The invention discloses a drum-type sludge drying device. The drum-type sludge drying device comprises a hot air furnace, a stirring drum, a first driving mechanism, a second driving mechanism, a dust remover and a heat exchanger, wherein the second driving mechanism comprises a stirring shaft and a second driving motor; the stirring shaft is connected with an output shaft of the second driving motor; the stirring shaft is capable of simultaneously doing autorotation and doing circular motion around a shaft axis in the stirring drum; a plurality of stirring wings are arranged on the stirring shaft at intervals; a plurality of lifting plates orientated to the axis are arranged on the inner wall of the stirring drum at intervals. The drum-type sludge drying device is simple in structure and low in production cost; the stirring shaft is arranged inside the stirring drum and is capable of simultaneously doing autorotation and doing circular motion, so that the sludge stirring efficiency is improved; a plurality of small holes are formed in the lifting plates, so that the sludge mixing effect is improved, the drying rate is also increased, and energy conservation and emission reduction are facilitated; the inner structure of the dust remover is optimized; the dust remover is combined with a check valve and a copper net, so that the dust removing efficiency is obviously improved.
Description
technical field [0001] The invention relates to a sludge drying device, in particular to a drum type sludge drying device with a built-in stirring function. Background technique [0002] In recent years, the Chinese government has attached great importance to sewage treatment, and has increased capital investment and treatment efforts in sewage treatment. The number of sewage treatment plants has begun to increase rapidly, and the scale is also expanding. With the continuous determination and implementation of national environmental protection plans and the realization of national environmental protection goals year by year, my country has made rapid breakthroughs and developments in urban sewage treatment and industrial wastewater treatment. [0003] However, the more perfect the wastewater treatment is, the more sludge will be generated, and the problem of safe and cheap sludge treatment and disposal has become increasingly prominent, which has become a major problem for e...
