Description

[Detailed Description of the Invention] [Industrial field of application] The present invention is a waste compaction device used for compressing waste and packing it in a container for transportation, etc. The present invention relates to a waste compression device.

[Conventional technology]

Use an air transfer system to collect waste that is placed far away from the waste compression equipment, such as the upper floors of high-rise buildings, or the waste input ports installed in multiple buildings, in a single location for intensive treatment. A garbage compactor is used.

This waste compression device is usually a centrifugal separator 2 provided at the end of an air carrying duct 1 as shown in FIGS. 5 and 6.
And a dust compressor 3 having a hermetic structure connected to the lower part of the separator 2 and the like. The dust compressor 3 has a hollow casing 5 for removably connecting a transportation container 4 to one end thereof. A compression ram 6 slidably fitted inside the compression casing 5, a hydraulic cylinder device 7 for reciprocating the compression ram 6, and the like.
Waste 8 that has passed through the separator 2 and dropped into the compression casing 5
Is pressed by the compression ram 6 (arrow a) and the container 4
It is supposed to be packed inside. In the figure, 9 is a dust inlet provided in the duct 1, 10 is a blower for sucking air in the duct 1, and 12 is a fastening device for connecting the container 4 to the compression casing 5.

[Problems to be solved by the device]

However, the dust compressing device using the above-mentioned air conveying system cannot treat dust that is difficult to convey by air, such as garbage, solids (bottles, metal pieces), corrugated cardboard, etc. A separate type waste compressor (not shown) must be installed separately, resulting in high equipment costs, increased maintenance and inspection of the machine, and replacement and transportation of a full container. There was a problem that the management of the waste disposal work would be troublesome because the waste disposal work would be carried out for two systems.

It seems that this problem can be easily solved by providing an input port for inputting food waste, etc. in the upper part of the dust compressor 3, but a concrete examination reveals that Has a separator 2 attached at substantially the center thereof, and the lower surface of the portion extending from the center to the attachment side end of the container 4 is covered by the lid 13 of the container in an open state. It was difficult to realize, and there was a strong demand for alternative measures to the above.

In view of the above-mentioned problems, the present invention is to provide a refuse compression device that enables manual input of refuse that is difficult to convey by air, such as raw refuse, without significantly modifying the conventional refuse compression device. And

[Means for Solving the Problems]

Embodiments of the present invention will be described below with reference to the drawings. still,
Regarding the reference numerals and symbols in the drawings, the same reference numerals and symbols are used for the portions that perform the same functions as the respective portions of the dust compressing device when the conventional technique is described, and description thereof will be omitted.

1 to 4 show an embodiment of the present invention.
The main part of the device of the present invention is a separator 2 having the same structure as that of the prior art, which separates the waste fed by the air flow, and a waste compressor 3 connected to the lower part of the separator 2 and having substantially the same structure as the conventional one. And the connection flange 22 to the opening 21 provided at the side of the waste compressor 3.
Is connected to the waste compressor 3 and operates in a direction (arrow c) orthogonal to the operating direction of the waste compressor 3 (arrow c). A feeder casing 25 having a hollow structure including 24, a feeder ram 26 slidably fitted in the feeder casing 25, a hydraulic cylinder device 27 for reciprocating the feeder ram 26, and the like.

The feeder ram 26 has three important functions described below. That is, the first is that while the refuse compressor 3 is stopped, the raw garbage 8a introduced into the inside of the feeder casing 25 from the refuse inlet 24 passes through the opening 21 and the compression casing 5
The second part is that the front part of the feeder ram 26 is in the compression casing 5 while the waste compressor 3 is in operation.
Is to prevent the backflow of dust to the feeder casing 25. The third part is that the front part of the feeder ram 26 also forms a side guide of the compression ram 6 so that the reciprocating motion of the compression ram 6 is prevented. In order to achieve the above-mentioned second and third functions, the same number of guide bars 29 as the side guide bars 28 of the compression casing 5 are provided on the front surface of the feeder ram 26. It is fixed to the level and the feeder ram 26
On the piston rod 30 connected to the, a length adjusting mechanism 32 (for example, a screw mechanism is used) near the gudgeon pin.
Is provided so that the front surface of the guide bar 29 is in the same vertical plane as the inner surface of the side guide bar 28 when the piston rod 30 is fully extended. In order to prevent the feeder ram 26 from moving backward during the operation of the dust compressor 3, the hydraulic circuit of the hydraulic cylinder device 27 is provided with a known pressure oil sealing means (not shown). (For example, it is convenient to use a three-position four-way switching valve for the driving hydraulic switching valve of the hydraulic cylinder device 27.) In the figure, 28a facilitates the reciprocating motion of the compression ram 6 at the bottom of the compression casing 5. Guide bar for 2
Reference numeral 8b is a guide bar provided on the upper portion of the compression ram, and the level thereof is set so that the bottom surface of the feeder casing 25 is substantially aligned with the upper surface of the guide bar 28a provided on the bottom portion of the compression casing 5.

In order to use this device, first, the container 4 is connected to the open end of the compression casing 5 using the lashing device 12, the lid 13 of the container is opened and fixed to the lower surface of the ceiling of the compression casing 5, and the feeder casing 25 is used. After closing the upper dust input port 24, the blower 10 (see FIG. 5) is activated to operate the air transfer system. The dust 8 that enters the separator 2 along with the air flow, is separated from the air in the separator 2, and falls into the compression casing 5 is pressed by the compression ram 6 toward the end of the compression casing 5. , Packed inside the container 4.

During operation of the compression ram 6, the front surface of the feeder ram 26 closes the opening 21 of the compression casing 5, so that dust does not flow back into the feeder casing 25, and the front surface of the feeder ram 26 does not flow back. Since the guide bar 29 is provided, the operation of the compression ram 6 is smooth.

When throwing in garbage 8a such as food waste that is difficult to convey by air, after stopping the operation of the blower 10 and the compression ram 6, open the lid 37 of the garbage input port 24 and throw in the food waste 8a to feed the feeder ram 26. To reciprocate. By this operation, the feeder ram 26 presses the garbage 8a and sends it to the inside of the compression casing 5 (arrow d).
The a is packed inside the container 4 by the compression ram 6 which is activated later.

It should be noted that the present invention is not limited to the above-described embodiments, and it is needless to say that various modifications can be made without departing from the gist of the present invention.
