Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, and in particular to an oily wastewater treatment device for boat cleaning. Background Technology

[0002] During the cleaning of boats and ships, oily wastewater, which is a mixture of oil and water, is usually generated. In order to protect the marine environment and avoid pollution of the sea, oily wastewater must be treated by oily wastewater treatment equipment before it is discharged into the sea.

[0003] Currently, most oily wastewater treatment equipment simply separates oil from water. However, oily wastewater contains volatile oils, such as gasoline and other combustion oils. Oil-water separation wastewater treatment methods cannot treat the high-risk mixtures generated by oil volatilization, which can easily lead to safety hazards during the oily wastewater treatment process. Summary of the Invention

[0004] This invention discloses an oily wastewater treatment device for boat cleaning, which helps to ensure safety during the oily wastewater treatment process.

[0005] The present invention provides an oily wastewater treatment device for ship cleaning, which adopts the following technical solution:

[0006] An oily wastewater treatment device for boat cleaning includes an oily wastewater treatment tank, an oily wastewater evaporation mechanism, and an oil-water separation mechanism. The oily wastewater evaporation mechanism includes an evaporation box disposed within the oily wastewater treatment tank and a heating element disposed within the evaporation box. An input pipe for inputting oily wastewater is connected to the evaporation box. The heating element is used to heat the oily wastewater in the evaporation box. A gas collection box is disposed within the oily wastewater treatment tank. The evaporation box and the gas collection box are connected via a gas delivery pipe. An output pipe for conveying the heated oily wastewater to the oil-water separation mechanism is connected to the evaporation box. The oil-water separation mechanism is used to separate oil and water in the heated and evaporated oily wastewater. An adjusting plate for opening and closing the outlet of the output pipe is slidably disposed within the evaporation box. A shape memory metal strip is disposed between the adjusting plate and the evaporation box. When the temperature of the shape memory metal strip is less than a preset value, the adjusting plate abuts against the outlet of the output pipe to close the output pipe. When the temperature of the shape memory metal strip is greater than or equal to the preset value, the shape memory metal strip deforms, causing the adjusting plate to move away from the output pipe.

[0007] Furthermore, the adjusting plate is a float plate, the density of the adjusting plate is greater than the density of water, and the buoyancy of the adjusting plate is less than the elasticity of the shape memory metal strip.

[0008] Furthermore, a rotating rod is rotatably arranged inside the evaporation chamber, and multiple stirring blades are arranged on the rotating rod along its circumference. The evaporation chamber is provided with a drive source for driving the rotating rod to rotate.

[0009] Furthermore, the oil-water separation mechanism includes an oil-water separation tank disposed within the oily wastewater treatment tank, a partition disposed within the oil-water separation tank, an oil-water separation membrane disposed on the partition, and a pushing component disposed within the oil-water separation tank. The partition divides the oil-water separation tank into a treatment chamber and a water storage chamber. The treatment chamber is connected to the end of the output pipe away from the evaporation chamber. An opening is provided on the partition, and the oil-water separation membrane covers the opening. The pushing component is disposed within the treatment chamber and is used to squeeze the water in the oily wastewater within the treatment chamber into the water storage chamber.

[0010] Furthermore, the pushing component includes an oily wastewater treatment plate slidably disposed in the treatment chamber and a driving member disposed in the treatment chamber. The sliding direction of the oily wastewater treatment plate is perpendicular to the plane of the oil-water separation membrane, and the driving member is used to drive the oily wastewater treatment plate to slide in a direction closer to or away from the oil-water separation membrane.

[0011] Furthermore, the oily wastewater treatment plate has through holes, and a cleaning frame is installed inside the through holes. An installation strip is slidably installed on the side of the oily wastewater treatment plate near the oil-water separation membrane. The sliding direction of the installation strip is perpendicular to the sliding direction of the oily wastewater treatment plate. An adjustment member is provided on the oily wastewater treatment plate for adjusting the sliding direction of the installation strip towards or away from the cleaning frame. A closing plate is rotatably installed on the installation strip for blocking or opening the cleaning frame. The rotation axis of the closing plate is perpendicular to the sliding direction of the oily wastewater treatment plate. An elastic member is provided on the installation strip for driving the closing plate to rotate towards the oily wastewater treatment plate.

