The maintenance port 1.3 is convenient for the maintenance operation.

[0039] When the garbage incineration device with a drying mechanism incinerates garbage, the specific operation process is as follows:

[0040] Step S1, dry the garbage

[0041] Use the control terminal 11 to start the feeding mechanism to send the garbage into the rotating drum 3 of the drying mechanism in sequence through the guiding feeding port 1.1 and the feeding port. When the weight sensor 10 senses that the weight of the garbage in the rotating drum 3 reaches the upper limit value, the control terminal 11 starts the first power component 5 to drive the rotating rod 9 to drive the baffle 8 close to the limiting plate 7 to close the feeding port and stop feeding. The first power component 5 continuously drives the rotating rod 9 to drive the baffle 8 to closely adhere to the limiting plate 7, and pushes the rotating drum 3 to rotate through the limiting plate 7.

[0042] When the drying mechanism dries the garbage for the first time, during the above feeding and stopping feeding processes, the control terminal 11 starts the first combustion assisting switch to make the first combustor 17 generate a flame to heat the first combustion chamber 1, thereby providing a drying heat source for the garbage in the rotating drum 3. The first power component 5 drives the rotating drum 3 to continuously rotate and the arrangement of the heat conducting holes 3.1 on the rotating drum 3 are convenient for ensuring that the garbage in the rotating drum 3 is quickly and evenly dried. When the garbage incineration device with a drying mechanism just stops the combustion operation, the drying mechanism can utilize the combustion residual heat in the first combustion chamber 1 to dry the garbage with a lower moisture content, so as to save energy and improve the heat utilization rate.

[0043] During the process of drying garbage, the control terminal 11 appropriately adjusts the opening and closing size of the first combustion-aid switch according to the temperature data of the first combustion chamber 1 transmitted by the temperature sensor 12, so as to avoid the garbage from coking due to excessive drying temperature.

[0044] Step S2: Fully burn the dried garbage

[0045] When the weight sensor 10 senses that the weight of the garbage in the rotating drum 3 reaches the lower limit value, it indicates that the garbage in the rotating drum 3 has been fully dried; at this time, the control terminal 11 closes the first power component 5, and the rotating rod 9 drives the baffle 8 away from the limiting plate 7 to open the feeding port; the control terminal 11 starts the second power component 6 to drive the rotating shaft 4 to drive the rotating drum 3 to rotate forward and backward multiple times, so that the dried garbage is poured from the feeding port into the first combustion chamber 1 for combustion; after the dried garbage is poured out, the second power component 6 drives the rotating drum 3 to turn the feeding port of the rotating drum 3 to directly below the guiding feeding port 1.1, facilitating the next feeding and drying;

[0046] When the control terminal 11 starts the second power component 6, the third control switch is appropriately adjusted to start and stop the operation of the blower 13 according to the oxygen concentration data transmitted by the oxygen sensor, so as to ensure that the dried garbage in the first combustion chamber 1 is in an oxygen-deficient combustion state;

[0047] The ash residue after the dried garbage is burned in the first combustion chamber 1 is removed through the slag cleaning port 1.4, and the flue gas after combustion enters the second combustion chamber 2 through the flue gas channel for continuous combustion; the flue gas after combustion in the second combustion chamber 2 is discharged through the chimney 14.

[0048] In step S1 of the present invention, in addition to sensing the weight of the garbage during the drying of the garbage, there are also the following two operation modes:

[0049] (1) For dry garbage with a relatively low humidity, when the temperature sensor 12 detects that the average temperature in the first combustion chamber 1 is lower than 700 °C within half an hour, it indicates that the garbage in the first combustion chamber 1 is about to be burned out; at this time, the control terminal 11 closes the first power component 5, and the rotating rod 9 drives the baffle 8 away from the limiting plate 7 to open the feeding port; the control terminal 11 starts the second power component 6 to drive the rotating shaft 4 to drive the rotating drum 3 to rotate forward and backward multiple times, so that the dried garbage is poured from the feeding port into the first combustion chamber 1 for combustion. After the dried garbage is poured out, the second power component 6 drives the rotating drum 3 to turn the feeding port of the rotating drum 3 to directly below the guiding feeding port 1.1, facilitating the next feeding and drying.

[0050] (2) Customize the dryness of the garbage. Determine the dryness of the garbage by controlling the rotation speed and working time of the first power component 5 set by the control terminal 11. After reaching the set working time, the garbage in the rotating drum 3 is fully dried. At this time, the control terminal 11 shuts down the first power component 5, and the rotating rod 9 drives the baffle plate 8 away from the limiting plate 7 to open the feeding port. The control terminal 11 starts the second power component 6 to drive the rotating shaft 4 to drive the rotating drum 3 to rotate forward and backward multiple times, so that the dried garbage is poured from the feeding port into the primary combustion chamber 1 for combustion. After the dried garbage is completely poured, the second power component 6 drives the rotating drum 3 to turn the feeding port of the rotating drum 3 to directly below the guiding feeding port 1.1, facilitating the next feeding and drying.

[0051] In the garbage incineration device with a drying mechanism of the present invention, the first power component 5 in the drying mechanism drives the rotating rod 9 to drive the baffle plate 8 to approach the limiting plate 7 to close the feeding port, and the first power component 5 continuously drives the rotating rod 9 to drive the baffle plate 8 to closely adhere to the limiting plate 7, and the limiting plate 7 is used to push the rotating drum 3 to rotate. At the same time, with the heat of the primary combustion chamber 1, pre-drying of the garbage is realized, the moisture content is reduced, and the combustion efficiency is improved. After the garbage is dried, the first power component 5 stops working, and the second power component 6 drives the rotating shaft 4 to drive the rotating drum 3 to rotate forward and backward multiple times, so that the dried garbage is poured from the feeding port into the primary combustion chamber 1 for combustion. The above-mentioned garbage drying and pouring combustion can both achieve automated operations, improve work efficiency, and reduce personnel utilization. In addition, the drying mechanism can utilize the combustion waste heat in the primary combustion chamber 1 to dry the garbage with a relatively low moisture content, so as to save energy and improve the heat utilization rate.

[0052] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various modifications and changes. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
