Description

Technical Field

[0001] This invention belongs to the field of wastewater treatment technology, specifically an energy-saving wastewater treatment device and method. Background Technology

[0002] Wastewater treatment refers to the process of purifying wastewater to meet the water quality requirements for discharge into a water body or for reuse. This process is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscape, medical care, and catering, and is increasingly becoming a part of the public's daily life.

[0003] During wastewater treatment, a certain proportion of flocculant is added to the wastewater, and then the suspended particles are separated from the wastewater by settling. Since the wastewater contains a certain amount of oil, these oil substances float to the surface of the water and form an oil film because their density is less than that of water. This oil film not only interferes with the normal operation of wastewater treatment facilities and reduces treatment efficiency, but may also cause harm to the environment and human health. Summary of the Invention

[0004] The purpose of this invention is to provide an energy-saving wastewater treatment device and method to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an energy-saving sewage treatment device, comprising a treatment device body, wherein a drain pipe is fixedly installed on the side wall of the treatment device body, and an oil scraping assembly is provided inside the treatment device body;

[0006] The oil scraping assembly includes a first rotating shaft disposed inside the main body of the processing device. A motor is fixedly installed at the bottom end of the first rotating shaft, and a movable seat is installed at the top end of the first rotating shaft via a movable component. A mounting top and a mounting base are fixedly installed on the side wall of the movable seat. Mounting rollers are rotatably connected inside both the mounting top and the mounting base. An oil-absorbing cloth is installed on the outer wall of the mounting rollers, and an air-enhancing component is disposed inside the mounting base.

[0007] As a further technical solution of the present invention, one end of the mounting top seat is provided with a mounting block, which is embedded in the outer wall of the mounting roller and threadedly connected to the mounting roller.

[0008] As a further technical solution of the present invention, the moving component includes a moving plate fixedly installed on the top of the moving seat, a reciprocating screw threadedly connected to the inside of the moving plate, the reciprocating screw being rotatably installed inside the first rotating shaft, a first gear fixedly connected to the top of the reciprocating screw, a toothed block meshing with one side of the first gear, the toothed block being fixedly installed inside the bracket, and the bracket being fixedly installed on the top of the main body of the processing device.

[0009] As a further technical solution of the present invention, a second gear is fixedly connected to the bottom end of the reciprocating screw, a third gear is meshed with one side of the second gear, a second rotating shaft is embedded inside the third gear, connecting blocks are evenly arranged in a ring array on the outer wall of the second rotating shaft, a first bevel gear is fixedly installed at the bottom end of the second rotating shaft, a second bevel gear is meshed with one side of the first bevel gear, and the second bevel gear is fixedly installed at one end of the mounting roller.

[0010] As a further technical solution of the present invention, the connecting block is slidably connected to the third gear.

[0011] As a further technical solution of the present invention, a connecting plate is rotatably mounted on the outer wall of the second rotating shaft, and the connecting plate is fixedly mounted on one side of the movable seat.

[0012] As a further technical solution of the present invention, the air-enhancing component includes a pipe disposed inside the mounting base, the pipe passing through the interior of the mounting base and extending to the interior of the movable seat, a fan being installed inside the movable seat, and air outlets being evenly distributed inside the mounting base.

[0013] As a further technical solution of the present invention, a one-way valve is installed on the outer wall of the pipe.

[0014] As a further technical solution of the present invention, the air outlet is configured as a cone shape.

[0015] A method for an energy-saving wastewater treatment device includes the following steps:

[0016] S1: In wastewater treatment, wastewater and flocculant are first added into the main body of the treatment device, and then it is allowed to stand. After standing, an oil film floats on the surface of the wastewater. Then, the fan and motor are started. When the fan is driven, the inside of the pipe is under negative pressure, and external gas enters the pipe and is finally discharged from the gas outlet into the wastewater to accelerate oil-water separation.

[0017] S2: When driven by the motor, the first rotating shaft rotates slowly. The rotation of the first rotating shaft drives the moving seat to rotate, and the rotation of the moving seat drives the rotating mounting top, mounting base, and oil-absorbing cloth to rotate, causing the oil-absorbing cloth to move at the surface of the sewage and absorb the oil on the surface of the sewage.

[0018] S3: When the first rotating shaft rotates, it drives the reciprocating screw to rotate below the bracket. The rotation of the reciprocating screw drives the first gear to rotate around the axis of the first rotating shaft. When the first gear moves and meshes with the gear 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, thereby causing the oil-absorbing cloth to move up and down at the surface of the sewage, allowing the oil-absorbing cloth to fully absorb the oil.

