Anti-liquid-channeling high-temperature-resisting filtering device

Abstract

The invention discloses an anti-liquid-channeling high-temperature-resisting filtering device. The filtering device is formed by a barrel cover, a barrel body, an oil inlet pipe opening at the upper part of one side of the barrel body, an oil outlet pipe opening at the lower part of one side of the barrel body, a filtering net tray and a metal filtering net assembly, wherein the filtering net tray and the metal filtering net assembly are placed inside the barrel body; a high-temperature sealing gasket is mounted between the convex edges of the filtering net tray and the metal filtering net assembly; a force application device formed by a lower bowl-shaped sleeve of a compressed spring, the compressed spring and an upper bowl-shaped sleeve of the compressed spring vertically acts on the convex edge of the metal filtering net assembly, so that an upper cavity and a lower cavity of the barrel body are in sealed separation; a maintenance oil discharging opening is formed in the upper part of the barrel body; and all the components of the filtering device are prepared from stainless steel or carbon steel metal materials. The anti-liquid-channeling high-temperature-resisting filtering device disclosed by the invention can be ensure no liquid channeling in a filtering process and can resist a high temperature of 400 DEG C, and has the advantages of safety and convenience in a maintenance process, convenience for popularization and application, and the like.

Description

technical field [0001] The invention relates to a filter device, in particular to a liquid channeling-proof high-temperature-resistant filter device in the fields of hydraulic pressure, thermal engineering, chemical industry and the like. Background technique [0002] With the continuous expansion of the application fields of heat transfer fluid and heat transfer oil, the upper limit of the use temperature is getting higher and higher. In some closed systems, the use temperature of heat transfer oil is close to 350 ° C ~ 400 ° C. However, high temperature resistant filter devices that meet this temperature have not been developed simultaneously. At the same time, the traditional technology has no good solution to the common problem of channeling in barrel filter devices. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an anti-channeling liquid high-temperature resistant filter device, which can not only withstan...
