Description

Technical Field

[0001] This utility model relates to the field of oil-water separation technology, and more specifically, to an integrated oil-water separator. Background Technology

[0002] Industrial wastewater refers to wastewater containing various pollutants generated during industrial production processes. Its sources cover almost all industrial sectors, and its composition is complex and its hazards are significant. Specifically, it can be understood from three aspects: "source", "core pollutant" and "hazard". Examples include cutting fluid wastewater from machining and oily wastewater from metal surface treatment (electroplating, phosphating).

[0003] If wastewater is reused in production (such as cooling and cleaning), oil will adhere to the inner wall of the equipment pipes, resulting in reduced heat exchange efficiency and pipe blockage. If it enters a subsequent sewage treatment system (such as a biological treatment tank), the oil film will encapsulate microorganisms, destroying the biological treatment effect and causing the effluent to fail to meet standards. Therefore, an integrated oil-water separator is provided. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, this utility model provides an integrated oil-water separator, which aims to solve the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: an integrated oil-water separator, including a processing tank, on which a separation component is provided; The separation assembly includes an oil-collecting hood disposed on the top of the processing tank. The vertical cross-sectional shape of the oil-collecting hood is trapezoidal, and an oil-collecting cavity is provided at the top of the inner cavity of the oil-collecting hood. Upper oil drain pipes are embedded on both sides of the oil-collecting hood. The processing box has lower oil drain pipes embedded on both sides, and a central cylinder is provided inside the oil collection chamber.

[0006] Optionally, in a possible implementation, a connecting cylinder is bolted to the outside of the central cylinder. The connecting cylinder is embedded in the top of the oil-absorbing cover and snaps into it. A sealing cover is hinged to the middle of the connecting cylinder. A sealing gasket is fitted on the outside of the sealing cover. A vibration motor is installed at the bottom of the treatment box. A sealing cover is fitted on the outside of the vibration motor and extends to the bottom of the inner cavity of the treatment box. Drain valves are respectively installed at both ends of the vibration motor. A limiting frame is fitted on the outside of each drain valve. The limiting frame is bolted to the bottom of the inner cavity of the treatment box. Diversion bars are respectively installed at both ends of the central cylinder. Several oil-absorbing filter elements are embedded inside the central cylinder. The technical effects and advantages of this utility model are as follows: By utilizing the adsorption effect of the oil-absorbing filter element and the effect of the vibration motor to promote oil-water stratification, oil and water in oily wastewater can be separated efficiently. The separation effect is good, and the oil in the wastewater can be effectively removed, avoiding the adverse effects of oil on subsequent production equipment and sewage treatment system. Furthermore, the vibration generated by the vibrating motor is transmitted to the oily wastewater in the treatment tank, causing the oil and water to further separate. Due to its lower density, the oil gradually floats to the top. The upper layer of oil enters the oil-collecting chamber at the top of the oil-collecting hood. As the amount of oil in the oil-collecting chamber increases, it can be discharged through the upper oil drain ports on both sides of the oil-collecting hood. Some of the oil located in the lower layer of the treatment tank can be discharged through the lower oil drain ports on both sides of the treatment tank, ensuring the separation quality and effect.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] This embodiment discloses an integrated oil-water separator, which aims to solve the problems in the prior art of treating industrial oily wastewater, such as the decrease in heat exchange efficiency and pipe blockage caused by oil adhering to equipment pipes, and the damage to the biochemical effect and failure of effluent to meet standards when oil enters the biochemical treatment system. The specific settings are as follows.

[0015] The processing tank 1, as the main supporting component for oil-water separation, provides installation and working space for the internal components. The separation component is the core part for achieving oil-water separation, including an oil-collecting hood 2 located on top of the processing tank 1. The vertical cross-section of the oil-collecting hood 2 is trapezoidal, which facilitates oil collection and reduces oil dispersion. An oil-collecting chamber is provided at the top of the inner cavity of the oil-collecting hood 2, which is specifically used to collect the separated oil. Upper oil drain pipes 3 are embedded on both sides of the oil-collecting hood 2, and the upper oil drain pipes 3 are connected to the oil-collecting chamber. When the oil collected in the oil-collecting chamber reaches a certain amount, the oil can be discharged through the upper oil drain pipes 3.

[0016] The processing tank 1 has lower oil drain ports 4 embedded on both sides. The lower oil drain ports 4 are mainly used to discharge the oil separated in the lower part of the processing tank 1. Depending on the actual oil-water separation situation, they can be used in conjunction with the upper oil drain ports 3 to discharge oil from different locations, improving the comprehensiveness of oil discharge. A central cylinder 5 is set in the oil collection chamber. The central cylinder 5 plays a key role in filtering and guiding the flow during the oil-water separation process.

