Problems solved by technology

[0006] In addition, when the amount of garbage accumulated in the hopper increases, the garbage at the bottom of the hopper is compacted to increase the specific gravity of the garbage, or the specific gravity of the garbage itself in the hopper increases, the garbage supplied by one action of the pusher will The amount of supply will inevitably increase, and the weight of the garbage supply will fluctuate, causing various problems
[0007] That is, when the supply of garbage is carried out intermittently, or when the amount of garbage supplied per unit time (t / h) fluctuates greatly, the amount of garbage in the garbage incinerator will be uneven and the combustion will be unstable, so the temperature fluctuations in the furnace and the amount of CO Fluctuation, or the cause of unburned substances, or even an increase in the occurrence of dioxins

Embodiment 1

[0046] Figure 4 Shown is a system configuration diagram of a quantitative supply device according to an embodiment of the inventions of Claim 3, Claim 4, and Claim 6.

[0047] In Embodiment 1, the garbage supply device 1 is attached to the bottom of the garbage storage funnel 3 on the motorized grate type garbage incinerator 2 used for burning garbage, etc. The most upstream part of the stepped motorized grate 4 of the row 4b and the post-combustion motorized grate 4c. The refuse supply device 1 is a pusher type device, and it includes a pusher 6 reciprocatingly sliding along the top of a flat plate-like step 5 and a drive mechanism 7 for reciprocating the pusher 6 . In this way, the garbage W thrown in by a crane (not shown) from the top of the hopper 3 sequentially falls on the steps 5, and the garbage on the steps 5 is sequentially given to the drying motor grate 4a by the reciprocating motion of the pusher 6. . In addition, the structure of the motorized grate type gar...

Embodiment 2

[0062] Figure 8 Shown is a system configuration diagram of the quantitative supply device according to the embodiment of the invention of claim 3, claim 5, and claim 6.

[0063] In the second embodiment, the structures of the garbage supply device 1, the garbage incinerator 2, etc. are basically the same as those of the above-mentioned first embodiment. Therefore, the same part as in Example 1 is used with and Figure 8 The same symbols are used, and detailed descriptions thereof are omitted.

[0064] exist Figure 8 In the second embodiment, the support portion 11 of the hopper 3 is provided with a weighing scale (weight measuring device) 12 such as a sensor, and the weight of the garbage in the hopper 3 can be directly measured by the weighing scale 12 .

[0065] In this structure, when the data on the weight of the garbage measured by the weighing scale 12 is input in the controller 9, the controller 9 calculates the garbage supply weight (t / h) per unit time according t...

Abstract

The method of supplying garbage to garbage incinerator is to supply garbage through a tunnel to the garbage incinerator quantitatively for stable combustion, reduced CO generated and preventing the generation of un-combusted matter and dioxin. The garbage supplying device has pushing machine with controlled withdrawing speed faster than pushing speed, CCD camera to monitor the status in the upper part of the garbage tunnel, some unit to calculate the weight of supplied garbage in unit time based on the garbage volume inside the tunnel and garbage weight thrown into the tunnel, and some controller to control the constant garbage supplying amount.

Description

technical field [0001] The present invention relates to the improvement of the garbage supply system attached to the garbage incinerator which mainly incinerates municipal garbage and industrial waste. A waste supply device and a waste supply method for efficiently supplying waste into a waste incinerator by weight (t / h). Background technique [0002] Garbage incinerators for municipal waste and industrial waste have been widely used in the past. The mobile grate type garbage incinerator is equipped with a garbage supply funnel, and the garbage brought in by garbage collection vehicles is picked up by a crane and put into the funnel. Then, the garbage put into the funnel is supplied to the step-type motorized grate in the incinerator in turn through the garbage supply device arranged at the lower part of the funnel. [0003] As the above-mentioned garbage supply device, although various forms of devices have been developed, most of the motorized grate-type garbage incinera...
