[0002] Precious metal inorganic salt solutions are mainly used in automotive exhaust treatment catalysts and are key raw materials. The raw material ratios are extremely strict during catalyst production. High precious metal content gives the product high value, thus requiring efficient and accurate product packaging. Currently, some precious metal solution packaging devices are highly automated, but require significant investment and are suitable for large-volume, continuous product packaging, but not for small-volume, intermittent product packaging. The high investment also puts pressure on small and medium-sized enterprises. Other packaging devices are too primitive, requiring more manual intervention, and are cumbersome, inefficient, and prone to errors, making it difficult to meet the requirements for accurate, efficient, and simple packaging processes. Utility Model Content

[0003] To overcome the problem that existing devices for dispensing precious metal solutions cannot balance efficiency and practicality, this invention provides a filling device for liquid dispensing.

[0004] The technical solution adopted by this utility model to solve its technical problem is: A filling device for liquid dispensing includes a dispensing tank with an inlet and an outlet at the top and an outlet at the bottom.

Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings.

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0019] like Figure 1 As shown, this utility model provides a filling device for liquid dispensing.

[0020] A filling device for liquid dispensing includes a dispensing tank 12, which has a liquid inlet and an air outlet at the top and a liquid outlet at the bottom.

[0021] The dispensing tank 12 has an outward-facing inlet pipe for drawing liquid from the storage tank 9. An automatic valve 8 is installed on the inlet pipe. The dispensing tank 12 also has an outward-facing outlet pipe connected to a vacuum line and equipped with an automatic valve 2. When the automatic valves 2 and 8 are opened, liquid enters the dispensing tank 12 from the storage tank 9 under negative pressure.

[0022] It is also equipped with an electronic scale 25 and a central control panel 26. The electronic scale 25 and the central control panel 26 are connected by signals and are used to measure the amount of liquid contained in the packaging bottle 22 on the electronic scale 25. The liquid outlet on the dispensing tank 12 is provided with a liquid outlet pipeline to deliver liquid into the packaging bottle 22. An automatic valve is configured on the liquid outlet pipeline to control the opening and closing of the liquid outlet pipeline.

[0023] In this application, the liquid is drawn into the dispensing tank 12 under negative pressure through the above settings, and the packaging box on the electronic scale 25 of the dispensing tank 12 is measured. The structure is simple, the cost is low, and it can be used for automatic filling, which is efficient and simple.

[0024] In practice, the storage tank 9 is a mobile device that needs to be moved at any time. After each batch of products is produced, the product liquid storage tank 9 needs to be moved to the vicinity of the production equipment, and the product liquid in the production equipment needs to be moved into the storage tank 9.

[0025] Reference Figure 1 As shown, valve 6 is installed on the inlet pipeline to control the entire inlet pipeline. In parallel with the aforementioned automatic valve 8, valve 7 is also provided as an alternative branch line for use in special circumstances, such as maintenance. In this embodiment, valves 6 and 7 are implemented as manual ball valves.

[0026] In practice, the central control console 26 can automatically zero the electronic scale 25. After the operator places the packaging bottle 22 onto the electronic scale 25, the central control console 26 extracts the tare weight data and then zeros it. Furthermore, upper and lower limits can be set within the central control console 26 for the tare weight data of the packaging bottle 22, so that when the tare weight data of the packaging bottle 22 is abnormal, the system alarms and the automatic filling enters a temporary stop state.

[0027] In this embodiment, automatic valve 2 is a three-way valve capable of switching between vacuum and exhaust, and features automatic control. Automatic valve 2 is connected to both the vacuum line and the exhaust duct. Valve 3 is installed on the duct connecting automatic valve 2 to the vacuum line to control vacuum opening and closing; valve 1 is installed on the duct connecting automatic valve 2 to the exhaust duct to control the exhaust switch. Specifically, valves 1 and 3 are manual ball valves.

[0028] In this embodiment, a liquid level controller 4 is installed inside the dispensing tank 12. Automatic valve 2 and automatic valve 8 are both connected to the liquid level controller 4, so that when the liquid level in the dispensing tank 12 reaches a certain level, the liquid will no longer enter the dispensing tank 12 from the storage tank 9.

[0029] In this embodiment, a liquid level alarm 5 is installed inside the dispensing tank 12. The liquid level alarm 5 is connected to an alarm device, so that when the liquid level in the dispensing tank 12 reaches a certain level, the alarm device will issue a warning.

[0030] The alarm device is an existing external device that can emit a sound or activate a flashing light to provide a warning effect, which will not be described in detail here.

[0031] In this embodiment, the liquid level monitored by the liquid level alarm 5 is higher than the liquid level monitored by the liquid level controller 4.

