Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for quickly and surely drying water-containing organic waste such as kitchen waste, which is made of leftovers, leftovers, etc., discharged from detached houses, condominiums, commercial kitchens and the like. The present invention relates to a waste treatment device that can be discarded.

[0002]

2. Description of the Related Art Conventionally, water-containing organic waste such as kitchen waste discharged from kitchens such as kitchens of general households cannot be discharged directly to public sewers together with kitchen drainage from the drain of a kitchen sink, for example. For example, a mesh basket is installed at the drainage port of a sink, and when a proper amount of water-containing organic waste is accumulated in the basket, the basket is drained and then packed in a vinyl bag or the like for disposal. However, this method not only causes complications such as packing in a plastic bag etc. each time the kitchen waste is discharged from the kitchen and discomfort due to a bad odor, but it also causes a bad odor due to the fact that it is stored until it is discarded. It was a major factor in promoting environmental deterioration and poor hygiene.

In view of the above-mentioned circumstances, it is possible to easily and hygienically dispose of kitchen waste generated in kitchens, etc. by crushing the kitchen waste finely by crushing means such as a disposer and discharging it together with sewage into a public sewer. It is conceivable that if the crushed kitchen waste is discharged directly into the public sewer together with the sewage, the crushed material may cause clogging of the sewer pipe, or due to insufficient treatment capacity at the final sewage treatment plant. The current situation is that the problem of polluting water quality has not occurred and it has not spread until today.

Therefore, in order to solve the above-mentioned problems, a composting device for directly fermenting water-containing organic waste such as kitchen waste for composting is well known today.

[0005]

However, in order to treat water-containing organic wastes that are generally used today, in a waste treatment device adopting a compost system, the crushing treatment is performed by using crushing means such as a disposer. Since the water-containing organic solid waste contains a large amount of water at this point,
The organic solid waste having a high water content is directly discarded in the composting device. As a result, in the composting device, since water becomes excessive and it becomes difficult to supply oxygen, the anaerobic fermentation is promoted, and the heat generated during fermentation serves as the heat of vaporization of water. Therefore, it has been difficult to raise the solid waste to a temperature required for a predetermined fermentation temperature.

For this reason, the treatment efficiency of the solid waste by aerobic fermentation is lowered, the composting treatment is delayed, or the solid waste treated by fermentation is discharged each time, and further, the fermentation treatment process. There are various problems such as the living environment of residents is deteriorated due to the odor generated in.

Further, in the waste treatment apparatus of the compost system, every time the water-containing organic waste is treated, various base materials necessary for the fermentation treatment such as aerobic fermentation bacteria must be prepared in advance. There is also a problem that the cost of waste treatment is unnecessarily high.

In order to solve the above problems, the present invention provides
Instead of composting kitchen waste with a composting device,
The solid waste obtained by separating the sewage from the water-containing organic waste is dried in a waste treatment tank, and the dried waste is directly discharged from the waste treatment tank using a screw for waste transport, It is an object of the present invention to provide an improved waste treatment device that enables the discharged waste to be temporarily stored in a storage tank and then disposed of in the same manner as ordinary flammable waste.

According to an eleventh aspect of the present invention, in the waste treatment apparatus according to the tenth aspect, the storage tank is configured to accommodate a storage box for storing the dried waste so that the storage box can be taken in and out. And

According to a twelfth aspect of the present invention, in the waste treatment apparatus according to the first aspect, the waste treatment tank is provided with a means for drying steam containing odors and for deodorizing the dried odors. And a deodorizing device configured by means.

The waste treatment apparatus of the present invention separates water-containing organic waste such as kitchen waste finely crushed by a crusher such as a disposer into solid waste and sewage, and the solid waste has an inverted conical bottom surface. Stir in a waste treatment tank formed into a shape at the required ambient temperature to completely remove water and dispose of it so that it can be disposed of. At the time of disposal, stir the waste from the waste discharge port of the waste treatment tank. Since it is configured to be automatically discharged by the blades and conveyed to a predetermined place by the screw for conveying waste to be temporarily stored, the solid waste separated from the sewage does not bother humans at all, and Since it is possible to dispose of odors as waste that can be discarded without being emitted to the outside, as a result, the disposal of kitchen waste generated in the kitchen etc. can be automatically performed without human labor, and
It is convenient because it can be processed hygienically.

