Abstract
The present invention discloses a barrel type filter core with circular ring-shaped triangular net threads whose tips point outwards. The barrel type filter core is composed of a barrel type filter core (column) 1, a retainer ring 2, a slit 6, triangular net threads 7, an outer vertical rib 10 and a sewage discharge opening 9, wherein the triangular net threads 7 of the filter core are melted and connected with the outer vertical rib 10, and simultaneously are matched and welded with the retainer ring 2 to form the integral barrel type filter core. The present invention has the advantages of good automatic cleaning effect and convenient manual cleaning.
Description
The present invention relates in the water treatment system of a kind of environmental protection field, especially for the most advanced and sophisticated outside triangular net-wire cylindrical filter cartridge of annular of water treatment oil filtration.
At present, the made cylindrical filter cartridge (promptly filtering post or filter cylinder) of used triangular net-wire is inwardly most advanced and sophisticated in many or the automatic cleaning and filtering of monotubular formula.The major defect of this technology is: 1. be filtered sewage and always outwards filter by cylindrical filter cartridge is inner usually, impurity is intercepted in the wedge-shaped crevice of two triangular net-wires formation in the sewage, and be easy to by wedging, and the backwash current are ecto-entads when backwash, current by when falling the tapered region because water flow section reduces flow velocity enlarging gradually, so the backwash current weaken, influence the backwash effect, after this situation continues for some time, dirt impurity will be hardened " wedge is dead " in the tapered region, causes filtering failure.The artificial difficulty of cleaning because of the tip inwardly forms many grooves and muscle, has influenced the dirt cleaning greatly when 2. shutting down.
The objective of the invention is and to make the interior impurity of screen pack attached to there not being any wedging phenomenon around the slit between two triangle baseplanes on the one hand by the most advanced and sophisticated outside triangular net-wire cylindrical filter cartridge of a kind of annular of design; The flow through water flow section of wedge-shaped slot of backwash water ecto-entad reduces and increases flow rate of water flow gradually on the other hand, forms the nozzle act of ecto-entad, and strong rinsing out attached to the impurity around the slit and from the bottom discharged.The artificial cleaning is very easy to when shutting down in addition, because the filter core inwall is the plane.
The object of the present invention is achieved like this: design a kind of by triangular net-wire, external vertical rib, the two constitutes the annular triangular net-wire tip cylindrical filter cartridge outwardly that filter core main body, slit, snap ring, sewage outlet are formed.The triangular net-wire of cylindrical filter cartridge is linked together with all external vertical ribs are molten mutually, form the filter core main body, and then the filter core two ends are cut the snap ring sealing that matches with it in the downhand welding, constitute complete cylindrical filter cartridge, the gap just constitutes the slit of screen pack between the baseplane of wherein adjacent two triangular net-wires.
Concrete structure of the present invention is provided by following examples and accompanying drawing.Accompanying drawing 1 is a structural representation of the present invention, also is that specification digest is with scheming.
Describe detail and the working condition that the present invention proposes in detail below in conjunction with Figure of description.
Triangular net-wire of the present invention tip cylindrical filter cartridge outwardly comprise external vertical rib 10, triangular net-wire 7, filter core main body 1, water to be filtered 3, impurity dirt 4, backwash water 5, slit 6, most advanced and sophisticated 8, snap ring 2 and sewage outlet 9.The triangular net-wire 7 of cylindrical filter cartridge be with stud 10 fixing and constitute filter core main body 1, face mutually and constitute slit 6 between two triangular net-wire 7 baseplanes, triangular net-wire 7 connects together with external vertical rib 10 is molten mutually, matching to merge with snap ring 2 then welds together.
The present invention is a kind of most advanced and sophisticated outside triangular net-wire cylindrical filter cartridge of cirque structure.Working condition is such, and there is snap ring 2 at the two ends of cylindrical filter cartridge, at a plurality of filter cores of many or the automatic cleaning and filtering interior arrangement of monotubular formula with snap rings 2 fixing or dismountings.Triangular net-wire 7 is fixing with many external vertical ribs 10, faces mutually to have constituted many slits 6 between two triangular net-wire baseplanes, and the size in these slits has just determined the filtering accuracy of whole filter.As previously mentioned, sewage 3 to be filtered is just to become clear water by slit 6 from inside to outside, and backwash water 5 to be slits 6 that ecto-entad outwards forms along the tip carry out backwash, the impurity dirt of being tackled by the slit 4 is when backwash, and the backwash wall suction nozzle of the rotation that contacts by sewage outlet 9 or with the filter core inwall is discharged.
Claims (1)
1, the most advanced and sophisticated outside triangular net-wire of a kind of annular is by the fixing cylindrical filter cartridge of external vertical rib, by triangular net-wire, external vertical rib constitutes filter core main body, slit, snap ring and sewage outlet and forms, it is characterized in that: triangular net-wire is linked together with all external vertical ribs are molten mutually, form the filter core main body, and then the filter core two ends are cut the snap ring sealing that matches with it in the downhand welding, and constituting complete cylindrical filter cartridge, the gap just constitutes the slit of screen pack between the baseplane of wherein adjacent two triangular net-wires.
