Abstract
Description
Technical Field
[0001] This utility model relates to a graphite electrode impregnation and protective material filtration device with a vertical flow structure. Background Technology
[0002] Graphite electrodes are prone to reacting with oxygen at high temperatures, leading to surface oxidation and peeling, which shortens their service life. Impregnation treatment can form a dense protective film on the surface of the graphite electrode, which isolates oxygen from direct contact with the graphite matrix and significantly improves its oxidation resistance. The impregnating agent fills the pores and microcracks inside the graphite, which can also improve the density and overall strength of the electrode and reduce damage caused by thermal stress or mechanical vibration.
[0003] Patent document CN117960489B discloses an impregnation device for producing graphite electrodes, which includes a base, an installation mechanism on the base, an impregnation tank connected to the installation mechanism, the impregnation tank being a hollow cylinder, and a first installation hole and a second installation hole coaxially opened at both ends of the impregnation tank. The first installation hole is connected to the installation mechanism, which is used to horizontally install the impregnation tank. The second installation hole is connected to an impregnation mechanism, which is connected to a grinding mechanism for grinding the surface of the graphite electrode. The impregnation mechanism includes a flow divider, a drive assembly, and an installation assembly. Multiple flow dividers are evenly distributed and fixedly installed on the inner sidewall of the impregnation tank. The sidewall of the flow divider in the width direction is fixedly connected to the inner end wall of the impregnation tank. The drive assembly is connected to the impregnation tank and is used to drive the impregnation tank to rotate. The installation assembly is connected to the second installation hole.
[0004] During the impregnation process, residual catalysts, solvents, or additives in the impregnating agent raw materials, metal particles from equipment wear, pipe corrosion products, dust from the operating environment, contamination from packaging materials, and degradation products of the impregnating agent caused by temperature fluctuations can clog the molecular chains or pores of the impregnating agent. This leads to increased viscosity, decreased fluidity, and difficulty in uniformly penetrating the impregnating agent into the micropores and cracks of the graphite electrode, resulting in localized dry areas or insufficient penetration, thus reducing the densification effect. Therefore, it is necessary to design a filtration device for this impregnation apparatus to ensure the purity of the impregnating agent and improve the impregnation effect. Utility Model Content

[0027] The secondary filtering components include:
[0028] The secondary filter cartridge has an inverted conical structure and is installed on the top of the receiving tank. Its inner cavity is connected to the drain pipe.

[0033] The advantages of this utility model are:
[0034] This filtration device features a conical primary filter and an inverted conical secondary filter, positioned above the primary filter to create a vertical flow structure. The inclined inner wall of the conical primary filter allows impurities intercepted during filtration to fall off under gravity, preventing accumulation and clogging on the filter surface, ensuring unobstructed filtration channels, and extending filter life. Similarly, the inclined outer wall of the inverted conical secondary filter allows intercepted impurities to fall off under gravity, preventing retention on the filter surface, reducing obstruction to the flow channel, and ensuring smooth discharge of filtered material. The vertical arrangement of the primary and secondary filter cartridges creates a direct flow path as the impregnated protective material flows upwards, reducing turbulence and dead zones between the cartridges, lowering fluid resistance, and improving conveying efficiency. The vertical flow structure ensures stable pressure after primary filtration, minimizes pressure loss during secondary filtration, and reduces overall energy consumption, thus improving filtration efficiency.
