Combined biomass breaking machine

Abstract

The invention discloses a combined biomass breaking machine which comprises a charging device, a discharging device, a breaking device and a feeding device, wherein the breaking device comprises a rotor main shaft, rotor cutter disks, fly cutters, cutter pins and a filter net; the rotor cutter disks are arranged and fixed on the rotor main shaft at an equal interval; the multiple groups of fly cutters are connected with the rotor cutter disks through the cutter pins; gaps are formed between the flying cutters and the filter net; a discharging hole is formed below the filter net and connected with the discharging device; the feeding device comprises an upper pressure roller and a lower pressure roller which form a feeding channel adopting an L-shaped structure; one end of the feeding channel, provided with a larger opening, faces to a feeding hole and is connected with the charging device, and the other end of the feeding channel is connected with the breaking device; the lower pressure roller comprises feeding rollers arranged in parallel and is connected with a charging conveying belt; the upper pressure roller at least comprises a feeding roller and is mounted on an upper pressure roller cover; a hinge is arranged at the feeding hole end of the pressure roller cover. The combined biomass breaking machine has the advantages of simple structure, suitability for breaking various biomass fuels, high breaking efficiency, stability, smaller product particle size and the like.

Description

Technical field [0001] The invention relates to the development fields of biomass power generation, gasification, and papermaking, in particular to a biomass raw material crusher. Background technique [0002] In biomass power generation, biomass gasification, and papermaking industries, the crushing process of biomass raw materials is complicated and energy consumption is high. The drum knife-cutting crusher commonly used at present can only be crushed on a small scale by manual feeding. The efficiency is low, and the foreign matter mixed in the fuel such as stones and iron blocks can easily impact the rotor and cause equipment damage. The hammer mill crusher has low crushing stability, high energy consumption, and poor crushing effect on flexible biomass materials. Summary of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a crusher with simple structure, high crushing efficiency, low maintenance cost, and ...
