Description

Technical Field

[0001] This utility model belongs to the field of vacuum drying oven technology, specifically a vacuum drying oven with a flipping structure. Background Technology

[0002] Vacuum drying ovens are designed specifically for drying heat-sensitive, easily decomposed, and easily oxidized substances. During operation, they can maintain a certain degree of vacuum inside the chamber and can be filled with inert gas. They can also quickly dry some complex items. They use an intelligent digital temperature controller for temperature setting, display, and control.

[0003] In recent years, some improved vacuum drying ovens have emerged, such as vacuum drying ovens with a flipping structure. The flipping structure uses a drive mechanism to continuously flip the material during the drying process, thereby improving the drying uniformity. However, the fixed frame inside the existing flipping structure vacuum drying oven is fixedly connected to the drive shaft, making it impossible to remove the fixed frame for thorough cleaning. Consequently, when drying different metal compounds, the residual metal compounds inside the fixed frame can easily affect the subsequent use of the metal compounds, thus reducing the safety of the vacuum drying device. Therefore, to address the above problems, a vacuum drying oven with a flipping structure is proposed. Utility Model Content

[0004] To overcome the shortcomings of existing technologies and address the problems of existing equipment, this utility model proposes a vacuum drying oven with a flipping structure.

[0005] The technical solution adopted by this utility model to solve its technical problem is a vacuum drying oven with a flipping structure, comprising: a vacuum drying oven body, a drive motor installed on one side of the vacuum drying oven body, a first drive shaft installed at the output end of the drive motor, a drive belt connected to the surface of the first drive shaft, a second drive shaft connected to the inner surface of the drive belt, both the first and second drive shafts being rotatably connected inside the vacuum drying oven body, with one end extending into the interior of the vacuum drying oven body, and a positioning groove fixedly formed at one end of both the first and second drive shafts, with a rod movably connected inside the positioning groove. A hollow rod is fixedly connected to one side of the insertion rod. An adjustment groove is opened inside the hollow rod, and a positioning rod is installed inside the hollow rod. Limiting plates are symmetrically arranged on both sides of the positioning rod. The limiting plates are slidably connected inside the adjustment groove. Springs are fixedly connected to the surface of each limiting plate. When the drive motor is started, the first transmission shaft rotates, thereby driving the transmission belt to rotate, which in turn drives the second transmission shaft to rotate. The rotation speed and direction of the first and second transmission shafts are the same, which can ensure the stable transmission of the transmission belt. This can drive the fixed frame to rotate continuously and stably, thereby improving the drying uniformity of the metal compound inside the fixed frame.

[0006] Preferably, one end of the spring is fixedly connected to the inner wall of the adjusting groove, and a connecting rod is fixedly connected to one side of both the first and second drive shafts. A conical block is fixedly connected to one end of the connecting rod. When the positioning rod is released, the pressure on the spring disappears, and its own elastic force pushes the limiting plate toward the connecting rod, thereby fixing the movement range of the conical block again.

[0007] Preferably, the connecting rod and the conical block are movably connected inside the hollow rod. A fixing frame is installed at one end of the hollow rod, and a cover plate is hinged to one side of the fixing frame. The cover plate closes the front side of the fixing frame, thereby preventing the metal compound from falling out when the fixing frame rotates.

[0008] Preferably, the cover plate and the fixing frame are threadedly connected with a first bolt, and a rotating rod is threadedly connected to one side of the fixing frame, with one end of the rotating rod extending to the outside of the vacuum drying oven body. The rotating rod is movably connected to the inside of the vacuum drying oven body. The fixing frame and the cover plate can be fixed using the first bolt, thereby improving the fixing strength of the metal compound.

[0009] Preferably, a gas supply pipe is installed on the vacuum drying oven body, and an elastic sheet is fixedly connected inside the gas supply pipe. A baffle is fixedly connected to one end of the elastic sheet. After the inert gas is delivered, the impact force on the elastic sheet decreases, and its own elasticity pushes the baffle back to its original position, thereby sealing the gas supply pipe, preventing air from entering the vacuum drying oven body, and preventing the leakage of inert gas inside the vacuum drying oven body.

[0010] Preferably, the baffle is hinged to the inner wall of the gas transmission pipe, and an anti-slip pad is fixedly connected to the outer wall of one end of the gas transmission pipe. A reinforcing ring is fixedly connected to the outer side of the anti-slip pad, and a second bolt is threaded onto the reinforcing ring. One end of the second bolt presses against one side of the reinforcing ring, thereby reducing the size of the reinforcing ring and thus improving the tightness of the connection between the inert gas pipeline and the gas transmission pipe.

[0011] The advantages of this invention are as follows: by unscrewing the rotating rod and simultaneously pulling the positioning rod outward, the bottom of the positioning rod is positioned in the adjustment groove, thus eliminating the obstruction on the conical block. Then, the fixing frame is pulled to one side, allowing the hollow rod to be removed from the conical block. The fixing frame can then be disassembled for cleaning, which facilitates the subsequent drying of metal compounds, avoids the conflicting properties of metal compounds that could affect subsequent use, and thus improves the safety of the vacuum drying oven.

