Description

Technical Field

[0001] This invention relates to the field of high-efficiency separation technology, and in particular to a high-efficiency separation device for reducing the volume of oily sludge. Background Technology

[0002] Oily sludge is a typical hazardous solid waste generated during crude oil extraction, gathering, transportation, storage, refining, chemical processing, and oily wastewater treatment. Its composition is complex, mainly consisting of a mixture of oil, water, and silt. The oil phase readily adsorbs onto the surface of solid particles, and the oil and water easily form a stable emulsion system, making separation extremely difficult. With increasingly stringent environmental regulations, the harmless disposal and resource recovery of oily sludge have become a core necessity for the green development of the petroleum and petrochemical industry. This requires not only significant sludge reduction but also ensuring efficient oil phase recovery, compliant water phase discharge, and sludge cake that meets subsequent landfill or resource utilization standards.

[0003] Currently, the reduction and separation of oily sludge mostly employs mechanical separation processes. Among these, horizontal screw centrifuges and plate and frame filter presses are the most widely used core equipment in the industry, becoming the mainstream choice for solid-liquid separation of oily sludge due to their ease of operation and high processing efficiency. However, in practical engineering applications, relying solely on centrifuges or filter presses for separation has insurmountable technical drawbacks, severely restricting the treatment effect and resource utilization rate of oily sludge.

[0004] The specific problems are as follows: The oil content of the mud cake is too high, which cannot meet the standards for subsequent treatment. A single centrifuge relies solely on centrifugal force to achieve coarse separation of oil, water, and mud, and its ability to desorb heavy oil and aged oil adsorbed in the micropores of mud and sand is insufficient. Summary of the Invention

[0005] The purpose of this invention is to address the problem that a single centrifuge, relying solely on centrifugal force to achieve coarse separation of oil, water, and sludge, has insufficient desorption capacity for heavy oil and aged oil adsorbed in the micropores of mud and sand. Therefore, this invention proposes a high-efficiency separation device for reducing the volume of sludge and oil.

[0006] To achieve the above objectives, the present invention employs the following technology: a high-efficiency separation device for reducing oily sludge volume; comprising a base frame and a support frame and a placement frame mounted on the base frame, and further comprising: a separation component disposed on the base frame;

[0007] The separation assembly includes a mixing tank connected to the side of the support frame. The top of the mixing tank is connected to a discharge port. A motor is installed on the top of the placement frame, and the output end of the motor is connected to a rotating shaft extending into the mixing tank. The rotating shaft is connected to a rotating shaft through an adjustment assembly.

A liquid discharge port is opened on the outer periphery of the mixing tank. A collection box is connected to the outer wall of the mixing tank.

Positioning rods are fixed to the two eccentric plates away from the center and close to the edge. A fixing cylinder is fixed to the inner wall of the mixing tank.

[0009] Further description of a high-efficiency separation device for reducing and treating oily sludge using the above-mentioned technology: The outer wall of the fixed cylinder has a feed inlet that communicates with the inner wall of the mixing tank, the bottom of the fixed cylinder has several liquid outlets, and the inner wall of the fixed cylinder is slidably connected to an extrusion block.

[0010] Further description of a high-efficiency separation device for reducing and treating oily sludge using the above-mentioned technology: Two mounting brackets are fixed to the top of the extrusion block, and a connecting rod is fixed between the two mounting brackets. A second sleeve rod is rotatably connected to the outer circumference of the connecting rod, and a first sleeve rod is rotatably connected to the outer circumference of the positioning rod. The first sleeve rod and the second sleeve rod are slidably connected by an adjusting component.

[0011] Further description of a high-efficiency separation device for reducing and treating oily sludge using the above-mentioned technology: The second sleeve rod is slidably connected inside the first sleeve rod. The adjusting component includes a through groove that is opened through one side of the first sleeve rod, an extension plate that contacts the through groove is fixed on one side of the second sleeve rod, a welding plate is fixed on one side of the first sleeve rod, and an electric push rod is installed between the welding plate and the extension plate.

