Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of pipeline conveying devices, in particular to an intelligent metering anti-blocking pipeline device for biogas slurry fertilization. BACKGROUND

[0002] In the process of manufacturing biogas slurry from straws, the process generally includes the following steps: straws, pretreatment (crushing + adjustment), anaerobic fermentation (core conversion), post-treatment (sedimentation + solid-liquid separation + purification), finished biogas slurry, etc. Finally, the finished biogas slurry is conveyed from the post-treatment equipment to the desired fertilization site by the cooperation of the conveying pipeline, the frequency conversion pump and the PLC intelligent controller (the frequency conversion pump is one of intelligent agricultural power machinery). With the development of technology, agriculture is gradually moving towards intelligence, and automatic control of flow and automatic alarm are important components of intelligent power machinery.

[0003] On the one hand, the existing device generally adopts a fertilization mode of "fixed flow + time estimation", that is, the total amount of fertilization is controlled by presetting the output flow and working time of the frequency conversion pump. However, the nutrient concentration of biogas slurry fluctuates due to factors such as fermentation raw materials and fermentation period. Under the condition of fixed flow, high concentration is easy to cause over-fertilization (soil salinization), and low concentration is easy to cause insufficient fertilization. On the other hand, the pipeline equipment of the existing device is directly connected with the post-treatment equipment. Biogas slurry contains complex components, such as small solid particles and fiber debris, which are not completely decomposed, and impurities, which are easy to cause blockage of the curved part of the pipeline, the valve and the metering component.
