Description
Technical field
It the utility model is related to sewage-treatment plant, more particularly to a kind of double case gravity valveless filters.
Background technology
Valveless water filter device is widely used in earth's surface Water warfare, and recirculated water bypath filter, production waste water removes suspended impurity, organic
Filtering of the sewage after biochemical and two heavy processing.Steel valveless water filter device is mainly periodically backwashed using siphon principle, mistake
Filter water inlet water outlet, flushing and draining do not have to valve, by hydraulic action automatic running.Operation principle：Raw water by water pipe into
Enter filter tank by the top-down filtering of filtering layer, afterwards into water tank, clear water reserviors are entered by outlet pipe after being full of.Filtering layer constantly stays
Suspended matter, causes resistance to increase, and promotes the water level in siphon pipe constantly to raise, when water level reaches the auxiliary siphon tube mouth of pipe,
Water is fallen from the pipe, and the air declined by exhaust tube so as to taking away siphon, when vacuum reaches certain value, just occurs siphon
Act on and water is backwashed from bottom to top by filtering layer to filtrate.When the flush box water surface drops to siphon destructing tube,
Air enters siphon pipe, destroys siphonage, and backwash terminates, and filtering restarts.
What the filtering of sewage was leaned on is the filtering layer in packing layer, and general filtering layer that can not be in filter in packing layer is to be connected in
Together, one layer is connect for one layer, sewage successively completes filtering after filtering layer；Such a mode has a defect that sewage can not be equal
The even filtering layer with packing layer contacts, and since the flow velocity of sewage is too fast, the effect for influencing filtering can not be come into full contact with filtering layer.
Utility model content
The technical problems to be solved in the utility model is uniform, the filtering that overcomes the deficiencies of the prior art and provide a kind of water distribution
Effect is good, a kind of good double case gravity valveless filters of backwash effect.
To realize that the utility model provides following technical scheme：A kind of double case gravity valveless filters, including it is symmetrical
The water tank of setting, the tank top top are equipped with shared high water tank, and bottom front is equipped with shared siphon sink, described
High water tank bottom is equipped with water inlet, and the water tank is divided into filtered water tank, water tank with strainer and back flushing tank successively from top to bottom, clearly
Communicating pipe is equipped between water tank and back flushing tank, the filtered water tank side wall upper part is equipped with water outlet, siphon pipe is equipped with filtered water tank,
Back flushing tank is stretched into described siphon pipe one end, and the other end stretches into siphon sink；Packing layer, packing layer are equipped with the water tank with strainer
Lower section is equipped with water filtering cap, is equipped with some filter material layers in described filler layer, water distributing plate, the cloth are equipped between filter material layer and filter material layer
Water plate is equipped with latticed through hole, and through hole is surrounded by radial drainage trough, water distributing plate also is provided with the top of described filler layer, described
Buckle-type connects between water distributing plate and filter material layer.
Preferably, the water tank with strainer and back flushing tank side wall are equipped with access hole.
Preferably, described filler layer filling height is 900 ~ 1000mm.
Preferably, the tank inner wall coating coal tar pitch anticorrosive paint.
The usefulness of the utility model：Water distributing plate is set between filter material layer, and sewage can enter each layer of filtrate
When all water distribution uniformity and slow down the time of contact that flow velocity extends sewage current and filtrate, preferably complete filtering, use buckle-type
Connection mode, easy access unpicks and washes；At the same time in backwash, due to being all provided with water distributing plate between every layer, to every layer
The cleaning of filtrate is more thorough.
