[0022] Working principle:

[0023] When the maltitol clean energy-saving pipeline conveying system is automatically running, the hot water pump 11 is started before the syrup feeding pump 14, the first syrup feeding pump 24 and the second syrup feeding pump 23 are started. After the syrup tank truck 13 is in place and the feeding hose is connected, one-key starting is performed. The system automatically starts the hot water pump 11 first, and then compares the liquid levels of the first syrup tank 19 and the second syrup tank 2 through the first liquid level sensor 21 and the second liquid level sensor 22, and selects the tank with the lowest liquid level to feed first. If the liquid level of the first syrup tank 19 is the lowest, the first feeding valve 15 is opened, the first feeding valve 15 is opened to the position, when the first temperature sensor 31 detects that the water temperature of the hot water return pipe of the syrup feeding pump 14 is higher than 40℃, the syrup feeding pump 14 is started, when the first liquid level sensor 21 detects that the liquid level in the first syrup tank 19 is higher than 2800mm, the syrup feeding pump 14 stops running, the first feeding valve 15 is closed, the second feeding valve 16 is automatically opened, the second feeding valve 16 is opened to the position, the syrup feeding pump 13 is started, and the second syrup tank 2 is fed. When the feeding is finished, the stop button is manually pressed, the syrup feeding pump 14 stops running, the second feeding valve 16 is closed, the system defaults that the first syrup tank 19 corresponds to the first feeding system, and the second syrup tank 2 corresponds to the second feeding system. The system automatically starts the hot water pump 11 first, and then compares the liquid levels of the first syrup tank 19 and the second syrup tank 2, and selects the system with the lowest liquid level to start first. If the liquid level of the first syrup tank 19 is the lowest, the first feeding system is started, the first feeding valve 15 is opened to the position, when the second temperature sensor 32 detects that the water temperature of the hot water return pipe through the first syrup feeding pump 24 and the second syrup feeding pump 23 is higher than 40℃, the first syrup feeding pump 24 is started, when the first syrup feeding pump 24 is full frequency, the pipeline pressure is still lower than the set pressure (1.0MPa), the second feeding system is automatically started, the second feeding valve 16 is opened to the position, the second syrup feeding pump 23 is started as a constant pressure pump, the second syrup feeding pump 23 is frequency-regulated to ensure that the feeding pipeline network pressure is the set pressure (1.0MPa), when the frequency of the second syrup feeding pump 23 is lower than 10%, the second syrup feeding pump 23 is stopped, and the first syrup feeding pump 24 continues to be frequency-regulated and constant-pressure, and the pressure signal comes from the first pressure sensor 25.

[0024] If the first liquid level sensor 21 detects that the liquid level in the first syrup tank 19 is below 150 mm, the first syrup feeding pump 24 is stopped, the first return valve 17 is closed, a first syrup tank 19 replenishment alarm is sent, and the second syrup feeding pump 23 is automatically started. If the second liquid level sensor 22 detects that the liquid level in the second syrup tank 2 is below 150 mm, the second syrup feeding pump 23 is stopped, the second return valve 18 is closed, a second syrup tank 2 replenishment alarm is sent, the system switches to the first feeding system, and the cycle continues. If the first feeding system fails, the system automatically switches to the second feeding system and sends a failure alarm. When the sum of the liquid levels in the first syrup tank 19 and the second syrup tank 2 is less than 2800 mm, a replenishment alarm is sent to remind the manufacturer to replenish the material. In the material flow calculation, the single pump full frequency state is 4 t / h, the actual flow and the pump frequency are in a linear relationship, the system can display the cumulative feeding amount and the current flow, and when the syrup is returned, the hot water pump 11 is started before the syrup return pump 3 is started. The second syrup feeding pump 23 can transport the material in the second syrup tank 2 to the sealed weighing area 26 for weighing. Similarly, the first syrup feeding pump 24 can transport the material in the first syrup tank 19 to the sealed weighing area 26 for weighing. After the material weighed by the sealed weighing area 26 enters the return liquid syrup tank 27, the material is transported back to the first syrup tank 19 through the first return valve 17 or the second return valve 18 by the syrup return pump 3. When the second pressure sensor 28 or the third pressure sensor 19 on the return liquid syrup tank 27 detects a pressure higher than 9.5 kg / cm2 / (the pressure can be adjusted to 8.0-9.5 kg / cm2, and the adjustment is made on site), the syrup return pump 3 is started when the third temperature sensor 33 detects that the water temperature of the hot water return pipe of the syrup return pump 3 is higher than 45℃. The syrup return pump 3 is stopped when the third pressure sensor 29 on the return liquid syrup tank 27 is lower than 7.5 kg / cm2.

[0025] When the maltitol clean energy-saving pipeline conveying system is operated manually, the syrup tank truck 13 is first positioned, the feeding hose is connected, and then the syrup tank is selected manually. If the first syrup tank 19 is selected, the first feeding valve 15 is opened to the position, the button is started, the system is automatically started, the hot water pump 11 is started, when the first temperature sensor 31 detects that the water temperature of the hot water return pipe of the syrup feeding pump 14 is higher than 40℃, the syrup feeding pump 14 is started, when the first liquid level sensor 21 detects that the liquid level in the first syrup tank 19 is higher than 2800mm, the syrup feeding pump 14 is stopped, manual operation is required to feed the next tank, the worker can select the first syrup tank 19 with the first syrup feeding pump 24 or the first syrup tank 19 with the second feeding system, the second syrup tank 2 with the second syrup feeding pump 23 or the second syrup tank 2 with the first feeding system, the corresponding tank return valve is opened after the pump and the tank are selected, the valve is opened to the position, the button is started, the system is automatically started, the hot water pump is started, when the second temperature sensor 32 detects that the water temperature of the hot water return pipe of the first syrup feeding pump 24 and the second syrup feeding pump 23 is higher than 40℃, if the first syrup feeding pump 24 is started, when the first liquid level sensor 21 detects that the liquid level in the first syrup tank 19 is lower than 150mm, the pump is stopped, the corresponding return valve is closed, and the corresponding tank feeding alarm is issued, the next feeding pump (single pump or double pump) is started manually, the first syrup feeding pump 24 and the second syrup feeding pump 23 are controlled by frequency conversion, the pump running frequency is automatically controlled by the first pressure sensor 25 to ensure that the feeding pipe network pressure is 10kg / cm2, the system fails and alarms, the fault pump is stopped, and the next pump needs to be manually switched.

[0026] When the syrup backflow is performed, the syrup backflow pump 3 is manually started and stopped, and the return bypass valve 34 is opened.
