Description

Technical Field

[0001] This application relates to the field of turbine oil preparation equipment, specifically to a reaction vessel for preparing antioxidant, corrosion-resistant, and long-life turbine oil. Background Technology

[0002] In recent years, with the rapid development of the national economy, my country's power industry has also developed rapidly. New thermal power plants and expansions of existing ones are all moving towards larger capacities, generally with a single unit capacity of at least 300MW, with 600MW being the most common, and some even reaching 1000MW. As the single-unit capacity of steam turbines increases, the steam parameters (temperature and pressure) of steam turbines are constantly improving. Supercritical high-power steam turbine units with good economic efficiency have become the main development direction of China's power industry. Therefore, high-quality turbine oil will play a dominant role.

[0003] Chinese patent document CN215428646U discloses a low-loss gasoline engine oil preparation device, including a rectangular frame. A tank is fixedly installed between the left and right side walls of the rectangular frame. A feeding pipe is provided on the upper surface of the tank, and a discharge pipe is provided on the lower surface of the tank. A heat exchange pipe is provided on the outer surface of the inner tank corresponding to the cavity, and the heat exchange pipe is connected to a heating mechanism. A drive mechanism is fixedly installed on the left side of the outer tank, and a stirring shaft is provided on the drive mechanism. The right side of the stirring shaft is fixedly connected to an adjustment mechanism. A gas collection box is connected to the feeding pipe through a recovery mechanism. This patent improves the mixing effect and efficiency of gasoline engine oil preparation. It uses solar energy to preheat the raw materials, ensuring uniform heating and low operating costs. It can also condense and recover the discharged raw material gas, reducing losses during the preparation process and avoiding environmental pollution.

[0004] However, the aforementioned patent does not include any pretreatment of the raw materials, which means that impurities such as moisture and waste residue mixed in the raw materials will continue to exist in the tank, thereby affecting the quality of the engine oil preparation.

[0025] The present application will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0026] like Figure 1-4 As shown, a reactor for preparing antioxidant, corrosion-resistant, and long-life turbine oil includes a horizontal reactor body 1. The reactor body 1 has a feed pipe 11 at the top and a discharge pipe 12 at the bottom. A stirring shaft 2 driven by a motor 21 is installed inside the reactor body 1. Several U-shaped stirring rods 22 are provided on the outer wall of the stirring shaft 2. The lower part of the feed pipe 11 extends to the inner side of the reactor body 1. A sleeve 3 is threadedly connected to the lower part of the feed pipe 11. A filter plate 30 is provided at the end of the sleeve 3 away from the feed pipe 11. The filter plate 30 is made of water-absorbing material. The material is fed into the reactor body 1 through the feed pipe 11. Before entering the reactor body 1, the material enters the sleeve 3 and then passes through the filter plate 30. During the passage, the filter plate 30 can trap fixed impurities in the material and absorb moisture from the material, thus filtering the material and ensuring that the material can be reliably stirred by the stirring rod 22 after entering the reactor body 1, thereby improving the reaction effect and ensuring that the oil made from the material has high quality.

[0027] A bearing seat 13 is provided on both sides of the inner wall of the reactor body 1. One end of the stirring shaft 2 passes through one bearing seat 13, and the other end of the stirring shaft 2 passes through another bearing seat 13. The motor 21 is located on the outside of the reactor body 1. With the support of the bearing seats 13, the longer stirring shaft 2 can rotate reliably, thereby reliably driving the stirring rod 22 to rotate, thus achieving continuous and stable stirring of the material.

[0028] The stirring rod 22 is formed by bending a square rod, and an electric heating wire 220 is installed inside the stirring rod 22 for heating the material. The square shape of the stirring rod 22 can improve the disturbance effect on the material, thereby improving the stirring effect. Furthermore, since the electric heating wire 220 is installed inside the stirring rod 22, it can heat the material, thereby causing the remaining moisture in the material to vaporize and be discharged from the feed pipe 11, significantly improving the dehydration effect of the material.

[0029] Several stirring rods 22 are spaced apart on the outer wall of the stirring shaft 2. The material wraps around the stirring rods 22, which ensures that all the heat generated by the heating wire 220 can be absorbed by the material, thereby improving the heating efficiency of the material.

[0030] The outer wall of the stirring shaft 2 is also provided with several water absorption mechanisms 4, which are arranged one-to-one on the outside of several stirring rods 22. The absorption mechanism includes a base 41, a water absorption plate 42 and a locking block 43. The base 41 is welded to the stirring shaft 2. The top of the base 41 is provided with a through groove 411, which extends along the length of the base 41. The water absorption plate 42 is inserted into the through groove 411. One side of the water absorption plate 42 is in contact with the stirring rod 22, and the other side of the water absorption plate 42 is in contact with the locking block 43. The locking block 43 is connected to the base 41 by bolts 44. The locking block 43 is provided with a through hole 430, which passes through the locking block 43 vertically. The bottom of the through groove 411 is provided with a threaded hole 412. When the locking block 43, the water absorption plate 42 and the stirring rod 22 are in a state of sequential contact, the through hole 430 and the threaded hole 412 are in a coaxial state, and the bolt 44 passes through the through hole 430 and is screwed into the threaded hole 412.

[0031] During the rotation of the stirring shaft 2, the suction plate 42 also rotates. Material can pass through the stirring rod 22 but cannot pass through the suction plate 42, maximizing the disturbance and mixing effect on the material. Furthermore, after removing the locking block 43, the suction plate 42 can be quickly removed from the through groove 411, facilitating replacement of the suction plate 42. The through groove 411 can be... Figure 2The straight-face type shown in the figure achieves axial and radial fixation of the water-absorbing plate 42 through the friction between the locking block 43 and the water-absorbing plate 42. It can also be a dovetail type. When it is a dovetail type, the through groove 411 itself can provide radial fixation of the water-absorbing plate 42 that is adapted to it, and then axial fixation is achieved through the locking block 43.

[0032] The above embodiments are merely preferred embodiments of this application and should not be construed as limiting the scope of protection of this application. Any non-substantial changes and substitutions made by those skilled in the art based on this application shall fall within the scope of protection claimed by this application.
