Description

Technical Field

[0001] This utility model relates to the field of cigarette manufacturing, and in particular to a monitoring system for the feeding pipeline in a spice kitchen. Background Technology

[0002] Currently, the flavoring liquids used in tobacco processing production lines are dispensed from the flavor kitchen. The flavor kitchen system meets the storage requirements of the flavoring raw materials needed for cigarette production, realizes the function of preparing the required flavorings and sugars according to production and formula requirements, and meets the storage and dispensing requirements of finished flavorings and sugars.

[0003] The production site requests materials based on the production grade and quantity. After receiving the request signal, the spice kitchen confirms and compares the information before sending the liquid materials. The system then automatically dispenses the materials to meet the on-site material needs. Due to weather changes and sediment in the liquid materials, particles and sediment in the dispensing pipeline can easily cause blockages in the filter tank and pipelines. Blockages in the filter tank and pipelines can lead to uneven dispensing or even prevent the liquid materials from being delivered, affecting the production process. Furthermore, it can cause the liquid material delivery pump to run idle for extended periods, resulting in overheating and triggering the overcurrent protection of the frequency converter controlling the pump's operation.

[0004] Because the liquid conveying pipeline is long, sometimes reaching hundreds of meters, if the blockage cannot be identified in time, the disassembly and reassembly of the liquid pipeline and filter tank will take a long time. This will not only cause the frequency converter to alarm and require manual reset by professionals, but also affect production efficiency due to the long-term equipment maintenance. In addition, there is also the risk of liquid contamination. Utility Model Content

[0005] In view of the above, the present invention aims to provide a spice kitchen feed pipeline monitoring system to solve the aforementioned technical problems.

[0006] The technical solution adopted in this utility model is as follows:

[0007] This utility model provides a spice kitchen dispensing pipeline monitoring system, including: a first solenoid valve connected to a cleaning water source, a second solenoid valve connected to a compressed air source, and the first solenoid valve, the second solenoid valve, and the liquid storage tank are connected to the front end of the dispensing pipeline through a first three-way valve.

[0008] A first electromagnetic flowmeter and a second electromagnetic flowmeter are installed before and after the liquid delivery pump in the feeding pipeline. The first electromagnetic flowmeter is used to detect the blockage of the feeding pipeline between the liquid storage tank and the liquid delivery pump, and the second electromagnetic flowmeter is used to detect the blockage of the feeding pipeline between the liquid delivery pump and the field equipment.

[0009] In at least one possible implementation, the monitoring system further includes: a second three-way valve, which is connected to the feeding pipeline, the field equipment, and the discharge pipeline.

[0010] In at least one of the possible implementations, a barrel filter is installed before the feed pump to form a two-stage filtration mechanism for the feed liquid before the pump.

[0011] In at least one of the possible implementations, a filter screen is installed inside the liquid storage tank.

[0012] In at least one of the possible implementations, the filter screen is installed at the upper end of the liquid storage tank and uses a planar filter screen structure with a detachable mechanism.

[0013] In at least one possible implementation, the monitoring system further includes an audible and visual alarm device, which is associated with electrical signals of the first electromagnetic flowmeter and the second electromagnetic flowmeter.

[0014] Compared with existing technologies, the main design concept of this utility model lies in reliably detecting conveyor blockages during the material dispensing process and clearing them using a water-washing and air-blowing method, thereby ensuring that the spice kitchen can quickly send the liquid material to the production site storage tanks for production. Specifically, a first solenoid valve connected to the cleaning water source and a second solenoid valve connected to the compressed air source are connected to the front end of the dispensing pipeline via a first three-way valve. A first electromagnetic flow meter and a second electromagnetic flow meter are installed before and after the liquid delivery pump in the dispensing pipeline, respectively. The first electromagnetic flow meter is used to detect blockages in the dispensing pipeline between the liquid storage tank and the liquid delivery pump, and the second electromagnetic flow meter is used to detect blockages in the dispensing pipeline between the liquid delivery pump and the field equipment. This utility model effectively avoids filter and pipeline blockages, ensuring stable dispensing flow control and product quality while reliably reducing equipment damage rates and preventing contamination and loss of liquid material due to equipment maintenance. Attached Figure Description

[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the utility model will be further described below with reference to the accompanying drawings, wherein:

[0016] Figure 1 This is a schematic diagram of a spice kitchen dispensing pipeline monitoring system provided in an embodiment of the present invention. Detailed Implementation

[0017] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0018] This utility model proposes an embodiment of a spice kitchen dispensing pipeline monitoring system, specifically, as follows: Figure 1 As shown, it includes: a first solenoid valve 1 connected to the cleaning water source, a second solenoid valve 2 connected to the compressed air source, and the first solenoid valve 1, the second solenoid valve 2 and the material storage tank 6 are connected to the front end of the feeding pipeline through the first three-way valve 3.

