Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drainage control device for a garbage disposal device used for equipment for crushing garbage such as kitchen garbage.

[0002]

2. Description of the Related Art Conventionally, in the case of treating kitchen waste such as kitchen garbage, the bottom plate of the sink is equipped with a kitchen treatment device having a function of crushing the kitchen waste by a fixed blade and a crushing tool provided on a rotating plate. It is configured to discharge the crushed kitchen waste together with sewage such as miscellaneous wastewater from the drain port provided in the kitchen waste processing device through the drainage pipe as it is.

[0003]

However, according to the above-mentioned conventional structure, the kitchen waste from the sink is crushed by the kitchen processing apparatus,
Since it is discharged as it is with the wastewater, in addition to wastewater containing crushed garbage, sewage just using detergent without garbage is also flowed into the wastewater treatment facility on the downstream side. It becomes complicated and hinders efficient treatment of wastewater.

The present invention has been made in order to solve the above problems, and provides a drainage control device for a kitchen waste treatment system, which simplifies the treatment conditions in a wastewater treatment facility and can efficiently perform wastewater treatment. It is intended to be provided.

[0005]

In order to achieve the above object, the drainage control device of the garbage treating apparatus according to the present invention is attached to the bottom plate of the sink and has a function of crushing the garbage thrown from the sink. A switching valve is provided on the drainage pipe of the treatment equipment, and high-load wastewater in the wastewater treatment equipment on the downstream side according to high-load wastewater containing crushed garbage and low-load wastewater not containing crushed garbage that is discharged from the waste treatment equipment. Each of the discharge paths to the treatment section and the low load wastewater treatment section is configured to be selected by the switching valve.

[0006]

With the above structure, the garbage thrown from the sink is crushed by the garbage treating device and drained together with the sewage. When the wastewater from the above waste treatment equipment is high load sewage containing crushing garbage by the switching valve on the drainage pipe, this sewage is sent to the high load sewage treatment section of the sewage treatment facility and does not include crushing waste In the case of low-load wastewater, this wastewater is sent to the low-load wastewater treatment section in the wastewater treatment facility and treated.

[0007] In this way, the sewage water is sent to the sewage treatment unit corresponding to each sewage by switching operation of the sewage depending on the high load or the low load, so that each sewage treatment unit does not need a complex function, A treatment suitable for wastewater can be performed, and proper treatment and speedup can be achieved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, a garbage processing device 2 is attached to the bottom plate of the sink 1. This garbage processing device 2
It has a function of crushing the garbage thrown from the throwing port 3 communicating with the sink 1 by, for example, a rotating crushing tool 4 and a cylindrical fixed blade 5 surrounding the crushing tool 4.

Reference numeral 6 denotes a sewage treatment facility for treating sewage discharged through the kitchen waste treatment device 2. The sewage treatment facility 6 has a high load sewage treatment unit 7 including crushed garbage and a low load that does not include crushed garbage. It is provided separately from the sewage treatment unit 8.

On the drainage pipe 9 of the garbage processing device 2,
A switching valve 10 such as a three-way valve is provided. This switching valve 10 is operated in accordance with high load sewage containing crushed garbage and low load sewage not containing crushed garbage from the garbage treatment device 2 to pass each sewage through pipes 11 and 12, respectively, to a high load sewage treatment unit. 7 and the low-load sewage treatment unit 8 respectively.

Next, the operation of the above configuration will be described. When the garbage in the sink 1 is thrown into the garbage treating device 2 through the charging port 3, this garbage is crushed by the crushing tool 4 and the fixed blade 5 in the above garbage treating device 2 and the drainage pipe is discharged together with the waste water such as waste water. It is drained to the downstream side via.

When high-load sewage containing crushed garbage is discharged from the garbage treatment device 2, the switching valve 10 selects one of the discharge paths, that is, the pipe 11 to remove the high-load sewage from the sewage treatment equipment. 6 is sent to the high-load wastewater treatment unit 7 and treated there. Further, when low-load sewage that does not contain crushed garbage is discharged from the garbage treatment device 2 as in the case of washing food or the like on the sink 1 with a detergent, the switching valve 10 is used to connect the other discharge pipe By selecting 12, the low load sewage is sent to the low load sewage treatment unit 8 in the sewage treatment facility 6 and treated there.

As described above, the switching valve 10 is used depending on whether the sewage discharged from the garbage treatment device 2 has a high load containing crushed garbage or a low load containing no crushed garbage.
Since the drainage path is switched by and sent to the dedicated wastewater treatment units 7 and 8, respectively, the treatment conditions of the entire wastewater treatment facility 6 are simplified, and high-load wastewater and low-load wastewater can be treated with high-level treatment functions. It can be processed efficiently. Further, since the crushed garbage does not flow into the low-load sewage treatment unit 8 that processes miscellaneous wastewater containing detergent and the like, there is no possibility of an increase in load on the load sewage treatment unit 8.

Although the switching valve 10 is manually switched, a sensor detects and discriminates between the high-load wastewater containing the crushing garbage and the low-load wastewater containing no crushing garbage. The switching valve 10 may be configured to be automatically switched.

[0015]

As described above, according to the present invention, sewage discharged through the garbage treatment device attached to the sink can be of high load containing crushed garbage or low load without crushed garbage. , By switching the discharge route by the switching valve provided on the drainage pipe and sending it to the high load sewage treatment unit and the low load sewage treatment unit respectively, the treatment conditions in the sewage treatment facility are simplified and the treatment efficiency is improved. In addition, it is possible to positively apply the preferable treatment method to the high load wastewater and the low load wastewater, respectively.