[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 mounting roller, causing the mounting roller inside the mounting base to rotate and roll up the oil-absorbing cloth. The oil-absorbing cloth inside the mounting top seat is unrolled, allowing for continuous operation.

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

[0021] 1. This invention, through the setting of the oil scraping component, firstly adds sewage and flocculant into the main body of the treatment device during sewage treatment, and then lets it stand. After standing, an oil film floats on the surface of the sewage. Then, the first rotating shaft is driven by the 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 rotating mounting top, mounting base and oil-absorbing cloth to rotate, so that the oil-absorbing cloth moves at the sewage surface and absorbs the oil on the sewage surface, thereby improving the sewage treatment efficiency.

[0022] 2. This invention, through the arrangement of the moving component, allows the first rotating shaft to drive the reciprocating screw to rotate below the bracket during its rotation. The rotation of the reciprocating screw drives the first gear to rotate around the axis of the first rotating shaft. When the first gear moves and meshes with the gear block, it rotates itself. The rotation of the first gear drives the rotation of the reciprocating screw, which in turn drives the moving plate to move up and down. The movement of the moving plate drives the movement of the moving seat, which in turn drives the movement of the mounting top and mounting base. This causes the oil-absorbing cloth to move up and down at the surface of the sewage, allowing the oil-absorbing cloth to fully absorb the oil, thereby increasing the oil absorption area and time, and improving the oil absorption efficiency.

[0023] 3. By setting up an air-enhancing component, the present invention creates a negative pressure inside the pipe during sewage treatment through a fan drive, allowing external gas to enter the pipe and eventually be discharged into the sewage from the air outlet. The oil droplets adhere to the highly dispersed microbubbles, increasing buoyancy and thus increasing the floating speed, thereby improving the oil-water separation efficiency.

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] like Figures 1 to 7 As shown in the embodiment of the present invention, an energy-saving sewage treatment device includes a treatment device body 1, a drain pipe 2 is fixedly installed on the side wall of the treatment device body 1, and an oil scraping assembly is provided inside the treatment device body 1.

[0034] The oil scraping assembly includes a first rotating shaft 3 located inside the main body 1 of the processing device. A motor 10 is fixedly installed at the bottom end of the first rotating shaft 3. A movable seat 4 is installed at the top end of the first rotating shaft 3 via a movable assembly. A mounting top seat 5 and a mounting base 6 are fixedly installed on the side wall of the movable seat 4. Mounting rollers 8 are rotatably connected inside both the mounting top seat 5 and the mounting base 6. An oil-absorbing cloth 7 is installed on the outer wall of the mounting rollers 8. An air-enhancing assembly is installed inside the mounting base 6.

[0035] The sewage level inside the main body 1 of the treatment device should be below the mounting base 5;

[0036] In wastewater treatment, wastewater and flocculant are first added into the main body 1 of the treatment device, and then it is allowed to stand. After standing, an oil film floats on the surface of the wastewater. Then, the first rotating shaft 3 is driven by the motor 10 to rotate slowly. The rotation of the first rotating shaft 3 drives the moving seat 4 to rotate. The rotation of the moving seat 4 drives the mounting top seat 5, the mounting base 6 and the oil-absorbing cloth 7 to rotate, so that the oil-absorbing cloth 7 moves at the surface of the wastewater and absorbs the oil on the surface of the wastewater, thereby improving the wastewater treatment efficiency.

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

[0038] Remove the oil-absorbing cloth 7 from the outer wall of the mounting roller 8 by rotating the mounting block 9.

[0039] like Figure 5 As shown, the moving assembly includes a moving plate 11 fixedly installed on the top of the moving base 4. A reciprocating screw 12 is threadedly connected inside the moving plate 11. The reciprocating screw 12 is rotatably installed inside the first rotating shaft 3. A first gear 13 is fixedly connected to the top of the reciprocating screw 12. A tooth block 14 is meshed on one side of the first gear 13. The tooth block 14 is fixedly installed inside the bracket 15. The bracket 15 is fixedly installed on the top of the main body 1 of the processing device.

[0040] When the first rotating shaft 3 rotates, it drives the reciprocating screw 12 to rotate below the bracket 15. The rotation of the reciprocating screw 12 drives the first gear 13 to rotate around the axis of the first rotating shaft 3. When the first gear 13 moves and meshes with the gear block 14, it rotates itself. 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, thereby causing the oil-absorbing cloth 7 to move up and down at the surface of the sewage, allowing the oil-absorbing cloth 7 to fully absorb the oil, thereby increasing the oil absorption area and time, and improving the oil absorption efficiency.

