Description

Technical Field

[0001] This invention relates to the field of drying tank technology, specifically a vertical lifting drying tank. Background Technology

[0002] A drying tank is a device or apparatus used to dry objects. It is widely used in industrial production, manufacturing, and laboratories. A drying tank typically contains air knives, which are key components for achieving the drying function. An air knife is usually a long, narrow device with uniformly spaced air holes, capable of blowing out a high-speed, uniform airflow to quickly remove moisture from the surface of the object.

[0003] Existing drying equipment primarily uses fixed air knives or chain-driven air knives to dry workpieces. However, both methods have drawbacks. Fixed air knife drying is slow when dealing with larger workpieces, while the chain-driven air knife is prone to bending due to the lack of protective devices when moving with it. Furthermore, existing air knives typically use direct blowing when drying workpieces. If water droplets remain on the workpiece, direct blowing can cause splashing. If these splashes land on the non-waterproof mechanical parts of the drying tank, it can affect the overall use of the drying tank. Summary of the Invention

[0010] Preferably, the hanging mechanism includes a hanging frame disposed inside the tank, an RFID reader is mounted on the hanging frame, mounting plates are fixedly connected to both sides of the hanging frame, multiple clamps are mounted on the mounting plates, the multiple clamps jointly hold the product, and limit plates are provided on both sides of the mounting plates.

[0011] Preferably, a liquid storage tank is fixedly connected to both sides of the hanging frame, and an air inlet box is installed between the two liquid storage tanks. An air inlet is connected to the bottom of the air inlet box. A rotating rod is rotatably installed inside the air inlet. Both ends of the rotating rod extend to the outside of the air inlet. Multiple fan blades are fixedly connected to the outer wall of the rotating rod. Multiple spray pipes are installed on the multiple fan blades. The multiple spray pipes are connected to the inside of the rotating rod. Each of the multiple spray pipes has a bottom hole and a top hole. A blocking member is slidably connected inside the spray pipe. A tension spring is installed at the bottom of the blocking member. The end of the tension spring away from the blocking member is fixedly connected to the inner wall of the spray pipe. A limiting member is installed inside the spray pipe.

[0012] Preferably, the liquid storage tank has a pluggable filling port, a covering ring is fixedly connected to the outer wall of the liquid storage tank, an inlet pipe is connected to the covering ring, the end of the inlet pipe away from the covering ring is connected to the interior of the liquid storage tank, the end of the rotating rod is rotatably connected to the covering ring, and the end of the rotating rod has multiple through holes.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. Through the design of the lead screw and other mechanisms, when the lead screw rotates, it drives the air knife to move up and down to dry the surface of the product. Compared with the traditional chain structure, the lead screw is simpler, has a longer service life, and drives the air knife to move more smoothly than the traditional chain. In addition, through the tank chain with built-in air pipe, the tank chain protects the air pipe when the air knife moves up and down, preventing it from being jammed due to excessive bending. Furthermore, the entire tank is completely sealed, so water droplets cannot splash outside the tank during the drying process. At the same time, the operation status of the entire tank can be monitored in real time through the setting of photoelectric sensors.

[0015] 2. Through the design of the air inlet box and air outlet, the air knife briefly pauses on the side of the air inlet box before drying the product from top to bottom. During this time, the nitrogen gas blown out by the air knife is guided by the air inlet box and air outlet to blow onto the surface of the product from top to bottom. If there are water droplets on the surface of the product, the airflow blowing from top to bottom is in the same direction as the gravity flow of the water droplets, which can promote the moisture to flow down from the surface of the workpiece more quickly, accelerating the drying process. At the same time as blowing nitrogen vertically downward, the entire fan blade will also mix a small amount of isopropanol into the nitrogen. After mixing with the nitrogen, the isopropanol molecules will be dispersed in the nitrogen, increasing the contact area with the air and further increasing its evaporation rate, promoting the evaporation of surrounding moisture more quickly, thereby accelerating the overall drying speed and improving the efficiency of the subsequent horizontal blowing of the air knife on the product surface.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Example 1: Please refer to Figure 1 - Figure 10 A vertical lifting drying trough includes a trough body 4. A cover-opening cylinder 29 is fixedly connected to the side wall of the trough body 4. A cylinder connecting seat 28 is slidably connected to the cover-opening cylinder 29. A shaft pin 30 is installed on the cylinder connecting seat 28. Two connecting pieces 27 are rotatably connected to the shaft pin 30. A connecting rod 26 is installed on the outer side wall of the two connecting pieces 27. A cover plate 25 is installed on the connecting rod 26. Multiple hinges 24 are fixedly connected to the cover plate 25. The other end of the multiple hinges 24 is fixed to the outer side wall of the trough body 4. A lifting mechanism is provided on the trough body 4. The lifting mechanism includes a fixed plate 10 set inside the trough body 4. Guide rails 11 are opened on both sides of the fixed plate 10. A lead screw 12 is rotatably connected to the outer side wall of the fixed plate 10. An air knife mounting bracket 13 is threaded onto the outer side wall of the lead screw 12. A synchronous pulley 15 is fixedly connected to the lower end of the fixed plate 10. A synchronous belt 16 is sleeved on the synchronous pulley 15.

