Innovative Design of Dryer in Utilization and Disposal of Livestock and Poultry Manure

Abstract

With the rapid development of large-scale and intensive livestock and poultry farming, a large number of livestock and poultry manure has been produced. If livestock and poultry manure is directly stacked or improperly disposed of, it will cause extremely serious pollution to the surrounding water, air and soil, and endanger human health. It is an effective method to dispose and utilize livestock and poultry manure properly according to local conditions. However, because of the large water content of livestock and poultry manure, most of the water in the manure needs to be removed before resource disposal. Therefore, drying livestock and poultry manure is a necessary link in the resource disposal and utilization of livestock and poultry manure. In view of the shortcoming of high energy consumption, uneven drying and low drying efficiency existing in the existing drying technology equipment for livestock and poultry manure, on the basis of overall design and working principle analysis of the livestock and poultry manure dryer, innovative designs are made in the following aspects: improving the efficiency of material transportation from the sloping spiral feeding device; at the bottom of the feed box, seepage holes are equipped with, which can preliminarily filter and separate the moisture in livestock and poultry manure; the conveyor belt in the drying oven adopts three-step jump conveyor mode to realize the rolling conveyor drying of livestock and poultry manure. These innovative designs can improve the transportation efficiency, drying uniformity and drying efficiency of livestock and poultry manure, effectively reduce the moisture content in livestock and poultry manure, reduce the energy consumption of dryer, and effectively realize the resource disposal and utilization of livestock and poultry manure.
