Description

Technical Field

[0001] The utility model relates to the field of oil sludge conveying equipment, in particular to an oil temperature resistant shell sealing structure. Background Art

[0002] Oil sludge thermal remediation technology is an advanced technology for treating oil sludge pollution, and is usually applicable to oil sludge scenarios that require on-site treatment or recycling of contaminated sludge.

[0003] At present, the oil sludge thermal remediation technology will put the contaminated oil sludge into the kiln for high-temperature pyrolysis and carbonization, and then transport it to the yard through the discharging scraper. During the transportation process, a large barrel shell is usually used for transportation. Due to the complex composition of the oil sludge, the temperature of the oil sludge after pyrolysis is about 400°C, and it also contains a large amount of oil-water mixed gas. During the transportation process, it will penetrate the sealing gasket and condense, causing a large amount of black oil stains to drip from the flange joints. At a temperature of 400°C, the oil-containing gas will seriously corrode the sealing gasket, causing the sealing gasket to fail quickly, and a large amount of oil-containing gas will emerge from the shell, and black oil stains will drip, affecting the appearance of the equipment and polluting the surrounding environment.

[0004] In addition, during the transportation process, the edge of the shell is easily deformed after being hit, and the deformed position is more likely to cause oil leakage problems. Utility Model Content

DETAILED DESCRIPTION

[0021] In order to make it easier to understand the structure of the present invention and the functional features and advantages that can be achieved, the preferred embodiments of the present invention are described in detail with reference to the drawings as follows:

[0022] Example:

[0023] like Figures 1 to 6 As shown, the utility model provides an oil-temperature resistant shell sealing structure, including a shell 1 and a cover plate 2. The shell 1 is opened on one side, and the shell 1 is closed on the open side by a bottom plate 11. The shell 1 and the cover plate 2 are usually barrel-shaped, and are made of steel, such as carbon steel, or composite materials, such as glass fiber reinforced materials, with stable chemical properties and high temperature resistance, and are coated with a heat-resistant coating inside. A boss 3 is fixedly connected to the middle of the cover plate 2, and the boss 3 and the cover plate 2 are integrally formed. The boss 3 is embedded in the shell 1, and the boss 3 and the shell 1 are interference fit. A sealing gasket 41 is movably connected between the edge of the shell 1 and the edge of the cover plate 2, and the shell 1 is movably connected to the cover plate 2. A protective mechanism 5 is movably connected to the edge of the shell 1 and the edge of the cover plate 2.

[0024] The shell 1 has a first extension plate 12 extending from a side edge close to the cover plate 2, and the cover plate 2 has a second extension plate 21 extending from an edge of the boss 3. The first extension plate 12 and the second extension plate 21 are movably connected via a threaded flange 42. A baffle 212 is fixedly connected to the edge of the second extension plate 21, and the baffle 212 contacts the first extension plate 12. The baffle 212 extends downward, and the diameter of the baffle 212 is greater than the diameter of the first extension plate 12. The baffle 212 facilitates buckling the cover plate 2 and the second extension plate 21 on the shell 1 and the first extension plate 12. After the cover plate 2 is buckled on the shell 1, the cover plate 2 and the shell 1 are fixed by the threaded flange 42. The first extension plate 12 is integrally formed with the shell 1, and the second extension plate 21 is integrally formed with the cover plate 2.

[0025] As another example, Figure 2 and Figure 3 As shown, the first extension plate 12 of the present application is protrudingly provided with a first convex groove 121, and the second extension plate 21 is protrudingly provided with a second convex groove 211. The openings of the first convex groove 121 and the second convex groove 211 correspond to each other, and the sealing gasket 41 is embedded in the first convex groove 121 and the second convex groove 211. When in use, after the sealing gasket 41 is embedded in the first convex groove 121 or the second convex groove 211, the threaded flange 42 is tightened. After the first convex groove 121 and the second convex groove 211 are provided, after the sealing gasket 41 fails, the distance between the first extension plate 12 and the second extension plate 21 is small due to the absence of the sealing gasket 41, and the threaded flange 42 can still effectively press the first extension plate 12 and the second extension plate 21. If there is no first convex groove 121 and second convex groove 211, the sealing gasket 41 needs to be placed directly between the first extension plate 12 and the second extension plate 21. When the threaded flange 42 presses the two together, there is a certain gap due to the obstruction of the sealing gasket 41 in the middle, and the gap still exists after the sealing gasket 41 is melted or damaged by high temperature. Therefore, the first convex groove 121 and the second convex groove 211 are provided, and the provision of the two facilitates the replacement of the sealing gasket 41.

[0026] As another example, Figures 4 to 6As shown, the protective mechanism 5 of the present application includes two protective frames 51, both of which are plugged into the outside of the first extension plate 12 and the second extension plate 21, and the two protective frames 51 are arranged correspondingly. The protective mechanism 5 also includes bolts 52 and threaded holes 53. A plurality of threaded holes 53 are evenly spaced and arranged on the side of the protective frame 51 close to the second extension plate 21. The bolts 52 are inserted into the threaded holes 53, and the bolts 52 are movably abutted against the second extension plate 21. When in use, the two protective frames 51 are inserted from the sides of the first extension plate 12 and the second extension plate 21. The gap between each protective frame 51 is slightly larger than the height of the first convex groove 121 plus the second convex groove 211. Each protective frame 51 is semicircular or other shapes that are the same as the shape of the cover plate 2 after splicing. Then, the bolts 52 are threadedly connected in the threaded holes 53, and the side of the bolts 52 close to the second extension plate 21 abuts against the second extension plate 21, so that the protective frame 51 can be fixed.

[0027] A telescopic rod 54 is fixedly connected to one side of the protective frame 51 near the first extension plate 12, and a curved plate 55 is fixedly connected to the other end of the telescopic rod 54. A spring 57 is provided on the outer sleeve of the telescopic rod 54, and the curved plate 55 is in active contact with the threaded flange 42. An oil-absorbing pad 56 is fixedly connected to one side of the curved plate 55 near the threaded flange 42. The curved plate 55 is squeezed by the baffle 212 during the process of the protective frame 51 being sleeved on the outside of the first extension plate 12 and the second extension plate 21, and is reset when it is located below the threaded flange 42. The oil-absorbing pad 56 on the curved plate 55 is in contact with the threaded flange 42, and the oil sludge flowing out of the gap of the threaded flange 42 is received by the oil-absorbing pad 56. The oil-absorbing pad 56 can be a sponge or an oil-absorbing cloth.

[0028] The working principle of the oil temperature resistant housing sealing structure of the present application is as follows: when in use, a sealing gasket 41 is embedded in the first convex groove 121, the cover plate 2 is covered to the opening side of the housing 1, the boss 3 is interference fit with the opening side of the housing 1, the first convex groove 121 corresponds to the second convex groove 211, and the first extension plate 12 and the second extension plate 21 are fixedly connected through the threaded flange 42. The two protective frames 51 are inserted from the side of the first extension plate 12 and the second extension plate 21, and the bolts 52 are threadedly connected in the threaded holes 53. The side of the bolt 52 close to the second extension plate 21 abuts against the second extension plate 21, and the protective frame 51 can be fixed. The arc plate 55 is squeezed by the baffle 212 during the process of the protective frame 51 being sleeved on the outside of the first extension plate 12 and the second extension plate 21, and resets when it is located below the threaded flange 42. The oil absorption pad 56 on the arc plate 55 contacts the threaded flange 42, and the oil sludge flowing out of the gap of the threaded flange 42 is received and absorbed by the oil absorption pad 56.
