Description

Technical Field

[0001] The invention provides a glassware drying device, and particularly relates to the technical field of drying. Background Art

[0002] Glassware drying device, also known as "glass instrument airflow dryer", is mainly used for drying glassware in the laboratory. Its principle is to use heated airflow to blow hot air into the glassware to dry the glassware.

[0003] The utility model with authorization announcement number CN220689715U discloses a vessel drying device, which adds a vessel pre-placement plate on the upper surface of the top cover, and the surface of the vessel pre-placement plate is evenly provided with stepped truncated cones, which are nested on the outside of the vessel inverted tube through the tube through-hole, and the stepped truncated cones are provided with multiple circular steps, and the diameter of the steps is consistent with the diameter of the tube mouth of the commonly used glassware in the laboratory, so that the vessel can be stably inserted inverted on the outside of the steps. When in use, the vessels are pre-inserted inverted on the outside of the stepped truncated cone one by one, and then the vessel pre-placement plate is placed on the top cover. The placement process will not touch the vessel inverted tube, thus avoiding contamination of the inner wall of the vessel, and all the vessels can be quickly unloaded, thereby improving work efficiency. However, the above-mentioned drying device for utensils has some shortcomings when used: the above-mentioned drying device for utensils fails to limit and fix the test tube when used. When hot air blows towards the utensils, the utensils will shake due to the influence of the hot air. During the drying process, if the utensils are affected by external vibration, they will also shake. After the utensils shake, they will collide with the air outlet pipe, which may easily cause the utensils to touch the air outlet pipe and break. In addition, since the utensils lack restraint and fixation, when the inner wall of the utensils contacts the outer wall of the air outlet pipe, it will not only affect the air outlet effect of the air outlet pipe, thereby affecting the drying effect, but also if the outer wall of the air outlet pipe is not properly treated in the early stage, it will cause the inner wall of the utensils to be contaminated, affecting the subsequent use of the utensils.

[0015] Compared with the known prior art, the technical solution provided by the present invention has the following beneficial effects: The glassware drying device uses four restraining blocks and horizontal springs to stably fix each test tube on the outside of the corresponding small air duct, large air duct, and medium air duct, thereby preventing the hot air blown out of the dryer body from causing the test tube to shake, and also preventing the test tube from accidentally being subjected to external vibration during the drying process, thereby ensuring the stability of the test tube during the drying process, preventing the test tube from touching the air duct and breaking due to shaking during the drying process, and improving the safety of the test tube drying process; At the same time, the test tube is clamped and fixed, which can ensure that the test tube and the small air duct, the large air duct, and the medium air duct are respectively located on the same axis, which can prevent the test tube from tilting and causing the inner wall of the test tube to contact the outer wall of the small air duct, the large air duct, and the medium air duct.

In addition, the side air duct can blow hot air from the outside, so that the outer wall of the test tube can be evenly dried. By means of the connecting and docking mechanisms commonly provided in each air outlet duct and each small air duct, large air duct and medium air duct, each air duct can be controlled individually. Before the drying process, the experimenter manually separates the small air duct, large air duct and medium air duct where no test tube is placed from the corresponding air outlet duct. After the separation, the air outlet duct can be disconnected from the dryer body, thereby preventing hot air from being blown out from the part where no test tube is set, and making the hot air generated by the drying equipment concentratedly supplied to the air outlet duct with the test tube, so that the heat is effectively used to dry the test tube, thereby avoiding the waste of the hot air blown out from the dryer body due to ineffective utilization.

DETAILED DESCRIPTION

[0018] The present invention will be further described below in conjunction with the embodiments. Example

[0019] like Figures 1 to 5As shown, a glassware drying device includes a dryer body 1, and no less than four groups of combined pipes are connected and arranged on the top surface of the dryer body 1, each group of combined pipes consists of three air outlet pipes 11, and the three air outlet pipes 11 are respectively plugged with a small air duct 12, a large air duct 13, and a medium air duct 14, and the three air ducts of different sizes are provided with evenly distributed air outlet holes. When in use, glass test tubes of small, large, and medium sizes can be correspondingly set on the outside of the three; Note: The glass test tubes are all experimental test tubes, and their specifications and sizes are all existing standard sizes. The small air duct 12, the large air duct 13, and the medium air duct 14 have the same diameter as the air outlet pipe 11, and the three are tightly plugged with the air outlet pipe 11, and sealing rings are provided at the plugging parts of the three air ducts of different sizes and the air outlet pipe 11.

