[0035] The domestic waste control oil pump 21 is controlled by the AC contactor KM1 and protected by the thermal overload relay FR1; the domestic waste crusher 23 is controlled by the AC contactors KM2 and KM3 and protected by the thermal overload relay FR2; the food waste control oil pump 31 is controlled by the AC contactor KM4 and protected by the thermal overload relay FR3; the food waste crusher 33 is controlled by the AC contactors KM5 and KM6 and protected by the thermal overload relay FR4; the food waste conveyor 34 is controlled by the AC contactors KM7 and KM8 and protected by the thermal overload relay FR5; the sewage storage tank drainage pump 35 is controlled by the AC contactor KM9 and protected by the thermal overload relay FR6; the sewage transfer tank lifting pump 36 is controlled by the AC contactor KM10 and protected by the thermal overload relay FR7; the spray pump 5 is controlled by the AC contactor KM11; the oil-water separation heater 37 is controlled by the AC contactor KM12.

[0036] Combination Figure 5, the corresponding signal output terminal of the temperature controller 38 is connected to the AC contactor KM12, and the corresponding signal input terminal is connected to the oil-water separation box temperature sensor 39; when the actual temperature of the oil-water separation box liquid is lower than the set value, the internal relay of the temperature controller 38 is energized, and the signal output terminal outputs an AC 220V voltage to the AC contactor KM12 coil, and the normally open end is closed, providing an AC 220V working voltage for the oil-water separation box heater 37, and starting heating; when the actual temperature of the oil-water separation box liquid reaches the set value, the internal relay of the temperature controller 38 is disconnected, the AC contactor KM12 coil is in a standby state, the normally open end is disconnected, and the oil-water separation box heater 37 stops working. In this example, the temperature controller adopts an instrument of model XMTG produced by Shanghai Turing Instrument Co., Ltd.

[0037] In view of the safety issues and ease of use during the garbage feeding operation, the kitchen garbage control handle 32 and the domestic garbage control handle 22 can be designed as movable handles, which can remotely operate the feeding of domestic garbage and kitchen garbage to ensure the safety of garbage feeding and processing. The rising operation button SB1 and the falling operation button SB2 of the domestic garbage control handle 22 are connected to the rising solenoid valve YV1 and the falling solenoid valve YV2 of the domestic garbage control oil pump 31 through relays KA1 and KA2, respectively, and the rise or fall of the domestic garbage control is realized by the garbage disposal control cabinet 1. The rising operation button SB3 and the falling operation button SB4 of the kitchen garbage control handle 32 are connected to the rising solenoid valve YV3 and the falling solenoid valve YV4 of the kitchen garbage control oil pump 31 through relays KA3 and KA4, respectively, and the rise or fall of the kitchen garbage control is realized by the garbage disposal control cabinet 1.

[0038] The water inlet tank solenoid valve YV5 is connected to the kitchen waste water inlet operation button SB7 on the garbage disposal control cabinet 1 through the AC contactor KM13.

In order to solve the problem of sewage discharge in the sewage storage tank, a button SB5 that can be manually operated for automatic discharge is also set on the control cabinet, which can discharge the sewage in the storage tank in real time.

[0039] The spray pump is connected to the three-position knob switch 131 for kitchen waste operation on the garbage disposal control cabinet 1 through the AC contactor KM11. Figure 6The spray pump is connected to the operating contact of the three-position knob switch 131 for operating the kitchen garbage, and is connected in parallel with the kitchen garbage conveyor 34. Only when the kitchen garbage conveyor 34 is in operation, the spray pump 5 will operate to complete the cleaning of the garbage bin, the hopper and the ground.

[0040] See also Figure 7 The control operation process of the garbage disposal equipment control system includes the following steps:

[0041] First, power on the control system and turn on the control loop indicator light HW7. Check whether the working indicators of each device are on and whether an alarm occurs. If the indicator light is not on or an alarm occurs, cut off the power and check whether there is a fault in the device circuit. Power on again after troubleshooting.

