High-quality biomass fuel processing system

Abstract

The invention discloses a high-quality biomass fuel processing system which comprises a chipping machine. The feeding end of the chipping machine is connected with the output end of a feeding belt conveyor which is provided with an iron removal alarm. The discharging end of the chipping machine is connected with the input end of a discharging belt conveyor. The output end of the discharging belt conveyor is connected with a vibration screen. A first impurity removal belt conveyor is arranged below the vibration screen. The high-quality biomass fuel processing system is an impurity removal, crushing and processing system specifically designed for biomass, iron blocks, mud and other impurities mixed in the biomass can be effectively removed, and therefore the quality of biomass fuel is substantially improved. The iron removal alarm gives out an alarm and sends out a signal to a control system when detecting iron components, and an operator quickly and accurately finds out and takes out the iron impurities according to the alarm position. Thus, the processing efficiency of the biomass fuel is improved, and the equipment safety in the processing system and the personal safety of operation staff of the processing system are also effectively guaranteed.

Description

technical field [0001] The invention relates to biomass fuel processing equipment, in particular to a high-quality biomass fuel processing system. Background technique [0002] Biomass such as straw, twigs, bark, roots, and leftovers from wood processing plants can be used as biomass fuel for biomass power generation after proper processing. The biomass has different shapes and sizes, and most of them contain impurities. Some of them are mixed with iron impurities such as processing tools and iron nuggets during their production process, and some are entrained with soil clods or mud chips. Therefore, before these biomasses are utilized as biomass fuels, they need to be crushed and processed, and impurities such as soil and iron lumps mixed therein that affect the quality of biomass need to be removed. [0003] At present, there is no special system equipment for processing biomass, and the chipper system of the paper industry is basically borrowed. This chipper system has t...

Problems solved by technology

[0003] At present, there is no special system equipment for processing biomass, and the chipper system of the paper industry is basically borrowed. This chipper system has the following disadvantages: 1) In the process of using this system to crush biomass, once Biomass is mixed with iron and other impurities, and the iron hits the blade of the chipper, which may easily cause damage to the blade; 2) The impurities in the biomass are likely to cause damage to the body of the chipper, and even affect the For the personal safety of chipper operators, in actual production, during the process of processing bark by chippers, flying knives of chippers sometimes occur, which in turn damages the shell of the chipper and causes injuries to the parts of the chipper The incident of the operator; 3) The biomass fuel processed by the chipper system has a large soil content, and the quality needs to be improved
