Definitions

  • N 141770 1 1 pp 0 ABSTRACT A method of manufacturing high quality zinc powder in an independent grouping of small modular components, each having a combination oven and condensation chamber.
  • a device in the condensation chamber acts as a safety valve which eliminates the risk of explosion when an abnormal reaction occurs inside the chamber.
  • a device in the condensation chamber functions as a cleanser for zinc oxide to control not very violent abnormal reactions.
  • a filtering device can be installed between the steaming retort or crucible and the condensation chamber which eliminates impurities in the zinc utilized.
  • a primary object of the present invention is the provision of an installation for manufacturing high quality zinc powder at a very low cost.
  • a further object of the present invention is the provision of a process for eliminating impurities if zinc containing the same is utilized.
  • a further object of the present invention is the provision of a process employing a safety device to prevent explosions would would destroy the installation.
  • a still further object is the provision of a process which allows for eliminating a very high percentage of zinc oxide (ZnO) in the zinc powder produced, whereby it is possible to compete advantageously with any installation. This process prevents the operation of the safety device when an abnormal, not very violent reaction, occurs in the condensation chamber.
  • ZnO zinc oxide
  • Minimum production of each modular component is in excess of 1,000 kilos daily.
  • the zinc is melted and subsequently loaded into a retort or crucible, the zinc then being vaporized in the retort or crucible proper.
  • This vapor passes through a device for eliminating impurities and then to a condensation chamber. Vapor in this chamber is deposited as zinc powder in receptacles. These receptacles are removed as they are filled, and replaced by empty receptacles. Later the zinc powder obtained is put through a sieve. When the zinc in the retort or crucible is almost consumed, the process is initiated again without interrupting its continuity.
  • FIG. 2 is a perspective view of a retort or crucible in which zinc is vaporized.
  • FIG. 3 is a perspective view of a chamber for eliminating impurities from the zinc.
  • FIG. 4 is a perspective view of a chamber where zinc is condensed and of the deposits where the product is collected.
  • FIG. 5 is a partially sectioned schematic view of one of the modular components of the installation.
  • FIG. 6 is a schematic view of the same component from another point located in relation to the above.
  • FIG. 7 is a view similar to that shown in FIG. 6 but in which the modular component has no crucible for melting the zinc.
  • a melting crucible l for melting the zinc is situated inside an oven 9 having a chimney 10, but farther from burners (not shown) than a retort or crucible 2, where the zinc is vaporized.
  • the temperature in the vicinity of the retort 2 is in excess of the boiling point of the zinc. 2 is an addition to the retort, and 2" is a retort cover.
  • the zinc need not be melted in the modular component shown, but may arrive at the retort 2, already melted, in order to continue the process from there.
  • the zinc metal utilized contains few impurities it requires no device such as chamber 3, and in this case the zinc vapor passes directly from the vaporizing retort 2, to condensation chamber 4.
  • Pure zinc vapor passes to the condensation chamber 4, settles in powdered form in each of the deposits or receptacles 5. These deposits 5 are removed as they are filled, and are replaced by empty receptacles so that periodic collection of zinc powder may continue.
  • a purging device 7 is fitted in the lower part of the chamber 4 to control and expel the zinc oxide resulting in chamber 4, and when a not very violent abnormal reaction occurs in chamber 4, device 7 controls the reaction and prevents device 6 from operating.
  • Process for producing high quality zinc powder comprising:
