Description

Technical Field

[0001] This invention relates to a chemical filling apparatus, and more particularly to a clean filling apparatus for barrelled chemicals. Background Technology

[0002] In industries such as chemicals, food, and pharmaceuticals, the filling of bottled liquid materials is one of the core production processes. Currently, most widely used bottled filling equipment employs an open-structure design, meaning that key workstations such as the filling head, conveyor line, and bottle positioning area are directly exposed to the operating environment. While this design facilitates manual intervention and equipment maintenance, its inherent open architecture leads to several problems. For example, moving parts such as lifting mechanisms, conveyor chains, and rotating platforms during the filling process are not completely enclosed. This open structure easily causes risks of mechanical pinching, liquid splashing and scattering, bottle displacement and tipping, and the diffusion of volatile substances, posing significant safety hazards. Furthermore, the filling port is directly connected to the air, allowing suspended particles and microorganisms from the environment to enter the bottle with the airflow. This can cause contamination of strictly controlled electronic chemicals and makes it difficult to guarantee the cleanliness of the filling environment, severely restricting production safety and product quality. Summary of the Invention

[0003] In view of this, the purpose of this application is to provide a clean filling device for drummed chemicals, which can solve the safety risks of existing open filling, and at the same time, the device improves the cleanliness of the filling environment.

[0004] To achieve the above-mentioned technical objectives, this application provides a clean filling device for drummed chemicals, which mainly includes a filling chamber set in the main body of the device. The filling chamber is equipped with a feeding system, a clean filtration system, an exhaust gas treatment system, and a ton container. The feeding system is set on one side of the filling chamber. One end of the feeding system is connected to the material pipe outside the filling device, and the other end is connected to the ton container opening inside the filling chamber. The top of the filling chamber is equipped with a clean filtration system and an exhaust gas treatment system.

[0005] Furthermore, a roller shutter door is provided on one side of the filling chamber.

[0006] Furthermore, a sealed transfer device is provided at the opening of the ton container. The sealed transfer device includes a liquid collection tray, a liquid phase pipe, and a gas phase pipe.

A clean filtration system and an exhaust gas treatment system are respectively installed on the top of the filling chamber.

[0023] like Figure 1 , Figure 2As shown, the ton container opening (4) is equipped with a sealed transfer device, which includes a liquid collection tray (8), a liquid phase pipe (11) and a gas phase pipe (12). The liquid collection tray (8) is surrounded by a barrier, which enables the structure to have a containment function. The liquid phase material remaining in the liquid collection tray (8) can be recycled and treated as waste liquid. The liquid phase pipe (11) and the gas phase pipe (12) are vertically installed in the middle of the liquid collection tray (8). The liquid phase pipe and the gas phase pipe are fixedly connected to the liquid collection tray. The connection method can be conventional welding or integral molding, etc. The upper part of the liquid phase pipe (11) and the gas phase pipe (12) that protrudes from the liquid collection tray is provided with external threads. The bottom of the liquid collection tray extends out of the internal threaded sleeve, which is connected to the ton container opening.

[0024] In some embodiments, the length of the liquid phase tube (11) is greater than that of the gas phase tube (12), and the depth of the liquid phase tube (11) extending into the ton is greater than that of the gas phase tube (12), which can prevent material splashing and is more conducive to the absorption of tail gas from the gas phase tube.

[0025] In some embodiments, the feeding system includes a feed pipe (2), a feed valve (3) and a sealed adapter. One end of the feed pipe (2) is connected to the material pipe outside the filling device, and the other end of the feed pipe (2) is connected to the liquid phase pipe (11) on the sealed adapter through a liquid phase connector sleeve (9) with internal threads.

[0026] In some embodiments, the exhaust gas treatment system includes an exhaust pipe (6), a suction hood hand valve (5.1), and a suction hood (7). The upper end of the exhaust pipe (6) is connected to an external ventilation device, and the lower end of the exhaust pipe (6) is provided with a suction hood hand valve (5.1) and a suction hood (7) in sequence.

[0027] In some embodiments, an exhaust branch pipe (13) is provided on the exhaust pipe (6), and a gas phase pipe hand valve (5.2) is provided on the exhaust branch pipe (13). The lower end of the exhaust branch pipe (13) is connected to the gas phase pipe (12) on the sealed adapter through a gas phase connector sleeve (10) with internal threads.

