First kind: burrow on filter screen with rivet riveting meeting, though all cling with glue at the hole, when glue cleaned with acid at equipment, glue all can melt, thereby can ftracture in the place of filter screen punching.
Second kind: with glue filter screen is directly clung, in the assembling framework of packing into then, the filter screen surrounding edge of playing glue is along in fact remaining exposed glue position.In fact this way exists the same defective with first kind, though the sticking intensity of glue is very big, gluing after all place still is exposed to outer, and it still is afraid of acid, and chance acid is then decomposed, and falls apart thereby come unstuck.Therefore, existing disc can not be met the need of market.
Summary of the invention
The objective of the invention is that existing glue melts when equipment cleans with acid with disc in the market rotary disc filter, the problem that filter screen ftractures and comes unstuck and fall apart, the rotary disc filter that propose a kind of structure consolidation, is difficult for coming unstuck is used disc.Adopt the setting of injection moulding bound edge, make glue not contact, be injection-moulded in the working of plastics, be exposed to the outer problem that corrosion is decomposed in acid of meeting easily with regard to thorough solution glue like this with water or pickle.
Technical scheme of the present invention is:
A kind of rotary disc filter is used disc; It comprises a plurality of fan-shaped discs; Each fan-shaped disc includes a slice filter screen and the filter screen fixed mount that has many slots at least, and the periphery of described filter screen is the injection moulding screen frame, and the filter screen that has the injection moulding screen frame is installed in the corresponding slot of filter screen fixed mount.
Filter screen of the present invention is fan-shaped stainless (steel) wire or polyester fiber net, and areola is the 5-15 micron.
The areola of filter screen of the present invention is 10 microns.
Filter screen fixed mount of the present invention comprises upper frame, left frame and correct frame, and described upper frame, left frame and correct frame all have a plurality of slots..
The two ends of upper frame of the present invention, left frame and correct frame are equipped with bolt hole, and left frame and correct frame are the L type.
Beneficial effect of the present invention:
The injection moulding screen frame of disc of the present invention adopts disposable Shooting Technique to make; And the monolithic filter screen all can be dismantled separately; And need not all disc filter screens all be removed to change the disc filter screen that damages in certain piece running wherein after the dismounting again; So both strengthen the intensity of disc filter screen, reduced disc screen replacing cost and labour intensity again.A circumference has 12 independently fan-shaped discs, and each fan-shaped disc is made up of the independently fan-shaped filter screen of two fritters, and every independently fan-shaped filter screen all can change separately, and every fan-shaped filter screen both can adopt stainless steel can adopt the polyester fiber material.
The present invention be filter screen and the fan-shaped screen frame of steel with special glue after; Send into injection machine again, it is carried out fan-shaped periphery carry out injection moulding bound edge formation injection moulding screen frame, such one can finalize the design to filter screen; Two can avoid beating glue the position be exposed to outside; And then the disc filter screen after the injection moulding bound edge typing inserted have on " L " shape injection moulding housing of dual slot, thus, make water and cleaning weak acid in glue and the pond bump forever less than.Avoided glue to be afraid of the fact of acid.The present invention has that cost is low, the advantage of light and handy practicality, under the real damaged situation of filter screen, only needs to change the injection moulding screen frame of filter screen and one, and ten minutes is easy.
