BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a coarse crushing type dusting device having a bag-breaking function with an excellent bag-breaking performance for quantitatively supplying incinerator waste to a refuse incinerator, and more particularly to a stable waste incinerator. The present invention relates to a coarse crushing type dusting device having a bag breaking function and an unsuitable object discharging function for enabling continuous operation.

2. Description of the Related Art As is well known, waste that is carried into an incineration facility for municipal waste and incinerated is compared with combustible materials (usually packed in bags) containing food waste discharged from ordinary households. Large-sized waste wood, etc. To incinerate such waste that has been carried in at municipal waste incineration facilities, use a dusting device with a bag-breaking function that can roughly crush the waste to a size that does not interfere with it in advance and that can supply it quantitatively without interruption. It is necessary to supply to the refuse incinerator. A dust-feeding device having such a bag breaking function is disclosed in, for example, Japanese Utility Model Application Laid-Open No. 4-5584 filed by the applicant of the present application.

A dust supply device (garbage supply device) having a bag breaking function will be described below with reference to FIG. 11 which is a cross-sectional view for explaining the structure of a dust throwing device for temporarily storing the dust supplied by a garbage crane (not shown). Is provided with a hopper 2 for, and at the bottom of the hopper outlet 2a of the hopper 2,
A pusher 3 is provided which pushes out the dust t into the dust passage 1a by the operation of the pusher operating cylinder 4. Also,
At the dust outlet of the dust passage 1a, there is provided a pressing plate 10 having a concave curved surface whose upper end is swingably supported by a pin, which enhances the material sealability of this portion and increases the hopper. The amount of external air flowing into the waste incinerator from 2 is reduced. Furthermore, garbage passage 1
Below the waste outlet of a, the trash bag containing the trash (hereinafter referred to as bag trash) pushed out from the trash outlet by the pusher 3 is crushed, and the crushed waste is roughly crushed and quantified. A duster unit, which will be described later, is provided to supply the waste to the refuse incinerator. This dust-feeder unit is crushed by a uniaxial type crushing rotor 5 which is rotated at a low speed of 1 to 2 rpm by a hydraulic motor (not shown), and the crushing rotor 5 interacts with the crushing bag to crush and crush the bag and remove it. It is composed of a support base 7 for roughly crushing dust.

More specifically, the crushing rotor 5 is composed of a plurality of annular support bases 6 set at equal intervals on the outer periphery of a uniaxial drum at a pitch of 150 mm, and a plurality of rotary blades 6a integrally formed therewith. The crushing rotor 5 is configured to rotate in a direction opposite to the flow of incineration waste pushed out from the outlet of the waste passage 1a. On the other hand, the support base 7 is provided directly below the dust outlet of the hopper 2, the upper end of which is supported by a pin, and the lower end of which the tip of the rod of the hydraulic cylinder 8 is pivotally attached, and the rod expands and contracts. The distance between the crushing rotor 5 and the crushing rotor 5 is adjusted by. Also,
A rectifying body 12 which is reciprocated by a hydraulic cylinder 14 arranged in parallel with the support base 7 is arranged on the upper side of the support base 7. Furthermore, triangular fixed blades 7a and 7b for the purpose of coarse crushing are provided in upper and lower two stages on the lower side.

Therefore, the bag dust supplied to the dust feeder is caught by the rotary blade 6a, and the amount of dust is limited by the distance between the concave curved surface 12a at the tip of the rectifying body 12 and the crushing rotor 5. First, the bag-breaking blade 13 provided on the tip end side of the rectifying body 12 breaks the bag dust. After that, the incinerated waste such as the bag waste that has been crushed is crushed by the rotor 5, the fixed blade 7a,
By being subjected to compression and shearing action with 7b, coarse crushing of large-sized waste including disintegration of broken bag waste (removal of contents) is performed. Next, the crushing rotor 5 rotates to quantitatively discharge it to the outside of the machine, and the discharged waste is supplied to a waste incinerator (not shown) from a supply chute provided under the dust supply unit. When an unsuitable substance such as a propane cylinder which is not suitable for crushing is mixed in the crushing rotor 5, the supporting table 7 can be largely retracted to take out the unsuitable substance to the outside of the system in a short time.

