Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a storage and discharge device for municipal waste.

[Prior Art] A vacuum collection and transportation system for municipal waste generally consists of a collection station that is equipped with a separator, etc., to collect, separate, store and discharge incoming waste; 3: a transport pipe for carrying and transporting the waste, and a storage and discharge device for storing the thrown garbage and discharging it into the transport pipe.
It consists of two main parts.

Among these storage and discharge devices, conventionally there are a dust chute type and a ground input type, as schematically shown in FIG.

In the dust chute method, dust chute b is provided with a garbage input port C@ for each Mll of building a, and the lower end of dust chute b is connected to pipe chute storage tank d or large capacity storage tank 0 installed underground. The garbage inputted from the port C is stored in the storage tank d or e, and the stored garbage is allowed to fall into the transport pipe g when the discharge valve t is opened.

The above-ground input method is a type in which an input port is provided above ground, this input port is connected to a pipe chute storage tank d installed underground, and the storage tank d is connected to the transport pipe 0 via a discharge valve. belongs to.

In the figure, l is the storage tank pit, j is the intake valve, and k is the intake cylinder.
is an inspection pit, ■ is an inspection port.

In the above-mentioned conventional storage and discharge device, when garbage is input from the input port C or h in the form of a plastic bag, paper bag, or in loose pieces, the garbage is temporarily stored in the storage tanks d and e.

Next, to start transport, start the blower at the collection station, and open the intake valve j of the transport pipe g where the relevant storage tank is located.
By opening the waste, an air flow necessary for transporting the waste is generated, and then the discharge valve f of the storage tank to be transported is opened to allow the waste to fall into the transport pipe 0.

In this case, in the case of the pipe chute storage tank d, the garbage stored above the discharge valve f falls into the transport pipe Q due to gravity and is transported by the air flow, and the garbage in the plastic bag or paper bag is removed. It will be broken up and sent to a collection station.

In the case of a large-capacity storage tank e, if the storage tank is a rotating drum type, open the lid and rotate the drum, or if the storage tank has a rotating blade, rotate the blade. As a result, each of the stored garbage is discharged to the discharge valve f side, and is transported inside the transport pipe 0 in pieces as in the case of the pipe plate storage tank.

However, in the conventional method described above, ■ The diameter of the transport pipe is generally 4.
The size of the pipe is between 00 and 500φ, and the waste is transported in pieces through this pipe, so the wind speed inside the transport pipe must be increased, which requires a large amount of air and requires a large amount of power.

■ Garbage that is input and discharged includes kitchen waste, items with a high moisture content,
This includes items with strong odors such as fish, food scraps, paper, glass bottles, cans, and plastics, which are mixed with air and sent to the collection station at the end of transportation, where the stench from the blower exhaust is emitted. A huge improvement in deodorizing equipment! Additionally, deodorizers must be replaced regularly, which increases maintenance costs.

■ The interior of the transport pipe is exposed to dirt from the waste, and the pipe corrodes due to this, so it is necessary to make the corrosion type thicker for the length of its service life.

■ Since glass, sand, and other hard materials are transported through the transport pipe at a speed of I'h, it is necessary to add extra allowance for wear and tear due to abrasion and collisions when planning.

■ The area near the garbage inlet (garbage storage tank) has a foul odor, which is unfavorable from an environmental perspective.

■ Since the component equipment at the collection station, such as separators, pack filters, blowers, deodorizing devices, silencers, and storage buildings, has a large capacity and is large in size, construction costs increase accordingly, and operation and maintenance costs also become relatively high.

■ Since it is transported in bulk within the transport pipe, the energy required is approximately 100,000 yen even for the same pipe diameter, and the wind speed is 200 yen.
The speed is as high as ~35 m/s, making it impossible to save power.

There were many problems such as.