[0012] Furthermore, the adjusting component includes a sliding rod slidably passing through the oily wastewater treatment plate, a connecting plate disposed on the sliding rod, a connecting rod hinged to the connecting plate, and a spring sleeved on the sliding rod. The sliding direction of the sliding rod is parallel to the sliding direction of the oily wastewater treatment plate. The sliding rod is located on the side of the mounting strip closer to the impurity removal frame. The connecting plate is located at the end of the sliding rod closer to the oil-water separation membrane. The end of the connecting rod away from the connecting plate is hinged to the mounting strip. The hinge axis of the connecting rod is perpendicular to the sliding direction of the mounting strip. The distance from the connecting rod to the oily wastewater treatment plate increases along the direction of the mounting strip closer to the connecting plate. One end of the spring is disposed on the adjusting plate, and the other end is disposed on the oily wastewater treatment plate. The spring is used to push the adjusting plate to slide towards the side closer to the oil-water separation membrane. When the spring is in its natural state, the closing plate is aligned with the impurity removal frame.

[0013] Furthermore, the sealing plate is provided with a rotating shaft, which is rotatably mounted on the mounting strip. The elastic element includes a torsion spring for driving the sealing plate to rotate toward the direction of the oily wastewater treatment plate. The torsion spring is sleeved on the rotating shaft, with one end of the torsion spring mounted on the mounting strip and the other end mounted on the sealing plate.

[0014] Furthermore, the upper surface of the output pipe is higher than the bottom wall of the evaporation chamber, and a filter screen is provided at the opening of the output pipe.

[0015] The oily wastewater treatment equipment for ship cleaning described in this application has at least the following beneficial effects:

[0016] 1. In use, oily wastewater generated from boat cleaning is pumped into the evaporation chamber. Since the oily wastewater is at room temperature at this time, the regulating plate and the memory metal strip are in their initial state, so that the regulating plate closes the outlet of the output pipe. Then, the oily wastewater in the evaporation chamber is heated by the heating element, so that the volatile oil in the oily wastewater enters the gas collection box for storage. When the temperature of the oily wastewater is greater than or equal to the preset value, the memory metal strip gradually deforms. The deformation of the memory metal strip supports the regulating plate, so that the regulating plate opens the output pipe. Then, the heated oily wastewater in the evaporation chamber enters the oil-water separation mechanism. Then, the oil-water separation mechanism separates the oil and water in the oily wastewater for separate subsequent treatment, which helps to protect the marine environment and avoid pollution of the sea water. Because the volatile oil in the oily wastewater is collected and treated before oil-water separation, it helps to ensure the safety of the oily wastewater treatment process.

[0017] 2. When all the oily wastewater flows to the side of the oily wastewater treatment plate closest to the partition, the sealing plate, under the action of the torsion spring, blocks the impurity removal frame. Then, the driving component drives the oily wastewater treatment plate to slide towards the partition. Since the through hole is closed at this time, as the oily wastewater treatment plate is squeezed, neither oil nor water in the oily wastewater can pass through the through hole. At this time, the water in the oily wastewater can only enter the water storage chamber through the oil-water separation membrane, thus greatly improving the oily wastewater separation and treatment effect. As the water in the oily wastewater gradually enters the water storage chamber, the resistance to the continued movement of the oily wastewater treatment plate increases. Then, the oil will exert a reverse force on the connecting plate, driving the connecting plate and the sliding rod to move away from the partition relative to the oily wastewater treatment plate. Then, through the linkage transmission, the mounting strip moves away from the through hole, and the sealing plate gradually opens the through hole. As the oily wastewater treatment plate continues to approach the partition, the oil enters the side of the oily wastewater treatment plate away from the partition through the impurity removal frame, thus achieving oil-water impurity removal and efficient separation, which helps to protect the marine environment and avoid pollution of marine waters.

[0026] The following combination Figures 1-6 The present invention will be described in further detail below.