[0006]

As described above, in the dust feeding apparatus according to the conventional example, the incineration dust supplied to the dust feeding machine portion including the crushing rotor and the support is pushed out from the outlet portion by the pusher. After moving along the sloping surface of the rectifying body provided on the upper side of the support table located just below the outlet section, the crushing rotor is rotated in the direction opposite to the flow direction of the incineration waste, so that the rectifying body becomes concave. It is captured between the curved surface and the crushing rotor. However, when a part of the incineration waste supplied to the dust collector was not captured between the concave curved surface of the rectifying body and the crushing rotor and remained on the inclined surface of the rectifying body, it was pushed out by the pusher after that. The incinerated waste will be fed over the remaining incinerated waste and supplied to the duster unit, and this incinerated waste is preferentially taken in by the crushing rotor, so the duster is compressed while compressing the residual waste. Supplied to the department. Therefore, the incineration waste remaining on the rectifying body is repeatedly consolidated by the new incineration waste continuously supplied to the duster unit, and is accumulated,
Since the rectifying body grows as if it had grown and hinders the ingestion of incineration waste, not only does the amount of waste processed by the dust-rejecting machine part decrease, but the bag waste in the incineration waste is compressed excessively. Since it is taken in by the machine part, the contact length between the dust bag and the bag breaking blade becomes short, and the bag breaking performance deteriorates.

Further, since the bag-breaking blade, which is mainly intended to break the bags of the garbage during the incineration, is integrally formed with the rectifying body as described above, the bag-breaking blade entangled with the blade surface of the bag-breaking blade. Unable to remove incineration waste such as plastic bags during the operation of the dust collector, and the bag-breaking performance (bag-breaking ratio) drops to about 50% about 20 minutes after the operation starts. There is also a problem to be solved that the frequency of supplying bag waste of bags to the waste incinerator increases, the fluctuation of the waste supply amount increases, and the quantitative supply performance deteriorates.

Further, in the case of the sealing press plate for the purpose of reducing the amount of external air flowing into the refuse incinerator from the hopper, the size of the incinerated refuse pushed out from the outlet by the pusher is φ400 to φ500 mm. ,
The opening size of the outlet is, for example, 1.15 m width × 0.8 height.
There is also a problem to be solved that the material sealing effect due to incineration waste is low because it is ~ 0.9 m, which is much larger. Of course, it is possible to enhance the material sealing effect by reducing the opening size of the outlet part, but relatively large incineration waste such as waste wood in the incineration waste is between the pusher and the top plate of the waste passage. It is not preferable because it becomes trapped and becomes difficult to discharge or causes troubles such as deformation of the top plate.

Therefore, an object of the present invention is to reliably prevent a decrease in the amount of waste treated, a decrease in bag-breaking performance, and a change in the amount of refuse supplied, and to enable the stable operation of the refuse incinerator to continue. The present invention is to provide a coarse crushing type dusting device having a material crushing function and an unsuitable material discharging function.

[0010]

In order to solve the above-mentioned problems, the main means adopted by the coarse crushing type dust-feeding device having the bag breaking function and the inappropriate substance discharging function according to claim 1 of the present invention are:
On the lower side of the hopper for incineration waste input, a pusher for pushing the incineration waste supplied from the hopper into the waste passage by forward and backward movement is provided, below the waste outlet of the waste passage and around the outer circumference. A plurality of rotary blades are provided at a predetermined interval, and a crushing rotor that rotates in the same direction as the dust passing direction is provided.The lower part of the crushing rotor is in front of the dust outlet and is close to the rotary blade of the crushing rotor. A fixed blade support base is provided, and a rectifying body is provided above the fixed blade support base, and a bag-breaking blade capable of swinging about a horizontal axis parallel to the rotation axis of the crushing rotor near the lower end of the rectifying body. Is provided to face the crushing rotor, and a plurality of fixed blades are provided to face the crushing rotor below the bag crushing blade.

Further, the main means adopted by the coarse crushing type dust feeder having the bag crushing function and the inappropriate substance discharging function according to the present invention is the coarse crushing type having the bag crushing function according to claim 1. In the dust feeding device, the rectifying body is configured to be able to move up and down, and a shape of a tip end of the rectifying body facing the crushing rotor is curved and formed in an arc shape around a rotation center of the crushing rotor. To do.

