Description

The continuous automatic filter of the active sand of air supporting flushing type
Technical field
Utility model is about being filtrate to water treatment (particularly oily waste water treatment) with quartz sand, be improving equipment to the sand filtering device of continuous wash filtrate, relate in particular to the structure of the cleaning method and the washer of filter leaching material, it not only can filter suspension but also can leach oil and colloid.
Background technology
At present, the continuous wash sand filtering device can only be filtered suspension, because the oil and the viscosity of colloid can't clean up greatly, filtrate can't be regenerated, so oil strain and colloid are undesirable.Chinese patent 01250908.6 washed-out sand mode is that sand extraction tube is directly sent into the washed-out sand groove to the sand that pollutes, and by sand-washing device, enters clean water area.Because backwash water is pressed with limit, will inevitably into dirts such as an a spot of suspension, colloid will be brought, just more can't the cleaning of oils.The industrial wastewater particularly waste water of petroleum chemical industry exists big gauging and polymer, needs novel technical method to solve.
Summary of the invention
In order to overcome the shortcoming of common continuous sand filter, provide the equipment of a kind of energy filtering oil, suspension and colloid.The purpose of this utility model is to realize like this, by sand filter lower taper tank body, interior dress filtrate, the bottom is provided with the current stabilization water-locator and is connected with water inlet pipe, be provided with sand extraction tube was connected with a jar end in the outside of tank body, air pump is connected with the sand-suction nozzle of sand extraction tube, the upper end of sand extraction tube is over against the taper sand trap of sand-washing device, sand separator directly is connected with the first washed-out sand chamber of sand-washing device, and the middle part of the first washed-out sand chamber is provided with annular sand developing tube, is furnished with the outside current perforation of certain angle on the sand developing tube, the first washed-out sand chamber connects the second washed-out sand chamber, indoorly also be furnished with annular sand developing tube, the bottom of chamber is provided with the air supporting head, and adjustable flushing mill weir is communicated with the sub-sand chamber, the backwash mill weir connects the backwash effluent trough, be furnished with air bag in jar and divide filter sand and regulate water distribution, water leg is arranged at jar top, and water leg is connected with outlet pipe.
The course of work of the present utility model, the sewage that enters tank body is evenly distributed on sewage on the filter bed by water-locator, entering feeder by depth filtration, deep bed filtration generation clear water is discharged by delivery port, suspension, the wet goods dirt is stopped by filter sand, carry sand and use sand-suction nozzle, the filter sand of oil-containing and impurity is evenly sent into, spray into sand separator by the sand extraction tube forward, the taper sand separator of particular design makes sand be split into very thin sand film, this sand film as thin as a wafer by the flushing of air supporting and eddy current type current and centrifugal action down the filter sand of weight to be in edge descending, lighter dirt is upwards discharged in the centre, air supporting is that the bottom from sand-washing device begins to arrive the water surface, some light dirts that make filter sand not clean adhesion rise to the water surface again, and the dirt after the flushing flows to sewage draining exit, has improved regeneration and filter effect so greatly.Filter sand is filtered and carries out at the same time by constantly backwash, has improved operating efficiency.Advantage of the present utility model is to have used gravity and collects filtrate and distribute filtrate, the utilization air force is carried sand, the vibration of utilization air separates sand and dirt, in sand-washing device, utilize jet generation eddy current and cooperate air supporting to clean filtrate, realize fine purifiation, dirt utilizes current to discharge, and filtrate utilizes gravity to distribute downwards, and filter bed makes to keep clean eventually and filters efficiently.Be not less than 85% by advance copy utility model suspended substance removal rate, oil removal rate is not less than 93%.Therefore, we can say the utility model high efficiency, save the area, operating cost is low and the oil removing ability is strong filter method.

Specific embodiments
For a more detailed description to the utility model for example below in conjunction with accompanying drawing:
Fig. 1 is a structural representation of the present utility model.
As shown in Figure 1.The continuous automatic filter of the active sand of air supporting flushing type comprises filtering tank, the certain thickness filter sand of crossing in jar, water inlet pipe and outlet pipe, its characteristics comprise tank body 3, the bottom of tank body is provided with water-locator 5, the top of water-locator 5 is provided with air bag 4, can help water distribution, also distribute simultaneously filter sand, be provided with filter sand suction nozzle 7 at the bottom of the vertebra of jar, the external margin of tank body is provided with sand extraction tube 6, the sand-washing device 17 that faces toward suitable for reading of sand extraction tube, be provided with the annular sand developing tube 15 of washed-out sand one Room in the sand-washing device 17, washed-out sand two Room also are provided with annular sand developing tube 16, and the upper end of sand-washing device 17 is connected with sewage discharge mill weir and leads to sewage draining exit 1, and water leg 8 is arranged at jar top, water slug pump 9 is for providing the high-pressure water sand-washing device, and air pump 10 provides source of the gas for carrying sand.Specific embodiments, sewage enters in the tank body, being provided with water-locator 5 by the bottom of tank body is distributed in sewage on the casting bed of filtration, edge along air bag enters water leg 8 by filter bed, efflux by delivery port, the filter sand that pollutes by the awl of jar at the bottom of filter sand suction nozzle 7 suck, deliver to tank deck by sand extraction tube 6, by top blast tube 11 filter sand is sprayed to sand separator 14, make the filter sand of oil-containing and impurity evenly send into sand-washing device 17, spray into sand separator 14 by sand extraction tube 6 forwards, the taper sand separator 14 of particular design makes sand be split into very thin sand film, this sand film is as thin as a wafer produced centrifugal action by the eddy current type current flushing that annular sand developing tube 15 produces, and the heaviest under the action of the centrifugal filter sand is in the edge to descending, the lighter dirt emersion that makes progress in the centre, air supporting simultaneously 18 is that the bottom from sand-washing device 17 begins air supporting to the water surface, make filter sand with ing some light dirts of clean adhesion rise to the water surface again, the dirt after the flushing flows to sewage draining exit 1.The filter sand of wash clean, distributes at the bottom of jar by air bag 4 under the gravity effect along the edge of sand-washing device 17.
