DETAILED DESCRIPTION

[0032] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0033] In order to facilitate the simultaneous and parallel processing of different parts of sludge, quickly digest a large amount of sludge, and shorten the overall processing time, as an embodiment of the present invention, Figure 1 , Figure 2As shown, an oil sludge separation device for an oil depot described in the present invention comprises a cylinder 1, a separation component is rotatably connected to the outer side of the cylinder 1, a driving structure for driving the separation component to rotate is provided inside the cylinder 1, an oil discharge component is provided on the upper part of the separation component, a multi-stage discharge component is provided on one side of the lower part of the separation component, a discharge drive component for driving the oil discharge component to move downward and driving the multi-stage discharge component to dock with the separation component is provided inside the cylinder 1, and a multi-stage aggregate structure with an opening upward is provided at the lower part of the cylinder 1.

[0034] When in use, the oil sludge to be processed is injected into the separation component, and then the driving structure is turned on. The driving structure drives the separation component to rotate, and the oil sludge begins to separate under the action of centrifugal force. The density of oil is relatively small, and it will gradually float to the upper layer of the liquid in the separation component. The density of water is second, and it is located in the middle layer. The density of mud is the largest, and it is precipitated at the bottom of the separation component. In this way, the separation of oil sludge is completed, which is convenient for processing different parts of oil sludge in parallel at the same time, quickly digesting a large amount of oil sludge, and shortening the overall processing time;

[0035] Afterwards, the discharge drive assembly is started to drive the oil discharge assembly downward so that the oil discharge assembly contacts and extracts the oil in the upper layer of the separation assembly to complete the oil discharge operation. The discharge drive assembly continues to work to drive the multi-stage discharge assembly to move so that it docks with the separation assembly. The water and mud in the lower layer of the separation assembly enter the multi-stage discharge assembly, and the water and mud are discharged through corresponding channels respectively. The multi-stage aggregate structure collects the water and mud discharged from the multi-stage discharge assembly.

[0036] In order to facilitate the separation of oil sludge, for example, Figure 2 , Figure 3 , Figure 4 As shown, the present invention also includes that the separation assembly includes a rotating ring 2 rotatably connected to the upper end of the cylinder body 1, the inner side of the rotating ring 2 is provided with a tooth structure 3, the driving structure is meshed with the tooth structure 3 for transmission, the outer side of the rotating ring 2 is provided with a plurality of groups of circumferentially distributed separation cylinders 4, the separation cylinders 4 are open upward, the outer side of the separation cylinder 4 is hinged with a support rod 6 through a damping hinge shaft 5, and the end of the support rod 6 away from the damping hinge shaft 5 is fixedly connected to the outer side of the rotating ring 2.

[0037] When in use, the oil sludge is injected into the separation cylinder 4 through a suitable feeding device. Since the separation cylinders 4 are distributed circumferentially, multiple separation cylinders 4 can be fed at the same time to improve the feeding efficiency. The driving structure that meshes with the tooth structure 3 of the rotating ring 2 is started, and the driving structure drives the rotating ring 2 to rotate, thereby causing the separation cylinder 4 to make a circular motion around the cylinder body 1. When the rotation of the separation cylinder 4 reaches a certain degree, the centrifugal force exerted on the separation cylinder 4 is converted into an outward expansion and swinging force through the damping hinge shaft 5. Relying on the damping hinge shaft 5, the separation cylinder 4 will expand and swing outward at a relatively stable speed. During the rotation process, the oil sludge in the separation cylinder 4 is acted upon by the centrifugal force, which further promotes the separation effect of oil, water and mud. The rotation speed of the driving structure can be adjusted according to actual conditions, thereby changing the size of the centrifugal force and indirectly adjusting the swing amplitude of the separation cylinder 4 to achieve the best separation effect. When the separation operation is completed, the driving structure is stopped to stop the rotation of the separation cylinder 4, and the subsequent process of the overall device is followed to discharge oil, discharge materials and other operations.

