Description

Technical Field

[0001] The invention belongs to the technical field of sewage treatment equipment, in particular to an oily sewage treatment equipment. Background Art

[0002] Oily wastewater treatment equipment is specially designed to remove oil pollutants from water and is widely used in petrochemical, machinery manufacturing, food processing and other industries. These equipment usually use a combination of physical, chemical and biological treatment technologies to effectively remove or reduce oil, heavy metals and other harmful substances in wastewater to a safe level.

[0003] When discharging oily wastewater, since the oily wastewater contains oil and other substances, the oil can be recycled again after being collected. When treating the oily wastewater, a sponge is usually used to absorb the oil. This method can no longer continue to absorb oil when the sponge absorbs a certain amount of oil and needs to be replaced in time to ensure the normal use of the oil removal operation. This is time-consuming and labor-intensive, and is not conducive to the operation.

[0004] To this end, the present invention provides an oily wastewater treatment device. Summary of the invention

[0005] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0006] The technical solution adopted by the present invention to solve its technical problem is as follows: the oily wastewater treatment equipment described in the present invention comprises a base, a casing is fixedly installed on the top of the base, a plurality of cylinders are fixedly installed on the inner wall of the casing, a water flow pipe is fixedly installed on the outer walls of the plurality of cylinders, a water diversion valve is fixedly installed on the top of the casing, one end of the plurality of water flow pipes is fixedly installed on the bottom of the water diversion valve, a water inlet pipe is fixedly installed on the top of the water diversion valve, an oil collecting assembly is arranged on the top of the inner wall of the cylinder, the oil collecting assembly comprises an oil absorption plate, one side of the oil absorption plate placed in the cylinder is an oleophilic sponge ring plate, and the oleophilic sponge ring plate at the bottom of the oil absorption plate collects and absorbs the oil in the oily wastewater entering the cylinder; By passing the oily sewage from the water inlet pipe into the water diverter valve, the water diverter valve divides the oily sewage into four streams and passes them into the cylinder through the water flow pipe. Since the density of oil is smaller than that of water, when the oily sewage is passed into the cylinder, the oil in the oily sewage will float upwards. By continuously passing the oily sewage into the cylinder through the water diverter valve, the oily sewage in the cylinder will fill the entire cylinder, and the oil will float on the top of the cylinder. At this time, the oleophilic sponge ring plate on one side of the oil absorption plate in the oil collecting assembly absorbs the oil floating on the top of the cylinder. By continuously passing the oily sewage into the cylinder through the water inlet pipe, the oleophilic sponge ring plate on one side of the oil absorption plate continuously absorbs the oil, thereby achieving the effect of concentrated oil absorption. The collected oil can be recycled through subsequent treatment, thereby achieving the effect of treating the oil in the oily sewage.

[0007] Preferably, a clean dirt box is fixedly installed at the bottom of the base, and a dirt removal mechanism is arranged inside the clean dirt box. The dirt removal mechanism is used to remove remaining substances in the oily wastewater. The bottoms of the multiple cylinders are connected to the top of the clean dirt box, and a water outlet pipe is fixedly installed on the outer wall of the clean dirt box. When the oleophilic sponge ring plate on one side of the oil absorption plate continues to absorb the oil, the sewage in the oily wastewater will be retained in the clean dirt box through the bottom of the cylinder. The dirt removal mechanism in the clean dirt box removes remaining substances in the oily wastewater, so that the oily wastewater meets the discharge standard and avoids affecting the ecological environment. The water after decontamination can be discharged by connecting a flow mechanism externally at the water outlet pipe.

