Description

Technical Field

[0001] This utility model belongs to the field of fuel preparation technology, specifically a multi-raw material mixing type dense molding fuel preparation device. Background Technology

[0002] Densely molded fuel is a solid fuel made by physically compressing a mixture of various biomass raw materials or industrial waste. Its preparation process includes raw material crushing, drying, mixing and proportioning, high-temperature and high-pressure molding and cooling and shaping, ultimately forming granular, block or rod-shaped fuel.

[0003] In the raw material drying process, uneven heating of raw materials is a common problem. Most devices rely on a single heating element, such as tank wall heating. Raw materials tend to adhere to the tank wall, causing waste and risks. Long-term adhesion can easily form stubborn clumps, which are difficult to clean later. At the same time, clumps of raw materials can affect heat conduction inside the tank, further reducing the overall drying efficiency. Utility Model Content

[0013] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0014] like Figure 1-4 As shown, this utility model provides a technical solution: a multi-raw material mixing type dense molding fuel preparation device, including a drying tank 1, a support frame 2 connected to the bottom of the drying tank 1, a filling hopper 3 connected to the top of the drying tank 1, a connecting cover 4 connected to one side of the drying tank 1, multiple discharge ports 5 opened at the bottom of the drying tank 1, a sealing plate 6 slidably connected inside the drying tank 1, the sealing plate 6 is in contact with the inner wall of the drying tank 1, and a pull rod 22 is connected to one side of the sealing plate 6 through the drying tank 1. The sealing plate 6 is pushed and pulled by the pull rod 22 to close or expose the discharge ports 5, thereby realizing closed drying and material discharge. The installation is simple and easy to operate.

[0015] A fixed cylinder 7 is connected to one side of the inside of the drying tank 1. The fixed cylinder 7 has a groove 20 on the side facing the connecting cover 4. The groove 20 is designed in a conical shape. Through the guiding effect of the conical groove 20, the hot air flow can be effectively gathered and guided, thereby improving the drying effect.

[0016] A drive motor 8 is fixedly installed on one side of the drying tank 1. The output shaft of the drive motor 8 is connected to a rotating rod 9. Multiple stirring plates 10 are connected to the rotating rod 9. The rotating rod 9 is rotatably connected to the drying tank 1 and the fixed cylinder 7 through bearings. The multiple stirring plates 10 on the rotating rod 9 are evenly distributed and inclined on the rotating rod 9. The raw materials are stirred by the multiple stirring plates 10 to avoid the accumulation of raw materials in the drying tank 1 and improve the uniformity of drying.

[0017] A scraper 11 is connected to the rotating rod 9. The scraper 11 contacts the inner wall of the drying tank 1 and the groove wall of the groove 20. A turning plate 21 is connected to the inner side of the scraper 11. The upper and lower sides of the turning plate 21 are designed with arc surfaces. The scraper 11 continuously scrapes off the attached sticky raw materials by sticking to the inner wall of the drying tank 1 to prevent local overheating and coking. At the same time, the turning plate 21 turns the raw materials in three dimensions to avoid accumulation and improve the drying effect.

[0018] The connecting cover 4 is connected to filter plates 12 at both ends. A fan 13 is fixedly installed inside the connecting cover 4. An electric heating element 14 is connected inside the connecting cover 4. A working motor 15 is fixedly installed on one side of the filling hopper 3. A main synchronous pulley 16 is rotatably installed on one side of the filling hopper 3 through a bearing. A secondary synchronous pulley 17 is rotatably installed on the other side of the filling hopper 3 through a bearing. A toothed synchronous belt 18 is installed on both the main synchronous pulley 16 and the secondary synchronous pulley 17. The output shaft of the working motor 15 is connected to the main synchronous pulley 16. Multiple partitions 19 are connected at equal intervals on the toothed synchronous belt 18. The partitions 19 can effectively receive and prevent the material from slipping due to inertia during the conveying process. The equal interval design of the partitions 19 can realize the segmented conveying of the material and avoid the concentrated accumulation of a large amount of raw material at one time, which will affect the drying.

[0019] The working principle of this utility model is as follows: The main synchronous pulley 16 is rotated by the working motor 15. The main synchronous pulley 16, the auxiliary synchronous pulley 17, and the toothed synchronous belt 18 work together to make the toothed synchronous belt 18 move. Multiple equally spaced partitions 19 separate the various raw materials, thus transporting the raw materials from the connecting cover 4 side to the drying tank 1 in segments. This avoids the accumulation and uneven heating caused by filling a large amount of raw materials at once. The fan 13 blows air heated by the electric heating element 14 to dry the raw materials. When the hot air is blown into the drying tank 1, the blown air is guided by the conical design of the groove 20, thereby enhancing the airflow heat exchange efficiency. The drive motor 8 rotates the rotating rod 9 to drive the stirring plate 10 and the scraper 11 to rotate. The stirring plate 10 stirs the raw materials, and the scraper 11 scrapes off the raw materials adhering to the tank wall and the groove wall 20 to prevent the raw materials from carbonizing due to local overheating. The bottom raw materials are turned to the top by the turning plate 21 to achieve uniform heating of the raw materials.
