Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of drying devices, and particularly relates to an air-drying device. Background Art
[0002] In the field of pharmaceutical synthesis, liquid may remain on the outer walls of devices such as reaction flasks. During the transfer process of the next reaction or treatment, it will drip onto other equipment, causing damage to experimental equipment, endangering the health of experimental personnel, resulting in environmental pollution, and affecting the accuracy of reaction results. Therefore, drying treatment is required.
[0003] Common drying treatment methods include natural air-drying, manual air-drying, or air-drying by setting a blower at the bottom, or setting a heating module to assist in drying. Natural air-drying takes a long time, and manual air-drying is cumbersome and inefficient, both of which cannot meet the requirements for the efficiency of automated production. Air-drying by setting a blower at the bottom easily causes liquid to drip onto the blower, thus damaging the equipment. Drying with a heating module has local overheating, which easily damages the reaction flask, and the local high temperature will also cause deviations in reaction results, ultimately leading to low production efficiency.
[0004] Therefore, there is an urgent need for a device that can adapt to the high production efficiency requirements of automated production conditions and can quickly dry. Summary of the Utility Model

[0031] The basic concept of this embodiment is to introduce gas from the top of the air - drying device, make the gas flow from top to bottom, take away the liquid on the surface of the air - drying object, and make the liquid flow away through the bottom of the air - drying device, and the gas is discharged from the bottom of the air - drying device.
[0032] This application provides a drying device. In this embodiment, for the specific structural diagram of the drying device, please refer to Figure 1 , Figure 2 . As Figure 1 , 2 shown, from the perspective of the external structure, the drying device provided by the embodiment of this application includes a blowing part 1, a drying part 2, a second filtering device 4, and a base 5.
[0033] The drying device includes a drying part 2 and a blowing part 1 that are fixedly connected to each other. The blowing part 1 is arranged on the top of the drying part 2. The drying part 2 includes a first drying port 21 for gas inflow, a second drying port 22 for gas discharge, and a drying channel 23 for performing the drying operation. The first drying port 21 is arranged on the top of the drying channel 23, and the second drying port 22 is arranged on the bottom of the drying channel 23;
[0034] The blowing part 1 includes a first blowing part 11, and the first blowing part 11 is arranged on the top of the drying part 2; the first blowing part 11 includes an air intake structure 111 for introducing gas and a blowing port 112 for blowing out gas. The air intake structure 111 is communicated with the blowing port 112, and the blowing port 112 is communicated with the first drying port 21.
[0035] The blowing part is arranged on the top of the drying part 2, which is convenient for introducing gas into the drying device and blowing the gas into the drying part 2 from top to bottom. The drying part 2 is used to perform the drying operation on the object to be dried.
[0036] Among them, the object to be dried refers to the object to be dried with residual liquid on the surface that is to be placed in the drying device. Exemplarily, in the field of pharmaceutical synthesis, the object to be dried can be experimental utensils such as reaction flasks and test tubes. In addition, the fixed connection method between the drying part 2 and the blowing part 1 can be a detachable fixed connection or an integral fixed connection. This application does not limit the method of fixing the object to be dried in the drying channel 23. Exemplarily, it can cooperate with the upper computer and other clamping mechanisms to complete the drying operation, clamp the object to be dried and transport it to the designated position in the drying channel 23. The designated position is a position suitable for drying, and the position suitable for drying can be comprehensively determined according to factors such as the size of the object to be dried and the gas flow rate.
[0037] Optionally, the process of performing the air-drying operation using the air-drying device according to the embodiments of the present application can be described as follows: After receiving the instruction issued by the host computer, the clamping mechanism clamps the object to be air-dried to a specified position in the air-drying channel 23. After receiving the signal, a compressed gas device, such as a compressed air device or a compressed nitrogen device, inputs gas through the inlet of the first channel 1111 of the air intake structure 111. The gas enters the air-drying channel 23 through the blowing part, moves downward in the air-drying channel 23 under the action of pressure, drives the liquid on the outer wall of the object to be air-dried to move downward, causes the liquid to drip or slide onto the first filtering device, and is discharged to the bottom of the air-drying device under the action of wind force; the gas passes through the pore of the bottom device and is discharged through the second filtering device to form a gas channel. According to the air-drying instruction issued by the host computer, after the compressed gas device receives the signal to stop air-drying, it stops admitting gas, and the clamping mechanism takes out the object to be air-dried, and the air-drying operation is completed.
