Description

The biomass fuel comminutor

Technical field

The utility model provides the processing equipment of mechanical field, specifically the biomass fuel comminutor.

Background technology

At present, raising along with environmental protection and energy-conservation policy requirements, biomass fuel based on agricultural crop straw progressively comes into one's own, but because the stalk energy density under the nature is low, high volatility, opium big fire, burning are used all inconvenient, and waste is serious, so the compression stalk fuel is paid attention to by people.Stalk is after biomass granule fuel is made in overcompression, being convenient to transportation, keeping and burning utilizes, improved energy density relatively, its fuel value can be equal to coal, but be easy to burning and on fire than coal, and combust is low, sulfur content is low, and the ash content after the burning can also use in plant culture as trace-element fertilizer and potash fertilizer.

Before the utility model proposes, be raw material with byproducts such as agricultural crop straws, be biomass granule fuel through being a granulated into, be used for burning and obtain heat.According to the difference of design principle, mainly contain pair roller type and compression.Wherein the comminutor of pair roller type is that pair roller by relative motion rolls the particle that forms certain density and intensity through the stalk pulverized etc.Another kind is that compressed stalk is extruded from the type mouth by the continuously extruded stalk of screw mandrel, forms granular fuel.

Because the deficiency of project organization, compression process can not reach the output height, cost is low, is not easy to mechanization production, and maintenance management is also inconvenient.

Summary of the invention

In order to overcome the shortcoming of existing stalk compressor, the utility model provides a kind of biomass fuel comminutor.This machine is by setting up elevator and setting up pressure bearing and two rollers solve living beings and compress at a high speed and enhance productivity and simplify the technical problem of link on body.

The scheme that the utility model technical solution problem is taked is:

The spice machine arranged in that hopper one side of particle pressing machine is supporting, drive the axle rotation by the dynamo-electric machine of spice, on its axle, the material casting plate is installed, the material that is cooperated is thrown in the hopper, elevator is installed in hopper, be connected with elevator bucket on it, the upper end is connected with inlet orifice, and inlet orifice places the top of particle pressing machine feeding port and communicates with it; Particle pressing machine is installed on the support, and its motor and support are vertically fixing, and motor shaft is by fluted disc flower cover and governor engaged transmission; Governor is installed on the axle, and it passes a pair of concentric bearings respectively in two ends up and down, in the bottom of lower end concentric bearings pressure bearing is installed also; Be provided with the discharging chamber on governor top, the bottom of the axle in it is equipped with the material casting wheel, and rotary cutter apart is installed between top and the porous plate; Top in the discharging chamber is equipped with porous plate, which is provided with a plurality of binder holes that vertically communicate; Nip rolls connecting rod by right-angled intersection above porous plate is equipped with nip rolls, and the nip rolls of installing on each bar is two; On the upper shaft of nip rolls, paddle is installed.

Good effect is: owing to spice machine and elevator arranged in that body one side is supporting, and the reductor downside in body is equipped with pressure bearing, a plurality of running rollers are installed on axle simultaneously, therefore can replace the artificial material that promotes by enough mechanical lifting materials, prevent the active force that reductor is downward with pressure bearing, alleviate destruction, realize high-intensity compression with a plurality of running rollers to motor and other parts, make compacted density big, the compression efficiency height.The suitable compression with multiple biomass materials such as stalks used when granulation acts as a fuel.

Among the figure, 1. spice machine, the dynamo-electric machine of 1.1. spice, 1.2. material casting plate; 2. hopper, 3. elevator, 3.1. elevator bucket, 3.2. inlet orifice; 4. support, 5. particle pressing machine motor is 6. spool with motor connector, 7. governor; 7.1. concentric bearings, 7.2. pressure bearing, 8. grain export, 9. material casting wheel; 10. rotary cutter, 11. porous plates, 11.1. binder hole, 12. nip rolls; 12.1. the nip rolls connecting rod, 13. paddles, 14. feeding ports, 15. particle pressing machine axles.

The specific embodiment

Shown in Fig. 1～3, spice machine 1 arranged in that hopper 2 one sides of particle pressing machine are supporting, drive the axle rotation by the dynamo-electric machine 1.1 of spice, on its axle, material casting plate 1.2 is installed, the material that is cooperated is thrown in the hopper 2, elevator 3 is installed in hopper, be connected with elevator bucket 3.1 on it, the upper end is connected with inlet orifice 3.2, and inlet orifice places the top of particle pressing machine feeding port 14 and communicates with it; Particle pressing machine is installed on the support 4, and its motor and support are vertically fixing, and motor shaft is by fluted disc flower cover and governor engaged transmission; Governor is installed on the axle 15, and it passes a pair of concentric bearings 7.1 respectively in two ends up and down, in the bottom of lower end concentric bearings pressure bearing 7.2 is installed also; Be provided with the discharging chamber on governor top, the bottom of the axle in it is equipped with material casting wheel 9, and rotary cutter 10 apart is installed between top and the porous plate; On the top in discharging chamber porous plate 11 is installed, which is provided with a plurality of binder holes 11.1 that vertically communicate; Nip rolls connecting rod 12.1 by right-angled intersection above porous plate is equipped with nip rolls 12, and the nip rolls of installing on each bar is two; Paddle 13 is installed on the upper shaft of nip rolls.

Wherein, the power resources of elevator are dc speed-regulating motor, by the following chain roller mutually power connection of supporting reductor with elevator.

The effect of pressure bearing is to play the anti-effect that pushes away, thereby reduces the pressure effect and destroy motor and associated components.

The governor of installing in the body is a cycloid speed reducer.

The course of work of the present utility model

At first organic-biological raw materials such as stalk are pulverized, join then in the spice machine, when stirring, material dished out in the hopper, be subjected to the effect of elevator elevator bucket, it is risen in the inlet orifice, and dose in the feeding port, motor rotation at this moment, by the rotation of governor drive axle, and the drive paddle disperses and stirring the material that is added, constantly pressed the grain running roller to roll through the material that stirs, be squeezed in the binder hole, be subjected to follow-up the clamp-on push effect of material and the qualification effect in binder hole, form strip and from the binder hole, extend downwards, then, be subjected to the cutting action of rotary cutter, become bar-shapedly, arrive the wheel of dishing out, the centrifugal action of taking turns of being dished out is discharged from grain export, has realized the process of biomass material granulation.

Particle pressing machine of the present utility model is supporting the spice machine; material is evenly stirred, and be thrown in the hopper, have elevator that material is risen in the feeding port owing to supporting; by stirring, press grain, pelletizing, dishing out, form the biomass fuel pellet product then.And the dynamo-electric machine of spice, the supporting power motor of elevator all adopt dc speed-regulating motor, do not lack material so can guarantee particle pressing machine, do not swallow material, makes its normal operation, stops because feeding question causes the generation of particle pressing machine shutdown phenomenon.

Particle pressing machine of the present utility model can move continuously, has realized automatically, thereby has reduced artificial consumption, has reduced production cost.
