[0002] Barges are typically moored vessels without power, used for loading and unloading cargo or providing refueling and water supply for other vessels. Therefore, they may generate a significant amount of oily wastewater, such as fuel spills, engine room sewage, and domestic wastewater. Oily wastewater and washing water, in particular, contain organic matter, suspended solids, grease, and chemicals, making them unsuitable for direct discharge. However, existing oily wastewater recovery and treatment systems have the following drawbacks during operation: Firstly, considering the potential vibration issues in the marine environment, certain requirements are placed on shock absorption and structural stability. Secondly, there is the space issue in assembling the barge deck storage, which requires the assembly of multiple modules; Thirdly, the filter structure is prone to clogging and other problems after prolonged use. Summary of the Invention

The various embodiments of this invention are described in detail below with reference to the accompanying drawings.

[0020] Example 1

[0021] Please see Figures 1 to 14The present invention preferably provides the following technical solution: a waste oil and water recycling and treatment device for a pontoon, comprising: a shock-absorbing assembly module assembled with the pontoon deck compartment, a storage tank module disposed on the shock-absorbing assembly module, and a multi-layer filter module communicating with the bottom of the storage tank module; the multi-layer filter module includes a cylinder 314, transmission components disposed at the upper and lower ends of the cylinder 314, and a first filter layer 414, a second filter layer 415, and a third filter layer 416 arranged sequentially from the inside to the outside between the transmission components; a second brush 4172 is disposed on the inner wall of the second filter layer 415, and a third brush 4171 is disposed on the inner wall of the third filter layer 416; when the transmission components are running, the second filter layer (415) The inner tangent of the second filter layer (415) rotates eccentrically along the outer wall of the first filter layer (414), and the second brush (4172) cleans the outer wall of the first filter layer (414). The outer tangent of the second filter layer (415) rotates eccentrically along the inner wall of the third filter layer (416), and the third brush (4171) cleans the outer wall of the second filter layer (415). The outer wall of the cylinder 314 is circumferentially distributed with suction modules and water-oil separation modules connected to each suction module. When the suction module is running, the sewage passes through the first filter layer 414, the second filter layer 415 and the third filter layer 416 from the inside to the outside to complete multiple filtrations and achieve water-oil separation under the action of the water-oil separation module.

[0022] This application mainly includes a shock-absorbing assembly module, a storage tank module, a multi-layer filtration module, and a water-oil separation module. The shock-absorbing assembly module can be assembled with the pontoon deck storage area; its structural characteristics can mitigate vibrations during pontoon operation to adapt to the rough seas. The inlet and outlet of the storage tank module are connected to the pontoon's sewage pipe and the multi-layer filtration module, respectively, to achieve sewage collection and subsequent filtration and cleaning. (See reference...) Figure 14 Simultaneously, the water-oil separation module, connected to the output of the multi-layer filtration module, further receives the filtered wastewater and performs water-oil separation treatment. (See [link to relevant documentation]). Figure 1 , 2 As shown; Considering the complex composition of oily wastewater, which may contain impurities and particulate matter, this application sets up a filtration device in the pretreatment stage of wastewater, followed by oil-water separation, following the principle of classified treatment. The multi-layer filtering module set up in this invention is specifically combined with Figure 3 , 6 As shown in Figures 7, 8, and 9, the transmission ring assembly and transmission frame assembly respectively provided at the upper and lower ends of the cylinder 314 are connected sequentially from the inside out by a first filter layer 414, a second filter layer 415, and a third filter layer 416. The second filter layer 415 is eccentrically positioned relative to the first filter layer 414 and the third filter layer 416. Furthermore, the second brush 4172 and the third brush 4171 on the inner walls of the second filter layer 415 and the third filter layer 416 are combined with… Figure 7 , 8As shown in Figures 9 and 1, when the inner tangent of the second filter layer 415 rotates eccentrically along the outer wall of the first filter layer 414, the second brush 4172 on the inner wall of the second filter layer 415 can clean the outer wall of the first filter layer 414. At the same time, when the outer tangent of the second filter layer 415 rotates eccentrically along the inner wall of the third filter layer 416, the second brush 4172 on the inner wall of the third filter layer 416 can clean the outer wall of the second filter layer 415, thus completing the filtration and self-cleaning process. The self-cleaning process can remove dirt deposits on the surface of the filter structure, extend the cleaning cycle, and reduce the occurrence of clogging that affects the filtration effect of the first filter layer 414, the second filter layer 415, and the third filter layer 416. Meanwhile, the suction modules distributed around the outer periphery of the cylinder 314 can transfer sewage from the storage tank module to the multi-layer filtration module and pass through the first filtration layer 414, the second filtration layer 415 and the third filtration layer 416 from the inside out, completing multiple filtrations and discharging the filtered water to the water-oil separation module. At this time, the water-oil separation module can use the cavitation effect of ultrasound to break up oil droplets, reducing the difficulty of separation, and promote the micro-mixing and separation of the oil-water mixture by relying on the acoustic flow effect, thus strengthening the separation process. This invention integrates shock absorption, storage tank, multi-stage filtration, and oil-water separation functions through the effective cooperation of various modules. The multi-stage filtration also has a self-cleaning function, which removes dirt deposits on the surface of the filter structure and extends the cleaning cycle, while the shock absorption design can adapt to the turbulence at sea and improve the practicality of the device.

