Description

A kind of straw granulator

Technical field

The utility model relates to the agricultural crop straw processing equipment, relates more specifically to a kind of stalk particle manufacture method and uses the equipment of this method.

Background technology

Show that according to statistics in 2006 annual about 700,000,000 tons of the stalk that produces of China can be collected 4.5 hundred million tons of parts, at present comprehensive utilization ratio less than 10%.Along with the increasing of national environmental protection dynamics, the adjustment of rural energy structure, stalk life utilization rate reduces and rice wheat straw chemical pulping factory of a large amount of paper plant closes, and stalk utilization rate more greatly reduces, and stalk is handled problems more and more outstanding.Contain a large amount of nitrogen, phosphorus, potassium, hydrocarbon etc. in the stalk, and just the stalk moisture content of harvesting is higher, can not completing combustion, produce a large amount of flue dust that contains nitrogen oxide, sulfur dioxide etc. in the burning process, not only rural stmosphere has been caused serious pollution, even jeopardize adjacent city, and also can work the mischief when serious to land route and air route transportation, a lot of cities are reported repeatedly and are caused delayed situation thus.If, then powder of straw is processed into particle, can also can make many purposes such as general sorbing material, pad pet nest used as feed, as clean fuel with the existing pulverizing of stalk.Yet, also do not make the Perfected process of stalk particle and mechanical specially at present.

The utility model content

The purpose of this utility model provides the method for a kind of high efficiency processing stalk particle and makes in this way special machinery.

The utility model is achieved in that a kind of straw granulator; comprise frame, dynamical system, feed system, granulating system, discharging opening; it is characterized in that granulating system is to comprise along at least two the rotatable milling rollers of transmission shafts to symmetry; the periphery of milling roller motion circle upwards has a ring mould; one end of ring mould is fixed on the frame; big outer little bellmouth in the ring mould is directly upwards distributing; the periphery of ring mould has the grain-cutter of circumferential rotation; the periphery of grain-cutter has ring mould cover; the top of ring mould cover is connected to charging aperture, is connected to discharging opening below.

More specifically: the radially-outer surface of each milling roller is the male and female face of well word structure, the groove of the annular that upwards distributing in week in the ring mould, and this groove is corresponding with the convex surface of milling roller outer surface.

In order conveniently to regulate the spacing between milling roller and the ring mould inwall, to adapt to different types of stalk, also be useful on the turbine distance adjustor of regulating crack between milling roller and the ring mould internal perisporium, that is: all milling rollers are connected on the pernetti along center final drive shaft symmetry, pernetti and center final drive shaft are connected as a single entity, rotate with power transmission shaft, each milling roller is enclosed within respectively on the eccentric shaft, one end of eccentric shaft be embedded in above the pernetti eccentric shaft in the heart, the other end connects a turbine, turbine connects worm screw, and the two ends spindle nose of worm screw is connected on the pernetti by axle bed, and one of them spindle nose exposes axle bed and is square.During work, drive the worm screw rotation, pass through turbine with spanner rotation square toes

Stalk enters into interior all cavitys of ring mould through charging aperture, under the drive of milling roller, dynamically stalk is pressed into the radially-arranged bellmouth of ring mould, that encircles mould and milling roller in principle axially can be designed to various angles, but consider the layout that makes things convenient for of each parts such as transmission, generally can consider to make vertically or level.Consider the influence of gravity effect again, become vertical state better pressure roller and the axial design of encircling mould processing.

Grain-cutter and milling roller can use a power source jointly by power transmission shaft, drive, driving-belt separately, and power source can be common electric machine.

Consider and improve working (machining) efficiency and automation, charging aperture can external spiral positive feed device, and discharging opening connects conveyer belt, another termination drying unit of conveyer belt.Can work continuously like this and directly go out dry good stalk particle.

After considering that stalk enters into ring mold cavity space along charging aperture, because the effect of gravity is sunk, be connected with the stirring pawl that stirs stalk so be connected with scraper, the top on inclined-plane in the bottom of pernetti, rotate at milling roller like this and roll in the work, stalk is constantly stirred, dynamically evenly rolled, become the cylindricality particle into bellmouth.

Owing to adopt above-mentioned design, it is very simple, efficient to make that stalk is processed into the technology of cylindricality particle, thoroughly solved present because of the unspecial stalk particle equipment of producing, a difficult problem that can not the suitability for industrialized production stalk particle; Designed special machine tool is simple in structure, the working (machining) efficiency height.