[0008] Preferably, the oil collecting assembly also includes a rotating rod, which passes through the interior of the oil absorption plate and is fixedly connected to the oil absorption plate, the two ends of the rotating rod are respectively placed on the outside of the cylinder, and the oil absorption plate is rotatably connected to the inner wall of the cylinder through the rotating rod, and a rotating wheel is fixedly installed at both ends of the rotating rod. When the oil flows to the top of the cylinder through the density ratio, the oleophilic sponge ring plate on one side of the oil absorption plate absorbs the oil. When the oil absorption amount of the oil absorption plate reaches a certain level, the water diversion valve is stopped from passing oily sewage into the cylinder, and the rotating wheel is driven to rotate. When the rotating wheel rotates, the oil absorption plate is driven to flip in the cylinder through the rotating rod, and the oleophilic sponge ring plate on one side of the oil absorption plate rotates at the top of the cylinder so that the oleophilic sponge ring plate on one side of the oil absorption plate faces upward, so that the oil absorbed in the oleophilic sponge ring plate on one side of the oil absorption plate can be removed, thereby facilitating the oil removal.

[0009] Preferably, a motor is fixedly installed on the top of the casing, the motor is placed inside the water diverter valve, a screw is fixedly installed on the output end of the motor, the outer wall of the screw is threadedly connected with a slider, and the outer wall of the slider is fixedly installed with an oil pressing plate, the oil pressing plate corresponds to the center position of the cylinder body and the oil absorption plate, and the oil-affecting sponge ring plate is squeezed and oil is extracted by the oil pressing plate, which can save the step of frequently replacing the oil-affecting sponge ring plate, and is more conducive to operation. When the oil absorption amount of the oil absorption plate reaches a certain level, the motor drives the screw to rotate, and the slider will move downward from the top of the screw. During the movement, the slider drives the oil pressing plate to move downward. Since the oil pressing plate corresponds to the center position of the cylinder body and the oil absorption plate, when the slider drives the oil pressing plate to move to a certain position, the oil pressing plate squeezes the oil-affecting sponge ring plate on one side of the oil absorption plate, and the oil absorbed in the oil-affecting sponge ring plate on one side of the oil absorption plate will be pressed out of the oil-affecting sponge ring plate to extract oil. The oil pressing plate squeezes the oil-affecting sponge ring plate to extract oil, which can save the step of frequently replacing the oil-affecting sponge ring plate, and is more conducive to operation.

[0010] Preferably, gear rods are symmetrically fixedly installed on the outer wall of the oil pressure plate, and the teeth on the two gear rods are respectively engaged with the teeth on the two rotating wheels. When the slider drives the oil pressure plate to move downward, the oil pressure plate drives the gear rods downward, and the gear rods will push the rotating wheel to rotate through the engagement of the teeth, thereby turning the oil absorption plate over, thereby flipping the oil absorption plate.

[0011] The camming wheel is a key element in the embodiment of the present invention and is a key element in the process of movement of the camming wheel.

[0012] Preferably, an oil ring is fixedly installed on the top of each of the multiple cylinders, the oil suction plate is rotatably connected to the inner wall of the oil ring, a lubricating oil port is opened in the middle position of the inner wall of the oil ring, the lubricating oil port is an oblique sliding port, a ladder ring port is opened on the inner wall of the oil ring, the ladder ring port is an oil placing area, and multiple oil pressure plates are slidingly connected to the inner walls of the multiple oil rings respectively. When the oil pressure plate squeezes the oil-philic sponge ring plate on one side of the runner, the oil pressure plate squeezes the oil in the oil-philic sponge ring plate to flow around, and the squeezed oil flows into the ladder ring port in the oil ring through the lubricating oil port in the middle of the oil ring for storage, which is convenient for the subsequent collection of the squeezed oil.

[0013] Preferably, an oil storage tank is fixedly installed between the outer walls of the multiple cylinders, and an oil flow pipe is arranged between the oil storage tank and the multiple oil rings. When the oil enters the ladder ring opening, the oil in the ladder ring opening finally flows into the oil storage tank through the oil flow pipe for storage, thereby playing the role of centralized oil storage.

[0014] Preferably, water passing plates are fixedly installed on the inner walls of the multiple cylinders, and round blocks are fixedly installed at the middle positions of the bottoms of the multiple water passing plates. When the oleophilic sponge ring plate on one side of the oil absorption plate performs oil absorption operation, the sewage flows downward from the cylinder, finally flows out of the cylinder through the water passing plate and is placed in the clean sewage tank for sewage removal operation. By setting multiple water flow apertures on the water passing plate, the flow speed of the sewage placed in the cylinder is less than the introduction speed of the oily sewage into the cylinder when the sewage flows downward, so that the oily sewage can fill the entire cylinder when it is introduced, and the oil in the oily sewage can be placed on the top of the cylinder and absorbed by the oleophilic sponge ring plate on one side of the oil absorption plate, thereby playing a role in flow control.