[0020] The top surface of the dryer body 1 is provided with a constrained rotation mechanism, which is composed of a constrained assembly and a rotating assembly, wherein the constrained assembly includes four ring-shaped plates 21 fixedly connected to the top surface of the dryer body 1, and the position of each ring-shaped plate 21 corresponds to the position of each group of combined pipes, and each ring-shaped plate 21 is composed of a plate body at the bottom and three circular rings at the top, and the plate body and the circular rings are fixedly connected, and the positions of the three circular rings at the top of each ring-shaped plate 21 correspond to the positions of the small air duct 12, the large air duct 13, and the medium air duct 14, respectively, and the sizes of the three circular rings also correspond to the three different The sizes of the air ducts are matched, and a constraint ring 22 is rotatably connected to the circular ring on the top of each ring plate body 21. A total of three constraint rings 22 are arranged on the corresponding ring plate body 21, and the inner diameter size of each constraint ring 22 is different, and the position of each constraint ring 22 corresponds to the position of the small air duct 12, the large air duct 13, and the medium air duct 14 respectively. Specifically, the inner diameter size of the constraint ring 22 corresponding to the small air duct 12, the large air duct 13, and the medium air duct 14 is larger than the outer diameter size of the three, and the centers of the three constraint rings 22 can allow large, medium, and small sized glassware to pass through.

[0021] The top surface of each constraint ring 22 is provided with four array grooves 23 evenly distributed in the circumferential direction, and the interiors of the four array grooves 23 are respectively slidably connected with constraint blocks 24, and the four constraint blocks 24 are respectively provided with inclined surfaces 241 and arc surfaces 242 on the sides close to each other, and the inclined surface 241 is located above the arc surface 242, and the surface of the inclined surface 241 is smoothed to reduce the friction with the glass test tube.

[0022] A rubber anti-skid pad is provided on the arc surface 242 to increase the friction force in contact with the glass test tube. A horizontal spring 25 is connected between each constraint block 24 and the groove surface of the corresponding array groove 23. One end of the horizontal spring 25 is fixedly connected to the outer wall of the constraint block 24, and the other end is fixedly connected to the groove surface of the array groove 23 away from the constraint block 24. The sizes of the array groove 23, constraint block 24 and horizontal spring 25 on each constraint ring 22 are different to adapt to large, medium and small sizes of glass test tubes, that is, the overall size specifications of the constraint assembly are compatible with the size specifications of the small air duct 12, the large air duct 13 and the medium air duct 14.

[0023] By providing constraint components of different sizes on the small air duct 12, the large air duct 13, and the medium air duct 14, test tubes of different specifications and sizes can be clamped and fixed appropriately, thereby improving the applicability of the constraint components and thus improving the overall practicality of the drying device.

[0024] Furthermore, if Figures 1 to 4 As shown, one side of the three air outlet ducts 11 is connected to a side air duct 111, each side air duct 111 is parallel to the corresponding air outlet duct 11, and the length of each side air duct 111 is equal to the length of the corresponding small air duct 12, large air duct 13, and medium air duct 14, and air outlet holes are evenly opened on the side air duct 111.

[0025] During use: the experimenter prepares the cleaned test tubes, and selects the corresponding small air duct 12, large air duct 13, and medium air duct 14 according to the large, medium, and small test tubes. For the convenience of explanation, in this embodiment, only the small air duct 12 is taken as an example to explain the relevant principles.

