The invention discloses a spraying method of a deep cone thickener. A barrel spraying special tool is used to spray the inner wall of a cylinder part. The spraying method of the deep cone thickener comprises the following operating steps of falling an elevating scaffold to the bottom part of the cylinder part, and spraying high wear-resisting anticorrosion polyurea on the inner wall of the cylinder part through an operator standing on an annular aisle; lifting the elevating scaffold to a spraying height, and spraying the high wear-resisting anticorrosion polyurea on the inner wall of the cylinder part through the spraying tool used by an operator standing on an annular aisle until the inner wall of the cylinder part is fully sprayed with a wear-resisting anticorrosion polyurea coating; repeating the steps until the thickness of the wear-resisting anticorrosion polyurea coating of the inner wall of the cylinder part is 2.5mm-3.5mm. Compared with the prior art, the spraying method of the deep cone thickener can solve the problems that the existing deep cone thickener is short in service life and high in cost.
