Description

Technical Field

[0001] This application relates to a volumetric flask drying apparatus. Background Technology

[0002] Volumetric flasks are used in pharmacokinetic analysis experiments to prepare standard solutions and accurate dilution solutions directly, as well as to prepare sample solutions.

[0003] Because volumetric flasks have narrow mouths and wide bottoms, they are difficult to dry quickly after washing. To dry them quickly, operators need to invert the flasks and use a blower to blow air into the mouth and outwards from the body. This method is not only inefficient but also time-consuming and labor-intensive. Drying a large number of volumetric flasks would take even longer and cannot meet the requirements of experiments. There is an urgent need for a volumetric flask drying device to solve the above problems. Summary of the Invention

[0004] To overcome the shortcomings of the prior art, this application discloses a volumetric flask drying device.

[0005] To achieve the above objectives, the technical solution adopted in this application is: a volumetric flask drying device, including a drying box and a hinged flip-top lid mounted on the top of the drying box, wherein a base plate is provided on the inner wall of the middle part of the drying box, and a bottle body fixing mechanism and an inner bottle drying mechanism are provided on the base plate.

[0006] The bottle body fixing mechanism includes a platform mounted on the base plate, and several bottle body clamps for clamping the upper part of the volumetric bottle are arranged inside the platform along its direction.

[0007] The bottle drying mechanism includes several bottle neck mounting seats arranged on the upper part of the base plate in correspondence with several bottle body clamps. Above the several bottle neck mounting seats are air knife tubes that can enter the volumetric flask. Several air ducts are connected to the first hot air system through a pipe splitter.

[0008] The bottom of the flip-top lid is provided with an external bottle drying mechanism, which includes a drying chamber located at the bottom of the flip-top lid. The bottom of the drying chamber is connected to several blower heads corresponding to the bottle clamps. The drying chamber is connected to a second hot air system through a corrugated pipe.

[0009] In one embodiment of this utility model, the drying box has an open portion extending from the top to the front, and two electric push rods are hinged between the flip-top lid and the open portion.

[0010] In one embodiment of this utility model, a plurality of water channels are formed on the upper surface of the substrate, a drainage channel communicating with the plurality of water channels is provided on one side of the substrate, and a drainage hole communicating with the drainage channel is provided on the side wall of the drying oven.

[0011] As one embodiment of this utility model, the bottle clamp includes a rectangular block, and the interior of the rectangular block has a contoured hollow groove that extends to the platform surface and is adapted to the upper part of the volumetric bottle. The upper sides of the contoured hollow groove are provided with elastic pressure balls for pressing down the bottom of the volumetric bottle together.

[0012] More preferably, the rectangular block has clearance notches on both sides that communicate with the contoured hollow groove to facilitate the handling of containers.

[0013] A further preferred embodiment is that the inner wall of the contoured hollow groove is uniformly provided with a number of raised points that allow the bottle body to detach from it.

[0014] In one embodiment of this utility model, several raised strips are arranged in a circular array above the bottle neck overlap seat, and oblique grooves are respectively formed between every two raised strips on the side wall of the bottle neck overlap seat.

[0033] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0034] In the description of this application, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around", etc., which indicate orientation or positional relationship, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the component or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. Example

[0035] To address the shortcomings of existing technologies that lack a single device for simultaneously drying multiple volumetric flasks both internally and externally, forcing researchers to rely on natural air drying or the use of a blower, this paper refers to... Figure 1 and Figure 3 As shown, this application provides a volumetric flask drying device, which includes a drying chamber 10 and a flip-top cover 20 hinged above the drying chamber 10. Specifically, the flip-top cover 20 can be automatically controlled. The drying chamber 10 has an open portion extending from the top to the front. Two electric push rods 21 are hinged between the flip-top cover 20 and the open portion. Driven by the two electric push rods 21, the flip-top cover 20 can automatically close or open the open portion. When the open portion is open, the operator can take or put away the volumetric flask. When the open portion is closed, the drying work can be carried out.

[0036] A base plate 11 is provided on the inner wall of the middle part of the drying oven 10. A bottle body fixing mechanism 30 and an in-bottle drying mechanism 40 are provided on the base plate 11. The bottle body fixing mechanism 30 includes a frame 31 mounted on the base plate 11. Several bottle body clamps 32 for clamping the upper part of the volumetric bottle are arranged inside the frame 31 along its direction.

[0037] In practice, the operator needs to place several cleaned volumetric flasks into the flask clamps 32 and fix each volumetric flask in place by the flask clamps 32.

[0038] The bottle drying mechanism 40 includes several bottle neck mounting seats 41 arranged on the substrate 11 in correspondence with several bottle body clamps 32. Above the several bottle neck mounting seats 41, there are air knife pipes 42 that can enter the volumetric bottle. Several air ducts are connected to the first hot air system 44 through a pipe splitter 43.

[0039] When the above-mentioned volumetric flasks are fixed, their mouths will be connected to the mouth connection seat 41, and the air knife tubes 42 are inserted into the inside of the volumetric flasks by default. When the first hot air system 44 delivers hot air to each air knife tube 42 through the pipe distributor 43, the air knife tubes 42 will blow out hot air to dry the inside of the volumetric flasks.

