NOVELTY - A system of whole sealing sludge roller device, comprises air inlet electrical valve, oxygen supplying fan, central controller, cyclone dust collector, biological deodorizer, temperature inductive and oxygen concentration inductive probes, sludge fermenting roller frequency conversion motor and solar energy fermenting shed. The signal receiving end of controller receives monitoring data of temperature and oxygen concentration inductive probes. The signal output of controller is connected with air inlet electrical valve, discharging electrical valve, fan and frequency conversion motor.    USE - As deodorizing, oxygen supplying and heat preservation system of whole sealing sludge roller device for preparing fertilizer (claimed).    ADVANTAGE - The deodorizing and oxygen supplying system realizes aerobic fermentation in the roller as well as environmental protection of fermenting device, where the environmental protection of the sludge roller fermenting device is combined with temperature control, oxygen supply, drying, automation of devices and other process factors via engineering technology, thus realizing treatment and protection of malodorous gas of engineering technology and preventing the environment from being polluted. The environmental protection preventive treatment of the sludge roller fermenting device is combined with the process factors of temperature control, drying and heat preservation, which obviously reduces odor and oxygen supply generated in the process of sludge composting and fermenting, provides environment-friendly solid waste harmless treatment, enhances work efficiency and has favorable practical applicability and market promotion value.    DETAILED DESCRIPTION - A deodorizing, oxygen supplying and heat preservation system of whole sealing sludge roller device for preparing fertilizer, comprises an air inlet electrical valve, an oxygen supplying fan, a central controller, a cyclone dust collector, a biological deodorizer, a temperature inductive probe and an oxygen concentration inductive probe, a sludge fermenting roller frequency conversion motor and a solar energy fermenting shed. The air inlet electrical valve is connected with the air inlet of the sludge roller fermenting device via a flange. One end of the fan inlet is connected with the air outlet of the sludge roller fermenting device via a flange via a pipe. One end of the fan outlet is connected with the cyclone dust collector and biological deodorizer via a pipe. The signal receiving end of the central controller receives the monitoring data of the temperature inductive probe and oxygen concentration inductive probe. The signal output of the central controller is connected with the air inlet electrical operated valve, discharging electrical valve, oxygen supplying fan and the frequency conversion motor of the sludge roller fermenting device. The solar energy fermenting shed is arranged between the feed bin and the discharging bin of the roller fermenting device and seals the fermenting section of the roller device.
