Description

Technical Field

[0001] The invention belongs to the technical field of feeding devices, and in particular relates to a feeding device used for a straw high-temperature anaerobic fermentation reactor. Background Art

[0002] The feeding requirements of straw high temperature anaerobic fermentation reactor are relatively high. The straw needs to be crushed first. After crushing, the specific surface area is large, which is conducive to the full action of microorganisms and can improve the fermentation efficiency. It is advisable to maintain a certain humidity of the straw. Usually, the moisture content of 60%-70% is more appropriate. Too high or too low humidity is not conducive to fermentation. When feeding, the crushed straw with appropriate humidity enters the reactor through the conveying equipment, where it can be better mixed with other materials evenly, ensuring that the fermentation reaction can be carried out evenly, thereby promoting the smooth progress of the entire high temperature anaerobic fermentation process.

[0003] The existing straw high-temperature anaerobic fermentation reactor can feed materials to ensure humidity loading as follows: First, accurately measure the moisture content of the straw before feeding. If it is too wet, air it out. If it is too dry, spray water appropriately to adjust it to the appropriate humidity range (60%-70%). Secondly, use a sealed delivery pipeline to prevent water loss or external water vapor from mixing in, and keep the humidity stable. A humidity monitor can also be installed in the pipeline for real-time monitoring. If the humidity deviates, it can be adjusted in time by means of water replenishment or ventilation and dehumidification through the spray device in the pipeline to ensure that the humidity of the straw fed into the reactor meets the standard and the fermentation proceeds smoothly. However, the above operation method is complicated, time-consuming and labor-intensive, so it needs to be improved. Summary of the invention
