Continuous straw crushing system

Abstract

The present invention discloses a continuous straw crushing system, which sequentially comprises a material feeding system, a pre-powder system, an impurity removing system, a fine powder system, and a material storage system along a material operation direction, wherein the impurity removing system is connected with the pre-powder system and the fine powder system, the material feeding system comprises a chain plate conveyor, a first-stage leveling grille, a second-stage leveling grille and a material turning roller, the pre-powder system is provided with a leveling device arranged at the foremost end, a first-stage coarse powder device and a second-stage coarse powder device, the cutter shaft of the leveling device is provided with a vibration detector, an impurity removing grille is arranged above the rear of the leveling device, the impurity removing system comprises a crushed stone removing device and an iron remover positioned on the rear portion, the fine power system is provided with two crushing bins, the material inlet position is provided with a quantification roller, and a row of material separation rollers are arranged on the lower portion of the quantification roller. With the continuous straw crushing system of the present invention, the continuous and efficient crushing operation can be performed on straws, the problems of high impurity content in straws and large material feeding operation strength are solved, the crushing efficiency is high, the operation is safe and stable, and the large-batch and continuous production requirement can be met.

Description

technical field [0001] The invention belongs to the technical field of straw crushing, and in particular relates to a large-scale continuous straw crushing system. technical background [0002] The use of crop straw as biomass energy is becoming more and more extensive. Due to the special physical characteristics of straw, it is difficult for the existing material crushing process to crush it effectively. At the same time, due to the special storage and transportation environment, the straw contains impurities. The characteristics of high efficiency and large impurity volume, the impurity removal effect directly affects the service life of the equipment. The existing straw crushing process is mostly single-machine crushing, which has low output, high equipment failure rate, and heavy feeding operation intensity, which cannot adapt to large-scale production. Contents of the invention [0003] According to the deficiencies in the prior art above, the technical problem to be...
