Embodiment 1

[0019] Such as figure 1 The shown deep cone concentrator includes a cylinder, the cylinder has a cylindrical portion 8 and a cone portion 7 connected to the bottom of the cylindrical portion 8, and the inner wall of the cylindrical portion 8 is provided with a layer of wear-resistant and anti-corrosion polymer with a thickness of 2.5 mm. urea.

[0020] A method for spraying with a deep cone thickener, using a method such as figure 2 The cylinder body spraying tool shown is for spraying the inner wall of the cylinder part 8. The cylinder body spraying tool includes a bracket 1 erected on the top of the cylinder part 8, and the bracket 1 is movably hoisted with a lifting frame 6 by a sling 3. A circular aisle with an inner fence 5 and a peripheral fence 4 is arranged on the lifting frame 6. A plurality of lifting lugs are welded on the top of the peripheral fence 4 and an iron chain is worn on the first lifting lug, and the iron chain hook is hung on the spreader. 3 on the ho...

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of mining machinery manufacturing, in particular to a method for spraying a wear-resistant and anti-corrosion coating on a deep cone thickener. Background technique [0002] In the mineral processing process, it generally goes through the process of ball mill crushing, screening, flotation and tailings dumping, and the mine deep cone thickener is used as the main processing equipment for mineral dressing dumping tailings dry stacking, and the concentration effect is directly related to the final tailings dry stacking And recovery indicators for tailings water comprehensive treatment. There is a deep cone concentrator, which includes a cylinder, which is composed of a cylinder and a cone connected to the bottom of the cylinder; the diameter of the cylinder is 15 meters. The cylinder body of this deep cone concentrator has the following problems during use: 1. The pool wall and pool bottom are easily worn ...
