Poultry excrement drying device

Abstract

The invention discloses a poultry excrement drying device. The device comprises a hot-blast stove, a feeding mechanism, a stirring and grinding device, a separating column, a discharging mechanism, a fan and a dust recovery device, wherein the hot-blast stove is used to provide hot blast; the feeding mechanism is used to feed poultry excrement; the stirring and grinding device can scatter and grind the poultry excrement entering the shell of the device; the separating column is used to separate the poultry excrement from air flow; the discharging mechanism is arranged at a discharge hole on the lower end of the separating column and used for discharging; the fan is arranged in a pipe between the separating column and the dust recovery device and used to generate air flow along the hot-blast stove, the stirring and grinding device, the separating column and the dust recovery device; and the dust recovery device is used for air-out and dust recovery. The poultry excrement drying device has the advantages of fast processing speed, good dewatering effect and deodorizing effect, high nutrient retention capacity, good sterilizing effect, high degree of grinding, uniform fineness, no environmental pollution and the like. The technology is especially suitable for the pretreatment of poultry excrement feed preparation and is especially suitable to be used in the poultry farm.

Description

technical field [0001] The invention relates to a poultry manure drying equipment which can be used for drying poultry manure. Background technique [0002] All large-scale mechanized poultry farms will face a more important problem, namely how to deal with poultry manure. According to statistics, a poultry discharges about 100 grams of wet poultry manure on average every day, and a mechanized poultry farm that raises 300,000 poultry can discharge up to 30 tons of wet poultry manure every day. A large amount of wet poultry manure not only provides a breeding ground for the growth of pathogenic bacteria and maggots, but also the stench emitted can reduce the egg production rate of poultry. Traditional poultry manure treatment is generally used for fertilizer, its utilization rate is relatively low, and poultry farmers are not interested, so many poultry farms will cause poultry manure to accumulate, and its odor, waste water, etc. will cause serious environmental pollution p...