[0038] In order to facilitate the rotation of the separation cylinder 4, for example, Figure 3 , Figure 4 , Figure 8 As shown, the present invention also includes that the driving structure includes a driving motor 7 arranged inside the cylinder 1, the fixed end of the driving motor 7 is fixedly connected to the inner wall of the cylinder 1 through a support plate, and the output end of the driving motor 7 is fixedly connected to a driving gear 8, and the driving gear 8 is meshed with the tooth structure 3 for transmission.

[0039] When in use, the power supply of the driving motor 7 is turned on, the driving motor 7 is started, and the motor output shaft drives the driving gear 8 to rotate. The rotating driving gear 8 is meshed with the tooth structure 3 on the inner side of the rotating ring 2 of the separation component. The rotational power of the driving gear 8 is transmitted to the rotating ring 2. The rotating ring 2 starts to rotate around the axis of the cylinder 1 driven by the driving gear 8, and then drives the separation cylinder 4 connected to the outer side of the rotating ring 2 to rotate synchronously. At this time, the sludge in the separation cylinder 4 starts to be separated under the action of centrifugal force.

[0040] In order to facilitate the discharge of mud and water in the separation cylinder 4, for example, Figure 3 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig.11As shown, the present invention also includes that the multi-stage discharge assembly includes a fixed cylinder 9 horizontally arranged on one side of the separation cylinder 4, the fixed cylinder 9 is fixedly connected to the inner wall of the cylinder body 1 through a connecting rod 10, a horizontally arranged spiral feeding rod 11 is arranged inside the fixed cylinder 9, and a threaded hole is arranged at one end of the spiral feeding rod 11 away from the separation cylinder 4, and a driving shaft 12 is threadedly connected in the threaded hole, and one end of the driving shaft 12 away from the spiral feeding rod 11 passes through the fixed cylinder 9 and is rotatably connected to the fixed cylinder 9, and the other end of the driving shaft 12 is fixedly connected to a first bevel gear 13, and the first bevel gear 13 is meshed with the discharge drive assembly for transmission;

[0041] A sliding hole 14 corresponding to the fixed cylinder 9 is provided at the bottom of the separation cylinder 4, and a sliding column 15 is sealed and slidably connected in the sliding hole 14. A magnet 16 magnetically attracted to the sliding column 15 is installed at one end of the spiral feeding rod 11 close to the sliding column 15, and a discharge port 17 connected to the sliding hole 14 is provided at the bottom of the inner side of the separation cylinder 4; a magnetic ring 18 is installed on the edge of one side of the sliding hole 14 close to the fixed cylinder 9, and the magnetic ring 18 is magnetically attracted to the end of the fixed cylinder 9, and a plurality of groups of drainage holes 19 are provided on one side of the lower part of the fixed cylinder 9, and a mud discharge port 20 is provided on one side of the drainage hole 19, and the multi-stage aggregate structure is located below the fixed cylinder 9.

[0042] When in use, after the separation operation is completed, the driving motor 7 is turned off, and the separation cylinder 4 stops rotating. The magnetic adsorption effect between the magnetic ring 18 and the end of the fixed cylinder 9 ensures the stability of the relative position of the fixed cylinder 9 and the separation cylinder 4, so as to prepare for the subsequent discharge work.

[0043] The discharging drive assembly is turned on, and the discharging drive assembly drives the first bevel gear 13 meshing therewith to rotate, thereby causing the driving shaft 12 to rotate rapidly. When the driving shaft 12 starts to rotate, since the threaded hole of the spiral feeding rod 11 is threadedly connected to the driving shaft 12, and the spiral feeding rod 11 is difficult to quickly rotate synchronously with the driving shaft 12, the spiral feeding rod 11 moves horizontally toward the separation cylinder 4 in the fixed cylinder 9. At the same time, relying on the positioning effect of the magnetic ring 18 and the magnetic adsorption of the end of the fixed cylinder 9, the spiral feeding rod 11 can accurately move toward the sliding column 15 to avoid being unable to effectively dock with the sliding column 15 due to position deviation. The magnet 16 at one end of the spiral feeding rod 11 close to the sliding column 15 moves with the spiral feeding rod 11, approaches and adsorbs the sliding column 15, causes the sliding column 15 to slide in the sliding hole 14, and opens the discharge port 17 at the bottom of the separation cylinder 4;

