The design of hydraulic screen, should be according to the size of water quality treatment, body refuse content, viscosity, a material thing, choose reasonable sieve seam gap, the oblique angle of sieve plate, the mode of scarfing cinder.At present there are some common problems using and design in hydraulic screen, as inhomogeneous in compass screen surface water distribution; Cannot remove fiber fines silk; Pulp water separates not thorough, occurs " metalling run out " phenomenon; Easily accumulated slag, and artificial scarfing cinder difficulty etc., increasing device cost on the one hand, does not reach the treatment effect of expection on the other hand.
Summary of the invention
For the problems referred to above, the purpose of this utility model is existing hydraulic screen to improve, the mechanical cleaning hydraulic screen decontamination apparatus that provides water distribution evenly, effectively to remove fiber fines silk, automatic slag removal.
For achieving the above object, the technical scheme that the utility model proposes is: a kind of mechanical cleaning hydraulic screen decontamination apparatus, comprise hydraulic screen body, and in described hydraulic screen body, be provided with successively fine fack, water distributing plate along water (flow) direction; It is characterized in that: also comprise the automatic slag removal district that is located at water distributing plate below, described automatic slag removal district comprises rotating filter screen cloth and is located at rotating filter screen cloth both sides makes rotating filter screen cloth make the transmission device rotating, and described both sides, rotating filter screen cloth below are provided for collecting the slag bucket of slag thing.
Preferably, described slag bucket top arranges rotating brush roll with rotating filter screen cloth adjacent.
Preferably, described transmission device comprises sprocket wheel and the adjustable frequency motor that is connected with sprocket wheel and sprocket wheel is done rotate, and described rotating filter screen cloth is located on sprocket wheel.
Preferably, described rotating filter screen cloth both sides arrange high pressure nozzle.
Preferably, described fine fack grizzly bar gap is 0.5~2.0mm.
Preferably, stainless steel swivel plate is established at described fine fack top, and stainless steel swivel plate and fine fack surface adjustable distance are 20~50mm.
Preferably, described water distributing plate is perforated plate, and aperture is 10~20mm, and via hole flow velocity is 0.3-0.5m/s.
Preferably, described rotating filter mesh size is 16~50 orders.
Preferably, described slag bucket volume is 0.5~1.0m 3.
Adopt technique scheme, mechanical cleaning hydraulic screen decontamination apparatus described in the utility model, the beneficial effect having is: by rotatable baffle plate, water distributing plate being set on fine fack top, reach the object of water distribution uniformity, sewage is after fine fack, rotating filter screen cloth simultaneously, dirt is by effectively catching, and adopts high pressure nozzle and rotating hairbrush that dirt is rinsed to slag bucket, reaches the object of mechanical deslagging; Overcome hydraulic screen water distribution inequality traditional, except shortcomings such as fiber fines poor effect, artificial deslagging difficulties, can be used for the pretreatment of the meticulous equipment such as hollow-fiber membrane bioreactor.
