Description

Technical Field

[0001] The invention relates to the technical field of garbage disposal, in particular to a domestic garbage incinerator. Background Art

[0002] Domestic waste refers to waste generated in the daily life of residents. It includes various types of waste. During the treatment process, domestic waste is converted into heat energy, smoke and ash through high-temperature incineration. The waste generated by incineration is discharged after being treated by filtering and waste gas treatment technology. There are many types of domestic waste incinerated, and their sizes are different. Small pieces of garbage are easy to ignite and burn quickly, generating high heat, while large pieces of garbage may have cold spots, resulting in uneven heat distribution, affecting the normal operation of the furnace body. Secondly, during the incineration process of domestic waste, condensates will be generated and attached to the filter screen. The condensation of the attached materials causes the ashes after burning to be unable to fall and deposit on the filter screen, making the airflow channel smaller, resulting in gas flow obstruction, and then affecting the combustion efficiency. In view of the above problems, the inventor proposes a domestic waste incinerator to solve the above problems. Summary of the invention

Figure 8As shown, the driving end of the motor 504 drives the right rotating shaft 501 to rotate counterclockwise, and the right rotating shaft 501 drives the left rotating shaft 501 to rotate clockwise synchronously through two rotating gears 503. The two rotating shafts 501 drive the corresponding crushing rollers 502 to rotate synchronously, and the two crushing rollers 502 rotate with each other to crush the domestic waste. The crushed domestic waste falls onto the push plate 608 along the crushing frame 4. The rotation of the left rotating shaft 501 drives the cam shaft 605 to rotate synchronously, as shown in FIG.

The driving shaft 709 drives the driven shaft 706 to rotate periodically and intermittently through the driving wheel 710 and the driven wheel 708. The driving shaft 709 rotates one circle and drives the driven shaft 706 to rotate one eighth of the circle. The driven shaft 706 drives the sliding hopper 704 to rotate in the guide through the rotating rod 707, the movable guide frame 705 and the sliding block 703. Under the guidance of the rod 702, it makes intermittent reciprocating movements, and the crushed domestic garbage is evenly dropped into the combustion chamber 3 through the cooperation of the sliding lower hopper 704 and the push plate 608, and then the crushed domestic garbage is ignited for incineration through the flamethrower 9. The driving shaft 709 rotates and drives the rotating shaft 807 to rotate synchronously.
