Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to a device for conveying shredded waste with relatively strong cohesiveness, and in particular, the present invention relates to a device for conveying shredded waste that has a relatively strong cohesive force, and in particular, for transporting shredded waste placed in a hopper to an incinerator or a classifier. The present invention relates to a crushed garbage conveying device such as a conveyor with a hopper that narrows the conveying path in the middle of the conveyance because the area of the outlet for the crushed garbage is much smaller than the receiving area.

[Prior Art] In general, raw garbage such as municipal garbage is collected, temporarily stored, and then crushed using a crusher or the like and then incinerated.

For example, a shredded waste transport device is used to transport trash crushed by a crusher, etc. to an incinerator or classifier, and the shredded trash is sequentially dropped into the hopper of this transport device using a crane, etc. For example, an apron conveyor provided at the bottom of the hopper sequentially transports the crushed waste toward the incinerator.

Incidentally, there will be no problem even if the amount of shredded waste input into the hopper varies, but since a large amount is input by a crane, etc., it is necessary to transport it to the incinerator at the transport end using a conveyor in order to stably incinerate it. A need arises to keep the amount constant in small amounts at all times.

For this reason, as shown in FIG. 1, a shovel bar 4 is provided at the inclined entrance 2 of the apron conveyor 1 equipped with a scraping plate so as to cross the interior of the hopper 3 at right angles to the flow direction of the waste. Attempts have been made to limit the amount of garbage conveyed, and also provide a weir plate 7 on the slope 6 of the conveyance path 5, so that the layer of garbage to be conveyed out has a predetermined thickness and is conveyed quantitatively.

[Problem to be solved by the invention] However, in the above case, shredded waste 1
0 will move in the transport direction as a whole, and this will push into the inclined entrance 2 all at once, and some of the garbage will be pushed back into the hopper 3 by the weir rod 4 and compacted.
Not only does a bridging occur here, but more than a predetermined amount of garbage flows into the slope 6, and the remaining garbage that cannot fit in at the weir plate 7 is compacted, causing a bridging phenomenon in this area as well, causing the garbage to be transported. I had the inconvenience of not being able to do it. That is, after the garbage was compacted, only the lower part near the conveyor 1 was scraped off by the conveyor 1, and the upper part of the garbage was left hanging on a shelf.

Therefore, in order to correct the above-mentioned inconvenience, as shown in FIGS. 2 and 3, resistance plates 12 made of equilateral angle-shaped steel having the same shape are installed on the inner wall 11 of the hopper 3 in a staggered manner along the garbage transport direction. Attempts have also been made to control the movement of garbage by placing it in place.

However, in this case, since the shredded waste has a strong binding force, the movement of the part of the waste that is in contact with the resistance plate 12 is restricted at that location, but the movement of the part of the waste that is in contact with the resistance plate 12 is restricted at that location, but the movement of the waste in the part that is in contact with the resistance plate 12 is restricted at that location, but the Since the garbage moves a lot, and as a result, the entire garbage is transported in a meandering manner, a lot of garbage still flows into the inclined entrance 2 and the inclined part 6, causing clogging and bridging, which cannot be fundamentally solved. It's not working.

Further, a hopper device is reported in Japanese Utility Model Publication No. 1982-46682.

In the hopper device of the publication, a conveyor belt is provided in the bottom of the hopper so as to cross the bottom of the hopper, and on this conveyor belt, compartments are formed at predetermined intervals on horizontal bars. It is also recognized that the hopper is provided with partition walls at predetermined intervals in the conveying direction of the conveyor belt.

However, the partition wall is attached to the hopper so as to cross the entire width of the conveyor belt in order to divide the bottom discharge port of the hopper into a plurality of parts along the conveyance direction of the conveyor belt. Therefore, although the partition wall forms a plurality of discharge ports and can certainly fill each compartment of the conveyor belt with objects to be transported, when the objects are inputted from the upper input port of the hopper, There is a problem in that the liquid must be uniformly fed into each divided outlet.

Furthermore, Utility Application No. 1983-26379
131286), Hotupa was reported.

Although this hopper does have ridges on the inner wall of the hopper, these ridges are only provided to guide the glass bottle that is put into the hopper in the direction of gravity.