[0041] like Figure 5 and Figure 6 As shown, a second gear 16 is fixedly connected to the bottom end of the reciprocating screw 12, a third gear 17 is meshed with one side of the second gear 16, a second rotating shaft 18 is embedded inside the third gear 17, connecting blocks 19 are evenly arranged in a ring array on the outer wall of the second rotating shaft 18, a first bevel gear 20 is fixedly installed at the bottom end of the second rotating shaft 18, a second bevel gear 21 is meshed with one side of the first bevel gear 20, and the second bevel gear 21 is fixedly installed at 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, causing the mounting roller 8 inside the mounting base 6 to rotate and roll up the oil-absorbing cloth 7. The oil-absorbing cloth 7 inside the mounting top seat 5 is unrolled, ensuring that the oil absorption operation can be carried out continuously without frequent replacement of the oil-absorbing cloth 7, thereby improving work efficiency.

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

[0044] Reduce the speed of winding the oil-absorbing cloth 7 so that the oil-absorbing cloth 7 can fully contact 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] During the rotation of the third gear 17, the second rotating shaft 18 is driven to rotate through the connecting block 19, thereby transmitting the rotation to the mounting roller 8 for winding.

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

[0048] like Figure 6 and Figure 7 As shown, a connecting plate 22 is rotatably mounted on the outer wall of the second rotating shaft 18, and the connecting plate 22 is fixedly mounted on one side of the movable seat 4.

[0049] When the movable seat 4 moves up and down on one side of the first rotating shaft 3, it drives the second rotating shaft 18 to move up and down through the connecting plate 22.

[0050] like Figure 5 and Figure 6As shown, the air-enhancing component includes a pipe 23 disposed inside the mounting base 6. The pipe 23 passes through the interior of the mounting base 6 and extends into the interior of the movable seat 4. A fan 24 is installed inside the movable seat 4. Air outlets 26 are evenly distributed inside the mounting base 6.

[0051] Fan 24 rotates via built-in motor 10;

[0052] During wastewater treatment, the fan 24 drives the pipe 23 to create a negative pressure inside, allowing external gas to enter the pipe 23 and eventually be discharged into the wastewater from the outlet 26. The oil droplets adhere to the highly dispersed microbubbles, increasing buoyancy and thus increasing the floating speed, thereby improving the oil-water separation efficiency.

[0053] like Figure 5 and Figure 6 As shown, a one-way valve 25 is installed on the outer wall of pipe 23.

[0054] To prevent sewage backflow.

[0055] like Figure 5 As shown, the air outlet 26 is set in a cone shape.

[0056] To optimize gas dispersion, when air flows out through the conical hole, the airflow is compressed and accelerated due to the gradual contraction of the hole wall. This helps to disperse the air into finer bubbles and increase the contact area between the bubbles and water, thereby improving the dissolution efficiency and diffusion effect of the gas in water.

[0057] A method for an energy-saving wastewater treatment device includes the following steps:

[0058] S1: In the process of sewage treatment, sewage and flocculant are first put into the main body 1 of the treatment device, and then it is allowed to stand. After standing, an oil film floats on the surface of the sewage. Then, the fan 24 and motor 10 are started. When the fan 24 is driven, the inside of the pipe 23 is under negative pressure, and the external gas enters the pipe 23 and is finally discharged from the gas outlet 26 into the sewage to accelerate the oil-water separation.

[0059] S2: When driven by motor 10, the first rotating shaft 3 rotates slowly. The rotation of the first rotating shaft 3 drives the moving seat 4 to rotate. The rotation of the moving seat 4 drives the rotating mounting top seat 5, mounting base 6, and oil-absorbing cloth 7 to rotate, causing the oil-absorbing cloth 7 to move at the surface of the sewage and absorb the oil on the surface of the sewage.

[0060] S3: When the first rotating shaft 3 rotates, it drives the reciprocating screw 12 to rotate below the bracket 15. The rotation of the reciprocating screw 12 drives the first gear 13 to rotate around the axis of the first rotating shaft 3. When the first gear 13 moves and meshes with the gear block 14, it rotates itself. 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, thereby causing the oil-absorbing cloth 7 to move up and down at the surface of the sewage, so that the oil-absorbing cloth 7 can fully absorb the oil.

[0061] S4: 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, causing the mounting roller 8 inside the mounting base 6 to rotate and wind up the oil-absorbing cloth 7. The oil-absorbing cloth 7 inside the mounting top seat 5 is unwound, allowing for continuous operation.

[0062] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
