Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an automatic loading device for large waste incinerators.

[Prior Art] Conventionally, there are two ways to load garbage into large incinerators: one is to use a garbage crane, the other is to push the garbage in using a large piston. However, in both cases, the loading or pushing is done mechanically and manually on the spot. Therefore, it was not possible to automatically achieve that goal. Conventionally, large garbage incinerators are loaded by transporting and storing garbage from outside into the storage chamber using a transport vehicle, passing a rail connecting the storage chamber and the upper part of the furnace, and equipping the garbage with a hoist. In many cases, waste was placed into the incinerator according to the incineration conditions in the furnace, or waste transported into the incinerator by a waste transport vehicle was inserted using a special device, but all of these procedures were manual operations.

[Problems to be Solved by the Invention] The problems of the present invention are to completely automate the conventional manual operation and eliminate the need for the input port to be located higher than the GL as in conventional storage chambers. Our objective is to provide an automatic incinerator that allows garbage trucks, garbage trucks, and other vehicles to directly store waste from GL.

[Means for Solving the Problems] The means of the present invention includes a storage chamber in which garbage from the outside world can be easily transported and stored, a belt conveyor is provided at the bottom of the storage chamber, and the storage chamber is equipped with a belt conveyor at the bottom of the storage chamber. First, a cylindrical screw conveyor installed at a steep angle was installed after passing through a crusher. The cylinder is connected to a prime mover that rotates the outer cylinder and screw shaft in opposite directions.The cylinder that communicates with the screw conveyor has a mechanism that detects when a predetermined amount of dust is inside and stops the conveyance path. In addition to being equipped with optical fiber or photoelectric switch-based sensors, the cylinder is equipped with a piston that throws waste into the incinerator below.

[Example] Reference numeral 1 denotes a storage chamber, a belt conveyor 2 is equipped at the bottom, and a vibrator 3 is installed on the peripheral wall of the storage chamber 1. 10 is a crusher that receives garbage that has fallen onto the belt conveyor 2.

There is a screen 4 at the top of the storage room, and large garbage is caught by this screen.

A foldable lid 5 is provided on the top of the screen 4,
Prevents odors from escaping to the outside.

An electric motor 6 is attached to move the belt conveyor 2 to the storage room. The waste destined for the crusher 10 enters a pushing device 7 located at the top of the crusher, and is evenly pushed into a crusher chamber 9 and crushed by a stirring arm 8 of the pushing device. Reference numeral 12 denotes an electric motor for horizontally moving the stirring arm 8, which crushes the screws to such an extent that they do not catch or wrap around the screw conveyor.

13 is a vertical screw conveyor, which includes a screw 18 attached to the inner peripheral surface of an outer cylinder 13a rotated by a motor 20, and a screw shaft 13b in the center.
It consists of a screw 19 provided in the outer cylinder 13.
a is rotated by the motor 20, and the screw shaft 13
b is rotated by the motor 21 in the opposite direction to the outer cylinder 13a, and transports the waste sent through the destroyer to the upper level. 22 and 23 are bearings for the screw shaft 13b.

The upper part of the screw conveyor 13 is the duct 14
It communicates with the vertical cylinder 15 through the motor 17.
A piston 16 that operates by converting the rotation of
When the dust accumulated in the cylinder 15 reaches a predetermined amount, a sensor 24 using an optical fiber or a photoelectric switch stops the transport of the dust.

When a signal is transmitted from inside the furnace, the piston 16 inside the cylinder descends and throws the waste into the furnace.
When the injection is completed, the piston 16 rises again and returns to its original position. Then, a limit switch works, energizing the power to transport the waste from the storage chamber to the cylinder, starting them all at once.

In the figure, reference numeral 25 indicates an outlet for introducing the odor into the furnace as combustion air without dissipating it. Reference numeral 24 is a garbage amount detection sensor for detecting the amount of garbage in the storage room, which uses a special level switch. The level switch uses a phototube sensor to detect when there is no garbage in the storage chamber and turns off the electricity to the conveyance path.

[Operation] Garbage transported to the storage room is sent to a vertical screw conveyor via a crusher by a belt conveyor, and is pushed upward through a duct to accumulate in a vertical cylinder and is transported into an incinerator by a piston. let it fall.

[Effects of the Invention] According to the present invention, all garbage incineration including the most important input operation is automated, and the performance of a large-scale garbage incinerator is significantly improved. In particular, it is equipped with a vertical screw conveyor to raise waste from a low position to a high place and drop it into an incinerator from there, allowing for smooth incineration in a relatively narrow space.