[0026] The experimenter puts the open end of the test tube downward onto the upper end of the corresponding small air duct 12. During the putting process, the open end of the test tube collides with the inclined surfaces 241 of the four constraint blocks 24 around the top of the small air duct 12. As the test tube continues to be put downward onto the outside of the small air duct 12, the four constraint blocks 24 move horizontally away from the center of the constraint ring 22 along the trajectory of the array slot 23. The movement of the four constraint blocks 24 causes the four horizontal springs 25 to be compressed at the same time.

[0027] When the test tube continues to move downward until the outer wall of the test tube corresponds to the position of the four arc surfaces 242 on the four constraint blocks 24, the arc surfaces 242 of the four constraint blocks 24 are tightly fitted with the outer wall of the test tube under the action of the rebound force of the four horizontal springs 25. Then the experimenter continues to move the test tube downward until the bottom of the inner wall of the inverted test tube located above tends to contact the top surface of the small air duct 12, and then stops further installation of the test tube. In other words, when the experimenter is putting on the test tube, there is no need to make the bottom of the inner wall of the test tube contact the top surface of the small air duct 12, and the downward opening part of the test tube does not contact the lowermost end of the small air duct 12.

[0028] When the test tube is placed downwardly on the outside of the small air duct 12, the test tube is automatically restrained and fixed under the action of the four restraining blocks 24, the arc surface 242 and the four horizontal springs 25. Subsequently, according to the above steps, the test tubes of corresponding sizes can be placed on the outside of the corresponding large air duct 13 and the medium air duct 14 in sequence, and the corresponding test tubes can be fixed by the corresponding restraining blocks 24 on the large air duct 13 and the medium air duct 14. Until all the test tubes to be dried are placed on the outside of the small air duct 12, the large air duct 13 and the medium air duct 14.

[0029] Then, the experimenter starts the dryer body 1, causing the hot air to blow upward from each air outlet duct 11 and blow into the corresponding small air duct 12, large air duct 13, and medium air duct 14, so that the hot air blows from the air outlet holes on the three air ducts to the inside of the test tube, thereby drying the inner wall of the test tube. When the test tube is dried, the experimenter can remove the test tube one by one.

[0030] Therefore, when the experimenters put the test tubes into the small air duct 12, the large air duct 13, and the medium air duct 14, the four restraint blocks 24 and the horizontal spring 25 and other components can be used to stably fix each test tube on the corresponding small air duct 12, the large air duct 13, and the medium air duct 14. This can prevent the hot air blown out by the dryer body 1 from causing the test tubes to shake. It can also prevent the test tubes from accidentally being subjected to external vibration forces during the drying process, thereby ensuring the stability of the test tubes during the drying process, and effectively preventing the test tubes from breaking due to hitting the air ducts during the drying process, thereby improving the safety of the test tube drying process.

[0031] At the same time, clamping and fixing the test tube can ensure that the test tube and the small air duct 12, the large air duct 13, and the medium air duct 14 are respectively located on the same axis, which can prevent the test tube from tilting and causing the inner wall of the test tube to contact the outer walls of the small air duct 12, the large air duct 13, and the medium air duct 14. This not only facilitates the hot air blown out of the air outlet holes on the three to contact the inner wall of the test tube evenly, but also prevents the three from contacting the inner wall of the test tube, thereby avoiding secondary pollution to the inner wall of the test tube and ensuring the hygiene of the drying process.

[0032] In addition, the hot air blown out by the air outlet duct 11 will also be blown out through the side air duct 111 connected thereto, and the hot air blown out by the side air duct 111 will also be blown onto the outer wall of the test tube, drying the outer wall of the test tube with hot air, thereby cooperating with the internal hot air blowing, and simultaneously drying the inner and outer walls of the test tube with hot air, thereby improving the overall drying efficiency of the test tube. Example

[0033] This embodiment is based on the design of the first embodiment, and the glassware drying device further includes a rotating component, such as Figure 1 , Figures 6 to 9 As shown, the rotating assembly includes a driving motor 31 fixedly mounted at the center of the top surface of the dryer body 1, and the driving motor 31 can be started and shut down by an external controller.

