Abstract
This invention discloses a method for producing pressure container for water treatment. The method comprises: producing each section of the hollow lining of the pressure container by using thermoplastic material and traditional technique, adhering the sections by adhesive to form the hollow lining, and winding the outer surface of the lining with glass fibers.
Description
Technical field:
The present invention relates to pressurized vessel in a kind of water treating equipment and preparation method thereof, belong to water treating equipment pressure vessel technology field.
Background technology:
A large amount of applying pressure containers in the water treating equipment, normally used pressurized vessel generally comprises the liner container of hollow, and the liner outside is coated with the rigidity of strengthening liner with glass fibre.Make in the existing Technology at the liner of hollow, a kind of bonding technology of stepwise process of using is arranged: adopt thermosetting resin and reinforcing glass fiber, with hand stick with paste or method such as injection with each section moulding, then and the screw thread mouth of moulding in advance assemble the liner that bonding one-tenth is complete.Generally composition is bigger by hand for this technique for sticking, at the bottom of the production efficiency and be not easy controlling quality, the leftover bits that produce are many, environmental pollution is also bigger, and the pressure change liner when using with pressurized vessel can produce and expand and contraction, because the fragility of material itself, after one section of work the interface cracking often taking place, causes container to lose efficacy.Problem in the above-mentioned technology never is resolved effectively.
Summary of the invention:
The manufacture method of pressure vessel for water treatment of the present invention comprises that step is as follows:
Adopt thermoplastic material and traditional manufacturing technique to make each section of the hollow liner of decomposition pressure container respectively;
Sticking with glue agent bonds together described each section and forms the liner of hollow;
Be wrapped in the outside of liner with glass fibre.
Each section of described hollow liner comprises straight length, upper and lower seal head section, and be positioned at or the hickey at lower cover section middle part, described straight length adopts the pipeline extrusion technology.
Described straight length is one; Described thermoplastic material is ABS or UPVC, described hickey and last or lower cover is one-body molded.
A kind of pressure vessel for water treatment comprises liner, screw thread mouth, and be coated on liner outside glass layer, it is characterized in that described liner and screw thread mouth are made by thermoplastic material.Described thermoplastic material is ABS or UPVC.
Advantage of the present invention:
Owing to adopted thermoplastic material to make each section that forms liner respectively in aforesaid method, the liner of making is difficult for cracking at bonding position, has improved the quality of product.Because each section of liner made respectively, can use sophisticated prior art, help producing in batches and improved production efficiency; This mode of production of the present invention technology has compared to existing technology significantly reduced leftover bits, not only saves cost, also helps environmental protection.
Embodiment:
Accompanying drawing 1 is an embodiment sectional view of pressure vessel for water treatment of the present invention.
The sectional structure chart that has shown a container of the present invention among Fig. 1, wherein 1 is integral container, the 2nd, the middle straight pipeline section of container inside lining, the 3rd, the upper and lower seal head section of liner, the 4th, the bonding plane on liner straight tube 2 and the liner between the lower cover, the 5th, the liner screw thread mouth, the 6th, the bonding plane of screw thread mouth 5 and upper cover 3, the 7th, be coated on the outer glass layer of liner.Making method is, the straight length 2 of liner, go up lower cover 3, and screw thread mouth 5 all use thermoplastic material such as ABS or UPVC pre-formed respectively, again each several part is carried out the complete liner container of bonding formation, use existing glass fibre coating equipment to coat layer of glass layer 7 in the integral lining outside then.
Above-mentioned last lower cover can also can be preformed in screw thread mouth with respectively machine-shaping of prior art with one of them end socket, the liner straight length can be with the moulding of existing pipeline extruding technology, carries out common bonding then.After bonding, use traditional method and apparatus to coat layer of glass, make the integral body of water treatment vessels in the outside of liner.
The present invention has been owing to adopted thermoplastic material to make each section of liner, enhances productivity greatly and produces in batches thereby more help mechanical workout; Comparing existing segmental machining method more saves material and helps environmental protection; Prevent the phenomenon of rupture of the abutting edge that causes because of the continuous pressure change of liner, improved quality product.
The concrete sectional making equipment that the present invention relates to can use traditional prior art.
Protection scope of the present invention is limited by claims.