Further, the main means adopted by the coarse crushing type dust-feeding device having the bag breaking function and the unsuitable object discharging function according to claim 3 of the present invention is the rough bag breaking function of claim 1 or 2. In the crushing type dust collector, the horizontal axis of the swing shaft is swung above the dust outlet of the dust passage, and the dust outlet side moves up and down according to the amount of incinerated waste to pass through. It is characterized in that an adjustment mechanism for changing the opening area of is provided.

Further, the main means adopted by the coarse crushing type dust-feeding device having the bag breaking function and the inappropriate substance discharging function according to claim 4 of the present invention is the bag breaking function according to claim 1, 2 or 3. In the coarse crushing type dusting apparatus having, a vibrating conveyor oscillating with an amplitude of 25 to 35 mm is arranged in a discharging portion which is provided below the crushing rotor and discharges the crushed waste into a waste incinerator. .

[0014]

According to the coarse crushing type dusting apparatus having the bag breaking function and the unsuitable material discharging function according to the first aspect of the present invention, the crushing rotor is rotated in the same direction as the direction of the incinerated waste, and the waste outlet is provided. Since the rectifier is provided in front of the rectifier, the incineration dust pushed into the trash passage by the pusher is supplied to the crushing rotor position of the dust collector unit in a free fall state without being obstructed by the rectifier. Then, the incinerated waste is taken in smoothly and surely by the crushing rotor which is rotated in the same direction as the flow direction of the incinerated waste. On the other hand, for example,
Even if the incineration waste pushed out by the pusher to the dust collector is not taken into the shredder rotor, the shredder rotor is rotated in the same direction as the flow direction of the incinerator waste, and the incineration waste from the lower side is preferentially taken in sequentially. Be done. In addition, since a bag-breaking blade that can swing about a horizontal axis parallel to the rotation axis of the crushing rotor is provided facing the crushing rotor, swing the bag-breaking blade during operation of the dust feeder. As a result, incineration dust such as a vinyl bag that adheres to the blade surface of the bag-breaking blade and is entangled is removed from the bag-breaking blade, and is roughly crushed by the plurality of fixed blades. Then, for example, when an unsuitable material for crushing such as a propane cylinder is found, it can be discharged outside the system by largely separating the fixed blade support from the crushing rotor.

According to the coarse crushing type feeding apparatus having the crushing bag function and the unsuitable object discharging function according to the second aspect of the present invention, in addition to the function according to the first aspect, it is possible to vertically move the crushing rotor facing the crushing rotor. Since the shape of the tip of the fluid is curved and formed in an arc shape centering on the rotation center of the crushing rotor, it is possible to effectively rectify the flow of dust without disturbing the flow of dust along the crushing rotor.

According to the coarse crushing type dust-feeding device having the bag breaking function and the inappropriate substance discharging function according to the third aspect of the present invention, in addition to the operation according to the first or second aspect, the dust outlet portion of the dust passage is provided. The opening area of the dust outlet can be changed by vertically moving the adjusting mechanism provided above the container according to the amount of the incinerated dust passing through, so that the material sealing performance can be improved.

According to the coarse crushing type dust-supplying device having the bag breaking function and the inappropriate substance discharging function according to the fourth aspect of the present invention, in addition to the operation according to the first, second or third aspect, the crushed dust is Although it falls from the discharge part onto the vibrating conveyor, even if the crushed dust falls in groups, it is vibrated by the vibrating conveyor, so the group of dust is crushed, dispersed, and conveyed. Moreover, since the vibrating conveyor is vibrated with an amplitude of 25 to 35 mm, which is larger than the amplitude required for the conventional conveyance, the bag debris on the vibrating conveyor is vibrated more greatly and the width direction and the flow direction of the vibrating conveyor are increased. Since it is quickly crushed and dispersed, the lumpy dust that has fallen from the crushing rotor side to the vibration conveyor is made more uniform, and the performance of quantitatively supplying dust to the incinerator is improved.

It is pushed and is quantitatively supplied to the dust feeder B while securing a material seal by incineration waste here.

