Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary devices for metal heat treatment, and in particular to a quenching oil filtration device for a heat treatment furnace. Background Technology

[0002] Quenching oil is a commonly used process oil in heat treatment, serving as a quenching medium. Heat treatment refers to a metal hot working process in which materials, in a solid state, are heated, held at temperature, and cooled to obtain the desired microstructure and properties. Quenching oil is used in heat treatment for quenching alloy steels and small-section carbon steels, achieving satisfactory hardenability and hardenability while preventing cracking and reducing deformation. However, the carbon black and oxide scale produced over long-term use act as adsorbents, absorbing additives from the quenching oil and accelerating its deterioration. Therefore, regularly removing carbon black and oxide scale is crucial for the maintenance of the quenching oil.

[0003] The Chinese Patent Network discloses a quenching oil filtration device for a heat treatment furnace, with the reference number "CNCN221693278". This device includes a filtration mechanism and an adjustment mechanism. The filtration mechanism comprises a filter box with an installation cavity at the top. A microfiltration membrane is installed inside the filter box. The adjustment mechanism includes a hopper installed in the installation cavity and capable of rotation within it. A discharge pipe, L-shaped, is connected to the bottom outlet of the hopper. Several through holes are located below the horizontal section of the discharge pipe. A base is mounted on the outside of the filter box, and a motor is mounted on the top of the base. The motor's output is connected to the hopper. The rotating hopper drives the discharge pipe to rotate, allowing the quenching oil to flow evenly onto the microfiltration membrane, thus improving its utilization rate. However, during rotation, the quenching oil is easily splashed onto the inner wall by centrifugal force, making it difficult to clean and potentially damaging the filter box over time.
