Abstract
The utility model relates to a sleeve filter. A plurality of filter columns are arranged between an upper filter column fixing plate and a lower filter column fixing plate and respectively comprise an inner porous support pipe and an outer porous support pipe; each inner porous support pipe is provided with an inner filter screen; an inner support grid is arranged between the inner filter screen and the corresponding inner porous support pipe; each outer porous support pipe is provided with an outer filter screen; and an outer support grid is arranged between the outer filter screen and the corresponding outer porous support pipe. The sleeve filter disclosed by the utility model has the advantages that particles with different diameters can be retained as the aperture of each outer filter screen is larger than that of each inner filter screen; for the filters with the same filtering areas, as a filter cake on each outer filter screen is loose, the water flow resistance is relatively small, and relatively thick and loose filter cake layers are formed; and the filter cake layer on the inner filter screen is relatively thin and the water resistance is relatively small, and therefore, more water flow can be treated, the required backwashing time is prolonged, and the processing efficiency is improved.
Description
Technical field
The utility model relates to a kind of sleeve filter.
Background technology
Existing filter is mainly by filter upper and lower covers, Filter column with fixedly Filter column parts, intake-outlet etc. form.Between Filter column and filter upper and lower covers, be hydrospace, the filter cover sidewall has water inlet, and delivery port is at lower cover.Filter column commonly used mostly is in the porous tubular support outside and wraps up in one deck single aperture filter screen or filter cloth at present, during filtration, under pressure-driven, current flow to filter medium with particle, particle is trapped within on filter screen or filter cloth and is removed, and the water seen through is clarified.
Individual layer commonly used single aperture filter screen or filter cloth filter post, when filtering, can be trapped in filter screen or filter cloth surface to all particles that vary in size, the particle of different-grain diameter size is trapped while piling up simultaneously, because small-particle can be filled the space that macroparticle forms, thereby can form comparatively closely knit cake layer, current are had to larger resistance, need to frequently recoil; And there is no the macropore protection support lattice between fie screen or filter cloth and porous tubular support, fie screen or filter cloth can occur directly to be sticked stay pipe and affect filter efficiency.
The utility model content
The purpose of this utility model is to provide a kind of sleeve filter, overcomes in existing product filter screen single, and long-time the use causes the not good deficiency of filter effect.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of sleeve filter, comprise sleeve upper cover and sleeve lower cover, described sleeve upper cover top is provided with the backwash delivery port, the sidewall of sleeve upper cover bottom is provided with water inlet, sleeve lower cover bottom is provided with produces the mouth of a river, be provided with the fixedly fixing lower plate of upper plate and Filter column of Filter column in the sleeve upper cover, Filter column fixedly upper plate and Filter column fixedly is provided with some Filter columns between lower plate, described Filter column comprises interior porous tubular support and outer porous tubular support, interior porous tubular support is provided with filtering net, be provided with the inner support graticule mesh between filtering net and interior porous tubular support, outer porous tubular support is provided with outer screen pack, be provided with the outer support graticule mesh between outer screen pack and outer porous tubular support.
Further, the lower end of described sleeve upper cover and Filter column fixedly lower plate with the upper end of sleeve lower cover, by clamping screw one, with clamp nut one, be connected; Sleeve upper cover and Filter column are fixedly between lower plate, Filter column fixedly is equipped with O-ring seal between lower plate and sleeve lower cover.
Further, described Filter column fixedly fixedly is connected with clamp nut two by clamping screw two at the middle part of lower plate with Filter column at the middle part of upper plate.
Further, the quantity of described clamping screw two is the 1-6 root.
The beneficial effects of the utility model are: a kind of sleeve filter that the utility model provides, the aperture of outer screen pack is greater than the aperture of filtering net, can hold back the particle of different-diameter.Filter for same filter area, because the filter cake on outer screen pack is more loose, to the resistance to water-flow less, therefore can form thicker Yu more loose cake layer, cake layer on filtering net is thinner, also less to the resistance of water, thereby can process more discharge, need the time lengthening of backwash, so improved treatment effeciency.