This invention was devised to effectively solve the above-mentioned problems, and its purpose is to create a hopper that accepts and temporarily stores shredded waste with strong cohesiveness and cuts it out in small quantities. Baffle plates are provided on the inner wall at predetermined intervals along the direction of transport of the waste, and the area for regulating the movement of the waste is gradually enlarged, so that the cross-sectional area of the transport path is gradually reduced. To provide a crushed waste transport device capable of quantitatively transporting waste without causing clogging or bridging.

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a shredded waste transport device that quantitatively transports shredded waste with relatively strong cohesion toward an incinerator, etc. A conveyor provided facing the conveyance end side to form a continuous conveyance path of a predetermined length, and a conveyor that sequentially expands along its longitudinal direction and upward in order to supply the shredded waste onto this conveyor. A hopper partitioned by a side wall inclined at an angle of repose slightly larger than the angle of repose of the shredded waste to be thrown into the hopper, and a hopper arranged at appropriate intervals along the transport direction of the waste to be thrown into the hopper, facing the inner wall of the hopper. and facing the conveyance path defined by the hopper on the conveyor to restrict the movement of crushed garbage from the upstream side to the downstream side in the conveyance direction. The cross-sectional area of the conveying path is gradually expanded to guide the shredded waste thrown into the hopper in the direction of gravity along the inner wall, and the cross-sectional area of the conveyor path is It is equipped with a plurality of baffle plates that reduce the size in stages.

[Function] The present invention discovers that the problem with the prior art is due to the fact that the amount of garbage that moves laterally within the hopper is large compared to the amount of garbage that is transported due to the strong binding force of the garbage. At the same time, in order to prevent this, the amount of garbage that slides down is regulated so that the amount of garbage scraped by the conveyor is commensurate with the amount of conveyance while keeping the entire garbage in the hopper stagnant. .

Shredded waste is put into the hopper by a crane, etc., and is temporarily stored there and then descends in this hopper one by one, falling onto a conveyor that is driving below, where it is scraped off by the conveyor's scraping plate and transported one by one. It will be transported toward the end, ie, toward an incinerator or the like.

Here, when transporting the waste, the entire input shredded waste tries to move in the transport direction, but
A baffle plate attached to the inside wall of the hopper acts to resist the transport force of the trash and restrict the movement of the trash.
The movement of entire garbage can be regulated. especially,
Since the present invention is intended for crushed waste with strong cohesiveness, the area of the baffle plate is gradually expanded in the conveying direction to gradually increase the ability to restrict the waste.

Although on the surface the garbage whose movement is restricted appears to be stagnant, it is caught up from the tail portion and is conveyed while being gradually broken down.
The amount of garbage scraped off by the conveyor in the area partitioned by the baffle plate sequentially descends along the baffle plate, and is successively scraped off by the conveyor.

The amount of garbage conveyed is particularly controlled by the baffle plate, which forms a layer of garbage with a predetermined thickness and width on the conveyance path on the conveyor, so that a predetermined amount of garbage is always conveyed. can do. In this way, when the tail side of the rearmost baffle plate is cleared, the rubbish that was regulated by the next baffle plate in the transport direction will fall and be transported sequentially, and so on. All the garbage in the hopper will be transported.

[Example] A preferred embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

First, as shown in FIGS. 4 and 5, numeral 13 is a conveyor having a conveyance path 14 of a predetermined length (approximately 10 m), and as this conveyor 13, for example, an apron conveyor with a scraping plate is used. The front conveyance end side of this conveyor 13 is inclined upward, and a weir bar 15 is provided in the middle thereof.
The conveying end 16 is connected to an incinerator, a vibration distributor, etc. (not shown), so that crushed waste can be conveyed to the incinerator, etc., as described later.

The conveyor 13 has a depth of about 3 m and a length of about 5 m to feed crushed waste along its longitudinal direction.
A hopper 17 of about 100 liters is provided. This hoppa 1
7 has a lower end discharge port 18 formed slightly narrower than the width of the conveyor 13, and is sectioned into a funnel-shaped cross section by an inclined side wall 19 that gradually expands upward. An input port 20 is formed.

