Description

Technical Field

[0001] The utility model relates to an oil-water separator, in particular to an anti-deterioration high-efficiency oil-water separator. Background Art

[0002] An oil-water separator is a device that can separate water and oil from an oil-water mixture. When CNC machine tools and other equipment use tool processing equipment, in order to avoid overheating of the tool, the coolant will be sprayed on the tool. At this time, it will inevitably be sprayed on the workpiece. In order to prevent rust before processing, the surface of the workpiece will be coated with anti-rust oil. In this case, the coolant after spraying the tool and the workpiece will be mixed with the oil to form an oil-water mixture. The oil will float on the surface of the coolant, isolating the coolant from the air, causing bacteria to multiply in large numbers, thereby causing the coolant to deteriorate. At this time, the oil floating on the coolant surface can be separated separately through the oil-water separator to prevent deterioration.

[0003] The application with application number 2017201939564.2 and the patent name of a disc-type oil-water separator discloses "an installation box, a rotating disk and a driving motor, the driving motor is fixedly mounted on one side of the installation box, the driving motor is provided with a rotating shaft extending through one side of the installation box into the installation box, the rotating disk is arranged in the installation box, and the center hole of the rotating disk is sleeved on the rotating shaft; it also includes an oil scraper part for separating and discharging the oil adsorbed on the surface of the rotating disk when the rotating disk is rotating, and the oil scraper part is fixed to the installation box" technical solution. When it needs to be used, the installation box is installed in an appropriate position, and then the rotating disk is placed in the coolant to be separated, and then the driving motor is turned on. At this time, the rotating disk rotates and adsorbs the oil on the liquid surface. When the oil passes through the scraper blade, the oil is discharged from the other end of the oil discharge box that is tilted downward, thereby finally achieving the purpose of oil-water separation.

[0004] It can be seen from this that the oil scraper blade used to scrape the oil on both sides of the rotating disk of the current oil-water separator is a sheet-shaped body, and the surface of the sheet-shaped body is a plane. When the oil on the rotating disk is transferred to the upper surface of the oil scraper blade, even if the oil flows downward under the action of gravity, the flow trajectory of the oil on the upper surface of the oil scraper blade will be dispersed, which will cause part of the oil to be adsorbed on the oil scraper blade, and the oil scraper blade will need to scrape the oil again, which will eventually affect the oil scraping efficiency, thereby affecting the overall oil-water separation efficiency.

[0005] At the same time, traditional oil-water separators only have a separation function, and in the actual separation process, many other steps are required, such as how to effectively control the water level of the oil-water mixture so that the rotating disk can accurately absorb the oil on the coolant surface, and how to recycle the coolant after the oil is separated. Most of the above steps are completed manually, resulting in extremely low efficiency of the entire process. Summary of the invention

[0032] The upper inner wall of the oil-water tank 6 is provided with a U-shaped auxiliary step 41 .

[0033] The lower surface of the oil storage seat 7 is provided with an oil drain joint 42 which is connected with the oil storage tank 8; the lower end of the oil drain joint 42 is externally threaded with a sealing cover 43 which matches with it.

[0034] The method of using the utility model is as follows:

[0035] When the oil-water mixture formed by the coolant and the oil needs to be separated from the water, the oil-water mixture can be poured directly into the oil-water tank, or the oil-water mixture can be sent into the oil-water tank 6 through the existing water feeding device. As the oil-water mixture enters the oil-water tank 6, the liquid level sensor 13 can sense the liquid level of the oil-water mixture at the first time. When the liquid level of the oil-water mixture reaches a preset height, the oil-water mixture is stopped from being sent into the oil-water tank 6. At this time, the driving motor 2 is started synchronously. At this time, the lower part of the rotating disk 3 is immersed in the oil-water mixture. As the motor shaft of the driving motor 2 drives the rotating disk 3 to rotate, the rotating disk 3 absorbs the oil floating on the upper surface of the coolant and brings the coolant into the oil drain box 4 through rotation. As the rotating disk 3 rotates forward, the inclined The upper edge of the scraper 39 will scrape the oil on the surface of the rotating disk 3. Since the left and right inclined scrapers 39 are arranged on the left and right sides of the guide plate 38, and the upper ends of the inclined scrapers 39 are inclined outward, the guide plate 38 and the left and right inclined scrapers 39 are combined to form an oil storage tank 44 similar to a V-shaped groove for storing the oil scraped from the rotating disk 3. The guide plate 38 is fixed on the lower inner wall of the oil drain box 4. At the same time, the front end of the oil drain box 4 is tilted downward, so the front end of the guide plate 38 is also tilted downward. When the inclined scraper 39 scrapes into the oil storage tank 44 formed by the guide plate 38 and the left and right inclined scrapers 39, the oil in the oil storage tank 44 will flow toward the front and bottom, and finally discharged into the oil storage tank 8 through the front end of the oil drain box 4, thereby realizing the separate separation of the oil.

