Problems solved by technology
[0003] However, the above-mentioned dryer has the following defects in use: since the rotation speed of the drum is fixed, the time required for the garbage to move in the drum is also constant, that is, the time for the garbage to be dried is also fixed; , The water content of the primary domestic garbage collected at different times is different, and the temperature of the hot air is also unstable, resulting in inconsistent water content of the dried garbage
When the water content of a part of the garbage meets the requirements, the other part of the garbage cannot meet the requirements of incineration and regeneration due to incomplete dehydration, thus affecting the quality of incineration of garbage and recycled coal
If the moisture content of all garbage meets the requirements, it is necessary to dry the garbage multiple times, which increases the pressure on the treatment equipment and prolongs the cycle of garbage treatment

Embodiment Construction
[0021] For the mechanical structure of an embodiment of the self-regulating garbage dryer of the present invention, see figure 1 : The frame is firmly on the ground, the frame 1 is provided with a supporting wheel 2, and the drum 3 is fastened to the wheel rail as a whole and rested on the supporting wheel 2 to roll, and the motor 5 drives the drum 3 to rotate through the gear reduction mechanism 4. The two ends of the drum 3 are correspondingly provided with an inlet hopper 6 and an outlet hopper 7, and an air inlet 8 and an air outlet 9. The air inlet 8 is connected to the hot air delivery pipe. Pipe is connected, and the rubbish after drying is sent out from the outlet of discharge hopper 7 lower ends. In addition, the present invention preferably also includes an angle adjustment mechanism 10, the angle adjustment mechanism 10 adopts a screw nut mechanism, is arranged at one end of the feeding hopper 6 of the drum 3, and can be directly controlled manually or connected wit...

The invention discloses a self-adjustment garbage drier which is characterized in that a circuit part thereof comprises a control center, a transducer, a D / A conversion module, an A / D conversion module, a moisture content detecting circuit, a temperature detecting circuit and a human-computer interface, wherein the control center internally comprises a temperature signal processing module, a moisture content signal processing module, a fuzzy control module and a proportional-integral control module. The control center can automatically adjust the rotating speed of a motor in a fuzzy control mode according to the high-low of the moisture content of the domestic garbage and the high-low of the hot air temperature and guarantees that the moisture content of the dried garbage is in line with the requirement.
Description
technical field [0001] The invention relates to the field of garbage treatment, in particular to a self-regulating garbage dryer, which is used for drying garbage, so that the moisture content of the garbage after the self-adaptive dryer can meet the requirements of incineration and regeneration. Background technique [0002] In order to achieve the goal of harmless, recyclable and reduction of waste, so that it can be used reasonably, the trend of waste treatment is to incinerate it or make it into recycled coal through technical means. Studies have shown that primary domestic waste contains a large amount of water. The existence of this large amount of water causes the disadvantages of low calorific value, low combustion efficiency, and easy corrosion of equipment during waste incineration and regeneration. Therefore, how to treat waste before incineration and regeneration Its effective drying to remove the moisture contained in it plays a vital role in the whole garbage d...
