Abstract

The utility model provides a biomass fuel breaker, with better break effect, small broken fuel, high break speed and high efficiency. The utility model is characterized in composed of a material hopper, two parallel blade shafts respectively mounted on a frame, wherein two ends of the blade shaft via a coupler are respectively connected with a speed reducer, the speed reducer is connected with a relative motor, the two blade shafts are respectively sheathed by a blade disc, the blade discs on the two blade shafts are embedded with each other and axially offset, the blades are distributed along the circumference of the blade disc, the two blade shafts have reversal rotations, while nearby blades on the blade shafts are meshed when in rotation, the lower portion of the material hopper is connected with a material plate, and the material plate is guided into the mesh opening on the two blade discs of the two blade shafts.

Description

The biomass fuel disintegrating machine

(1) technical field

The utility model relates to the disintegrating apparatus of a kind of discarded object that is used for agricultural, production of forestry such as plant class such as straw, fruit tree branch and bark and culled wood, tailing etc., is specially the biomass fuel disintegrating machine.

(2) background technology

The discarded object waste wood bavin of the wastes straw of agricultural production, fruit tree branch and production of forestry, branch bar, bark etc. all are valuable biomass fuels, can be used as the fuel of boiler, after the boiler internal combustion, produce steam, are used for generating and heat supply.Biomass fuel is the reproducible energy, actively utilizes bio-fuel to substitute primary energy such as part oil, coal, for the consumption that reduces primary energy, reduce environmental pollution, increase farmers' income, obvious social and economic benefit is arranged.

Biomass fuel must carry out fragmentation before sending into boiler combustion.Biomass fuel after fragmentation can be sent into boiler smoothly, adopt crusher in crushing in the industry, the structure of disintegrating machine adopts a cutter shaft, motor must run up during broken material like this, and the single shaft fragmentation, it is mashed that a part of material is normally stirred, owing to be not the shearing between cutter and the cutter, so the crushing effect of material is undesirable, broken efficient is low.

(3) summary of the invention

At the problems referred to above, the utility model provides a kind of biomass fuel disintegrating machine, and its crushing effect is better, and the fuel size after the fragmentation is little, and broken speed is fast, and efficient is higher.

It is achieved through the following technical solutions: it is characterized in that: it comprises hopper, two cutter shafts that are arranged side by side, described cutter shaft is installed on support respectively, the two ends of described cutter shaft connect reductor respectively by shaft coupling respectively, described reductor is connected with the motor of respective end respectively, described two cutter shafts are respectively installed with cutterhead, described cutterhead on two cutter shafts embed mutually and axially dislocation arrange at interval, cutting knife is along the circumference of described cutterhead, described two cutter shaft direction of rotation, when two cutter shafts rotate on two cutter shafts adjacent cutting knife blade be and shear the interlock shape; The bottom of described hopper connects time flitch, and described time flitch imports the cutterhead articulation port of described two cutter shafts.

It is further characterized in that: described cutting knife is flush-mounted in described cutterhead and by trapezoidal wedge location, described trapezoidal wedge be positioned at described cutting knife front edge below, and be connected with screw between the described cutterhead; Described cutting knife is nail pick shape, and front edge has the inclination angle, and it is circular-arc that the knife back is parabola; Cutting knife is " eight " font shearing interlock shape in relative rotation; The position that described cutter shaft combines with cutterhead, the outline of described cutter shaft, the endoporus of cutterhead are hexangle type; Circumferential cutting knife cutting edge along cutter shaft is arranged as screw type.

In the said structure of the present utility model, two cutter shafts are realized THE ADIABATIC SHEAR IN between corresponding two cuttves when rotating, material can be shredded fast like this, and cutter shaft is provided with a plurality of cutterheads, and cutterhead is provided with many cutter, cutter shaft rotates a circle like this, just have many tool settings and realize shearing, so during broken material, broken speed is fast, efficient is higher, thereby avoided in the prior art, it adopts the single shaft stationary knife, the shortcoming that material is difficult for being broken.

(5) specific embodiment

See Fig. 1, the utility model comprises hopper 1, two cutter shafts 2 that are arranged side by side, cutter shaft 2 is installed on support 6 respectively, and (Fig. 1 is a front view, can only see a cutter shaft), the two ends of cutter shaft 2 connect reductor 7 respectively by shaft coupling respectively, and reductor 7 is connected with the motor 8 of respective end respectively, two cutter shafts 2 are respectively installed with cutterhead 3, cutterhead 3 on two cutter shafts 2 embed mutually and axially dislocation arrange (see figure 2) at interval, 13 is every dish, adjacent cutterhead is separated and plays positioning action to cutterhead.Cutting knife 4 is along the circumference of cutterhead 3, two cutter shaft 2 direction of rotation, when two cutter shafts 2 rotate on two cutter shafts 2 adjacent cutting knife 4 blades be and shear the interlock shape, the bottom of hopper 1 connects time flitch, time flitch imports cutterhead 3 articulation ports of two cutter shafts 2.See Fig. 3, cutting knife 4 is flush-mounted in cutterhead 3 and by trapezoidal wedge 11 location, trapezoidal wedge 11 be positioned at cutting knife 4 front edges below, and be connected with screw 12 between the cutterhead 3; See Fig. 4, cutting knife 4 is nail pick shape, and front edge 9 has the inclination angle, and it is circular-arc that the knife back 10 is parabola, and cutting knife 4 is " eight " font shearing interlock shape in relative rotation; The position that cutter shaft 2 combines with cutterhead 3, the endoporus of the outline of cutter shaft 2, cutterhead 3 is the hexangle type (see figure 3); Circumferential cutting knife 4 cutting edges along cutter shaft 2 are arranged as screw type.5 is material blocking block among Fig. 1.