[0027] This invention discloses an oily wastewater treatment device for boat cleaning. (Refer to...) Figure 1 and Figure 2The oily wastewater treatment equipment for boat cleaning includes an oily wastewater treatment tank 1, an oily wastewater evaporation mechanism, and an oil-water separation mechanism. To facilitate the movement of the oily wastewater treatment equipment, the oily wastewater treatment tank 1 is fixedly installed on a movable vehicle body 30. An inspection door 31 is installed on the side wall of the oily wastewater treatment tank 1, which facilitates the inspection and cleaning of the interior of the oily wastewater treatment tank 1. The oily wastewater evaporation mechanism includes an evaporation box 2 and a heating element. The evaporation box 2 is fixedly installed inside the oily wastewater treatment tank 1 and is located at the upper end of the interior of the oily wastewater treatment tank 1. The upper end of the evaporation box 2 is connected to an input pipe 3 for inputting oily wastewater. Specifically, the input pipe 3 passes through the oily wastewater treatment tank 1 and is connected to an external suction pump body. The external suction pump body can pump the oily wastewater generated by boat cleaning into the evaporation box 2.

[0028] Reference Figure 2 A heating element is installed inside the evaporation chamber 2 to heat the oily wastewater inside. A gas collection box 4 is fixedly installed inside the oily wastewater treatment tank 1, located on the horizontal side of the evaporation chamber 2. The evaporation chamber 2 and the gas collection box 4 are connected by a gas delivery pipe 5. To facilitate the collection of volatile oils, the gas delivery pipe 5 is connected to the upper end of the evaporation chamber 2, and a one-way valve is installed on the gas delivery pipe 5 to ensure that volatile oils can only enter the gas collection box 4 from the evaporation chamber 2 without backflow. A conveying pipe (not shown in the figure) for discharging volatile oils is connected to the gas collection box 4. The conveying pipe passes through the oily wastewater treatment tank 1 and is equipped with a valve.

[0029] Reference Figure 2 and Figure 3The bottom wall of the evaporation chamber 2 is connected to an output pipe 6 for conveying the heated oily wastewater to the oil-water separation mechanism. The output pipe 6 extends downward and is also equipped with a one-way valve. The oil-water separation mechanism is used to separate the heated oily wastewater from the oil. An adjusting plate 7 for opening and closing the outlet of the output pipe 6 is slidably installed inside the evaporation chamber 2. The adjusting plate 7 is slidably installed in the vertical direction and is offset from the input pipe 3 so that the oily wastewater entering the evaporation chamber 2 will not flow directly onto the adjusting plate 7. A shape memory metal strip 8 is installed between the adjusting plate 7 and the bottom wall of the evaporation chamber 2. When the temperature of the shape memory metal strip 8 is less than a preset value, the shape memory metal strip 8 is bent and the adjusting plate 7 abuts against the outlet of the output pipe 6 to seal the output pipe 6. Specifically, when the temperature of the shape memory metal strip 8 is less than the preset value, it is S-shaped. One end of the shape memory metal strip 8 is fixed to the bottom wall of the evaporation chamber 2, and the other end is fixed to the side of the adjusting plate 7 near the output pipe 6. When the temperature of the shape memory metal strip 8 is greater than or equal to a preset value, the shape memory metal strip 8 deforms, causing the adjusting plate 7 to move away from the output tube 6. In this embodiment of the invention, the preset value is 50°C. At 50°C, the shape memory metal strip 8 deforms into a vertical straight line. The shape memory metal strip 8 can be made of nickel-titanium alloy, which is a two-way shape memory metal. To improve the adjustment effect, multiple shape memory metal strips 8 can be set as needed. In other embodiments, the preset value can be other values ​​as needed, such as 60°C.

[0030] In operation, an external suction pump draws oily wastewater generated during ship cleaning into the evaporation chamber 2 via the input pipe 3. Since the wastewater is at room temperature, the regulating plate 7 and the shape memory metal strip 8 are in their initial state (the strip 8 is bent into an S-shape). The regulating plate 7 closes the outlet pipe 6, allowing the oily wastewater to be stored within the evaporation chamber 2. The heating element then heats the wastewater. As the temperature rises, volatile oils in the wastewater enter the gas collection box 4 via the upper gas delivery pipe 5 for centralized processing. As the temperature of the wastewater in the evaporation chamber 2 increases, when the temperature reaches a certain level... At the preset value, the shape memory metal strip 8 gradually deforms, supporting the adjustment plate 7 and causing it to move away from the output pipe 6, opening the output pipe 6. Then, the heated oily wastewater in the evaporation chamber 2 enters the oil-water separation mechanism through the output pipe 6. The oil-water separation mechanism separates the oil and water in the oily wastewater, allowing for separate treatment of the oil and discharge of qualified water, thus helping to protect the marine environment and avoid pollution of the sea. Because the volatile oil in the oily wastewater is collected and treated before oil-water separation, it helps to ensure the safety of the oily wastewater treatment process.

