[0032] Meanwhile, the control device also includes a control loop, forming a secondary circuit. An emergency stop button SB6 is designed in the secondary circuit. When the equipment malfunctions, pressing the emergency stop button will stop the equipment with one key, and all waste treatment equipment will stop working, thus realizing the control of the waste treatment equipment.

[0033] The waste disposal equipment control device is also designed with an air conditioner 41, an electric heater, an electric ventilation fan 44, and lighting equipment 6. When the working temperature is below a certain temperature, the air conditioner 41 can be turned on in heating mode and the electric heater to raise the indoor temperature; when the working temperature is above a certain temperature, the air conditioner 41 can be turned on in cooling mode to lower the indoor temperature, thus maintaining the indoor temperature; when ventilation is required, the electric ventilation fan 44 can be turned on to intake and exhaust air in the workplace, achieving air exchange and maintaining air circulation in the workplace; turning on the lighting equipment 6 allows for operation in low light conditions or at night, meeting the working needs of adapting to different environments.

[0034] See Figure 4 The waste treatment control cabinet 1 provides AC 380V operating voltage for the domestic waste control oil pump 21, domestic waste crusher 23, kitchen waste control oil pump 31, kitchen waste crusher 33, kitchen waste conveyor 34, sewage transfer tank lift pump 36, and sewage storage tank drain pump 35.

The power supply to the domestic waste treatment equipment 2, kitchen waste treatment equipment 3, control circuit, lighting equipment 6, and environmental control equipment 4 is controlled by a circuit breaker and connected in parallel with an indicator light to display the operating status.

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

[0036] Combination Figure 5The 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 separator temperature sensor 39. When the actual temperature of the liquid in the oil-water separator is lower than the set value, the internal relay of the temperature controller 38 is activated, and the signal output terminal outputs AC 220V voltage to the coil of the AC contactor KM12. The normally open terminal closes, providing AC 220V operating voltage to the oil-water separator heater 37, and heating begins. When the actual temperature of the liquid in the oil-water separator reaches the set value, the internal relay of the temperature controller 38 is deactivated, the coil of the AC contactor KM12 is in standby mode, the normally open terminal is open, and the oil-water separator heater 37 stops working. In this example, the temperature controller is an XMTG model instrument manufactured by Shanghai Turing Instrument Co., Ltd.

[0037] To address safety and ease of use issues during waste disposal, the control handles 32 for food waste and 22 for household waste can be designed as movable handles, enabling remote operation of food waste and household waste disposal while ensuring safety during disposal and processing. The up operation button SB1 and down operation button SB2 of the household waste control handle 22 are connected to the up solenoid valve YV1 and down solenoid valve YV2 of the household waste control oil pump 31 via relays KA1 and KA2, respectively, allowing the waste disposal control cabinet 1 to control the raising or lowering of the household waste. Similarly, the up operation button SB3 and down operation button SB4 of the food waste control handle 32 are connected to the up solenoid valve YV3 and down solenoid valve YV4 of the food waste control oil pump 31 via relays KA3 and KA4, respectively, allowing the waste disposal control cabinet 1 to control the raising or lowering of the food waste.

[0038] The inlet tank solenoid valve YV5 is connected to the kitchen waste inlet operation button SB7 on the waste treatment control cabinet 1 via AC contactor KM13. The sewage transfer tank level float SH1 detects the high / low level and controls the operation / stop of the sewage transfer tank lift pump via air delay head KT2, AC contactor KM10, and sewage transfer tank pump relay KA7. The sewage storage tank level float SH2 detects the high / low level and controls the operation / stop of the sewage storage tank drain pump via air delay head KT1, AC contactor KM9, and sewage storage tank pump relay KA6. For sewage discharge from the sewage storage tank, a manually operable automatic discharge button SB5 is also installed on the control cabinet, enabling real-time discharge of sewage from the storage tank.

[0039] The spray pump is connected to the three-position rotary switch 131 for operating kitchen waste on the waste treatment control cabinet 1 via an AC contactor KM11. Figure 6The spray pump is connected to the operating contacts of the three-position rotary switch 131 for the operation of the kitchen waste, and is connected in parallel with the kitchen waste conveyor 34. The spray pump 5 only operates when the kitchen waste conveyor 34 is in operation, to complete the cleaning of the garbage can, hopper and ground.

