Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disposer system having transport means.

[0002]

2. Description of the Related Art Disposers are equipment for crushing garbage together with water and flowing the garbage through a sewer pipe. The disposer can be removed from a kitchen without spoiling the garbage, so that it is excellent in sanitation. This is a particularly effective garbage disposal technology in kitchens where food poisoning or infection is likely to occur using kitchen waste, such as hospital-related or school meals. In addition, since the wastewater discharged from the disposer is appropriately treated by a wastewater treatment device, it can be said that the wastewater treatment device or the environment-friendly device is used.

[0003] Since the disposer wastewater is a high-concentration slurry composed of pulverized garbage and water, it is difficult to discharge under natural flow like conventional kitchen wastewater and miscellaneous wastewater.
For this reason, a method of increasing the amount of water when the garbage is crushed by the disposer to a level at which the garbage can be transported, a method of once supplying the water to an underground drainage tank, and then transporting the same by a pump are considered.

[0004]

However, in the method of allowing the disposer wastewater to flow naturally, the water is transported using water as a medium, so that it is necessary to supply more water than is required for crushing by the disposer. . In addition, since the grease strap for removing oil and fat is not mechanically provided in the drainage passage of the disposer body, there is a problem that oil easily adheres to the piping system. Also,
Even when transported by a pump, it is necessary to make the slurry concentration such that it can be flowed by the pump, so that it is necessary to supply more water than is required for pulverization, and water has been wasted. Further, problems such as deterioration of solid-liquid separation characteristics in the disposer wastewater treatment apparatus due to a decrease in the slurry concentration, and an increase in the capacity of the wastewater treatment tank due to an increase in the amount of slurry have occurred.

Also, in the case of natural flow, a large amount of garbage such as bones and shells, which are supplied in large quantities, accumulates in the pipes, and the drainage does not flow to the disposer but flows backward from the sink. Had.

[0006] Further, the pump for transferring the solid content has a loud noise and is not durable.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional problems, and an object of the present invention is to provide a disposer system having means for reliably transporting the disposer drainage with a minimum amount of water.

[0008]

Means for Solving the Problems In order to solve the above problems, in the present invention, as a first gist, in the disposer system, the disposer drainage is carried out by a jet pump. A jet pump is a pump to which Bernoulli's theorem is applied, and is a pump to which a fluid around a high-speed fluid is applied by an action of being drawn by the high-speed fluid. This pump is actually used in aspirators, steam ejectors or venturi scrubbers. By sending the transport liquid to the jet pump at a high speed, it becomes possible to send a suspension containing crushed garbage such as a disposer. Disposer wastewater contains solids,
Since this solid content itself does not pass through the reduced diameter portion of the jet pump, it does not adversely affect the jet pump itself.

In addition, since the pump can be installed at a location remote from the disposer installation location, for example, outdoors,
There is no trouble such as noise, and the kitchen is not polluted by odor or sewage generated during maintenance.
In addition, since the liquid can be sent in a full flow state by the pump in the pipe, a shear stress acts on the entire pipe, and the deposition of oils and fats can be prevented.

[0010] A second gist is that a liquid obtained by treating wastewater generated in a facility where a pressurized disposer is installed is pressurized by a pump and supplied to a jet pump. This eliminates the need to use a water supply, thereby reducing disposer processing costs. In addition, since the concentration of the disposer wastewater is higher than in the past, it is expected that the separation efficiency of the solid-liquid separator in the disposer wastewater treatment system is improved, and the capacity of the wastewater treatment device can be reduced due to a decrease in the amount of the disposer wastewater. The liquid to be supplied to the jet pump does not need to contain solids and does not contain any component that adversely affects the wastewater treatment equipment. It is. Specifically, the liquid content after solids are separated from the disposer wastewater, the tap water, or the well water may be used, but from the viewpoint of securing the supply amount and increasing the water load of the wastewater treatment device, The liquid content after separating the solid content is most desirable. At this time, the separation of the solid content does not need to be precise, and may include a solid content that does not clog the nozzle of the jet pump.

A third point is that a hopper is provided between the jet pump and the disposer, and a drain space is provided between the disposer and the hopper. With this arrangement, even if the wastewater from the disposer is not drained or if it flows backward from the sewer pipe, it overflows from the hopper and is discharged directly to the drain, so that food and cooking utensils near the garbage inlet of the disposer can be used. Will not be stained.