[0015] Preferably, the inner walls of the multiple cylinders are fixedly installed with rotating shafts, the outer walls of the multiple rotating shafts are symmetrically hinged with water blocking plates, the outer walls of the multiple round blocks are symmetrically fixedly installed with return springs, one end of the multiple return springs is respectively fixed to the bottom of the multiple water blocking plates, and when the amount of oily sewage passed into the cylinder accumulates more and more, when the amount of oily sewage accumulates to a certain mass, the sewage will push the water blocking plate through gravity to squeeze the return spring and rotate it open from the rotating shaft, and the sewage flowing downward through the water pass plate will flow downward from the opening of the water blocking plate into the clean water In the sewage tank, when the oil absorption plate turns over to squeeze out the oil, the water diverter valve stops passing the oily sewage into the cylinder. The sewage in the cylinder will continue to push the water blocking plate to open and continue to flow downward due to its weight. When the oily sewage in the cylinder flows downward to a certain mass, the mass of the oily sewage will decrease. Through the elastic force of the reset spring, the water blocking plate will reset to block the flow of the oily sewage remaining in the cylinder, preventing the oily sewage from flowing out of the cylinder with the oil when the oil absorption plate turns over to squeeze out the oil, thereby blocking the oil.

[0016] The beneficial effects of the present invention are as follows: 1. The oily wastewater treatment equipment described in the present invention, when the oil flows to the top of the cylinder through the density ratio of the oil body to water, the oleophilic sponge ring plate on one side of the oil absorption plate absorbs the oil. When the oil absorption amount of the oil absorption plate reaches a certain level, the water diversion valve is stopped from passing the oily wastewater into the cylinder, and the rotating wheel is driven to rotate. When the rotating wheel rotates, the oil absorption plate is driven to flip in the cylinder through the rotating rod. The oleophilic sponge ring plate on one side of the oil absorption plate rotates at the top of the cylinder, so that the oleophilic sponge ring plate on one side of the oil absorption plate faces upward, and the oil absorbed in the oleophilic sponge ring plate on one side of the oil absorption plate will be removed, thereby achieving the effect of facilitating oil removal.

[0017] 2. The oil-containing wastewater treatment equipment described in the present invention is that when the oil absorption amount of the oil absorption plate reaches a certain level, the motor drives the oil pressure plate to move downward. When the slider drives the oil pressure plate to move to a certain position, the oil pressure plate squeezes the oleophilic sponge ring plate on one side of the oil absorption plate. The oil absorbed in the oleophilic sponge ring plate on one side of the oil absorption plate will be pressed and flow out from the oleophilic sponge ring plate to extract the oil. Squeezing the oleophilic sponge ring plate by the oil pressure plate to extract the oil can save the step of frequently replacing the oleophilic sponge ring plate, which is more conducive to operation.

[0018] 3. The oily wastewater treatment equipment described in the present invention, when the wheel is driven to rotate by the gear rod, the wheel squeezes the tooth block to move and rotate, and through the tooth ratio, when the oil suction plate is completed, the teeth on the gear rod will no longer mesh with the teeth on the wheel. At this time, the wheel will no longer rotate, and the tooth block will slide out of the torque box through the elastic force of the push block spring, and the tooth block will be stuck between the two teeth of the wheel for limit fixing, to prevent the wheel from shaking due to the loss of the limiting force of the gear rod when the oil pressure plate is pressed down, thereby affecting the extrusion effect of the oil pressure plate, and playing the role of limiting and fixing the oil suction plate.

