises frame, washing unit, filter screen, guide rail, motion-work wheel; On top rack, be provided with motion-work wheel, front jockey wheel and following guide deflection sheave; On lower bearing bracket, be provided with lower sprocket; Described filter screen and chain are one and are around on motion-work wheel, front jockey wheel, lower sprocket and the following guide deflection sheave and form revolution that the chain of filter screen also moves on the guide rail on the lower bearing bracket; Between motion-work wheel and following guide deflection sheave, be provided with washing unit in addition.
The utility model has following advantage compared to existing technology:
1, filter screen of the present utility model is around in motion-work wheel and front jockey wheel, lower sprocket, down on the guide deflection sheave, also moves on guide rail when filter screen moves under water, thereby the operating steadily of filter screen, flexible, easy to maintenance.
2, the utility model is owing to move a segment distance behind the wire side, thereby the wire side when filter screen being operated in remove contamination the district down and be in tensioning state, thereby its decontamination direction is consistent with the gravity direction of dirt, is convenient to thoroughly remove contamination.
3, washing unit of the present utility model adopts three grades and removes contamination, and at first with scraper plate 80% dirt is scraped in sewage sump, adopts high pressure water washing then, with rotating cleaning brush or vibrator the tiny dirt of wire side is thoroughly removed again.
4, the utility model is provided with wire side flap and side flap on wire side, can remove dirt fully and enter the contraminated zone, has avoided the secondary pollution to clear water zone.
Structure of the present utility model is provided by the following drawings:
Fig. 1 is a structural representation of the present utility model
Fig. 2 is the utility model right view
Fig. 3 is a washing unit A-A sectional view of the present utility model
Fig. 4 is a B-B sectional view of the present utility model
The utility model is also incited somebody to action in conjunction with the accompanying drawings, and embodiment is described in further detail:
With reference to Fig. 1,2, a kind of novel rotary sieve comprises frame 1,9, washing unit 3, filter screen 7, guide rail 8, motion-work wheel 14; On top rack 1, be provided with motion-work wheel 14, front jockey wheel 10 and following guide deflection sheave 15; Described motion-work wheel 14 is driven by the braking maneuver on the top rack 1, is provided with adjusting device for chains 2 on front jockey wheel 10; On lower bearing bracket 9, be provided with lower sprocket 16; Described filter screen 7 and chain are one and are around on motion-work wheel 14, front jockey wheel 10, lower sprocket 16 and the following guide deflection sheave 15 and form revolution, the also motion on the guide rail on the lower bearing bracket 98 of the chain of filter screen 7, outside guide rail 8, be provided with carrier bar flap 5, on filter screen (7), be provided with ratchet; Between motion-work wheel 14 and following guide deflection sheave 15, be provided with washing unit 3 in addition.Be provided with bottom pollutant baffle plate 6 in addition outside the whole filtering net on lower bearing bracket.
With reference to Fig. 3, described washing unit 3 is that the side at filter screen 7 is provided with high pressure water washing pipe 11 vibrators 12, is provided with cleaning brush 17 and scraper plate 18 and sewage sump 19 at the opposite side of filter screen 7.
With reference to Fig. 4, also be provided with wire side flap 20 and side flap 21, adjustable flap 22 at washing unit 3 places of filter screen 7.
