Description

The sugarcane top disintegrating machine

Technical field

The utility model relates to a kind of grinding and processing raw material equipment, particularly is applied to the broken process equipment of biomass granule fuel of sugarcane top or mulberry tree branch.

Background technology

Sugarcane top is a kind of reproducible biomass energy, shortage exhaustion along with fossil energy, adopt reproducible biomass energy sources for generating electricity to cause common concern in the industry, China is large agricultural country, and particularly very large of the annual production of southern sugarcane, act as a fuel with sugarcane top, with low cost, cleanliness without any pollution, the fuel value of sugarcane top is high simultaneously, is a kind of desirable biomass energy.Adopt living beings to be generated electricity the raw material fragmentation as the important procedure of its pre-treatment, the granularity after fragmentation is to the subsequent handling important.The breaker that following several types is arranged in prior art.

1. the contact area when bar shaped rotary cutter of rotation multi roll disintegrating machine (Granted publication number is CN202172619U, CN2894240Y) cuts material is little, rotary inertia during rotation is little, the moment strength that the bulk foreign matter in sugarcane top is infiltrated in fragmentation as the sugarcane head is little, do not reach once or few number of times just can complete fragmentation, and want repeated multiple times fragmentation just can complete, the cutting crushing efficiency is obviously low.

2. single roller or multiple roll hang the disintegrating machine (Granted publication number is CN20235415U, CN2643637Y, CN202095311U, CN2870437Y) of cutter type, outstanding cutter adopts the form of Household kitch knife, reaping hook, the cutting edge of deleting cutter or saw blade cutting edge, although the knife edge very sharp the operation starting stage can be very fast the broken task of raw material that completes, but while along with the increase of the initial bulk of raw material and extensive style filler, causing large block foreign material to introduce, very easily cause the damage of blade, cause the reduction of whole work efficiency.

3. vertical type straw crusher (Granted publication number is CN202206758U), adopt crumbling method from top to down, raw material is dropped into by the top charging aperture, after the blade fragmentation of vertical distribution, get rid of, although be provided with tooth plate at the crushing bin inwall, but on tooth plate, do not have flow blocking strip to make the broken material can be along the drive of rotary cutter and clog-freely could not be cut off in time with the circulation moving, the time lengthening be cut, stock-removing efficiency reduces; And vertical structure is when infiltrating like this chopping of the bulk foreign matter in sugarcane top in the face of the sugarcane head; though hammer leaf protection in top is arranged but its protection effect is limited, if the bulk foreign matter fails can have a strong impact on the broken efficiency of cutting and broken mass effect in the top fragmentation.

In sum, the existing crusher of existing market, crushing effect is limited is crushing energy transmission capacity deficiency, knife edge structure very easily weares and teares, and single-revolution rotates the problems such as crushing efficiency is not high, the fragmentation that it just is applicable to stalk and peanut shell etc., be not suitable for the pulverizing requirement of southern area sugarcane top as the biomass grain forming fuel feedstocks, therefore prepares a kind of equipment that meets the broken requirement of sugarcane top grain forming biomass fuel and be necessary.
