Problems solved by technology

[0003] The purpose of the present invention is to overcome the above-mentioned existing problem that wood chips are directly added to the boiler when replacing other fuels in the combustion of the boiler, which makes it inconvenient to add during combustion, and the powder is easy to spill everywhere, inconvenient to clean up, and the utilization rate of heat energy is low during combustion. Problem, a system based on particle regeneration of wood chips is designed. This system improves the utilization rate of wood chips by processing wood chips into a granular structure. It has high molding efficiency, high heat energy utilization rate during combustion, and convenient addition. There are other residues, which solves the problem that when replacing other fuels in the boiler combustion, wood chips are directly added to the boiler, which makes it inconvenient to add during combustion, and the powder is easy to spill everywhere, which is inconvenient to clean up, and the heat energy utilization rate is low during combustion. The problem

The packaging system is mainly composed of a finished product warehouse 23 and a collection bag 25. The bottom of the bottom is connected, and...

Embodiment 2

[0019] Such as figure 2 , image 3 As shown, the granulator 18 is mainly composed of an installation cylinder 1, a shaper and a power mechanism. Between the feeding mechanism and the installation cylinder 1, the feeding mechanism includes a feeding cylinder 7, which is connected with the former to form an integral structure. The center line of the center line is arranged symmetrically, and each group of transmission mechanisms is mainly composed of cam one 6, cam two 14, and scraper 12. The cam one 6 is provided with a pin shaft 13, and the pin shaft 13 passes through the cam one 6 and cam two 14 at the same time. The cam one 6 is connected with a sleeve 8, the sleeve 8 is connected with the cam one 6 as an integral structure, the sleeve 8 is provided with an installation shaft 10, and the installation shaft 10 is fixed with the installation cylinder 1, and the cam two 14 is provided with an adjustment column 11 , the adjusting column 11 passes through the cam 2 14, the out...

Embodiment 3

[0021]Utilize the negative pressure adsorption machine 15 to absorb the wood chips into the rotary cutter 16 through the pipeline, chop them into powders with a particle size of 4-20 mesh, mix and stir various wood chips through the mixer 17, and then input them into the granulation system and After the temperature is raised to 120° to 130°, the granulation starts, and the shaped granules are input into the cooling system through the through hole on the granulator to cool down to normal temperature, and then packed and collected after being vibrated and screened. Adsorb and polymerize all kinds of debris produced in the production of furniture in the factory, such as shavings and sawdust, and then transport them to the granulator after stirring. Due to the special structure of wood materials, it is easy to produce burnt paste at high temperatures , it remains hard at low temperature, and it needs to be softened during granulation, so that the powder can maintain a softened stat...

Description

technical field [0001] The invention belongs to the furniture industry, and in particular relates to a system based on particle regeneration of wood chips. Background technique [0002] Sawdust refers to the sawdust and shaving powder left over from wood processing. It is mainly used as fuel and light bone filler, or compounded into wood-based panels, such as MDF. It can also be used as a raw material for papermaking. It can be used as civil heating and living energy, has a high combustion utilization rate, is easy to store, easy to use, and is safe and hygienic. It is generally welcomed for home use. It can also be used in biomass industrial boilers, as an industry, to replace coal, heavy oil and natural gas to solve environmental pollution. It can also be used as fuel for thermal power generation. Every 10,000 tons of wood chips burned can replace 8,000 tons of standard coal, reducing SO 2 Emission of 160 tons, smoke emission of 80 tons, CO 2 Discharge of 14,400 ton...
