Description

Feces drying device

technical field

The utility model relates to a drying device, in particular to a device for drying feces.

Background technique

Feces are the physiological excretions of the human digestive system and urinary system, which are rich in organic matter and nitrogen, phosphorus, and potassium components. They are traditional organic fertilizers and good soil regulators in my country's agriculture. If the organic matter and nitrogen, phosphorus and other substances of feces are directly discharged, it will cause water pollution and emit harmful gases containing odorous components such as ammonia, hydrogen sulfide, mercaptan, sulfide, etc. The patient's feces contain a variety of intestinal pathogenic bacteria, parasitic Insect eggs and viruses, 70% of diseases in developing countries are related to biological infection of feces. It is of great practical significance to dispose of feces in my country in accordance with the principles of reduction, harmlessness and resource utilization.
