[0035] Referring to Figure 2In the embodiment, the inner part of the oil scraping plate 5 is provided with a transverse groove 6 along the length direction of the plate body, the transverse groove 6 is communicated with the sedimentation tank 1 through a plurality of notches provided on the bottom plate of the oil scraping plate 5 at intervals, and a plurality of vibration rods 7 are vertically and spacedly arranged in the transverse groove 6 to synchronously drive the sewage in the sedimentation tank 1 to vibrate.

[0036] Referring to Figures 2-4 In the embodiment, the oil skimming member 8 comprises a collecting plate 81 fixed radially along the sedimentation tank 1, the top of the plate body of the collecting plate 81 is higher than the liquid level of the sewage in the sedimentation tank 1, the bottom plate of the oil scraping plate 5 is spaced from the top plate of the collecting plate 81, one side of the plate body of the oil scraping plate 5 is a slope, and the slope has the movement stroke of extruding the collecting plate 81 and lifting the oil scraping plate 5 during the rotation of the oil scraping plate 5 around the power system 2 following the oil skimming rod 4; The collecting plate 81 is provided with a sewage discharge pipe 83 at the end away from the power system 2, the sewage discharge pipe 83 extends out of the sedimentation tank 1, the collecting plate 81 is provided with an inclined chute 82, the inclined chute 82 is communicated with the sewage discharge pipe 83, and the depth of the inclined chute 82 near the end of the sewage discharge pipe 83 is greater than the depth of the inclined chute 82 near the end of the power system 2.

[0037] The oil skimming member 8 further comprises elastic fixing members, the elastic fixing members have two and are respectively installed at the two ends of the top plate of the oil scraping plate 5; The elastic fixing members comprise a fixed plate 84, a fixed rod 85, a transverse plate 86, a circular plate 87 and a fixed spring 88; The transverse plate 86 is sleeved on the end of the oil skimming rod 4, the fixed rod 85 has two and respectively penetrates through the two ends of the transverse plate 86 and is connected to the fixed plate 84 below the transverse plate 86, the fixed spring 88 is sleeved on the outside of the fixed rod 85, and the circular plate 87 is fixed on the top of the fixed rod 85.

[0038] In this way, the oil skimming rod 4 drives the oil scraping plate 5 to rotate synchronously, the oil scraping plate 5 rubs against the collecting plate 81, the collecting plate 81 collects and discharges the floating matter on the surface of the sewage, and specifically: When the skimming rod 4 rotates around the center of the sedimentation tank 1 under the driving of the power system 2, the skimming rod 4 moves together with the elastic fixing members at both ends of the skimming rod 4, and further drives the oil scraping plate 5 fixed thereto to move together, that is, the oil scraping plate 5 moves along the rotating track of the skimming rod 4 on the liquid surface of the sedimentation tank 1 to realize directional scraping of floating objects on the liquid surface. In the moving process of the oil scraping plate 5, the oil scraping plate 5 exerts a squeezing action on the floating objects on the surface of the sewage, pushes the floating objects to move on the liquid surface of the sewage, and gradually moves towards the collecting plate 81. When the oil scraping plate 5 continuously moves and passes through the collecting plate 81, the floating objects enter the chute 82 of the collecting plate 81 under the pushing of the oil scraping plate 5, slide into one end of the sewage discharge pipe 83 along the chute 82, and finally realize the centralized collection and discharge of the floating objects. The oil scraping plate 5 automatically rises when passing through the collecting plate 81, and specifically: Since the top of the plate body of the collecting plate 81 is higher than the height of the liquid surface of the sewage in the sedimentation tank 1, and there is a certain distance between the bottom of the oil scraping plate 5 and the top of the collecting plate 81, when the oil scraping plate 5 passes through the collecting plate 81, the inclined surface of the oil scraping plate 5 will squeeze on the collecting plate 81 and gradually lift the oil scraping plate 5 through the inclined surface. At the same time, the fixed rod 85 slides at both ends of the horizontal plate 86, and the fixed spring 88 starts to compress. When the oil scraping plate 5 is lifted to a certain height, its bottom will slowly pass through the collecting plate 81. In the process of passing through the collecting plate 81, the fixed spring 88 will slowly release the elastic force, thereby driving the fixed rod 85 to slowly reset at both ends of the horizontal plate 86, so that the oil scraping plate 5 returns to the initial height, thereby realizing the automatic lifting function of the oil scraping plate 5 when passing through the collecting plate 81, ensuring the smooth operation of the oil scraping plate 5 without affecting the collection effect. Its role is to effectively avoid the situation that the oil scraping plate 5 is stuck or damaged due to excessive resistance during operation, while ensuring the continuity and stability of the entire skimming process. This structure design not only improves the working efficiency of the equipment, but also prolongs the service life of the equipment, and has good application prospect and popularization value.

