Description

Technical Field

[0001] This utility model relates to the field of sampling equipment technology, specifically a catalyst sampler. Background Technology

[0002] In numerous fields involving catalyst applications, such as chemical engineering and environmental protection, accurate catalyst sampling and analysis are crucial for ensuring stable production processes, optimizing catalyst performance, and assessing their lifespan. The quality of catalyst sampling directly impacts the reliability of subsequent analytical results, thereby affecting the efficiency and cost control of the entire production system.

[0003] Existing catalyst sampling equipment mostly adopts a relatively basic design architecture, lacking innovation and practicality in its overall structure. It typically consists of only a simple container and a single sampling pipe, with conventional connections between components. For example, CN215640310U discloses a catalyst sampler with a fixed sampling pipe length and angle, which cannot be flexibly adjusted according to the actual sampling environment. When sampling from different locations or depths within the reactor is required, operators often struggle to accurately deliver the sampling pipe to the target location, potentially requiring additional tools or complex operations, increasing the difficulty and time cost of sampling. Utility Model Content

[0004] The purpose of this invention is to provide a catalyst sampler to solve the problem of inconvenient sampling in existing catalyst sampling equipment mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A catalyst sampler includes a sampling bottle for sampling the catalyst, wherein a negative pressure extraction seat that is easy to disassemble is installed on the top of the sampling bottle, and a sampling tube is connected to the top of the negative pressure extraction seat.

[0007] A connector plug is installed on the top of the sampling bottle;

[0008] The negative pressure extraction base has a built-in negative pressure fan and a battery that provides power to the negative pressure fan. The bottom of the negative pressure extraction base has a connecting slot with a matching cross-sectional size and an interference fit. The air inlet of the negative pressure fan is connected to the inside of the sampling bottle through an exhaust pipe. A sealing gasket is provided on the top of the connecting slot.

[0009] The end of the sampling tube furthest from the negative pressure extraction seat is connected to a retractable corrugated tube.

[0010] Preferably, the sampling bottle is a transparent bottle with a handle on its outer wall for easy handling. The transparent material allows the operator to clearly observe the sampling status of the catalyst inside, such as its level, color, and state, facilitating timely monitoring of sampling progress and sample information. The handle provides a convenient grip, making it easy to operate the sampler, especially when moving the sampler or adjusting its position, enhancing operational stability and convenience, and improving sampling efficiency.

[0011] Preferably, the top of the negative pressure extraction base is equipped with a control switch for starting and stopping the negative pressure fan. This control switch allows operators to conveniently and quickly control the working status of the negative pressure fan. Before sampling, the negative pressure fan can be turned on as needed to begin sampling; after sampling is completed, the negative pressure fan can be turned off promptly to avoid energy waste and ineffective equipment operation. This centralized control method improves operational flexibility and makes the sampling process more controllable.

[0012] Preferably, the outer wall of the negative pressure extraction base is embedded with a dustproof mesh that communicates with the air outlet of the negative pressure fan. The dustproof mesh effectively prevents external dust and impurities from entering the negative pressure extraction base. During operation, airflow is discharged from the outlet. Without the protection of the dustproof mesh, dust may enter the negative pressure extraction base with the airflow, contaminating internal components, affecting the normal operation of the negative pressure fan, and even shortening the equipment's lifespan. The dustproof mesh ensures the cleanliness of the equipment's interior, improving its stability and reliability.

[0013] Preferably, the sealing gasket is a silicone gasket with a thickness of 1-3 mm. Silicone gaskets possess excellent elasticity and sealing performance. When the negative pressure extraction seat is connected to the sampling bottle, the silicone gasket tightly fills the gap at the connection point, effectively preventing air leakage and ensuring a stable negative pressure environment is formed inside the sampling bottle, thereby improving the accuracy and efficiency of sampling. The 1-3 mm thickness design ensures that the gasket has sufficient elasticity to accommodate minor deformations at the connection point, while avoiding excessive thickness that could affect component assembly.

[0014] Preferably, the end of the sampling tube connected to the negative pressure extraction seat is provided with a connector, which communicates with the inside of the sampling bottle. This connector creates an effective airflow channel between the sampling tube and the inside of the sampling bottle. Under the action of the negative pressure fan, the catalyst can smoothly pass through the sampling tube and connector into the sampling bottle, ensuring a smooth sampling process. Simultaneously, this connector method facilitates the installation and removal of the sampling tube, making equipment maintenance and replacement easier.

[0015] Preferably, a weighted ball is installed at the end of the corrugated tube furthest from the sampling tube. The weighted ball, using its own gravity, allows the corrugated tube to hang more downwards during sampling, facilitating deeper access to the catalyst location, especially in areas that are deep, confined, or where the catalyst is densely packed. This significantly improves the flexibility and accuracy of sampling, ensuring that representative catalyst samples are obtained.

[0016] Compared with existing technologies, the advantages of this utility model are as follows: In this catalyst sampler, the sampling bottle is used to hold the extracted catalyst sample. The top-mounted, easily detachable negative pressure extraction seat has a built-in negative pressure fan and battery, which can provide the negative pressure power required for extracting the catalyst. The connection slot at the bottom of the sampler is interference-fitted with the connection plug at the top of the sampling bottle, which is convenient for disassembly and assembly and has a stable connection. The sealing gasket at the top of the connection slot can enhance the sealing performance and prevent air leakage. The air inlet of the negative pressure fan is connected to the inside of the sampling bottle through the exhaust pipe, which can draw the catalyst into the sampling bottle. The end of the sampling tube away from the negative pressure extraction seat is connected to a retractable corrugated tube, which allows for flexible adjustment of the sampling position. This makes the catalyst sampler easy to operate, has a reasonable structure, and can effectively complete the catalyst sampling work. Attached Figure Description

Therefore, they should not be construed as limitations on this utility model.

