Description

Technical Field

[0001] The utility model provides a water-cooled sleeve interface flange for a high-temperature purification equipment, belonging to the technical field of carbon-based material production equipment. Background Art

[0002] During the use of the high-temperature purification equipment, the temperature can reach above 2300°C. In order to effectively reduce the influence of high temperature on rubber products such as vacuum pipeline seals, a water-cooling structure needs to be added to the vacuum pipeline flange sleeve in contact with the furnace body to reduce the temperature. The traditional water-cooled sleeve interface flange is "mid-character-shaped". As Figure 1 shown, the flange sleeve penetrates through the water baffle, water channel and furnace wall from the outside and then enters the furnace body. The furnace body and the flange sleeve are fixedly connected by welding, and then a water baffle is welded. The space surrounded by the water baffle, furnace body and flange sleeve forms a water channel. When the high-temperature purification equipment operates, the water channel is filled with cooling water. The flange sleeve of this structure is an integral body, which can well ensure the installation accuracy of the flange. However, the welds bear the action of heat and cold for a long time, which may cause water to enter the furnace body from the welds. If water leaks inside the furnace body during the operation of the high-temperature purification equipment, it will seriously affect the safe production of the equipment and cause serious safety accidents.

[0032] As Figures 1 to 5 shown, the present utility model provides a water-cooled sleeve interface flange for a high-temperature purification equipment, including a furnace body 1, a first through hole 2 is provided on the furnace body 1, the first through hole penetrates through the inside and outside of the furnace body 1, a first limiting groove 3 is provided on the inner wall of the upper end of the first through hole 2, the first limiting groove 3 is close to the outside of the furnace body 1, the diameter of the first limiting groove 3 is larger than the diameter of the first through hole 2, a water channel groove 4 is provided between the first through hole 2 and the furnace body 1, a second limiting groove 12 is provided on the inner wall of the water channel groove, the second limiting groove 12 is lower than the upper end surface of the furnace body 1, and the second limiting groove 12 is higher than the first limiting groove 3.

[0033] A positioning mandrel 5 is placed on the first limiting groove 3. The positioning mandrel 5 includes a first positioning member 6. The bottom of the first positioning member 6 is in transitional fit with the first limiting groove 3. In this embodiment, the first positioning member 6 is cylindrical. One end of the first positioning member 6 is fixedly connected to a second positioning member 7. The second positioning member 7 is in transitional fit with the first through hole 2 at the lower end of the first limiting groove 3. In this embodiment, the second positioning member 7 is cylindrical, and the diameter of the second positioning member 7 is smaller than that of the first positioning member 6. The other end of the first positioning member 6 is fixedly connected to a handheld member 8. In this embodiment, the handheld member 8 is in a columnar structure or a handle structure, and the diameter of the handheld member 8 is smaller than that of the first through hole 2. Those skilled in the art can also make adaptive adjustments to the shape of the handheld member 8 as long as it is convenient for the operator to operate the positioning mandrel 5. The first positioning member 6 and the second positioning member 7 are coaxially arranged. In this embodiment, the first positioning member 6, the second positioning member 7 and the handheld member 8 are coaxially arranged. A positioning shoulder 9 is provided at one end of the first positioning member 6 close to the second positioning member 7, and a gap is left at the connection between the positioning shoulder 9 and the first limiting groove 3 to prevent the positioning mandrel 5 from wearing the first limiting groove 3. The positioning mandrel 5 is integrally provided.

[0034] A flange sleeve 10 is sleeved outside the positioning mandrel 5. The inner diameter of the flange sleeve 10 is the same as the diameter of the first limiting groove 3. The handheld member 8 of the positioning mandrel 5 can protrude from the upper end face of the flange sleeve 10. The flange sleeve 10 is in transitional fit with the positioning mandrel 5. Specifically, the lower end of the inner wall of the flange sleeve 10 is in transitional fit with the positioning mandrel 5. The first through hole 2, the positioning mandrel 5 and the flange sleeve 10 are coaxially arranged, and the lower end face of the flange sleeve 10 is welded to the peripheral of the upper end face of the furnace body 1. After the furnace body 1 and the flange sleeve 10 are welded, a "mountain" shape is formed.

[0035] Since the positioning mandrel 5 and the flange sleeve 10 are in transitional fit, and the positioning mandrel 5 and the first through hole 2 are in transitional fit, after the flange sleeve 10 is welded to the furnace body 1, the positioning mandrel 5 is removed.

[0036] The positioning mandrel 5 is of a solid structure or a hollow structure. In this embodiment, it is preferably of a solid structure.

[0037] If the positioning mandrel 5 is of a hollow structure, that is, a second through hole 11 is provided through the positioning mandrel 5, and the axis of the second through hole 11 is parallel to the axis of the first through hole 2. The wall thickness of the positioning mandrel 5 only needs to be able to support the flange sleeve 10 and the furnace body 1, and ensure the coaxiality of the through holes on the flange sleeve and the furnace body 1 when the flange sleeve 10 is welded to the furnace body 1, so as to ensure that the form and position tolerance between the furnace body 1 and the flange sleeve 10 is within the standard range. After the flange sleeve 10 is welded to the furnace body 1, the positioning mandrel 5 with a hollow structure can be removed. When the positioning mandrel 5 with a hollow structure is not removed, the inner diameter of the second through hole 11 is as large as possible under the condition of ensuring its support strength; ensure that the device connected to the end of the flange sleeve 10 away from the furnace body 1, the flange sleeve 10, and the positioning mandrel 5 with a hollow structure are adapted to each other.

[0038] A water retaining member 13 is welded on the second limiting groove 12. The upper end surface of the water retaining member 13 is flush with both ends of the furnace body 1. The upper end surface of the water retaining member 13 is higher than the welding joint between the flange sleeve 10 and the furnace body 1, and the lower end surface of the water retaining member 13 is lower than the welding joint between the flange sleeve 10 and the furnace body 1. The water retaining member 13, the furnace body 1, and the flange sleeve 10 form a closed space, which is the water channel groove 4. The water channel groove 4 is filled with cooling water, which can effectively reduce the temperature of the furnace body 1.

[0039] In the utility model, the flange sleeve 10 is welded to the upper end surface of the furnace body 1. The flange sleeve 10 is located outside the furnace body. The water retaining member 13 is welded to the upper end surface of the water channel groove 4 provided on the furnace body 1. Therefore, the welds are all on the outside of the furnace body 1, and the inside of the furnace body 1 is integrally arranged, effectively avoiding the situation that the cooling water in the water channel groove 4 seeps into the furnace, and ensuring the safe production of the high-temperature purification equipment. The positioning mandrel 5 of the utility model has an interference fit with the first limiting groove 3 and the inner wall of the flange sleeve 10, which can effectively ensure the coaxiality of the first through hole 2 on the flange sleeve 10 and the furnace body 1, and ensure that the form and position tolerance between the furnace body 1 and the flange sleeve 10 is within the standard range. After the flange sleeve 10 is welded to the furnace body 1, the positioning mandrel 5 is removed, and it can be reused, which has economy.
