BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is a device for crushing organic waste in a home kitchen, a kitchen for business use, etc. with a crusher, and pumping it out of the system to wash the inside of a transfer pipe, Further, the present invention relates to an organic waste crushing pressure-feeding device and a pressure-feeding method capable of automatically returning from a backflow state when a backflow occurs.

[0002]

2. Description of the Related Art An example of a conventional organic substance crushing and pressure feeding device is shown in FIG. Numeral 17 is a crusher, which sinks organic waste such as garbage 1
Receive from 8 and crush. Reference numeral 19 is a pumping device, which is a tank for pumping the crushed organic waste to the outside of the system. The crusher 17 and the tank of the pressure feeding device 19 are connected by a transfer pipe 20. A check valve 21 is provided in the middle of the transfer pipe 20. Two
A discharge pipe 2 is connected to the discharge side of the pressure feeding device 19. Reference numeral 23 is a water tap.

In the conventional organic waste crushing and pressure feeding device as described above, organic substances such as kitchen waste crushed by the crusher 17 flow into the transfer pipe 20 and the backflow prevention valve 21, flow into the pressure feeding device 19, and then are discharged. It is discharged from the pipe 22 to the outside of the system. However, solid substances that could not be transferred remain in the transfer pipes such as the check valve 21, the transfer pipe 20, and the discharge pipe 22 on the secondary side of the pressure feeding device 19, and are easily settled. Crusher 1
Flow rate 5 to 10 liters / min from the upper water tap 23
A small amount of tap water is continuously supplied, and it is transferred by the pressure feeding device 19.

If the backflow prevention valve 21 provided to prevent backflow does not operate for some reason, the water level in the tank of the pumping device 19 may drop to a position where the pump does not function due to backflow. Occur.

[0005]

However, as described above, with only the flow rate of 5 to 10 liters / min supplied from the water tap at the upper part of the crusher, the ability to discharge the organic substances remaining and settling in the transfer pipe is required. However, liquids and solids that could not be discharged remain in the transfer pipe, and more than half of them are occupied by solids. For this reason, the joint portion of the transfer pipe is liable to accumulate the residue, and the residue is fixed, so that there is a problem that resistance during normal transfer occurs or clogging occurs.

Further, if the backflow prevention device does not operate when the pumping device is stopped, the pump may not function normally due to the backflow. However, since there is no apparent change in this phenomenon, there is a problem in that the worker does not know the occurrence of the phenomenon and further throws in an organic substance to cause pumping failure. Moreover, in order to recover from this phenomenon, it is necessary to open the priming tap 24 provided on the tank lid 19a of the pumping device 19 and put in a necessary amount of water, which is an extra work for discharging organic waste. There was a problem that it caused trouble.

The present invention solves the above-mentioned problems, and it is possible to reliably discharge the organic waste remaining and settled in the transfer pipe, prevent the transfer pipe from being clogged, detect the reverse flow, and restore it. An object of the present invention is to provide a waste crushing pressure feeding device and a method thereof.

[0011]

In the first aspect of the invention, in the normal operation mode, the clean water and the organic waste are mixed and crushed, and then sent to the pressure feeding device through the transfer pipe and discharged to the outside of the system under pressure. Further, in the cleaning mode, the organic matter remaining in the transfer pipe and settling means that the clean water stored in the storage tank is pressure-fed by the pressure-feeding device, and the amount of organic water in the pipe, for example, 30
Since clean water of liter / min or more is pumped, the residual amount of solids can be reduced to less than half of the residual amount of the conventional method.

