[0002] Wastewater treatment refers to the purification of water bodies containing harmful substances such as domestic sewage and industrial wastewater to meet emission standards or recycling requirements.

[0003] In many cases, sewage contains grease, oil and other solid particles. If these pollutants are discharged directly into the environment without treatment, it will cause serious pollution to the environment and may cause harm to human health. Therefore, oil-water separation equipment is usually required in the treatment of oily sewage.

[0004] In the existing oil-water separation equipment in winter or in a low temperature environment, the grease will solidify into a solid. The solid grease will gradually accumulate on the filter, causing the filter inside the oil-water separation equipment to be blocked, thus affecting the normal oil-water separation work of the separation equipment. Therefore, in view of the above problem, an oil-water separation equipment for sewage treatment is proposed. Utility Model Content

During operation, when the filter screen 101 is clogged, the heating tube 110 can be started first. After the heating tube 110 is running, the oil and water inside the equipment box 1 can be heated, thereby increasing the temperature of the oil, reducing the viscosity of the oil, and reducing the adhesion between the oil and water. Then the servo motor 108 is operated. After the servo motor 108 is operated, the forward rotation will drive the worm 109 to rotate. The rotation of the worm 109 will drive the meshing worm wheel 107 to rotate. The rotation of the worm wheel 107 can drive the screw rod 102 and the pulley 105 on the rear side to rotate. The screw rod 102 and the pulley 105 on the rear side are rotated. When 105 rotates, the front screw rod 102 and the pulley 105 can be driven to rotate simultaneously through the belt 106. When the screw rod 102 rotates simultaneously, the threaded moving block 103 can be driven to move downward smoothly. The moving block 103 can also drive the cleaning member 104 to move downward when it moves downward. When the servo motor 108 is reversed, the cleaning member 104 can be moved upward. When the cleaning member 104 moves, the oil stains adhered to the surface of the filter screen 101 can be cleaned to prevent the oil stains from clogging the holes of the filter screen 101 and affecting the normal operation of the oil-water separation equipment.

[0026] Further, such as Figure 1 - Figure 4As shown, the oil suction mechanism includes an oil suction pump 201, an oil suction pipe 202 and an oil storage barrel 203. The oil suction pump 201 is fixedly installed on the front side of the equipment box 1, one end of the oil suction pipe 202 is connected to the front side of the equipment box 1, and the other end of the oil suction pipe 202 is connected to the oil suction pump 201. The oil storage barrel 203 is arranged on the front side of the equipment box 1, and the oil storage barrel 203 is connected to the oil suction pump 201 through a pipeline. During operation, after oil-water separation, the oil will float on the water surface, and then the oil suction pump 201 can be operated. After the oil suction pump 201 is operated, the oil floating inside the equipment box 1 can be sucked into the connected oil storage barrel 203 through the oil suction pipe 202, thereby effectively and quickly extracting the oil from the separation equipment box 1, improving the processing efficiency, reducing the need for manual intervention, and saving time and labor costs.

[0027] Further, such as Figure 3 and Figure 4 As shown, the front and rear sides of the cleaning member 104 are fixedly connected with a slider 301, and the front and rear sides of the inner wall of the equipment box 1 are provided with a slide groove 302 used in conjunction with the slider 301. During operation, when the cleaning member 104 moves up and down, the cleaning member 104 will drive the slider 301 to slide inside the slide groove 302, so as to avoid displacement and shaking of the cleaning member 104 due to lack of limit when moving, and affect the cleaning effect of the filter 101, thereby playing an auxiliary limit role for the cleaning member 104.

[0028] Further, such as Figure 1 and Figure 2 As shown, the surface of the worm 109 is sleeved with a support member 4, and the support member 4 is fixedly connected to the top of the equipment box 1. During operation, when the worm 109 rotates, the end of the worm 109 can be auxiliary supported by the support member 4 to prevent the end of the worm 109 from being disconnected from the worm wheel 107 due to lack of support when rotating, which will affect the normal operation of the cleaning mechanism.

[0029] Further, such as Figure 1 As shown, a reinforcement plate 5 is fixedly connected to the front side of the equipment box 1, and the reinforcement plate 5 is fixedly connected to the oil suction pump 201. During operation, the oil suction pump 201 can be reinforced and supported to prevent the oil suction pump 201 from vibrating during operation and causing the connection to become loose, thereby increasing the connection stability of the oil suction pump 201.

[0030] Further, such as Figure 3 and Figure 4 As shown, the top end of the screw rod 102 is respectively connected to a bracket 6 by a bearing, and the bracket 6 is fixedly connected to the top of the equipment box 1. During operation, under the stable support of the bracket 6, the screw rod 102 is convenient to rotate stably, and the screw rod 102 is prevented from being deviated due to lack of fixation during rotation, thereby playing a role of stable support for the screw rod 102.

[0031] Further, such as Figure 1 and Figure 2 As shown, a limiting ring 7 is sleeved on the surface of the worm 109, and the limiting ring 7 is located on one side of the support 4. During operation, when the worm 109 rotates, the limiting ring 7 can be used to auxiliary limit the worm 109 to prevent the worm 109 from escaping from the inside of the support 4 during rotation.

[0032] Working principle: When the oil-water separation is performed, when the filter 101 is blocked, the heating tube 110 can be started first. After the heating tube 110 is running, the oil and water inside the equipment box 1 will be heated, thereby increasing the temperature of the oil, reducing the viscosity of the oil, and reducing the adhesion between the oil and water. Then the servo motor 108 is operated. After the servo motor 108 is operated, the forward rotation will drive the worm 109 to rotate, and the rotation of the worm 109 will drive the meshing worm wheel 107 to rotate. The rotation of the worm wheel 107 can drive the rear side screw rod 102 and the pulley 105 to rotate. The rotation of the rear side screw rod 102 and the pulley 105 can drive the front side screw rod 102 and the pulley 105 to rotate at the same time through the belt 106. When the screw rod 102 rotates at the same time, it can drive the threaded moving block 103 Move downward smoothly, and the moving block 103 can drive the cleaning part 104 to move downward at the same time. When the servo motor 108 is reversed, the cleaning part 104 can move upward. The cleaning part 104 can clean the oil stains adhered to the surface of the filter screen 101 when it moves, so as to prevent the oil stains from clogging the holes of the filter screen 101 and affecting the normal operation of the oil-water separation equipment. After the oil and water are separated, the oil stains will float on the water surface, and then the oil suction pump 201 can be operated. After the oil suction pump 201 is running, the oil stains floating inside the equipment box 1 can be sucked into the connected oil storage barrel 203 through the oil suction pipe 202, thereby effectively and quickly extracting the oil stains from the separation equipment box 1, thereby improving the processing efficiency, reducing the need for manual intervention, and saving time and labor costs.