Moreover, a screw for conveying waste is provided in parallel with the waste treatment tank, and the dried waste is discharged from the waste treatment tank to the portion of this screw by the rotation of the stirring blade to convey the waste. Since it was configured to automatically convey to a predetermined storage location with a screw for temporary storage
When discharging and transporting the waste, the waste itself is not exposed to the outside at all, so the waste does not leak to the outside or dissipate odors during transport, and it is hygienic and Another advantage is that it can be automatically transported and stored.

Since the waste treatment apparatus of the present invention is configured to perform stirring and drying treatment while maintaining the ambient temperature in the waste treatment tank at a predetermined temperature, the solid waste can be dried quickly. It can be done reliably. Further, in the drying treatment, the waste treatment tank is provided with a deodorizing device equipped with a means for heating and drying water vapor containing odor and a means for deodorizing the dried air. The drying process can be performed more efficiently and smoothly and without causing discomfort due to the odor generated during the process.

In the waste treatment device of the present invention, when the dried waste is conveyed by the screw for conveying waste,
Since the screw is configured such that a part of its blade member faces the inside from the waste discharge port of the waste treatment tank,
At the time of discharging the waste, the screw for transporting the waste partly enters the waste discharge port, so that the waste stirred by the stirring blade is directly received from the waste treatment tank. Since it can be discharged and transported to the storage location,
The waste can be discharged and transported quickly and smoothly.

At this time, the waste discharge port formed in the waste treatment tank is always open, and the stirring blade rotates to stir the solid waste for most of the time required for the drying process. Due to the drying process, a part of the solid waste is discharged up to the screw transporting screw part, but the screw is installed adjacent to the waste treatment tank without being exposed to the outside. Therefore, the waste discharged from the waste discharge port to the waste transport screw is left at the discharge position unless the screw is driven. Although not carried out, the drying treatment can be satisfactorily performed depending on the ambient temperature in the waste treatment tank.

In the waste treatment apparatus of the present invention, a plurality of rod-shaped projections are provided around each blade member of the screw for conveying waste, or a plurality of recesses and protrusions are directly formed on the peripheral edge of the blade member. Therefore, at the time of discharging the waste, if the waste discharge port is blocked by the waste from which water has been removed during the drying process of the solid waste, by driving the screw for conveying the waste, Since the wall of the waste material blocking the outlet can be easily destroyed by the rod-shaped projections or the concaves and convexes formed on the blade member, the waste material discharge port was blocked when discharging the waste material. However, since it is possible to break this and discharge the waste, there is no difficulty in discharging the waste itself due to the wall of the waste, and the discharge of the waste can be automatically performed without human labor. ,
Moreover, it can be performed quickly and reliably.

In the waste treatment apparatus of the present invention, the waste discharge port for discharging the dried waste is opened at a position where a part of the dried waste can remain in the waste treatment tank. Therefore, when a new solid waste is dried, it can be mixed and agitated with the remaining waste that has already been dried, so it is attached to the solid waste. In addition to being able to absorb moisture well, the drying process of newly added solid waste can be performed quickly by using the remaining waste as a base material without replenishing the base material. It is possible to perform the drying process accurately. Moreover, since the waste discharge port of the waste is opened in the middle of the tapered portion near the bottom of the waste treatment tank, some of the waste is voluntary without using special means, and There is also an excellent advantage that it can be surely left on the bottom surface of the waste treatment tank.