[0019] 4. The oily wastewater treatment equipment described in the present invention stops the water diversion valve from passing the oily wastewater into the cylinder when the oil absorption plate is turned over to squeeze the oil. When the oily wastewater in the cylinder flows downward to a certain mass, the mass of the oily wastewater decreases. The water blocking plate will reset through the elastic force of the reset spring to block the flow of the oily wastewater remaining in the cylinder, preventing the oily wastewater from flowing out of the cylinder with the oil when the oil absorption plate is turned over to squeeze the oil, thereby playing the role of blocking the oil.

[0020] 5. The oily wastewater treatment equipment described in the present invention, when the lipophilic sponge ring plate on one side of the oil absorption plate performs oil absorption operation, the wastewater flows downward from the cylinder body, passes through the water pass plate and finally flows into the clean sewage tank for decontamination operation. By setting multiple water flow apertures on the water pass plate, the flow speed of the wastewater placed in the cylinder body is lower than the introduction speed of the oily wastewater into the cylinder body when the wastewater flows downward, so that the oily wastewater can fill the entire cylinder body when it is introduced, and the oil in the oily wastewater can be placed on the top of the cylinder body and absorbed by the lipophilic sponge ring plate on one side of the oil absorption plate, thereby playing a role in controlling the flow volume.

DETAILED DESCRIPTION

[0024] 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.

[0025] like Figures 1 to 7 As shown, an oily wastewater treatment device according to an embodiment of the present invention comprises a base 2, a casing 1 is fixedly installed on the top of the base 2, a plurality of cylinders 8 are fixedly installed on the inner wall of the casing 1, a water flow pipe 5 is fixedly installed on the outer walls of the plurality of cylinders 8, a water diversion valve 3 is fixedly installed on the top of the casing 1, one end of the plurality of water flow pipes 5 is fixedly installed on the bottom of the water diversion valve 3, a water inlet pipe 4 is fixedly installed on the top of the water diversion valve 3, an oil collecting assembly is arranged on the top of the inner wall of the cylinder 8, and the oil collecting assembly comprises an oil absorption plate 19, one side of the oil absorption plate 19 placed in the cylinder 8 is an oleophilic sponge ring plate, and the oleophilic sponge ring plate at the bottom of the oil absorption plate 19 collects and absorbs the oil in the oily wastewater entering the cylinder 8; When treating and discharging oily wastewater, the oil in the oily wastewater is mostly oil containing petroleum substances, which can be recycled again after being collected; By passing the oily sewage from the water inlet pipe 4 into the water diverter valve 3, the water diverter valve 3 divides the oily sewage into four streams and passes them into the cylinder 8 through the water flow pipe 5, so as to increase the sewage treatment efficiency. Since the device is suitable for operation under the condition that the density of oil is smaller than that of water, when the oily sewage is passed into the cylinder 8, the oil in the oily sewage will float upwards, and the oily sewage will continue to be passed into the cylinder 8 through the water diverter valve 3, so that the oily sewage will fill the entire cylinder 8, and the oil will float on the top of the cylinder 8. At this time, the oleophilic sponge ring plate on one side of the oil absorption plate 19 in the oil collecting assembly absorbs the oil floating on the top of the cylinder 8, and the sewage is discharged. Water with a density lower than that of urine will flow downward, and oily sewage will be continuously introduced into the cylinder 8 through the water inlet pipe 4. The oleophilic sponge ring plate on one side of the oil absorption plate 19 will continuously absorb the oil to achieve the effect of concentrated oil absorption. The collected oil can be recycled through subsequent treatment, thereby achieving the effect of treating the oil in the oily sewage. It should be noted here that the size of the oleophilic sponge ring plate on one side of the oil absorption plate 19 is smaller than that of the oil absorption plate 19, a sealing ring is provided at the outer ring of the oil absorption plate 19, an oil-proof coating is applied inside the cylinder 8, and the oleophilic sponge ring plate is composed of an oleophilic and hydrophobic sponge.

