Description

Technical Field

[0001] This utility model relates to the field of conveying equipment, and more specifically, to a pellet mill conveying device. Background Technology

[0002] Biomass fuel refers to fuel made by burning biomass materials, which are generally agricultural and forestry wastes (such as straw, sawdust, bagasse, rice husks, etc.). The production of biomass fuel requires processes such as crushing, mixing, extrusion, and drying. It is a new type of clean fuel that can be directly burned and can be processed into pellets and then transported to the next equipment for further processing.

[0003] The utility model patent application CN 217410687 U discloses a pellet mill for producing biomass fuel, comprising a pellet mill body with a feeding mechanism on its side; the pellet mill body includes a feed inlet connected to the feed mechanism below and communicating with a storage silo; a mixing mechanism is provided inside the storage silo; a partition is movably provided at the bottom of the storage silo and connected to a blocking mechanism; a forming cylinder is provided below the partition, with a forming cavity inside the forming cylinder; a forming rod is provided below the forming cylinder, matching the forming cavity; a hydraulic cylinder is connected to the bottom of the forming rod, and an oil pump is externally connected to the hydraulic cylinder; the application also includes a controller electrically connected to the feed mechanism, the mixing mechanism, the blocking mechanism, and the oil pump; this pellet mill simultaneously possesses feeding, mixing, and forming functions, effectively improving production efficiency and exhibiting a high degree of automation, making it suitable for widespread adoption.

[0004] In the above-disclosed structure, the material is transported by conveyor belt. However, spiral blades cannot be installed through the conveying pipe, so forced conveying is not possible. This means that it cannot handle large conveying angles, cannot feed vertically, has poor adaptability, and when conveying particles through the pipe, the frictional resistance is large, which can easily cause overheating and jamming. Furthermore, it cannot be separated for protection, resulting in poor safety and stability, and thus requires improvement. Utility Model Content

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a pellet mill conveying device. The device uses a conveying shaft inside the conveying pipe to install spiral blades and a first friction plate, which can rotate and convey the material. A motor and a threaded shaft are installed through a mounting frame, and a second friction plate is installed in conjunction with a threaded cylinder. The device can be combined and connected for drive control. In case of interference, it can slide and separate, which improves safety and stability, ensures conveying efficiency, and is conducive to combined use.

[0006] To solve the above problems, the present invention adopts the following technical solution.

[0007] A pellet mill conveying device includes a conveying pipe, a discharge pipe fixedly connected to one end surface of the conveying pipe, a conveying shaft rotatably mounted inside the conveying pipe, a helical blade fixedly connected to the outer surface of the conveying shaft, the helical blade rotatably mounted inside the conveying pipe, a first friction plate fixedly connected to one end of the conveying shaft, a support bearing assembled and mounted on one side of the first friction plate, the support bearing rotatably mounted to one end of the conveying pipe, a mounting frame fixedly connected to one end of the conveying pipe, a motor fixedly mounted to one end of the mounting frame, a threaded shaft fixedly connected to the shaft end of the motor, a threaded cylinder threadedly mounted on one end surface of the threaded shaft, a second friction plate fixedly connected to one end of the threaded cylinder, one side surface of the second friction plate tightly abutting against one side surface of the first friction plate, a locking nut threadedly mounted on one end of the threaded shaft, the locking nut being press-fitted to one end of the threaded cylinder.

[0008] Furthermore, both the first friction plate and the second friction plate are located inside the mounting bracket and at the upper end of the delivery pipe.

[0009] Furthermore, a handle is fixedly connected to one end surface of the threaded cylinder, and the handle is rotatably mounted inside the mounting bracket.

[0010] Furthermore, the support bearing is rotatably sleeved on one end surface of the conveyor shaft, and is connected to the second friction plate through the first friction plate. Combined with the threaded cylinder mounting handle, it can be manually adjusted for alignment, which is beneficial for friction drive. When the interference resistance is large, it can slide and separate, which improves the safety of motor rotation and is conducive to combined use.

[0011] Furthermore, a heat sink is fixedly connected to the outer surface of the conveying pipe, and a cleaning ring is slidably installed on one end surface of the conveying pipe.

[0012] Furthermore, the cleaning ring has an annular groove inside, and an annular brush is fixedly connected to the inner side of the annular groove.

[0013] Furthermore, the annular groove is slidably fitted onto the edge of the heat sink, and the annular brush is slidably connected to the gap of the heat sink. The heat sink is connected to the surface of the conveying pipe, and the annular brush is installed in conjunction with the cleaning ring. This can assist in the heat dissipation of the conveying pipe and can also slide to clean, avoiding dust adhesion of particulate materials, improving the cooling effect, and facilitating combined use.

