Description

Technical Field

[0001] This utility model relates to the field of material leveling technology for belt dryers, specifically a material leveling device for belt dryers. Background Technology

[0002] A belt dryer is a continuous drying equipment. Its working principle is to achieve the drying effect by passing hot air through the material layer. It is particularly suitable for drying sheet-like, strip-like, granular, and some paste-like materials.

[0003] Existing belt dryers mainly consist of a conveyor belt and a drying mechanism. When drying materials, the materials are first placed on the conveyor belt. The motor drives the conveyor belt to rotate, thus transporting the materials. The fan, in conjunction with the heating tubes, blows the heated high-temperature gas onto the surface of the materials, thereby enabling continuous drying.

[0004] Existing belt dryers lack a leveling mechanism, which makes it easy for materials to accumulate on the conveyor belt, resulting in uneven heating and drying and affecting the drying effect. Therefore, a material leveling device for belt dryers is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology and solve the problems mentioned in the background, this utility model proposes a material leveling device for a belt dryer.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A material leveling device for a belt dryer, comprising two support plates, with a housing fixedly connected to the top side of the two support plates. A pneumatic cylinder is installed on the top side of the housing, and a pneumatic rod is fitted to the working end of the pneumatic cylinder. A connecting frame is fixedly connected to the bottom end of the pneumatic rod, and a curved channel is fixedly connected to the connecting frame. A guide port is opened at one end of the curved channel, and a rotating rod is rotatably installed inside the guide port. Multiple cleaning brushes are fixed to the outer surface of the rotating rod. A motor is installed on one side wall of the curved channel, and the output end of the motor is connected to one end of the rotating rod. A protective cover is fixedly connected to the end of the guide port. A shovel plate is fixedly connected to one end of the curved channel, and a discharge port is opened at the other end of the curved channel. During the drying process, to prevent material accumulation on the conveyor belt, a leveling mechanism is set up. The material first falls onto the conveyor belt through the feed hopper. Next, the pneumatic cylinder is activated, causing the curved channel to move down to the desired thickness. The pneumatic cylinder then stops operating, and the motor is started, causing the conveyor belt to automatically transport the material. When the material reaches the bottom of the curved channel, due to the height limit set by the curved channel, excess material exceeding the set thickness is scooped up by the shovel and enters the curved channel. Simultaneously, the motor operates, causing the rotating rod to drive the cleaning brush to rotate. The high-speed rotation of the cleaning brush thoroughly sweeps the material from the shovel into the curved channel, preventing material residue on the shovel. For areas with depressions on the conveyor belt, when the material reaches the bottom of the curved channel, the material inside the curved channel is discharged through the outlet. This discharged material automatically fills the depressions, gradually flattening the material surface and completing the material leveling process. This ensures the material maintains a uniform thickness on the conveyor belt, facilitating even heating and drying of the subsequent material, thus improving the drying effect.

[0007] Preferably, two limiting grooves are provided on both sides of the box body, and a limiting block is provided in each limiting groove. The limiting block is fixed to the side wall of the curved channel. During the downward movement of the curved channel, the limiting groove and the limiting block cooperate to make the curved channel move downward stably.

[0008] Preferably, the top side of the box has two mounting holes, each with a fan installed inside. Two mounting plates are fixed between the inner walls of the two sides of the box, and multiple heating tubes are installed between the two mounting plates. When the material is flattened and dried, the fan operates, and with the cooperation of the heating tubes, the heated high-temperature gas is blown onto the surface of the material, thereby drying the material.

[0009] Preferably, both ends of the box are provided with openings, a feed hopper is fixed to one end of the opening, and an inclined guide plate is fixed to the other end of the opening. When using the device, the feed hopper facilitates the feeding of the material to be dried onto the conveyor belt for subsequent drying, and the inclined guide plate facilitates the discharge of the dried material.

