Claim 5:
6. A dry garbage collection method with compressing and packing functions, wherein the method is applied to the dry garbage collection system with compressing and packing functions of claim 1, the method comprises the following steps:
A. disposal of garbage:
when the first infrared sensor is triggered, recording a weight of the garbage in the compression and hot-melting bin as G0 at this time; opening the induction rotating cover, and then closing it after a duration time t;
B. weighing of the garbage:
when the second infrared sensor is triggered, increasing a count of the garbage bags put in by one;
recording the weight of the garbage in the compression and hot-melting bin as G1 at this time;
C. compression of the garbage:
controlling the hydraulic device by the central control display to compress the garbage;
D. weighing of the compressed garbage:
weighing a weight of compressed garbage in the compression and hot-melting bin again and recording as G2;
E. determination of the type of garbage:
calculating a proportion of water squeezed out during a compression process of recently put garbage by x=(G1−G2)/(G1−G0), if x is greater than a preset value x0, determining that the recently put garbage is mixed with a large amount of wet garbage, and a garbage classification is not standardized, and sending out an alarm of a non-standard garbage classification by the central control display;
F. hot-melting of garbage bags:
when the count of the garbage bags put in reaches a predetermined number n or the level transducer detects that the put garbage reaches a set level height, controlling the heating device by the central control display to perform hot-melting on the garbage bags;
stopping heating when the heating device is heated to a predetermined temperature T, opening the first discharge valve to put the garbage bags into the packing bin; clearing the count of the garbage bags;
G. packing in vacuum:
controlling the vacuum pump to rotate reversely to inflate the vacuum chamber by the central control display;
starting the packing machine to pack a compressed garbage; after a packing is completed, opening the second discharge valve to put a packing bag containing the compressed garbage on the lifting platform located in the forwarding bin;
H. laying of a new packing bag in the packing bin:
controlling the vacuum pump to start and rotate forward by the central control display to vacuumize the vacuum chamber, so that a new packing bag in the bag box is sucked into the vacuum chamber and is laid on an inner wall of the vacuum chamber;
I. transmission of the garbage:
lifting the packing bag containing the compressed garbage by the lifting platform, and pushing it into the garbage can with a help of the chain connecting rod.
