Abstract
Description
Technical Field
[0001] This application relates to the technical field of tube bottle drying, and particularly to a tube bottle dryer. Background Art
[0002] Currently, most liquid chromatography analyzers have specially matched sample injection bottles, and generally multiple sample injection bottles are required for one liquid chromatography analysis measurement, such as 50 - 100 sample injection bottles. To ensure the accuracy of the analysis results and the reusable use of the sample injection bottles, the sample injection bottles need to be cleaned before or after sample injection. After being washed with water, there is often still water remaining on the bottle wall of the sample injection bottle. To avoid stains remaining in the sample injection bottle after a long time and to meet the requirement that the washed sample injection bottle can be quickly put into use, the washed sample injection bottle also needs to be dried in time. Since the bottle mouth of the liquid phase sample injection bottle is small, it can usually only be quickly dried. If multiple sample injection bottles are manually dried simultaneously, the drying efficiency is low.

[0022] The drying tube is provided on the top surface of the seat cover.
[0023] In some embodiments of the present application, the aperture diameter of the air blowing port is the same as that of the ventilation hole;
[0024] Or, in the axial direction of the drying tube, the aperture diameter of the air blowing port gradually increases along the blowing direction.
[0025] In some embodiments of the present application, the vial desiccant further includes an elastic collar, and the collar includes:

[0058] In addition, the mention of "embodiment" herein means that a specific feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of this application. The phrase appears at various positions in the description and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.
[0059] The embodiment of the present application provides a tube and bottle dryer 100, which is applicable to internally drying pipe fittings and bottle parts, and is usually applied to scenarios such as medicine, chemical industry, and laboratories. It should be noted that the pipe fittings herein include but are not limited to test tubes, and the bottle parts include but are not limited to flasks and liquid phase injection bottles 200. It should be emphasized that the tube and bottle dryer 100 of the embodiment of the present application is more applicable to the internal drying of the liquid phase injection bottle 200. For the convenience of description, the liquid phase injection bottle 200 will be taken as an example of the tube and bottle in the following description.
[0060] As Figure 1 and Figure 2 shown, the tube and bottle dryer 100 includes a machine table 1, a gas supply device 2 and a drying tube 3. Among them, an air flow cavity 11 (see Figure 2 ) is formed inside the machine table 1, and the gas supply device 2 is connected to the machine table 1 and used to transport the target gas to the air flow cavity 11. It can be understood that the gas supply device 2 is communicated with the air flow cavity 11. For the convenience of centrally drying a plurality of liquid phase injection bottles 200, the drying gas is concentrated in the air flow cavity 11 and then separately supplied to each liquid phase injection bottle 200 to dry it, which is beneficial to improving the drying efficiency.
[0061] Specifically in this embodiment, the target gas can be nitrogen, and the gas supply device 2 can be a compression compressor. Of course, in other embodiments, the target gas can also be other suitable gases.
[0062] Again as Figure 1 and Figure 2 shown, in order to achieve centralized drying of a plurality of tube and bottles such as the liquid phase injection bottles 200, a plurality of drying tubes 3 are provided. The plurality of drying tubes 3 are arranged vertically on the top surface of the machine table 1 at intervals. An air vent 31 is axially formed inside each drying tube 3. Among them, one end (specifically the bottom end) of the air vent 31 is an air inlet 311 communicated with the air flow cavity 11, and the other end (specifically the top end) of the air vent 31 is a blowing port 312 communicated with the outside.
[0063] In addition, the outer diameter of the drying tube 3 is smaller than the inner diameter of the tube vial (specifically, it can be the liquid-phase injection vial 200), so that a fluid channel is formed between the outer wall of the drying tube 3 and the inner wall of the tube vial when the tube vial is reversely sleeved on the corresponding drying tube 3. It can be understood that when the tube vial is reversely sleeved on the corresponding drying tube 3, the air flow cavity 11, the air inlet 311, the ventilation hole 31, the air blowing port 312, the inner cavity of the tube vial near the inner bottom wall and the fluid channel can jointly form a target gas circulation channel. In this way, when the tube vial is reversely sleeved on the corresponding drying tube 3, if it is necessary to dry the tube vial, the gas supply device 2 can be directly turned on, and the gas supply device 2 can then transport target gases such as nitrogen to the air flow cavity 11. Then, the target gas in the air flow cavity 11 can be blown towards the inner bottom of the tube vial along the corresponding air inlet 311, ventilation hole 31 and air blowing port 312, so as to enter the inner cavity of the tube vial and flow out of the tube vial reversely along the fluid channel in the inner cavity of the tube vial.
