Description

Technical Field

[0001] This utility model relates to a technical field, specifically to a filtration mechanism for oily wastewater pipelines. Background Technology

[0002] Oily wastewater refers to wastewater containing oily substances generated during industrial production, urban sewage treatment, agricultural irrigation, and other processes. With social development and progress, people's living standards are getting higher and higher, and with people's pursuit of quality of life, the amount of wastewater generated by people is also increasing, and a large amount of wastewater contains oil stains. In order to avoid the pollution of the environment caused by the direct discharge of oily wastewater through pipelines, it is necessary to install filtration devices on the pipelines to treat the oily wastewater.

[0003] In existing technologies, when treating oily wastewater, the wastewater is piped into a sedimentation tank in a filtration system for sedimentation. After the oil and water naturally separate, the top oil and water are discharged separately. This treatment method cannot completely separate the oil from the wastewater. Discharging even a small amount of oily wastewater will cause serious harm to the environment. Furthermore, the waste oil that is not completely separated from the water cannot be reused, which is a waste of non-renewable resources. Utility Model Content

[0004] In view of the above-mentioned defects or deficiencies in the prior art, it is desirable to provide a filtration mechanism for oily wastewater pipelines.

[0005] According to the technical solution provided in the embodiments of this application, a filtration mechanism for an oily wastewater pipeline is provided. An inlet is installed at the upper left end of the treatment tank, and an outlet pipe and an oil drain pipe are installed at the lower right end of the treatment tank. The treatment tank is divided into a first processing area and a second processing area on its left and right sides. A servo motor is installed on the upper right side of the treatment tank. A coarse sieve plate and a fine sieve plate are sequentially installed on the upper side of the first processing area. A set of evenly distributed ultrasonic transducers are installed in the middle of the front and rear walls of the first processing area. A sand and gravel filter plate is laid at the lower end of the first processing area. A water pump is embedded in the interlayer between the first and second processing areas. The inlet is connected to the first processing area. The outer end is connected to the wastewater pipeline by a pipe valve. The coarse screen plate is placed on top of the fine screen plate. Both the coarse and fine screen plates are placed with the left side higher than the right side. The sand and gravel filter plate is placed below the ultrasonic transducer. A guide pipe is installed at the lower end of the water pump. A pipe is provided on the right side of the water pump and extends into the second processing area. The other end of the guide pipe extends in the opposite direction to the inner bottom end of the first processing area and a filter head is installed. A stirring rod is vertically suspended in the middle of the second processing area. A separation area is installed on the lower side of the second processing area. A reagent box is installed on the right side of the top of the second processing area. The upper end of the stirring rod is connected to the servo motor through a coupling. Multiple evenly distributed blades are staggered on the arm of the stirring rod.

[0006] Furthermore, the medicine box has an opening at the bottom.

[0007] Furthermore, the separation zone is connected to the second processing zone via pipes and valves. A high-density oil filter membrane is laid in the middle of the separation zone, and water electrolyzers are installed at both the front and rear inner ends of the separation zone.

[0008] Furthermore, one end of both the oil drain pipe and the water outlet pipe extends into the separation zone, while the other end of both extends in the opposite direction to the right outer side of the treatment tank.

[0009] Furthermore, the oil drain pipe is placed on the upper right side of the high-density oil filter membrane, and a matching valve is installed on the oil drain pipe. The water outlet pipe is placed on the lower right side of the high-density oil filter membrane.

[0010] Furthermore, the water electrolyzer is placed below the high-density oil filter membrane.

[0011] In summary, the beneficial effects of this application are as follows:

[0012] First, by setting up a first processing zone, a second processing zone, and a separation zone, oily wastewater can undergo multi-stage filtration and separation treatment, resulting in good separation of wastewater and oil. Wastewater and waste oil can be discharged separately, waste oil can be recycled and reused, and wastewater meets discharge standards, saving non-renewable resources and protecting the environment. The treatment tank is connected to the wastewater pipeline with a valve at the external end of the inlet, making installation, operation, and use simple and convenient, further improving the treatment efficiency of oily wastewater.

