Abstract
Description
Technical Field
[0001] This utility model relates to the field of sedimentation tank technology production, specifically an anti-sticking dryer feeding device. Background Technology
[0002] In many industrial production processes, material drying is one of the key steps, especially for powder or granular materials that are easily hygroscopic, easily softened, or contain organic components. This equipment dries wet materials in industries such as chemical, pharmaceutical, food, and metallurgy through its internal structure and hot air flow.
[0003] Traditional drying equipment often experiences material sticking to the walls and clogging during use due to factors such as the humidity, viscosity, or static electricity of the material. To address the material sticking problem in dryers, existing technologies generally employ a spiral feeding mechanism, which continuously pushes the material through spiral blades to avoid local accumulation, or a vibrator is installed at the feed inlet to promote material flow, thus alleviating the sticking phenomenon to some extent.
[0004] However, when the conveyed material has small volume, high moisture content, or is prone to agglomeration, it tends to clump together into larger clumps, resulting in uneven drying and reduced production capacity. Furthermore, it tends to adhere to the spiral blades and shaft during the conveying process, and long-term accumulation can lead to blockages or scaling, affecting conveying efficiency and requiring disassembly and maintenance. However, traditional spiral feeding mechanisms have fixed structures, are difficult to clean, and have high maintenance costs. Utility Model Content

[0012] Preferably, a bidirectional spring rod is fixedly connected to the bottom of the crushing trough, and arc-shaped locking blocks are fixedly connected to both ends of the bidirectional spring rod. A fixing groove is provided on one side of the main body of the mounting frame. When the sealing cover is rotated to fit against the top of the crushing trough, the arc-shaped locking blocks are engaged inside the fixing groove.
[0013] Compared with the prior art, the beneficial effects of this utility model are: The anti-sticking dryer feeding device proposed in this utility model uses a spiral conveyor to transport the material fed into the feeding trough to the crushing trough. Smaller materials pass directly through the screen holes and enter the drying oven through the discharge hopper. However, materials that agglomerate and stick together will remain inside the crushing trough. At this time, the rotating shaft drives the connecting shaft to rotate, causing the crushing blades to rotate within the sealing cover and the crushing trough. This stirs and crushes the material entering the sealing cover and the crushing trough until it can pass through the screen holes, reducing the amount of agglomerated and sticky material entering the drying oven and avoiding uneven drying that affects production capacity. After long-term use, the operator can rotate the sealing cover from the top of the crushing trough to open it. At the same time, the sealing cover drives the inspection cover to detach from the top of the cleaning trough, allowing the connecting shaft and crushing blades, as well as the rotating shaft and spiral conveyor, to be cleaned. The structure is simple and easy to maintain.

[0015] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0016] Example 1 Please see Figures 1-4 This utility model provides a technical solution: a feeding device for an anti-sticking dryer, comprising: a fixed frame 1, the fixed frame 1 including a mounting frame body 11, a spiral feeding mechanism 2 fixedly connected to one side of the top of the mounting frame body 11, and a crushing mechanism 3 fixedly connected to the other side of the top of the mounting frame body 11, the crushing mechanism 3 including a connecting shaft 31, one end of the connecting shaft 31 being rotatably connected to the fixed frame 1, and crushing blades 32 fixedly connected to the outer wall of the connecting shaft 31; a crushing groove 34 fixedly connected to the top of the mounting frame body 11, the inner wall of the crushing groove 34 being in contact with the crushing blades 32, and a plurality of sieve holes 35 being opened at the bottom of the crushing groove 34. The bottom of the crushing trough 34 is fixedly connected to a discharge hopper 36, and the top of the crushing trough 34 is rotatably connected to a sealing cover 33. The bottom of the mounting frame body 11 is fixedly connected to a motor 12, and the output end of the motor 12 is fixedly connected to a transmission wheel 13. A transmission belt is sleeved on the outer wall of the transmission wheel 13, and a transmission wheel 14 is sleeved on the top of the transmission belt. The spiral feeding mechanism 2 includes a rotating shaft 21, one end of which is rotatably connected to the mounting frame body 11, the outer wall of which is fixedly connected to the transmission wheel 14, and a spiral conveying blade 22 is fixedly connected to the outer wall of which. The end of the rotating shaft 21 that passes through the sealing cover 33 and the crushing trough 34 is fixedly connected to a connecting shaft 31.