Further, the angle of inclination of the side wall 19 is formed to be slightly larger than the angle of repose of the shredded waste to be thrown into it, so that the shredded waste can be lowered sequentially along the inner wall 21 as it is transported. There is. Therefore, bridging within the hopper can be prevented by setting the inclination angle of the side wall 19 to a predetermined value.

As shown in FIGS. 6 to 8, baffle plates 22, which are a feature of the present invention, are disposed oppositely to each other on the inner wall 21 at predetermined intervals along the longitudinal direction of the inner wall 21, that is, the direction in which the waste is transported. It is provided. Specifically, in the illustrated example, a total of six baffle plates 22 (3 pairs) are provided with their respective garbage regulating surfaces protruding toward the conveyance path 14 side, and the restriction plates 22 are sequentially disposed along the garbage conveyance direction. The surface area is enlarged. As shown in the figure, the area of the dust regulating surface (see FIG. 6) of the baffle plate 22a located at the most upstream side in the conveyance direction, that is, at the tail portion 23 of the dust, is the smallest.
For example, one side of an angle iron 24 having an L-shaped cross section and having a length of about 1 m and a width of 7.5 cm is welded and fixed along the inclination direction of the inner wall 21 to be firmly attached.

Moreover, the baffle plate 22b (see FIG. 7) located in the center has a length of about 60 mm on the angle iron 24 having an L-shaped cross section.
Auxiliary plates 25 of approximately 1.5 cm in length are welded and fixed in a stacked manner and protruded toward the conveyance path 14, and the area of the garbage control surface is increased to gradually reduce the cross-sectional area of the conveyance path 14 through which the garbage moves. are doing.

Next, the baffle plate 22c (see FIG. 8) closest to the inclined entrance 2 has the above-mentioned baffle plate shape located at the center, and further includes an auxiliary plate with an L-shaped cross section up to the vertical part 26 of the conveyor conveyance path 14. 27 is projected and fixed by welding, and the cross-sectional area of the conveyance path 14 defined by the hoppers 17 on the conveyor 13 is further reduced, and a waste layer of a predetermined thickness and width is formed. It is designed to transport a predetermined amount of waste. In this way, the conveyance path 14
The reason why the cross-sectional area of An excessive load is applied to the baffle plate 22a located on the upstream side of the hopper 17, which not only causes problems in terms of the strength of the hopper 17, but also causes a compaction phenomenon in this area, forming a bridge, which prevents the smooth transportation of waste. This is because it will not be possible. Therefore, as mentioned above, the baffle plate 2
By gradually increasing the area of 2 and gradually reducing the cross-sectional area of the transport path 14, substantially the same weight is applied to each baffle plate 22, thereby restricting movement of the entire garbage in the transport direction.

That is, each baffle plate 22a, 22b of the present invention,
22c gradually expands the movement of waste from the upstream side to the downstream side in the conveyance direction, thereby gradually increasing the regulating force and gradually reducing the cross-sectional area of the conveyance path. As described above, each baffle plate 22a,
If 22b and 22c are formed in the same shape, an excessive load will be applied to the baffle plate 22a located on the most upstream side. This is because if they are made to have the same shape, they must be formed from the beginning to have a large regulation area commensurate with the amount of discharge, and the cross-sectional area of the conveyance path will be narrowed down at once.

In addition, since each baffle plate 22 is provided to be inclined along the inner wall 21, the garbage whose movement in the transport direction is restricted is guided in the direction of gravity along the inner wall 21 and falls onto the conveyor 13. It also has the function of

Although three pairs of baffle plates 22 are provided in the above embodiment, the hopper 1 is not limited to this.
Of course, this can be increased or decreased depending on the capacity of 7.

Next, the operation of the present invention configured as above will be described.

First, as shown in FIGS. 4 and 5, the crushed waste 28 is thrown into the hopper 17 through the waste inlet 20 by a crane or the like (not shown), and is sequentially lowered inside the hopper 17. The particles fall onto the conveyor 13 that is being driven below, and are sequentially transported along the transport path 14 toward the transport end 16, ie, toward the incinerator or the like.