[0012] Further description of a high-efficiency separation device for reducing and treating oily sludge using the above-mentioned technology: The outer periphery of the fixed cylinder is provided with a groove, and the inner wall of the groove is slidably connected with a sealing plate. The surface of the sealing plate is also provided with several liquid outlets.

[0013] Further description of a high-efficiency separation device for reducing and treating oily sludge using the above-mentioned technology: An actuating assembly is provided between the rotating shaft and the collection box. The actuating assembly includes a reciprocating screw rotatably connected inside the collection box. The reciprocating screw and the rotating shaft are provided with gear grooves on their outer periphery. The reciprocating screw and the rotating shaft are connected by a pulley. A fixing rod is fixed to the inner wall of the collection box. A slider is slidably connected to the outer periphery of the fixing rod. A rotating rod is rotatably connected to the top of the slider. An embedded block is fixed to the top of the rotating rod and embedded in the reciprocating screw.

[0014] Further description of a high-efficiency separation device for reducing and treating oily sludge using the above-mentioned technology: The bottom of the slider is fixed with a connecting frame, and a central rod is fixed between the inner walls of the connecting frame. A toggle plate is rotatably connected to the outer circumference of the central rod. An opening is provided on one side of the collection box, and an oil collection tank is installed on one side of the collection box.

[0015] In summary, due to the adoption of the above-mentioned technology in this efficient separation device for reducing oily sludge volume, the beneficial effects of this invention are: With the separation, adjustment, and actuation components in place, when processing oily sludge, the material to be processed is fed into the mixing tank through the feed port at the top of the tank. The motor is then started, and its output drives the rotating shaft to rotate synchronously. The rotating blades on the outer periphery of the rotating shaft rotate at high speed against the inner wall of the mixing tank, fully mixing and shearing the oily sludge. This effectively breaks the adsorption and adhesion between the mud and sand particles and the oil phase, completely breaking the stable oil-water emulsion system. The oil and water separated by the mixing flow into the collection tank through the discharge port, quickly completing the initial oil-water separation. At the same time, the rotating blades can scrape off the sludge adhering to the tank wall and push it forward, preventing material agglomeration and wall adhesion problems, and ensuring continuous and stable operation. While the rotating shaft rotates, the adjusting component drives the rotating shaft to rotate synchronously, and the eccentric plate performs eccentric rotational motion. Through the linkage transmission of the positioning rod, the first sleeve rod, and the second sleeve rod, the extrusion block is driven to perform reciprocating linear extrusion on the inner wall of the fixed cylinder. The stirred oily sludge is pushed to the feed port by the rotating blades and then enters the inside of the fixed cylinder. The extrusion block continuously applies pressure to the sludge, deeply squeezing out the remaining free and emulsified oil and water in the sludge. The oil and water seeps into the collection box through the liquid outlet, while the sludge is intercepted and solidified, realizing the secondary separation of oil and water and sludge, greatly reducing the oil content of the sludge and improving the sludge reduction effect. For oily sludge with different viscosities and oil content, the electric push rod can be activated to extend and retract, driving the extension plate to slide in the through groove. By changing the extension length of the second set of rods, the extrusion stroke and extrusion force of the extrusion block can be flexibly adjusted, greatly improving the adaptability of the device to various types of oily sludge and ensuring that different materials can be separated efficiently. The sludge after secondary extrusion is pressed into a sludge cake. By pulling the sealing plate along the groove, the sealing plate can be quickly pulled out and the sludge cake can be removed, simplifying the sludge collection process and improving the disposal efficiency. When the rotating shaft continues to rotate, the pulley drives the reciprocating screw to rotate synchronously. The embedded block, in conjunction with the screw thread groove, drives the slider to slide horizontally back and forth along the fixed rod, thereby driving the connecting frame and the agitator plate to move synchronously. This continuously agitates the oil-water mixture in the collection tank. Utilizing the density difference between oil and water, tiny oil droplets collide and coalesce quickly, rising to form an oil layer, while the water phase settles and separates, avoiding secondary emulsification. When the agitator plate moves to the left, it adheres closely to the connecting frame, pushing the oil layer to undulate and guide its flow. The coalesced oil flows into the oil collection tank through the opening for recycling, ensuring the purity of the recycled oil. The water phase is discharged through the outlet, achieving fine separation of oil and water. Attached Figure Description