[0039] Referring to Figures 5-7 In this embodiment, the vibration assembly 9 includes a driving member 11 mounted on the oil scraping plate 5 for driving the plurality of vibration rods 7 to vibrate synchronously. The driving member 11 includes a support frame 111, a driving motor 112, a driving shaft 113 and a driving plate 114. The support frame 111 is mounted on the top plate of the oil scraping plate 5, the driving motor 112 is fixed by the support frame 111, the driving shaft 113 is fixed at the output end of the driving motor 112 and extends inwardly into the horizontal groove 6, and the driving plate 114 is located in the horizontal groove 6 and has an S-shaped structure and is fixedly sleeved on the driving shaft 113 with the center point of the S-shaped structure as the center.

[0040] The vibration assembly 9 further comprises a striking piece 12, which has two symmetrical striking pieces 12 installed in the oil skimmer 5 respectively with the driving piece 11 as the center, for striking a plurality of vibration rods 7 and generating vibration; The striking piece 12 comprises a striking plate 121, a limiting plate 123 and a striking rod 124; The limiting plate 123 is parallel to the oil skimmer 5 and is fixed in the middle of the top of the inner wall of the transverse groove 6, the striking plate 121 is fixed in the transverse groove 6, and a limiting groove 122 is formed in the top along the length direction of the plate body, the limiting groove 122 is matched with the limiting plate 123 through sliding clamping, and the striking rod 124 has a plurality of striking rods 124 respectively distributed on both sides of the striking plate 121, and each striking rod 124 is inserted between two adjacent vibration rods 7 and is in contact with the vibration rod 7 close to the driving piece 11.

[0041] The vibration assembly 9 further comprises a power compression piece 13, which has two power compression pieces 13 respectively corresponding to each striking piece 12, for providing elastic striking power; The power compression piece 13 comprises a guide rod 132 and a guide spring 133; A guide groove 131 is formed in the striking plate 121 along the length direction of the plate body, one end of the guide rod 132 is fixed to the inner wall of the oil skimmer 5, the other end is inserted into the guide groove 131, and the guide groove 131 is matched with the guide groove 131 through sliding, the guide spring 133 is sleeved outside the guide rod 132, one end is fixed to the inner wall of the oil skimmer 5, and the other end is fixed to the end of the striking plate 121 away from the driving piece 11.

[0042] In this way, when the staff starts the power system 2, the driving motor 112 can be started at the same time, the driving motor 112 drives the driving shaft 113 at the output end to rotate, and the driving plate 114 rotates with the driving shaft 113. Since the driving plate 114 is S-shaped, when the driving plate 114 rotates, the driving plate 114 will move the two striking plates 121 through its special shape, which can make the two striking plates 121 reciprocate inside the oil skimmer 5, thereby driving the two striking pieces 12 to strike, so that the plurality of vibration rods 7 vibrate inside the oil skimmer 5, thereby effectively stirring the sewage in the transverse groove 6, making the oil stains in the sewage more easily separated, and improving the oil skimming efficiency and quality. The S-shaped driving plate 114 can exert periodic force on the striking plate 121 according to different rotation angles, so that the striking piece 12 forms a stable vibration frequency inside the oil skimmer 5, further ensuring that the vibration rod 7 continuously and efficiently disturbs the sewage, and enhancing the uniformity and completeness of oil stain separation.

[0043] Further, in the process of being poked by the driving plate 114, the plurality of impact rods 124 on both sides of the impact plate 121 gradually move away from the corresponding vibration rods 7, and when the impact rods 124 are separated from the driving plate 114 and quickly rebound under the action of the guide spring 133, they will collide with the vibration rods 7, thereby driving the vibration rods 7 to vibrate at a high frequency. These vibrations are transmitted to the sewage through the vibration rods 7, and the suspended particles in the sewage gradually gather and float to the liquid surface under the action of vibration, forming a scum layer that is easy to scrape off. The oil stains in the sewage are more easily separated from the water surface under the action of vibration, thereby improving the overall oil removal efficiency. During the entire reciprocating movement of the impact plate 121, the limiting plate 123 arranged at the top of the horizontal groove 6 limits the movement range of the impact plate 121 through the limiting groove 122, ensuring that the impact plate 121 moves stably within the specified range without deviation or jamming, thereby ensuring the stability and continuity of the entire oil-water separation.

