Claims10
A composting device, comprising a stirring device, a conveyor belt and a decomposing device, wherein the stirring device, the conveyor belt and the decomposing device are connected successively, wherein
- the stirring device comprises a support and a cylinder block, wherein the support and the cylinder block are fixedly connected;
- a spiral stirring mechanism and a humidity sensor are arranged in the cylinder block, the spiral stirring mechanism is connected to a motor, a liquid feeding device communicated with the cylinder block is arranged on the cylinder block, a first discharge port is formed at a lower portion of the cylinder block, and the first discharge port is arranged at a first end of the conveyor belt;
- the decomposing device comprises a reaction tank and a fixed support, wherein the reaction tank and the fixed support are fixedly connected;
- a stirring mechanism, an oxygen content sensor and a temperature sensor are arranged in the reaction tank, the stirring mechanism is connected to the motor, a water filling port and an eluting device are arranged at an upper portion of the reaction tank, a water draining port and a second discharge port are formed at a lower portion of the reaction tank, the reaction tank is communicated with an aeration system through an oxygen supply port, and a feeding port of the reaction tank is formed at a second end of the conveyor belt.
A composting method, comprising the following steps:
- step A:
- putting to-be-treated livestock and poultry manure and crushed straws in a cylinder block of a stirring device, covering a stirring mechanism with a lid, starting a spiral stirring mechanism driven by a motor, adding wood vinegar and enough distilled water through a liquid feeding device, and stopping water injection when a humidity sensor detects that a water content of materials reaches 60%, and keeping stirring until a mixture is uniform;
- step B:
- delivering the materials in step A to a reaction tank via a conveyor belt through a discharge port, keeping an oxygen concentration at not lower than 2.0% vol, and stirring the mixture by the stirring mechanism until the materials are decomposed;
- and
- step C:
- injecting a heavy metal eluent through a water filling port, eluting passivated heavy metals out by rotation of an eluting device, eluting the mixture, leaving the mixture still and turning the mixture out through the discharge port to complete composting.
