[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0019] The chemical reagent condensation device based on circulating flow disclosed in this utility model is mainly used in scenarios where current condensation devices do not have the function of changing the spacing between reagent tubes, resulting in poor condensation effect.
[0020] Reference Figures 1-4 A chemical reagent condensation device based on circulating flow includes: a condensation box 1, with a circular hole at the bottom of the condensation box 1, and a rotating seat 2 rotatably connected to the inside of the circular hole via a bearing; a vertical shaft 3, fixedly connected to the upper side of the rotating seat 2; a top box 5, fixedly connected to the top of the condensation box 1; a retractable placement module 4, disposed outside the vertical shaft 3, for storing reagent tubes; and an umbrella-shaped retractable assembly 6, disposed above the vertical shaft 3, for adjusting the state of the retractable placement module 4.
[0021] Specifically, the retractable placement module 4 can disperse the stored reagent tubes during condensation, increasing the space between the reagent tubes, increasing the contact effect between the reagent tubes and the cold air, and improving the condensation efficiency of chemical reagents. At the same time, the reagent tubes are in a non-static state during condensation, which can disrupt the circulation of cold air in the box and further increase the degree of contact with the cold air.
[0022] Reference Figure 1 , Figure 2 and Figure 3 In a preferred embodiment, the retractable placement module 4 includes: two retaining sleeves 401, which are respectively fixedly connected to the outside of the vertical shaft 3, and the two retaining sleeves 401 are arranged vertically; a plurality of first mounting seats 402, which are fixedly connected to the outside of the two retaining sleeves 401, and the plurality of first mounting seats 402 are located outside the retaining sleeves 401 and are circumferentially distributed; and a plurality of placement plates 403, which are arranged on the outside of the vertical shaft 3 and are circumferentially distributed, and each of the plurality of placement plates 403 has two vertically distributed second mounting seats 406 fixedly connected to the side of the plurality of placement plates 403 near the vertical shaft 3.
[0023] In this scheme, the retractable placement module 4 further includes: multiple inserts 404, which are fixedly connected to multiple placement plates 403 respectively, with the inserts 404 located on the side of the placement plate 403 away from the vertical shaft 3; multiple brackets 405, which are fixedly connected to multiple placement plates 403 respectively, with the brackets 405 located below the inserts 404; the first mounting seat 402 on the retaining sleeve 401 and the second mounting seat 406 on the corresponding placement plate 403 are rotatably connected by bearings to a first extension frame 407 and a second extension frame 408, with the first extension frame 407 and the second extension frame 408 rotatably connected by bearings.
[0024] Specifically, the retractable placement module 4 is suitable for storing reagent tubes. The retractable placement module 4 has two states: storage state: the first extension rack 407 and the second extension rack 408 are flipped and stored, and the reagent tubes are placed in a concentrated manner, which facilitates the placement and retrieval of the reagent tubes; condensation state: the door 14 of the condensation box 1 is closed, and the internal space of the box is sealed. With the assistance of the umbrella-shaped retractable component 6, the first extension rack 407 and the second extension rack 408 are unfolded, and the reagent tubes are placed separately. At this time, the distance between the reagent tubes increases, which facilitates the contact between the cold air and the reagent tubes, thereby improving the heat exchange between the reagents and the cold air inside the tubes.
[0025] Reference Figure 2 , Figure 3 and Figure 4 In a preferred embodiment, the umbrella-shaped retractable assembly 6 includes: a movable seat 601 disposed inside the top box 5, the movable seat 601 being located above the vertical shaft 3; a shaft 602 fixedly connected to the lower side of the movable seat 601, the vertical shaft 3 having an insertion hole in the middle, the shaft 602 being slidably connected to the insertion hole of the vertical shaft 3; a top shaft block 606 rotatably connected to the upper side of the movable seat 601 via a bearing; and a hydraulic cylinder 607 fixedly connected to the upper side of the top box 5, the top box 5 having a through hole, the telescopic shaft of the hydraulic cylinder 607 passing through the through hole of the top box 5 and being fixedly connected to the top shaft block 606.
