Abstract
The utility model discloses a self-cleaning active sand filtering basin, relates to a water treatment filtering device, and particularly relates to a water filtration treatment device having an automatic quartz sand filtering material cleaning function and mainly used for removing the suspended matters and colloids in sewage and other partial impurities without shutdown for back washing. The self-cleaning active sand filtering basin comprises a circular or a square basin body, and a water inlet, a water outlet pipe and a sewage outlet which are connected with the basin body, wherein quartz sand, a quartz sand filling area, a bottom support, a sand lifting device, a sand washing device, a water drain adjusting device and a sewage discharge adjusting device are arranged in the basin body. The self-cleaning active sand filtering basin has the characteristics of continuous filtering, simple structure, convenience in maintenance, even back washing, low water consumption, high cleanliness of quartz sand, no hardening and long service life (more than 20 years).
Description
Technical field
The utility model relates to a kind of water treatment facilities, is specially a kind of self-cleaning active sand filtering ponds.
Background technology
At present; filtering ponds take quartz sand as filtering material are widely used in filtering technique in water treatment; have advantages of that selection is extensive, outlet effect good, floor space is little; but also ubiquity need to be shut down backwash, equipment investment is large, quartz sand hardens, service life is short; a kind of novel flowing sand filter has appearred this year; but when the flowing sand filter that uses now filters, water distribution is inhomogeneous; effluent quality is undesirable; quartz sand hardens commonplace; the recoil water consumption is high, and quartz sand is changed frequent.
The utility model content
The technical problems to be solved in the utility model is to provide a kind of water treatment facilities of new structure, is self-cleaning active sand filtering ponds, solves existing quartz sand filter tank (device) complex structure, safeguard loaded down with trivial details, the recoil water consumption is large, and quartz sand often hardens, the problem that service life is short.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is to provide a kind of self-cleaning active sand filtering ponds, for addressing the above problem, the utility model adopts following technical scheme: comprising is connected with circular or square pond body (1) is connected to water inlet (2), delivery port (3), sewage draining exit (4); Be provided with quartz sand filling area (10), bottom support (5) in the body of pond, carry sand device (6), sand-washing device (7) and Water outlet adjusting device (8) and blowdown adjusting device (9).
Carry sand device (6) and sand-washing device (7) and supported by bottom support (5), bottom support (5) is connected bottom the body of pond; Sand-washing device (7) comprises the three phase separator that is positioned at the sand developing tube periphery, the washed-out sand mud discharging mouth, and the water level adjustable plate, sand developing tube is comprised of urceolus and inner core, and inside is set to the corrugated labyrinth passage, and the sand-washing device urceolus is stainless steel or glass steel material; Water outlet adjusting device (8) and blowdown adjusting device (9) are carbon steel, stainless steel or composite, are provided with the strip hole on adjustable plate.
The utility model has the advantage of: be continuous filtration and online backwashing during work, simple in structure, easy to maintenance, the backwash cleanliness is high and water consumption is low, and quartz sand does not harden, and service life is more than 20 years.
Description of drawings
Fig. 1 is the utility model self-cleaning active sand filtering ponds structural representations.
Symbol description in figure: pond body (1), water inlet (2), delivery port (3), sewage draining exit (4), bottom support (5), carry sand device (6), sand-washing device (7), Water outlet adjusting device (8), blowdown adjusting device (9), quartz sand filling area (10).
The specific embodiment
The below is described in detail the utility model with best embodiment.
As shown in Figure 1, as shown in Figure 1, this device comprises: comprising is connected with circular or square pond body (1) is connected to water inlet (2), delivery port (3), sewage draining exit (4); Be provided with quartz sand filling area (10), bottom support (5) in the body of pond, carry sand device (6), sand-washing device (7) and Water outlet adjusting device (8) and blowdown adjusting device (9).
Carry sand device (6) and sand-washing device (7) and supported by bottom support (5), bottom support (5) is connected bottom the body of pond; Sand-washing device (7) comprises the three phase separator that is positioned at the sand developing tube periphery, the washed-out sand mud discharging mouth, and the water level adjustable plate, sand developing tube is comprised of urceolus and inner core, and inside is set to the corrugated labyrinth passage, and the sand-washing device urceolus is stainless steel or glass steel material; Water outlet adjusting device (8) and blowdown adjusting device (9) are carbon steel, stainless steel or composite, are provided with the strip hole on adjustable plate.
Above part is all assembled formation except pond body (1), and the pond body can be steel construction or concrete, if steel construction is also assembled formation.
Self-cleaning active sand filtering ponds are the reaction of a kind of Collecting flocculation, clarification, filter and the water treatment treating apparatus of the online backwash of succession running that the biological treatment function is integrated, and are widely used in drinking water, water for industrial use, advanced treatment of wastewater and middle water Treatment for Reuse field.This device adopts up-flow thermopnore work principle of filter and single homogeneous filtering material; filter with washed-out sand and carry out simultaneously; can automatically move continuously in 24 hours; need not to shut down backwash; put forward cleverly sand and washed-out sand structure and replaced traditional high-power backwashing system, energy consumption is extremely low, Maintenance free; simple and convenient management, but unmanned.
its operation principle is based on adverse current work principle of filter and the water online backwashing that utilizes after filtering, former water is by water inlet access to plant quartz sand bottom from top to bottom, water flows in quartz sand from bottom to top, most suspended substances and colloid and other partial impurities in the quartz sand bottom by filtering, a small amount of impurity is in quartz sand top filtration, water after filtration Water outlet adjusting device after filtration flows into delivery port, complete clean water treatment, because quartz sand has been held back many impurity when filtering, need backwash could realize reusing, simultaneously held back most of impurity because of water in the quartz sand bottom, so need first clean the quartz sand of bottom, dirty sand under the effect of carrying the sand device constantly quartz sand that the bottom is dirty import and carry sand device bottom, rise to from bottom to top dirty quartz sand in sand-washing device by carrying sand pump, clear water after dirty quartz sand and filtration is in the sand-washing device swirl washing, because of the proportion of quartz sand heavier than water, washed-out sand device after filtration flows from bottom to top quartz sand is cleaned, quartz sand falls into the quartz sand filling area from top to down.
It should be noted that at last: obviously, above-mentioned enforcement is only for the utility model example clearly is described, and is not the restriction to embodiment.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here need not also can't give all embodiments exhaustive.And the apparent variation of being amplified out thus or change still are among protection domain of the present utility model.
