Description

Technical Field

[0001] This utility model relates to the field of biomass pellet production technology, specifically to a feeding mechanism for biomass pelleting. Background Technology

[0002] Straw is a general term for the stems and leaves of mature crops. It usually refers to the residue left after harvesting wheat, rice, corn, potatoes, rapeseed, cotton, sugarcane, and other crops. In modern times, for resource recycling and reuse, straw is often processed into biomass pellets for secondary use.

[0003] However, in general production, the crushed material is manually fed into the hopper using tools. Because the crushed material is light, it is easy for the powder to accumulate at the bottom of the hopper, which affects the overall production effect. Moreover, large pieces of powder are easily mixed in, affecting granulation. Alignment and screening are required. Therefore, a feeding mechanism for biomass pellet granulation is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a feeding mechanism for biomass pelleting to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a feeding mechanism for biomass pelletizing, comprising a screw conveyor and a material cylinder, wherein the outer cylinder of the screw conveyor extends outward to form a connecting cylinder at the connection point with the material cylinder, the connecting cylinder being in communication with the material cylinder, and a screw tooth block is installed on the outer end of the screw conveyor corresponding to the connecting cylinder, the screw tooth block scraping the material in the material cylinder, and a vibrating screen for filtering the material is installed inside the material cylinder.

[0006] Preferably, one end of the vibrating screen is rotatably mounted inside the material cylinder, and the material cylinder is equipped with a support block for supporting the other end of the vibrating screen.

[0007] Preferably, a telescopic component is hinged between the bottom of the vibrating screen and the inner wall of the material cylinder. The telescopic component can lift one side of the vibrating screen and dump the screened material on the vibrating screen.

[0008] Preferably, the outer wall of the material cylinder is provided with a pouring opening, the bottom of the pouring opening corresponds to the rotating part of the vibrating screen, a baffle is hinged inside the pouring opening, and a locking device is provided between the baffle and the material cylinder, and a conveying plate is installed on the outer wall of the material cylinder corresponding to the lower end of the pouring opening.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: A feeding mechanism for biomass pelleting, by setting a spiral tooth block on one side of the corresponding material cylinder of the screw conveyor, increases the outer diameter of the screw conveyor rod of the screw conveyor, allowing it to extend to the lower end of the material cylinder. The tooth block shape increases the friction between the material and the screw conveyor, thereby scraping the material and causing it to fall into the screw conveyor for conveying. Since the material is relatively light, the vibration of the vibrating screen can cause the material cylinder to vibrate to a certain extent, further enabling the material to move downwards. The vibrating screen can screen out the material, isolating larger materials at the upper end of the vibrating screen. After a certain amount has accumulated, to avoid affecting the screening of the material, the telescopic component is activated and the tilting port is opened. The telescopic component lifts one end of the vibrating screen, allowing the larger materials to slide out from the tilting port along the inclined surface of the vibrating screen. The tilting baffle forms a springboard to send the larger materials to the conveying plate for processing. Attached Figure Description

[0013] 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 protection scope of the present utility model.

[0014] Please see Figure 1-2 This utility model provides a technical solution: a feeding mechanism for biomass pelleting, including a screw conveyor 1 and a material cylinder 2. The outer cylinder 11 of the screw conveyor 1 extends outward to form a connecting cylinder 3 at the connection point with the material cylinder 2. The connecting cylinder 3 is connected to the material cylinder 2. The screw conveying rod 12 of the screw conveyor 1 is equipped with a screw tooth block 4 at the outer end corresponding to the connecting cylinder 3. The screw tooth block 4 scrapes the material in the material cylinder 2. A vibrating screen 5 for filtering the material is installed inside the material cylinder 2.

[0015] One end of the vibrating screen 5 is rotatably installed inside the material cylinder 2, and the material cylinder 2 is equipped with a support block 6 for supporting the other end of the vibrating screen 5.

[0016] A telescopic component 7 is hinged between the bottom of the vibrating screen 5 and the inner wall of the material cylinder 2. The telescopic component 7 can lift one side of the vibrating screen 5 and dump the screened material on the vibrating screen 5.

[0017] The outer wall of the material cylinder 2 is provided with a pouring port 8. The bottom of the pouring port 8 corresponds to the rotating part of the vibrating screen 5. A baffle 9 is hinged inside the pouring port 8, and a locking fastener 10 is provided between the baffle 9 and the material cylinder. A conveying plate 13 is installed on the outer wall of the material cylinder 2 corresponding to the lower end of the pouring port 8.

[0018] Working Principle: In the biomass pelleting process, the crushed material is first fed into the feed cylinder 2. The screw conveyor 1 at the lower end feeds the material at a uniform speed. The vibrating screen 5 is then activated, screening the material and blocking larger pieces. Material meeting the standards passes through the vibrating screen 5 and reaches the lower end of the feed cylinder 2. The vibration of the vibrating screen 5 causes the feed cylinder 2 to vibrate, making it easier for the material to reach the lower end. The material is then conveyed by the screw conveyor 1. When material gets stuck at the lower end of the feed cylinder 2, it is removed by the screw conveyor 1. 4. The material at the lower end of the material cylinder 2 is scraped to fall into the screw conveyor 1. The screw tooth block 4 can increase the contact area between the screw conveyor 1 and the material cylinder 2. The material at the lower end of the material cylinder 2 is scraped to avoid material blockage. When it is necessary to process larger materials on the vibrating screen 5, the pouring port 8 is opened and the telescopic component 7 is activated. The telescopic component 7 lifts one end of the vibrating screen 5. The larger materials slide down with the inclined vibrating screen 5 through the pouring port 8 to the baffle 9, and finally fall into the conveying plate 13 to complete the cleaning of larger materials.

[0019] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
