Abstract

The invention relates to the technical field of anaerobic fermentation, in particular to a spiral extrusion feeding device which comprises a hollow shell, the shell is obliquely arranged relative to the horizontal plane, a motor is installed at the top of the shell, the output end of the motor is connected with a spiral shaft, a first spiral piece is arranged on the spiral shaft, the spiral shaft is located in the shell, and a feeding port and a discharging port are formed in the shell. The discharging port is positioned at the upper end of the feeding port; the spiral shaft is further provided with a second spiral piece, the spiral direction of the second spiral piece is opposite to that of the first spiral piece, and the joint of the first spiral piece and the second spiral piece is located at the discharging port. Due to the fact that the rotating direction of the second spiral piece at the discharging port is opposite to that of the first spiral piece, the materials can be prevented from being accumulated on the axial tail portion of the first spiral piece, the transmission torque of the first spiral piece is reduced, and the material conveying efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of anaerobic fermentation, in particular to a screw extrusion feeding device. Background technique [0002] Dry anaerobic fermentation technology is an ideal technology for organic waste disposal and resource utilization. It has positive effects in the disposal and utilization of livestock and poultry waste, agricultural straw, kitchen waste, etc., and the reduction of environmental pollution. effect. Dry anaerobic fermentation tank is the core equipment of dry anaerobic fermentation technology. In order to improve the disposal efficiency, it is often used to increase the solid content of the material, thereby increasing the volumetric gas production rate. When the solid content is greater than 20%, the material is basically in a solid state, which puts forward higher requirements for the feeding equipment that matches the fermenter. [0003] Existing organic wastes such as livestock and poultry waste, agr...
