DETAILED DESCRIPTION

[0016] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0017] As shown in Figure 1 and Figure 3 An efficient fluidization treatment device for oily sludge includes a multi-stage fluidization cavity for sequentially fluidizing the oily sludge, so that the fluidization process is more efficient. The present embodiment includes a primary fluidization cavity 8 and a secondary fluidization cavity 9.

[0018] As shown in Figure 2As shown, the fluidization cavity is horizontally long, and a rotating shaft 1 is installed inside the fluidization cavity, and a spiral blade is installed on the rotating shaft 1, and the rotating shaft 1 drives the spiral blade to rotate to play a role of transporting and stirring the oily sludge. An upstream of the fluidization cavity is provided with a feeding port 11 which is upwardly open, and a downstream is provided with a discharging port 10 which is downwardly open. The top of the fluidization cavity is provided with an opening which is communicated with the outside, and an upper cover 2, a partition plate 3 and a mesh plate 4 are installed in the opening from top to bottom in sequence, and the upper cover 2, the partition plate 3 and the mesh plate 4 are all provided with a space to form an intercavity, and the upper cover 2 is provided with a steam inlet 5 which is connected with a steam pipe 6, and the steam enters the intercavity between the upper cover 2 and the partition plate 3 through the steam inlet 5; the partition plate 3 is provided with a steam outlet 7 which is downwardly released, and the steam enters the intercavity between the partition plate 3 and the mesh plate 4 through the steam outlet 7; the mesh plate 4 is provided with mesh holes which are communicated with the space above and below the mesh plate 4, and the steam directly enters the fluidization cavity through the mesh plate 4 to mix with the oily sludge to realize high-efficiency fluidization.

[0019] Wherein, the upper cover 2, the partition plate 3 and the mesh plate 4 are all installed on the shell which wraps the fluidization cavity through the steps of the inner wall of the opening, and the mesh plate 4 is fixed with the step through bolts. When the fluidization cavity is filled with the oily sludge, the mesh plate 4 can play a role of filtering to block the larger sludge in the form of agglomerate to prevent the sludge from blocking the steam outlet 7 upwardly to ensure the smooth release of the steam. The sludge with high oil content or the sludge with smaller particle size will promote the combination with the steam even if it passes through the mesh plate 4 to improve the fluidization efficiency.

[0020] The sealing ring is arranged between the upper cover 2 and the shell, and the upper cover 2 is pressed tightly in use to prevent the steam from leaking. The heat insulation pad is arranged between the partition plate 3 and the shell, the partition plate 3 is made of heat-conducting material, and the resistance heater is installed on the partition plate 3 to heat the partition plate 3 to prevent the steam from being liquefied due to the temperature drop when entering the fluidization cavity.

[0021] Therefore, the oily sludge can be mixed with the steam in the fluidization cavity while being transported and stirred to realize high-efficiency fluidization in the transportation of the sludge to facilitate the subsequent oil sludge separation step.

[0022] In the embodiment, the secondary fluidization cavity 9 is one, and the primary fluidization cavity 8 is located above the secondary fluidization cavity 9, as shown in the figure. Figure 1As shown, the outlet 10 of the primary fluidization cavity 8 is connected with the inlet 11 of the secondary fluidization cavity 9. The direction of the helical blades in the secondary fluidization cavity 9 is opposite to that in the primary fluidization cavity 8. The sludge flows in a loop in the primary fluidization cavity 8 and the secondary fluidization cavity 9. Thus, the rotating shafts 1 in the primary fluidization cavity 8 and the secondary fluidization cavity 9 can be connected by belts, and a motor assembly 12 is connected on any one of the rotating shafts 1, reducing the number of power sources. A pulley 13 is installed on the end of each of the rotating shafts 1 of the primary fluidization cavity 8 and the secondary fluidization cavity 9, and the pulleys 13 are connected by a transmission belt 14. The rotation of any one of the rotating shafts 1 controlled by the motor assembly 12 can drive the other rotating shaft 1 to rotate synchronously.

[0023] The steam pipes 6 of the primary fluidization cavity 8 and the secondary fluidization cavity 9 are jointly connected to a steam main pipe 15, and a steam pump 16 is installed on each of the steam pipes 6. The steam pump 16 is used to fill the fluidization cavities with pressurized steam, ensure the flow direction of the steam, and promote the mixing of the steam and the sludge.

[0024] It is obvious for those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, and the present application can be implemented in other specific forms without departing from the spirit or essential characteristics of the present application. Therefore, the embodiments should be regarded as exemplary and non-limiting in any aspect.
