AI Technical Summary

Technical Problem

Traditional pulverizing equipment has low pulverizing efficiency and poor grading accuracy for composite carbon source biomass raw materials, and is prone to equipment blockage, failing to meet the particle size requirements of different application scenarios.

Method used

The system employs a combination of crushing rollers, hammers, and a transmission assembly with a screen plate. The raw materials are guided by a material guide assembly, initially crushed by the crushing rollers, then finely crushed by the hammers, and finally screened by the screen plate. The transmission assembly reduces the rotational speed and increases the torque to prevent clogging.

Benefits of technology

It improves the crushing efficiency, realizes the efficient graded crushing of composite carbon source biomass raw materials, avoids equipment blockage, and meets the particle size requirements of different application scenarios.

Abstract

The utility model relates to the technical field of biomass treatment, and discloses a composite carbon source biomass raw material crushing and grading device which comprises a crushing box, a crushing roller pair is rotationally arranged in the crushing box, a first horizontal gear is fixedly arranged at one end of the crushing roller pair, the crushing roller pair is in transmission connection with a rotating shaft, and a second horizontal gear is fixedly arranged at the other end of the crushing roller pair. A plurality of hammer heads are hinged to the rotating shaft, a motor for driving the rotating shaft is fixedly arranged on one side of the crushing box, and an output shaft of the motor is connected with a transmission assembly for conducting transmission between the rotating shaft and the crushing roller pairs. Input raw materials can be guided through the material guiding assembly, large raw materials can be preliminarily crushed through the crushing roller pair, the raw materials can fall down after being preliminarily crushed, the rotating shaft can drive the hammer head to quickly rotate, and the raw materials can be finely crushed, so that graded crushing of the composite carbon source biomass raw materials can be realized, and the crushing efficiency is improved.
