DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a garbage disposal system for separating garbage into solids and liquids and burying liquids and solids.

[0002]

2. Description of the Related Art As a garbage disposal system for treating garbage generated in a kitchen or the like, there is, for example, a garbage disposal system disclosed in Japanese Utility Model Laid-Open No. 58-9639.

The garbage disposal system includes a disposer for crushing garbage, and a garbage (hereinafter, referred to as a crushed material) disposed downstream of the disposer for converting a crushed garbage into a solid component (hereinafter, referred to as a solid material) and a liquid component. (Hereinafter referred to as turbid water)
And a solid-liquid separation section that separates the solid and liquid.

[0004] The separated solid matter is stored in a bag and discarded, and the turbid water is drained to sewage or the like.

[0005]

However, in the above structure, the crushed material is placed on a skewer-shaped separation member and is moved by a transfer plate or the like to drop turbid water to perform solid-liquid separation. There has been a problem that the crushed material placed on the separation member has too much force to pass through the cradled separation member or to be clogged.

[0006] Further, since the solids subjected to solid-liquid separation are a collection of minute solids, it is necessary to perform a solid-liquid separation process for a long time in order to sufficiently perform solid-liquid separation.

Accordingly, an object of the present invention is to provide a garbage disposal system which prevents a situation in which a crushed material passes through a separation member and enables solid-liquid separation in a short time.

[0008]

In order to solve the above-mentioned problems, a first aspect of the present invention provides a disposer for pulverizing garbage into a pulverized material comprising a solid component and a liquid component, and a liquid of the pulverized product. Processing unit that stores, purifies, and drains waste, a solid processing unit that composts the solid content of the crushed material, and a solid-liquid separation unit that receives the crushed material from the disposer and separates it into solid and liquid. In a garbage disposal system, a solid-liquid separation unit receives a pulverized material and drops a liquid component of the pulverized material into the liquid processing unit to perform solid-liquid separation, and a pulverized material input from a disposer. Directly receiving the crushed material and causing the crushed material to lose its momentum, causing the crushed material to be received by a draining plate, and transferring a solid component separated on the draining plate to a solid processing section. And characterized in that:

That is, when the crushed material transferred from the disposer to the solid-liquid separation section is directly received by the draining plate in the shape of a pen, if the crushed material has a strong momentum, it passes through the draining plate or clogs. As the solid content increases, the crushed material from the disposer is once received by the transfer plate,
Thus, after the momentum of the crushed material is lost, the crushed material is received by a draining plate to perform solid-liquid separation.

The invention according to claim 2 is characterized in that the transfer plate performs a predetermined number of swinging operations of squeezing the crushed material received by the draining plate.

[0011] That is, the pulverized material is a collection of many fine solids,
Since the liquid component is attached during that time, sufficient solid-liquid separation cannot be performed simply by placing the liquid on a drainboard in the shape of a pen, and it takes a long time to sufficiently perform the solid-liquid separation. In view of this, the transfer plate is swung to squeeze the pulverized material placed on the draining plate, whereby solid-liquid separation can be performed quickly.

The draining plate 330 is composed of a plurality of draining plate pieces 331.
The draining plate piece 331 has a pen-shaped shape extending in the direction perpendicular to the rotation axis 311 of the transfer plate 310 and arranged at equal intervals in the direction of the rotation axis 311.

The spacing between the draining plate pieces 331 is such that the comb teeth 314 of the comb portion 313 can pass through. As a result, the solid matter sandwiched between the draining plate pieces 331 becomes
The teeth are scraped and removed by the comb teeth 314.

The liquid processing unit 40 includes a purification tank 41 for storing the turbid water separated by the solid-liquid separation unit 300, and an aeration device disposed below the purification tank 41 for aerating and purifying the turbid water by air from an air pump 45. The apparatus 42, a hollow membrane 43 that allows only purified water to pass through, a drain pump 44 connected to the hollow membrane 43 to feed purified water to the drain pipe 12, a water level sensor 46 that detects the water level of the purification tank 41, and the like. Have.

