Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic oil production equipment, and more specifically, to a hydraulic oil heating reaction device. Background Art

[0002] Hydraulic oil is an essential and important liquid medium in hydraulic systems. It is not only used as a lubricant, but also an important carrier for transmitting power, controlling components, cooling components, etc. Hydraulic oil is usually composed of base oil and various additives. The base oil is the carrier of hydraulic oil and determines the basic properties of hydraulic oil. Additives are added to improve the performance of hydraulic oil. At present, in the production process of hydraulic oil, high-temperature heating is conducive to the reaction between base oil and additives, and helps to improve the stability of hydraulic oil. Therefore, it is necessary to use heating reaction equipment to heat the base oil and additives of different proportions. However, due to the high viscosity of the raw materials, on the one hand, a lot of raw materials will adhere to the inside of the container, which brings inconvenience to the discharge of the reaction; on the other hand, the uneven mixing between the additives and the base oil leads to poor heating reaction effect.

The outer jacket 3 is provided with a heating medium injection port 19 at the bottom and a heating medium outlet 18 at the top. This arrangement can extend the flow path of the heating medium, so that the heating medium and the internal raw materials can maintain sufficient heat exchange, thereby improving the heating effect. The cover body 2 is installed on the top of the kettle body. The kettle body includes a main kettle body, a tapered section 14 and a discharge section 15 arranged from top to bottom, wherein the outer diameter of the main kettle body is larger than the outer diameter of the discharge section 15, and the tapered section 14 is located between the two, and the outer diameter gradually decreases from top to bottom. A feed port 20 is arranged on the cover body 2, and a discharge port 16 is arranged at the bottom of the discharge section 15.

[0019] The stirring assembly is mounted on the cover 2, and includes a driving motor 4, a central shaft 5, and a stirring part arranged on the central shaft 5. The driving motor 4 is mounted on the upper part of the cover 2 through a motor seat, and the output end of the driving motor 4 is connected to the central shaft 5. The central shaft 5 extends through the cover 2 into the interior of the kettle 1 and remains coaxial with the kettle 1. The central shaft 5 is rotatably connected to the cover through a support bearing, thereby supporting the stable rotation of the central shaft. The stirring part is located inside the kettle 1, and includes a vertical stirring rod 6, an upper stirring rod 7, and a lower stirring rod 8. The vertical stirring rod 6 is located radially outside the central shaft 5. The upper part of the vertical stirring rod 6 is connected to the upper part of the central shaft 5 through the upper stirring rod 7, and the lower part is connected to the lower part of the central shaft 5 through the lower stirring rod 8. The lower stirring rod 8 is in an inclined state, and its inclination angle is adapted to the inclination slope of the conical section 14. Two stirring parts are arranged symmetrically relative to the central axis, and two spirally distributed stirring blades 9 are connected between the two stirring parts. The stirring blades 9 are connected between the upper stirring rod 7 of the stirring part and the lower stirring rod 8 of the other stirring part. The stirring part and the stirring blades 9 are driven to rotate by the central axis 5, so as to achieve a large-scale and comprehensive stirring and mixing effect.

[0020] The scraping device includes a scraping bar 10, which is arranged on the outside of the vertical stirring rod 6 and the lower stirring rod 8, and is used to scrape the side wall of the kettle body (i.e., the inner wall of the main kettle body) and the bottom wall of the kettle body (i.e., the inner wall of the tapered section 14). The scraping bar 10 is connected to the vertical stirring rod 6 or the lower stirring rod 8 through at least two adjustable connecting parts, and the adjustable connecting parts include a screw 11, a bearing 12 and a screw handle 13. The vertical stirring rod 6 and the lower stirring rod 8 are both provided with threaded holes, and the screw 11 is inserted into the threaded holes. One end of the screw 11 is rotatably connected to the scraping bar 10 through the bearing 12, and the other end is provided with a screw handle 13. If necessary, the screw handle 13 can be rotated to screw in or out the screw 11, and the scraping force can be adjusted by adjusting the position of the scraping bar 10 relative to the inner wall of the kettle body to ensure the best scraping effect without damaging the inner wall of the kettle body.

[0021] To ensure smooth discharge without blockage after the reaction is completed, the lower end of the central shaft 5 extends into the discharge section 15, and a spiral discharge blade 17 is provided on the outer side of the central shaft 5 at a position corresponding to the discharge section 15. The spiral discharge blade 17 can be driven by the central shaft 5 to rotate and transport the material downward to avoid blockage and accumulation of materials that are difficult to discharge.

The heating method of the heating medium has a large heat conduction contact area and a relatively uniform heat transfer effect, which is conducive to improving the heating effect; turn on the drive motor, and the central axis drives the stirring part and the spiral stirring blade to rotate under the action of the drive motor. The setting form of the stirring part and the stirring blade is relatively novel and unique, and the rotation has a large effective area, which can effectively improve the raw material mixing efficiency, the mixing is relatively uniform, and the raw material heating reaction effect is comprehensively improved. In addition, during the rotation process, the stirring part drives the scraper to scrape off the raw materials adhered to the side wall and the bottom wall of the kettle body, solving the problem of raw materials hanging on the wall. The subsequent discharge is assisted by the conveying effect of the spiral discharge blade to ensure smooth and complete discharge and avoid material waste. In addition, in this embodiment, the position of the scraper relative to the inner wall of the kettle body can be adjusted, so that the best scraping effect can be achieved during the movement of the scraper, which is highly practical.