[0026] like Figure 1 to Figure 2 As shown, a clean dirt box 6 is fixedly installed at the bottom of the base 2, and a dirt removal mechanism is arranged inside the clean dirt box 6. The dirt removal mechanism is used to remove the remaining substances in the oily wastewater. The bottoms of the multiple cylinders 8 are connected to the top of the clean dirt box 6, and a water outlet 7 is fixedly installed on the outer wall of the clean dirt box 6; When the oleophilic sponge ring plate on one side of the oil absorption plate 19 continues to absorb the oil, the sewage in the oily sewage will flow into the clean sewage tank 6 through the bottom of the cylinder 8. The decontamination mechanism in the clean sewage tank 6 removes the remaining substances in the oily sewage, so that the oily sewage reaches the discharge standard and avoids affecting the ecological environment. By connecting a flow mechanism to the outlet pipe 7, the water after decontamination can be discharged.

[0027] like Figure 5 to Figure 6 As shown, the oil collecting assembly further includes a rotating rod 20, which penetrates the interior of the oil absorbing plate 19 and is fixedly connected to the oil absorbing plate 19, and the two ends of the rotating rod 20 are respectively placed outside the cylinder 8 and the oil absorbing plate 19 is rotatably connected to the inner wall of the cylinder 8 through the rotating rod 20, and the two ends of the rotating rod 20 are fixedly mounted with a rotating wheel 16; When the oil flows to the top of the cylinder 8 through the density ratio with water, the oleophilic sponge ring plate on one side of the oil absorption plate 19 absorbs the oil. When the flow rate of the sewage introduced reaches a certain level, the water diverter valve 3 stops introducing the oily sewage into the cylinder 8, and drives the impeller 16 to rotate. When the impeller 16 rotates, the oil absorption plate 19 is turned over in the cylinder 8 through the rotating rod 20. The oleophilic sponge ring plate on one side of the oil absorption plate 19 rotates 180 degrees at the top of the cylinder 8, so that the oleophilic sponge ring plate on one side of the oil absorption plate 19 faces upward, and the oil absorbed in the oleophilic sponge ring plate on one side of the oil absorption plate 19 will be removed subsequently, thereby achieving the effect of removing oil. It should be noted here that a flow cut-off device is arranged inside the water flow pipe 5. The flow cut-off device is used to start when a certain amount of sewage is introduced into the cylinder 8, and the sewage introduced into the water inlet flow pipe 5 is blocked and closed.

[0028] like Figure 3 to Figure 4 As shown, a motor 9 is fixedly installed on the top of the casing 1, and the motor 9 is placed inside the water diverter valve 3. A screw 10 is fixedly installed on the output end of the motor 9. A slider 13 is threadedly connected to the outer wall of the screw 10. An oil pressing plate 14 is fixedly installed on the outer wall of the slider 13. The oil pressing plate 14 corresponds to the center position of the cylinder 8 and the oil absorbing plate 19. The oil pressing plate 14 is used to squeeze the oleophilic sponge ring plate to extract oil, which can save the step of frequently replacing the oleophilic sponge ring plate and is more conducive to operation. When the oil absorption amount of the oil absorption plate 19 reaches a certain level, the motor 9 drives the screw 10 to rotate, and the slider 13 will move downward from the top of the screw 10. During the movement, the slider 13 drives the oil pressure plate 14 to move downward. Since the oil pressure plate 14 corresponds to the center position of the cylinder 8 and the oil absorption plate 19, when the slider 13 drives the oil pressure plate 14 to move to a certain position, the oil pressure plate 14 squeezes the oleophilic sponge ring plate on one side of the oil absorption plate 19, and the oil absorbed in the oleophilic sponge ring plate on one side of the oil absorption plate 19 will be pressed out of the oleophilic sponge ring plate to extract the oil.

[0029] like Figures 3 to 6 As shown, the outer wall of the oil pressure plate 14 is symmetrically fixed with gear rods 15, and the teeth on the two gear rods 15 are respectively meshed with the teeth on the two rotating wheels 16; When the slider 13 drives the oil pressure plate 14 to move downward, the oil pressure plate 14 drives the gear rod 15 to move downward, and the gear rod 15 drives the rotating wheel 16 to rotate through the tooth meshing, so that the oil absorption plate 19 is turned over, thereby playing the role of flipping the oil absorption plate 19.