[0029] A base plate 31 is installed on the side wall of the tank 4. A servo motor 32 is fixedly connected to the base plate 31. A guide wheel is provided at the output end of the servo motor 32. The end of the synchronous belt 16 away from the synchronous pulley 15 is sleeved on the guide wheel. A tension wheel assembly 34 is provided on the outer side wall of the base plate 31. The tension wheel assembly 34 is in contact with the synchronous belt 16.

[0030] The guide rail 11 has a sliding block 20 inside, and an air knife 22 is provided on the slide block 20. Air inlet pipe connectors 21 are fixedly connected to both sides of the air knife 22. Tank chains 35 are installed on both sides of the fixing plate 10. Air pipes are provided inside the tank chains 35 and are connected to the air inlet pipe connectors 21.

[0031] The tank body 4 is fixedly connected to a hanger support plate 36, and the tank body 4 is rotatably connected to a linear bearing 37. The bottom of the tank body 4 is provided with a movable guide rod 33, the bottom of the movable guide rod 33 is provided with a cylinder plate 18, a cylinder 17 is fixedly connected to the cylinder plate 18, a waterproof cover 14 is provided on the cylinder 17, and the hanger support plate 36 is provided on the cylinder 17.

[0032] Multiple photoelectric sensors 19 are installed on both sides of the tank 4, and a hanging mechanism is installed on the tank 4.

[0033] The mounting mechanism includes a mounting frame 5 set inside the groove 4, an RFID reader 6 installed on the mounting frame 5, mounting plates 9 fixedly connected to both sides of the mounting frame 5, multiple clamps 7 installed on the mounting plates 9, the multiple clamps 7 together clamp the product 8, and limit plates 23 are set on both sides of the mounting plates 9.

[0034] In this embodiment, during use, the cover-opening cylinder 29 can be activated to push the cylinder connecting seat 28 to move, thereby causing the two connecting pieces 27 to flip to both sides. The cover plate 25 is opened via the connecting rod 26. After the cover plate 25 is opened, the hanging frame 5 holding the product 8 can be placed into the slot 4 until the bottom of the hanging frame 5 contacts the hanging support plate 36. After the hanging frame 5 is placed, the cover plate 25 is closed. Finally, the operator can turn on the servo motor 32, causing it to drive the lead screw 12 to rotate via the synchronous pulley 15 and synchronous belt 16. When the lead screw 12 rotates, it causes the air knife mounting bracket 13 to move the air knife 22 up and down. When the air knife 22 moves up and down, the photoelectric sensor 19 limits the vertical movement of the air knife 22. The air pipe is connected to the air inlet pipe connector 21 through the protection of the tank chain 35 to supply nitrogen to the inside of the air knife 22. When the air knife 22 moves up and down to blow out nitrogen, it can quickly dry the water on the surface of the product 8. While the air knife 22 moves up and down to blow out nitrogen to dry the water on the surface of the product 8, the operator can also open the cylinder 17 to push the cylinder plate 18 and the guide rod 33 to move, thereby changing the position of the hanger frame 5 through the hanger support plate 36, increasing the blowing length and area on the hanger frame 5, so that all the water carried in the tank 4 is dried. The waterproof cover 14 protects the linear bearing 37. After the water on the surface of the product 8 is dried, the cover opening cylinder 29 can be activated to repeat the above steps, open the cover plate 25, and take out the hanger frame 5.

