Abstract
The utility model discloses a kind of air Continuous Flow sand filter and carry sand device, comprise, sand extraction tube, is wrapped in the main body cover in sand extraction tube outside; Between described sand extraction tube and main body cover, be provided with screen pack; Described sand extraction tube is provided with venthole; Described main body cover is provided with air admission hole.The disclosed air Continuous Flow of the utility model sand filter is carried sand device, simple in structure, and filtered wastewater that can be rapidly and efficiently, prevents that sand filter course from hardening.
Description
Technical field
The utility model relates to a kind of sewage disposal device accessory, and particularly a kind of air Continuous Flow sand filter is carried sand device.
Background technology
Continuous Flow sand filter is a kind of environmental protection equipment, and its function is that the sewage before discharge is done to last filtration, reaches the up-to-date discharge standard of country.Continuous Flow sand filter is that sewage is passed through to the casting bed of two meters of thickness, utilizes the superfine little dirt in sand energy adsorbed water to reach national up-to-date discharge standard.The circulation of sand relies on the effect of air-lift unit, water and dirty sand are slided up and down along sand extraction tube, due to the acutely friction under compressed-air actuated effect of air, water, sand, the foreign material wash-out that sand is held back, at pipeline air, be released, dirty rinse water stream removes by rinse water row of conduits, and sand after cleaning adds in filter bed from top to bottom because of gravity.
In this process, carry sand pump and determined the vital quality of complete equipment, if carry sand pump, can not to use or put forward sand effect bad, and that sand cannot flow, cannot clean, dirt in sand adsorbed water will get more and more, and finally will harden and cause a whole set of filtration system normally to use.
Utility model content
Goal of the invention: for the deficiencies in the prior art, the utility model discloses a kind of air Continuous Flow sand filter that prevents that sandstone filter course from hardening and carry sand device.
Technical scheme: the utility model discloses a kind of air Continuous Flow sand filter and carry sand device, comprise, sand extraction tube, is wrapped in the main body cover in sand extraction tube outside; Between described sand extraction tube and main body cover, be provided with screen pack; Described sand extraction tube is provided with venthole; Described main body cover is provided with air admission hole.
Wherein, described sand extraction tube is shaped as hollow circular-tube, and diameter is Ф 50mm-Ф 200mm, and length is 500mm-2500mm.
Wherein, described venthole is 1-200, bore dia: 4-20mm.
Wherein, described in carry sand pump main body cover, diameter is Ф 80mm-Ф 400mm, length is 100mm-600mm.
Wherein, described in to enter screen pack be cylindrical shape, diameter is Ф 60mm-Ф 210mm, length is 50mm-500mm, mesh is Ф 0.2mm-Ф 5mm.
Wherein, described air admission hole is 1-10, and bore dia is Ф 4mm-Ф 60mm.
Air Continuous Flow sand filter is carried a sand device, can be accurately continuous dirty sand is delivered to sand-washing device cleans, due to the acutely friction under compressed-air actuated effect of air, water, sand, the foreign material wash-out that sand is held back.Sand after cleaning adds in filter bed from top to bottom because of gravity, and washed-out sand water discharges by independent blow-off pipe, completes whole washed-out sand process, to reach optimum filtration effect.Maintenance management is simple, easy to operate, and maintenance rate is few, and operating cost is low.
Beneficial effect: the disclosed air Continuous Flow of the utility model sand filter is carried sand device, simple in structure, filtered wastewater that can be rapidly and efficiently, prevents that sand filter course from hardening.