[0010] Preferably, two rotating wheels are installed between the two support plates via a rotating shaft. An electric motor is installed on one support plate, and the output end of the electric motor is connected to one end of the rotating shaft. A conveyor belt is fitted onto the outer surface of the two rotating wheels. When automatically conveying materials, the electric motor operates, and the conveyor belt automatically conveys the materials.

[0011] Preferably, a support plate is fixed between the two support plates, and the support plate is disposed inside the conveyor belt. When using the device, by setting the support plate, the conveyor belt can be provided with stable support, preventing the conveyor belt from sinking and shifting due to the weight of the material, so that the conveyor belt can maintain stable operation when bearing heavy objects.

[0012] The advantages of this utility model are:

[0013] In this invention, to prevent material accumulation on the conveyor belt during the drying process, a leveling mechanism is installed. The material first falls onto the conveyor belt through the feed hopper. Then, a pneumatic cylinder is activated, causing the curved channel to descend to the desired leveling thickness. The pneumatic cylinder then stops operating, and the motor is started, allowing the conveyor belt to automatically transport the material. When the material reaches the bottom of the curved channel, due to the height limitation set by the curved channel, excess material exceeding the set thickness is scooped up by a shovel and enters the curved channel. Simultaneously, the motor rotates a cleaning brush, thoroughly sweeping the material from the shovel into the curved channel, preventing material residue on the shovel. For areas with depressions on the conveyor belt, when the material reaches the bottom of the curved channel, the material inside the channel is discharged through the outlet. This discharged material automatically fills the depressions, gradually leveling the material surface and completing the leveling process. This ensures the material maintains a uniform thickness on the conveyor belt, facilitating even heating and drying of the material subsequently, thus improving the drying effect.

[0021] 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.

[0022] Please see Figure 1-5As shown, a material leveling device for a belt dryer includes two support plates 1. A housing 2 is fixedly connected to the top side of the two support plates 1. A pneumatic cylinder 3 is installed on the top side of the housing 2. A pneumatic rod 4 is mounted on the actuating end of the pneumatic cylinder 3. A connecting frame 5 is fixedly connected to the bottom end of the pneumatic rod 4. A curved channel 6 is fixedly connected to the connecting frame 5. A guide port 7 is opened at one end of the curved channel 6. A rotating rod 9 is rotatably installed inside the guide port 7. Multiple cleaning brushes 10 are fixed to the outer surface of the rotating rod 9. A motor 8 is installed on one side wall of the curved channel 6. The output end of the motor 8 is connected to one end of the rotating rod 9. The guide port 7... A protective cover 13 is fixedly connected to the port. A shovel plate 11 is fixedly connected to one end of the curved channel 6, and a discharge port 12 is opened at the other end of the curved channel 6. Two limiting grooves 14 are opened on both sides of the box body 2. Each limiting groove 14 is equipped with a limiting block 15, and the limiting block 15 is fixedly connected to the side wall of the curved channel 6. During operation, in order to prevent the material from accumulating on the conveyor belt 25 when drying the material, a leveling mechanism is set up. The material first falls onto the conveyor belt 25 through the feed hopper 21. Then, the pneumatic cylinder 3 is activated to move the pneumatic rod 4 downward, thereby moving the connecting frame 5 and The curved channel 6 also moves downwards until it reaches the required flattening thickness. At this point, the pneumatic cylinder 3 stops operating, and the curved channel 6 stabilizes at the set height, preparing for subsequent flattening work. Then, the motor 24 is started, causing the rotating wheel 23 to drive the conveyor belt 25 to rotate, thereby enabling automatic material conveying. When the material is conveyed to below the curved channel 6, due to the height limit set by the curved channel 6, excess material exceeding the set thickness will be scooped up by the shovel plate 11 and enter the curved channel 6. Simultaneously, the motor 8 operates, causing the rotating rod 9 to drive the cleaning brush 10 to move. The high-speed rotation of the cleaning brush 10 thoroughly sweeps the material on the shovel plate 11 into the curved channel 6, preventing material residue on the shovel plate 11. For material areas with depressions on the conveyor belt 25, when the material is conveyed to the bottom of the curved channel 6, the material inside the curved channel 6 will be discharged through the discharge port 12. This discharged material will automatically fill the depressions, making the material surface gradually flattened. This completes the leveling operation of the material, ensuring that the material maintains a uniform thickness on the conveyor belt 25, which facilitates uniform heating and drying of the subsequent material, thereby improving the drying effect.