[0042] Secondly, before operating the three-position knob switch SA2 for kitchen waste operation, first operate the water inlet button SB7 to check whether there is water in the water inlet tank. If there is water, operate the three-position knob switch SA2 of the garbage disposal control cabinet 1 to the operation position, and the kitchen waste disposal equipment 3 is in operation. At this time, the kitchen waste crushing indicator light HR3, the kitchen waste conveying operation indicator light HR5, the kitchen waste spraying operation indicator light HR7, and the kitchen waste sewage operation indicator light HR9 are all on. The kitchen waste collected by the garbage bin is operated by operating the rising button SB3 of the kitchen waste control handle 32 to close the contacts of the relay KA3, provide a first AC 220V voltage to the kitchen waste control rising solenoid valve YV3, provide a second AC 220V voltage to the AC contactor KM4 coil, the AC contactor KM4 is normally closed, and an AC 380V voltage is provided to the kitchen waste control oil pump 31. When the garbage bin rises to a high position, the kitchen waste is fed into the hopper of the kitchen waste treatment device 3. On the contrary, the descending button SB4 of the kitchen waste control handle 32 is operated to close the contacts of the relay KA4, provide a first AC 220V voltage to the kitchen waste control descending solenoid valve YV4, provide a second AC 220V voltage to the AC contactor KM4 coil, the AC contactor KM4 is normally closed, and an AC 380V voltage is provided to the kitchen waste control oil pump 31. When the garbage bin is lowered to a low position, the kitchen waste is fed once.

[0043] After the food waste is reduced in volume and crushed, it will be separated from the solid and liquid, and the waste liquid will flow to the sewage transfer tank by itself. When the liquid level reaches a high level, the contact of the sewage transfer tank liquid level float SH1 is closed, and the signal is fed back to the sewage transfer tank pump relay KA7. Through the air delay head KT2 and the AC contactor KM10, the sewage transfer tank pump is operated for a period of time to complete the lifting of the waste liquid from the transfer tank to the oil-water separation tank; after a certain period of waiting, the oil-water separation of the waste liquid is completed, and the grease after the oil-water separation tank is discharged into the oil collection barrel through the oil discharge port. The grease can be recycled or composted on site, and the separated sewage overflows into the sewage storage tank. When the sewage level reaches a high level, the contact of the sewage storage tank liquid level float SH2 is closed, and the signal is fed back to the sewage storage tank pump relay KA6. Through the air delay head KT1 and the AC contactor KM9, the sewage storage tank pump is operated for a period of time to complete the discharge of sewage, and finally the solid-liquid separation, oil-water separation and automatic discharge of sewage of the food waste waste liquid are completed. When the sewage storage tank drainage pump 35 fails, the bimetallic strip of the main circuit of the thermal overload relay FR6 is deformed and the normally closed end is disconnected, the coil of the AC contactor KM9 is de-energized and the normally open end is disconnected, the sewage storage tank drainage pump 35 is de-energized and stops working, and at the same time, the normally open end of the thermal overload relay FR6 is closed, and the connected sewage storage tank drainage fault indicator HY6 lights up, thereby protecting the equipment from failure and outputting a fault indication.

[0044] When the feeding of food waste is completed, the spray pump 5 is started for cleaning and spraying. The water inlet tank is stored through the operation button SB7, through the air delay head KT3, the AC contactor KM13 contacts are closed, and the AC 220V voltage required by the water inlet solenoid valve YV5 is provided. The water inlet valve is closed after being opened for a period of time, and the water inlet tank completes the water storage function. Reset the rising operation button SB3 of the food waste control handle 32, start spraying, clean the garbage bin and hopper, and then operate the descending operation button SB4 of the food waste control handle 32, the food waste bin drops to the low position, and reset the descending operation button SB4 of the food waste control handle 32; finally, operate the three-position knob switch SA2 of the food waste operation operation to the stop position.

