Description

Technical Field

[0001] This utility model relates to the field of mixed wet drying technology, specifically a mixed wet drying device. Background Technology

[0002] A mixing unit is a unit that uses mechanical force and gravity to uniformly mix two or more materials. It can increase the contact surface area of ​​the materials, promote chemical reactions and physical changes. However, some mixed materials have a high moisture content and need to be dried by the drying device in the mixing unit.

[0003] Patent document CN218296577U discloses a drying device for a mixer, relating to the technical field of mixers. The device includes a base, a feeding box, and a drying chamber. A first drying component is located on one side of the drying chamber, and a second drying component is located inside the feeding box. The first drying component includes an oven and an exhaust pump. A connecting pipe is fixedly connected to one side of the drying chamber, and the oven is installed at the upper end of the connecting pipe. A control board is located at the rear of the oven, and the exhaust pump is installed on the upper side of the oven. Placement slots are formed on the inner walls of the feeding box, and a placement box is detachably placed within these slots. Several ventilation holes are formed on the placement box, and a desiccant is placed inside. The oven and exhaust pump increase the air temperature inside the drying chamber, thus evaporating the moisture in the material in the first step, thereby drying it. After drying, the material enters the feeding box, where the desiccant absorbs any remaining moisture, resulting in better drying and less moisture content.

[0004] Although the aforementioned application documents state that using an oven and exhaust pump can increase the air temperature inside the drying chamber to evaporate the moisture in the material in the first step, thus achieving better drying and less moisture, the hot air mainly transfers heat to the material surface through convection during drying. If the material is statically piled up, only the surface layer can fully contact the hot air, while the inner material is trapped, making it difficult for heat to penetrate and for internal moisture to escape. This leads to uneven drying, where the outer layer may be over-dried or even charred, while the inside remains wet.

[0005] Therefore, a hybrid wet drying device is proposed to solve the problems mentioned above. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a hybrid wet drying device that solves the problem that during drying, hot air mainly transfers heat to the material surface through convection. If the material is statically piled up, only the surface material can fully contact the hot air, while the inner material is trapped, making it difficult for heat to enter and for internal moisture to be discharged. This leads to uneven drying, where the outer layer may be over-dried or even charred while the inside remains wet.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a drying tank, wherein a shaking mechanism is installed inside the drying tank, and a protective cover is fixedly connected to the top of the drying tank; The shaking mechanism includes a first rotating rod, which is rotatably connected to the lower surface of the drying tank via a bearing. A movable rod is fixedly connected to the lower surface of the first rotating rod, and a slider is hinged to the lower surface of the movable rod via a hinge rod. A vertical rod is fixedly connected to the upper surface of the inner wall of the drying tank, and a second rotating rod is rotatably connected to the side of the vertical rod via a bearing. A rotating slide rail is fixedly sleeved on the outer wall of the arc-shaped surface of the second rotating rod, and a movable groove is opened inside the rotating slide rail. A first rocker arm is fixedly connected to the lower surface of the rotating slide rail, and a second rocker arm is fixedly connected to the outer wall of the arc-shaped surface of the first rocker arm.

[0008] Preferably, a sealing sleeve is fixedly connected to the upper surface of the drying tank, and the sealing sleeve is disposed on the outer wall of the arc-shaped surface of the first rotating rod.

[0009] Preferably, a motor is fixedly connected to the upper surface of the inner wall of the protective cover, the first rotating rod movably penetrates the drying tank, the extension end of the first rotating rod extends toward the upper surface of the drying tank, and the extension end of the first rotating rod is fixedly connected to the output end of the motor.

[0010] Preferably, the moving rod is L-shaped, the included angle of the moving rod is 160 degrees, and the slider is slidably connected to the inner wall of the moving groove.

[0011] Preferably, the drying tank is equipped with a scraping mechanism.

[0012] Preferably, the scraping mechanism includes a connecting rod, which is fixedly sleeved on the outer wall of the arc-shaped surface of the first rotating rod, and a magnetic conductor is fixedly connected to the lower surface of the connecting rod. A scraper is slidably connected to the inner wall of the arc-shaped surface of the drying tank.

[0013] Preferably, a permanent magnet is fixedly connected to the upper surface of the scraper, and the permanent magnet is magnetically connected to the magnetic conductor.

[0014] Preferably, a vacuum tube is fixedly connected to the side of the drying tank, a hot air duct is fixedly connected to the side of the drying tank, a feed pipe is fixedly connected to the side of the drying tank, and a discharge pipe is fixedly connected to the lower surface of the drying tank.

[0015] Compared with the prior art, this utility model provides a hybrid wet drying device, which has the following beneficial effects: 1. The periodic oscillation of the rotating slide rail drives the first and second rockers to move the material, causing the material to tumble irregularly inside the drying tank. This tumbling allows all the material surfaces to be fully exposed to the hot air, greatly increasing the contact area between the hot air and the material.

[0016] Second, during the drying process, the wet material adheres to the tank wall. Driven by the magnetic coupling between the permanent magnet and the magnetic conductor, the scraper slides close to the inner wall to scrape off the adhering layer in real time and automatically.

[0019] 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 protection scope of the present utility model.