The dust feeder B is provided with a crushing rotor 5 which will be described later, which is driven at a low speed of 1.0 to 2.0 rpm by a hydraulic drive unit (not shown), and a fixed blade support base provided with a rectifying body and the like. 7 and 7. The crushing rotor 5
As shown in FIG. 2 (a), an annular rotary blade support ring 6 is provided on the outer peripheral portion of a drum that is rotated around the horizontal axis, and is arranged at regular intervals (pitch P ₁ = 150 mm pitch) in the axial direction of the drum. Further, two types of rotary blades 6a and 6b having different blade heights are attached around the outer circumference of the rotary blade support ring 6. As shown in FIG. 2 (b), these rotary blades 6a and 6b include a low rotary blade 6a having a blade height of 50 mm (marked with a cross) and a high rotary blade 6b having a blade height of 80 mm (painting). It has been).

First, bag waste t (φ400 to
The pitch P ₂ of the low rotary blade 6a for taking in (φ500 mm) is about 400 mm, and the pitch P ₃ of the high rotary blade 6b for taking in large dust such as waste wood and coarse crushing is 1200 mm. In addition, the high rotation blades 6b are arranged so that the phases thereof are shifted between the rotation blade support rings 6. In addition, these rotary blades 6a, 6b
The arrangement state of is determined by an empirical rule.

As shown in FIG. 1, the fixed blade support base 7 has two stages of fixed blades 7 protruding toward the crushing rotor 5.
The fixed blade support base 7 is provided with a and 7b, and the fixed blade support base 7 is fixed around the swing center on the side opposite to the fixed blades 7a and 7b by the expansion and contraction of the rod of the hydraulic cylinder 7c provided on the back side thereof. The 7b side is configured to be able to come into contact with and separate from the crushing rotor 5. In addition, the fixed blade support base 7 of the fixed blades 7a and 7b
As shown in FIG. 4, the pitch in the width direction is such that it can move in and out between the rotary blade support rings 6 of the crushing rotor 5,
The pitch is set to 150 mm like the pitch of the rotary blades 6a and 6b.

The incineration waste such as bag waste t pushed by the pusher 3 and discharged to the dust feeder B is directly thrown to the crushing rotor 5 rotating in the flow direction of the incineration waste, and the low rotating blade 6a or the high rotation blade 6a. The crushing rotor 5 is sequentially caught by the rotary blade 6b and moved along the outer periphery of the crushing rotor 5.
And a rectifying body 8 described later.

As shown in FIG. 3, the rectifying member 8 is provided with an inclined surface having an inclination angle α2 ° to 10 ° which comes into contact with incinerated dust such as bag dust moved by the crushing rotor 5, and the crusher is provided on the tip side thereof. The concave curved surface 8a having a radius centered on the rotation center of the rotor 5 is provided so that the incinerated dust taken in is not excessively compacted. And the rectifying body 8
Is a hydraulic cylinder 8 provided on the back surface of the fixed blade support base 7.
It is configured to be moved up and down by c. That is, the rectifying body 8 is lifted when a large amount of dust is supplied, and the gap H between the crushing rotor 5 and the concave curved surface 8a of the rectifying body 8 is increased so that the large amount of dust is easily taken in. ing.

Incinerated refuse such as bag refuse is smoothly supplied between the crushing rotor 5 and the concave curved surface 8a of the rectifying body 8 while the taken-in amount is limited, while the ingested amount is limited. The supplied incineration waste such as bag waste is guided to the bag-breaking blade 9 provided below the rectifying body 8 and having a configuration described later, without being subjected to excessive compaction. This prevents incineration waste such as bag dust from being attached to and accumulated on the rectifying body 8 to prevent a decrease in the amount of waste, and also to incinerate the incineration waste such as bag dust without compressing it. The bag can be supplied to the bag blade 9, and the bag breaking performance can be improved. When crushing unsuitable materials such as a propane cylinder are supplied, the crushing rotor 5 is automatically stopped due to overload, the upper side of the crushing rotor 5 is checked by ITV, and then the fixed blade support base 7 is largely separated from the crushing rotor 5. By doing so, it has a function of discharging unsuitable substances to safely discharge it out of the system.

The details of the bag breaking blade 9 are shown in FIGS.
As shown in FIG. 6, it is provided on the tip end side of the rectifying body 8. The tip portion has a triangular shape suitable for tearing a plastic bag or the like, and the blade surface that comes into contact with the bag dust has a sharp knife edge shape. Also, the bag-breaking blade 9
Is configured to freely swing in and out between the rotary blades 6a and 6b of the crushing rotor 5 by a hydraulic cylinder 9a provided on the back surface of the fixed blade support base 7. In other words, the bag-breaking blade 9
Are arranged so as to be located inside the respective slits 8b having a pitch of 150 mm provided on the tip end side of the rectifying body 8.

