Title: Erkka Nieminen: Innovator in Flotation Cell Technology
Introduction
Erkka Nieminen is a notable inventor based in Tampere, Finland. He has made significant contributions to the field of flotation cell technology, holding a total of 4 patents. His innovative designs focus on improving the efficiency of fiber suspension flows in flotation cells.
Latest Patents
Nieminen's latest patents include an injector for flotation cells. This injector features a feed channel designed to deliver a fiber suspension flow into the flotation cell. It incorporates a flow distribution element that divides the fiber suspension flow into partial flows. Additionally, a mixing apparatus is included to mix air with the fiber suspension flow, with at least one air input point for drawing air into the injector. The arrangement of these components ensures that the flow direction of the fiber suspension in the feed channel is opposite to that of the flow through the distribution element and mixing apparatus.
Another significant patent is the flotation cell injector itself. This injector consists of a feed pipe for introducing a fiber suspension flow into the flotation cell. It also includes a mixing apparatus for integrating air into the fiber suspension flow, along with an air feed connection positioned before the mixing apparatus. The injector is equipped with a nozzle section that features an aperture plate with apertures and nozzles, allowing air to flow into the spaces between the nozzles and into the mixing apparatus.