[0031] Reference Figure 3To facilitate heating of the oily wastewater inside the evaporation chamber 2, a heating element includes a heating tube 32, which is fixedly installed on the bottom wall of the evaporation chamber 2. Heating of the oily wastewater inside the evaporation chamber 2 can be achieved by activating the heating tube 32. In other embodiments, the heating tube 32 can be replaced with a heating wire.

[0032] Reference Figure 3 To facilitate the installation of the memory metal strip 8, the upper surface of the output pipe 6 is higher than the bottom wall of the evaporation chamber 2. Specifically, the distance between the upper surface of the output pipe 6 and the bottom wall of the evaporation chamber 2 is less than 5mm. This allows large solid particles in the oily wastewater drawn into the evaporation chamber 2 to settle on the bottom wall of the evaporation chamber 2 under gravity, making it less likely for them to enter the oil-water separation mechanism through the output pipe 6. A filter screen 29 is fixedly installed at the outlet of the output pipe 6 to facilitate preliminary filtration of the oily wastewater.

[0033] Reference Figure 3 Furthermore, the regulating plate 7 is a high-temperature resistant float. The density of the regulating plate 7 is greater than that of water, and the buoyancy of the regulating plate 7 is less than the elasticity of the shape memory metal strip 8. By using a float for the regulating plate 7, when the shape memory metal strip 8 deforms, the regulating plate 7 can move upward under its own buoyancy, which helps to ensure that the regulating plate 7 can rise to open the output pipe 6 and reduce the resistance to the deformation of the shape memory metal strip 8.

[0034] Reference Figure 3 Inside the evaporation chamber 2, a rotating rod 9 is rotatably mounted. The rotating rod 9 is located above the adjusting plate 7, and the rotation axis of the rotating rod 9 is set in the horizontal direction. Multiple stirring blades 10 are fixed on the rotating rod 9 along its circumference. The distance from the side of the stirring blade 10 away from the rotating rod 9 to the rotating rod 9 is less than the distance from the adjusting plate 7 to the rotating rod 9 after it is raised, so that the stirring blades 10 will not affect the rise of the adjusting plate 7. The evaporation chamber 2 is equipped with a drive source (not shown in the figure) for driving the rotating rod 9 to rotate. The drive source can be one of the stepper motor, servo motor or drive motor installed on the evaporation chamber 2, and there is no restriction here.

[0035] When the oily wastewater in the evaporation chamber 2 is heated, the drive source drives the rotating rod 9 to rotate the stirring blade 10. The stirring blade 10 helps to agitate the oily wastewater and accelerates the evaporation rate of volatile oils in the wastewater.

[0036] Reference Figure 2 and Figure 4To facilitate the separation of oil and water in oily wastewater, the oil-water separation mechanism includes an oil-water separation tank 12, a partition 13, an oil-water separation membrane 14, and a pushing assembly. The oil-water separation tank 12 is fixedly installed inside the oily wastewater treatment tank 1 and is located below the evaporation tank 2. The longitudinal section of the oil-water separation tank 12 is circular, and the length direction of the oil-water separation tank 12 is parallel to the arrangement direction of the evaporation tank 2 and the gas collection tank 4. The partition 13 is fixedly installed inside the oil-water separation tank 12 and divides the oil-water separation tank 12 into a treatment chamber 15 and a water storage chamber 16. The treatment chamber 15 and the water storage chamber 16 are arranged horizontally. The treatment chamber 15 is located on the side of the oil-water separation tank 12 closer to the evaporation tank 2, and the upper end of the treatment chamber 15 is connected to the end of the output pipe 6 away from the evaporation tank 2.

