[0002] Pure steam is an important thermodynamic medium for sterilizing equipment and instruments that come into direct contact with the product before injection production. The Chinese Pharmacopoeia stipulates that the quality standard for pure steam condensate is the standard for water for injection, so regular sampling and testing of pure steam is required. In related art, a pure steam cooling sampling device has been proposed. This device primarily involves providing a pipe for circulating cooling water within a housing, and then attaching a pure steam condenser to the pipe so that the temperature of the cooling water can be transferred to the pure steam condenser to achieve steam liquefaction. This approach presents at least the following problems:
[0003] Although attaching the steam condenser to the pipeline can liquefy pure steam through temperature transfer, the temperature transfer efficiency is not high due to the limited area where the steam condenser is attached to the pipeline. In addition, the pure steam and cooling water flow continuously and the flow distance is limited, resulting in a low pure steam liquefaction rate and waste of pure steam. Utility Model Content
[0004] The embodiment of the present application provides a pure steam cooling sampling device to improve the problem of low pure steam liquefaction rate and resulting pure steam waste.

[0024] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making any creative efforts shall fall within the scope of protection of this application.
[0025] In the description of this application, it should be understood that the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or the number of the technical features indicated. Therefore, a feature specified as "first" or "second" may explicitly or implicitly include one or more features. In the description of this application, "plurality" means two or more, unless otherwise specifically specified.
[0026] See Figure 1 and Figure 2 An embodiment of the present application provides a pure steam cooling sampling device, comprising a cylinder 1 and a cooling coil assembly 2. The cylinder 1 is provided with a cooling cavity 13, and the two ends of the cylinder 1 are respectively sealed with a first sealing cover 11 and a second sealing cover 12. The first sealing cover 11 is provided with a first connecting pipe 111, and the second sealing cover 12 is provided with a second connecting pipe 121. Both the first connecting pipe 111 and the second connecting pipe 121 are in communication with the cooling cavity 13. The cooling coil assembly 2 is fixed to both the first sealing cover 11 and the second sealing cover 12. The cooling coil assembly 2 includes a cooling coil 21, which is provided in the cooling cavity 13 and has two ends extending to the outside of the two ends of the cylinder 1.
[0027] The technical solution provided by the present application utilizes the cooling cavity 13 in the cylinder 1 to circulate the coolant, and the cooling coil 21 is arranged in the cooling cavity 13, so that the pure steam flowing in the cooling coil 21 can be liquefied by the action of the coolant, and because the cooling coil 21 is located in the cooling cavity 13 filled with coolant, the outer periphery of the cooling coil 21 can be affected by the coolant. Compared with the related art, only the part to which the coil is attached can be affected by the coolant. The cooling coil 21 of the present application has a better liquefaction effect on the pure steam, a faster rate, and improves the liquefaction rate of the pure steam. In detail, it is mainly by directly placing the cooling coil 21 into the cooling cavity 13 filled with coolant, so that the coolant can wrap the cooling coil 21 in all directions, thereby increasing the temperature exchange area between the coolant and the cooling coil 21, and then, under the limited length of the cooling coil 21, the pure steam can be liquefied as quickly as possible, thereby improving the liquefaction rate.
[0028] In some embodiments, the cooling coil 21 is spiral, which is beneficial to increasing the path length of the pure steam flow, thereby increasing the time for the pure steam to exchange heat in the environment where the cooling liquid wraps the cooling coil 21, and ensuring the full liquefaction of the pure steam as much as possible.
