DETAILED DESCRIPTION

The recovery tank liquid outlet 102 is connected to a thin syrup output pipe 12, and a recovery tank liquid outlet valve 13 is installed on the thin syrup output pipe 12.

[0028] A syrup mixing tank 2 for mixing syrup concentration is provided with a high-concentration syrup inlet 201 and a mixing port 202 on the top of the syrup mixing tank 2. The high-concentration syrup inlet 201 is connected to the high-concentration syrup tank through a high-concentration syrup delivery pipeline 21. A syrup pump 211 and a large syrup outlet valve 212 are installed on the high-concentration syrup delivery pipeline 21. The mixing port 202 is connected to a mixing pipeline 22.

The diameter of the high-concentration syrup delivery branch 25 is smaller than the diameter of the high-concentration syrup delivery pipeline 21. A small syrup outlet valve 251 is installed on the high-concentration syrup delivery branch 25.

[0029] In this embodiment, the syrup pump 211 is a twin-turbine syrup pump.

[0030] A mixing tank liquid outlet 204 is provided at the bottom of the syrup mixing tank 2, a sugar content sensor 4 is installed at the sugar content sensor interface 203, a detection probe of the sugar content sensor is connected to the water inlet pipe 23, a water inlet valve 231 is installed on the water inlet pipe 23, the mixing tank liquid outlet 204 is connected to the mixing tank liquid outlet pipe 24, a mixing tank outlet pipe 24 is installed with a mixing tank valve 241, and a liquid level sensor 5 is also installed on the syrup mixing tank 2.

[0031] A syrup storage tank 3 for storing prepared syrup has a storage tank liquid inlet 301 disposed on the top of the syrup storage tank 3 and a storage tank liquid outlet 302 disposed on the bottom of the syrup storage tank 3 for outputting the prepared syrup. The storage tank liquid inlet 301 is connected to a syrup input pipeline 31, on which a storage tank inlet valve 32 is installed. The storage tank liquid outlet 302 is connected to a syrup output pipeline 33, on which a storage tank outlet valve 34 is installed.

[0032] A circulation pump 6, one end of which is connected to an inlet circulation pipe 61, and the other end is connected to an outlet circulation pipe 62, a circulation flow control valve 63 is also installed on the outlet circulation pipe 62, the mixing tank outlet pipe 24 and the thin syrup output pipe 12 are connected in parallel to the inlet circulation pipe 61, and the mixing tank outlet pipe 24 and the syrup input pipe 31 are connected in series with the outlet circulation pipe 62.

When the water inlet valve 231 and the mixing tank valve 241 are opened, the first branch pipe 232 and the second branch pipe 233 are connected to the inlet circulation pipe 61, and water enters the syrup mixing tank 2 through the outlet circulation pipe 62.

[0034] PLC controller, sugar content sensor 4 and liquid level sensor 5 are electrically connected to the input port of the PLC controller, and the recovery tank liquid outlet valve 13, the inlet valve 221 of the blending tank, the water inlet valve 231, the outlet valve 241 of the blending tank, the inlet valve 32 of the storage tank, the circulation pump 6 and the syrup pump 211 are all electrically connected to the output port of the PLC controller.

[0035] The small sugar solution outlet valve 251 and the large sugar solution outlet valve 212 are also electrically connected to the PLC controller and controlled by the PLC controller.

[0036] For the convenience of observation, both the syrup mixing tank 2 and the syrup storage tank 3 are provided with windows, which are respectively a window 14 provided on the thin syrup recovery tank 1 , a window 26 provided on the syrup mixing tank 2 , and a window 35 provided on the syrup storage tank 3 .

[0037] In order to facilitate observation of the position of the syrup, there are two viewing windows 14, 26 and 35, which are arranged up and down to observe the high and low liquid levels.

[0038] The top of the syrup mixing tank 2 is provided with an atmosphere communication hole 27 and a manhole 28, and the top of the syrup mixing tank 2 is also provided with an automatic cleaning head 29 extending into the interior thereof.

