High solid content material feed arrangement of biogas fermentation

The utility model discloses a high solid content material feed arrangement of biogas fermentation, coaxial continuous conveyor screw in proper order after in the past arriving, pressure boost spiral and ejection of compact spiral, on the screw axis of cutting knife suit between pressure boost spiral and ejection of compact spiral, the front end of conveyor screw screw axis stretches out that helical tube is external to be passed through the shaft coupling with the speed reducer and link to each other, be equipped with the feeder hopper on the anterior helical tube body of conveyor screw, set up the drainage hole on the helical tube body of the conveyor screw at feeder hopper rear, the external still cover of helical tube of the conveyor screw at feeder hopper rear is equipped with the urceolus, set up the raffinate discharge port on the urceolus, the tail end of ejection of compact spiral sets up the discharge gate. The utility model discloses a solved the high solid content of present biogas fermentation for the material pumping over to send easy jam, spiral to promote upper portion feeding structure complicated, problem with high costs. Area is little, simple structure, and the installation is nimble, and the maintenance cost is low.
