Abstract
The utility model provides an anti-clogging filter head, which is characterized by mainly comprising a filter cap, a filter element and a rod, wherein the upper end of the filter cap is provided with a vertical guide plate, a transversal guide plate and a top; the filter element is an X-shaped filter element mainly comprising vertical grating plates and a transversal intercepter plate; the X-shaped filter element is formed by the parallel grating plates which are upwards obliquely arranged towards the inner side; the filter element is arranged in the upper cavity of the rod; and the rod is connected with the filter cap. The filter head has the advantages that sewage faces the upper inclined direction to enter the filter element, and suspended solid particles, fibers, fragments and the like hardly enter an overflow slot due to the inertia effect but are isolated on the cone top of the X-shaped filter element and are easier to flush out when in back flushing; the width of a charging strip pore of the filter cap is less than the minimum particle size of a ceramsite filter material, and therefore, the ceramsite filter material can not pass through the strip pore to be transferred into a water distribution chamber to run off; the filter head is upwards connected and assembled on the water distribution chamber below a filter plate; the X-shaped filter element can be randomly replaced from the water distribution chamber without turning over a filter tank to clear the ceramsite filter material and supporting cobbles in the tank.
Description
Technical field
The utility model relates to the anti-clogging plug filter, is applicable to the special-purpose anti-clogging plug filter of BAF.
Background technology
In sewage disposal technology, BAF is a kind of sewage treatment process of new bio embrane method.This technology has the effect of removing SS, COD, BOD, nitrated, denitrogenation, dephosphorization, removal AOX (harmful substance), be characterized in integrating bio-oxidation and collect and stay suspended solids, saved post precipitation pond (second pond), its volumetric loading, hydraulic load are big, hydraulic detention time is short, and required initial cost is few, and effluent quality is good, operation energy consumption is low, and working cost is low.
BAF contains more suspended substance (particularly plastics film, floss, fragment) from filter plate water inlet down in the water, the BAF long-time running, and filter stops up and is difficult to avoid, in case occur being difficult to clean.Therefore the Sewage Plant of some this technology is in operation, and once causes filter plate such serious consequence of throwing.On distributing water room's pool wall under filter plate, establish the access opening in the design, also utilize the rapid precipitation of filter tank water level, back flush filter from top to down, the corresponding measure that tamper is drained.But existing filter often has following problem to occur in the practical engineering application of BAF:
1, the filter situation that adds at filtrate, can fracture occur, stop up in the use causes the forfeiture of filter proper function, changes filter if desired, a large amount of ceramic grain filters and supporting layer cobble in the filter tank of need moving, and workload is huge;
2, the BAF filter is because in sewage treatment process, sewage generally contains a large amount of suspended solids and fiber, fragment etc., after operation for some time, existing ubiquity filter seriously stops up the problem that sewage treatment capacity declines to a great extent in BAF.
Though some BAF engineering has been carried out such or such transformation to filter, increased filter cap under the grating, this kind filter cap down also is easier to by obstructions such as fiber, fragments.For this reason, often the filter in the filter tank to be changed.
Summary of the invention
The purpose of this utility model is to provide the filter of a kind of difficult obstruction, easy to clean.
The utility model provides a kind of anti-clogging plug filter, it is characterized in that: mainly comprise filter cap, filter core and bar portion, there are vertical flow deflector, horizontal flow deflector and top in filter cap upper end, filter core is the X-shaped filter core of mainly being made up of vertical flase floor and horizontal intercepter plate, the X-shaped filter core is to be made of parallel and the flase floor of arranging that tilts to the inside, filter core is contained in the upper chambers of bar portion, and bar portion is connected with the filter cap; The work of X-shaped filter core the time make sewage obliquely direction enter filter core, changed water (flow) direction, suspended solids and fiber, fragment etc. are because inertia effect, the less tank that entered, and be isolated in the cone top part of X type filter core, when the precipitation of operation back flushing filter tank, the dirt of the cone top part of X type filter core is rinsed out, prevents the obstruction of dirt to filter effectively.
The anti-clogging plug filter that the utility model provides, the horizontal intercepter plate of its filter core can have centre hole, makes that the dirt of cone top part of X type filter core is easier to be rinsed out, strengthens the back flushing effect.
The anti-clogging plug filter that the utility model provides, can there be air inlet port and/or air inlet seam in its bar subordinate portion, helps the discharge of gas in the sewage.
The anti-clogging plug filter that the utility model provides, its bar portion can be threaded with the filter cap, and bar portion or filter cap have flat horizontal surface (comprising six sides, four directions etc.), so that safeguard filter core.
The anti-clogging plug filter that the utility model provides, its filter cap can be threaded with filter plate, and the filter cap has flat horizontal surface (comprising six sides, four directions etc.), so that the loading and unloading of filter cap.
The anti-clogging plug filter that the utility model provides, the width of the cylindrical void that the vertical flow deflector of its filter cap and horizontal flow deflector form is preferably 2.5～5mm, has both guaranteed that cylindrical void can be not blocked, guarantees that again ceramic grain filter can not run off.
The anti-clogging plug filter that the utility model provides, its advantage is: the work of X-shaped filter core the time make sewage obliquely direction enter filter core, changed water (flow) direction, suspended solids and fiber, fragment etc. are because inertia effect, the less tank that entered, and be isolated in the cone top part of X type filter core, when the precipitation of operation back flushing filter tank, the dirt of the cone top part of X type filter core is easier to be rinsed out, prevents the obstruction of dirt to filter effectively.Filter cap material loading cylindrical void width is less than the minimum grain size of ceramic grain filter, so ceramic grain filter can not pass cylindrical void and call in the distributing water room and run off, filter is that the distributing water room below filter plate upwards is linked and packed, can arbitrarily change the X-shaped filter core and do not need to turn over the filter tank and draw ceramic grain filter and support cobble the pond clearly from distributing water room, the maintenance and the maintenance that make it BAF be greatly convenient.
