Abstract

A kind of water process manufactures new technology with the side tank mouth of plastic inner container pressurized tank, can efficiently solve the problem of being difficult to open up side tank mouth in current plastic inner container pressurized tank manufacturing process.The technical solution adopted for the present invention to solve the technical problems is：A becket is inlaid into plastic inner container layer, prefabricated multiple screwed holes for being used to fasten on ring, the correspondence position outside glass fiber winding layer buckles a prefabricated hold-down ring again, the prefabricated screw hole of reciprocity quantity and beneficial to the groove for holding tight winding fibrous layer in the month on hold-down ring, the becket being embedded in using key screw in inner bag is tightened together with the hold-down ring being buckled in outside winding layer, thus the glass fiber winding layer opened up at side port position is tightly locked below hold-down ring, so as to ensure that cut staple winding layer is without reducing or reducing the ability that seldom whole tank body bears pressure at opening.In accompanying drawing：4. the fastening screw 11.O type circles groove 12. of 9. screw hole of bladder layer 5. glass winding layer, 6. becket, 7. screwed hole, 8. hold-down ring 10. holds tight groove in the month.

Description

The side tank mouth new technology of pressurized tank

Art

New technology is manufactured with the side tank mouth of plastic inner container pressurized tank the present invention relates to a kind of water process, belongs to composite and exists Applied technical field in purifying water treatment device.

Background technology

At present, purifying water treatment device is mostly made for containing the pressurized tank of various filtrates using glass fiber reinforced plastics composite material Make, its relatively advanced method is to make liner, also referred to as inner bag with corrosion resistant plastics, then in the outer surface ring of this inner bag The composite of oxygen tree fat and glass fibre makees winding layer to strengthen, and tank body upper and lower ends are located on tank body central axis and are set There is Inlet and outlet water tank mouth, a pressurized vessel for being used to contain various filtrates has thus been made, the tank body must be provided simultaneously with not permeable Leakage and the performance of tolerance larger fluctuation hydraulic pressure.Outputed if can be drifted out again on this pressurized vessel on the position of central axis The interface of side, dedicated for loading and drawing off filtrate, or for installing lateral Inlet and outlet water interface, will greatly promote this tank This tank mouth, is just referred to as side tank mouth by the performance of body here.

Presently known manufacturing process has the drawback that：Manufacture for manufacturing pressurized tank using plastic inner container In technique, an openning is cut out on the position of central axis once being drifted out on pressurized vessel, will twining incision Around fibre cutting, so as to destroy the overall mechanical properties of glass fiber winding, tank body will here lose and bear pressure Ability.So here it is current short slab of this tank body in manufacturing process.

The content of the invention

In order to overcome the defect for being difficult to open up side tank mouth in current plastic inner container pressurized tank manufacturing process, opening broken yarn is solved The technical barrier of pressure-bearing is unable to, the invention provides a kind of new technology, this defect is efficiently avoid.

The present invention solves the technical scheme that is used of its technical barrier：A metal is inlaid into plastic inner container layer Prefabricated multiple screwed holes for being used to fasten on ring, ring, then correspondence position outside glass fiber winding layer buckle one it is pre- The prefabricated screw hole of reciprocity quantity and beneficial to the groove for holding tight winding fibrous layer in the month on the hold-down ring made, hold-down ring, is used The becket that key screw is embedded in inner bag tightens together with the hold-down ring being buckled in outside winding layer, thus open up side port position The glass fiber winding layer at the place of putting tightly locks below hold-down ring, so as to ensure that the cut staple winding layer at opening Without reducing or reducing the ability that seldom whole tank body bears pressure.Meanwhile, it is prefabricated on the hold-down ring outside winding layer The screwed hole of closure lid or water route pipe flange and the groove for placing O-shaped O-ring seal are installed for connecting.

The beneficial effects of the invention are as follows side port is opened up on plastic inner container pressurized tank will not reduce or reduce seldom whole tank Body bears the ability of pressure.

Embodiment

Shown in accompanying drawing 1 is the water process special pressure tank body (1) alleged by the present invention, and it is with corrosion resistant plastics conduct Inner bag, adds epoxy resin to be entwined in the outer surface of inner bag with glass fibre, and the upper and lower ends of tank body central axis are provided with tank Mouth (2), the present invention is exactly to adopt new technology to have opened up side tank mouth (3) in the side of tank body, can be detained in the tank mouth of side and seal up stifled Lid (14), closure sealing is realized by seal O-ring (15) and fastening screw (16).

Shown in accompanying drawing 2, a becket (6) is inlaid into bladder layer (4), prefabricated screwed hole is being which is provided with (7)；Button plus a hold-down ring (8) on the outer surface of glass winding layer (5) are prefabricated screw hole (9) on the hold-down ring (8) With hold tight groove (12) in the month；With fastening screw (10) the compression of becket (6) and glass winding layer (5) outside in bladder layer (4) Ring (8) is locked together, during locking, glass fibre and epoxy resin be just pressed on hold-down ring (8) hold in the month it is tight recessed In groove (12), be difficult to be drawn out convex stupefied is formd.So it is achieved that the glass winding layer (5) at side opening is tightly locked Tightly between bladder layer (4) and hold-down ring (8) so that the bearing capacity of tank body herein is not lowered or reduced seldom.

Accompanying drawing 3 shows the concrete structure for how realizing closure opening, on hold-down ring (8) it is prefabricated be used for it is tight The screwed hole (13) of sealing blanking cover (14) and the O-ring groove (11) for embedding sealing O-ring (15), use fastening screw (16) closure lid (14) and seal O-ring (15) are fastened with hold-down ring (8), is achieved that the closure of side tank mouth (3).When So, installation inlet and outlet pipe can also be connected in side tank mouth (3) using screwed hole (13).