[0064] It can be understood that when the target gas is blown towards the inner bottom of the tube vial (specifically, it can be the liquid-phase injection vial 200), on the one hand, the target gas can gradually disperse the liquid at the inner bottom of the tube vial towards the surroundings. Eventually, the liquid at the bottom of the vial and the liquid on the inner wall of the tube vial will together quickly drip from the bottle mouth of the tube vial to the machine table 1 under the action of gravity along the fluid channel, so as to accelerate the draining of the liquid in the tube vial; on the other hand, after the target gas enters the inner cavity of the tube vial, the air flow blowing towards the bottom of the tube vial will return at the bottom of the vial and blow out from the bottle mouth of the tube vial along the fluid channel at a certain speed. Obviously, when the target gas flows in the circulation channel, it can dry the inner wall of the tube vial, which is beneficial to accelerating the drying of the inner wall of the tube vial.
[0065] It should be noted that specifically in this embodiment, the gas supply device 2 and the machine table 1 are detachably connected (of course, they can also be fixedly connected). A handle (not shown in the figure) can be provided on the side wall of the machine table 1. In this way, when not in use, the gas supply device 2 and the machine table 1 can be directly disassembled and stored independently or together, which is convenient for handling and transportation; when in use, the machine table 1 can be directly lifted from the storage box or storage bag with the handle, or the machine table 1 can be directly manually carried out, or carried from one place to another by hand, placed on a target workbench such as a desktop or an experimental tabletop, and the gas supply device 2 and the machine table 1 are detachably connected by an air pipe. After the tube vial to be dried 3 is reversely buckled, the gas supply device 2 can be turned on for drying. The drying operation is convenient and fast, and the entire tube vial dryer 100 is portable and has a simple structure.
[0066] In summary, compared with the prior art, the tube vial dryer 100 has at least the following beneficial effects:
[0067] The tube bottle dryer 100 forms an air flow cavity 11 inside the machine platform 1, arranges multiple drying tubes 3 with ventilation holes 31 axially formed therein at intervals and vertically on the top surface of the machine platform 1. When the tube bottle is reversely sleeved on the corresponding drying tube 3, a fluid channel can be ensured to be formed between the outer wall of the drying tube 3 and the inner wall of the tube bottle. In this way, the air flow blowing from the air flow cavity 11 through the air blowing port 312 of the ventilation hole 31 to the inner bottom of the tube bottle can not only blow the liquid at the bottom of the bottle to the surrounding, and finally the liquid on the inner wall of the tube bottle and the liquid at the bottom of the bottle can quickly drip out of the tube bottle under the action of gravity along the fluid channel, achieving the preliminary drying of the tube bottle. At this time, the fluid channel can be used as a liquid flow channel; in addition, the air flow blowing to the inner bottom of the tube bottle can also flow out of the bottle mouth of the tube bottle along the fluid channel to achieve the thorough drying of the bottom and inner wall of the tube bottle. At this time, the fluid channel can be used as an air flow channel for the target gas. Generally speaking, the tube bottle dryer 100 belongs to a portable tube bottle dryer 100, with a simple structure, convenient and fast drying operation, low price and high cost performance, which is conducive to being vigorously promoted and used.
[0068] In order to enable the personnel in the technical field to better understand the solution of the present application, the following will combine the attached Figures 1 to 12 to clearly and completely describe the technical solutions in the embodiments of the present application.
[0069] In some embodiments of the present application, to further facilitate the drying of the tube bottle, the length of the drying tube 3 is greater than the depth of the tube bottle. In this way, when the tube bottle is buckled on the top end of the drying tube 3, the bottom of the tube bottle can be supported by the top end of the drying tube 3, and there is a large distance between the bottle mouth of the tube bottle and the end of the drying tube 3 close to the machine platform 1. That is, the tube bottle can be completely lifted by the drying tube 3, and a large air flow and / or water flow dispersion space is provided for the outlet of the fluid channel, which is conducive to accelerating the flow of the air flow and / or water flow in the fluid channel, thereby being conducive to further improving the drying efficiency.
[0070] And / or, when the tube bottle is reversely sleeved on the drying tube 3, in order to enable the air flow in the tube bottle and the liquid flow at the inner bottom of the tube bottle to enter the fluid channel during the process of blowing air into the tube bottle, a circulation hole 313 (see Figure 13 ) is axially formed at the top end of each drying tube 3 along the axis of the drying tube 3. Among them, the air blowing port 312 can communicate with the fluid channel through the circulation hole 313. It can be understood that when the tube bottle is reversely sleeved on the corresponding drying tube 3, even if the top end of the drying tube 3 abuts against the inner bottom of the tube bottle, the air flow blowing from the air blowing port 312 to the inner bottom of the tube bottle and the liquid at the inner bottom of the tube bottle can both enter the fluid channel through the circulation hole 313 of the drying tube 3.
