Abstract
The utility model discloses a compound backpurge system's of spiral pulse air water water -locator structure of intaking, including inclosed filtering ponds that link to each other with the sedimentation tank, the bottom of filtering ponds is equipped with clear water output pipeline, the top of filtering ponds is equipped with the inlet tube, the inside upside of filtering ponds is equipped with the water -locator of evenly arranging, be equipped with the filter screen that prevents filtering medium and rush out in the water -locator, the import of water -locator links to each other with a water knockout drum outside extending to the filtering ponds top, the water knockout drum links to each other with the inlet tube again, be equipped with a blow off pipe between inlet tube and the water knockout drum, all be equipped with an automatic control's electric valve on inlet tube and the blow off pipe, the utility model discloses guaranteeing that rivers that the inlet tube got into get into the top of filtering ponds more gently behind water knockout drum and water -locator uniform distribution, reducing the water column and wash away filtering medium, do benefit to the system of filtering water more, during the blow off pipe can be be fast arranged through water -locator and water knockout drum to back flush sewage, it is marginal that sewage can not overstock filtering ponds inside.
Description
Technical field
The utility model relates to water treatment plant's production technical field, particularly relates to a kind of water inlet distributor structure of spiral pulse air water compound backwashing system.
Background technology
Along with the progressively enforcement of rural drinking water safety projects, small towns, other water treatment plant at village level application get more and more, and the water treatment plant of this type requires to utilize rural surface water to process as far as possible, and water purification facilities cost as far as possible rationally, operation and maintenance cost is low, uses to be applicable to rural area.
When using surface water to carry out purified treatment, enter filtering ponds through the pretreated former water of sedimentation basin to filter, need to carry out backwash to the filter medium in filtering ponds after filtering a period of time, the impurity be mixed in filter medium is discharged, make the filter capacity that filter medium recovers excellent, backwash of the prior art is generally adopt the jet pipe be located at bottom filtering ponds to spray a large amount of water the filter medium entirety in filtering ponds is washed away picking-up, filter medium is made to roll to discharge the impurity in filter medium in filtering ponds, the impurity of discharging in filter medium is blended in backwashing water, backwashing water after dirt is discharged by the blow-off pipe that filtering ponds top water inlet connects, all only single water inlet is set at filtering ponds crown center because prior art is general, this structure filter medium of filtering ponds inside when intaking easily is subject to single water column and washes away generation disturbance, wash away place's filter medium to reduce, make filtration water deleterious, and during backwash draining, sewage easily overstocks in filtering ponds internal edge, more difficult quick discharge, requires further improvement.
Summary of the invention
For overcoming the deficiencies in the prior art, the utility model provides a kind of filter medium not easily disturbance when filtering water processed of intaking, the water inlet distributor structure that during backwash, blowdown is smooth and easy, sewage not easily overstocks the spiral pulse air water compound backwashing system at filtering ponds internal edge.
The utility model for the technical scheme reaching above-mentioned technical purpose and adopt is: a kind of water inlet distributor structure of spiral pulse air water compound backwashing system, comprise the airtight filtering ponds be connected with sedimentation basin, the bottom of described filtering ponds is provided with the clear water output channel connecting clear water reserviors, the top of described filtering ponds is provided with the water inlet pipe be connected with sedimentation basin high position delivery port, the upper inside of described filtering ponds is provided with the water-locator be evenly arranged, described water-locator circumferentially array is arranged, the screen pack preventing filter medium to be rushed out is provided with in described water-locator, the import of described water-locator extends to outside described filtering ponds top, described filtering ponds top is provided with a water knockout drum and is connected with the import of described water-locator, described water knockout drum is connected with water inlet pipe again, a blow-off pipe is provided with between described water inlet pipe and water knockout drum, described water inlet pipe and blow-off pipe are all provided with an electrically operated valve automatically controlled.
Described water-locator outlet is provided with the water distribution mouth of a bell mouth shape.
Described water-locator is four or eight.
The beneficial effects of the utility model are: after adopting said structure, by arranging the water-locator be evenly arranged at the top of filtering ponds, the screen pack preventing filter medium to be rushed out is provided with in water-locator, the water knockout drum that water-locator is arranged with filtering ponds top is again connected, water knockout drum is connected with water inlet pipe again, the current that water inlet pipe is entered enter the top of filtering ponds more gently after water knockout drum and water-locator uniform distribution, reduce water column and wash away filter medium, filter medium not easily produces disturbance and is more beneficial to filtration water processed, during backwash draining, sewage can be discharged in blow-off pipe quickly through water-locator and water knockout drum, sewage can not overstock filtering ponds internal edge, filter medium backwash speed can be accelerated.
