Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of hydraulic oil production, and particularly relates to a high-cleanliness hydraulic oil blending device and a blending method. BACKGROUND

[0002] Hydraulic oil is a hydraulic medium used by a hydraulic system using liquid pressure energy.

[0003] The patent document with the application number 202020528319.2 discloses that during the preparation of high-cleanliness hydraulic oil, the oil needs to be fully blended. The mixing effect of the existing part of the blending device is poor, and bubbles are generated during the mixing process of the oil. If the bubbles are not removed in time, the quality of the finished product of the hydraulic oil will be affected.

[0004] In addition, the heating method used by the existing part of the blending device cannot uniformly and quickly spread the heat, so that the temperature difference between the inner layer oil and the outer layer oil in the blending device is large within a certain time, thereby causing a large viscosity difference. As a result, part of the oil with large viscosity is easily attached to the inner wall of the container and other parts and cannot participate in the mixing and stirring, thereby affecting the mixing and stirring effect of the oil. In addition, after the blending is completed and the oil is discharged from the inside of the container, a large amount of oil is still attached to the inner wall of the container and the internal parts, and a large amount of impurities are attached to the internal parts, which is not convenient to clean and discharge.

[0051] Second embodiment

[0052] Reference Figures 1-9, based on the high-purity hydraulic oil blending device provided in the first embodiment, there is a large gap between the hollow rods 403 in the actual use process, which cannot make the oil fully and uniformly mixed, thereby reducing the blending effect and easily producing bubbles that cannot be eliminated in time. In addition, during the heating of the oil, since the heating source is located at the center of the blending tank 1, a large temperature difference exists between the oil on the inside and the oil on the outside within a certain time, thereby causing the viscosity of the oil on the inside to be smaller than that of the oil on the outside. Part of the oil on the outside is easily adhered to the inner wall of the blending tank 1 and the internal parts and cannot participate in the mixing and stirring, thereby affecting the mixing and stirring effect of the oil. In addition, after the blending is completed and the oil is discharged from the inside of the blending tank 1, a large amount of oil is still adhered to the inner wall of the blending tank 1 and the internal parts, and a large amount of impurities are adhered to the internal parts, which is not convenient for cleaning and discharging. In order to solve the above problems:

[0053] The hollow rods 403 are provided with spherical capsules 404 at equal intervals. The spherical capsules 404 are provided with air pressure sensors. The spherical capsules 404 are in communication with the hollow rods 403. The spherical capsules 404 are uniformly provided with rubber spikes 405. The bottom of the spherical capsules 404 is uniformly provided with pressure relief valves 406. Specifically, the side of the center hole of the spherical capsule 404 is provided with an air hole. The side of the hollow rod 403 is provided with a guide hole in communication with the air hole. The hollow rod 403 is moved up and down to drive the spherical capsule 404 to rise and fall while rotating and stirring, so as to stir the oil and further improve the mixing effect. The rubber spikes 405 on the outside of the spherical capsule 404 can pierce the bubbles in the oil during the stirring process, so as to eliminate the bubbles and improve the blending degree of the hydraulic oil. The air pressure sensor is used for monitoring the air pressure value in the spherical capsule 404.

[0054] The top of the rotating seat 402 is provided with an electric push rod 407 corresponding to the telescopic pipe 408. The end of the electric push rod 407 is fixedly connected with the telescopic end of the telescopic pipe 408. Specifically, the telescopic movement of the electric push rod 407 can drive the telescopic end of the telescopic pipe 408 to telescope, thereby driving the hollow rod 403 to move along the radial direction, and the telescopic end of the lower telescopic rod 401 is synchronously telescoped.

[0055] The bottom of the rotating seat 402 is uniformly provided with an electric telescopic rod 5. The telescopic end of the electric telescopic rod 5 is fixedly connected with the fixed end of the lower telescopic rod 401. Specifically, the extension of the electric telescopic rod 5 can reversely lift the telescopic pipe 408 upward, thereby driving the hollow rod 403 to move upward. The contraction of the electric telescopic rod 5 can drive the hollow rod 403 to move downward. The rotation of the blending motor 9 can drive the shaft rod 2 to rotate. During the stirring and mixing process, the electric telescopic rod 5 continuously telescopes, so that the rotating seat 402 reciprocally moves up and down while rotating. The telescopic pipe 408 drives the hollow rod 403 to rise and fall, and the oil is stirred by the rising and falling of the spherical capsule 404.

[0056] The fixed end of the telescopic pipe 408 is connected with the external gas supply system through the trachea, and the pressure relief valve 406 is arranged obliquely. Specifically, the telescopic pipe 408 is made of hard material. The external gas supply system passes high-pressure gas into the telescopic pipe 408, and then into the hollow rod 403 and into the spherical capsule 404, so as to expand the spherical capsule 404.

[0057] In use, especially in the process of mixing and stirring by rotating the hollow rod 403, the external gas supply system passes high-pressure gas into the telescopic pipe 408, and then into the hollow rod 403 and into the spherical capsule 404, so as to expand the spherical capsule 404. The external gas supply system is used for irregularly sucking and inflating, so that the spherical capsule 404 continuously and irregularly expands and shrinks. In the process of irregular expansion and shrinkage of the spherical capsule 404, the oil can be further stirred and mixed. At the same time, the electric telescopic rod 5 continuously extends and retracts, so that the rotary seat 402 reciprocates up and down while rotating. The telescopic pipe 408 drives the hollow rod 403 to ascend and descend, so that the spherical capsule 404 reciprocates up and down. The oil can be stirred by the spherical capsule 404. The oil is fully stirred and mixed by the reciprocating motion, rotating motion and expansion and shrinkage of the spherical capsule 404, so as to improve the stirring and mixing effect. The oil between the hollow rods 403 is also fully mixed and stirred. The rubber prongs 405 on the outside of the spherical capsule 404 are used to break and eliminate the generated bubbles. The irregular expansion and shrinkage of the spherical capsule 404 increases the gap between the rubber prongs 405, so that the bubbles distributed unevenly can be fully broken and eliminated, and the bubble elimination effect is improved.