[0023] Further, the transmission assembly includes a transmission ring assembly and a transmission frame assembly at the upper and lower ends. The transmission ring assembly includes a first ring body 411, a second ring body 412, and a third ring body 413, which are sequentially fixed from the inside out. The second ring body 412 is eccentrically disposed relative to the first ring body 411 and the third ring body 413, and a through groove 422 is formed on the first ring body 411. The transmission frame assembly includes a first frame body 423, a second frame body 424, and a third frame body 425, which correspond one-to-one with and are disposed opposite to the first ring body 411, the second ring body 412, and the third ring body 413. 25; and a plate 421 fixed between the first filter layer 414 and the third filter layer 416, wherein the first filter layer 415 is limited at both ends on both sides of the plate 421, wherein the first filter layer 414 is rotatably installed with the first ring body 411 and the first frame body 423, the second filter layer 415 is sleeved between the second ring body 412 and the second frame body 424 and is eccentrically set with the first filter layer 414 and the third filter layer 416, and the third filter layer 416 is rotatably installed with the third ring body 413 and the third frame body 425 and is fixed with the first filter layer 414 and the cylinder body 314.

[0024] The transmission ring assembly here is combined Figure 6The first ring body 411, the second ring body 412, and the third ring body 413, in which they are located, are sequentially fixed from the inside out. The second ring body 412 is eccentrically positioned relative to the first ring body 411 and the third ring body 413. (See the transmission frame assembly for details.) Figure 5 The first frame 423, the second frame 424, and the third frame 425 correspond one-to-one with the first ring 411, the second ring 412, and the third ring 413 and are arranged relative to each other. In combination with... Figure 3 , 5 6. The first filter layer 414 is rotatably mounted with the first ring body 411 and the third ring body 413. The second filter layer 415 is sleeved between the second ring body 412 and the second frame body 424 and is eccentrically positioned with respect to the first filter layer 414 and the third filter layer 416. The third filter layer 416 is rotatably mounted with the third ring body 413 and the third frame body 425 and is fixed with respect to the first filter layer 414. Therefore, when the transmission ring assembly and the transmission frame assembly rotate, the second ring body 412 and the second frame body 424 can push the second filter layer 415 to rotate eccentrically between the first filter layer 414 and the third filter layer 416, while the first filter layer 414 and the third filter layer 416 remain stationary. This achieves the process of the inner tangent surface of the second filter layer 415 rotating eccentrically along the outer wall of the first filter layer 414, and the outer tangent surface of the second filter layer 415 rotating eccentrically along the inner wall of the third filter layer 416.

[0025] Furthermore, a connecting pipe for communication between the transmission ring assembly and the storage tank module is also installed; the connecting pipe includes a docking chamber 313 fixed to the top of the cylinder 314 and communicating with the upper edge of the through groove 422, and a pipe body 312 annularly communicating with the docking chamber 313, and a transfer chamber 311 is inserted and communicated at one end of several pipe bodies 312 away from the docking chamber 313, and the transfer chamber 311 is communicating with the storage tank module.

[0026] Combination Figure 3 The transmission ring assembly is located at the upper end of the cylinder 314, and the first ring body 411 where the transmission ring assembly is located has a through groove 422. The through groove 422 is connected to the storage tank module through the docking chamber 313, the pipe body 312, and the transfer chamber 311 to realize the sewage transfer process. Since the pipe body 312 and the transfer chamber 311 are detachably plugged in, and a sealing ring is provided at the connection between the two, it is convenient for cleaning the inside of the device and replacing parts. Furthermore, a drive motor 418 is provided on the top of the docking compartment 313, and a connecting rod 419 is fixed to the output end of the drive motor 418. The bottom end of the connecting rod 419 passes through the through holes opened on the docking compartment 313 and the first ring body 411 in sequence and is fixedly connected to the first ring body 411 and the first frame body 423, serving as a drive source for the synchronous rotation of the transmission ring assembly and the transmission frame assembly.

