The fully automatic pneumatic sample delivery system uses compressed air (high-pressure fan) with a certain pressure introduced into the conveying pipeline to generate airflow thrust (or suction) to push the sample box containing the sample, achieving the purpose of transporting the sample.
When the system is working, the prepared samples are placed in the workshop sending end receiving and transmitting device, and the boxes are automatically closed inside the workshop sending end receiving and transmitting device. The sample boxes containing the samples are transported to the laboratory receiving end receiving and transmitting device using the thrust (or suction) of pressurized gas. The interior of the laboratory receiving and transmitting device is opened, and the samples fall into the receiving box or to the designated workstation, which facilitates the later use of robotic hands to grab the samples for analysis and testing. The empty sample box automatically returns to the receiving and sending device in the workshop and enters the next cycle.
According to the different on-site gas supply conditions of the user, positive pressure or positive and negative pressure conveying processes can be used; According to the different characteristics and appearance dimensions of the samples, corresponding fully automatic pneumatic sample delivery systems can be designed.
The fully automatic pneumatic sample delivery system of Jinan Haiying Electromechanical has the following characteristics:
1. All day operation, stable, fast, and accurate sample delivery speed:
The pneumatic sample delivery method, which places the sample in a specially designed container and transports it through a closed pipeline, is not affected by environmental and climatic conditions and can operate 24/7. The sample delivery speed is about 10-30m/s, which is fast, efficient, safe and reliable. It can effectively reduce human intervention, lower labor costs, and improve the level of equipment intelligence.
2. High degree of automation:
Efforts should be made to improve the degree of automation, reduce the labor intensity of workers, improve operating conditions, attach importance to safety, hygiene, and labor protection in the production process, ensure the safety of enterprise production, and guarantee the health of workers.
Both the workshop sending end and the physical and chemical room receiving end can realize the functions of opening, closing, and detecting inside the cabinet. The workshop sending end can be conveyed with one click, and the physical and chemical room receiving end does not require manual intervention. According to actual needs, the operation mode can switch between manual, semi-automatic, and fully automatic modes.
3. The receiving cabinet is equipped with high-efficiency filters and super strong buffering soft landing:
Efficient filter: In order to solve the difficulty of internal valve leakage or damage to the valve core due to high impurities in the compressed air source or air source pipeline in the sending and receiving cabinet, an efficient filter is built into the cabinet. The filter element is made of stainless steel material, and the conveying air source is filtered by the efficient filter, which can effectively extend the maintenance cycle.
Super strong buffering soft landing: In order to reduce the impact of the sample box on the internal components of the receiving and transmitting cabinet during high-speed operation and descent, a multi pronged approach is adopted to achieve early deceleration of the sample box in the external pipeline, lifting and lowering of the sample box with a back blowing air source during descent, and soft cushion landing at the terminal, achieving smooth reception of the sample box.
4. Efficient cold drawn conveying pipes and fine construction with multiple measures taken simultaneously
The sample box runs at high speed in the conveying pipeline, and the quality and construction level of the conveying pipeline seriously affect the stable operation of the pneumatic sample delivery system. The conveying pipeline of this project adopts the company's specially designed seamless pipe, which adds multiple cold drawing processes on the basis of conventional pipes, reducing internal roughness, improving smoothness, and reducing roundness deviation. The internal groove of the pipeline is processed, and a dedicated sleeve is used for pipeline docking, which effectively ensures sealing and coaxiality. The combination of specialized cold drawn tubes and professional construction techniques ensures the high efficiency and stability of the pneumatic sample delivery system.
5. Data transmission system
The pneumatic sample delivery system is equipped with a control system that can receive sample ID information from the production management system. The sample ID information can be read according to the format requirements of Party A, and the received plan data (sample ID information) can be automatically identified and distributed to the corresponding stations for selection when sending samples on site; Each set of wind turbines is completely independent in electrical control, but can also backup each other in data transmission. It can automatically generate sample number sending time, arrival time, running time, sample information, etc., and can store all data and generate table downloads. It can comprehensively display the layout, equipment operation status, real-time sample tracking, and fault recording functions of all pneumatic sample delivery systems, and can be uploaded to the Party A's big data platform or on-site industrial screen.
