Wear-resistant structure for laterite nickel ore autoclave

Abstract

The present application discloses a wear-resistant structure for a laterite nickel ore autoclave, comprising an autoclave body, an insulating sleeve, and a wear-resistant plate. An accommodating cavity is formed in the autoclave body, and a first mounting slot is formed on the inner wall of the accommodating cavity. The insulating sleeve is embedded in the first mounting slot, and a second mounting slot is formed on the insulating sleeve. The wear-resistant plate is embedded in the second mounting slot, wherein the insulating sleeve blocks the flow of electrical charges between the wear-resistant plate and the autoclave body. The insulating sleeve is embedded in the first mounting slot, and the wear-resistant plate is embedded in the second mounting slot, so that the wear-resistant plate can be fixed inside the autoclave body, thereby improving the wear resistance of a stirring area by means of the wear-resistant plate. In addition, since the insulating sleeve blocks the flow of the electrical charges between the wear-resistant plate and the autoclave body, the galvanic effect between the wear-resistant plate and the autoclave body can be prevented, avoiding accelerated corrosion of the autoclave body caused by the galvanic effect from different types of metals, thereby prolonging the service life of the autoclave.

Description

Autoclave wear-resistant structure for laterite nickel ore TECHNICAL FIELD

[0001] The present application relates to the field of laterite nickel ore smelting, in particular to an autoclave wear-resistant structure for laterite nickel ore. BACKGROUND

[0002] The autoclave is a commonly used equipment for high-pressure leaching of laterite nickel ore in a wet smelting process. The reaction in the autoclave is complex, with high pressure, high temperature, and high acidity.

[0003] Currently, the stirring area of the autoclave is prone to wear, which affects the safety and use of the autoclave and requires regular inspection and repair, resulting in high maintenance costs. Chinese patent CN211988621U discloses a wear-resistant protective plate for a pressurized kettle. Since the stirring area of the pressurized kettle is the most easily worn part, a wear-resistant plate is laid on the inner wall of the kettle body in the stirring area to improve the wear resistance of the stirring area of the pressurized kettle. However, since the wear-resistant plate and the metal of the pressurized kettle are different, a galvanic effect is easily generated between them, causing the kettle body of the pressurized kettle to be easily chemically corroded.

[0004] Therefore, it is a technical problem to be solved that the galvanic effect caused by the wear-resistant plate accelerates the corrosion rate of the kettle body.

[0005] SUMMARY

[0006] The present application aims to overcome the above technical deficiencies and provides an autoclave wear-resistant structure for laterite nickel ore, which solves the technical problem of the galvanic effect caused by the wear-resistant plate accelerating the corrosion rate of the kettle body in the conventional technology.

DETAILED DESCRIPTION

[0026] In order to make the purposes, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and not used to limit the present application.

[0027] It should be noted that the high-pressure autoclave wear-resistant structure for laterite nickel ore described in the present application is used in, but not limited to, the high-pressure autoclave for laterite nickel ore and the like. For the convenience of description, in the present application, the high-pressure autoclave wear-resistant structure for laterite nickel ore is only taken as an example to be applied to the high-pressure autoclave for laterite nickel ore for description, and the principle of the high-pressure autoclave wear-resistant structure for laterite nickel ore applied to other types of equipment is substantially the same as that applied to the high-pressure autoclave for laterite nickel ore, which is not described here.

[0028] Please refer to FIG. 1, which is a structural schematic diagram of the high-pressure autoclave wear-resistant structure for laterite nickel ore in an embodiment of the present application. The high-pressure autoclave wear-resistant structure for laterite nickel ore comprises an autoclave body 100, an insulation sleeve 200 and a wear-resistant plate 300.

At the same time, since the insulation sleeve 200 can block the charge flow between the wear-resistant plate 300 and the autoclave body 100, the original battery effect between the wear-resistant plate 300 and the autoclave body 100 can be blocked, thereby avoiding the problem of accelerated corrosion of the autoclave body 100 caused by the original battery effect of different types of metals, and prolonging the service life of the high-pressure autoclave.

[0030] In some embodiments, the wear-resistant plate 300 comprises a plurality of unit parts 310, and the plurality of unit parts 310 are sequentially spliced end to end and embedded in the second mounting groove 210.

[0031] In the present embodiment, the wear-resistant plate 300 is sequentially spliced end to end by a plurality of unit parts 310, and when the wear-resistant plate 300 is installed, the unit parts 310 can be embedded in the second mounting groove 210 one by one. When the wear-resistant plate 300 is disassembled, the unit parts 310 can be disassembled from the second mounting groove 210 one by one.

[0032] In some embodiments, the unit part 310 is provided with a slot 311 at one end, and a plug 312 at the other end, and the plug 312 of the unit part 310 is embedded in the slot 311 of the adjacent unit part 310.

[0033] In the embodiment, the unit part 310 is provided with a plug and a slot, and the adjacent unit parts 310 are connected by the plug 312 and the slot 311, so that the unit parts 310 can be accurately connected to each other.

[0036] In some embodiments, the unit part 310 is a titanium alloy unit part 310.

[0037] In the embodiment, the unit part 310 is a titanium alloy unit part 310, so that the unit part 310 has sufficient wear resistance.

[0039] In the embodiment, the insulating sleeve 200 is partially embedded in the annular groove 130, so that the insulating sleeve 200 can be more stably mounted in the kettle body 100.

[0041] In the embodiment, the insulating sleeve 200 and the kettle body 100 are connected by the bolts passing through the communication holes 140 and screwing the screw holes 220, so that the insulating sleeve 200 can be prevented from being separated from the annular groove 130 and the first mounting groove 120.

[0042] In some embodiments, the insulating sleeve 200 is a plastic insulating sleeve 200.

[0043] In the embodiment, the insulating sleeve 200 is made of plastic material, and has sufficient structural strength and corrosion resistance.

The corrosion speed of the autoclave body 100 can be slowed down by sacrificing the anode block 400.

In addition, since the insulating sleeve 200 can block the charge flow between the wear-resistant plate 300 and the autoclave body 100, the original battery effect between the wear-resistant plate 300 and the autoclave body 100 can be blocked, and the problem of accelerated corrosion of the autoclave body due to the original battery effect caused by different types of metals can be avoided, thereby prolonging the service life of the autoclave.
