DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a garbage processing apparatus for processing garbage (garbage) generated in a kitchen and disposing a part of the garbage to a public sewer.

[0002]

2. Description of the Related Art Garbage (garbage) generated daily in kitchens such as general households and restaurants, if left unchecked, causes odors due to decay and causes propagation of pests and insects, thereby impairing the sanitary environment of the kitchen. . Therefore, in Europe and the United States, a kitchen crusher (disposer) is connected to the drain of the sink to crush the garbage that is directly injected into the drain by the operation of the disposer. Disposal is generally performed.

However, in Japan, there is a problem of clogging of sewage pipes by crushed garbage and an increase in load at a sewage treatment plant, and in a sewer combined with rainwater, overflow water containing crushed garbage is contained. Due to the inflow of natural waters such as rivers and lakes due to the inflow, eutrophication may occur. The permissible value of the quantity (BOD) is strictly regulated by the ordinance, and the wastewater from the disposer which contains crushed garbage and has a thick liquid state cannot satisfy the regulation, and the use of the disposer is prohibited. is there.

[0004] Under such circumstances, general garbage disposal in Japan involves collecting garbage with a net basket connected to a drain of a sink or a triangular corner basket placed at a corner of a sink sink. The garbage taken out of the garbage is disposed of together with other garbage.

[0005] However, in such kitchen waste disposal,
The kitchen garbage left in the mesh basket or the triangular corner basket rots and fills with a bad smell in the kitchen, the sewage contained in the kitchen spills out when the kitchen garbage is taken out, and the surroundings of the sink are contaminated. There are various inconveniences that hinder the maintenance of the sanitary environment in the garbage, and the garbage is frequently taken out, and each time the garbage is taken out, it becomes necessary to clean the mesh basket or the triangular corner basket and the surroundings of the sink, resulting in a large labor burden There was a drawback.

In order to solve these difficulties, the present applicant has
While continuously provided the disposer to the sink drain opening, 該De
The inside of the sink on the downstream side of the disposer and its surrounding wall
Cylindrical centrifugal separation of rotating the water passing hole and has axis around the diameter
A tank is arranged, wastewater from the disposer containing the crushed garbage is introduced into the centrifugal separation tank, and the solid content in the wastewater is strained on the peripheral wall of the centrifugal separation tank, and the moisture permeating through the peripheral wall is removed. We have already proposed a garbage disposal system that discharges only to the public sewer.

[0007] In this kitchen waste treatment apparatus, the wastewater to the public sewerage can satisfy the wastewater regulation according to the regulations, and the kitchen waste remaining in the centrifugal separation tank is dewatered after being crushed by the disposer. In addition, it is easy to take out and there is little possibility of decay, the labor burden required for kitchen waste disposal is reduced, and the sanitary environment of the kitchen can be favorably maintained.

[0008]

However, in the above garbage disposal apparatus, the wastewater introduced from the disposer into the centrifuge tank once falls on the bottom surface and is pressed against the peripheral wall by the centrifugal force accompanying the rotation of the centrifuge tank. Contained in the wastewater
Since up straining of Murrell solids has a configuration to be performed, easily solids taken strained is concentrated near the bottom surface, a peripheral wall
There is a disadvantage that efficient straining using the whole is not performed, the garbage can not be processed many times continuously, and frequent removal of the filtered solids is required.

[0009] Further, the strainer was strained into a centrifugal separation tank.Solid content
Is sufficiently dehydrated to prevent its decay
Must be performed at high speed to obtain the desired dehydration performance.
When a rotating centrifuge is used, the size increases with rotation.
Vibration may cause harsh noise.
You.

Furthermore, the solids in the waste water introduced during rotation of the centrifuge vessel is pressed against the peripheral wall close to the introducing position in a plan view, because taken strained at the position, adheres to the peripheral wall easily solids occur circumferential direction of the bias, there is difficulty rotational vibration of the centrifuge vessel is promoted by the occurrence of an eccentric load due to the bias, frequent the strained taken solids for eliminating this eccentric load There is an inconvenience that the removal of the garbage cannot be performed continuously because of the forced removal.

The present invention has been made in view of the above circumstances, and eliminates the concentration of solids in the vicinity of the bottom surface and the deviation in the circumferential direction in a centrifugal separation tank for filtering solids in drainage from a disposer. The object of the present invention is to provide a garbage processing apparatus which can obtain a predetermined dewatering performance without adopting a high rotation speed, does not need to frequently remove strained garbage, and can perform continuous processing many times.
