Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a garbage incinerator, and more particularly to a fully automatic small-sized garbage incinerator.

[Conventional technology]

Inputting waste into conventional small waste incinerators was often done manually, and most small incinerators were batch-type, and there were no incinerators that automated the entire process from feeding to incineration.

[Purpose of the invention]

The purpose of the present invention is to completely automate the process from input to incineration, which did not exist before, so that once the garbage is placed in the storage room, it is disposed of without any odor, sight, or touch. The objective is to obtain an incinerator that produces only sterilized ash.

[Structure of the invention]

The present invention provides screw blades on the inner circumferential surface of a cylindrical rotating outer cylinder that is arranged at a steep angle or vertically and whose lower side is located in a storage chamber, and is equipped with a screw whose axis is centered within the rotating outer cylinder. It consists of a garbage conveyance path in which a rotating outer cylinder containing screw blades and a screw shaft are connected to rotation sources in opposite directions, and an incineration chamber provided with an input port communicating with an upper duct of the rotating outer cylinder. It is a fully automatic small garbage incinerator with sensors such as laser beams installed in the incinerator chamber to determine the upper and lower limits of the inside of the furnace, and the sensors and the garbage transport path are connected.

[Function] Starting The storage room has a sensor with a photoelectric switch for upper and lower limits, and the garbage pool energizes the power supply of the screw conveyor that reaches the upper limit sensor, and the screw conveyor picks up the garbage and incinerates it. Automatically feed into the furnace.

When the screw conveyor starts and garbage begins to enter the furnace (after 2 to 5 minutes), the furnace's oil burner and blower are energized to ignite the garbage.

The screw conveyor continues to operate.

Continuation of incineration Incineration in the furnace and feeding of waste into the furnace using the screw conveyor will continue as is.

Inside the furnace, there are two laser beam sensors installed at the upper and lower limits.

When the laser beam sensor reaches the upper limit, the conveyor is stopped, and garbage is no longer fed into the furnace, allowing only incineration to proceed.

When the position of the garbage falls to the lower limit of the laser sensor, the screw conveyor moves again, continues feeding until it reaches the upper limit sensor, and stops at the upper limit sensor.

Incineration continues in the incinerator by repeating this process.

Stop When the garbage in the storage chamber is empty, the conveyor is stopped by a signal from the lower limit sensor in the storage chamber.

Furnace temperature control, oil burner, and blower The oil burner plays the role of supplying heat during ignition and combustion, and is self-combusting when not needed. Inside the furnace, set the magnetic valve in advance (700
Control is automatically performed using a temperature sensor (from 200°C to 800°C), and when the incineration material is burned out and the temperature inside the furnace drops (preset to 200°C to 300°C), the temperature sensor will stop the furnace.

Ash removal The ash removal device swings at a preset time and drops the ash into the ash tray at the bottom.

〔Example〕

In the figure, 1 is connected to the cylindrical rotary outer cylinder 20 of the screw conveyor 3 which is steeply inclined in the storage room, and the duct 4 at the upper end thereof leads to the incineration chamber 5 of the furnace body.

The rotary outer cylinder 20 has screw blades 22 on its circumferential surface, and a screw 23 with the center thereof as the shaft 21 is installed inside the rotary outer cylinder 20, and both screws are offset from each other and bite into the other, and the rotary outer cylinder 20 has a chain mechanism. 24 to the electric motor 27, and the screw shaft 21
is connected to an electric motor 26 via a chain mechanism 25 to rotate in the opposite direction.

2 is a photoelectric switch, and 6 in FIGS. 2 and 3 is an oil burner, which is ignited intermittently by a temperature sensor 11 to promote heating. 7 is a blower, 8 and 9 are upper and lower sensors using laser beams, and when the garbage reaches the upper limit sensor 8, the screw conveyor 3 stops, and the input of garbage into the furnace body incineration chamber 5 is stopped.
Only incineration progresses and when the lower limit sensor 9 is reached,
The screw conveyor moves again and begins to load garbage. Incineration is automatically continued by repeating this process. Reference numeral 12 denotes a rostol, and numeral 13 denotes an ash receiver. To remove the ash, the rostol 12 is swung at a preset time to drop the ashes into the ash receiver. 14 is a dry cyclone,
15 is a chimney, and 16 is a Roestre rocking motor.

〔Effect of the invention〕

As described above, the present invention connects the conveyance path that feeds garbage into the incineration chamber at a steep angle with the sensor inside the incineration chamber, so that when the amount of unburned garbage increases in the incineration chamber, the amount of garbage sent from the conveyance path is reduced. As combustion progresses, a considerable amount of waste can be sent to the combustion chamber again. Therefore, the combustion of waste can be continued extremely efficiently.