[0029] In some embodiments, the cooling coil assembly 2 further includes a first quick-release cover 22 and a second quick-release cover 23. The first quick-release cover 22 is provided with a first through-hole and a second through-hole, while the second quick-release cover 23 is provided with a third through-hole and a fourth through-hole. The first quick-release cover 22 is mounted on the first sealing cover 11, with the first connecting tube 111 passing through the first through-hole and being removably connected to the first quick-release cover 22. One end of the cooling coil 21 passes through the second through-hole, and the second quick-release cover 23 is mounted on the second sealing cover 12. The second connecting tube 121 passes through the third through-hole, and the other end of the cooling coil 21 passes through the fourth through-hole and is removably connected to the second quick-release cover 23. The first quick-release cover 22 and the first sealing cover 11 can be connected by snapping, threading, or a clamp. Similarly, the second quick-release cover 23 and the second sealing cover 12 can also be connected by snapping, threading, or a clamp, as long as the connection is removable. In this embodiment, the first quick-release cover 22 is connected to the first sealing cover 11 with a clamp, and the second quick-release cover 23 is connected to the second sealing cover 12 with a clamp, facilitating the removal of the two quick-release covers. Because the cooling coil 21 is connected to the first quick-release cover 22 and the second quick-release cover 23, the cooling coil 21 can also be removed from the cylinder 1 when the quick-release covers are removed, facilitating replacement and cleaning. The cooling coil 21 can be removed by separating it from the first quick-release cover 22 or the second quick-release cover 23, then removing the separated quick-release cover from the cylinder 1, and then removing the other quick-release cover connected to the cooling coil 21 from the cylinder 1.
[0030] In some embodiments, the inner walls of the first through hole, the second through hole, the third through hole and the fourth through hole are provided with sealing rings, so that when the connecting pipe is connected to the through hole, the sealing ring can be squeezed to form a seal. Similarly, when the cooling coil 21 is connected to the through hole, sealing is also achieved by squeezing the sealing ring.
[0031] In some embodiments, the air inlet 211 of the cooling coil 21 passes through the second through-hole, the water outlet 212 of the cooling coil 21 passes through the fourth through-hole, the first connecting pipe 111 is the water outlet connecting pipe, and the second connecting pipe 121 is the water inlet connecting pipe. This arrangement ensures that the direction of pure steam flow in the cooling coil 21 is opposite to the direction of cooling water flow in the cylinder 1, which facilitates heat exchange between the cooling water and the pure steam.
[0032] Furthermore, the air inlet 211 and the water outlet connecting pipe are located at the top of the cylinder 1, and the water outlet 212 and the water inlet connecting pipe are located at the bottom of the cylinder 1, so that the flow direction of the cooling water is from bottom to top, and the flow direction of the pure steam is from top to bottom, which is conducive to temperature exchange between the cooling water and the pure steam and improves the liquefaction efficiency.
[0033] A water pump is connected to the water outlet connecting pipe or the water inlet connecting pipe to provide power for the cooling water to flow from bottom to top.
[0034] Furthermore, a plurality of lugs 14 are provided on the outer circumference of the cylinder 1. When the sampling device is used, the cylinder 1 can be fixed vertically on the bracket by using the lugs 14, ensuring that the cylinder 1 is always in a vertical state, thereby preventing the flow rate of pure steam and cooling water from suddenly changing due to the shaking of the cylinder 1.
[0035] In some embodiments, the cooling coil 21 includes three cooling coils 21, and the three cooling coils 21 are all arranged in the cooling chamber 13. The air inlet 211 of each coil can be connected to a pure steam generating device, thereby improving the pure steam in the three cooling coils 21 can be synchronously cooled in the cooling chamber 13, thereby improving the liquefaction efficiency.
[0036] Furthermore, the three cooling coils 21 are all spiral, and the pitches of the three cooling coils 21 are all different, so that the three cooling coils 21 can be arranged nearly coaxially while no structural interference occurs between the three coils, effectively reducing the space occupied by the three cooling coils 21 in the cooling chamber 13, achieving a compact structure, and reducing the volume of the sampling device.
[0037] In some embodiments, see Figure 3 The pure steam cooling sampling device also includes a sampling chamber 3, which is connected to the water outlet 212 of the cooling coil 21 and is used to receive the liquefied steam condensate. The water outlet 212 and the sampling chamber 3 are threadedly connected, and sealing tape is wrapped around the threads of the water outlet 212. When the water outlet 212 and the sampling chamber 3 are threadedly connected, the sealing tape is squeezed, thereby achieving a better sealing effect.
[0038] It should be noted that the cooling coil 21 and the cylinder 1 are both made of stainless steel to prevent pure steam and cooling water from corroding the cylinder 1 and the cooling coil 21 and to extend the service life of the device.