[0038] Exemplarily, the host computer is the control center of the automated reaction flask air-drying device and its related equipment, and is used to respectively issue working instructions to corresponding components in a timely manner to achieve the coordinated control work among the components. For example, the host computer can adopt one or more of a PLC programmable controller, a micro-control computer, computer control software, etc.
[0039] Furthermore, the size of the air-drying part 2 can be selected according to the size of the object to be air-dried, with the criterion that it can accommodate the object to be air-dried and ensure that the object to be air-dried does not come into direct contact with the air-drying channel 23, so as to improve the adaptability of the air-drying device to objects to be air-dried of different sizes.
[0040] Furthermore, the blowing part can be combined with various devices to control the gas flow direction. Exemplarily, a one-way valve can be provided at the second air-drying port 22 to enable the gas to only flow into the air-drying channel; or the blowing part can be set as an air knife structure, so that the gas entering the air knife structure is blown out in the form of an air flow sheet, forming a high-strength and strong-impact air flow to blow into the air-drying channel 23; a high-pressure blowing pipeline can also be connected to the top of the blowing part, or compressed air can be used in cooperation with a nozzle, and the outlet of the nozzle is connected to the blowing part, so that the high-speed air flow enters the air-drying channel 23 from the first air-drying port 21.
[0041] The embodiment of the utility model is provided with an air-drying device in which gas flows from top to bottom, so that a high-speed, strong-impact airflow enters the air-drying channel from the first air-drying port, air-dries the air-drying object placed in the air-drying channel, and then discharges it from the bottom of the air-drying channel, which can take the residual liquid away from the surface of the air-drying object and collect it at the bottom of the air-drying device, which can shorten the air-drying time, enhance the effectiveness of air-drying, and increase the air-drying rate, thereby improving production efficiency; the air inlet is provided at the top of the air-drying portion, so that the equipment for inputting gas does not contact with the liquid, thereby avoiding damage to the equipment when encountering liquid, thereby improving the safety of the equipment; the embodiment of the utility model dries by blowing air, and does not introduce a heating module for drying, thereby avoiding uneven temperature and local overheating of the air-drying object at various places, thereby ensuring the safety of the next reaction operation; the top opening design facilitates the cooperation with a clamping mechanism such as a robotic arm to clamp the air-drying object to the air-drying portion for air-drying operation, thereby improving the tightness of the connection between the upper and lower processes in the automated process, and improving the degree of cooperation with other automated equipment, thereby improving automated production efficiency.
[0042] In some possible embodiments, the blowing part 1 also includes a second blowing part 12 arranged on the top of the first blowing part 11, the first blowing part 11 and the second blowing part 12 are fixedly connected, and a gap of a preset distance is provided between the top of the first blowing part 11 and the bottom of the second blowing part 12, and the gap is connected to the first air drying port 21 through the blowing port 112.
[0043] Preferably, the blowing part can adopt a wind knife structure, and the first blowing part 11 and the second blowing part 12 can be fixedly connected by bolts and nuts, etc., and a gap of a preset distance is arranged between the top of the first blowing part 11 and the bottom of the second blowing part 12. After the gas enters the gap through the air intake structure 111 of the first blowing part 11, it will be accelerated in the gap, and a low-pressure area will be generated at the center position of one side of the annular air knife, and a large amount of surrounding air will be introduced to form a conical annular airflow together with the high-pressure airflow, which will flow to the bottom of the first blowing part 11 and be blown into the first air drying port 21 through the blowing port 112.
[0044] Furthermore, the preset distance can be adjusted according to actual needs, and the gap can be enlarged by adding gaskets. If the preset distance is long, the gas flow rate is low and the air-drying time is long; if the preset distance is short, the gas flow rate is high and the air-drying time is short. It can be matched according to the requirements of air-drying efficiency.