Further, in the second aspect of the present invention, a backflow occurs in the backflow detection mode, and the water level detector in the storage tank detects this, and it is automatically determined that the pump is not functioning normally and the device is abnormal. Can be detected and controlled. The third invention and the fourth invention respectively show the above-mentioned cleaning mode and the pressure feeding method at the time of detecting the backflow.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a sectional view of an organic waste crushing and pressure-feeding device for treating kitchen waste generated in a kitchen or a kitchen. Reference numeral 1 denotes a pressure feeding device, which is a stainless steel tank and has a submersible pump 2 incorporated therein. Reference numeral 3 denotes a stainless steel storage tank, which is connected to the pressure-feeding device 1 by a stainless steel transfer pipe 4 that emerges from the bottom of the storage tank 3 and rises in a torii shape. A cast ball type check valve 5 is provided in the middle of the transfer pipe 4 path, and this is connected to the transfer pipe 4 by a union screw 6. A diaphragm-type water level detector 7 is attached to the lid 3a of the storage tank 3, and a short pipe 8 made of vinyl chloride is connected to this and extends into the storage tank 3. Also, the tank lid 3
A crusher (disposer) 9 is attached above a, and a hopper type sink 10 is provided above it. The water supply pipe 11 is connected to the sink 10, and the water supply pipe 1
A solenoid valve 12 is connected in the middle of 1. The hopper type sink 10 is a stainless steel sink body 1 having four legs.
3 and is connected to the leg 13a of the device operation panel 1
4 is attached to the operation unit 14a such as an operation switch, an emergency stop button, a washing mode button, and an abnormal lamp.
Are placed. Reference numeral 15 is an external discharge pipe, and 16 is a torii piping portion. In addition, a control box is installed separately from the above-mentioned organic waste crushing and pressure feeding device, and a breaker, a relay, and a sequencer are built in this.

First, at the time of normal crushing and pressure feeding, the start is performed by turning on the operation switch of the operation unit 14a.
As a result, the solenoid valve 12 is opened, water supply is started from the water supply pipe 11, and the disposer 9 and the submersible pump 2 in the pressure feeding device 1 are started. When the organic waste is put into the hopper type sink 10, it mixes with the clean water supplied from the water supply pipe 11,
The water drops into the disposer 9, is crushed, and is passed through the transfer pipe 4 by the negative pressure generated by the submersible pump 2 to the torii pipe portion 16
The sewage containing the organic waste that has been forcibly sucked into the tank of the pressure feeding device 1 after passing over the tank is discharged from the external discharge pipe 15 as pressured water to the outside of the system.
The operation can be stopped by turning on the operation switch again, the solenoid valve is closed and the disposer is stopped, the submersible pump 2 continues to transfer air, and stops 3 minutes after the second operation switch is turned on.

Next, as the operation control of the cleaning mode, the start is performed by pressing the cleaning mode button of the operation unit 14a. After that, under the control of the sequencer in the control box, the solenoid valve 12 is opened to start water supply from the water supply pipe 11, and the air pressure in the short pipe 8 rises as the water level in the storage tank 3 rises. The upper limit of the water level is detected. At this time, since the upper limit of the water level is lower than that of the torii pipe section 16, water does not flow into the pressure feeding device 1 due to gravity. Simultaneously with the detection of the upper limit of the water level, the electromagnetic valve 12 is closed and the submersible pump 2 is automatically operated to forcibly discharge the clean water stored in the storage tank 3 at a flow rate of 30 liters / min or more. Will continue to transfer air after the discharge of clean water and stop after 3 minutes.

The operation control in the backflow detection mode is a mode that operates only when the apparatus is stopped, and this control is performed by the sequencer. When the backflow occurs, the wastewater in the tank of the pumping device 1 flows into the storage tank 3 and the water level in the storage tank 3 rises.
The starter 7 detects the same principle as in the cleaning mode, and at the same time, automatically operates the submersible pump 2 and stops it 3 minutes after the detection. In this way, the device is washed by driving the submersible pump.
It is cleaned and solids are removed, and the device automatically returns. Also,
If the backflow is detected again within 5 minutes from the first backflow, it is determined to be abnormal, and the abnormal lamp of the operation unit 14a is lit up to notify.

[0017]

Industrial Applicability According to the present invention, as described above, the organic waste remaining in the transfer pipe and settling is pumped by the clean water stored in the storage tank and the necessary amount of clean water to be discharged by the pumping device, and is automatically washed. Therefore, the residual amount of solid matter is less than half that of the conventional method, and it becomes difficult for the solid matter to adhere.
It is possible to prevent resistance during transfer and prevent clogging of piping. Further, even if the backflow prevention device does not function, it is possible to prevent overflow of sewage containing organic waste and generation of a foul odor without hindering work.
