Heat storage type organic fertilizer preparation excrement drying line

Abstract

The invention discloses a heat storage type organic fertilizer preparation excrement drying line. The heat storage type organic fertilizer preparation excrement drying line comprises a track, a control system, a heat storage loop and a heat supply loop, the heat supply loop is a circulation loop formed by connecting a first heater and a heat exchanger through a pipeline, a heat exchange medium flows in the circulation loop, and a part of pipe section, positioned in front of the first heater, of the heat supply loop is a heating pipe arranged below the track. The heat storage loop is a circulation loop in which a heat-conducting medium flows and which is formed by sequentially connecting a heat exchanger, a second heater and a heat storage device in which a heat storage material is arranged through a pipeline; and a part of pipe section of the heat storage loop is used as a heat exchange pipe which is positioned in the heat storage device and in contact with the heat storage material. The power grid consumption reduction enterprise cost is reduced, the production cost is reduced, and the production efficiency is improved. The heating temperature is controlled through heating of the heating pipe, different drying temperatures and powers can be set so as to adapt to drying of different kinds of manure, accurate control over the drying process temperature is achieved, and the effects of effective sterilization and effective nutrient protection are achieved.

Description

technical field [0001] The invention relates to a dung drying line for preparing organic fertilizer, in particular to a heat storage drying line for preparing dung from organic fertilizer. Background technique [0002] In the process of raising chickens, the feed ingested by chickens is not completely digested and absorbed, and about 40-70% of the nutrients will be excreted from the body. There will be great harm and hidden dangers when it is directly applied to crops after treatment or decomposing: it is directly applied to the soil, fermented under suitable conditions and generates a lot of heat, which will burn the root system of the crops; chicken manure is used year after year, and it will remain in the soil. A large amount of sodium chloride salt causes abnormal plant growth, sparse flower buds, and fruit failure, which significantly restricts the improvement of crop yield and quality; chicken manure is a campsite and hotbed for root-knot nematodes, and for more than 3...

Problems solved by technology

However, since the energy of sunlight fluctuates greatly, and there is no effective means to regulate it, the control accuracy of the drying process is poor.
