Abstract
Abstract Sedimentation apparatus for continuously treating a liquid suspension to separate clarified liquid from sediment. The apparatus comprises a housing and a plurality of inclined parallel plates within the housing which provide parallel inclined passages for the passage of the liquid suspension therebetween. An inlet means is provided for delivering the liquid suspension to all of the passages, and the plates are mounted with a yieldable connection relative to the housing. A vibrator means for the plates is provided which vibrates the plates with oscillations occurring substantially only in the direction of inclination of the plates so as to prevent deposits of sediment on the plates but without disturbing the sedimentation. In addition, means is provided for receiving the clarified liquid and also the sediment which are discharged from the passages.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
129 words
A SEDIMENTATION APPARATUS FOR CONTINUOUSLY TREATING A LIQUID SUSPENSION TO SEPARATE CLARIFIED LIQUID FROM SEDIMENT COMPRISING: A HOUSING, A PLURALITY OF INCLINED PARALLEL PLATE MEANS WITHIN SAID HOUSING PROVIDING A PLURALITY OF PARALLEL INCLINED PASSAGES FOR THE PASSAGE OF THE LIQUID SUSPENSION THEREBETWEEN, INLET MEANS FOR DELIVERING SAID LIQUID SUSPENSION TO ALL SAID PASSAGES, MEANS FOR MOUNTING SAID PLATE MEANS IN YIELDABLE CONNECTION RELATIVE TO SAID HOUSING, AT LEAST ONE VIBRATOR MEANS, MEANS FOR CONNECTING SAID VIBRATOR MEANS TO SAID PLATE MEANS FOR VIBRATING SAID PLATE MEANS WITH SUBSTANTIALLY ONLY OSCILLATIONS IN THE DIRECTION OF INCLINATION OF SAID PLATE MEANS FOR PREVENTING DEPOSITS OF SEDIMENT ON SAID PLATE MEANS WITHOUT DISTURBING THE SEDIMANTATION, AND FIRST AND SECOND MEANS FOR RECEIVING, RESPECTIVELY, CLARIFIED LIQUID AND SEDIMENT DISCHARGED FROM SAID PASSAGES.
Claim 2
Dependent Claim
129 words
A SEDIMENTATION APPARATUS FOR CONTINUOUSLY TREATING A LIQUID SUSPENSION TO SEPARATE CLARIFIED LIQUID FROM SEDIMENT COMPRISING: A HOUSING, A PLURALITY OF INCLINED PARALLEL PLATE MEANS WITHIN SAID HOUSING PROVIDING A PLURALITY OF PARALLEL INCLINED PASSAGES FOR THE PASSAGE OF THE LIQUID SUSPENSION THEREBETWEEN, INLET MEANS FOR DELIVERING SAID LIQUID SUSPENSION TO ALL SAID PASSAGES, MEANS FOR MOUNTING SAID PLATE MEANS IN YIELDABLE CONNECTION RELATIVE TO SAID HOUSING, AT LEAST ONE VIBRATOR MEANS, MEANS FOR CONNECTING SAID VIBRATOR MEANS TO SAID PLATE MEANS FOR VIBRATING SAID PLATE MEANS WITH SUBSTANTIALLY ONLY OSCILLATIONS IN THE DIRECTION OF INCLINATION OF SAID PLATE MEANS FOR PREVENTING DEPOSITS OF SEDIMENT ON SAID PLATE MEANS WITHOUT DISTURBING THE SEDIMANTATION, AND FIRST AND SECOND MEANS FOR RECEIVING, RESPECTIVELY, CLARIFIED LIQUID AND SEDIMENT DISCHARGED FROM SAID PASSAGES.
Claim 3
Dependent Claim
23 words
An apparatus as claimed in claim 1 wherein said means for mounting said plate means consists of resilient means supporting said plate means.
Claim 4
Dependent Claim
23 words
An apparatus as claimed in claim 1 wherein said means for mounting said plate means consists of resilient means suspending said plate means.
Claim 5
Dependent Claim
150 words
A sedimentation apparatus for continuously treating a liquid suspension to separate clarified liquid from sediment comprising a housing a plurality of inclined parallel plate means within said housing providing a plurality of parallel inclined passages for the suspension therebetween, means for interconnecting a plurality of said plate means to form a compound package, inlet means for the suspension for delivering said suspension to all said passages, means for mounting said said compound package of plate means in yieldable connection relative to said housing, at least one vibrator means, means for connecting said vibrator means to said plate means package for vibrating said plate means in said plate means package with substantially only oscillations in the direction of inclination of said plate means for preventing deposits of sediment on said plate means without disturbing the sedimentation per se, and separate means for receiving clarified liquid and sediment discharged from said passages.
