Abstract

The utility model relates to a toper filter, this toper filter's main part is the toper structure, and its upper end sectional area is greater than the lower extreme sectional area, this toper filter's upper and lower both ends are equipped with the water distribution plate who has the even aperture that distributes, filter material among this toper filter is the cordage, and this toper filter's upper and lower both ends are fixed in at these cordage both ends. When sewage filtered, sewage was through rope form fibre, the feasible wherein continuous gradient density filter layer of rope form fibration of toper structure. Comparing that to use granule filter material filter to hold back the volume of particulate matter in the tradition big, guaranteeing out water quality of water simultaneously, filtration efficiency is higher, and the filter material utilization ratio also improves, does not have the problem that back flush in -process filter material runs off.

Description

Conical filter

Technical field

The utility model relates to filtering technique in water treatment, provides a kind of conical filter.

Background technology

Filtration is that one forces solid, liquid two-phase mixture by porous media, and solid is retained on medium, thus realizes the method for Separation of Solid and Liquid.At present, filtering technique is a kind of method of removal impurities in water the most conventional in sewage treatment area.

Traditional filtrate comprises quartz sand, manganese sand and anthracite etc., and filter type mainly by filtrate natural packing, realizes Separation of Solid and Liquid by the space between filtrate.

Novel filtrate mainly comprises polymeric material, yarn fabric, fiber and film.Novel filter material has in filtering layer space large compared to traditional sand filtration filtrate, and filtering material resistance is little easily realizes the advantages such as in-depth filtration.

But existing most of filter exists, and particle is easily at surface sediment, and filtrate upper strata is easily blocked, middle lower floor such as can not to play a role completely at the problem.Granule filter material, in backwash process, easily runs off; Novel filter material space is large, retains that efficiency is low effectively can not ensure effluent quality.

Utility model content

The utility model object is the pluses and minuses for above-mentioned filtrate, proposes a kind of novel conical filter.

A kind of conical filter, its feature is, the main body of this conical filter is pyramidal structure, and the upper end cross sectional of this conical filter is greater than lower end cross sectional area; The two ends up and down of this conical filter are provided with the water distributing plate with the aperture that is evenly distributed; Filtrate in this conical filter is cordage, and the two ends up and down of this conical filter are fixed at these cordage two ends.

Preferably, this cordage has comparatively multiple-limb, and this branch is staggered to form filter screen.

Be improved to by traditional filter and have pyramidal structure formation, wherein filtrate uses cordage, and cordage has comparatively multiple-limb, cordage branch is staggered to form filter screen, thus reaches the object of filtration.The large lower end cross sectional area of conical filter upper end cross sectional is little, and cordage branch is more staggered closeer, and the hole of formation is more and more less.When sewage water filtration, sewage is through cordage, and pyramidal structure makes wherein cordage form continuous print Graded Density filter course, amount compared to conventional filter trapped particles thing is large, can ensure effluent quality, filter efficiency is higher, and filtrate utilization rate also improves simultaneously; During backwash, ingoing stream forms impulsive force, makes backwash more thorough, and cordage has stationarity simultaneously, can effectively avoid running off in backwash process.

Conical filter, compared with conventional filters, has following advantage: the structure of (1) conical filter makes cordage have the special construction that space is more and more less from top to bottom; (2) impurity be retained in cordage along with the carrying out of filtering gets more and more, larger can not being fully used in space, filtrate upper strata, overcomes impurity in conventional filter and assembles the phenomenon of blocking filtrate on upper strata; (3) amount compared to conventional filter trapped particles thing is large, can ensure effluent quality simultaneously; (4) filter effect and filtrate utilization rate can effectively be improved; (5), during backwash, be more easily rinsed by the particle that filtrate retains.Cordage has stationarity, can effectively avoid running off in backwash process.

Accompanying drawing explanation

Fig. 1 is the structural representation of the conical filter of the utility model one embodiment

Detailed description of the invention

Lift preferred embodiment below, and come by reference to the accompanying drawings clearlyer intactly the utility model to be described.

Fig. 1 shows a kind of conical filter, and the main body of this conical filter is pyramidal structure, and the upper end cross sectional of this conical filter is greater than lower end cross sectional area.The two ends up and down of this conical filter are provided with the water distributing plate with the aperture that is evenly distributed, and upper end open arranges water inlet water distributing plate 1, and lower ending opening arranges water outlet water distributing plate 3, and being provided with to be beneficial to of water distributing plate makes water can evenly enter filtrate district; Filtrate in this conical filter is have the cordage 2 compared with multiple-limb, and the two ends up and down of this conical filter are fixed at these cordage 2 two ends.These branches of cordage 2 are staggered to form filter screen, and the structure of conical filter makes the hole of filter screen more and more less from top to bottom.

In sewage disposal process, sewage enters filter along water inlet 4 direction, and sewage distributes and enters filtrate district by water inlet water distributing plate 1 uniformly, and filtrate district filtrate is made up of cordage 2.When sewage water filtration, sewage is through cordage 2, and pyramidal structure makes wherein cordage 2 form continuous print Graded Density filter course, and filter efficiency is higher, and filtrate utilization rate also improves.Finally, the water through filtering leaves filter along delivery port 5 direction.When filter needs backwash, flushing water oppositely enters filter from delivery port 5 direction, enters filtering area, rinses cordage 2, takes away the particle that cordage 2 retains, and finally oppositely leaves filter along water inlet 4 direction.

Claims

1. a conical filter, is characterized in that, the main body of this conical filter is pyramidal structure, and the upper end cross sectional of this conical filter is greater than lower end cross sectional area; The two ends up and down of this conical filter are provided with the water distributing plate with the aperture that is evenly distributed; Filtrate in this conical filter is cordage, and the two ends up and down of this conical filter are fixed at these cordage two ends.

2. conical filter according to claim 1, it is characterized in that, this cordage has comparatively multiple-limb, and this branch is staggered to form filter screen.