[0030] like Figure 5 to Figure 6As shown, a rectangular box 21 is symmetrically fixedly installed on the outer wall of the cylinder 8, and a plurality of shafts 26 are fixedly installed on the inner wall of the rectangular box 21. One end of the plurality of shafts 26 is slidably connected with a tooth block 24. A plurality of push block springs 25 are arranged between the tooth block 24 and the inner wall of the rectangular box 21. The plurality of push block springs 25 are respectively placed outside the plurality of shafts 26. The outer wall of the tooth block 24 is slidably connected with the inner wall of the rectangular box 21. The top ends of the two tooth blocks 24 can be respectively engaged with the teeth on the two rotating wheels 16. When the gear rod 15 drives the rotating wheel 16 to rotate, the rotating wheel 16 squeezes the tooth block 24 to move and rotate. Through the tooth ratio, when the oil suction plate 19 is turned over, the teeth on the gear rod 15 will no longer mesh with the teeth on the rotating wheel 16. At this time, the rotating wheel 16 will no longer rotate, and the tooth block 24 will slide out of the moment box 21 through the elastic force of the push block spring 25. The tooth block 24 will be stuck in the middle of the two teeth of the rotating wheel 16 for limit fixing, preventing the rotating wheel 16 from shaking due to the loss of the limiting force of the gear rod 15 when the oil pressure plate 14 is pressed down, thereby affecting the extrusion effect of the oil pressure plate 14 and playing the role of limiting and fixing the oil suction plate 19.

[0031] like Figure 5 to Figure 6 As shown, the tops of the multiple cylinders 8 are all fixedly mounted with oil rings 17, the oil suction plate 19 is rotatably connected to the inner wall of the oil ring 17, a lubricating oil port 23 is provided in the middle of the inner wall of the oil ring 17, the lubricating oil port 23 is an oblique sliding port, the inner wall of the oil ring 17 is provided with a stepped ring port 22, the stepped ring port 22 is an oil placement area, and the multiple oil pressing plates 14 are respectively slidably connected to the inner walls of the multiple oil rings 17; When the oil pressure plate 14 squeezes the oleophilic sponge ring plate on one side of the runner 16, the oil pressure plate 14 squeezes the oil in the oleophilic sponge ring plate to flow around, and the squeezed oil flows into the ladder ring port 22 in the oil ring 17 through the lubricating oil port 23 in the middle of the oil ring 17 for storage, which is convenient for the subsequent collection of the squeezed oil. It should be noted here that the height of the lowest end of the oleophilic sponge ring plate should be flush with the opening of the lowest end of the lubricating oil port 23.

[0032] like Figure 3 to Figure 4 As shown, an oil storage tank 12 is fixedly installed between the outer walls of the plurality of cylinders 8, and an oil flow pipe 18 is provided between the oil storage tank 12 and the plurality of oil rings 17; When the oil enters the ladder ring opening 22, the oil in the ladder ring opening 22 finally flows into the oil storage tank 12 through the oil flow pipe 18 for storage, thereby playing the role of centralized oil storage.

[0033] like Figure 6 to Figure 7 As shown, the inner walls of the plurality of cylinders 8 are fixedly mounted with water-passing plates 11, and the bottom middle positions of the plurality of water-passing plates 11 are fixedly mounted with round blocks 29; When the oleophilic sponge ring plate on one side of the oil absorption plate 19 performs the oil absorption operation, the sewage flows downward from the cylinder 8, finally flows out of the cylinder 8 through the water pass plate 11 and is placed in the clean sewage box 6 for decontamination. By setting a plurality of water flow apertures on the water pass plate 11, the sewage placed in the cylinder 8 has a flow speed that is lower than the flow speed of the oily sewage entering the cylinder 8 when it flows downward, so that the oily sewage can fill the entire cylinder 8 when it is passed in, and the oil in the oily sewage can be placed on the top of the cylinder 8 and absorbed by the oleophilic sponge ring plate on one side of the oil absorption plate 19, thereby playing a role in flow control.

