Description

Technical Field

[0001] This utility model relates to the technical field of oil-water filtration and separation devices, specifically a combined cyclone oil-water filtration and separation device. Background Technology

[0002] The combined cyclone oil-water filtration and separation device is a commonly used equipment for separating oil-water mixtures, and is widely used in industries such as oil fields, chemicals, machinery manufacturing, and wastewater treatment. This device separates oil and water through the principle of cyclone separation, using centrifugal force to cause the oil and water to separate into layers due to their density difference, thereby achieving efficient separation.

[0003] However, during the oil-water separation process using a combined cyclone separator, the separated liquid contains a small amount of incompletely separated oil. Directly discharging the liquid containing this incompletely separated oil will affect the separation efficiency. Furthermore, the oil-water mixture contains a small amount of solid impurities. After the cyclone separator separates the oil, the separated liquid contains solid impurities, which affect the subsequent liquid separation efficiency, leading to insufficient separation by the cyclone separator. Therefore, we propose a combined cyclone oil-water filtration and separation device. Utility Model Content

[0004] To address the shortcomings of existing combined cyclone oil-water filtration and separation devices, this utility model provides a combined cyclone oil-water filtration and separation device. It features the advantage of using the outer shell of the cyclone separator to drive the oil to swirl, separating and conveying the solid impurities of the liquid to the inside of the funnel. The funnel effectively separates the impurities and the oil, improving the efficiency of liquid separation and purification, and solving the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: a combined cyclone oil-water filtration and separation device, including a cyclone shell, a mixture discharge pipe at the lower end of the cyclone shell, a filter box installed at the lower end of the cyclone shell, an installation jacket installed at the lower end of the filter box, a funnel fixedly connected to the bottom end of the installation jacket, a gear movably sleeved inside the installation jacket, a filter screen fixed at the top end of the gear, a third support fixed at the upper part of the installation jacket, limit sleeves fixedly connected to the outside of the third support in sequence, an impurity discharge pipe installed inside one side of the filter box, and a sedimentation tank placed at the lower end of the funnel.

[0006] Preferably, a feed pipe is installed on one side of the top of the hydrocyclone shell, a top cover is installed on one side of the upper part of the hydrocyclone shell, an oil output pipe is installed inside the top cover, and a swirling device is installed inside the hydrocyclone shell.

[0007] Preferably, the mixture discharge pipe installed at the lower end of the hydrocyclone housing extends into the interior of the filter box, and the sedimentation box is located at the lower end of the funnel.

[0008] Preferably, the filter screen is conical, with filter holes on the outside, and the filter screen is movably sleeved inside the limiting sleeve.

[0009] Preferably, a motor is installed on one side of the funnel, and gears installed on one end of the motor output shaft mesh with each other. A scraper is fixed to the outside of the limiting sleeve, and the scraper is fitted to the outside of the filter screen.

[0010] Preferably, the sedimentation tank has a protective layer installed inside, and a discharge port is installed on one side of the lower part of the sedimentation tank, with a mesh structure inside the discharge port.

[0011] Preferably, the filter box and sedimentation box are clamped and placed on the ground by a first bracket and a second bracket, and the first bracket is located outside the second bracket.

[0012] Compared with existing combined cyclone oil-water filtration and separation devices, this utility model has the following advantages:

[0013] 1. This combined cyclone oil-water filtration and separation device uses a jacket to install a filter screen inside a funnel. The filter screen is placed in layers inside the funnel. When the oil is conveyed downwards, the filter screen filters solid impurities and oil in the oil, and the liquid is discharged downwards. This effectively filters the oil and water after cyclone separation, improving the oil-water separation efficiency. Furthermore, after the motor drives the filter screen to rotate, the scraper removes impurities adhering to the outside of the filter screen, effectively preventing impurities and oil from accumulating on the outside of the filter screen and improving the completeness of oil-water separation.

[0014] 2. This combined cyclone oil-water filtration and separation device separates oil through the outer shell of the cyclone separator, and the multi-layer filtration structure inside the funnel filters the oil again. At the same time, the liquid after secondary filtration is transported to the inside of the sedimentation tank for settling, ensuring the filtration efficiency of oil in the oil and water and avoiding the phenomenon of insufficient separation between them.

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.

[0022] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 A combined cyclone oil-water filtration and separation device includes a hydrocyclone shell 1, a mixture discharge pipe 5 at the lower end of the hydrocyclone shell 1, the mixture discharge pipe 5 drives the oil-water mixture after cyclone filtration inside the hydrocyclone shell 1 to undergo multi-stage filtration and separation, thereby improving the separation efficiency. A filter box 6 is installed at the lower end of the hydrocyclone shell 1, and an installation jacket 7 is installed at the lower end of the filter box 6. The installation jacket 7 is installed at the lower end of the hydrocyclone shell 1 and drives the filtration device to be confined. A funnel 8 is fixedly connected to the bottom end of the installation jacket 7. The funnel 8 drives the oil to be discharged downwards in a concentrated manner. A gear 9 is movably sleeved inside the installation jacket 7. A filter screen 11 is fixed at the top end of the gear 9. A third support 12 is fixed to the upper part of the installation jacket 7. The third support 12 limits the position of the filter screen 11 to ensure the stability of the filter screen 11 when it is confined. Limiting sleeves 13 are fixedly connected to the outside of the third support 12 in sequence. An impurity discharge pipe 15 is installed inside one side of the filter box 6. A sedimentation tank 18 is placed at the lower end of the funnel 8.