The hollow membrane 43 is provided with a number of holes having a predetermined diameter (for example, 0.4 μm) so that only purified water is absorbed through the holes.

The solid processing section 50 comprises a processing tank 51 for storing solids separated and transferred, a stirrer 52 for stirring the solids, an electric motor 53a, and a stirrer 52 for reducing the rotation speed of the electric motor 53a. Reducer 53b for rotating the motor, motor 53

Next, the operation of the garbage disposal based on the above configuration will be described. When performing garbage disposal, the switch 23 is turned on to activate the garbage disposal system. As a result, the electromagnetic valve 23 operates, and the garbage discarded from the sink 11 is crushed by the disposer 20 and transferred to the solid-liquid separation unit 300 by the transfer pipe 22.

Since the transfer pipe 22 is arranged to be inclined by a predetermined amount, it is possible to transfer the crushed garbage to the solid-liquid separation unit 300 without using any additional power or the like. .

When the garbage is not to be treated (for example, when flowing fresh water), the switch 23 is not turned on. In this case, the electromagnetic valve 23 does not operate, and the drainage or the like flows into the drainage pipe 12 as it is.

The crushed material transferred by the transfer pipe 22 is supplied to the solid-liquid separation unit 300. At this time, if the structure is such that the crushed material has a strong momentum and is directly received by the draining plate 330, it passes between the draining plate pieces 331 and passes through the liquid processing section 40.
The amount of solids falling on the surface increases and clogging occurs.

If the transfer plate 310 is not stopped at an appropriate position, the crushed material may spill into the liquid processing unit 40 or the solid processing unit 50, or turbid water may scatter to the solid processing unit 50.

In particular, when the transfer plate 310 is horizontal, the pulverized material from the transfer tube 22 is not received by the draining plate 330, and depending on the situation, the pulverized material may be directly injected into the solid processing unit 50. .

Therefore, in the present invention, when the switch 23 is dropped and the garbage disposal is started, the transfer plate 310 is made to stand by at a predetermined position, and the installation angle of the transfer pipe 22 is set to a predetermined angle. .

That is, as shown in FIG. 4, the transfer pipe 22 is provided at an angle of 30 degrees with respect to the horizontal, and the transfer plate 310 during standby is set at an angle of 95 degrees with respect to the horizontal. I have.

The stop position of the transfer plate 310 during the standby is determined by the magnet 31 provided on the side piece of the transfer plate 310.
5 is determined based on whether the first reed switch 335a is operated.

With this configuration, the pulverized material from the transfer pipe 22 once strikes the transfer plate 310, loses its momentum, and is received by the draining plate 330. Therefore, the pulverized material is not directly received by the draining plate 330 or directly injected into the solid processing unit 50.

Since the draining plate 330 is formed in the shape of a pen, the turbid water of the pulverized material is dropped from the draining plate 330 and stored in the purifying tank 41 of the liquid processing unit 40 provided thereunder. The solids are transferred to the solid processing unit 50 by the rotation of the transfer plate 310, and solid-liquid separation is performed.

It is also possible to quickly separate the solid and liquid of the pulverized material by swinging the transfer plate. FIG. 5 illustrates the swinging operation of the transfer plate 310.
FIG. 6 is a flowchart showing the control.

As shown in FIG. 5A, in the standby state, the swing frequency variable X has been initialized (step S1). Then, it is determined that the switch 23 is turned on (step S2),
When the switch 23 is turned on, the state is maintained for 10 minutes (step S3), and the swinging operation of the transfer plate 310 is started.

The swinging operation includes a reverse transfer operation in which the motor 302 is rotated in the reverse direction to rotate the transfer plate 310 clockwise in FIG. 5, and a forward transfer operation in which the motor 302 is rotated in the forward direction to rotate the transfer plate 310 counterclockwise. Performed by operation.

