Description

Technical Field

[0001] This utility model relates to the field of biomass pellet production technology, and more specifically, to a pellet mill for producing biomass pellets. Background Technology

[0002] Biomass pellets are produced by cold-forming and densifying crushed biomass straw, forestry waste, and other raw materials using pressure rollers and ring dies at room temperature. The density of the raw materials is generally 0.1–0.13 t / m³, and the density of the pellets after forming is 1.1–1.3 t / m³. This process facilitates storage and transportation and greatly improves the combustion performance of biomass. Biomass pellets are typically made from plant materials such as wood, corn stalks, wheat stalks, rice husks, and leaves. They are produced through crushing, thermoforming, and drying processes.

[0003] Existing biomass pellet mills require manual docking and collection of materials during pellet processing. Manual material collection is difficult to control due to the large amount of dust generated during material feeding, and the accuracy of material feeding height and position is low, leading to problems such as difficulty in ensuring proper docking and feeding, resulting in feeding failures.

[0019] 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.

[0020] As attached Figure 1-4 As shown, this utility model provides a pellet mill for producing biomass pellets, including a pellet mill 1. A biomass pellet collection auxiliary device 2 is provided at the front end of the pellet mill 1. The biomass pellet collection auxiliary device 2 includes a positioning and feeding collection component 21 and a feeding protection component 22. The positioning and feeding collection component 21 is provided at the lower front end of the pellet mill 1.

[0021] The positioning and feeding collection assembly 21 includes: a movable limiting groove 213, a sliding limiting block 214, a support frame 212, a collection frame 217, a movable roller assembly 215, a pull handle 216, and a pellet feeding connector 211. The lower rear end of the pellet feeding connector 211 is installed on the upper end of the pellet processing machine 1. The movable limiting groove 213 is opened inside the support frame 212. One end of the sliding limiting block 214 is detachably installed inside the movable limiting groove 213, and the other end of the sliding limiting block 214 is installed on the outer side wall of the collection frame 217. The lower end of the collection frame 217 is installed on the upper end of the movable roller assembly 215, and the front end of the pull handle 216 is installed on the outer side wall of the collection frame 217.

[0022] The material discharge protection assembly 22 includes: an electric hydraulic cylinder 224, a sealing cover plate 225, a telescopic discharge sleeve 226, a discharge pipe 221, and a discharge chute 223. The discharge chute 223 is opened on the inner and outer walls of the upper end of the support frame 212. The lower end of the electric hydraulic cylinder 224 is installed on the upper end of the support frame 212. The output end of the electric hydraulic cylinder 224 is installed on the upper end of the sealing cover plate 225. The upper end of the sealing cover plate 225 is installed on the lower end of the telescopic discharge sleeve 226. The upper end of the telescopic discharge sleeve 226 is installed on the lower end of the discharge pipe 221. The upper end of the discharge pipe 221 is installed on the lower front side of the particle discharge connector 211. The upper and lower ends of the sealing cover plate 225 are the same size as the upper end of the collection frame 217.

[0023] The specific implementation method is as follows: When using this utility model, the pellet processing machine 1 needs to be started for processing first. After the pellet processing machine 1 is started, the lower end can be positioned and collected by the collection frame 217. After the lower end of the collection frame 217 is completed, the upper end can be started to assist in the feeding work. When the feeding protection component 22 is performing the feeding work, it can be started by the electric hydraulic cylinder 224 at the upper end. After the electric hydraulic cylinder 224 is started, it drives the sealing cover plate 225 installed at the output end to move up and down. After being moved, the telescopic discharge sleeve 226 installed at the upper end moves and extends. After the telescopic discharge sleeve 226 has extended and retracted, the sealing cover plate 225 set at the lower end is installed at the upper end of the collection frame 217 to seal the upper end. This can effectively prevent the problem of smoke spreading and material leakage when the collection frame 217 is collecting materials. After the positioning discharge collection component 21 and the discharge protection component 22 work together to complete the discharge work, the device greatly enhances the integrity of the entire device's discharge and avoids the problem of discharge failure caused by incorrect discharge docking position.

[0024] The working principle of this utility model is as follows: When using this utility model, the pellet processing machine 1 needs to be started first for processing. After the pellet processing machine 1 starts processing, the lower end can be positioned and collected by the collection frame 217. After the collection frame 217 has completed the lower end collection, the upper end can be started to assist in the feeding work. When the feeding protection component 22 is performing the feeding work, it can be started by the electric hydraulic cylinder 224 at the upper end. After the electric hydraulic cylinder 224 is started, it drives the sealing cover plate 225 installed at the output end to move up and down. After the sealing cover plate 225 moves up and down, it drives the telescopic feeding sleeve 226 installed at the upper end to move and extend. After the telescopic feeding sleeve 226 has extended and retracted, the lower end of the sealing cover plate 225 at the lower end is connected to the upper end of the collection frame 217 to perform the upper end sealing work. This can effectively prevent the problem of the feeding smoke spreading everywhere and the feeding leakage when the collection frame 217 is performing the collection work.
