Description

Technical Field

[0001] The utility model relates to the field of biomass pellet fuel preparation, in particular to a pelletizing machine for efficiently preparing biomass pellet fuel. Background Art

[0002] Biomass pellets are made from raw materials such as biomass straw and forestry waste. They can be used as feed for livestock in large farms, for civil heating and living energy, and as fuel for industrial boilers and kilns. In the process of manufacturing biomass pellet fuel, in order to increase the pelleting speed, it is very necessary to use a pelletizer. This device can make the imported raw materials into pellets through extrusion, segmentation and other procedures.

[0003] During the pelletizing process, researchers discovered that biomass pellets reach a high temperature at the pelletizer outlet, resulting in a loose structure that easily breaks, affecting the yield rate of the product. Therefore, there is an urgent need to improve the pelletizer currently used to produce biomass pellet fuel. Utility Model Content

[0004] The main purpose of the utility model is to provide a pelletizing machine for efficiently preparing biomass pellet fuel, which is used to solve the problems mentioned in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A pelletizing machine for efficiently preparing biomass pellet fuel includes a base, a material pipe is fixed on the base, a feed hopper is provided at the top of one side of the material pipe, and the bottom of the feed hopper is connected to the inner cavity of the material pipe. A forming disk is fixedly embedded on the other side of the material pipe, and a partition is sealed and installed in the material pipe on the right side of the forming disk, and a cooling chamber is left between the forming disk and the partition. A metal cooling pipe is installed in the cooling chamber. A conical hole is provided on the partition, and a forming hole is provided on the forming disk. The conical holes correspond to the forming holes one by one, and the conical holes and the forming holes are connected by a metal cooling pipe. The lower end of the cooling chamber is connected to a water inlet pipe, and the upper end of the cooling chamber is connected to a water outlet pipe. The cooling chamber is provided with flowing cooling water.

[0007] Furthermore, a mounting seat is fixed on one side of the material pipe, and a horizontal motor is fixed on one side of the mounting seat. The power output shaft of the motor rotates and penetrates into the material pipe and is connected to the spiral blade shaft.

[0008] Furthermore, an inverted L-shaped support frame is fixed to one side of the material pipe, a vertical hydraulic push rod is installed on the support frame, and a pelletizing blade is installed at the bottom end of the hydraulic push rod.

[0009] Furthermore, the left and right ends of the metal cooling pipe are sealedly connected to the forming disk and the partition respectively, and the aperture of the forming hole is the same as the inner diameter of the metal cooling pipe.

[0010] Furthermore, a material guide plate is fixed on one side of the base, and a collection box is provided at the lower end of the material guide plate.

[0011] The present invention also includes other components that enable the efficient biomass pellet fuel pelletizer to function properly. These devices and components utilize conventional techniques in the art. Furthermore, any devices and components not otherwise specified in the present invention utilize conventional techniques in the art, such as the motor and hydraulic push rod described herein. During implementation, appropriate device or component models may be selected based on the specific work scenario.

[0012] The working principle of this utility model is as follows: raw materials are poured from the feed hopper into the feed pipe, where they are pushed toward the side of the partition by the spiral blade shaft. The raw materials pass through the tapered hole, the metal cooling pipe, and the forming hole to complete the forming process. Then, a hydraulic push rod pushes the pelletizing blade downward to complete the pelletizing process. The metal cooling pipe has excellent thermal conductivity. While the raw materials are in the metal cooling pipe, the cooling water flowing through the cooling chamber continuously removes heat from the raw materials, accelerating the cooling and hardening of the raw materials, improving their density, and thus increasing the yield rate of the product.

[0013] Compared with the prior art, the utility model has the following beneficial effects: accelerating the cooling and hardening of biomass particles during discharge, avoiding loose and broken structures, and improving the yield rate of products. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0017] The present invention will be described in further detail below with reference to the accompanying drawings and specific implementation methods.

[0018] Example:

[0019] like Figures 1-2As shown, a pelletizing machine for efficiently preparing biomass pellet fuel includes a base 1, on which a material pipe 2 is fixed, and a feed hopper 15 is provided at the top end of one side of the material pipe 2, and the bottom of the feed hopper 15 is communicated with the inner cavity of the material pipe 2. A forming disc 4 is fixedly embedded on the other side of the material pipe 2, and a partition 3 is sealed and installed in the material pipe 2 on the right side of the forming disc 4, and a cooling chamber 6 is left between the forming disc 4 and the partition 3. A metal cooling pipe 5 is installed in the cooling chamber 6. A conical hole 31 is provided on the partition 3, and a forming hole 41 is provided on the forming disc 4. The conical hole 31 corresponds to the forming hole 41 one by one, and the conical hole 31 and the forming hole 41 are communicated through the metal cooling pipe 5. The lower end of the cooling chamber 6 is connected to a water inlet pipe 7, and the upper end of the cooling chamber 6 is connected to a water outlet pipe 8. The cooling chamber 6 is provided with flowing cooling water.

[0020] Furthermore, an inverted L-shaped support frame 12 is fixed to one side of the feed pipe 2. A vertical hydraulic push rod 13 is mounted on this support frame 12, and a pelletizer blade 14 is attached to the bottom end of the hydraulic push rod 13. A mounting base 9 is fixed to one side of the feed pipe 2. A horizontal motor 10 is fixed to one side of the mounting base 9. The power output shaft of motor 10 rotates and penetrates the feed pipe 2 and is connected to the spiral blade shaft 11. A guide plate 16 is fixed to one side of the base 1, and a collection box 17 is located at the lower end of the guide plate 16. The left and right ends of the metal cooling pipe 5 are sealed to the forming plate 4 and the partition plate 3, respectively. The diameter of the forming hole 41 is the same as the inner diameter of the metal cooling pipe 5.

[0021] The operating principle of this utility model's efficient biomass pellet fuel pelletizer is as follows: raw material is poured from a feed hopper 15 into a feed pipe 2, where it is propelled toward a partition 3 by a spiral blade shaft 11. The raw material passes sequentially through a tapered hole 31, a metal cooling pipe 5, and a forming hole 41 to complete the forming process. Subsequently, a hydraulic push rod 13 pushes the pelletizing blade 14 downward to complete the pelletizing process. The metal cooling pipe 5 has excellent thermal conductivity. While the raw material is in the metal cooling pipe 5, flowing cooling water flows through the cooling chamber 6, continuously removing heat from the raw material, accelerating its cooling and hardening, improving its density, and thus increasing the yield rate of the product.
