Method for pneumatic sample delivery system to transport liquid samples

Abstract

The present application aims to provide a method for transmitting liquid sample by pneumatic sample delivery system, which comprises the following steps: loading the liquid sample into a reagent bottle, preventing the reagent bottle from loosening, loading the reagent bottle with the bottle cap upward into a solid sample cylinder, using the thrust of compressed air and the inertia of the sample cylinder to make the liquid sample accumulate at the bottom of the bottle, and completing the safe and leakage-free transportation of the liquid sample. In addition, a filler is added around the reagent bottle in the solid sample cylinder, which not only fixes the reagent bottle in the sample cylinder and prevents the reagent bottle from shaking, but also plays a role in shock absorption and buffering when the sample cylinder reaches the terminal of the receiving and sending cabinet, thereby protecting the reagent bottle. Based on the existing pneumatic sample delivery system, the safe and stable continuous transmission of the liquid sample is realized.

Description

Technical Field

[0001] This invention relates to the field of sample delivery technology, specifically a method for transporting liquid samples using a pneumatic sample delivery system. Background Technology

[0002] The pneumatic sample delivery system uses compressed air as power. After passing through an air tank and undergoing oil-water separation, the system is controlled by a control air circuit to propel a sample cylinder containing samples at high speed from one end to the other, rapidly delivering the sample. This achieves the purpose of transferring samples between stations, reducing the labor intensity of manual sample delivery. This system is widely used in steel and copper smelting enterprises, greatly improving the efficiency of sample transmission. However, the currently used systems are primarily designed for the rapid transmission of solid samples such as lumps or powders. The system's built-in liquid sample delivery cylinders cannot be used interchangeably or mixed with solid sample delivery cylinders. Furthermore, the operation of the liquid sample cylinder is cumbersome, and the sealing rings require frequent replacement. If not replaced promptly, it can easily contaminate the sample and cause leakage, corroding the inner wall of the pneumatic sample delivery pipeline, the air supply pipe in the pneumatic sample delivery cabinet, and electrical components, affecting stable and continuous operation. Summary of the Invention

[0003] The purpose of this invention is to provide a method for transporting liquid samples using a pneumatic sample delivery system, which, based on existing pneumatic sample delivery systems, enables safe, stable, and continuous transport of liquid samples.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is: a method for transporting liquid samples using a pneumatic sample delivery system, characterized by comprising the following steps:

[0005] A) Pour the liquid sample into the reagent bottle and tighten the cap;

[0006] B) Perform anti-loosening procedures on reagent bottles containing liquid samples;

[0007] C) Place the reagent bottle with the cap facing upwards inside the sample tube after the anti-loosening operation, and tighten the sample tube cap;

[0008] D) Place the sample tube into the receiving cabinet of the pneumatic sample delivery system for transmission.

[0009] The above-described method involves loading liquid samples into reagent bottles, securing the bottles with the liquid samples in place, and then inserting the bottles cap-up into a solid sample cylinder. The force of compressed air and the inertia of the cylinder cause the liquid samples to accumulate at the bottom of the bottles, ensuring safe and leak-free transport. Furthermore, filler material is added around the reagent bottles within the solid sample cylinder to secure them and prevent movement. This filler also acts as a shock absorber and buffer when the cylinder reaches the receiving / distributing cabinet, protecting the reagent bottles. Based on existing pneumatic sample delivery systems, this method achieves safe and stable continuous transport of liquid samples. Attached Figure Description

[0016] A method for transporting liquid samples using a pneumatic sample delivery system includes the following steps:

[0017] A) Place the liquid sample into reagent bottle 10 and tighten the cap 11;

[0018] B) Perform anti-loosening procedures on reagent bottle 10 containing liquid samples;

[0019] C) Place the reagent bottle 10 with the cap 11 facing upwards inside the sample cylinder 20 after the anti-loosening operation, and tighten the sample cylinder cap 21;

[0020] D) Place the sample tube 20 into the receiving cabinet of the pneumatic sample delivery system for transmission.

