Explosion-Proof 200L Drum Filling Machine for Chemical Liquids

The 200L full-automatic self-loading and filling machine is an efficient, precise, and large-scale liquid filling equipment. Below is a detailed introduction to it:

Basic Components

Feeding System:

• Liquid Storage Tank: Usually made of stainless steel such as common 304 or 316 stainless steel to ensure the safety and corrosion resistance of the stored liquid. Its capacity is generally 200L, which can meet the production needs of a certain scale.
• Transfer Pump: Responsible for transporting the liquid in the storage tank to the filling position. Generally, corrosion-resistant, stable flow, and suitable lift centrifugal pumps or gear pumps are selected.

Filling System:

• Filling Head: It is the key component that directly contacts the container for liquid filling. It is usually equipped with a high-precision flowmeter and control valve to ensure the accuracy and stability of the filling volume. In order to meet the characteristics of different liquids and filling needs, there will be anti-drip designs such as anti-drip pipes or special valve core structures.
• Metering Device: There are two common types, flowmeters and weighing sensors. The flowmeter determines the filling volume by measuring the volume of the liquid, while the weighing sensor determines the filling volume by measuring the weight of the liquid, which is more suitable for liquids with high viscosity or extremely high filling accuracy requirements.

Container Conveying System:

• Conveying Belt: Used to convey empty containers and filled containers to the corresponding positions. It is usually made of wear-resistant and corrosion-resistant materials such as rubber or plastic. The speed can be adjusted according to actual production needs to ensure synchronous operation with the filling system.
• Positioning Device: There will be positioning devices on the conveying belt, which can accurately and effectively prevent the container from shifting or moving during the filling process, ensuring the accuracy of filling.

Control System:

• PLC Programmable Controller: As the core control component of the entire filling machine, it is responsible for receiving and processing signals from various sensors, and precisely controlling the actions of each actuator according to preset programs. It has the advantages of high reliability, strong anti-interference ability, and flexible programming. It can carry out personalized program writing and adjustment according to different production needs.
• Touch Screen Man-Machine Interface: Operators can conveniently set various parameters such as filling volume, filling speed, and equipment start-stop through the touch screen, and can also monitor the operating status and fault information of the equipment in real time, making the operation more intuitive and convenient, and greatly improving the operability and intelligence level of the equipment.

Sealing System:

• Capping Machine: For some containers that need to be sealed, the capping machine can accurately place the cap on the container and press it tightly through a robotic arm or rotating mechanism to perform a pressing or screwing operation, ensuring good sealing of the container.
• Cap Pressing Device: Some equipment is also equipped with a special cap pressing device. For some containers that need to be pressurized and sealed (such as flammable and explosive liquids), pressure is applied to the cap through a hydraulic or pneumatic system to make it closely fitted with the container and prevent liquid leakage.

Coding System:

The coding machine can automatically print production dates, batch numbers, product models, etc. on the surface of the container, facilitating product traceability and management.

Working Principle

Preparation Work: Before starting the filling machine, it is necessary to carefully check whether all components are normal, and ensure that the feeding system, filling system, conveying system, and control system are all in a ready state. At the same time, prepare a sufficient number of empty containers and place them neatly in the specified position.

Conveying and Positioning: After starting the conveying system, the empty containers will be smoothly conveyed to the filling position through the conveying belt. The positioning device will automatically position the containers to make them in the best filling state.

Peeling and Filling: When the filling signal is sent, the liquid in the feeding system will flow into the metering device of the filling head under the action of the transfer pump. Before starting to fill, the metering device will automatically perform a peeling operation, that is, deduct the weight of the container itself, so as to ensure the accuracy of the filling volume.

Sealing and Coding: After the filling is completed, the conveying system will convey the filled containers to the sealing position for sealing operations. Then, the coding machine will automatically print relevant information on the surface of the container.

Finished Product Output: After sealing and coding, the containers will be conveyed by the conveying system to the finished product area again, waiting for further processing or transportation.

Performance Characteristics

• High Efficiency and High Yield: It can quickly and continuously complete the filling work of large-batch liquids, significantly improving production efficiency and reducing labor costs. According to different specific models and configurations, the number of barrels filled per minute can range from several to tens.
• High Precision: Using advanced metering technology and control systems, it can ensure that the filling volume error of each container is controlled within a very small range. For example, the filling accuracy of some equipment can reach ±20L (for 20L) and ±100L (for 200L), thus ensuring the stability of product quality.
• Strong Adaptability: It can flexibly adjust the filling parameters and process flow according to different liquid characteristics and production needs, and is suitable for filling liquids with various viscosities and corrosiveness, having strong universality and flexibility.
• Safety and Reliability: It has multiple safety protection measures such as overload protection, leakage protection, explosion-proof design (for flammable and explosive liquids), etc., which can effectively protect the personal safety of operators and the stable operation of equipment, reducing the accident rate.
• Easy Maintenance: The overall structure design is reasonable, and each component is easy to disassemble and install. Daily cleaning, maintenance, and repair work are convenient and quick, which can reduce equipment downtime and lower long-term use costs.

Technical Parameters

• Filling Capacity: Usually 200L, but it may vary according to specific models and configurations.
• Filling Accuracy: High-precision weighing or flow measurement, and the filling accuracy of some equipment can reach ±20L (20L) and ±100L (200L).
• Filling Speed: The speed is continuously adjustable, generally ranging from several barrels to tens of barrels per minute.
• Power Requirements: According to different specific models and configurations, generally AC220V/50Hz or AC380V 50Hz ± 2Hz.
• Air Source Requirements: Some equipment is connected to an external air source, and the air pressure is usually between 0.4-0.8MPa.

Application Fields

• Chemical Industry: It can be used for filling various chemical raw materials, chemicals, resins, coatings, lubricating oils, and other liquid materials.
• Food and Beverage Industry: Suitable for filling food and beverages such as juice beverages, mineral water, edible oils, and medicinal liquids.
• Daily Chemical Industry: Used for filling daily chemical products such as detergents, skin care products, cosmetics, etc.
• Pharmaceutical Industry: Some equipment complies with GMP standards and can be used for filling medicines, injections, and other pharmaceuticals.

In general, the 200L full-automatic self-loading and filling machine has become one of the indispensable important equipment in modern industrial production due to its efficient production capacity, precise filling control, and wide application range.