[0044] The mud and water separated in the lower layer of the separation cylinder 4 can smoothly enter the fixed cylinder 9 through the discharge port 17. At the same time, the adsorption effect of the magnetic ring 18 can also effectively prevent the mud and water from leaking from the gap between the separation cylinder 4 and the fixed cylinder 9 during the discharge process. The mud that enters the fixed cylinder 9 first will be discharged through the mud discharge port 20, and the water that enters later will be discharged through the drainage hole 19. Similarly, for the mud-water mixture that enters the fixed cylinder 9, the water will be discharged through the drainage hole 19 on the lower side. The mud moves to the mud discharge port 20 under the push of the continuous rotation of the spiral feeding rod 11. The magnetic ring 18 continues to play a positioning and sealing role, stabilizes the connection between the fixed cylinder 9 and the separation cylinder 4, and avoids the pressure and vibration during the discharge process causing the position of the two to change, affecting the smoothness of the discharge and the separation effect.

[0045] The water discharged from the drainage hole 19 and the mud discharged from the mud discharge port 20 fall into the corresponding areas of the multi-level aggregate structure below for subsequent centralized treatment;

[0046] It should be pointed out that, when the mud, water and oil have been stratified, the mud at the bottom of the separation cylinder 4 is discharged first, which can accurately give priority to the mud with the highest density, effectively reduce the situation where the mud is re-mixed into the water body during the subsequent drainage process, and ensure the purity of the drainage. When the mud is basically discharged, there is mainly water and a small amount of residual oil in the fixed cylinder 9 and the separation cylinder 4. At this time, drainage operation can effectively improve the purity of the discharged water and improve the work efficiency of discharge.

[0047] In order to facilitate the discharge of the oil in the separation cylinder 4, for example, Figure 2 , Figure 3 As shown, the present invention also includes that the oil discharge assembly includes a first floating plate 21 horizontally arranged above the separation cylinder 4, and the upper surface of the first floating plate 21 is fixedly connected with a plurality of groups of vertically arranged sliding rods 22, and the upper ends of the sliding rods 22 are fixedly connected with limiting blocks 23, and the sliding rods 22 are slidably connected with a second floating plate 24, and the upper surface of the second floating plate 24 is provided with a vertically arranged oil discharge pipe 25, and the lower end of the oil discharge pipe 25 passes through the second floating plate 24, and the upper end of the oil discharge pipe 25 is provided with a flange 26, and the discharge drive assembly is used to drive the oil discharge pipe 25 to move up and down.

[0048] When in use, after the separation operation is completed, the drive motor 7 is turned off, and then the discharge drive assembly is turned on. When the oil sludge in the separation cylinder 4 is separated and the oil layer is located at the upper layer, the discharge drive assembly drives the oil discharge pipe 25 and the first floating plate 21 to move downward. When the first floating plate 21 moves down to a certain position, the first floating plate 21 is located between the oil and the water.

[0049] The discharge pipe is connected by the flange 26. When the lower end of the oil discharge pipe 25 enters the oil layer, the oil is discharged through the oil discharge pipe 25 and the external discharge pipe connected by the flange 26. During the oil discharge process, the first floating plate 21 effectively reduces the mixing of tiny particles and impurities in the lower water body into the oil. As the oil layer height decreases, a stable separation state is maintained between the oil and the water body, avoiding the oil discharge pipe 25 from sucking in the water body due to the violent fluctuation of the oil-water interface, thereby ensuring the continuity and stability of oil discharge.

