AI Technical Summary

Technical Problem

Existing biomass pellet mills lack auxiliary feeding and mixing structures, which makes it easy for raw materials to get clogged at the connection between the feed hopper and the pelleting chamber. In addition, raw materials with high moisture content tend to stick to the inner wall of the feed hopper, making feeding difficult. After pelleting, the high moisture content makes it difficult to maintain a stable shape.

Method used

An auxiliary feeding assembly, including a spiral auger and a stirring rod, is installed in the feed hopper to push and stir the raw materials and prevent blockage. An auxiliary drying assembly is installed during the feeding process to dry the particles and remove excess moisture using a drying fan and heating tube.

Benefits of technology

It effectively prevents raw material blockage, ensures continuous and stable feeding, improves feeding efficiency, and stabilizes the pellets through drying, thereby enhancing the quality and stability of biomass pellets.

Abstract

The utility model discloses an anti-blocking pellet press for biomass pellet processing, which belongs to the technical field of biomass pellet processing, and adopts the technical scheme that the anti-blocking pellet press comprises a pellet press body, the pellet press body comprises a base, a driving part, a pellet pressing chamber, a feeding hopper and a discharging shell, an auxiliary feeding assembly is arranged in an inner cavity of the feeding hopper, and the driving part is arranged on the base; the problems that an existing pellet press for biomass pellet processing is generally lack of an auxiliary feeding and stirring structure, after biomass raw materials enter a feeding hopper, the raw materials are prone to being accumulated and blocked at the joint of the feeding hopper and a pellet pressing cavity, the raw materials are difficult to smoothly enter the pellet pressing cavity for pellet pressing operation, and the pellet pressing efficiency is low are solved. In the prior art, biomass raw materials with large humidity are easy to adhere to the inner wall of a feed hopper, the feeding difficulty is further intensified, and the existing pellet press lacks an auxiliary drying structure in the blanking link, so that the biomass particles are difficult to maintain stable shapes if the humidity is large after the biomass particles are pressed and formed.