[0026] In this solution, the umbrella-shaped expansion and contraction assembly 6 further includes: multiple third mounting bases 603, which are fixedly connected to the outside of the movable base 601, and the multiple third mounting bases 603 are circumferentially and equidistantly distributed outside the movable base 601; multiple fourth mounting bases 604, which are fixedly connected to multiple placement frames, and the fourth mounting bases 604 are located above the first mounting base 402; and multiple umbrella frames 605, which are rotatably connected to the third mounting bases 603 and the corresponding fourth mounting bases 604 through bearings.
[0027] Specifically, the umbrella-shaped expansion and contraction component 6 is suitable for changing the state of the expansion and contraction placement module 4. By utilizing the umbrella-shaped structure, the expansion and contraction forms of the first extension frame 407 and the second extension frame 408 can be effectively controlled, thereby realizing the gathering and dispersing of the reagent tubes.
[0028] Reference Figure 1 and Figure 2 In a preferred embodiment, a base box 7 is fixedly connected to the lower side of the condenser box 1, a right-angle reducer 8 is fixedly connected inside the base box 7, the output shaft of the right-angle reducer 8 is fixedly connected to the lower side of the rotary seat 2, and a rotary motor 9 is fixedly connected to the outer side of the base box 7. The output shaft of the rotary motor 9 passes through one side wall of the base box 7 and is connected to the input end of the right-angle reducer 8.
[0029] Specifically, the right-angle reducer 8 is used to effectively control the rotation speed of the rotating seat 2, avoiding excessive rotation speed that could cause reagent spillage.
[0030] Reference Figure 1 , Figure 2 and Figure 4 In a preferred embodiment, a flow pipe 10 is fixedly connected to the lower side of the condenser box 1, an air inlet strip 11 on the upper side of the flow pipe 10 communicates with the interior of the condenser box 1, an air inlet pipe 12 is provided on the lower side of the flow pipe 10, and an exhaust pipe 13 is fixedly connected to the outer side of the condenser box 1, the exhaust pipe 13 communicates with the interior of the condenser box 1, and two symmetrical box doors 14 are slidably connected to the condenser box 1.
[0031] Specifically, the air inlet bar 11 supplies air upward from the bottom of the condenser box 1 and discharges it from the exhaust pipe 13, forming a bottom-up airflow state, which makes the contact between the cold air and the reagent tube more uniform. At the same time, the rotating reagent tube and the retractable placement module 4 can disrupt the airflow inside the box, further increasing the contact between the reagent tube and the cold air.
[0032] Working principle: In use, open the box door 14 and insert the reagent tubes into the holder 404 in sequence; close the box door 14, activate the hydraulic rod to extend and move the movable seat 601 downward, the shaft 602 slides downward within the vertical shaft 3, the umbrella frame 605 applies a pushing force to the placement plate 403 as the movable seat 601 moves downward, the placement plate 403 moves away from the vertical shaft 3 after being subjected to force, the first extension frame 407 and the second extension frame 408 unfold, and the reagent tubes in the condenser box 1 are dispersed and unfolded; during condensation, cold air enters the flow pipe 10 from the air inlet pipe 12, and... The cold air enters the condenser 1 through the air inlet 11 and flows upward to exit through the exhaust pipe 13. During this process, the rotating motor 9 drives the rotating seat 2 to rotate at a constant speed. The rotating reagent tube can disrupt the airflow in the condenser 1 and increase the contact effect between the cold air and the reagent tube. At the same time, the rotating reagent tube can keep the reagent in the tube in a non-static state and accelerate the heat exchange between the reagent and the cold air in the chamber. After rotating for a period of time, the rotating seat 2 will stop, and the cold air will continue to be delivered into the condenser 1, and the reagent in the reagent tube will undergo further condensation.
[0033] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
