Description

Technical Field

[0001] This utility model relates to the field of biomass pellet production technology, specifically a rice husk-enhanced biomass pellet production device. Background Technology

[0002] Rice husk-reinforced biomass pellets primarily use rice husks as the main raw material. Rice husks are widely available and are a significant byproduct of rice processing. Small amounts of binders or other additives may also be added to improve pellet formation and performance. They can serve as a high-quality biomass fuel to replace traditional fossil fuels such as coal and natural gas, and are widely used in industrial boilers, heating boilers, and thermal power generation, providing heat and electricity for production and daily life. In some rural areas or small businesses, they can also be used for home heating and cooking.

[0003] Chinese utility model patent CN217796585U discloses a biomass pellet production device, including a box with an inlet and an outlet. The box is equipped with a first pulverizing section and a second pulverizing section, both used for pulverizing and pelletizing biomass. The first pulverizing section is horizontally distributed, and the second pulverizing section is vertically distributed. An air supply mechanism is connected to the box for supplying downward air into the box. The air outlet of the air supply mechanism extends into the box, and an air heating mechanism is provided at the air outlet for heating the downward air. This utility model proposes a combined crushing mechanism with a crushing section one and a crushing section two to crush biomass into biomass pellets. The crushing section one is arranged horizontally, while the crushing section two is arranged vertically to improve crushing efficiency. By incorporating an air supply mechanism on the housing to deliver downward airflow and an air heating mechanism within the air supply mechanism, not only is the efficiency of biomass entering the housing improved, but the material to be crushed is also dried, thereby reducing material agglomeration and obtaining looser granular biomass, improving the degree of crushing, and reducing the amount of biomass retained in the housing.

[0004] However, during the use of this utility model, due to the large size of the biomass pellets, after the raw materials are crushed, they need to be extruded and molded. However, the device does not have a corresponding molding structure, which affects the production efficiency and cannot meet the production needs. Therefore, a rice husk-enhanced biomass pellet production device is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a rice husk-enhanced biomass pellet production device, which has the advantage of facilitating the extrusion molding of raw materials. It solves the problem that due to the large size of biomass pellets, after the raw materials are crushed, they need to be extruded and molded, but the device does not have a corresponding molding structure, which affects production efficiency and fails to meet production needs.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a rice husk-enhanced biomass pellet production device, comprising a base and a crushing tank fixedly connected to the top of the base, wherein a conveying cylinder is fixedly installed on the top of the base, and a cutting and forming mechanism capable of cutting raw materials is provided at one end of the conveying cylinder.

[0007] The cutting and forming mechanism includes a support frame fixedly connected to the top of the base. A first motor is fixedly installed on the top of the support frame. A rotating disk is fixedly connected to the output shaft of the first motor. A cutting blade is slidably connected inside the support frame. A hinge is fixedly connected to the side of the cutting blade near the rotating disk. A hinge rod is hinged between the rotating disk and the hinge.

[0008] The cutting blade is fixedly connected to positioning blocks extending into the support frame on both the left and right sides. The inner wall of the support frame is provided with positioning grooves that are adapted to the positioning blocks. The end of the conveying cylinder near the support frame is fixedly connected to an extrusion head. The extrusion head is provided with an extrusion hole that communicates with the conveying cylinder.

[0009] A feeding pipe is fixedly connected between the conveying cylinder and the crushing tank, and a heating jacket is fixedly installed on the outside of the conveying cylinder;

[0010] A feeding hopper extending into the hopper is fixedly installed on one side of the pulverizing tank, and a dryer is fixedly installed on the side of the pulverizing tank away from the feeding hopper.

[0011] Furthermore, a second motor is fixedly connected to the top of the base away from the support frame, a transmission gear is fixedly connected to the output shaft of the second motor, a driven gear that meshes with the transmission gear is rotatably connected to one end of the conveying cylinder, and a spiral extrusion rod that can rotate simultaneously with the driven gear is rotatably connected inside the conveying cylinder.

[0012] Furthermore, a gearbox is fixedly installed on the top of the pulverizing tank, a third motor is fixedly installed on the top of the gearbox, and two pulverizing blade holders are rotatably connected inside the pulverizing tank.

[0013] Compared with the prior art, this utility model provides a rice husk-enhanced biomass pellet production device, which has the following beneficial effects:

[0014] 1. This rice husk-enhanced biomass pellet production device uses a first motor to drive a rotating disk, which in turn drives a hinge rod to rotate. A cutting blade and a hinge mechanism are also included, allowing the hinge rod to move the cutting blade back and forth, thus cutting the biomass pellets extruded from the extruder head. This achieves the desired biomass pellet forming effect and improves production efficiency.

[0015] 2. This rice husk-enhanced biomass pellet production device uses a second motor to simultaneously drive the transmission gear and the driven gear to rotate. The driven gear then drives the spiral extruder to rotate, allowing the spiral extruder to extrude the biomass raw material inside the conveying cylinder to the extrusion head, thus achieving the extrusion molding effect. This solves the problem that, due to the large size of biomass pellets, after the raw material is crushed, it needs to be extruded and molded, but the device lacks a corresponding molding structure, which affects production efficiency and fails to meet production needs.