[0035] Example 2: Please refer to Figure 1 - Figure 10 This embodiment further describes Example 1. Liquid storage tanks 38 are fixedly connected to both sides of the hanging frame 5. An air inlet box 3 is installed between the two liquid storage tanks 38. An air inlet 40 is connected to the bottom of the air inlet box 3. A rotating rod 42 is rotatably installed inside the air inlet 40. Both ends of the rotating rod 42 extend to the outside of the air inlet 40. Multiple fan blades 43 are fixedly connected to the outer wall of the rotating rod 42. Multiple spray pipes 46 are installed on the multiple fan blades 43. The multiple spray pipes 46 are all connected to the inside of the rotating rod 42. Bottom holes 41 and top holes 47 are respectively opened on the multiple spray pipes 46. A blocking member 49 is slidably connected inside the spray pipe 46. A tension spring 48 is installed at the bottom of the blocking member 49. The end of the tension spring 48 away from the blocking member 49 is fixedly connected to the inner wall of the spray pipe 46. A limiting member 1 is installed inside the spray pipe 46.

[0036] The liquid storage tank 38 is provided with a pluggable filling port 39. A covering ring 44 is fixedly connected to the outer wall of the liquid storage tank 38. An inlet pipe 2 is connected to the covering ring 44. The end of the inlet pipe 2 away from the covering ring 44 is connected to the interior of the liquid storage tank 38. The end of the rotating rod 42 is rotatably connected to the covering ring 44. Multiple through holes 45 are provided at the end of the rotating rod 42.

[0037] In this embodiment, before the air knife 22 dries the product 8 from top to bottom according to the above principle, the air knife 22 will briefly stop on the front side of the air inlet box 3. At this time, the nitrogen gas blown out by the air knife 22 will enter the air outlet 40 through the air inlet box 3 (refer to...). Figure 10 After passing through the air inlet 40, the nitrogen gas blows the fan blade 43, causing it to rotate the rotating rod 42. As the rotating rod 42 and fan blade 43 rotate, the resulting centrifugal force causes the blocking member 49 to overcome the tension of the spring 48 and move outwards towards the spray pipe 46. When the spray pipe 46 moves directly above the bottom hole 41, the blocking member 49 no longer obstructs the bottom hole 41. At this point, the liquid isopropanol inside the rotating rod 42 is thrown out through the bottom hole 41 to mix with the nitrogen gas, and then blown vertically downwards towards the product. 8. If there are water droplets on the surface of product 8, the downward airflow is aligned with the gravitational flow of the water droplets, which can promote the water to flow down the workpiece surface more quickly, accelerating the drying process. Furthermore, after nitrogen and isopropanol are mixed, the isopropanol molecules will disperse in the nitrogen, increasing the contact area with air. Isopropanol has high volatility; when acting together with nitrogen, its rapid evaporation will carry away a large amount of heat, creating a localized low-temperature environment. The lower temperature will reduce the saturated vapor pressure of water, making it more likely to change from liquid to gas, further increasing its evaporation rate and promoting faster evaporation of surrounding moisture, thus accelerating the overall drying speed. This improves the efficiency of the subsequent horizontal blowing of the air knife 22 onto the surface of product 8. If there are many water stains on the surface of product 8, the blowing power of the air knife 22 can be increased. When the blowing power of the air knife 22 is increased, under the influence of a larger nitrogen airflow, the fan blade 43 will drive the rotating rod 42 to rotate rapidly. When the rotating rod 42 rotates rapidly, under the action of a large centrifugal force, the blocking component 49 will overcome the pulling force. The tension of spring 48 moves a greater distance outside the top hole 47 until it contacts the limiting member 1. When the blocking member 49 contacts the limiting member 1, the blocking member 49 no longer blocks the bottom hole 41 and the top hole 47. At this time, the liquid isopropanol stored in the rotating rod 42 will be thrown to the outside through the bottom hole 41 and the top hole 47 to mix with nitrogen. The amount of isopropanol thrown by the spray pipe 46 will increase compared to before. After it mixes with more nitrogen, the drying efficiency can be further improved, thereby meeting the drying requirements of products 8 with more water stains.

[0038] It should be noted that when the rotating rod 42 rotates, it will drive the through hole 45 at its end to rotate synchronously. When the through hole 45 rotates to coincide with the opening end of the liquid inlet pipe 2, the isopropanol stored in the liquid storage tank 38 will enter the rotating rod 42 through the liquid inlet pipe 2 and through the through hole 45.

[0039] It should be noted that the air inlet box 3 and the air outlet 40 are not tightly attached to the surface of the hanging frame 5, but there is a gap between them. When it is necessary to install the product 8, the product 8 can be inserted into the hanging frame 5 through the gap, and then the product 8 can be clamped by multiple clamps 7.
