Description

Technical Field

[0001] The invention relates to the field of garbage incineration technology, and in particular to a garbage incineration boiler and a construction method thereof. Background Art

[0002] As the size of cities in my country continues to grow, the amount of garbage produced in cities is also increasing, and the accumulated garbage has become a burden on urban development. In order to effectively treat urban garbage and reduce the amount of urban garbage piled up, many cities use incineration to effectively treat urban garbage.

[0003] Waste incineration is usually carried out in waste incineration power plants. Through appropriate thermal decomposition, combustion, melting and other reactions, the waste is oxidized at high temperatures to reduce its volume and become residues or molten solid substances. However, during the process of waste incineration, waste is prone to accumulation in the waste incineration equipment, which makes it extremely difficult to incinerate the waste.

[0004] With respect to the above-mentioned related technologies, the inventors believe that garbage is easily accumulated in the garbage incineration equipment, which makes it difficult for the garbage at the bottom to be completely burned, resulting in incomplete combustion of the garbage and low garbage incineration efficiency.

[0008] By adopting the above technical solution, when in use, the garbage is put into the incinerator, and the garbage falls to the top of the lifting grid. The combustion device is adjusted so that the combustion device burns part of the garbage. Then, the stepper motor is adjusted, and the driving shaft of the stepper motor drives the lifting screw to rotate. Under the action of the guide rod, the lifting grid reciprocates along the height direction of the incinerator. During the lifting and lowering process of the lifting grid, the burned garbage falls from the gap of the lifting grid, and the unburned garbage on the lifting grid is lifted. Under the action of the combustion device, the combustion device can directly and fully burn the unburned garbage, thereby improving the incineration efficiency of the garbage. Through the lifting grid, under the driving action of the stepper motor, the lifting grid can lift the unburned garbage, so that the combustion device can directly and fully burn the unburned garbage, thereby improving the efficiency of garbage incineration.

[0016] By adopting the above technical solution, when garbage falls into the pushing trough, the pushing mechanism is adjusted, and the pushing mechanism can push the garbage from the pushing trough into the incinerator, so that the garbage is burned in the incinerator. The set pushing device can push the garbage falling into the pushing trough into the incinerator under the action of the pushing mechanism, which can improve the incineration efficiency of the garbage.

It also includes a blocking mechanism 64 that can block the feed port of the incinerator 1, and the blocking mechanism 64 includes a blocking door 641, a rotating shaft 642 and a rotating cylinder 643. The rotating shaft 642 passes through both ends of the blocking door 641 and is connected to the incinerator 1 through a bearing. The base of the rotating cylinder 643 is fixed to the incinerator 1 by bolts, and one end of the rotating shaft 642 extending out of the incinerator 1 is connected to the driving shaft of the rotating cylinder 643 through a coupling. By adjusting the rotating cylinder 643, the driving shaft of the rotating cylinder 643 can drive the rotating shaft 642 to rotate, so that the blocking door 641 can block the feed port of the incinerator 1.

[0049] The implementation principle of a garbage incineration boiler according to an embodiment of the present invention is as follows: when in use, the garbage is put into the push trough 62, the push cylinder 632 is adjusted, and the driving shaft of the push cylinder 632 drives the push plate 631 to move, and the push plate 631 pushes the garbage in the push trough 62. When the garbage is about to enter the incinerator 1, the rotating cylinder 643 is adjusted, and the driving shaft of the rotating cylinder 643 drives the rotating shaft 642 to rotate, and the rotating shaft 642 drives the blocking door 641 to move, so that the feed port of the incinerator 1 is in an open state, so that the push plate 631 can push the garbage into the incinerator 1. When the garbage enters the incinerator 1, the garbage falls on the top of the lifting grid 3. Under the action of the combustion device 2, the combustion fan 21 can incinerate the garbage.

[0050] When it is necessary to burn the garbage at the bottom of the incinerator 1, the stepper motor 41 is adjusted, and the driving shaft of the stepper motor 41 drives the lifting screw 42 to rotate, and under the action of the guide rod 43, the lifting grid 3 reciprocates along the height direction of the incinerator 1. During the lifting and lowering process of the lifting grid 3, the burned garbage falls from the gap of the lifting grid 3, and the unburned garbage on the lifting grid 3 is lifted, so that the combustion fan 21 continues to burn the unburned garbage.

[0051] At the same time, the blower 52 is adjusted, and under the action of the oxygen supply mechanism 51, the blower 52 blows the oxygen blown out by the oxygen supply mechanism 51. The oxygen passes through the main air duct 531, then disperses into the air guide duct 532, and finally is injected into the incinerator 1, providing sufficient combustion conditions for the combustion in the incinerator 1. Under the action of the guide plate 11, all the garbage that falls to the bottom of the incinerator 1 can be blown up, and the garbage at the bottom of the incinerator 1 can continue to be burned by the combustion fan 21, which can improve the combustion efficiency of the garbage entering the incinerator 1.

Then, adjusting the combustion fan 21, the combustion fan 21 blows the ignited fuel into the incinerator 1, so that the fuel can directly incinerate the garbage. Then, adjusting the stepper motor 41, the driving shaft of the stepper motor 41 drives the lifting screw 42 to rotate. Under the action of the guide rod 43, the stepper motor 41 can drive the lifting grid 3 to reciprocate along the height direction of the incinerator 1. During the combustion process, the fully burned garbage becomes slag and falls from the gap of the lifting grid 3, which can expose the incompletely burned garbage and be fully burned by the fuel, thereby improving the combustion efficiency of the incinerator 1.