[0058] Since the distance between the innermost spherical capsule 404 and the electric heating rod 1604 is the smallest, the temperature of the innermost spherical capsule 404 is greater than that of the outermost spherical capsule 404, and the air pressure value in the innermost spherical capsule 404 is greater than that in the outermost spherical capsule 404 due to the effect of thermal expansion, and the volume of the innermost spherical capsule 404 is greater than that of the outermost spherical capsule 404. After stirring and mixing for a specified time, when the difference between the air pressure value detected by the air pressure sensor in the innermost spherical capsule 404 and the air pressure value detected by the air pressure sensor in the outermost spherical capsule 404 is greater than the set threshold value, it is actively judged that the temperature difference between the oil liquid on the inside and the oil liquid on the outside is large, and the oil liquid on the inside and the outside is unevenly heated. At this time, the external air supply system still maintains irregular air extraction and air charging, the electric push rod 407 is started, the extension and retraction end of the telescopic pipe 408 is driven to extend and retract by the continuous extension and retraction of the electric push rod 407, and the hollow rod 403 is driven to reciprocate along the radial direction. At this time, the extension and retraction end of the lower telescopic rod 401 synchronously extends and retracts, and the radial reciprocating motion of the spherical capsule 404 is realized. In the process of radial reciprocating motion of the spherical capsule 404, the high-temperature heat in the middle part can be quickly and uniformly diffused to the oil liquid on the outside, so that the temperature of the oil liquid on the inside is close to or equal to that of the oil liquid on the outside. At the same time, the radial reciprocating motion of the hollow spherical capsule 404 can realize more sufficient stirring and mixing of the oil liquid. When the air pressure sensor detects that the air pressure value in the innermost spherical capsule 404 is equal to or close to that in the outermost spherical capsule 404, it is actively judged that the oil liquid on the inside and the oil liquid on the outside in the blending tank 1 are uniformly heated.

[0059] However, when the temperature of the oil liquid inside is still greater than the temperature of the oil liquid outside before the air pressure value inside the innermost spherical capsule 404 reaches the air pressure value inside the outermost spherical capsule 404, or is close to the air pressure value inside the outermost spherical capsule 404, and the viscosity of the oil liquid is lower as the temperature is higher, the oil liquid outside with lower temperature is prone to adhere to the inner wall of the blending tank 1 and the internal components at this time. When it is detected that the air pressure value inside the innermost spherical capsule 404 is greater than the air pressure value inside the outermost spherical capsule 404, it can be judged that the temperature of the oil liquid inside is greater than the temperature of the oil liquid outside. At this time, the driving motor 27 is started to drive the rotating ring 21 to rotate through the driving gear 28 and the ring gear 25, the rotating ring 21 drives the inner rotating plate 23 to rotate, and the inner rotating plate 23 drives the scraper 24 to rotate to scrape the inner wall of the blending tank 1, so that the oil liquid adhering to the inner wall of the blending tank 1 is scraped off and participates in the mixing and stirring. However, the oil liquid with greater viscosity is prone to adhere to the scraper 24, which affects the scraping effect. Therefore, while the mixing and stirring are performed, the external air supply system is used to perform irregular air suction and air charging, so that the spherical capsules 404 are irregularly expanded and contracted, and the electric push rod 407 is used to drive the spherical capsules 404 to reciprocate along the radial direction. The outermost spherical capsule 404 after expansion collides with the inner rotating plate 23, so that the scraper 24 vibrates, thereby causing the oil liquid adhering to the scraper 24 to shake off, preventing the scraper 24 from adhering to too much oil liquid and affecting the scraping effect of the oil liquid adhering to the inner wall of the blending tank 1.

[0060] In addition, after the blending is completed and the oil liquid is discharged from the blending tank 1, part of the oil liquid still adheres to the inner wall of the blending tank 1, the heat-conducting fins 1607 and the spherical capsules 404, and the gap between the heat-conducting fins 1607 and the gap between the rubber spikes 405 still have a lot of impurities. Therefore, after the blending is completed and the material is discharged from the blending tank 1, the external air supply system is used to continuously charge high-pressure gas into the spherical capsules 404, so that the air pressure value inside the spherical capsules 404 reaches the pressure relief value of the pressure relief valve 406. The gas inside the spherical capsules 404 can be discharged through the pressure relief valve 406 at the bottom of the spherical capsules 404. Since the pressure relief valve 406 is inclinedly arranged, the continuous extension and contraction of the electric telescopic rod 5 drives the spherical capsules 404 to reciprocate up and down, the driving of the blending motor 9 drives the spherical capsules 404 to rotate, and the continuous extension and contraction of the electric push rod 407 drives the spherical capsules 404 to reciprocate along the radial direction. The high-pressure gas flow discharged can be discharged to the inner wall of the blending tank 1, the gap between the heat-conducting fins 1607 and the adjacent spherical capsules 404, so that the oil liquid adhering to the inner wall of the blending tank 1 is blown down, and the oil liquid and impurities gathered between the heat-conducting fins 1607 and the rubber spikes 405 are blown off. Under the expansion of the spherical capsules 404, the gap between the rubber spikes 405 increases, which is helpful for the blowing off of the oil liquid and impurities. The blown-off impurities and oil liquid are discharged through the dropping chute 12, so that the inside of the blending tank 1 is cleaned, and the residual oil liquid and impurities are thoroughly cleaned out.