[0050] When the oil in the separation cylinder 4 is basically drained, the lower end of the oil drain pipe 25 contacts the first floating plate 21, and the first floating plate 21 is adsorbed on the lower end of the oil drain pipe 25, thereby automatically cutting off the oil inlet of the oil drain pipe 25; then the discharge drive assembly is controlled to drive the oil drain pipe 25 to move upward to leave the separation cylinder 4. After the oil drain pipe 25 returns to the initial position, the discharge drive assembly and the external discharge pipeline are closed, and the second floating plate 24 will automatically fall and return to the initial position to prepare for the next oil discharge operation.

[0051] For example, Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 8 As shown, the present invention also includes that the discharge drive assembly includes a double-axis motor 27 vertically arranged inside the cylinder 1, the upper end of the double-axis motor 27 is provided with a first output shaft 28, the lower end of the double-axis motor 27 is provided with a second output shaft 29, the outer side of the oil discharge pipe 25 is fixedly connected with a rotating plate 30, the end of the rotating plate 30 away from the oil discharge pipe 25 is fixedly connected with a rotating drum 31, the upper end of the first output shaft 28 is provided with a threaded structure 32, the rotating drum 31 is threadedly connected with the threaded structure 32, the inner side of the cylinder 1 is fixedly connected with a vertically arranged telescopic rod 33, and the upper end of the telescopic rod 33 is fixedly connected with the rotating plate 30;

[0052] The lower end of the second output shaft 29 is fixedly connected with a second bevel gear 34 , and the second bevel gear 34 is meshed with the first bevel gear 13 for transmission; the outer side of the dual-axis motor 27 is fixedly connected to the inner wall of the cylinder 1 through a plurality of sets of fixing rods.

[0053] When in use, the oil sludge is separated in the separation cylinder 4. When oil and material discharge operations are required, the double-axis motor 27 is started, and the first output shaft 28 of the double-axis motor 27 starts to rotate. Since the rotating cylinder 31 is threadedly connected to the threaded structure 32 of the first output shaft 28, and the rotating plate 30 is guided and restricted by the telescopic rod 33, the rotation of the first output shaft 28 will drive the rotating cylinder 31 to drive the rotating plate 30 and the oil discharge pipe 25 to move downward along the direction of the telescopic rod 33, and the oil discharge pipe 25 gradually approaches the oil layer in the separation cylinder 4. When the lower end of the oil discharge pipe 25 enters the oil layer, the oil discharge operation can be started. During the oil discharge process, the first floating plate 21 and the second floating plate 24 can change according to the oil level, so that the oil discharge pipe 25 is always in the oil layer, ensuring efficient oil discharge.

[0054] The second output shaft 29 of the dual-axis motor 27 rotates synchronously, driving the second bevel gear 34 at its lower end to rotate. The rotating second bevel gear 34 meshes with the first bevel gear 13 for transmission, so that the first bevel gear 13 drives the driving shaft 12 to rotate. When the driving shaft 12 rotates, it cooperates with the threaded hole of the spiral feeding rod 11 to push the spiral feeding rod 11 to move horizontally toward the separation cylinder 4 in the fixed cylinder 9. The magnet 16 at one end of the spiral feeding rod 11 close to the sliding column 15 absorbs the sliding column 15, so that the sliding column 15 slides in the sliding hole 14, opens the discharge port 17 at the bottom of the separation cylinder 4, realizes the docking of the multi-stage discharge assembly with the separation cylinder 4, and then discharges the mud and water in the lower layer of the separation cylinder 4 into the fixed cylinder 9 for subsequent treatment;

[0055] After the oil discharge operation is completed, the dual-axis motor 27 is driven to rotate in the reverse direction. At this time, the first output shaft 28 of the dual-axis motor 27 rotates in the reverse direction. The rotation of the first output shaft 28 drives the rotating drum 31 to drive the rotating plate 30 and the oil discharge pipe 25 to reset upward along the direction of the telescopic rod 33, so that the first floating plate 21 leaves the separation drum 4 and returns to the initial state.

