Description of the drawings
Fig. 1 is structural representation of the present utility model.
Specific embodiment
This utility model is further illustrated with embodiment in conjunction with description of the drawings：
With reference to Fig. 1, a kind of active sand continuous filter, wherein：Including housing 1, have inside housing 1 raw water filtration device and
Filtering material cleaning device 2；Raw water filtration device and filtering material cleaning device are electrically connected with the switch board of hull outside；Switch board by
PLC, display lamp and operation button composition.
Raw water filtration device has the ring sparger 4 and case top that are installed on housing bottom to be provided with excessive weir flow structure；Excessive weir flow
Structure is arch exit weir 3.
Ring sparger 4 is connected with filter bed, and guiding gutter and conical distributor are provided with filter bed；Ring sparger is connected with elevator pump.
Filtering material cleaning device 2 has the compressed air sand extraction device 21 for being located at 1 bottom of housing, the three-phase for being arranged on case top
Separator and wash husky device；Three-phase is empty gas and water and sand, and compressed air sand extraction device 21 is connected with three phase separator by sand developing tube
Connect；Three phase separator respectively with wash husky device and exhaustor is connected；Filter bed is connected with agitator 5；Washing husky device has water inlet, anti-cleaning
Unit and sewage outlet 22, sand-washing device are provided with sand developing tube and stretch into housing bottom for carrying sand, and the interior middle part of sand developing tube is provided with spiral and carries
Sand shocking rod 23, compressed air sand extraction device 5 are arranged in housing 1 and carry sand plate, and carrying sand plate is free air cavity, and air cavity leads to
Cross air line to be connected with air pressure pump.
Operation principle：
Efficiently the operation of shifting sand filter can be divided into raw water filtration and filtrate cleaning and regeneration two is relatively independent and while enter
Capable process.The two is completed in the diverse location of same filter, and the former power relies on the lifting of high potential difference or pump, and the latter is then
Completed by compressed air.
1. raw water filtration：
When raw water is pumped into the ring sparger of filter bottom, Jing guiding gutters and conical distributor by head tank gravity flow or elevator pump
Uniform impurity upwards gradually countercurrently in filter bed, raw water is by constantly retention, absorption, final filtrate overflowing from filter top
Weir flow is discharged, and completes filter process.
2. filtrate cleaning and regeneration：
When filter constantly carry out when, filter material surface is also constantly accumulated and be trapped in the impurity in raw water, and holding filth capacity
Maximum is the filtrate of bottom.This part filtrate is passed through special material by compressed air sand extraction device first that be located at filter bottom
The sand developing tube of matter is quantitatively submitted in batches to the three-phase at top（Water, gas and sand）In separator, air is discharged, and water and sand enter back into phase
Clean in sand-washing device even, by single discharge of pipes, the sand of wash clean is scattered and is distributed to whole filter bed table washed-out sand water again
Face, now oscillator starting can cause the sand in filter bed to be uniformly distributed, the cleaning for realizing filtrate and the process for circulating,
Spiral shocking rod in sand developing tube contributes to putting forward sand function simultaneously.
This utility model can substitute traditional fixed bed filtering system, can be applicable to Water purification, wastewater treatment, waste water
Advanced treating and Treatment for Reuse.The filter adopts up-flow thermopnore work principle of filter and single homogeneous filtering material, filters and washed-out sand
Simultaneously carry out, can 24 hours continuous automatic runnings, backwash need not be shut down, sand is cleverly carried and washed-out sand structure be instead of tradition
High-power backwashing system, energy consumption are extremely low.System Maintenance free and keep an eye on, management is easy.
In sum, after one of ordinary skill in the art reads this utility model file, according to skill of the present utility model
Art scheme and technology design make other various corresponding conversion schemes without the need for creative mental work, belong to this practicality new
The scope protected by type.
