Hydrocyclone Conduit
View pageUS Patent:
50965875, Mar 17, 1992
Filed:
Jul 31, 1990
Appl. No.:
7/562208
Inventors:
Ernest J. Charette - Taunton MA
Assignee:
Bird Escher Wyss - Mansfield MA
International Classification:
B01D 2126
US Classification:
2105122
Abstract:
Hydrocyclone separators of the type used to separate contaminants from pulp suspensions in paper mills are connected to feed, accept, and reject conduits using a conduit apparatus in which both feed and accept portions are preferably bent from smooth plate material. The feed and accept portions preferably include generally flat surfaces through which holes are drilled for making connections to the feed and accept nozzles of the hydrocyclones. The smooth plate material eliminates the tendency of pulp to build up on the conduit walls and in the nozzles, thereby avoiding the problems that can occur when such build ups break loose. The nozzles of the hydrocyclones are preferably attached by placing a resilient sealing member around the circumference of the nozzle, and inserting the nozzle into an aperture formed in a generally flat wall of the conduit until the sealing member engages the inside wall of the aperture.
Pressure Knotter Screening Apparatus

50788787, Jan 7, 1992
Filed:
Jul 7, 1989
Appl. No.:
7/377798
Inventors:
Ernest J. Charette - Taunton MA
Assignee:
Bird Escher Wyss - Mansfield MA
International Classification:
D21D 500
US Classification:
210408
Abstract:
A rotor is disposed concentrically within a cylindrical screen. The rotor carries a plurality of blades in close proximity to the screen to produce hydrodynamic pulses opposing fluid flow to clear the screen. Each blade includes a first portion affixed to the rotor, this first portion including an inclined face and a substantially raidally extending face. A second portion of the blade is removably affixed to the radially extending face of the first portion. The removable second portion extends radially beyond the first portion. After the removable portion has become worn from extended use, it can be removed and replaced with a new second portion. In a preferred embodiment, the thickness of the second portion of the blade is equal to or greater than the diameter of holes in the screen. It is also preferred that the length of the second blade portion extending beyond the first portion be greater than the diameter of holes in the screen. In this embodiment the length of the projection of the inclined face of the first portion should be greater than the length of the radially extending face.