In the waste treatment apparatus of the present invention, the waste conveyed by the screw for conveying the waste is stored separately (connected) to the waste treatment tank near the end of the screw for conveying the waste. Since it is configured so that it can be temporarily stored and stored without being exposed to the outside of the tank, the dried waste can be reliably transferred to and discharged from the storage tank by the screw for transferring waste. Moreover, by storing the bag member in the storage box for storing the waste in the storage tank in advance, it becomes possible to directly store the waste in the bag member. Compared to the case where the waste is taken out from the storage tank, the waste can be taken out from the storage tank in a state where the waste is accommodated in the bag member quickly and reliably without being hindered by bad odors, etc.
Since the work of disposing of waste can be troubled by bad odors and the trouble of packing the waste in the bag member,
Disposal of waste can be performed hygienically and quickly and easily.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the present invention will be described below with reference to FIGS. Waste treatment device A of the present invention
Is roughly divided into water-containing organic waste (hereinafter referred to as kitchen waste) generated in the kitchen etc. into solid waste and sewage,
A waste treatment tank 1 for drying the solid waste separated from the wastewater to treat it as a waste, and a screw for conveying the dry waste (hereinafter referred to as a screw). 2 and a storage tank 3 for temporarily storing the waste conveyed by the screw 2.

Next, the detailed structure of the waste treatment apparatus A will be described. First, in the waste treatment tank 1, as shown in FIG. 1, the central portion of the bottom surface is formed into a flat shape, and the flat surface a has a taper portion which has an inverted conical shape upward from the periphery thereof. Body part 4 formed integrally with the taper part 4 and extending in a vertical direction from the upper edge of the taper part 4 in the vertical direction thereof.
The tank main body 6 is configured by including.

The tank body 6 is provided with an electric heater 7 for maintaining the ambient temperature of the tank body 6 at a required set temperature (waste drying temperature) in the taper portion 4, and the electric heater is also provided. A heat insulating material 8 is attached to the outside of the tapered portion 4 and the body portion 5 in a state where the heat insulating material 8 is surrounded. In the present embodiment, instead of the electric heater 7, for example, hot air having a required temperature is blown into the tank body 6 so that the tank body 6 is heated.
The ambient temperature inside may be maintained at a predetermined set temperature.

In the tank body 6, as shown in FIG. 1, a drive for penetrating the flat surface a of the tank body 6 in a watertight manner by the base end of the stirring blade 9 which rotates along the tapered portion 4. A stirring blade 9 attached to the shaft 9a by being attached thereto is rotatably attached. The drive shaft 9a of the stirring blade 9 is a tank body 6
Is drivably connected to the electric motor 10 which is vertically provided under the flat portion a. The tank body 6 is provided with a stirring blade 9 and an electric heater 7 and is attached to a support member 11 including a support frame body of the waste treatment apparatus A in a state of being lifted to a certain height from the ground surface. Has been.

In FIG. 1, reference numeral 12 denotes an opening / closing lid which covers the upper opening of the tank main body 6 so as to be openable / closable. The opening / closing lid 12 includes, for example, a crushing means 13 such as a disposer for crushing garbage.
And a solid waste inflow tube 15 formed so as to be able to communicate with the solid-liquid separating means 14 for separating the crushed kitchen waste into solid waste and water (sewage), and a deodorizing process for removing a bad odor generated in the tank body 6. The deodorizing device 16 is installed in communication with the inside of the tank body 6.

Outside air is introduced into the tank body 6 through the inflow cylinder 15 described above.
An outside air introducing hole 15a formed by a structure (for example, a member that functions as a check valve) that allows the air to flow into the tank body but does not discharge the air inside the tank body 6 is opened. Further, the deodorizing device 16 is roughly configured by a blower (not shown) that discharges water vapor containing odor, a heater (not shown) that dries odor containing water vapor, and a deodorizing member (not shown) that deodorizes odor from the dried air. .

As described above, the waste treatment tank 1 has the tank body 6
Is equipped with the aforesaid electric heater 7 for constantly maintaining the stirring blade 9 and the ambient temperature in the tank body 6 at a predetermined temperature by a temperature sensor (not shown). An inflow cylinder 15 and a deodorizing device 16 are provided respectively.

