Project Description
Vaccum Furnace is suitable for cleaning the polymer materials filters and strainers, making them be reused after calcination, and saving the production cost. It is also a kind of environmental protection equipment.
The Vaccum Furnace applied the characteristics that polymer can be melted at a certain temperature, decomposed under the condiction of high temperature around 300℃ and isolating from air, and complete oxidation when above 400℃ and a little oxygen and certain vacuum degree. Using this characteristics, we first heat the cleaned pieces to the melting temperature, meiting the high polymer on the surface of filters and let them flow down into the waste collecting tank. At this time, surface of the filters remians only a little high polymer and ash content, when the furnace temperature rose up to the cracking temperature ( can according to technological requirements ), open the vacuum pump, lead to a small amount of air to the rest of high polymers, they will be completely oxidation and can get carbon dioxide and water, through the suction of water-ring vacuum pump, the carbon dioxide and water vapour generated in furnace are washed by the spray washer, and then discharged out the furnace.
