Description
Technical Field
The invention relates to a conveying device, in particular to a device for preventing biomass granular fuel from shaking off.
Background
The biomass granular fuel is a renewable new energy source, and is prepared by crushing, mixing, extruding, drying and other processes of plant wastes such as wood chips, tree branches, corn straws, rice straws and rice husks, and finally is prepared into granular fuel for directly burning the fuel. The biomass granular fuel can indirectly replace energy sources such as coal, oil, electricity, natural gas and the like, has a heat value of 4020 kcal/kg as monitored by a quality supervision and detection mechanism, and has the characteristics of long combustion time, complete combustion, almost no carbon contained in ash slag and the like, so that the heat loss of the incompletely combusted solid is basically zero. And the heat loss of the coal-fired furnace is 7-15%. Through the detection of a related quality inspection mechanism, the total sulfur ST of the biomass granular fuel is 0.02, while the ST of coal which is used in large amount is 0.41, and the emission amount of SO2 after combustion is different by 20.5 times. Therefore, the biomass pellet fuel can replace fuels such as coal, oil and the like, and can reduce atmospheric pollution, so that S02 and C02 harmful gases can achieve basic zero emission. The biomass granular fuel is mainly prepared from wastes such as wood processing, forest pruning and the like and agricultural straws, so that the biomass granular fuel has wide raw material sources, is easy to invest in production, has low cost and high thermal efficiency, and has considerable environmental protection benefits.
According to swedish and european union's classification criteria for biomass particles, if its intermediate classification value is taken as an example, the biomass particles can be described roughly as the following properties: the diameter of the biomass particles is generally 6-10 mm, the length of the biomass particles is 4-5 times of the diameter of the biomass particles, the breakage rate is less than 1.5% -2.0%, the dry basis water content is less than 15%, the ash content is less than 2%, the sulfur content and the chlorine content are both less than 0.07%, and the nitrogen content is less than 0.5%.
After the biomass granular fuel is extruded and formed, when the biomass granular fuel falls into the conveying belt from the forming machine, the biomass granular fuel falls onto the conveying belt after being rebounded for several times because the biomass granular fuel is strip-shaped and has higher hardness; in the conveying process of the conveying belt, the conveying belt vibrates due to transmission, so that the biomass particle fuel on the conveying belt shakes; the biomass particle fuel rebounds or shakes, so that a part of the biomass particle fuel can fall off the conveyor belt, and the workload of workers is increased.
Disclosure of Invention
The invention aims to provide a device for avoiding shaking off of biomass particle fuel, and solves the problems that strip-shaped biomass particle fuel can bounce or shake when moving on a conveyor belt, and a part of biomass particle fuel can fall off from the conveyor belt, so that the workload of workers is increased.
The invention is realized by the following technical scheme:
avoid living beings pellet fuel to shake device that falls, include the conveyer belt through motor drive, all be provided with the billet along its both sides that are on a parallel with the direction of transfer at the conveyer belt upper surface, the axis of billet all is on a parallel with the direction of transfer of conveyer belt, and the distance of keeping away from the side of conveyer belt on the billet to the conveyer belt reduces by edge to conveyer belt conveying center line direction of transfer gradually of conveyer belt, and the length of billet is unanimous with the length of conveyer belt along direction of transfer.