[0040] The bottom of the flip-top lid 20 is provided with an external bottle drying mechanism 50. The external bottle drying mechanism 50 includes a drying chamber 51 located at the bottom of the flip-top lid 20. The bottom of the drying chamber 51 is connected to several blower heads 52 corresponding to the bottle clamps 32. The drying chamber 51 is connected to a second hot air system 54 through a corrugated pipe 53.

[0041] While the first hot air system 44 outputs hot air through several air knife tubes 42 to dry the inside of several volumetric flasks, the second hot air system 54 outputs hot air into the drying chamber 51 and blows it downwards through several blower heads 52. When the hot air blows to the surface of each volumetric flask, it can remove the moisture attached to its surface, thereby drying its outer surface.

[0042] refer to Figure 2 As shown, considering that the drying oven 10 will generate wastewater during the drying process, this application forms a plurality of water channels 111 on the upper surface of the substrate 11. A drainage channel 112 communicating with the plurality of water channels 111 is provided on one side of the substrate 11. A drainage hole 113 communicating with the drainage channel 112 is provided on the side wall of the drying oven 10. During the drying process, the wastewater falling on the substrate 11 will enter the drainage channel 112 along the water channels 111 and be discharged through the drainage hole 113. It should be further noted that, in order to prevent the wastewater from falling directly into the laboratory floor, the operator can place a water receiving device (not shown in this application) corresponding to the drainage hole 113 on the laboratory floor.

[0043] refer to Figure 4 As shown, in one embodiment, the bottle clamp 32 of this application includes a rectangular block 321. The rectangular block 321 has a contoured hollow groove 3211 extending to the platform 31 and adapted to the upper part of the volumetric flask. The upper sides of the contoured hollow groove 3211 are provided with elastic pressure balls 322 for pressing the bottom of the volumetric flask together. When fixing the volumetric flask, the operator inverts the volumetric flask and presses the two elastic pressure balls 322 into the contoured hollow groove 3211 and moves it downward. When the volumetric flask is completely placed inside the contoured hollow groove 3211, the two elastic pressure balls 322 will rebound and abut against the bottom wall of the volumetric flask. When the operator removes the volumetric flask from the contoured hollow groove 3211, it can be moved upward by pulling the volumetric flask while pressing the two elastic pressure balls 322 into the contoured hollow groove 3211.

[0044] Continue to refer to Figure 4 As shown, based on the above implementation scheme, this application also provides clearance notches 3212 on both sides of the rectangular block 321, which communicate with the contoured hollow groove 3211 to facilitate the handling of container bottles. When the dried volumetric bottle is picked up, the operator's fingers (corresponding to the middle finger and thumb) can pass through the two clearance notches 3212 to directly take it out, which is more convenient to use.

[0045] Continue to refer to Figure 4 As shown, based on the above implementation scheme, considering that the contact between the volumetric flask and the contoured hollow groove 3211 will cause poor drying of the outer surface of the volumetric flask, this application provides a number of raised points 32111 evenly on the inner wall of the contoured hollow groove 3211 to allow the flask body to separate from it. In this way, the hot air blown out by the blower head 52 can smoothly contact the outer surface of the volumetric flask body, and the drying effect is greatly enhanced.

[0046] refer to Figure 5 As shown, in order to enable the water or water vapor blown out by the air knife tube 42 to be quickly discharged onto the bottle mouth connector 41, this application provides several protruding strips 411 arranged in a ring above the bottle mouth connector 41. The side wall of the bottle mouth connector 41 is provided with inclined grooves 412 between every two protruding strips 411. In actual use, the water or water vapor blown out by the air knife tube 42 will flow into the surface of the substrate 11 along the inclined grooves 412.

[0047] refer to Figure 3 As shown, specifically, the first hot air system 44 of this application includes a first heater 441 and a first booster pump 442. The first heater 441 is installed inside the drying chamber 10, and the first booster pump 442 is connected to the exhaust port of the first heater 441. The main pipe of the distributor 43 is connected to the first booster pump 442. When drying the inside of the volumetric flask, the first heater 441 and the first booster pump 442 are started to work. The hot air from the product of the first heater 441 is delivered by the first booster pump 442 to several air knife pipes 42 and blown out.

[0048] The second hot air system 54 includes a second heater 541 and a second booster pump 442. The second heater 541 is located inside the drying chamber 10, and the second booster pump 442 is connected to the exhaust port of the second heater 541. One end of the bellows 53 is connected to the second booster pump 442. When drying the inside of the volumetric flask, the second heater 541 and the second booster pump 442 are started. The hot air from the product of the second heater 541 is delivered to the drying chamber 51 by the second booster pump 442 and blown out through several air knife pipes 42.

[0049] refer to Figure 1 and Figure 3As shown, in order to facilitate operators to observe the working conditions inside the drying oven 10 in real time, this application has installed a viewing window 12 on at least one side of the drying oven 10.
