Abstract
Description
Technical Field
[0001] This utility model relates to the field of cigarette equipment technology, and in particular to a loose heating water tank. Background Technology
[0002] In the tobacco processing industry, the loosening process on the tobacco forming line is one of the crucial steps to ensure that the tobacco material reaches its optimal physical state. To increase the process water temperature and promote moisture absorption by the tobacco material, a heated water tank is typically installed in the loosening process. This tank is used to heat tap water to approximately 74°C.
[0003] However, during use, tap water contains a high concentration of hardness ions (such as calcium and magnesium). When the water is heated, these ions easily form insoluble carbonate or sulfate precipitates, known as limescale. Over time, limescale gradually accumulates on the inner wall of the heating tank, the outlet pipes, and the filter screen, causing narrowing or even blockage of the pipes, thus affecting the equipment's efficiency and potentially causing adverse effects on the production process.
[0004] In the domestic market, existing heating water tank designs are insufficient to meet the demands for efficient cleaning. On the one hand, traditional cleaning methods are time-consuming and labor-intensive, and cannot completely remove scale; on the other hand, frequent manual cleaning increases maintenance costs and may damage the equipment.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0043] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0044] See Figure 1 The present application provides a loosely heated water tank, including a tank body 1;
[0045] The water inlet assembly is connected to the water inlet of the water tank 1 and controls the liquid depth inside the water tank 1; the heating assembly controls the liquid temperature inside the water tank 1; the drain assembly is connected to the water outlet of the water tank 1 and is used to transport the heated liquid inside the water tank 1 to the nozzle pipe 2; the cleaning assembly is connected to the drain assembly at one end and to the water tank 1 at the other end and is used to clean the water tank 1 and the drain assembly.
[0046] Preferably, the water tank body 1 has sufficient capacity to meet the water demand during tobacco processing, and the tank body material is selected as stainless steel with excellent corrosion resistance and thermal conductivity to ensure long-term stable operation in high-temperature environments.
[0047] The water inlet assembly is connected to the water inlet of the water tank 1. Its function is to precisely control the flow rate of tap water entering the water tank 1, thereby adjusting the depth of the liquid in the water tank 1 and ensuring a stable water level.
[0048] The heating element is installed inside the water tank 1 and is responsible for heating the tap water to about 74°C to facilitate the absorption of moisture by the tobacco material in subsequent processes.
[0049] The drainage assembly is connected to the outlet of the water tank 1 via a pipe. Its function is to efficiently deliver the heated liquid to the nozzle pipeline for direct application to the tobacco material. To prevent stress damage caused by temperature changes, the drainage assembly should use a flexible connection to ensure the reliability of the system.
[0050] The cleaning component is connected to the drainage component at one end and to the water tank 1 at the other end, forming a closed loop system. When cleaning is required, chemical agents are introduced into the water tank 1 to thoroughly flush the entire water tank 1 and the inside of the drainage component, effectively removing any scale that may form, reducing maintenance frequency, and extending the service life of the equipment.
[0051] Based on the above embodiments, the drainage assembly includes a first filter 3, which is connected to the first outlet of the water tank 1 through a drainage pipe; a second filter 4, which is connected to the second outlet of the water tank 1 through a drainage pipe; a gear pump 5, the outlets of the first filter 3 and the second filter 4 are both connected to the inlet of the gear pump 5; a flow meter 6, which is connected to the outlet of the gear pump 5, and the outlet of the flow meter 6 is connected to the nozzle pipeline 2. A control valve (not shown in the attached figure) is provided on the nozzle pipeline 2, and the flow meter 6 and the gear pump 5 uniform control module establish a signal connection.
[0052] Specifically, the first filter 3 is connected to the first outlet of the water tank 1 through a drainage pipe, and the second filter 4 is connected to the second outlet of the water tank 1 through another drainage pipe. They are used to filter the liquid flowing out of the water tank 1, remove larger particles of impurities, and protect downstream equipment from damage.
