Specific implementation

[0028] In the following description, a large number of specific details are given in order to provide a more thorough understanding of the utility model. However, it is obvious to those skilled in the art that the utility model can be implemented without one or more of these details. In other examples, in order to avoid obscuring the utility model, some technical features known in the art are not described.

[0029] Unless the direction indicated by the single definition, the directions such as up, down, left, right, front, back, inside and outside involved in this article are based on the directions such as up, down, left, right, front, back, inside and outside in the drawing shown by the utility model, which is explained here.

[0030] The connection mode can adopt existing modes such as bonding, welding, bolt connection and the like, and the actual needs are accurate.

[0031] For example, Figures 1 to 8The main structure of the cleaning device for an efficient oil-gas separator shown in the figure is a separation cylinder 1 and an inlet pipe and an outlet pipe for the oil-gas separator. The oil-gas mixture is introduced into the oil-gas separator through the inlet pipe, and then the separated oil is output through the outlet pipe.

[0032] A separation screen 3 for oil and gas separation is installed in the separation cylinder 1. The outer wall of the separation screen 3 is installed with the inner wall of the separation cylinder 1 by means of bolts and other structures, so that a seal is formed between the outer wall of the separation screen 3 and the inner wall of the separation cylinder 1.

[0033] A motor 4 is fixedly installed on the top surface of the separation cylinder 1. The rotating shaft of the motor 4 rotates and extends into the separation cylinder 1 and is fixedly connected to a rotating tube 5. Two sets of limiting cylinders 6 are symmetrically fixedly connected to the side walls of the rotating tube 5. A connecting rod 7 is slidably connected inside the limiting cylinder 6. A push spring 10 is fixedly connected inside the limiting cylinder 6. The end of the push spring 10 is fixedly connected to the connecting rod 7. Thanks to the arrangement of the push spring 10 between the inside of the limiting cylinder 6 and the connecting rod 7, the connecting rod 7 fixedly connected thereto can be pushed by the push spring 10 to move toward the inner wall of the separation cylinder 1;

[0034] A mounting plate 8 is fixedly connected between the ends of the two connecting rods 7, and a scraper 9 is installed on the side wall of the mounting plate 8. Thanks to the setting of the push spring 10, the push spring 10 pushes the mounting plate 8 and the scraper 9 to fit closely to the inner wall of the separation screen 3, thereby further improving the scraping efficiency of the scraper 9;

[0035] The outer wall of the rotating tube 5 is rotatably sleeved with a sleeve 11, and a water inlet hole is opened on the side wall of the rotating tube 5, and the water inlet hole is located at the sleeve connection of the sleeve 11. The inner wall of the sleeve 11 and the outer wall of the rotating tube 5 are sealed. Thanks to the water inlet hole opened on the rotating tube 5 being located at the sleeve connection of the sleeve 11, the cleaning liquid in the sleeve 11 can effectively enter the interior of the sleeve 11 through the water inlet hole;

[0036] The outer side of the casing 11 is connected to a water pipe 12, and the water pipe 12 extends to the outside of the separation cylinder 1. The outer wall of the rotating tube 5 is connected to a nozzle 17 for cleaning the inner wall of the oil-gas separator. The nozzle 17 is arranged horizontally, so the cleaning liquid sprayed by the nozzle 17 will be directly sprayed onto the inner wall of the separation screen 3;

[0037] The bottom of the separation screen 3 is symmetrically provided with L-shaped plates 13, and a circular hole 14 is provided at the bottom of the separation screen 3. The side walls of the two L-shaped plates 13 are fixedly connected to springs 15, and a sealing plate 19 is fixedly connected between the ends of the two springs 15. The springs 15 push the sealing plate 19 to block the circular hole 14 provided at the bottom of the separation screen 3, thereby preventing the circular hole 14 from leaking when cleaning is not required.

