Abstract
The utility model relates to a suction nozzle of suction dredger in irrigation engineering machine. The utility model is characterized in that a flat big mouth is arranged at the cavity at the middle of the dredger, and a plurality of clapboards are arranged in the cavity of the suction nozzle. The cavity of the big suction nozzle is divided into a plurality of channels according the flow velocity through clapboards; the channels positioned at middle are of high flow velocity and smaller width; the channels near to the two ends of the suction nozzle are of low flow velocity and large width; so all the channels are of same mud flow. When the utility model is used, a plurality of suction nozzles are arranged in a row along the bottom of pool; and when the suction dredger scratches and sucks mud linearly, and the suction dredger scratches mud as the suction dredger sucks mud; the work procedure that the suction dredger scratches mud before the suction dredger sucks mud so that the time that active mud stops in sewage pool is reduced. The utility model can suck mud directly, quickly and thoroughly, and can effectively enhance density of discharged mud and water quality; the utility model is of high work efficiency and can be used with siphon, pump, and driving type dredger.
Description
Technical field
The utility model relates to a kind of suction nozzle technology of water engineering machinery suction dredge.
Background technology
At present, in sewage treatment project, the domestic less suction dredge of suction nozzle mouth that generally uses adopts multiple spot to inhale mud, needs with scraper plate mud to be scraped to collect earlier to inhale mud mouth, sucking-off then.When this method is used in the sewerage treatment second pond, because sediment is an activated sludge in the pond, the motility of activated sludge is good and to scrape the mud effect relatively poor, therefore this multiple spot suction mud mode of afterwards inhaling of scraping is earlier inhaled the mud poor effect, cause the time of staying of activated sludge at the bottom of the pond to prolong, easily cause and turn over the pond phenomenon, face often floating foam in pond is more.
Summary of the invention
The purpose of this utility model provides a kind of and inhales the supporting use of mud, can thoroughly remove the suction dredge suction nozzle of mud.
The purpose of this utility model is achieved in that the suction dredge suction nozzle, and characteristics are big mouth bodies of flat of cavities in being provided with, establish some dividing plates at the inner chamber of nozzle body.
The utility model is separated into a plurality of passages with big suction nozzle inner chamber by velocity flow profile by dividing plate, and fast at the passage flow velocity of centre, width is less; Passage flow velocity by the suction nozzle two ends is slow, and channel width is bigger, thereby makes each passage inhale mudflow amount unanimity.A plurality of suction nozzles proper alignment at the bottom of the pond becomes a row during use, when suction dredge moves, forms linearity and scrape mud, inhale mud at the bottom of the pond, inhales while scraping, and changes and scrapes the workflow of inhaling mud behind the mud in the prior art earlier, makes activated sludge shorten the time of staying in sewage reservoir.It is direct that the utility model is inhaled mud, thoroughly, can effectively improve spoil disposal concentration and effluent quality rapidly, and high efficiency can be inhaled with siphon, pump and supporting uses such as peripheral driving type suction dredge.
In addition, the lower end of the big mouth body of the utility model connects cleaning shoe, improves the stirring to mud, makes to inhale the raising of mud speed.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the left side view of Fig. 1.
Among the figure, the 1st, big mouth body, 2,3,3 ', 4,4 ' be dividing plate, the 5th, cleaning shoe, 6 adpting flanges.
Specific embodiment
Lumen centers position at the big mouth body 1 of flat is connected with dividing plate 2, be symmetrical arranged dividing plate 3 in dividing plate 2 two sides, dividing plate 4, dividing plate 3 ', dividing plate 4 ', dividing plate 2 is identical with the passage of dividing plate 3 ' composition with passage and dividing plate 2 that dividing plate 3 is formed, width is less, passage that dividing plate 3 and dividing plate 4 formed and dividing plate 3 ' identical with the passage of dividing plate 4 ' compositions, width is bigger, owing to lean on the flow velocity of centre fast, channel width is little, flow velocity by big mouth body 1 both sides is slow, and channel width is bigger, thereby makes the suction mudflow amount unanimity of each passage.Cleaning shoe 5 is fixedlyed connected with a long limit of mouth body 1, and the lower edge of cleaning shoe 5 is linear or zigzag.
Upper limb in big mouth body 1 is provided with adpting flange 6.
Claims (4)
1, suction dredge suction nozzle, the big mouth body of flat of cavities is established some dividing plates at the inner chamber of nozzle body in it is characterized in that being provided with.
2,, it is characterized in that the lower end of big mouth body connects cleaning shoe according to the described suction dredge suction nozzle of claim 1.
3,, it is characterized in that described cleaning shoe lower edge indention according to the described suction dredge suction nozzle of claim 2.