[0023] Please see Figure 2 As shown, two mounting holes 16 are opened on the top side of the box 2, and a fan 17 is installed in each of the two mounting holes 16. Two mounting plates 18 are fixed between the inner walls of the two sides of the box 2, and multiple heating tubes 19 are arranged between the two mounting plates 18. During operation, after the material is flattened, when it is dried, the fan 17 operates, and with the cooperation of the heating tubes 19, the heated high-temperature gas is blown onto the surface of the material, thereby drying the material.

[0024] Both ends of the housing 2 are provided with openings 20. A feed hopper 21 is fixedly connected to the port of one opening 20, and an inclined guide plate 22 is fixedly connected to the port of the other opening 20. When using this device, by setting the feed hopper 21, it is convenient to put the material to be dried onto the conveyor belt 25 for subsequent drying. By setting the inclined guide plate 22, it is convenient to discharge the material after drying.

[0025] Please see Figure 2 As shown, two rotating wheels 23 are installed between two support plates 1 via a rotating shaft. A motor 24 is installed on one support plate 1, and the output end of the motor 24 is connected to one end of the rotating shaft. A conveyor belt 25 is fitted onto the outer surface of the two rotating wheels 23. During operation, when automatically conveying materials, the motor 24 operates to drive the rotating wheels 23 to rotate the conveyor belt 25, thereby enabling automatic material conveying.

[0026] A support plate 26 is fixed between the two support plates 1, and the support plate 26 is set inside the conveyor belt 25. When using the device, by setting the support plate 26, the conveyor belt 25 can be provided with stable support, and the conveyor belt 25 can be prevented from sinking and moving down due to the weight of the material, so that the conveyor belt 25 can maintain stable operation when bearing heavy objects.

[0027] Working Principle: Existing belt dryers lack a leveling mechanism, causing material to easily accumulate on the conveyor belt 25, resulting in uneven drying and affecting the drying effect. Therefore, a material leveling device for a belt dryer is proposed to address this problem. During the drying process, to prevent material accumulation on the conveyor belt 25, a leveling mechanism is installed. The material first falls onto the conveyor belt 25 through the feed hopper 21. Then, the pneumatic cylinder 3 is activated, causing the pneumatic rod 4 to move downwards, which in turn moves the connecting frame 5 and the curved channel 6 downwards. When the curved channel 6 reaches the desired leveling thickness, the pneumatic cylinder 3 stops operating, and the curved channel 6 stabilizes at the set height, preparing for subsequent leveling. Then, the motor 24 is activated, causing the rotating wheel 23 to drive the conveyor belt 25 to rotate, thus automatically conveying the material. When the material is conveyed to the area below the curved channel 6, due to the height limitation set by the curved channel 6, excess material exceeding the set thickness will be scooped up by the shovel plate 11 and enter the curved channel 6. At the same time, the motor 8 operates, causing the rotating rod 9 to drive the cleaning brush 10 to rotate. Through the high-speed rotation of the cleaning brush 10, the material on the shovel plate 11 can be thoroughly swept into the interior of the curved channel 6, preventing material residue on the shovel plate 11. For material areas with depressions on the conveyor belt 25, when the material is conveyed to the area below the curved channel 6, the material inside the curved channel 6 will be discharged through the discharge port 12. This discharged material will automatically fill the depressions, making the material surface gradually flatten. This completes the leveling operation of the material, ensuring that the material maintains a uniform thickness on the conveyor belt 25, which facilitates uniform heating and drying of the material in the subsequent process, thereby improving the drying effect.