[0045] In the embodiment of the present utility model, by utilizing the air knife structure, gas can enter the air drying channel from the first air drying port in a high-speed and directional state, enabling the high-speed air flow to fully blow off the liquid on the surface of the object to be air-dried, improving the cleanliness of the surface of the object to be air-dried, preventing the liquid from dripping on the surface of the object to be air-dried from causing environmental pollution, and also preventing the liquid from dripping during the next reaction operation, reducing the adverse impact on the accuracy of the reaction result, saving the time required for repeated operations caused by inaccurate reaction results, and improving production efficiency.
[0046] Please refer to Figure 3 , Figure 3 which is a cross-sectional view developed with A-A as the section on the basis of Figure 2 . As can be seen from Figure 3 , the internal structure of the air drying device is visible. As shown in Figure 3 , in some possible embodiments, an annular groove 113 is provided at the top of the first air blowing part 11, and the bottom surface of the second air blowing part 12 and the annular groove 113 form a gas diversion channel, and the annular groove 113 is communicated with the gap.
[0047] It should be noted that by providing the annular groove 113 at the top of the first air blowing part 11, after the gas enters the air blowing part from the air inlet structure 111, it can enter the annular groove 113, and then rotate at a high speed in the annular groove 113. The annular groove 113 plays a role in guiding and accelerating the gas.
[0048] In the embodiment of the present utility model, by providing an annular groove at the top of the first air blowing part, when the gas enters the air blowing part from the air inlet structure, it flows according to the shape of the provided annular groove, effectively forming the required high-speed rotating air flow, which can form a low-pressure area in the center of the air flow, helping to guide the gas to the gap, thereby forming a thin-sheet high-speed moving air flow, which can introduce the air flow into the air drying channel, improving the controllability of the air flow movement direction, enhancing the impact force of the air flow, thus improving the air drying efficiency, shortening the cleaning time, and improving the production efficiency.
[0049] Please continue to refer to Figure 3 , in some possible embodiments, the air inlet structure 111 further includes a first channel 1111 and a second channel 1112 that are communicated with each other. One end of the first channel 1111 is provided with an inlet for introducing gas, one end of the second channel 1112 is provided with an outlet for discharging gas, and the second channel 1112 is communicated with the annular groove 113 through the outlet.
[0050] In order to fully blow off the liquid on the surface of the object to be air-dried, it is required that the air flow entering the air-drying channel 23 be a high-speed and strong-impact air flow. The use of a Venturi structure can increase the gas flow velocity, thereby forming a high-speed air flow in the annular groove 113, better forming a low-pressure area in the center, and making the air flow velocity entering the air-drying channel faster and the impact stronger. Exemplarily, a compressed air blower can be used to input gas into the first channel 1111.
[0051] In the embodiment of the present utility model, by introducing compressed gas into the air intake structure, the gas can enter the blowing part along the path set by the air intake structure, thereby accelerating and forming a high-speed rotating air flow, and entering the air-drying channel from the first air-drying port in a high-speed and high-impact state, ensuring the impact of the air flow for air-drying the object to be air-dried, improving the reliability of the air-drying operation, air-drying the object to be air-dried through the air flow, improving the air-drying efficiency, being able to shorten the time used in the cleaning link, and improving the reaction production efficiency.
[0052] Please continue to refer to Figure 3 , in some possible embodiments, the channel diameter of the first channel 1111 is larger than the channel diameter of the second channel 1112.
[0053] Exemplarily, a Venturi structure is adopted in the air intake structure 111. Utilizing the Venturi effect, the gas flows from a large cross-section into a small cross-section, thereby achieving acceleration. The gas enters the air intake structure 111 from the first channel 1111. When entering the second channel 1112, since the channel diameter of the second channel 1112 is smaller than the channel diameter of the first channel 1111, the cross-section of the flow channel through which the fluid passes shrinks, and the gas velocity increases.
