[0015] A method for energy-saving sewage treatment equipment, comprising the following steps:

[0016] S1: When treating sewage, sewage and flocculants are first put into the main body of the treatment device, and then it is left to stand. After standing, an oil film floats on the surface of the sewage. Then the fan and the motor are started. When the fan is driven, the inside of the pipeline is under negative pressure, and external gas enters the pipeline and is finally discharged from the outlet into the sewage to accelerate the separation of oil and water.

[0017] S2: When the motor is driven, the first rotating shaft rotates slowly, the rotation of the first rotating shaft drives the moving seat to rotate, the rotation of the moving seat drives the installation top seat, the installation base and the oil absorbent cloth to rotate, so that the oil absorbent cloth moves at the sewage surface to absorb the oil on the sewage surface.

[0018] S3: When the first rotating shaft drives the reciprocating screw to rotate under the bracket during the rotation process, the rotation of the reciprocating screw drives the first gear to rotate about the axis of the first rotating shaft, and the first gear rotates itself when it moves and meshes with the gear block.

The movement of the moving plate drives the movement of the moving seat, and the movement of the moving seat drives the movement of the mounting top seat and the mounting base, so that the oil absorbent cloth moves up and down at the sewage surface, allowing the oil absorbent cloth to fully absorb the oil stains;

[0019] S4: When the reciprocating screw rotates, it drives the second gear to rotate, the rotation of the second gear drives the rotation of the third gear, the rotation of the third gear drives the rotation of the connecting block, the rotation of the connecting block drives the rotation of the second rotating shaft, the rotation of the second rotating shaft drives the rotation of the first bevel gear, the rotation of the first bevel gear drives the rotation of the second bevel gear, the rotation of the second bevel gear drives the rotation of the installation roller, so that the installation roller inside the installation base rotates to reel up the oil absorbent cloth, and the oil absorbent cloth inside the installation top seat is unwound, so as to perform continuous operation.

[0020] The beneficial effects of the present invention are as follows:

[0021] 1. The present invention arranges an oil scraper assembly. When treating sewage, sewage and flocculant are firstly put into the treatment device body, and then the device is allowed to stand. After the device stands, an oil film floats on the surface of the sewage. Then, the first rotating shaft is driven by a motor to rotate slowly. The rotation of the first rotating shaft drives the moving seat to rotate. The rotation of the moving seat drives the installation top seat, the installation base and the oil absorbent cloth to rotate, so that the oil absorbent cloth moves at the sewage liquid surface to absorb the oil on the sewage surface, thereby improving the sewage treatment efficiency.

[0022] 2. The present invention arranges a moving component. When the first rotating shaft drives the reciprocating screw to rotate below the bracket during rotation, the rotation of the reciprocating screw drives the first gear to rotate about the axis of the first rotating shaft. When the first gear moves and engages with the tooth block, it rotates itself. The rotation of the first gear drives the rotation of the reciprocating screw. The rotation of the reciprocating screw drives the moving plate to move up and down. The movement of the moving plate drives the movement of the moving seat. The movement of the moving seat drives the movement of the mounting top seat and the mounting base, so that the oil absorbent cloth moves up and down at the sewage surface, allowing the oil absorbent cloth to fully absorb the oil, thereby increasing the oil absorption area and time, and improving the oil absorption efficiency.

[0023] 3. The present invention adopts the setting of the aeration component. When treating sewage, the fan drives the inside of the pipeline to create a negative pressure, and the external gas enters the pipeline and is finally discharged into the sewage from the air outlet. The buoyancy is increased by the adhesion of oil droplets to highly dispersed microbubbles, thereby increasing the floating speed and improving the oil-water separation efficiency.

[0037] like Figures 1 to 7 As shown, a mounting block 9 is provided at one end of the mounting top seat 5 , and the mounting block 9 is embedded in the outer wall of the mounting roller 8 and is threadedly connected to the mounting roller 8 .

[0038] The mounting block 9 is removed by rotating it, and the oil-absorbing cloth 7 on the outer wall of the mounting roller 8 is taken out for replacement.

