Description

Technical Field

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

[0002] The autoclave is one of the key equipment in the pressure leaching process of nickel-cobalt sulfide by pressure oxygen wet method. The nickel-cobalt sulfide material is subjected to oxygen pressure leaching in the high-temperature and high-pressure environment of the autoclave. After leaching, the pulp is discharged to a flash tank through a discharge pipeline for pressure reduction and temperature reduction. Due to process control and maintenance needs, a connecting flange is provided on the discharge pipeline. 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 flange splash-proof covers 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. The non-metal splash-proof cover is easy to bundle and fix, but it is neither resistant to high temperature nor high pressure and has a short service life. Content of the Utility Model

[0004] Therefore, the utility model adopts the following technical solutions:

[0005] A splash-proof cover for a flange of a discharge pipeline of an autoclave includes a protective cylinder formed by curling a cover panel. Each end of the protective cylinder is provided with a circular side plate. The diameter of the circular side plate is adapted to the diameter of the protective cylinder. A central hole coaxially arranged with the circular side plate is provided in the middle of the circular side plate. A side plate opening communicating with the central hole is provided on the circular side plate. Each end of the protective cylinder is provided with a side baffle. A through hole coaxially arranged with the central hole is provided in the middle of the side baffle. The diameter of the through hole is the same as the diameter of the central hole. A fixing cylinder is provided at the through hole, and a pipe clamp is provided on the fixing cylinder.

[0006] Further, one end of the cover panel in the length direction is provided with a tongue in a triangular structure, and the tongue abuts against the end of the cover panel away from the tongue.

[0007] Further, the side baffle is composed of a plurality of side guards in a fan-shaped structure, and one side of the side guard is connected to the edge of the end of the protective cylinder.

[0008] Further, the fixing cylinder is composed of a plurality of wing plates corresponding to the side guards one by one, and one side of the wing plate is connected to the corresponding side guard.

[0009] The beneficial effects of the present utility model are as follows: The protective cylinder is formed by curling a stainless steel cover plate, which is sleeved on the flange, and circular side plates are arranged at both ends of the protective cylinder to support the protective cover.

[0013] The following will make a detailed description of the present utility model with reference to the drawings:

[0014] Such as Figure 1As shown in the figure, a splash-proof shield for the flange of the discharge pipeline of an autoclave includes a protective cylinder 2 formed by curling a cover plate 1. The cover plate 1 can be made of stainless steel plate. During use, the cover plate 1 can be curled on the flange to form the protective cylinder 2 for easy installation, so that it is not necessary to disassemble the flange from the pipeline during installation. In addition, for ease of use, one end of the cover plate 1 in the length direction is provided with a tongue 12 in a triangular structure. After the cover plate 1 is curled into the protective cylinder 2, the tongue 12 abuts against the end of the cover plate 1 away from the tongue, which can prevent the two ends of the cover plate 1 from being not easily aligned during installation. Each end of the protective cylinder 2 is provided with a circular side plate 3. The diameter of the circular side plate 3 is adapted to the diameter of the protective cylinder 2. The circular side plate 3 can support the protective cylinder 2 to prevent the protective cylinder 2 from deforming under external force, and at the same time prevent the protective cylinder 2 from directly contacting the flange. The middle of the circular side plate 3 is provided with a central hole 4 coaxially arranged with the circular side plate 3. The diameter of the central hole 4 is the same as the diameter of the pipelines at both ends of the flange. The pipelines at both ends of the flange can pass through the central hole 4. The circular side plate 3 is provided with a side plate opening 5 communicated with the central hole 4. The width of the side plate opening 5 is the same as the diameter of the pipelines at both ends of the flange. During installation, the pipeline can be inserted into the central hole 4 from the side plate opening 5. Each end of the protective cylinder 2 is provided with a side baffle 6. The middle of the side baffle 6 is provided with a through hole 7 coaxially arranged with the central hole 4, and the diameter of the through hole 7 is the same as the diameter of the central hole 4. The pipelines at both ends of the flange can pass through the through hole 7. Specifically, the side baffle 6 is composed of a plurality of side guards 8 in a fan-shaped structure. One side of the side guard 8 is connected to the edge of the end of the protective cylinder 2. A fixing cylinder 9 is provided at the through hole 7. The diameter of the fixing cylinder 9 is the same as that of the through hole 7. The two fixing cylinders 9 can be respectively sleeved on the pipelines at both ends of the flange for fixing the protective cylinder 2. Specifically, the fixing cylinder 9 is composed of a plurality of wing plates 10 corresponding one-to-one to the side guards 8. One side of the wing plate 10 is connected to the corresponding side guard 8. A pipe clamp 11 is provided on the fixing cylinder 9. The pipe clamp 11 can use the existing conventional pipe clamp. The pipe clamp 11 can bind the fixing cylinder 9, and then bind the protective cylinder 2 to the pipeline.

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

[0016] During installation, first install the two circular side plates 3 on the pipelines 13 at both ends of the flange respectively, then curl and wind the cover plate 1 on the flange to form the protective cylinder 2, and at the same time make the two circular side plates 3 located at both ends of the protective cylinder 2 to support the protective cylinder 2. Then abut the wing plate 10 against the pipeline to form the fixing cylinder 9. Finally, install the pipe clamp 11 on the fixing cylinder 9 to complete the installation (as Figure 2 shown). The whole process is fast and convenient. After installation, the protective cover is firmly fixed, not easily falling off during practical use, fully wrapping the flange, with good protection effect. At the same time, it is made of stainless steel, resistant to high temperature and high pressure, and has a long service life.