[0039] The working principle of the present invention is as follows:

[0040] When starting production, first open the water inlet valve 231 to inject a certain amount of water to dilute the high-concentration sugar solution into the syrup preparation tank 2. The injection amount is detected by the liquid level sensor 5. When the injection amount reaches the set liquid level, the PLC controller outputs a control signal to close the water inlet valve 231, and the water injection is completed.

[0041] The PLC controller automatically opens the valve 241, the circulation pump 6 and the valve 221 of the syrup mixing tank 2 to circulate the dilution water in the syrup mixing tank 2, and at the same time opens the double turbine sugar solution pump 211 and the large valve 212 of the sugar solution outlet to inject the high-concentration sugar solution into the syrup mixing tank 2. The sugar solution concentration is detected by the sugar content sensor 4 and sent to the PLC controller. When the sugar solution concentration in the syrup mixing tank 2 is close to the set percentage concentration, the large valve 212 of the sugar solution outlet is closed, and the small valve 251 of the sugar solution outlet is opened, and the high-concentration sugar solution continues to enter the syrup mixing tank 2 through the small valve 251 of the sugar solution outlet. When the syrup concentration in the syrup mixing tank 2 reaches the set percentage concentration, the double turbine sugar solution pump 211 and the small valve 251 of the sugar solution outlet are closed, the valve 221 of the mixing tank inlet is closed, and the valve 32 of the storage tank inlet is opened, and the prepared syrup is injected into the syrup storage tank 3 for production use. The next automatic mixing of water and high-concentration sugar solution is the same as above.

[0042] After the prepared syrup is used, the concentration of the syrup decreases, and it can be recycled to the thin syrup recovery tank 1. Through the window 14, when a certain amount of thin syrup is recovered, it is transported to the syrup preparation tank 2 for preparation. This process is automatically controlled by the PLC controller. The steps are as follows: first, open the recovery tank outlet valve 13 and the inlet preparation tank valve 221, start the circulation pump 6, and the thin syrup is injected into the syrup preparation tank 2 through the thin syrup output pipe 12, the inlet circulation pipe 61, the outlet circulation pipe 62 and the preparation pipe 22.

[0043] The liquid level sensor 5 detects the liquid level of the syrup mixing tank 2 to obtain the injection amount of the thin syrup. When the injection of the thin syrup reaches the set liquid level, the injection is completed, the thin syrup recovery tank outlet valve 13 is closed, and the outlet valve 241 of the mixing tank is opened at the same time, so that the thin syrup circulates in the syrup mixing tank 2. Then the double turbine sugar liquid pump 211 and the small sugar liquid outlet valve 251 are opened to inject the high-concentration sugar liquid into the syrup mixing tank 2. The injection amount and the syrup concentration are detected by the liquid level sensor 5 and the sugar content sensor 4 respectively. When the syrup concentration in the syrup mixing tank 2 reaches the set percentage concentration, the double turbine sugar liquid pump 211 and the small sugar liquid outlet valve 251 are closed, the mixing tank inlet valve 221 is closed, and the storage tank inlet valve 32 is opened to inject the prepared syrup into the syrup storage tank 3 for production use. In continuous production, the next step of automatic mixing of thin syrup and high-concentration sugar liquid is the same as above.

[0044] In the present invention, the PLC controller is a commonly used controller in industrial control and belongs to the prior art. Therefore, technicians in this field can select the brand and model of the PLC controller according to production needs. The recovery tank liquid outlet valve 13, the inlet and dispensing tank valve 221, the water inlet valve 231, the dispensing tank valve 241, the inlet and storage tank valve 32, the circulating pump 6, the syrup pump 211, the large sugar solution outlet valve 212, and the small sugar solution outlet valve 251 are also commonly used electronic control components in the prior art. The solenoid valves and electric valves that can realize the above-mentioned functions in the prior art can be used as control valves on the recovery tank liquid outlet valve 13, the inlet and dispensing tank valve 221, the water inlet valve 231, the dispensing tank valve 241, the inlet and storage tank valve 32, the outlet and storage tank valve 34, the large sugar solution outlet valve 212, and the small sugar solution outlet valve 251 in the present invention.