[0054] In the embodiment of the present utility model, by arranging a Venturi structure at the air intake structure, the fluid velocity is increased, which is beneficial to forming a high-speed air flow, enhancing the impact force on the liquid on the surface of the object to be air-dried, improving the water removal effect of the air-drying device, shortening the air-drying time, and improving the production efficiency.
[0055] Please continue to refer to Figure 3 , in some possible embodiments, the air intake structure 111 further includes a third channel 1113. One end of the third channel 1113 is communicated with the second channel 1112, the other end of the third channel 1113 is provided with an air outlet, the third channel 1113 is communicated with the annular groove 113 through the air outlet, and the included angle between the third channel 1113 and the second channel 1112 is 0 - 90°.
[0056] As shown in the figure, the first channel 1111 and the second channel 1112 are in parallel communication, and the included angle between the channels is 0°. In order to cooperate with other equipment, leave space for the connection activities and operations of the upstream and downstream processes, facilitate the realization of process automation and reduce costs, an additional third channel 1113 is provided.
[0057] Change the relative positions of the second channel 1112 and the first channel 1111 with respect to the air blowing port 112. The angle range can be 0 - 90°, as shown in the figure. Preferably, the angle can be selected as 90° or 0°, that is, the intake structure 111 is horizontally arranged without bending at the joints of each channel. It should be noted that the included angle between the third channel 1113 and the second channel 1112 referred to in this specification is the included angle between the gas flow directions when the gas is introduced. Therefore, when horizontally arranged, this included angle is 0 instead of 180°. If this included angle is set as an obtuse angle, the space occupied by the intake structure is enlarged, which is not conducive to the cooperative operation with other devices.
[0058] In the embodiment of the present utility model, by setting the third channel, the overall dimension layout of the intake structure is adjusted, leaving space for the operation and movement of other devices in other processes, optimizing the space layout, improving the rationality of space utilization, and reducing costs.
[0059] Please continue to refer to Figure 2 、 Figure 3 In some possible embodiments, the connecting surface between the top surface and the bottom surface of the first air blowing part 11 is an inclined surface.
[0060] The first connecting surface is an inclined surface connecting the top surface and the bottom surface of the first air blowing part 11. The top surface of the first air blowing part 11 is the side close to the bottom surface of the second air blowing part 12, and the bottom surface of the first air blowing part 11 is the side far from the bottom surface of the second air blowing part 12, causing the diameter of the air blowing port 112 to change, getting smaller as it gets closer to the first air drying port 21. Due to the Coanda effect, when the gas contacts the inclined surface, the flow direction changes, and the gas changes from high-speed rotation in the annular groove 113 to high-speed downward flow along the inclined surface. Therefore, the gas enters the first air drying port 21 of the air drying channel 23 through the air blowing port 112 of the first air blowing part 11 and flows at high speed from top to bottom in the air drying channel 23 to dry the object to be dried.
[0061] In the embodiment of the present utility model, by utilizing the Coanda principle, high-speed gas enters the air drying channel, which can blow away the liquid on the surface of the object to be dried. Without adding other heating devices, drying can be carried out, avoiding local overheating of the object to be dried and affecting the next reaction operation, saving the time required for repeated operations due to inaccurate reaction results, improving production efficiency, and also saving the cost of purchasing equipment.
[0062] Please continue to refer to Figure 3 In some possible embodiments, a first filtering device 3 is provided in the air drying channel 23, and filtering holes are provided on the first filtering device 3.
[0063] Optionally, the first filtering device 3 may be composed of at least one layer of filter plates. Exemplarily, the first filtering device may be provided with 1 layer, 2 layers, or 3 layers of filter plates. Further, when the gas entering the air-drying channel 23 performs an air-drying operation on the air-drying object, the liquid blown off from the surface of the air-drying object may drip or slide onto the first filtering device 3. The first filtering device 3 can delay the time for the liquid to fall to the bottom of the air-drying device, reduce the intensity of the collision between the liquid and the bottom of the air-drying device, reduce the occurrence of liquid splashing, and prevent the liquid from splashing out of the air-drying device and polluting the environment.
