Description
Technical Field
The utility model belongs to the technical field of hydrometallurgy pressure leaching, and particularly relates to a device for prolonging the service life of a discharge valve on an autoclave.
Background
The pressure leaching process is one of metallurgical technologies in wet smelting, has the advantages of high leaching efficiency, low cost, strong raw material adaptability and the like, and is widely applied to the wet smelting of nickel sulfide concentrate. The process comprises the following steps: feeding the ore pulp raw material into a pressure kettle, introducing oxygen and steam into the pressure kettle, stirring in the high-temperature and high-pressure kettle, and discharging the feed liquid through a discharge valve after full reaction. Because the pressure leaching process is continuous, the pressure difference between the pressure kettle and the discharge valve and the pressure difference between the pressure kettle and the pressure kettle are large during discharging, the flow speed of ore pulp is too high, and the ore pulp contains metal solid particles, so that the service life of the discharge valve is shortened under the high-speed flushing of the ore pulp with the metal solid particles, the discharge valve is damaged, the subsequent maintenance cost is increased, and the subsequent production is affected.
Disclosure of Invention
The utility model aims to provide a device for prolonging the service life of a discharge valve on an autoclave, which aims to solve the problem that the discharge valve is easy to damage when pulp with metal solid particles is flushed at a high speed.
The technical scheme of the utility model is as follows: the device for prolonging the service life of the discharge valve on the pressurized kettle comprises a barrel body, wherein a barrel cover is arranged at the top of the barrel body, a filter screen is arranged in the barrel body, a feed pipe and a discharge pipe are arranged on the barrel body, and the feed pipe and the discharge pipe are respectively positioned at two sides of the filter screen; the discharge end of the autoclave is connected with the feed pipe, and the discharge valve is arranged on the discharge pipe.
Further, the inlet pipe is located staving lower part, and the discharging pipe is located staving upper portion.
Further, the filter screen is arranged in a cylindrical shape, so that the filtering area can be increased; a certain gap is arranged between the filter screen and the inner wall of the barrel body and used for accommodating filter residues, the feeding pipe is positioned at the outer side of the filter screen, and the discharging pipe is positioned at the inner side of the filter screen.
Further, a gland is connected above the barrel cover through bolts. The gland on the barrel body can prevent the position of the barrel cover from shifting.
Further, the barrel body is made of titanium steel materials. The service life is prolonged.
The beneficial effects of the utility model are as follows: a barrel body is arranged between the pressurizing kettle and the discharge valve, and a filter screen in the barrel body filters metal solid particles flowing through ore pulp; the feeding pipe is arranged above the discharging pipe, a certain height difference is formed, the flow rate of ore pulp can be weakened, the impact of the ore pulp is reduced, the barrel cover can be opened to clean sundries after the work is finished, and the abrasion of the ore pulp with metal solid particles to the discharging valve due to high-speed flushing is reduced more quickly and conveniently.

In the figure: 1-a barrel body; 2-a filter screen; 3-a barrel cover; 4-capping; 5-feeding pipe; 6, a discharging pipe; 7-pressurizing the kettle; 8-a bolt; 9-a discharge valve.
Detailed Description
The present utility model will be described in further detail with reference to the accompanying drawings and detailed description.
1-3, a device for prolonging service life of a discharge valve on a pressurized kettle comprises a barrel body 1, wherein a barrel cover 3 is arranged at the top of the barrel body 1, a filter screen 2 is arranged in the barrel body 1, a feed pipe 5 and a discharge pipe 6 are arranged on the barrel body 1, and the feed pipe 5 and the discharge pipe 6 are respectively positioned at two sides of the filter screen 2; the discharge end of the autoclave 7 is connected with the feed pipe 5, and the discharge valve 9 is arranged on the discharge pipe 6.
The feeding pipe 5 is positioned at the lower part of the barrel body 1, and the discharging pipe 6 is positioned at the upper part of the barrel body 1.
The filter screen 2 is the tube-shape setting, is equipped with certain space between filter screen 2 and the staving 1 inner wall, and inlet pipe 5 is located the filter screen 2 outside, and discharging pipe 6 is located the filter screen 2 inboard.
The upper part of the barrel cover 3 is connected with a gland 4 through a bolt 8.
The barrel body 1 is made of titanium steel.
Set up staving 1 between the pipeline between autoclave 7 and discharge valve 9, the discharge end of autoclave 7 links to each other with the inlet pipe 5 of staving 1, the discharging pipe 6 of staving 1 links to each other with the feed end of discharge valve 9, when the ore pulp of autoclave 7 outflow is through staving 1, filter screen 2 in staving 1 can filter the metal solid particle in the ore pulp, simultaneously because inlet pipe 5 is in discharging pipe 6 below, form certain difference in height can make the ore pulp velocity of flow weaken, thereby cause wearing and tearing when reducing ore pulp and directly flowing through discharge valve 9, can open bung 3 and clear up debris in the staving 1 after the work.
