DETAILED DESCRIPTION

[0028] The utility model will be further described below in combination with the drawings and specific embodiments.

[0029] As Figures 1-6 shown:

[0030] A continuous rotary thermal phase separation device includes a casing 1, a frame 2, a feed pipe 3, a solid discharge pipe 4, and a gas discharge pipe 11. The gas discharge pipe 11 is inserted into the top of the casing 1 and connects to the interior of the casing 1. Oil and gas can be discharged through the gas discharge pipe 11. The top of the casing 1 is connected to the frame 2 by screws. The bottom of the side wall of the casing 1 is connected to the feed pipe 3 by a flange and connects to the interior of the casing 1. The solid discharge pipe 4 is provided at the bottom of the casing 1 and connects to the interior of the casing 1 through a central discharge pipe 14. The solid discharge pipe 4 and the central discharge pipe 14 are perpendicular and the two pipes are internally connected. An outer spiral blade 15 and an inner spiral blade 16 are provided inside the casing 1.

[0031] The casing 1 is internally equipped with an outer chamber wall 12, an inner chamber wall 13, and a central discharge pipe 14. The bottom of the outer chamber wall 12 is welded to the bottom of the casing 1, and the top of the outer chamber wall 12 is welded to the top of the inner wall of the casing 1. An opening is provided at the top of the outer chamber wall 12, and the openings are evenly distributed around the center of the casing 1. The opening at the top of the outer chamber wall 12 can transport the material conveyed by the outer spiral blade 15 to the mixing and transport section of the inner chamber wall. The top of the inner chamber wall 13 is welded to the top of the casing 1. The central discharge pipe 14 is inserted into the center of the bottom of the casing 1 and is connected to the solid discharge pipe 4 through a flange. The outer chamber wall 12 and the inner chamber wall 13 cooperate to form an S-shaped transport line. The S-shaped transport line can facilitate the thermal phase separation and mixing of oily sludge, which not only increases the transport length but also increases the transport and mixing function. It can also use the up-and-down movement of the S-shape to drop and disperse the oily sludge, greatly improving the reaction efficiency and working effect of the material.

[0032] An outer spiral blade 15 is disposed between the outer chamber wall 12 and the inner wall of the housing 1. The outer spiral blade 15 can transport the feed material upward through the spiral blade, and then convey it through the opening of the outer chamber wall 12 to the space between the outer chamber wall 12 and the inner chamber wall 13. The material collection plate 21 at the gap between the outer chamber wall 12 and the inner chamber wall 13 concentrates the material between the inner chamber wall 13 and the central discharge pipe 14. An inner spiral blade 16 is disposed between the inner chamber wall 13 and the central discharge pipe 14. The inner spiral blade 16 can use the spiral blade to continue to transport the material upward, and then the material will fall into the central discharge pipe 14. The feeding direction of the outer spiral blade 15 is upward.

[0033] A material collecting plate 21 is installed at the bottom of the inner wall 13. The material collecting plate 21 is funnel-shaped, which can better transport materials to the location of the inner spiral blade 16. The outer spiral blade 15 forms a spiral funnel shape towards the central discharge pipe 14, and the inner spiral blade 16 forms a spiral funnel shape towards the central discharge pipe 14. The spiral shape and the angle towards the center can concentrate the transported materials at the center, and then smoothly enter the next stage of rotation, so that the materials can be transported smoothly without stopping or accumulating inside the machine.

[0034] An outer turntable 7 and an inner turntable 8 are arranged on the upper part of the housing 1. A sliding ring 22 is arranged below the outer turntable 7 and the inner turntable 8. The outer turntable 7 and the inner turntable 8 are slidably connected to the sliding ring 22. The sliding ring 22 is connected to the housing 1 by screws. The sliding connection can ensure smooth movement and sealing, and also facilitate the disassembly of the outer turntable 7 and the inner turntable 8, thereby facilitating internal maintenance and cleaning.

[0035] The outer spiral blade 15 and the outer turntable 7 are fixedly connected by the outer connecting column 17, and the inner spiral blade 16 and the inner turntable 8 are fixedly connected by the inner connecting column 18. The outer turntable 7 drives the outer spiral blade 15 to rotate, and the inner turntable 8 drives the inner spiral blade 16 to rotate. During the rotation, the outer spiral blade 15 and the inner spiral blade 16 agitate the oily sludge inside and simultaneously transport the sludge upwards.

[0036] A rotary gear 6 is provided on the upper surface of the outer turntable 7. The rotary gear 6 is evenly distributed around the center of the outer turntable 7. A rotary motor 5 is provided on the frame 2. The output end of the rotary motor 5 is keyed to a power gear, which meshes with the rotary gear 6. The motor drives the power gear, which meshes with the rotary gear 6. Since the rotary gear 6 is connected to the outer turntable 7 by screws, the rotary gear 6 can be used to drive the outer turntable 7 to rotate.

[0037] The inner turntable 8 and the outer turntable 7 are fixedly connected by a latch 9. The outer turntable 7 and the inner turntable 8 are connected as a whole, so that the outer turntable 7 and the inner turntable 8 can rotate simultaneously, thereby driving the outer spiral blade 15 and the inner spiral blade 16 below to rotate at once.

[0038] The gas discharge pipe 11 is connected to the top of the casing 1 in an inverted funnel shape. A fan 10 is installed on the gas discharge pipe 11. A feed spiral blade 19 is installed inside the feed pipe 3, and a discharge spiral blade 20 is installed inside the solid discharge pipe 4. Since the oily sludge is not liquid, the spiral blades transport the material and also serve as a material feeder. After thermal phase separation, solid impurities are discharged; therefore, the spiral blades of the discharge spiral blade 20 are used to feed and discharge the solid material.

[0039] How this example works:

[0040] During operation, the oily sludge requiring thermal phase separation is conveyed and fed into the thermal phase separation equipment through the feed pipe 3 and the feed spiral blade 19. The casing 1, outer chamber wall 12, and inner chamber wall 13 of the thermal phase separation equipment are hollow structures. The interior is heated by high-temperature flue gas, and the heat is used to perform thermal phase separation on the oily sludge inside. After being fed through the feed pipe 3, the sludge is conveyed upward through the outer spiral blade 15. The outer spiral blade 15 is inclined towards the center, and the spiral structure helps to guide the material towards the center during the thermal phase separation process. The material is transported upwards and can also be concentrated towards the center. When the material is transported to the highest point, it will enter the gap between the outer wall 12 and the inner wall 13 through the opening above the outer wall 12. It will fall from a height in the gap and fall onto the collection plate 21. With the help of gravity, the material can be broken up, which can prevent the material from clumping. At the same time, the spiral structure is used to stir the material, so that the material can be continuously stirred and turned over, so that the oily sludge can react evenly inside and out, improving work efficiency and reaction degree, thereby ensuring a more complete thermal phase separation reaction.

[0041] The sludge-containing material is conveyed through the gap between the outer wall 12 and the inner wall 13 of the collection plate 21 to the inner spiral blade 16 via the inclined mechanism of the collection plate 21. The inner spiral blade 16, like the outer spiral blade 15, uses a spiral structure inclined towards the center to transport the sludge from bottom to top and concentrate it towards the center. The two spiral structures mix, transport, and perform thermal phase separation of the material, which can effectively improve the thermal phase separation effect and avoid the problem of sludge clumping and clogging of the pipes after thermal phase separation. This effectively improves the quality of work, ensures smooth operation, and makes the work more ideal.