[0023] Please see Figure 1A feed pipe 3 is installed on one side of the top of the hydrocyclone shell 1, and a top cover 2 is installed on one side of the upper part of the hydrocyclone shell 1. An oil output pipe 4 is installed inside the top cover 2. A swirling device is installed inside the hydrocyclone shell 1. By installing a swirling device inside the hydrocyclone shell 1, the oil-water mixture is transported to the inside of the hydrocyclone shell 1. After swirling, solid-liquid separation can be performed. The oil is discharged through the oil output pipe 4, and a part of the oil-water mixture is discharged downward through the mixture discharge pipe 5.

[0024] Please see Figure 2 The mixture discharge pipe 5 installed at the lower end of the hydrocyclone shell 1 extends into the interior of the filter box 6. The sedimentation box 18 is located at the lower end of the funnel 8. Pure oil is separated and discharged through the hydrocyclone shell 1. At the same time, some incompletely separated oil and solid impurities are transported to the interior of the filter box 6. The filter box 6 filters the oil. Water slides down and is transported to the interior of the funnel 8. Meanwhile, oil and impurities are discharged through the impurity discharge pipe 15. The sedimentation box 18 performs sedimentation and filtration treatment on the treated oil again.

[0025] Please see Figure 2 The filter screen 11 is conical, with filter holes on its outer surface. The filter screen 11 is movably fitted inside the limiting sleeve 13. Through the conical shape of the filter screen 11 and the filter holes on its outer surface, the initially filtered oil-water mixture falls to the outside of the filter screen 11. The filter screen 11 performs multi-stage filtration on the initially filtered oil-water mixture, and the liquid is discharged downwards. At the same time, the limiting sleeve 13 is fixed to the outside of the third bracket 12. The limiting sleeve 13 is fitted onto the outside of the filter screen 11, and the limiting sleeve 13 limits the position of the filter screen 11 to ensure the stability of the filter screen 11 when it is limited.

[0026] Please see Figure 3 and Figure 4 A motor 10 is installed on one side of the funnel 8. A gear and a gear 9 are installed on one end of the output shaft of the motor 10 and mesh with each other. A scraper 14 is fixed to the outside of the limiting sleeve 13. The scraper 14 is fitted to the outside of the filter screen 11. The scraper 14 is installed on the outside of the limiting sleeve 13 and is fixed to the outside of the filter screen 11. At the same time, the motor 10 is started. The motor 10 drives the gear and the gear 9 to mesh. The gear 9 drives the filter screen 11 to rotate. During the rotation of the filter screen 11, the oil and solid impurities adhering to the outside of the filter screen 11 are controlled to come into contact with the scraper 14. The scraper 14 scrapes off the impurities adhering to the outside of the filter screen 11 to prevent impurities from accumulating on the outside of the filter screen 11 and affecting the filtration effect.

[0027] Please see Figure 2The sedimentation tank 18 is equipped with a protective layer 19 inside. A discharge port 20 is installed on one side of the lower part of the sedimentation tank 18. The discharge port 20 is equipped with a mesh structure inside. When the liquid after multi-stage filtration slides into the sedimentation tank 18 through the protective layer 19 inside the sedimentation tank 18, the protective layer 19 slows down the speed of the sliding liquid, ensuring that the liquid accumulates inside the sedimentation tank 18. At the same time, the sedimentation tank 18 performs sedimentation treatment on the liquid.

[0028] Please see Figure 1 The filter box 6 and sedimentation box 18 are clamped and placed on the ground by the first bracket 16 and the second bracket 17. The first bracket 16 is set outside the second bracket 17. The filter box 6 and sedimentation box 18 are supported by the first bracket 16 and the second bracket 17. The second bracket 17 drives the sedimentation box 18 to be set at the lower end of the filter box 6. When the funnel 8 needs to be disassembled, the first bracket 16 is extended and retracted to move the funnel 8 downward, which improves the convenience of the scraper 14 when it is taken out of the funnel 8.

[0029] Working principle: During use, the oil-water mixture is transported to the inside of the hydrocyclone shell 1 through the feed pipe 3. The hydrocyclone device inside the hydrocyclone shell 1 processes the oil-water mixture. At the same time, the oil output pipe 4 carries the pure oil out, while some incompletely processed oil-water and impurities are transported to the inside of the filter box 6 through the mixture discharge pipe 5. The limiting sleeve 13 filters the passing oil. The liquid after multi-stage filtration slides down through the funnel 8 into the inside of the sedimentation tank 18. The filtered oil is discharged through the impurity discharge pipe 15. The motor 10 is started, and the motor 10 drives the gear 9 to rotate. The gear 9 drives the filter screen 11 to rotate. During the process, the filter screen 11 comes into contact with the outside of the scraper 14. The scraper 14 scrapes off the impurities adhering to the outside of the filter screen 11, improving the cleaning efficiency. The liquid transported to the inside of the sedimentation tank 18 can be further treated by sedimentation, and the impurities in the oil are discharged to the bottom.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
