Abstract

The utility model discloses a biomass fuel fabrication device, comprising a hard straw chopper and a sawdust press, both in parallel arrangement. A roller with a blade is arranged behind a charging machine of the hard straw chopper; a sieve is arranged under the roller at an oblique angle; the lower end of the sieve is connected with a discharging machine; a sawdust storage tank is arranged under the sieve; a charging baffle is arranged above the charging machine and connected with a compactor; the compactor is positioned before the roller; the charging machine of the sawdust press is connected with a charging hopper; a press is connected with the lower of the charging hopper; a chute is provided to connect with the discharging machine; the press is connected with a motor; a heater is arranged outside the press and a mould at the bottom of the press. The biomass fuel fabrication device can machine the twiggy branches in the tree into the fuels for the power plant, when the by-product chippings and sawdust are mixed with the by-product sawdust from the wood processing plant to fabricate the wood fuel for the power plant. The biomass fuel fabrication has the advantages of simple process, low cost and investment, resource saving and wide application.

Description

A kind of biomass fuel preparation facilities

Technical field

The utility model relates to a kind of fuel preparation plant, particularly relates to a kind of biomass fuel preparation facilities.

Background technology

Method for the biomass fuel preparation mainly contains following several at present:

(1) Chinese patent application number is: 200510017492.6, and patent is by name: the processing of fuel of biomass for generating electricity and application method.This method is to comprise agricultural crop straw, forest logging residue and biomass such as forestry industrial wood waste, human and animal excreta and domestic waste, through Air drying, pulverizing, sieving separating, adding water stirs, being compressed into diameter with chilling press then is 8-10mm, length is the high density granular of 10-12mm, promptly gets fuel of biomass for generating electricity.The biomass fuel that makes can be directly used in the industrial boilers and the circular fluid bed of middle-size and small-size thermal power plant, when being used for coal-powder boiler, needs to adopt coal and this fuel mix to mix burning.This scheme add water and two programs of coldmoulding are defective, in the production of reality, lose more than gain, be difficult to realize.

(2) Chinese patent application number is: 200710186469.9, and patent is by name: biomass fuel forming method.This invention belongs to a kind of biomass fuel forming method, is characterized in: processed from strand by following component preparation, its main ingredient distribution of weight is as follows: stalk 20～95, starch 2～60.Its technological process of production comprises crushed stalk, sieves, starch hydrolysis, system paste, be mixed, moulding, drying process.This complex manufacturing, facility investment is big, and the cost height causes bigger disadvantageous effect to economic benefit.

(3) Chinese patent application number is: 200710013240.5, and patent is by name: a kind of cotton stalk biomass granular fuel and production method.It is formed through mechanical workout by cotton bavin powder, cotton tankage slag and sawdust, and production method comprises steps such as cotton bavin is cut off, pulverized, batching, material loading, slaking, moulding.This complex process, facility investment is big, and the cost height does not possess generalization.

The utility model content

In order to address the above problem, the utility model provides a kind of biomass fuel preparation facilities, is used for the preparation of biomass fuels such as trees withe bar and wood chip.

The technical solution of the utility model is: a kind of biomass fuel preparation facilities, comprise the hard stalk knife mill and the wood chip briquetting press that are arranged in juxtaposition, switch through drum behind the charger of hard stalk knife mill, blade is housed on the rotary drum, the rotary drum below is obliquely installed sieve, and the sieve low side connects discharging machine; The charger of wood chip briquetting press connects hopper, and the hopper below connects swager, divides into chute, connect discharging machine, it is characterized in that the hard stalk knife mill is provided with a charging baffle plate along the charger top, connects compactor, before compactor was positioned at rotary drum, the sieve below was provided with a wood chip storage tank; The swager of wood chip briquetting press connects a motor, the outside having heaters of swager, and there is template the bottom surface.The wood chip briquetting press can after mixing by a certain percentage, be processed into the required wooden unit fuel of power plant with the byproduct wood chip of the undersized small shreds of hard stalk knife mill, wood chip and various wood-working factories.

Usefulness of the present utility model is, hard stalk knife mill and wood chip briquetting press are united use, after the processing of trees withe bar is become the required withe bar fuel of power plant, its byproduct fine grained chippings and wood chip, with after the byproduct wood chip of wood-working factory mixes according to a certain percentage, also can be made into the required wooden unit fuel of power plant, have that technology is simple, cost is low, less investment and the characteristics that economize on resources, have very strong generalization.

Fig. 2 is a hard stalk knife mill structural representation;

Fig. 3 is a wood chip briquetting press structural representation.

Embodiment

Below in conjunction with accompanying drawing the utility model is further described.

Be illustrated in figure 1 as the schema of biomass fuel preparation facilities.With water ratio be 30%～45%, diameter is about 20 millimeters biomass materials such as trees withe bar raw material 17, in field seasoning 18, treat that its water ratio drops at 10%～15% o'clock, again it is sent into hard Straw cutting machine 19 chopping processing, withe bar raw material is processed into withe bar fuel 20 by the hard stalk knife mill, offers biomass fermentation power plant 21.The fine grained chippings wood chip 22 that processing produces mixes 24 by a certain percentage with timber mill wood raw material 23, can be processed into wooden unit fuel 26 with wood chip briquetting press 25.

Be illustrated in figure 2 as the structural representation of hard stalk knife mill.The withe bar raw material of trees is carried by the charger 1 of hard stalk knife mill earlier, enters compactor 3 compactings through charging baffle plate 2, sends rotary drum 4 again to, and the blade 5 on the rotary drum is fallen the raw material chopping on the sieve 6 then.Branch fuel after the chopping is after the screening effect, and the screen overflow material is power plant's required withe bar fuel, directly transfer out through discharging machine 7, and the small shreds of undersize material and wood chip, store wood chip storage tank 8 the insides that enter the bottom, is used for the processing of wooden unit fuel.

Be illustrated in figure 3 as the structural representation of wood chip briquetting press.The fine grained chippings that sieves from the hard stalk crusher, wood chip mix according to a certain percentage with the wood chip of wood-working factory, deliver to hopper 10 through the charger 9 of wood chip briquetting press earlier, enter the swager 11 of feed hopper bottom again.At swager 11 outer setting having heaters 16, the bottom is provided with motor 15 and template 12.Wood raw material elder generation heater via 16 thermoplastics that mix, pass through again under the driving effect of motor 15,, under action of gravity, pass through chute 13 landings to discharging machine 14 from 12 one-tenth certain block extrusion of template, wooden unit fuel behind naturally cooling is transported to the power station again.
