Description

Technical Field

[0001] This utility model relates to the technical field of reactor sampling equipment, and in particular to a reactor sampling and testing mechanism. Background Technology

[0002] Reactors are widely used containers in chemical, pharmaceutical, food, and new materials industries, primarily for completing various chemical reactions, mixing, or material transformation processes. Their structure typically includes a vessel body, stirring device, heat transfer elements, and sealing components. Capable of withstanding complex conditions such as high temperature, high pressure, and corrosiveness, they are indispensable core devices in experimental research and industrial production. With increasingly demanding process requirements, reactor design is gradually evolving towards precision and multi-functionality to meet the demands for reaction efficiency, product purity, and process controllability.

[0003] During the reaction process, whether the product meets the expected chemical or physical performance indicators needs to be verified through real-time or phased sampling and testing. Therefore, the sampling design of the reaction vessel becomes a critical aspect. In existing technologies, dedicated reaction vessels are typically equipped with a fixed vacuum sampling system, directly connected to the vessel body via built-in pipes. Operators only need to open the valve to extract samples using vacuum negative pressure, offering high convenience. In contrast, ordinary reaction vessels or traditional equipment often rely on external vacuum machines for sampling, requiring the transfer of liquid from the vessel to the testing container via additional hoses or connectors, making the process relatively cumbersome.

[0004] However, while the fixed vacuum sampling system for dedicated reactors is simple to operate, the equipment is expensive and limited by the reactor volume, making it difficult to flexibly adapt to the production needs of different scales. The external vacuum sampling method for ordinary reactors requires external equipment, which not only increases the operation steps and labor costs, but may also lead to sample contamination or inaccurate sampling due to the complexity of operation, thus affecting the reliability of the test results. Utility Model Content

[0005] To overcome the drawbacks of high cost and difficult operation, this utility model provides a sampling and testing mechanism for a reaction vessel, aiming to solve the above-mentioned shortcomings.

[0006] A sampling and testing mechanism for a reaction vessel includes an outer cylinder, an extension tube connected to the top of the outer cylinder, an inner cylinder slidably connected inside the outer cylinder, a water inlet at the bottom of the inner cylinder, the top of the inner cylinder slidably connected inside the extension tube, a return spring sleeved at the bottom of the extension tube, one end of the return spring being connected to the outer cylinder and the other end being connected to the inner cylinder, a sealing cap threaded to the bottom of the inner cylinder, and anti-detachment components for preventing the outer cylinder from falling into the reaction vessel provided on the left and right sides of the inner cylinder.

[0007] As an improvement to the above solution, the anti-detachment component includes a support rod. The support rod is connected to both the left and right ends of the top of the inner cylinder. Multiple tension rods are provided inside the support rod. The largest tension rod is slidably connected inside the support rod. The tension rods are successively nested and slidably connected to each other. The end of the smallest tension rod is connected to an operating handle.

[0008] As an improvement to the above solution, the inner end of the maximum tension rod is connected to a magnet, and the ends of the support rod and all the tension rods are made of magnetic material.

[0009] As an improvement to the above solution, a sealing gasket is provided between the sealing cap and the bottom surface of the inner cylinder.

[0010] As an improvement to the above solution, the rotating handle of the sealing cover has a groove.

[0011] As an improvement to the above solution, a telescopic pad is provided at the top of the outer cylinder. The top of the telescopic pad is connected to the inner cylinder, and the bottom is connected to the outer cylinder. The telescopic pad wraps around the return spring.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. By using glass materials for the outer and inner cylinders, a corrosion-resistant and easily observable sliding fit is formed, thereby achieving visualization and ease of cleaning during the sampling process, ultimately reducing equipment costs and improving versatility.

[0014] 2. Through the elastic wrapping and cooperation of the return spring and the telescopic pad, the inner cylinder forms an automatic sealing action after sliding sampling, thereby realizing the rapid closure of the sampling port and the function of preventing leakage, ultimately achieving the purpose of improving operational reliability and safety.

[0015] 3. Through the telescopic and anti-detachment design of the support rod and multi-section tension rod, the inner cylinder forms an adjustable suspension support action in the reactor, thereby achieving adaptability to different sampling depth scenarios, and ultimately reducing equipment usage limitations and improving operational stability.

[0022] The above-described solution will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of this application. The implementation conditions used in the embodiments may be further adjusted according to the conditions of specific manufacturers, and the implementation conditions not specified are generally those in routine experiments.

[0023] Example: A sampling and testing mechanism for a reaction vessel, such as Figures 1-5 As shown, the device includes an outer cylinder 1, an inner cylinder 2, an extension tube 3, a reset spring 4, a sealing cap 5, and an anti-detachment assembly. The extension tube 3 is connected to the top of the outer cylinder 1, and the inner cylinder 2 is slidably connected inside the outer cylinder 1. The bottom of the inner cylinder 2 has a water inlet 21, and the top of the inner cylinder 2 is slidably connected inside the extension tube 3. Both the outer cylinder 1 and the inner cylinder 2 are made of high borosilicate glass, and the extension tube 3 is made of stainless steel. The bottom of the extension tube 3 is fitted with a reset spring 4, one end of which is connected to the outer cylinder 1, and the other end is connected to the inner cylinder 2. Through compression and rebound, the inner cylinder 2 is automatically reset and the water inlet 21 is sealed, reducing human operation errors and ensuring the reliability of the seal after sampling. The bottom of the inner cylinder 2 is threaded with a sealing cap 5, and the top left and right sides of the inner cylinder 2 are provided with anti-detachment assemblies to prevent the outer cylinder 1 from falling into the reactor.