[Object of the invention] The present invention aims to reduce the size of the waste storage section, prevent bad odors, automate a series of operations, reduce transportation power through encapsulation, save energy, and further improve related equipment (transport side 1).
The aim is to downsize the

[Configuration of the Invention] The municipal waste storage and discharge device of the present invention comprises a garbage bag for storing thrown garbage, a compression device for compressing the garbage in the garbage bag, an inner cylinder for protecting the garbage bag during compression, and the garbage. It has a configuration that includes a device that encapsulates the compressed garbage bag and a discharge mechanism that discharges the encapsulated garbage to the transport pipe side.

[Example] Hereinafter, the present invention will be described in detail with reference to the drawings.

As shown in Fig. 2, an input port 3 for inputting garbage 2 is opened at a desired position in the middle of the cylindrical garbage storage and discharge device main body casing 1, and a 14 is attached to the input port 3 so as to be openable and closable. Furthermore, a lid locking device 5 and a close limit switch 6 are provided as safety devices in the input port 3, and an indicator light 7 that lights up when the close limit switch 6 is operated is provided near the input port 3.

An inner cylinder having a funnel-shaped guide part 8 at the top and an open bottom is used as a means to form a space for temporarily storing the garbage 2 input from the input port 3 and to protect the garbage bag 15 during garbage compression as described later. 9 is disposed within the main casing 1, and
A hoisting winch 10 is installed at the upper end of the main body casing 1, and the inner cylinder 9 is suspended and supported by a wire 11 fed out from the winch 10, and the inner cylinder 9 is lifted from the main body casing 1 by driving the winch 10. The winch 10 is configured to be able to move up and down between the upper and lower positions of the input port 3, that is, between the upper limit position shown by the imaginary line and the lower limit position shown by the solid line. It is provided with limit switches 12 and 13 for stopping the driving of the motor.

As shown in FIG. 3, a cylindrical case 1 is provided on the outside of the inner cylinder 9.
A garbage bag 15 stored inside the container 4 is placed over the container from below like a folded lantern, and the case 14 is suspended from the guide portion 8 of the inner tube 9 in a cartridge manner so that the case 14 can move up and down together with the inner tube 9. , Garbage bag replenishment opening 1 [! 16 is provided to match the upper limit position of the rise of the inner cylinder 9.

As a device for compacting the waste 2 thrown into the inner cylinder 9, there is a device located above the input port 3 in the main casing 1.
The compression cylinder 11 is installed downward through a frame 19, and when the piston 18 of the compression cylinder 17 is projected, the piston 18 can be inserted into the inner cylinder 9. In addition, a circular turntable 22 that can rotate in contact with a friction wheel 21 attached to a motor 20 is arranged at the lower limit position F of the inner cylinder 9 so as to support the bottom of the garbage bag 15. 22 is mounted via a bearing 25 on the upper part of a discharge valve 24 which is connected to a discharge valve driving device 23 such as an air cylinder and can be horizontally moved (opened and closed). A connecting chute 28 connected to the transport pipe 26 via a branch pipe 27 is arranged below the discharge valve 24 in the closed position.
A ring-shaped seal packing 29 is attached to the upper end of the discharge valve 24 to keep the transport pipe 26 airtight, and a seal packing 29 is attached to the outer side of the seal packing 29 for use when a large load is applied to the upper part of the discharge valve 24. In order to protect the seal packing 29, a discharge valve seat 30, which is formed slightly lower than the upper end surface of the seal packing 29, is provided in a protruding annular shape.

Furthermore, as shown in FIG. 4, a level switch through hole 31 is formed in the guide portion 8 of the inner cylinder 9 at an opposing position, and the hole 31 extends horizontally when the inner cylinder 9 is at the lower limit position. Optical level switches 32 and 32 are installed facing each other on the line.

As shown in FIG. 5, a part of the main body casing 1 located approximately midway between the upper limit position and the lower limit position of the inner cylinder 9 is shown at the upper end of a garbage bag 15 which is compressed and filled with garbage 2. and lashing the two lower ends of the bag that will become the next garbage bag 15 at the same time,
In addition, a lashing device @ 33 equipped with a mechanism for cutting between two lashed places is pivotally mounted on a bin 34 so as to be able to rotate horizontally. In order to achieve this, the drive unit N36 is connected via the link mechanism 35.