[0018] The following will describe in detail, with reference to the accompanying drawings of the embodiments of the present invention, a high-efficiency separation device for reducing oily sludge volume. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] like Figures 1-8As shown, the present invention provides a high-efficiency separation device for reducing the volume of oily sludge: including a base frame 11 and a support frame 12 and a placement frame 13 installed on the base frame 11, and further including a separation component 20 disposed on the base frame 11; like Figure 1 , Figure 2 , Figure 3 As shown, the separation component 20 includes a mixing tank 21 connected to the side of the support frame 12. The top of the mixing tank 21 is connected to a discharge port 211. A motor 22 is installed on the top of the placement frame 13, and the output end of the motor 22 is connected to a rotating shaft 23 extending into the mixing tank 21. The rotating shaft 23 is connected to a rotating shaft 231 through an adjustment component 30. Rotating blades 24 that fit against the inner wall of the mixing tank 21 are connected to the outer periphery of the rotating shaft 23. A liquid outlet 25 is opened on the outer periphery of the mixing tank 21. A collection box 26 is connected to the outer wall of the mixing tank 21. A water outlet 261 is connected to one side of the collection box 26. A baffle plate 27 is fixed to the inner wall of the mixing tank 21. When oily sludge needs to be treated, the sludge to be treated is put into the mixing tank 21 through the feed port 211 at the top of the mixing tank 21. Then the motor 22 is started, and the output end of the motor 22 drives the rotating shaft 23 to rotate synchronously. The rotating blades 24 on the outer periphery of the rotating shaft 23 rotate at high speed against the inner wall of the mixing tank 21, which fully mixes, shears and breaks the sludge. On the one hand, it breaks the adsorption and adhesion state between the mud and sand particles and the oil phase, and breaks the stable oil-water emulsion system. As the mixing is carried out, the oil and water will also enter the collection tank 26 through the liquid outlet 25, and the oil-water separation of the sludge is initially completed. On the other hand, the mud stirred by the rotating blades 24 adheres to the inner wall of the mixing tank 21. As the rotating blades 24 continue to rotate, the rotating blades 24 push the mud on the inner wall of the mixing tank 21 to fall off and move forward, avoiding local agglomeration and sticking to the wall. During the mixing process, the baffle 27 can block the splashing of materials and prevent untreated materials from directly entering the collection area.