[0037] Reference Figure 2 and Figure 4 An opening 17 is provided on the partition 13, located at the lower end of the partition 13. An oil-water separation membrane 14 is fixedly mounted on the partition 13 and covers the opening 17. The oil-water separation membrane 14 is a membrane structure that allows only water to pass through but not oil, which is prior art and will not be described in detail here. A pushing component is provided inside the treatment chamber 15. The pushing component is used to squeeze the water in the oily wastewater in the treatment chamber 15 into the water storage chamber 16.

[0038] Reference Figure 4 and Figure 5 To facilitate the squeezing of water from the oily wastewater in the treatment chamber 15 into the storage chamber 16, the pushing assembly includes an oily wastewater treatment plate 18 and a driving component 34. A guide rod 33 is fixed inside the treatment chamber 15. The length direction of the guide rod 33 is perpendicular to the plane of the oil-water separation membrane 14. The oily wastewater treatment plate 18 is slidably sleeved on the guide rod 33. The outer wall of the oily wastewater treatment plate 18 abuts against the inner wall of the treatment chamber 15. The sliding direction of the oily wastewater treatment plate 18 is perpendicular to the plane of the oil-water separation membrane 14. The driving component 34 is disposed on the treatment chamber 15. The driving component 34 is used to drive the oily wastewater treatment plate 18 to slide towards or away from the oil-water separation membrane 14.

[0039] After being heated, the oily wastewater enters the treatment chamber 15 through the output pipe 6, positioning the oily wastewater treatment plate 18 on the side of the output pipe 6 away from the partition 13. Then, the driving component 34 drives the oily wastewater treatment plate 18 to slide towards the oil-water separation membrane 14. The oily wastewater treatment plate 18 squeezes the oily wastewater towards the oil-water separation membrane 14, causing the water in the oily wastewater to pass through the oil-water separation membrane 14 into the water storage chamber 16, while the oil continues to be stored in the treatment chamber 15. This facilitates the separate recycling and treatment of the oil, thereby helping to protect the marine environment and avoid pollution of the sea area.

[0040] Reference Figure 4To facilitate the sliding of the oily wastewater treatment plate 18, the driving component 34 includes a lead screw 341 and a drive motor 342. The lead screw 341 rotatably passes through the treatment chamber 15, and its rotation axis is parallel to the sliding direction of the oily wastewater treatment plate 18. The oily wastewater treatment plate 18 is threaded onto the lead screw 341. The drive motor 342 is fixedly installed outside the treatment chamber 15, and the lead screw 341 is coaxially fixed with the output shaft of the drive motor 342. By starting the drive motor 342, the drive motor 342 drives the lead screw 341 to rotate, which helps the lead screw 341 drive the oily wastewater treatment plate 18 to slide as needed. In other embodiments, the lead screw 341 and the drive motor 342 can be replaced by a cylinder. The cylinder is installed outside the treatment chamber 15, and its piston rod slides through the treatment chamber 15. The oily wastewater treatment plate 18 is fixedly connected to the piston rod of the cylinder. By starting the cylinder, the oily wastewater treatment plate 18 can also be driven to slide.

[0041] Reference Figure 4 To prevent water in the storage chamber 16 from flowing back into the treatment chamber 15, a connecting pipe 35 is fixed to the side of the partition 13 near the storage chamber 16. The connecting pipe 35 is connected to the opening 17. An anti-backflow plate 36 is hinged inside the connecting pipe 35. The hinge axis of the anti-backflow plate 36 is perpendicular to the length direction of the connecting pipe 35. A reset torsion spring (not shown in the figure) is sleeved on the hinge axis of the anti-backflow plate 36. One end of the reset torsion spring is fixed to the inner wall of the connecting pipe 35, and the other end is fixed to the anti-backflow plate 36. When the reset torsion spring is in its natural state, the side of the anti-backflow plate 36 away from its own hinge axis abuts against the inner wall of the connecting pipe 35, and the side of the anti-backflow plate 36 away from its own hinge axis is tilted away from the opening 17.

