Description

Technical Field

[0001] This utility model relates to the field of insulating oil production technology, specifically to an insulating oil reactor with a self-cleaning component. Background Technology

[0002] An insulating oil reactor is a specialized reaction device for processing or producing insulating oils (such as transformer oil and cable oil). Its core function is to synthesize, refine, or modify insulating oils by controlling reaction conditions (such as temperature, pressure, and agitation). Insulating oils must be prepared under high-purity conditions. The reactor's airtight design prevents external impurities (such as moisture and oxygen) from entering, avoiding oil oxidation or performance degradation. High-voltage design meets the requirements of processes such as hydrogenation and degassing, for example, removing sulfides or moisture during transformer oil refining. The synthesis or modification of insulating oils often requires a specific temperature range. The reactor uses a jacket or coil to circulate heat transfer oil, steam, or other media to achieve uniform heating or cooling. This prevents localized overheating that could lead to oil cracking or additive failure, ensuring stable insulation performance. A stirrer ensures thorough mixing of additives and insulating oil, preventing stratification or uneven concentration.

[0003] Traditional insulating oil reactors have shortcomings in use. First, they lack a self-cleaning component capable of cleaning the inner wall of the reactor. Second, for reactors with integrated spiral coils, they cannot promptly scrape off the oil from the spiral coils to prevent localized overheating. Therefore, optimization and improvement are necessary. Summary of the Invention

[0004] The purpose of this invention is to overcome the aforementioned problems in traditional technologies and provide an insulating oil reactor with a self-cleaning component.

[0005] To achieve the above-mentioned technical objectives and effects, this utility model is implemented through the following technical solution: An insulating oil reactor with a self-cleaning component includes a reactor body, an agitator, an oil inlet pipe, and an additive inlet pipe installed at the upper end of the reactor body, a discharge pipe installed at the bottom end of the reactor body, a jacket installed on the outer side of the reactor body, a spiral protrusion tube for improving the heating effect provided in the tube section of the reactor body located inside the jacket, and a self-cleaning component installed inside the reactor body for continuously scraping the oil on the spiral protrusion tube. The self-cleaning assembly includes a rotary drive, an annular mounting plate, a telescopic straightening tube, a lifting push rod, a hanging rod, an auxiliary stirring plate, and a flexible scraper. The fixed outer ring of the rotary bearing in the rotary drive is fixed to the inner wall of the reactor body. The moving inner ring of the rotary bearing in the rotary drive is mounted with a lifting push rod via the annular mounting plate. The movable end of the lifting push rod is connected to the auxiliary stirring plate via the hanging rod. A telescopic straightening tube is installed between the top of the auxiliary stirring plate and the annular mounting plate. A flexible scraper is installed on the side end of the auxiliary stirring plate. The flexible scraper has a row of concave scraping grooves that cooperate with the spiral convex tube.

[0006] Furthermore, in the aforementioned insulating oil reactor with self-cleaning components, an inlet medium pipe is installed on the upper outer side of the jacket, and an outlet medium pipe is installed on the lower outer side of the jacket.

[0007] Furthermore, in the aforementioned insulating oil reactor with self-cleaning components, the jacket is provided with a spiral guide plate for extending the flow path of the medium, and the pitch of the spiral guide plate is matched with the pitch of the spiral convex tube.

[0008] Furthermore, in the aforementioned insulating oil reactor with self-cleaning components, the cross-section of the spiral convex tube is semi-circular.

[0009] Furthermore, in the aforementioned insulating oil reactor with self-cleaning components, the telescopic straightening tube is composed of an upper tube and a lower tube that slides and is confined within it. The outer end of the upper tube is fixed to an annular mounting plate, and the outer end of the lower tube is fixed to an auxiliary stirring plate.

[0010] Furthermore, in the aforementioned insulating oil reactor with self-cleaning components, the auxiliary stirring plate is provided with through holes that reduce resistance and improve shearing effect.

[0011] Furthermore, in the aforementioned insulating oil reactor with self-cleaning components, the flexible scraper is made of a wear-resistant rubber sheet.

[0012] Furthermore, in the aforementioned insulating oil reactor with a self-cleaning assembly, the lifting push rod can reciprocate up and down, and the stroke of a single displacement is equal to the pitch of the spiral convex tube.

[0013] The beneficial effects of this utility model are: This utility model has a reasonable structural design. For the reactor body with spiral convex tubes that improve the heating effect of the jacket, a self-cleaning component is added inside the reactor body. The self-cleaning component includes a rotary driver, an annular mounting plate, a telescopic straightening tube, a lifting push rod, a hanging rod, an auxiliary stirring plate, and a flexible scraper. The rotary driver drives the auxiliary stirring plate and the flexible scraper to rotate circumferentially. The rotation of the auxiliary stirring plate achieves auxiliary stirring. The lifting push rod drives the flexible scraper to rise and fall during the circumferential rotation, so that the flexible scraper can adapt to the direction of the spiral convex tube, meeting the requirements of self-cleaning and preventing local overheating.

[0014] Of course, any product implementing this utility model does not necessarily need to achieve all of the above advantages at the same time. Attached Figure Description
