Abstract
The utility model discloses a multi-medium filter. The multi-medium filter comprises a shell (1) and supporting legs (2), wherein a water inlet (3) is formed in the top of the shell (1) and a filtering plate (4) is arranged at the lower part of the shell (1); a filtering layer (5) is arranged on the upper side of the filtering plate (4) and the filtering layer (5) comprises an anthracite layer (6), a quartz sand layer (7) and a pebble layer (8) from top to bottom; the diameter of grains in the anthracite layer (6) and the pebble layer (8) are greater than the diameter of grains in the quartz sand layer (7); a water outlet (9) is formed in the bottom of the shell (1). According to the multi-medium filter disclosed by the utility model, the filtering layer is used for gradually removing suspended impurities according to the size of the grains so that the content of a filtered discharged-water suspension matter can be less than 5mg/L; meanwhile, the quartz sand layer is arranged by layers so that discharged water smoothly infiltrates under the effect of the gravity and pollutants in the water are gradually intercepted through quartz sand with different grain diameters. The whole equipment has the characteristics of simple structure, convenience in operation and good water quality of the discharged water, and is suitable for popularization and application.
Description
Technical field
The utility model relates to water-treatment technology field, specifically a kind of simple in structure, easy to operate, more medium filter that effluent quality is good.
Background technology
More medium filter is to utilize one or more filter mediums, under certain pressure, the higher water of turbidity is passed through certain thickness granular or non-grain material, thereby effectively remove the process that suspended impurity makes clarification of water, filtrate commonly used has quartz sand, anthracite, manganese sand etc., be mainly used in the water treatment turbidity removal, demineralized water, the prime pretreatment of pure water etc., although existing more medium filter filter course adopts plurality of filter media, due to the relation that does not fully take into account the order of filtration in sewage disposal, cause that filter effect is bad, effluent quality is poor.
Summary of the invention
The purpose of this utility model is the problem that exists for prior art, and a kind of simple in structure, easy to operate, more medium filter that effluent quality is good is provided.
The purpose of this utility model solves by the following technical programs:
A kind of more medium filter, the leg that comprises housing and support housing, the top of described housing is provided with water inlet, the bottom of housing is provided with filter plate, the upside of filter plate is provided with filter course, filter course comprises anthracite coal measure, quartz sand layer and boulder bed from top to bottom, and in anthracite coal measure and boulder bed, the particle diameter of particle is greater than the particle diameter of particle in quartz sand layer, and the bottom of housing is provided with delivery port.
Described quartz sand layer comprises upper quartz sand layer and the lower quartz sand layer on top, and in upper quartz sand layer, the particle diameter of particle is greater than the particle diameter of particle in lower quartz sand layer.
Described filter plate is provided with equally distributed drain cap.
Described filter plate adopts support member to be fixed in housing.
Described housing is provided with the visor in order to observe.
One side of described water inlet is provided with the exhaust outlet that is communicated with the housing inner chamber.
All be provided with manhole on the housing of described filter course upside and filter plate downside.
The utility model has the following advantages compared to existing technology:
When the utility model uses, former water was from top to bottom by filter course, in water, suspension was retained down by the anthracite coal measure at top due to absorption and mechanical choked flow effect; When current are middle through filtering layer, due to the sand grains in quartz sand layer arrange tightr, make in water particulate that more chance and sand grains collision are arranged, so in water, flocculation material, suspension and sand grain surface adhere to mutually, in water, impurity is trapped in quartz sand layer, thereby the water quality that obtains clarifying, the aqueous suspension that goes out after filtering can be below 5 mg/litre; Utilize simultaneously the density of different medium in filter course different, the disorder of filter material layer when having avoided in the backwash process bottom-up cleaning filtrate of current.
Water outlet after quartz sand layer layering of the present utility model is arranged to filter is oozed under under Action of Gravity Field smooth and easy, quartz sand through different-grain diameter is progressively held back water pollutant, the characteristics that Whole Equipment has is simple in structure, easy to operate, effluent quality is good, suitable promoting the use of.
Description of drawings
Accompanying drawing 1 is structural representation of the present utility model.
Wherein: 1-housing; 2-leg; 3-water inlet; 4-filter plate; 5-filter course; 6-anthracite coal measure; 7-quartz sand layer; 8-boulder bed; 9-delivery port; 10-upper quartz sand layer; 11-lower quartz sand layer; 12-drain cap; 13-support member; 14-visor; 15-exhaust outlet; 16-manhole.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is further described.
As shown in Figure 1: a kind of more medium filter; The leg 2 that comprises housing 1 and support housing 1; Be provided with water inlet 3 at the top of housing 1; One side of water inlet 3 is provided with the exhaust outlet 15 that is communicated with housing 1 inner chamber; The bottom of housing 1 is provided with adopts support member 13 to be fixed on the interior filter plate 4 of housing 1; Filter plate 4 is provided with equally distributed drain cap 12; The upside of filter plate 4 is provided with filter course 5; Filter course 5 comprises anthracite coal measure 6 from top to bottom; Quartz sand layer 7 and boulder bed 8; In anthracite coal measure 6 and boulder bed, the particle diameter of 8 particles is greater than the particle diameter of particle in quartz sand layer 7; Quartz sand layer 7 comprises upper quartz sand layer 10 and the lower quartz sand layer 11 on top; In upper quartz sand layer 10, the particle diameter of particle is greater than the particle diameter of particle in lower quartz sand layer 11; The bottom of housing 1 is provided with delivery port 9.All be provided with manhole 16 in addition on the housing 1 that is provided with on housing 1 in order to the visor 14 observed and filter course 5 upsides and filter plate 4 downsides.
When the utility model uses, by depth-type filtration, particle larger in water is removed at the top layer of filter course 5, less particle is removed than the depths filter course 5, thereby makes the standard after water quality reaches coarse filtration.Specifically former water is from top to bottom when the filter course 5, and in water, suspension is retained down by the anthracite coal measure 6 at top due to absorption and mechanical choked flow effect; When current are middle through filtering layer 5, due to the sand grains in quartz sand layer 7 arrange tightr, make in water particulate that more chance and sand grains collision are arranged, so in water, flocculation material, suspension and sand grain surface adhere to mutually, in water, impurity is trapped in quartz sand layer, thereby the water quality that obtains clarifying, the aqueous suspension that goes out after filtering can be below 5 mg/litre; Utilize simultaneously the density of filter course 5 interior different mediums different, the disorder of filter material layer 5 when having avoided in the backwash process bottom-up cleaning filtrate of current.Water outlet after quartz sand layer 7 layerings are arranged to filter is in addition oozed under under Action of Gravity Field smooth and easy, the characteristics that overall structure has is simple in structure, easy to operate, effluent quality is good, suitable promoting the use of.
Above embodiment only is explanation technological thought of the present utility model, can not limit protection domain of the present utility model with this, every technological thought according to the utility model proposes, any change of doing on the technical scheme basis is within all falling into the utility model protection domain; The technology that the utility model does not relate to all can be realized by prior art.
