Next, an operation method of the self-draining type surplus garbage disposal apparatus of this embodiment will be described.

In the first step, the computer is started. After the self-discharging type food waste treatment device is installed, the power supply is switched on, and the power supply indicator lamp is on; the water supply valve is opened, and the water pressure is displayed by the water pressure gauge 69; opening the oil removal box cover to check whether the oil removal box is full of liquid level; under the condition that the sewage disposal button is lighted, the starting button is pressed, the water supply electromagnetic valve 62 is opened in a linkage manner, the water outlet is automatically flushed, the conveying motor and the crushing motor 73 run, and the conveying belt 11 runs towards the crushing hopper 71. If the conveyer belt 11 runs in the reverse direction, which indicates that the phase sequence has a problem, any two phases in the three-phase power supply should be exchanged after the machine is stopped.

And the second step, operating. After the machine is started for about 1 minute, the garbage after meal to be treated is gradually thrown onto the conveyer belt 11 (note that the garbage after meal containing more soup is slowly poured onto the conveyer belt 11, too much soup cannot be poured in one time, the garbage after meal cannot be piled too high, the garbage is prevented from being stuck at the baffle of the protective cover and cannot be automatically thrown into the crushing hopper 71), the garbage is automatically conveyed and falls into the crushing hopper 71, the crushing cutter head 72 crushes the garbage, and the garbage flows into the dirt storage tank 2 along with water.

If the condition of the crushing bucket 71 needs to be checked in the treatment process, a stop button can be pressed, and the protective cover is opened to check after the machine is stopped. Or the protective cover can be slowly lifted in operation, and after the protective cover is opened for a certain angle, the magnetic induction switch 64 actuating equipment is stopped (if the protective cover is not stopped when being opened, whether the magnetic induction switch 64 is normal or not should be checked). After the checking is finished, the protective cover is closed, the starting button is pressed, and the equipment continues to operate.

The automatic discharging type food waste treatment device discharges water and runs electrically, the equipment monitors the sewage system, and the sewage button lamp flashes off along with the change of the condition of the sewage system. When the pollution discharge is normal, the pollution discharge button lamp is on, and the equipment is in a quasi-pollution discharge working state. After the liquid level in the sewage storage tank 2 reaches a first set liquid level, an electric signal is given, the sewage pump 3 is started to drain water, and the sewage pump 3 is automatically closed after the water drainage is finished. When the pollution discharge is out of order, such as the pollution discharge pump 3 is out of order or the pollution discharge pipe is blocked, the pollution discharge button lamp is turned off, and the water discharge action cannot be carried out. Under the condition that the sewage disposal button lamp is on, the sewage disposal button is manually pressed so that the sewage disposal pump 3 is turned on to drain water.

The self-discharging type food waste treatment device is provided with a high liquid level protection of the sewage storage tank. When the equipment is in operation and the pollution discharge is out of order, the pollution discharge button lamp is turned off, and when the continuous water inflow of the pollution storage tank 2 exceeds the first set liquid level, the equipment is automatically protected to stop and stop water, so that the water is prevented from overflowing. When the sewage discharge is recovered to normal, the equipment automatically drains water and recovers to normal operation.

After the food waste is treated and the sewage storage tank 2 is emptied, the protective cover can be opened, and the equipment stops running. The conveying belt 11 and the crushing bucket 71 are cleaned by the water gun 65, then the protective cover is closed, the stop button is pressed down to stop the machine, the sewage storage tank 2 is emptied by pressing the sewage discharge button again, and the residual garbage in the sewage storage tank 2 is prevented from generating peculiar smell. Under the normal and equipment circular telegram state of system negative pressure, all be automatic drainage when the liquid level reachs first settlement liquid level in the dirty jar 2, just start the drainage of dirty jar 2 through manual blowdown button of pressing after only shutting down. Note that: the blowdown button lamp goes out when the blowdown trouble, if manual washing, the overflow can appear in squirt 65 continuous water inlet dirt storage tank 2.

The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
