The present disclosure has the following advantages:
(1) the garbage is compressed at high magnification without rebounding. First, the garbage put into the garbage collection system is compressed at high magnification by a hydraulic device to form a cake shape; then, one or more cake-shape garbage are packed. In order to suppress the expansion and rebound of the compressed garbage volume during the packing process or after packing, the garbage bags are hot-melted before the packing process to finalize the shape of the garbage; in order to avoid air bulging in the packing bags after packing, the packing bag is vacuumized in the packing process, which effectively improves the compaction of the garbage. Finally, through the technical solution of hydraulic compression, vacuumize-hot-melt packing, the high-times compressed volume of the garbage does not rebound.
(2) wet garbage alarm. The weight of the garbage before and after compression is weighed by the weighing device and compared, whether there is more wet garbage in the dry garbage is determined by calculating the proportion of the water squeezed out from the garbage, so that an alarm can be sent out when the garbage classification is not standardized, which is beneficial for garbage classification.
(3) The structure is simple and the device is small. The outlet of the vacuum pump is used to lay the garbage packing bags for the packing process to realize the dual use of one pump, which is beneficial to save installation space and reduce manufacturing cost. The garbage forwarding bin has an ingenious structure, using only one motor as power, and the motor drives the chain and the chain connecting rod thereon to run in one direction without reversing, so that the garbage is lifted and pushed into the garbage can, the chain connecting rod and the lifting platform return to the original position, thus the simple structure and control realize multiple functions.
(4) The garbage is in airtight package to prevent gas and liquid leakage, and fully protect the health of operators in the garbage collection, transfer and processing links.

D. weighing the garbage again
the weight of the compressed garbage in the compression and hot-melting bin 3 is weighed again and recorded as G2;
E. determining types of the garbage
the proportion of water that has been squeezed out during the compression process of the recently put garbage is calculated by x=(G1−G2)/(G1−G0), if x is greater than the preset value x0, it is determined that the recently put garbage is mixed with large amount of wet garbage, and the garbage classification is not standardized, and an alarm of non-standard garbage classification is further sent out by the central control display 1;
F. hot-melting the garbage bags
when the count of the garbage bags put in reaches a predetermined number n or the level transducer 309 detects that the put garbage reaches the set level height, the heating device is controlled to start to heat and melt the garbage bags by the central control display 1;
stop heating when the heating device is heated to the predetermined temperature T, the first discharge valve 307 is opened to put the garbage bags (that is compressed garbage and melted garbage bags) into the packing bin 4;
the count of the garbage bags is cleared;
G. packing in vacuum
the vacuum pump 413 is controlled to rotate reversely to inflate the vacuum chamber 412 by the central control display 1;
the packing machine 402 is started to pack the compressed garbage; after the packing is completed, the second discharge valve 414 is opened to put the packing bag 411 containing compressed garbage on the lifting platform 501 located in the forwarding bin 5;
H. relaying the packing bag in the packing bin 4
the vacuum pump 413 is started and controlled to rotate forward by the central control display 1 to vacuumize the vacuum chamber 412, so that the packing bag 411 in the bag box 401 is sucked into the vacuum chamber 412 and is relaid against the inner wall of the vacuum chamber 412;
I. forwarding the garbage
the packing bag 411 containing compressed garbage is lifted by the lifting platform 501, and pushed into the garbage can 7 with the help of the chain connecting rod 502.
In some embodiments, the duration time t for opening the induction rotating cover 202 is 3-10 s.
In some embodiments, the predetermined number n of the count of the garbage bags is 3-20 times.
In some embodiments, the predetermined temperature T of the heating coil 305 (the heating device) is 130-250° C.
In some embodiments, the preset value x0 is 2-10%.
The central control display 1 is started after connecting to the power supply, trigger the first infrared sensor 201 by the hand or an object, after the first infrared sensor 201 receiving the signal, the central control display 1 records the weight of the garbage in the compression and hot-melting bin 3 as G0, at the same time, controls the first motor 203 to open the induction rotating cover 202 and last for 5 s, then put garbage into the garbage putting bin 2.
During the garbage entering the hydraulic bin 301, a signal is sent to the central control display 1 by the second infrared sensor 204 in the garbage putting bin 2 after sensing the passage of the garbage, the central control display 1 counts up by 1, and reads the readings of the electronic scale 306 and records it as G1.
The second motor 304 is started, and the second motor 304 controls the compression plate 302 to reciprocate by controlling the hydraulic cylinder 303. After a compression is completed, the central control display 1 reads the readings of the electronic scale 306 and records it as G2.