[0040] See Figure 7 The control operation process of the waste treatment equipment control device includes the following steps:

[0041] First, power on the control system. The control circuit indicator HW7 will light up. Check whether the working indicator lights of each device are lit up and whether any alarms have occurred. If the indicator lights are not lit up or an alarm has occurred, perform a power-off operation, check whether there is a fault in the equipment circuit, and power on again after troubleshooting.

[0042] Secondly, before operating the three-position rotary switch SA2 for food waste processing, first operate the water inlet button SB7 to check if there is water in the water inlet tank. If there is water, operate the three-position rotary switch SA2 of the waste processing control cabinet 1 to the running position. The food waste processing equipment 3 will be in operation. At this time, the food waste crushing indicator HR3, the food waste conveying operation indicator HR5, the food waste spraying operation indicator HR7, and the food waste sewage operation indicator HR9 will all light up. The kitchen waste collected in the trash can is fed into the hopper of the kitchen waste processing equipment 3 by operating the up button SB3 on the kitchen waste control handle 32. This closes the contacts of relay KA3, providing a first path of 220V AC voltage to the kitchen waste control up solenoid valve YV3 and a second path of 220V AC voltage to the coil of AC contactor KM4. The normally open terminal of AC contactor KM4 closes, providing a 380V AC voltage to the kitchen waste control oil pump 31. When the trash can rises to the high position, the kitchen waste is fed into the hopper of the kitchen waste processing equipment 3. Conversely, operating the down button SB4 on the kitchen waste control handle 32 closes the contacts of relay KA4, providing a first path of 220V AC voltage to the kitchen waste control down solenoid valve YV4 and a second path of 220V AC voltage to the coil of AC contactor KM4. The normally open terminal of AC contactor KM4 closes, providing a 380V AC voltage to the kitchen waste control oil pump 31. When the trash can falls to the low position, one feeding of kitchen waste is completed.

[0043] After the food waste is reduced in volume and pulverized, it undergoes solid-liquid separation. The waste liquid flows by gravity to the sewage transfer tank. When the liquid level reaches the high level, the contact of the sewage transfer tank level float SH1 closes, and the signal is fed back to the sewage transfer tank water pump relay KA7. Through the air delay head KT2 and the AC contactor KM10, the sewage transfer tank water pump runs for a period of time, completing the lifting of the waste liquid from the transfer tank to the oil-water separation tank. After a certain waiting time, the oil and water separation of the waste liquid is completed. The grease after passing through the oil-water separation tank is discharged into the oil collection tank through the oil drain. The grease can be recycled or composted on-site. The separated sewage overflows into the sewage storage tank. When the sewage level reaches the high level, the contact of the sewage storage tank level float SH2 closes, and the signal is fed back to the sewage storage tank water pump relay KA6. Through the air delay head KT1 and the AC contactor KM9, the sewage storage tank water pump runs for a period of time, completing the sewage discharge. Finally, the food waste waste liquid is separated from the solid-liquid separation, the oil-water separation, and the sewage is automatically discharged. When the sewage storage tank drainage pump 35 malfunctions, the bimetallic strip of the main circuit of the thermal overload relay FR6 deforms and its normally closed terminal opens. The coil of the AC contactor KM9 is de-energized and its normally open terminal opens, de-energizing the sewage storage tank drainage pump 35 and stopping its operation. At the same time, the normally open terminal of the thermal overload relay FR6 closes, and the connected sewage storage tank drainage fault indicator HY6 lights up, thus protecting the equipment in case of failure and providing a fault indication.

[0044] When the food waste is fed in, the spray pump 5 is started for cleaning and spraying. Water is stored in the inlet tank via operation button SB7, which, through the air delay head KT3, closes the contacts of the AC contactor KM13, providing the required 220V AC voltage to the inlet solenoid valve YV5. After a period of time, the inlet valve closes, completing the water storage function of the inlet tank. Resetting the up operation button SB3 on the food waste control handle 32 activates the spraying, cleaning the waste bin and hopper. Then, operating the down operation button SB4 on the food waste control handle 32 lowers the food waste bin to the low position. Resetting the down operation button SB4 on the food waste control handle 32 again; finally, operating the three-position rotary switch SA2 to the stop position.