[0012] This invention inserts an inert gas pipe into an anti-slip pad and connects it to a reinforcing ring using a second bolt. This reduces the size of the reinforcing ring and improves the tightness of the connection between the inert gas pipe and the gas delivery pipe. After the inert gas delivery is completed, the impact force on the elastic sheet decreases, pushing the baffle back to its original position and sealing the gas delivery pipe. This prevents inert gas leakage from the vacuum drying oven body, ensuring that the vacuum drying oven body always maintains a high vacuum state, lowering the boiling point of the material, and thus improving the drying efficiency of the vacuum drying oven for metal compounds.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0021] Please see Figure 1-5 As shown, a vacuum drying oven with a flip-over structure includes: a vacuum drying oven body 1; a drive motor 2 is mounted on one side of the vacuum drying oven body 1; a first drive shaft 3 is mounted on the output end of the drive motor 2; a drive belt 4 is drivenly connected to the surface of the first drive shaft 3; a second drive shaft 5 is drivenly connected to the inner surface of the drive belt 4; both the first drive shaft 3 and the second drive shaft 5 are rotatably connected inside the vacuum drying oven body 1, and one end extends into the interior of the vacuum drying oven body 1; a positioning groove 6 is fixedly opened at one end of both the first drive shaft 3 and the second drive shaft 5; an insert rod 7 is movably connected inside the positioning groove 6; a hollow rod 8 is fixedly connected to one side of the insert rod 7; an adjustment groove 9 is opened inside the hollow rod 8; and a positioning rod 10 is installed inside the hollow rod 8. Limiting plates 11 are symmetrically arranged on both sides. The limiting plates 11 are slidably connected to the inside of the adjusting groove 9. Springs 12 are fixedly connected to the surface of the limiting plates 11. One end of the springs 12 is fixedly connected to the inner wall of the adjusting groove 9. Connecting rods 13 are fixedly connected to one side of the first drive shaft 3 and the second drive shaft 5. A conical block 14 is fixedly connected to one end of the connecting rod 13. The connecting rod 13 and the conical block 14 are movably connected to the inside of the hollow rod 8. A fixing frame 15 is installed at one end of the hollow rod 8. A cover plate is hinged to one side of the fixing frame 15. A first bolt 16 is threadedly connected to the cover plate and the fixing frame 15. A rotating rod 17 is threadedly connected to one side of the fixing frame 15. One end of the rotating rod 17 extends to the outside of the vacuum drying oven body 1. The rotating rod 17 is movably connected to the inside of the vacuum drying oven body 1.

[0022] Vacuum drying of metallic compounds requires the use of a vacuum dryer. Existing tilting vacuum drying ovens suffer from the inconvenience of disassembling the fixed frame 15, increasing maintenance time and reducing efficiency. Therefore, a tilting vacuum drying oven is proposed. In practical use, the drive motor 2 is started, rotating the first transmission shaft 3, which in turn drives the transmission belt 4, which in turn drives the second transmission shaft 5. The first and second transmission shafts 3 and 5 rotate at the same speed and in the same direction, ensuring stable transmission of the transmission belt 4. This, in turn, drives the fixed frame 15 through two sets of hollow rods 8. The fixed frame 15 and the rotating rod 17 are flipped, thereby causing the metal compound inside the fixed frame 15 to rotate synchronously, increasing the uniformity of heating of the metal compound. After drying, the first bolt 16 is unscrewed, and the cover plate can be opened to remove the metal compound inside the fixed frame 15. Before drying another metal compound, the inside of the fixed frame 15 needs to be cleaned. Because the fixed frame 15 is threadedly connected to the rotating rod 17 and slidably connected to the vacuum drying chamber 1, the rotating rod 17 is rotated and pulled out of the vacuum drying chamber 1, so that the rotating rod 17 is moved out of the vacuum drying chamber body 1 and the fixed frame 15, thereby releasing the fixation on one side of the fixed frame 15. Then the positioning rod is... Pulling the positioning rod 10 outwards causes the limiting plate 11 to move synchronously and compresses the spring 12, so that the bottom of the positioning rod 10 is located in the adjusting groove 9, and the obstruction of the conical block 14 disappears. Then, the fixing frame 15 is pulled to one side, causing the hollow rod 8 and the insert rod 7 to move synchronously, so that the hollow rod 8 is moved out of the connecting rod 13 and the conical block 14. The fixing frame 15 can then be removed from the vacuum drying oven body 1 for cleaning. When installing the fixing frame 15, pull the positioning rod 10 upwards to insert the insert rod 7 into the positioning groove 6, so that the connecting rod 13 and the conical block 14 enter the hollow rod 8, thereby fixing the position of the hollow rod 8. When the positioning rod 10 is released, the pressure on the spring 12 disappears, and its own elastic force pushes the limiting plate 11 toward the connecting rod 13, causing the tail end of the positioning rod 10 to enter the hollow rod 8 and come into contact with the surface of the connecting rod 13, and to be located on one side of the conical block 14, thus cooperating with the hollow rod 8 to fix the position of the conical block 14. Then, in cooperation with the insertion rod 7, the positioning groove 6 and the rotating rod 17, the hollow rod 8 and the cleaned fixing bracket 15 can be reinstalled inside the vacuum drying oven body 1, which facilitates the subsequent drying of metal compounds, avoids the conflict of metal compound properties, avoids affecting subsequent use, and avoids reducing the safety of vacuum drying oven use.

