[0059] Further comprising:

[0060] An oil scraping plate 5 is arranged below the oil skimming rod 4 and rotates synchronously with the oil skimming rod 4, for pushing the scum and oil on the surface of the sewage in the sedimentation tank 1.

[0062] A vibration assembly 9 is arranged in the oil scraping plate 5 to drive the vibration rods 7 to vibrate to break and collect the emulsified oil particles in the sewage;

[0063] A gathering assembly 10 is arranged above the oil scraping plate 5 to generate air flow to blow the surface of the sewage by wind force to drive the scum and oil to gather towards the center of the oil scraping plate 5.

[0064] Referring to Figure 2 In the embodiment, a horizontal groove 6 is formed in the oil scraping plate 5 along the length direction of the plate body, the horizontal groove 6 is communicated with the settling tank 1 through a plurality of notches arranged on the bottom plate of the oil scraping plate 5 at intervals, and the vibration rods 7 are vertically arranged in the horizontal groove 6 to simultaneously drive the sewage in the settling tank 1 to vibrate.

[0065] Referring to Figures 2-4 In the embodiment, the oil skimming member 8 includes a collecting plate 81 fixed along the radial direction of the settling tank 1, the top of the plate body of the collecting plate 81 is higher than the liquid level of the sewage in the settling tank 1, and the bottom plate of the oil scraping plate 5 is spaced apart 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 a movement stroke of pressing 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.

[0066] 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 settling tank 1, the collecting plate 81 is provided with an inclined groove 82, the inclined groove 82 is communicated with the sewage discharge pipe 83, and the depth of the inclined groove 82 near the end of the sewage discharge pipe 83 is greater than the depth of the inclined groove 82 near the end of the power system 2.

[0067] The oil skimming member 8 further includes two elastic fixing members installed at the two ends of the top plate of the oil scraping plate 5.

[0068] The elastic fixing members include a fixing plate 84, a fixing rod 85, a horizontal plate 86, a circular plate 87 and a fixing spring 88.

[0069] The transverse plate 86 is sleeved on the end of the oil skimming rod 4, the fixed rod 85 has two ends respectively penetrating through the two ends of the transverse plate 86 and being connected to the fixed plate 84 below the transverse plate 86, and the fixed spring 88 is sleeved outside the fixed rod 85, and the circular plate 87 is fixed on the top of the fixed rod 85.

[0070] In this way, the oil skimming rod 4 drives the oil scraping plate 5 to rotate synchronously, the oil scraping plate 5 is scraped with the collecting plate 81, the collecting plate 81 collects and discharges the floating objects on the surface of the sewage, and specifically:

[0071] When the oil skimming rod 4 rotates around the center of the sedimentation tank 1 under the driving action of the power system 2, the oil skimming rod 4 drives the elastic fixing members at the two ends to move, and further drives the oil scraping plate 5 fixed thereto to move, that is, the oil scraping plate 5 moves along the rotation track of the oil skimming rod 4 on the liquid surface of the sedimentation tank 1, so that the floating objects on the liquid surface are scraped in a targeted manner, in the moving process of the oil scraping plate 5, the oil scraping plate 5 exerts a pressing action on the floating objects on the surface of the sewage, so as to push the floating objects to move on the liquid surface of the sewage and gradually move 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 action of the oil scraping plate 5, the floating objects slide into one end of the sewage discharge pipe 83 along the chute 82, and finally the floating objects are collected and discharged in a concentrated manner;

[0072] When the oil scraping plate 5 passes through the collecting plate 81, the oil scraping plate 5 automatically rises and falls, and specifically:

[0073] 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 is pressed on the collecting plate 81 and gradually lifts the oil scraping plate 5 through the inclined surface, at the same time, the fixed rod 85 slides at the two ends of the transverse plate 86, and the fixed spring 88 starts to compress, when the oil scraping plate 5 is lifted to a certain height, the bottom of the oil scraping plate 5 slowly passes through the collecting plate 81, in the process of passing through the collecting plate 81, the fixed spring 88 slowly releases the elastic force, so as to drive the fixed rod 85 to slowly reset at the two ends of the transverse plate 86, so that the oil scraping plate 5 returns to the initial height, thereby realizing the automatic rising and falling function of the oil scraping plate 5 when passing through the collecting plate 81, ensuring that the oil scraping plate 5 smoothly runs without affecting the collecting effect, which can effectively avoid the situation that the oil scraping plate 5 is stuck or damaged due to excessive resistance in the running process, and at the same time ensures the continuity and stability of the whole oil skimming process, the structure design not only improves the working efficiency of the equipment, but also prolongs the service life, and has good application prospect and popularization value.