[0053] The outlets of both the first filter 3 and the second filter 4 are connected to the inlet of the gear pump 5. The function of the gear pump 5 is to provide sufficient pressure so that the filtered liquid can be stably and evenly delivered to the next stage. The gear pump 5 has good corrosion resistance and wear resistance, making it suitable for long-term operation in high-temperature environments.
[0054] Flow meter 6 is connected to the outlet of gear pump 5 to accurately measure and monitor the liquid flow rate through the system. The outlet of flow meter 6 is directly connected to nozzle pipeline 2 to ensure that the liquid can reach the application point accurately. In addition, a control valve (not shown in the attached diagram) is installed on the nozzle pipeline to control the opening and closing of nozzle pipeline 2.
[0055] Both the flow meter 6 and the gear pump 5 establish signal connections with the control module. The control module can not only receive data feedback from the flow meter 6, but also send commands to the gear pump 5.
[0056] Based on the above embodiments, a first shut-off valve 7 and a second shut-off valve 8 are also included. The first shut-off valve 7 is disposed on the drainage pipe between the first filter 3 and the water tank body 1, and the second shut-off valve 8 is disposed on the drainage pipe between the second filter 4 and the water tank body 1. In other words, the addition of the first shut-off valve 7 and the second shut-off valve 8, which are respectively disposed on the drainage pipe between the first filter 3 and the second filter 4 and the water tank body 1, realizes independent control of the drainage pipe.
[0057] Based on the above embodiments, the cleaning component includes a three-way connector, the first end of which is connected to the nozzle pipe 2 located between the control valve and the flow meter 6; a cleaning return pipe 9, one end of which is connected to the second end of the three-way connector and the other end of which is connected to the water tank 1, and a third shut-off valve 10 is provided on the cleaning return pipe 9; and a sewage pipe 11, which is connected to the third end of the three-way connector, and a fourth shut-off valve 12 is provided on the sewage pipe 11.
[0058] Specifically, one end of the cleaning return pipe 9 is connected to the second end of the tee connector, and the other end is connected to the water tank body 1, forming a return path for the cleaning liquid. A third shut-off valve 10 is installed on the cleaning return pipe 9 to control the return of the cleaning liquid. When cleaning is performed, the third shut-off valve 10 can be opened to allow the cleaning liquid to flow back from the nozzle pipe 2 to the water tank body 1 for internal cleaning.
[0059] The sewage pipe 11 is connected to the third end of the tee connector and is used to discharge sewage and impurities generated during the cleaning process. A fourth shut-off valve 12 is installed on the sewage pipe 11 to control the sewage discharge process. When sewage needs to be discharged, the fourth shut-off valve 12 can be opened to allow the sewage to be discharged through the sewage pipe 11.
[0060] Workflow:
[0061] Before performing the cleaning operation, first ensure that the water inlet component and the heating component are both in a stopped state; at the same time, close the control valve on nozzle line 2.
[0062] Inject an appropriate amount of chemical agent into the water tank 1. The chemical agent should have good descaling ability and be able to effectively remove scale from the inside of the water tank, filter and flow meter. When injecting the chemical agent, ensure that the amount and concentration of the agent meet the cleaning requirements to avoid damage to the equipment.
[0063] Open the third shut-off valve 10, close the fourth shut-off valve 12, and start the gear pump 5. The chemical agent enters along the drain pipe under the action of the gear pump 5, and returns to the water tank 1 along the cleaning return pipe 9 through the pressurization action of the gear pump, forming a closed cleaning cycle.
[0064] During the process, the chemical agents will fully contact and rinse the inside of the water tank body 1, the first filter 3, the second filter 4 and the flow meter 6 to remove the attached scale.
[0065] After the cleaning cycle has been running for a period of time, the third shut-off valve 10 is closed and the fourth shut-off valve 12 is opened to allow the waste liquid to be discharged through the drain pipe 11.
