Description
Technical field
The utility model belongs to technical field of water treatment equipment, and in particular to a kind of active sand filter.
Background technology
High-efficiency activated sand filter is the continous way fortune that a kind of Collecting flocculation, clarification, filtering and biological treatment function are integrated
Row processing equipment, is widely used in drinking water, industrial water, advanced treatment of wastewater and Treated sewage reusing process field.Active sand mistake
Filter (also known as continuous shifting sand filter) uses up-flow thermopnore work principle of filter and single homogeneous filtering material, and filtering is with washed-out sand simultaneously
Carry out, can 24 hours continuous automatic runnings, backwashed without shutting down, cleverly carry sand and washed-out sand structure instead of traditional big work(
Rate backwashing system, energy consumption is extremely low, Maintenance free, and management is easy, can be unattended.But existing filtration device structure is single,
It is difficult to meet actually used needs.
Utility model content
The purpose of this utility model is to provide a kind of active sand filter.
To achieve these goals, the utility model is adopted the following technical scheme that：
A kind of active sand filter, including filter holder, filter holder are provided with filter body, the filter
Body includes housing, and the outside of housing is provided with least two symmetrical links, housing upper be provided with filthy water outlet, original water inlet and
Filtrate (liquid, the bottom of housing is provided with filter sand outlet, and enclosure interior center is provided with dirty sand riser, the lower end of dirty sand riser
Connection air lift, the top both sides of dirty sand riser are provided with sand-washing device, and the upper end of dirty sand riser is provided with water collector, catchments
Device upper end is provided with the splash cap connected with water collector, water collector connection filthy water outlet；The periphery of dirty sand riser, in housing
Portion is provided with the water-locator being connected with original water inlet, and the periphery of the dirty sand riser of the lower end of water-locator is provided with filter sand guider；
The dirty sand riser is followed successively by corundum ceramic, transition zone and steel from inside to outside.
Preferably, dirty sand riser is, using the dirty sand riser being made from climing combustion high temperature clutch synthetic method, to solve work
Property sand filter in dirty sand riser be made up of glass reinforced plastic pipe, connection place must manual pasting, complex manufacturing technology obtains problem,
The excitant taste for solving the resin in manufacturing process simultaneously is difficult to stand, and dust when polishing, cutting is to environment and workman
It is healthy unfavorable, resin is inflammable, and the problem of larger threat is there is also to safety；The corundum ceramic be 2200 DEG C with
On temperature under the corundum ceramic that obtains；The transition zone technology known to those skilled in the art, therefore here is omitted.
The utility model has advantages below using ceramic composite pipe：
1st, wearability is good, and ceramic composite pipe is corundum ceramic (a-AL due to inner liner2O3), Mohs' hardness is suitable up to 9.0
In more than HRC90.Therefore the grindability medium for being conveyed to industries such as metallurgy, electric power, mine, coals is respectively provided with high-wearing feature.
Confirmed through industry park plan：Its friction durability is ten times even tens times of hardened steel.
2nd, running resistance is small, ceramic composite pipe because inner surface is smooth and never corrosion, also not as seamless steel pipe interior surface
With the presence of convex helix.Tested through relevant detection unit inner surface roughness and clear water drag characteristic, its inner surface is smooth
Degree is better than any metallic conduit, and clear resistance coefficient is 0.0193, more slightly lower than seamless pipe.Therefore the pipe has the small grade of running resistance special
Point, can reduce operating cost.
3rd, corrosion-resistant, good antiscale property, because the steel ceramic layer is (a-AL2O3), the neutral speciality of category.Therefore have acid and alkali-resistance and
Seawater corrosion resistance, and there is the characteristics such as antiscale simultaneously.
4th, ceramic composite pipe is lightweight, affordable.More lightweight than the glass-ceramic tubre of same internal diameter 50%；Than wear-resisting alloy pipe weight
Light 20-30% is measured, and wear-resisting, corrosion resistance is good, because long service life, so that suspension and support expense, portage, installation fee and fortune
The reduction of row expense.Through relevant designing institute and unit in charge of construction's construction budget and engineering is actual compares, the pipe construction costs and cast stone phase
When, compared with wear-resisting alloy pipe, construction costs declines 20% or so, while installation is convenient, because the pipe is lightweight, and weldering
Connect performance good.Therefore can be using modes such as welding, flange, quick-jointings, construction and installation are convenient, and can reduce mounting cost.
Compared with conventional art, Collecting flocculation, precipitation, filtration treatment are simplified at traditional handicraft the utility model in one
The flow of reason, simple structure, floor space is small.In the process of running without any rotatable parts, fault rate be low, maintenance cost is low,
It does not need the facilities such as flocculation basin, depositing reservoir, and filter utilization rate is high, and one-time investment is low, and filtrate cleaning is timely, it is ensured that steady
Fixed, good filtration effect.