In a fourth aspect, a remotely controllable valve is provided between the jet pump and the hopper. Optimal discharge of disposer drainage by sequentially controlling all electric and electronic devices related to the operation of the valve and the pump for supplying the jet pump drive liquid, as well as the disposer and the automatic water supply device for the disposer. It becomes possible. As an example, after the operation switch of the disposer is turned on, first, the pump for supplying the jet pump driving liquid is driven to secure suction force for discharging the disposer drainage. Thereafter, first, after the valve that can be remotely operated is opened, water supply to the disposer and operation of the disposer start, and garbage is crushed. The wastewater discharged from the disposer is discharged to a hopper and sent from the hopper to a disposer wastewater treatment device via a jet pump. The means for remote control may be electrical or pneumatic. In addition, considering the fact that the solid content is contained in the disposer drainage and that the disposer drainage pressure is low, valves with complicated flow paths such as ball valves are not appropriate, and butterfly valves and butterfly valves are not suitable. A highly sanitary valve such as a ball valve or a rotary valve is selected.

A fifth gist is that a plurality of disposer drains are supplied to one hopper. According to this configuration, the number of elements for discharging the disposer can be reduced, so that the cost can be reduced. In particular, in the jet pump method, since the solid content is contained in the disposer drainage, the pump, the jet pump, and the hopper cannot be configured in series in one piping path, and it is effective to share the hopper.

A sixth gist is that a water level sensor attached to a hopper controls a water supply valve, a disposer, a jet pump and a valve of the automatic disposer water supply device. In accordance with the discharge speed of the disposer wastewater supplied to the hopper, it is possible to increase the discharge capacity, reduce the amount of water supplied to the disposer, or stop all elements in an emergency.

FIG. 1 shows an embodiment of the present invention. An automatic water supply device 2 is installed in the disposer 1. The disposer 1 includes a continuous processing method in which garbage is continuously supplied and a batch processing method in which garbage is intermittently supplied. After the drainage of the disposer 1 is discharged from the disposer 1, the trap 3
Through the drain port space 15 and into the hopper 16. The hopper 16 is provided with an overflow port 6, and discharges the disposer wastewater to the sewage when the drainage path is abnormal. The drain space 15 is defined by the distance between the disposer drain pipe and the upper edge of the hopper 15 or the height between the disposer drain pipe and the overflow port connection port. This drain space 15 is, for example, HASS-206.
It is designed by the method specified in.

The disposer wastewater introduced into the hopper 16 reaches the jet pump 9 when the valve 8 provided below the hopper 16 is opened, and is discharged to the disposer wastewater treatment device 11 by the action of the jet pump 9. Is done.

The jet pump 9 can be driven by introducing a fluid into the jet pump 9 at a high flow rate by the circulation pump 10. In the case of this embodiment, the treatment water of the disposer wastewater solid-liquid separation device 12 provided in the disposer wastewater treatment device 11, that is, the liquid obtained by removing solids from the disposer wastewater is circulated by the circulation pump 10 to be driven.

The circulating pump 10 may be either a positive displacement pump or a speed pump. However, considering a high flow rate, a speed pump, for example, a submersible pump is desirable. When the drainage speed of the disposer drainage is higher than the suction force of the jet pump 9, the disposer drainage is accumulated in the hopper 16. When the amount of the disposer drainage accumulated in the hopper 16 becomes excessive, the water level sensor 7 mounted in the hopper 16 operates to stop the operation of the disposer 1 or reduce the amount of water supplied to the automatic water supply device 2. Can be turned off. At the stage when the water level of the hopper 16 has dropped due to this measure, the normal processing operation can be performed again.

In the disposer system of the present invention, since a large number of electric devices are installed, sequence control by the control device 5 is necessary. An example of this sequence control is shown below.

The operation of the disposer 1 is performed by the operation switch 4
Is started by First, the circulation pump 10 is driven when it is confirmed by the drainage water level sensor 14 for driving the jet pump 9 that the drainage amount is equal to or more than the specified amount.
The circulation pump 10 discharges a predetermined amount of water, and a suction force of the jet pump 9 is generated after a delay time. When the suction force of the jet pump 9 is generated, the valve 8 is opened, and the operations of the disposer 1 and the automatic water supply device 2 are started. The raw garbage can be put into the disposer 1 in a batch process such as putting the garbage into the garbage bucket at one time, or the user puts garbage on the trough in a self-service cafeteria and continuously drains the trough. Any of a continuous type disposer such as the one used in the disposer may be used.

The water discharged from the disposer 1 is discharged into the drain space 15.
Into the hopper 16 via the valve and reach the jet pump 9 via the valve 8, where
The liquid is sent to 1. When a plurality of disposers 1 are installed, it is possible to consolidate the transport paths by putting drainage from the plurality of disposers 1 into one hopper 16.
