Currently, most of the sewage separation equipment in the existing technologies can only separate the floating oil in the sewage or separate the sludge in the sewage, and cannot simultaneously separate the floating oil and sludge in the sewage, resulting in inconvenient separation of the floating oil and sludge in the sewage;

One end of the driving rod 32 away from the rotating disc 31 is rotatably connected to one end of the push rod 27. The driving rod 32 can make the push rod 27 reciprocate.

[0036] By adopting the above technical solution, by setting the first fixing block 29, the first fixing block 29 supports the servo motor 28 to improve the stability of the servo motor 28. By starting the servo motor 28, the driving shaft of the servo motor 28 makes the first rotating rod 3 rotate. The first rotating rod 3 makes the driving rod 32 rotate around the axis of the rotating disc 31 through the rotating disc 31. The driving rod 32 makes the push rod 27 reciprocate.

[0037] The oil removal mechanism 4 includes a hollow drain pipe 41. The hollow drain pipe 41 penetrates through the sealing ring 18 and is in movable contact with the inner wall of the sealing ring 18. By setting the sealing ring 18, the sealing ring 18 can improve the sealing performance between the hollow drain pipe 41 and the processing pool 17.

The floating oil on the upper surface inside the processing pool 17 can enter the inside of the hollow drain pipe 41 through the oil inlet grooves 42. On the side of the processing table 1 away from the processing pool 17, an electric telescopic rod 44 is fixedly installed. The piston end of the electric telescopic rod 44 is fixedly connected to one end of the hollow drain pipe 41. By starting the electric telescopic rod 44, the piston end of the electric telescopic rod 44 can make the hollow drain pipe 41 lift and lower in the vertical direction. One end of the hollow drain pipe 41 close to the oil inlet grooves 42 is fixedly installed with a substrate 46. The hollow drain pipe 41 can make the substrate 46 lift and lower synchronously.

[0038] By adopting the above technical solution, by setting the sealing ring 18, the sealing ring 18 improves the sealing performance between the hollow drain pipe 41 and the processing pool 17. By starting the electric telescopic rod 44, the piston end of the electric telescopic rod 44 makes the hollow drain pipe 41 lift and lower in the vertical direction. The hollow drain pipe 41 makes the substrate 46 lift and lower synchronously. By opening the oil inlet grooves 42, the floating oil on the upper surface inside the processing pool 17 enters the inside of the hollow drain pipe 41 through the oil inlet grooves 42.

One end of the electric telescopic rod 44 far from the hollow drain pipe 41 is fixedly installed with a second fixing block 45. One side of the treatment table 1 far from the treatment tank 17 is fixedly connected to the second fixing block 45. The second fixing block 45 can support and fix the electric telescopic rod 44.

[0040] By adopting the above technical solution, when the floating oil on the upper surface inside the treatment tank 17 enters the inside of the hollow drain pipe 41 through the oil inlet tank 42, the floating oil in the hollow drain pipe 41 is discharged through the discharge pipe 43. By setting the second fixing block 45, the second fixing block 45 supports and fixes the electric telescopic rod 44.

[0041] The oil scraping mechanism 5 includes two oil scraping plates 51. When the two oil scraping plates 51 move towards each other, the two oil scraping plates 51 can make the floating oil on the upper surface inside the treatment tank 17 flow towards the position of the hollow drain pipe 41. Semi-circular grooves 52 are formed on the opposite sides of the two oil scraping plates 51. By providing the semi-circular grooves 52, when the opposite sides of the two oil scraping plates 51 are in contact, the inner walls of the two semi-circular grooves 52 are in contact with the outer wall of the hollow drain pipe 41. Uniformly distributed guide grooves 53 are formed on the upper surface of the substrate 46. Guide blocks 54 are slidably connected to the inner walls of the guide grooves 53. The guide blocks 54 can slide horizontally along the inner walls of the guide grooves 53. Moving seats 55 are fixedly installed on the upper surfaces of adjacent two guide blocks 54. The guide blocks 54 can keep the moving seats 55 moving in the horizontal direction.

The moving seat 55 can make the oil scraping plate 51 move in the horizontal direction. Notches 56 are formed in the inner walls of the two moving seats 55.

[0042] By adopting the above technical solution, by providing the guide grooves 53 and the guide blocks 54, the guide blocks 54 keep the moving seats 55 moving in the horizontal direction. By driving the moving seats 55 to move in the horizontal direction, the moving seats 55 make the oil scraping plates 51 move in the horizontal direction. When the two oil scraping plates 51 move towards each other, the two oil scraping plates 51 make the floating oil on the upper surface inside the treatment tank 17 flow towards the position of the hollow drain pipe 41, accelerating the flow of the floating oil, and thus accelerating the speed of separation of the floating oil from the sewage.

[0043] The upper surface of the base plate 46 is rotatably mounted with two second rotating rods 57 and a third rotating rod 571, one end of each of the two second rotating rods 57 and the two third rotating rods 571 is fixedly mounted with a transmission wheel 58, and a transmission belt 59 is connected between two adjacent transmission wheels 58. The two second rotating rods 57 and the two third rotating rods 571 can transmit the two transmission belts 59 through the corresponding transmission wheels 58, and the outer walls of the two transmission belts 59 are fixedly mounted with moving blocks 591, and the upper surfaces of the two moving blocks 591 are fixedly mounted with There is a synchronization rod 592, and the transmission belt 59 can make the synchronization rod 592 move horizontally through the moving block 591. The end of the synchronization rod 592 away from the moving block 591 is in active contact with the inner wall of the slot 56. The synchronization rod 592 can make the moving seat 55 move back and forth horizontally through the slot 56. It should be noted that one moving block 591 is fixed on one side of a corresponding transmission belt 59, and the other moving block 591 is fixed on the other side of a corresponding transmission belt 59, so that the two moving seats 55 can move back and forth toward each other or back and forth away from each other.