[0020] like Figures 1-3 As shown, a filtration mechanism for an oily wastewater pipeline includes an inlet 3 installed at the upper left side of a treatment tank 1, and an outlet pipe 18 and an oil drain pipe 16 installed at the lower right side of the treatment tank 1. The treatment tank 1 is divided into a first processing area 2 and a second processing area 10 on the left and right sides. A servo motor 11 is installed on the upper right side of the treatment tank 1. A coarse sieve plate 4 and a fine sieve plate 5 are sequentially installed on the upper side of the first processing area 2, with the coarse sieve plate 4 positioned above the fine sieve plate 5. Both the coarse sieve plate 4 and the fine sieve plate 5 are positioned with the left side higher than the right side. A set of evenly distributed ultrasonic transducers 6 are installed in the middle of the front and rear walls of the first processing area 2. A sand and gravel filter plate 7 is laid at the lower end of the first processing area 2. A water pump 9 is embedded in the interlayer between the first processing area 2 and the second processing area 2. A guide pipe 9 is installed at the lower end of the water pump 8. A pipe is provided on the right side of the water pump 8 and extends into the second processing area 10. The other end extends in the opposite direction to the inner bottom of the first processing zone 2 and is equipped with a filter head 801. A stirring rod 12 is vertically suspended in the middle of the second processing zone 10. A separation zone 14 is installed on the lower side of the second processing zone 10. A reagent box 13 is installed on the right side of the top of the second processing zone 10. Multiple evenly distributed blades 1201 are staggered on the arm of the stirring rod 12. The separation zone 14 is connected to the second processing zone 10 through a pipe valve. A high-density oil filter membrane 15 is laid in the middle of the separation zone 14. Water electrolyzers 17 are installed at both the front and rear inner ends of the separation zone 14. One end of the oil drain pipe 16 and the water outlet pipe 18 extends into the separation zone 14. The oily wastewater can be filtered and separated in multiple stages. The separation effect of wastewater and oil is good. Wastewater and waste oil can be discharged separately. Waste oil can be recycled and reused. Wastewater meets the discharge standards, saving non-renewable resources and protecting the environment.

[0021] Furthermore, the treatment box 1 is connected to the wastewater pipeline via a pipe valve through the outer end of the inlet 2, which makes installation and operation simple and convenient, further improving the treatment efficiency of oily wastewater.

[0022] Furthermore, both the coarse sieve plate 4 and the fine sieve plate 5 are placed with the left side higher than the right side, which allows impurities to be placed upside down at the bottom left for unified collection and convenient discharge.

[0023] The working principle is as follows:

[0024] like Figures 1-3As shown, oily wastewater enters the first processing zone 2 of the treatment tank through the wastewater pipe via the inlet 3. The coarse sieve plate 4 and the fine sieve plate 5 can filter out impurities in the oily wastewater. The ultrasonic transducer 6 can accelerate the degradation and oxidation reaction of organic matter in the oily wastewater. When used in conjunction with the sand and gravel filter plate 7, it can perform the initial separation treatment of the oily wastewater. Then, the initially separated oily wastewater is transported to the second processing zone 10 via the water pump 9 and the guide pipe 8. The reagent box 13 contains demulsifier. The servo motor 11 drives the stirring rod 12 and the blade 1201 to rotate around the axis, so as to mix the demulsifier with the oily wastewater evenly, which is conducive to the complete separation of the oily wastewater. The waste oil and wastewater flow into the separation zone 14 in sequence. The separated waste oil is discharged through the oil drain pipe 16 under the barrier of the high-density oil filter membrane 15. The wastewater enters the bottom of the separation zone 14. The water electrolyzer decomposes the wastewater, electrolyzes hydrogen and oxygen, and finally discharges it through the outlet 18.

[0025] The above description is merely a preferred embodiment of this application and an explanation of the technical principles and solutions employed. Furthermore, the scope of the utility model involved in this application is not limited to the specific combination of the above-described technical features, but should also cover other technical solutions formed by any combination of the above-described technical features or their equivalents without departing from the inventive concept.
