Description

Technical Field

[0001] The utility model belongs to the technical field of autoclave equipment, and relates to a splash-proof cover for a discharge valve of an autoclave. Background Art

[0002] The autoclave is one of the key equipment in the pressure oxygen leaching process for refining nickel-cobalt sulfide. The nickel-cobalt sulfide material undergoes oxygen pressure leaching in the high-temperature and high-pressure environment of the autoclave. After leaching, the pulp is discharged through the discharge valve to control the flow rate, and is discharged to the flash tank through the discharge pipeline for pressure reduction and temperature reduction. The discharge valve and the discharge pipeline are connected by a flange. Due to the pulse action generated by the discharge, thermal expansion and contraction, and aging of the gasket at the connecting flange, there is a phenomenon of leakage and splashing of high-temperature and high-pressure pulp, posing a great risk to safety production. The existing splash-proof covers for discharge valves are made of two materials, metal and non-metal. The metal splash-proof cover is resistant to high temperature and high pressure and has a long service life, but it is not firmly fixed and is easy to fall off. Although the non-metal splash-proof cover is easy to bundle and fix, it is neither resistant to high temperature nor high pressure and has a short service life. Content of the Utility Model

[0003] The purpose of the present utility model is to provide a splash-proof cover for a discharge valve of an autoclave in view of the problems existing in the prior art.

[0004] For this reason, the present utility model adopts the following technical solutions:

[0005] A splash-proof cover for a discharge valve of an autoclave, including a box body, the bottom of the box body is hinged with a movable door, each of the side walls at both ends in the length direction of the box body is provided with a corresponding pipeline slot, the top of the pipeline slot is of an arc structure, the movable door is provided with a wing plate corresponding to the pipeline slot, the wing plate abuts against the inner wall of the box body, the top of the wing plate is provided with a wing plate opening of an arc structure, and the top end of the box body is provided with a valve shaft hole.

[0006] Further, a buckle is provided at the edge of the movable door.

[0007] The beneficial effect of the present utility model lies in that: pipeline slots and corresponding wing plates are arranged on the box body, and the pipelines at both ends of the discharge valve are clamped through the wing plate openings and the pipeline slots on the wing plates, so that the box body is firmly installed on the discharge valve and is not easy to fall off during use, and can effectively prevent the discharge valve from splashing; the installation method is simple and convenient.

[0012] The following will make a detailed description of the present utility model in conjunction with the accompanying drawings:

[0013] As Figures 1-3 shown, a splash-proof cover for the discharge valve of an autoclave includes a box body 1. The size of the box body 1 is adapted to the discharge valve, and the discharge valve can be installed into the box body 1. A movable door 2 is hinged at the bottom of the box body 1. During installation, the movable door 2 can be opened, and the discharge valve can be placed into the box body 1 from the bottom of the box body 1. Each of the side walls at both ends in the length direction of the box body 1 is provided with a corresponding pipe slot 3. The top of the pipe slot 3 is of an arc structure and the radius is adapted to the radius of the pipes at both ends of the discharge valve. During installation, the pipes at both ends of the discharge valve can be clamped into the pipe slot 3, and the pipes are made to abut against the top of the pipe slot 3. A side wing plate 4 corresponding to the pipe slot 3 is provided at the position where the movable door 2 is close to the pipe slot 3. The side wing plate 4 abuts against the inner wall of the box body 1. The top of the side wing plate 4 is provided with an arc-shaped wing plate opening 5, and the radius of the wing plate opening 5 is also adapted to the radius of the pipes at both ends of the discharge valve. After the pipes at both ends of the discharge valve are clamped into the pipe slot, the movable door 2 is closed. The side wing plate 4 can block the lower part of the pipe slot 3, and at the same time, the lower parts of the pipes at both ends of the discharge valve are placed into the wing plate opening 5. The pipes at both ends of the discharge valve are clamped by the wing plate opening 5 and the pipe slot 3, so that the box body 1 is stably installed on the discharge valve. A valve shaft hole 6 is provided at the top of the box body 1, and the valve shaft of the discharge valve can pass through the valve shaft hole 6.

[0014] A buckle 7 is provided at the edge of the movable door 2. The buckle 7 can adopt the existing conventional buckle 7. After the movable door 2 is closed, it can be fixed by the buckle 7.

[0015] The usage method of the present utility model is as follows:

[0016] The box body 1 is buckled onto the discharge valve from top to bottom, so that the pipes at both ends of the discharge valve are located in the pipe slot 3 and abut against the top of the pipe slot 3. At the same time, the valve shaft of the discharge valve passes through the valve shaft hole 6. Then the movable door 2 is closed, and the buckle 7 is fixed. After the movable door 2 is closed, the side wing plate 4 can block the lower part of the pipe slot 3, and at the same time, the pipes at both ends of the discharge valve are clamped into the wing plate opening 5 of the side wing plate 4, thereby clamping the pipes at both ends of the discharge valve. The installation operation is completed. The installation process is simple and convenient, and the fixation is firm. It is not easy to fall off during use, and can effectively prevent the discharge valve from splashing.