That is, as shown in FIG.
4, the reverse transfer operation is started, and the draining plate 330 and the transfer plate 31 are moved.
At 0, the crushed material is squeezed, and stops when the magnet 315 of the transfer plate 310 operates the first reed switch 355a (Steps S5 and S6).

Then, after stopping for a predetermined time (30 seconds), the turbid water adhering to the draining plate 310 or the like is sufficiently dropped (step S7), and then the normal transfer operation is started (step S7).
8), when the second reed switch 355b operates (step S9), the forward transfer operation stops (step S1).
0), the state is maintained for a predetermined time (30 seconds) (step S11).

Such a reverse transfer operation and a forward transfer operation are referred to as 1
As the rocking operation, the number of times of the rocking operation is determined in step S12.
, And the number of times is determined in step S13.

If the swing operation is performed five times or less, the process returns to step S4.
Proceeding to 14, the transfer of the solid to the solid processing unit 50 is started.

In step S14, the motor 302 rotates forward, whereby the transfer plate 310 starts to transfer the solid material as shown in FIG. 5C, and the solid material is transferred as shown in FIG. Is supplied to the solid processing unit 50.

Thereafter, when the first reed switch 355a operates, the transfer plate 310 stops (step S16) and returns to the standby state.

Since the crushed material on the draining plate 330 is squeezed by the swinging operation of the transfer plate 310, the solid-liquid separation can be performed quickly and efficiently.

During such a swinging operation, it is preferable to control so that a new pulverized material from the disposer 20 is not supplied to the solid-liquid separation unit 300, and furthermore, a message to that effect is displayed. Good.

The processing tank 51 of the solid processing section 50 has a carrier made of wood chips, such as sawdust, and activated carbon to which microorganisms that decompose solids, decompose the solids into carbon dioxide and water, and compost are attached. Is inserted.

The solid transferred by the transfer plate 310 and the carrier are mixed by the stirrer 52 and air is introduced into the inside.

Such a mixture of a solid and a carrier is
The heater is maintained at a predetermined temperature (30 to 40 degrees Celsius in the present embodiment) to promote the activation of microorganisms and the like.

The septic tank 41 of the liquid processing section 40 contains microorganisms (decomposing bacteria) that decompose and solidify minute solid matter, and the liquid stored in the septic tank 41 is supplied from the air pump 45 to the septic tank 41. By sending the air through the aeration device 42, the activity of microorganisms is enhanced to flocculate fine solids and further to scum.

The air pump 45 sucks air in the processing tank 51 from an air inlet 47 provided in the processing tank 51 and sends it to the aeration device 52.

This is because when the solid material is composted in the treatment tank 51, a bad smell is generated, and if the bad smell leaks to the outside, it gives a discomfort to the user and the like. 45 prevents intake and leakage to the outside.

Since the air is blown into the turbid water in the septic tank 41, the air is deodorized by the turbid water.

The septic tank 41 is provided with a water level sensor 46 for detecting a water level. When the water level sensor 46 operates, the drain pump 44 operates to drain water.

The water to be drained is water absorbed by the plurality of hollow membranes 43. That is, at the start of drainage, the septic tank 4
The turbid water stored in No. 1 has been purified, and flocs or scum is floating in the purified water.

Since the size of the hole provided in the hollow membrane 43 is smaller than the flock or scum, the water discharged through the hollow membrane 43 is purified water. With such a configuration, it is possible to reduce the turbidity of the wastewater to 300 mg / liter or less.

[0056]

According to the first aspect of the invention, the pulverized material from the disposer is once received by the transfer plate, and after having lost its momentum, is received by the draining plate. Even if the power of the crushed material is large, it is possible to reduce the amount of solids that pass through the crate-like draining plate or clog.

According to the second aspect of the present invention, the crushed material received by the draining plate is squeezed by the swinging operation of the transfer plate, so that the solid-liquid separation can be performed in a short time and efficiently. Will be able to do it.