Incidentally, the storage state of the lashing device 33 (the position indicated by the solid line) and the position detection at the center position of the main body casing 1 are detected by the husband limit switches 37 and 38.

Next, the operation will be explained with reference to FIGS. 2 to 6.

First, as shown in FIGS. 2 and 4, the piston 18 of the garbage compression cylinder 17 is contracted and positioned at the upper limit, the garbage bag 15 is attached to the inner cylinder 9, and the level switch 32.
When the light passes through and the garbage 2 can be thrown in, open the bean paste 4 of the inlet 3 and throw the garbage 2 into the inner cylinder 9 located at the lower limit position in the main body cable rung 1 (No. Figure 6 (a)).

Garbage 2 is thrown into the inner cylinder 9 to which the garbage bag 15 is attached,
When the garbage 2 is thrown in until the level switches 32 and 32 are shielded from light, the ON signal of the mitt switch 6 and the level switch 32, which closes simultaneously with the closing of the lid 4 of the inlet 3.
The lid locking device 5 is activated by the light blocking signal, and the lid 4 is locked (to prevent danger). Subsequently, the piston 18 of the compression cylinder 17 protrudes and compresses the waste 2 in the internal station 9 until a predetermined pressure is reached between it and the turntable 22. After compression, the piston 18 is retracted by the timer, the level switches 32 and 32 are turned on again, and the lid locking device @5 is released (FIG. 6(B)).

The above operation is repeated an appropriate number of times, and the level switch 32.3
When the compressed garbage 2 accumulates to the 2nd position and becomes full, the level switch 32.32 should be set to the light shielding state? ), the inner cylinder 9 is pulled up by the drive of the winch 10 while the piston 18 remains protruding. Thus, when the inner tube 9 is pulled up, the garbage bag case 14 is also pulled up together with the inner tube 9. At this time, the garbage bag 15 is sequentially transferred to the case 14.
(Fig. 6(C)).

Next, the piston 18 contracts and completely completes the compression cylinder 17.
After being drawn in, the turntable 22 on which the garbage bag 15 is placed is rotated by the motor 20 via the friction wheel 21, thereby twisting the middle part of the garbage bag 15 (a position above the garbage 2). Make a constriction. By the way, is the rotation of the turntable 22 correct? It stops at - (Fig. 6 (0)).

Furthermore, in this state, the lashing device 33 rotates and engages the narrow part of the garbage bag 15 by driving the driving device 36, clips the upper and lower parts, and also clips the middle part with force and vines. After cutting, the lashing device 33 returns to its original position (FIG. 6(E)).

Next, the discharge valve 24 is opened by driving the discharge valve drive unit W123, and the encapsulated garbage bag 15 falls into the transport pipe 26 by gravity via the connection chute 28 and the branch pipe 27, and the discharge valve 24 is opened again. is closed (Fig. 6(E)). Incidentally, since the garbage bag 15 slides inside the transport pipe 26 at a speed of about 10 Ill/S, it is necessary to have a material, thickness, etc. strong enough to withstand this movement. Thereafter, the inner cylinder 9 descends to the state shown in FIG. 6(c).

In the above, the replenishment time of the garbage bag 15 can be clearly indicated by counting the number of times the discharge valve 24 is opened and, when a predetermined number of times is reached, turning on an indicator lamp or the like that indicates garbage replenishment.

It should be noted that the present invention is not limited to the above-mentioned embodiments, and includes, for example, the lashing device 33, the lashing device rotation drive device 36,
The dust compression cylinder 17, the discharge valve drive device 23, etc.
High-pressure air or pressure oil may be used as the drive source (Also, the rotation mechanism of the turntable 23 may be of a gear type or a direct drive type of motor, etc., as long as it does not depart from the gist of the present invention. Of course, various changes can be made.

[Effects of the Invention] This has been explained above. As such, according to the municipal waste storage and discharge device of the present invention, (1) The bagging and tying operations of garbage are automated, so it is highly convenient.