[0044] Referring to Figure 5 and Figure 8 In the present embodiment, the gathering assembly 10 comprises a transmission member 14 mounted on the top plate of the oil scraping plate 5 for transmitting the power generated by the driving member 11. The transmission member 14 comprises a first gear 141, a transmission shaft 142, a second gear 143, and a transmission plate 144. The first gear 141 is fixedly sleeved on the driving shaft 113, the transmission shaft 142 is rotatably arranged on one side of the driving shaft 113, the second gear 143 is fixedly sleeved on the transmission shaft 142 and is in meshing and matching with the first gear 141, and the radius of the second gear 143 is smaller than that of the first gear 141. The transmission plate 144 is fixedly sleeved on the top of the transmission shaft 142 and rotates synchronously with the transmission shaft 142, and the transmission plate 144 is in an elliptical structure, and transmission grooves 145 are formed in the top and bottom along the circumference.

[0045] In this way, the driving shaft 113 drives the driving plate 114 to rotate, and also drives the first gear 141 to rotate. The second gear 143 is in meshing transmission with the first gear 141 and rotates synchronously. Since the radius of the second gear 143 is smaller than that of the first gear 141, the rotation speed of the second gear 143 is faster than that of the first gear 141. The purpose is to improve the overall transmission efficiency and realize speed conversion, so as to better adapt to the operation requirements of the subsequent components. The second gear 143 rotates and drives the transmission shaft 142 at the shaft center to rotate. When the transmission shaft 142 rotates, the transmission plate 144 rotates with the transmission shaft 142. When the transmission plate 144 rotates, the two parallel transmission grooves 145 opened at the top and bottom of the transmission plate 144 rotate along the rotation path of the transmission plate 144. Through the radius difference between the first gear 141 and the second gear 143, the transmission speed is gradually amplified, the rotation frequency of the transmission plate 144 is improved, the movement track of the transmission groove 145 is more intensive, and the driving effect on the subsequent connecting components is enhanced.

[0046] Referring to Figure 5 、 Figures 9-11 In the embodiment, the gathering assembly 10 further comprises pneumatic members 15, which are symmetrically installed on the top plate of the oil scraping plate 5 with the transmission member 14 as the center, and are used for generating airflow and blowing the floating objects on the sewage surface towards the center of the oil scraping plate 5; The pneumatic member 15 comprises a ball 151, a pneumatic frame 152, a pneumatic rod 153, a pressing plate 154, a pressing pipe 155, an exhaust pipe 156, an exhaust one-way valve 158, an air inlet pipe 159 and an air inlet one-way valve 1510. The pneumatic rod 153 is telescopically installed at the head end of the exhaust pipe 156. The pressing plate 154 is fixed at one end of the pneumatic rod 153 and extends into the pressing pipe 155. The pressing plate 154 and the pressing pipe 155 are slidingly matched, and the outer diameter of the plate body matches the inner diameter of the pipe body. The pneumatic frame 152 is symmetrically fixed at the other end of the pneumatic rod 153. The ball 151 is rollingly embedded in the inner wall of the end of each pneumatic frame 152 and is slidingly and detachably connected with the upper and lower transmission grooves 145. The exhaust pipe 156 is communicatively installed at the tail end of the exhaust pipe 156. The tail end of the exhaust pipe 156 is uniformly and spacedly provided with a plurality of exhaust holes 157. The exhaust one-way valve 158 is opened in the exhaust pipe 156 and the opening direction faces the tail end of the pressing pipe 155. The air inlet pipe 159 is opened in the pressing pipe 155.

[0047] In this way, the ball 151 rotates in the transmission groove 145 and reciprocally rolls along the elliptical movement track of the transmission groove 145 and the transmission plate 144. When the ball 151 moves in the transmission groove 145, the pneumatic rod 153 reciprocally moves under the connection and conduction of the pneumatic frame 152, and drives the pressing plate 154 to reciprocally move in the pressing pipe 155.

Conversely, when the extrusion plate 154 moves reversely with the pneumatic rod 153, the air inlet one-way valve 1510 is closed, and the exhaust one-way valve 158 is opened. At this time, the air in the extrusion pipe 155 will enter the exhaust pipe 156 through the exhaust one-way valve 158, and be discharged through the plurality of exhaust holes 157 located at one end of the exhaust pipe 156; The two exhaust pipes 156 respectively pass out of the fixed plate 84 arranged on the oil scraping plate 5, and one exhaust pipe 156 close to the power system 2 is in an arc structure, which is used to better fit the running track of the oil scraping plate 5, so that the air flow can accurately act on the oil scraping area, further improve the efficiency of floating oil collection, and avoid the floating oil from gathering at the axis of the settling tank 1, so as to ensure that the floating oil can be continuously collected and discharged by the oil scraping plate 5. The plurality of exhaust holes 157 are respectively located on the opposite sides of the two exhaust pipes 156 and are inclined at 45°. In this way, the air flow discharged from the exhaust hole 157 blows towards the sewage liquid surface, so that the floating oil on the sewage liquid surface is driven by the air flow to accelerate the gathering, and the air flow forms a small disturbance on the sewage liquid surface, which helps to further break the oil-water interfacial tension, thereby improving the separation efficiency.
