Description
Technical field
Technical field is washed the invention belongs to extrusion die erosion, returning for dilution sodium hydroxide is lost more particularly, to a kind of mould
Receipts system.
Background technology
In the big production of modernization of extruding factory, mould is to realizing that whole extrusion process has highly important meaning.For
The life-span of mould is improved, every country to mold use and maintenance has carried out extensive research.Traditional extrusion die erosion
Washing method is that mould is immersed into sodium hydroxide solution, is dissolved aluminum metal using sodium hydroxide solution so that mould becomes
Obtain totally, conveniently reuse.But the aluminium of dissolving can be enriched with sodium hydroxide solution quickly, so continuing to dissolve more
During aluminium, its solvability declines until completely losing, therefore must be replaced as frequently as and be discharged using this erosion washing method quickly
Fall non-serviceable sodium hydroxide solution, very big pollution is caused to environment.
The content of the invention
The technical problems to be solved by the invention, which are to provide one kind, can effectively reduce production cost, reduce environmental pollution
Mould loses the recovery system of dilution sodium hydroxide.
In order to solve the above technical problems, the technical solution adopted by the present invention is：
A kind of mould loses the recovery system of dilution sodium hydroxide, including storage container, boils mold container and reaction tank, storage container
The bottom of side is provided with blowoff valve, and the opposite side of storage container is connected by pipeline I with boiling the inlet of mold container, boils mold container
Top cover be provided with blast pipe, reaction tank is in open-topped hollow structure, and stirring vane is provided with reaction tank, stirring vane
Shaft end is driven after passing through reaction tank by motor, and the inlet of reaction tank side passes through pipeline II and the liquid outlet for boiling mold container
Connection, pipeline II is provided with delivery pump I, reaction tank above pipeline II is provided with air inlet pipe, and reaction tank opposite side goes out
Liquid mouthful is connected by pipeline III with the inlet at the top of storage container, and pipeline III is provided with delivery pump II.
The top of the storage container is provided with density tester.
The storage container is cylindrical iron container.
The top cover for boiling mold container, which is hingedly fixed in, to be boiled on mold container.
It is an advantage of the invention that：The recovery system use of the present invention will contain NaAlO2Sodium hydroxide solution be converted into can
The sodium hydroxide solution and the dry mud of aluminum hydroxide precipitation reused, the consumption of caustic soda reduces more than 80%, removes the need for
The problem of the discarded sodium hydroxide solution of processing, reduces enterprise into production cost, improves the environment of surrounding, more energy-conserving and environment-protective,
And it is simple in construction, it is easy to efficiency is washed in operational control, the erosion for effectively increasing extrusion die.
Brief description of the drawings
The present invention is described in further detail with reference to the accompanying drawings and detailed description.
Fig. 1 is the structural representation of the present invention.
