Canal type thickener

The invention relates to a canal type thickener, which is a canal overall. Along an ore pulp flow path, the thickener includes a canal head, a canal body and a canal tail in order. Ore pulp enters a thickening pond through a feeding port, heavy particles in the ore pulp undergo preliminary settlement in the thickening pond. The low concentration ore pulp overflowing the canal head enters the canal body to undergo further settlement. When the low concentration ore pulp flows to the canal tail, it is already in a clear water state basically and enters a clear water pond, and is discharged through a drain hole. In the invention, the thickener is changed from the traditional ''round pond'' type to the ''canal type'', thus effectively solving the problem of large floor area of the thickener. The canal structure is in linear arrangement, can be subjected to buried installation, and does not take up the volume of a concentrating mill basically. With a long canal and a large actual settlement area, the structure of the thickener can be simpler, thereby effectively reducing the production cost.
