The invention discloses a vacuum pipe washing device of a vacuum washing furnace. The vacuum pipe washing device comprises a vacuum pipe anti-blocking device, a spraying device and a control system, wherein the vacuum pipe anti-blocking device comprises a vacuum housing, a water ring type vacuum pump and a gas-water separator. The vacuum housing is fixed on a furnace body. The spraying device comprises a water spraying purifier and a backflow prevention device; the backflow prevention device comprises a normally closed solenoid valve arranged on a spraying tank and a manual inlet valve. The vacuum pipe anti-blocking device, the spraying device and the control system are connected. The control system is provided with interlinked temperature controllers comprising procedure temperature control and capable of giving alarms at low water pressure, over temperature and low vacuum. During vacuumizing, the vacuum pipe washing device effectively solves the problem of vacuum pipe blocking, and prevents water from flowing back to the vacuum device. The control system can accurately control the heating temperature and improves accuracy and efficiency.
Description
technical field [0001] The invention relates to the field of vacuum cleaning, in particular to a vacuum pipeline cleaning device for a vacuum cleaning furnace suitable for cleaning chemical fiber polymers attached to components such as spinnerets and distribution plates of super-large components in the chemical fiber industry. Background technique [0002] The vacuum cleaning furnace is suitable for cleaning components, spinnerets, filter cores, etc. used in the production of polyester, nylon, polypropylene, and non-woven fabrics in the chemical fiber industry, and is also suitable for cleaning die heads in the plastics, cable, and resin industries. The vacuum cleaning furnace utilizes the characteristics that high molecular polymers can be melted at about 300°C, can be cracked and coked above 300°C without air, and can be completely oxidized above 400°C in an environment with a small amount of air and a certain degree of vacuum. The workpiece with polymer dirt is heated to ...
