Abstract
The invention discloses a vacuum incinerator. The vacuum incinerator is a JZK-C well type vacuum incinerator and comprises a vacuum hearth, an incinerator cover opening and closing device, electric heating pipes, a waste collecting system, a vacuum pipeline anti-blocking device, a water spraying device, a water ring vacuum pump, a water backflow preventing device, a gas-water separator, a control system, a water circuit, an air circuit and the like, wherein the vacuum hearth is horizontally placed with an incinerator opening facing upwards and composed of an incinerator cover and a work room used for storing cleaned parts. The waste collecting system mainly comprises a waste collecting tank which is installed on the lower portion of the hearth. A hopper-shaped tray is arranged at the bottom of an inner cavity of the vacuum hearth. A discharging port of the tray is located over the waste collecting tank. Compared with the prior art, the vacuum incinerator is compact in structure, good in sealing performance and large in work space; the incinerator cover is opened and closed through two oil cylinders, the cover opening angle is larger than 90 degrees, and the opening and closing stability of the incinerator cover is guaranteed; waste can be collected conveniently, incineration and cleaning are conducted efficiently, and the situation of water backflow can be effectively prevented; and the automation level is high, temperature control is accurate, the working efficiency is improved, and the labor intensity is relieved.
Description
technical field [0001] The invention relates to the field of vacuum incineration, in particular to a vacuum incinerator device suitable for cleaning chemical fiber polymers attached to components such as spinnerets and distribution plates of super-large components in the chemical fiber industry and a method for incineration using the device . Background technique [0002] The vacuum incinerator 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 dies in the plastics, cable, and resin industries. The vacuum incinerator 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 t...