[0038] And the sealing plate 19 is located below the circular hole 14, the side wall of the sealing plate 19 is fixedly connected with the pressure rod 2, and the pressure rod 2 is slidably extended to below the separation cylinder 1, the pressure rod 2 slidably extended to below the separation cylinder 1 is pulled down, then the sealing plate 19 fixedly connected with the end of the rod wall of the pressure rod 2 is driven to below the separation sieve 3 through the pressure rod 2, and the spring 15 installed between the sealing plate 19 and the L-shaped plate 13 is compressed, so that the circular hole 14 opened at the bottom of the separation sieve 3 is opened, and the sewage in the separation sieve 3 is discharged through the circular hole 14.

[0039] The inner wall of the limiting cylinder 6 is symmetrically provided with two limiting grooves, and the outer wall of the connecting rod 7 is fixedly connected with two limiting blocks 16. The two limiting blocks 16 fixedly connected with the outer wall of the connecting rod 7 are respectively slidably connected in the two limiting grooves in the inner wall of the limiting cylinder 6. Thanks to the two limiting blocks 16 fixedly connected with the outer wall of the connecting rod 7 being respectively slidably connected in the two limiting grooves in the inner wall of the limiting cylinder 6, the sliding direction of the connecting rod 7 can be effectively limited.

[0040] Two L-shaped plates 13 and a sealing plate 19 are fixedly installed with a damping rod 18. Thanks to the setting of the damping rod 18, the two damping rods 18 are respectively slidably located in the two springs 15, so that the oil and gas separator can effectively prevent the vibration from being transmitted to the spring 15 and causing the spring 15 to vibrate and cause the sealing effect of the sealing plate 19 to fail.

[0041] The side of the scraper 9 close to the mounting plate 8 is fixedly connected with two convex blocks, and the side of the mounting plate 8 is provided with a concave groove. The convex blocks on the side wall of the scraper 9 are slidably connected in the concave grooves on the side wall of the mounting plate 8. The scraper 9 and the mounting plate 8 are slidably installed through the convex blocks and the concave grooves, so that the scraper 9 can be easily replaced.

[0042] Working principle

[0043] When the high-efficiency oil-gas separator cleaning device is used, when it is necessary to clean the separation screen 3 in the separation cylinder 1, the water pipe 12 extending to the outside of the separation cylinder 1 is first connected to the pressurized cleaning liquid, and then the cleaning liquid is passed into the interior of the casing 11 through the water pipe 12, and then the cleaning liquid is put into the interior of the rotating tube 5 through the water inlet hole on the rotating tube 5, and then the cleaning liquid is sprayed toward the inner wall of the separation screen 3 through the multiple nozzles 17 on the side wall of the rotating tube 5, and then the motor 4 is started, and the rotating tube 5 fixedly connected to the end of the rotating shaft is driven by the motor 4 to rotate, and at the same time, the nozzle 17 is driven to rotate to evenly spray the cleaning liquid toward the interior of the separation screen 3, so as to remove the oil stains and impurities on the inner wall of the separation screen 3. The immersion and emulsification are carried out, and at the same time, the rotation of the rotating tube 5 will drive the multiple limiting cylinders 6 fixedly connected to the tube wall, the connecting rod 7 inside the limiting cylinder 6, and the scraper 9 fixedly installed at the end of the connecting rod 7 to fit the inner wall of the separation screen 3 and rotate, so as to scrape off the impurities and oil stains emulsified on the inner wall of the separation screen 3, and then the pressure rod 2 that slides and extends to the bottom of the separation cylinder 1 is pulled down, and then the sealing plate 19 fixedly connected to the end of the rod wall is driven to the bottom of the separation screen 3 by the pressure rod 2, and the spring 15 installed between the sealing plate 19 and the L-shaped plate 13 is compressed, so as to open the circular hole 14 at the bottom of the separation screen 3, so as to discharge the sewage inside the separation screen 3 through the circular hole 14.