[0026] A catalyst sampler, such as Figures 1-3 As shown, the device includes a sampling bottle 10 for catalytic converter sampling. A detachable negative pressure extraction seat 20 is mounted on the top of the sampling bottle 10, and a sampling tube 30 is connected to the top of the negative pressure extraction seat 20. A connector 12 is mounted on the top of the sampling bottle 10. The negative pressure extraction seat 20 contains a built-in negative pressure fan 24 and a battery 23 that provides power to the negative pressure fan 24. A connector slot 25, with a cross-sectional size matching the connector 12 and an interference fit, is provided at the bottom of the negative pressure extraction seat 20. The air inlet of the negative pressure fan 24 is connected to the inside of the sampling bottle 10 via an exhaust pipe 27. A sealing gasket 26 is provided on the top of the connector slot 25. A retractable corrugated pipe 31 is connected to the end of the sampling tube 30 away from the negative pressure extraction seat 20, and the sampling bottle 10 is used to hold the sample. The catalyst sampler is placed in a negative pressure extraction base 20, which is easy to install and remove. It has a built-in negative pressure fan 24 and a battery 23, which can provide the negative pressure power required for catalyst extraction. The connection slot 25 at the bottom of the base fits into the connection plug 12 at the top of the sampling bottle 10, which is convenient for disassembly and assembly and has a stable connection. The sealing gasket 26 at the top of the connection slot 25 can enhance the sealing and prevent air leakage. The air inlet of the negative pressure fan 24 is connected to the inside of the sampling bottle 10 through the exhaust pipe 27, which can draw the catalyst into the sampling bottle 10. The end of the sampling tube 30 away from the negative pressure extraction base 20 is connected to a retractable corrugated pipe 31, which allows for flexible adjustment of the sampling position. This makes the catalyst sampler easy to operate, has a reasonable structure, and can effectively complete the catalyst sampling work.

[0027] Furthermore, the sampling bottle 10 is a transparent bottle, and a hand handle 11 is installed on the outer wall for easy handing, so that the operator can directly observe the sampling of the catalyst inside the sampling bottle 10. At the same time, the hand handle 11 makes it convenient for the operator to hold the sampler and operate it, improving the ease of use.

[0028] The negative pressure extraction base 20 is equipped with a control switch 21 on its top for controlling the start and stop of the negative pressure fan 24, which allows the operator to easily control the working status of the negative pressure fan 24 and turn the negative pressure extraction function on or off according to actual needs, making the operation more flexible.

[0029] Specifically, a dustproof mesh 22 is embedded on the outer wall of the negative pressure extraction seat 20, which is connected to the air outlet of the negative pressure fan 24. This prevents dust and other impurities from entering the interior of the negative pressure extraction seat 20 when the negative pressure fan 24 is working, thus protecting the negative pressure fan 24 and other components and extending the service life of the equipment.

[0030] It is worth noting that the sealing gasket 26 is made of silicone and has a thickness of 1-3mm, which gives the sealing gasket 26 good elasticity and sealing performance. It can effectively fill the gap between the connecting slot 25 and the connecting plug 12, enhance the sealing of the connection between the negative pressure extraction seat 20 and the sampling bottle 10, and prevent air leakage from affecting the sampling effect.

[0031] It is worth noting that the end of the sampling tube 30 connected to the negative pressure extraction seat 20 is provided with a connector 33. The connector 33 is connected to the inside of the sampling bottle 10, so that the sampling tube 30 can form an effective airflow channel with the inside of the sampling bottle 10 through the connector 33, ensuring that the catalyst can be smoothly drawn into the sampling bottle 10.

[0032] In addition, a weighted ball 32 is installed at the end of the bellows 31 away from the sampling tube 30, which allows the bellows 31 to hang down better during sampling, making it easier to reach the location of the catalyst for sampling, thus improving the accuracy and efficiency of sampling.

[0033] The working principle of this catalyst sampler:

[0034] The operator first holds the handle 11 on the sampling bottle 10 and inserts the connecting slot 25 at the bottom of the negative pressure extraction base 20 into the connecting plug 12 at the top of the sampling bottle 10 with an interference fit. The sealing gasket 26 at the top of the connecting slot 25 ensures the sealing of the connection. Then, the operator presses the control switch 21 at the top of the negative pressure extraction base 20 to start the negative pressure fan 24, so that its air inlet end generates negative pressure inside the sampling bottle 10 through the exhaust pipe 27.

[0035] Next, the operator holds the sampling tube 30 and stretches the corrugated tube 31 at its end. Using the gravity of the weighted ball 32 at the end of the corrugated tube 31, the corrugated tube 31 is pushed into the location of the catalyst. Under negative pressure, the catalyst will enter the sampling bottle 10 through the corrugated tube 31, the sampling tube 30, and the insertion tube 33. During this process, the dustproof net 22 at the air outlet of the negative pressure fan 24 can prevent dust from entering the negative pressure extraction seat 20.

[0036] After sampling is completed, press the control switch 21 again to turn off the negative pressure fan 24, and finally remove the negative pressure extraction seat 20 from the sampling bottle 10. Then, the catalyst in the sampling bottle 10 can be processed.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
