Description

Technical Field

[0001] The utility model relates to the technical field of hydrocyclones, and particularly relates to a self-cleaning hydrocyclone for power plants. Background Art

[0002] A fluid hydrocyclone is a common separation and classification device, which commonly uses the principle of centrifugal sedimentation. When the two-phase mixed liquid to be separated enters the hydrocyclone tangentially from the periphery at a certain pressure, a strong three-dimensional elliptical strong rotational shear turbulent motion is generated. Due to the particle size difference between the coarse particles and the fine particles, the centrifugal force, centripetal buoyancy, fluid drag force, etc. acting on them are different. Under the action of centrifugal sedimentation, most of the coarse particles are discharged through the underflow port of the hydrocyclone, while most of the fine particles are discharged through the overflow pipe, so as to achieve the purpose of separation and classification.

[0003] The traditional hydrocyclone can usually only clean the outside of the hydrocyclone, and it is not convenient to effectively clean the inside of the hydrocyclone, resulting in easy caking inside the hydrocyclone, thus affecting the use effect of the hydrocyclone.

An overflow pipe 4 is fixedly communicated with the right side of the surface of the cylindrical section 1. A cleaning mechanism 5 is arranged inside the cylindrical section 1. The cleaning mechanism 5 includes a scraping component 501 and a flushing component 502;

[0025] The scraping component 501 includes a mounting block 5011, an annular scraping plate 5012, a rotating shaft 5013 and an annular groove 5014. The annular scraping plate 5012 is fixedly sleeved on the surface of the mounting block 5011, and the surface of the annular scraping plate 5012 is in mutual fit with the inner wall of the cylindrical section 1. The rotating shaft 5013 is fixedly connected to the middle of the top of the mounting block 5011. The annular groove 5014 is opened on the top of the mounting block 5011.

[0026] In this embodiment: By setting the cleaning mechanism 5, the electric cylinder 12 can drive the cleaning mechanism 5 to move up and down flexibly. The micro pump 10 can introduce the flushing water into the water storage bin 7. The kinetic energy generated when the flushing water flows will drive the impeller 8 to rotate. When the impeller 8 rotates, it will drive the rotating shaft 5013 to rotate. When the rotating shaft 5013 rotates, it will drive the mounting block 5011 and the annular scraping plate 5012 to rotate together, so that the annular scraping plate 5012 can rotate while moving, thereby effectively scraping the residues on the inner wall of the cylindrical section 1.

[0032] In this embodiment: Through the above settings, the kinetic energy generated when the flushing water flows drives the impeller 8 to rotate. When the impeller 8 rotates, it drives the rotating shaft 5013 to rotate, while the water storage bin 7 does not rotate with the rotating shaft 5013. When the rotating shaft 5013 rotates, it drives the mounting block 5011 and the annular scraper 5012 to rotate together, so that the annular scraper 5012 can rotate while moving, and the flushing water can enter the inside of the annular pipe 5021 through the connecting pipe 9, facilitating the flushing work inside the cylindrical section 1.

[0033] As a technical optimization solution of the present utility model, a micro pump 10 is fixedly connected to the top of the cylindrical section 1, and the water outlet end of the micro pump 10 extends to the inside of the cylindrical section 1.

[0034] In this embodiment: Through the above settings, the micro pump 10 can be externally connected to a flushing water source, so that the micro pump 10 can introduce the flushing water into the inside of the water storage bin 7, thereby improving the use effect of the cleaning mechanism 5.

[0035] As a technical optimization solution of the present utility model, a sliding ring 11 is slidably connected to the inside of the annular groove 5014, and the sliding ring 11 is fixedly connected to the bottom of the support ring 6.

[0036] In this embodiment: Through the above settings, the annular groove 5014 can limit the slip ring 11, so that the rotation trajectory of the mounting block 5011 can be limited, thereby improving the stability of the scraping assembly 501 during use.

[0037] As a technical optimization solution of the present utility model, an electric cylinder 12 is fixedly connected to the top of the inner wall of the cylindrical section 1, and the telescopic end of the electric cylinder 12 is fixedly connected to the top of the water storage tank 7.

[0039] As a technical optimization solution of the present utility model, a brush 13 is provided on the surface of the water storage tank 7, and the brush 13 is in mutual contact with the inside of the cylindrical section 1.

[0040] In this embodiment: By setting the brush 13, the brush 13 can clean the area above the top of the scraper, and at the same time can further clean the inner wall of the cylindrical section 1 after being scraped by the scraper, thereby improving the cleaning effect of the cleaning mechanism 5.

[0041] Working principle: First, connect the micro pump 10 to an external cleaning water source, then start the micro pump 10 and the electric cylinder 12. The micro pump 10 will introduce the flushing water into the water storage tank 7. The kinetic energy generated when the flushing water flows will drive the impeller 8 to rotate. When the impeller 8 rotates, it will drive the rotating shaft 5013 to rotate. When the rotating shaft 5013 rotates, it will drive the mounting block 5011 and the annular scraper 5012 to rotate together. When the annular scraper 5012 rotates, it can scrape the residues on the inner wall of the cylindrical section 1. Then, the flushing water in the water storage tank 7 will enter the annular pipe 5021 through the connecting pipe 9. Then, after being pressurized by the high-pressure nozzle 5022, the flushing water can perform high-pressure flushing on the inner wall of the cylindrical section 1, so that the residues will be separated from the inner wall of the cylindrical section 1, facilitating the scraping assembly 501 to scrape them. And the electric cylinder 12 will drive the entire cleaning mechanism 5 to move up or down, so that the annular scraper 5012 and the high-pressure nozzle 5022 can comprehensively clean the inner wall of the cylindrical section 1. The cleaned residues and dirty water will be discharged through the bottom of the conical section 2, and the self-cleaning work of the hydrocyclone can be completed.

[0042] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
