Abstract
The present invention discloses a barrel type filter core with an outward circular ring shape triangular net thread point, which is composed of a barrel type filter core (column) 1, a retainer ring 2, a slit 6, a triangular net thread 7, an inner vertical rib 10 and a sewage discharge opening 9. The triangular net thread 7 of the filter core and the inner vertical rib 10 are melted and connected together, and simultaneously are matched and welded with the retainer ring 2 together to form an 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 annular triangular net-wire tip cylindrical filter cartridge of being made up of cylindrical filter cartridge (post), snap ring, slit, triangular net-wire, interior stud, sewage outlet outwardly.Snap ring is being fixed at the two ends of cylindrical filter cartridge, and triangular net-wire is fixing with interior stud, faces mutually between two triangular net-wire planes to constitute the slit, and triangular net-wire connects together with the ring muscle is molten mutually, and matching to merge with snap ring simultaneously again welds together.
Concrete structure of the present invention is provided by following examples and accompanying drawing.Accompanying drawing 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 comprises cylindrical filter cartridge (post) 1, snap ring 2, water to be filtered 3, impurity dirt 4, backwash water 5, slit 6, triangular net-wire 7, tip 8, sewage outlet 9, interior stud 10.Snap ring 2 is being fixed at the two ends of cylindrical filter cartridge (post), triangular net-wire 7 is fixing with stud 10, face formation slit 6 between two triangular net-wire 7 baseplanes mutually, triangular net-wire 7 connects together with interior stud 10 is molten mutually, and matching to merge with snap ring 2 simultaneously again 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 1, and is fixing with snap rings 2 at a plurality of filter cores of many or the automatic cleaning and filtering interior arrangement of monotubular formula.Many triangular net-wires 7 are to fix with interior stud 10, face 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 cylindrical filter cartridge of an annular, form by cylindrical filter cartridge (post), snap ring, slit, triangular net-wire, interior stud, sewage outlet, it is characterized in that: snap ring is being fixed at the two ends of cylindrical filter cartridge, triangular net-wire is fixing with interior stud, face mutually between two triangular net-wire baseplanes and constitute the slit, triangular net-wire connects together with interior stud is molten mutually, and matching to merge with snap ring simultaneously again welds together.