[0023] Please see Figure 1-5As shown, a gas supply pipe 18 is installed on the main body 1 of the vacuum drying oven. An elastic sheet 19 is fixedly connected inside the gas supply pipe 18. A baffle 20 is fixedly connected to one end of the elastic sheet 19. The baffle 20 is hinged to the inner wall of the gas supply pipe 18. An anti-slip pad 21 is fixedly connected to the outer wall of one end of the gas supply pipe 18. A reinforcing ring 22 is fixedly connected to the outer side of the anti-slip pad 21. A second bolt 23 is threaded onto the reinforcing ring 22.

[0024] When vacuum drying metallic compounds, inert gas needs to be added to the vacuum drying oven body 1. The inert gas pipe is inserted into the anti-slip pad 21, with one end touching one end of the gas delivery pipe 18. Then, the second bolt 23 is screwed into the reinforcing ring 22, and one end of the second bolt 23 is pressed against one side of the reinforcing ring 22, which reduces the size of the reinforcing ring 22, thus cooperating with the anti-slip pad 21. This improves the tightness of the connection between the inert gas pipe and the gas delivery pipe 18, and reduces the impact generated when the inert gas enters the gas delivery pipe 18. The impact force pushes open multiple sets of baffles 20 and compresses the elastic sheet 19. After the inert gas delivery is completed, the impact force on the elastic sheet 19 decreases, and its own elasticity pushes the baffles 20 back to their original position, thereby sealing the gas delivery pipe 18, preventing air from entering the vacuum drying chamber body 1, and preventing the leakage of inert gas in the vacuum drying chamber body 1. This ensures that the vacuum drying chamber body 1 always maintains a high vacuum state, reduces the boiling point of the material, and improves the drying efficiency of the vacuum drying chamber for metal compounds.

[0025] Working principle: Starting the drive motor 2 rotates the first transmission shaft 3, which in turn drives the transmission belt 4, which in turn drives the second transmission shaft 5. Through two sets of hollow rods 8, this causes the fixed frame 15 and the rotating rod 17 to rotate, thus causing the metal compound inside the fixed frame 15 to rotate synchronously, increasing the uniformity of heating of the metal compound. After drying, the rotating rod 17 is unscrewed, and then the positioning rod 10 is pulled outwards from the hollow rod 8, so that the bottom of the positioning rod 10 is positioned within the adjusting groove 9, eliminating the obstruction to the conical block 14. Then, the fixed frame 15 is moved... Pulling the lateral side causes the hollow rod 8 and the insert rod 7 to move synchronously, allowing the hollow rod 8 to move out from the outside of the connecting rod 13 and the conical block 14. This allows the fixing frame 15 to be removed from the vacuum drying oven body 1 for cleaning. When installing the fixing frame 15, pull the positioning rod 10 upward to insert the insert rod 7 into the positioning groove 6. At the same time, the connecting rod 13 and the conical block 14 enter the hollow rod 8, thus fixing the position of the hollow rod 8. Releasing the positioning rod 10 releases the pressure on the spring 12, and its own elasticity pushes the limiting plate 11 toward the connecting rod 13, thereby moving the positioning rod. The tail end of 10 enters the hollow rod 8, adhering to the surface of the connecting rod 13 and located on one side of the conical block 14, thus cooperating with the hollow rod 8. This allows the hollow rod 8 and the cleaned mounting bracket 15 to be reinstalled inside the vacuum drying oven body 1 for subsequent drying of the metal compound. During the drying process, the inert gas pipe is inserted into the anti-slip pad 21, and then the second bolt 23 is screwed into the reinforcing ring 22, reducing the loop size of the reinforcing ring 22 to cooperate with the anti-slip pad 21, improving the tightness of the connection to the inert gas pipe. The impact force generated when the gas enters the gas delivery pipe 18 pushes open multiple sets of baffles 20 and squeezes the elastic sheet 19. After the inert gas delivery is completed, the impact force on the elastic sheet 19 decreases, and its own elasticity pushes the baffle 20 back to its original position, thereby sealing the gas delivery pipe 18, preventing air from entering the vacuum drying chamber body 1, and preventing the leakage of inert gas in the vacuum drying chamber body 1. This ensures that the vacuum drying chamber body 1 always maintains a high vacuum state, reduces the boiling point of the material, and improves the drying efficiency of the vacuum drying chamber for metal compounds.
