Description

Technical Field

[0001] This utility model relates to the field of drying technology, and in particular to a dehumidifying fan for a drying kiln. Background Technology

[0002] Drying technology is a discipline that integrates knowledge from multiple disciplines and focuses on the dehydration, solidification, preservation, or performance optimization of materials by removing moisture or other volatile components. In the field of drying technology, the drying kiln is a key piece of equipment for material drying, and its internal humidity control directly affects drying efficiency and material quality.

[0003] Regarding existing related technologies, the inventors believe that the following defects often exist: Existing dehumidifying fans for drying kilns lack effective filtration and cleaning devices, allowing particulate matter in the moisture to easily adhere to the inner wall of the fan's air inlet duct. Over time, these deposits gradually accumulate, causing blockage of the air inlet duct and thus affecting the fan's dehumidification effect. In addition, the particulate matter mixes with the moisture and re-enters the air, causing secondary environmental pollution and affecting the stability of the environment surrounding the drying kiln. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the existing drying kiln dehumidifier lacks an effective filtration and cleaning device, which makes it easy for particulate matter to adhere to the inner wall of the air inlet pipe, causing blockage. Furthermore, the mixing of particulate matter with moisture can cause secondary environmental pollution. Therefore, we propose a drying kiln dehumidifier.

[0005] To achieve the above objectives, this application adopts the following technical solution: a dehumidifying fan for a drying kiln, comprising a main body: an air inlet pipe fixed to one side of the main body, a regeneration air supply pipe fixed to one side of the main body, the regeneration air supply pipe located on one side of the air inlet pipe, an installation pipe fixed to one end of the air inlet pipe, a fan body installed inside the installation pipe, a filter plate fixed inside the air inlet pipe, a fixing frame fixed inside the air inlet pipe, two telescopic rods fixed to the bottom of the fixing frame, a scraper fixed to the bottom end of the telescopic rods, one side of the scraper contacting one side of the filter plate, a groove opened inside the air inlet pipe, the groove located on one side of the filter plate, and a collector fixed to the bottom of the air inlet pipe. The collection box has fixed housings on both sides of the air inlet pipe, and connecting blocks on both ends of the collection box. A square block is located inside the fixed housing. A connecting rod is fixed to one side of the square block, and a circular plate is fixed to one end of the connecting rod. Connecting rods are rotatably connected to both ends of one side of the square block via a first rotating shaft. A vertical rod is rotatably connected to the other end of the connecting rod via a second rotating shaft. An insert block is fixed to one side of the vertical rod. Slots for engaging with the insert blocks are provided at both ends of the connecting block. A pull plate is slidably connected to the surface of the connecting rod, and fixed blocks are fixed to both ends of the pull plate. Four fixing grooves are provided on one side of the fixed housing for engaging with the fixing blocks.

[0006] Preferably, a first spring is slidably connected to the surface of the connecting rod, one end of the first spring is fixed to the circular plate, and the other end of the first spring is fixed to the pull plate.

[0007] Preferably, guide blocks are fixed at both ends of the square block, and guide grooves that cooperate with the guide blocks are provided inside the fixed shell.

[0008] Preferably, a through rod is fixed inside the fixed shell, and the surface of the through rod is slidably connected to the inside of the vertical rod.

[0009] Preferably, a second spring is fixed to one side of the vertical rod, the other end of the second spring is fixed to the fixed shell, and the second spring is slidably connected to the surface of the through rod.

[0010] Preferably, one end of the mounting tube is fixed with a dust cover.

[0011] Preferably, adjustable feet are provided at each of the four corners of the bottom of the main body, and casters are fixed at each of the four corners of the bottom of the main body, with the casters located on one side of the adjustable feet.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] In this invention, by placing the collection box at the bottom of the air inlet pipe, pulling the pull plate outward causes the fixing block to leave the inside of the fixing groove, pulling the connecting rod causes the square block to move, causing the rotating shaft and connecting rod to squeeze the vertical rod, pushing the insert block into the slot, thus completing the connection between the air inlet pipe and the collection box. The fan body extracts the moisture, and after the filter plate intercepts the particles, the scraper can periodically scrape off the particles attached to the filter plate, allowing them to enter the collection box through the groove, achieving the effect of dry and wet separation. Through the above, dust and particles in the moisture can be prevented from entering the inside of the fan body, significantly extending the service life of the fan body, reducing maintenance costs, and effectively preventing particles from mixing with moisture and re-entering the air, reducing environmental pollution and improving environmental stability.