[0071] And / or, in some other embodiments of the present application, during the process of blowing air into the vial, there is a gap between the top end of the drying tube 3 and the inner bottom of the vial in the axial direction of the drying tube 3. In other words, during the drying process of the vial, the vial can be lifted by the target air flow blown out from the air outlet 312 of the ventilation hole 31, so as to be separated from the supporting effect of the top end of the drying tube 3. It can be understood that the lifting force of the target air flow blown out from the air outlet 312 is greater than the sum of the self-weights of the vial and the liquid therein. In this way, by lifting the vial slightly away from the drying tube 3, on the one hand, it is beneficial to dry the vial faster and more thoroughly, and on the other hand, it can ensure that the blown target gas can smoothly enter the fluid channel for flow, so as to facilitate drying the inner wall of the vial and ensuring that the liquid at the inner bottom of the vial can also smoothly enter the fluid channel and flow out of the vial under the action of its own weight.
[0072] It should be noted that the air pressure of the target gas blown out from the air outlet 312 can be controlled by existing or newly created structures, such as directly controlling through the valve of the air supply device, etc., and specifically can be determined according to actual needs, as long as the vial can be slightly lifted away from the top end of the drying tube 3 during blowing, and a certain gap is ensured between the inner bottom of the vial and the top end of the drying tube 3, which will not be elaborated here.
[0073] In some embodiments of the present application, a water collecting groove (not shown in the figure) is recessed on the top surface of the machine platform 1, and each drying tube 3 is arranged on the bottom surface of the water collecting groove. In this way, the liquid flowing out of the vial can be centrally stored in the water collecting groove, and will not flow and spread on the table surface of the machine platform 1, or even overflow outside the machine platform 1, for example, overflow from the machine platform 1 to the workbench surface. Instead, after the vial is dried, the water in the water collecting groove can be poured out.
[0074] And / or, in some embodiments of the present application, as Figure 1 and Figure 2 shown, all the drying tubes 3 are arranged in an array, and the gap between two adjacent drying tubes 3 is greater than the maximum outer diameter of the vial. In this way, it is beneficial to ensure that when two vials are respectively sleeved upside down on two adjacent drying tubes 3, the outer walls of the two vials will not interfere with each other.
[0075] In some embodiments of the present application, to further accelerate the drying of the vial, the vial desiccant further includes a heating component (not shown in the figure). Among them, the heating component is arranged in the air flow cavity 11 and is mainly used to heat the target gas in the air flow cavity 11. In this way, after the heating component heats the target gas in the air flow cavity 11, the target gas entering from the air inlet 311, passing through the ventilation hole 31 and blown out from the air outlet 312 can have a temperature higher than the normal temperature. Obviously, the heated target gas can not only dry the vial, but also have a drying effect.
[0076] In some embodiments of the present application, as Figure 1 、 Figure 2 andFigure 4 As shown, for the convenience of production, manufacturing, installation, commissioning, and later maintenance, etc., the machine platform 1 includes a pedestal 12 and a pedestal cover 13. A groove 121 is recessed on the top surface of the pedestal 12 (see Figure 4 ), and the pedestal cover 13 is detachably covered on the pedestal 12 to seal the groove 121, so as to jointly enclose an air flow chamber 11 with the pedestal 12 (see Figure 2 ).
[0077] Again, as Figure 1 and Figure 4 shown, a connector 122 communicating with the groove 121 is provided on one side wall of the pedestal 12. Among them, the connector 122 is mainly used to connect the air supply device 2.
[0078] In addition, as Figure 4 and Figure 5 shown, a drying pipe 3 is provided on the top surface of the pedestal cover 13.
[0079] Regarding the blowing port 312 of the drying pipe 3, optionally, in the first specific embodiment, as Figure 6 and Figure 7 shown, the aperture of the blowing port 312 of the vent hole 31 of the drying pipe 3 is the same as the aperture of the vent hole 31.
[0080] Or, in the second specific manner, as Figure 6 and Figure 8 shown, along the axial direction of the drying pipe 3, the aperture of the blowing port 312 gradually increases along the blowing direction. In this way, the target gas blown out from the blowing port 312 can blow towards the inner bottom of the tube bottle with a larger coverage area under the condition that the impact force is basically unchanged, so as to facilitate ensuring that the inner bottom of the tube bottle is dried more evenly, and further improving the drying effect of the tube bottle. Exemplarily, the blowing hole can be a conical hole or a trumpet hole.
