Abstract
The invention provides a filter media loss-free continuous drift sand filter, which comprises an air lift pump and a sand washer, and is characterized in that the upper end of the air lift pump is provided with a reflection sand control cover; the reflection sand control cover is fixedly connected with the sand washer. Further, the upper end of the reflection sand control cover is closed, and the lower end of the reflection sand control cover is open; the reflection sand control cover consists of a reflection sand control cover inner barrel and a reflection sand control cover jacket; the reflection sand control cover inner barrel is arranged in the reflection sand control cover jacket; the diameter of the reflection sand control cover jacket is greater than that of the reflection sand control cover inner barrel; the side wall of the reflection sand control cover inner barrel is provided with air vents; and the reflection sand control cover jacket covers the air vents. The filter media loss-free continuous drift sand filter provided by the invention has the beneficial effects that the reflection direction of filter media drift sand discharged along with gas is changed through the reflection sand control cover, so that filter media cannot run off any longer along with the discharged gas, the quartz sand filter media can be recycled for a long term, and thereby, the environmental pollution is reduced while natural resources are saved. Meanwhile, the quality of filtered water can be better ensured to be good and stable by the quartz sand filter media with constant thickness.
Description
Technical field
The invention belongs to technical field of sewage treatment equipment, be specifically related to a kind of by change the quicksand reflection direction reach without filtrate run off without filtrate loss Continuous Flow sand filter.
Background technology
The Continuous Flow sand filter is called for short sand filtration apparatus, is that the municipal sewage plant carries out the important sewage disposal device that advanced treatment of wastewater reaches country-level A discharge standard.Filled quartz sand in the sand filtration apparatus and be used for filtering sewage, quartz sand is called for short again filtrate.Sand filtration apparatus makes filtrate circulation based on the air lift principle, and gas lift upwards is pushed to the upper end of airlift pump with the mixture of the dirty sand of bottom, husky pond and water by central tube, and the steam vent of the current stabilization cover of gas by being arranged on the airlift pump upper end is discharged.The sand steam vent of carrying of sand filtration apparatus all is to design vertically upward on the top of current stabilization cover both at home and abroad at present, gas can carry filtrate when the steam vent on current stabilization cover top is discharged, filtrate falls into again the pond during normal operation under Action of Gravity Field, but need strengthen during device start in the unsettled situation of gas pressure and flow and system pressure, a small amount of filtrate will follow the gas of discharge to gush to sand filter from the exhaust outlet that makes progress, and causes filtrate constantly to run off.Therefore not only cause the filtrate waste, also can produce and effectively filter the thickness of filter bed minimizing in the pond, and then cause effluent quality not up to standard.
Summary of the invention
For solving existing sand filtration apparatus design principle defective in the field and not enough filtrate loss and the filtered water water quality problem not up to standard that causes, the invention provides a kind of without filtrate loss Continuous Flow sand filter, this filter is by design reflectivity control sand cover, change is with the reflection direction of the filtrate quicksand of gas discharge, run off thereby reach without filtrate, saved natural resources, reduced pollution, guaranteed that filtered water water quality is good.
The present invention specifically is achieved through the following technical solutions:
Without filtrate loss Continuous Flow sand filter, comprise airlift pump 1 and sand-washing device 2, it is characterized in that: described airlift pump 1 upper end arranges reflection control sand cover 3, and reflection control sand cover 3 is fixedly connected with sand-washing device 2.
Described reflection control sand cover 3 upper end closed lower ending openings, consisted of by reflection control sand cover inner core 4 and reflection control sand outer sleeve 5, the reflection control sand outer sleeve 5 interior reflection control sand cover inner cores 4 that arrange, reflection control sand outer sleeve 5 diameters are greater than reflection control sand cover inner core 4, be provided with steam vent 6 on reflection control sand cover inner core 4 sidewalls, reflection control sand outer sleeve 5 covers steam vent 6.
Described steam vent 6 is distributed on the sidewall of reflection control sand cover inner core 4 at 40-60mm place, top of distance reflection control sand cover 3.
Described reflection control sand cover 3 is made by high density polyethylene (HDPE) or stainless steel.
Beneficial effect of the present invention: the present invention changes the reflection direction of the filtrate quicksand of discharging with gas by reflection control sand cover, filtrate is no longer run off with Exhaust Gas, can make quartz sand filter media recycling for a long time, can save so a large amount of natural resources and reduce again pollution to environment, reduce simultaneously the operating cost of equipment, improved the market competitiveness.Simultaneously, the quartz sand filter media that thickness is constant has also better guaranteed the good stable of filtered water water quality.
Description of drawings
Fig. 1 is structural representation of the present invention;
The specific embodiment
The present invention is further described below in conjunction with accompanying drawing.
Without filtrate loss Continuous Flow sand filter, comprise airlift pump 1 and sand-washing device 2, it is characterized in that: described airlift pump 1 upper end arranges reflection control sand cover 3, and reflection control sand cover 3 is fixedly connected with sand-washing device 2.
Described reflection control sand cover 3 upper end closed lower ending openings, consisted of by reflection control sand cover inner core 4 and reflection control sand outer sleeve 5, the reflection control sand outer sleeve 5 interior reflection control sand cover inner cores 4 that arrange, reflection control sand outer sleeve 5 diameters are greater than reflection control sand cover inner core 4, be provided with steam vent 6 on reflection control sand cover inner core 4 sidewalls, reflection control sand outer sleeve 5 covers steam vent 6.
Described steam vent 6 is distributed on the sidewall of reflection control sand cover inner core 4 at 40-60mm place, top of distance reflection control sand cover 3.
Described reflection control sand cover 3 is made by high density polyethylene (HDPE) or stainless steel.
For further technical scheme of the present invention being described, its concrete steps are as follows: according to the suitable reflection control sand cover of amount of capacity design without filtrate loss Continuous Flow sand filter, dig steam vent at reflection control sand cover inner core sidewall, passage as airlift pump discharge water gas mixture, simultaneously, carry filtrate in the discharge water gas mixture.In the periphery of reflection control sand cover inner core steam vent reflection control sand outer sleeve is set, reflection control sand outer sleeve block water gas mixture laterally splashes, and the guiding gas-vapor mix moves downward, thereby makes filtrate all fall into casting bed in the pond and can not gush and run off to sand filter.
In addition, the present invention and not meaning that by schematic diagram and specification limits to.The remodeling that those skilled in the art do the present invention under the prerequisite that does not break away from design aim of the present invention and principle thereof, variation, interpolation all belong to protection domain of the present invention.
