Abstract
Description
Technical Field

[0002] In the field of chemical engineering, gas sampling is crucial for analyzing chemical production processes, controlling product quality, and ensuring production safety. Furthermore, gas samplers are required to sample gases used in chemical engineering.
[0003] As disclosed in announcement number CN217132693U, a gas sampler belongs to the field of gas collection technology. This gas sampler includes a gas sampler cylinder with an air intake port and a trigger mechanism installed at both ends. An air intake piston is fitted inside the gas sampler cylinder. The gas sampler cylinder is used to contain the collected gas. The air intake port is used to allow air to enter the gas sampler cylinder. The trigger mechanism is used to automatically draw in air from the air intake piston. The piston handle drives the air intake piston head upward through the air intake piston rod. Gas enters the inner wall of the cylinder from the central circular hole, completing gas sampling. Afterwards, a sealing plate can be pressed into the sealing plate groove as needed to ensure the relative airtightness of the inner wall of the cylinder. Gas sampling is performed using a spring, which pops up with the air intake piston, resulting in fast sampling speed. In this case, a trigger mechanism is used for gas sampling, which can be operated by one hand by the staff, making it convenient and fast.

Detailed Implementation
[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0031] Please see Figures 1-6 The present invention provides the following technical solution:
[0032] To address the problems of poor sealing, easy leakage, and inconvenience in sealing, storing, and transferring the collected gas in existing technologies, this solution provides a leak-proof chemical engineering gas sampler. The sampler includes a collection bracket 1 and a gas collection bottle 6 inserted into the middle of the collection bracket 1. The gas collection assembly comprises a collection cylinder 2 fixed to the upper end of the collection bracket 1, a suction fan 3 installed in the middle of the collection cylinder 2, and a collection hole 4 opened at the upper end of the collection cylinder 2. A limiting component is provided at the lower end of the collection bracket 1. The limiting component drives the gas collection bottle 6 to form a disassembly structure within the collection bracket 1. The limiting component is composed of a movable support plate 11 that flips at the lower end of the collection bracket 1, a fixed connecting bolt 14, a fixed pressure plate 15, and buffer granules 16 located in the middle of the movable support plate 11.
[0033] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, firstly, the gas collection bottle 6 is inserted into the collection bracket 1 from the bottom. A gas sealing valve 7 is installed at the upper end of the gas collection bottle 6, and a gas collection cover 8 is installed at the upper end of the gas sealing valve 7. The gas delivery pipe 5 is inserted into the gas collection cover 8. Simultaneously, a sealing gasket 9 is fitted between the gas delivery pipe 5 and the gas collection cover 8 to improve the sealing effect at the connection. Then, the movable connecting rod 12 is rotated. The movable connecting rod 12 rotates on the left side of the movable support plate 11, and the torsion spring at the connection between the movable connecting rod 12 and the movable support plate 11 elastically deforms. When the movable connecting rod 12 rotates, the movable baffle 13 rotates, and then the movable support plate 11 flips upward. The movable support plate 11 rotates at the lower right end of the acquisition bracket 1. At the same time, after the movable support plate 11 flips, it engages with the lower end of the acquisition bracket 1. At this time, the movable baffle 13 is aligned with the fixed groove 10. Then the movable connecting rod 12 is released directly. At this time, the torsion spring restores its elastic deformation and drives the movable connecting rod 12 to rotate, so that the movable connecting rod 12 engages in the fixed groove 10 opened at the lower left end of the acquisition bracket 1, thereby facilitating the limiting of the movable support plate 11 and the acquisition bracket 1.
[0034] like Figure 3and Figure 4 As shown, the fixed connecting bolt 14, which is threadedly connected to the middle of the movable support plate 11, rotates between the fixed connecting bolt 14 and the fixed pressure plate 15. The fixed connecting bolt 14 drives the fixed pressure plate 15 to move upward, and together with the buffer rubber particles 16, they adhere to the lower end of the gas collection bottle 6, squeezing and limiting the gas collection bottle 6, thereby positioning the gas collection bottle 6 in the middle of the collection bracket 1. Then, the gas sealing valve 7 is opened, and the suction fan 3 is started through the external controller. The suction fan 3 is powered by a built-in lithium battery. After the suction fan 3 is started, the gas from the chemical engineering is sucked into the gas collection bottle 6 for collection. After collection is completed, the gas sealing valve 7 is closed and the suction fan 3 is turned off. The gas is stored in the gas collection bottle 6. Combined with the setting of the gas sealing valve 7, the sealing of the gas during the storage process is improved to prevent gas leakage. Then, the gas collection bottle 6 can be disassembled by reversing the above operation, which facilitates the transfer of gas.
[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