[0021] As can be seen from the above scheme, after the liquid sample is loaded into the reagent bottle 10 and the cap 11 is tightened, the reagent bottle 10 containing the liquid sample is then subjected to an anti-loosening operation to prevent the reagent bottle 10 and the cap 11 from loosening during transportation. Then, the reagent bottle 10 with the cap 11 facing upwards is placed into the solid sample cylinder 20. Utilizing the thrust of compressed air and the inertia of the conveying section, the liquid sample is made to accumulate at the bottom of the bottle, completing the safe and leak-free transportation of the liquid sample. Furthermore, filler 30 is added around the reagent bottle 10 inside the solid sample cylinder 20 to fix the reagent bottle 10 inside the sample cylinder 20, preventing the reagent bottle 10 from impacting within the sample cylinder 20, and providing shock absorption and buffering effects when it reaches the receiving and dispatching terminal.

[0022] Because this solution is used to transfer liquid samples during production control, which may involve corrosive samples, the reagent bottles selected for this solution are made of HDPE material, which has good corrosion resistance and impact resistance. Preferably, reagent bottle 10 is a wide-mouth reagent bottle, which is more conducive to the pouring and collection of liquids, and the volume of reagent bottle 10 is smaller than the cavity of sample cylinder 20, so it must be ensured that the sample cylinder cap 21 can be completely closed.

[0023] like Figure 2 As shown, in step B), the reagent bottle 10 containing the liquid sample is wrapped with a fully sealed heat-shrink film 40. This method utilizes a fully sealed PVC heat-shrink film 40 to completely seal the reagent bottle 10, which not only improves the overall sealing performance of the reagent bottle 10 but also further limits the possibility of the cap 11 loosening during transport.

[0024] like Figures 1-5 As shown, in step C), the tightening direction of reagent bottle 10 and cap 11 is opposite to the tightening direction of sample cylinder 20 and cap 21. Since sample cylinder 20 rotates and moves forward inside the pipe, it is tightened in the direction of rotation. However, reagent bottle 10 is inside sample cylinder 20 and will be subjected to a reverse force. Therefore, this solution requires selecting a reagent bottle whose tightening direction of reagent bottle 10 and cap 11 is opposite to that of sample cylinder 20 and cap 21. When moving inside sample cylinder 20, reagent bottle 10 and cap 11 will not loosen, thus locking the liquid sample inside the bottle and preventing liquid leakage.

[0025] like Figure 4 As shown, in step C), filler 30 is added around the reagent bottle 10 inside the sample cylinder 20, and the sample cylinder cap 21 is tightened. The above solution adds filler 30 around the reagent bottle 10 inside the sample cylinder 20, fixing the reagent bottle inside the sample cylinder 20 and preventing impacts to the reagent bottle 10 inside the sample cylinder 20. This provides shock absorption and buffering when the sample cylinder 20 reaches the terminal of the receiving cabinet, preventing bottle deformation.

[0026] like Figure 3 As shown, reagent bottle 10 is placed into a self-sealing bag and sealed. The self-sealing bag 50 wraps around the top and bottom and folds left and right of reagent bottle 10, and then inserts it into sample cylinder 20. In the above scheme, the reagent bottle 10, which is fully sealed with PVC heat shrink film 40, is placed in the center of the self-sealing bag 50. The remaining bag body on the left and right is wrapped and folded, and the remaining bag body on the top and bottom is wrapped front and back. This packaging method can not only provide an extra layer of sealing protection for reagent bottle 10, but also achieve the same shock absorption and cushioning effect as the filler 30 inside sample cylinder 20.

[0027] like Figures 1-3As shown, in step A), the outer circumferential surface of the bottle cap 11 is provided with anti-slip teeth 12. The anti-slip teeth 12 are set on the outer circumferential surface of the bottle cap 11 using a knurling machine. When the reagent bottle 10 is wrapped with PVC heat shrink film 40, the PVC heat shrink film 40 can adhere to the anti-slip teeth 12, preventing the PVC heat shrink film 40 from rotating with the reagent bottle 10 during transportation.