[0020] like Figure 1 , Figure 3 , Figure 4 , Figure 5As shown, the adjusting assembly 30 includes an eccentric plate 31 fixed to one side of the rotating shaft 23 and the rotating shaft 231. Positioning rods 32 are fixed to the two eccentric plates 31 near their edges, away from the center. A fixing cylinder 33 is fixed to the inner wall of the mixing tank 21. An inlet 331 communicating with the inner wall of the mixing tank 21 is opened on the outer wall of the fixing cylinder 33. Several liquid outlets 332 are opened at the bottom of the fixing cylinder 33. An extrusion block 333 is slidably connected to the inner wall of the fixing cylinder 33. Two mounting brackets 34 are fixed to the top of the extrusion block 333. A connecting rod 341 is fixed between the two mounting brackets 34. A second set of rods 351 is rotatably connected to the outer periphery of the connecting rod 341. The outer periphery of the positioning rod 32... A first sleeve rod 35 is rotatably connected, and the first sleeve rod 35 and the second sleeve rod 351 are slidably connected through an adjusting member. The second sleeve rod 351 is slidably connected inside the first sleeve rod 35. The adjusting member includes a through groove 352 that is opened through one side of the first sleeve rod 35. An extension plate 353 that contacts the through groove 352 is fixed to one side of the second sleeve rod 351. A welding plate 354 is fixed to one side of the first sleeve rod 35, and an electric push rod 355 is installed between the welding plate 354 and the extension plate 353. A slot 36 is opened on the outer periphery of the fixed cylinder 33, and a sealing plate 361 is slidably connected to the inner wall of the slot 36. Several liquid outlets 332 are also opened on the surface of the sealing plate 361. To facilitate secondary treatment of residual oil and water in the sludge, while the rotating shaft 23 rotates, the adjusting component 30 drives the rotating shaft 231 to rotate synchronously. The rotating shaft 23 and the eccentric plate 31 on one side of the rotating shaft 231 perform eccentric rotational motion. Through the linkage of the positioning rod 32, the first sleeve rod 35, and the second sleeve rod 351, the extrusion block 333 is pushed to perform reciprocating linear extrusion motion on the inner wall of the fixed cylinder 33. After being stirred, the oily sludge is pushed by the rotating blades 24 and enters the interior of the fixed cylinder 33 through the feed port 331 on the outer wall of the fixed cylinder 33. The extrusion block 333 applies continuous extrusion pressure to the sludge. Under the pressure of the extrusion block 333, the free and emulsified water and oil phases in the oily sludge are squeezed out and seep out through the liquid outlet 332 on the bottom of the fixed cylinder 33 and the sealing plate 361, falling into the collection box 26 below. The sludge is trapped inside the fixed cylinder 33, realizing the secondary separation of oil and water and sludge. To facilitate the handling of oily sludge with different viscosities and oil contents, the extension plate 353 can be slid within the through groove 352 by activating the electric push rod 355 to change the length of the second rod 351 extending into the first rod 35, thereby adjusting the extrusion stroke and extrusion force of the extrusion block 333, improving material adaptability. The sludge after secondary extrusion is pressed into a sludge cake by the extrusion block 333. The sludge cake can be collected by pulling the sealing plate 361 and sliding it along the slot 36.

[0021] like Figure 2 , Figure 6 , Figure 7 , Figure 8 As shown, an actuating assembly 40 is provided between the rotating shaft 231 and the collection box 26. The actuating assembly 40 includes a reciprocating screw 41 rotatably connected inside the collection box 26. The reciprocating screw 41 and the outer periphery of the rotating shaft 231 are provided with gear grooves. The reciprocating screw 41 and the rotating shaft 231 are connected by a pulley 411. A fixing rod 42 is fixed to the inner wall of the collection box 26. A slider 43 is slidably connected to the outer periphery of the fixing rod 42. A rotating rod 44 is rotatably connected to the top of the slider 43. An embedded block 45 embedded in the reciprocating screw 41 is fixed to the top of the rotating rod 44. A connecting frame 46 is fixed to the bottom of the slider 43. A central rod 461 is fixed between the inner walls of the connecting frame 46. An actuating plate 462 is rotatably connected to the outer periphery of the central rod 461. An opening 47 is provided on one side of the collection box 26. An oil collection tank 48 is installed on one side of the collection box 26. To facilitate the separation of oil and water in the collection tank 26, as the rotating shaft 231 continues to rotate, the pulley 411 on the outer periphery of the rotating shaft 231 drives the reciprocating screw 41 inside the collection tank 26 to rotate synchronously. The embedded block 45 engages in the threaded groove of the reciprocating screw 41, causing the slider 43 to slide horizontally back and forth along the fixed rod 42. The connecting frame 46 at the bottom of the slider 43 drives the agitator plate 462 to move back and forth synchronously, continuously agitating the oil-water mixture in the collection tank 26. Utilizing the density difference between oil and water, during the agitation process, tiny oil droplets continuously collide, coalesce, and float to the surface to form an oil layer, while the water phase deposits in the lower layer of the collection tank 26. Figure 2 , Figure 7 As shown, when the agitator plate 462 moves to the left, it comes into contact with the oil and water in the collection box 26, causing the agitator plate 462 to press tightly against the connecting frame 46. The coalesced oil is agitated by the agitator plate 462, and the agitated oil flows into the oil collection tank 48 for recycling through the opening 47 on one side of the collection box 26. The water is discharged through the outlet 261 on one side of the collection box 26, thus achieving oil-water separation.

