Usually, the wine tanks are set in the storage workshop, and the temporary storage tanks and brewing equipment are set in the brewing workshop. The equipment is connected by a conveying pipe network, and the pipe network structure is complex and the distance is long. The conveying method of the conveying system is: after the wine delivery instruction is issued, the liquor is first transported from the wine tank to the temporary storage tank, and then the liquor is quantitatively transported from the temporary storage tank to the brewing equipment according to the brewing needs. When the temporary storage tank and the brewing equipment are both normal pressure equipment, due to the lack of pressure control of the conveying pipe network, the flow rate and pressure in the conveying pipeline in the early stage of liquor delivery are unstable. In this environment, the currently used flow meter cannot achieve accurate measurement of the delivery volume, resulting in inaccurate amount of liquor finally input into the brewing equipment, affecting the brewing efficiency.

[0026] Example

[0027] like Figure 1As shown, the constant pressure delivery system B for liquor brewing described in this embodiment specifically includes a controller, a first valve 1, a second valve 5, a third valve 11, a variable frequency delivery pump 4, a liquid level meter LS, a check valve 7, a mass flow meter FM, a water hammer elimination device 8, a first pressure detection device 6 and a second pressure detection device 10; the openings of the first valve 1, the second valve 5 and the third valve 11 are all adjustable; the first pressure detection device 6 and the second pressure detection device 10 are pressure sensors PT, which are used to monitor the pressure of each pipeline in the constant pressure delivery system pipeline network 2.

[0028] like Figure 2 As shown, the liquid inlet of the first valve 1 is connected to the wine tank outlet valve C provided on the wine tank A through a pipeline, the liquid outlet of the first valve 1 is connected to the liquid inlet of the variable frequency delivery pump 4 through a pipeline, the liquid outlet of the variable frequency delivery pump 4 is connected to the liquid inlet of the second valve 5 through a pipeline, the liquid outlet of the second valve 5 is connected to the liquid inlet of the third valve 11, and the liquid outlet of the third valve 11 is connected to the liquid inlet of the brewing equipment;

[0029] The liquid level meter LS is arranged on one side of the liquid inlet of the variable frequency delivery pump 4, and is used to detect the liquid level in the pipeline at one end of the liquid inlet of the variable frequency delivery pump 4; the check valve 7 is arranged on the pipeline between the second valve 5 and the third valve 11; the first pressure detection device is arranged in the pipeline between the variable frequency delivery pump 4 and the second valve 5, and is used to detect the operating pressure of the variable frequency delivery pump; the second pressure detection device is arranged inside the pipeline between the second valve 5 and the third valve 11, and is close to the third valve 11, and is used to detect the real-time pressure in the constant pressure delivery system pipeline network 2.

[0030] The first valve 1, the second valve 5, the third valve 11, the variable frequency delivery pump 4, the liquid level meter LS, the first pressure detection device 6, and the second pressure detection device 10 are all electrically connected to the controller.

[0031] As a further optimization, the constant pressure delivery system B also includes a water hammer elimination device 8 for eliminating the water hammer effect in the pipeline network of each wine delivery system.

[0032] As a further optimization, the liquid inlet of the third valve 11 is also provided with a mass flowmeter FM for measuring the amount of wine input into the brewing equipment. Due to the selection of the mass flowmeter, the front end pipeline of the mass flowmeter is reduced in diameter from 100L1E to 50L1E.

[0033] As a further optimization, in the constant pressure delivery system B, except for the front end of the flow meter which uses a DN50 stainless steel pipe due to selection reasons, all other pipes involved are DN100 stainless steel pipes.