[0027] As the driving structure for the transmission ring assembly and the transmission frame assembly, the bottom end of the connecting rod 419 fixed on the drive motor 418 passes through the docking chamber 313 and the through hole opened on the first ring body 411 in sequence, and is fixedly connected to the first ring body 411 where the transmission ring assembly is located and the first frame body 423 where the transmission frame assembly is located, thereby realizing the synchronous driving process of the transmission ring assembly and the transmission frame assembly, and thus realizing the eccentric rotation of the second filter layer 415 inside the first filter layer 414 and the third filter layer 416.

[0028] Example 2

[0029] In another embodiment of the present invention, a scraper assembly is also provided in the middle of the first filter layer 414 for cleaning the inner wall of the first filter layer 414; the scraper assembly includes a scraper body 420 that is annularly fixed on the connecting rod 419 and fits against the inner wall of the first filter layer 414.

[0030] Combination Figure 8 , 9 As shown, the connecting rod 419 is fixed to the scraper body 420 and rotates through the power provided by the drive motor 418, while the second filter layer 415 is fixed to the third filter layer 416 and the cylinder 314 through the plate 421, thereby realizing the cleaning process of the scraper body 420 on the inner wall of the second filter layer 415. Since the first filter layer 414 is the first to come into contact with sewage, it is most prone to clogging. Therefore, this embodiment, in conjunction with Embodiment 1, can achieve a self-cleaning process on both the inner and outer sides of the first filter layer 414, ensuring the filtration effect of the first filter layer 414.

[0031] Example 3

[0032] In another embodiment of the present invention, each suction module includes two sets of relatively distributed transmission disc assemblies. Each transmission disc assembly includes a first disc body 614, a second disc body 615, and a third disc body 616 fixed from the inside out; and a first transmission ring 617 and a third transmission ring 611 respectively rotatably installed between the two first disc bodies 614 and between the two third disc bodies 616, with a connecting plate 618 fixed at the center of the bottom surface of the first transmission ring 617 and the third transmission ring 611; it also includes a second transmission ring 619 sleeved between the two second disc bodies 615, with the two ends of the second transmission ring 619 limited and installed on both sides of the connecting plate 618 and eccentrically distributed with the first disc bodies 614 and the third disc bodies 616; the bottom surfaces of the third transmission ring 611 are also provided with an inlet 612 and an outlet 613, with the inlet 612 detachably installed with the cylinder 314; and a motor disposed in one of the transmission disc assemblies and fixed to the first disc body 614 for synchronous rotation of the first disc body 614, the second disc body 615, and the third disc body 616.

[0033] Combination Figure 3 , 10As shown, the first transmission ring 617, the second transmission ring 619, and the third transmission ring 611 are distributed internally and externally. The first transmission ring 617 and the third transmission ring 611 are fixed, while the second transmission ring 619 rotates eccentrically under the action of the two third discs 616. Since the third transmission ring 611 has an inlet 612 and an outlet 613 at both ends, with the inlet 612 connected to the cylinder 314 and the outlet 613 connected to the water-oil separation module, when the second transmission ring 619... Figure 10 When rotated clockwise, the space near the inlet 612 of the third drive ring 611 gradually increases, drawing water from inside the cylinder 314 into that space. At the same time, the area near the outlet 613 of the third drive ring 611 decreases, squeezing the water in the third drive ring 611 toward the outlet 613, thus realizing the sewage discharge process.

[0034] Furthermore, the top of the third drive ring 611 is also provided with a placement box 620 and a mounting groove opened on the top of the third drive ring 611, and a transparent layer 621 connected to the placement box 620 is provided in the mounting groove.

[0035] As can be seen from the above, such as Figure 10 The sewage inside the third drive ring 611 and the second drive ring 619 can be drawn in from the left and discharged to the right. During this process, when the sewage moves clockwise between the third drive ring 611 and the second drive ring 619, the third drive ring 611 can squeeze the sewage towards the permeable layer 621 when the sewage passes the upper part of the third drive ring 611. At this time, the sewage enters the placement box 620 through the permeable layer 621. The liquid inside the placement box 620, preferably a disinfectant or sewage treatment agent, comes into contact with the sewage and mixes with it for treatment. It is worth noting that the placement box 620 here is a placement chamber with a self-sealing cover.

