Problems solved by technology

[0007] At present, there are a lot of organic fertilizer fermentation equipment, but their common problem is that the fermentation time is too long, usually accompanied by a biogas generation device, which occupies a large area and the equipment structure is complex
Therefore, it is difficult to popularize, and agricultural wastes in rural areas are still mainly incinerated or discarded randomly, causing great pollution to the environment

Embodiment 1

[0027] After the raw materials such as livestock and poultry manure and crop stalks are prepared according to a certain ratio by using normal temperature fermentation strains, the raw materials are fed from the lower end of the feed port, and the speed of the screw agitator is set to 120r / min. The raw materials are gradually lifted from the bottom of the cylinder from the center to the top, and then scattered in an umbrella shape, and then returned to the bottom, so that the raw materials are rolled and stirred up and down in the cylinder, and a large amount of raw materials can be evenly mixed in a short time. After the specified fermentation time is over, open the lower outlet, reversely rotate the stirring shaft, and export the fermented organic fertilizer.

Embodiment 2

[0029] Select fermentation strains with a suitable temperature of 80-100°C, prepare livestock and poultry manure, crop straw and other raw materials according to a certain ratio, and feed them from the lower end of the feed port. After setting the speed of the screw agitator to 80r / min, use the motor Drive the rapid rotation of the spiral agitator to gradually lift the raw materials from the bottom of the cylinder from the center to the top, and then scatter them in an umbrella shape, and then return to the bottom, so that the raw materials are rolled up and down in the cylinder, and a large amount of raw materials can be evenly mixed in a short time. The mixing is complete. After the material is fed to the designated position, the hot air heating is turned on, and the air enters the heating air pipe to be heated and then sent into the cylinder; at the same time, the jacket heater is turned on. According to the measurement results of the temperature probes distributed outside ...

Embodiment 3

[0031]Select the fermentation strain whose fermentation temperature needs to be controlled at about 85°C. After preparing raw materials such as livestock and poultry manure and crop stalks according to a certain ratio, feed the material from the lower end of the feed port. After setting the speed of the screw agitator at 10r / min, use The motor drives the fast rotation of the spiral agitator to gradually lift the raw materials from the bottom of the cylinder from the center to the top, and then scatter them in an umbrella shape, and then return to the bottom. The mixing is complete. After the material is fed to the designated position, the hot air heating is turned on, and the air enters the heating air pipe to be heated and then sent into the cylinder; at the same time, the jacket heater is turned on. According to the measurement results of the temperature probes distributed outside the cylinder, the electric control box controls the temperature inside the cylinder to 85°C. Th...

Abstract

The invention relates to a composite heating fast fermentation device of an organic fertilizer. The composite heating fast fermentation device comprises a tube body and a spiral stirrer, wherein the tube body is provided with a material feeding opening and a material discharging opening. The composite heating fast fermentation device is characterized in that the tube body is a vertical diameter change tube body; a heating sandwich sleeve is arranged on the outer wall of the tube body; a sandwich heater is arranged on the heating sandwich sleeve; the material feeding opening and the material discharging opening of the tube body are formed in the bottom of the tube body; a ventilation pipeline communicating with an inner cavity of the tube body is arranged on the lower part side wall of the tube body; a heating air pipe is arranged on the ventilation pipeline. The composite heating fast fermentation device has the beneficial effects that a composite heating mode is used; the heat resource is increased; through hot air input into the inside, and the heating sandwich sleeve of the tube body, heating is simultaneously performed, so that the heat transfer can be accelerated; the heat efficiency is higher; in addition, during the hot air introduction into the tube body, the hot air per se has kinetic energy, so that the materials can be further promoted to be uniformly mixed; the hot air heating is used; during the heating, additional oxygen can be provided for fermentation thalli; the fermentation process is accelerated.

Description

technical field [0001] The invention belongs to the field of organic fertilizer processing, and in particular relates to a compound heating rapid fermentation device for organic fertilizer. Background technique [0002] my country is the country with the largest output of agricultural waste. Livestock and poultry manure, crop straw, etc. have not been effectively utilized for a long time. Livestock and poultry manure can easily cause soil and groundwater pollution, and crop straw burning is one of the main causes of atmospheric smog pollution. The ineffective use of agricultural waste has caused environmental pollution on the one hand, and land poverty has become increasingly serious on the other hand. Agricultural waste such as livestock and poultry manure and crop straw can be produced into various organic fertilizers through a series of processes. These processes include: mixing, ventilating, turning, post-ripening, drying, etc. Sufficient stirring during the fermenta...