[0034] The constant pressure control method of the constant pressure conveying system B for liquor brewing is as follows:

[0035] like Figure 3 As shown, when the constant pressure delivery system B is in the termination state where the system is not started or the operation is terminated, the pressure value of the constant pressure delivery system B is the set value; the user inputs a wine delivery instruction, and the controller receives the instruction; the controller controls the third valve 11 to open, connecting the brewing equipment at one end of the liquid outlet of the third valve 11, and the second pressure detection device 10 detects that the pressure of the wine delivery network drops and is lower than the set value, and the controller opens the wine tank wine outlet valve C, the first valve 1, and the second valve 5 to connect the wine tank A, the constant pressure delivery system B, and the brewing equipment at one end of the liquid outlet of the third valve 11; the liquid level meter LS detects the liquid level in the pipeline on the side of the liquid inlet of the variable frequency delivery pump 4. If the liquid level meter LS detects that the liquid level in the pipeline at one end of the liquid inlet of the variable frequency delivery pump 4 meets the minimum liquid level of the operation of the variable frequency delivery pump 4, the controller controls the variable frequency delivery pump 4 to start running, and the constant pressure delivery system B starts to deliver wine. The wine delivery process controls the wine delivery flow rate and the pressure in the pipeline of the constant pressure delivery system B through the speed change of the variable frequency delivery pump 4, and maintains the pressure in the pipeline of the constant pressure delivery system B within the pressure range required by the production process.

[0036] During the wine delivery process of the constant pressure delivery system B, the first pressure detection device 6 and the second pressure detection device 10 monitor the pressure of the constant pressure delivery system B. If the pressure monitored by the pressure detection device meets the requirements of the production process for the pipeline pressure of the wine delivery process, normal wine delivery is carried out; if the pressure in the pipeline monitored by the pressure detection device is lower than the lower limit requirement of the production process for the pipeline pressure of the wine delivery process, the system determines that there is a leak in the pipeline, and the controller starts the constant pressure delivery system B to execute the pipeline leakage disposal procedure.

[0037] When the amount of wine in the brewing equipment is about to reach the set amount, the speed of the variable frequency delivery pump 4 is reduced to ensure the accuracy of the measurement value of the amount of wine input into the brewing equipment by the mass flow meter FM. After the mass flow meter FM detects that the accumulated amount of wine has reached the set amount of wine at a certain moment, the controller closes the third valve 11 until the second pressure detection device monitors that the pressure of a section of the pipeline network of the constant pressure delivery system B close to the brewing equipment reaches or is slightly higher than the set constant pressure value, and then closes the variable frequency delivery pump 4 first, and then closes the second valve 5, the first valve 1 and the wine tank wine outlet valve C in sequence.

[0038] When the constant pressure delivery system B is in operation, if the pressure sensor detects that the pipeline pressure in the constant pressure delivery system B decreases, the approximate location of the leakage point is judged based on the pressure data uploaded by the pressure detection devices at different positions. If the first pressure detection device 6 detects that the pressure is too low, the possible leakage point is at the second valve 5 or the flange connection; if the second pressure detection device 10 detects that the pressure is too low, the possible leakage point is at the third valve 11 or the flange connection; after detecting the pipeline leakage, the controller controls the variable frequency delivery pump 4 to stop running, and closes the third valve 11, the second valve 5, the first valve 1 and the wine tank outlet valve C in sequence, and the constant pressure delivery system B stops running.

[0039] When the constant pressure delivery system B is not in operation, the pipe network is filled with liquor. The pipe network pressure in the constant pressure delivery system B is a constant value set according to the pipe network structure and experience. The leakage detection of the pipe network in the non-operating state is as follows: Figure 4 As shown, the controller receives in real time the pressure values ​​of different positions of the pipeline in the constant pressure transmission system B detected by the first pressure detection device 6 and the second pressure detection device 10. After receiving the abnormal pressure data, the controller eliminates the abnormal data and analyzes whether there is an obvious downward trend in the pipeline pressure data or whether the pressure is continuously lower than the set constant pressure value. If so, the controller determines the leakage point based on the position of the pressure detection device that detects the pressure abnormality and the pressure analysis result, and issues a pipeline leakage warning.
