Abstract

The present invention relates to a high-vacuity rectangular vacuum cracking cleaning furnace. It contains vertical furnace cavity, furnace body, furnace cover, heating element and waste material collecting tank. The vertical furnace cavity is communicated with waste material collecting tank. Said invention also provides the concrete structure of the vertical furnace cavity, furnace body and furnace cover. After the invention is adopted, when the internal high temperature makes the furnace cavity produce deformation, the furnace mouth can not be deformed so as to fully ensure vacuity of furnace interior.

Description

Technical field: [0001] The invention relates to a vacuum cleaning furnace, in particular to a rectangular vacuum cracking and cleaning furnace suitable for cleaning chemical fiber polymers attached to parts such as spinnerets and distribution plates of super-large components in the chemical fiber industry. Background technique: [0002] Existing vacuum cleaning furnace, as the patent No. is the disclosed vacuum cleaning furnace technical scheme of the Chinese patent of 96218124.2, contains vertical hearth, furnace body, furnace cover, heating element, waste material collection tank, and vertical furnace hearth communicates with waste material collection tank. Since the furnace is subjected to high temperature above 500°C and also bears vacuum negative pressure, the furnace mouth is deformed after being heated and expanded, and the vacuum degree in the furnace cannot be fully guaranteed. Invention content: [0003] The purpose of the present invention is to overcome the de...