[0056] After the discharge work after the oil sludge separation is completed, in order to restore the device to its initial state for the next operation, the dual-axis motor 27 is started. At this time, the second output shaft 29 of the dual-axis motor 27 rotates in the opposite direction, and drives the second bevel gear 34 to rotate in the opposite direction. The reverse rotation of the second bevel gear 34 drives the first bevel gear 13 to rotate in the opposite direction, thereby driving the screw feeding rod 11 to reset and move. When the screw feeding rod 11 resets and moves, it relies on the magnet 16 to drive the sliding column 15 to reset and move to the initial state, and relies on the sliding column 15 to close the discharge port 17, so as to prepare for the next oil sludge separation and discharge operation.

[0057] For example, Figure 2 , Fig. 9 , Fig.10 , Fig.11As shown, the present invention also includes that the multi-stage aggregate structure includes a sleeve 35 opening upward, and a first storage bin 36 and a second storage bin 37 are provided in the sleeve 35, the first storage bin 36 is located below the drainage hole 19 and corresponds to the drainage hole 19, the second storage bin 37 is located below the mud discharge port 20 and corresponds to the mud discharge port 20, and a first discharge pipe 38 connected to the first storage bin 36 and a second discharge pipe 39 connected to the second storage bin 37 are provided at the bottom of the sleeve 35.

[0058] During use, when the oil-sludge separation device is running, the drainage hole 19 of the fixed cylinder 9 starts to drain water and the mud discharge port 20 starts to discharge mud, the water will directly fall into the first storage bin 36, and the mud will fall into the second storage bin 37. When the water in the first storage bin 36 or the mud in the second storage bin 37 accumulates to a certain amount and needs to be discharged, the valve of the first discharge pipe 38 is opened to discharge the water in the first storage bin 36 for subsequent treatment. Similarly, the valve of the second discharge pipe 39 is opened to discharge the mud in the second storage bin 37. After the discharge is completed, the valves of the first discharge pipe 38 and the second discharge pipe 39 are closed.

[0059] For example, Figure 1 As shown, the present invention also includes that a first fixing ring 40 and a second fixing ring 41 are horizontally arranged on the outer side of the separation component, the second fixing ring 41 is located below the first fixing ring 40, a plurality of groups of circumferentially distributed arc frames 42 are fixedly connected between the first fixing ring 40 and the second fixing ring 41, and a load-bearing leg 43 is fixedly connected to the lower surface of the second fixing ring 41.

[0060] When in use, the outer side of the separation cylinder 4 may collide with other surrounding equipment and components during the swinging process. The arc frame 42 is located between the first fixing ring 40 and the second fixing ring 41 and is distributed circumferentially on the outer side of the separation cylinder 4, thereby effectively protecting the separation cylinder 4 itself and surrounding equipment.

[0061] For example, Figure 2 , Figure 3 , Figure 4 As shown, the present invention also includes that a plurality of groups of support legs 44 are provided at the bottom of the sleeve 35, a plurality of groups of circumferentially distributed diagonal support rods 45 are fixedly connected between the lower surface of the cylinder body 1 and the upper part of the sleeve 35; and reinforcing rods 46 are fixedly connected between adjacent support rods 6.

[0062] When in use, the overall stability of the sleeve 35 can be ensured by relying on several groups of supporting legs 44 at the bottom of the sleeve 35; several groups of circumferentially distributed oblique support rods 45 are installed between the lower surface of the cylinder 1 and the upper part of the sleeve 35 to effectively enhance the structural stability between the cylinder 1 and the sleeve 35; reinforcing rods 46 are installed between adjacent supporting rods 6, and the reinforcing rods 46 should be tightly connected to the supporting rods 6 to further enhance the stability of the entire structure and prevent deformation due to uneven force during use.

[0063] When the present invention is used, the sludge to be treated is injected into the separation cylinder 4 in a suitable manner. Since the separation cylinder 4 is opened upward and there are multiple groups, multiple separation cylinders 4 can be fed at the same time, thereby improving the feeding efficiency.

