Embodiment Construction

[0027] The specific implementation of a composite biomass crusher will be described in detail below with reference to the drawings.

[0028] Such as Figure 1 to 6 As shown, a composite biomass crusher includes a feeding device 9, a discharging device 11, a crushing device 1, and a feeding device 2. The crushing device 1 includes a rotor main shaft 17, a rotor cutter head 12, and a flying knife 13. , Knife pin 7, filter screen 20, rotor cutter head 12 and other gaps are arranged and fixed on the rotor spindle 17, multiple groups of flying knives 13 are connected to the rotor cutter head 12 through the knife pins 7, and the flying knives 13 are on the adjacent rotor cutter head 12. A pin sleeve 29 is added to limit the position. Driven by the rotor power device 10, the rotor cutter head 12 rotates at a high speed, and the flying knife 13 rotates at a high speed with the axis of the rotor main shaft 17 as the center to generate centrifugal force. The flying knife 13 and the filter ...

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 ...
