Description

Technical Field

[0001] The utility model relates to the technical field of vegetable insulating oil refining equipment, in particular to a large-scale refining device for vegetable insulating oil for transformers. Background Art

[0002] Vegetable insulating oil is a high-ignition-point, environmentally friendly, renewable liquid insulating material. Its main component is triglyceride fatty acid esters, which are derived from vegetable oils such as soybean oil, tea seed oil, and rapeseed oil. After being refined by a refining device, vegetable insulating oil can replace mineral insulating oil, avoiding the large amount of CO2 emissions generated by the treatment process and treatment products after the end of the life of mineral insulating oil. At the same time, the temperature and pressure required for vegetable insulating oil in the production process are lower than those of mineral oil, and the energy consumption is relatively low, which further reduces CO2 emissions. In addition, vegetable insulating oil also has the advantages of high ignition point, environmental friendliness, and high natural degradation rate. It can be widely used in oil-immersed insulation high-voltage equipment, such as oil-immersed transformers, etc., and is particularly suitable for power stations in urban core areas with high environmental protection requirements.

[0003] The bulk refining device of vegetable insulating oil for transformer is a kind of equipment specially used for refining vegetable insulating oil to meet the demand of transformer use; the main purpose of the device is to refine the vegetable insulating oil to the performance standard that meets the requirements of transformer through a series of process steps; the refining device usually includes a reactor body, which is equipped with a variety of mixing and heating devices.

[0004] However, existing refining devices may have deficiencies in mixing, resulting in uneven mixing of the oil; this not only affects the refining effect, but may also cause the performance of the oil to fail to meet the expected standards. Heating is another important step in the refining process, which is used to remove impurities and moisture in the oil; however, the heating device of the existing refining device may be fixed and single, resulting in low heating efficiency and uneven heating; this not only prolongs the refining time, but also may cause unstable quality of the oil. Utility Model Content

[0005] The purpose of the utility model is to provide a large-scale refining device for vegetable insulating oil for transformers in order to solve the problems that the existing refining device may have deficiencies in mixing, resulting in uneven mixing of oil materials, and the heating device of the existing refining device may be fixed and single, resulting in low heating efficiency and unstable oil quality.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a large-scale refining device for vegetable insulating oil for transformers; comprising a reaction barrel, a heating ring is fixedly installed in the inner wall of the reaction barrel, a motor is fixedly installed at the bottom of the reaction barrel, a transmission rod is fixedly connected to the output end of the motor, a plurality of groups of stirring rods are arranged on the outer side of the transmission rod, the transmission rod is hollow, a heating rod is arranged in the transmission rod, a driving gear is rotatably connected to the bottom of the reaction barrel, a belt is arranged between the driving gear and the output end of the motor, a transmission gear is arranged on the outer side of the transmission rod, the diameter of the transmission gear is larger than that of the driving gear, the transmission gear is meshed with the driving gear, a stirring block is fixedly installed on the top of the transmission gear, and a fan blade is arranged on the stirring block;

[0007] As a further solution of the utility model: a top cover is provided on the top of the reaction barrel, a feed inlet is provided on the top cover, and a discharge port used in conjunction with the feed inlet is provided on one side of the bottom of the reaction barrel, and a plurality of support legs are fixedly installed on the bottom of the reaction barrel;

[0008] As a further solution of the utility model: the top of the transmission rod is rotatably connected with a rotating block, one side of the rotating block is fixedly installed with an air inlet, and a cavity for cooperating with the heating rod is opened in the transmission rod;

[0009] As a further solution of the utility model: a convex block is provided at the bottom of the rotating block, a slide groove used to cooperate with the convex block is provided at the top of the transmission rod, the heating rod movably passes through the rotating block, the transmission rod movably passes through the top cover, and a plurality of nozzles used to cooperate with the air inlet are fixedly installed on the stirring rod;

[0010] As a further solution of the utility model: a fixed block is fixedly installed on the top cover, the rotating block is located inside the fixed block, and the air inlet passes through the fixed block.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. By setting a motor to drive the transmission rod, the stirring rod can be rotated quickly in the reaction barrel, so as to achieve the mixing of the liquid in the reaction barrel. At the same time, through the cooperation between the belt, the driving gear and the transmission gear, the stirring block can be driven to rotate in the reaction barrel. The driving gear is smaller than the transmission gear, so the rotation speed of the stirring block is smaller than the rotation speed of the transmission rod, and the rotation directions of the stirring block and the transmission rod are opposite. This structure is convenient for better mixing of liquids, reducing mixing time and improving working effects. Secondly, through the fan blades in the stirring block, the liquid in the reaction barrel can be rotated while rotating, so as to achieve the effect of disturbing the liquid in the barrel. Through the cooperation between the heating ring of the reaction barrel and the heating rod in the transmission rod, the liquid in the reaction barrel is mixed more evenly, the quality of the oil is more stable, and the practicality and working efficiency of the entire large-scale refining device of vegetable insulating oil for transformers are improved;

[0013] 2. By setting the mutual cooperation between the protrusion and the slide groove, when the transmission rod rotates, it will not drive the air inlet to rotate synchronously. When the transmission rod moves through the top cover, the transmission rod will not be affected by the top cover. Secondly, the gas in the transmission rod can be sprayed out through the nozzle. When the stirring rod rotates in the reaction barrel to mix the liquid, the continuous spraying of gas can enhance the disturbance effect of the liquid, thereby improving the reaction efficiency. Secondly, when the gas is stored in the transmission rod, it will be affected by the heating rod, which will increase the temperature of the gas. When the gas is mixed into the liquid, the mixing efficiency between the liquids can be accelerated. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Please refer to Figure 1-Figure 7When in use, the transmission rod 15 is driven by the motor 3 to make the stirring rod 9 rotate rapidly in the reaction barrel 1, so as to achieve the mixing of the liquid in the reaction barrel 1. At the same time, the belt 14 cooperates with the driving gear 11 and the transmission gear 10 to drive the stirring block 12 to rotate in the reaction barrel 1. The driving gear 11 is smaller than the transmission gear 10, so the rotation speed of the stirring block 12 is smaller than the rotation speed of the transmission rod 15, and the rotation directions of the stirring block 12 and the transmission rod 15 are opposite. This structure is convenient for better mixing of liquids, reducing mixing time and improving working effects. Secondly, the fan blades 13 in the stirring block 12 can rotate while the liquid in the reaction barrel 1 is rotating, so as to achieve the effect of disturbing the liquid in the barrel. The heating ring 8 of the reaction barrel 1 and the heating rod 6 in the transmission rod 15 cooperate with each other, so that the liquid in the reaction barrel 1 is mixed more evenly, the quality of the oil is more stable, and the practicality and working efficiency of the entire large-scale refining device of vegetable insulating oil for transformers are improved.
