Title: Heikki Oravainen: Innovator in Rock Sorting and Flotation Mechanisms
Introduction
Heikki Oravainen is a notable inventor based in Helsinki, Finland. He has made significant contributions to the fields of rock sorting and flotation mechanisms. With a total of 2 patents, his work showcases innovative methods and apparatuses that enhance efficiency in processing materials.
Latest Patents
Oravainen's latest patents include a method and apparatus for sorting pieces of rock containing quartz vein from other pieces of rock. This invention involves receiving an electric signal that represents an image of the rock to be sorted. The method determines the number of pixels in the image that have a predetermined color value indicative of quartz presence. If the number of these pixels exceeds a certain threshold, the method identifies linear forms between the quartz area and the rest of the rock. A control signal is then generated to operate a deviator device for sorting.
Another significant patent is related to a froth flotation mechanism located in a flotation cell. This invention features a directional element suspended from a hollow shaft, with vertical vanes extending above and below it. The flotation cell is designed with a cylindrical lower section, a truncated cone middle section, and a cylindrical upper section. This innovative design aims to improve the efficiency of the flotation process.