[0034] A central gear 32 is fixedly connected to the output shaft at the top of the drive motor 31. A bevel gear 33 is rotatably connected to the outer side of an air outlet pipe 11 closest to the drive motor 31 in each group of combined pipes. The teeth on the central gear 32 mesh with the teeth on the four bevel gears 33. There are four bevel gears 33 in total. A top rod 331 is fixedly connected to one side of the top surface of each bevel gear 33. A synchronous wheel 34 is fixedly connected to the outer ring surface of the constraint ring 22 on the side of each ring plate body 21 closest to the drive motor 31. The constraint ring 22 is correspondingly arranged above the air outlet pipe 11 closest to the drive motor 31. Therefore, the position of the constraint ring 22 is located directly above the bevel gear 33. The top of each top rod 331 is fixedly connected to the bottom of the corresponding synchronous wheel 34. The constraint ring 22 arranged in the middle part of the ring plate body 21 2, two synchronous wheels 2 35 are fixedly connected to the outer ring surface, and the two synchronous wheels 2 35 are distributed up and down, and a synchronous belt 1 36 is transmission-connected between the synchronous wheel 2 35 located at the upper layer and the synchronous wheel 1 34, and a synchronous wheel 3 37 is fixedly connected to the outer ring surface of the constraint ring 22 of the outermost side of the ring plate body 21, and a synchronous belt 2 38 is transmission-connected between the synchronous wheel 37 and the synchronous wheel 2 35 located at the lower layer, and the central axes of the two synchronous wheels 2 35 coincide with each other, and the central axes of the synchronous wheel 1 34 and the synchronous wheel 3 37 are parallel to the central axes of the two synchronous wheels 2 35.

[0035] During use: During the test tube drying process described in the previous embodiment, the experimenter can also start the drive motor 31, and drive the central gear 32 to rotate through the output shaft of the drive motor 31. As the central gear 32 rotates, the four beveled gears 33 meshing with it are driven to rotate in the opposite direction, and then the corresponding top rods 331 on the four beveled gears 33 are used to drive the constraint ring 22 fixedly connected to the top rod 331 on the ring plate body 21 to rotate synchronously. As the constraint ring 22 rotates, the upper synchronous wheel 2 35 located in the middle part of the ring plate body 21 is driven to rotate synchronously through the synchronous wheel 1 34 and the synchronous belt 1 36, thereby driving the constraint ring 22 fixedly connected to the synchronous wheel 2 35 to rotate synchronously. As the constraint ring 22 fixedly connected to the synchronous wheel 2 35 rotates, the constraint ring 22 fixedly connected to the synchronous wheel 3 37 is driven to rotate synchronously through the lower synchronous wheel 2 35 and the synchronous belt 2 38.

[0036] In this way, after the driving motor 31 is started, the cooperation of the above components can drive each constraint ring 22 to rotate synchronously, and each constraint ring 22 has a test tube clamped and fixed by the constraint block 24, and the constraint block 24 clamps and drives each test tube to rotate simultaneously.

[0037] Therefore, in the process of drying each test tube, through the cooperation of the driving motor 31, the synchronous wheel 1 34, the synchronous wheel 2 35, the synchronous wheel 3 37 and other components, each test tube can be driven to receive the blowing of hot air in a continuously rotating state, so that the hot air can contact the inside of the test tube more fully and evenly, thereby improving the drying efficiency and uniformity of the test tube, and in conjunction with the side air duct 111 to blow out hot air from the outside, the outer wall of the test tube can also be evenly dried. Example

