Description

Technical Field

[0001] The invention relates to the field of oil sludge treatment equipment, and more specifically to an oil-water-slag three-phase separator suitable for oil sludge treatment. Background Art

[0002] Oily sludge is one of the dangerous substances in the process of oil development, refining, processing, transportation and production. The output of the oil industry is large. If it is not handled properly, it will cause pollution to the surrounding environment. At present, most companies still mainly use incineration and landfill as the treatment methods. A few companies use oil-water-slag three-phase separators to treat oily sludge. The oil-water-slag three-phase separator uses centrifugal force to separate the mixture containing oil, water and solid particles. It is mainly composed of a casing, a differential drive, a drum, a rotary pusher, a slag discharge pipe, a liquid discharge pipe, a feeding mechanism, a powder device, two drive motors, etc. When in use, the drum and the rotary pusher rotate in the same direction at high speed under the drive of the drive motor, and the mixture rotates at high speed under the drive of the drum and the rotary pusher. The particles in the mixture are deposited on the inner wall of the drum under the action of centrifugal force. Due to the differential speed between the drum and the rotary pusher, the rotary pusher pushes the particles on the inner wall of the drum and is discharged from the slag discharge port.

[0003] However, the particulate matter discharged from the oil-water-slag three-phase separator contains a lot of water and cannot meet the requirements for solid-liquid separation. The particulate matter needs to be treated secondary, which is time-consuming and labor-intensive and has low treatment efficiency. Therefore, it is urgent to design an oil-water-slag three-phase separator suitable for sludge treatment. Summary of the invention

[0039] Working principle:

[0040] First, the three-phase separation device 1 operates normally, and then the flat drum 106, the reduction drum 107, and the screw pusher 109 rotate at high speed. Then, due to the speed difference between the flat drum 106, the reduction drum 107 and the screw pusher 109, the screw pusher 109 pushes the particles on the inner walls of the flat drum 106 and the reduction drum 107 to be discharged from the slag discharge channel 108, which has an extrusion effect to achieve one-time dehydration. Then, the particles fly to the inner wall of the microporous filter tube 207 under the action of centrifugal force, and then the flat drum 106 rotates with the centrifugal tube 201 at high speed, and the centrifugal tube 201 rotates with the microporous filter tube 207 at high speed. Then, the particles adhere to the inner wall of the microporous filter tube 207 under the action of centrifugal force, and then the water in the particles is removed by the centrifugal force. The water passes through the small holes on the microporous filter tube 207 and the dehydration grid space 204 to the inner wall of the shielding outer tube 206, and then flows downward along the inner wall of the shielding outer tube 206 under the action of gravity, and then the water falls from the right end of the shielding outer tube 206, and then the water gathers on the bottom surface of the inner cavity of the isolation casing 105, and then the water is discharged from the drain pipe, realizing the effect of centrifugal dehydration, and achieving the effect of secondary dehydration. In this process, the plug-in effect between the T-shaped guide rail 43 and the T-shaped track groove 42 restricts the reciprocating transfer plate 41, so that the reciprocating transfer plate 41 cannot rotate, and then the straight drum 106 rotates with the reciprocating threaded tube 46, and then the threaded mating component 45 reciprocates left and right under the action of the threaded mating between it and the reciprocating threaded tube 46, and then the threaded mating component 45 The reciprocating transfer plate 41 moves back and forth left and right, and then the reciprocating transfer plate 41 moves back and forth left and right with the reciprocating push tube 47. When the reciprocating transfer plate 41 and the reciprocating push tube 47 move to the left, the contact roller 34 rolls on the left end face of the reciprocating push tube 47, and the left end face of the reciprocating push tube 47 applies a left thrust to the contact roller 34. Then the contact roller 34 slides to the left inside the displacement slit space 32 with the L-shaped linkage 33, and then the displacement slit space 32 slides to the left with the front arc push plate 311, and then the front arc push plate 311 pushes the particles in the corresponding area on the inner wall of the microporous filter tube 207 to slide to the left. At the same time, the reciprocating transfer plate 41 moves to the left to pull the pull-back wire rope 72, and then the pull-back wire rope 72 takes the fixed pull-back wheel 73 as the base point. A rightward pulling force is applied to the strong extrusion plate 62, and then the strong extrusion plate 62 moves to the right, and then the strong extrusion plate 62 pulls the strong spring 61, the strong spring 61 elastically stretches, and the elastic potential energy increases, and then the rear arc push plate 312 moves to the right under the elastic pulling force of the corresponding return spring 35, and then the rear arc push plate 312 moves synchronously with the staggered pulley 53 through the staggered slide rod 52, so that the staggered pulley 53 is always in contact with the surface of the strong extrusion plate 62, and then the slag discharge channel 108 corresponding to the front arc push plate 311 is gradually blocked by the front arc push plate 311, and the slag discharge channel 108 corresponding to the rear arc push plate 312 is gradually opened, and the left cavity of the rear arc push plate 312 is emptied to accommodate the newly discharged particles from the slag discharge channel 108.When the reciprocating transfer plate 41 and the reciprocating push tube 47 move to the right, the front arc push plate 311 moves to the right under the elastic tension of the corresponding reset spring 35, the corresponding slag discharge channel 108 is gradually opened, the corresponding cavity is emptied, and the strong extrusion plate 62 moves to the left under the elastic tension of the strong spring 61, and the strong extrusion plate 62 moves with the pull-back wire rope 72 to make the pull-back wire rope 72 always tight, and then the strong extrusion plate 62 moves to the left with the staggered slide rod 52 through the staggered pulley 53, and then the staggered slide rod 52 moves the rear arc push plate 312 to the left, and then the rear arc push plate 312 applies a leftward squeezing force to the particles in the corresponding area on the inner wall of the microporous filter tube 207, which has a dehydration effect, and at the same time pushes the particles to move to the left to empty the cavity aligned with the corresponding slag discharge channel 108, and then repeats the above work to achieve the third dehydration, and then the dehydrated particles gradually move to the left, and then the particles are discharged from the left end of the microporous filter tube 207 into the slag discharge flat box 102, and then the particles are discharged from the bottom of the slag discharge flat box 102.
