Abstract

The invention relates to a multi-media filter with separation plates. The invention belongs to the field of a filtering system. A manhole, a gas discharging valve, a water outlet port, and a backwash water discharging port are provided on a filter housing. An inlet water distributor is arranged in the filter housing. In-housing separation plates are arranged in the filter housing. The in-housing separation plates equally separate the cavity space in the filter into 4 small units. Anthracite filter material layers and active carbon filter material layers are arranged in the small units. A quartz sand filtering layer is arranged below the active carbon filter material layers. An interlayer sieve plate is arranged on the bottom of the quartz sand filtering layer. Water-guiding caps are provided on the interlayer sieve plate. With the filter provided by the invention, phenomena of filter material non-uniform scouring, filter material loss, and easy backwashing layer disorder can be avoided.

Description

A kind of more medium filter with dividing plate

Technical fieldThe present invention relates to a kind of more medium filter with dividing plate, belong to the filtering system field.

Background technologySingle filter media effect is undesirable, more medium filter arises at the historic moment, wherein quartz sand, activated carbon are the filter packings of comparatively commonly using, there is defective at present in more medium filter, as: when bad or water flow is excessive when the water distribution effect, cause filter material surface to wash away inequality, filtrate easily runs off, the easy disorderly layer of backwash.

Summary of the inventionIn view of the defective of prior art existence, the purpose of this invention is to provide a kind of filtrate of can avoiding and wash away the easily more medium filter with dividing plate of random layer phenomenon generation of inequality, filtrate loss, backwash.

For achieving the above object, the technology used in the present invention solution is: a kind of more medium filter with dividing plate, manhole, vent valve, water outlet, backwash water port are installed on the filter body, be provided with water inlet distributor in the filter body, in filter body, be provided with the housing internal partition, the housing internal partition is divided into 4 junior units with strainer inner chamber body space, be provided with ANTHRACITE FILTER MEDIA layer and the activated-carbon filter bed of material in the junior unit, have the quartz sand filtration layer at the activated-carbon filter bed of material, quartz sand filtration layer bottom is the interlayer sieve plate, and the water guide cap is arranged on the interlayer sieve plate.

A kind of more medium filter with dividing plate, its beneficial effect is: the filtering layer of described more medium filter adopts the laying form of different grain size filtrate, lower floor is secondary quartz sand, large particle diameter quartz sand can play good supporting role, small particle size quartz sand also plays a protective role except supporting role, prevents that strainer from running material; The little activated carbon granule of particle diameter is adopted in the middle level, and filtration, advantages of good adsorption effect play smart filter effect; The upper strata is the ANTHRACITE FILTER MEDIA layer, is characterized in that particle diameter is large, lightweight, density be little, and porosity can play macrofiltration greater than 50%, is not easy to stop up, and plays simultaneously the effect of prolection carbon-coating; Dividing plate at the middle and upper levels is 4 junior units with filter chamber body space isodisperse, plays the less light filter material of fixedly filtrate, particularly density, effectively prevents easily the mutually phenomenon of random layer.

Description of drawings

Fig. 1 is a kind of structure diagram of the more medium filter with dividing plate.

Fig. 1 Reference numeral is as follows: 1, filter body, 2, water inlet distributor, 3, vent valve, 4, the housing internal partition, 5, water guide cap, 6, the interlayer sieve plate, 7, water outlet, 8, the backwash water port, 9, manhole, 10, the quartz sand filtration layer, 11, the activated-carbon filter bed of material, 12, the ANTHRACITE FILTER MEDIA layer.

Embodiment

In the structure diagram of Fig. 1 shows a kind of more medium filter with dividing plate, its primary structure is: manhole 9 is installed on the filter body 1, vent valve 3, water outlet 7, backwash water port 8, be provided with water inlet distributor 2 in the filter body, in filter body, be provided with housing internal partition 7, housing internal partition 7 is divided into 4 junior units with strainer inner chamber body space, be provided with ANTHRACITE FILTER MEDIA layer 12 and the activated-carbon filter bed of material 11 in the junior unit, have quartz sand filtration layer 10 at the activated-carbon filter bed of material 11, quartz sand filtration layer 10 bottom are interlayer sieve plate 6, and water guide cap 5 is arranged on the interlayer sieve plate.

Quartz sand can play good supporting role and provide protection, prevents that strainer from running material; The little activated carbon granule of particle diameter is adopted in the middle level, and filtration, advantages of good adsorption effect play smart filter effect; The upper strata is ANTHRACITE FILTER MEDIA layer 12, is characterized in that particle diameter is large, lightweight, density be little, and porosity can play macrofiltration greater than 50%, is not easy to stop up, and plays simultaneously the effect of prolection carbon-coating; Dividing plate at the middle and upper levels is 4 junior units with filter chamber body space isodisperse, plays the less light filter material of fixedly filtrate, particularly density, effectively prevents easily the mutually phenomenon of random layer.
