detailed description

The utility model is set forth below according to the embodiment shown in the accompanying drawings. It can be thought that embodiment disclosed this time is an illustration in every point, and is not restrictive. The scope of the present invention is not limited by the description of the following embodiments, but is shown by the scope of the claims, and includes the same meaning as the scope of the claims and all modifications within the scope of the claims.

The utility model relates to a pulping pretreatment device for biomass waste, which comprises a pulping bin 5 , a pulp storage bin 12 and a sorting bin 6 . Among them, the pulping bin 5 is used for pulping the biomass waste, the pulp storage bin 12 is used for storing the pulped material after pulping treatment, and the sorting bin 6 is used for pushing and discharging the solid matter in the waste. The pulping chamber 5 is cylindrical and is installed in the horizontal direction. The lower part has a liquid outlet hole for the pulping material to pass through. One side of the cylinder in the direction of the central axis is provided with a feed port 1. The feed port 1 is connected to the pulp through the bolt 2. The shells of the chemical chamber 5 are connected, and the other side of the cylinder is connected with the sorting chamber 6. A rotatable rotating shaft 4 is arranged on the central axis of the pulping chamber 5, and bearings 8 are arranged at both ends of the rotating shaft 4, so that the rotating shaft 4 can rotate around the central axis of the pulping chamber 5, and a shock absorber 9 and a motor are arranged at one end thereof. 10. The shock absorber 9 is used to slow down the impact and vibration generated during the pulping process, and the motor 10 provides the power for the rotation of the rotating shaft 4 . Blades 3 are arranged along the spiral direction on the rotating shaft 4 , and the rotation of the blades 3 along the rotating shaft 4 can crush the material in the pulping bin 5 and move from the feeding port 1 side to the sorting bin 6 side.