[0045] When the food waste crusher 33 fails, the bimetallic strip of the main circuit of the thermal overload relay FR4 is deformed and the normally closed end is disconnected, the coil of the AC contactor KM5 is powered off and the normally open end is disconnected, the food waste crusher 33 is powered off and stops working, and the food waste crushing fault indicator HY4 lights up; when the food waste conveyor 34 fails, the bimetallic strip of the main circuit of the thermal overload relay FR5 is deformed and the normally closed end is disconnected, the coil of the AC contactor KM7 is powered off and the normally open end is disconnected, the food waste conveyor 34 is powered off and stops working, and the food waste conveying fault indicator HY5 lights up, realizing the alarm prompt function.

[0046] When the three-position rotary switch SA1 for domestic waste operation is operated to the operation position, the domestic waste treatment equipment 2 is operated, and the domestic waste crushing operation indicator HR1 is lit. The rising operation button SB1 of the domestic waste control handle 22 is operated, and the domestic waste bin is raised to the high position, completing the domestic waste treatment. After treatment, the rising operation button SB1 of the domestic waste control handle 22 is reset, the descending operation button SB2 of the domestic waste control handle 22 is operated, and the domestic waste bin is lowered to the low position, the descending operation button SB2 of the domestic waste control handle 22 is reset, and the three-position rotary switch SA1 for domestic waste operation is operated to the stop position.

[0047] When the domestic waste crusher 23 fails, the bimetallic strip of the main circuit of the thermal overload relay FR2 is deformed and the normally closed end is disconnected, the coil of the AC contactor KM2 is de-energized and the normally open end is disconnected, the domestic waste crusher 23 is powered off and stops working, and the domestic waste crushing fault indicator light HY2 lights up, realizing the alarm prompt function.

[0048] When processing kitchen waste or domestic waste, it is necessary to determine whether an overload alarm occurs. When the kitchen waste processing causes the kitchen waste control oil pump 31 to be thermally overloaded, the bimetallic strip of the main circuit of the thermal overload relay FR3 is deformed, the normally closed end is disconnected, the AC contactor KM4 coil is powered off, the normally open end is disconnected, the kitchen waste control oil pump 31 is powered off, and stops working; at the same time, the normally open end of the thermal overload relay FR3 is closed, and the connected kitchen waste lifting fault indicator HY3 is lit, so that the equipment is protected from faults and the fault indication is output. Or the emergency stop button SB6 is pressed at the same time to achieve an emergency stop. After that, the thermal overload relay FR3 and the emergency stop button SB6 are reset, and the three-position knob switch SA2 for kitchen waste operation is operated to the reverse position, the kitchen waste processing equipment is reversed, and the kitchen waste crushing reverse indicator HR4 and the kitchen waste conveying reverse indicator HR6 are lit. At this time, it is determined whether the kitchen waste has been returned. If the return is completed, the three-position knob switch SA2 for kitchen waste operation is operated to the operation position again, and the kitchen waste feeding operation is repeated.

[0049] Similarly, when the domestic waste treatment causes the domestic waste control oil pump 21 to be thermally overloaded, the bimetallic strip of the main circuit of the thermal overload relay FR1 is deformed, the normally closed end is disconnected, the coil of the AC contactor KM1 is de-energized, the normally open end is disconnected, the domestic waste control oil pump 21 is de-energized, and stops working, and the domestic waste lifting fault indicator HY1 lights up; at the same time, the normally open end of the thermal overload relay FR1 is closed, and the connected domestic waste lifting fault indicator HY1 lights up, so that the equipment is protected from faults and the fault indication is output. Or press the emergency stop button SB6 at the same time to achieve an emergency stop. After that, reset the thermal overload relay FR1 and the emergency stop button SB6, operate the three-position knob switch SA1 of the domestic waste operation operation to the reverse position, the domestic waste treatment equipment is reversed, and the domestic waste crushing reversal indicator HR2 lights up. At this time, it is judged whether the domestic waste has been returned. If the return is completed, operate the three-position knob switch SA1 of the domestic waste operation operation to the operation position again, and repeat the domestic waste feeding operation.

[0050] The present invention can not only control the processing and return of domestic garbage and kitchen waste, but also realize active shutdown of domestic garbage and kitchen waste processing equipment when overloaded, completely avoiding the potential safety hazard caused by overload heating.
