Abstract
The present invention relates to a novel internal and external combined corrugated pipe which comprises an external corrugated pipe and an internal corrugated pipe, wherein the internal corrugated pipe is arranged in the middle in the external corrugated pipe; a sand washing channel is arranged between the external corrugated pipe and the internal corrugated pipe; the internal wall of the external corrugated pipe is a smooth surface; the external corrugated pipe is composed of a semi-sheet structure body; connecting ends are arranged on the semi-sheet structure body; connecting holes are formed in the connecting ends; the external corrugated pipe is composed of internal triangular sections and external straight sections; the internal corrugated pipe is composed of external triangular sections and internal straight sections; the external triangular sections of the internal corrugated pipe are arranged in the middles of the external straight sections of the external corrugated pipe; and the sand washing channel is arranged between the external straight sections of the external corrugated pipe and the external triangular sections of the internal corrugated pipe. The pipe has a good sand washing effect and lighter overall mass and is formed integrally.
Description
Technical field
The present invention relates to a kind of sand-washing device corrugated tube, be specifically related to a kind of Combined corrugated pipe.
Background technology
Shifting sand filter is a kind of continuous print filter continuously, and it need not shut down and rinses or backwash.Water inlet adverse current is upwardly through casting bed, and filter sand moves down simultaneously.While filtering, the filter sand of pollution cleans up in sand-washing device, and float is got rid of via rinse water.
Existing sand-washing device corrugated tube is all straight-through structure, and the washed-out sand time is shorter, and washed-out sand effect is undesirable.Further, owing to being the problems such as human weld forms, and it is uneven that it exists size, heavier mass, actual operation requirements is not met.
Summary of the invention
Goal of the invention: the invention aims to overcome deficiency of the prior art, it is provided that a kind of washed-out sand is effective, total quality is relatively light, integrated novel inside and outside Combined corrugated pipe.
Technical scheme: in order to solve above-mentioned technical problem, the novel inside and outside Combined corrugated pipe of one of the present invention, it includes outward corrugated tube and inner corrugated pipe, described inner corrugated pipe is located at outward corrugated tube bosom, washed-out sand passage it is provided with between described outward corrugated tube and inner corrugated pipe, the inwall of described outward corrugated tube is shiny surface, described outward corrugated tube is made up of half chip structural body, described half chip structural body is provided with connection end, described connection end is provided with connecting hole, described outward corrugated tube is made up of Triangle ID section and outer flat segments, described inner corrugated pipe is made up of outer triangle section and interior flat segments, the outer triangle section of described inner corrugated pipe is located in the middle part of the outer flat segments of outward corrugated tube, it is described washed-out sand passage between outer flat segments and the outer triangle section of inner corrugated pipe of described outward corrugated tube.
Described outward corrugated tube and inner corrugated pipe are all fiberglass corrugated tube.
Described connection end is located at the Triangle ID section of described outward corrugated tube.
The cross sectional shape of described washed-out sand passage is double W symmetric figures.
The operation principle of shifting sand filter is continuously: former water distributes into filter by inlet channel and eight pawl water-locators, former water is risen by the mobile casting bed constantly declined, filter liquor is discharged via the effluent pipe mouth above overflow weir and filter, dirty sand is risen in the sand-washing device of filter top by the air lift of filter bottom, then inversely clean through upper strata filtrate when sand-washing device corrugated tube moves down, clean sand after cleaning falls back on the surface on filter casting bed, again participating in filtering, the washed-out sand water being mingled with solid suspension is discharged through useless outlet.
When filter sand is lowered through sand-washing device, filter sand is forced to do eddy motion, simultaneously suffers the filtrate stream of rising.Impurity in filter sand will be rinsed totally, and flow out with the rinse water risen.Clean current to be produced by rinse water liquid level difference between liquid level and the Liquid level container of filter liquor in filter cabinet.Promotion sub-fraction filtrate is flowed upwardly through sand-washing device by the pressure reduction produced by liquid level difference.Liquid level difference is regulated by two the outlet regulating weirs being fixed on locking knob.Liquid level difference is adjusted to when minimum clean water flow velocity to obtain the sand of cleaning as far as possible.Rinse water flows into collecting container through slit, then discharges through waste water drain.
Beneficial effect: the present invention is compared with prior art, its remarkable advantage is: overall structure of the present invention is simple, described outward corrugated tube and inner corrugated pipe are one-body molded by fiberglass, oeverall quality is lighter, and size uniform, the inwall of described outward corrugated tube uses shiny surface, it is greatly reduced resistance, ensureing that channels open does not blocks, the cross sectional shape of described washed-out sand passage is double W symmetric figures, is effectively increased the washed-out sand time, make cleaning more abundant, described outward corrugated tube is made up of half chip structural body, easy for installation, meets actual operation requirements.