[0036] As the oil floating on the coolant surface is separated, the coolant remaining in the oil-water tank 6 is clean coolant, and then the clean coolant can be transferred to facilitate the delivery of a new batch of oil-water mixture into the oil-water tank 6 for the next oil-water separation. When the clean coolant in the oil-water tank 6 needs to be transferred, the opening and closing cylinder 32 can be started. At this time, the piston rod of the opening and closing cylinder 32 will drive the opening and closing member 33 to move upward. When the opening and closing member 33 moves up to a certain stroke, the opening and closing member 33 no longer cuts off and blocks the drain hole 11, and the oil-water tank 6 is connected with the water suction tank 9 through the drain hole 11. The coolant continuously enters the water suction groove 9, and the coolant enters the water delivery chamber 19 through the water inlet hole 21. At the same time, the motor 1501 of the water pump 15 is started, and the motor shaft of the motor 1501 of the water pump 15 drives the impeller 20 to rotate, thereby driving the coolant in the water delivery chamber 19 to rotate and flow, so that suction is generated at the water inlet hole 21, and the coolant in the water suction groove 9 is continuously sucked into the water delivery chamber 19, and then transported to the lead-out joint 24 through the water outlet joint 22. The lead-out joint 24 can be connected to the coolant tank through a pipeline to achieve rapid recovery of the coolant.

[0037] In summary, it can be known that the utility model can directly sense the liquid level of the oil-water mixture in the oil-water tank 6 through the liquid level sensor 13, and control the liquid level of the oil-water mixture in real time, so as to accurately control the depth of the lower part of the rotating disk 3 sinking into the oil-water mixture, and effectively ensure the adsorption effect of the rotating disk 3. When the rotating disk 3 absorbs the oil in the oil-water mixture through rotation, the inclined scrapers 39 on the left and right sides of the guide plate 38 will scrape the oil on the surface of the rotating disk 3. At the first time when the oil is scraped off, the inclined scraper 39 will guide the oil to the oil storage tank 44 formed by itself and the guide plate 38, which effectively prevents the oil from being scraped off the surface of the rotating disk 3 and then mixed with the oil. The intersection of the rotating disks 3 causes the oil to be absorbed by the rotating disks 3 again, thereby effectively preventing the oil scraped from the rotating disks 3 from being absorbed by the rotating disks 3 again and requiring oil scraping again, effectively improving the oil scraping efficiency, and effectively improving the overall oil-water separation efficiency. After the oil-water mixture in the oil-water tank 6 is separated from the oil, clean coolant remains in the oil-water tank 6, and then the separated coolant can be quickly recovered into the coolant tank through the water pump 15, thereby omitting a large number of subsequent processing steps and reducing a lot of trouble, thereby effectively improving the efficiency of the entire process of processing the oil-water mixture and achieving high efficiency.

[0038] A sealing sleeve 25 is provided inside the lead-out hole 23 and outside the lead-out joint 24. A left limit portion 26 is extended outward from the outer edge of the left end of the sealing sleeve 25 to fit with the right side groove wall of the water suction groove 9. A right limit portion 27 is extended outward from the outer edge of the right end of the sealing sleeve 25 to fit with the right side outer wall of the base 5. The sealing sleeve, the left limit portion 26 and the right limit portion 27 are integrally formed and are all made of rubber. The presence of the sealing sleeve 25 can effectively ensure the sealing between the inner wall of the lead-out hole 23 and the outer wall of the lead-out joint 24 to avoid water leakage.

[0039] The cover plate 10 is fixed to the upper surface of the base 5 by a plurality of evenly distributed fastening screws 28 . This fixing method facilitates the disassembly and assembly of the cover plate 10 , thereby facilitating the disassembly and assembly of the water pump 15 .

[0040] A pull plate 34 extends upward from the right end of the seat plate 29, and a pulling opening 35 is provided on the upper part of the pull plate 34. The seat plate 29 and the upper surface of the cover plate 10 are fixed by a number of evenly distributed auxiliary screws 36. The pulling opening 35 can be tied with a rope to facilitate the use of a crane to move the oil-water separator.

[0041] A sinking slope 37 is provided on the lower hole wall of the right part of the drainage hole 11, and the right end of the sinking slope 37 is inclined downward. The sinking slope 37 can use gravity to make the coolant in the oil-water tank 6 quickly enter the water absorption tank, effectively improving the recovery efficiency of the coolant.

[0042] The guide plate 38 is fixed to the lower inner wall of the oil drain box 4 by a plurality of evenly distributed limit screws 40. This fixing method facilitates the disassembly and assembly of the guide plate 38 and facilitates the replacement of the guide plate 38.

[0043] A U-shaped auxiliary step 41 is provided on the inner wall of the upper part of the oil-water tank 6. The auxiliary step 41 can be used as a limit liquid level. When the liquid level of the oil-water mixture is consistent with the height of the auxiliary step 41, it can be clearly judged that the oil-water mixture has reached the limit liquid level, thereby preventing the oil-water mixture from being too high and affecting the adsorption effect of the rotating disk 3.

[0044] An oil drain joint 42 which is in communication with the oil storage tank 8 is provided on the lower surface of the oil storage seat 7. A sealing cover 43 which matches the oil drain joint 42 is externally screwed on the lower end. The oil drain joint 42 can be used to connect the pipeline. Before oil and water separation, the sealing cover 43 can be screwed out from the lower end of the oil drain joint 42, and then connected to the corresponding pipeline. When the oil drain box 4 sends the separated oil into the oil storage tank 8, it will be directly sent into the pipeline through the oil drain joint 42, and finally transported to the actual required position through the pipeline. An oil collecting barrel can also be placed directly under the oil drain joint 42. When the oil in the oil storage tank needs to be collected, the sealing cover 43 only needs to be screwed out from the lower end of the oil drain joint 42.
