Description

A kind of corrosion-resistant leaching retort

[technical field]

The utility model relates to a kind of leaching retort that the contained metallic element process of various breezes is leached in the acid dissolving, especially a kind of corrosion-resistant leaching retort of being used for.

[background technology]

In hydrometallurgy process, concentrate commonly used or calcining are produced as raw material, and taking agitation leach is an important procedure of this production process.And the used major equipment of this operation leaches retort exactly.Owing in leaching process, leach in order to strengthen solid, in strongly acidic solution, carry out heated and stirred usually, therefore leaching retort and the accessory thereof that uses should possess abilities such as wear-resistant, that the burn into of anti-strong acid is heat-resisting simultaneously.

Existing more common leaching retort mostly is metal (carbon steel) shell, inside lining anti-corrosive material (as fiber glass epoxy, acid-proof ceramic tile or plate etc.), the retort ubiquity heaviness of the type, inside lining anti-corrosive material cracky, heating tube be corroded breakage, need deficiency such as running check maintenance.

[utility model content]

It is a kind of simple and reasonable that technical problem to be solved in the utility model is to provide, and the corrosion-resistant leaching retort that cost is low is not only wear-resisting, corrosion-resistant but also heat-resisting, easy to operate, the utilising efficiency height.

The technical solution of the utility model is: a kind of corrosion-resistant leaching retort, comprise with tank body and tank body loam cake, described tank body is a round shape, described tank body loam cake is the circle that cuts into two halves, its surface has manhole, center rabbling door, exhausting hole, and direct supply type steam heating tube, feeding liquid pipe and thermocouple sheath are installed; Wherein said direct supply type steam heating tube is processed by double-deck polypropylene tube.

As the further improvement of such scheme, described inner tank wall evenly adds four flow-stopping plates, and the triangular support muscle all is equipped with in every described flow-stopping plate side.

As the further improvement of such scheme, described tank base forms conical cylinder by installing the slope base plate additional, and the two ends of described slope base plate are separately fixed on described inner tank wall and the tank bottom, and its back side of panel is fixed with bearing rib.

As the further improvement of such scheme, described inner tank wall evenly is provided with polylith Liquid level scale plate.

Advantage of the present utility model is:

1. the utility model tank body and tank body loam cake select for use polypropylene material to make, and have fundamentally solved anticorrosion problem, and have had stronger wear-resisting and temperature resistant capability.

2. this leaching retort is made into conical cylinder shape with the tank body bottom when processing and fabricating, and having solved straight barrel shape can not disposable problem of putting clean reacting slurry fully.

3. install 4 flow-stopping plates additional in inner tank wall,, when having improved mixing effect, also improved the splendid attire material coefficient of tank body to avoid forming whirlpool.

4. install the Liquid level scale plate additional in inner tank wall, can make the very visual and accurate volume that observes each input reaction solution of operator.

5. install the effective double-deck polypropylene pipe of direct supply type steam heating additional and make, not only corrosion-resistant, but also high temperature resistant anti-softening.