Next, the screw 2 for conveying the above-mentioned waste will be described. The screw 2 is shown in FIGS.
As shown in FIG. 5, in the taper portion 4 of the waste treatment tank 1, in a cylindrical transfer cylinder 17 whose both ends are closed in a state where the taper portion 4 is orthogonal to the taper portion 4 and is horizontally laid,
It is rotatably inserted in close proximity to the wall surface of the transfer cylinder 17 (for example, at an interval of about 1 to 3 mm). One end of the transfer cylinder 17 is fixed to the taper portion 4 of the tank body 6, and the other end is mounted and fixed on the upper end of the discharge cylinder 17a communicating with the inside of the storage tank 3 so as not to fall off. The transfer cylinder 17 is not only horizontally extended so as to be orthogonal to the taper portion 4 of the waste treatment tank 1 but is also slanted slightly downward along the taper portion 4, for example. It may be attached in any form as long as it does not impair the transport function.

The screw 2 is supported at its one end by a bearing (not shown) provided at the end (right side in FIG. 4) in the transfer cylinder 17, and at the other end as shown in FIG. Is connected to an electric motor 20 mounted via a mounting member 18 so as to be drivable. 4 to 7 are provided at corresponding positions of the transport cylinder 17 and the tapered portion 4 of the tank body 6.
As shown in FIG. 5, openings are formed to connect the members 17 and 6 to each other.

That is, on the outside of the tapered portion 4 of the tank body 6,
As shown in FIGS. 4 to 7, the waste discharge port 21 is opened at a substantially middle position of the tapered portion 4. On the other hand, in the transfer cylinder 17 corresponding to the waste discharge port 21,
As shown in FIG. 5, a horizontally long elliptical inflow hole 22 is bored. The peripheral edges of the waste discharge port 21 and the inflow hole 22 are formed in the transport cylinder 17 so that the dried waste and odor discharged from the waste discharge port 21 do not leak to the outside of the transport cylinder 17. By welding the periphery of the inflow hole 22 to the tapered portion 4 of the tank body 6 by welding or the like so as to cover the waste discharge port 21, the inside of the transfer cylinder 17 and the tank body 6 are prevented from communicating with the outside. The carrier cylinder 17 is attached to the tank body 6.

In the screw 2 rotatably housed in the transfer cylinder 17, the blade member 2a located near the horizontally long inflow hole 22 formed in the transfer cylinder 17 flows in as shown in FIGS. It is attached so as to face the inside of the waste discharge port 21 through the hole 22, that is, the state in which the waste discharge port 21 is invaded. Further, the waste discharge port 21 has been described as an example provided at a substantially middle position of the taper portion 4 of the tank body 6, but the waste discharge port 21 is a part of waste processed at the bottom of the tank body 6. If it is opened at a position where it can remain,
It is not particularly necessary to limit the opening position.

This is because the waste discharge port 21 is opened in the taper portion 4 of the tank body 6 and the peripheral edge of the taper portion 4 is formed in an inverted conical shape, so that the screw 2 is, for example, the taper portion 4. Even if the blade members 2a are arranged in a straight line so as to be orthogonal to each other, the blade members 2a can enter the tank body 6 without any contact with the wall surface of the tapered portion 4. Therefore, even if the waste stays in the vicinity of the waste discharge port 21 in the form of a wall or a lump, the blade member 2a of the screw 2 enters the waste discharge port 21 and the wall surface of the waste, etc. Since it can be broken through and broken, the waste discharge port 21 can be easily opened, and the waste can be satisfactorily discharged from the inflow hole 22 into the transport cylinder 17.

Next, the discharge cylinder 17a is provided below the screw 2.
Storage tank 3 installed separately from waste treatment tank 1 via
As shown in FIG. 1, a predetermined amount of waste (for example, 1
750 g of garbage per day is treated in the waste treatment tank 1, and a storage box 24 having a size capable of accommodating the treated waste for 30 days) is accommodated so that it can be put in and taken out at all times. As shown in FIG. 9, for example, a resin bag member 25 for receiving the waste flowing down from the discharge cylinder 17a is attached to the storage box 24 in an open state, and the waste member is taken out when carrying out the waste. This makes it possible to easily take out the storage tank 3 without soiling the hands.