[0022] Working principle: When processing oily sludge, the material to be processed is put into the mixing tank 21 through the feed port 211 at the top of the mixing tank 21. Then the motor 22 is started, and its output end drives the rotating shaft 23 to rotate synchronously. The rotating blades 24 on the outer periphery of the rotating shaft 23 are in contact with the inner wall of the mixing tank 21 and rotate at high speed to fully mix and shear the oily sludge. On the one hand, it breaks the adsorption and adhesion state between the mud and sand particles and the oil phase, and breaks the stable oil-water emulsion system. During the mixing process, the oil and water can flow into the collection box 26 through the liquid outlet 25 to complete the initial oil-water separation. On the other hand, the rotating blades 24 can scrape off the sludge adhering to the wall of the mixing tank 21, push the sludge down and convey it forward, avoid material agglomeration and sticking to the wall, and ensure the smooth progress of subsequent processes. While the rotating shaft 23 rotates, the adjusting component 30 drives the rotating shaft 231 to rotate synchronously. The eccentric plate 31 performs eccentric rotational motion. Through the linkage transmission of the positioning rod 32, the first set of rods 35, and the second set of rods 351, the extrusion block 333 is pushed to perform reciprocating linear extrusion motion on the inner wall of the fixed cylinder 33. The stirred oily sludge is pushed by the rotating blades 24 and enters the cylinder through the feed port 331 on the outer wall of the fixed cylinder 33. The extrusion block 333 continuously applies pressure to the sludge, squeezing out the free and emulsified oil and water in the sludge. The oil and water seep into the collection box 26 below through the liquid outlet 332 on the bottom of the fixed cylinder 33 and the sealing plate 361. The sludge is trapped inside the fixed cylinder 33, realizing the secondary separation of oil and water and sludge, and further improving the separation effect. For oily sludge with different viscosities and oil content, the electric push rod 355 can be activated to extend and retract, causing the extension plate 353 to slide in the through groove 352, changing the length of the second rod 351 extending into the first rod 35, thereby adjusting the extrusion stroke and pressure of the extrusion block 333, enhancing the adaptability of the device to oily sludge with different viscosities and oil content. The sludge after secondary extrusion is pressed into a sludge cake. By pulling the sealing plate 361 along the slot 36, the sealing plate 361 can be pulled out and the formed sludge cake can be taken out, completing the sludge collection and sludge reduction. When the rotating shaft 231 continues to rotate, it drives the reciprocating screw 41 in the collection box 26 to rotate synchronously through the outer peripheral pulley 411. The inner block 45 is engaged in the thread groove of the reciprocating screw 41, which drives the slider 43 to slide horizontally back and forth along the fixed rod 42. The connecting frame 46 at the bottom of the slider 43 drives the agitator plate 462 to move synchronously, continuously agitating the oil-water mixture in the collection box 26. Utilizing the density difference between oil and water, tiny oil droplets collide, coalesce, and float to the surface during the agitation process to form an oil layer, while the water phase is deposited in the lower layer of the collection box 26. When the agitator plate 462 moves to the left, the plate surface is in close contact with the connecting frame 46 and pushes the oil layer to undulate. The coalesced oil flows into the oil collection tank 48 for recycling through the opening 47 on one side of the collection box 26, and the water phase is discharged through the outlet 261, ultimately achieving fine separation of oil and water.