[0032] Preferably, the dispensing tank 12 is configured as a transparent high-level trough made of PVC.

[0033] In this embodiment, the dispensing tank 12 is positioned higher than the electronic scale 25, so that the liquid can enter the packaging bottle 22 on the electronic scale 25 under the action of gravity from the dispensing tank 12.

[0034] Using the above method, the liquid is transferred to the dispensing tank 12 using a vacuum, and then lowered by gravity. This avoids the use of power equipment and facilitates precise metering control.

[0035] Reference Figure 1 As shown, the dispensing tank 12 is placed on the workbench, and the electronic scale 25 and the packaging bottle 22 on it are located below the liquid outlet on the dispensing tank 12.

[0036] In this embodiment, a leakage detection device is included, which includes a drip tray and a leakage detection sensor disposed at the bottom of the drip tray. The drip tray is disposed at the bottom of the dispensing tank 12 or on the electronic scale 25.

[0037] Specifically, refer to Figure 1 The dispensing tank 12 is placed on the first drip tray 14, and a first leak detection sensor 13 is installed at the bottom of the first drip tray 14 to detect whether the dispensing tank 12 is leaking. A second drip tray 24 is placed on the electronic scale 25, and a second leak detection sensor 23 is installed at the bottom of the second drip tray 24. In practice, the packaging bottle 22 is placed on the second drip tray 24 to detect whether the packaging bottle 22 is leaking. The presence of the drip tray can also prevent the workbench, electronic scale 25, and other surfaces from being corroded.

[0038] In practice, the placement position of the packaging bottle 22 can be marked on the second liquid receiving tray 24 to facilitate the rapid positioning of the packaging bottle 22.

[0039] In this embodiment, a hose receiving cylinder 10 is also included. The upper end of the hose receiving cylinder 10 is open, and the lower end has an outlet. A valve is provided at the outlet, namely valve 11 in the figure. The hose receiving cylinder 10 is used to house the end of the inlet pipe or the end of the outlet pipe. In this embodiment, valve 11 is implemented as a manual ball valve.

[0040] The hose container 10 can collect residual product liquid in the pipeline and also prevent the pipeline from being contaminated.

[0041] In this embodiment, a filter 16 is also installed on the liquid outlet pipeline. A Y-type filter 16 is used in this embodiment to effectively remove impurities that may be present in the product liquid during the filling process.

[0042] In this embodiment, the liquid outlet pipeline from the dispensing tank 12 to the packaging bottle 22 includes two parallel branches. Each branch is equipped with an automatic valve and a normally open valve. The normally open valve allows the two branches to have different flow rates, and the automatic valve adjusts the connection or closure of the two branches.

[0043] Reference Figure 1 The liquid outlet pipeline from dispensing tank 12 to packaging bottle 22 includes two branches containing automatic valves 18 and 20. Valve 19 is installed on the branch corresponding to automatic valve 18, and valve 21 is installed on the branch corresponding to automatic valve 20. Valve 19 and 21 are normally open and have different flow rates. After commissioning, they are generally not modified arbitrarily. In practice, flow rate control can be achieved using different valve models or by using different opening rates of the same valve model.

[0044] Furthermore, in this embodiment, the normally open valves on the two branch lines are needle valves to provide better control accuracy.

[0045] Reference Figure 1 A valve 15 is installed on the outlet pipeline to control the entire outlet pipeline. In parallel with the two aforementioned branch lines, a valve 17 is also provided as an alternative branch line for use in special circumstances, such as maintenance. In this embodiment, valves 15 and 17 are implemented as manual ball valves.

[0046] In practice, after the tare weight data of the packaging drum is extracted, the central control console 26 initiates the filling process. During automatic filling, valve six 15 is normally open, valve seven 17 is normally closed, and valves eight 19 and nine 21 are used to control the liquid flow rate. During the filling process, the automatic display valve three 18 automatically opens for rapid filling of the product liquid. Once the weight reaches the set value, automatic valve three 18 automatically closes, and automatic valve four 20 opens for slow filling until the set weight data is reached. Then, automatic valve four 20 automatically closes. After filling is complete, the central control console 26 extracts the weighing data from the electronic scale 25. The central control console 26 can automatically fill the extracted weight data into the product label, eliminating the need for re-entry of data and enabling rapid product label printing.

[0047] In summary, this application provides an accurate, efficient, and easy-to-operate filling device for the repackaging of precious metal salt solutions. It ensures the accuracy and efficiency of the product repackaging process, effectively prevents product leakage due to incorrect weighing, and features accurate weighing, high efficiency, simple operation, and wide application range. This device can be widely used for the repackaging of precious metal salt solutions and other similar products.

[0048] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