[0064] In the embodiment of the present utility model, by arranging the first filtering device in the air-drying channel, buffering when the liquid falls to the bottom of the air-drying device is achieved, the possibility of the liquid splashing out of the air-drying device is reduced, and the environmental cleanliness of the air-drying operation is ensured.
[0065] Please continue to refer to Figure 1 、 Figure 3 In some possible embodiments, a second filtering device 4 is sleeved on the outer surface of the air-drying part 2. The second filtering device 4 is provided with filtering holes, and the aperture of the filtering holes on the first filtering device 3 is smaller than the aperture of the filtering holes on the second filtering device 4.
[0066] Exemplarily, the aperture of the filtering holes of the first filtering device 3 is smaller than that of the second filtering device 4, which can intercept most of the liquid carried in the gas inside the air-drying channel 23 and make it flow naturally to the bottom of the air-drying device, preventing it from being carried out of the air-drying device by the gas.
[0067] In the embodiment of the present utility model, by arranging filtering devices inside and outside the air-drying device respectively, after filtering the gas in the air-drying device, the gas is discharged from the second air-drying port. By further filtering the gas through the second filtering device arranged outside the air-drying part, the content of the residual liquid in the gas can be further reduced, the cleanliness of the gas can be improved, and environmental pollution can be avoided.
[0068] When performing an air-drying operation using the air-drying device provided by the embodiment of the present application, the gas flow direction can be seen in Figure 4 The structure in the air-drying device provided by the embodiment of the present application is symmetrically arranged along the axis of symmetry of the air-drying channel. Therefore Figure 4 only a part of the structure symmetric along the axis of symmetry of the air-drying channel is shown, and the gas flow of the other part of the structure can be inferred by analogy.
[0069] Such as Figure 4As shown, gas enters the intake structure 111 from the inlet of the first channel 1111, reaches the annular groove 113 of the first blowing part 11 via the intake structure 111, rotates at high speed in the annular groove 113, and then moves from the gap along the inclined plane towards the blowing port 112 of the first blowing part 11. Then, the gas enters the air drying channel 23 through the first air drying port 21 of the air drying part 2, dries the object to be dried, and then the gas is filtered by the first filtering device 3 and discharged from the second air drying port 22. Finally, after being filtered again in the second filtering device 4, the gas is discharged from the air drying device, thus completing the drying of the object to be dried, the collection of the blown-off liquid, and the filtering of the gas after drying.
[0070] Since the gas blown into the air drying channel 23 is a gas flowing at high speed, and during the air drying operation, the gas leaves the air drying device through the second air drying port 22. At this time, the gas may carry a small amount of liquid taken away from the surface of the object to be dried. To avoid pollution, the technical solution of this application is set as follows:
[0071] In some possible embodiments, the air drying device is further provided with an outlet channel 24. The included angle between the outlet channel 24 and the air drying channel 23 is 10° - 120°. One end of the outlet channel 24 is communicated with the second air drying port 22, and the other end of the outlet channel 24 is communicated with the second filtering device 4.
[0072] In an ideal state, after the gas dries the object to be dried in the air drying channel 23, the liquid blown off the surface of the object to be dried after drying falls to the second air drying port 22. A liquid collection device can be set to collect it, or a diversion structure can be set to divert the liquid to other positions. However, due to the drive of the high-speed gas, some liquid may flow with the gas. By setting the outlet channel 24, the flow directions of the gas and the liquid are suddenly bent, which can effectively reduce the flow rates of the gas and the liquid, thereby retaining the gas and the liquid in the outlet pipe 24, or enabling the gas and the liquid to flow out of the outlet pipe 24 slowly after the speeds are reduced, further avoiding pollution.
[0073] In the embodiment of the present utility model, by setting the outlet pipe, the high-speed gas and liquid blown out of the air drying channel can be decelerated, so that some liquid can be blocked by the baffle and remain in the outlet pipe, and then drip to the bottom of the air drying device, reducing the possibility of the gas blown out of the air drying device carrying residual liquid and reducing the possibility of causing environmental pollution.
