Description

Technical Field

[0001] The utility model relates to the technical field of oil separators, in particular to a novel wall-mounted oil separator with a cylindrical structure. Background Art

[0002] Wall-mounted grease traps are typically small and wall-mounted. Their main enclosures are typically small squares made of sheet metal, requiring numerous steps such as cutting, bending, welding, and polishing, resulting in high production costs. While a wide variety of wall-mounted grease traps are available on the market, they can be broadly categorized by their oil drainage method into two types: powered mechanical scraping and unpowered gravity drainage.

[0003] (1) Unpowered gravity oil drainage. Due to the small size of the main box, the oil-water separation time is short, the oil separation effect is not ideal, and most of the oil is discharged into the underground pipe network along with the water. If the inner wall of the small box is not cleaned in time, the oil will clump and cause blockage. However, its fatal weaknesses are poor oil separation effect and high maintenance cost. The advantages are low technical content and low price.

[0004] (2) Powered mechanical oil scrapers. The installation method of wall-mounted grease separators determines that the main box cannot be made particularly large, so the product performance is comparable to that of unpowered small grease separators. Similarly, poor oil separation effect and high maintenance cost are its fatal weaknesses. The advantage is that it can scrape grease into the oil storage tank.

[0005] Therefore, we propose a new wall-mounted oil separator with a cylindrical structure to solve the above problems. Utility Model Content

[0037] Among them, the slag-water separation unit includes a slag-water separation cylinder 5, a liquid level observation window 6, a drain valve 7 and a flange cover 8. The slag-water separation cylinder 5 is a cylindrical structure. A mounting bracket 10 for mounting on a wall is provided on the back of the slag-water separation cylinder 5, and a drain outlet for draining sewage is provided at the lower part. The drain outlet port is provided with a drain valve 7. A connecting flange 14 is provided on the right side of the slag-water separation cylinder 5. The connecting flange 14 is fixedly connected to the flange cover 8. An oil drain pipe and a drain outlet are installed on the outside of the flange cover 8, and a heating pipe 12 and a temperature control probe 13 are installed on the inside. The main bodies of the heating pipe 12 and the temperature control probe 13 are located inside the slag-water separation cylinder 5, and the tail ends are provided on the outside of the flange cover 8. The tail ends of the heating pipe 12 and the temperature control probe 13 are connected to an external power supply.

[0038] As one of the embodiments, a water inlet valve 1 is provided on the water inlet pipe 16, which is convenient for controlling the entry of wastewater and interrupting the treatment of oily wastewater, and for cleaning other parts; the slag water filtration unit includes a slag water filtration cylinder 3, a detachable filter element 4, a quick-release clamp 15 and a quick-release sealing end cover 17. The upper end of the detachable filter element 4 is pluggable and connected to the inside of the slag water filtration cylinder 3, and the lower end is pluggable and connected to the quick-release sealing end cover 17. The bottom of the slag water filtration cylinder 3 and the quick-release sealing end cover 17 are detachably connected through the quick-release clamp 15, which facilitates the cleaning and replacement of the detachable filter element 4; the detachable filter element 4 adopts a narrow-gap long hole design, which not only ensures the water flow area but also ensures easy cleaning.

[0039] As one of the embodiments, the slag-water separation cylinder 5 has a double-layer structure and is filled with an insulation layer inside to keep the oily wastewater inside warm and prevent the oil from agglomerating due to low temperature and clogging the oil drain port; a liquid level observation window 6 is provided in front of the slag-water separation cylinder 5 to observe the internal liquid level and thereby adjust the water inlet flow rate; the liquid level observation window 6 includes a threaded tube 61, a quartz lens 62 and a sealing cover 63; the tail end of the threaded tube 61 is fixedly connected to the slag-water separation cylinder 5, and the front end is threadedly connected to the sealing cover 63; a quartz lens 62 is provided on the inside of the sealing cover 63, and the liquid level inside the slag-water separation cylinder 5 is observed through the quartz lens 62.

[0040] For corrosion resistance reasons, the oil separator body and accessories are made of SUS304 stainless steel as much as possible.

[0041] The utility model provides a novel cylindrical wall-mounted grease trap with a working principle: When oily wastewater from a restaurant enters the slag water filter unit through the water inlet pipe 16, the removable filter element 4 retains the slag within the slag water filter cylinder 3, and the water flows out the other end into the slag water separator cylinder 5. When the water enters the slag water separator cylinder 5, a small amount of air inside the slag water separator cylinder 5 is discharged through the drain pipe 11, while the majority of the air returns through the water inlet and is squeezed out. Because the inlet and outlet pipes of the slag water separator cylinder 5 are both higher than the top of the slag water separator cylinder 5, and the specific inner wall shape of the cylindrical structure, the separated oil floats to the top of the cylinder. The heating pipe 12 accelerates the separation of oil and water, speeding up the grease's rise. The temperature control probe 12 monitors the temperature inside the cylinder in real time. When the temperature exceeds a preset value, the power is turned off and heating stops. The insulation layer of the slag water separator cylinder 5 ensures that a large amount of heat is not lost. The oil level is observed through the liquid level observation window 6 to confirm the oil is drained through the oil drain valve. When the equipment stops taking in water, close the water inlet valve 1 and remove the quick-release sealing end cover 17 to remove the removable filter element 4 to clean the residue. Regularly remove the flange assembly to clean the oil accumulated inside the slag-water separation cylinder 5.