[0028] In some embodiments, the clean filtration system includes a high-efficiency filter and an FFU (Fan-Full Unit) induced draft fan located at the top of the filling chamber. The FFU induced draft fan is located outside the filling chamber, and the outlet of the induced draft fan is equipped with a high-efficiency filter. The outlet of the high-efficiency filter is located at the top of the filling chamber.

[0029] In some embodiments, the filling material of the high-efficiency filter includes any one of glass fiber, fluoropolymer composite filter bag, activated carbon particles, and ceramic filter element. In this embodiment, the high-efficiency filter is preferably filled with glass fiber filter material, and the more specific Nokel FB high-efficiency filter on the market can be selected.

[0030] In some implementations, a weight monitoring platform (14) is provided at the bottom of the ton container. The weight monitoring platform is connected to a WICA weight measurement and control sensor (15) to provide real-time feedback of filling weight data. WICA usually refers to a weight measurement and control system in the field of industrial automation. It is mainly used to monitor and control the weight of materials in real time. It is commonly used in chemical production, automated warehousing and other scenarios. The weight of materials is detected in real time by a weighing sensor. When the preset value is reached, control commands are automatically triggered (such as zeroing the weight, stopping feeding, adjusting the conveying speed, etc.).

[0031] The working process of this utility model:

[0032] Cleaning process: After the target clean environment is achieved by replacing the fresh air with clean air through the FFU blower and the high-efficiency filter, the empty ton (4) is placed on the weight monitoring platform (14) to wait for feeding; the original lid of the empty ton is unscrewed, the suction hood (7) is moved to the vicinity of the lid area of ​​the empty ton (4), and the suction hood hand valve (5.1) is opened to draw air, so that the surrounding environment of filling is clean, and at the same time, the residual material in the barrel is prevented from evaporating into the filling room.

[0033] Filling pipe connection: Connect the sealed adapter to the ton (4) by means of internal and external thread connection. Connect the gas phase connector sleeve (10) at the end of the exhaust branch pipe to the gas phase pipe (12) outlet of the sealed adapter by means of thread connection. Open and adjust the valve opening of the gas phase pipe hand valve (5.2) on the exhaust branch pipe and evacuate the ton (4). Then connect the liquid phase connector sleeve (9) at the end of the feed pipe to the liquid phase pipe (11) on the sealed adapter by means of thread connection. After the connection is completed, close the suction hood hand valve (5.1) and move the suction hood (4) outside the ton.

[0034] Feeding: By setting a weight monitoring platform (14) at the bottom of the ton barrel, the weight monitoring platform is connected to the WICA weight measurement and control sensor (15) to clear the weight data of the ton barrel (2), and the material feeding valve (3) is automatically opened by the PLC system; the liquid material enters the material feeding valve (3), liquid phase connector sleeve (9), liquid phase pipe (11) and ton barrel (4) in sequence through the pipeline. After the value of the WICA weight measurement and control sensor reaches the set value, the PLC system automatically closes the material feeding valve (3).

[0035] The process of exhausting gas inside the barrel is as follows: material volatilization → gas rises inside the barrel → through the upper gas phase pipe (12) → gas phase connector sleeve (10) → exhaust branch pipe (13) → gas phase pipe hand valve (5.2) → external tail gas system of the device.

[0036] Removal of filling pipeline: After the material inlet valve (3) is closed and all the material in the valve flows into the ton (4), close the gas phase pipe hand valve (5.2) to stop the evacuation of the ton; pull the suction hood (7) to the vicinity of the liquid collection tray (8) and open the suction hood hand valve (5.1) to evacuate; disconnect the liquid phase connector sleeve (9) of the material inlet and collect the remaining small amount of liquid phase material in the liquid phase connector sleeve (9) into the liquid collection tray (8); the volatilized gas phase is evacuated through the suction hood (7); disconnect the gas phase connector sleeve (10) and collect the remaining tail gas in the gas phase connector sleeve (10) and part of the exhaust branch pipe (13) into the liquid phase material after condensation into the liquid collection tray (8); the volatilized gas phase is evacuated through the suction hood (7).

[0037] Ton container removal: Disconnect the sealed adapter from the ton container (2); then seal the ton container with the original lid; collect the liquid material remaining on the collection tray (8) above the sealed adapter for unified waste liquid recycling; finally close the suction hood hand valve (5.1) and move the ton container (4) filled with material outside the clean area.