Therefore, the bag dust contained in the incineration waste supplied to the bag breaking blade 9 always contacts the blade surface of the bag breaking blade 9, and the bag is torn by the rotating force of the rotary blades 6a and 6b of the crushing rotor 5. Then, the contents are easily taken out. Further, a vinyl bag or the like attached to the blade surface of the bag-breaking blade 9 and entangled can be removed by swinging the bag-breaking blade 9 by the operation of the hydraulic cylinder 9a. As a result, in the conventional case, the bag-breakage ratio was reduced to about 50% about 20 minutes after the start of operation, but it is possible to secure a bag-breakage ratio of 90% or more for a long time. The bag waste in the incinerated waste that has been crushed in this way is taken out by the fixed blades 7a and 7b at the tip of the fixed blade support base 7 and is roughly crushed to the outside of the housing 1. It is discharged and supplied to a refuse incinerator (not shown).

On the other hand, the adjusting mechanism 4 is shown in FIGS.
As shown in (b), the dust passage 1a is provided at the dust outlet portion 1b. One end of the dust passage 1a is supported by a horizontal shaft near the top plate of the dust passage 1a.
The other side of the b side moves up and down, is convex downward, and is a smooth convex curved surface along the flow of dust so that incineration dust such as bag dust pushed by the pusher 3 does not become excessively compacted. "Horizontal" adjustment plate 4a having
And a bending link 4c having pin joints at opposite ends of the upper surface plate and the adjusting plate 4a, and a joint portion having a pin at a substantially central portion, and the upper surface plate and the bending link 4c. The end is pivotally connected to the joint of the coil spring 4
and a pressing mechanism 4b provided with s.

As described above, the adjusting mechanism 4 is capable of performing a follow-up operation of freely moving up and down by the coil spring 4s that expands and contracts according to the amount or size of the incineration dust pushed by the pusher 3 and the compaction state. Therefore, when the incineration waste is not supplied, it is set to a predetermined lower limit position and the waste outlet 1b of the waste passage 1a is set.
It is possible to minimize the opening area of the incinerator, and when the incinerator is supplied, it is possible to reliably discharge the incinerator while ensuring the material sealing function at all times. The amount of air can be reduced.

By the way, the amount of air per hour flowing into the refuse incinerator from the refuse outlet 1b having an opening size of 0.85 m in height and 1.15 m in width, the average flow velocity of the inflowing air is 1.2 m. / Sec, and the average temperature of air is 40 ° C., and the trial calculation is as follows. First, in the past, 0.85 × 1.15 × 1.2 × 3600 (273+
40) / 273 = 4841 Nm ³ / h, whereas in the present embodiment, the height of the dust outlet portion 1b in normal use is 0.
Since it will be 35 m, 0.35 × 1.15 × 1.2 × 36
00 (273 + 40) / 273 = 1993 Nm ³ / h, and the amount of air flowing into the refuse incinerator per hour is 50% or less of the conventional value.

Further, as shown in FIG. 1, the crushing rotor 5
A slanted state in which the conveyance destination side of the waste that communicates with the waste supply port of the waste incinerator (not shown) via the bellows 10 to the discharge portion 1o for discharging the crushed waste below the fixed blade support base 7 is slightly lowered. Thus, the vibration conveyor 11 is connected.
The vibration conveyor 11 is configured to be vibrated by the operation of the inverter motor 11a with an amplitude of 25 to 35 mm, which is larger than the standard amplitude of about 15 mm as a conventional vibration conveyor.

Therefore, even if the crushed waste falls in groups, the vibration of the vibrating conveyor 11 crushes and disperses the group of wastes and supplies them to the refuse incinerator. Quantitative supply performance is improved. For example, the amplitude of the vibration conveyor 11 is plotted on the horizontal axis, and an instantaneous excessive supply (200
As shown in FIG. 8 which is an explanatory diagram of the state of disintegrating and dispersing dust with the frequency of (% or more) as the vertical axis, the frequency of 32 mm is the least frequent, and the frequency is high when the amplitude is less than 32 mm or greater. From the viewpoint, it can be seen that the crushing and dispersing performance of dust is excellent when the amplitude is in the range of 25 to 35 mm.