[0066] After cleaning, close the third shut-off valve 10 and the fourth shut-off valve 12, and open the control valve on the nozzle pipeline 2 to restore the system to normal operation.
[0067] Based on the above embodiments, the water inlet assembly includes a water inlet pipe 13 connected to the water inlet of the water tank 1; a solenoid valve 14 disposed on the water inlet pipe 13; a solenoid valve controller 15 electrically connected to the solenoid valve 14; and a liquid level sensor 16 disposed inside the water tank 1, which is electrically connected to the solenoid valve controller 15.
[0068] Specifically, when the liquid level in the water tank 1 is lower than the preset value, the liquid level sensor 16 transmits a signal to the solenoid valve controller 15. After receiving the signal, the solenoid valve controller 15 opens the solenoid valve 14, and the water inlet pipe continuously supplies water to the water tank 1 until the preset water inlet time is reached. When the preset water inlet time is reached, the solenoid valve controller 15 controls the solenoid valve 14 to close and stop supplying water to the water tank 1.
[0069] Based on the above embodiments, a water filter 17 is also provided on the water inlet pipe 13, and the water filter 17 is located closer to the inlet of the water inlet pipe 13 than the solenoid valve 14.
[0070] Specifically, the water filter 17 is installed on the water inlet pipe 13, which is closer to the inlet of the water inlet pipe 13 than the solenoid valve 14. The water filter 17 uses high-efficiency filter material and has excellent filtration performance. It can remove suspended solids and particulate matter in the water and ensure that the water entering the water tank meets the requirements.
[0071] Based on the above embodiments, the heating assembly includes a steam pipe 18 connected to the steam inlet of the water tank 1; a pneumatic diaphragm valve 19 disposed on the steam pipe 18; a pneumatic diaphragm valve controller 20 electrically connected to the pneumatic diaphragm valve 19; and a temperature sensor 21 disposed inside the water tank 1, which is electrically connected to the pneumatic diaphragm valve controller 20.
[0072] In other words, temperature sensor 21 continuously monitors the water temperature in the tank and feeds the data back to pneumatic diaphragm valve controller 20. When the water temperature falls below the set lower limit, temperature sensor 21 triggers pneumatic diaphragm valve controller 20, causing it to send an open signal to pneumatic diaphragm valve 19, allowing steam to enter the water tank 1 through steam pipe 18. As the water temperature rises to the set upper limit, temperature sensor 21 triggers pneumatic diaphragm valve controller 20 again, sending a close signal to pneumatic diaphragm valve 19 to stop the steam supply.
[0073] Based on the above embodiments, a steam nozzle 22 is provided inside the water tank body 1. The steam nozzle 22 is connected to the steam pipe 18 and has multiple steam injection holes.
[0074] In other words, the steam nozzle 22 is equipped with multiple steam injection holes. The uniform distribution of these multiple steam injection holes enables uniform heating of steam within the water tank 1, thereby improving heating efficiency and water temperature uniformity.
[0075] Based on the above embodiments, a steam filter 23 is also provided on the steam pipe 18, and the steam filter 23 is positioned closer to the inlet of the steam pipe 18 than the pneumatic diaphragm valve 19.
[0076] In other words, the steam filter 23 is installed on the steam pipe 18, closer to the inlet of the steam pipe 18 than the pneumatic diaphragm valve 19. The steam filter 23 uses high-efficiency filter material, which has excellent filtration performance and can remove suspended solids, particulate matter and contaminants from the steam, ensuring the quality of the steam entering the water tank.
[0077] Based on the above embodiment, the bottom of the water tank body 1 is installed on the ground by a bracket 24.
[0078] In other words, bracket 24 is used to support and fix the bottom of the water tank body 1. Bracket 24 is made of high-strength material and has sufficient load-bearing capacity and stability to ensure the stability and safety of the water tank body 1 after installation.
[0079] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.
[0080] This article uses specific examples to illustrate the principles and implementation methods of this utility model.

It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principles of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