Both ends of one side of the square block 13 are rotatably connected to connecting rods 16 through a first rotating shaft. The other end of the connecting rod 16 is rotatably connected to a vertical rod 17 through a second rotating shaft. An insert block 18 is fixed to one side of the vertical rod 17. The connecting block 1... Both ends of the duct 2 have slots 19 for use with the insert 18. A pull plate 20 is slidably connected to the surface of the connecting rod 14. Fixing blocks 21 are fixed at both ends of the pull plate 20. A fixing groove 22 for use with the fixing block 21 is opened on one side of the fixing shell 11. There are four fixing grooves 22. By placing the collection box 10 at the bottom of the air inlet pipe 2 and pulling the pull plate 20 outward, the fixing blocks 21 are moved away from the inside of the fixing grooves 22. The connecting rod 14 is pulled to move the square block 13, which causes the rotating shaft and connecting rod 16 to squeeze the vertical rod 17, pushing the insert 18 into the slot 19. The fan body 28 draws out moisture, and after the filter plate 5 intercepts particulate matter, the scraper 8 periodically scrapes off the particulate matter attached to the filter plate 5, allowing it to enter the collection box 10 through the groove 9, thus achieving the effect of dry and wet separation. Through the above, dust and particulate matter in the moisture can be prevented from entering the interior of the fan body 28, significantly extending the service life of the fan body 28, reducing maintenance costs, and effectively preventing particulate matter from mixing with moisture and re-entering the air, reducing environmental pollution and improving environmental stability.

One end of the first spring 23 is fixed to the circular plate 15, and the other end of the first spring 23 is fixed to the pull plate 20. By setting the structure of the first spring 23, when the pull plate 20 is pulled to move the fixed block 21, the first spring 23 will deform. After the pull plate 20 is released, the elastic restoring force of the first spring 23 can drive the fixed block 21 to automatically reset without manual reset.

[0024] Reference Figure 4 As shown in this embodiment: guide blocks 24 are fixed at both ends of the square block 13, and guide grooves 25 that cooperate with the guide blocks 24 are provided inside the fixed shell 11. By setting the structure of guide blocks 24 and guide grooves 25, the movement path of the square block 13 is effectively constrained, and the phenomenon of deviation is avoided.

[0025] Reference Figure 4 As shown in this embodiment: a through rod 26 is fixed inside the fixed shell 11. The surface of the through rod 26 is slidably connected to the inside of the vertical rod 17. By setting the structure of the through rod 26, the consistency and stability of the vertical rod 17 during movement are ensured, and it also plays a role in assisting movement.

The second spring 27 is slidably connected to the surface of the through rod 26. By setting the structure of the second spring 27, when the vertical rod 17 moves, the second spring 27 will be stretched or compressed. Its elastic restoring force can assist the vertical rod 17 to return to its original position, and at the same time play a buffering role in the movement of the vertical rod 17.

[0027] Reference Figure 5 As shown in this embodiment, a dust cover 29 is fixed to one end of the installation pipe 4. By setting the structure of the dust cover 29, external dust and debris can be effectively blocked from entering the interior of the installation pipe 4, preventing impurities from adhering to the surface of the fan body 28 and affecting its working efficiency. At the same time, it can also prevent impurities from entering the interior of the main body 1 and causing damage to the components, thus playing a good protective role and reducing the maintenance cost of the equipment.

[0028] Reference Figure 1As shown in this embodiment: Adjustable feet 30 are provided at each of the four corners of the bottom of the main body 1, and casters 31 are fixed at each of the four corners of the bottom of the main body 1. The casters 31 are located on one side of the adjustable feet 30. By setting the structure of the adjustable feet 30 and the casters 31, the adjustable feet 30 can be height adjusted according to the flatness of the ground, so that the main body 1 can be placed stably under different terrain conditions, avoiding the shaking or tilting of the main body 1 due to uneven ground, thereby ensuring the operational stability and safety of the main body 1. At the same time, the equipping of the casters 31 allows the main body 1 to be easily adjusted in position when it needs to be moved, which facilitates the handling and installation of the main body 1 and improves the flexibility and convenience of use.

The through rod 26 ensures the consistency and stability of the vertical rod 17's movement and also assists in its movement. The second spring 27, when the vertical rod 17 moves, is stretched or compressed; its elastic restoring force assists the vertical rod 17 in returning to its original position and also buffers its movement. The dust cover 29 effectively prevents external dust and debris from entering the installation pipe 4, avoiding impurities adhering to the surface of the fan body 28 and affecting its working efficiency. It can prevent impurities from entering the interior of the main body 1 and causing damage to the components, thus playing a good protective role and reducing the maintenance cost of the equipment. By setting the structure of the adjustable feet 30 and the casters 31, the adjustable feet 30 can adjust the height according to the flatness of the ground, so that the main body 1 can be placed stably under different terrain conditions, avoiding the shaking or tilting of the main body 1 due to uneven ground, thereby ensuring the operational stability and safety of the main body 1. At the same time, the 31 casters 31 make it easy to adjust the position of the main body 1 when it needs to be moved, which facilitates the handling and installation of the main body 1 and improves the flexibility and convenience of use.