[0036] Furthermore, an installation assembly is provided between the inlet 612 and the cylinder 314. The installation assembly includes an assembly 711 that is fixed and communicates with the lower part of the cylinder 314. The end of the assembly 711 is provided with an assembly block 712 and a connecting block fixed at the inlet 612. It also includes a bolt 713 provided between the assembly block 712 and the connecting block for connecting the two. A sealing gasket is also provided between the assembly block 712 and the connecting block.

[0037] Example 4

[0038] In another embodiment of the present invention, the shock-absorbing assembly module includes an elastic bladder 811; the storage tank module includes a platform 111 fixed to the top of the elastic bladder 811, a first connecting plate 211 annularly fixed to the top of the platform 111, a telescopic sleeve 212 fixed on each first connecting plate 211, and a telescopic rod 213 telescopically installed inside the telescopic sleeve 212, with a second connecting plate 216 fixed to the upper part of the telescopic rod 213 and an installation ring 214 fixed to the middle part, and a spring 215 connecting the installation ring 214 and the telescopic sleeve 212 to the outer wall of the telescopic rod 213; it also includes a folding storage bladder 217 fixed to several second connecting plates 216 for storing sewage; further, a connector 101 is provided on the top of the folding storage bladder 217.

[0039] Combination Figure 1 As shown, in this embodiment, the first connecting plate 211, the second connecting plate 216, and the telescopic structure between them are preferably four in total. The platform 111, which is fixed to the first connecting plate 211, is fixed to the elastic bladder 811. The folding storage bladder 217, which is fixed to the second connecting plate 216, is connected to the connecting pipe. At the same time, the connector 101 at the top of the folding storage bladder 217 can be connected to the barge's sewage pipe. Figure 14 Therefore, when the elastic bladder 811 is rocked by the ship, the telescopic structure can adapt to the up and down movement, and the folding storage bladder 217 expands and contracts with the amount of liquid stored, thus completing the storage of sewage.

[0040] Example 5

[0043] Example 6

[0044] In another embodiment of the present invention, the water-oil separation module corresponds one-to-one with the suction module. Each water-oil separation module includes a plurality of ultrasonic transducers 913 disposed on the side wall of the elastic bladder 811; and a connecting frame 911 disposed on the outlet 613 of the corresponding suction module. Each connecting frame 911 is detachably connected to a valve body 912. It also includes a valve groove 914 disposed inside the valve body 912 and connected to the outside. Both sides of the valve groove 914 are provided with staggered grooves 916. Each groove 916 area is fixed with a baffle 915. When the oily wastewater flows from top to bottom, under the action of the baffle 915, the oily wastewater is divided into the main stream in the valve groove 914 and the tributary in the groove 916. Under the action of the groove 916, the tributary reverses its direction and opposes the main stream, forming a vortex and slowing down the flow rate of the oily wastewater.

[0045] In this embodiment, combined with Figure 1 , 11 As shown in Figures 12 and 13, the ultrasonic transducer 913 is a piezoelectric transducer that uses the piezoelectric effect of piezoelectric crystals to convert energy. It is a mature technology. When the ultrasonic waves emitted by the transducer propagate in oily wastewater, they will generate cavitation effect and acoustic flow effect, so as to realize the separation of oily wastewater flowing into the valve body 912 through the connecting frame 911 and the process of breaking up oil droplets. The principle of cavitation effect in oily wastewater is as follows: when the ultrasonic intensity exceeds the threshold, tiny bubbles (cavitation nuclei) are generated in the oily wastewater. Subsequently, they collapse rapidly due to pressure changes, generating local high temperature and high pressure, forming a high-speed jet that impacts the surrounding oil droplets or pollutants, breaking them into smaller particles. It can also directly destroy the interfacial film of emulsified oil droplets (such as proteins and surfactants), reduce the oil-water interfacial tension, and degrade large molecular organic matter, reducing the resistance of subsequent cyclone separation. The principle of acoustic flow effect in oily wastewater is as follows: ultrasound induces stable flow (standing wave mode) in oily wastewater along the direction of sound wave propagation, enhancing turbulence and promoting microscopic mixing and separation of the oil-water mixture. To improve the treatment effect of oily wastewater, the valve groove 914 inside the valve body 912 and the baffle 915 inside the valve groove 914 can realize the eddy current deceleration process, specifically combined with... Figure 11 , 12 As shown in Figure 13, when oily wastewater flows from top to bottom from valve body 912, under the action of baffle 915, the oily wastewater is divided into the main stream in valve groove 914 and the tributary in groove 916. The tributary reverses its direction under the action of groove 916 and opposes the main stream, similar to two opposing water columns, thereby forming a vortex and slowing down the flow of oily wastewater, thus prolonging the interaction time between oily wastewater and ultrasonic transducer 913 and ensuring the oil removal effect.