[0044] By adopting the above technical solution, by driving the two second rotating rods 57 to rotate, the two second rotating rods 57 and the two third rotating rods 571 transmit the two transmission belts 59 through the corresponding transmission wheels 58, the transmission belt 59 causes the synchronization rod 592 to move horizontally through the moving block 591, and the synchronization rod 592 causes the moving seat 55 to reciprocate horizontally through the slot 56.

[0045] Two transmission rods 6 are provided on the lower surface of the base plate 46. Two support plates 61 are fixedly installed on the lower surface of the base plate 46. The transmission rod 6 penetrates the support plate 61 and is rotatably connected to the support plate 61. The base plate 46 can make the transmission rod 6 rise and fall synchronously in the vertical direction through the support plate 61. At the same time, the support plate 61 can support the transmission rod 6. One end of the two transmission rods 6 and the two second rotating rods 57 are fixedly installed with bevel gears 62. The two adjacent bevel gears 62 are meshed with each other. The transmission rod 6 can rotate the second rotating rod 57 through the two meshing bevel gears 62. The other ends of the two transmission rods 6 are fixedly installed with transmission gears 63. The transmission gear 63 can rotate the transmission rod 6. Two tooth plates 64 are fixedly installed on the inner wall of the treatment pool 17. The tooth plate 64 and the transmission gear 63 are meshed and connected. When the transmission rod 6 is lifted in the vertical direction, the transmission rod 6 makes the transmission gear 63 rise and fall synchronously, and the tooth plate 64 drives the transmission gear 63 to rotate.

[0046] By adopting the above technical solution, when the base plate 46 is lifted or lowered in the vertical direction, the base plate 46 causes the transmission rod 6 and the transmission gear 63 to be lifted or lowered in the vertical direction synchronously through the support plate 61, the gear plate 64 drives the transmission gear 63 to rotate, the transmission gear 63 causes the transmission rod 6 to rotate, and the transmission rod 6 causes the second rotating rod 57 to rotate through two mutually meshing bevel gears 62.

[0047] Working principle: When it is necessary to separate sludge and floating oil from sewage, the staff first make a certain amount of sewage enter the inside of the treatment tank 11 through the water inlet pipe 13. At this time, the first filter plate 15 filters the sludge in the sewage and makes the sludge stay inside the treatment tank 11. At the same time, the sewage from which the sludge has been separated drips into the inside of the treatment pool 17 through the second filter plate 16;

[0048] At the same time, by turning on the servo motor 28, the drive shaft of the servo motor 28 makes the first rotating rod 3 rotate. The first rotating rod 3 makes the driving rod 32 rotate around the axis of the rotating disk 31 through the rotating disk 31. The driving rod 32 makes the push rod 27 move reciprocally. The push rod 27 makes the mud pressing plate 21 move horizontally reciprocally through the connecting sleeve 26, the rotating shaft 25 and the U-shaped seat 24. At the same time, the piston ends of the two guide rods 23 extend or contract as the mud pressing plate 21 moves horizontally reciprocally. During the process of moving horizontally reciprocally, the mud pressing plate 21 continuously contacts the side surface of the first filter plate 15 and compresses the sludge staying in the treatment tank 11, thus conveniently realizing the separation of the sludge from the sewage and the compression of the sludge, and effectively improving the convenience of subsequent sludge treatment. At the same time, the efficiency of separating the sludge from the sewage is improved;

[0049] As the sewage liquid level in the treatment pool 17 rises, when the rising height of the sewage liquid level reaches the height of the multiple oil inlet grooves 42, the floating oil on the upper surface of the sewage flows into the hollow oil discharge pipe 41 through the multiple oil inlet grooves 42 and is discharged through the discharge pipe 43. At the same time, by keeping the drain pipe 191 in an open state, the sewage in the treatment pool 17 is discharged through the drain pipe 191. At this time, the liquid level height in the treatment pool 17 drops;

[0050] Meanwhile, by activating the electric telescopic rod 44, the piston end of the electric telescopic rod 44 contracts, causing the hollow oil drain pipe 41 to descend vertically. At the same time, the hollow oil drain pipe 41 causes the substrate 46 to descend synchronously. The substrate 46 causes the two transmission rods 6 and the two transmission gears 63 to descend synchronously through the two support plates 61. At this time, the two toothed plates 64 drive the two transmission gears 63 to rotate. The two transmission gears 63 cause the two transmission rods 6 to rotate. The two transmission rods 6 cause the two second rotating rods 57 to rotate through the two meshing bevel gears 62. The two second rotating rods 57 and the two third rotating rods 571 cause the two transmission belts 59 to transmit through the corresponding transmission wheels 58. The two transmission belts 59 cause the two synchronizing rods 592 to move horizontally through the two moving blocks 591. The two synchronizing rods 592 cause the two moving seats 55 to reciprocate horizontally through the two notches 56. At this time, the two moving seats 55 cause the two oil scraping plates 51 to reciprocate horizontally. The two oil scraping plates 51 approach or move away from each other. When the two oil scraping plates 51 approach each other, the two oil scraping plates 51 cause the floating oil on the upper surface inside the treatment tank 17 to flow towards the position of the hollow oil drain pipe 41, thus conveniently realizing the separation of the floating oil from the sewage and the accelerated flow of the floating oil, and further effectively improving the separation speed of the floating oil from the sewage.
