The present invention can convey stalk effectively.
Description
Technical field
The present invention relates to a kind of method that straw power generation fuel is carried that solves, can be used for power plant, logistic storage, enterprise's transmission material, belong to the band conveyor technical field.
Background technology
Coal has accounted for 92% in China's energy reserves, and this has determined that China's energy production and consumption structure will be based on coals in quite long from now on period.Energy consumption structure based on coal has caused China's environment to be subjected to gross pollution, ecology is destroyed, overexploitation causes the large tracts of land soil to subside, sulphur dioxide and CO2 emissions are listed as respectively and rank first in the world and second, and the economic loss that causes every year accounts for 3%～7% of national GDP total amount.
China's living resources are very abundant, and main crops kind has paddy, wheat, corn, beans, potato class, oil crops, cotton and sugarcane, and agricultural crop straw is a kind of good clean reproducible energy, and the calorific value of per two tons of stalks just is equivalent to one ton of coal.According to China's geographic distribution and climatic conditions, the southern area waters is many, temperature is high, is fit to crops such as rice cultivation, sugarcane, oil plant, and the northern area four seasons temperature difference is big, is fit to corn, beans and tuber crops growth, so sown area is greater than other areas.Wheat is all generally plantations in China each department, and sown area is maximum with Central China, East China; The cotton place of production mainly is the east and central China area, secondly is North China and west area.During 2000 to 2010, the annual stalk resource of China can the acquisition amount be 3.5 hundred million～3.7 hundred million tons, be equivalent to about 1.7 hundred million tons of mark coals.If these stalk resources are used for generating, be equivalent to 0.9 hundred million kilowatts of fired power generating unit annual operations 5000 hours, annual electricity generating capacity is 4,500 hundred million kilowatt hours.
Stalk is a low-carbon (LC) fuel, and sulfur content only is 0.12%～0.18%, and the sulphur content of coal generally is higher than 0.8%, develops straw power generation under actv. blowdown safety method, can improve environmental quality widely.Coal is as the disposable energy, and with one ton few one ton, and agricultural crop straw is a renewable resource, has inexhaustible resources advantage and cheap cost advantage.
Yet, sound that very beautiful straw power generation does not but slowly come in China's popularization.
Have in the middle of this a lot of technical relevant difficult problems perplexing us, the conveying of fuel-straw is exactly one of difficult point wherein.Band conveyor be most effective in the continuous transport plane, use the most general a kind of type in the power plant.Band conveyor is with the continuous conveying equipment of flexible delivery band as material loaded object and driving component.According to tribology principle, drive load-transfer device by head roll, material is contained on the adhesive tape and adhesive tape moves together and is sent to required place.Band conveyor is compared with the load transfer device of other types, has good performance, can transport continuously under continuous cargo-carring situation, the capacity rating height, it is reliable to operate steadily, and carries continuously evenly, noise is little in the working process, simple in structure, expenditure of energy is little, and operation and maintenance cost is low, easy to maintenance, be easy to realize advantages such as automatic guidance and remote operation, therefore, must be in fuel supplying operation in using widely.But in using, straw power generation carry stalk but to have a lot of problems with belt, the characteristics of stalk are different, bulk density is little and looser, when mass transport speed is higher or when carrying the inclination angle big, stalk suspends easily, can do relative motion each other, so the beginning layering, thereby produce phenomenons such as being detained the arch material.
A lot of for this reason producers adopt the dapple anti-skidding belt in surface or have adopted in belt surface and add cross wall and this problem is solved in the shirt rim.But do like this be not effect undesirable be exactly that cost is too high, too big as the extraordinary belt diversion fee of consumable accessory.
How existing installation being carried out appropriate reconstruction not increasing under the too big cost prerequisite, overcome stalk and have layering in course of conveying, be detained arch material phenomenon, is exactly the difficult problem that the present invention will solve.
Summary of the invention
The purpose of this invention is to provide and a kind ofly can solve the layering that occurs when carrying as stalk fibrid shape bulk material, be detained arch material phenomenon, improve the method that the solution straw power generation fuel of the operational throughput of original equipment and hill climbing ability is carried simultaneously with band conveyor.
For realizing above purpose, technical scheme of the present invention provides a kind of method that straw power generation fuel is carried that solves, and it is characterized in that:
The first step: above band conveyor, install driving chain device capable of circulation additional,
Described driving chain device capable of circulation is made up of driving chain capable of circulation, press member, frame, chain gear actuating device, take-up device, driving chain capable of circulation is installed on the frame by the chain gear actuating device of head end, at least two press member are installed above the driving chain capable of circulation, and take-up device is installed in the tail end of driving chain capable of circulation;
Second step: on band conveyor, load onto stalk, the press member of driving chain capable of circulation is pressed on the stalk, start band conveyor and driving chain device capable of circulation simultaneously, keep band conveyor consistent, the travel line speed synchronization with driving chain device service direction capable of circulation;
The 3rd step: driving chain capable of circulation drives press member, and the gravity by press member carries out the extruding of whole transportation process to fibrous bulk material again, up to being transported to the destination.
Described press member is shaped as strip or bulk, and the bottom is flat or band broach shape.
When belt feeder is carried fibrous bulk material as stalk, if above its material, grant the course of conveying that certain pressure and this pressure put forth effort to be accompanied by whole material, fibrous like this bulk material is because be squeezed in course of conveying, because of having lost the possibility of relative motion each other, and layering can not appear again, be detained arch material phenomenon, can improve delivery speed thus, strengthen hill climbing ability, the present invention is as long as install driving chain device capable of circulation additional above band conveyor, utilize the circulation driving chain to drag the press member that is suspended on the chain, rely on the gravity extrusion fiber shape bulk material of press member to make it be difficult for layering, press member, driving chain capable of circulation provides power by belt drive, drive the cycle operation that the driving chain realization goes round and begins again by mechanical transmission mechanism, and remain the travel line speed synchronization of circulation driving chain and belt.
Advantage of the present invention is to solve layering, the delay arch material phenomenon that occurs when carrying as stalk fibrid shape bulk material with band conveyor, improves the operational throughput and the hill climbing ability of original equipment simultaneously.
