Description
Technical field
The utility model relates to a kind of sand-washing device bellows, is specifically related to a kind of Combined corrugated pipe.
Background technique
Continuous Flow sand filter is a kind of continuous print filter, and it does not need to shut down rinses or backwash.Water inlet adverse current is upwards by casting bed, and filter sand moves down simultaneously.While filtration, the filter sand of pollution cleans up in sand-washing device, and suspended matter is got rid of via rinse water.
Existing sand-washing device bellows 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 purpose of this utility model is to overcome deficiency of the prior art, provides a kind of washed-out sand effective, total quality is comparatively light, integrated novel inside and outside Combined corrugated pipe.
Technological scheme: in order to solve the problems of the technologies described above, the novel inside and outside Combined corrugated pipe of one described in the utility model, it comprises outward corrugated tube and inner corrugated pipe, described inner corrugated pipe is located at outward corrugated tube bosom, washed-out sand passage is provided with between described outward corrugated tube and inner corrugated pipe, the inwall of described outward corrugated tube is smooth surface, described outward corrugated tube is made up of half chip structural body, described half chip structural body is provided with connecting end, described connecting end is provided with attachment 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, be described washed-out sand passage between the outer flat segments of described outward corrugated tube and the outer triangle section of inner corrugated pipe.
Described outward corrugated tube and inner corrugated pipe are all glass fibre reinforced plastics bellows.
Described connecting end is located at the Triangle ID section place of described outward corrugated tube.
The sectional shape of described washed-out sand passage is two W symmetric figures.
The working principle of Continuous Flow sand filter is: former water enters filter by intake pipe and the distribution of eight pawl water-dispensing devices, 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 rises in the sand-washing device of filter top by the air lift of filter bottom, through the reverse cleaning of upper strata filtrate when then moving down from sand-washing device bellows, clean sand after cleaning falls back on the surface on filter casting bed, again participate in filtering, the washed-out sand water being mingled with suspended solid is discharged through useless outlet.
When filter sand is lowered through sand-washing device, filter sand is forced to do eddy motion, runs into the filtrate flow of rising simultaneously.Impurity in filter sand will be rinsed totally, and flow out with the rinse water risen.Cleaning current are produced by the rinse water difference of liquid level between the liquid level of filter liquor in filter cabinet and Liquid level container.Promotion sub-fraction filtrate is upwards flow through sand-washing device by the pressure reduction produced by difference of liquid level.Difference of liquid level is regulated by two the outlet regulating weirs be fixed on locking knob.Difference of liquid level is adjusted to and can obtains as far as possible clean sand when minimum clean water flow velocity.Rinse water flows into collecting container through slit, then discharges through waste water drain.
Beneficial effect: the utility model compared with prior art, its remarkable advantage is: the utility model overall structure is simple, described outward corrugated tube and inner corrugated pipe one-body molded by glass fibre reinforced plastics, oeverall quality is lighter, and size uniform, the inwall of described outward corrugated tube adopts smooth surface, greatly reduce resistance, ensure that channels open does not block, the sectional shape of described washed-out sand passage is two W symmetric figures, effectively improves the washed-out sand time, make cleaning more abundant, described outward corrugated tube is made up of half chip structural body, easy for installation, realistic usage requirement.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model;
Fig. 2 is the structural representation of outward corrugated tube described in the utility model;
Fig. 3 is the structural representation of inner corrugated pipe described in the utility model.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described.
As Fig. 1, shown in Fig. 2 and Fig. 3, the novel inside and outside Combined corrugated pipe of one described in the utility model, it comprises outward corrugated tube 1 and inner corrugated pipe 2, described inner corrugated pipe 2 is located at outward corrugated tube 1 bosom, washed-out sand passage 3 is provided with between described outward corrugated tube 1 and inner corrugated pipe 2, the inwall of described outward corrugated tube 1 is smooth surface 4, described outward corrugated tube 1 is made up of half chip structural body 5, described half chip structural body 5 is provided with connecting end 6, described connecting end 6 is provided with attachment hole 7, described outward corrugated tube 1 is made up of Triangle ID section 8 and outer flat segments 9, described inner corrugated pipe 2 is made up of outer triangle section 10 and interior flat segments 11, the outer triangle section 10 of described inner corrugated pipe 2 is located in the middle part of the outer flat segments 9 of outward corrugated tube 1, be described washed-out sand passage 3 between the outer flat segments 9 of described outward corrugated tube 1 and the outer triangle section 10 of inner corrugated pipe 2, described outward corrugated tube 1 and inner corrugated pipe 2 are all glass fibre reinforced plastics bellows, described connecting end 6 is located at Triangle ID section 8 place of described outward corrugated tube 1, the sectional shape of described washed-out sand passage 3 is two W symmetric figures.The utility model overall structure is simple, described outward corrugated tube and inner corrugated pipe one-body molded by glass fibre reinforced plastics, oeverall quality is lighter, and size uniform, the inwall of described outward corrugated tube adopts smooth surface, greatly reduces resistance, ensures that channels open does not block, the sectional shape of described washed-out sand passage is two W symmetric figures, effectively improve the washed-out sand time, make cleaning more abundant, described outward corrugated tube is made up of half chip structural body, easy for installation, realistic usage requirement.