The ratio of mass change before and after compression x=(G1−G2)/(G1−G0), if x=7%, which is greater than the preset value x0, such as x0=5%, it is determined that the recently put garbage is mixed with large amount of wet garbage, and the garbage classification is not standardized, an alarm of the non-standard garbage classification is further sent out by the central control display 1. A water storage pipe and a drainage valve are communicate with the bottom of the compression and hot-melting bin 3, after receiving the alarm, the drainage valve is opened to drain out the liquid compressed out from the wet garbage mixed in; under normal circumstances, the garbage classification is standardized, since the system is mainly for dry garbage collection and processing, there is no need to open the drain valve.
Continue to put garbage, and compress the garbage by the hydraulic cylinder 303. When the garbage put in reaches a predetermined number, such as 6 times, or the level transducer 309 detects that the garbage reaches the set level height, the central control display 1 activates the electrically heated coils 305 to start heating. When the temperature of the electrically heated coil 305 reaches a predetermined temperature, such as 160° C., the garbage bag in the hydraulic bin 301 undergoes hot-melting and shrinkage, and the garbage in the garbage bag is maintained in a compressed state without rebounding.
the central control display 1 controls the third motor 308 to open the first discharge valve 307, so that the garbage enters the packing bin 4 from the compression and hot-melting bin 3, and the count of the garbage bags put in is cleared.
In the packing bin 4, the packing bag 411 is extended from the bag box 401, and laid in the vacuum chamber 412, so that the garbage bags (that is compressed garbage and melted garbage bags) from the compression and hot-melting bin 3 are directly wrapped by the packing bag 411.
the vacuum pump 413 is controlled to rotate reversely to inflate the vacuum chamber 412, at this time, the gap between the packing bag 411 with garbage and the vacuum chamber 412 is enlarged, and the air in the packing bag 411 is squeezed out, so that the packing bag 411 more densely wraps the garbage inside. If the vacuum pump 413 provides too much gas and the pressure is too high, the decompression valve 417 is opened to prevent the packing bag 411 extending from the bag box 401 from being displaced or broken.
Start the packing machine 402 to pack the compressed garbage, the fourth motor 408 and the sixth motor 410 are controlled by the central control display 1 to respectively drive the first pushing rod 403 and the second pushing rod 407 to move horizontally perpendicular to each other at different heights, so as to tighten the packing bag 411, and finally the packing bag 411 is closed at a fixed corner, during this process, the vacuum pump 413 continually to inflate to ensure the excess air in the packing bag 411 is squeezed out.
The vacuum pump 413 stops working.
Subsequently, the first heating wire 404 and the second heating wire 406 simultaneously heats and melts the fixed corner, then the fifth motor 409 is started to drive the cutter 405 between the first heating wire 404 and the second heating wire 406 to cut the closed position, the garbage packing is completed.
The central control display 1 controls the seventh motor 416 to start operation, the second discharge valve 414 is opened and the packing bag 411 containing compressed garbage falls on the lifting platform 501 located in the forwarding bin 5.
The central control display 1 controls the vacuum pump 413 to rotate forward, the vacuum chamber 412 is vacuumized, so that the packing bag in the bag box 401 is sucked into the vacuum chamber 412 and clings to the inner wall of the vacuum chamber 412, thereby completing laying the packing bag for the next garbage packing.
At the same time, the eighth motor 506 is started, the chain 504 is driven by the gear 503 to rotate a full turn, the chain connecting rod 502 moves synchronously with the chain 504. When the chain connecting rod 502 moves from bottom to top, it drives the sliding groove 507 to drive the lifting platform 501 to move upward; when the chain connecting rod 502 located upward moves from left to right, the lifting platform 501 does not move, the chain connecting rod 502 only moves in the sliding groove 507 from left to right, which pushes the packing bag 411 located on the lifting platform 501 to move from left to right and fall into the garbage can 7; when the chain connecting rod 502 moves from top to bottom, it drives the sliding groove 507 to drive the lifting platform 501 to move downward; when the chain connecting rod 502 located downward moves from right to left, the lifting platform 501 does not move, the chain connecting rod 502 only moves horizontally in the sliding groove 507 of the lifting platform 501, at this point, the chain 504 has completed one turn, the chain connecting rod 502 and the lifting platform 501 both return to the original position and complete the transfer of the garbage on the lifting platform 501 to the garbage can 7.
