Description

Technical Field

[0001] This utility model relates to the field of material conveying technology, and in particular to a conveying mechanism for biofuel production. Background Technology

[0002] In the field of biofuel processing, with increasing environmental awareness and growing demand for renewable energy, biofuels, as a clean and renewable energy source, have received widespread attention for their development and utilization. The biofuel production process involves several key stages, among which crushing, dust removal, and transportation are crucial steps that directly affect the quality of the biofuel, production efficiency, and the safety of the production environment.

[0003] Currently, traditional biofuel transportation and crushing processes generate a large amount of dust. This dust not only severely pollutes the working environment but also endangers the health of operators, posing significant safety hazards to production. Therefore, this application provides a conveying mechanism for biofuel production to meet this need. Utility Model Content

The hopper is equipped with a crushing mechanism, the conveying pipe is located at the bottom of the hopper, the centrifugal fan is mounted on one side of the hopper, and an air duct is provided on the side wall of the hopper near the centrifugal fan. The air inlet of the centrifugal fan is connected to the air duct, and a cloth bag is mounted on the air outlet of the centrifugal fan.

[0006] Optionally, the outlet of the centrifugal fan is vertically downward, and the outlet flange of the centrifugal fan is connected to a connecting pipe, with the cloth bag fitted onto the connecting pipe.

[0009] Optionally, a feed inlet is provided at one end of the top of the conveying pipe, and a discharge outlet is provided at the bottom of the conveying pipe at the end away from the feed inlet. A spiral conveying shaft is rotatably installed inside the conveying pipe, and a conveying motor for driving the spiral conveying shaft to rotate is installed at one end of the conveying pipe.

[0010] Optionally, the bottom of the hopper is configured as a bucket-shaped structure and connected to the feed inlet flange.

[0011] Optionally, the crushing mechanism includes a pair of crushing rollers that are installed side by side and rotated inside the hopper. Several cutters are provided on the side wall of the crushing rollers. The cutters on the pair of crushing rollers are staggered. A pair of crushing motors are installed on the side wall of the hopper. The output shafts of the pair of crushing motors are respectively connected to the pair of crushing rollers for transmission.

[0026] like Figure 1 , Figure 2 and Figure 5 As shown, an embodiment of this utility model provides a conveying mechanism for biofuel production, including a base plate 1 and a hopper 2. In this embodiment, a conveying pipe 3 is provided below the hopper 2. A feed inlet 10 is opened at one end of the top of the conveying pipe 3, and a discharge outlet 11 is provided at the bottom end away from the feed inlet 10. A spiral conveying shaft 21 is horizontally installed inside the conveying pipe 3. A conveying motor 13 is installed at one end of the conveying pipe 3. The spiral conveying shaft 21 is driven to rotate by the conveying motor 13 to realize the directional conveying of biofuel. The spacing between the spiral blades of the spiral conveying shaft 21 inside the conveying pipe 3 is 100-150mm, and the gap between the diameter of the spiral blades and the inner diameter of the conveying pipe 3 is controlled at 5-8mm to ensure conveying efficiency and sealing.

[0027] like Figure 1 and Figure 2 As shown, a crushing mechanism is installed inside the hopper 2. The crushing mechanism includes a pair of crushing rollers 8 installed side by side and rotating. Several cutters 9 are evenly distributed on the sidewalls of the crushing rollers 8, and the cutters 9 on the pair of crushing rollers 8 are staggered to form a shearing crushing structure. The crushing rollers 8 are fixed to the sidewalls of the hopper 2 by bearing seats. A pair of crushing motors 12 are installed on the outer wall of the hopper 2, and the output shafts of the crushing motors 12 are connected to the crushing rollers 8 through a coupling.

[0028] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, a centrifugal fan 6 is mounted on one side of the hopper 2. An air duct 7 is installed on the side wall of the hopper 2 near the centrifugal fan 6. The air inlet of the centrifugal fan 6 is connected to the flange of the air duct 7, and the air outlet is vertically downward and connected to the flange of the connecting pipe 15. A cloth bag 16 is fitted at the bottom of the connecting pipe 15. A boss 17 is provided on the side wall of the connecting pipe 15 near the bottom. A fastening strap 18 is nested on the boss 17. The fastening strap 18 is made of elastic rubber, and ear blocks 19 are provided at both ends of its break. A pair of ear blocks 19 are threadedly connected by fastening bolts 20. By tightening the fastening bolts 20, the fastening strap 18 can be tightened, thereby firmly fixing the cloth bag 16 to the connecting pipe 15. This allows for quick assembly, disassembly, and sealing of the cloth bag 16. The crushing roller 8 is located below the air duct 7, ensuring that the crushed material directly enters the conveying pipe 3.

[0029] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the bottom of the hopper 2 is configured as a bucket-shaped structure and is connected to the flange of the feed inlet 10, so that the material in the hopper 2 can smoothly enter the conveying pipe 3. The base plate 1 is set at the bottom of the conveying pipe 3. The bottom of the side wall of the hopper 2 is provided with a protruding plate 14. Multiple columns 4 are fixedly connected between the protruding plate 14 and the base plate 1. Multiple brackets 5 are also vertically arranged on the base plate 1. The top of the bracket 5 has an arc-shaped support arm nested with the conveying pipe 3, which supports and stabilizes the conveying pipe 3 and prevents the conveying pipe 3 from shaking during the material conveying process.

[0030] The working principle of the technical solution provided by this utility model is as follows: First, the biofuel feedstock is fed into hopper 2. The crushing motor 12 is started, driving a pair of crushing rollers 8 to rotate relative to each other. The cutter 9 shears and tears the biofuel feedstock, breaking large pieces into smaller particles for easier subsequent conveying and processing. During the crushing process, a certain amount of dust is generated. At this time, the centrifugal fan 6 is started. The centrifugal fan 6 extracts the air and dust from hopper 2 through duct 7. After entering the centrifugal fan 6, the air and dust enter the filter bag 16 through the outlet pipe 15. The filter bag 16 has a filtering function; air can pass through the filter bag 16 and be discharged, while dust is trapped inside, achieving gas-solid separation. This achieves dust removal and reduces dust pollution.

[0031] The crushed biofuel pellets enter the conveying pipe 3 through the feed inlet 10. The conveying motor 13 is started, which drives the screw conveyor shaft 21 to rotate. The screw conveyor shaft 21 conveys the biofuel pellets in the conveying pipe 3 from one end of the feed inlet 10 to the other end of the discharge outlet 11, and finally outputs them from the discharge outlet 11, completing the biofuel conveying process.

[0032] This utility model encompasses any substitutions, modifications, equivalent methods, and solutions made within the spirit and scope of this utility model. To provide the public with a thorough understanding of this utility model, specific details are described in detail in the following preferred embodiments; however, those skilled in the art will fully understand this utility model even without these detailed descriptions. Furthermore, to avoid unnecessary confusion regarding the essence of this utility model, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0033] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