Here, when transporting the trash, the whole of the crushed trash 28 that has been thrown in tries to move in the transport direction, but the baffle plate 28 attached to the inner wall 21 of the hopper
In particular, the inclined portion 29 acts to restrict the movement of the garbage against the transporting force of the garbage, thereby making it possible to restrict the movement of the entire garbage. In particular, since the present invention is intended for shredded waste with strong cohesiveness, the area of the baffle plate 22a located at the tail portion 23 of the waste where load is likely to be applied is minimized, and the area of the baffle plate 22a is minimized in stages as it goes in the conveying direction. Since the baffle plates 22 are enlarged, the dust regulating force is applied almost equally to each baffle plate 22, and no concentrated load is applied to any baffle plate 22.

Although on the surface the garbage whose movement is regulated appears to be stagnant, it is caught up from the tail portion 23 and is conveyed while being gradually broken down.

This phenomenon occurs for the following reasons. Hotupa 17
When crushed waste is thrown into the container, a gravitational force is applied to the entire waste, and a lateral force is applied to the waste near the conveyor 13 located at the bottom due to the scraping force. This lateral force is hopper 1
7, it has priority over the force in the direction of gravity. Therefore, after the lower part of the garbage is transferred laterally by the conveyor 13, the upper part of the garbage is transferred to the conveyor 13.
It will fall on top. Since the empty conveyor 13 always comes to the tail section 23 on the most upstream side in the conveyance direction, the garbage in this section easily falls.

However, since the garbage on the downstream side is transferred from the upstream side by the conveyor 13 that already contains garbage, the force in the lateral direction takes priority over the force in the direction of gravity and cannot fall.

Therefore, the garbage is drawn in from the tail portion 23 and is gradually dismantled while being conveyed.

In this tail portion 23, the amount of garbage that has been caught and transported is removed from the inclined portion 29 of the baffle plate 22.
As a result, they are guided down along the inner wall 21 of the hopper 17 and fall onto the conveyor 13 one after another.

The amount of garbage transported is particularly determined by the vertical portion 27 of the baffle plate 22c located closest to the inclined entrance 2.
A dust layer of a predetermined thickness (approximately 50 cm) and a predetermined width is formed on the transport path 14 on the conveyor 13, and a predetermined amount of trash can be transported at all times. Therefore, in order to change the amount of garbage transported, it is possible to change the number of revolutions of the conveyor 13 or by changing the length and width of the vertical portion 27 of the baffle plate 22c as appropriate.

In this way, when the tail side of the rearmost baffle plate 22a is cleared, the rubbish that was regulated by the next conveyance direction side baffle plate 22b falls and is sequentially conveyed. Thereafter, all the garbage in the hopper 17 is transported in the same manner.

Note that the weir bar 4 provided at the inclined entrance 2 of the conveyor 13 and the weir bar 15 provided at the inclined portion 6 can make the upper surface of the transported waste substantially horizontal. Furthermore, if additional crushed waste is added during transportation, it goes without saying that the added trash will be sequentially transported from the tail section in the same manner as described above.

In this way, the movement of the entire garbage is regulated, and the cross-sectional area of the conveyance path is reduced in stages, so that only a predetermined amount of garbage can be rolled up and conveyed from the tail of the garbage, unlike conventional methods. There is no possibility of clogging or bridging caused by compaction of waste at the inclined entrance of the conveyor.

[Effects of the Invention] In summary, the present invention provides the following excellent effects.

A baffle plate is installed on the inside wall of the hopper that expands step by step along the transport direction of the waste, so that the movement of the highly cohesive crushed waste is restricted and stagnant, and a predetermined amount is removed from the tail part. It is possible to continuously transport small amounts of waste, dramatically improving quantitative supply performance.

Since the movement of the entire garbage in the hopper can be regulated, there will be no consolidation phenomenon of garbage at the inclined entrance of the conveyor, and therefore, it is possible to prevent the occurrence of garbage clogging and bridging that conventionally occur. .

Since no clogging or bridging occurs, continuous and stable operation is possible, and maintenance is also easy.

Since the structure is simple, it can be easily adopted into existing equipment.
