Problems solved by technology
Biomass fuels such as crop straws and three forestry wastes are fluffy (crop straws, forestry three wastes) or compacted (such as livestock and poultry manure). If the fuel is not reduced or crushed before entering the boiler, it will cause storage and transportation costs. The improvement is also not conducive to metering and combustion

Embodiment Construction
[0009] like figure 1 As shown, the present invention includes a storage bin 1, the bottom of the storage bin 1 is provided with a conveying mechanism 5, the pretreatment device is also provided with a weight sensor 4 on the conveying mechanism 5, the weight sensor 4 is connected with a signal processor 7, and the signal The processor 7 is connected with the variable frequency speed regulation driving device 6 of the conveying mechanism 5 and the frequency conversion speed regulation device on the compacting and crushing device 3 . In the compacting and crushing device 3, the compacting mechanism is a multi-roller type, and the compacting mechanism is a multi-roller type, which is driven by a frequency conversion speed regulation drive device. Tooth-blade type, through the rotating tooth-blade, the hard lumps of livestock and poultry manure are sheared and pulverized into uniform granules, which are convenient for metering and feeding into the furnace for combustion.

The invention relates to a numerically controlled biomass fuel pretreatment device, which comprises a storage silo, a conveying mechanism and a compaction / crushing device. The conveying mechanism is provided with a weight sensor, the weight sensor is connected with a signal processor, and the signal processor is connected with a variable frequency speed control driving device on the conveying mechanism and a variable frequency speed control device on the compaction / crushing device. Due to the arrangement of the storage silo, the requirements for uninterrupted treatment can be satisfied. The storage, compaction, crushing, measurement and conveying are integrated, the occupied area can be reduced, and the volume of fuels can be reduced to two fifths after the fuels are gradually compacted by pressing rollers arranged in a wedge shape. The clearances among the particles of the compacted fuels are reduced, so cold air can be prevented from entering a hearth to affect the temperature and fuel combustion in a boiler, and also the tempering of hot flame in the boiler can be avoided so as to prevent a feeding device from being burnt. Due to the unit functional mechanisms and the modular digital control, the device can be operated easily and maintained conveniently.
Description
technical field [0001] The invention relates to an energy fuel pretreatment device, in particular to a numerically controlled biomass fuel pretreatment device with the functions of compacting, crushing, storing, metering and transporting fuel. Background technique [0002] Biomass energy is a new type of energy fueled by crop straw, forestry waste and livestock manure. Biomass fuels such as crop straws and three forestry wastes are fluffy (crop straws, forestry three wastes) or compacted (such as livestock and poultry manure). If the fuel is not reduced or crushed before entering the boiler, it will cause storage and transportation costs. It is also not conducive to metering and combustion. Contents of the invention [0003] The object of the present invention is to provide a numerically controlled biomass fuel pretreatment device with the functions of compacting, crushing, storing, metering and delivering the fuel. [0004] The object of the present invention is achieve...
