Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a garbage disposal apparatus using a rotary drum type garbage storage and discharger and any type of garbage incinerator.

In the case of such a processing device, at present, the input time and input amount depend on the operator's ability.

For this reason, it is difficult to feed the incinerator in a way that is appropriate for its combustion conditions, resulting in incomplete combustion due to too much input, and uneven garbage in the incinerator due to inappropriate input amount or charging time. , there were problems such as lowering combustion efficiency.

In view of the above-mentioned problems with conventional processing equipment, this invention automatically operates the garbage storage and discharge machine and the incinerator, controls the input state of garbage according to the combustion state of the incinerator, and controls the garbage input state under optimal conditions. The object of the present invention is to provide a processing device capable of incinerating waste.

Detailed introduction 1 of the present invention will be explained below based on an embodiment shown in the attached curved surface.

In FIGS. 1 to 31, A is a rotary drum type garbage storage/discharge machine, and B is a batch type garbage incinerator.

Garbage storage/discharge fffl A is a rotary drum type in which a rotary drum 2 supported horizontally on a base 1 is rotated forward and backward by an appropriate drive mechanism.
As shown in the figure, a spiral blade 3 is provided, and a support frame 4 on the rear end of the base 1 is provided with an opening/closing door 5 for the garbage inlet at the rear end of the drum 2. 6 is provided with a discharge valve 7 for opening and closing the dust discharge l] at the front end of the drum 2.

The batch type garbage incinerator B has a cylindrical garbage receiving port 12 on the rear part of a furnace body 11 having a fixed hearth, and a chimney 13 on the front part of the furnace body 11. A funnel-shaped chute 14 is provided at one end of the receiving port 12, and the chute 14 is configured to receive the garbage discharged from the discharge port of the rotary drum 2.

An upper gate 15 and a lower gate 16 are provided above and below the garbage receiving port 12, respectively. In addition, a level detector 19 is installed in the upper part of the intake port 12 to detect when the level of the dust 18 on the lower gate 16 has reached a certain level. A transmitter 20 that sends light beams, radio waves, etc. to the opposite side 1i (0) is provided.

The discharge valve 7 and the lower gate 15. , '16 is driven by power such as an electric cylinder, and these exhaust devices and combustion equipment 79 such as the auxiliary burner of the rotary drum 2 and incinerator B are automatically operated by sequence control as described later.

That is, as shown in the block diagram of FIG. 4, there are a drive unit 21 that rotates the drum 2 forward, reverse, and stops, a drive unit 22 that opens and closes the discharge valve 7, and a drive unit 2 that opens and closes the upper gate 15.
3 and a drive unit 24 for opening and closing the lower gate 16 are connected to an output port of a control circuit 26 such as a microcomputer via an interface 25.

In addition, a detector 31 for operation, stop, forward rotation, and reverse rotation of the drum 2 is provided.
, a detector 32 that detects whether the discharge valve 7 is fully open or fully closed, a detector 33, 34 that detects whether the upper and lower gates 15, 16 are fully open or fully closed, the level detector 19, the push The interface 35 includes a button-type start switch 45, etc.
The input port of the control circuit 26 is connected to the input port of the control circuit 26 via.

On the other hand, the batch type garbage incinerator B is equipped with an internal temperature sensor 38 and a drive section 39 such as a preliminary combustion device such as a gas burner and an exhaust device, and the temperature sensor 38, push button type start switch 46, etc. The drive unit 39 is connected to an input port of the control circuit 26 via an interface 40 , and the drive unit 39 is connected to an output port of the control circuit 26 via an interface 41 .

Next, the operation of the garbage disposal apparatus of the present invention will be explained based on the flowcharts shown in FIGS. 5 and 6.

First, when the start switch 45 of the garbage storage and discharge machine A is pressed for a short time under the condition that the second part of the lower gate 16 and the inside of the furnace body 11 are empty, a signal is manually input to the OR gate 27 in the control circuit 26. At this time, if the detector 19 does not detect any dust on the lower gate 16, the dust is not full, so a signal is output from the control circuit 26 to the drive unit 23.
Upper gate 15 is opened.

When the detector 33 detects that the upper gate is fully open, the upper gate 15 is stopped by a signal from the control circuit 26, and at the same time the discharge valve 7 is opened by the drive unit 22. When the detector 32 detects that the discharge valve 7 is fully open, a signal from the control circuit 26 causes the discharge valve 7 to stop at the fully open position, and at the same time the control circuit 26 outputs this signal to the drive unit 21, causing the drum 2 to rotate forward. Start.

