Description
Technical field
The utility model is the improvement of sewage disposal interception suspended substance and the small suspended particle of removal, fiber-like being blocked to dirty equipment fine fack.Relate to a kind of sewage disinfection treatment dirt removal device for fine grid in particular.
Background technology
Generally some suspended impurities are all contained in sewage, before sewage disposal, it need be separated from water, organic and inorganic suspended solids in degradation of sewage, for sewage advanced treatment and prevent the blocking of plumbing arrangements from guaranteeing standard water discharge provides indispensable pre-processing device.
The employing rotary type grid sewage-removing machine such as Chinese patent that prior art fine fack is more: CN102398948A, the described structure such as CN103145205A, this kind of grid adopts the rake teeth gathered, turning motion is done around two central shafts, slag is salvaged from the sewage of water channel in grid front to come up, fallen into hopper box when the reverse side slag moving to grids top relies on gravity or scraper plate to rotate, reached solid-liquid separation.The deficiency of this kind of grid sewage-removing machine there is suspension rubbish after rotary type grid sewage-removing machine, resemble plastics bag especially, the existence of the fiber rubbish such as knitting wool, and these things enter in next procedure and just can produce serious consequence, pipeline valves are caused to block, water pump agitator damages, and more serious meeting causes the paralysis etc. of whole water factory.Analyze reason, because rake teeth is with hook-shaped crown, a lot of wire, Plastic etc. hooked after, just be difficult to or gravity can not be leaned at all or turn brushing fall, and turn sewer main with rake teeth, carry water (flow) direction and just in time washed away by sewage and bring in next procedure, the object that solid-liquid is thoroughly separated can not be reached.Gap between the rake teeth of secondly general fine fack is about 5mm, and the structure due to itself determines can not be tackled for less suspended particle, can pass through from rake teeth gap, thus reduces the filtering accuracy that fine fack has.
Require high for filtering accuracy, the employing Barrate type grilling dirt remover that prior art fine fack is more, as Chinese patent CN202427238U, described this kind of grid such as ZL200920109800.1 drives the rotation of filtering net cylinder by a step-down gear, realize dragging for the conveying of slag and slag and the equipment of squeezing one function, solve with top slewing grid sewage-removing machine Problems existing.But also come with some shortcomings in actual use: one is the setting angle that this equipment and horizontal channel have about 35 °, filtering net cylinder and flowing water horizontal plane is so just made also to there is this angle, so the not enough whole net cylinder area of the actual filtration area of filtering net cylinder 1/3, effective filtration area reduces, and the large or increase number of devices that is net cylinder does could meet the requirement of water amount.Secondly because whole net cylinder is embedded in channel bottom and the indwelling of lower rotation bearing in sewage, rolling bearing is because long period of soaking is in sewage under water, in appearance corrosion with there will be stuck when lubricating unfavorable, causes whole equipment not run well.Dirt for fiber-like easily hangs upside down on mesh, the easy conjunctiva of long-time running filtering net face, though there is the flushing of pressure spray equipment, filtering wire side can not be clean by cleaning down, so the maintenance of general artificial removing and under water bearing is can hardly be avoided, due to this equipment be installed on sewage trench bottom artificial under in irrigation canals and ditches cleaning safeguard quite difficulty and there is danger, if do not retain sewage or this equipment of slinging for changing bearing and check lubrication just possibility under water.
Chinese patent CN102527133B dirt removal device for fine grid, change the setting of irrigation channel, laminating channel wall is adopted to install, the channel of binding face drives water hole into, the rotation of whole rotary sieve is directly driven by the rotation of motor reducer Direct driver central shaft, sewage is directly entered in screen drum by diversion trench, slag thing is trapped within rotating screen tube inner surface, screen drum constantly rotates continuous salvaging, when slag thing is brought to screen drum top, effect by gravity and wash-down water makes it drop in slag gathering hopper, achieves the object that slag thing is separated with sewage.This device structure is simple, stable and reliable operation.This device is the same with above Barrate type grilling dirt remover is all adopt net cylinder rotating filter, all has filtering accuracy high, effective feature of damming.Because dirt removal device for fine grid part screen drum is emerging in above water channel, facilitate the safety of manual cleaning and maintenance, simultaneously the half of filtration area nearly screen drum volume, solves Barrate type grilling dirt remover filtration efficiency low, the problems such as difficult clean and maintenance.But the maximum defect of this device to carry out squeezing and the conveying of filter residue, because the slag thing salvaged through screen drum falls into slag gathering hopper together with wash-down water, in slag gathering hopper, wash-down water and slag thing mix and also will carry out secondary separation.
Above-mentioned deficiency still has the place being worth improving.
Summary of the invention
The utility model, for the deficiencies in the prior art, provides a kind of structure more simple, runs more stable, cleans, safeguards more convenient safety, and integrates and retain salvaging, squeezing, conveying function, can realize the sieve dirt remover of working day and night of full automatic control.
For realizing the utility model object, provide following technical scheme: sieve dirt remover of working day and night, comprise the screen drum be positioned in water channel, central shaft and spiral conveyer, screen drum cylinder face is provided with filtering net, filtering net is Stainless Steel Cloth or porous plate, described screen drum axis and water channel plane-parallel, screen drum one side opening, opposite side is closed, it is characterized in that central shaft is made up of stationary shaft and turning axle, turning axle is arranged at screen drum inside, the center of the blind end internal surface of screen drum is fixed in one end, turning axle the other end coupling shaft bearing sleeve one end, the bearing housing the other end is connected and fixed axle one end, described stationary shaft is fixedly installed in water channel pool wall upper end, blind end outside surface center is provided with spindle nose, spindle nose is installed on the bearing support that is arranged on water channel pool wall, described spiral conveyer is fixed on stationary shaft, spiral conveyer end stretches in screen drum, spiral conveyer main shaft end arranges drive with turning axle and is connected, on described spiral conveyer, slag gathering hopper is just to below screen drum top.
As first optimal technical scheme: when spiral conveyer be tilted to down be fixed on stationary shaft time, transmission mechanism comprises the small conical gear being arranged at spiral conveyer main shaft end and the large conical gear be arranged on turning axle, large small conical gear engaged transmission.Bevel gear ∑ ≠ 90 °.
As second optimal technical scheme: when spiral conveyer be tilted to down be fixed on stationary shaft time, transmission mechanism comprises universal coupling and straight/oblique circular cylinder gear/sprocket wheel.
As the 3rd optimal technical scheme: when described spiral conveyer level is fixed on stationary shaft, transmission mechanism comprises the small Spur gear being arranged at spiral conveyer main shaft end and the large straight gear be arranged on turning axle, large small Spur gear engaged transmission.