[0017] It should be noted that in actual use, the operator starts the motor 12, which drives the first transmission wheel 13 to rotate. The first transmission wheel 13 drives the second transmission wheel 14 to rotate via a transmission belt. The second transmission wheel 14 drives the rotating shaft 21 to rotate, which in turn drives the spiral conveyor blades 22 to rotate. The material to be dried is fed into the feeding hopper 23 and enters the feeding trough 24. The spiral conveyor blades 22 then convey the material in the feeding trough 24 to the sealing cover 33 and the crushing trough 34. During the conveying process, material agglomeration and sticking can easily occur. In summary, when the material enters the crushing trough 34, smaller materials pass directly through the screen holes 35 and enter the drying oven through the discharge hopper 36. However, materials that agglomerate and stick together will remain inside the crushing trough 34. At this time, the connecting shaft 31 is driven to rotate by the rotating shaft 21. The connecting shaft 31 drives the crushing blades 32 to rotate within the sealing cover 33 and the crushing trough 34, stirring and crushing the materials entering the sealing cover 33 and the crushing trough 34 until they can pass through the screen holes 35. This reduces the amount of agglomerated and sticky materials entering the drying oven and avoids uneven drying that affects production capacity.
[0018] A feeding hopper 23 is fixedly connected to the top of the mounting frame body 11, and a feeding trough 24 is fixedly connected to the bottom of the feeding hopper 23. The inner wall of the feeding trough 24 is in contact with the spiral conveyor blade 22. A cleaning groove 26 is opened at the top of one end of the feeding trough 24. An inspection cover 37 is fixedly connected to one side of the crushing trough 34. When the sealing cover 33 is rotated to be in contact with the top of the crushing trough 34, the inspection cover 37 is inserted into the cleaning groove 26. A bidirectional spring rod 38 is fixedly connected to the bottom of the crushing trough 34. Arc-shaped locking blocks 39 are fixedly connected to both ends of the bidirectional spring rod 38. A fixing groove 15 is opened on one side of the mounting frame body 11. When the sealing cover 33 is rotated to be in contact with the top of the crushing trough 34, the arc-shaped locking blocks 39 are locked inside the fixing groove 15.
[0019] It should be noted that after long-term use, materials may easily adhere to the spiral conveyor blades 22 and crushing blades 32, causing blockages or scaling. At this time, the operator can press the arc-shaped locking block 39 to retract the bidirectional spring rod 38, which can rotate the sealing cover 33 from the top of the crushing trough 34 to open it. At this time, the connecting shaft 31 and the crushing blades 32 inside the crushing trough 34 can be cleaned. Simultaneously, the sealing cover 33 drives the inspection cover 37 to detach from the top of the cleaning trough 26, allowing the rotating shaft 21 and the spiral conveyor blades 22 inside the feeding trough 24 to be cleaned. After cleaning, the operator can rotate the crushing trough 34 to close it, allowing the bidirectional spring rod 38 to be inserted into the fixing groove 15. The arc-shaped locking block 39 will then reset and lock inside the fixing groove 15, achieving quick cleaning and maintenance.
[0020] In actual use, the operator starts the motor 12, which drives the transmission wheel 13 to rotate. The transmission wheel 13 drives the transmission wheel 24 to rotate via the transmission belt. The transmission wheel 24 drives the rotating shaft 21 to rotate, which in turn drives the spiral conveyor blades 22 to rotate. The material to be dried is fed from the feeding hopper 23 into the feeding trough 24. The spiral conveyor blades 22 then convey the material in the feeding trough 24 to the sealing cover 33 and the crushing trough 34. During conveying, material agglomeration and adhesion can easily occur. When the material enters the crushing trough 34, smaller pieces of material pass directly through the screen holes 35 and into the drying oven through the discharge hopper 36. However, agglomerated and adhered material will remain inside the crushing trough 34. At this time, the rotating shaft 21 drives the connecting shaft 31 to rotate, which in turn drives the crushing blades 32 to rotate within the sealing cover 33 and the crushing trough 34, thus conveying the material into the sealing cover 33 and the crushing trough 34. The material in the crushing trough 34 is agitated and crushed until it can pass through the screen holes 35, reducing the amount of agglomerated material entering the drying oven and avoiding uneven drying that affects production capacity. After long-term use, the material is prone to adhering to the spiral conveyor blades 22 and crushing blades 32, causing blockage or scaling. At this time, the operator can press the arc-shaped locking block 39 to retract the bidirectional spring rod 38, which can rotate the sealing cover 33 from the top of the crushing trough 34 to open it. At this time, the connecting shaft 31 between the sealing cover 33 and the inside of the crushing trough 34 and the crushing blades 32 can be cleaned. At the same time, the sealing cover 33 drives the inspection cover 37 to disengage from the top of the cleaning trough 26, so that the rotating shaft 21 and the spiral conveyor blades 22 inside the feeding trough 24 can be cleaned. After cleaning, the operator can rotate the crushing trough 34 to close it, so that the bidirectional spring rod 38 is inserted into the fixing groove 15, and the arc-shaped locking block 39 is reset and locked inside the fixing groove 15, realizing quick cleaning and maintenance.