Next, the operation of the waste treatment apparatus A of the present invention will be described with reference to the timing chart diagram shown in FIG. The kitchen waste discharged in the kitchen such as a general household or a kitchen is finely crushed by the crushing means 13 such as a disposer, and is sent to the solid-liquid separation means 14 together with the drainage used in the kitchen through the pipeline. In the solid-liquid separation means 14, the kitchen waste sent together with the wastewater is separated from the wastewater, and the separated wastewater (sewage) is discharged to a wastewater treatment tank (not shown) through a pipe (not shown) for cleanliness. Treated and discharged into sewer.

The solid-liquid separating means 14 separates the solid waste remaining after the kitchen waste is separated into the kitchen waste and the waste water when a predetermined amount (eg, an amount to be treated per day) of the kitchen waste is introduced. It is transferred by a carry-out means (not shown) (for example, a screw conveyor) and discharged into the tank body 6 through the inflow cylinder 15 of the waste treatment tank 1. In the tank body 6, a base material 30 (see FIG. 8) such as sawdust, which is excellent in water absorption, is previously stored in a fixed amount on the bottom surface of the tapered portion 4.

When the solid waste is sent from the solid-liquid separation means 14 to the tank body 6, if the solid-liquid separation means 14 has kitchen waste to be processed next time, the kitchen waste is sent to the solid-liquid separation means 14. After the sent-out wastewater is separated and drained, the solid waste is not transferred to the waste treatment tank 1 according to a command from a controller (not shown), and stays in the solid-liquid separation means 14 until the next treatment as it is. It is stored (standby).

On the other hand, when the solid waste is discharged to the tank body 6, the electric motor 1 is instructed by a command from a controller (not shown).
0, the electric heater 7, and the deodorizing device 16 start driving (see 9, 7, and 16 in FIG. 10). When the electric motor 10 is started, the stirring blade 9 is rotated to stir the solid waste in the tank body 6.

Simultaneously with the rotation of the stirring blade 9, the electric heater 7 is also energized to maintain the ambient temperature in the tank body 6 at a required set temperature, that is, a temperature suitable for the drying treatment of solid waste. Further, the deodorizing device 16 is also started at the same time, and the outside air is introduced from the introduction hole 15a of the inflow tube 15 and is sucked together with the moisture and the odor in the tank body 6 to dry and deodorize the air containing the moisture and the odor. By discharging to the outside, the inside of the tank body 6 is constantly ventilated, and the drying process of solid waste is promoted.

As shown in the timing chart of FIG. 10, the stirring blade 9 is rotated forward / backward by the electric motor 10 at regular intervals (for example, every 10 seconds) in response to a command from a controller (not shown). By repeating the rotation stop time (for example, 30 seconds) and repeating the solid waste, the solid waste can be smoothly and favorably stirred without forming a lump.
Further, when the solid waste is stirred, the tank body 6 is always maintained at a preset temperature by the electric heater 7, and therefore, due to the synergistic effect with the stirring action of the stirring blade 9,
The solid waste can be dried quickly and easily.

During the stirring process, a part of the solid waste is discharged from the waste discharge port 21 opened at a predetermined position of the taper portion 4 into the transfer cylinder 17 that houses the screw 2 through the inflow hole 22. It In this case, that is, while the solid waste is being dried in the tank body 6 while being agitated, the screw 2 is not operating, and therefore the inflow hole 2
Part of the solid waste stays near 2 and the waste discharge port 2
1 may be temporarily blocked.

Since the transfer cylinder 17 communicates with the inside of the tank body 6 through the inflow hole 22 and the waste discharge port 21, a part of the solid waste is discharged and accumulated in the transfer cylinder 17. Even in this case, by effectively utilizing the residual heat from the inside of the tank body 6, the solid waste in the tank body 6 can be dried without much difference from the case of drying. It should be noted that steam (humidity) containing an odor generated when the solid waste is being dried while being stirred in the tank body 6 is processed into dry air by deodorizing the odor by the deodorizing device 16. Since it can be discharged to the outside, the bad odor is never emitted to the outside by the drying process, and the solid waste can be smoothly dried.