[0034] like Figure 6 to Figure 7 As shown, the inner walls of the multiple cylinders 8 are fixedly mounted with rotating shafts 30, the outer walls of the multiple rotating shafts 30 are symmetrically hinged with water blocking plates 27, the outer walls of the multiple round blocks 29 are symmetrically fixedly mounted with return springs 28, and one end of the multiple return springs 28 is respectively fixed to the bottom of the multiple water blocking plates 27; When the amount of oily sewage introduced into the cylinder 8 accumulates more and more, when the amount of oily sewage accumulates to a certain mass, the sewage will push the water blocking plate 27 through gravity to squeeze the reset spring 28 from rotating and opening on the rotating shaft 30, and the sewage flowing downward through the water passing plate 11 will flow downward from the opening of the water blocking plate 27 into the clean sewage tank 6. When the oil absorption plate 19 turns over and squeezes the oil, the water diversion valve 3 stops passing the oily sewage into the cylinder 8, and the sewage in the cylinder 8 will continue to push the water blocking plate 27 due to its weight. Open and continue to flow downward. When the oily wastewater in the cylinder 8 flows downward to a certain mass, the mass of the oily wastewater will decrease. Through the elastic force of the reset spring 28, the water blocking plate 27 will reset to block the flow of the oily wastewater remaining in the cylinder 8, preventing the oil-containing wastewater from flowing out of the cylinder 8 with the oil when the oil absorption plate 19 is turned over to squeeze the oil, thereby playing the role of blocking the oil. It should be noted here that the height of the floating oil in the oily wastewater remaining in the cylinder 8 is higher than the top of the water pass plate 11.