[0039] like Figure 5 As shown, the moving assembly includes a moving plate 11 fixedly mounted on the top of the moving seat 4, the internal thread of the moving plate 11 is connected to a reciprocating screw 12, the reciprocating screw 12 is rotatably mounted inside the first rotating shaft 3, the top of the reciprocating screw 12 is fixedly connected to a first gear 13, one side of the first gear 13 is meshedly connected to a tooth block 14, the tooth block 14 is fixedly mounted inside a bracket 15, and the bracket 15 is fixedly mounted on the top of the processing device body 1.

[0040] When the first rotating shaft 3 rotates, it drives the reciprocating screw 12 to rotate under the bracket 15. The rotation of the reciprocating screw 12 drives the first gear 13 to rotate about the axis of the first rotating shaft 3. The first gear 13 rotates itself when it moves to engage with the tooth block 14. The rotation of the first gear 13 drives the rotation of the reciprocating screw 12.

[0041] like Figure 5 and Figure 6 As shown, the bottom end of the reciprocating screw 12 is fixedly connected with a second gear 16, one side of the second gear 16 is meshedly connected with a third gear 17, a second rotating shaft 18 is embedded inside the third gear 17, the outer wall of the second rotating shaft 18 is evenly provided with connecting blocks 19 in a ring array, the bottom end of the second rotating shaft 18 is fixedly installed with a first bevel gear 20, one side of the first bevel gear 20 is meshedly connected with a second bevel gear 21, and the second bevel gear 21 is fixedly installed on one end of the mounting roller 8.

[0042] When the reciprocating screw 12 rotates, it drives the second gear 16 to rotate, the rotation of the second gear 16 drives the rotation of the third gear 17, the rotation of the third gear 17 drives the rotation of the connecting block 19, the rotation of the connecting block 19 drives the rotation of the second rotating shaft 18, the rotation of the second rotating shaft 18 drives the rotation of the first bevel gear 20, the rotation of the first bevel gear 20 drives the rotation of the second bevel gear 21, the rotation of the second bevel gear 21 drives the rotation of the mounting roller 8, so that the mounting roller 8 inside the mounting base 6 rotates to reel in the oil absorbent cloth 7, and the oil absorbent cloth 7 inside the mounting top seat 5 is unwound, so as to ensure that the oil absorption operation is carried out continuously without frequent replacement of the oil absorbent cloth 7, thereby improving work efficiency.

[0043] The inner wall diameter of the third gear 17 is ten N times the inner wall diameter of the second gear 16, and N is a positive integer;

[0044] The speed of rolling up the oil-absorbing cloth 7 is reduced so that the oil-absorbing cloth 7 is in full contact with the oil film on the liquid surface.

[0045] like Figure 6 As shown, the connecting block 19 is slidably connected to the third gear 17 .

[0046] The third gear 17 drives the second rotating shaft 18 to rotate through the connecting block 19 during the rotation process, thereby transmitting the rotation and winding of the installation roller 8;

[0047] When the moving base 4 moves up and down, the connecting block 19 slides inside the third gear 17 .

[0051] The fan 24 is rotated by the built-in motor 10;

[0052] During sewage treatment, the fan 24 is driven to create a negative pressure inside the pipe 23, and external gas enters the pipe 23 and is eventually discharged into the sewage from the air outlet 26. The oil droplets adhere to highly dispersed microbubbles to increase buoyancy, thereby increasing the floating speed and improving the oil-water separation efficiency.

[0054] Prevent sewage backflow.

[0055] like Figure 5 As shown, the air outlet 26 is configured to be conical.

[0056] Optimize the gas dispersion effect. When the air flows out through the conical hole, the airflow will be compressed and accelerated to a certain extent due to the gradual contraction of the hole wall, which helps to disperse the air into smaller bubbles and increase the contact area between the bubbles and water, thereby improving the dissolution efficiency and diffusion effect of the gas in water.

The rotation of the reciprocating screw 12 drives the first gear 13 to rotate about the axis of the first rotating shaft 3. The first gear 13 rotates itself when it moves and meshes with the tooth block 14. The rotation of the first gear 13 drives the rotation of the reciprocating screw 12. The rotation of the reciprocating screw 12 drives the moving plate 11 to move up and down. The movement of the moving plate 11 drives the movement of the moving seat 4. The movement of the moving seat 4 drives the movement of the mounting top seat 5 and the mounting base 6, so that the oil absorbent cloth 7 moves up and down at the sewage surface, allowing the oil absorbent cloth 7 to fully absorb the oil stains.