[0019] To elaborate, the first solenoid valve 1 is electrically connected to the original control unit (PLC) in the spice kitchen system to control the connection status between the cleaning water circuit and the dispensing pipe. After the first solenoid valve 1 is opened, the cleaning water source provides clean water to the dispensing pipe for pipe cleaning, which can prevent different liquids from mixing in the pipe.

[0020] The second solenoid valve 2 is electrically connected to the original control unit (PLC) in the spice kitchen system to control the connection status between the compressed air source pipeline and the dispensing pipeline. After the second solenoid valve 2 is opened, the compressed air source provides air at a predetermined pressure to the dispensing pipeline to purge the liquid in the pipeline or clean the cleaning water in the pipeline. This can prevent the liquid from mixing with water during secondary dispensing and, in conjunction with water cleaning, ensure the cleanliness of the dispensing pipeline.

[0021] Regarding the first three-way valve 3, it can be installed at the discharge end of the liquid storage tank 6. Based on the different position states of the first three-way valve 3, it can switch between liquid delivery and water / air cleaning.

[0022] Continuing from the previous text, a first electromagnetic flowmeter 7 and a second electromagnetic flowmeter 10 are installed before and after the liquid delivery pump 9 in the dispensing pipeline, respectively. The first electromagnetic flowmeter 7 is used to detect the blockage of the dispensing pipeline between the liquid storage tank 6 and the liquid delivery pump 9, and the second electromagnetic flowmeter 10 is used to detect the blockage of the dispensing pipeline between the liquid delivery pump 9 and the field equipment 11 (the field equipment includes the field material handling machine). Detecting blockages by flow rate is a mature technology; for example, if the measured flow rate is lower than a set value, it indicates that there is a blockage in this section of the pipeline. This utility model will not elaborate on this, but it can be added that the concept of the above embodiment is to effectively monitor and eliminate pipeline blockages, thereby achieving the goal of preventing blockages in advance. The dispensing pipeline is divided into sections for blockage detection, avoiding the problem of difficulty in locating the blockage in long pipelines.

[0023] To further prevent clogging, a filter screen 5 can be installed inside the liquid storage tank 6 to filter impurities and crystals in the liquid. Specifically, the filter screen 5 can be installed at the upper end of the liquid storage tank 6 and uses a flat filter screen structure with a detachable mechanism, thereby effectively removing impurities from the liquid at the front end and preventing clogging in the pipeline at the rear end.

[0024] It can also be added that, in some other preferred embodiments, a barrel filter 8 can be installed before the liquid transfer pump 9 to form a two-stage filtration mechanism for the liquid at the front end of the pump. On the one hand, this can minimize the impact of pipeline blockage, and on the other hand, it can effectively protect the liquid transfer pump 9 and prevent debris from causing abnormal operation of the liquid transfer pump 9.

[0025] Furthermore, the monitoring system also includes a second three-way valve 4, which is connected to the feeding pipeline, the field equipment 11, and the discharge pipeline (arrow in the figure). The second three-way valve allows the liquid material to enter the field equipment during normal feeding, and can be discharged directly after cleaning without entering the field equipment 11 for storage.

[0026] Finally, it can be added that, in order to effectively prevent and promptly handle pipeline blockages, the monitoring system may also include an audible and visual alarm device. The audible and visual alarm device is associated with the electrical signals of the first electromagnetic flowmeter and the second electromagnetic flowmeter. For example, when the flow value is abnormal, it can output an audible and visual alarm immediately to remind personnel to handle the situation as soon as possible.

[0027] In summary, the main design concept of this utility model lies in reliably detecting conveyor blockages during the material dispensing process and clearing them using a water-washing and air-blowing method, thereby ensuring that the spice kitchen can quickly send the liquid material to the production site storage tanks for production. Specifically, a first solenoid valve connected to the cleaning water source and a second solenoid valve connected to the compressed air source are connected to the front end of the dispensing pipeline via a first three-way valve. A first electromagnetic flow meter and a second electromagnetic flow meter are installed before and after the liquid delivery pump in the dispensing pipeline, respectively. The first electromagnetic flow meter is used to detect blockages in the dispensing pipeline between the liquid storage tank and the liquid delivery pump, and the second electromagnetic flow meter is used to detect blockages in the dispensing pipeline between the liquid delivery pump and the field equipment. This utility model effectively avoids filter and pipeline blockages, ensuring stable dispensing flow control and product quality while reliably reducing equipment damage rates and preventing contamination and loss of liquid material due to equipment maintenance.
