Description
Technical field
The invention belongs to water treatment filtering equipment, is a kind of circulation filtering layer filter, is applicable to the particulate matter such as various suspensions, colloid in filtering water.
Background technology
The filter material layer of existing water treatment filtering equipment is all stacked or is fixed in the pond body in filter tank, as quartz sand, fibrous nodules, comet fiber filter, fibre bundle and filter cloth etc.Its technical process is: the cyclic process of filtration → filtering layer cleaning → filtration.Mainly there is following problem in existing filter plant, 1. stacked the filtering layer formed intensity can not be excessive when cleaning by loose filtrate, otherwise random layer, race material can occur, so cleaning performance is poor; 2. filtering layer filters and reaches capacity and need cleaning and regeneration, and equipment can not continuous operation; 3. the thickness of filtering layer determines retaining power and filtering accuracy, and filtering layer its loss of flood peak thicker is larger, and the height of equipment is higher, filtering layer cross its retaining power thin and filtering accuracy lower; 4 when the turbidity of former water is more than 50NTU, and filtering layer will lose efficacy in a short period of time; 5. the water quality of filtering must be through the water after coagulation, precipitation process; 6. can not be used for the filtration containing sewage such as mud, algae, sandstones.
Summary of the invention
The object of this invention is to provide a kind of circulation filtering layer filter, it is rational in infrastructure, circulation filter material layer is that closed loop filters broadband, remain mobile status in filtration and cleaning process always, translational speed can adjust according to raw water turbidity, ensure that filtering layer is no more than the retaining power of filtering layer at the dirt that filtration zone retains, filtration flow-rate by suspension content in former water number affect, drastically increase the retaining power of filter plant, ensure that and filter the stable of effluent quality, be specially adapted to containing a large amount of suspension, the filtration of colloidal impurity ultra, also the process of different quality can be adapted to by changing filtering layer material, the sandstone carried secretly in water as former in filtering, algae, the impurity such as scum and mud, also can be used to other solid impurity contained in filtered water, circulation filter material layer also has long service life, change advantage easily.
The object of the invention is to be realized by following technical scheme: a kind of circulation filtering layer filter, it is characterized in that, it comprises housing, be provided with distribution reservoir on the top of housing, the front portion of distribution reservoir is provided with front tank, is provided with the guiding gutter be communicated with front tank in distribution reservoir, front tank is connected with raw water tubes by inlet valve, the bottom of distribution reservoir has water distribution orifice plate, and the upper end of seal closure is fixed on water distribution orifice plate lower surface, and the lower end of seal closure contacts with the upper strata of circulation filtering layer; The two side of housing arranges a driving shaft in rectangular layout and three driven axles respectively by bearing block, and driving shaft and power set are connected, and are all fixed with drive sprocket at the two ends of driving shaft, and the two ends of driven axle are all fixed with by movable sprocket; Circulation filtering layer is fixed on the outer ring of holder chain, and the solderless wrapped connection of holder chain filters broadband at the drive sprocket of both ends of main drive shaft and the closed loop that movable sprocket is formed at driven axle two ends, and the upper strata of circulation filtering layer, above Rinsing Area collecting-tank, is placed in rinse water pond under it; Be provided with service sink in the bottom of housing, service sink is connected with cleaning discharge pipe line, blow-off pipe by the osculum on sidewall, and cleaning discharge pipe line is provided with cleaning water discharging valve; Clear water collecting-tank is fixed in housing, and circulation filtering layer is looped around the surrounding of clear water collecting-tank, and clear water collecting-tank is connected with Graceful water pipe by the osculum on sidewall; Be provided with several cleaning shower nozzles in the bottom of clear water collecting-tank, cleaning shower nozzle is connected with flushing water pump and clear water house steward by detergent line.
Spray-hole on cleaning shower nozzle is towards the inner surface of filter material layer.
Circulation filtering layer is filter cloth, metallized metal silk screen, nonmetal silk screen or short fiber bundle.
The nip drum contacted with the upper strata of circulation filtering layer is had at housing hinge.
The advantage applies of circulation filtering layer filter of the present invention exists:
1. owing to being respectively equipped with filtration and cleaning area, circulation filtering layer remains motion state in the process of filtering and clean always, circulation filtering layer is that closed loop filters broadband, intake pool is provided with on the top on the upper strata of circulation filtering layer, thereon, lower floor middle part is provided with clear water collecting-tank, the bottom of lower floor is provided with service sink, during work, circulation filtering layer is round the discharge bay shuttling movement of centre, the filtering layer of circulation filtering layer moves horizontally, current flow in clear water reserviors through the filtering layer of movement through guiding gutter vertically downward, solid impurity in water is dammed in filtering layer, the filtering layer being loaded with dirt moves to cleaning area from filtration zone and cleans, move to again filtration zone after cleaning up to filter, so just complete filtration simultaneously, the technical process of cleaning,
2. circulation filtering layer translational speed can adjust according to raw water turbidity, raw water turbidity height circulation filtering layer translational speed is fast, ensure that the dirt retained at filtration zone is no more than the retaining power of filtering layer, due to this adjustable function, thus ensure that filtration flow-rate not by the impact that the suspension in former water is how many, therefore drastically increasing the retaining power of filtering layer, ensure that the effluent quality when filtering ultra;
3. filter material layer long service life, and change conveniently, the suspension in filtering ultra, colloidal impurity can be widely used in; Also can be used to other solid impurity contained in filtered water.