[0081] Or, in the third specific manner, as Figure 6 , Figure 9 and Figure 10 shown, the tube bottle desiccant further includes an elastic collar 4 (see Figure 9 or Figure 10 ), and the collar 4 includes a sleeve portion 41 and an anti-abrasion portion 42. The sleeve portion 41 is sleeved on the outer peripheral wall of the top end of the drying pipe 3; the anti-abrasion portion 42 is connected to the sleeve portion 41 and is sleeved on the end wall of the top end of the drying pipe 3. It can be understood that the sleeve portion 41 is arranged in the radial direction of the drying pipe 3, and the anti-abrasion portion 42 is arranged in the axial direction of the drying pipe 3.
[0082] In such as Figure 9 or Figure 10As shown, at the position corresponding to the air blowing port 312 of the drying tube 3, the abrasion prevention part 42 is provided with an avoidance hole 421 along the axial direction of the drying tube 3, wherein the avoidance hole 421 communicates with the air blowing port 312. It can be understood that the target gas in the ventilation hole 31 needs to be blown out through the air blowing port 312 and the avoidance hole 421 in sequence.
[0083] Optionally, as Figure 9 shown, the aperture of the avoidance hole 421 is the same as that of the air blowing port 312; or, as Figure 10 shown, the aperture of the avoidance hole 421 gradually increases along the blowing direction. In this way, the target gas blown out from the avoidance hole 421 can blow towards the inner bottom of the tube bottle with a larger coverage area under the condition that the impact force remains basically unchanged, thereby facilitating ensuring that the inner bottom of the tube bottle is dried more evenly, and further improving the drying effect of the tube bottle. Exemplarily, the air blowing hole can be a conical hole or a trumpet hole.
[0084] And / or, optionally, as Figure 9 and Figure 10 shown, along the axial direction of the drying tube 3, the outer diameter of the outer peripheral wall of one end of the collar 4 close to the air blowing port 312 gradually increases along the blowing direction. Exemplarily, the outer peripheral wall surface of one end of the collar 4 close to the air blowing port 312 is an inclined surface. In this way, on the one hand, by increasing the supporting surface of the drying tube 3 for the inner bottom of the tube bottle, it is beneficial to improve the supporting stability of the drying tube 3 for the tube bottle when no air is blown, and it is also beneficial to increase the fluid channel between the outer wall of the drying tube 3 and the inner wall of the tube bottle; on the other hand, when the tube bottle, such as the liquid phase injection bottle 200, is just sleeved into the drying tube 3, the inclined outer peripheral wall surface of the collar 4 can facilitate the elastic deformation of the collar 4, which is beneficial to the small bottle mouth of the liquid phase injection bottle 200 being more easily sleeved in; on the third hand, after having the collar 4, a smaller drying tube 3 can be directly used to ensure the stable support of the tube bottle and the target gas has sufficient impact force, which is beneficial to saving production and manufacturing materials, thereby reducing production costs.
[0085] It should be noted that the above structure of the air blowing port 312 of the drying tube 3 can also be combined with the structure Figure 13 wherein a circulation hole 313 is provided at the top end of the drying tube 3 shown in, and the specific combination method is not particularly limited herein. Finally, it is at least necessary to ensure that the target gas blown towards the inner bottom of the tube bottle can enter the fluid channel.
[0086] Regarding the air inlet 311 of the drying tube 3, optionally, as Figure 2 and Figure 6 shown, the drying tube 3 and the seat cover 13 are integrally formed, so as to be beneficial to improving the sealing performance of the tube bottle drying instrument, thereby being beneficial to improving the drying efficiency and saving the gas consumption. Exemplarily, the air inlet 311 of the drying tube 3 is directly provided on the seat cover 13.
[0087] And / or, as Figure 6 and Figure 11As shown, in a specific embodiment, the aperture diameter of the air inlet 311 of the drying tube 3 is the same as that of the ventilation hole 31.
[0088] Alternatively, in another specific embodiment, as Figure 6 and Figure 12 shown, in the axial direction of the drying tube 3, the aperture diameter of the air inlet 311 of the drying tube 3 gradually decreases to the aperture diameter of the ventilation hole 31 along the blowing direction. In this way, under the guidance of the corresponding air inlet 311, the target gas in the air flow chamber 11 can quickly enter the ventilation hole 31.
[0089] The foregoing are only the preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, various modifications and changes can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the scope of the claims of the present application.