[0042] When the oily wastewater treatment plate 18 squeezes the oily wastewater, the water in the oily wastewater can enter the connecting pipe 35 through the oil-water separation membrane 14, and push the anti-backflow plate 36 to rotate away from the opening 17 to open the connecting pipe 35. Then the wastewater enters the water storage chamber 16 through the connecting pipe 35. After the water in the oily wastewater has flowed into the water storage chamber 16, the resistance force on the anti-backflow plate 36 is reduced. Under the action of the reset torsion spring, the anti-backflow plate 36 rotates towards the opening 17 to close the connecting pipe 35, so that the water in the water storage chamber 16 will not flow back into the treatment chamber 15.

[0043] Reference Figure 1 and Figure 2 To facilitate the treatment of the separated oil and water, the bottom of the treatment chamber 15 is connected to a first discharge pipe 37, and the bottom of the water storage chamber 16 is connected to a second discharge pipe 38. Control valves 39 are installed on both the first discharge pipe 37 and the second discharge pipe 38. Both the first discharge pipe 37 and the second discharge pipe 38 pass through the oil and wastewater treatment tank 1 and the vehicle body 30, so as to facilitate the separate recycling and treatment of oil and water.

[0044] Reference Figure 4 and Figure 5 The oily wastewater treatment plate 18 has a through hole 19 located at its center. A cleaning frame 20 is fixedly installed inside the through hole 19. The cleaning frame 20 includes a filter frame 201 and a magnetic strip 202. The filter frame 201 is fixed inside the through hole 19, and the magnetic strip 202 is fixed inside the filter frame 201. An installation strip 21 is slidably installed on the side of the oily wastewater treatment plate 18 near the oil-water separation membrane 14. The installation strip 21 and the oily wastewater treatment plate 18 are slidably engaged by a slide rail. The sliding direction of the installation strip 21 is perpendicular to the sliding direction of the oily wastewater treatment plate 18. Specifically, the installation strip 21 is located above the through hole 19, and the sliding direction of the installation strip 21 is vertical. The sliding between the installation strip 21 and the oily wastewater treatment plate 18 is guided by a slider and a slide groove. The oily wastewater treatment plate 18 is provided with an adjusting member for adjusting the sliding direction of the installation strip 21 towards or away from the filter frame 201.

[0045] Reference Figure 4 and Figure 6 A rotating shaft 27 is rotatably mounted on the mounting strip 21. The axis of rotation of the rotating shaft 27 is perpendicular to the sliding direction of the oily wastewater treatment plate 18. Furthermore, the axis of rotation of the rotating shaft 27 is perpendicular to the sliding direction of the mounting strip 21. A sealing plate 22 for blocking or opening the impurity removal frame 20 is fixedly sleeved on the rotating shaft 27. The sealing plate 22 is rotatably connected to the mounting strip 21 through the rotating shaft 27. An elastic element is provided on the mounting strip 21 for driving the rotating shaft 27 to rotate the sealing plate 22 toward the direction closer to the oily wastewater treatment plate 18.

[0046] Reference Figure 4 and Figure 5To facilitate the adjustment of the mounting strip 21 in the direction of sliding towards or away from the filter frame 201, the adjusting components include a sliding rod 23, a connecting plate 24, a connecting rod 25, and a spring 26. The sliding rod 23 slides through the oil-water treatment plate 18, and the sliding direction of the sliding rod 23 is parallel to the sliding direction of the oil-water treatment plate 18. The sliding rod 23 is located below the filter frame 201. The connecting plate 24 is fixed to the end of the sliding rod 23 near the oil-water separation membrane 14, and the sliding rod 23 is away from the oil-water separation membrane 14. One end of the separation membrane 14 is fixed with an anti-detachment block 40 to prevent the sliding rod 23 from detaching from the oil-water treatment plate 18. One end of the connecting rod 25 is hinged to the connecting plate 24, and the other end is hinged to the mounting strip 21. The hinge axis of the connecting rod 25 is perpendicular to the sliding direction of the mounting strip 21. The distance from the connecting rod 25 to the oil-water treatment plate 18 increases along the mounting strip 21 towards the connecting plate 24. The connecting rod 25 is misaligned with the sealing plate 22, making it less likely to interfere with the rotation of the sealing plate 22. The spring 26 is sleeved on the sliding rod 23 and is located between the oil-water treatment plate 18 and the connecting plate 24. One end of the spring 26 is fixed to the adjusting plate 7, and the other end is fixed to the oil-water treatment plate 18. The spring 26 is used to push the adjusting plate 7 to slide towards the side closer to the oil-water separation membrane 14. When the spring 26 is in its natural state, the sealing plate 22 is aligned with the impurity removal frame 20, and the anti-detachment block 40 abuts against the oil-water treatment plate 18.