[0074] Implementing the technical solution of the present utility model has the following beneficial effects:
[0075] 1. In the embodiment of the present utility model, by providing an air-drying device with gas flowing from top to bottom, high-speed and strong-impact airflows enter the air-drying channel from the first air-drying port, air-dry the object to be air-dried placed in the air-drying channel, and then discharge from the bottom of the air-drying channel. This can carry the residual liquid away from the surface of the object to be air-dried and collect it at the bottom of the air-drying device, shortening the air-drying time, enhancing the effectiveness of air-drying, increasing the air-drying rate, and thus improving the production efficiency. The air inlet is arranged at the top of the air-drying part, so that the device for inputting gas does not come into contact with the liquid, avoiding damage to the device due to liquid contact and improving the safety of the device. In the embodiment of the present utility model, drying is carried out by blowing air, and no heating module is introduced for drying, avoiding uneven temperatures at various parts of the object to be air-dried and local overheating, and ensuring the safety of the next reaction operation.
[0076] 2.

[0077] 3. In the embodiment of the present utility model, by providing an annular groove at the top of the first blowing part, when gas enters the blowing part from the air inlet structure, it flows according to the shape of the set annular groove, effectively forming the required high-speed rotating airflow, capable of forming a low-pressure area in the center of the airflow, helping to guide the gas to the gap, thereby forming a thin-sheet high-speed moving airflow, which can introduce the airflow into the air-drying channel, improving the controllability of the airflow movement direction, enhancing the impact force of the airflow, thus improving the air-drying efficiency, shortening the cleaning time, and improving the production efficiency.
[0078] 4. In the embodiment of the present utility model, by introducing compressed gas into the air inlet structure, the gas can enter the blowing part along the path set by the air inlet structure, thereby accelerating and forming a high-speed rotating airflow, entering the air-drying channel from the first air-drying port in a high-speed and high-impact state, ensuring the impact force of the airflow for air-drying the object to be air-dried, improving the reliability of the air-drying operation, air-drying the object to be air-dried through the airflow, improving the air-drying efficiency, capable of shortening the time used in the cleaning link, and improving the reaction production efficiency.
[0079] 5. In the embodiment of the present utility model, by providing a Venturi structure at the air inlet structure, the fluid velocity is increased, which is beneficial to the formation of high-speed airflow, enhancing the impact force on the liquid on the surface of the object to be air-dried, improving the water removal effect of the air-drying device, shortening the air-drying time, and improving the production efficiency.
[0080] 6. In the embodiment of the present utility model, by setting the third channel, the overall dimensional layout of the air intake structure is adjusted, leaving space for the operation and movement of other equipment in other processes, optimizing the spatial layout, improving the rationality of space utilization, and reducing costs.
[0081] 7. In the embodiment of the present utility model, by utilizing the Coanda effect, high-speed gas enters the air drying channel, which can blow away the liquid on the surface of the object to be dried. Without adding other heating equipment, air drying is carried out, avoiding local overheating of the object to be dried, which may affect the next reaction operation, saving the time required for repeated operations due to inaccurate reaction results, improving production efficiency, and also saving the cost of purchasing equipment.
[0082] 8. In the embodiment of the present utility model, by setting the first filtering device in the air drying channel, buffering is achieved when the liquid falls to the bottom of the air drying device, reducing the possibility of liquid splashing out of the air drying device, and ensuring the environmental cleanliness of the air drying operation.
[0083] 9. In the embodiment of the present utility model, by respectively setting filtering devices inside and outside the air drying device, after filtering the gas in the air drying device, the gas is discharged from the second air drying outlet. The gas is further filtered by the second filtering device arranged outside the air drying part, which can further reduce the content of residual liquid in the gas, improve the cleanliness of the gas, and avoid environmental pollution.
[0084] 10. In the embodiment of the present utility model, by setting the outlet pipe, the high-speed gas and liquid blown out of the air drying channel can be decelerated, so that part of the liquid can be blocked by the baffle and remain in the outlet pipe, and then drip to the bottom of the air drying device, reducing the possibility of the gas blown out of the air drying device carrying residual liquid and reducing the possibility of environmental pollution.
