Agricultural waste straw fermentation device and fermentation method for shallow geothermal energy supply

Abstract

The invention discloses an agricultural waste straw fermentation device for shallow geothermal energy supply and a fermentation method.The agricultural waste straw fermentation device comprises a box body, a sealing plate is slidably mounted at the bottom of the side face of one end of the box body, rotating blocks are rotatably connected to the two ends of the surface of one side of the sealing plate, and threaded rods are rotatably mounted at one ends of the rotating blocks; threaded rings are fixedly connected to the two sides of the other end of the box body, the surface of one end of each threaded rod is in threaded connection to the side face of the corresponding threaded ring, a fixing ring is fixedly connected to the surface of one side of each threaded ring, a folding sleeve is fixedly connected to the surface of one side of each fixing ring, and the surface of one side of each folding sleeve is slidably connected to the surface of the corresponding threaded rod in a sleeving mode. And the surface of one end of the folding sleeve is fixedly connected to the side faces of the two ends of the sealing plate, a first hinge shaft is hinged to the surface of one end of the threaded rod, and a rotating rod is hinged to the surface of the first hinge shaft, so that use convenience and stability can be greatly improved, and safety and high efficiency of cleaning and maintenance are guaranteed.

Description

technical field [0001] The invention relates to the field of straw fermentation, and more specifically relates to an agricultural waste straw fermentation device and fermentation method for shallow geothermal energy supply. Background technique [0002] In the current agricultural production and management process, a large amount of agricultural straw will be produced. In order to ensure environmental safety and resource recovery rate, most of them are fermented through fermentation equipment, which can be used for heat energy supply and utilization. [0003] However, most of the existing straw fermentation devices are directly buried under the ground with a simple box body. Although this is good for positioning and sealing, as the fermentation is used, the internal sediments will increase, which is very unfavorable for cleaning. The device uses spiral blades to convey and discharge the material, which will also cause a large amount of residue inside, which will affect the s...

[0003] However, most of the existing straw fermentation devices are directly buried under the ground with a simple box body. Although this is good for positioning and sealing, as the fermentation is used, the internal sediments will increase, which is very unfavorable for cleaning. The device uses spiral blades to convey and discharge the material, which will also cause a large amount of residue inside, which will affect the subsequent fermentation and use, and the maintenance cost is high, which needs to be improved
