[0002] Biomass fuel rods are made of pure pine and oak sawdust through mechanical extrusion. They have the characteristics of high combustion value, no pollution, and strong firepower. They are essential products for boiler fuel in hotels, baths, schools, shopping malls, etc. The processing flow of biomass fuel rods includes raw material collection, crushing, rod making, drying, packaging, storage and transportation. The packaging needs to be packaged into products of different specifications according to customer requirements, such as bagged, bulk, etc.

[0003] When packing, a quantitative packing machine is needed. The quantitative packing machine includes silo, weighing, packing and other parts. Since biomass fuel rods are susceptible to moisture and there are certain debris, the quality and shelf life of the packaged product will be affected;

[0004] After searching, the publication (announcement) number CN215707690U discloses a biomass pellet packaging device. Although it has a heating and drying function, the heating area of ​​this method is small, and the water vapor generated after heating cannot be quickly discharged from the storage tank; secondly, the dust suction channel arranged inside the rotating tube is too long, and the dust far away from the side of the ash storage bin is difficult to be collected, and the material is fed through the rotating tube. Since there is a certain amount of material inside the storage tank, the pressure of the material and the force generated by the rotation of the rotating tube will produce a crushing pressure on the material, increase dust, and affect the quality of the packaged material;

[0005] In order to solve the above problems, the present application proposes a biomass fuel rod quantitative packaging machine. Utility Model Content

[0029] See also Figure 1-4 As shown, the utility model is a quantitative packaging machine for biomass fuel rods, including a frame 1 and a storage tank 2 installed on the frame 1, the bottom of the storage tank 2 is connected to a processing channel 3, the bottom of the processing channel 3 is provided with a processing box 4, the processing box 4 is inclined, the end of the processing channel 3 is connected to a feeding pipe 5, a weight scale 6 located directly below the feeding pipe 5 is installed on the frame 1 through a bracket, and clamps 8 for clamping the packaging bag outside the feeding pipe 5 are also provided on both sides of the feeding pipe 5, a screen 9 is provided at the bottom of the processing box 4, and an electric heating pipe 10 located at the lower end of the screen 9 is provided at the upper end of the processing box 4. 4 is provided with an exhaust net 11 corresponding to the screen 9, a fan unit 12 located on the exhaust net 11 is provided outside the processing box 4, and a preheating channel 13 communicating with the processing box 4 is provided at the bottom of the frame 1. The processing channel 3, the screen 9, and the electric heating tube 10 in this embodiment combine feeding, screening, and drying to ensure the packaging quality of the biomass fuel rods. At the same time, the heat generated by the electric heating tube 10 is used to preheat the biomass fuel rods at the bottom of the frame 1, with high energy utilization, ensuring drying efficiency and effect. The set feeding pipeline 5 and clamping plate 8 can realize quantitative packaging to meet customer needs.

[0030] Among them, the bottom of the storage tank 2 is inclined, and the inclined end is connected to the processing channel 3. The preheating channel 13 is located at the bottom of the frame 1 and is also inclined. The two ends of the preheating channel 13 are interconnected. The inclined upper end of the preheating channel 13 is connected to the connecting channel 14. The lower end of the connecting channel 14 is connected to the upper end of the fan unit 12. The inclination of the storage tank 2 in this embodiment prevents the material from being accumulated and blocked inside the storage tank 2, and plays a guiding role. The preheating channel 13 uses the heat generated by the electric heating tube 10 to heat the bottom of the storage tank 2, thereby ensuring the drying efficiency of the material.

[0031] Among them, the processing box 4 is fixed integrally with the processing channel 3, and a collecting box 15 is arranged inside the processing box 4. The collecting box 15 is located directly below the screen 9. In this embodiment, the debris passing through the screen 9 is automatically collected by the collecting box 15, and no power equipment is required. The structure is simple and practical, and the collecting effect is good.

[0032] Among them, the electric heating tube 10 heats the biomass fuel rods located in the processing box 4 and discharges the heated airflow and the water vapor formed by the heating from the exhaust network 11 to the outside of the processing box 4 through the fan unit 12. In this embodiment, the fan unit 12 can quickly send the airflow with water vapor out from the inside of the processing channel 3 to ensure the drying effect and efficiency of the material.

[0033] Among them, the frame 1 is equipped with an electric cylinder 7 through a bracket, and a clamp 8 is fixed at the output end of the electric cylinder 7. The clamp 8 matches the outer contour of the discharge pipe 5, and the bottom of the discharge pipe 5 is chamfered. In this embodiment, the packaging bag is clamped by the clamp 8 and the discharge pipe 5, which is convenient for use and ensures the stability of the packaging bag. The chamfered setting makes it easy to insert the packaging bag into the outside of the discharge pipe 5.

[0034] Among them, the storage tank 2, the processing channel 3, and the discharge pipe 5 are interconnected.

[0035] Among them, the biomass fuel rods in the processing channel 3 are screened by the screen 9 and the debris is collected in the collection box 15. In this embodiment, the screen 9 is integrally connected with the processing channel 3, which does not affect the falling of the material and can also play a screening role. In this process, the material will not be squeezed to increase the amount of debris. The collection box 15 is in the form of a drawer, which can be dumped after collecting a certain amount.

[0036] It can be understood that the utility model is equipped with coordinated processing channels 3, screens 9, and electric heating tubes 10, which integrate feeding, screening, and drying to ensure the packaging quality of biomass fuel rods. At the same time, the heat generated by the electric heating tubes 10 is used to preheat the biomass fuel rods at the bottom of the rack 1, with high energy utilization to ensure drying efficiency and effect. The unloading pipes 5 and splints 8 can achieve quantitative packaging to meet customer needs.

[0037] A specific application of this embodiment is: the packaging bag is sleeved on the outside of the material discharge pipe 5, and the electric cylinder 7 is started to press the packaging bag between the material discharge pipe 5 and the clamping plate 8;

[0038] The biomass fuel rods are put into the storage tank 2, and an interception component for controlling the falling and stopping of the materials can be set in the storage tank 2. When the materials pass through the processing channel 3, the screen 9 screens the mixed slag and drops it into the collection box 15. The electric heating pipe 10 in the heated state heats the materials in the processing channel 3 to drain the moisture in the materials. The fan unit 12 works to introduce the air flow with water vapor into the preheating channel 13 through the exhaust net 11 through the connecting channel 14. The air flow is discharged from the end of the preheating channel 13 away from the connecting channel 14. During the process of the air flow in the preheating channel 13, the heat will be transferred to the underground end inside the frame 1 and preheat the biomass fuel rods. After passing through the processing channel 3, the screened and dried biomass fuel rods enter the unloading pipe 5 and are collected in the packaging bag;

[0039] The weight of the biomass fuel rods in the packaging bag is displayed on the weight scale 6. When the weight is reached, the sealing work is carried out. The distance between the weight scale 6 and the feeding pipe 5 is less than the height of the packaging bag, ensuring that the pressure of the packaging bag is fully applied to the weight scale 6 to ensure quantitative accuracy.