[0024] like Figure 1 and Figure 2 As shown, the anti-detachment component includes a support rod 6, a tension rod 7, and an operating handle 8. The support rod 6 is connected to both the left and right ends of the top of the inner cylinder 2. Multiple tension rods 7 are installed inside the support rod 6. The largest tension rod 7 is slidably connected inside the support rod 6. The tension rods 7 are nested and slidably connected to each other in stages. The smallest tension rod 7 is connected to the end of the operating handle 8.

[0025] like Figure 5 As shown, it also includes a magnet 9. The inner end of the maximum section tension rod 7 is connected to a magnet 9. The ends of the support rod 6 and all tension rods 7 are made of magnetic material. Strong magnetic adsorption enables the tension rod 7 to be automatically fixed after it is retracted, preventing the tension rod 7 from sliding out on its own during transportation or storage.

[0026] like Figure 4As shown, it also includes a sealing gasket 10. A sealing gasket 10 is provided between the sealing cap 5 and the bottom surface of the inner cylinder 2. The silicone sealing gasket 10 is corrosion resistant, has good elasticity, fills the gap of the threaded connection, and enhances the sealing performance.

[0027] like Figure 4 As shown, the sealing cover 5 has a groove 11 on its rotating handle. The surface of the groove 11 is frosted, which increases the friction of the fingers, making it easier to apply force accurately when rotating the sealing cover 5, avoiding slippage, and improving the efficiency of disassembly and assembly.

[0028] like Figure 1 As shown, it also includes a telescopic pad 12. A telescopic pad 12 is provided between the top of the outer cylinder 1 and the inner cylinder 2. The top of the telescopic pad 12 is connected to the inner cylinder 2, and the bottom is connected to the outer cylinder 1. The telescopic pad 12 wraps around the reset spring 4, which can prevent liquid or impurities from entering the spring gap and extend the service life of the spring.

[0029] First, the staff opens the sampling port of the reactor and vertically inserts the outer cylinder 1 into the reactor, ensuring that the top of the extension tube 3 maintains an appropriate distance from the reactor body. At this time, the support rod 6 contacts the reactor. Then, the staff holds the operating handle 8 with one hand and gently pulls it outward. The multi-section tension rod 7 slides out from the support rod 6 step by step until the smallest section tension rod 7 is fully extended, forming a stable support structure, effectively preventing the inner cylinder 2 from falling downward due to gravity or liquid impact.

[0030] When the bottom of the inner cylinder 2 contacts the solution inside the reactor, the operator places their fingers on the bottom side of the top plate of the outer cylinder 1 and the top surface of the inner cylinder 2, applying uniform downward pressure simultaneously. Under pressure, the inner cylinder 2 slides downwards along the inner wall of the outer cylinder 1, compressing the return spring 4 and the telescopic pad 12. The inlet 21, originally blocked by the bottom of the outer cylinder 1, is gradually exposed as the inner cylinder 2 moves downwards. At this point, the solution flows into the cavity of the inner cylinder 2 through the inlet 21 for sampling.

[0031] After the pressure is stopped, the return spring 4 returns to its original shape due to elastic deformation, pushing the inner cylinder 2 to slide upward. The telescopic pad 12 extends synchronously with the movement of the inner cylinder 2, forming a protective enclosure around the return spring 4. During the upward movement of the inner cylinder 2, the water inlet 21 re-enters the sealed area at the bottom of the outer cylinder 1, achieving automatic sealing and preventing liquid leakage after sampling. The operator holds the support rod 6 and smoothly removes the inner cylinder 2 from the reactor.

[0032] After removing the inner cylinder 2, the staff wiped the remaining liquid at the bottom of the outer cylinder 1 and the inner cylinder 2 with a cleaning cloth, and then pushed the multi-section tension rods 7 back into the support rod 6 in sequence. When pushed to the end, the magnet 9 at the end of the largest tension rod 7 is attracted to the magnetic material on the inner wall of the support rod 6. At the same time, the ends of each tension rod 7 are attracted and fixed to the magnetic material of the support rod 6 or the adjacent tension rod 7 in sequence, preventing the tension rods 7 from slipping out on their own due to shaking during transportation or storage.

[0033] Before testing, the staff rotates the sealing cap 5 at the bottom of the inner cylinder 2, inserting their fingers into the groove 11 of the rotating handle of the sealing cap 5. The groove 11 increases friction, ensuring the sealing cap 5 rotates smoothly. As the threads of the sealing cap 5 gradually separate from the inner cylinder 2, the seal between the sealing gasket 10 and the bottom surface of the inner cylinder 2 is broken, and the sample liquid inside the inner cylinder 2 flows out under gravity. After removing the liquid, the outer cylinder 1, inner cylinder 2, and sealing cap 5 are placed in a cleaning tank. Because all three are made of glass, with smooth and corrosion-resistant surfaces, they can be quickly rinsed clean, preparing for the next sampling.
