Description

Technical Field

[0001] The utility model relates to the technical field of flow meter calibration devices, in particular to a flow meter calibration device used in a tobacco flavoring and feeding system. Background Art

[0002] The cigarette flavoring and feeding system is a system that applies "liquid" with fragrance or flavor to tobacco leaves during the production process of cigarettes. There are generally two methods of adding materials to cigarettes: spraying and dipping. The spraying method generally involves spraying liquid with steam after the leaves enter the moistening drum, so that the liquid fully penetrates the leaves. In order to achieve the purpose of improving the quality of tobacco, the spraying method must strictly ensure the uniformity of the feeding, otherwise the effect of the feeding will be reduced. If the feeding is uneven, the quality of cigarettes with insufficient feeding will not be improved, and the feeding effect will not be achieved; if the feeding is too much and it is not easy to dehumidify, the tobacco with more sugar will have yellow spots after rolling. Therefore, it is particularly important to control the flow rate of the liquid in the flavoring and feeding system. At present, flow meters are usually used for measurement, so that more accurate liquid can be matched according to the amount of tobacco leaves to produce high-quality cigarettes.

[0003] The metering accuracy of the flowmeter directly affects the accuracy of the addition of liquids. For example, if one of the liquids is used for flavoring and adding, the ratio of this liquid to other liquids will not meet the standard due to inaccurate metering by the flowmeter, which will result in all cigarettes in this batch not meeting the standard. In addition, due to the presence of water and moisture in the additives, unqualified cigarettes cannot be processed and recycled, resulting in material waste and increased cigarette production costs. Therefore, in the cigarette flavoring and adding system, the metering accuracy of the flowmeter is the key to ensuring the normal operation of the cigarette flavoring and adding system. It is particularly important to regularly calibrate or more accurately calibrate the accuracy of the flowmeter in the cigarette flavoring and adding system.

[0004] At present, the regular calibration method of the flavoring and feeding flowmeter is to first reset the flowmeter to be tested, start the liquid circulation system, fill the flowmeter pipeline with liquid, let the liquid flow through the flowmeter and fill the entire flavoring and feeding system pipeline; after the calibration liquid is filled, start the flowmeter calibration function of the flavoring and feeding system, release the liquid that has passed through the flowmeter and weigh it; by comparing the manual weighing result with the metering result of the flowmeter, the metering accuracy of the flowmeter under test can be determined. Since the liquid discharged from the flowmeter pipeline needs to be manually loaded into a container during the filling process, and the liquid needs to be manually loaded and weighed during the calibration process, especially in the working conditions where multiple calibrations are required to reduce errors, it is necessary to repeatedly switch the liquid, or to repeat the operation multiple times when calibrating multiple flowmeters separately, which not only takes a long time, but also has cumbersome procedures and inconvenient operations.

The liquid in the fourth liquid pipe is switched to flow into the third liquid pipe, that is, the third liquid pipe and the fourth liquid pipe are connected, so that the measuring liquid storage tank receives the liquid discharged from the fourth liquid pipe by the flow meter tube, and completes weighing on the weight meter.

[0035] It should be noted that the first liquid port 21 or the first liquid pipe 23 is provided with a switch, such as a quick connector or a water valve, which can manually open the water valve to achieve liquid circulation in the first liquid port 21 or the first liquid pipe 23; the flow meter tube refers to the pipeline through which liquid needs to flow for calibrating the flowmeter.

[0036] Reference to the method of use of the utility model: load the calibration liquid in the circulating liquid storage tank 2, connect the first liquid pipe 23 to the liquid inlet end of the flow meter tube, connect the two ends of the second liquid pipe 24 to the pipeline control valve 5 and the second liquid port 22, connect the third liquid pipe 32 to the third liquid port 31, and connect the fourth liquid pipe 51 to the liquid outlet end of the flow meter tube; open the pipeline control valve 5 through the controller 52, open the water valve of the first liquid port 21, and then make the liquid in the circulating liquid storage tank 2 flow to the flow meter tube through the first liquid port 21, and then flow out from the liquid outlet end of the flow meter tube to the fourth liquid pipe 51, and pass through the control valve The direction of the pipeline flows from the second liquid pipe 24 back to the circulation storage tank 2, completing the pre-filling of the flow meter tube with liquid; after the pre-filling of the liquid is completed, the flow meter test start button of the control platform of the flavoring and feeding system is triggered, and the pipeline control valve 5 is controlled by the controller 52 to switch the liquid outflowing from the fourth liquid pipe 51 from the original second liquid pipe 24 to the third liquid pipe 32, and then the calibration liquid discharged from the flow meter tube is passed into the measuring storage tank 3, and weighed on the weight meter 4, the real-time weighing data of the weight meter 4 and the flow data of the flow meter are read, and the two are compared with each other to obtain the calibration result, completing a calibration of a flow meter.

[0037] In the case where recalibration or multiple calibrations are required, the liquid in the measuring liquid storage tank 3 is firstly discharged. It should be noted that the liquid in the measuring liquid storage tank 3 can be discharged by a pump or suction, or by providing a discharge port in the measuring liquid storage tank 3 to discharge the weighed liquid through the discharge port; specifically, Figure 1 As shown, the measuring liquid storage tank 3 is provided with a fourth liquid port 33, and the fourth liquid port 33 can be connected to the circulating liquid storage tank 2 through an on-off valve; Figure 2 As shown, the top of the measuring liquid storage tank 3 is uncovered, the top is directly connected to the atmosphere, and a quick connector is provided at the bottom to form a fourth liquid port 33; the quick connector is provided with a manual valve 331 pointing vertically downward; correspondingly, an opening is provided at the top of the circulating liquid storage tank 2 at a position opposite to the fourth liquid port 33; the circulating liquid storage tank 2 is configured so that the top opening is directly connected to the atmosphere, so that the fourth liquid port 33 is directly opposite to the opening of the circulating liquid storage tank 2, so that the liquid in the measuring liquid storage tank 3 can be directly discharged into the circulating liquid storage tank 2 through the fourth liquid port 33.

The second liquid pipe 24 then continues to fill the flow meter tube through the first liquid pipe 23, thereby realizing the cyclic filling of the calibration liquid. When re-calibration is required, the flow meter test start button on the control platform of the flavoring and feeding system is triggered again, and the pipeline control valve 5 is controlled by the controller 52 to switch the liquid flowing out of the fourth liquid pipe 51 from the original second liquid pipe 24 to the third liquid pipe 32, thereby realizing the re-calibration process.

[0044] It should be noted that the pipeline control valve 5 is understood to be a valve with a three-way pipe, which can be set as a pipeline control valve 5 including a reversing valve and an on-off valve, and can also be set as a pneumatic valve, the driving medium of the pneumatic valve is compressed air; specifically, the driving medium of the pneumatic valve can be air or nitrogen, and the pipeline control valve 5 is controlled by a controller 52, and the controller 52 is connected to the control platform of the flavoring and feeding system through an electrical signal, so that the enable signal of the pipeline control valve 5 can be triggered by the "flow meter test start" button on the control platform screen of the flavoring and feeding system.