[0045] When the food waste shredder 33 malfunctions, the bimetallic strip in the main circuit of the thermal overload relay FR4 deforms and its normally closed terminal opens, the coil of the AC contactor KM5 is de-energized and its normally open terminal opens, the food waste shredder 33 is de-energized and stops working, and the food waste shredder fault indicator HY4 illuminates; when the food waste conveyor 34 malfunctions, the bimetallic strip in the main circuit of the thermal overload relay FR5 deforms and its normally closed terminal opens, the coil of the AC contactor KM7 is de-energized and its normally open terminal opens, the food waste conveyor 34 is de-energized and stops working, and the food waste conveying fault indicator HY5 illuminates, realizing the alarm function.

[0046] When the three-position rotary switch SA1 for the household waste operation is set to the "Run" position, the household waste processing equipment 2 starts operating, and the household waste crushing operation indicator HR1 illuminates. Operating the "Up" button SB1 on the household waste control handle 22 raises the household waste bin to the high position, completing the processing of the household waste. After processing, resetting the "Up" button SB1 on the household waste control handle 22, operating the "Down" button SB2 on the household waste control handle 22 lowers the household waste bin to the low position, resetting the "Down" button SB2 on the household waste control handle 22, and finally, operating the three-position rotary switch SA1 to the "Stop" position.

[0047] When the municipal solid waste shredder 23 malfunctions, the bimetallic strip of the thermal overload relay FR2 deforms and its normally closed terminal opens, the coil of the AC contactor KM2 is de-energized and its normally open terminal opens, the municipal solid waste shredder 23 is de-energized and stops working, and the municipal solid waste shredder fault indicator HY2 lights up, realizing the alarm prompt function.

[0048] When processing food waste or household waste, it is necessary to determine whether an overload alarm has occurred. When processing food waste causes a thermal overload in the food waste control oil pump 31, the bimetallic strip in the main circuit of the thermal overload relay FR3 deforms, the normally closed terminal opens, the coil of the AC contactor KM4 is de-energized, the normally open terminal opens, the food waste control oil pump 31 is de-energized and stops working; at the same time, the normally open terminal of the thermal overload relay FR3 closes, the connected food waste lifting fault indicator HY3 lights up, realizing the protection of the equipment in case of failure and outputting a fault indication. Alternatively, the emergency stop button SB6 can be pressed simultaneously to achieve an emergency stop. Afterwards, reset the thermal overload relay FR3 and the emergency stop button SB6, operate the three-position rotary switch SA2 of the food waste operation to the reverse position, the food waste processing equipment reverses, the food waste crushing reverse indicator HR4 and the food waste conveying reverse indicator HR6 light up, at this time it is determined whether the food waste has been unloaded. If the unloading is completed, operate the three-position rotary switch SA2 of the food waste operation to the running position again to repeat the food waste feeding operation.

[0049] Similarly, when the handling of domestic waste causes thermal overload of the domestic waste control oil pump 21, the bimetallic strip in the main circuit of the thermal overload relay FR1 deforms, the normally closed terminal opens, the coil of the AC contactor KM1 is de-energized, the normally open terminal opens, 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 terminal of the thermal overload relay FR1 closes, and the connected domestic waste lifting fault indicator HY1 lights up, realizing the protection of the equipment in case of failure and outputting a fault indication. Alternatively, the emergency stop button SB6 can be pressed simultaneously to achieve an emergency stop. After that, the thermal overload relay FR1 and the emergency stop button SB6 are reset, and the domestic waste operation three-position knob switch SA1 is operated to the reverse position. The domestic waste handling equipment reverses, and the domestic waste crushing reverse indicator HR2 lights up. At this time, it is determined whether the domestic waste has been unloaded. If the unloading is completed, the domestic waste operation three-position knob switch SA1 is operated to the running position to repeat the domestic waste feeding operation.

[0050] This invention can not only control the processing and return of domestic waste and kitchen waste, but also enable the domestic waste and kitchen waste processing equipment to automatically stop when overloaded, completely avoiding safety hazards caused by overheating due to overload.
