Abstract
The utility model discloses a high -efficient active sand filter, including the shell, the shell is inside to be equipped with the water -locator, this water -locator of water inlet lug connection, and the water -locator below is for leading the sand hopper, the inside end of shell is equipped with the air lift, and the long tube of being connected with the air lift runs through the water -locator and leads the sand hopper and stretches to the shell top, long tube top both sides are equipped with the washed -out sand ware, the top is equipped with collecting container, and the clear water in the collecting container passes through delivery port discharge shell, and collecting container connects and leads to the outer washed -out sand outlet of sewer of casing. The utility model discloses comparing with the conventional art, collecting flocculation, sediment, filtration treatment in an organic whole, simplified the flow that the traditional handicraft was handled, area is little, disposable investment is low, need not singly to establish facilities such as coagulating basin, depositing reservoir, need not equipment such as back flush pump and electronic, pneumatic valve etc..
Description
Technical field
The utility model belongs to sewage treatment area, is specifically related to a kind of high-efficiency activated sand filter.
Background technology
The succession running treatment facility that high-efficiency activated sand filter is a kind of Collecting flocculation, clarification, filtration and biological treatment function are integrated, is widely used in drinking water, water for industrial use, advanced treatment of wastewater and Treated sewage reusing process field.Active sand filter (also known as Continuous Flow sand filter) adopts up-flow thermopnore work principle of filter and single homogeneous filtering material; filter and carry out with washed-out sand simultaneously; can automatically run continuously for 24 hours; without the need to shutting down backwash; carry sand cleverly and washed-out sand structure instead of typical high power backwashing system, energy consumption is extremely low, Maintenance free; simple and convenient management, can unmanned.High-efficiency activated sand filter is based on countercurrent action, and pending former water enters filter interior by water inlet pipe, after the water-locator uniform distribution of bottom, flow through filter bed to superinverse, and the filtrate after filtration is overflow discharge filter system after filter top is collected.Under the effect of air compressor machine, contaminated for filter bottom dirty sand is promoted in the sand-washing device of filter top by air lift, the separated from contaminants on sand surface is gone out by the action of turbulent flow of current.Clean sand after cleaning utilizes deadweight to turn back in casting bed, and the sewage that cleaning sand produces is discharged from the sewage draining exit of filter.
Summary of the invention
Goal of the invention: the purpose of this utility model is for the deficiencies in the prior art, provides a kind of high-efficiency activated sand filter.
Technical scheme: in order to reach foregoing invention object, the utility model has specifically come like this: a kind of high-efficiency activated sand filter, comprise shell, enclosure is provided with water-locator, water inlet directly connects this water-locator, for leading sand hopper below water-locator, be provided with air lift at the bottom of described enclosure, the long tube be connected with air lift runs through water-locator and leads sand hopper and stretches to cover top portion; Both sides, long tube top are provided with sand-washing device, top is provided with collecting container, and the clear water in collecting container discharges shell by delivery port, and collecting container connects the washed-out sand outlet of sewer led to outside housing.
Beneficial effect: the utility model is compared with conventional art, and Collecting flocculation, precipitation, filtration treatment are in one, and simplify the flow process of traditional handicraft process, floor space is little; One-time investment is low, without the need to setting up the facility such as coagulating basin, depositing reservoir, without the need to equipment etc. such as backwashing pump and electronic, operated pneumatic valves.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
The high-efficiency activated sand filter of one as shown in Figure 1, comprise shell 1, shell 1 inside is provided with water-locator 2, water inlet 3 directly connects this water-locator 2, for leading sand hopper 4 below water-locator 2, described shell 1 inner bottom is provided with air lift 5, and the long tube 6 be connected with air lift 5 runs through water-locator 2 and leads sand hopper 4 and stretches to shell 1 top; Both sides, long tube 6 top are provided with sand-washing device 7, top is provided with collecting container 8, and the clear water in collecting container 8 discharges shell 1 by delivery port 9, and collecting container 8 connects the washed-out sand outlet of sewer 10 led to outside housing 1.
