Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of use] The present invention relates to an automatic feeder for feeding a large amount of refuse to an incinerator.

[Prior Art] Conventionally, in order to put waste into an incinerator, what was collected manually in one container was opened by opening the door of the incinerator. Therefore, it was inefficient.

When a large amount of waste is thrown into the incinerator by a hoist, it falls on the incinerator being incinerated in the furnace, so the flame disappears temporarily and the temperature drops, preventing smooth incineration, resulting in incomplete combustion. It is not only inefficient, but also a frequent cause of soot and dust.

[Problems to be Solved by the Invention] An object of the present invention is to eliminate the conventional drawbacks by automatically and flowingly throwing in dust and feeding it according to the incineration force of the furnace.

[Means for Solving the Problems] Means of the present invention are as follows.

Two upper and lower chambers are formed in series between the waste transporting device and the incinerator, the two chambers are connected to each other, an intermediate door that shuts off is provided so that it can be opened and closed, and an extrusion lid that presses the dust is installed in the upper chamber so that it can move up and down. , A stirring screw is installed vertically on the middle shaft of the lower chamber, an intermediate door with multiple inner screw blades is opened and closed between the lower chamber and the incinerator charging port, and a beam sensor for raising and lowering the extrusion lid is installed in the lower chamber. Installed in the vicinity of the incinerator inlet, a leather sensor that rotates the rotary outlet with screw blades on the inner surface and the stirring screw of the center shaft in opposite directions is installed in the furnace and the amount of dust in the upper chamber is the upper limit. Automatic duster with a beam sensor in the upper chamber that stops the dust carrier when it reaches

[Embodiment] In FIG. 1, reference numeral 1 is a waste carrier, 2 is an incinerator, and a top and bottom 2 partitioned by an intermediate door 9 between a connecting tube 23 at the tip of the waste carrier 1 and an input port 3 of the incinerator 2. Two cylindrical rooms 6 and 7 are provided. The upper chamber 6 temporarily stores the dust from the dust carrier 1 and sends it to the lower chamber 7. An intermediate door 9 between the upper and lower chambers 6 and 7 is provided so as to be openable and closable in the horizontal direction, and as shown in FIG.
The push-out lid (10) is attached to the upper part of the above so that it can move up and down. 8
Indicates a beam sensor in the lower chamber 7, and by this signal, the intermediate door 9 is opened and the pushing lid 10 is lowered. The push-out lid 10 is raised after the intermediate door 9 is fully closed.

As shown in FIG. 3, the push-out lid 10 has the lid fixing end 11 with the upper chamber 6
To the left and right, is fixed to the chain 24, and can be moved up and down from the push-out lid driving shaft 12 via the transmission mechanism 25.

The intermediate door 9 is opened and closed by the transmission mechanism 26 from the opening / closing shaft 22. Reference numeral 21 denotes a drive motor for the shafts 12 and 22.

Reference numeral 14 is a center shaft located at the bottom of the lower chamber 7, and a blade-shaped stirring screw 15 is provided in the lower chamber 7
It is equipped with a rotary discharge port 13 in which a plurality of screw blades 13a are protruded inward under 15 and a center shaft 14 has a transmission mechanism 27 at the upper end as a motor.
In succession to 20, the transmission mechanism 28 of the rotary discharge port 13 is connected to the motor 19 so that the screw 15 and the rotary discharge port 13 provided with the screw blade 13a on the inner surface are rotated in opposite directions.

The rotary discharge port 13 is connected to the incinerator charging port 3 in which the lower door 18 is opened and closed.

Reference numeral 4 in the figure denotes a laser sensor attached to the inside of the incinerator 2, and the motors 20 and 19 are operated by the signal thereof to rotate the center shaft 14 by the motor 20 and the motor 19 reversely rotates the rotary discharge port 13.
Reference numeral 17 denotes an upper limit beam sensor, which is attached inside the upper chamber 6, and when dust is accumulated up to this height, the signal indicates that the dust transport device 1
Is stopped and the transmission of the beam sensor 8 below the lower chamber 7 is awaited. Reference numeral 5 indicates an exhaust fan, and 31 indicates an automatic feeding machine main body.

[Operation of the Invention] When the dust from the dust carrier 1 is temporarily stored in the upper chamber 6 and the lower chamber 7 is emptied, the beam sensor 8 in the lower chamber operates, the intermediate door 9 is opened, and the upper chamber 6 is opened after the full opening. Extruder lid 10
Lowers to surely drop dust in the upper chamber into the lower chamber 7. Since the push-out lid 10 is raised after the intermediate door 9 is fully closed, the incinerator 2 is not opened to the atmosphere and the imbalance of the combustion state due to the inflow of outside air is prevented.

The dust that has moved into the lower chamber 7 is rotated by the signal from the laser sensor 4 so that the stirring screw 15 and the rotary discharge port 13 rotate in opposite directions, and is sequentially sent into the incinerator 2.

In the upper chamber 6, the dust is dropped into the lower chamber 7 and when the pushing lid 10 reaches the rising end, the dust conveying device 1 is activated by the signal and the dust is sent to the upper chamber 6. When the amount of dust in the upper chamber 6 reaches the height of the upper limit beam sensor 17, the laser sensor 4 works as described above to stop the dust carrier 1 by the signal, and the signal of the beam sensor 8 in the lower chamber is changed. wait.

The lower door 18 is always open during the incineration work, but is closed at the same time when the work is completed and the blower 5 is stopped. Even if the blower 5 is stopped, there is residual heat and some embers in the incinerator 2, but these are prevented from being discharged from the incinerator input port 3, and the incinerator input port 3 and the garbage automatic input device 16 The lower door 18 is closed for complete safety and further safety.

[Advantages of the Invention] According to the present invention, the functions of the respective sensors prevent the dust from being thrown into the incinerator during combustion all at once, and the dust is sequentially fed into the furnace according to the combustion state. Because it is done
Combustion can be smoothly continued except for burning flames of dust during burning or reducing the temperature in the furnace to cause incomplete combustion.