[0038] This embodiment is based on the first embodiment or the second embodiment, and further includes a docking connection mechanism commonly provided in each air outlet pipe 11 and on the small air pipe 12, the large air pipe 13, and the medium air pipe 14, such as Figure 10 to Figure 11As shown, the docking connection mechanism includes a pressure plate 41 fixedly connected to the inner wall of the lower end of the small air duct 12, the large air duct 13, and the medium air duct 14, respectively. The inner wall of each air outlet pipe 11 is fixedly connected to a hole plate 42, and the inner wall of each air outlet pipe 11 and located above the hole plate 42 are fixedly connected to a ventilation ring 45, and the top surface of the hole plate 42 is fixedly connected to a vertical spring 43, and the end of the vertical spring 43 away from the hole plate 42 is fixedly connected to a sealing ball 44, and the diameter of the sealing ball 44 is adapted to the diameter of the inner ring of the ventilation ring 45. Specifically, when the small air duct 12, the large air duct 13, and the medium air duct 14 are connected to the corresponding air outlet pipe 1 When tight plugging is achieved, the bottom surface of the pressing plate 41 presses against the top surface of the sealing ball 44, and a gap is left between the sealing ball 44 and the inner ring of the ventilation ring 45. At this time, the air outlet pipe 11 is connected with the corresponding small air duct 12, large air duct 13, and medium air duct 14; and at this time, the vertical spring 43 is in a compressed state, and the rebound force of the vertical spring 43 is less than the friction force of the tight plugging between the air outlet pipe 11 and the corresponding air outlet pipe 11, large air duct 13, and medium air duct 14, that is, the rebound force of the vertical spring 43 will not cause the corresponding air outlet pipe 11, large air duct 13, and medium air duct 14 to automatically separate from the corresponding air outlet pipe 11. The pressure plate 41 is composed of an L-shaped plate body and a disc fixedly connected to the bottom of the L-shaped plate body. The disc is provided with evenly distributed through holes for the air flow blown out of the air outlet duct 11 to pass through. The sealing ball 44 is made of rubber material to ensure the sealing performance of the outer surface of the sealing ball 44 and the inner ring surface of the ventilation ring 45.

[0039] Taking into account that the test tubes that need to be dried each time may not be fully covered with the small air duct 12, the large air duct 13, and the medium air duct 14, the experimenter can manually select the corresponding number of small air ducts 12, large air ducts 13, and medium air ducts 14 for installation, and manually separate the small air ducts 12, large air ducts 13, and medium air ducts 14 that do not need to be covered with test tubes from the air outlet duct 11. After the small air duct 12, large air duct 13, and medium air duct 14 are separated from the air outlet duct 11, the air outlet duct 11 is still connected to the inside of the dryer body 1 at this time, but because the sealing ball 44 and the vertical spring 43 are not compressed by the pressure plate 41, the sealing ball 44 will block the ventilation ring 45, so that hot air will not be blown out from the air outlet duct 11 where the air duct is not installed, so as to prevent excessive waste of hot air blown out when the dryer body 1 is started.

[0040] When in use: when the test tube is set and the dryer body 1 is not started, if some of the small air ducts 12, large air ducts 13, and medium air ducts 14 are not covered with test tubes, the staff can pull out these small air ducts 12, large air ducts 13, and medium air ducts 14 one by one from the corresponding air outlet ducts 11. As the small air ducts 12, large air ducts 13, and medium air ducts 14 are pulled out from the inside of the air outlet duct 11, the corresponding pressing plates 41 will be driven to move away from the air outlet duct 11 synchronously, and at the same time, the disc at the bottom of the pressing plate 41 will no longer press the sealing ball 44, so that the sealing ball 44 will automatically block the inner ring of the ventilation ring 45 under the rebound force of the vertical spring 43. At this time, the dryer body 1 and the air outlet duct 11 are no longer connected under the blocking effect of the sealing ball 44, so that the air outlet duct 11 and the side air duct 111 will not continue to blow out hot air.

[0041] Therefore, by means of the connecting and docking mechanisms commonly provided inside each air outlet duct 11 and each small air duct 12, large air duct 13, and medium air duct 14, before the drying process, the experimenter manually separates some of the small air ducts 12, large air ducts 13, and medium air ducts 14 from the corresponding air outlet ducts 11. After the separation, the air outlet duct 11 can be disconnected from the dryer body 1, thereby preventing hot air from being blown out from the portion where the test tube is not mounted, and making the hot air generated by the drying equipment concentratedly supplied to the air outlet duct 11 mounted with the test tube, so that the heat is effectively used to dry the test tube, thereby avoiding the waste of the hot air blown out from the dryer body 1 due to ineffective utilization.

[0042] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. Such modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
