The input end of the oil pump 121 is connected to the oil collecting frame 105 through the oil suction pipe 122. After the sewage is transported to the inner tank 102, the inner tank 102 is driven to rotate inside the outer tank 101 through the driving mechanism provided on the outer tank 101. During the rotation, the electrode ring assembly 116 supplies power to the electromagnetic stirring paddle 115, and the electromagnetic stirring paddle 115 is used to absorb iron filings in the water. Due to the different densities of water and oil, the centrifugal force applied to the inner tank 102 when it rotates is different, and the grease will gather at the center of the water surface. The hydraulic cylinder 103 is started to lower the oil collecting frame 105 to the grease, and the grease enters the interior of the oil collecting frame 105 through the hydrophobic and oleophilic filter membrane 120. The oil discharge pump is started to discharge it through the oil suction pipe 122. The purified water and iron filings are discharged from the sewage pipe 117 in turn, completing the separation of iron filings and grease in the wastewater.

[0026] The mounting ring 109 is detachably connected to the outer tank 101 and sleeved on the outside of the outer tank 101. The mounting ring 109 is provided with the mounting seat 110. The top of the mounting seat 110 is provided with the rotating disk 111. The servo motor 106 is provided inside the mounting seat 110. The output end of the servo motor 106 is provided with the output shaft 107. The output gear 108 is provided at the end of the output shaft 107 away from the servo motor 106.

Since the output gear 108 is meshed with the driven tooth portion 123, the rotating disk 111 is driven to rotate on the mounting seat 110, and then the oil collecting frame 105 is rotated to the outside of the outer tank 101. Then, start the hydraulic cylinder 103 to drive the oil collecting frame 105 to descend, so as to facilitate the replacement of the hydrophobic and oleophilic filter membrane 120 on the oil collecting frame 105. With the above structure, the operation is more convenient when replacing the hydrophobic and oleophilic filter membrane 120.

[0028] At the same time, fixed wing rings 125 are provided on both sides of the mounting ring 109, and the two fixed wing rings 125 are detachably connected to the outer wall of the outer tank 101. After the mounting ring 109 is sleeved on the outside of the outer tank 101, the fixed wing rings 125 are fixed to the outer wall of the outer tank 101 with screws, thereby completing the installation of the mounting ring 109.

[0029] In addition, a heat dissipation groove 126 is provided on the outer wall of the mounting base 110, and the heat dissipation groove 126 corresponds to the servo motor 106. Through the setting of the heat dissipation groove 126, the interior of the mounting base 110 is kept in circulation with the outside air, so that the flowing air takes away the heat generated by the servo motor 106 during operation, thereby dissipating the heat of the servo motor 106.

[0030] When a wastewater treatment tank of the present embodiment is used, after the sewage is transported into the inner tank 102, the inner tank 102 is driven to rotate inside the outer tank 101 through the driving mechanism provided on the outer tank 101. During the rotation, the electrode ring assembly 116 supplies power to the electromagnetic stirring paddle 115, and the electromagnetic stirring paddle 115 is used to absorb iron filings in the water. Since the densities of water and oil are different, the centrifugal forces applied to the inner tank 102 when it rotates are different, and the grease will gather at the center of the water surface. The hydraulic cylinder 103 is started to lower the oil collecting frame 105 to the grease, and the grease enters the interior of the oil collecting frame 105 through the hydrophobic and oleophilic filter membrane 120. The oil discharge pump is started to discharge the wastewater through the oil suction pipe 122, and the purified water and iron filings are discharged from the drain pipe 117 in turn, thereby completing the iron filings and Grease separation, and when it is necessary to replace the hydrophobic and oleophilic filter membrane 120 set on the oil collecting frame 105, start the hydraulic cylinder 103, so that the oil collecting frame 105 is away from the top of the inner tank 102, start the servo motor 106, and drive the output gear 108 to rotate through the output shaft 107. Since the output gear 108 is engaged with the driven gear portion 123, the rotating disk 111 is driven to rotate on the mounting seat 110, and then the oil collecting frame 105 is rotated to the outside of the outer tank 101, and then the hydraulic cylinder 103 is started to drive the oil collecting frame 105 to descend, so as to facilitate the replacement of the hydrophobic and oleophilic filter membrane 120 on the oil collecting frame 105. With the above structure, the operation is more convenient when the hydrophobic and oleophilic filter membrane 120 is replaced.

Through the provision of the air-cooling blades 202, the circulation speed between the inside of the mounting base 110 and the outside air is made faster, so that the heat dissipation effect of the servo motor 106 is better.

[0035] Among them, fixing blocks 203 are provided on both sides of one end of the mounting shell 201 close to the mounting seat 110, and the fixing blocks 203 are detachably connected to the outer wall of the mounting seat 110. After the mounting shell 201 is covered on the outside of part of the heat dissipation slot 126, the fixing blocks 203 are fixed to the outer wall of the mounting shell 201 by screws, thereby completing the installation of the mounting shell 201.

[0036] When using a wastewater treatment tank of the present embodiment, after the mounting shell 201 is covered on the outside of part of the heat dissipation slot 126, the fixing block 203 is fixed to the outer wall of the mounting shell 201 by screws, thereby completing the installation of the mounting shell 201, and the air-cooling fan blades 202 are installed inside the mounting shell 201. Through the setting of the air-cooling fan blades 202, the circulation speed between the inside of the mounting seat 110 and the outside air is faster, so that the heat dissipation effect of the servo motor 106 is better.
