Description

Technical Field

[0001] This utility model relates to the field of epoxy insulation material preparation technology, and in particular to an epoxy insulation material mixing device that is easy to clean. Background Technology

[0002] Epoxy insulation components, as core parts of power equipment responsible for electrical insulation and mechanical support, are based on epoxy resin and their performance is optimized through composite design. Epoxy resin itself possesses excellent adhesion, chemical stability, and electrical insulation properties; however, pure resin is relatively brittle after curing, requiring the addition of curing agents such as acid anhydrides and amines to form a three-dimensional cross-linked structure to enhance toughness. To further improve material performance, fillers such as micron-sized silica and high thermal conductivity boron nitride are introduced into the system, which can reduce shrinkage, improve heat resistance, and impart special functions such as flame retardancy and thermal conductivity. In addition, the addition of coupling agents can improve the interfacial compatibility between the filler and the resin, reducing defect generation. With the development of power equipment towards higher voltage and miniaturization, epoxy insulation materials are evolving towards higher purity, lower dielectric loss, and resistance to partial discharge, placing higher demands on the batch stability and impurity control of raw materials.

[0003] Bearing housings, as supporting and positioning components for bearings, play a crucial role in mechanical equipment. Their technological background is closely linked to bearings, aiming to provide a stable and reliable mounting environment. Bearing housings typically consist of a housing body, a cover plate, and fasteners. The housing body is internally designed with precise holes and bosses for mounting and securing the bearing. Depending on different application requirements, bearing housings come in various forms and specifications, such as split bearing housings, integral bearing housings, and bearing housings with adjustment functions. During the manufacturing process, the selection of materials, machining precision, and surface treatment of the bearing housing are all critical to ensure that it meets the operational requirements of the equipment and provides sufficient rigidity and stability.

[0004] Patent document CN222450960U discloses a mixing device for producing high thermal conductivity insulating epoxy molding compound. This invention solves the problem of difficulty in cleaning the mixture adhering to the inner wall after mixing. This invention uses a fan and a silicone brush. After the mixture is mixed, the can lid is opened, and the connecting rod is installed at the center of gear B. The motor is started, rotating the stirring shaft, which in turn drives gear B via gear A, causing the connecting rod to rotate. Because of the residual heat inside the can after mixing, a micro-fan accelerates air circulation, quickly drying the mixture adhering to the inner wall of the can. The dried residue is then scraped off with a silicone brush. Because the adhesive force of the molding compound residue decreases after drying, it is more likely to become independent solid particles and detach from the surface more easily, thus allowing for more thorough removal.

[0005] As in the prior art of the aforementioned patent, the tank lid needs to be opened for cleaning. However, most reaction vessels in the prior art are usually not openable. In the prior art, special organic solvents are generally used, such as acetone, butanone (MEK), and methyl ethyl ketone for uncured epoxy resin, and hot alkaline solutions or organic amine solvents for cured epoxy resin. Furthermore, the stirring rod and tank wall inside the mixing tank will have residual raw materials that need to be cleaned. However, if the raw materials are cleaned by filling the entire reaction vessel with cleaning solvent, the cost is high and the efficiency is slow. There is a need for a mixing reaction device that can easily clean the raw materials inside the tank. Utility Model Content

[0023] To make the technical solution of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

Two water spray pipes 22 are installed inside the reaction vessel 3, and multiple annular pipes 20 are installed on each water spray pipe 22. Fan-shaped high-pressure nozzles 21 are connected to the multiple annular pipes 20. The stirring motor 4 of the stirring assembly, through an electronic control device, rotates the stirring rod 17 and scraper 18 to their initial positions, parallel to the positions of the multiple fan-shaped high-pressure nozzles 21. The solvent for cleaning the reaction vessel 3 enters each annular pipe 20 through the water spray pipes 22. The solvent inside the annular pipes 20 is sprayed out through the fan-shaped high-pressure nozzles 21, cleaning the stirring rod 17 and scraper 18, removing residual raw material solution from the pipe walls, scraped by the scraper 18, and on the stirring rod 17. The solution is then discharged through a waste output pipe 14, thus achieving cleaning of the inside of the reaction vessel 3.

[0025] As a preferred embodiment, the stirring assembly includes a stirring motor 4 fixedly installed at the top of the reactor 3.
