Abstract
The utility model discloses a filtering head, in particular to a upwards installed anti-blockage filtering head for a biological aerated filtering tank, which comprises an upper filtering cap (1), a fixed component (5) connected with a filtering plate, a filtering bar (2) and a lower filtering cap (3); the upper filtering cap (1)is connected with the lower filtering cap (3) sequentially through the fixed component (5) and the filtering bar (2); the lower filtering cap presents the inverted conical shape; and an water inlet of the lower filtering cap has an inclined downwards structure. The filtering head has the advantages of not being blocked easily, being washed easily, and being changed simply.
Description
Technical field
The utility model relates to a kind of filter, and what relate in particular to a kind of BAF upwards assembles the anti-clogging plug filter.
Background technology
In the BAF sewage disposal technology, for guarantee that the filter tank normally intakes, the homogeneity of back flushing water inlet, air inlet, prior art mostly adopts filter to reach this purpose.
Existing filter often has following problem to occur in practical engineering application: the situation that (1) filter adds at filtrate, can fracture occur, stop up in the use, cause the forfeiture of filter proper function, change filter if desired, a large amount of filtrates and supporting layer cobble in the filter tank of need moving, workload is big; (2) BAF now generally is used for sewage treatment project, and owing to generally containing suspended solid and fiber, fragment etc. in the sewage, filter operation for some time stops up easily.
Though some engineering is transformed filter, increased filter cap under the grating, this kind filter cap down also is easier to be blocked by fiber, fragment etc., must change filter.
The utility model content
At the shortcoming of prior art, the purpose of this utility model provides a kind of difficult obstruction, going up to assembling anti-clogging plug filter of should clearing up.
For achieving the above object, the technical solution of the utility model is: a kind of anti-clogging plug filter that upwards assembles, comprise upward filtration cap, the mounting block that is connected with filter plate, filter bar and filter cap down, the upward filtration cap is connected by mounting block, filter bar and following filter cap successively, this time filter cap is back taper, and the water-in of filter cap is provided with tiltedly down to water inlet structure down.
Tiltedly down parallel and grid that tilt obliquely laterally constitutes by plurality of rows to structure.
Under filter cap by connecting down the filter cap thread and filtering bar and be connected, mounting block is connected with filter plate by thread fiting mode.
This upward filtration cap comprises crossing the pool, being located at crossing tank and being located at the self tapping awl syndeton of upper end, pool in the pool of being connected with mounting block.
Cross the pool and be stage body shape structure, the wide of tank is 1.5～3.5mm excessively, and tank is processed into different groove widths and groove number according to filtrate kind difference excessively.
Upward filtration cap, mounting block and the moulding of filter bar integral molded plastic.
Compared with prior art, of the present utility model going up when the work of assembling anti-clogging plug filter, because the filter cap is back taper down, the water-in of filtering cap down is tiltedly down to structure, so water inlet is tiltedly down to water inlet, sewage is because back taper is changed the direction of a stream of water at the formed obtuse angle of filter cap down, and suspended solids and fiber, fragment etc. are owing to inertia effect, and less entering down with current filtered cap; In backwash process, backwash water, backwash gas in the water inlet intake process to filter down cap to wash away direction opposite with the water inlet direction, be blocked in down that the dirt of filtering in the cap slit is easier to be rinsed out, can prevent the obstruction of dirt effectively to filter.
In addition, in the utility model, the top of upward filtration cap is provided with self tapping awl syndeton, make that the upward filtration cap is easy to jacking filtrate supporting layer when changing filter, and when taking off filter, supporting layer support filtrate is owing to bridging action, and filtrate can not fall to running off from the filter open holes.And following filter cap is connected with the filter bar by filter cap thread under connecting, and makes and filters cap disassembly, cleaning fast down.
Description of drawings
Fig. 1 is to the structural representation that assembles the anti-clogging plug filter on the utility model;
Fig. 2 is to the cross-sectional view of assembling the anti-clogging plug filter on the utility model.
Among the figure: 1, upward filtration cap 2, filter bar 3, down filter cap 4, self tapping awl syndeton 5, mounting block 6, connect down filter cap thread 7, cross pool 8, cross tank
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figures 1 and 2, a kind of going up to assembling anti-clogging plug filter, the mounting block 5 that comprise upward filtration cap 1, is connected with filter plate, filter bar 2 reach filter cap 3 down, upward filtration cap 1 is connected by mounting block 5, filter bar 2 and following filter cap 3 successively, this time filter cap 3 is back taper, and the water-in of filter cap 3 is provided with tiltedly down to water inlet structure down.This filter can be to assembling from the distributing water room, and repair and replacement are convenient; Back taper is tiltedly filtered cap down to inlet type down makes suspended substance be difficult for entering the filter cap, and cleans easily.Wherein, tiltedly down parallel and grid that be located at water-in constitutes by plurality of rows to structure, and grid tilts laterally obliquely, so that current can be along grid tiltedly down to flowing to water-in.In addition, upward filtration cap 1, mounting block 5 and the 2 integral molded plastic moulding of filter bar.
In the present embodiment, filter cap thread 6 is connected with following filter cap 3 by connecting down to filter bar 2.Certainly, following filter cap 3 also can be connected by the dop draw-in groove with filter bar 2, but compared with being threaded, the connection that can effectively avoid plastics fatigue to cause of being threaded is loosening, and filters cap 3 down and can repeatedly dismantle and the situation of becoming flexible can not occur.Mounting block 5 adopts thread fiting mode to be connected with filter plate, is used for filter is fixed on the filter plate built-in fitting of BAF.
This upward filtration cap 1 comprises crossing pool 7, being located at crossing tank 8 and being located at the self tapping awl syndeton 4 of 7 upper ends, pool in the pool 7 of being connected with mounting block 5, wherein, self tapping awl syndeton 4 is connected with the filtrate supporting layer, can improve the accessibility of installation and removal effectively.Cross pool 7 and be stage body shape structure, be located at the tank 8 wide 1.5～3.5mm of being excessively in pool 7, mistake pool 7 was passed through tank 8 and was realized water function, and tank 8 can be processed into different groove widths and groove number according to filtrate kind difference excessively.
Filter of the present utility model can arbitrarily be changed filter and need not carry filtrate from the upwards assembling of distributing water room of filter plate below from distributing water room, and filter is fixed on the filter plate, sewage successively through filter cap 3 down, filter bar 2, upward filtration cap 1 from distributing water room to filter material layer.
