AI Technical Summary

Technical Problem

Existing biomass pretreatment devices have problems in the crushing and screening stages, such as uneven particle size, sieve hole blockage, imperfect circulation treatment, and high energy consumption, which affect the efficiency and safety of biomass direct combustion coupled power generation.

Method used

The machine adopts oblique and transverse sieve plate graded screening combined with claw hook circulating crushing mechanism. The biomass raw materials are crushed by the interlocking rotation of the crushing teeth. The large particles after screening are returned to the crushing bin by the claw hook for secondary crushing to ensure the uniformity of material particle size. Scraper cleaning and electric heating are used to prevent blockage and agglomeration.

Benefits of technology

It improves the crushing efficiency and material uniformity, enhances the operating stability of the device, reduces energy consumption and maintenance costs, and realizes efficient pretreatment of biomass raw materials.

Abstract

The utility model discloses a processing device for biomass direct-combustion coupling power generation, which relates to the field of biomass direct-combustion coupling power generation and comprises a crushing bin, a stock bin, a conveying piece and matched parts, the interior of the stock bin is divided into a feeding bin and a discharging bin through a transverse sieve plate, and the transverse sieve plate is connected with an inclined sieve plate to form a sieving channel; a conveying piece on the outer side of the crushing bin drives a claw hook to convey large-particle materials in the feeding bin back to the crushing bin, and the large-particle materials are matched with crushing teeth to achieve circulating crushing. And an electric heating wire is matched with a heat preservation layer, so that material caking is avoided. Through grading screening, directional circulation crushing and anti-blocking and anti-caking design, the device can efficiently complete biomass pretreatment, material uniformity and device stability are improved, energy consumption and maintenance cost are reduced, and the device is suitable for the direct-combustion coupling power generation pretreatment link of biomass such as wood and straw.