[0064] The driving motor 7 is turned on, and the driving motor 7 drives the driving gear 8 to rotate. The driving gear 8 meshes with the tooth structure 3 on the inner side of the rotating ring 2 for transmission, thereby driving the rotating ring 2 and the separation cylinder 4 connected to the outer side of the rotating ring 2 to rotate around the cylinder body 1. Under the action of centrifugal force and the additional force generated by the swing of the separation cylinder 4, the oil, water and mud in the sludge will be efficiently separated in the separation cylinder 4. The density of oil is relatively small and will gradually float to the upper layer of the liquid in the separation component. The density of water is second and is located in the middle layer. The density of mud is the largest and is deposited at the bottom of the separation cylinder 4, thereby completing the separation of oil sludge;

[0065] When the separation operation is completed, the driving motor 7 is turned off, and the separation cylinder 4 stops rotating. The magnetic adsorption effect between the magnetic ring 18 and the end of the fixed cylinder 9 ensures the stability of the relative position between the fixed cylinder 9 and the separation cylinder 4, so as to prepare for the subsequent discharge work.

[0066] The dual-axis motor 27 is started, and the first output shaft 28 of the dual-axis motor 27 rotates. Since the rotating cylinder 31 on the rotating plate 30 outside the oil drain pipe 25 is threadedly connected with the threaded structure 32 of the first output shaft 28, and the rotating plate 30 is guided and restricted by the telescopic rod 33, the first output shaft 28 will drive the oil drain pipe 25 to move downward when it rotates. As the oil drain pipe 25 moves downward, when the lower end of the oil drain pipe 25 contacts the oil in the upper layer of the separation cylinder 4, the oil will be discharged through the oil drain pipe 25. During the oil discharge process, the first floating plate 21 and the second floating plate 24 can slide on the sliding rod 22 according to the change of the oil level, ensuring that the oil drain pipe 25 can always be in the oil layer and the oil can be discharged efficiently. At the same time, the first floating plate 21 can effectively prevent the small particles and impurities in the lower water body from mixing into the oil, reducing the risk of inhaling impurities in the water body, and ensuring that the lower end of the oil drain pipe 25 can be accurately positioned at the oil layer with higher purity.

[0067] The second output shaft 29 of the dual-shaft motor 27 rotates, driving the second bevel gear 34 to rotate. The second bevel gear 34 meshes with the first bevel gear 13 to drive the drive shaft 12 to rotate. When the drive shaft 12 rotates, the screw feeding rod 11 is driven to move horizontally in the fixed cylinder 9 through the threaded connection. When the screw feeding rod 11 moves toward the separation cylinder 4, the sliding column 15 is pushed to slide in the sliding hole 14 at the bottom of the separation cylinder 4, opening the discharge port 17 at the bottom of the separation cylinder 4. The mud and water in the lower layer of the separation cylinder 4 can enter the fixed cylinder 9 through the discharge port 17, and the mud is discharged from the mud discharge port 20 under the push of the screw feeding rod 11, and the water is discharged through the drainage hole 19;

[0068] When the mud, water and oil have been separated into layers, the mud at the bottom of the separation cylinder 4 is first discharged, and the mud with the highest density is treated first, which effectively reduces the situation where the mud is mixed into the water body again during the subsequent drainage process, and ensures the purity of the drainage. When the mud is basically discharged, the fixed cylinder 9 and the separation cylinder 4 mainly have water and a small amount of residual oil. At this time, the drainage operation can effectively improve the purity of the discharged water and improve the working efficiency of the discharge.

[0069] The first storage bin 36 is located below the drainage hole 19 and is used to collect water discharged from the drainage hole 19. The second storage bin 37 is located below the mud discharge port 20 and is used to collect mud discharged from the mud discharge port 20. After a certain amount of mud is collected, the water and mud can be discharged through the first discharge pipe 38 and the second discharge pipe 39 at the bottom of the sleeve 35 for subsequent treatment.