As described above, when the solid waste is dried in the tank body 6 for the set time (in this example, 8 hours as shown in FIG. 10), the electric motor 20 is instructed by the controller (not shown). Is started and the screw 2 is driven (see 2 in FIG. 10). The waste accumulated in the transport cylinder 17 by driving the screw 2 is transported to the discharge cylinder 17a side by the rotation of the screw 2 as shown in FIG.
7a, it falls, and as shown in FIG. 9, it falls in the resin-made bag member 25 laid in the storage box 24 accommodated in the storage tank 3, and is temporarily stored.

On the other hand, when the waste material dried in the tank body 6 is discharged to the bag member 25 by the screw 2 and accumulated in the vicinity of the inflow hole 22, the stirring blade 9 immediately rotates the tank. From the waste discharge port 21 opening to the tapered portion 4 of the main body 6 through the inflow hole 22, the transfer cylinder 17
It is then discharged into the bag member 25 in the storage tank 3 from the discharge cylinder 17a.

The dried waste is used as a waste discharge port 2
When the waste discharge port 21 itself is blocked by the wall of the waste when discharging from 1, the part of the blade member 2a of the screw 2 is partially inserted into the inflow hole 22 as shown in FIGS.
Since it is configured to enter into the waste discharge port 21 from the above, when the screw 2 rotates, the blade member 2a close to the vicinity of the inflow hole 22 has the blade member 2a shown in FIGS. , The left and right sides of the inflow hole 22 are moved to the left and the right, or the wall of the waste material blocking the waste discharge port 21 is scratched and collapsed so that the waste discharge port 21 and the inflow hole 22 are separated from each other. Open to communicate with
The waste remaining in the tank body 6 is sequentially discharged from the waste discharge port 21 to the inflow hole 22 side of the transfer cylinder 17 by the stirring blade 9, and is transferred to the storage tank 3 by the screw 2, as shown in FIG. The bag member 25 accommodates the waste 27.

As described above, when the waste transportation is completed, the electric motors 10 and 20 and the deodorizing device 16 are stopped and the electric heater 7 is de-energized in response to a command from the controller. After the drying process of the predetermined amount of solid waste in the waste treatment tank 1 is completed, the solid waste prepared in the solid-liquid separation means 14 is continuously moved to the solid-liquid separation means 14 by a command from the control device. It is driven and transferred to the waste treatment tank 1, and the drying process is performed according to the above procedure.

The drying process of the solid waste is performed as described above.
After finishing once, the next work may be performed on the next day instead of continuously, and the kitchen waste is crushed by the crushing means 13.
After draining as it is without crushing with
The opening / closing lid 12 of the tank body 6 may be opened, and the solid waste may be directly put into the tank body 6 to perform the drying process. Further, the waste 27 which has been dried and stored in the bag member 25 is disposed of hygienically without opening the door of the storage tank 3 and taking out the bag member 25 from the storage box 24 without causing a bad odor or soiling the hands. can do.

When the discharge of the dried waste is completed, the tank body 6 remains at the lower portion of the tapered portion 4 of the tank body 6 without being discharged from the waste discharge port 21, as shown in FIG. There is waste. Since this waste exists below the position of the waste discharge port 21, it remains without being discharged from the waste discharge port 21, and this waste has been dried. Since there is almost no water, as a result, it can be used as the base material 30 in the next drying treatment of the solid waste.

That is, according to the present invention, the solid waste is dried by leaving a part of the waste treated as the base material 30 without discharging all the dried waste from the tank body 6. Since it is not necessary to prepare and replenish a new base material 30 each time each treatment is carried out, the solid waste treatment is almost maintenance-free and remains without preparing a new base material 30. By utilizing the waste that is used as the base material 30 as it is, it becomes possible to absorb the water similarly to the novel base material 30, so that the solid waste can be treated quickly, reliably, and economically. it can.