[0017] like Figure 4 As shown, flow dividers 6 are provided at both ends of the central cylinder 5. The flow dividers 6 can divert the oil-water mixture entering the central cylinder 5, allowing the oil-water mixture to enter the interior of the central cylinder 5 more evenly and avoiding excessive local flow that could affect the separation effect. Several oil-absorbing filter elements 7 are embedded inside the central cylinder 5. The oil-absorbing filter elements 7 are made of materials with high oil absorption performance, which can effectively adsorb oil in the oil-water mixture, further improving the efficiency and effect of oil-water separation. Moreover, the arrangement of several oil-absorbing filter elements 7 can increase the oil absorption area and enhance the oil absorption capacity.

[0018] A connecting cylinder 8 is bolted to the outside of the central cylinder 5. This bolted connection facilitates the installation, disassembly, and maintenance of the connecting cylinder 8 and the central cylinder 5. The connecting cylinder 8 is embedded in the top of the oil-absorbing cover 2 and engages with it. This engagement structure ensures the stability of the connection between the connecting cylinder 8 and the oil-absorbing cover 2, and also facilitates the later disassembly, maintenance, or replacement of both the connecting cylinder 8 and the central cylinder 5. A sealing cover 9 is hinged to the middle of the connecting cylinder 8, and a sealing gasket is fitted on the outside of the sealing cover 9. The sealing cover 9 seals the top opening of the connecting cylinder 8, preventing external impurities from entering the equipment during oil-water separation and avoiding internal oil or water leakage. The sealing gasket further enhances the sealing effect of the sealing cover 9, ensuring the equipment's airtightness.

[0019] like Figure 3 As shown, a vibration motor 10 is installed at the bottom of the processing tank 1. A sealing cover is provided on the outer side of the vibration motor 10, and the sealing cover extends to the bottom of the inner cavity of the processing tank 1. When the vibration motor 10 is working, it can generate vibration, which can be transmitted to the oil-water mixture inside the processing tank 1, promoting better stratification of oil and water, accelerating the oil-water separation speed, and improving the separation efficiency. The sealing cover can protect the vibration motor 10, preventing water or oil from the processing tank 1 from entering the vibration motor 10 and affecting the normal operation and service life of the vibration motor 10.

[0020] Each end of the vibratory motor 10 is equipped with a drain valve 11, which is connected to the inside of the treatment tank 1. After the oil-water separation is completed, the water in the treatment tank 1 can be discharged through the drain valve 11. Each drain valve 11 is fitted with a limiting frame 12 on its outer side. The limiting frame 12 is installed at the bottom of the inner cavity of the treatment tank 1 by bolts. The limiting frame 12 can fix and limit the drain valve 11, preventing the drain valve 11 from shifting or loosening due to vibration or other factors during equipment operation, and ensuring the stable operation of the drain valve 11. The specific working principle is as follows: First, the industrial oily wastewater is introduced into the treatment tank 1. During its flow within the treatment tank 1, the oily wastewater passes through the diversion barriers 6 at both ends of the central cylinder 5, which evenly distribute the oily wastewater into the interior of the central cylinder 5. The oily wastewater entering the central cylinder 5 comes into full contact with the internal oil-absorbing filter element 7, which adsorbs the oil in the wastewater, achieving preliminary oil-water separation.

[0021] Simultaneously, the vibration motor 10 at the bottom of the treatment tank 1 is activated. The vibration generated by the vibration motor 10 is transmitted to the oily wastewater in the treatment tank 1, causing the oil and water to further separate. Due to its lower density, the oil will gradually float to the top. The upper layer of oil will enter the oil collection chamber at the top of the oil collection hood 2. As the amount of oil in the oil collection chamber increases, the oil can be discharged through the upper oil drain pipes 3 on both sides of the oil collection hood 2; some of the oil located in the lower layer of the treatment tank 1 can be discharged through the lower oil drain pipes 4 on both sides of the treatment tank 1.

[0022] Once the oil-water separation is complete, open the drain valves 11 at both ends of the vibrating motor 10. The separated water in the treatment tank 1 will be discharged through the drain valves 11, thus completing the entire oil-water separation process.

[0023] When the equipment needs maintenance or replacement of the oil suction filter element 7, the central cylinder 5 can be removed from the oil collection cover 2 to replace the oil suction filter element 7 or perform internal maintenance on the equipment, which is convenient.

[0024] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