[0074] Referring to Figures 5-7In the embodiment, the vibration assembly 9 comprises a driving member 11 mounted on the oil scraping plate 5 for driving the plurality of vibration rods 7 to vibrate synchronously.

[0075] The driving member 11 comprises a support frame 111, a driving motor 112, a driving shaft 113 and a driving plate 114.

[0076] 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 transverse groove 6, and the driving plate 114 is located in the transverse groove 6 and is fixed on the driving shaft 113 with the center point of the S-shaped structure as the center.

[0077] The vibration assembly 9 further comprises two impact members 12 symmetrically mounted in the oil scraping plate 5 with the driving member 11 as the center for impacting the plurality of vibration rods 7 and generating vibration.

[0078] The impact member 12 comprises an impact plate 121, a limiting plate 123 and an impact rod 124.

[0079] The limiting plate 123 is parallel to the oil scraping plate 5 and is fixed at the top of the inner wall of the transverse groove 6, the impact plate 121 is fixed in the transverse groove 6, a limiting groove 122 is formed in the top along the length direction of the plate body, the limiting groove 122 and the limiting plate 123 are slidingly matched, and the impact rod 124 has a plurality of impact rods 124 distributed on both sides of the impact plate 121 at intervals, and each impact rod 124 is inserted between two adjacent vibration rods 7 and contacts the vibration rod 7 close to the driving member 11.

[0080] The vibration assembly 9 further comprises two power compression members 13 corresponding to each impact member 12 for providing elastic impact power.

[0081] The power compression member 13 comprises a guide rod 132 and a guide spring 133.

[0082] A guide groove 131 is formed in the impact 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 scraping plate 5, the other end is inserted into the guide groove 131 and is slidingly matched with the guide groove 131, and the guide spring 133 is sleeved on the outside of the guide rod 132, one end is fixed to the inner wall of the oil scraping plate 5, and the other end is fixed to the end of the impact plate 121 away from the driving member 11.

[0083] In this way, when the staff starts the power system 2, the driving motor 112 is started at the same time, and 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 actuate the two impact plates 121 through its special shape, which can make the two impact plates 121 reciprocate inside the oil scraping plate 5, thereby driving the two impact pieces 12 to impact, so that the plurality of vibration rods 7 vibrate inside the oil scraping plate 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 impact plate 121 according to different rotation angles, so that the impact piece 12 forms a stable vibration frequency inside the oil scraping plate 5, further ensuring that the vibration rod 7 continuously and efficiently disturbs the sewage, enhancing the uniformity and completeness of oil stain separation.

[0084] Further, in the process of driving the impact plate 121 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 rod 7. When the impact rod 124 is separated from the driving plate 114 and rapidly rebounds under the action of the guide spring 133, it will collide with the vibration rod 7, thereby driving the vibration rod 7 to vibrate at a high frequency. These vibrations will be transmitted to the sewage through the vibration rod 7, thereby causing the suspended particles in the sewage to gradually accumulate and float to the 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 motion of the impact plate 121, the limiting plate 123 arranged at the top of the transverse 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.

[0085] Referring to Figure 5 and Figure 8 In this embodiment, the gathering assembly 10 includes a transmission member 14 mounted on the top plate of the oil scraping plate 5 for transmitting power generated by the driving member 11.

[0086] The transmission member 14 includes a first gear 141, a transmission shaft 142, a second gear 143, and a transmission plate 144.

[0087] 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 matching with the first gear 141, and the second gear 143 has a smaller radius than 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 has an elliptical structure and is provided with transmission grooves 145 on the top and the bottom in the circumferential direction.

[0088] In this way, the driving shaft 113 drives the driving plate 114 to rotate, and the first gear 141 rotates, the second gear 143 rotates synchronously in meshing transmission with the first gear 141, and the second gear 143 rotates faster than the first gear 141 due to the smaller radius of the second gear 143, so as to improve the overall transmission efficiency and realize speed conversion, thereby better adapting to the operation requirements of subsequent components.