As described above, when the vibration amplitude of the vibrating conveyor 11 is set in the range of 25 to 35 mm, the dust is effectively crushed and dispersed because the larger amplitude causes the supplied bag-breaking dust to vibrate greatly. It can be understood that a large lump of dust is dispersed in the width and the front-back direction of the vibration conveyor 11. As a result, the performance of quantitatively supplying the dust of the coarse crushing type dusting device is significantly improved, and
It becomes possible to continue to supply waste to the incinerator even if unsuitable substances are discharged from the system.

As described above, according to the coarse crushing type dusting apparatus having the bag breaking function according to the present embodiment, the incineration waste pushed out by the pusher 3 is not disturbed by the rectifying body 8 and the dust in the dusting machine section B is prevented. The incineration waste is supplied to the position of the crushing rotor 5 in a free-falling state, and the incinerator waste is smoothly and surely taken in by the crushing rotor 5 that is rotating in the same direction as the flow direction of the incinerator waste. And the reduction of the amount of waste disposal is prevented, and the fluctuation of the amount of incineration waste supplied to the waste incinerator is also eliminated. further,
By swinging the bag-breaking blade 9 around the horizontal axis, it is possible to remove from the bag-breaking blade 9 incineration dust such as a vinyl bag attached to the blade surface of the bag-breaking blade 9 and entangled.
The excellent bag-breaking performance is maintained for a long period of time, and the excellent material sealing property can be maintained by the adjusting mechanism 4, so that it has a great effect on the continuous stable operation of the refuse incinerator.

Incidentally, the coefficient of variation in the load rate (%) of the waste supply amount (the rate of change in a short time with respect to each supply rated amount) is the coarse crushing type supply having the bag breaking function according to the above embodiment of the present invention. FIG. 9 is an explanatory diagram of the dust variation coefficient in which the case of the dust device is shown by a white circle and a solid line, and the case of the conventional coarse crushing type dusting device described based on FIG. 11 is shown by a black circle and a broken line. According to this figure, when the load factor is less than about 150%, it can be clearly seen that the coefficient of variation is smaller and the quantitative dust feeding performance is more excellent in the present embodiment than in the conventional case.

Next, referring to FIG. 10 which is a sectional configuration explanatory view of an adjusting mechanism, a coarse crushing type dusting apparatus having a bag breaking function and an unsuitable object discharging function according to another embodiment of the present invention will be described. Only the different points will be described below. The difference between the present embodiment and the above embodiment is the difference in the operating mechanism of the adjusting plate 4a. That is, while the adjusting plate 4a according to the above-described embodiment is swingably supported by the pressing device 4b and the bending link 4c, in the present embodiment, the bracket 4d is provided outside the top plate of the dust passage 1a. The pressing mechanism 4b has one end side pivotally attached to the protruding bracket 4d, and the other end side of the pressing mechanism 4b penetrates the top plate, and the penetrating end is connected to the adjusting plate 4a by a pin.

Therefore, as in the case of the above-described embodiment, the pressing mechanism 4b that expands and contracts according to the amount or size of incinerated dust and the compaction state causes the dust outlet 1b side of the adjusting plate 4a to move up and down. The effect is the same as in the above embodiment.

[0038]

As described above in detail, according to the coarse crushing type dusting device having the bag breaking function and the unsuitable object discharging function according to the present invention, the incinerator waste pushed out by the pusher is obstructed by the rectifying body. It is supplied to the position of the crushing rotor without dropping, and the incinerator waste is smoothly and reliably taken in by the crushing rotor that is rotating in the same direction as the flow direction, so there is no compaction / accumulation as in the past.
A reduction in the amount of waste treated is prevented, and fluctuations in the amount of incinerated waste supplied to the waste incinerator are eliminated. Furthermore, by rocking the bag-breaking blade around the horizontal axis, it is possible to remove incinerated dust such as vinyl bags that are attached to the blade surface and entangled with the blade surface from the bag-breaking blade. While being maintained for a long period of time, the adjusting mechanism can keep the excellent material sealing property. Therefore, the problems of the coarse crushing type dust feeder according to the conventional example, that is, the problems such as the reduction of the amount of waste processing, the deterioration of the bag breaking performance, the variation of the amount of waste supply, and the poor material sealing function are all solved. Therefore, it has an extremely great effect in continuing the stable operation of the refuse incinerator.