[0014] Compared with existing technologies, the advantages of this utility model are:

[0015] (1) This scheme uses a conveying shaft inside the conveying pipe to install spiral blades and a first friction plate, which can rotate and convey. The motor and threaded shaft are installed through the mounting bracket, and the second friction plate is installed in combination with the threaded cylinder. They can be connected together for drive control. When there is interference, they can slide and separate, which improves safety and stability, ensures conveying efficiency, and is conducive to combined use.

[0016] (2) The first friction plate is connected to the second friction plate. Combined with the screw cylinder mounting handle, the alignment can be manually adjusted, which is beneficial for friction drive. When the interference resistance is large, it can slide and separate, which improves the safety of motor rotation and is conducive to combined use.

[0017] (3) By connecting heat sinks to the surface of the conveying pipe and installing an annular brush in conjunction with the cleaning ring, the conveying pipe can be cooled and cleaned by sliding, avoiding dust adhesion of particulate materials, improving the cooling effect, and facilitating combined use.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1 , Figure 3 and Figure 5A pellet mill conveying device includes a conveying pipe 1, with a discharge pipe 11 fixedly connected to one end. The conveying pipe 1 can be assembled and installed on the pellet mill, thus inserting into the granular material to extract and convey the granular material upwards for loading into the next process equipment, facilitating production. A conveying shaft 12 is rotatably mounted inside the conveying pipe 1, and a spiral blade 13 is fixedly connected to the outer surface of the conveying shaft 12. The spiral blade 13 can rotate to forcefully convey the granular material, which is efficient and stable. The spiral blade 13 is rotatably mounted inside the conveying pipe 1. A first friction plate 14 is fixedly connected to one end of the conveying shaft 12, and a support bearing 15 is assembled and installed on one side of the first friction plate 14. The support bearing 15 is rotatably mounted to one end of the conveying pipe 1. A mounting frame 16 is fixedly connected to one end of the conveying pipe 1, and a motor 17 is fixedly mounted to one end of the mounting frame 16. A threaded shaft 18 is fixedly connected to the shaft end of the motor 17, and a threaded surface is installed on one end of the threaded shaft 18. The device includes a threaded cylinder 2, one end of which is fixedly connected to a second friction plate 21. One side surface of the second friction plate 21 is tightly connected to one side surface of the first friction plate 14. A locking nut 22 is threaded onto one end of a threaded shaft 18, which is pressed tightly onto one end of the threaded cylinder 2. In use, the threaded cylinder 2 can be manually adjusted to push the second friction plate 21 against the surface of the first friction plate 14. Then, the locking nut 22 is rotated to lock and position the device, preventing loosening. This combination allows for positioning. The motor 17 drives the threaded shaft 18 and the threaded cylinder 2 to rotate, thereby using the friction of the second friction plate 21 to drive the first friction plate 14, which in turn drives the conveyor shaft 12 and the spiral blade 13 to rotate. This is convenient and efficient. However, in the event of jamming or interference, the friction is insufficient to drive the conveyor shaft 12 to rotate, causing the second friction plate 21 and the first friction plate 14 to slip and spin freely. This prevents damage to the motor 17, improves safety and stability, and facilitates combined use.

[0027] Please see Figure 2 and Figure 3 The first friction plate 14 and the second friction plate 21 are both located inside the mounting bracket 16 and at the upper end of the conveying pipe 1. A handle 23 is fixedly connected to one end surface of the threaded cylinder 2. The handle 23 is rotatably installed inside the mounting bracket 16. The support bearing 15 is rotatably sleeved on one end surface of the conveying shaft 12 and connected to the second friction plate through the first friction plate. Combined with the threaded cylinder mounting handle, the alignment can be manually adjusted, which is beneficial for friction drive. When the interference resistance is large, it can slide and separate, which improves the safety of motor rotation and is conducive to combined use.

[0028] Please see Figure 2 and Figure 4A heat sink 24 is fixedly connected to the outer surface of the conveying pipe 1. A cleaning ring 25 is slidably installed on one end of the conveying pipe 1. The cleaning ring 25 has an annular groove 26 inside. An annular brush 27 is fixedly connected to the inner side of the annular groove 26. The annular groove 26 is slidably sleeved on the edge of the heat sink 24. The annular brush 27 is slidably connected to the gap of the heat sink 24. By connecting the heat sink to the surface of the conveying pipe and installing the annular brush with the cleaning ring, the conveying pipe can be assisted in heat dissipation and can be slidably cleaned to avoid dust adhesion of particulate materials, improve the cooling effect, and facilitate combined use. The heat sink 24 increases the surface area, which can improve the heat dissipation effect. Friction heat is generated during the particle conveying process, which can be quickly cooled to improve safety and stability and facilitate use. Manually pushing the cleaning ring 25 can be combined with the annular brush 27 to clean and maintain the surface, preventing particulate dust from covering and affecting the cooling effect, which is conducive to combined use.

[0029] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