[0047] Reference Figure 4 and Figure 6 To facilitate the rotation of the sealing plate 22 toward the oil-water treatment plate 18, the elastic element includes a torsion spring 28. The torsion spring 28 is sleeved on the rotating shaft 27. One end of the torsion spring 28 is fixed to the mounting strip 21, and the other end is fixed to the sealing plate 22. When the torsion spring 28 is in its natural state, the sealing plate 22 abuts against the side of the oil-water treatment plate 18 that is close to the oil-water separation membrane 14.

[0048] Before the heated oily wastewater enters the treatment chamber 15, the driving component 34 drives the oily wastewater treatment plate 18 to be positioned on the side of the output pipe 6 near the partition 13. Then, the heated and evaporated oily wastewater enters the treatment chamber 15. Since the spring 26 and torsion spring 28 are in their natural state at this time, the sealing plate 22 blocks the filter frame 201. Then, the driving component 34 drives the oily wastewater treatment plate 18 to slide away from the partition 13. The oily wastewater treatment plate 18 squeezes the oily wastewater, causing the oily wastewater to generate a resistance force against the sealing plate 22. The oily wastewater resists the sealing plate 22 and rotates in the opposite direction away from the filter frame 201, opening the passage. As the oily wastewater treatment plate 18 continues to move, the oily wastewater is filtered through the filter frame 201 at the through hole 19. The magnetic strip 202 can attract magnetic substances in the oily wastewater. When all the oily wastewater flows to the side of the oily wastewater treatment plate 18 near the partition 13, the resistance force on the sealing plate 22 decreases. Under the action of the torsion spring 28, the sealing plate 22 rotates towards the filter frame 201, blocking the filter frame 201. Then, the driving component 34 drives the oily wastewater treatment plate 18 to slide towards the partition 13. Since the through hole 19 is closed at this time, as the oily wastewater flows through the filter frame 201, the oily wastewater is filtered through the filter frame 201. The compression of the oil-water treatment plate 18 allows water in the oil-water separation membrane 14 to enter the water storage chamber 16. As water gradually enters the water storage chamber 16, and the area between the oil-water treatment plate 18 and the partition plate 13 becomes mostly oil, the resistance to sliding of the oil-water treatment plate 18 towards the partition plate 13 increases. Then, the oil exerts a reverse force on the connecting plate 24, driving the connecting plate 24 and the sliding rod 23 to move away from the partition plate 13 relative to the oil-water treatment plate 18. This compresses the spring 26, and as the connecting plate 24 gradually approaches the oil-water treatment plate 18, it presses down on the connecting rod. 25. The end of the connecting rod 25 away from the connecting plate 24 extends away from the through hole 19. Then, the connecting rod 25 drives the mounting strip 21 to slide away from the through hole 19, causing the mounting strip 21 to drive the sealing plate 22 to gradually move away from the filter frame 201 and open the through hole 19. As the oily wastewater treatment plate 18 continues to move, the oil will again pass through the filter frame 201 and enter the side of the oily wastewater treatment plate 18 away from the partition 13, thereby achieving impurity removal and oil-water separation. This allows for the separate recovery and treatment of oil in the treatment chamber 15, which helps protect the marine environment and avoids pollution of the sea area. The cross-sectional area of ​​the connecting plate 24 and the sliding rod 23 can be set as needed to ensure that after most of the oily wastewater treatment plate 18 and the partition 13 are filled with oil, the oily wastewater treatment plate 18 continues to slide towards the partition 13. The oil will exert a reverse force on the connecting plate 24, driving the connecting plate 24 and the sliding rod 23 to move away from the partition 13 relative to the oily wastewater treatment plate 18.

[0049] Reference Figure 2To facilitate maintenance and cleaning of the evaporation chamber 2, gas collection chamber 4, treatment chamber 15, and water storage chamber 16, maintenance doors can be installed on all three.

