Abstract
A filter chamber with variable pores comprises a filter chamber body, and is characterized in that an air inlet device and a water collecting device are successively arranged in the filter chamber body from top to bottom. The filter chamber with variable pores mainly adopts rough filtering materials, and realizes filtering by the aid of a total filter layer, so that surface filter of a filter layer formed in a common filter chamber is avoided, resistance of the filter layer is reduced, untimely penetration of suspended matter particles is also avoided, and filter speed further can be increased. Fine filtering materials are added into the filter layer and uniformly mixed, so that local pore rate of the rough filtering materials is greatly reduced, flocculation of fine particles in sewage is improved, the filter chamber is more favorable for removing the fine particles, and sewage interception ability of the filter chamber is greatly increased. The filter chamber reduces total equipment investment and cost, is small in occupied space and better in filtering effect, shortens filtering time, reduces operation procedures, and can realize full automatic control by the aid of a pneumatic valve and a PLC (programmable logic controller).
Description
Technical field
The utility model relates to the filter tank device, especially a kind of change hole filter tank.
Background technology
At present, the usefulness that the filter tank has removes the suspension in the water, to obtain the lower water of turbidity; Has plenty of the water that is used for removing in the mud, to obtain the lower mud of water content.
Existing filter tank only forms the surface filtration of filtering layer, and the filtering layer resistance is bigger, causes penetrating too early of suspended particle, and filtering velocity is slower; The local porosity of filtrate is bigger, and the flocculation of fine particle is not obvious in the sewage.
Summary of the invention
The purpose of this utility model is to provide a kind of change hole filter tank, and this change hole filter tank has overcome above-mentioned drawback.
The technical solution of the utility model is:
A kind of change hole filter tank comprises the filter tank body, is provided with inlet duct and captation in the body of described filter tank from top to bottom successively.
The many air intake branches that described inlet duct comprises the inlet manifold and is communicated with the inlet manifold, the inlet manifold is positioned at the air intake branch top, and the air intake branch below is provided with air intake branch channel-section steel support.
Described air intake branch is provided with a plurality of drain caps.
Described captation comprises water header and the many arms that catchment that are communicated with water header, and the arm below of catchmenting is provided with the arm channel-section steel support that catchments.
Described water header is positioned at the groove of bottom, filter tank.
The beneficial effects of the utility model are:
What mainly used in change hole of the present utility model filter tank is coarse media, it relies on whole filtering layer to filter, and has avoided general filter chamber to form the surface filtration of filtering layer like this, has reduced the filtering layer resistance, also avoid penetrating too early of suspended particle, can also improve filtering velocity; The adding of fine filtering material and in filtering layer mixing greatly reduced the local porosity of coarse media, improved the flocculation of fine particle in the sewage, more help removal to fine particle, also greatly improved the retaining power in filter tank.The better effects if that total equipment investment expense reduces, takes up an area of is little, filter, shortened filtration time, reduced operational sequence.Mix pneumatic operated valve and PLC and can carry out Automatic Control.
Description of drawings
Fig. 1 is collector pipe, the air inlet pipe elevation in change hole of the present utility model filter tank.
Fig. 2 is the inlet duct plane in change hole of the present utility model filter tank.
Fig. 3 is the captation plane in change hole of the present utility model filter tank.
Among the figure: 1 is the arm channel-section steel support that catchments for water header, 6 for air intake branch channel-section steel support, 7 for the arm that catchments, 5 for air intake branch, 4 for drain cap, 3 for inlet manifold, 2.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described:
As Fig. 1, a kind of change hole filter tank comprises the filter tank body, is provided with inlet duct and captation in the body of described filter tank from top to bottom successively.
As Fig. 2, described inlet duct comprises inlet manifold 1 and the many air intake branches 3 that are communicated with inlet manifold 1, and inlet manifold 1 is positioned at air intake branch 3 tops, and air intake branch 3 belows are provided with air intake branch channel-section steel support 6.Described air intake branch 3 is provided with a plurality of drain caps 2.
As Fig. 3, described captation comprises water header 5 and the many arms 4 that catchment that are communicated with water header 5, and arm 4 belows of catchmenting are provided with the arm channel-section steel support 7 that catchments.Described water header 5 is positioned at the groove of bottom, filter tank.
The operation principle in change hole of the present utility model filter tank:
Becoming the hole filter tank is a kind of drag flow deep-bed filter with " orthokinetic coagulation " theoretical design, adopts gravity filtration, and the water inlet direction is to go out under enterprising.Its adopts a kind of filter bed that mixes by a certain percentage than the bigger filtrate of normally used particle diameter of filter medium and another kind of particulate filtrate, become the particle diameter of filter medium and the shared ratio that adopt in hole deep layer filter tank and differ bigger, be equivalent to multilayer filtrate mutual superposition and arrange, its upper and lower water inlet, middle water outlet, holding filth capacity be big, it is big to exert oneself.
Filter tank of the present utility model mainly is made up of filtrate and supporting layer, inlet duct, water dispensing apparatus, turnover mill weir chamber and valve etc., filter tank design even water distribution (guaranteeing has the certain liquid level height above the filtrate), good backwash effect is arranged, and the backwash water consumption is low, operates steadily.
Embodiment recited above is described preferred implementation of the present utility model; be not that design of the present utility model and scope are limited; do not breaking away under the utility model design concept prerequisite; common engineers and technicians make the technical solution of the utility model in this area various modification and improvement; all should fall into protection domain of the present utility model, the technology contents that the utility model is asked for protection all is documented in claims.