[0035] Working principle: by passing the oily sewage from the water inlet pipe 4 into the water diverter valve 3, the water diverter valve 3 divides the oily sewage into four streams and passes them into the cylinder 8 through the water flow pipe 5. Since the density of oil is smaller than that of water, when the oily sewage is passed into the cylinder 8, the oil in the oily sewage will float upwards, and the oily sewage is continuously passed into the cylinder 8 through the water diverter valve 3. The oily sewage in the cylinder 8 will fill the entire cylinder 8, and the oil will float on the top of the cylinder 8. At this time, the oleophilic sponge ring plate on one side of the oil absorption plate 19 in the oil collecting assembly absorbs the oil floating on the top of the cylinder 8. The oily sewage is continuously passed into the cylinder 8 through the water inlet pipe 4, and the oleophilic sponge ring plate on one side of the oil absorption plate 19 continuously absorbs the oil, achieving the effect of concentrated oil absorption. The collected oil can be recycled through subsequent treatment, thereby achieving the effect of treating the oil in the oily sewage; When the oleophilic sponge ring plate on one side of the oil absorption plate 19 continues to absorb the oil, the sewage in the oily sewage will be retained in the clean sewage tank 6 through the bottom of the cylinder 8. The decontamination mechanism in the clean sewage tank 6 removes the remaining substances in the oily sewage, so that the oily sewage meets the discharge standard and avoids affecting the ecological environment. By connecting a flow mechanism to the outlet pipe 7, the decontaminated water can be discharged. When the oil flows to the top of the cylinder 8 through the density ratio, the oleophilic sponge ring plate on one side of the oil absorption plate 19 absorbs the oil. When the oil absorption amount of the oil absorption plate 19 reaches a certain level, the water diverter valve 3 stops passing the oily sewage to the cylinder 8, and the runner 16 is driven to rotate. When the runner 16 rotates, the oil absorption plate 19 is turned over in the cylinder 8 through the rotating rod 20. The oleophilic sponge ring plate on one side of the oil absorption plate 19 rotates 180 degrees at the top of the cylinder 8, so that the oleophilic sponge ring plate on one side of the oil absorption plate 19 faces upward, and the oil absorbed in the oleophilic sponge ring plate on one side of the oil absorption plate 19 is removed, thereby achieving the effect of facilitating oil removal. When the oil absorption amount of the oil absorption plate 19 reaches a certain level, the motor 9 drives the screw 10 to rotate, and the slider 13 will move downward from the top of the screw 10. During the movement, the slider 13 drives the oil pressure plate 14 to move downward. Since the oil pressure plate 14 corresponds to the center position of the cylinder 8 and the oil absorption plate 19, when the slider 13 drives the oil pressure plate 14 to move to a certain position, the oil pressure plate 14 squeezes the oleophilic sponge ring plate on one side of the oil absorption plate 19, and the oil absorbed in the oleophilic sponge ring plate on one side of the oil absorption plate 19 will be pressed and flow out from the oleophilic sponge ring plate to extract the oil. Extruding the oleophilic sponge ring plate by the oil pressure plate 14 to extract the oil can save the step of frequently replacing the oleophilic sponge ring plate, which is more conducive to the operation; When the slider 13 drives the oil pressure plate 14 to move downward, the oil pressure plate 14 drives the gear rod 15 to move downward, and the gear rod 15 drives the rotating wheel 16 to rotate through the meshing of teeth, so that the oil absorption plate 19 is turned over, thereby playing the role of flipping the oil absorption plate 19; When the gear rod 15 drives the rotating wheel 16 to rotate, the rotating wheel 16 squeezes the tooth block 24 to move and rotate. Through the tooth ratio, when the oil suction plate 19 is completed, the teeth on the gear rod 15 will no longer mesh with the teeth on the rotating wheel 16. At this time, the rotating wheel 16 will no longer rotate, and the tooth block 24 will slide out of the torque box 21 through the elastic force of the push block spring 25. The tooth block 24 will be stuck in the middle of the two teeth of the rotating wheel 16 to limit and fix it, preventing the rotating wheel 16 from shaking due to the loss of the limiting force of the gear rod 15 when the oil pressure plate 14 is pressed down, affecting the squeezing effect of the oil pressure plate 14, and playing the role of limiting and fixing the oil suction plate 19; When the oil pressing plate 14 presses the oleophilic sponge ring plate on one side of the runner 16, the oil pressing plate 14 squeezes the oil in the oleophilic sponge ring plate to flow around, and the squeezed oil flows into the ladder ring port 22 in the oil placement ring 17 through the lubricating oil port 23 in the middle of the oil placement ring 17 for storage, so as to facilitate the subsequent collection of the squeezed oil; When the oil enters the ladder ring opening 22, the oil in the ladder ring opening 22 finally flows into the oil storage tank 12 through the oil flow pipe 18 for storage, thus playing the role of centralized oil storage; When the oleophilic sponge ring plate on one side of the oil absorption plate 19 performs oil absorption, the sewage flows downward from the cylinder 8, passes through the water-passing plate 11, and finally flows out of the cylinder 8 and is placed in the clean sewage box 6 for decontamination. By setting a plurality of water flow apertures on the water-passing plate 11, the sewage placed in the cylinder 8 flows downward at a speed lower than the flow speed of the oily sewage entering the cylinder 8, so that the oily sewage can fill the entire cylinder 8 when it is passed in, and the oil in the oily sewage can be placed at the top of the cylinder 8 and absorbed by the oleophilic sponge ring plate on one side of the oil absorption plate 19, thereby playing a role in flow control. When the amount of oily sewage passed into the cylinder 8 accumulates more and more, when the amount of oily sewage accumulates to a certain mass, the sewage will push the water blocking plate 27 to squeeze the reset spring 28 through gravity and rotate it from the rotating shaft 30 to open, and the sewage flowing downward through the water pass plate 11 will flow downward from the opening of the water blocking plate 27 into the clean sewage tank 6. When the oil absorption plate 19 is turned over to squeeze the oil, the water diverter valve 3 is stopped from passing the oily sewage into the cylinder 8. Due to its weight, the sewage in the cylinder 8 will continue to push the water blocking plate 27 to open and continue to flow downward. When the oily sewage placed in the cylinder 8 flows downward to a certain mass, the mass of the oily sewage will decrease, and the water blocking plate 27 will be reset by the elastic force of the reset spring 28 to block the flow of the oily sewage remaining in the cylinder 8, so as to prevent the oily sewage from flowing out of the cylinder 8 with oil when the oil absorption plate 19 is turned over to squeeze the oil, thereby playing the role of blocking the oil.