In the present invention, a part of the blade member 2a of the screw 2 is made to face the inside of the waste discharge port 21 of the tank main body 6 from the inflow hole 22 of the conveying cylinder 17, and the waste discharge function and the waste Although the wall of No. 1 was crushed, the present invention is not limited to this, and for example, as shown in FIG. 11, in a portion corresponding to the blade member 2a of the screw 2 on the stirring blade 9,
By notching the concave groove 9b and engaging the blade member 2a with the concave groove 9b, when the waste after the drying process is discharged from the waste discharge port 21 by the stirring blade 9, the screw 2 receives the waste. Not only doing well,
Even if the wall formed by the waste formed in the vicinity of the waste discharge port 21 is promptly destroyed, and as a result, the discharge / transport work of the waste is further swiftly and surely performed, the present invention can be realized. Is.

Further, as shown in FIG. 12, the screw 2 is provided with a plurality of rod-shaped projections 28 around the blade member 2a, or as shown in FIG. When the waste is discharged and conveyed, the wall of the waste formed in the inflow hole 22 and the waste discharge port 21 by the protrusion 28 and the crusher 29 is damaged or the waste is conveyed. It goes without saying that the waste may be conveyed while being unwound in the conveying cylinder 17. In addition, the present invention relates to the electric motor 1 in which the stirring blade 9 is attached to the lower portion of the tank body 6.

As described above, according to the present invention, after separating water-containing organic waste such as kitchen waste into solid waste and sewage,
Furthermore, the solid waste is treated as a disposable waste by drying the solid waste while stirring to remove water.
Since this waste is automatically discharged to a predetermined storage tank, temporarily stored, and then disposed of at a later date, the solid waste separated from the wastewater causes trouble to humans and dissipates odor to the outside. As a result, it is possible to quickly dispose of it as disposable waste, and as a result, the waste disposal work such as kitchen waste generated in the kitchen, etc. is automatically and hygienically performed without requiring human intervention. Can be convenient.

Further, according to the present invention, a screw for transporting waste, which transports waste treated to be discarded to a storage tank,
Since the waste treatment tank is configured to be installed side by side without being exposed to the outside, the waste itself is not exposed to the outside when it is discharged and transported, so the waste is being transported. It can be transported hygienically and automatically without being leaked to the outside or emitting a foul odor, and can be stored or discarded.

The waste treatment apparatus of the present invention is a deodorizing unit that dries the solid waste while maintaining it at a set temperature, and has a means for drying the steam containing odor and a deodorizing unit for deodorizing the dried air. Since it is configured with a device attached, the solid waste can be disposed of promptly and reliably, and the malodor generated during the treatment can be satisfactorily deodorized. Without
Solid waste can be treated.

In the waste treatment apparatus of the present invention, the screw for conveying the dried waste is constructed such that a part of its blade member faces the inside of the waste discharge port of the waste treatment tank. When discharging the waste, the screw
Since a part of it has entered the waste discharge port, the waste mixed by the stirring blade can be directly received, discharged from the waste treatment tank, and transported to a predetermined location. -Transportation work can be performed quickly and easily.

In the waste treatment apparatus of the present invention, since the waste discharge port for discharging the dried waste is opened at a position where a part of the dried waste can be left, The solid waste to be treated can be treated by mixing and stirring a part of the waste after the treatment as a base material, so that the water adhering to the solid waste can be absorbed well. As a result, the solid waste can be dried quickly and appropriately by leaving a part of the waste that has been processed to be discarded as the base material. Moreover, since the waste discharge port is opened in the middle of the tapered portion of the waste treatment tank, a part of the waste can be surely left as the base material, so that no new base material is required. There is also an advantage.

The waste treatment apparatus of the present invention does not expose the waste conveyed by the screw for conveyance to the outside in the storage tank separately installed from the waste treatment tank at the discharge end of the screw for conveyance. Since it is configured so that it can be temporarily stored, the dried waste can be easily stored and stored by preparing a bag member for storing the waste in the storage tank. Even when taking out waste, compared to when taking out from the waste treatment tank, it is possible to completely eliminate the trouble of having a bad odor, and the trouble of packing the waste in the bag member. And it can be done quickly and easily.
