[0002] With the continuous development of social production and life, the amount of household garbage is increasing, which has become an urgent environmental problem. Internationally, the traditional landfill method has been gradually eliminated, and a more efficient and higher energy recovery rate combustion method has been used instead. Combustion method converts combustible garbage into heat energy, realizes the reduction, resource utilization and harmless treatment of garbage, however, this method faces severe challenges in practical application: how to ensure that combustible garbage can be fully combusted, while ensuring that emissions do not pollute the atmospheric environment, which is the key problem of current combustion method for treating household garbage, in other words, the device for incinerating garbage must have efficient and stable crushing and combustion capacity to ensure that garbage can be fully combusted, thereby making the pollutant emission meet the environmental protection standard requirements.

[0003] However, the traditional garbage incinerator feeding system is designed to face large hard objects, soft fibers and high water content substances mixed together in the garbage, and a single crushing mechanism cannot achieve comprehensive and effective crushing.

[0037] Working principle: the feeding and crushing device for the mechanical fluidized bed garbage incinerator realizes efficient crushing and draining treatment of garbage through a series of precisely designed mechanical structure linkage, and provides high-quality feeding for the incinerator.

[0038] Firstly, when the motor 3 is started, the first belt pulley 4 driven by the rotating shaft of the motor 3 starts to rotate, the first belt pulley 4 is tightly connected with the second belt pulley 7 and the third belt pulley 9 through a belt, forming a stable transmission system, and the transmission system drives the blade crushing shaft 6 and the crushing rotating shaft 8 to rotate synchronously and stably.

[0039] In the garbage crushing cylinder 2, the first crushing device plays a key role, the transmission gear one 13 fixedly connected with the crushing rotating shaft 8 is engaged with the transmission gear two 14 on the other crushing roller 12, so that the two crushing rollers 12 form a relative rotation in the garbage crushing cylinder 2. A plurality of crushing blades 15 are uniformly distributed on the side surfaces of the two crushing rollers 12, and the crushing blades 15 are staggered and distributed, and cooperate with the crushing reinforcing pieces 11 on the inner wall of the garbage crushing cylinder 2.

[0040] The preliminarily crushed garbage falls into the draining conveying device, the bottom side inner wall of the material hopper 17 is designed as two inclined surfaces inclined to the middle, facilitating the natural sliding and concentration of the garbage.

[0041] In the draining conveying device, the auger 19 plays a key role, one end of the blade crushing rotating shaft 6 is connected with the rotating shaft of the auger 19 through the fourth belt pulley 16 and the transmission belt, driving the auger 19 to rotate in the conveying cylinder 21.

[0042] In addition, the device also ingeniously utilizes the continuity of mechanical transmission. When the blade crushing rotating shaft 6 rotates, not only the crushing blades 15 are driven to perform crushing work, but also the rotation of the auger 19 is driven through the fourth belt pulley 16 and the transmission belt, realizing the synchronous performance of crushing and draining conveying. This design not only improves the work efficiency, but also reduces the energy consumption.

[0043] In summary, the garbage incinerator feeding and crushing device based on the mechanical fluidized bed realizes efficient crushing and draining treatment of the garbage through the motor 3 linkage belt pulley and transmission gear driving the key components such as the crushing roller 12 and the auger 19 to work cooperatively.
