Abstract
Description
Technical Field
[0001] The utility model relates to the field of organic carbon analysis instruments, in particular to a sample injection device for an organic carbon analyzer. Background Art
[0002] Solid total organic carbon is measured by a special instrument - solid total organic carbon analyzer. Solid total organic carbon analyzer has the advantages of simple process, good reproducibility, high sensitivity, stability and reliability, and complete oxidation. It is widely used in environmental monitoring and assessment, soil science, agricultural testing, geology and geochemistry, waste treatment and resource utilization, etc. Solid total organic carbon analyzer is mainly heated by a cracking furnace (pre-filled with catalyst and heated to 800℃) to decompose the organic matter in the sample into CO 2 , so as to achieve the purpose of detection.
[0003] At present, the core components used for solid total organic carbon testing are the sampling device and the combustion tube. However, first of all, when taking and placing the sample boat, the existing products require the user to perform a series of cumbersome steps. The user needs to move the upper cover to the side a certain distance so that there is enough space to take and place the sample boat. This movement process requires the user to control the strength and direction, which increases the risk of operating errors, such as the instrument leaking due to the screws not being tightened, and collision damage during the movement of the upper cover. Secondly, when the sampling device is connected to the combustion tube, the end face of the combustion tube needs to be made into a boss shape, and a threaded cap and a sealing ring are used for sealing, which increases the difficulty of sealing and increases the manufacturing cost and complexity of the combustion tube. In addition, the use of a threaded cap and a sealing ring for sealing requires precise control of the tightening force of the threaded cap, otherwise it may cause poor sealing or damage to the combustion tube and the sealing ring. These are all undesirable in the art. Utility Model Content
[0004] In view of the existing problems, the utility model provides a sample introduction device for an organic carbon analyzer, aiming to solve the problems of the existing solid organic carbon analyzer such as complicated operation, poor sealing, high cost, etc.
[0005] In order to solve the above problems, the utility model discloses a sampling device for an organic carbon analyzer, comprising a sampling module, which is connected to a combustion tube; the sampling module comprises a flip cover, on which a rotating shaft is provided, which is connected to a main body seat, in which a combustion tube is inserted; a locking cover module is provided on the side wall of the main body seat.
[0006] Furthermore, a hook is arranged on the flip cover.
[0007] Furthermore, the rotating shaft includes two torsion springs, which are connected via a damping hinge. Both ends of the torsion spring are provided with a support shaft, one end of the support shaft is connected to the flip cover, and the other end is connected to the main body seat.
[0008] Furthermore, the locking cover module includes a compression spring, the compression spring is connected to a hook block, and the hook block is connected to a button.
[0009] Furthermore, the injection module is sequentially connected to the first sealing ring and the second sealing ring.
[0010] Compared with existing utility models, utility models have the following advantages:
[0011] 1. The injection module adopts a flip cover structure. During the opening process, it can be opened slowly and smoothly under the action of the damping hinge and torsion spring, which ensures the stability of the equipment and reduces the damage to the sample boat caused by vibration. In addition, the flip cover is controlled by a button. The user only needs to press the button lightly to open the flip cover easily without manual operation, which greatly simplifies the injection process. It is also simple to close the flip cover, just press it lightly by hand.
[0012] 2. Efficient sealing improves plugging and unplugging efficiency. Two types of sealing rings are used to seal between the injection module and the combustion tube. This design not only ensures the reliability of the seal, but also makes the plugging and unplugging of the combustion tube smoother. The structural design of the double-specification sealing ring reduces the friction during plugging and unplugging, and the operation of personnel saves time and effort, thereby improving the efficiency of replacing catalysts and combustion tubes.
