Hardening and tempering stirring kettle for mariculture solid waste and hardening and tempering method

Abstract

The invention relates to a hardening and tempering stirring kettle for mariculture solid waste and a hardening and tempering method. The hardening and tempering stirring kettle comprises a kettle body; a feeding pipe is arranged on the kettle body; the kettle body comprises a conical cavity, a stirring drainage assembly is arranged at the bottom of the conical cavity, and a power assembly provides rotation power for the stirring drainage assembly; a discharging assembly is arranged on the kettle body; an end opening of the discharging assembly is connected to the wall of the conical cavity in a sealed mode; an air heater assembly and a water supply assembly are further arranged, and an air supply end opening of the air heater assembly and a water supply end opening of the water supply assembly are communicated with an inner cavity of the kettle body; and the stirring drainage assembly comprises a stirring impeller and a spherical filter cap, a wheel shaft of the stirring impeller is a hollow shaft, the spherical filter cap is mounted at an upper port of the wheel shaft, and a lower port of the wheel shaft is connected with a sewer line arranged at the bottom of the kettle body. The process and the device are used for performing dehydration and desalination treatment on the mariculture solid waste, the speed is high, and the mode is flexible. Small amount of testing is carried out, and after parameters are adjusted, automatic operation can be carried out.

Description

technical field [0001] The invention relates to the technical field of a breeding solid waste treatment process and device, in particular to a conditioning stirring tank and conditioning method for mariculture solid waste. Background technique [0002] At present, the total salt content of mariculture solid waste is much higher than that of livestock and poultry breeding solid waste. If such a high salt content is directly aerobic fermentation / aerobic composting, it will limit the microbial activity and cannot start the fermentation process. Therefore, desalination first, and then The process of fermentation. [0003] At present, dehydration and desalination by physical methods are more effective than using desalination agents, because desalination agents will greatly reduce the pH, and follow-up tests have found that they also inhibit microbial activity, and dehydration can remove part of the salt, and then add wheat straw and microbial agents. Normal fermentation. In ord...

Problems solved by technology

Use the inclined scraper to dewater while lifting the sludge. Because this method leads to high water content after dehydration, it cannot meet the requirements of some specific working conditions; using the method of draining water through the mesh screen, it can be partially dewatered with the assistance of vibration. , the water content is still not low, and it is often found that the mesh is blocked at the bottom due to the heavy mud and the water is still on the top; the water content can be well controlled by using the auger for dehydration, but it requires a large supporting power
