Description

Technical Field

[0001] This utility model relates to the field of multi-stage oil removal technology, specifically a multi-stage oil removal device based on cyclone oil removal. Background Technology

[0002] Industrial production such as petrochemicals, steel and coal processing, machinery processing, and food processing, as well as daily life, generate large amounts of oily wastewater. Oil has a serious impact on ecosystems, soil, and water bodies. Floating oil flowing into water bodies can form an oil film that cuts off the oxygen source. Furthermore, emulsified and dissolved oils in the water consume dissolved oxygen during microbial decomposition, leading to oxygen deficiency and making it impossible for fish and aquatic organisms to survive. Oily wastewater entering the soil can also form an oil film, hindering the reproduction of soil microorganisms and damaging the soil's granular structure. Hydrocyclone oil removal technology utilizes the principle of hydraulic cyclone to achieve oil-water separation.

[0003] However, existing cyclone oil removal devices remove the upper layer of oil by utilizing the oil-water stratification characteristics formed after the sewage swirls. But during the oil discharge process, the oil layer will adhere to the inner wall of the oil removal tank under the movement of the water flow, causing the oil layer to form a wall-mounted structure. This formation of the oil layer on the inner wall will cause inconvenience to the oil removal work of the oil removal tank. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a multi-stage oil removal device based on cyclone oil removal, which has the advantages of scraping off the oil layer attached to the inner wall of the oil removal tank, facilitating the disassembly and assembly of the scraper, and improving the practicality of the scraper, thus solving the problems mentioned in the background art.

[0020] 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.

[0021] Please see Figure 1 , Figure 2 and Figure 4 A multi-stage oil removal device based on cyclone degreasing includes an oil removal tank body 1. An output pipe 2 is fixedly installed on the upper left side of the oil removal tank body 1. A rotating rod 3 is installed inside the oil removal tank body 1, providing power for the rotation of a scraper 6 inside the oil removal tank body 1. Discs 4 are fixedly sleeved on the outer walls of the upper and lower ends of the rotating rod 3. The scraper 6 is movably installed on the outer side of the discs 4 via fastening bolts 5. By changing the installation position of the fastening bolts 5, the interaction between the scraper 6 and the discs 4 can be adjusted. Disassembly or installation: A discharge pipe 17 is fixedly installed at the lower end of the oil tank body 1. A filter cotton 7 is movably installed on the inner wall of the discharge pipe 17. A double-layer filter screen 8 located below the filter cotton 7 is movably snapped onto the inner wall of the discharge pipe 17. The filter cotton 7 and the double-layer filter screen 8 provide a multi-stage filtration effect. Since valves controlling the flow of materials are installed on the output pipe 2, input pipe 10, and discharge pipe 17, after the valve on the discharge pipe 17 is opened, the material passes through the filter cotton 7 and the double-layer filter screen 8 in sequence for multi-stage filtration.

[0022] The upper end of the oil removal tank body 1 is movably connected to the tank cover body 9 located at the upper end of the rotating rod 3. The tank cover body 9 is movably connected to the oil removal tank body 1 via an electric push rod 19. An input pipe 10 is fixedly installed at the lower right end of the oil removal tank body 1. A one-way valve is provided on the input pipe 10. A support frame 11 located below the input pipe 10 is fixedly sleeved on the outer wall of the oil removal tank body 1.

[0023] A rotary motor 12 is fixedly installed on the upper end of the rotating rod 3, located above the tank cover body 9, and a reducer is provided on the output shaft of the rotary motor 12. A sleeve rod 13 is rotatably connected to the outer wall of the lower end of the rotating rod 3. Extension rods 14 are evenly distributed on the outer wall of the sleeve rod 13, and the end of the extension rod 14 away from the sleeve rod 13 is fixedly connected to the inner wall of the oil removal tank body 1.

[0024] Please see Figure 2 , Figure 3 and Figure 5 Connecting rods 15 are evenly distributed on the outer wall of the disc 4. A locking block 16 located inside the scraper 6 is fixedly installed at the end of the connecting rod 15 away from the disc 4. The inner wall of the locking block 16 is threadedly connected to the outer wall of the fastening bolt 5. When the rotating rod 3 rotates, it drives the scraper 6 to rotate inside the oil removal tank body 1 through the connection of the disc 4, connecting rods 15, locking block 16, fastening bolt 5 and fixing block 18. When the scraper 6 rotates, it scrapes off the material adhering to the inner wall of the oil removal tank body 1, preventing the material from forming a wall-hanging effect on the inner wall of the oil removal tank body 1.

[0025] Fixing blocks 18 are fixedly installed at the upper and lower ends of the inner side of the scraper 6. The outer wall of the fixing block 18 is movably engaged with the inner wall of the locking block 16. The inner wall of the fixing block 18 is movably engaged with the locking block 16 by fastening bolts 5. Since the fastening bolts 5 connect the locking block 16 and the fixing block 18, the scraper 6 can be replaced after wear by changing the connection method between the fastening bolts 5 and the locking block 16 or the fixing block 18.

[0026] A protective cover 22 located outside the rotary motor 12 is fixedly installed on the upper end of the can lid body 9. An upper end plate 20 is fixedly installed on the back of the can lid body 9. An electric push rod 19 is fixedly connected to the lower end of the upper end plate 20. When the power of the electric push rod 19 is turned on, the extension movement of the output shaft inside the electric push rod 19 is used to drive the separation of the can lid body 9 from the oil removal can body 1 through the connection of the output pipe 2. A lower end plate 21 is fixedly installed on the end of the electric push rod 19 away from the upper end plate 20, and the front end of the lower end plate 21 is fixedly connected to the back of the oil removal can body 1.

[0027] Working principle: In use, firstly, the material to be degreased is added into the oil removal tank body 1 through the input pipe 10. A one-way valve is installed on the input pipe 10. The power to the rotary motor 12 is turned on, causing the rotary rod 3 to rotate inside the oil removal tank body 1. Simultaneously, the rotating rod 3, through the connection of the disc 4, connecting rod 15, locking block 16, fastening bolt 5, and fixing block 18, drives the scraper 6 to rotate inside the oil removal tank body 1. The scraper 6 scrapes off the material adhering to the inner wall of the oil removal tank body 1, preventing material from forming a wall-hanging effect. Then, since valves controlling material flow are installed on the output pipe 2, input pipe 10, and discharge pipe 17, after the valve on the discharge pipe 17 is opened, the material flows sequentially through the filter cotton 7, double-layer filter... Through multi-stage filtration on the screen 8, the oil floating on the surface is discharged from the output pipe 2 to the outside of the oil removal tank body 1. Finally, when it is necessary to clean the inside of the oil removal tank body 1, the power of the electric push rod 19 is turned on. The extension movement of the output shaft inside the electric push rod 19 drives the tank cover body 9 to separate from the oil removal tank body 1 through the connection of the output pipe 2. Since the fastening bolt 5 connects the locking block 16 and the fixing block 18, the replacement of the scraper 6 after wear can be achieved by changing the connection method of the fastening bolt 5 and the locking block 16 or the fixing block 18. When it is necessary to clean the filter cotton 7 or the double-layer filter screen 8, the filter cotton 7 and the double-layer filter screen 8 can be pulled out from the inside of the discharge pipe 17. The contact surfaces of the filter cotton 7 and the double-layer filter screen 8 with the discharge pipe 17 are all equipped with sealing rings to prevent liquid from flowing out.
