Abstract
The utility model discloses a sewage filter, and relates to a sewage treatment device. Water distribution devices are fixed at the upper part and at the lower part in a filter casing, a pore plate is fixed in the middle, a washing water inlet, a water producing port and a discharge outlet are formed in the bottom of the filter casing, and a cobblestone layer is arranged at the lower part in the filter casing; a zeolite layer is arranged above the cobblestone layer; and an upper air inlet, an upper steam inlet and a dosing inlet are formed in the upper part of the side wall of the filter casing, and a lower air inlet and a lower steam inlet are formed in the lower part. The sewage filter is reasonable in structure design; filter nets are added on the water distribution devices and effectively prevent contact of zeolite and the water distribution devices in the washing process, as well as flowing out of zeolite, meanwhile, the hardening quantity of the filter nets is reduced, and the filter nets are convenient to clean; and hanging of solid particles on the filter nets is avoided, problems that tensile force is larger than that of a cylinder, a pull rod is broken and the like are not easily caused, and the service life of the filter is prolonged.
Description
Technical field
the utility model relates to sewage-treatment plant, relates in particular to a kind of effluent filter.
Background technology
Steam to filter heating three hours after, a small amount of oil and a large amount of tiny solid particle, giving under the state of wind and can separating from the filter wire on filter top and in the zeolite of filter bottom, are suspended in the water at middle part in filter.Backwash water after existing Steam Heating enters from bottom and rises, discharge on top from filter after filter wire, just there is damming in a large number to solid particle in the process through filter wire, water can hang over solid particle in filter wire in the past again, along with time integral filter wire is thoroughly cleaned not out after hardening; When the solid particle weight hanging in filter wire is greater than after the pulling force of cylinder, just there will be pull bar breakage problem; Filter wire after hardening has caused very large pressure to lower hole supporting plate in the time of the intake pressure bump of the highest 4 kilograms, after long-term operation by orifice plate crimp, until depart from and fall into tank bottom by steam pipe line, wind line, the distortion of alkali line pressure with tank body, filter interior equipment is caused to serious destruction.
Utility model content
The utility model is intended to for the problem existing in background technology, and a kind of effluent filter proposing.
Effluent filter of the present utility model, on filter housings, to be provided with water inlet, producing the mouth of a river and floss hole forms, top in filter housings is radially fixed with water-distributing device I, middle part is radially fixed wtih orifice plate, bottom is radially fixed with water-distributing device II, filter housings bottom is provided with flushing water inlet, produce the mouth of a river and floss hole, described water-distributing device I is with water inlet on filter head housings body sidewall and flush out the mouth of a river and be communicated with respectively, in described water-distributing device I and water-distributing device II, be all coated filter screen I, on orifice plate, cover the filter screen II being fixed wtih more than one deck, in filter housings, the below of water-distributing device II is provided with cobblestone layer, it on cobblestone layer, is zeolite layer, filter head housings body sidewall between water-distributing device I and orifice plate is provided with upper air inlet, upper enter steam port and dosing import, between orifice plate and water-distributing device II filter head housings body sidewall be provided with the next air inlet and the next enter steam port.
As further improvement of the utility model, described upper air inlet and upper enter steam port be all communicated with the distribution device I of filter housings inside, the next air inlet and the next enter steam port be communicated with the distribution device II of filter housings inside, dosing import is communicated with the cloth medicine device of filter housings inside.
As further improvement of the utility model, described water-distributing device II and distribution device II are all positioned at zeolite layer.
As further improvement of the utility model, described filter housings top is provided with cylinder valve and exhaust outlet.
As further improvement of the utility model, between the upper surface of described zeolite layer and orifice plate, distance is 0.8 meter to 1.5 meters.
Effluent filter of the present utility model, reasonable in design has increased the outflow loss that filter screen effectively stops contacting of zeolite and water-distributing device and zeolite in flushing process on water-distributing device, reduces the filter screen amount of hardening simultaneously and conveniently cleans; Avoid the solid particle prolong knot amount on filter screen, be not prone to the pulling force that is greater than cylinder, the problems such as pull bar fracture, after simultaneously also avoiding hardening in the time of high intake pressure bump the pressure to lower hole supporting plate, overcome long-term operation to orifice plate crimp until with tank body depart from fall into tank bottom by steam pipe line, wind line, the distortion of alkali line pressure, filter interior equipment is caused to the problem of serious destruction, postponed the service life of filter.
Brief description of the drawings
Fig. 1 is that axis of no-feathering of the present utility model is to cutaway view.
Detailed description of the invention
, be described further effluent filter of the present utility model below in conjunction with accompanying drawing 1.