When the drum 2 starts normal rotation, the dust in the drum 2 is sent forward by the rotary blades 3 and discharged into the chute 14 from the discharge port. The ejected dust remains on the closed lower gate 16, but when this dust 18 reaches the level of the detector 19 as shown in Fig. 2, or when the drum 2 rotates for a certain period of time. When detected by the timer in the control circuit 26, a stop signal from the control circuit 26 is outputted from the OR gate 28G to the drive section 21, and the drum 2 is stopped.

When the timer in the control circuit 26 detects that the drum 2 has stopped for a certain period of time, a reversal signal is output to the drive unit 21 and the drum 2 is reversed.
stops, and at the same time the discharge valve 7 is closed. When the detector 32 detects the closure of the discharge valve 7, a signal from the control circuit 26 causes the discharge valve 7 to stop at the closed position, and at the same time, the upper gate 15 is closed. When it is detected that the upper gate 15 is fully open, the second gate 15 stops at the fully open position, completing the discharge of garbage from the drum 2, and a signal is output to the AND gate 29, which also outputs a signal to the Iir No. is also output to the AND gate 30 in FIG.

Then, the garbage input signal from incinerator B is sent to AND gate 2.
When input to the other input boat of 9, the bottom? 315 gate open signal is output to the drive unit 24 and lower 1415 gate 1
6 is opened, and the waste on the lower gate 16 is thrown into the furnace body 11. The detector 34 detects that the lower gate 16 is fully open, and after the lower gate 16 has stopped at the fully open position for a certain period of time,
A signal from the control circuit 26 causes the lower gate 16 to close and, when all islands are detected, to stop the lower gate 16 in the fully open position.

In this state, press the work end switch such as a manually operated push button switch, or if the garbage on the lower gate 16 does not become full even after a certain amount of time has elapsed while the garbage is being discharged from the drum 2 as described above. Assuming that drum 2 is empty, press O.
The work is completed by R gate 36.

In the Komi incinerator B, when the start switch 46 is pressed for a short time, a signal is output from the pottery making circuit 1 circuit 26 to the drive unit 39, and operation 71"l#r is turned on. By turning on the operation preparation, the pre-combustion device and exhaust gas are turned on. When the device starts operating and is ready for operation, a signal is output from the OR gate 37 to the AND gate 30.

At this time, if a signal indicating that garbage can be thrown from the drum A side is input to the AND gate 30, the AND gate 30 outputs a garbage throwing signal to the drum, and as described above, the lower gate 16 is opened and closed by opening and closing the lower gate 16. The garbage on top is furnace body 11
It is put inside. It is determined that garbage has been thrown into the furnace body 11 by the completion of a series of opening and closing operations of the lower gate shown in FIG.

In the furnace body 11, preparations for incineration have been completed by operating the pre-combustion device, etc., so the thrown garbage immediately starts burning. The temperature inside the furnace body 11 is initially low, but once the combustion of garbage begins, the temperature gradually begins to rise, and after the combustion progresses and the temperature reaches its maximum, the amount of combustible matter decreases and the temperature begins to drop.

In this way, when the temperature starts to drop, the timer is set to operate, and the temperature detector 38 inside the furnace body 11 is thereby activated, and the work is completed when the temperature detected by this detector 38 falls to a predetermined value. decides whether to proceed.

That is, at the time of the above determination, when it is determined that the inside of the drum 2 is empty because the area above the lower gate 16 is not full even if the drum 2 is operated for a certain period of time as explained in the flowchart of FIG. Or, even if there is garbage remaining in the drum 2, the incineration will be stopped when the working time is over, so if you press the incineration end switch such as a push button switch, the incineration end signal will be output from the OR gate 43, and the blower or Post-processing will be performed, such as stopping the auxiliary burner, and once the post-processing is completed, the incineration work will be completed.

In addition, if the temperature inside the furnace has fallen to the set temperature of the detection company 38, but the incineration work time has not ended, and there is still a considerable amount of trash in the drum 2, the drum continues to rotate forward to eject trash at a constant rate. Because the garbage on the lower gate 16 becomes full before the incineration process is completed, the incineration process is not completed and the flowchart is reached!・
The process returns to the beginning and the incineration process is repeated.

Incidentally, the garbage can be thrown into the rotary drum 2 at any time by opening and closing the opening/closing door 5, regardless of the operation of discharging the drum 2 described in +>iJ. This may be done by opening the closed door 5 and putting in the waste manually, or by using a reversing machine to put the waste in a dust box (not shown).

As described above, this invention combines a rotary drum type garbage storage/discharge machine and a garbage incinerator, and detects the operating state of the incinerator based on the temperature inside the incinerator, thereby controlling the operation of the rotary drum. This reduces the temperature changes in the incinerator, making it possible to incinerate waste automatically and extremely efficiently compared to the traditional incineration of small-scale waste that relies on cans. It is. Although the embodiment uses a batch-type garbage incinerator, the present invention can also be implemented in a large-scale continuous combustion type garbage incinerator.