[0050] The implementation principle of this invention is as follows: During use, the oily wastewater generated from boat cleaning is pumped into the evaporation box 2 through the input pipe 3 by an external suction pump. Since the oily wastewater is at room temperature at this time, the regulating plate 7 and the shape memory metal strip 8 are in their initial state. The regulating plate 7 closes the opening of the output pipe 6, causing the oily wastewater entering the evaporation box 2 to accumulate inside the evaporation box 2. Then, the heating pipe 32 is turned on to heat the oily wastewater in the evaporation box 2. The drive source drives the rotating rod 9 to rotate the stirring blade 10, which helps to accelerate the evaporation rate of volatile oils in the oily wastewater. As the temperature of the oily wastewater rises, the volatile oils in the oily wastewater enter the gas collection box 4 for storage through the gas delivery pipe 5 above. When the temperature of the oily wastewater in the evaporation box 2 is greater than the preset value of 50°C, the shape memory metal strip 8 gradually deforms. The shape memory metal strip 8 supports the regulating plate 7, causing the regulating plate 7 to move away from the output pipe 6, thus opening the output pipe 6.

[0051] Then, the heated oily wastewater in the evaporation chamber 2 enters the treatment chamber 15. At this time, the oily wastewater treatment plate 18 is in its initial position, which is the side of the output pipe 6 near the partition 13. At this time, the spring 26 and the torsion spring 28 are in their natural state, causing the sealing plate 22 to block the filter frame 201. Then, the drive motor 342 is started, which drives the lead screw 341 to rotate. The lead screw 341 drives the oily wastewater treatment plate 18 to slide away from the partition 13. The oily wastewater treatment plate 18 squeezes the oily wastewater, causing the oily wastewater to generate a resistance force against the sealing plate 22, pushing the sealing plate 22 to rotate away from the filter frame 201 and open the through hole 19. As the oily wastewater treatment plate 18 continues to move, the oily wastewater is filtered through the filter frame 201 at the through hole 19 and then enters the side of the oily wastewater treatment plate 18 near the partition 13.

[0052] When all the oily wastewater flows to the side of the oily wastewater treatment plate 18 near the partition 13, the resistance force on the sealing plate 22 decreases. Under the action of the torsion spring 28, the sealing plate 22 rotates towards the filter frame 201, blocking the filter frame 201. Then, the drive motor 342 drives the lead screw 341 to rotate in the opposite direction. The lead screw 341 drives the oily wastewater treatment plate 18 to slide towards the partition 13. Since the through hole 19 is closed at this time, the water in the oily wastewater is squeezed by the oily wastewater treatment plate 18. The water can pass through the oil-water separation membrane 14 into the water storage chamber 16. The water passing through the oil-water separation membrane 14 pushes the anti-backflow plate 36 to rotate away from the opening 17, opening the connecting pipe 35. Then, the water enters the water storage chamber 16 through the connecting pipe 35, but it is difficult for it to re-enter the treatment chamber 15. As more water from the oily wastewater enters the water storage chamber 16, and the area between the oily wastewater treatment plate 18 and the partition plate 13 becomes mostly oily, the resistance to sliding of the oily wastewater treatment plate 18 towards the partition plate 13 increases. As the oily wastewater treatment plate 18 continues to move, the oil body exerts a reverse force on the connecting plate 24, driving the connecting plate 24 and the sliding rod 23 to move away from the partition 13 relative to the oily wastewater treatment plate 18. This compresses the spring 26, and as the connecting plate 24 gradually approaches the oily wastewater treatment plate 18, it presses the connecting rod 25, causing the end of the connecting rod 25 away from the connecting plate 24 to extend away from the through hole 19. Then, the connecting rod 25 drives the mounting strip 21 to slide away from the through hole 19, causing the sealing plate 22 to gradually open the through hole 19. As the oily wastewater treatment plate 18 continues to move, the oil body will again enter the side of the oily wastewater treatment plate 18 away from the partition 13 through the filter frame 201, thereby achieving oil-water separation, impurity removal, and multi-stage treatment in the oily wastewater. The separation effect is good, which facilitates the separate treatment of oil, helps to protect the marine environment, and avoids pollution of the sea area. Because the volatile oil in the oily wastewater is collected and treated before oil-water separation, it helps to ensure the safety of the oily wastewater treatment process.

[0053] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
