Connection device for connecting a hydrocyclone

A connection device for connecting a hydrocyclone to a distribution and collection device for addition or removal of liquids, in which the distribution and collection device includes connection openings through which the addition or removal of the liquid occurs during operation of the hydrocyclone, the connection device comprising:

• a pipe piece having an insertion side structured and arranged to be insertable through one of the connection openings into the distribution and collection device;
• said insertion side comprising a circumferential groove and a radial protrusion positioned adjacent said circumferential groove;
• said radial protrusion having an outer diameter smaller than an inner diameter of the one connection opening and being structured to remain within the distribution and collection device;
• a ring-shaped seal, structured and arranged to extend from an exterior of the distribution and collection device to an interior of the distribution and collection device, having an outer diameter greater that the inner diameter of the one connection opening;
• said ring-shaped seal being positionable in a tensioned state in said circumferential groove;
• a pressure component positioned outside of the distribution and collection device that is structured and arranged exert a force to axially compress said ring-shaped seal.

• a pressure component arranged to axially compress said ring-shaped seal;
• and
• a forcing nut arranged to axially compress said pressure component,
• wherein said pressure component is formed as a part of said forcing nut.

A process for connecting a distribution and collection device to a hydrocyclone, in which the distribution and collection device includes a number of connection openings, the process comprising:

• inserting an insertion side of a pipe piece through one of the connection openings into the distribution and collection device, wherein the insertion side of the pipe piece includes a circumferential groove and a radial protrusion, positioned adjacent the circumferential groove, that has an outer diameter smaller than an inner diameter of the one connection opening;
• positioning a ring-shaped seal onto an edge forming the one connection opening, wherein the ring-shaped seal, which is positioned to extend from an exterior of the distribution and collection device to an interior of the distribution and collection device, has an outer diameter greater that the inner diameter of the one connection opening;
• and
• positioning the ring-shaped seal into the circumferential groove in a tensioned state.
