Abstract

An apparatus wherein purified water is discharged after separation of particle solid substances from the liquid at its upper part; while particle solid substance is discharged from the bottom of the device after being made to settle downwardly. More particularly, it relates to a compact settler which increases not only the efficiency of solid-liquid separation equipment but also the efficiency of settlement and of concentration equipment.

Claims

1. A SETTLER COMPRISING IN COMBINATION:

A SOLID-LIQUID SEPARATION CHAMBER HAVING AT THE UPPER PORTION THEREOF A LIQUID INLET ON ONE SIDE CHAMBER AND A LIQUID OUTLET ON THE OTHER SIDE OF SAID CHAMBER DEFINING A DIRECTION OF FLOW THEREBETWEEN, A PARTICLE SOLID SUBSTANCE SETTLEMENT MEANS IN THE LOWER PORTION OF SAID CHAMBER, A SOLID-LIQUID SEPARATION DEVICE WITHIN SAID SEPARATION CHAMBER, COMPRISING A PLURALITY OF PARALLEL PLATES HAVING UPPER AND LOWER TRANSVERSE EDGES AND FIRST AND SECOND LATERAL EDGES, SAID PARALLEL PLATES BEING ALIGNED WITH SAID UPPER AND LOWER TRANVERSE EDGES SUBSTANTIALLY PARALLEL TO THE DIRECTION OF FLOW BETWEEN SAID INLET AND SAID LIQUID OUTLET, SAID PARALLEL PLATES HAVING SAID FIRST LATERAL EDGES THEREOF FACING THE SIDE OF SAID SEPARATION CHAMBER IN WHICH IS LOCATED SAID LIQUID INLET AND SAID SECOND LATERAL EDGES THEREOF FACING THE SIDE OF SAID SEPARATION CHAMBER IN WHICH IS LOCATED SAID LIQUID OUTLET, AND SAID PARALLEL PLATES BEING INCLINED FROM THE VERTICAL AND BEING MECHANICALLY INTERCONNECTED BY A MEANS FOR MAINTAINING THE POSITIONED OF SAID PARALLEL PLATES RELATIVE TO EACH OTHER, A BAFFLE PLATE DISPOSED IN THE UPPER PORTION OF SAID SEPARATION CHAMBER BETWEEN SAID LIQUID INLET AND SAID FIRST LATERAL EDGES OF SAID PARALLEL PLATES, SAID BAFFLE PLATE BEING DISPOSED SUBSTANTIALLY AT RIGHT ANGLES TO THE PLANES OF SAID PARALLEL PLATES, A PARTICLE SOLID SUBSTANCE CONCENTRATION DEVICE COMPRISING A PLURALITY OF PARTITION PLATES DISPOSED BELOW SAID LOWER TRANSVERSE EDGES OF SAID PARALLEL PLATES, SAID PARTITION PLATES BEING PARALLEL TO EACH OTHER AND ALIGNED AT SUBSTANTIALLY RIGHT ANGLES TO THE ALIGNMENT OF SAID PARALLEL PLATES, SAID PARTITION PLATES BEING MECHANICALLY INTERCONNECTED BY A MEANS FOR MAINTAINING THE POSITION OF SAID PARTITION PLATES RELATIVE TO EACH OTHER, FIRST VIBRATION MEANS FOR VIBRATING THE PARALLEL PLATES OF SAID SOLID-LIQUID SEPARATION DEVICE, AND SECOND VIBRATION MEANS FOR VIBRATING THE PARTITION PLATES OF SAID PARTICLE SOLID SUBSTANCE CONCENTRATION DEVICE.

2. The device of claim 1, further comprising means to vibrate simultaneously both said parallel plates and said partition plates tightly unified in one body.
