Abstract
Description
Technical Field
[0001] This utility model relates to the field of oil-water separation technology, and in particular to an oil-water separator that improves the separation effect. Background Technology
[0002] Oily wastewater originates from the catering industry, oil extraction and processing, petrochemical industry, metallurgy and machinery industry, and maritime transportation industry. According to statistics, at least 5 million to 10 million tons of oil enter water bodies worldwide every year through various channels. This not only causes water pollution but also wastes oil resources. To address this problem, an oil-water separator with improved separation efficiency is used. Traditional oil-water separators use a separation tank and filter plates to achieve oil-water separation, mainly using sedimentation to separate oil and water. Then, the grease inside the separation tank is manually removed to achieve the desired oil-water separation effect.
[0003] Currently, most oil-water separators rely on manual flushing for internal cleaning. This manual cleaning is not only labor-intensive and resource-intensive, but also fails to thoroughly clean hard-to-reach areas and corners, leading to oil buildup and affecting the next use of the device. During filtration, the filter plate can only filter larger residues, causing smaller residues to settle at the bottom. These smaller residues can easily clump together and cause blockages, thus affecting the normal operation of the device. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides an oil-water separator that improves the separation effect, aiming to improve the problems of low and incomplete manual cleaning efficiency and small-particle residue settling and clogging the flow channel in the prior art.

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.
[0032] Reference Figures 1-5This utility model provides an embodiment of an oil-water separator that improves separation efficiency. The separator includes a filter box 1, which provides a relatively enclosed space for oil-water separation. The oil-water separation operation is completed within the filter box. A cover 2 is slidably connected to the top of the filter box 1. The cover 2 facilitates inspection, maintenance, and cleaning of the filter box 1 by personnel. Multiple evenly distributed fixing grooves 9 are provided on the front and rear sides of the inner side of the filter box 1. Multiple evenly distributed fixing strips 10 are slidably connected to the front and rear sides of the inner side of the filter box 1. The fixing strips 10 are slidably connected within the fixing grooves 9 and abut against the bottom of the cover 2. The fixing strips 10, connected within the fixing grooves 9, can fix the drive device, ensuring stable operation. When the drive device is running, the closed cover 2 presses the fixing strips 10 firmly into the fixing grooves 9. Inside, connecting plates 11 are fixedly connected to opposite sides of the fixing strip 10. The connecting plates 11 act as a bridge. Equipment protective shell 12 is fixedly connected to opposite sides of the connecting plates 11. The equipment protective shell 12 protects the motor 13 inside and ensures its normal and stable operation. The motor 13 is fixedly connected to the bottom inside the equipment protective shell 12. The motor 13 can generate the driving force required for automatic cleaning. A connecting rod 14 is fixedly connected to the drive end of the motor 13. Multiple evenly distributed fixing blocks 15 are fixedly connected to the outer periphery of the connecting rod 14. Multiple evenly distributed fan blades 16 are fixedly connected to the outer periphery of the fixing blocks 15. The rotation of the connecting rod 14 can drive the fan blades 16 to rotate, thereby achieving a stirring and cleaning effect. The fan blades 16 are made of waterproof 304 stainless steel, which has waterproof and corrosion-resistant functions, ensuring the long-term use and stable operation of the equipment.
[0033] Reference Figures 1-3 In one embodiment of this utility model: a plurality of evenly distributed support plates 18 are fixedly connected to the right side of the inner wall of the filter box 1. A filter cake basket 17 is abutted against the right side of the inner wall of the filter box 1. The support plates 18 can stably place the filter cake basket 17 inside the filter box 1. The filter cake basket 17 can initially filter out some larger residues to prevent these residues from affecting the subsequent separation effect. The filter cake basket 17 abuts against the top of the support plates 18. A plurality of evenly distributed slag collection boxes 19 are slidably connected to the bottom of the inner side of the filter box 1. The slag collection boxes 19 are slidably connected to the slag discharge port 20. The front of the filter box 1 is opened There are multiple evenly distributed slag discharge ports 20. Small residues that settle to the bottom during the separation process are collected through the slag collection box 19. The slag collection box 19 is then removed through the slag discharge ports 20 and the settled residues are cleaned off. Multiple evenly distributed rotating bars 21 are rotatably connected to the front of the filter box 1. The rotating bars 21 can lock and release the slag collection box 19 to ensure that the slag collection box 19 will not fall out during equipment operation. The rotating bars 21 abut against the front of the slag collection box 19. A sewage pipe 22 is fixedly connected to the front of the slag collection box 19. The sewage pipe 22 is used to discharge impurities and sewage from the filter box 1.
[0034] Reference Figure 2 In one embodiment of this utility model: a water outlet pipe 4 is fixedly connected to the left side of the filter box 1. When the device performs oil-water separation, the water outlet pipe 4 is responsible for discharging the separated water. A water inlet pipe 3 is fixedly connected to the right side of the filter box 1. The water inlet pipe 3 can transmit the oil-water mixture to be processed into the filter box 1. Multiple evenly distributed oil outlet pipes 5 are fixedly connected to the front of the filter box 1. When the device performs oil-water separation, the oil outlet pipes 5 are responsible for discharging the separated oil. A filter baffle 8 is fixedly connected to the left side of the inner wall of the filter box 1. The filter baffle can improve the oil-water separation effect. The filter baffle 8 abuts against the top of the slag collection box 19. Multiple evenly distributed oil baffles 6 are fixedly connected to the opposite side of the inner wall of the filter box 1. The oil baffles 6 can initially achieve oil-water separation. The oil baffles 6 abut against the opposite side of the slag collection box 19. Multiple evenly distributed flow baffles 7 are fixedly connected to the bottom of the inner side of the filter box 1. The flow baffles 7 can slow down the flow rate of water, which helps the oil droplets to float and separate, and also allows more residue to settle into the slag collection box 19.
[0035] Working principle: First, when the equipment needs to be cleaned, the operator opens the cover 2 and injects clean water and cleaning agent into the filter box 1. Then, the fixing strip 10 slides down the fixing groove 9 to the bottom to ensure that it is placed stably. After that, the cover 2 is locked and the motor 13 is started. Its connecting rod 14 drives the fixing block 15 and the fan blade 16 to rotate. The spiral curved surface design of the fan blade 16 forms an upward vortex, which allows the cleaning agent to fully contact the stubborn oil stains on the surface of the box wall and baffle. The attached oil stains are gradually peeled off and dispersed into tiny particles, which are mixed in the water. After cleaning, the motor 13 is turned off and the drain pipe 22 is opened to discharge the sewage into the container. If there are stubborn stains, the above process can be repeated. During this process, no parts need to be disassembled. The 304 stainless steel material of the fan blade 16 ensures that it will not be corroded by long-term contact with the cleaning agent. This design effectively realizes the automated cleaning of the inner wall, baffle and dead corner area of the filter box 1.
[0036] After the oil-water separation process is completed, the residue discharge operation begins. The filter basket 17 has intercepted the larger residues in the oil and water. These residues are blocked above the support plate 18 to prevent them from entering the separation chamber and causing blockage. After cleaning the residue inside the filter basket 17, it can be put back. Some small residues slowly sink to the bottom collection box 19 under the action of gravity. When it is necessary to discharge them, the staff first opens the drain pipe 22 to discharge some sewage and residues. Then, the rotating bar 21 is rotated to release the lock on the collection box 19. The collection box 19 is then pulled out and cleaned. After cleaning, it is put into the filter box 1 through the slag discharge port 20 to complete the residue discharge work.
[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