[0020] Example 1

[0021] See Figures 1-5 This embodiment provides a hybrid wet drying device, including a drying tank 1, a shaking mechanism 2 installed inside the drying tank 1, and a protective cover 4 fixedly connected to the top of the drying tank 1; The shaking mechanism 2 includes a first rotating rod 21, which is rotatably connected to the lower surface of the drying tank 1 via a bearing. A movable rod 25 is fixedly connected to the lower surface of the first rotating rod 21. A slider 26 is hinged to the lower surface of the movable rod 25 via a hinge rod 27. A vertical rod 210 is fixedly connected to the upper surface of the inner wall of the drying tank 1. A second rotating rod 211 is rotatably connected to the side of the vertical rod 210 via a bearing. A rotating slide rail 28 is fixedly sleeved on the outer wall of the arc-shaped surface of the second rotating rod 211. A movable groove 29 is opened inside the rotating slide rail 28. A first rocker arm 212 is fixedly connected to the lower surface of the rotating slide rail 28. A second rocker arm 23 is fixedly connected to the outer wall of the arc-shaped surface of the first rocker arm 212.

[0022] A sealing sleeve 22 is fixedly connected to the upper surface of the drying tank 1. The sealing sleeve 22 is located on the outer wall of the arc-shaped surface of the first rotating rod 21.

[0023] A motor 24 is fixedly connected to the upper surface of the inner wall of the protective cover 4. The first rotating rod 21 moves through the drying tank 1. The extension end of the first rotating rod 21 extends to the upper surface of the drying tank 1. The extension end of the first rotating rod 21 is fixedly connected to the output end of the motor 24.

[0024] The moving rod 25 is L-shaped with an included angle of 160 degrees, and the slider 26 is slidably connected to the inner wall of the moving groove 29.

[0025] In practical use, the above-mentioned equipment is activated by starting the motor 24, which drives the first rotating rod 21 to rotate. The first rotating rod 21 drives the moving rod 25 to rotate, and the moving rod 25 drives the slider 26 to slide on the inner wall of the moving groove 29. When the moving rod 25 rotates to the front, the moving rod 25 and the slider 26 also slide to the middle of the moving groove 29. At the same time, the moving rod 25 and the slider 26 will press the rotating slide rail 28 to make the second rotating rod 211 rotate clockwise with the center. The rotating slide rail 28 will drive the first rocker arm 212 and the second rocker arm 23 at the bottom to move the material inside the drying tank 1. This process is repeated to improve the drying efficiency of the material.

[0026] Example 2

[0027] See Figures 2-3 Based on Example 1, the drying tank 1 is equipped with a scraping mechanism 3.

[0028] The scraping mechanism 3 includes a connecting rod 31, which is fixedly sleeved on the outer wall of the arc-shaped surface of the first rotating rod 21. A magnetic conductor 32 is fixedly connected to the lower surface of the connecting rod 31, and a scraper 34 is slidably connected to the inner wall of the arc-shaped surface of the drying tank 1.

[0029] A permanent magnet 33 is fixedly connected to the upper surface of the scraper 34, and the permanent magnet 33 is magnetically connected to the magnetic conductor 32.

[0030] A vacuum tube 5 is fixedly connected to the side of the drying tank 1, a hot air tube 8 is fixedly connected to the side of the drying tank 1, a feed pipe 6 is fixedly connected to the side of the drying tank 1, and a discharge pipe 7 is fixedly connected to the lower surface of the drying tank 1.

[0031] When the above equipment is used, the first rotating rod 21 rotates, which drives the connecting rod 31 to rotate. The connecting rod 31 drives the magnetic conductor 32 to rotate. The magnetic conductor 32 drives the permanent magnet 33 to rotate. The permanent magnet 33 drives the scraper 34 to scrape off the material adhering to the inner wall of the drying tank 1.

[0032] Workflow: Close the discharge pipe 7 valve, pump the high-humidity material into the drying tank 1 through the feed pipe 6, close the feed pipe 6 valve, ensure all interfaces are sealed, start the motor 24, drive the first rotating rod 21 to rotate, thereby causing the material inside the entire drying tank 1 to begin periodic shaking. The material is continuously dispersed in the drying tank 1. By connecting the hot air pipe 8 to the output flange of the external hot air blower, filtered dry hot air is introduced into the drying tank 1. At this time, the drying tank 1 is at normal pressure or slightly negative pressure, and the humid and hot exhaust gas is discharged from the exhaust port of the hot air pipe 8. While shaking and hot air is being introduced, the scraping mechanism 3 continues to work. The rotating magnetic conductor 32 drives the scraper 34 to slide tightly against the tank wall through magnetic force, preventing the wet material from sticking to the tank wall in the initial stage. When the moisture content of the material decreases and the drying rate slows down, close the hot air pipe 8 valve and open the vacuum pipe 5 valve to create a vacuum. Pipe 5 is connected to the external vacuum pump flange. The vacuum pump unit is started to remove the air and residual water vapor in the drying tank 1. The pressure in the drying tank 1 drops rapidly. Hot water or steam is introduced into the jacket of the drying tank 1 for conduction heating. Since the drying tank 1 is under vacuum, the boiling point of water is lowered, and the moisture inside the material begins to boil and escape at a lower temperature. Shaking causes the material to continuously renew the contact surface with the tank wall, obtaining uniform heat conduction. The scraper continuously cleans up the material that may stick to the wall again due to low-temperature concentration. Clean nitrogen or dry air is slowly injected into the drying tank 1 through the vacuum pipe 5 until the pressure in the drying tank 1 returns to normal pressure. The motor 24 is stopped, and the shaking mechanism 2 and the scraping mechanism 3 stop working. The valve at the bottom of the discharge pipe 7 is opened. Due to the previous shaking and scraping action, the material has become loose and does not stick to the wall. It can be smoothly discharged from the discharge pipe 7 under the action of gravity.

[0033] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. As long as they can achieve their beneficial effects, they can be implemented. Therefore, this embodiment will not elaborate on their specific structural composition and working principle.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
